Disclosed is a protective paint spraying equipment for a wheel hub including a centering device, a paint spraying device and a review device. This equipment covers a protective paint film with a certain hardness and transparency on a QR code of the hub, effectively avoiding damage to the QR code by the hub during the loading process, ensuring full flow traceability of the hub.

Protective paint spraying equipment for a wheel hub

A hub chuck, includes a clamping center shaft, a top cover plate, a middle step gear and a tapered bottom plate. In a three-layer structure of the cover plate, the step gear and the tapered bottom plate of the chuck, the maximum outer ring diameter of the cover plate is smaller than that of the step gear, the minimum outer ring diameter of the step gear is smaller than that of the tapered bottom plate, the lower part of the step gear and the upper surface of the tapered bottom plate form a ring groove, a lower rim of a hub can be caught in the ring groove, and tapered teeth at the upper part of the step gear can be pressed to an inner wheel lip.

Hub chuck, hub fixture and X-ray detecting apparatus

A mold surface repairing process, the process flow of which is as follows: first sand blasting&#x2014;defect identification&#x2014;repairing welding&#x2014;coarse grinding&#x2014;semi-finishing grinding&#x2014;finishing grinding&#x2014;secondary sand blasting&#x2014;mold heating&#x2014;spray paint. The disclosure provides a combination of automatic equipment, special grinding tools and finishing grinding process, which ensures the quality and efficiency of the mold repair and reduces the labor force.

Mold surface repairing process

The invention discloses an automatic powder cleaning system for mixed-line hub bolt holes and a combined powder cleaning gun. The powder cleaning system comprises a control system, a recognition system, a powder cleaning robot, a gun storage and an accessory device. A plurality of combined powder spraying guns are arranged in the gun storage, and a quick disassembly fixture is arranged at the end of the powder cleaning robot. The powder cleaning system adopts robot programming and hub recognition technologies; according to the sizes of different hub bolt holes, ball sockets and platforms as well as product standards, the robot automatically and quickly selects different types of combined powder cleaning guns; after powder spraying under the condition that the hub is not provided with protectors, the head of the central gun barrel absorbs powder at the bolt hole, and the ball socket and platform gun barrel absorbs powder at the ball socket and platform of the bolt hole; protective small plugs for bolt holes are replaced by the powder cleaning gun, so that a large number of small plugs are avoided, the production cost is reduced, and the environmental pollution caused by paint drop of the small plugs is prevented; and the absorbed powder can be reused, so that the automatic powder cleaning system and the combined powder cleaning gun conform to the green, lean and automatic development process of modern enterprises.

Automatic powder cleaning system for mixed-line hub bolt holes and combined powder cleaning gun

A device for transferring a hub ground chain tray. An upper slider and a lower slider parallel to each other are arranged at the head end, a cylinder mounting plate is arranged below the upper and lower sliders, a cylinder is arranged below the cylinder mounting plate, a slider is arranged at the end of a piston rod of the cylinder, the left and right sides of the slider are provided with rotating pins, the two ends of the rotating pins can be installed in the strip through holes respectively in a sliding manner, and the two rotating pins are connected with the tail of the clamping jaw; the head of the clamping jaw is provided with jaw fingers, the jaw fingers are provided with the clamping blocks, and a transferrable tray device is arranged between the clamping blocks.

Device for transferring hub ground chain tray

Disclosed is a hub paint spraying equipment equipped with a spraying robot having a combined spray gun, comprising a control system, a wheel type recognition system, a brace recognition system, a paint supply device, a quick color changing device, spraying robot, combined spray gun, a cleaning system, a conveying chain and an accessory device. Combined spray gun installed at the end of spraying robot of system is formed by assembling a plurality of spray gun individuals, spraying process and parameter are automatically called by automatic recognition of wheel type recognition system, category of a colored paint is automatically changed, spraying parameter and robot spraying path program are called, and mixed-line intelligent spraying of a hub is realized, so that problems of low utilization rate of equipment due to consumption of a lot of time for replacing colored paint and excessive in-process caused by classification and temporary storage stacking are avoided.

Hub paint spraying equipment equipped with spraying robot having combined spray gun

The present application discloses an intelligent flexible hub powder spraying line and process. The intelligent flexible hub powder spraying line comprises a control system, a wheel type recognition system, a brace recognition system, a conveying chain, off-line carrying robots, a powder spraying isolation area, an oven, an on-line area, an off-line area and accessory equipment, wherein the conveying chain comprises a chain, braces and a driving mechanism. By applying a plurality of powder spraying units and the recognition systems, multiple kinds of powder can be simultaneously sprayed with different parameters.

Intelligent flexible hub powder spraying line and process

A self-adjusting robot clamping jaw for clamping a hub on a hub coating line to complete transfer can realize certain self-adjustment via rotation of an upper connecting plate around a rotating pin in the clamping process when the wear extents of clamping fingers are inconsistent, and can prevent the phenomena that the hub is clamped obliquely and even a hub brace is bent by lateral force. The clamping fingers made of a soft material can prevent damaging the surface coating and can be convenient to replace.
