Description

Technical Field

[0001] This utility model relates to the field of fixtures, and in particular to a transfer fixture for a wheel hub production robot. Background Technology

[0002] Currently, the wheel hub processing flow typically includes five processes: casting, spinning, heat treatment, machining, and painting. In actual production, in order to avoid human contamination and damage when the wheel hub enters the painting process and to ensure the consistency of the product's appearance, automated transfer equipment such as wheel hub transfer robots are mostly used to transfer the wheel hub to the painting process.

[0003] Some existing wheel hub transfer robots use grippers that support the wheel hub's sidewall with clamping blocks, utilizing significant friction to hold and transfer the hub. This method results in the wheel hub being subjected to compressive force on one side, causing slight deformation to the sidewall and affecting the hub's quality. To address this issue, we propose a wheel hub production robot transfer gripper. Utility Model Content

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] Reference Figures 1-8 The present invention provides a wheel hub production robot transfer fixture, which includes a body 100. Two sets of clamping units 200 for clamping wheel hubs are symmetrically arranged on the side wall of the body 100. A drive unit 300 for driving the clamping units 200 to clamp the wheel hubs is provided above each of the two sets of clamping units 200.

[0033] The clamping unit 200 includes a first clamping mechanism 202 and a second clamping mechanism 201. The first clamping mechanism 202 is used to support and clamp the inner wall of the wheel hub, and the second clamping mechanism 201 is used to clamp the outer wall of the wheel hub. By clamping the inner and outer sides of the wheel hub simultaneously, slight deformation caused by unilateral force on the wheel hub can be effectively avoided. At the same time, the clamping is more stable and safer during transportation. The first clamping mechanism 202 includes a first housing 203. The interior of the first housing 203 is provided with a threaded groove 2033. A first screw 500 is threadedly connected to the threaded groove 2033. One end of the first screw 500 is rotatably connected to a connecting block 2028, which facilitates the first clamping mechanism 202 to support the inner wall of the wheel hub. In addition, the first clamping mechanism 202 is supported and clamped by a threaded connection, which has a reliable self-locking function, which can effectively improve safety and prevent the first clamping mechanism 202 from automatically failing due to damage to the drive source, thereby preventing the wheel hub from falling off during clamping.

[0034] Three sets of first connecting rods 2027 are rotatably connected to the side wall of the connecting block 2028. One end of the three sets of first connecting rods 2027 is rotatably connected to a second connecting rod 2023. The lower end of the first housing 203 is fixedly connected to a chassis 2021. The lower end of the chassis 2021 is fixedly connected to a first bracket 2022. One end of the second connecting rod 2023 is rotatably connected to the first bracket 2022. The other end of the second connecting rod 2023 is provided with a clamping block groove 2024. A first clamping block 2026 is provided inside the clamping block groove 2024. A spring 2025 is fixedly connected inside the first clamping block 2026. One end of the spring 2025 is fixedly connected to the side wall of the clamping block groove 2024. The spring 2025 is used to buffer the first clamping block 2026 and the hub.

[0035] In use, the first screw 500 rotates towards the lower end of the first housing 203, causing the connecting block 2028 to move downward. The connecting block 2028 pushes the second connecting rod 2023 outward through the first connecting rod 2027. The second connecting rod 2023 drives the first clamping block 2026 to approach the inner wall of the wheel hub until it is completely pressed and adhered to the inner wall of the wheel hub. Due to the large friction between the first clamping block 2026 and the inner wall of the wheel hub, the first clamping block 2026 can clamp and transfer the wheel hub. Moreover, this clamping method can adapt to wheel hubs of various sizes.

[0036] The second clamping mechanism 201 includes a first slider 502 symmetrically fixedly connected to the side wall of the first screw 500. The second clamping mechanism 201 also includes a second screw 501. The interior of the second screw 501 is symmetrically provided with two sets of first slide grooves 5011. The first slider 502 is slidably disposed in the first slide groove 5011 to realize that the first screw 500 drives the second screw 501 to rotate without affecting the downward movement of the first screw 500 along the first slide groove 5011.

[0037] The first housing 203 has a second screw groove 2032 inside, and a second screw 501 is disposed in the second screw groove 2032. The second screw 501 can rotate in the second screw groove 2032. The side wall of the first housing 203 has two sets of second sliding grooves 2031 symmetrically provided. The outer wall of the second screw 501 is threadedly connected to a second slider 2016. The second slider 2016 can move up and down linearly on the rotating second screw 501. The side wall of the second slider 2016 is symmetrically fixedly connected to two sets of extrusion members 2015. The two sets of extrusion members 2015 are slidably disposed in the second sliding grooves 2031, so that the extrusion members 2015 can move up and down along the second sliding grooves 2031.

[0038] Two sets of second brackets 2013 are symmetrically fixedly connected to the side wall of the first housing 203. Both sets of second brackets 2013 are rotatably connected to a third bracket 2012. A torsion spring 2014 is provided at the connection between the third bracket 2012 and the second bracket 2013. A second clamping block 2011 is fixedly connected to one end of the third bracket 2012. The second clamping block 2011 clamps the outer side wall of the wheel hub by cooperating with the pressing member 2015. The torsion spring 2014 can make the second clamping block 2011 in the initial state in an inclined unfolded state, which is beneficial to clamping the wheel hub. A crossbeam 400 is fixedly connected between the first housing 203 and the body 100.

[0039] The drive unit 300 includes a second housing 301 fixedly connected to the upper end of the first housing 203. A motor 302 is provided inside the second housing 301. The output end of the motor 302 is fixedly connected to the first screw 500. The motor 302 and the second housing 301 are slidably connected to each other, which is used to cooperate with the motor 302 to drive the first screw 500 to rotate downward.

[0040] In use, when the wheel hub is directly below the clamping unit 200, the motor 302 is started to rotate, which drives the first screw 500 to rotate downward. The first screw 500 drives the first clamping mechanism 202 to support the inner wall of the wheel hub. At the same time, the first screw 500 drives the second screw 501 to rotate, causing the second slider 2016 to drive the extruder 2015 to move downward. The extruder 2015 extrudes the third bracket 2012, causing the third bracket 2012 to drive the second clamping block 2011 to deflect downward and clamp the outer wall of the wheel hub, thereby completing the clamping and transfer of the wheel hub. The clamping unit 200 is equipped with two sets, which can realize the clamping of the wheel hub on one side and the release of the wheel hub after transfer on the other side, which can improve work efficiency.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
