Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-11As shown, this utility model provides a workpiece inspection fixture, including a rotating device 100, two affixing devices 200, two lifting devices 300, and a robot 400. The two affixing devices 200 are symmetrically arranged above the rotating device 100. The affixing devices 200 are used for installing and positioning automotive parts. The rotating device 100 is used to drive the affixing devices 200 to rotate. The lifting devices 300 are used to drive the two affixing devices 200 to move up and down. The robotic arm of the robot 400 is equipped with a blue light scanner 401 for inspecting automotive parts 10. The blue light scanner 401 is used to scan and inspect automotive parts 10.

[0023] Robot 400 is a general robot in this technical field, and there are no specific limitations here.

[0024] The blue light scanner 401 is a general blue light scanner in this technical field, and there is no specific limitation here. The blue light scanner 401 is mounted on the robotic arm of the robot 400. The robotic arm can drive the blue light scanner 401 to move and rotate, so as to perform multi-angle and multi-range scanning and detection on the automotive parts 10.

[0025] The rotating device 100 includes a rotating platform 101, the projection of which can be rectangular, and the rotating platform 101 has a symmetrical structure. The rotating device 100 also includes a rotating base 102, on which a rotating motor 103 is provided. The rotating platform 101 is mounted on the rotating motor 103, and the rotating motor 103 is used to drive the rotating platform 101 to rotate.

[0026] The dotting device 200 includes a crossbeam 201, and vertical beams 202 are provided at both ends of the crossbeam 201. The connection method between the crossbeam 201 and the vertical beams 202 can be a fixed connection method commonly used in this technical field, such as bolt connection, welding, etc., and no specific limitation is made here.

[0027] The tops of the two vertical beams 202 are equipped with support and positioning frames, which are used to support and position workpieces, such as automotive parts 10. The shape and structure of the support and positioning frames are adapted to the shape and structure of automotive parts 10, enabling effective support and positioning of automotive parts 10.

[0028] In one embodiment of this application, the support positioning frame is detachably mounted on the top of the two vertical beams 202. This detachable mounting method is common in the technical field and is not specifically limited herein. The support positioning frame can be replaced with one of corresponding shapes to accommodate different workpiece shapes, thereby enabling scanning and detection of workpieces with different shapes.

[0029] Automotive part 10 may include a rear longitudinal beam, without specific limitations.

[0030] The support positioning frame includes a support column 209, which can support the rear longitudinal beam, so that the rear longitudinal beam can be stably and effectively fitted on the support positioning frame.

[0031] The support positioning frame includes clamps 210, which can clamp and fix the rear longitudinal beam, so that the rear longitudinal beam can be stably and effectively fitted on the support positioning frame.

[0032] The projection of the rotating platform 101 is rectangular, and two bonding devices 200 are symmetrically arranged on both sides of the rotating platform 101. Specifically, the crossbeams 201 of the two bonding devices 200 respectively abut against both sides of the rotating platform 101.

[0033] A first positioning component is provided between the crossbeam 201 and the rotating device 100. The first positioning component includes a first positioning groove 203 provided at the bottom of the crossbeam 201 and a first positioning pin 104 provided above the rotating platform 101. The first positioning pin 104 is engaged in the first positioning groove 203.

[0034] Specifically, a protruding beam mounting plate 204 is fixed on the beam 201. The first positioning groove 203 is a recessed groove at the bottom of the beam mounting plate 204, and the first positioning pin 104 protrudes from the rotating platform 101. The axes of the first positioning pin 104 and the first positioning groove 203 are both vertical. The first positioning pin 104 fits in the first positioning groove 203 and can limit the lateral movement of the affixing device 200, so that the affixing device 200 cannot move laterally, thereby allowing the rotating device 100 to drive the affixing device 200 to rotate.

[0035] The lifting device 300 includes a lifting cylinder 301, a connecting plate 302 on the lifting cylinder 301, a guide rod 303 fixed on the connecting plate 302, and a lifting plate 304 fixed on the top of the guide rod 303. The lifting cylinder 301 is used to drive the connecting plate 302, the guide rod 303 and the lifting plate 304 to move up and down synchronously.

[0036] There are two lifting devices 300, with two vertical beams 202 cooperating with each lifting device 300. A second positioning assembly is provided between the vertical beams 202 and the lifting devices 300. The second positioning assembly includes a second positioning groove 205 located at the bottom of the vertical beam 202 and a second positioning pin 305 located above the lifting plate 304. Specifically, a vertical beam mounting plate 208 is fixed to the bottom of the vertical beam 202. The second positioning groove 205 is a recessed groove located at the bottom of the vertical beam mounting plate 208, and the second positioning pin 305 protrudes above the lifting plate 304. The second positioning pin 305 engages within the second positioning groove 205. The axes of the second positioning pin 305 and the second positioning groove 205 are both vertical, which can laterally limit the contact device 200, preventing it from moving laterally. This allows the lifting device 300 to move the contact device 200 up and down.

[0037] There are two lifting devices 300, which are installed on both sides of a lifting base plate 307. The lifting base plate 307 is located below a rotating platform 101, which rotates above it. Two affixing devices 200 are symmetrically arranged on both sides of the rotating platform 101, which drives the two affixing devices 200 to rotate. When one affixing device 200 rotates to the detection position, the other affixing device 200 rotates to the loading / unloading position. While the automotive part 10 on one affixing device 200 is being detected, the automotive part 10 on the other affixing device 200 can be loaded / unloaded. In the detection position, the two vertical beams 202 of the affixing device 200 correspond precisely to the two lifting devices 300. The two lifting devices 300 can synchronously move the affixing device 200 up and down, allowing the automotive part 10 on the affixing device 200 to move upwards to the blue light scanner 401, where the blue light scanner 401 can scan and detect the automotive part 10.

[0038] After the scanning and inspection are completed, the lifting device 300 moves the affixing device 200 down to above the rotating platform 101, so that the first positioning pin 104 engages in the first positioning groove 203; the lifting plate 304 continues to move down until the second positioning pin 305 separates from the second positioning groove 205, and the lifting device 300 no longer limits the affixing device 200. Then the rotating device 100 drives the affixing device 200 to rotate, rotating the inspected automotive part 10 to the loading position for unloading; at the same time, the affixing device 200 and the automotive part 10 in the loading position can be rotated to the inspection position for scanning and inspection.

[0039] The crossbeam 201 is provided with a first abutment post 206, and the rotating platform 101 is provided with a second abutment post 105 corresponding to the first abutment post 206. Specifically, the first abutment post 206 protrudes from the crossbeam mounting plate 204, and the second abutment post 105 protrudes from the rotating platform 101. When the contact point device 200 is engaged with the rotating platform 100, and the first positioning pin 104 is engaged in the first positioning groove 203, the first abutment post 206 just abuts against the second abutment post 105, which can prevent the crossbeam 201 and the rotating platform 101 from directly contacting each other, thus protecting the crossbeam 201 and the rotating platform 101 from wear.

[0040] The bottom of the vertical beam 202 is provided with a third abutment post 207, and the lifting plate 304 is provided with a fourth abutment post 306 corresponding to the third abutment post 206. Specifically, the third abutment post 207 protrudes from the vertical beam mounting plate 208, and the third abutment post 206 protrudes from the lifting plate 304. When the contact point device 200 is engaged with the lifting plate 304 and the second positioning pin 305 is engaged with the second positioning groove 205, the third abutment post 206 and the fourth abutment post 306 just abut against each other, which can prevent the vertical beam 202 and the lifting plate 304 from directly contacting each other, and can protect the vertical beam 202 and the lifting plate 304 from wear.

[0041] In one embodiment of this application, the distance between the two vertical beams 202 is greater than the side length of the rotating platform 101, and the distance between the two lifting plates 304 is also greater than the side length of the rotating platform 101. When the rotating platform 101 drives a contact device 100 to rotate to the detection position, the vertical beam mounting plates 208 at the bottom of the two vertical beams 202 can correspond to the two lifting plates 304 respectively. The vertical beam mounting plates 208 are set lower than the horizontal beam mounting plates 204 and lower than the rotating platform 101. This avoids the vertical beam mounting plates 208 from obstructing the rotation of the rotating platform 101 and facilitates the corresponding cooperation between the vertical beam mounting plates 208 and the lifting plates 304.

[0042] In one embodiment of this application, the lifting plate 304 is located above the lifting base plate 307, and the lifting cylinder 301 and the connecting plate 302 are located below the lifting base plate 307. The lifting base plate 307 is provided with a clearance opening 308 for navigating the guide rod 303. The bottom of the lifting base plate 307 is provided with a guide groove 309, and the guide rod 303 extends upward from the guide groove 309 to the top of the lifting base plate 307.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
