Description

Technical Field

[0001] This utility model relates to the field of lamp cover inspection tools, and in particular to an automotive lamp cover inspection tool. Background Technology

[0002] An automotive lamp cover inspection fixture is a specialized inspection tool used to ensure the quality and dimensional accuracy of lamp covers during the automotive manufacturing process. This fixture is an important tool for quality control of automotive parts and is of great significance for ensuring the safety performance, appearance quality, and service life of automotive lamps.

[0003] Most automotive lamp cover inspection tools use a method of applying a certain speed to an impact head and letting it hit the surface of the lamp cover. The damage to the lamp cover surface is then observed for judgment. In this process, the direction in which the impact head hits the lamp cover is fixed, which cannot effectively simulate impacts from different directions. This has certain limitations and may lead to inaccurate test results, reducing the practicality of the inspection tool.

[0004] Therefore, those skilled in the art have provided an automotive lamp cover inspection tool to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automotive lamp cover inspection tool. The tool uses a dual-axis motor to drive a first roller, which in turn drives a belt to a second roller, causing the second roller to rotate. Simultaneously, the rotation of the second roller drives a gear fixedly connected to one end of the gear. As the gear rotates, a toothed plate meshing with it on one side of its outer wall moves laterally. This movement of the toothed plate causes the extension sleeve and impact head, located on its lower end face, to move. The impact head, constrained by a sliding bar, moves within a slide rail, which is controlled by a first electric telescopic rod for raising and lowering. When impact testing of the lamp cover is required, the extension sleeve and impact head move left and right within a range driven by the toothed plate. Simultaneously, the raising and lowering of the slide rail causes the extension sleeve to shorten and lengthen, ultimately allowing the impact head to flexibly choose its impact position according to the shape and specifications of the automotive lamp cover, resulting in more accurate test results and improved practicality of the inspection tool.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automotive lamp cover inspection tool, comprising an impact mechanism, a clamping mechanism, and a controller. The upper end face of the clamping mechanism is provided with the impact mechanism, and one side end face of the clamping mechanism is provided with the controller. The impact mechanism includes two supports, each with a first electric telescopic rod disposed in its inner center. Each of the two supports has a pulley rotatably connected to its upper inner surface. A toothed plate is slidably connected to one side of the outer wall of each pulley. A support plate is provided at the upper end of each of the two supports. The upper end face of the support plate... The unit is equipped with a dual-axis motor. The output ends of the dual-axis motors are fixedly connected to first rollers. A belt is fitted on the middle of the outer wall of each of the two first rollers. A second roller is fitted on one side of the inner wall of each of the two belts. A gear is provided at one end of each of the two second rollers. A ball bearing is fixedly connected to one end of the outer wall of each of the two second rollers. An extension sleeve is provided at the middle of the lower end face of the toothed plate. An impact head is provided at the lower end of the extension sleeve. Slide bars are provided on both sides of the outer wall of the impact head. A slide rail is provided at one end of the output end of each of the two first electric telescopic rods.

[0007] Through the above technical solution, the inspection fixture uses a controller to control a dual-axis motor to drive the first roller to rotate, which in turn causes the belt on the first roller to drive the second roller to rotate. Simultaneously, the rotation of the second roller drives the gear fixedly connected to one end to rotate. As the gear rotates, a toothed plate meshing with it on one side of its outer wall moves laterally. This movement of the toothed plate causes the extension sleeve and impact head on its lower end face to move. The impact head moves within a slide rail under the constraint of a sliding bar. The slide rail is controlled by a first electric telescopic rod to raise and lower. When impact testing of the lamp cover is required, the extension sleeve and impact head move left and right within a range driven by the toothed plate. Simultaneously, the raising and lowering of the slide rail causes the extension sleeve to shorten and extend, ultimately allowing the impact head to flexibly select its position for impact according to the shape and specifications of the automotive lamp cover, resulting in more accurate test results and improved practicality of the inspection fixture.

[0008] Furthermore, the clamping mechanism includes a worktable, on both sides of the upper interior of the worktable are two second electric telescopic rods, and a fixed frame is provided at one end of the output end of each pair of second electric telescopic rods. A third electric telescopic rod is provided on both sides of the upper end face of the two fixed frames, and a connecting block is provided at one end of the output end of each pair of third electric telescopic rods. Multiple spring telescopic rods are provided on one side end face of the two connecting blocks, and a rubber abutment is provided at one end of the multiple spring telescopic rods.

[0009] Through the above technical solution, the inspection fixture, controlled by the controller according to the shape and size of the lamp cover, controls two sets of second electric telescopic rods to drive the fixed frame and the third electric telescopic rod on the fixed frame to move closer to the center of the upper surface of the workbench. During the approach process, the spring telescopic rod and rubber abutment fixedly connected to the output end of the two sets of third electric telescopic rods can stably and tightly hold the lamp cover to prevent it from shifting during the inspection process. This achieves flexible and stable clamping and fixing of the automotive lamp cover, improving the practicality of the inspection fixture.

[0010] Furthermore, both of the brackets are rotatably connected to the upper interior of each bracket;

[0011] Through the above technical solution, this setting enables the blocking roller to maintain its balance in a timely manner if the toothed plate tilts during movement.

[0012] Furthermore, ball bearings are fixedly connected to both sides of the lower end face of the support plate, and one end of each of the two second rollers passes through the ball bearings and is fixedly connected to a gear;

[0013] Through the above technical solution, this setting allows the gear to rotate along with the rotation of the second roller, and the ball bearing is used to make the gear rotation smoother and more stable.

[0014] Furthermore, a toothed plate is meshed with one side of the outer wall of the gear, and the length of the toothed plate is twice that of the support plate;

[0015] Through the above technical solution, this setting enables the toothed plate to move a sufficient distance under the drive of the gear, thereby allowing the impact head to strike in multiple directions.

[0016] Furthermore, the impact head penetrates the inner center of the slide rail, and slide bars are slidably connected to both sides of the outer wall of the slide rail;

[0017] Through the above technical solution, this setting allows the impact head to slide more smoothly within the slide rail and to rise and fall with the slide rail.

[0018] Furthermore, a receiving block is provided at the lower end of the interior of the workbench, and a servo motor is provided at the center of the upper surface of the receiving block;

[0019] Through the above technical solution, the receiving block can provide support for the servo motor, which is an important power source for the subsequent rotating parts.

[0020] Furthermore, the output end of the servo motor passes through the upper interior of the workbench and is fixedly connected to a rotary table, the lower end of which is rotatably connected to the upper interior of the workbench.

[0021] Through the above technical solution, this setting enables the servo motor to drive the rotary table to rotate on the worktable, and adjust the orientation of the lamp cover to be inspected in a timely manner, saving manpower.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model proposes an automotive lamp cover inspection tool. The tool is controlled by a controller to drive a dual-axis motor to rotate a first roller, which in turn causes a belt mounted on the first roller to drive a second roller to rotate. As the second roller rotates, it drives a gear fixedly connected to one end of the second roller to rotate. When the gear rotates, a toothed plate meshing with it on one side of its outer wall moves laterally. The movement of the toothed plate causes the extension sleeve and impact head mounted on its lower end face to move. The impact head moves in a slide rail under the constraint of a sliding bar. The slide rail is controlled by a first electric telescopic rod to achieve lifting and lowering. When impact testing of the lamp cover is required, the extension sleeve and impact head move within a left-right range under the drive of the toothed plate. At the same time, the lifting and lowering of the slide rail causes the extension sleeve to shorten and extend, ultimately allowing the impact head to flexibly select the direction for impact according to the shape and specifications of the automotive lamp cover, making the test results more accurate and improving the practicality of the inspection tool.

[0024] 2. The present invention proposes an automotive lamp cover inspection fixture. The fixture uses a controller to control two sets of second electric telescopic rods according to the shape and size of the lamp cover, driving the fixed frame and the third electric telescopic rod on the fixed frame to move the automotive lamp cover to be inspected towards the center of the upper surface of the workbench. During the approach process, the spring telescopic rod and the rubber abutment plate fixedly connected to the output end of the two sets of third electric telescopic rods can stably and tightly abut the lamp cover to prevent the lamp cover from shifting during the inspection process. This achieves flexible and stable clamping and fixing of the automotive lamp cover, improving the practicality of the inspection fixture. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Reference Figure 1-3 One specific embodiment provided by this utility model:

[0034] An automotive lamp cover inspection tool includes an impact mechanism 1, a clamping mechanism 2, and a controller 3. The impact mechanism 1 is mounted on the upper end face of the clamping mechanism 2, and the controller 3 is mounted on one side end face of the clamping mechanism 2. The impact mechanism 1 includes two supports 101, each with a first electric telescopic rod 102 mounted in the center of its interior. A pulley 103 is rotatably connected to the upper interior of each of the two supports 101. A toothed plate 104 is slidably connected to one side of the outer wall of each pulley 103. A support plate 106 is mounted on the upper end of each of the two supports 101. A dual-axis motor 107 is installed in the middle. The output ends of both motors 107 are fixedly connected to first rollers 108. A belt 109 is fitted around the middle of the outer wall of each of the two first rollers 108. A second roller 110 is fitted around one side of the inner wall of each of the two belts 109. A gear 111 is installed at one end of each of the two second rollers 110. A ball bearing 112 is fixedly connected to one end of the outer wall of each of the two second rollers 110. An extension sleeve 113 is installed in the middle of the lower end face of the toothed plate 104. An impact head 114 is installed at the lower end of the extension sleeve 113. The impact head 114... Both sides of the outer wall are provided with sliding rods 115. One end of the output of the two first electric telescopic rods 102 is provided with a slide rail 116. The inspection fixture, controlled by the controller 3, drives the dual-axis motor 107 to rotate the first roller 108, thereby causing the belt 109 mounted on it to transmit power to the second roller 110, causing it to rotate. Simultaneously, the rotation of the second roller 110 drives the gear 111 fixedly connected to one end to rotate. When the gear 111 rotates, the toothed plate 104 meshing with it on one side of the outer wall moves laterally. The movement of the toothed plate 104 causes the extension sleeve 113 on its lower end face and... The impact head 114 moves within the slide rail 116 under the constraint of the slide bar 115. The slide rail 116 is controlled by the first electric telescopic rod 102 to raise and lower. When impact testing of the lamp cover is required, the extension sleeve 113 and the impact head 114 move left and right under the drive of the toothed plate 104. At the same time, the raising and lowering of the slide rail 116 causes the extension sleeve 113 to shorten and extend, ultimately allowing the impact head 114 to flexibly select the direction for impact according to the shape and specifications of the car lamp cover, making the test results more accurate and improving the practicality of the inspection tool.

[0035] Reference Figure 3-5The clamping mechanism 2 includes a workbench 201. Two second electric telescopic rods 202 are arranged on both sides of the upper end of the workbench 201. A fixing frame 203 is provided at one end of the output end of each pair of second electric telescopic rods 202. A third electric telescopic rod 204 is arranged on both sides of the upper surface of each of the two fixing frames 203. A connecting block 205 is provided at one end of the output end of each pair of third electric telescopic rods 204. Multiple spring telescopic rods 206 are provided on one side of each connecting block 205. A rubber abutment 207 is provided at one end of each spring telescopic rod 206. The inspection tool passes through... The controller 3 controls two sets of second electric telescopic rods 202 according to the shape and size of the lamp cover, which drive the fixed frame 203 and the third electric telescopic rod 204 fixed on the fixed frame 203 to move the car lamp cover to be inspected closer to the center of the upper surface of the worktable 201. During the approach process, the spring telescopic rod 206 and the rubber abutment 207 fixedly connected to the output end of the two sets of third electric telescopic rods 204 can stably and tightly abut the lamp cover to prevent the lamp cover from shifting during the inspection process. This achieves flexible and stable clamping and fixing of the car lamp cover, improving the practicality of the inspection tool.

[0036] Both brackets 101 have a blocking roller 105 rotatably connected to their upper interior. This arrangement ensures that if the toothed plate 104 tilts during movement, the blocking roller 105 can maintain its balance in time.

[0037] Ball bearings 112 are fixedly connected to both sides of the lower end face of the support plate 106. One end of each of the two second rollers 110 passes through the ball bearings 112 and is fixedly connected to a gear 111. This arrangement allows the gear 111 to rotate with the rotation of the second rollers 110. The ball bearings 112 are used to make the rotation of the gear 111 smoother and more stable.

[0038] A toothed plate 104 is meshed with one side of the outer wall of the gear 111. The length of the toothed plate 104 is twice that of the support plate 106. This arrangement allows the toothed plate 104 to move a sufficient distance under the drive of the gear 111, so that the impact head 114 can impact in multiple directions.

[0039] The impact head 114 penetrates the center of the slide rail 116. Slide rods 115 are slidably connected to both sides of the outer wall of the slide rail 116. This arrangement allows the impact head 114 to slide more smoothly within the slide rail 116 and to rise and fall with the slide rail 116.

[0040] The lower end of the worktable 201 is provided with a support block 208, and the upper surface of the support block 208 is provided with a servo motor 209. The support block 208 can provide support for the servo motor 209, which is an important power source for the subsequent rotating parts.

[0041] The output end of the servo motor 209 passes through the upper part of the workbench 201 and is fixedly connected to the rotary table 210. The lower end of the rotary table 210 is rotatably connected to the upper part of the workbench 201. This arrangement enables the servo motor 209 to drive the rotary table 210 to rotate on the workbench 201, so as to adjust the orientation of the lamp cover to be inspected in a timely manner and save manpower.

[0042] Working principle: The inspection fixture, controlled by the controller 3, drives the dual-axis motor 107 to rotate the first roller 108, which in turn causes the belt 109 mounted on it to transmit power to the second roller 110, causing it to rotate as well. Simultaneously, the rotation of the second roller 110 drives the gear 111 fixedly connected to one end to rotate. As the gear 111 rotates, the toothed plate 104 meshing with it on one side of its outer wall moves laterally. This movement of the toothed plate 104 causes the extension sleeve 113 and the impact head 114 mounted on its lower end face to move. The impact head 114, constrained by the sliding bar 115, moves within the slide rail 116, which is raised and lowered by the first electric telescopic rod 102. When impact testing of the lampshade is required, the extension sleeve 113 and the impact head 114 move within the toothed plate... The plate 104 moves within a range of left and right, while the slide rail 116 rises and falls, causing the extension sleeve 113 to shorten and extend, ultimately allowing the impact head 114 to flexibly select the direction for impact according to the shape and specifications of the car lamp cover. Before inspection, the inspection tool controls the two sets of second electric telescopic rods 202 according to the shape and size of the lamp cover, driving the fixed frame 203 and the third electric telescopic rod 204 fixedly connected to the output end of the two sets of third electric telescopic rods 204 to place the car lamp cover to be inspected closer to the center of the upper surface of the worktable 201. During the approach process, the spring telescopic rod 206 and the rubber abutment 207 fixedly connected to the output end of the two sets of third electric telescopic rods 204 can stably and tightly abut the lamp cover to prevent the lamp cover from shifting during the inspection process.
