Description

Technical Field

[0001] This utility model relates to the field of hardware parts inspection technology, specifically a bearing device for detecting surface defects in hardware parts. Background Technology

[0002] In the manufacturing process of hardware parts, surface defect detection is a crucial step in ensuring product quality. Surface defects not only affect the appearance of parts but can also seriously impact their performance and lifespan. Currently, common surface defect detection technologies for hardware parts include manual inspection, machine vision-based inspection, and non-destructive testing techniques.

[0003] In the process of inspecting surface defects in hardware parts, the support device, as a key component for supporting and fixing the parts, directly affects the inspection results. Most existing support devices have simple structures and limited functions, making it difficult to meet complex inspection requirements. For example, some support devices can only achieve horizontal placement of parts, failing to fix them in place. During inspection, parts may shift or wobble, affecting the accuracy and stability of the inspection. Furthermore, even when using clamps to hold hardware parts, existing clamps cannot adapt to hardware parts of different heights and lengths. When inspecting hardware parts of different heights or lengths, it is often necessary to readjust the clamps, which is time-consuming and labor-intensive. Therefore, there is an urgent need to improve the support device for inspecting surface defects in hardware parts to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a bearing device for detecting surface defects in hardware parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bearing device for detecting surface defects in hardware parts, comprising a worktable, four sets of support legs fixedly installed at the bottom of the worktable, a clamping assembly provided on the side of the worktable, and an adjustment assembly provided inside the worktable; the bearing device for detecting surface defects in hardware parts includes a clamping mechanism and an adjustment mechanism, the clamping mechanism including the worktable, a cylinder fixedly installed at the center of the worktable, a driving block fixedly installed at the top of the output end of the cylinder, two sets of limiting rods fixedly installed on the driving block, limiting edges movably installed at both ends of the limiting rods, the limiting rods movably installed in a driven block, and a limiting cavity cooperating with the limiting edges provided in the driven block.

[0006] Preferably, two sets of fixing rods are fixedly installed on the side of the driven block. A drive plate is movably installed on the fixing rod. The drive plate is "V" shaped, and the center of the drive plate is movably installed in a through groove provided in the fixture mounting seat through a fixing rod.

[0007] Preferably, the other end of the drive plate is movably mounted on the triangular plate via a rotating shaft, the lower end of the triangular plate is movably mounted on the limiting protrusion on the side of the clamp mounting seat via a rotating shaft, the upper end is movably mounted inside the connecting plate via a rotating shaft, and the other end of the connecting plate is movably mounted on the gripper via a rotating shaft.

[0008] Preferably, the gripper is "F" shaped, and the inner side of the gripper is movably mounted on the top limiting protrusion of the clamp mounting base via a rotating shaft. A top foot is movably mounted on the front end of the gripper, and an anti-slip rubber pad is fixedly mounted on the lower surface of the top foot.

[0009] Preferably, the adjustment mechanism includes a clamp mounting base and a worktable. A splicing arm is fixedly installed on the inner side of the clamp mounting base, and a limiting rod is fixedly installed at the front end of the splicing arm. A limiting groove is provided on the splicing arm, and the clamp mounting base on the same side is movably installed in the limiting groove through the limiting rod to achieve splicing.

[0010] Preferably, a slider is fixedly installed at the bottom of the fixture mounting base, and two sets of sliding grooves are movably provided in the worktable. The slider is movably installed in the sliding grooves, and the slider is movably installed at both ends of the screw through threads. The screw is a bidirectional screw with opposite threads at the front and rear ends, and the screws on the left and right sides are the same.

[0011] Preferably, a driven tooth is fixedly installed at the end of the screw, a motor mounting bracket is fixedly installed on the side of the worktable, a motor is fixedly installed on the motor mounting bracket, a drive tooth is fixedly installed on the output shaft of the motor, and the driven tooth and the drive tooth form a transmission through the drive tooth.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This bearing device for detecting surface defects in hardware parts has a clamping mechanism that uses a cylinder to drive a drive block downwards. A limiting rod engages with a limiting cavity within the driven block, and a linkage mechanism consisting of a "V"-shaped drive plate, a triangular plate, and a connecting plate drives the "F"-shaped gripper's front end to press against the part surface. The rotating top foot can accommodate hardware parts within a certain height range. The anti-slip rubber pad on its lower surface enhances clamping stability and prevents scratches on the part surface, effectively solving the problems of poor adaptability to part height and unstable clamping in existing technologies.

[0013] 2. This bearing device for surface defect detection of hardware parts has an adjustment mechanism that is driven by a motor to rotate the drive gear, which in turn drives the bidirectional screw to rotate via the driven gear. By utilizing the opposite threads at both ends of the screw and the threaded engagement of the slider, the slider causes the clamp mounting base to move in opposite directions within the slide groove. Simultaneously, the clamp mounting base on the same side can be spliced ​​with the limiting groove via the limiting rod two on the splicing arm. This allows for precise adjustment of the clamping length according to the length of the hardware part, effectively improving the applicability of the device to parts of different sizes and solving the problem of fixed clamping range and inability to flexibly adapt to the detection needs of parts of different lengths in existing bearing devices.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] Based on existing technologies, most support devices have simple structures and limited functions, making it difficult to meet complex testing requirements. Some support devices can only achieve horizontal placement of parts and cannot fix them in place. During the testing process, parts may shift or shake, affecting the accuracy and stability of the testing. Therefore, this device is equipped with a clamping mechanism. Please refer to [link / reference]. Figures 1-4 This utility model provides a technical solution: a bearing device for detecting surface defects in hardware parts, including a workbench 1, four sets of support legs 2 fixedly installed at the bottom of the workbench 1, a clamping assembly 3 provided on the side of the workbench 1, and an adjustment assembly 4 provided inside the workbench 1; the bearing device for detecting surface defects in hardware parts includes a clamping mechanism and an adjustment mechanism, the clamping mechanism includes the workbench 1, a cylinder 201 fixedly installed at the center of the workbench 1, a drive block 202 fixedly installed at the top of the output end of the cylinder 201, two sets of limit rods 203 fixedly installed on the drive block 202, limit edges 214 movably installed at both ends of the limit rods 203, and the limit rods 203 movably installed in the driven block 204, the driven block 204 having a limit cavity 215 that cooperates with the limit edge 214.

[0018] Two sets of fixing rods 205 are fixedly installed on the side of the driven block 204. A drive plate 206 is movably installed on the fixing rod 205. The drive plate 206 is "V" shaped. The center of the drive plate 206 is movably installed in the through groove 208 provided in the fixture mounting base 207 through the fixing rod 209.

[0019] The other end of the drive plate 206 is movably mounted on the triangular plate 210 via a pivot. The lower end of the triangular plate 210 is movably mounted on the limiting protrusion on the side of the clamp mounting base 207 via a pivot, and the upper end is movably mounted inside the connecting plate 211 via a pivot. The other end of the connecting plate 211 is movably mounted on the gripper 212 via a pivot.

[0020] The gripper 212 is F-shaped. The inner side of the gripper 212 is movably mounted on the top limiting protrusion of the clamp mounting base 207 via a rotating shaft. The front end of the gripper 212 is movably mounted with a top foot 213, and the lower surface of the top foot 213 is fixedly mounted with an anti-slip rubber pad.

[0021] When hardware parts need to be inspected, the parts are placed on the workbench 1, and the cylinder 201 is activated. The output end pushes the drive block 202 downward, causing the two sets of limit rods 203 to move downward synchronously. The limit edges 214 at both ends of the limit rods 203 slide within the limit cavities 215 of the driven block 204, ensuring that the drive block 202 moves vertically downward following the limit rods 203. The driven block 204 drives the "V"-shaped drive plate 206 to move through the fixing rod 205. The center of the drive plate 206 is fixed to the fixture mounting base 2 through the fixing rod 209. The drive plate 206 rotates within the through slot 208 of 07, and the other end of the drive plate 206 pushes the triangular plate 210 through the rotating shaft. The lower end of the triangular plate 210 is fixed on the limiting protrusion of the clamp mounting base 207, and the upper end pulls the connecting plate 211 through the rotating shaft. The connecting plate 211 drives the "F"-shaped gripper 212 to rotate around the limiting protrusion at the top of the clamp mounting base 207, so that the top foot 213 at the front end of the gripper 212 abuts against the surface of the part. The top foot 213 can rotate to adapt to parts of different heights. The anti-slip rubber pad on its lower surface enhances the clamping stability and prevents scratching the parts. Example

[0022] Based on Embodiment 1, when clamping and fixing hardware parts, existing fixtures cannot adapt to hardware parts of different heights and lengths. When inspecting hardware parts of different heights or lengths, it is often necessary to readjust the fixtures, which is time-consuming and laborious. Therefore, this device is equipped with an adjustment mechanism. Please refer to [link / reference]. Figures 4-6 This utility model provides a technical solution: a bearing device for detecting surface defects of hardware parts. The adjustment mechanism includes a clamp mounting base 207 and a worktable 1. A splicing arm 301 is fixedly installed on the inner side of the clamp mounting base 207. A limiting rod 302 is fixedly installed at the front end of the splicing arm 301. A limiting groove 303 is provided on the splicing arm 301. The clamp mounting base 207 on the same side is movably installed in the limiting groove 303 through the limiting rod 302 to achieve splicing.

[0023] A slider 304 is fixedly installed on the bottom of the mounting base 207. Two sets of sliding grooves 305 are movably provided in the worktable 1. The slider 304 is movably installed in the sliding grooves 305. The slider 304 is movably installed at both ends of the screw 306 by threads. The screw 306 is a bidirectional screw with opposite threads at the front and rear ends.

[0024] A driven tooth 307 is fixedly installed at the end of the screw 306. A motor mounting bracket 308 is fixedly installed on the side of the worktable 1. A motor 309 is fixedly installed on the motor mounting bracket 308. A drive tooth 310 is fixedly installed on the output shaft of the motor 309. The driven tooth 307 and the drive tooth 310 are connected by a transmission through the drive tooth 310.

[0025] When it is necessary to inspect hardware parts of different lengths, the motor 309 is started, and the drive gear 310 on the output shaft drives the driven gear 307 to rotate through the chain 311. The driven gear 307 is fixed to the end of the bidirectional screw 306. When the bidirectional screw 306 rotates, because the threads at both ends are opposite, the sliders 304 on both sides move towards or away from each other in the slide groove 305. The sliders 304 are fixedly connected to the bottom of the fixture mounting base 207, thereby driving the fixture mounting base 207 to move horizontally in the worktable 1. The fixture mounting base 207 on the same side is spliced ​​by inserting the limiting rod 302 on the splicing arm 301 into the limiting groove 303 of the other splicing arm 301. The clamping span can be adjusted according to the length of the parts to ensure stable clamping of parts of different lengths.
