Abstract
Description
Technical Field
[0001] This utility model relates to the field of gauge testing technology, specifically a gauge wear detection device. Background Technology
[0002] A gauge is a specialized inspection device used to measure and evaluate the dimensional quality of parts. It is designed and manufactured according to product drawings and relevant technical requirements. It can quickly and accurately determine whether parts meet design standards. Gauges are mainly used for batch inspection of parts in the production process. By comparing with standard templates or data, they can accurately measure parameters such as dimensional deviations, shape errors, and positional accuracy of parts.
[0003] However, existing technologies still have the following problems:
[0004] First, most existing fixture wear detection devices are not convenient for precise adjustment of the position of the detection structure. They mostly use manual operation or simple motor drive, which makes it difficult to accurately position the detection components and easily produces large deviations during the detection process. They cannot meet the detection requirements of high-precision fixtures, cannot flexibly adjust the position for fixtures of different sizes and shapes, and limit the detection range and application scenarios. Some special fixtures cannot be effectively detected.
[0005] Secondly, existing fixture wear detection devices are usually not stable enough in fixing the fixtures. Some use simple clamps or manual fixing methods, which makes the fixtures prone to displacement or shaking, seriously affecting the accuracy of the test results. When the detection device is in a vibrating environment or the test process is long, the possibility of fixture displacement increases, leading to fluctuations in the test data.
[0006] To address the aforementioned problems, the inventors have proposed a tool wear detection device to solve these issues. Utility Model Content
[0007] To address the problems of inconvenient and unstable fixture fixation in gauge wear detection devices, this invention aims to provide a gauge wear detection device.

[0018] 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.
[0019] Example: Figure 1-3 As shown, this utility model provides a tool wear detection device, including a base plate 1, an upper plate 2 and a bracket 4 fixedly mounted on the upper surface of the base plate 1, vertical blocks 21 symmetrically fixedly mounted on the upper surface of the upper plate 2, a sliding block 24 slidably mounted between two corresponding vertical blocks 21, a limiting post 26 fixedly mounted between two corresponding vertical blocks 21, and the limiting post 26 passing through the corresponding sliding block 24, wherein a lead screw 22 is rotatably mounted between two corresponding vertical blocks 21, and a servo motor 23 is fixedly mounted on the outer side of one of the vertical blocks 21, the output end of the servo motor 23 passing through the vertical block 21 and fixedly connected to the lead screw 22, the outer surface of the lead screw 22 and the sliding block 24 are connected to the sliding block 24. The moving block 24 is threadedly connected, and a moving plate 25 is fixedly provided on the upper surface of the moving block 24. When it is necessary to adjust the position of the placement plate 31 and the detection component 3 in the horizontal direction, the servo motor 23 is started. The output end of the servo motor 23 drives the lead screw 22 to rotate. Since the lead screw 22 is threadedly connected to one of the moving blocks 24, and the moving block 24 is restricted by the limiting post 26 to slide only in the direction of the limiting post 26, the rotation of the lead screw 22 will cause the moving block 24 to move linearly along the limiting post 26. The movement of the moving block 24 drives the moving plate 25 fixedly connected to it to move, thereby realizing the movement of the placement plate 31 and the detection component 3 in the horizontal direction.
[0020] A through slot 27 is formed on the upper surface of the upper plate 2. A placement plate 31 is slidably mounted on the upper side of the movable plate 25, and a detection component 3 is mounted on the upper side of the placement plate 31. The detection component 3 uses a laser displacement sensor (Jifeng Electronics LK-N050), whose working principle is based on triangulation. The laser beam emitted by the laser emitter irradiates the surface of the gauge, and the reflected light is received by the receiver. A guide rail 33 is symmetrically fixed on the upper surface of the movable plate 25, and an electric slider 34 is slidably mounted on the upper surface of the guide rail 33. The upper surface of the electric slider 34 is fixedly connected to the movable plate 25. A placement tube 32 is fixedly mounted on the lower surface of the placement plate 31. The detection component 3 is inserted into the placement tube 32, and the detection head of the detection component 3 penetrates the placement tube 32 and extends below the placement tube 32. The placement tube 32 is made of high-strength aluminum alloy. Not only is it lightweight, but it also has good rigidity. The inner wall of the placement tube 32 is equipped with an anti-slip rubber bushing. When the detection component 3 is inserted into the placement tube 32, the rubber bushing can increase the friction and ensure that the detection component 3 is stably installed, avoiding shaking or displacement during the detection process. The upper surface of the moving plate 25 is provided with a groove for use with the detection component 3 and the placement tube 32. The electric slider 34 slides on the guide rail 33, which can further fine-tune the position of the placement plate 31 on the moving plate 25, so that the detection component 3 can accurately reach the position to be detected. After the placement plate 31 and the detection component 3 reach the appropriate detection position through the above-mentioned movement control, the detection head of the detection component 3 penetrates the placement tube 32 and extends to the bottom of the placement tube 32 to detect the wear of the gauge fixed on the carrier plate 41 and feed back the detection data.
[0021] A carrier plate 41 is provided on the upper side of the bracket 4. Support rods 47 are symmetrically connected to the upper surface of the bracket 4 and the carrier plate 41 by bolts. Clamping plates 42 are symmetrically slidably provided on the upper surface of the carrier plate 41. Limiting blocks 48 are symmetrically fixed on the lower surface of the clamping plates 42 and are locked onto the carrier plate 41. Gears 44 are rotatably provided on the upper surface of the bracket 4. A DC motor 43 is fixedly provided on the lower surface of the carrier plate 41 and its output end is fixedly connected to the gear 44. Gear plates 45 are symmetrically meshed on the outer surface of the gears 44. Slide strips 49 are fixedly provided on the lower surface of the gear plates 45 and are locked onto the bracket 4. Vertical rods 46 are fixedly provided on the upper surface of the gear plates 45 and their upper ends are fixedly connected to the corresponding clamping plates 42. The upper surface of the carrier plate 41... The surface is symmetrically provided with sliding grooves 410, and the vertical rod 46 is locked in the corresponding sliding groove 410. When it is necessary to fix the fixture, the fixture is placed on the carrier plate 41 and the DC motor 43 is started. The output end of the DC motor 43 drives the gear 44 to rotate. The gear 44 meshes with the symmetrically arranged toothed plates 45. Since the toothed plates 45 are locked on the bracket 4 through the slide bar 49, they can only move in a straight line. Therefore, the rotation of the gear 44 will cause the two toothed plates 45 to move in opposite directions or in a straight line. The movement of the toothed plates 45 is transmitted to the clamping plate 42 through the vertical rod 46, so that the clamping plate 42 slides in opposite directions or in opposite directions on the carrier plate 41. When the two clamping plates 42 slide in opposite directions, the fixture can be clamped and fixed on the carrier plate 41, which is convenient for the detection component 3 to detect the wear of the fixture.
[0022] Working principle: When it is necessary to adjust the horizontal position of the placement plate 31 and the detection component 3, the servo motor 23 is started. The output end of the servo motor 23 drives the lead screw 22 to rotate. Since the lead screw 22 is threadedly connected to one of the moving blocks 24, and the moving block 24 is restricted by the limiting post 26 to slide only along the direction of the limiting post 26, the rotation of the lead screw 22 will cause the moving block 24 to move linearly along the limiting post 26. The movement of the moving block 24 drives the moving plate 25 fixedly connected to it to move, thereby realizing the horizontal movement of the placement plate 31 and the detection component 3.
[0023] The electric slider 34 slides on the guide rail 33, which can further fine-tune the position of the placement plate 31 on the moving plate 25, so that the detection component 3 can accurately reach the position to be detected.
[0024] When it is necessary to fix the fixture, place the fixture on the carrier plate 41 and start the DC motor 43. The output end of the DC motor 43 drives the gear 44 to rotate. The gear 44 meshes with the symmetrically arranged toothed plates 45. Since the toothed plates 45 are clamped on the bracket 4 by the slide bar 49, they can only move in a straight line. Therefore, the rotation of the gear 44 will cause the two toothed plates 45 to move in a straight line towards or away from each other. The movement of the toothed plates 45 is transmitted to the clamping plate 42 through the vertical rod 46, so that the clamping plate 42 slides in a straight line towards or away from each other on the carrier plate 41. When the two clamping plates 42 slide towards each other, the fixture can be clamped and fixed on the carrier plate 41, which makes it convenient for the detection component 3 to detect the wear of the fixture.
[0025] After the placement plate 31 and the detection component 3 reach the appropriate detection position through the above-mentioned movement control, the detection head of the detection component 3 penetrates through the placement tube 32 and extends below the placement tube 32 to detect the wear of the gauge fixed on the carrier plate 41 and feeds back the detection data.
[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
