Description

Technical Field

[0001] This application relates to the field of machinery, and in particular to a positioning fixture for high-precision inspection of parts. Background Technology

[0002] In industrial manufacturing, high-precision inspection of components is a crucial step in ensuring product quality and performance. Accurate inspection can promptly detect dimensional deviations, shape defects, and surface quality issues that occur during the production process, thereby ensuring that the assembled product meets design requirements and improving product reliability and stability. Positioning fixtures, as important auxiliary tools in the component inspection process, primarily function to accurately and stably fix components in specific positions so that inspection devices can precisely measure and evaluate them.

[0003] When existing positioning fixtures are used, the angle and position of the parts are usually locked after they are fixed, which cannot be flexibly changed with the detection device, thus failing to achieve the ideal positioning effect. Multi-directional detection of parts requires manual disassembly and reassembly to change the angle, which increases the complexity of the entire detection process. Utility Model Content

[0004] In order to achieve flexible angle adjustment of the positioning fixture, this application provides a positioning fixture for high-precision inspection of parts.

[0005] This application provides a positioning fixture for high-precision inspection of parts, which adopts the following technical solution:

[0006] The device includes a fixed base that is fixedly installed on top of a positioning seat. A rotating disk is rotatably installed above the fixed base. Two support columns are fixedly installed on the upper surface of the rotating disk. A positioning block is slidably sleeved on the outer side of the support columns. A fixed clamping plate is fixedly installed on one side of the positioning block. A component is placed on top of the fixed clamping plate. A movable clamping plate that matches the fixed clamping plate and clamps the component is movably installed on one side of the positioning block.

[0007] By adopting the above technical solution, the rotation angle of the parts can be adjusted by rotating the rotating disk, and the height of the parts can be adjusted along the support column by the positioning block. This allows the height position of the parts to be adjusted, thereby meeting the needs of the detection device and making it convenient and quick to adjust the angle of the parts to achieve multi-directional detection.

[0008] Preferably, a first motor is fixedly mounted on the upper surface of the positioning seat, a gear is mounted on the output end of the first motor, and an annular rack is fixedly mounted on the lower outer side of the rotating disk, with the gear meshing with the annular rack.

[0009] By adopting the above technical solution, the first motor can drive the gear to rotate the ring rack and the rotating disk, which can adjust the rotation angle of the parts, making it convenient to rotate the detection angle of the parts, greatly improving the detection efficiency and shortening the detection cycle.

[0010] Preferably, a second motor is fixedly installed on the top of the rotating disk, and a threaded rod is installed on the output end of the second motor, which is threadedly connected to the positioning block.

[0011] By adopting the above technical solution, the second motor can drive the threaded rod to adjust the height of the positioning block along the support column, thereby allowing the height of the parts to be adjusted according to the needs of the detection device, without the need for repeated manual disassembly and assembly.

[0012] Preferably, an electric telescopic rod is fixedly installed on the other side of the positioning block, a connecting rod is installed at the output end of the electric telescopic rod, and movable columns are fixedly installed at both ends of the connecting rod.

[0013] By adopting the above technical solution, it is convenient to move the connecting rod and the movable column by means of the electric telescopic rod, so that the movable column can drive the movable clamping plate to clamp and fix the parts placed on the top of the fixed clamping plate, ensuring the stability of the parts and facilitating the inspection operation.

[0014] Preferably, one end of the movable column is fixedly installed with the movable clamping plate, and the movable column passes through the positioning block and is slidably sleeved with the positioning block.

[0015] By adopting the above technical solution, it is easy to support and fix the moving clamping plate, so that the moving clamping plate can move horizontally stably, and the moving clamping plate can stably clamp and fix the parts, which facilitates the testing operation of the testing device.

[0016] Preferably, some of the movable clamping plates are fixedly equipped with first protective pads, and one side of the fixed clamping plate is fixedly equipped with a second protective pad.

[0017] By adopting the above technical solution, it is easy to protect the clamped and fixed parts, avoid damage caused by bumps and knocks, and provide reliable assurance for product quality.

[0018] Preferably, the upper surface of the fixed clamping plate has two strip-shaped slots, and the strip-shaped slots correspond to the positions of the movable clamping plate.

[0019] By adopting the above technical solution, it is convenient for the moving clamping plate to move in coordination with the fixed clamping plate to perform clamping and inspection operations on parts of different thicknesses.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The first motor drives the gear to rotate the ring rack and the rotating disk, which can adjust the rotation angle of the parts. The second motor drives the threaded rod to adjust the height of the positioning block along the support column, which can adjust the height position of the parts. This can meet the needs of the detection device, make it convenient and quick to adjust the angle of the parts, realize multi-directional detection, eliminate the need for repeated manual disassembly and assembly, and greatly improve the detection efficiency.

[0022] 2. By using an electric telescopic rod to move the connecting rod and the movable column, the movable column drives the movable clamping plate to clamp and fix the parts placed on top of the fixed clamping plate. This ensures the stability of the parts as the inspection angle changes, facilitates the inspection operation, and provides reliable assurance for product quality. Attached Figure Description

[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0029] This application discloses a positioning fixture for high-precision inspection of parts, including a fixed seat 2 fixedly installed on the top of a positioning seat 1, a rotating disk 3 rotatably installed above the fixed seat 2, two support columns 7 fixedly installed on the upper surface of the rotating disk 3, a positioning block 10 slidably sleeved on the outer side of the support columns 7, a fixed clamping plate 17 fixedly installed on one side of the positioning block 10, a part 11 placed on the fixed clamping plate 17, and a movable clamping plate 15 that matches the fixed clamping plate 17 and clamps the part 11 movably installed on one side of the positioning block 10.

[0030] By setting up a rotating disk 3, component 11, and support column 7, the rotation of the rotating disk 3 allows for the adjustment of the rotation angle of component 11. In conjunction with the positioning block 10 adjusting the height along the support column 7, the height position of component 11 can be adjusted. This allows for convenient and quick adjustment of the angle of component 11 to meet the needs of the detection device, enabling multi-directional detection.

[0031] Reference Figure 2 , Figure 4 A first motor 5 is fixedly installed on the upper surface of the positioning seat 1. A gear 6 is installed at the output end of the first motor 5. A ring rack 4 is fixedly installed on the lower outer side of the rotating disk 3. The gear 6 meshes with the ring rack 4.

[0032] By setting up a first motor 5 and a gear 6, the first motor 5 drives the gear 6 to rotate the ring rack 4 and the rotating disk 3, which can adjust the rotation angle of the component 11, making it easier to rotate the detection angle of the component 11 and greatly improving the detection efficiency.

[0033] Reference Figure 1 , Figure 4 A second motor 8 is fixedly installed on the top of the rotating disk 3. A threaded rod 9 is installed on the output end of the second motor 8, and the threaded rod 9 is threadedly connected to the positioning block 10.

[0034] By setting a second motor 8 and a threaded rod 9, the second motor 8 can drive the threaded rod 9 to adjust the height of the positioning block 10 along the support column 7, thereby adjusting the height of the component 11. This allows the height of the component 11 to be adjusted according to the needs of the testing device, eliminating the need for repeated manual disassembly and assembly and shortening the testing cycle.

[0035] Reference Figure 2 An electric telescopic rod 12 is fixedly installed on the other side of the positioning block 10. A connecting rod 13 is installed at the output end of the electric telescopic rod 12. Movable columns 14 are fixedly installed at both ends of the connecting rod 13.

[0036] By setting up an electric telescopic rod 12, a connecting rod 13, and a movable column 14, it is convenient to move the connecting rod 13 and the movable column 14 through the electric telescopic rod 12, so that the movable column 14 can drive the movable clamping plate 15 to clamp and fix the component 11 placed on the top of the fixed clamping plate 17, ensuring the stability of the component 11 and facilitating the inspection operation.

[0037] Reference Figure 2 One end of the movable column 14 is fixedly installed with the movable clamping plate 15, and the movable column 14 passes through the positioning block 10 and is slidably sleeved with the positioning block 10.

[0038] By setting the movable column 14, it is easy to support and fix the movable clamping plate 15, so that the movable clamping plate 15 can move horizontally stably and can stably clamp and fix the part 11, which is convenient for the testing device to perform testing operations.

[0039] Reference Figure 2 , Figure 3 The movable clamping plate 15 is fixedly equipped with a first protective pad 16, and the fixed clamping plate 17 is fixedly equipped with a second protective pad 18 on one side; the upper surface of the fixed clamping plate 17 has two strip-shaped slots 19, which correspond to the positions of the movable clamping plate 15.

[0040] By setting the first protective pad 16 and the second protective pad 18, the clamped and fixed parts 11 can be protected to avoid damage caused by bumps and collisions, thus providing a reliable guarantee for product quality.

[0041] The implementation principle of a positioning fixture for high-precision inspection of parts in this application embodiment is as follows: First, the part 11 is placed on the surface of the second protective pad 18 on the top of the fixed clamping plate 17. Then, the electric telescopic rod 12 extends to drive the connecting rod 13 and the movable column 14 to move, thereby driving the movable clamping plate 15 to clamp and fix the part 11. Then, the first motor 5 drives the gear 6 to rotate, and the gear 6 drives the ring rack 4 and the rotating disk 3 to rotate, so that the rotating disk 3 drives the part 11 above to rotate and adjust the angle. The second motor 8 drives the threaded rod 9 to rotate, and the threaded rod 9 drives the positioning block 10 to adjust the height along the support column 7, thereby adjusting the height of the part 11 to meet the needs of the inspection device and adjusting the inspection position of the part 11 for inspection.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
