Description

Technical Field

[0001] The utility model relates to the technical field of dimension detection, and specifically relates to a rapid detection device for the dimensions of precision parts. Background Technique

[0002] The actual dimension refers to the dimension of a certain hole or shaft obtained through measurement. Since there is still measurement error during measurement, the actual dimension is not the true value of the dimension. Due to the existence of machining errors, the actual dimensions of the parts processed according to the same drawing requirements are often different. Even for different positions and different directions of the same workpiece, the actual dimensions are often different. Therefore, the actual dimension is the measured value at a certain position on the actual part.

[0003] After retrieval, it is found that a Chinese patent with the application number CN 216621013 U. discloses a device for rapidly detecting the dimensions of parts, including a bottom plate. A column is connected to the side wall of one side of the bottom plate. A T-shaped sliding groove one is opened in the bottom plate. A T-shaped sliding block one is slidably arranged in the T-shaped sliding groove one. A moving clamping plate is connected to the upper wall of the T-shaped sliding block one. A fixed clamping plate matched with the moving clamping plate is arranged on the bottom plate. A T-shaped sliding groove two is opened in the column. A T-shaped sliding block two is slidably arranged in the T-shaped sliding groove two. A lifting plate is connected to the side wall of the T-shaped sliding block two. A cylinder is connected to the upper wall of the lifting plate. The piston rod end of the cylinder passes through the lifting plate and is connected with a laser sensor. A connecting rod is connected to the bottom wall of the lifting plate. The other end of the connecting rod is connected with a pressing plate. A driving mechanism one for driving the T-shaped sliding block one is arranged on the bottom plate. A driving mechanism two for driving the T-shaped sliding block two is arranged on the column. The advantages of the utility model compared with the prior art are as follows: the measurement accuracy is improved, and the movement of the part during measurement is prevented from affecting the measurement result.

[0004] The above-mentioned utility model has the following problems:

[0005] 1. In the above application, only one of the length, width and height of the part can be detected in a single detection operation. If re-measurement is required, the part needs to be adjusted and operated again, which greatly increases the workload of the staff and reduces the measurement efficiency.

[0006] 2. In the above application, a laser sensor is used to measure the dimensions. And during long-term use, the laser sensor may age and be damaged, resulting in poor measurement accuracy and affecting subsequent work.

[0007] Therefore, those skilled in the art have provided a rapid detection device for the dimensions of precision parts to solve the problems raised in the above background technique. Content of the Utility Model

[0008] The purpose of the utility model is to provide a rapid detection device for the dimensions of precision parts to solve the problems raised in the above background technique.

[0009] To achieve the above object, the present utility model provides the following technical solutions:

[0014] As a further step of the present utility model: The driving gear meshes with the first rack, and the driving gear meshes with the second rack.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

The second scale 14 is arranged parallel to the first lead screw 9 and the slide rod 12. A moving plate 15 is fixedly connected to the upper ends of the first threaded sleeve 10 and the slide sleeve 13. A clamping mechanism is arranged on the upper end of the moving plate 15; when the first servo motor 11 is started, the first servo motor 11 drives the first lead screw 9 to rotate. According to the characteristics of threaded connection, the first lead screw 9 drives the first threaded sleeve 10 at its upper end to move at the upper end of the stroke of the first lead screw 9, thereby driving the moving plate 15 fixedly connected to the upper end of the first threaded sleeve 10 to move until it reaches one end of the second scale 14. The length of the component can be detected through the second scale 14; due to the provision of an adjustment mechanism, by using the first lead screw 9 and the first threaded sleeve 10, stable movement and position locking can be provided, avoiding measurement errors caused by instability during movement. Just start the motor, and the system can automatically complete the adjustment of the moving plate 15 to the position of the second scale 14, and accurately measure the length through the second scale 14. The operation is relatively simple and fast, and the position of the moving plate 15 can be adjusted arbitrarily, making the clamping space of the clamping mechanism larger and facilitating the clamping work.

[0029] Embodiment 3

[0030] Refer to Figures 1-4, this embodiment is based on the previous embodiment. The difference from the previous embodiment is that a driving gear 16 is movably clamped at the exact center inside the moving plate 15. A second servo motor 21 is fixedly connected to the bottom end of the driving gear 16. One end of the driving gear 16 is movably connected to a first rack 17, and the other end of the driving gear 16 is movably connected to a second rack 18. One end of the first rack 17 away from the driving gear 16 is fixedly connected to a first clamping plate 19, and one end of the second rack 18 away from the driving gear 16 is fixedly connected to a second clamping plate 20. Sliders 22 are fixedly connected to the bottom ends of both the second clamping plate 20 and the first clamping plate 19. A clamping groove 25 is formed inside the moving plate 15. A pair of symmetrically arranged clamping slots 23 are formed inside the clamping groove 25. The clamping slots 23 and the clamping blocks 22 are correspondingly arranged, and the clamping slots 23 are slidably connected to the clamping blocks 22. A second lead screw 26 is movably clamped inside the second clamping plate 20. A second thread sleeve 27 is threadedly connected to the outer sidewall of the second lead screw 26. A third vernier caliper 28 is fixedly connected to the upper end of the second thread sleeve 27. The third vernier caliper 28 is slidably connected to the second clamping plate 20. One end of the second lead screw 26 is fixedly connected to a hand wheel 29. Limiting plates 24 are fixedly connected to the exact center positions of the sidewalls of both the second clamping plate 20 and the first clamping plate 19 close to the driving gear 16. The driving gear 16 meshes with the first rack 17, and the driving gear 16 meshes with the second rack 18. Place the component to be detected in the clamping groove 25 inside the moving plate 15. Then start the second servo motor 21. The second servo motor 21 drives the driving gear 16 to rotate. And the driving gear 16 meshes with the first rack 17, and the driving gear 16 meshes with the second rack 18. Thus, the first rack 17 and the second rack 18 can be simultaneously driven to move towards one end of the driving gear 16. Since the first rack 17 and the second rack 18 are driven by the same gear, the moving speeds of the first rack 17 and the second rack 18 are the same. Thus, the component to be detected can be centered and clamped by the first clamping plate 19 and the second clamping plate 20 fixedly connected to the upper ends of the first rack 17 and the second rack 18. At the same time, the clamping blocks 22 at the bottom ends of the first clamping plate 19 and the second clamping plate 20 assist in sliding in the clamping slots 23 inside the clamping groove 25. When turning the hand wheel 29, the hand wheel 29 drives the second lead screw 26 to rotate. According to the threading connection characteristics, the second lead screw 26 drives the upper second thread sleeve 27 to move at the upper end of the travel of the second lead screw 26. Thus, the third vernier caliper 28 fixedly connected to the upper end of the second thread sleeve 27 is driven to move until the third vernier caliper 28 fits the clamped component. The height of the component is detected by the third vernier caliper 28;Due to the clamping mechanism provided, the utility model is applicable to parts of various shapes and sizes. Only by adjusting the clamping and measuring positions can it meet the requirements of different workpieces. Through the structural design of the second lead screw 26, high-precision movement and position control can be achieved, enabling the third scale caliper 28 to move to the edge of the clamped part, ensuring accurate measurement of the height of the clamped part. And by rotating the handwheel 29, the operator can easily control the rotation of the second lead screw 26. Then, according to the meshing between the driving gear 16 and the first rack 17 and the second rack 18, the part is centered and clamped by the first clamping plate 19 and the second clamping plate 20, facilitating subsequent measurement work.
