Description

Technical Field

[0001] The invention relates to the field of detection and inspection, in particular to a fixed screw three-seat concentric reverse device and a method for detecting the relative position accuracy of a slide mechanism by using the device. Background Art

[0002] In the industrial production process, it is often necessary to use a sliding table mechanism. There is a traditional sliding table mechanism (such as Figure 1 , Figure 2 As shown), it includes a lead screw driven by a motor, a nut seat connected to the lead screw is connected to a nut bracket, and the top of the nut bracket is connected to the slide, and the slide is slidably connected to the slide rail. When the motor drives the lead screw to rotate, the lead screw and nut transmission pair will convert the rotational motion of the lead screw into linear motion of the slide, that is, the slide will slide relative to the slide rail; in the slide mechanism, in order to ensure the smooth movement between the slide and the slide rail, the two need to have a certain relative position relationship, and at the same time, it is also necessary to ensure the coaxiality relationship between the output shaft of the motor and the nut seat (that is, the mounting hole on the nut bracket that matches the nut seat). In the actual production process, if there is an error in the relative position relationship of the above two pairs of mechanisms, it may cause the slide mechanism to bear additional stress during operation, affecting the working life and reliability of the slide. Therefore, a method or device that can solve the above problems is now needed. Summary of the invention

[0003] The present invention aims to solve the above-mentioned deficiencies in the prior art and proposes a fixed screw three-seat concentric reverse device which has a simple structure, ingenious design, and reasonable layout, and can quickly, conveniently and accurately detect whether the relative position accuracy between the slide seat and the nut bracket in the slide mechanism meets the requirements. A method for detection using this device is also proposed.

[0004] The technical solution of the present invention is: a fixed screw three-seat concentric reverse device, characterized in that: the device includes a correction component 1, a detection component 2 and a standard inspection rod 13,

[0005] The correction assembly 1 includes a positioning frame 3 with an L-shaped cross section, and connecting plates 4 are connected to both ends of the positioning frame 3. The end of the connecting plate 4 is connected to one end of a positioning plate 6 through a bolt 5. The bolt 5 is connected to a long hole 7 opened on the positioning plate 6. At the same time, a V-shaped positioning portion 8 is also provided at the other end of the positioning plate 6.

[0006] The detection assembly 2 comprises a standard tire block 9 , on which a magnetic base 10 is adsorbed, on which a meter stand 11 is arranged, and on which a micrometer 12 is arranged.

[0007] A method for testing using the above-mentioned fixed screw three-seat concentric reverse device, characterized in that the method is carried out in the following steps in sequence:

[0008] a. Insert the standard inspection rod 13 into the motor seat 14, and buckle the positioning frame 3 on the correction component 1 onto the guide rail 15. After the V-shaped positioning parts 8 on the two positioning plates 6 are in contact with the standard inspection rod 13, use the bolts 5 to fix the positioning plate 6 and the connecting plate 4 to complete the adjustment operation of the correction component 1.

[0009] b. Remove the calibration component 1 from the guide rail 15 and place it upside down on the operating platform 16. Take the standard inspection rod 13 out of the motor seat 14 and place it on the V-shaped positioning portion 8 at the top of the two positioning plates 6. Place the detection component 2 on the calibration component 1, specifically, place the standard tire block 9 on the positioning frame 3, adjust the meter frame 11, let the probe of the micrometer 12 contact the surface of the standard inspection rod 13, find the highest point, and record the data, completing the operation of calibrating the detection component 2 through the calibration component 1.

[0010] c. Then remove the calibrated detection component 2 from the calibration component 1, and place the slide 17 to be tested upside down on the operating platform 16, ensuring that the nut bracket 18 connected to the slide 17 is in an upward position, remove the standard inspection rod 13 from the motor base 14, and insert it into the auxiliary sleeve 19 pre-installed in the mounting hole on the nut bracket 18, use the probe of the micrometer 12 to measure the surface of the standard inspection rod 13, observe the value corresponding to the highest point of the standard inspection rod 13 at this time, and compare it with the data recorded in step b. If the difference between the two meets the requirements, it means that the relative position relationship between the nut bracket 18 and the slide 17 meets the requirements. If the difference between the two does not meet the requirements, adjust the relative position between the nut bracket 18 and the slide 17 until the difference in the measurement results meets the requirements, which means that the relative position relationship between the nut bracket 18 and the slide 17 meets the requirements.

[0011] Compared with the prior art, the present invention has the following advantages:

It includes three parts: a correction component, a detection component and a standard inspection rod. These three parts are operated according to certain processes and steps, and can quickly and conveniently detect the relative position relationship between the slide and the nut bracket connected to the slide. If the relative position relationship between the two exceeds the allowable range, it can be adjusted by adjusting the nut bracket, and then tested again after adjustment until the test is qualified. This device, combined with the corresponding detection method, can ensure the relative position accuracy of the key dimensions in the slide structure, thereby ensuring the quality of the slide and extending its service life. In addition, the manufacturing process of the device is simple and the manufacturing cost is low. Therefore, it can be said that it has many advantages and is particularly suitable for promotion and application in this field. Its market prospects are very broad. BRIEF DESCRIPTION OF THE DRAWINGS

Figures 1 to 6 As shown: a fixed screw three-seat concentric reverse device, which includes a correction component 1, a detection component 2 and a standard inspection rod 13.

[0020] The correction assembly 1 includes a positioning frame 3 with an L-shaped cross section, and connecting plates 4 are connected to both ends of the positioning frame 3. The end of the connecting plate 4 is connected to one end of a positioning plate 6 through a bolt 5. The bolt 5 is connected to a long hole 7 opened on the positioning plate 6. At the same time, a V-shaped positioning portion 8 is also provided at the other end of the positioning plate 6.

[0021] The detection assembly 2 comprises a standard tire block 9 , on which a magnetic base 10 is adsorbed, on which a meter stand 11 is arranged, and on which a micrometer 12 is arranged.

[0022] When using the fixed screw three-seat concentric reverse device as described above for testing, follow the following steps in order:

[0023] First, insert the standard inspection rod 13 into the motor seat 14, and buckle the positioning frame 3 on the correction component 1 onto the guide rail 15, that is, use the positioning frame 3 with an L-shaped cross-section and the guide rail 15 to position the correction component 1. At this time, the bolt 5 is not tightened, and the positioning plate 6 can move relative to the connecting plate 4. After the V-shaped positioning parts 8 on the two positioning plates 6 are in contact with the standard inspection rod 13, the positioning plate 6 and the connecting plate 4 are fixed with the bolt 5 to complete the adjustment operation of the correction component 1 (such as Figure 5 ),

[0024] Then, the calibration component 1 is removed from the guide rail 15, turned over 180°, and placed upside down on the operating platform 16. The standard inspection rod 13 is taken out from the motor seat 14 and placed on the V-shaped positioning portion 8 at the top of the two positioning plates 6. The detection component 2 is placed on the calibration component 1, specifically, the standard tire block 9 is placed on the positioning frame 3, and the meter frame 11 is adjusted to allow the probe of the micrometer 12 to contact the surface of the standard inspection rod 13, find the highest point (that is, the highest busbar on the standard inspection rod 13 in this state), and record the data, completing the operation of calibrating the detection component 2 through the calibration component 1 (such as Figure 6 ),

[0025] Finally, remove the calibrated detection component 2 from the calibration component 1, and place the slide 17 to be tested upside down on the operating platform 16, ensuring that the nut bracket 18 connected to the slide 17 is in an upward position, remove the standard inspection rod 13 from the motor base 14, and insert it into the auxiliary sleeve 19 pre-installed in the mounting hole on the nut bracket 18 (the auxiliary sleeve here is used to simulate the nut sleeve), use the probe of the micrometer 12 to measure the surface of the standard inspection rod 13, observe the value corresponding to the highest point of the standard inspection rod 13 at this time (that is, the highest busbar on the standard inspection rod 13 in this state), and compare it with the data recorded in step b. If the difference between the two meets the requirements, it means that the relative position relationship between the nut bracket 18 and the slide 17 meets the requirements. If the difference between the two does not meet the requirements, adjust the relative position between the nut bracket 18 and the slide 17 until the difference in the measurement results meets the requirements. At this time, it means that the relative position relationship between the nut bracket 18 and the slide 17 meets the requirements.
