Description

Technical Field

[0001] This utility model relates to the field of lead screw and nut transmission technology, specifically to a tooling for detecting the runout of the lead screw and nut assembly. Background Technology

[0002] The lead screw and nut drive is a core mechanism that converts rotary motion into linear motion by the meshing of the lead screw and the internal thread of the nut. It is widely used in machine tools, automated equipment and other scenarios with high positioning accuracy requirements. The detection of the runout of the lead screw and nut is a key link to ensure the accuracy of the transmission mechanism. By measuring the radial runout, axial movement and other offsets when the two move relative to each other, the smoothness of transmission and positioning accuracy are ensured. The existing swerve measurement tooling has been found to require high levels of professional skills from operators, and inconsistent operating techniques can lead to poor accuracy of the test results. It is difficult to complete the test quickly and conveniently in scenarios such as on-site maintenance and small-batch production. Its practicality and universality are insufficient, and it cannot efficiently meet the demand for both convenient and accurate testing. Therefore, it needs to be improved. Therefore, it is necessary to invent a tooling for detecting the runout of the lead screw and nut. Summary of the Invention

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] See attached document Figure 1 -Appendix Figure 7 The present invention provides a tooling for detecting the runout of a lead screw and nut, including a fixed base 1 and a guide rail 2 connected to the front side of the fixed base 1. A dial indicator 3 is provided on the front side of the guide rail 2, and a clamping component is provided between the dial indicator 3 and the fixed base 1 for clamping and supporting the dial indicator 3. The fixed base 1 has a T-shaped groove 4, and a support component is provided in the T-shaped groove 4, which is used to support the lead screw to be tested; like Figure 7 As shown, during use, the lead screw to be tested can be supported by the support component, and the dial indicator 3 can be clamped and supported by the clamping component. When clamping and supporting, the bottom end of the dial indicator 3 is in contact with the left end of the lead screw. Then, pressure is applied to the end of the lead screw to cause it to wobble. The data displayed by the dial indicator 3 is the wobble of the lead screw and nut. In this way, the wobble can be detected. Moreover, this tooling is simple and requires low professional skills. It can not only accurately measure the wobble of the lead screw and nut, but also the detection method is simple, practical and easy to operate. Specifically, the clamping component includes two slide grooves 5, both of which are opened on the fixed base 1. The two slide grooves 5 are located at the top and bottom of the guide rail 2, respectively. An operating groove 6 is opened on the rear side of the two slide grooves 5. The clamping component also includes a dial indicator base 7, which is slidably set outside the guide rail 2. A dial indicator 3 passes through the insertion hole on the dial indicator base 7. The dial indicator base 7 is provided with an adjusting bolt 1 8, which is used to adjust the clamping force of the dial indicator base 7 on the dial indicator 3. The dial indicator base 7 is provided with two adjusting bolts 2 9, which pass through the two slide grooves 5 respectively, and the two adjusting bolts 2 9 are used to increase the stability between the dial indicator base 7 and the fixed base 1. When in use, insert dial indicator 3 into the socket on the base 7, and then turn the adjusting screw 8 to gradually reduce the diameter of the socket. In this way, the base 7 can clamp dial indicator 3. Note that when inserting dial indicator 3 into the socket, the bottom end of dial indicator 3 should be in contact with the left end of the lead screw. When testing the lead screw, the length of the lead screw is different. Therefore, it is necessary to move the position of the gauge base 7 and the dial indicator 3 horizontally. When moving horizontally, loosen the two adjusting bolts 29. Then the gauge base 7 can be moved horizontally, so that the dial indicator 3 can be moved to the appropriate position. Finally, tighten the two adjusting bolts 29. Specifically, the support component includes two vertically distributed clamping blocks 10. Each clamping block 10 has a T-shaped block integrally formed on its rear side, and both T-shaped blocks are slidably disposed in the T-shaped groove 4. A lead screw seat 11 is provided between the two clamping blocks 10, and a threaded groove 12 is opened on the inner wall of one end of the lead screw seat 11. Two through holes are opened between one of the clamping blocks 10 and the fixed seat 1, and a pin 13 is slidably inserted into each of the two through holes. Two adjusting bolts 14 are provided between the two clamping blocks 10, and the two adjusting bolts 14 are used to adjust the clamping force of the two clamping blocks 10 on the lead screw seat 11. When in use, insert the T-shaped blocks on the two clamping blocks 10 into the T-shaped grooves 4 in sequence. When the through hole on the lower clamping block 10 is flush with the through hole on the fixed seat 1, insert the two pins 13 into the two through holes. This will support the two clamping blocks 10. Then place the lead screw tube seat 11 between the two clamping blocks 10. Then tighten the two adjusting bolts 14 so that the two clamping blocks 10 can clamp the lead screw tube seat 11. Since a threaded groove 12 is provided on the inner wall of the right end of the lead screw tube seat 11, the lead screw can be inserted into the lead screw tube seat 11 during use, and then the lead screw can be screwed into the threaded groove 12 by turning the lead screw, thus achieving support for the lead screw. This tool needs to be fixed when in use, for example, it will be fixed on a table. For this purpose, two U-shaped frames 15 are fixedly connected to the back of the fixed base 1. Rubber blocks 16 are fixedly connected to the bottom inner wall of both U-shaped frames 15, and fastening bolts 17 are embedded in the top of both U-shaped frames 15. When in use, align the two U-shaped brackets 15 with the desktop and insert them. Then, tighten the two fastening bolts 17 so that the bottom of the fastening bolts 17 is in close contact with the top of the desktop. This will fix the fixture on the desktop.

[0020] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model shall fall within the scope of protection claimed by this utility model.
