Description

Technical Field

[0001] This utility model relates to the field of lead screw testing technology, specifically a multifunctional lead screw testing device. Background Technology

[0002] Ball screws are the most commonly used transmission components in machine tools and precision machinery. Their main function is to convert rotary motion into linear motion or torque into axial reciprocating force. They also feature high precision, reversibility, and high efficiency. Before being put into use, ball screws need to be tested by testing equipment.

[0003] Existing lead screw testing equipment requires adjusting the tightness of a positioning clamping mechanism to hold the lead screw in place during the testing of various lead screws. The testing module then measures lead screw performance data such as aging degree, torque, and repeatability. During testing, the fixed end of the lead screw applies pressure to the clamping and positioning module, potentially causing loosening or wear in the clamping area. Because the clamping area is stabilized through adjustment, it is more susceptible to damage. Increased damage frequency affects testing efficiency, and the clamping and positioning effect of the equipment also decreases after damage, impacting the accuracy of the lead screw testing data. Therefore, optimization and improvement are necessary. Utility Model Content

Replacement chucks suitable for different types of lead screws can be easily replaced. Moreover, the replacement chuck, in conjunction with the bearing seat, can stably position the lead screw, reduce wear, and ensure the efficiency and accuracy of the testing equipment.

[0016] During the testing of lead screws, it may be necessary to test the same lead screw multiple times, or to test multiple lead screws of the same type.

The slider 6 is slidably connected to the top of the linear guide rail 5. The position of the replacement chuck 11 is controlled by adjusting the position of the slider 6 at the top of the linear guide rail 5. A buffer pad 7 is connected to the top of the slider 6. The buffer pad 7 improves the stability when the mounting plate 8 and the slider 6 are locked together.

[0027] Specifically, such as Figure 2 As shown, a plug-in block 9 is fixedly connected to the bottom of one end of the mounting plate 8, and a positioning block 10 is fixedly connected to the top of the mounting plate 8. A plug rod 12 that engages with the plug-in block 9 is connected to the bottom of the replacement clamp 11. The plug rod 12 is inserted into the inner side of the plug-in block 9 for pre-positioning, and then fixed to the mounting plate 8 by connecting screws through the screw holes in the replacement clamp 11.

[0028] Specifically, such as Figure 3 As shown, an inner support plate 15 is fixedly connected to the inner side of the slide frame 13, a baffle 16 is slidably connected to one end of the inner side of the slide frame 13, an inner groove 14 is provided on the inner side of the slide frame 13 and slidably connected to the inner support plate 15, and grooves are provided at both ends of the inner side of the mounting plate 8, which can be snapped onto the outer side of the slide frame 13 for guiding movement, and moved to the end limit and fixed.

[0029] Specifically, such as Figure 3 As shown, an elastic connector 17 is fixedly connected to the inner side of the baffle 16, and a limit block 18 is fixedly connected to one end of the baffle 16. The inner side of the baffle 16 and the inner side of the inner support plate 15 are fixedly connected by the elastic connector 17, so that the baffle 16 can be buffered after contacting the mounting plate 8 until the limit block 18 abuts against the inner support plate 15 for limitation.

[0030] A positioning accuracy detection component is provided on one side of the linear guide 5. The positioning accuracy detection component includes a mounting bracket 19. A slotted threaded sleeve 20 is connected to the inner side of the mounting bracket 19, and a displacement sensor 23 is provided on the inner side of the slotted threaded sleeve 20. The positioning accuracy detection component is used to detect the repeatability of the lead screw.

[0031] Specifically, such as Figure 4 As shown, the mounting bracket 19 is fixedly installed on one side of the top of the support plate 1. A fastening nut 21 is threadedly connected to one side of the slotted screw sleeve 20. The slotted screw sleeve 20 is inserted into the inner hole of the mounting bracket 19. The outer side of the slotted screw sleeve 20 is provided with four slots to increase the size range of the items that can be inserted inside the slotted screw sleeve 20. After insertion, it is fastened by the threaded connection between the fastening nut 21 and the slotted screw sleeve 20.

[0032] Specifically, such as Figure 4 As shown, the inner side of the slotted threaded sleeve 20 is connected to the adhesive sleeve 22, and the displacement sensor 23 is connected to the inner side of the adhesive sleeve 22. The adhesive sleeve 22 is sleeved in the middle of the slotted threaded sleeve 20 and the displacement sensor 23, which can further improve the stability during installation.

[0033] In this embodiment: a sliding snap-fit ​​fixing is provided between the mounting plate 8 and the slider 6 to facilitate the removal of the mounting plate 8. The fixing of the mounting plate 8 and the replacement chuck 11 through the plug-in fixing limit also facilitates disassembly and assembly. Replacement chucks 11 adapted to different models of lead screws can be easily replaced. Moreover, the replacement chuck 11, in conjunction with the bearing seat 2, can stably position the lead screw and reduce wear. During the lead screw testing process, it may be necessary to test the same lead screw multiple times, or multiple tests may be performed on the same type of lead screw. To avoid repeated positioning position deviation of the lead screw, a displacement sensor 23 is set to detect and ensure that the position does not shift.

[0034] The specific steps of this solution are as follows: Before the ball screw is tested, it is necessary to adjust it according to the size of the ball screw. Unscrew the screws connecting the replacement chuck 11 and the mounting plate 8, then move the insert rod 12 out of the insertion block 9, and then replace the replacement chuck 11 that is compatible with the ball screw test. Alternatively, the mounting plate 8 can be moved out and replaced entirely by sliding adjustment between the mounting plate 8 and the slider 6. During replacement, the mounting plate 8 is adjusted by sliding on the slide frame 13, and then the baffle 16 is pressed. The baffle 16 is buffered and protected by the elastic connector 17. The inner limit block 18 contacts the inner support plate 15 for limitation, and then the screws are tightened. The ball screw is connected and fixed by passing through the mounting plate 8, buffer pad 7 and slider 6 in sequence. During the test, the ball screw is positioned between the replacement chuck 11 and the bearing seat 2 by sliding the slider 6 on the linear guide rail 5. Then the reduction motor 4 rotates and the torque sensor 3 is used for detection. During the test of the ball screw, it may be necessary to test the same ball screw multiple times. When testing the same type of ball screw multiple times, the position is detected by the fixed displacement sensor 23 with its end attached to the positioning block 10 to ensure that the test position of the same product does not deviate each time, thus improving the accuracy of data detection.
