Description

Technical Field

[0001] This utility model belongs to the field of testing device technology, specifically an adjustable lead screw testing module. Background Technology

[0002] In automated production equipment, the lead screw module is an essential component. Its main function is to drive the linear motion of components such as jigs and devices that require displacement. However, all industrial equipment has a service life, especially high-precision equipment. After the service life is reached, maintenance and replacement are required. Therefore, manufacturers need to provide maintenance recommendations. Thus, the lead screw module needs to be tested for life before the product leaves the factory to determine its service life. Since different lead screw modules have different positions, the position of the motor needs to be adjusted. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable lead screw test module to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please refer to Figure 1-3 ;

[0022] The test module described in this utility model aims to verify the service life of the lead screw module 4 and adapt to different models of lead screw modules. Specifically, it includes a machine base 1, on which a cross adjustment component 2 is installed, and a motor 3 is installed at the adjustment end of the cross adjustment component 2. The upper surface of the machine base 1 is provided with an operation position 11 for installing the lead screw module 4. The operation position 11 mainly provides an installation position for the lead screw module 4, and the output end 31 of the motor 3 faces the operation position 11.

[0023] During operation, first place the lead screw module 4 on the operating position 11 and close to the output end 31 of the motor 3, but do not fix it. Then, adjust the position of the motor 3 according to the actual height of one end of the lead screw module 4 using the appropriate adjustment component. After the adjustment is completed, fix the position of the motor 3 and fix the lead screw module 4. Finally, use the connecting coupling 5 to connect the end of the lead screw module 4 and the output end 31 of the motor 3. The end of the lead screw module 4 refers to its input end. Since there will be some error between the position of the output end 31 of the motor 3 and the end of the lead screw module 4, the coupling 5 can make up for these errors. Moreover, the coupling 5 used for different lead screw modules 4 will be slightly different and can be replaced at any time.

[0024] The test purpose is achieved by driving the reciprocating motion of the lead screw module 4 through the forward and reverse rotation of the motor 3. At the same time, the position of the motor 3 can be adjusted by using the cross adjustment module to adapt to different models of lead screw modules 4, making it more convenient to use and expanding its application range.

[0025] After numerous reciprocating motions, the lead screw module 4 will wear out, affecting its normal use. Therefore, the motor 3 can be stopped after 10,000 to 100,000 reciprocating motions by setting the controller, and the wear condition of the lead screw module 4 can be observed to determine its lifespan. It should be noted that the lead screw module 4 tested should include parts such as the lead screw, nut, housing, bearing seat, and moving plate, to ensure that the nut reciprocates along the lead screw in a straight line when the lead screw rotates.

[0026] It should be noted that this test module should include the basic functions of the controller to control the speed, number of forward and reverse rotations, and counting of the motor, which are not related to the improvements in this application, and will not be described in detail here.

[0027] One embodiment of the cross-shaped adjustment assembly 2 of this utility model specifically includes a fixed base 21. The fixed base 21 is laterally provided with a first sliding pair 22 and a first adjusting member. Both the first adjusting member and the first sliding pair 22 are connected to a first movable plate 24. A first clamp 25 cooperating with the first sliding pair 22 is installed on the first movable plate 24. A second sliding pair 26 and a second adjusting member are longitudinally provided on the first movable plate 24. Both the second adjusting member and the second sliding pair 26 are connected to a second movable plate 28. A second clamp 29 cooperating with the second sliding pair 26 is installed on the second movable plate 28. In the initial state, the first clamp 25 and the second clamp 29 are fixed laterally and longitudinally, respectively. When adjustment is required, the first clamp 25 and the second clamp 29 can be released individually or simultaneously. Since the second movable plate 28 is restricted by the second adjusting member, it will not fall. Then, the first adjusting member and the second adjusting member are used to adjust the first movable plate 24 and the second movable plate 28, respectively. After completion, the first clamp 25 and the second clamp 29 are used to lock them to prevent the motor 3 from deviating during the test.

[0028] Preferably, the first adjusting member includes a lead screw assembly 231 mounted on a fixed base 21. Of course, a bearing housing or other accessories for mounting the lead screw assembly 231 are mounted on the fixed base 21. The moving end of the lead screw assembly 231 is connected to the first movable plate 24, and the end of the lead screw assembly 231 is provided with a rocker arm 232. When the first clamp 25 is released, the lead screw assembly 231 is rotated by the rocker arm 232, thereby driving the first movable plate 24, the second movable plate 28, and the motor 3 to move laterally for adjustment. After this is completed, the first clamp 25 is used to lock the position. The second adjusting member is fixed to the first fixed plate 271 at the upper end of the first movable plate 24. An adjusting screw 272 is rotatably connected to the fixed plate 271. The adjusting screw 272 is threadedly connected to the second fixed plate 273. The second fixed plate 273 is fixed to the upper end of the second movable plate 28. When it is necessary to adjust the longitudinal position, first release the lock of the second clamp 29. Since it is tightened by the adjusting screw 272 at this time, the second movable plate 28 will not fall but will stay in the current position. By using an external tool, such as a hex wrench, to rotate the adjusting screw 272, the second movable plate 28 can be adjusted longitudinally. In this embodiment, whether it is horizontal or vertical adjustment, a threaded adjustment method is used, which can adjust the position more precisely.

[0029] In this embodiment of the utility model, since the outer shells of different models of lead screw modules 4 are different, a number of fixing holes 12 are provided on the operation position 11 so that the installation positions of different lead screw modules 4 can be fixed by screws or other fasteners passing through the fixing holes 12.

[0030] In addition, there are usually specially customized lead screw modules 4 for customer requirements, which are different from the standard ones. Therefore, before testing, a counterweight (not shown) is installed on the moving part of the lead screw module 4. The mass of the counterweight is equivalent to the load of the lead screw module 4 in the actual production process. During the test, the counterweight moves back and forth to simulate the actual use scenario.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
