[0002] During the motor manufacturing process, motor testing equipment is required to test the motor performance of the manufactured motor (including motor speed data and other test items). However, when the current testing equipment is testing the motor, the motor to be tested is placed on the test bench of the electrical equipment, and the position and angle of the motor need to be manually adjusted to facilitate viewing and moving the motor during testing, which greatly reduces the testing efficiency.

[0003] In the prior art, the Chinese patent with announcement number CN 213069103 U discloses a micro motor detection mechanism. Although, through the coordinated use of the clamping mechanism, double-headed motor, screw rod, threaded block, support column, clamping block and rubber plate, the micro motor is fixedly clamped, so as to facilitate its detection. When in use, the double-headed motor is turned on, and the screw rods at both ends are driven to rotate by the operation of the double-headed motor, thereby driving the threaded holes on the screw rod to approach each other, so that the two clamping blocks are close to each other, and the micro motor in the middle is fixedly clamped to make it stable. When the threaded block moves, the slider moves in the slide groove at the same time, and the movement of the entire support column is driven more smoothly, thereby improving the stability of the clamping. However, the clamping mechanism cannot adjust the height and angle position of the motor to be tested. The function of the motor detection equipment is greatly reduced, and the efficiency of motor detection is also reduced. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0023] like Figure 1-5 The adjustable clamping mechanism of the motor detection device shown includes a table top 1, on which a lifting adjustment component and an angle adjustment component are provided, the lifting adjustment component is provided with a rotating component, and the angle adjustment component is provided with a clamping component.

[0024] The lifting and lowering adjustment components respectively include a first supporting leg 15, a second supporting leg 16, a ball screw 2 and a first stepper motor 3. The first supporting leg 15 and the second supporting leg 16 are both slidably connected to the table board 1. The first supporting leg 15 and the second supporting leg 16 pass through the table board 1 and are slidably connected to the table board 1. The through hole is equivalent to a slide rail to constrain the movement trajectory of the first supporting leg 15 and the second supporting leg 16. The lower end of the ball screw 2 is fixedly connected to the table board 1, the output shaft end of the first stepper motor 3 is transmission-connected to the ball screw 2, and the sliding block of the ball screw 2 is fixedly connected to the second supporting leg 16.

[0025] The first stepper motor 3 is used to drive the ball screw 2, and the sliding block of the ball screw 2 drives the second support leg 16 to slide up and down during the up and down movement. The second support leg 16 and the parts fixedly connected to the second support leg 16 can move up and down as a whole, that is, the height position can be adjusted.

[0026] The angle adjustment components include an annular body 5, a rotating body 6, a handle 12, and a clamping strip 13 disposed on the handle 12. The annular body 5 is rotatably connected to one end of the rotating body 6. The handle 12 is fixedly disposed on a side wall of one end of the rotating body 6. A plurality of clamping grooves 14 are provided on the edge of the end of the annular body 5 close to the handle 12. The clamping strip 13 and the clamping groove 14 can be limitedly clamped. The annular body 5 is fixedly disposed at the upper ends of the first support leg 15 and the second support leg 16.

[0027] Specifically, the rotating body 6 can rotate in the annular body 5, and at the same time, through the cooperation of the clamping strip 13 and the clamping groove 14, the rotating body 6 that rotates a certain angle can be fixed, so that the rotating body 6 is in a fixed static state, thereby realizing the angle position adjustment. When in use, the handle 12 is held by hand, and the rotating body 6 is rotated to rotate the rotating body 6 in the annular body 5 to adjust the angle position; after adjusting to an appropriate angle by rotation, the clamping strip 13 on the handle 12 is extended, and at this time, the lower end of the clamping strip 13 is hinged with the handle and the lower end part is embedded in the handle 12. When the clamping strip 13 on the handle 12 is extended, the clamping strip 13 and the handle 12 are vertical, and the non-hinged end of the clamping strip 13 can be clamped in the clamping groove 14, and the clamping strip 13 is clamped in the clamping groove 14, and the clamping groove 14 limits the clamping strip, and the clamping strip 13 and the handle hinged therewith, and the rotating body 6 fixedly connected to the handle cannot move, thereby realizing the locking and fixing of the rotating body 6, and at this time, the clamping component located on the rotating body 6 is also fixed and cannot rotate.

[0028] The clamping parts respectively include a second stepper motor 4, a gear 17 arranged at the output shaft end of the second stepper motor 4, a first support arm 7 and a second support arm 8. One end of the first support arm 7 is fixedly connected to a first gear bar 18, and one end of the second support arm 8 is fixedly connected to a second gear bar 19. The first gear bar 18 and the second gear bar 19 are both meshed with the gear 17. One end of the first support arm 7 close to the first gear bar 18, the first gear bar 18, the second gear bar 19, one end of the second support arm 8 close to the second gear bar 19, and the gear 17 are all located in the rotating body 6. The second stepper motor 4 is fixedly installed on a side wall of the rotating body 6. The second stepper motor 4 is respectively connected to the first gear bar 18 and the second gear bar 19 through the gear 17. The first support arm 7 and the second support arm 8 are both provided with a slide groove 20. The slide grooves 20 of the first support arm 7 and the second support arm 8 are both slidably connected with a slide bar 9. The surface of the slide bar 9 is provided with a rough texture for anti-slip.

[0029] Specifically, the second stepper motor 4 can realize the forward and reverse rotation of the output shaft by changing the control circuit. When the second stepper motor 4 rotates forward, the second stepper motor 4 drives the gear 17 to rotate clockwise, and the first gear bar 18 and the second gear bar 19 meshing with the gear 17 move toward each other, the first gear bar 18 pulls the first support arm 7, and the second gear bar 19 pulls the second support arm 8 to move toward each other, and the first support arm 7 and the second support arm 8 are close to each other to achieve clamping. When the second stepper motor 4 drives the gear 17 to rotate counterclockwise, the first gear bar 18 and the second gear bar 19 meshing with the gear 17 move away from each other, and the first support arm 7 and the second support arm 8 move away from each other, so as to achieve release and no longer clamp the motor.

[0030] The middle parts of both side walls of the table top 1 are fixedly connected with connecting bolts 10 , and limiting holes 11 are arranged on both side walls of the table top 1 away from the connecting bolts 10 .

[0031] Specifically, the table top 1 is fixedly mounted on a test bench of the electrical equipment. The connecting bolt 10 is hinged to the test bench and is fixed by inserting a pin into a limiting hole 11 .

[0032] When the utility model is applied to motor detection, after the adjustable clamping mechanism is equipped on the motor detection equipment, the control circuit on the electrical equipment is electrically connected to the first stepper motor 3 and the second stepper motor 4 respectively, so as to control the start and stop of the first stepper motor 3 and the second stepper motor 4. The utility model can be used not only for motor detection, but also for other electrical automation equipment, to achieve an adjustable clamping effect in the electrical automation equipment, and meet the clamping needs of height and angle adjustment.

[0033] When in use, the motor to be tested is placed between the first support arm 7 and the second support arm 8 on the table top 1, and the second stepper motor 4 is started. The second stepper motor 4 drives the gear 17 to rotate clockwise, and the first gear bar 18 and the second gear bar 19 meshing with the gear 17 move toward each other, the first gear bar 18 pulls the first support arm 7, and the second gear bar 19 pulls the second support arm 8 to move toward each other, and the first support arm 7 and the second support arm 8 approach and clamp the motor to be tested.

[0034] Start the first stepper motor 3, which drives the sliding block of the ball screw 2 to move upward. The sliding block moves upward and pulls the first support leg 15 and the second support leg 16 upward, and the angle adjustment component and the clamping component on the support legs also move upward. At the same time, the clamped motor to be tested moves upward, and then the motor testing equipment can test the motor to be tested. During the testing process, the angle adjustment component can be used to adjust the angle of the rotating body 6 (the clamping component on the rotating body 6 also adjusts the angle accordingly, and the motor to be tested on the clamping component also adjusts the angle accordingly).

[0035] Hold the handle 12 and rotate the rotating body 6 to make the rotating body 6 rotate in the annular body 5 to adjust the angular position; after adjusting to the appropriate angle by rotation, extend the clamping strip 13 on the handle 12. At this time, the lower end of the clamping strip 13 is hinged to the handle and the lower end portion is embedded in the handle 12. When the clamping strip 13 on the handle 12 is extended, the clamping strip 13 and the handle 12 are vertical, and the non-hinged end of the clamping strip 13 can be clamped in the clamping groove 14. The clamping strip 13 is clamped in the clamping groove 14, and the clamping strip 13 is limited and clamped. The clamping strip 13 and the handle hinged thereto and the rotating body 6 fixedly connected to the handle cannot move, thereby achieving locking and fixation of the rotating body 6. At this time, the clamping component located on the rotating body 6 is also fixed and cannot rotate.

[0036] Through the coordinated arrangement of the angle adjustment component, the clamping component, and the lifting and lowering adjustment component, the adjustable clamping mechanism has the effect of clamping the motor to be tested and adjusting the height and angular position of the motor to be tested. During use, the second stepper motor 4 is used to drive the first support arm 7 and the second support arm 8 to clamp the motor to be tested, the rotating body 6 is used to rotate in the annular body 5 to adjust the angular position of the motor to be tested, and the first stepper motor is used to drive the ball screw to drive the supporting leg to move up and down as a whole to adjust the height position of the motor to be tested. Under the premise of ensuring that the motor detection equipment can effectively clamp and fix the motor to be tested, the height and angular position of the motor to be tested can be effectively adjusted, thereby improving the motor detection efficiency.
