[0002] The Chinese utility model patent with patent number ZL202123405017.X and patent name, entitled "A Gearbox Backlash Difference Testing Device," discloses the following technical solution: A gearbox backlash difference testing device includes a gearbox, a gearbox motor, and a base. Two abutments and one abutment are fixedly installed on the top of the base. A sliding hole is provided on the side of the base, and a slider slides in contact with the sliding hole. An L-shaped abutment is provided on the side of the slider. Rectangular grooves one and two are respectively provided on the L-shaped abutment and the base. A counterweight and a frame slide in contact with each other in rectangular grooves one and two, respectively. An insert is provided on the side of the counterweight, and the insert is engaged with the frame. A pull rod and a fixing strip are respectively provided on the top of the counterweight and the frame. A fixing groove is provided at the bottom of the slider, and the fixing strip is engaged with the fixing groove. A spring is welded between the inner wall of the bottom of the frame and the rectangular groove two.

[0003] During the backlash test of the gearbox using the aforementioned gearbox backlash test device, the gearbox is placed on the base, and then pushed to the left so that one side of the gearbox contacts the second stop block. Next, the second pull rod is pushed, and the L-shaped stop block and the slider move to the left simultaneously, allowing the insert to be inserted into the frame first, until the fixing strip connects with the fixing groove. The spring returns to its original position, allowing the frame, insert, counterweight, first pull rod, and fixing strip to move upward simultaneously until the fixing strip is inserted into the fixing groove. This allows for quick fixation of the gearbox, facilitating gearbox testing.

[0004] It should be noted that the aforementioned gearbox backlash test device has the following drawbacks: its overall structure is complex, the test operation is inconvenient, and it cannot intuitively display backlash information. Utility Model Content

[0005] The purpose of this utility model is to provide a gearbox motor backlash detection fixture to address the shortcomings of the existing technology. This gearbox motor backlash detection fixture has a novel design, simple structure, and is easy to operate and use. It can also intuitively display backlash information.

[0026] 1-Dial; 2-360° angle scale; 3-Center circular hole; 4-Screw mounting hole; 5-Gearbox motor; 51-Output shaft; 52-Locking plane; 6-First locking screw; 7-Moving pointer; 71-Pointer through hole; 72-Pointer internal thread hole; 8-Second locking screw. Detailed Implementation

[0027] The present invention will now be described in conjunction with specific embodiments.

[0028] Example 1, as Figures 1 to 3 As shown, a gearbox motor backlash detection fixture includes a fixture body, which includes a disc-shaped scale 1. The upper surface of the scale 1 is provided with 360° angle scales 2. It should be noted that the scale 1 in this embodiment can be made of stainless steel.

[0029] Among them, such as Figure 3 As shown, a vertically penetrating central circular hole 3 is provided in the middle of the dial 1, and at least two spaced screw mounting holes 4 are provided on the side of the central circular hole 3. Each screw mounting hole 4 is equipped with a first locking screw 6 that is screwed into the gearbox motor 5.

[0030] Furthermore, the gearbox motor backlash detection fixture also includes a movable pointer 7. It should be noted that the movable pointer 7 in this embodiment can be made of stainless steel.

[0031] It should be noted that when the gearbox motor 5 is tested using the gearbox motor backlash detection fixture, the gearbox motor 5 is fastened to the lower surface of the dial 1 by the first locking screw 6, and the output shaft 51 of the gearbox motor 5 passes through the central circular hole 3 of the dial 1 from bottom to top. The movable pointer 7 is mounted on the output shaft 51 of the gearbox motor 5 and is located above the dial 1.

[0032] When testing the backlash difference of the gearbox motor 5, the gearbox motor 5 is powered on and controlled to rotate in the forward and reverse directions in sequence. The angle values ​​of the gearbox motor 5 during forward and reverse rotation are read by using the movable pointer 7 in conjunction with the 360° angle scale 2. The backlash difference of the gearbox motor 5 can be obtained based on the above angle values.

[0033] It should be emphasized that the gearbox motor backlash difference detection fixture in this embodiment only includes a dial 1, a movable pointer 7, and a first locking screw 6. Compared with the prior art, the overall structure of the gearbox motor backlash difference detection fixture in this embodiment is simpler.

[0034] When performing backlash detection on the gearbox motor 5, the gearbox motor 5 is directly locked to the lower surface of the dial 1 by the first locking screw 6, and the backlash information can be intuitively known by the indicated angle value of the movable pointer 7. That is, the test operation is convenient and the backlash information can be displayed intuitively.

[0035] In summary, the gearbox motor backlash detection fixture of this embodiment has the advantages of novel design, simple structure and convenient operation, and can intuitively display backlash information through the above structural design.

[0036] Example 2, as Figure 3 As shown, the difference between this embodiment 2 and embodiment 1 is that: the fixed end of the movable pointer 7 is provided with a vertically penetrating pointer through hole 71, and the side wall of the pointer through hole 71 is provided with a horizontally extending pointer internal thread hole 72 that opens outwards, and the pointer internal thread hole 72 is internally threaded with a second locking screw 8.

[0037] When the gearbox motor 5 is tested using the gearbox motor backlash detection fixture, the output shaft 51 of the gearbox motor 5 is inserted into the pointer through hole 71 of the movable pointer 7, and the second locking screw 8 abuts against the output shaft 51 of the gearbox motor 5, so as to achieve the fixed end of the movable pointer 7 and the output shaft 51 of the gearbox motor 5 to prevent rotation.

[0038] Example 3, as Figure 1 and Figure 3 As shown, the difference between this embodiment three and embodiment two is that the output shaft 51 of the gearbox motor 5 is provided with a locking plane 52.

[0039] When the gearbox motor 5 is tested using the gearbox motor backlash detection fixture, the second locking screw 8 abuts against the locking plane 52 of the output shaft 51 of the gearbox motor 5.

[0040] By setting the locking plane 52 structure, this embodiment can effectively ensure that the movable pointer 7 and the output shaft 51 of the gearbox motor 5 are connected to prevent rotation, resulting in good stability and reliability.

[0041] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
