Description

Technical Field

[0001] This utility model relates to the field of motor controller testing technology, and in particular to a motor controller testing device that is easy to replace. Background Technology

[0002] In the testing process of motor controllers, the fixation of the motor is a crucial step. Currently, the traditional method of fixing motors for testing mostly uses screws and nuts.

[0003] This fixing method has many drawbacks. On the one hand, the installation and adjustment process is cumbersome, requiring staff to spend a lot of time and energy tightening the screws and nuts, resulting in high labor intensity and low work efficiency. On the other hand, because different staff members cannot tighten the screws and nuts with consistent force, it is very easy for the installation position of the test motor to deviate. In severe cases, this positional deviation will not only damage the test motor, but also damage the brake used in conjunction with the test motor, thereby affecting the normal operation of the entire test equipment and the accuracy of the test results.

[0004] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: the traditional method of fixing test motors is basically to use screws and nuts. This method is not only labor-intensive and inefficient, but also may cause slight deviations in the position of the test motor due to different tightening forces of the screws and nuts by the workers. In severe cases, it may even damage the test motor and brake, affecting the equipment. Therefore, to address the above problems, a motor controller testing device with convenient replacement is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the existing technology, where the traditional method of fixing test motors is basically to use screws and nuts. This method is not only labor-intensive and inefficient, but also prone to slight deviations in the position of the test motor due to different tightening forces of the screws and nuts. In severe cases, it may even damage the test motor and brake, affecting the equipment. Therefore, this utility model proposes a motor controller test device that is easy to replace.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a convenient motor controller testing device, comprising a workbench, a fixing plate fixedly connected to the surface of the workbench, a lower semicircular block fixedly connected to the surface of the fixing plate, a rotating groove formed on the surface of the lower semicircular block, a fixing device provided on the inner wall of the rotating groove of the lower semicircular block, the fixing device including a fixing rod fixedly connected to the inner wall of the rotating groove of the lower semicircular block, a rotating block rotatably connected to the arc surface of the fixing rod, an upper semicircular block fixedly connected to the surface of the rotating block, a placement block fixedly connected to the surface of the lower semicircular block, a fixing block fixedly connected to the surface of the upper semicircular block, the size of the fixing block matching the size of the placement block, a sliding rod slidably inserted into the surface of the placement block, an elliptical block fixedly connected to the other end of the sliding rod, a sliding groove formed on the surface of the fixing block, the upper and lower semicircular blocks clamping a test motor, and a brake fixedly connected to the surface of the workbench.

[0007] The effect achieved by the above-mentioned components is as follows: by setting up a fixing device, a convenient fixing effect can be achieved. When the staff uses it, it avoids the situation where the traditional method of fixing test motors is basically to fix them with screws and nuts. This method is not only labor-intensive and inefficient, but also may cause slight deviations in the position of the test motor due to different tightening force of the screws and nuts by the staff. In severe cases, it may even damage the test motor and brake, affecting the equipment.

[0008] Preferably, the arc surface of the fixing rod is fitted with a torsion spring, and the two ends of the torsion spring are respectively fixedly connected to the inner wall of the rotating block and the rotating groove of the lower semicircular block.

[0009] The effect achieved by the above components is that, through the cooperation between the torsion spring rotating block and the inner wall of the lower semicircular block rotating groove, the upper semicircular block can be easily opened by the operator due to the torsion force of the torsion spring itself.

[0010] Preferably, the arc surface of the sliding rod is fitted with a spring, and the two ends of the spring are fixedly connected to the surfaces of the elliptical block and the placement block, respectively.

[0011] The effect achieved by the above components is as follows: through the cooperation of the spring elliptical block and the placement block, when the elliptical block is pulled, the elliptical block drives the sliding rod to disengage from the slide groove. Due to the elasticity of the spring itself, when the operator releases the elliptical block, the spring will automatically drive the sliding rod to re-insert into the slide groove.

[0012] Preferably, the arc surfaces of both the lower and upper semicircular blocks are fixedly connected with anti-slip pads, and the size of the sliding groove is adapted to the size of the sliding rod.

[0013] The effect achieved by the above components is that, through the cooperation of the lower semicircular block, the upper semicircular block, and the anti-slip pad, it can be ensured that the test motor will not slip.

[0014] Preferably, the surface of the workbench is provided with an auxiliary device, the auxiliary device including a placement compartment, the placement compartment being fixedly connected to the surface of the workbench, two mounting blocks being fixedly connected to the surface of the placement compartment, a rotating rod being fixedly connected to one side of the mounting blocks that are close to each other, and a cover plate being rotatably connected to the arc surface of the rotating rod.

[0015] The effect achieved by the above-mentioned components is that by setting up auxiliary devices, tools can be effectively stored. When staff find that the device has a problem, they can directly take out the tools from the auxiliary devices for repair, thereby avoiding the time wasted by staff having to retrieve the tools. In addition, the working efficiency of the machine is improved and the practicality of the device is enhanced.

[0016] Preferably, the surface of the cover plate is fixedly connected with a hook and loop fastener, and the surface of the hook and loop fastener is adhered with a hook and loop rough surface, which is fixedly connected to the surface of the placement compartment.

[0017] The effect achieved by the above components is that, through the cooperation of the hook and loop side and the hook and loop flat side, the cover can be glued to the surface of the storage compartment when not in use, preventing the cover from being opened when not in use.

[0018] Preferably, two upright blocks are fixedly connected to the surface of the cover plate, and a flat plate is fixedly connected to the surface of each upright block.

[0019] The effect achieved by the above components is that, through the cooperation of the cover plate uprights and the flat panel, it is convenient for staff to open the cover plate.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] 1. In this utility model, by setting a fixing device, the effect of convenient fixing can be achieved. When the staff uses it, it avoids the situation where the traditional method of fixing the test motor is basically fixed with screws and nuts.

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a convenient motor controller testing device, including a workbench 1, a fixing plate 2 fixedly connected to the surface of the workbench 1, a lower semicircular block 3 fixedly connected to the surface of the fixing plate 2, a rotating groove opened on the surface of the lower semicircular block 3, and a fixing device 5 provided on the inner wall of the rotating groove of the lower semicircular block 3. By setting the fixing device 5, the effect of convenient fixing can be achieved. When the operator uses it, it avoids the problem that the traditional method of fixing the test motor 8 is basically fixed with screws and nuts. This method is not only labor-intensive and inefficient, but also may cause slight deviations in the position of the test motor 8 due to different tightening force of the screws and nuts by the operator. In severe cases, it may even damage the test motor 8 and the brake 7, affecting the equipment. The surface of the workbench 1 is provided with an auxiliary device 6. By setting the auxiliary device 6, the tools can be effectively stored. When the operator finds a problem with the device, the tools can be directly taken out from the auxiliary device 6 for repair, thereby avoiding the time wasted by the operator to retrieve the tools, and improving the working efficiency of the machine and the practicality of the device.

[0030] The following section will describe in detail the specific setup and function of its fixing device 5 and auxiliary device 6.

[0031] Reference Figure 2 , Figure 3 and Figure 4 As shown in this embodiment: the fixing device 5 includes a fixing rod 501, which is fixedly connected to the inner wall of the rotating groove of the lower semicircular block 3. A rotating block 502 is rotatably connected to the arc surface of the fixing rod 501. An upper semicircular block 4 is fixedly connected to the surface of the rotating block 502. A placement block 503 is fixedly connected to the surface of the lower semicircular block 3. A fixing block 504 is fixedly connected to the surface of the upper semicircular block 4. The size of the fixing block 504 is adapted to the size of the placement block 503. A sliding rod 505 is slidably inserted into the surface of the placement block 503. An elliptical block 506 is fixedly connected to the other end of the sliding rod 505. A groove 507 is opened on the surface of the fixing block 504. The upper semicircular block 4 and the lower semicircular block 3 clamp the test motor 8. A brake 7 is fixedly connected to the surface of the worktable 1. A torsion spring 508 is sleeved on the arc surface of the fixing rod 501. The two ends of the torsion spring 508 are fixedly connected to the inner walls of the rotating grooves of the rotating block 502 and the lower semicircular block 3, respectively. Spring 509 is fitted onto the arc surface of 505. The two ends of spring 509 are fixedly connected to the surfaces of elliptical block 506 and placement block 503, respectively. Anti-slip pads 510 are fixedly connected to the arc surfaces of lower semicircular block 3 and upper semicircular block 4. The size of slide groove 507 is adapted to the size of sliding rod 505. Through the cooperation of torsion spring 508 rotating block 502 and the inner wall of the rotating groove of lower semicircular block 3, the upper semicircular block 4 can be easily opened by the operator due to the torsion of torsion spring 508 itself. Through the cooperation of spring 509, elliptical block 506 and placement block 503, when elliptical block 506 is pulled, elliptical block 506 drives sliding rod 505 out of slide groove 507. Due to the elasticity of spring 509 itself, when the operator releases elliptical block 506, spring 509 will automatically drive sliding rod 505 to re-insert into slide groove 507. Through the cooperation of lower semicircular block 3, upper semicircular block 4 and anti-slip pads 510, it can be ensured that the test motor 8 will not slip.

[0032] Reference Figure 5 As shown, specifically, the auxiliary device 6 includes a placement compartment 61, which is fixedly connected to the surface of the workbench 1. Two mounting blocks 62 are fixedly connected to the surface of the placement compartment 61. A rotating rod 63 is fixedly connected to one side of the mounting blocks 62 that is close to each other. A cover plate 64 is rotatably connected to the arc surface of the rotating rod 63. A hook and loop fastener plane 66 is fixedly connected to the surface of the cover plate 64. A hook and loop fastener rough surface 65 is pasted onto the surface of the hook and loop fastener plane 66. The hook and loop fastener rough surface 65 is fixedly connected to the surface of the placement compartment 61. Two upright blocks 67 are fixedly connected to the surface of the cover plate 64. A flat plate 68 is fixedly connected to the surface of the upright blocks 67. Through the cooperation of the hook and loop fastener rough surface 65 and the hook and loop fastener plane 66, the cover plate 64 can be pasted onto the surface of the placement compartment 61 when not in use, preventing the cover plate 64 from being opened when not in use. Through the cooperation of the upright blocks 67 and the flat plate 68 of the cover plate 64, the staff can easily open the cover plate 64.

[0033] Working principle: When the operator needs to open the fixing device 5, the operator pulls the elliptical block 506, which drives the sliding rod 505 to slide. At this time, the spring 509 is in a stretched state, and the sliding rod 505 slides within the placement block 503. The sliding rod 505 slides away from the inner wall of the slide groove 507. At this time, due to the torsion force of the torsion spring 508, the torsion spring 508 drives the rotating block 502 to rotate. The rotating block 502 drives the upper semicircular block 4 to rotate. The upper semicircular block 4 drives the anti-slip pad 510 to move. The upper semicircular block 4 drives the fixing block 504 to move away from the inner surface of the placement block 503, thus the operator completes the fixing of device 5. When opened, the upper semicircular block 4 can be easily opened by the cooperation of the torsion spring 508 rotating block 502 and the inner wall of the rotating groove of the lower semicircular block 3. Due to the torsion of the torsion spring 508 itself, the upper semicircular block 4 can be opened by the operator. Through the cooperation of the spring 509 elliptical block 506 and the placement block 503, the elliptical block 506 can be pulled, and the elliptical block 506 will drive the sliding rod 505 to disengage from the slide groove 507. Due to the elasticity of the spring 509 itself, when the operator releases the elliptical block 506, the spring 509 will automatically drive the sliding rod 505 to re-insert into the slide groove 507. Through the cooperation of the lower semicircular block 3, the upper semicircular block 4 and the anti-slip pad 510, it can be ensured that the test motor 8 will not slip.

[0034] When a worker needs to retrieve a tool, they pull the flat panel 68. The flat panel 68 drives the upright block 67, which in turn drives the cover plate 64 to rotate. The cover plate 64 causes the hook and loop fastener surface 66 to disengage from the hook and loop fastener surface 65. The cover plate 64 rotates on the arc surface of the rotating rod 63, thus opening the cover. After the worker retrieves the tool, they release the flat panel 68. The cover plate 64 rotates and automatically closes due to its own weight. Through the cooperation of the hook and loop fastener surface 65 and the hook and loop fastener surface 66, the cover plate 64 can be attached to the surface of the storage compartment 61 when not in use, preventing it from opening when not in use. Through the cooperation of the upright block 67 and the flat panel 68, the cover plate 64 can be easily opened by the worker.
