Description

Technical Field

[0001] The utility model relates to the technical field of a reducer performance test device, in particular to a harmonic reducer starting torque factory test device. Background Art

[0002] Before the harmonic reducer leaves the factory, various working indicators of the harmonic reducer need to be tested, among which the starting torque of the harmonic reducer is one of them.

[0003] In the existing starting torque test of the harmonic reducer, it is usually necessary to connect the input shaft of the harmonic reducer and the output shaft of the motor through a coupling, and then drive the input shaft of the harmonic reducer to rotate by the motor to test the starting torque of the harmonic reducer.

[0004] However, in the actual starting torque test, it is only necessary to drive the input shaft of the harmonic reducer to rotate, and the starting process of the harmonic reducer only takes a few seconds; while in the above test process, each test requires the disassembly and assembly of the coupling between the harmonic reducer and the motor, and multiple bolts need to be disassembled and assembled in the circumferential direction of the coupling; the disassembly and assembly process time of the coupling is much longer than the starting process of the harmonic reducer, which increases the overall test time of the starting torque of the harmonic reducer and reduces the test efficiency of the starting torque of the harmonic reducer. Utility Model Content

[0005] In view of the above problems, the utility model provides a harmonic reducer starting torque factory test device, the purpose of which is to improve the test efficiency of the harmonic reducer starting torque.

[0006] In order to achieve the above-mentioned invention object, the technical solution adopted by the utility model is as follows:

[0007] A harmonic reducer starting torque factory test device is provided, comprising: a device body for placing a harmonic reducer; a motor, which is arranged on the device body; a turntable, which is rotatably arranged on the device body; a torque sensor, one end of which is connected to the turntable and the other end is connected to the output shaft of the motor; a clamping component, which is installed on the turntable and can clamp the input shaft of the harmonic reducer and limit the circumferential rotation of the input shaft of the harmonic reducer; and a clamping assembly, which is installed on the device body and is used to press the harmonic reducer against the clamping component.

[0008] Furthermore, the clamping component includes: a component body, which is detachably mounted on the turntable; a mounting hole, which is opened on the component body for inserting the input shaft of the harmonic reducer; and a clamping block, which is arranged in the mounting hole and is used to clamp the keyway on the input shaft of the harmonic reducer.

[0009] Furthermore, the clamping block includes: a screw, which is installed on the component body through threaded connection along the radial direction of the mounting hole; and an abutment block, which is arranged at one end of the screw and is made of rubber and is used to abut the input shaft of the harmonic reducer.

[0010] Furthermore, the abutment block is hemispherical.

[0011] Furthermore, the clamping assembly includes: a plurality of telescopic components installed on the component body along the axial direction of the input shaft of the harmonic reducer; a plurality of pressure blocks arranged on the piston rod of each telescopic component, which can approach / move away from the harmonic reducer with the telescopic movement of the telescopic component.

[0012] Furthermore, the device also includes: a first coupling, used for transmission connection between the torque sensor and the motor; and a second coupling, used for transmission connection between the torque sensor and the turntable.

[0013] The beneficial effects of the utility model are as follows: in the utility model, the traditional installation method of connecting the input shaft of the harmonic reducer and the torque sensor through a coupling is abandoned, and the circumferential rotation of the input shaft of the harmonic reducer is restricted by directly clamping the clamping component, without the need to disassemble and assemble multiple bolts; the time for installing the transmission connection between the harmonic reducer and the torque sensor can be effectively shortened, and the test efficiency of the starting torque of the harmonic reducer is improved.

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] Reference Figure 1As shown, the embodiment of the present application discloses a harmonic reducer starting torque factory test device, including: a device body 1, used to place the harmonic reducer; a motor 2, arranged on the device body 1; a turntable 3, rotatably arranged on the device body 1; a torque sensor 4, one end of which is connected to the turntable 3 and the other end is connected to the output shaft of the motor 2; a clamping component 5, installed on the turntable 3, capable of clamping the input shaft of the harmonic reducer and limiting the circumferential rotation of the input shaft of the harmonic reducer; a clamping assembly, installed on the device body 1, used to press the harmonic reducer against the clamping component 5.

[0019] In specific use, when it is necessary to test the starting torque of the harmonic reducer, first place the harmonic reducer on the device body 1, insert the input shaft of the harmonic reducer into the clamping component 5, limit the axial rotation of the input shaft of the harmonic reducer, and press the harmonic reducer against the clamping component 5 through the clamping assembly; then start the motor 2, and the motor 2 provides a rotation trend to the turntable 3 through the torque sensor 4 until the torque sensor 4 detects the rotation of the internal shaft, then records the torque value and outputs it.

[0020] In the utility model, the traditional installation method of connecting the input shaft of the harmonic reducer and the torque sensor 4 through a coupling is abandoned, and the circumferential rotation of the input shaft of the harmonic reducer is directly restricted by the clamping component 5, without the need to disassemble and assemble multiple bolts; it can effectively shorten the time for the transmission connection installation between the harmonic reducer and the torque sensor 4, and improve the test efficiency of the starting torque of the harmonic reducer.

[0021] Specifically, the clamping component 5 includes: a component body 51, which is detachably mounted on the turntable 3 and can be mounted on the turntable 3 by screws. The component body 51 of different specifications can be replaced to increase the scope of application; a mounting hole 52, which is opened on the component body 51 for the input shaft of the harmonic reducer to be inserted; a clamping block, which is arranged in the mounting hole 52 and is used to clamp the keyway on the input shaft of the harmonic reducer to limit the rotation of the input shaft of the harmonic reducer.

[0022] It is worth mentioning that when the keyway on the harmonic reducer is a crescent groove, the crescent groove is opened at the end of the input shaft of the harmonic reducer, and the clamping block is set at the bottom of the mounting hole 52. The clamping block can enter the crescent groove to clamp the input shaft of the harmonic reducer.

[0023] Reference Figure 2 As shown, the clamping block includes: a screw 53, which is installed on the component body 51 through a threaded connection along the radial direction of the mounting hole 52; an abutment block 54, which is arranged at one end of the screw 53 and is made of rubber for abutting the input shaft of the harmonic reducer.

[0024] It is worth mentioning that when the keyway on the harmonic reducer is a round head slot, the staff can drive the abutment block 54 to move along the radial direction of the mounting hole 52 by turning the screw 53, thereby driving the abutment block 54 into the round head slot, thereby clamping the input shaft of the harmonic reducer.

[0025] Furthermore, the abutment block 54 is hemispherical, and the staff can drive the abutment block 54 to move along the radial direction of the mounting hole 52 by turning the screw 53, thereby driving the abutment block 54 to enter the round head groove and squeeze the abutment block 54, gradually increasing the contact area between the abutment block 54 and the round head groove, and ensuring the stability of the abutment block 54 in the round head groove.

[0026] Furthermore, the clamping assembly includes: a plurality of telescopic components 61, which are installed on the component body 51 along the axial direction of the input shaft of the harmonic reducer; a plurality of pressure blocks 62, which are arranged on the piston rod of each telescopic component 61 and can approach / move away from the harmonic reducer with the telescopic movement of the telescopic component 61.

[0027] Specifically, the telescopic component 61 can be a cylinder. When it needs to be used, the cylinder is first inflated, and the piston rod pressure block 62 of the cylinder is pushed a certain distance away from the turntable 3; after the staff inserts the harmonic reducer into the clamping component 5, the inflation is cancelled, and the spring built into the cylinder drives the telescopic rod to contract, driving the pressure block 62 to approach the harmonic reducer and press the harmonic reducer tightly.

[0028] Specifically, the device further includes: a first coupling 71 for transmission connection between the torque sensor 4 and the motor 2 ; and a second coupling 72 for transmission connection between the torque sensor 4 and the turntable 3 .

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the equivalent technology of the claims of the present invention, the present invention is also intended to include these modifications and variations.
