Description

Technical Field

[0001] The utility model relates to the technical field of torque testing, and specifically discloses a torque machine. Background Art

[0002] The reducer is an independent component consisting of a gear transmission, a worm transmission, or a gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching the speed and transmitting the torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery. When producing reducers, torque detection equipment is required to determine whether the torque of the reducer is qualified. The existing torque detection method generally requires the inspector to hold a fixed wrench in one hand to limit the rotation of the output shaft, and hold a torque wrench in the other hand to apply torque to the input shaft. This detection method may cause the output shaft to rotate due to the lack of coordination between the inspector's hands, thereby affecting the detection results. On the other hand, it is convenient for manual operation, and the safety factor may be relatively low due to misoperation.

[0003] In order to solve this problem, the present application provides a torque machine which can automatically perform torque testing on a reducer. Utility Model Content

[0008] A protective cover is arranged above the test machine, which covers the entire dynamic torque sensor and partially covers the first coupling and the second coupling.

[0025] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0026] Example

[0027] In order to solve the defects of the traditional reducer 60 torque detection, refer to Figure 1 and Figure 2 As shown, the present application discloses a torque machine, including a test machine 10 and a mounting mechanism 20, a dynamic torque sensor 30 and a load brake 40 sequentially arranged on the test machine 10 in one direction;

[0028] The mounting mechanism 20 includes a telescopic drive assembly 21 fixed on the test machine 10, a mounting seat 22 connected to the driving part of the telescopic drive assembly 21, and a test motor 50 detachably fixed on the mounting seat 22 and having an output shaft connected to a reducer 60;

[0029] The input shaft and output shaft of the dynamic torque sensor 30 are respectively connected with a first coupling 31 and a second coupling 32. The output end of the reducer 60 passes through the mounting seat 22 and is connected to the dynamic torque sensor 30 through the first coupling 31. The input end of the load brake 40 is connected to the dynamic torque sensor 30 through the second coupling 32.

[0030] A protective cover 90 is arranged above the test machine, covering the entire dynamic torque sensor 30 and partially covering the first coupling 31 and the second coupling 32 .

[0031] As a preference of the present application, the telescopic drive assembly 21 includes two servo screw modules 211, and the mounting seat 22 is connected to the screw seats (known structure) of the two servo screw modules 211. In actual use, if other types of telescopic drive assemblies 21 can replace the two servo screw modules 211 of the present application, personnel in this technical field can also adopt them adaptively.

[0032] The present application also provides a blocking block 80 between the two servo screw modules 211 near the conveying end. The blocking block 80 has a mounting groove 81 on the side facing the mounting seat 22. A partially leaking contact switch 120 is installed in the mounting groove 81. After the two servo screw modules 211 drive the mounting seat 22 to move and are blocked by the blocking block 80, the contact switch 120 will contact the mounting seat 22, thereby controlling the two servo screw modules 211 to stop driving the mounting seat 22 to move. At this time, it means that the output end of the reducer 60 has been plugged into the first coupling 31.

[0033] Specifically, the mounting seat 22 of the present application is an L-shaped mounting seat, and a reinforcing plate 221 is arranged on one side of the L-shaped mounting seat for mounting the test motor 50 and the reducer 60. By setting the reinforcing plate 221, it can be ensured that the L-shaped mounting seat has strong stability and will not be deformed during use.

[0034] The following is the installation method of the reducer 60 equipped with the test motor 50 on the L-shaped mounting seat of the present application. A through hole 222 for the output end of the reducer 60 to pass through is opened on the vertical portion of the L-shaped mounting seat. A plurality of screw holes (not marked in this application) are arranged in a rectangular array on the vertical portion of the L-shaped mounting seat with the through hole 222 as the center. When the test motor 50 and the reducer 60 are installed on the L-shaped mounting seat, all the connection holes of the end cover of the reducer 60 are screwed with screws 23 into the screw holes of the L-shaped mounting seat. This method is used to fix the reducer 60 to the mounting seat 22, which can facilitate the operator to remove it later.

[0035] In one of the specific embodiments, the present application provides an observation window at the top of the protective cover 90, and a protective glass 100 is installed in the observation window. A torque digital display 110 electrically connected to the dynamic torque sensor 30 is installed on the main viewing surface of the protective cover 90. During specific use, the operator can detect the transmission status of the dynamic torque sensor 30 and the first coupling 31 and the second coupling 32 in real time, and can understand the torque value detected by the reducer 60 in real time through the torque digital display 110.

[0036] In order to install the first coupling 31 and the second coupling 32 on the input shaft and the output shaft of the dynamic torque sensor 30 respectively, the present application fixes the dynamic torque sensor 30 to the test machine 10 via a pad bracket 70 .

[0037] During specific use, the operator first installs the reducer 60 to be tested on the test motor 50, and can lock it on the mounting base 22 by means of the screws 23. When the telescopic drive assembly 21 is controlled to drive the mounting base 22 to move, the drive shaft of the reducer 60 can be plugged into the first coupling 31. When the test motor 50 is controlled to work, the reducer 60 is transmitted to the dynamic torque sensor 30 through the first coupling 31, and the load brake 40 is transmitted to the dynamic torque sensor 30 through the second coupling 32. At this time, the dynamic torque sensor 30 can test the torque value in real time.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0039] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable technicians familiar with the technical field to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
