Embodiment
The purpose of this utility model is to provide a kind of torque adjusting device, the utility model is made with reference to embodiment into
One step describes in detail.
Embodiment
As shown in Figure 1, a kind of torque adjusting device, including the output shaft 5 for output torque, the tune easy to artificial applying power
Save knob 1 and mounting base 3.The output shaft 5 is connected with testing the lower end of spring 4, and the upper end of test spring 4 connects with splined shaft 2
Connect.
In the present embodiment, splined shaft 2 is designed, the splined shaft 2 is solid construction, and top is equipped with external splines,
Lower part outer wall is equipped with trapezoidal thread.The lower part of splined shaft 2 and test spring 4 are all arranged in mounting base 3.In the mounting base 3
Equipped with the screw thread engaged with 2 lower part trapezoidal thread of splined shaft.
The adjusting knob 1 is equipped with the space that can accommodate splined shaft 2.It is additionally provided with adjusting knob 1 and 2 top of splined shaft
Engage the internal spline 8 of connection so that when adjusting knob 1 rotates, splined shaft 2 can be transmitted force to by internal spline 8.
It is emphasized that in order to ensure the stable degree of structure, the mounting base 3 is equipped with accommodation space, respectively lower to hold
Receive passage and upper receiving channel, lower receiving channel is connected with upper receiving channel, and the diameter of lower receiving channel is less than upper receiving channel
5 top of diameter and output shaft diameter so that output shaft 5 can be up and down in lower receiving channel, but will not be from peace
Skidded off in dress seat 3, the lower part of output shaft 5 is arranged in lower receiving channel, and test spring 4,2 lower part of splined shaft are arranged on receiving
In passage, the above-mentioned screw thread engaged with 2 lower part trapezoidal thread of splined shaft is also disposed in upper receiving channel.
The adjusting knob 1 can rotate in mounting base 3, and not fall off, stable connection, and the top of mounting base 3 is set
There is a ring annular groove, the external groove sidevall of the annular groove is arc.1 bottom of adjusting knob is equipped with card slot 10 and is used to be caught in annular
In groove so that adjusting knob 1 can be rotated relative to mounting base 3.The opening of card slot 10 makes towards the arc external groove sidevall of annular groove
Obtain and a space is formed between card slot 10 and annular groove, at least one anticreep group is equipped with the space between card slot 10 and annular groove
Part, the anti-drop assembly all include fixed spring 7 and steel ball 6, and one end of the fixed spring 7 is connected with steel ball 6, fixed spring
Towards the slot bottom of card slot 10, steel ball 6 is bonded 7 other end with arc external groove sidevall.Fixed spring 7 gives 6 elastic force of steel ball so that steel ball
6 are close to arc external groove sidevall all the time, and arc external groove sidevall blocks steel ball 6, and steel ball 6 pushes down the lower cell wall of card slot 10, so that adjusting
Knob 1 cannot come off from mounting base 3, and can be rotated in mounting base 3.

The objects such as handle are can be inserted into hole 9 to help to rotate.
Further, motor output torque is tested for convenience, the mounting base 3 is equipped with scale markings.
The operation principle of the present embodiment is as follows, and structure described in the present embodiment can be by adjusting knob 1 come regulation output shaft 5
The power of output, then when the output torque carried out to motor is tested, the axis of motor drives test block to rotate, torque
The output shaft 5 of adjuster props up test block, and is rotated by 1 output shaft 5 of adjusting knob, until test block stops operating,
Illustrate that the torque of torque adjusting device output at this time is identical with the torque that motor exports, so that the torque to motor output is surveyed
Examination.The output torque of torque adjusting device is calculated by being connected to the decrement of test spring 4.When adjusting knob 1 rotates
When, the matching of internal spline 8 and external splines causes splined shaft 2 to also begin to rotate, and the trapezoidal thread of 2 lower part of splined shaft and with
Its matched 3 screw thread of mounting base causes trapezoidal thread to decline, so that splined shaft 2 is moved down relative to internal spline 8, due to output
Axis 5 props up test block, then tests spring 4 at this time and necessarily compresses, the elastic force of test spring 4 increases output shaft 5 to survey
The pressure of test specimen, so as to increase frictional force, when test block stops operating, illustrates the power phase that frictional force is exported with motor
Together, say at this time and may know that test 4 decrement of spring turns so as to calculate the output of motor by the scale mark in mounting base 3
Square.
