[0041] Reference Figures 1 to 3 The present invention relates to an electric caliper efficiency testing device, comprising: a base 100; a motor 200 disposed on the base 100; a reduction gearbox 300 disposed on the base 100, wherein a first torque sensor 210 and a first angle encoder 220 are disposed between the motor 200 and the reduction gearbox 300; and an output component 400 disposed on the base 100, wherein the output component 400 is connected to the caliper 500 and is used to drive the caliper 500 to rotate, wherein a second torque sensor 410 and a second angle encoder 420 are disposed between the output component 400 and the reduction gearbox 300.

[0042] The above-mentioned electric caliper efficiency testing device has at least the following beneficial effects: the output torque and output speed of the motor 200 are measured by the first torque sensor 210 and the first angle encoder 220, thereby obtaining the input power of the gearbox 300; the output torque and output speed of the gearbox 300 are measured by the second torque sensor 410 and the second angle encoder 420, thereby obtaining the output power of the gearbox 300; and thus obtaining the output efficiency of the entire electric caliper 500 from the motor 200 to the caliper 500.

[0043] According to some embodiments of this utility model, a first mounting plate 110 and a second mounting plate 120 are provided on the base 100. A motor 200 is mounted on the first mounting plate 110, and a reduction gearbox 300 is mounted on the second mounting plate 120. The output shaft of the motor 200 is parallel to the axes of the input and output ends of the reduction gearbox 300. Figure 1 As can be seen, the output shaft of the motor 200 is aligned with the input and output ends of the gearbox 300. One end of the first drive shaft 230 is connected to the output end of the motor 200 via a synchronous belt mechanism 240, and the other end is connected to the first torque sensor 210 via a universal joint 250. The first torque sensor 210 is connected to the first angle encoder 220 via the universal joint 250. This arrangement can shorten the shaft distance between the motor 200 and the gearbox 300, reducing the error caused by excessive shaft length. The gearbox also includes a second drive shaft 260, one end of which is connected to the first angle encoder 220, and the other end is connected to the input end of the gearbox 300. The first drive shaft 230 and the second drive shaft 260 are coaxially aligned.

[0044] According to some embodiments of the present invention, it also includes a third drive shaft 310 and a fourth drive shaft 320. One end of the third drive shaft 310 is connected to the output end of the reduction gearbox 300. The other end of the third drive shaft 310 and one end of the fourth drive shaft 320 are respectively connected to the two sides of the second torque sensor 410 through a universal joint 250. The other end of the fourth drive shaft 320 is connected to the output component 400.

[0045] According to some embodiments of this utility model, a first synchronous pulley 330 is provided on the fourth drive shaft 320, and a second synchronous pulley 340 is connected to the second angle encoder 420. The first synchronous pulley 330 and the second synchronous pulley 340 are connected by a first synchronous belt 350. Through the action of the first synchronous pulley 330, the second synchronous pulley 340 and the first synchronous belt 350, the second angle encoder 420 is moved to the outside of the fourth drive shaft 320. This not only maintains the same rotation speed through the first synchronous belt 350, but also shortens the shaft length and reduces the error caused by an excessively long shaft.

[0046] According to some embodiments of this utility model, it also includes a force measuring component, which is disposed on the base 100. The caliper 500 clamps the force measuring component, and a first sensor is provided on the force measuring component. The output torque of the motor is calculated by the output power and output speed of the motor, and the clamping force of the caliper 500 is measured by the first sensor, so that the efficiency of the overall output power from the motor to the caliper can be calculated.

[0047] According to some embodiments of this utility model, it also includes an elastic adjustment component, which includes: two support plates 600, both disposed on the base 100; a connecting rod 610, with each end connected to a support plate 600; a slider 620 slidably disposed on the connecting rod 610, with elastic elements 630 respectively disposed between the two sides of the slider 620 and the two support plates 600; a third mounting plate 640 disposed on the slider 620, and a force measuring element disposed on the third mounting plate 640. The two elastic elements 630 ensure that the slider 620 and the third mounting plate 640 are always kept in a centered position, ensuring that the force measuring element is only affected by the clamping force and not disturbed by other external forces. It should be noted that... Figure 1 The force measuring component is in a hidden state.

[0048] In some other embodiments, the force measuring element can also be directly provided on the slider 620, and the elastic elements 630 provided on both sides of the slider 620 can all be tension springs or compression springs.

[0049] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", and "extended embodiment" may be used to describe several embodiments of the present invention, and the specific features, structures, materials or characteristics of the several embodiments may be combined in accordance with the principles and spirit of the present invention.

As long as they achieve the technical effects of the present invention by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations of these embodiments within the spirit and principles of this disclosure, without departing from the principles and purpose of the present invention, should be included within the scope of protection of this disclosure and should be considered to fall within the protection scope of the present invention.
