as shown in fig. 1, the knob test fixture of the present embodiment includes a fixture plate 21, a knob fixture 30 for holding a knob 40, and a rotating handle base 50.

The knob clamp 30 and the rotating handle seat 50 are both arranged on the tooling plate 21; the rotating handle seat 50 is provided with an angle scale 51, the angle scale 51 is rotatably provided with a rotating handle 52, the rotating handle 52 is provided with a clamping part for clamping the knob head 401 of the knob 40, and the clamping part is a slot 521 in the embodiment; when the knob clamp is used, the knob 40 is clamped and fixed through the knob clamp 30, then the knob head 401 of the knob 40 is arranged in the slot 521 on the rotating handle 52, and the knob head 401 of the knob 40 can be driven to rotate through the rotating handle 52.

Wherein the angle scales 511 of the angle scale 51 are circumferentially arranged on the tray body 512 of the angle scale 51 centering on the center of the rotation shaft of the rotation handle 52 (see fig. 2). Thus, in the process of driving the knob head 401 of the knob 40 to rotate by rotating the handle 52, the corresponding angle scale can be read, for example, the knob head 401 of the knob 40 is driven to rotate to the first gear of the knob 40 by rotating the handle 52, and the first reading on the angle scale 511 is read; then, the knob head 401 of the knob 40 is driven to rotate to the second gear of the knob 40 by rotating the handle 52, the second reading on the angle scale 511 is read, the difference between the first reading and the second reading is taken, the angle value between the first gear and the second gear of the knob 40 can be obtained, and by analogy, the rotation angle progress of the knob 40 can be obtained.

It is preferable to provide the turning knob 52 as a resistance-adjustable turning knob, so that the knob head 401 of the knob 40 is stopped at a desired position at any time by turning the knob 52 according to the measurement better applied to the progress of the turning angle of the knob 40.

It is preferable to provide a pointing member for pointing the angle scale 511 at the rotating handle 52, which is a pointing groove 522 (see fig. 2) of the rotating handle 52 in this embodiment, for better reading of the angle scale value on the angle scale 511.

The minimum scale value on the angle scale 511 is 1 degree, which facilitates to improve the measurement accuracy of the progress of the rotation angle of the knob 40.

Example 2:

on the basis of embodiment 1, in the present embodiment, as shown in fig. 3 to 6, the knob fixture 30 includes an upper holder 31 and a lower holder 32 for holding the knob 40; the upper clamping seat 31 and the lower clamping seat 32 are both provided with a clamping groove 33, and the radius of the clamping groove 33 is matched with the outer diameter of the clamping end of the knob 40. When the upper holder 31 and the lower holder 32 are closed together, the clamping grooves on the upper holder 31 and the lower holder 32 are closed to form a whole cylindrical groove for clamping the clamping end of the knob 40.

The upper clamping seat 31 is hinged on the lower clamping seat 32, and the lower clamping seat 32 is arranged on the tooling plate 21; taking the orientation of fig. 3 as an example, the upper holder 31 is rotated reversely to open the upper holder 31 and the lower holder 32, so that the clamping end of the knob 40 is placed on the clamping groove 33 of the lower holder 32, and then the upper holder 31 is rotated forward to close the upper holder 31 and the lower holder 32, because the end of the upper holder 31 away from the hinged end is provided with the clamping piece 311, and the end of the lower holder away from the hinged end is provided with the clamping groove 321 for clamping the clamping piece 311, the clamping piece 311 is clamped in the clamping groove 321 during the closing process of the upper holder 31 and the lower holder 32, so that the clamped knob 40 is positioned and fixed.

The side surface of the clamping piece 311 facing the clamping groove 321 is preferably an arc-shaped side surface, so that the clamping piece 311 is clamped in the clamping groove 321 when the upper clamping seat 31 rotates towards the lower clamping seat.

The knob test tool further comprises a pressing driving mechanism, and the output end of the pressing driving mechanism is longitudinally arranged and is in contact connection with the upper clamping seat 31; the pressing driving mechanism is used for driving the output end of the pressing driving mechanism to move towards or away from the upper clamping seat 31. After the knob 40 is clamped by the upper clamping seat 31 and the lower clamping seat 32, the output end of the pressing driving mechanism can be displaced towards the upper clamping seat 31, and further the knob 40 is better clamped by the upper clamping seat 31 and the lower clamping seat 32, so that the knob 40 cannot be driven to rotate in the process of driving the knob head 401 of the knob 40 to rotate by rotating the handle 52.

The pressing driving mechanism is specifically a pressing clamp 60, and the pressing handle 601 of the pressing clamp 60 is rotated upwards, so that the pressing end 602 of the pressing clamp 60 can be displaced towards the upper clamping seat 31, and the knob 40 clamped by the upper clamping seat 31 and the lower clamping seat 32 is clamped; by rotating the pressing handle 601 of the pressing clamp 60 downward, the pressing end 602 of the pressing clamp 60 can be displaced away from the upper holder 31, thereby facilitating the removal or replacement of the knob 40 for testing of other knobs 40.

Example 3:

on the basis of embodiment 1, in this embodiment, the rotating handle seat 50 is transversely slidably disposed on the tooling plate 21, a first slide way is disposed on the tooling plate 21, and the rotating handle seat 50 is transversely slidably disposed on the first slide way, so as to facilitate transverse orbit determination and displacement of the rotating handle seat 50.

During the use, it is fixed to pass through knob anchor clamps 30 centre gripping at first knob 40, then promote rotatory handle seat 50 and make rotatory handle seat 50 towards knob 40 displacement, stop when approaching the knob, make the knob head 401 of knob 40 aim at the slot 521 on the rotatory handle 52 again, continue to make rotatory handle seat 50 towards knob 40 displacement, and then can make the knob head 401 of knob 40 insert in the slot 521 on the rotatory handle 52, and then accessible rotatory handle 52 drives the knob head 401 rotation of knob 40.

After the measurement of the rotation angle progress of the knob 40 is completed, the rotating handle seat 50 can be pushed reversely to take out the clamping of the knob head 401 of the knob 40 by the rotating handle seat 50.

Example 4:

on the basis of embodiment 1, in this embodiment, the knob test fixture further includes a bottom plate 10, a pushing mechanism, and a limiting member; the pushing mechanism and the limiting member 22 are both arranged on the bottom plate 10; the output end of the pushing mechanism is connected with the tooling plate 21, and the pushing mechanism is used for driving the tooling plate 21 to move towards or away from the limiting part 22. The pushing mechanism specifically pushes the clamp 23, the pushing handle 231 pushing the clamp 23 rotates downwards, the pushing end 232 pushing the clamp 23 can move towards the limiting part 22, the tooling plate 21 is driven to move towards the limiting part 22, one end, far away from the pushing end 232, of the tooling plate 21 abuts against the limiting part 22, and therefore the tooling plate 21 can be fixed on the bottom plate 10 in a limiting mode, and the rotation angle process of the knob 40 can be measured conveniently on the tooling plate.

After the measurement of the rotation angle process of the knob 40 is completed, the pushing handle 231 of the pushing clamp 23 can be rotated upward, so that the pushing end 232 of the pushing clamp 23 can be moved away from the limiting member 22, and the tooling plate 21 can be driven to move away from the limiting member 22.

The tooling plate 21 is laterally slidably disposed on the base plate 10. The bottom plate 10 is provided with a second sliding groove, and the tooling plate 21 is arranged on the second sliding groove in a transverse sliding manner, so that the tooling plate 21 can be directionally displaced along the second sliding groove in the process of moving towards or away from the limiting part 22.
