Description

Technical Field

[0001] The utility model belongs to the technical field of positioning tooling, and in particular relates to a tooling for detecting and positioning a gear shifting seat of a knife sharpener. Background Art

[0002] The gear seat is one of the core components of the knife sharpener. The sharpened blade is on a straight line. Compared with manual sharpening, it increases the blade's strength of use, and increases the blade's service life and processing capacity.

[0003] After the gear shift seat is processed, it is necessary to perform various inspections on the gear shift seat, such as using a CCD camera to inspect the appearance of the gear shift seat. During the inspection, in order to ensure the accuracy of the position of the gear shift seat, a positioning tool is usually used to position the gear shift seat.

[0004] In the prior art, a fixture with a more complex structure is usually used for positioning. For example, the Chinese utility model patent "A gear shift seat processing and testing equipment for a knife grinder" with authorization announcement number CN219649709U, through the coordinated use of the first guide groove, the second guide groove, the first bidirectional threaded rod, the second bidirectional threaded rod, the first movable plate and the second movable plate, makes it easy to adjust the position of the clamping plate, and the staff can fix the workpiece that exceeds the size of the support plate, so that the workpiece clamping mechanism can be changed according to the size of the fixing mechanism. When the workpiece of the gear shift seat is being processed and tested, a workpiece larger than the support plate can be placed, thereby avoiding the limitation that the workpiece of the gear shift seat cannot be placed with a size larger than the support plate.

[0005] Although the positioning fixtures of the prior art including the above-mentioned ones can ensure the stability of the clamping of the gear shift seat, they are relatively complex in structure and require additional power consumption, which is costly for batch testing work. For conventional testing work, it is not necessary to make the gear shift seat too fixed.

[0006] In order to solve the above problems, the present application proposes a tool for detecting and positioning a gear seat of a knife sharpener. Utility Model Content

The second internal positioning block 42 is embedded in the second assembly cavity 411 to form a telescopic structure. The third countersunk screw 45 is screwed into the second internally threaded countersunk hole 413 by threaded engagement. For gear shift seat bodies 1 of different sizes, the third countersunk screw 45 can be loosened, and then the position of the second internal positioning block 42 can be adjusted so that the head end of the second internal positioning block 42 is against the needle. Finally, the third countersunk screw 45 is tightened to lock the second internal positioning block 42. No further adjustment is required for subsequent inspections of the gear shift seat bodies 1 of the same batch.

It can be seen from the figure that the needle positioning block 4 presses against the corner of the needle and the connection node between the needle and the gear shift seat body 1, and the positioning effect is good and the stability is high.

[0052] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, the outer wall of the second inner positioning block 42 abuts against the inner wall of the second assembly cavity 411 , thereby improving the stability of the combination of the second outer positioning block 41 and the second inner positioning block 42 .
