[0017] Reference Figures 1 to 5 The present invention will be further described below.

[0018] A toothed rotating shaft inspection fixture includes a base 1, on which a first inspection component 2, a second inspection component 3, and a third inspection component 4 are disposed. The first inspection component 2 includes a positioning block 5, a plurality of inspection push blocks 6, and a quick clamping component 7. The inspection push blocks 6 are provided with inspection grooves and are slidably connected to the base 1. The second inspection component 3 includes a tooth inspection block 8, on which a tooth inspection through hole 18 and a tooth inspection stop hole 19 are provided. The third inspection component 4 includes a plurality of annular groove inspection blocks 9, on which annular groove through grooves 10 and annular groove stop grooves 11 are provided.

[0019] like Figures 1 to 5 As shown, when inspecting parts, the parts are placed on the first inspection component 2, the second inspection component 3, and the third inspection component 4 respectively for inspection, and the inspection order can be changed:

[0020] When inspecting on the first inspection component 2, the part is first positioned by the positioning block 5, and then the part is clamped on the positioning block 5 by the quick clamp component 7. Then, the shaft on the part is inspected in sequence by the two inspection push blocks 6 to inspect the positional relationship between the shaft and the connecting part, the shaft diameter, and the distance and parallelism between the two relative planes on the shaft, etc.

[0021] When inspecting on the second inspection component 3, the part is held vertically so that the teeth on its shaft are aligned with the tooth inspection through hole 18 and the tooth inspection stop hole 19 on the tooth inspection block 8 in order to inspect the various dimensions of the teeth.

[0022] When inspecting on the third inspection component 4, the part is placed horizontally, and the annular groove on the part is inspected for its size by passing through the annular groove through groove 10 and the annular groove stop groove 11 on the annular groove inspection block 9.

[0023] The aforementioned inspection fixture integrates the inspection of parts onto the same base 1, simplifying the inspection process, making inspection more convenient, effectively reducing misjudgments and measurement errors during inspection, and lowering inspection costs.

[0024] like Figure 1As shown, specifically, there are two detection push blocks 6, with detection grooves in the form of through holes and U-shaped grooves, respectively. The detection groove in the form of through holes is coaxial with the part shaft, while the detection groove in the form of U-shaped grooves is perpendicular to the part shaft.

[0025] like Figure 4 As shown, specifically, the annular groove through groove 10 and the annular groove stop groove 11 on the same annular groove detection block 9 are connected vertically, with the annular groove through groove 10 at the top and the annular groove stop groove 11 at the bottom, mainly used to detect the width of the annular groove.

[0026] Specifically, the quick clamp assembly 7 includes a fixed seat located on the base 1, a pressure rod is lifted and connected to the fixed seat, a connecting rod is hinged to the pressure rod, a handle is hinged to the connecting rod, and the handle is also hinged to the fixed seat. The pressure rod, the connecting rod and the handle form a crank-slider mechanism to clamp the parts.

[0027] Specifically, the end of the pressure bar is equipped with an elastic pressure block to prevent damage to the surface of the parts when pressing them.

[0028] like Figure 2 As shown in this example, preferably, the positioning block 5 is provided with a placement groove 12, and the placement groove 12 is surrounded by a positioning plate 13, a number of side positioning blocks 14 and a number of hole positioning blocks 15. The positioning plate 13 is provided with a slot corresponding to the product ring groove.

[0029] Specifically, the placement slot 12 places the part and supports the connector of the part. Then, the connector of the part is fully positioned by the positioning plate 13, the side positioning block 14 and the hole positioning block 15.

[0030] like Figure 1 As shown in this example, preferably, the base 1 is provided with a fixed insert 17 corresponding to the detection push block 6, and the detection push block 6 is slidably connected to the fixed insert 17 to ensure the accuracy of the movement of the detection push block 6 and improve the detection accuracy.

[0031] like Figure 3 As shown in this example, preferably, the tooth detection block 8 is provided with a limiting groove 20 corresponding to the tooth detection through hole 18 and the tooth detection stop hole 19. When detecting the teeth on the shaft of the part, the connecting part on the part is placed into the limiting groove 20 for positioning, so that the teeth on the shaft are quickly aligned with the tooth detection through hole 18 and the tooth detection stop hole 19, thereby improving the detection efficiency.
