[0021] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0022] Reference Figures 1 to 3As shown, the device for detecting the perpendicularity of combined gears in this embodiment includes a base plate 1, a fixed seat 2, a movable seat 3, and a quick clamp 4. The fixed seat 2 is mounted on the base plate 1. The quick clamp 4 includes a base, a telescopic rod, a connecting rod, and a handle. The base is mounted on the base plate 1. One end of the handle is a handheld operating end, and the other end is hinged to the base and connected to one end of the connecting rod. The other end of the connecting rod is connected to one end of the telescopic rod, and the other end of the telescopic rod is threaded to the movable seat 3. The movable seat 3 is directly opposite the fixed seat 2. Opposite V-shaped grooves are opened on the opposite surfaces of the movable seat 3 and the fixed seat 2. The combined gear to be tested is clamped between the movable seat 3 and the fixed seat 2.

[0023] The fixed base 2 is L-shaped, comprising a horizontal plate and a vertical plate. The horizontal plate is fixed to the base plate 1 by two hexagonal socket screws 10. A V-shaped groove is provided on the outer side of the vertical plate. Two guide posts 9 are fixedly mounted on the horizontal plate, and the movable base 3 passes through the two guide posts 9. Two first guide holes are provided on the movable base 3, and the ends of the guide posts 9 extending out of the fixed base 2 extend into the first guide holes. The two first guide holes are located on both sides of the V-shaped groove on the movable base 3.

[0024] A bracket is installed on the base of the quick clamp 4, and a second guide hole is opened on the bracket, through which the telescopic rod passes.

[0025] The other end of the telescopic rod is threaded, and a nut is installed on the threaded section.

[0026] A pad 6 is placed between the base and the base plate 1, and several hex socket screws 5 fix the base and the pad 6 to the base plate 1.

[0027] A dial indicator 7 is installed on one side of the base plate 1, and a dial indicator 8 is installed on the dial indicator 7. The dial indicator 8 is located on one side of the gap between the fixed base 2 and the movable base 3.

[0028] During the perpendicularity test of the combined gear, the threaded end of the telescopic rod of the quick clamp 4 connects to the central threaded hole of the movable seat 3. The guide post 9 passes through the fixed seat 2 and the movable seat 3 in sequence. By turning the handle, the fixed seat 2 and the movable seat 3 clamp the combined gear. Further tightening the nut ensures that the clamping force between the two V-grooves meets the requirements. When changing products, only the handle of the quick clamp 4 needs to be moved to replace the product.

[0029] The function of the pad 6 is to adjust the height of the fixed seat 2 and the movable seat [3] so that the height of the two is consistent, so that the guide post 9 can pass through the holes of the two parts flexibly, making the translation mechanism of the entire device flexible.

[0030] As can be seen from the above technical solution, this utility model has the following significant features: (1) By designing V-shaped clamps, it is convenient to quickly position and clamp gear shafts of different diameters.

[0031] (2) Using quick clamps, it is possible to easily change combination gears of different diameters.

[0032] (3) By adjusting the length of the screw extending from the front end of the telescopic rod, the extension distance of the movable seat is ensured, thereby achieving the clamping of combined gears of different diameters.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
