This device solves the problem that after the machining of automotive differential half-shaft gears, it is necessary to inspect the outer diameter and runout dimensions. The conventional inspection method is manual inspection, which is inefficient and often cannot meet production requirements.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic detection device for differential half-shaft gears, comprising a worktable and a gear.

The slider is slidably connected inside the movable groove and threaded onto the rod wall of the lead screw, thereby facilitating the movement of the position of the linear displacement sensor.
[0007] Preferably, the bottom surface of the linear displacement sensor is located on the bottom surface of the L-shaped plate, which facilitates the linear displacement sensor to detect the gear.
[0008] Preferably, the two compression bolts are of equal length and can rotate independently, which facilitates the adjustment of the placement position of the gear and the complete inspection of gears of different sizes.
[0009] Preferably, the length of the L-shaped plate is less than the length of the fixed plate, thereby facilitating the effective movement of the L-shaped plate on the fixed plate.

A mounting bracket 6 is fixedly installed on the upper end of the workbench 2. A fixing plate 8 is fixedly installed on the front side wall of the mounting bracket 6. An L-shaped plate 7 is slidably connected to the front side wall of the fixing plate 8. A linear displacement sensor 5 is fixedly installed on the front side wall of the L-shaped plate 7. A fixed seat 3 is rotatably connected inside the top surface of the workbench 2. A rotary motor 1 is fixedly installed inside the workbench 2. The output shaft of the rotary motor 1 is fixedly connected to the bottom surface of the fixed seat 3 through the interior of the top surface of the workbench 2. The gear 4 is placed inside the fixed seat 3. Both ends of the fixed seat 3 are threaded with clamping bolts 13. 13 are pressed against the side wall of gear 4 through the interior of fixed base 3. Linear displacement sensor 5 is set directly above fixed base 3. The bottom surface of linear displacement sensor 5 is at the bottom surface of L-shaped plate 7. The length of L-shaped plate 7 is less than the length of fixed plate 8. The top of fixed plate 8 is higher than the top of mounting bracket 6. Mounting bracket 6 is U-shaped. When testing gear 4, first place gear 4 inside fixed base 3. Then rotate the pressing bolts 13 on both sides to press the side wall of gear 4. When testing, turn on rotary motor 1 to rotate fixed base 3. Then use linear position sensor 5 to perform a comprehensive test on gear 4. Example 2
[0020] To facilitate the easy installation and rotation of gear 4, in this embodiment, as follows: Figure 1-3 As shown, a movable groove 10 is provided inside the front side wall of the fixed plate 8. A lead screw 11 is rotatably connected inside the movable groove 10. A reciprocating motor 9 is fixedly installed at the upper end of the fixed plate 8.

The two clamping bolts 13 are of equal length and can rotate independently. During the detection work, the position of the linear displacement sensor 5 is moved according to the position of the top surface of the gear 4. The reciprocating motor 9 is turned on, causing the lead screw 11 to rotate, which can easily drive the position of the L-shaped plate 7 to move, making it convenient for the linear displacement sensor 5 to detect the placed gear 4.
[0021] It should be noted that in this embodiment, when using the automatic detection equipment for differential half-shaft gears, such as... Figure 1-3As shown, when testing gear 4, gear 4 is first placed inside the fixed base 3. Then, the clamping bolts 13 on both sides are rotated to clamp the side wall of gear 4. During the testing, the position of linear displacement sensor 5 is moved according to the position of the top surface of gear 4. The reciprocating motor 9 is turned on to rotate the lead screw 11, which can easily move the L-shaped plate 7 to facilitate the linear displacement sensor 5 to test the placed gear 4. Then, the rotary motor 1 is turned on to rotate the fixed base 3. Finally, the linear position sensor 5 is used to perform a comprehensive test on gear 4.
