However, there will be a certain damage rate during manufacturing, such as cracks and fine slits in the accessories. Therefore, each accessory needs to be detected after being produced to prevent potential safety risks during direct assembly in the later stage.

[0003] In the patent with the patent number CN220479463U, a sealing detection device for automobile motor accessories is disclosed, including a bottom plate and an air tightness detector. A wire is fixedly connected to the outer wall of the top of the air tightness detector, and the end of the wire away from the air tightness detector is fixedly connected to the outer wall of the bottom plate. A base is fixedly installed on the bottom surface of the bottom plate. Side plates are fixedly installed on the outer wall of the top of the bottom plate near both side walls. An outer shell is fixedly installed on the outer wall of the top of the two side plates. Four limiting rods are fixedly connected to the outer wall of the top of the bottom plate. A movable plate is sleeved outside the four limiting rods. A cylinder is installed on the bottom surface of the outer shell, and the bottom end of the cylinder is fixedly connected to the outer wall of the top of the movable plate. This utility model is convenient for workers to automatically collect motor shells with poor sealing performance for subsequent centralized processing, and through the setting of an extrusion mechanism, the sealing effect on the motor shell is better.

[0004] The above device has certain deficiencies when in use: when the above device is working, the motor accessories are detected by the air tightness detector, but there may be omissions for some fine cracks that the air tightness detector may not be able to directly detect, so secondary detection is still required to ensure no detection omissions.

[0005] Therefore, the utility model provides a sealing detection tooling for motor accessories to solve the above problems. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a sealing detection tooling for motor accessories, which solves the above problems.

[0008] The fixed component includes two connecting frames. Motors 1 are installed on the inner walls of both connecting frames. Connecting boxes are fixedly connected to the bottom walls of both connecting frames. The power shafts of the motors 1 all penetrate through the corresponding connecting boxes through bearings and are fixedly connected to bevel gears 1.

On both sides of the inner wall of the connecting box that are far away from each other, rotating shafts are rotatably installed. On the outer walls of the rotating shafts at the ends far away from each other, bevel gears 2 are fixedly connected. Threaded lines are opened on the outer parts of the rotating shafts. Sleeves are screwed and installed on the outer walls of the threaded lines. Limiting rods are fixedly connected to the top walls and bottom walls of the sleeves. Limiting grooves are opened on the top wall and bottom wall of the connecting box. The adjacent ends of the sleeves all slide through the connecting box and are fixedly connected to fixed cylinders. Sealing rings are installed on the inner walls of the fixed cylinders.

[0009] Through the above technical solution, the setting of the fixed component can clamp and fix the motor rotor and seal it, facilitating subsequent detection.

[0010] Furthermore, the two connecting frames are arranged symmetrically left and right. The top walls of both connecting frames are fixedly connected to the bottom wall of the moving component. The bevel gears 1 are all located in the inner cavities of the corresponding connecting boxes. The adjacent ends of the rotating shafts all penetrate through the corresponding mounting blocks through bearings and extend to the right side of the mounting blocks. The bevel gears 2 are all meshed and connected with the corresponding bevel gears 1.

[0011] Through the above technical solution, when the bevel gear 1 rotates, it drives the meshed bevel gear 2 to rotate.

[0012] Furthermore, the outer walls of the limiting rods all slide on the inner walls of the corresponding limiting grooves.

[0014] Furthermore, the moving component includes a U-shaped frame. The bottom walls of the U-shaped frame are all fixedly connected to the top wall of the detection table. A cross groove is opened on the top wall of the U-shaped frame. A bidirectional lead screw is rotatably installed in the inner wall of the cross groove.

[0015] Through the above technical solution, the bidirectional lead screw rotates in the inner wall of the cross groove, thereby driving the slider to move linearly.

[0016] Furthermore, sliders are screwed and installed on the left and right sides of the outer wall of the bidirectional lead screw. The outer walls of the sliders all slide on the inner wall of the cross groove.

[0017] Through the above technical solution, when the bidirectional lead screw moves, it drives the sliders to move away from or close to each other.

[0018] Further, connecting plates are fixedly connected to the bottom walls of the sliders, electric push rods are fixedly connected to the bottom walls of the connecting plates, and the movable ends of the electric push rods are fixedly connected to the top walls of the corresponding connecting frames.

[0019] Through the above technical solution, when the slider moves, it drives the connecting plate to move.

[0023] The utility model provides a sealing detection tooling for motor accessories. Compared with the prior art, it has the following beneficial effects:

[0024] (1). For the sealing detection tooling of the motor accessory, the electric push rod is used to push the connecting frame, connecting box, fixed cylinder and sealing ring to align with the two ends of the motor rotor. The second motor drives the bidirectional lead screw to rotate. The slider drives the connecting plate, electric push rod, connecting frame, connecting box and sealing ring to fit the motor rotor. The first motor drives the first bevel gear, second bevel gear and rotating shaft to rotate inside the inner wall of the mounting block. The rotating shaft drives the sleeve to slide outward along the outer wall of the thread. The sleeve drives the limiting rod to slide along the inner wall of the limiting groove. The sleeve pushes the fixed cylinder and sealing ring to clamp and fix the motor rotor for sealing. The sealing detector controls its air pipe to convey gas into the motor rotor to detect the sealing performance of the motor rotor. The electric push rod pushes the connecting frame, connecting box and motor rotor into the wading detection frame, and injects water into the wading detection frame to check whether there are bubbles discharged, so that when detecting the sealing performance of the motor accessory electronic rotor, it can be double-detected to prevent the situation of missed detection due to fine cracks, affecting the detection effect of the motor rotor, and avoiding the assembly of defective accessories affecting the quality of the motor.
