Description

Technical Field

[0001] The utility model relates to the technical field of O-ring processing, and specifically relates to a fixture for an O-ring of a new energy motor. Background Technique

[0002] An electric vehicle refers to a vehicle powered by an on-vehicle power source and driven by an electric motor to drive the wheels, meeting the requirements of road traffic and safety regulations. Since its environmental impact is relatively smaller than that of traditional vehicles, its future is widely optimistic. Among the core components of new energy vehicles, there are three mainstream motor types, including DC motors, asynchronous motors, and permanent magnet synchronous motors;

[0003] The main functions of the O-ring seal of the motor are: 1. Prevent water ingress; 2. Prevent foreign matters such as dust from entering; 3. Prevent lubricating oil leakage. When processing the existing O-ring seals, the outer side of the formed seals needs to be deburred and polished, so fixtures are required to clamp and fix the O-rings.

[0004] Chinese Utility Model Publication No.: CN217019726U includes a workbench, and support legs are fixedly connected to the lower end of the workbench. A seal ring body is arranged inside the clamping mechanism. The utility model provides an electric slide rail, an electric slider, a first motor, and a clamping mechanism. The seal ring is sleeved outside the clamping mechanism, and then the movable block and the support block are driven to move through the transmission of the second motor and the lead screw. After moving to a suitable position according to the diameter of the seal ring, the seal ring is clamped inside the limit groove, realizing the clamping and fixing of the seal ring. At the same time, it can adapt to seal rings of different diameters for clamping, and four seal rings can be clamped at one time for processing, improving efficiency. At the same time, the clamping mechanism can be driven to rotate through the first motor, the electric slide rail, and the electric slider at the bottom, which is convenient for deburring and polishing the outer side of the seal ring, convenient for operation, and greatly improves the practicability.

[0005] The applicant found that there are some deficiencies in the use of this patent: during the grinding process, debris will be generated, and the debris will fall into the sliding opening and adhere to the surface of the lead screw. After more debris adheres, it will affect the transmission of the lead screw and the threaded block, and may cause a jamming situation, affecting the stability of the fixture.

[0006] Therefore, the utility model designs a fixture for an O-ring of a new energy motor to solve the problems existing in the prior art. Content of the Utility Model

[0007] The purpose of the utility model is to provide a fixture for an O-ring of a new energy motor to solve the problems raised in the above background technique.

[0008] To achieve the above object, the present utility model provides the following technical solutions: A new energy motor O-ring fixture, comprising: a base, a round box is provided above the base, four clamping blocks are provided above the round box, a plurality of arc-shaped grooves are opened on the outer side of the clamping blocks, a driving mechanism for preventing jamming is provided on the round box, a U-shaped frame is installed on the top of the base, and a rotating mechanism is provided on the U-shaped frame.

[0009] Preferably, the driving mechanism includes a rotating shaft rotatably installed at the upper and lower ends of the round box. A driving gear is installed on the lower outer side wall of the rotating shaft. A support fixed to the bottom inner wall of the round box is provided around the driving gear. A lead screw is rotatably installed on the support. One end of the lead screw is installed with a driven gear meshing with the driving gear. The outer side wall of the other end of the lead screw is slidably installed with a square sleeve through a thread. A limiting groove slidably connected with the square sleeve is opened on the side wall of the round box. A vertical rod is installed at the top of the square sleeve away from the driving gear. The top of the vertical rod is fixedly installed with the bottom of the clamping block. Reverse rotation of the rotating shaft causes the driving gear to rotate, which can cause the four driven gears to rotate, synchronously rotate the four lead screws, make the square sleeve slide in the limiting groove and contract into the round box, so that the four clamping blocks approach each other to release the fixation of the O-ring. The lead screw is located inside the round box, which can prevent debris from adhering to its surface, avoid jamming between the lead screw and the square sleeve, and improve the stability of the fixture.

[0010] Preferably, a knob is installed at the top of the rotating shaft. The knob facilitates the staff to rotate the rotating shaft.

[0011] Preferably, the rotating mechanism includes a servo motor. The servo motor is fixedly installed on the top inner wall of the U-shaped frame. The output end of the servo motor is connected to the center of the bottom of the round box. The servo motor drives the round box to rotate, which can make the O-ring rotate, facilitating the staff to polish different positions of the O-ring while standing in place.

[0012] Preferably, a plurality of rotating rods are provided around the bottom of the round box. The bottom of the rotating rod is installed with a universal wheel that rolls on the top of the base. When the round box rotates, it drives the rotating rod to rotate, making the universal wheel roll on the base, which can reduce the friction of the round box rotation.

[0013] Preferably, anti-slip protrusions are provided on the surface of the arc-shaped groove. The anti-slip protrusions can increase the friction between the clamping block and the O-ring and improve the clamping and fixing effect.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By setting the circular box and the driving mechanism in the utility model, when the rotating shaft is rotated to make the driving gear rotate, the four driven gears can drive the four lead screws to rotate synchronously, so that the four square sleeves extend, and then the four clamping blocks can be driven to clamp the O-ring. Since the lead screws are arranged in the circular box, the situation that the debris generated by grinding adheres to the surface of the lead screws is avoided, thereby avoiding the situation that the transmission between the lead screws and the square sleeves is stuck, and making the fixture more stable during use;

[0016] 2. By setting the rotating mechanism in the utility model, the servo motor drives the circular box to rotate, which can adjust the position of the O-ring, facilitating the staff to grind different positions of the O-ring in place, and improving the practicability.

[0027] Working principle: The O-ring is sleeved outside the clamping block 3. Then, the knob 509 is rotated to make the driving gear 502 rotate. The driving gear 502 drives the four driven gears 505 to rotate, so that the lead screw 504 rotates, driving the square sleeve 506 to slide outwards in the limiting groove 507, making the four clamping blocks 3 move away from each other. The O-ring can be tightly clamped through the arc-shaped groove 4. Then, the staff can hold the grinding machine to grind the seal ring. Through the protection of the circular box 2 for the lead screw 504, it can be avoided that debris adheres to the lead screw 504 during grinding, and the situation of jamming in the transmission between the square sleeve 506 and the lead screw 504 is avoided, improving the stability of the fixture. The servo motor 701 drives the circular box 2 to rotate, enabling the circular box 2 to rotate, so that the seal ring can rotate to adjust the grinding position.
