Description

Technical Field

[0001] The utility model relates to the technical field of brakes, in particular to a circular ring fixing structure. Background Art

[0002] A tractor's brake is a device used to control the tractor's deceleration, stopping, or maintaining a stopped state. It is a vital component of the tractor and plays a crucial role in ensuring safety and stability during operation. To protect the internal components of the brake from external damage, the brake is often equipped with a brake housing. Several brake components are installed within the brake housing, so holes are drilled in the housing to facilitate the installation of these components. After drilling, the interior of the brake housing requires fine machining. During fine machining, it is fixed to prevent the brake housing from moving and causing inaccurate machining positions.

[0003] Most of the brake housing fixing tools currently used are to tighten the brake housing at the outer edge of the brake housing and then process it. After the brake housing is opened, it has a circular ring structure, and the outer wall is relatively thin. Pressing the outer edge for a long time may cause the ring to deform inward.

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] according to Figure 1-3 The utility model provides a circular ring fixing structure, including: a base 1, a convex plate 2, a pressing frame 3, and a baffle 4.

[0017] The cam 2 is arranged on the base 1. The pressing frame 3 is arranged on the base 1. The pressing frame 3 is arranged along the circumference of the cam 2. The pressing frame 3 also includes: a pressing plate 31. The pressing plate 31 is arranged on the side of the cam 2 away from the base 1. The pressing plate 31 can move relative to the base 1. The pressing frame 3 also includes: a chassis 32, a fixed column 33, and a fixed rod 34. One end of the chassis 32 is connected to the base 1, and the other end is connected to the fixed column 33. The fixed rod 34 is arranged on the fixed column 33. One end of the pressing plate 31 is rotatably arranged on the fixed rod 34. The pressing frame 3 also includes: a nut 35. The nut 35 is rotatably arranged on the fixed rod 34. The nut 35 is arranged on the side of the pressing plate 31 away from the fixed column 33. The fixed rod 34 is provided with a thread on the side away from the fixed column 33. The nut 35 corresponds to the thread.

[0018] When the brake housing needs to be fixed, first rotate the clamping plate 31 so that it moves toward the side of the fixing rod 34 away from the flange 2. Then align the center hole of the brake housing with the flange 2 so that the brake housing is placed on the flange 2 on the base 1, so that the brake housing is placed in the appropriate position. Then rotate the clamping plate 31 so that it rotates toward the side of the fixing rod 34 close to the brake housing, and rotates one side of the clamping plate 31 to the side of the brake housing away from the base 1. Then rotate the nut 35 so that the nut 35 moves toward the clamping plate 31, so that the clamping plate 31 presses the brake housing, completing the fixing of the brake housing. During fixing, the clamping plate 31 and the base 1 jointly apply a force to the brake housing to complete the clamping fixation. The pressure direction of the brake housing is along the solid part of the ring, and by applying force at both ends simultaneously, the force is shared, making it difficult to deform the brake housing when fixing it. During the fixing process, the brake housing can be quickly placed in a suitable position through the convex disc 2 corresponding to the brake housing, so as to facilitate subsequent adjustment of the fixing structure.

[0019] The chassis 32 is in a superior arc shape. One side of the chassis 32 plane faces the convex disc 2. The baffle 4 is arranged on the base 1. The baffle 4 is arranged on one side of the convex disc 2.

[0020] To ensure a more secure connection between the clamping frame 3 and the base 1, a larger-diameter chassis 32 is used. However, due to the larger diameter of the chassis 32, there is a risk of interference with the brake housing when it is placed onto the flange 2. The chassis 32 of the present invention is arched, with one flat side facing the flange 2. This ensures a sufficiently large contact area between the chassis 32 and the base 1 while maintaining a certain distance from the flange 2 to prevent interference. The brake housing is typically provided with lugs on its sides to facilitate installation on the tractor. The brake components within the brake housing vary in structure and are located in different locations, corresponding to the positions of the lugs. Therefore, different machining methods are required for different locations on the brake housing. The present invention includes a baffle 4. After the brake housing is placed onto the flange 2, the brake housing can be rotated in a certain direction, causing the lugs to rotate accordingly. The annular portion of the brake housing rotates without interfering with the baffle 4. However, the lugs, which are raised portions of the outer edge of the brake housing, have a larger rotation radius and can interfere with the baffle 4. During rotation, the lug can be brought into contact with the baffle 4 to fix the direction of the lug, that is, the brake housing is placed in a certain orientation, so that the position of each processing is fixed, which is conducive to repeated processing of multiple workpieces.

[0021] The working principle and use process of this utility model:

[0022] When the present invention is in use, the pressing plate 31 is first rotated so that the pressing plate 31 moves toward the side of the fixing rod 34 away from the convex disc 2, and then the center hole of the brake housing is aligned with the convex disc 2 so that the brake housing is sleeved on the convex disc 2 on the base 1, and then the brake housing is rotated in a certain direction so that the lug of the brake housing contacts the baffle 4. The pressing plate 31 is then rotated so that the pressing plate 31 rotates toward the side of the fixing rod 34 close to the brake housing, and one side of the pressing plate 31 rotates to the side of the brake housing away from the base 1, and then the nut 35 is rotated so that the nut 35 moves toward the pressing plate 31 so that the pressing plate 31 presses the brake housing, completing the fixation of the brake housing.

[0023] To sum up, the present invention uses a clamping frame. After the brake housing is placed on the base, the clamping plate of the clamping frame can clamp and fix the brake housing together with the base, and the direction of the fixed force is along the solid part of the brake housing to avoid the brake housing being deformed toward the hollow part due to the direction of the force along the hollow part.

[0024] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
