Description
Technical Field
[0001] This utility model relates to the field of gearbox housing technology, and in particular to a gearbox housing grinding device. Background Technology
[0002] The gearbox housing is a key load-bearing component of the gearbox, acting like a sturdy "armor" to protect the internal gears, shafts, and other precision parts. It is usually made of high-strength metal materials by casting or forging, possessing good rigidity and toughness to withstand the complex forces and heat loads generated during gearbox operation. Its precise structural design includes multiple mounting holes and oil passages to ensure accurate assembly with other components and to guarantee the flow of lubricating oil. It plays an indispensable role in the stable operation of the gearbox and extending its service life. In the existing working environment, the gearbox housing is polished by relying solely on two opposing rectangular clamping blocks. This clamping method has obvious defects. Due to the limited contact area between the clamping blocks and the housing, the clamping force is unevenly distributed. Under the action of polishing force, the housing is prone to shaking. The shaking causes the polishing position to shift and the force to become uncontrollable, resulting in problems such as uneven polishing marks, local over-polishing or under-polishing on the housing surface. This seriously affects the polishing quality and efficiency. Therefore, this utility model proposes a gearbox housing polishing device to solve the above problems. Utility Model Content
[0003] To address the aforementioned problems, this utility model proposes a gearbox housing grinding device to solve the issues in the prior art where gearbox housing grinding relies on clamping with two rectangular blocks, resulting in a small contact surface, uneven force, and easy shaking, leading to misalignment of the grinding position and loss of force control, which seriously affects quality and efficiency.
[0004] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a gearbox housing grinding device, including a base, a support plate and a drive rod. The support plate is fixedly connected to the top of the base, a drive mechanism is provided on one side of the base, drive rods are symmetrically installed on both sides of the drive mechanism, a clamping arm is fixedly connected to one side of the drive rod, and clamping mechanisms are symmetrically provided at both ends of the clamping arm.
[0005] A further improvement is that the clamping mechanism includes a rotating rod, a rotating clip, a pad, and a fastening screw. The top and bottom ends of the clamping arm are symmetrically provided with collars. The rotating rod is hinged inside the collar. One end of the rotating rod is hinged to a rotating clip. The two ends of the rotating clip are fixedly connected to pads. One end of the collar is threadedly connected to a fastening screw.
[0006] A further improvement is that the position of the rotating rod and the collar are parallel to each other, and one end of the fastening screw is in contact with one side of the rotating rod.
[0007] A further improvement is that the rotating card has an L-shaped structure, one side of the pad is attached to the outside of the shell, and the pad is made of rubber.
[0008] A further improvement is made in that: the driving mechanism includes a fixed frame, a bidirectional lead screw, a rotary motor, and a limiting rod. The top of the fixed frame is rotatably connected to the bidirectional lead screw, and a rotary motor is fixedly installed on one side of the fixed frame. The output end of the rotary motor is fixedly connected to one end of the bidirectional lead screw. A limiting rod is fixedly connected to the top of the fixed frame. The bottom ends of the two driving rods are slidably connected to the two ends of the limiting rod, respectively. The two ends of the bidirectional lead screw pass through the bottom ends of the two driving rods and are threadedly connected to them.
[0009] A further improvement is that: a set of short support blocks and a set of long support blocks are symmetrically fixedly connected to both sides of the support plate, and the two sets of short support blocks and long support blocks are respectively attached to both ends of the gearbox housing. A positioning rod is fixedly connected to the top of the support plate, and the top end of the positioning rod extends through the top of the gearbox housing.
[0010] A further improvement is that: the top of the base is fixedly connected to multiple reinforcing plates, the reinforcing plates are rectangular in shape, and the top of the reinforcing plates are fixedly connected to the bottom of the support plate.
[0011] The beneficial effects of this utility model are as follows: The output end of the rotary motor rotates in both directions, which can drive the two drive rods to move simultaneously in different directions. This causes the two drive rods to bring the two clamping arms closer together, so that the rotating rods at the top and bottom of the two clamping arms fit against the sides of the gearbox housing. Then, by tightening one end of the fastening screw, the rotating rods are pressed tightly. The rubber pad on the rotating clamp automatically deforms and fits the shape of the gearbox housing, making the rotating clamp hold the gearbox housing more securely. This solves the problem in the prior art where the gearbox housing is polished by clamping with two rectangular clamping blocks, which results in a small contact area, uneven force, easy shaking, and misalignment of the polishing position and loss of force control, seriously affecting quality and efficiency.

Detailed Implementation
[0014] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.
[0015] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a gearbox housing grinding device, including a base 1, a support plate 2, and drive rods 3. The support plate 2 is fixedly connected to the top of the base 1. A drive mechanism is provided on one side of the base 1, and drive rods 3 are symmetrically installed on both sides of the drive mechanism. A clamping arm 4 is fixedly connected to one side of the drive rod 3, and clamping mechanisms are symmetrically provided at both ends of the clamping arm 4. The gearbox housing is placed on the top of the support plate 2, and the gearbox housing is supported by the support plate 2. The drive mechanism can drive the two drive rods 3 to move closer to each other. The drive rods 3 drive the clamping mechanisms through the clamping arms 4 to clamp the two sides of the gearbox housing, thereby locking the position of the gearbox housing and preventing the gearbox housing from vibrating during grinding, which would affect the grinding effect.
[0016] The clamping mechanism includes a rotating rod 5, a rotating clip 6, a pad 7, and a fastening screw 8. The driving mechanism includes a fixed frame 9, a bidirectional lead screw 10, a rotary motor 11, and a limiting rod 12. The top of the fixed frame 9 is rotatably connected to the bidirectional lead screw 10. The rotary motor 11 is fixedly installed on one side of the fixed frame 9. The output end of the rotary motor 11 is fixedly connected to one end of the bidirectional lead screw 10. The top of the fixed frame 9 is fixedly connected to the limiting rod 12. The bottom ends of the two driving rods 3 are slidably connected to the two ends of the limiting rod 12, respectively. The two bidirectional lead screws 10... The ends of the two drive rods 3 are respectively threaded through and connected to the bottom ends of the two drive rods 3. The limiting rod 12 restricts the movement trajectory of the two drive rods 3. The two ends of the bidirectional lead screw 10 are respectively threaded to the bottom ends of the two drive rods 3. The output end of the rotary motor 11 rotates in both directions, which can drive the two drive rods 3 to move in different directions at the same time, so that the two drive rods 3 drive the two clamping arms 4 to move closer to each other or further away from each other. That is, the clamping arms 4 drive the rotating rod 5 to move closer to the gearbox housing to clamp and lock it in position, or the clamping arms 4 drive the rotating rod 5 away from the gearbox housing to release the lock.
[0017] The clamping mechanism includes a rotating rod 5, a rotating clip 6, a pad 7, and a fastening screw 8. The top and bottom ends of the clamping arms 4 are symmetrically provided with collars. The rotating rod 5 is hinged inside the collars. One end of the rotating rod 5 is hinged to the rotating clip 6. The two ends of the rotating clip 6 are fixedly connected to the pads 7. One end of the collar is threadedly connected to the fastening screw 8. The rotating rod 5 and the collar are parallel to each other. One end of the fastening screw 8 is in contact with one side of the rotating rod 5. The rotating clip 6 has an L-shaped structure. One side of the pad 7 is in contact with the outer side of the housing. The pad 7 is made of rubber. The drive rod 3 drives the two clamping arms 4 to move closer to both sides of the gearbox housing, so that the rotating rods 5 at the top and bottom ends of the two clamping arms 4 are in contact with both sides of the gearbox housing. Then, one end of the fastening screw 8 is tightened to press the rotating rod 5. The rubber pad 7 on the rotating clip 6 automatically deforms and fits the shape of the gearbox housing, making the rotating clip 6 clamp the gearbox housing more securely.
[0018] A set of short support blocks 13 and a set of long support blocks 15 are symmetrically fixed to both sides of the support plate 2. The two sets of short support blocks 13 and long support blocks 15 are respectively attached to both ends of the gearbox housing. A positioning rod 16 is fixedly connected to the top of the support plate 2, with its tip extending through the top of the gearbox housing. The two sets of short support blocks 13 and long support blocks 15 are respectively attached to both ends of the gearbox housing, and the positioning rod 16 extends through the interior of the gearbox housing. The short support blocks 13, long support blocks 15, and positioning rod 16 provide support to both ends and the interior of the gearbox housing, improving the stability of the gearbox housing during polishing.
[0019] The top of the base 1 is fixedly connected with a plurality of reinforcing plates 14. The reinforcing plates 14 are rectangular in shape. The top of the reinforcing plates 14 are fixedly connected to the bottom of the support plate 2. The reinforcing plates 14 are fixed between the base 1 and the support plate 2, thereby strengthening the connection between the support plate 2 and the base 1 and enhancing the support capacity of the base 1 for the support plate 2.
[0020] The gearbox housing grinding device has a rotary motor 11 whose output end rotates in both directions, which can drive two drive rods 3 to move simultaneously in different directions. This causes the two drive rods 3 to bring the two clamping arms 4 closer together, so that the rotating rods 5 at the top and bottom of the two clamping arms 4 fit against the sides of the gearbox housing. Then, one end of the fastening screw 8 is tightened to press the rotating rods 5 against the gearbox housing. The rubber pads 7 on the rotating clip 6 automatically deform and fit the shape of the gearbox housing, making the rotating clip 6 clamp the gearbox housing more securely.
