DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: a steering gear housing movable fixed seat, including a fixed frame 1 and a transmission belt 12, a movable seat 3 is arranged at the left end of the inner top of the fixed frame 1, a placing table 4 is fixedly connected to the middle of the top of the movable seat 3, a cavity 5 is opened inside the movable seat 3, a micro motor 6 is fixedly connected to the left end of the inner bottom of the cavity 5, a first rotating rod 7 is fixedly connected to the output end of the micro motor 6, the top of the first rotating rod 7 penetrates the movable seat 3 and is fixedly connected to the clamping movable seat 8, the right end of the inner bottom of the cavity 5 is rotatably connected to the second rotating rod 9, the top of the second rotating rod 9 penetrates the movable seat 3 and is fixedly connected to the positioning movable seat 10 , the first rotating rod 7 and the second rotating rod 9 are fixedly connected to the pulley 11 at the middle and upper parts of the outer sides, and the two pulleys 11 are connected by a transmission belt 12. An open groove 13 is opened on the top front side of the movable seat 3, and a bidirectional screw rod 14 is rotatably connected to the left side of the movable seat 3. The right end of the bidirectional screw rod 14 passes through the open groove 13. The left and right sides of the outer wall of the bidirectional screw rod 14 are threadedly connected with movable blocks 15. The top of the movable block 15 is fixedly connected with a limiting rod 16. The front and rear sides of the movable seat 3 are provided with a disassembly mechanism 2. The height of the clamping movable seat 8 is greater than the height of the positioning movable seat 10. The two movable blocks 15 are both slidably connected to the inside of the open groove 13;

[0040] Specifically, the first rotating rod 7 can be driven to rotate by the micro motor 6, thereby driving the outer pulley 11 to rotate. This rotation action is transmitted to the pulley 11 on the second rotating rod 9 through the transmission belt 12, so that the clamping movable seat 8 and the positioning movable seat 10 rotate synchronously. When the positioning block on the positioning movable seat 10 contacts the steering gear housing, it will stop rotating. At this time, one end of the steering gear housing has been limited and fixed. The cleverness of this design lies in that the initial fixation of the steering gear housing is achieved through simple mechanical transmission, which not only ensures the stability during processing, but also improves production efficiency. Subsequently, by rotating the bidirectional screw 14, the movable blocks 15 on both sides can be driven to move toward the middle. In this process, the limit rod 16 will follow the movement of the movable block 15 to limit and clamp the other end of the steering gear housing. This bidirectional clamping method not only improves the stability of the steering gear housing, but also can effectively prevent it from shaking or deflecting during the transportation process, thereby greatly improving the processing efficiency of the steering gear housing.

One end of the second spring 208 is fixedly connected to the limit column 209. The disassembly mechanism 2 also includes a handle 210, which is fixedly connected to the middle of the left side of the moving seat 3. The sizes of the two limit blocks 205 match the corresponding internal sizes of the slide groove 201 respectively;

[0042] Specifically, when the mobile seat 3 needs to be replaced, the movable rod 204 is moved outward at this time, and the limit block 205 will be separated from the slide groove 201, and the second spring 208 will release the force that was squeezed before, driving the limit column 209 to pop out. This step is designed to prevent the limit block 205 from rebounding during the disassembly process, thereby affecting the subsequent disassembly work, and then the mobile seat 3 is easily removed from the slide groove 201 through the handle 210. When the new mobile seat 3 is installed, it needs to be fixed again. At this time, the limit column 209 is pressed, and the second spring 208 is squeezed to drive the limit column 209 into the hole 207. Subsequently, the first spring 206 will release the force that was squeezed before, driving the limit block 205 into the slide groove 201. This step is designed to prevent the mobile seat 3 from accidentally falling off during use, which increases the safety and stability of the equipment. In summary, this ingenious mechanical structure design makes the disassembly and replacement of the mobile seat 3 very simple and convenient. It not only improves the practicality of the equipment, but also reduces maintenance costs and time.

At this time, the clamping movable seat 8 and the positioning movable seat 10 will rotate accordingly until the positioning block on the positioning movable seat 10 contacts the steering gear housing. One end of the steering gear housing can be limited and fixed, and then the two-way screw rod 14 is rotated to drive the movable blocks 15 on both sides to move toward the middle, and the limiting rod 16 will move with it to limit and clamp the other end of the steering gear housing. During the conveying process, the steering gear housing is not easy to shake and deviate, thereby improving the processing efficiency of the steering gear housing and the quality of subsequent product processing, which can meet the needs of users. At this time, the servo motor 18 can drive the conveying roller 17 to rotate, so that it drives the movable seat 3 in the slide groove 201 The movable rod 204 is moved outwardly, and the limit block 205 is separated from the slide groove 201. At this time, the second spring 208 releases the squeezed force and drives the limit column 209 to pop out, which can prevent the limit block 205 from rebounding and affecting the subsequent disassembly work. Then, the movable seat 3 can be removed from the slide groove 201 by the handle 210, and then the new movable seat 3 can be installed. At this time, the limit column 209 is pressed again, and the second spring 208 is squeezed to drive the limit column 209 to enter the hole 207, and then the first spring 206 releases the squeezed force and drives the limit block 205 to enter the slide groove 201, which can prevent the movable seat 3 from accidentally falling off.
