DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The utility model provides Figure 1-Figure 5 A quick tightening inner tie rod mechanism shown includes an assembly table 101, a clamping mechanism and a twisting mechanism. The inner tie rod product 102 is located in the clamping mechanism for clamping. An electric cylinder 501 is installed on the top of the assembly table 101. The electric cylinder 501 is used to drive the clamping mechanism to move. The clamping mechanism is driven to move by the operation of the electric cylinder 501, so that the twisting mechanism is connected to the clamping mechanism and drives the clamping mechanism to rotate, so that the clamped inner tie rod product 102 can be assembled on the steering gear housing.

[0026] In a preferred embodiment, the clamping mechanism includes a clamping seat 201, an inner pull rod product 102 is arranged inside the clamping seat 201, and a slide groove 202 is provided on both sides of the clamping seat 201. The inner wall of the slide groove 202 is slidably connected with a clamping block 203, and the top of the clamping block 203 is provided with an inclined waist groove 204. The inner wall of the inclined waist groove 204 is slidably provided with a bearing 205. A pushing mechanism is provided on both sides of the clamping seat 201. After the inner pull rod product 102 is placed in the clamping seat 201, the two bearings 205 are driven to move at the same time by the pushing mechanism, and the two clamping blocks 203 can move at the same time along the oblique guide of the inclined waist groove 204. The two clamping blocks 203 that move at the same time can clamp the inner pull rod product 102 in the center, ensuring that the inner pull rod product 102 can be stably aligned with the steering gear during assembly, thereby improving the stability of the assembly of the inner pull rod product 102.

[0027] Among them, the pushing mechanism includes a disc 206, which is arranged on the back of the clamping seat 201, and the front of the disc 206 is symmetrically fixedly connected with a movable rod 207, and the back of the clamping seat 201 is symmetrically opened with a movable hole 208. The outer wall of the movable rod 207 and the inner wall of the movable hole 208 are movably connected, and one end of the movable rod 207 is connected to the bottom end of the bearing 205. A reset mechanism is provided on the front of the disc 206, and a driving mechanism is provided on the back of the movable rod 207. By moving the disc 206, the two movable rods 207 can be moved, so that the two movable rods 207 can stably drive the bearing 205 to move. Since the bearing 205 rotates on the end of the movable rod 207, the mutual movement of the bearing 205 in the oblique waist groove 204 is smoother, thereby improving the smoothness of the operation of the clamping mechanism.

[0028] Among them, the reset mechanism includes a reset spring 209, which is arranged between the disc 206 and the clamping seat 201. The reset spring 209 is sleeved on the outer wall of the movable rod 207. When the disc 206 is no longer squeezed by the driving mechanism, the elastic action of the reset spring 209 causes the disc 206 to move backward and reset, thereby unlocking the clamping mechanism.

[0029] The driving mechanism includes a fixed seat 301, a sliding frame 302 is slidably provided on the outer wall of the fixed seat 301, a cylinder 307 is installed on the top of the fixed seat 301, the output end of the cylinder 307 is connected to the sliding frame 302, and both sides of the sliding frame 302 are fixedly connected with a connecting rod 303, and the end of the connecting rod 303 is rotatably provided with an extrusion roller 304, which squeezes the disc 206 and drives the disc 206 to move, and a slide 305 is fixedly connected to the bottom end of the sliding frame 302, and a guide rail 306 is fixedly connected to the top of the fixed seat 301. The slide 305 is slidably arranged on the guide rail. The top of the rail 306 allows the sliding frame 302 to move stably through the operation of the cylinder 307. When the sliding frame 302 moves, it can drive the two connecting rods 303 to move. The movement of the two connecting rods 303 can drive the squeezing roller 304 to move until the squeezing roller 304 squeezes the disc 206 to move the disc 206. Since the clamping mechanism needs to rotate for assembly, when the clamping mechanism rotates, the disc 206 will also rotate, which can cause the squeezing roller 304 to rotate, thereby reducing the friction between the disc 206 and the driving mechanism and ensuring the stable progress of the assembly work.

[0030] Among them, a floating seat 401 is provided at the top of the assembly table 101, and the screwing mechanism is arranged above the floating seat 401. The floating seat 401 is composed of multiple floating plates and springs. During assembly, due to the accumulated tolerance on the production line, the floating seat 401 provides floating amounts in the front, back, left and right directions. The springs are respectively arranged in the X, Y, and Z axes to provide floating, thereby offsetting the influence of tolerances.

[0031] Among them, the twisting mechanism is arranged above the assembly table 101, and the twisting mechanism is used to assemble the inner tie rod product 102 to the steering gear housing. The twisting mechanism includes a fixed frame 601, and a screw gun 602 is installed on the top of the fixed frame 601. The output end transmission of the screw gun 602 is provided with a connector 603. When the electric cylinder 501 moves to make the clamping mechanism move, a hole matching the connector 603 is opened on the back of the clamping mechanism, so that after the connector 603 is inserted into the hole, the screw gun 602 can be operated to drive the connector 603 to rotate, so that the clamping mechanism drives the inner tie rod product 102 to rotate for assembly.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
