[0001] This utility model belongs to the field of riveting and positioning technology, specifically, it relates to a bracket riveting and positioning assembly for pulley press riveting. Background Technology

[0002] In the field of pulley manufacturing, such as automotive window regulators, luggage, sliding doors and door hangers, the riveting connection between pulleys and brackets is a key process that determines product performance. The relative positional accuracy of pulleys and brackets during riveting directly affects the smoothness of movement, structural stability and service life of the product after assembly.

[0003] When riveting, the pulley and bracket need to be installed in the corresponding grooves on the base, and then the base is installed on the external riveting equipment. However, when installing the base, it is usually installed on the riveting equipment with multiple bolts. This is cumbersome during the disassembly and assembly process, and it is not convenient for workers to operate, thus reducing the efficiency of the riveting work.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the technical problem that during riveting, pulleys and brackets need to be installed in corresponding grooves on the base before the base is mounted on external riveting equipment, but the installation of the base usually involves using multiple bolts, which is cumbersome during assembly and disassembly, inconvenient for workers, and reduces the efficiency of riveting work, the basic concept of this utility model is as follows: The pulley press riveting bracket positioning assembly includes a riveting device and a base installed on the riveting device. The riveting device and the base are equipped with a disassembly mechanism and a positioning mechanism. The disassembly and assembly mechanism includes a positioning rod on the top surface of the riveting equipment, and a positioning hole is provided at the bottom end of the base. The positioning rod and the positioning hole are matched to limit and fix the position of the base. The positioning mechanism includes a positioning seat mounted on a base. A limiting plate is connected to the outer wall of the positioning seat, and a limiting post is connected to the top surface of the base. The limiting plate and the limiting post are configured to engage and limit the position of the positioning seat.

[0006] In a preferred embodiment of this utility model, the disassembly and assembly mechanism includes a mounting sleeve connected to the outer wall of the riveting equipment. A motor is mounted on the inner wall of the mounting sleeve. A bidirectional lead screw is connected to the output end of the motor. A threaded block is threaded to the outer wall of the bidirectional lead screw. A push rod is connected to the outer wall of the threaded block. A connecting ring is connected to the bottom outer wall of the positioning rod. A spring is connected to the top surface of the connecting ring. The end of the spring away from the connecting ring is connected to the top of the inner wall of the riveting equipment. A force-bearing inclined surface is formed on the bottom outer wall of the positioning rod.

[0007] In a preferred embodiment of the present invention, the positioning mechanism includes a cylinder mounted on the top surface of the base, and positioning seats are connected to the outer walls on both sides of the limiting plate, with a placement groove opened on the top surface of the positioning seat.

[0008] In a preferred embodiment of the present invention, the top surface of the riveting device is provided with a guide groove, and a guide roller is movably arranged on the inner wall of the guide groove. The top surface of the guide roller is connected to the bottom end of the base.

[0009] In a preferred embodiment of this utility model, there are four positioning rods and four positioning holes. The positioning rods and positioning holes are arranged in pairs on the riveting equipment and the base, and the two fit together properly.

[0010] In a preferred embodiment of this utility model, the top surface of the limiting plate is provided with an insertion hole, and the outer wall of the limiting post is inserted into the inner wall of the insertion hole.

[0011] In a preferred embodiment of this utility model, there are four limiting posts, which are symmetrically distributed on the top of the base in pairs and fit snugly against the inner wall of the insertion hole on the limiting plate.

[0012] Compared with the prior art, the present invention has the following advantages: This invention uses guide rollers to push the guide rod into the guide groove, so that the positioning hole at the bottom of the base corresponds to the positioning rod. Then, the motor drives the bidirectional lead screw to rotate, which causes the push rod to move closer to each other. This releases and squeezes the positioning rod, causing it to move upward and insert into the inner wall of the positioning hole, thus limiting and fixing the position of the base. Compared with bolt fixing, this invention allows for more convenient assembly and disassembly, thereby improving riveting efficiency.

[0013] This invention aligns and engages the limiting plates on both sides of the positioning seat with the outer wall of the limiting column, thus initially positioning the positioning seat. After placing the pulley and bracket in the placement groove, the cylinders on both sides can be activated. The pulley can be clamped and limited by the contact compression at its output end, thereby ensuring the riveting stability of the pulley and bracket during the riveting pressing process, thus improving the riveting quality and effect.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0018] like Figures 1 to 5As shown, the riveting and positioning assembly of the pulley riveting bracket includes a riveting device 1 and a base 2 installed on the riveting device 1. The riveting device 1 and the base 2 are equipped with a disassembly and assembly mechanism 31 and a positioning mechanism 32. The disassembly and assembly mechanism 31 includes a positioning rod 316 on the top surface of the riveting device 1 and a positioning hole 3110 at the bottom end of the base 2. The positioning rod 316 and the positioning hole 3110 are matched to limit and fix the position of the base 2. The positioning mechanism 32 includes a positioning seat 324 on the base 2. A limiting plate 323 is connected to the outer wall of the positioning seat 324 and a limiting post 322 is connected to the top surface of the base 2. The limiting plate 323 and the limiting post 322 are matched to lock and limit the position of the positioning seat 324.

[0019] Furthermore, the disassembly and assembly mechanism 31 includes an installation sleeve 311 connected to the outer wall of the riveting equipment 1. A motor 312 is installed on the inner wall of the installation sleeve 311. A bidirectional lead screw 313 is connected to the output end of the motor 312. A threaded block 314 is threaded to the outer wall of the bidirectional lead screw 313. A push rod 315 is connected to the outer wall of the threaded block 314. A connecting ring 317 is connected to the outer wall of the bottom end of the positioning rod 316. A spring 318 is connected to the top surface of the connecting ring 317. The end of the spring 318 away from the connecting ring 317 is connected to the top of the inner wall of the riveting equipment 1. A force-bearing inclined surface 319 is opened on the outer wall of the bottom end of the positioning rod 316.

[0020] Furthermore, the top surface of the riveting device 1 is provided with a guide groove 3111, and a guide roller 3112 is movably arranged on the inner wall of the guide groove 3111. The top surface of the guide roller 3112 is connected to the bottom end of the base 2.

[0021] Furthermore, there are four positioning rods 316 and four positioning holes 3110. The positioning rods 316 and the positioning holes 3110 are arranged in pairs on the riveting device 1 and the base 2, and the two fit together properly. This can improve the tightness of the outer wall of the positioning rod 316 inserted into the inner wall of the positioning hole 3110, thereby improving the positioning stability of the base 2.

[0022] The positioning mechanism 32 includes a cylinder 321 installed on the top surface of the base 2, and positioning seats 324 connected to the outer walls on both sides of the limiting plate 323. The top surface of the positioning seat 324 is provided with a placement groove 325.

[0023] Furthermore, an insertion hole is provided on the top surface of the limiting plate 323, and the outer wall of the limiting post 322 is inserted into the inner wall of the insertion hole. The insertion hole can be used to fit and engage with the limiting post 322, thereby limiting and fixing the positioning seat 324.

[0024] Furthermore, there are four limiting posts 322, which are symmetrically distributed in pairs at the top of the base 2 and fit snugly against the inner wall of the insertion hole on the limiting plate 323. This improves the tightness of the fit between the limiting posts 322 and the inner wall of the insertion hole, thereby improving the limiting stability of the positioning seat 324.

[0025] The implementation principle of the pulley riveting bracket positioning assembly in this embodiment is as follows: After placing the pulley and bracket on the placement groove 325, the guide roller 3112 at the bottom of the base 2 can be pushed into the guide groove 3111, so that the base 2 is initially positioned on the external riveting equipment 1. At this time, the positioning hole 3110 opened at the bottom of the base 2 will correspond to the positioning rod 316 set on the top surface of the riveting equipment 1. Then, the motor 312 can be started, and its output end will drive the bidirectional lead screw 313 to rotate. As the bidirectional lead screw 313 rotates, it will drive the threaded block 314 threaded on its outer wall to move closer to each other. As the threaded block 314 moves, it will drive the push rod 315 to move. At this time, the push rod 315 will contact and press the force-bearing inclined surface 319 opened at the bottom of the positioning rod 316 during the movement. The positioning rod 316 is pressed. This generates an upward force, causing the positioning rod 316 to move upward. The top outer wall of the positioning rod 316 will then be inserted into the inner wall of the positioning hole 3110 at the bottom of the corresponding base 2. Simultaneously, as the positioning rod 316 moves upward, it will drive the connecting ring 317 to move. At this time, the connecting ring 317 can compress the spring 318. Thus, the positioning rod 316 and the positioning hole 3110 can be used to horizontally lock and limit the position of the base 2, thereby ensuring the stability of the base 2 during the riveting process. Compared with using bolts for fastening, this method can limit the position more quickly, thereby improving the riveting efficiency. During disassembly, simply reverse the motor 312 to drive the push rod 315 away from the positioning rod 316, and then the spring 318 will rebound to drive the positioning rod 316 downward, so that the outer wall of the positioning rod 316 is separated from the inner wall of the positioning hole 3110. Then, pull the base 2 outward to make the guide roller 3112 separate from the inner wall of the guide groove 3111 to complete the disassembly.

[0026] Before placing the pulley and bracket, first place the positioning seat 324 on the base 2, so that the limiting plates 323 on both sides of the positioning seat 324 are aligned and inserted into the outer wall of the limiting post 322. The positioning seat 324 can be positioned by limiting the limiting post 322. Then, start the cylinder 321. After that, place the pulley and bracket in the placement groove 325. Then start the cylinders 321 on both sides. Their output ends will contact and squeeze the pulley to position it, thereby ensuring the stability of the pulley during the riveting pressing process, thus ensuring the quality and effect of riveting.
