Description

Technical Field

[0001] The utility model relates to the technical field of pressure riveting, in particular to a pressure riveting product switching mechanism. Background Art

[0002] Compression riveting is a joining technique that involves placing a rivet between the materials to be joined. Using a specialized tool, pressure is applied, causing the rivet to deform and securely attach to the materials. This method is commonly used to join metal components, offering high strength and durability, and is widely used in the automotive, aviation, and construction industries.

[0003] The riveting process is currently widely used in the production of automotive parts for bodywork structures. Due to the wide variety of products, the corresponding bracket baseplates for the riveting dies vary in shape, necessitating frequent replacement of the baseplates. This is a time-consuming operation and hinders production efficiency. Furthermore, products have high repair requirements and high repair rates. Repeated assembly and disassembly of the baseplates can lead to uneven pressure during installation, resulting in deformation that affects precision and, in turn, product quality. Utility Model Content

[0004] The purpose of the present utility model is to provide a riveting product switching mechanism that can quickly replace a bracket substrate and avoid repeated disassembly and assembly, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a riveting product switching mechanism, comprising a housing, a through slot formed on the top of the housing, a rotating shaft provided inside the housing, and both ends of the rotating shaft extending to the outside of the housing, four bracket base plates being installed in a coaxial array on the outer surface of the rotating shaft, and the bracket base plates being adapted to the through slot. A first bearing is sleeved on the outer surface of the rotating shaft near both ends, two hydraulic cylinders are installed inside the housing, and the ends of the telescopic ends of the hydraulic cylinders are connected to the first bearing. A hexagonal slot is formed on both ends of the rotating shaft, and four positioning holes are formed on the outer surface of both ends of the rotating shaft in a coaxial array around the hexagonal slot, and a fixing mechanism is provided on the outer surface of the housing that plugs into and fits with the positioning holes.

[0006] It can be seen that by integrating the four bracket substrates together, when in use, it is only necessary to rotate the required bracket substrate to the corresponding through slot and fix it through the fixing mechanism, and then lift the bracket substrate into the through slot through the hydraulic cylinder, so as to complete the rapid replacement of the bracket substrate and improve the production efficiency of the product; and avoid the problem of repeated disassembly and assembly, and avoid the pressure deformation caused by uneven pressure application during installation affecting the accuracy, thereby causing defective products, and the remaining bracket substrates are all inside the box when not in use, which can play a protective role and avoid damage and deformation caused by collision.

[0007] Furthermore, the fixing mechanism includes a U-shaped plate arranged on the outer surface of the box body, two insertion rods are arranged through the interior of the U-shaped plate, and a handle is installed on the end of the two insertion rods facing away from the rotating shaft. The outer surface of the insertion rod is provided with a shaft shoulder, and the outer surface of the insertion rod is provided with a spring, and the two ends of the spring are respectively in contact with the U-shaped plate and the shaft shoulder.

[0008] When rotating the shaft, first pull the handle outward to drive the two rods to be pulled out of the positioning holes at the same time. At this time, the shaft is released, so the shaft can be rotated by using an L-shaped hexagonal wrench. When the bracket base plate to be used is adjusted to correspond to the through slot, the rods can be reinserted into the positioning holes to fix the shaft.

[0009] Furthermore, two slide grooves are provided inside the box body, and the slide grooves are connected to the through grooves, a baffle is provided inside the slide grooves, a connecting groove is provided on the upper surface of the box body, a push block is provided inside the connecting grooves, and the push block is installed on the upper surface of the baffle.

[0010] When the bracket base plate is not in use, the hydraulic cylinder can drive all the bracket base plates to retract into the box body, and then push the push block to drive the baffle to slide to cover the through slot, thereby achieving the purpose of dust prevention and preventing dust from falling on the bracket base plate and affecting the use effect.

[0011] Furthermore, both ends of the rotating shaft are sleeved with second bearings, the outer surfaces of both sides of the second bearings are connected with mounting plates, and the mounting plates are slidably connected to the outer surface of the box, and the U-shaped plates are installed on the two mounting plates.

[0012] By setting the second bearing and the mounting plate, the two ends of the rotating shaft can be limited, thereby improving its structural stability and providing an installation position for the fixing mechanism so that the fixing mechanism can rise and fall with the rising and falling of the rotating shaft.

[0013] Furthermore, grooves are provided on both sides of the bracket substrate in the width direction, and the baffles are adapted to the grooves.

[0014] By setting the groove, when the bracket base plate rises into the through groove, the baffles on both sides can be slid and inserted into the groove, thereby supporting the bracket base plate and improving its structural stability.

[0015] Furthermore, a ball is provided on one end of the insertion rod facing the rotating shaft.

[0016] When the insertion rod is pulled out of the positioning hole and the shaft is rotated, the grip can be loosened, and the insertion rod is pushed against the outer surface of the end of the shaft under the elastic force of the spring. When the shaft rotates to correspond to the insertion rod, the compressed spring releases the elastic force, allowing the insertion rod to be automatically inserted into the positioning hole for fixation, thereby improving operational efficiency and the accuracy of the docking between the insertion rod and the positioning hole. Therefore, by setting the ball, the friction resistance between the end of the insertion rod and the shaft can be reduced, wear can be reduced, and smoothness can be improved.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By integrating the four bracket baseplates together, when in use, you only need to rotate the required bracket baseplate to the corresponding through-slot and fix it through the fixing mechanism. Then, the bracket baseplate is lifted into the through-slot by the hydraulic cylinder, thereby completing the rapid replacement of the bracket baseplate, improving product production efficiency, and avoiding the precision error problem caused by repeated disassembly and assembly;

[0019] 2. When the bracket base plate is not in use, the hydraulic cylinder can be used to drive all the bracket base plates to retract into the box body, and then the push block is pushed to drive the baffle to slide to cover the through slot, thereby achieving the purpose of dust prevention and preventing dust from falling on the bracket base plate and affecting the use effect.

[0030] See also Figure 1-6 , an embodiment provided by the utility model:

[0031] A riveting product switching mechanism includes a box body 100, a through slot 101 is provided on the top of the box body 100, a rotating shaft 102 is provided inside the box body 100, and both ends of the rotating shaft 102 extend to the outside of the box body 100, and four bracket substrates 103 are installed in a coaxial array on the outer surface of the rotating shaft 102, and the bracket substrate 103 is adapted to the through slot 101. By integrating the four bracket substrates 103 together, when in use, the required bracket substrate 103 only needs to be rotated to the corresponding through slot 101 to complete the rapid replacement of the bracket substrate 103. The outer surfaces of the rotating shaft 102 near both ends are sleeved with first bearings 104. Two hydraulic cylinders 105 are installed inside the housing 100. The ends of the hydraulic cylinders 105 are connected to the first bearings 104. The hydraulic cylinders 105 drive the rotating shaft 102 downward, freeing up space for rotating the rotating shaft 102. The hydraulic cylinders 105 drive the rotating shaft 102 upward, allowing the required bracket base plate 103 to be extended outward from the through slot 101 for use. Hexagonal slots 107 are provided at both ends of the rotating shaft 102. Four positioning holes 106 are provided on the outer surfaces of both ends of the rotating shaft 102 in a coaxial array around the hexagonal slots 107. The outer surface of the housing 100 is provided with a fixing mechanism 200 that plugs into the positioning holes 106. By inserting an L-shaped hexagonal wrench into the hexagonal slots 107, the rotating shaft 102 can be easily driven to rotate. The fixing mechanism 200 plugs into the positioning holes 106 to fix the rotating shaft 102.

[0032] See also Figure 1 、 Figure 3 and Figure 4The fixing mechanism 200 includes a U-shaped plate 201 arranged on the outer surface of the box body 100, and two insertion rods 202 are provided inside the U-shaped plate 201. The two insertion rods 202 are jointly installed with a handle 203 at one end away from the rotating shaft 102, and the outer surface of the insertion rod 202 is provided with a shoulder 204. The outer surface of the insertion rod 202 is sleeved with a spring 205, and the two ends of the spring 205 are respectively in contact with the U-shaped plate 201 and the shoulder 204. When the rotating shaft 102 is rotated, the handle 203 is first pulled outward, so that it drives the two insertion rods 202 to be pulled out of the positioning holes 106 at the same time. At this time, the rotating shaft 102 is released, so the rotating shaft 102 can be driven to rotate by an L-shaped hexagonal wrench. When the bracket base plate 103 to be used is adjusted to correspond to the through slot 101, the insertion rod 202 can be reinserted into the positioning hole 106 to fix the rotating shaft 102. Both ends of the rotating shaft 102 are sleeved with second bearings 400, and the outer surfaces of both sides of the second bearings 400 are connected to mounting plates 401, and the mounting plates 401 are slidably connected to the outer surface of the box body 100, and the U-shaped plate 201 is installed on the two mounting plates 401. Through the setting of the second bearings 400 and the mounting plates 401, the two ends of the rotating shaft 102 can be limited to improve its structural stability, and provide an installation position for the fixing mechanism 200, so that the fixing mechanism 200 can follow the lifting and lowering of the rotating shaft 102. A ball 600 is provided at the end of the insertion rod 202 facing the rotating shaft 102. When the insertion rod 202 is pulled out from the positioning hole 106 and the rotating shaft 102 is rotated, the grip 203 can be loosened, and the insertion rod 202 is pushed against the outer surface of the end of the rotating shaft 102 under the elastic force of the spring 205. When the rotating shaft 102 rotates to correspond to the insertion rod 202, the compressed spring 205 releases the elastic force, allowing the insertion rod 202 to be automatically inserted into the positioning hole 106 for fixation, thereby improving the operating efficiency and the accuracy of the docking of the insertion rod 202 with the positioning hole 106. Therefore, by providing the ball 600, the friction resistance between the end of the insertion rod 202 and the rotating shaft 102 can be reduced, wear can be reduced, and smoothness can be improved.

[0033] See also Figure 2 、 Figure 5 and Figure 6Two slide grooves 300 are provided inside the box body 100, and the slide grooves 300 are connected to the through groove 101. A baffle 301 is provided inside the slide groove 300, and a connecting groove 302 is provided on the upper surface of the box body 100. A push block 303 is provided inside the connecting groove 302, and the push block 303 is installed on the upper surface of the baffle 301. When the bracket substrate 103 is not in use, the hydraulic cylinder 105 can be used to drive all the bracket substrates 103 to retract into the box body 100, and then the push block 303 is pushed to drive the baffle 301 to slide to cover the through groove 101, thereby achieving the purpose of dust prevention and preventing dust from falling on the bracket substrate 103 and affecting the use effect. Grooves 500 are provided on both sides of the width direction of the bracket substrate 103, and the baffles 301 are adapted to the grooves 500. Through the setting of the grooves 500, when the bracket substrate 103 rises into the through groove 101, the baffles 301 on both sides can be slid and inserted into the grooves 500, thereby supporting the bracket substrate 103 and improving its structural stability.

[0034] The specific workflow and working principle of this device are as follows.

[0035] When in use, first pull the handle 203 outwards to drive the two insertion rods 202 to be pulled out from the positioning holes 106 at the same time. At this time, the shaft 102 is released, and the L-shaped hexagonal wrench can be inserted into the hexagonal slot 107 to drive the shaft 102 to rotate. When the bracket base plate 103 to be used is adjusted to correspond to the through slot 101, the insertion rod 202 is reinserted into the positioning hole 106 to fix the shaft 102. Then the hydraulic cylinder 105 is started, which drives the shaft 102 to rise and drives the bracket base plate 103 to be used to extend outwards from the through slot 101 for use. Finally, the baffles 301 on both sides are slid and inserted into the grooves 500 on both sides of the bracket base plate 103, so that the bracket base plate 103 can be fixed. 03 plays a supporting role and improves its structural stability. By integrating the four bracket substrates 103 together, when in use, it is only necessary to rotate the required bracket substrate 103 to the corresponding through slot 101 and fix it through the fixing mechanism 200, and then lift the bracket substrate 103 into the through slot 101 through the hydraulic cylinder 105, thereby completing the rapid replacement of the bracket substrate 103 and improving the production efficiency of the product; and avoiding the problem of repeated disassembly and assembly, and avoiding the pressure deformation caused by uneven pressure application during installation to affect the accuracy, thereby causing defective products, and the remaining bracket substrates 103 are all inside the box body 100 when not in use, which can play a protective role and avoid damage and deformation caused by collision.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
