Description

An inner plate for automotive reinforcing panels and its clamping and punching device Technical Field

[0001] This application relates to the field of automotive reinforcement plate processing, and in particular to an inner plate of an automotive reinforcement plate and a clamping and punching device thereof. Background Technology

[0002] Automotive reinforcement panels are internal structural components in the automotive body structure used to enhance the rigidity, stability, and safety of the vehicle body. These components are made of metal, plastic, composite materials, or other materials and are installed on the internal frame or panels of the vehicle body.

[0003] Before being put into use, the inner panel of the automotive reinforcement plate needs to be perforated at designated locations using a punching device to meet subsequent installation requirements.

[0004] However, since the inner panels of automotive reinforcing plates are mostly irregularly shaped, the punching devices in traditional technology have difficulty in performing multi-point positioning according to the shape of the inner panels. This makes it easy for the punching position to deviate from the preset position due to insufficient positioning accuracy of the inner panels. Therefore, this technology needs to be improved. Summary of the Invention

[0005] To address the problem of difficulty in multi-point positioning based on the shape of the inner panel of an automotive reinforcing plate, which easily leads to deviations between the punching position and the preset position due to insufficient positioning accuracy of the inner panel, this application provides an inner panel of an automotive reinforcing plate and its clamping and punching device.

[0006] The technical solution provided in this application for an inner panel of an automotive reinforcing plate and its clamping and punching device is as follows: an inner panel of an automotive reinforcing plate includes a base, the middle of which is recessed to form a groove-shaped bottom, and positioning holes and mounting holes are respectively provided at both ends of the bottom of the base, and the edge of the base extends outward to form an edge portion.

[0007] By adopting the above technical solution, the overall structure can be optimized, and the substrate can be conveniently installed in a designated position using the mounting holes.

[0008] A clamping and punching device for an inner panel of an automotive reinforcing plate includes: a crossbeam, one end of which is fixedly connected to an extension beam, and the bottom end of the extension beam is fitted with an edge clamping component A for engaging with one end of an edge positioning substrate; an end positioning component, which is fitted at the other end of the crossbeam for engaging with the other end of the edge positioning substrate; an edge clamping component B, which is fitted at the middle of the crossbeam for engaging with the middle of the edge positioning substrate; and a punching component, which is fitted at the bottom end of the crossbeam for generating mounting holes in the substrate.

[0009] By adopting the above technical solution, the multi-point positioning of the substrate is formed by setting the edge clamping component A, the end positioning component and the edge clamping component B, so as to avoid uncontrollable movement of the substrate during the operation of the punching component and thus ensure the stability of the punching component during punching.

[0010] Optionally, the edge clamping assembly A includes: a support A, with an assembly hole A at its top, a fixed clamping plate A fixedly connected to one end of the support A, an assembly rod A fixedly connected to the bottom of the extension beam, and the support A being assembled onto the assembly rod A through the assembly hole A; and a push rod A, which is vertically slidably connected to the other end of the support A, with an adjusting seat A fixedly connected to the bottom of the push rod A, and a movable clamping plate A cooperating with the fixed clamping plate A fixedly connected to the bottom end of the adjusting seat A.

[0011] By adopting the above technical solution, the edge part of the substrate can be positioned between the fixed clamping plate A and the moving clamping plate A by means of the controllable adjustment of the push rod A.

[0012] Optionally, the edge clamping assembly B includes: a support base B, one end of which is fixedly connected to a fixed clamping plate B, the top of which has an assembly hole B, an assembly rod B fixedly connected to the middle of the bottom end of the crossbeam, a support rod fixedly connected to the bottom of the assembly rod B, and the support base B being assembled on the outside of the support rod through the assembly hole B; and a push rod B, which is vertically slidably connected to the middle of the support base B, and the bottom end of which is fixedly connected to a movable clamping plate B that cooperates with the fixed clamping plate B.

[0013] By adopting the above technical solution, the edge part of the base can be positioned between the fixed clamping plate B and the moving clamping plate B by means of the controllable adjustment of the push rod B.

[0014] Optionally, the end positioning assembly includes: a support C, the top of which has an assembly hole C, one end of which is fixedly connected to a fixed clamping plate C, and the bottom of the other end of the base is fixedly connected to an assembly rod C, and the support C is assembled to the outside of the assembly rod C through the assembly hole C; and a push rod C, which is vertically slidably connected to the middle of the support C, the bottom end of which is fixedly connected to an adjusting seat B, and one end of the adjusting seat B is fixedly connected to a movable clamping plate C that cooperates with the fixed clamping plate C.

[0015] By adopting the above technical solution, the end of the base can be limited between the fixed clamping plate C and the moving clamping plate C by means of the controllable adjustment of the push rod C.

[0016] Optionally, the top ends of push rods A, B, and C are all equipped with linkage components, and the top of the crossbeam is provided with a transmission component. The linkage components are used to cooperate with the transmission component to drive push rods A, B, and C to move synchronously.

[0017] By adopting the above technical solution, the push rods A, B and C are easily assembled and disassembled with the linkage components using the linkage components. While ensuring overall stability, it is also possible to avoid the transmission components affecting the subsequent adjustment of the edge clamping components A, end positioning components and edge clamping components B.

[0018] Optionally, the linkage assembly includes: a hollow shaft, one end of which is fixedly connected to an assembly cylinder, and the assembly cylinder is also rotatably connected to the outside of a fixed clamping plate A, a push rod B, or a push rod C; a base plate is fixedly connected to the end of the hollow shaft away from the assembly cylinder; a locking plate is fixedly connected to the top of the base plate; a displacement plate is vertically slidably connected to the bottom of the base plate; a guide frame is fixedly connected to the bottom of the displacement plate; a guide slot is provided in the middle of the guide frame; a displacement rod is slidably connected inside the hollow shaft; a stabilizing block is fixedly connected to the end of the displacement rod near the assembly cylinder; and a linkage rod. The linkage rod is embedded in the end of the displacement rod near the base plate. One end of the linkage rod has a threaded section, and a stop block is threadedly connected to the outer side of the threaded section. The rotating shaft is rotatably connected to the bottom of the base plate. One end of the rotating shaft is fixedly connected to an eccentric plate A. The end of the eccentric plate A away from the rotating shaft is fixedly connected to a guide rod A, and the guide rod A is also movably connected inside the guide slot. The eccentric plate B is fixedly connected to the end of the eccentric plate A away from the guide rod A. The middle of the eccentric plate B has a linkage slot, and the other end of the linkage rod is also movably connected inside the linkage slot.

[0019] By adopting the above technical solution, rotating the stop block causes it to adjust along the threaded section. When the stop block moves away from the hollow shaft, the displacement rod can be unlocked. Then, the displacement rod is pulled away from the assembly cylinder, causing it to disengage from push rod A, push rod B, or push rod C, reducing the resistance during the rotation of the assembly cylinder. Subsequently, the hollow shaft is pulled, causing it to rotate under the support of the assembly cylinder, and pulling the corresponding assembly plate, causing it to rotate under the support of the support shaft. When the assembly plate reaches below the locking plate, and the stabilizing hole and the locking hole are aligned... When the displacement rod is pushed towards the assembly cylinder, it will make the displacement rod fit tightly against push rod A, push rod B, or push rod C. With the connection between the displacement rod and the linkage rod, the linkage rod will move synchronously with the displacement rod. With the connection between the linkage rod and the guide slot, when the linkage rod is adjusted, it can pull the eccentric plate B, causing the eccentric plate A to rotate under the support of the rotating shaft. This changes the position of the guide rod A inside the guide slot, so as to lift the displacement plate upward, causing the insertion rod to pass through the stabilizing hole and the locking hole, until the assembly plate is positioned between the displacement plate and the locking plate.

[0020] Optionally, the transmission assembly includes: a transmission frame, which is fixedly connected to the top of the crossbeam, with an adjusting frame vertically slidably connected to the top of the transmission frame, three support shafts fixedly connected to the adjusting frame, an assembly plate rotatably connected to the outer side of each support shaft, and an assembly seat fixedly connected to the bottom of the adjusting frame, the assembly seat having a waist hole; and a transmission motor, which is fixedly connected to one side of the transmission frame, with a central shaft fixedly connected to the output end of the transmission motor, an eccentric plate C fixedly connected to one end of the central shaft, and a guide rod B fixedly connected to the end of the eccentric plate C away from the central shaft, the guide rod B also being movably connected inside the waist hole.

[0021] By adopting the above technical solution, the substrate is placed at the top of the moving clamps A, B, and C. At the same time, the drive motor is started to drive the eccentric plate C to rotate through the central shaft. With the connection between the eccentric plate C and the guide rod B, when the guide rod B rotates with the eccentric plate C, the adaptive movement of the guide rod B inside the waist hole can cause the adjusting frame to move vertically. Since the assembly plate is located between the adjusting frame and the hollow shaft, the push rods A, B, and C can move synchronously under the action of the assembly plate and the hollow shaft, thereby changing the vertical height of the moving clamps A, B, and C until the substrate contacts the fixed clamps A, B, and C, thus forming the positioning of the substrate before punching.

[0022] Optionally, the punching assembly includes: a positioning seat, the top of which has an assembly hole D, and the bottom of the crossbeam is fixedly connected to a positioning rod A, and the positioning seat is assembled on the outside of the positioning rod A through the assembly hole D; a cylinder A, which is fixedly connected to one end of the positioning seat, the output end of the cylinder A is fixedly connected to a displacement frame A, one end of the displacement frame A is fixedly connected to a cylinder B, and the output end of the cylinder B is fixedly connected to a displacement frame B; and a cylinder C, which is fixedly connected to the top of the displacement frame B, the output end of the cylinder C is fixedly connected to a bearing box, and the bottom end of the bearing box is fixedly connected to a punch.

[0023] By adopting the above technical solution, cylinder A is used to push displacement frame A to make longitudinal adjustment, changing the longitudinal position of the punch. Then, cylinder B is started to push displacement frame B to make lateral adjustment, changing the lateral position of the punch. When the punch reaches the designated punching position, cylinder C is started to push the carrier box downward to adjust. When the punch contacts the base, the mounting hole can be opened on the base.

[0024] Optionally, it also includes a stability support, the top of which has an assembly hole E, the bottom of which is fixedly connected to a positioning rod B, and the stability support is connected to the positioning rod B through the assembly hole E. The top of which is fixedly connected to a cylinder D, and the output end of the cylinder D is fixedly connected to a positioning plug.

[0025] By adopting the above technical solution, before punching the base, the cylinder D is activated to push the positioning plug downward and adjust it so that the end positioning component is inserted into the positioning hole, thereby locking the base again and preventing uncontrollable displacement of the base during punching.

[0026] In summary, this application includes at least one of the following beneficial technical effects: By configuring the edge clamping component A, the end positioning component, and the edge clamping component B, multi-point positioning can be achieved before punching the substrate, ensuring substrate clamping stability while preventing damage to the inner plate of the substrate; through the combined assembly of the linkage component and the transmission component, the required power for clamping the edge clamping component A, the end positioning component, and the edge clamping component B can be provided, while preventing the transmission component from affecting the subsequent position adjustment of the edge clamping component A, the end positioning component, and the edge clamping component B, greatly ensuring overall applicability; through the structural cooperation of the punching components, multi-point punching operations on the substrate can be achieved with the controllable adjustment of the punch, greatly ensuring overall punching efficiency.

When installing bearing seats B18, C25, locating seats 65, and stabilizing seats 76, first pass the bolts through the clearance holes of the connectors, then tighten the bolts. This causes bearing seats A11, B18, C25, locating seats 65, and stabilizing seats 76 to deform under the action of the deformation grooves. This, in turn, clamps the round holes to the assembly rods A14, 22, C28, A67, and B78, thus achieving the desired effect for bearing seats A11, B18, C25, locating seats 65, and stabilizing seats 76. Positioning; Referring to Figure 13, in this embodiment, the crossbeam 5 has multiple mounting holes. The tops of the mounting rod A14, bearing rod 22, mounting rod C28, positioning rod A67, and positioning rod B78 are all equipped with mounting plates, and the mounting plates are connected to the mounting holes by bolts; More specifically, through the cooperation of the bolts and mounting holes, the mounting plates can be stably locked on the crossbeam 5, and when the size of the base 1 changes later, the bolts on the mounting plates can be removed, the mounting plates can be adjusted to the required position, and then locked with bolts.

[0047] The implementation principle of the inner plate of an automotive reinforcing plate and its clamping and punching device according to an embodiment of this application is as follows: First, the assembly hole A12 is fitted onto the assembly rod A14, and the bearing seat A11 is rotated under the support of the assembly rod A14, so that the fixed clamping plate A13 and the movable clamping plate A17 reach the edge of the base 1. Then, the position of the bearing seat A11 is locked. Next, the bearing seat B18 is fitted onto the bearing rod 22 until the fixed clamping plate B19 and the movable clamping plate B24 reach the edge of the base 1, and then the position of the bearing seat B18 is locked. Finally, the bearing seat C25 is fitted onto the assembly rod C28, and the bearing seat C25 is rotated, so that the fixed clamping plate C27 reaches above the base 1 and the movable clamping plate C31 reaches below the base 1. The stop block 48 is rotated, so that the stop block 48 moves along the screw thread. After adjusting section 47, once the stop block 48 is away from the hollow shaft 35, the displacement rod 44 can be unlocked. Then, pull the displacement rod 44 away from the assembly cylinder 36, causing it to disengage from push rod A15, push rod B23, or push rod C29, reducing resistance during the rotation of the assembly cylinder 36. Next, pull the hollow shaft 35, causing it to rotate under the support of the assembly cylinder 36, and pull the corresponding assembly plate 57, causing it to rotate under the support of the support shaft 56. When the assembly plate 57 reaches below the locking plate 38, and the stabilizing hole 58 aligns with the locking hole 39, push the displacement rod 44 towards the assembly cylinder 36, causing it to engage with the push rod A15 or... Push rod B23 or push rod C29 fits tightly together; in conjunction with the connection between displacement rod 44 and linkage rod 46, linkage rod 46 will move synchronously with displacement rod 44. With linkage rod 46 connected to guide slot 43, during the adjustment of linkage rod 46, it can pull eccentric plate B52, causing eccentric plate A50 to rotate under the support of rotating shaft 49, thereby changing the position of guide rod A51 inside guide slot 43, so as to lift displacement plate 40 upward, causing insertion rod 41 to pass through stabilizing hole 58 and locking hole 39, until assembly plate 57 is positioned between displacement plate 40 and locking plate 38; then base 1 is placed on top of moving clamping plate A17, moving clamping plate B24 and moving clamping plate C31, and drive motor 61 is started at the same time. The eccentric plate C63 is rotated by the central shaft 62, and the eccentric plate C63 is connected to the guide rod B64. When the guide rod B64 rotates with the eccentric plate C63, the adaptive movement of the guide rod B64 inside the waist hole 60 can cause the adjusting frame 55 to move vertically. Since the assembly plate 57 is located between the adjusting frame 55 and the hollow shaft 35, the push rods A15, B23 and C29 can move synchronously under the action of the assembly plate 57 and the hollow shaft 35, thereby changing the vertical height of the moving clamps A17, B24 and C31 until the base 1 contacts the fixed clamps A13, B19 and C27, thus forming the positioning of the base 1 before punching.During punching, cylinder A68 is activated to push displacement frame A69 for longitudinal adjustment, thereby changing the longitudinal position of punch 74. Then, cylinder B70 is activated to push displacement frame B71 for lateral adjustment, thereby changing the lateral position of punch 74. When punch 74 reaches the designated punching position, cylinder C72 is activated to push carrier box 73 downward. When punch 74 contacts base 1, mounting hole 3 can be opened on base 1. Furthermore, when the dimensions of base 1 change subsequently, assembly plate 57 is first removed from between locking plate 38 and displacement plate 40. Then, by removing bolts, the positions of fixed clamping plate A13, fixed clamping plate B19, fixed clamping plate C27, movable clamping plate A17, movable clamping plate B24, and movable clamping plate C31 are adjusted. After adjustment, assembly plate 57 is then re-locked between the corresponding locking plate 38 and displacement plate 40.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
