Description
Technical Field
[0001] This application relates to the field of riveting machines, and more particularly to a riveting fixture for commercial vehicle linings. Background Technology
[0002] Riveting is a common processing technique used in the production of automotive linings, often used to install and fix the ends of curved springs on the linings.
[0003] Existing riveting methods involve pressing rivets together using a press. The user inserts the rivet into the workpiece, positioning it vertically on the worktable. This causes the hydraulic cylinder above the worktable to extend, allowing the piston rod of the hydraulic cylinder to fall and press the end of the rivet, deforming the upper end of the rivet and thus enabling the rivet to connect the workpiece.
[0004] The aforementioned technical solutions have the following drawbacks: the rivets need to be vertically installed below the press and coaxially installed with the piston rod of the press. Placing the workpiece in the press requires a long positioning process, which makes the riveting process time-consuming. Utility Model Content
[0005] To reduce the time spent adjusting the rivet position, this application provides a riveting fixture for commercial vehicle linings.
[0006] The commercial vehicle lining riveting fixture provided in this application adopts the following technical solution:
[0007] A riveting fixture for commercial vehicle linings includes a riveting machine, an upper riveting component, a lower riveting component, and a backing plate. The riveting machine includes a machine body, a worktable, and a drive unit. The machine body is set on the ground, the worktable is horizontally set on one side of the machine body, and the drive unit is set on the machine body and located above the worktable. The upper riveting component is mounted on the drive unit, which is used to drive the upper riveting component to reciprocate in the vertical direction. The backing plate is set on the worktable, and the lower riveting component is mounted on the backing plate. An upper positioning hole is opened on the bottom surface of the upper riveting component, and a lower positioning hole is opened on the top surface of the lower riveting component. The upper positioning hole and the lower positioning hole are coaxially arranged.
[0008] By adopting the above technical solution, a pad is set on the workbench, and a lower riveting component is set on the pad, so that the upper and lower riveting components are positioned correspondingly. By opening upper and lower positioning holes, the user can vertically place the rivet in the lower positioning hole, allowing the rivet to pass through the workpiece. At this time, the driving component drives the upper riveting component to fall, which can make the upper riveting component press on the rivet, causing the upper end of the rivet to deform in the upper positioning hole and the lower end of the rivet to deform in the lower positioning hole. This makes the shape of the riveted rivet correspond to the upper and lower positioning holes, improving the riveting quality. The process of moving the workpiece and rivet during riveting is faster, and the processing efficiency is higher.
[0009] Optionally, the upper riveting component includes a rivet head and an elastic element. The rivet head is a cylindrical structure, vertically arranged, with its upper end face connected to the driving component and an upper positioning hole opened at the center of its lower end face. The elastic element is fixed on the lower end face of the rivet head and is used to abut against the workpiece.
[0010] By adopting the above technical solution, and by setting an elastic element on the rivet head, when the upper riveting part falls, the elastic element first abuts against the workpiece or rivet. As the rivet head continues to fall, it can press on the rivet, causing the rivet to deform. At this time, the elastic element is deformed by force and accumulates elastic potential energy. When the rivet head moves up, the rivet head disengages from the lower riveting part, and the elastic element can rebound and apply stress to the workpiece. At this time, the rivet can be dislodged from the upper positioning hole, reducing the probability of the rivet getting stuck in the upper positioning hole after riveting.
[0011] Optionally, the elastic element is configured as a cylindrical structure, and the elastic element is coaxially connected to the rivet head.
[0012] By adopting the above technical solution, by setting the elastic element as a cylinder, the cylindrical elastic element can evenly abut against the outer circumference of the rivet. When the contracted elastic element rebounds, the elastic element applies uniform stress to the rivet or workpiece, thereby reducing the probability of deformation of the workpiece or the riveted rivet.
[0013] Optionally, the lower riveting member is detachably connected to the pad, and the upper riveting member is detachably connected to the drive member.
[0014] By adopting the above technical solution, and by making the upper riveting component detachably connected to the drive component and the lower riveting component detachably connected to the pad, the user can replace the upper and lower riveting components, thereby adjusting the depth and diameter of the upper and lower positioning holes, and thus enabling the riveting machine to process rivets of various sizes.
[0015] Optionally, the upper surface of the pad is provided with a blind hole, and the lower rivet is snapped into the blind hole.
[0016] By adopting the above technical solution, blind holes are opened on the pad, allowing the lower riveting component to be inserted into the blind holes, thereby enabling the lower riveting component to maintain a stable position on the pad, making it convenient for users to install lower riveting components of different shapes on the pad.
[0017] Optionally, the pad has multiple blind holes, and each blind hole is provided with a lower riveting component.
[0018] By adopting the above technical solution, multiple blind holes are opened on the pad, and each blind hole can be used to install a lower riveting component. Users can set multiple lower riveting components on the pad and set rivets on each lower riveting component, thereby allowing multiple rivets to be inserted into the workpiece for installation, thus improving work efficiency.
[0019] Optionally, the workbench is equipped with multiple pins, which are vertically fixed to the workbench. The pad has multiple mounting holes, and the position and size of the pins correspond one-to-one with the mounting holes.
[0020] By adopting the above technical solution, and by setting a pin on the worktable so that the pin can be inserted into the pad, the pad can be engaged with the worktable, which can reduce the chance of the pad slipping on the worktable, improve the positional accuracy of the lower riveted parts, and improve the quality of rivet processing.
[0021] Optionally, the mounting holes are provided in groups, with multiple mounting holes in each group, and multiple pins can be inserted into the mounting holes in the same group respectively.
[0022] By adopting the above technical solution, and by opening multiple sets of mounting holes on the pad, the user can install the workpiece and multiple rivets on the lower riveting parts, and then sequentially rivet the rivets in the multiple lower riveting parts. After riveting one rivet, the user lifts the pad and inserts the pin into other mounting holes, thereby adjusting the position of the pad on the worktable so that the other lower riveting parts can be coaxially set below the upper riveting parts. The riveting work has high efficiency and high positional accuracy.
[0023] In summary, the beneficial technical effects of this application are as follows:
[0024] 1. By setting a pad on the workbench and placing a lower riveting component on the pad, the upper and lower riveting components are positioned to correspond. By opening upper and lower positioning holes, the user can vertically place the rivet in the lower positioning hole, allowing the rivet to pass through the workpiece. At this time, the driving component drives the upper riveting component to fall, which can press the upper riveting component on the rivet, causing the upper end of the rivet to deform in the upper positioning hole and the lower end of the rivet to deform in the lower positioning hole. This makes the shape of the riveted rivet correspond to the upper and lower positioning holes, improving the riveting quality. The process of moving the workpiece and rivet during riveting is faster, and the processing efficiency is higher.
[0025] 2. By setting an elastic element on the rivet head, when the upper riveting part falls, the elastic element first abuts against the workpiece or rivet. As the rivet head continues to fall, it can press on the rivet, causing the rivet to deform. At this time, the elastic element is deformed by force and accumulates elastic potential energy. When the rivet head moves up, the rivet head disengages from the lower riveting part, and the elastic element can rebound and apply stress to the workpiece. At this time, the rivet can be dislodged from the upper positioning hole, reducing the probability of the rivet getting stuck in the upper positioning hole after riveting.
[0026] 3. By opening multiple sets of mounting holes on the pad, the user can install the workpiece and multiple rivets on the lower riveting parts, and then rivet the rivets in the multiple lower riveting parts in sequence. After riveting one rivet, the user lifts the pad and inserts the pin into other mounting holes, thereby adjusting the position of the pad on the worktable so that the other lower riveting parts can be coaxially set below the upper riveting parts. The riveting work has high efficiency and high positional accuracy. Attached Figure Description

[0033] The present application will be further described in detail below with reference to the accompanying drawings.
[0034] This application discloses a riveting fixture for commercial vehicle linings, referring to... Figure 1 , Figure 2 and Figure 3The riveting machine includes a riveting machine 1, an upper riveting component 2, a lower riveting component 3, and a backing plate 4. The riveting machine 1 includes a machine body 11, a worktable 12, and a drive unit 13. The machine body 11 is set on the ground, the worktable 12 is horizontally fixed on the machine body 11, and the drive unit 13 is set on the machine body 11 and vertically above the worktable 12. The upper riveting component 2 is connected to the drive unit 13, which can be a hydraulic cylinder. The drive unit 13 drives the upper riveting component 2 to reciprocate vertically. In other embodiments, the riveting machine 1 can be a spin riveting machine. The drive unit 13 includes a hydraulic cylinder and a motor. The motor and the hydraulic cylinder jointly drive the main shaft of the riveting machine 1 to fall and rotate, thereby enabling the upper riveting component 2 to rotate while reciprocating vertically. The pad 4 is set on the workbench 12, and the lower riveting piece 3 is installed on the pad 4. The lower riveting piece 3 is located below the drive piece 13. The user places the workpiece to be processed and the rivet on the pad 4, so that the rivet is stuck in the lower riveting piece 3. At this time, the upper riveting piece 2 is controlled to fall, so that the upper riveting piece 2 and the lower riveting piece 3 can squeeze the rivet together, so that the workpiece completes the riveting process.
[0035] Reference Figure 2 and Figure 3 The upper riveting member 2 is a cylindrical structure. One end of the upper riveting member 2 is detachably connected to the driving member 13, and the other end has an upper positioning hole 211 at its center. The upper positioning hole 211 is used to abut against the rivet. The lower riveting member 3 is a cylindrical structure. The lower riveting member 3 is fixed on the pad 4 and coaxially arranged with the upper riveting member 2. The lower end of the lower riveting member 3 is connected to the pad 4, and the upper end has a lower positioning hole 31 at its center. The lower positioning hole 31 is used to engage with the rivet head. The user places the rivet vertically on the lower riveting member 3. By lowering the upper riveting member 2, the upper riveting member 2 and the lower riveting member 3 together squeeze the rivet, thereby deforming the rivet and completing the riveting of the workpiece.
[0036] Reference Figure 2 The upper riveting component 2 includes a rivet head 21 and an elastic element 22. The rivet head 21 is cylindrical and connected to the driving component 13. The rivet head 21 is vertically positioned with an upper positioning hole 211 on its lower end face. The elastic element 22 is a cylindrical structure and is coaxially connected to the lower end face of the rivet head 21. The elastic element 22 is made of rubber. When the rivet and the metal plate are placed in the riveting machine 1 for processing, the elastic element 22 abuts against the surface of the metal plate and deforms, allowing the rivet head 21 to continue falling and pressing down on the rivet. When the rivet deforms and the riveting is completed, the rivet is easily stuck in the upper positioning hole 211. At this time, the upper riveting component 2 moves upward, which can easily cause the workpiece to move upward with the upper riveting component 2, making it difficult to remove. By setting the elastic element 22 on the rivet head 21, when the upper riveting component 2 moves upward, the elastic element 22 rebounds and applies an elastic force to the metal plate, allowing the metal plate to drive the rivet out of the upper positioning hole 211, making it convenient for the user to move the processed workpiece.
[0037] Reference Figure 4 and Figure 5 In other embodiments, the lower riveting member 3 is detachably connected to the pad plate 4. The pad plate 4 has a blind hole 42, and the lower riveting member 3 is disposed in the blind hole 42. The lower riveting member 3 is snapped into the blind hole 42, and the user can install lower riveting members 3 of different shapes on the pad plate 4, thereby facilitating the riveting machine 1 to process rivets of different sizes.
[0038] Reference Figure 4 and Figure 5 In other embodiments, the pad 4 has multiple blind holes 42, and each blind hole 42 contains a lower riveting member 3. The user can place the workpiece and multiple rivets in the riveting machine 1, so that the multiple lower riveting members 3 respectively hold one rivet, thereby enabling continuous processing of multiple rivets on the workpiece.
[0039] Reference Figure 5 The pad 4 is detachably connected to the workbench 12. By moving the pad 4, the user can move multiple lower riveting parts 3 on the pad 4 to the lower part 2 in sequence, thereby improving work efficiency and reducing the work of positioning and adjusting the rivet position.
[0040] Reference Figure 4 The workbench 12 is provided with multiple pins 121, which are vertically arranged and whose lower ends are fixed to the workbench 12. The pad 4 is provided with multiple mounting holes 41, the position and size of which correspond one-to-one with the pins 121. When the multiple pins 121 are inserted into the mounting holes 41 respectively, the pad 4 is horizontally placed on the workbench 12 and maintains a stable position, reducing the probability of the pad 4 sliding on the workbench 12 and improving the positioning accuracy of the rivets.
[0041] Reference Figure 5 The mounting holes 41 are arranged in groups, with multiple mounting holes in each group. The spacing between two adjacent groups of mounting holes 41 is the same as the spacing between two adjacent lower riveting parts 3. When a rivet is processed, the operator lifts the pad 4 so that the pin 121 is inserted into the mounting holes 41 of other groups, which allows the gaseous riveting part 3 to be located below the upper riveting part 2, thereby improving the efficiency of riveting multiple rivets.
[0042] The implementation principle of this application embodiment is as follows: by setting an upper riveting member 2 on the riveting machine 1 and a lower riveting member 3 on the pad plate 4, the rivet can be vertically set in the lower positioning hole 31, thereby improving the efficiency of the riveting work. By setting an elastic member 22 on the rivet head 21, when the upper riveting member 2 falls and rivets the rivet, the elastic member 22 can abut against the surface of the metal workpiece and deform. When the upper riveting member 2 rises, the elastic member 22 releases elastic potential energy, so that the metal workpiece is subjected to downward stress, thereby allowing the rivet deformed by riveting to come out from the upper positioning hole 211.
[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. 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.
