Description

Technical Field

[0001] The utility model specifically relates to a floating guide hot riveting device. Background Art

[0002] The Chinese utility model patent document with the publication number "CN218892239U" discloses a fabric reverse-wrapping device for a column trim panel, including a reverse-wrapping upper template, a hot riveting assembly, a reverse-wrapping lower template, a side hot pressing mechanism, and a guide assembly, wherein the hot riveting assembly includes a hot riveting support seat, a hot riveting head, a hot riveting cylinder, and a hot riveting block. The column trim panel is placed in the lower mold, and the parallel hot pressing cylinder drives the parallel hot pressing block to move parallel to the column trim panel, and the fabric is applied to the upper end surface of the parallel part; at the same time, the side hot pressing cylinder drives the side pressure support seat to move toward the column trim panel, and the side hot pressing block applies the fabric to the upper end surface of the vertical part; then, the bending hot pressing cylinder drives the bending hot pressing block to apply the fabric to the inner side wall of the vertical part. The reversed upper die descends, and the hot riveting cylinder drives the hot riveting support seat and the hot riveting head to move vertically toward the column trim. The hot riveting block of the hot riveting head vertically passes through the hot riveting groove on the parallel hot pressing block, the side hot pressing block or the bending hot pressing block, and presses vertically on the fabric, so that the fabric is further attached to the column trim.

[0003] The hot riveting assembly in the fabric reverse-wrapping device of the column trim has the following technical defects: when the hot riveting cylinder drives the hot riveting head and the hot riveting block to move vertically toward the column trim for hot riveting, the hot riveting head and the hot riveting block will not float up and down relative to the hot riveting support seat, and the hot riveting action is "rigid contact", which makes it extremely difficult to control the pressure exerted by the hot riveting block on the fabric, so the fabric is often overheated or the contact between the fabric and the column trim is not tight. At the same time, the hot riveting block encounters resistance or obstacles during the hot riveting process, and the hot riveting block cannot automatically adjust its position or stop moving, which directly causes damage to the hot riveting block.

[0004] Therefore, it is necessary to improve the existing hot riveting components in the turn-up device used in structures such as column trim panels, so as to overcome the technical problem caused by "the hot riveting head cannot float up and down". Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a floating guide hot riveting device in view of the deficiencies of the above-mentioned prior art. When the hot riveting is working, the hot riveted parts can float up and down to ensure that the contact between the hot riveted parts and the fabric is more uniform and tight, avoiding excessive heating of the fabric or loose contact with the column trim, while protecting the hot riveted parts.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a floating guide hot riveting device, comprising a hot riveting component and a mounting plate, wherein the mounting plate is linked with a moving component capable of driving the mounting plate to move, and characterized in that: the hot riveting component is slidably connected to the mounting plate, a floating rod is provided above the hot riveting component, the floating rod is slidably connected to the mounting plate, a spring is provided on the outer periphery of the floating rod, and the spring is distributed between the hot riveting component and the mounting plate.

[0007] With the above technical solution, during the hot riveting process, the hot riveted parts can float in the vertical direction through the sliding connection between the floating rod and the mounting plate. When the hot riveted parts encounter fabrics of different thicknesses or uneven surfaces of parts such as pillar trims, the cooperation of the floating rod and the spring can enable the hot riveted parts to automatically adjust their positions to ensure that the contact between the hot riveted parts and the fabrics is more uniform and tight, avoiding excessive heating of the fabrics or loose contact with the pillar trims. The elastic force of the spring can automatically adjust the pressure applied by the hot riveting head to the fabric. When the hot riveting head encounters resistance or obstacles, the spring can absorb part of the impact force to prevent damage to the hot riveting head.

[0008] The above-mentioned floating guide hot riveting device can be further configured as follows: the mounting plate is provided with a mounting hole corresponding to the floating rod, a piston sleeve is fixed at the mounting hole, the upper end of the floating rod is inserted into the piston sleeve and the floating rod can reciprocate along the axial direction of the piston sleeve, the piston sleeve is connected with a limiting nut, the lower end of the floating rod is connected with an anti-collision cap, one end of the spring is in contact with the mounting plate, and the other end is in contact with the anti-collision cap.

[0009] With the above technical solution, the piston sleeve and the floating rod form a buffer, which not only enhances the floating force, but also enhances the stability of the hot riveted parts during the floating process, and at the same time, the service life of the buffer is longer. The anti-collision cap is connected to the lower end of the floating rod, mainly playing the role of buffering and protection. When the floating rod moves upward to the extreme position, the anti-collision cap can contact the mounting plate or other components to play a buffering role, preventing the floating rod and the hot riveted parts from being damaged by impact due to sudden stop.

[0010] The above-mentioned floating guide heat riveting device can be further configured as follows: the heat riveting part is detachably fixedly connected with a linkage part, the linkage part is fixedly connected with a slider, the slider is slidably matched with a slide rail, and the slide rail is fixed on the mounting plate.

[0011] By adopting the above technical solution, when the hot riveted part floats, the slider, the slide rail and the linkage cooperate with each other to guide the hot riveted part in sliding, ensuring that the floating path of the hot riveted part is always unique, while realizing the sliding connection between the hot riveted part and the mounting part.

[0012] The above-mentioned floating guide hot riveting device can be further configured as follows: the floating rod is distributed at the upper end of the linkage member, the mounting plate is provided with a lower limit member corresponding to the lower end of the linkage member, and the lower limit member is connected to the mounting plate through a threaded hole.

[0013] With the above technical solution, the lower limiter is used to limit the downward movement direction of the hot riveted part to prevent the hot riveted part from moving downward excessively. The lower limiter can preferably be a standard part such as a screw or a bolt, which is convenient for procurement and has good interchangeability and is easy to repair and replace. The lower limiter is connected to the mounting plate through a threaded hole, and the position of the lower limiter can be changed according to actual conditions to adapt to different working conditions.

[0014] The above-mentioned floating guide hot riveting device can be further configured as follows: the linkage part includes a first connecting block and a second connecting block which are detachably connected to each other by screws, a receiving groove structure which is sleeved on the outer periphery of the hot riveting part is provided between the first connecting block and the second connecting block, and the second connecting block is fixedly connected to the slider.

[0015] By adopting the above technical solution, the linkage part is configured as a separate first connecting block and a second connecting block, which facilitates the assembly of the linkage part and the hot riveted part. At the same time, during assembly, the gap between the first connecting block and the second connecting block can be changed according to the specifications of the hot riveted part to adapt to hot riveted parts of different specifications and types.

[0016] The above-mentioned floating guide heat riveting device can be further configured as follows: the outer periphery of the heat riveted component is provided with two groups of washers symmetrically attached to the outer periphery of the heat riveted component, and the lower end of the washers is provided with a limit platform.

[0017] By adopting the above technical solution, the washer can replace the hot riveting part to contact the linkage part, thereby avoiding excessive wear between the hot riveting part and the linkage part. When installing the washer, the limit table plays a positioning role.

[0018] The above-mentioned floating guide heat riveting device can be further configured as follows: a protective sleeve is connected to the outer periphery of the mounting plate.

[0019] The above technical solution is adopted to protect components such as sliders, slide rails, springs, floating rods, and linkage parts.

[0020] The above-mentioned floating guide hot riveting device can be further configured as follows: the moving component includes a multi-axis manipulator.

[0021] By adopting the above technical solution, the multi-axis manipulator can drive the hot riveted parts to move in space compared with cylinders, motors, etc., with a wider range of movement, so that the floating guide hot riveting device can be better used in assembly line production.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 3 The floating guide heat riveting device shown comprises a heat riveting component 1 and a mounting plate 3. The mounting plate 3 is linked with a moving component capable of driving the mounting plate 3 to move. The heat riveting component 1 is slidably connected to the mounting plate 3.

[0029] The moving assembly includes a multi-axis manipulator 2. Compared with a cylinder, a motor, etc., the multi-axis manipulator 2 can drive the hot riveted part 1 to move in space, and has a wider range of movement, so that the floating guide hot riveting device can be better applied to assembly line production.

[0030] A floating rod 4 is provided above the hot riveted part 1, and a spring 5 is provided on the outer peripheral sleeve of the floating rod 4. The spring 5 is distributed between the hot riveted part 1 and the mounting plate 3. The mounting plate 3 is provided with a mounting hole 3a corresponding to the floating rod 4, and a piston sleeve 6 is fixed at the mounting hole 3a. The upper end of the floating rod 4 is inserted into the piston sleeve 6 and the floating rod 4 can reciprocate along the axial direction of the piston sleeve 6. The piston sleeve 6 is connected to a limited position nut 7, and the lower end of the floating rod 4 is connected to an anti-collision cap 8. One end of the spring 5 is in contact with the mounting plate 3, and the other end is in contact with the anti-collision cap 8. The piston sleeve 6 and the floating rod 4 constitute a buffer, which not only enhances the floating force, but also enhances the stability of the hot riveted part 1 during the floating process, and at the same time, the service life of the buffer is longer. The anti-collision cap 8 is connected to the lower end of the floating rod 4, and mainly plays a role of buffering and protection. When the floating rod 4 moves upward to the limit position, the anti-collision cap 8 can contact the mounting plate 3 or other components to play a buffering role, preventing the floating rod 4 and the hot riveted part 1 from being impacted and damaged due to sudden stop.

[0031] The hot riveting part 1 is detachably fixedly connected with a linkage part 9, the linkage part 9 is fixedly connected with a slider 10, the slider 10 is slidably matched with a slide rail 11, and the slide rail 11 is fixed on the mounting plate 3. When the hot riveting part 1 is floating, the slider 10, the slide rail 11, and the linkage part 9 cooperate with each other to slide and guide the hot riveting part 1, ensuring that the floating path of the hot riveting part 1 is always unique, and at the same time realizing the sliding connection between the hot riveting part 1 and the mounting part.

[0032] The floating rod 4 is distributed at the upper end of the linkage member 9, and the mounting plate 3 is provided with a lower limit member 12 corresponding to the lower end of the linkage member 9, and the lower limit member 12 is connected to the mounting plate 3 through a threaded hole. The lower limit member 12 is used to limit the downward movement direction of the hot riveted part 1 to prevent the hot riveted part 1 from moving downward excessively. The lower limit member 12 can preferably be a standard part such as a screw or a bolt for easy procurement. The lower limit member 12 is connected to the mounting plate 3 through a threaded hole, and the position of the lower limit member 12 can be changed according to actual conditions to adapt to different working conditions.

[0033] The linkage member 9 includes a first connection block 9a and a second connection block 9b which are detachably connected to each other by screws, a receiving groove structure 9c which is sleeved on the outer periphery of the hot riveting member 1 is provided between the first connection block 9a and the second connection block 9b, and the second connection block 9b is fixedly connected to the slider 10. The linkage member 9 is provided as a split first connection block 9a and a second connection block 9b, so as to facilitate the assembly of the linkage member 9 and the hot riveting member 1. At the same time, during the assembly, the gap between the first connection block 9a and the second connection block 9b can be changed according to the specification type of the hot riveting member 1 to adapt to hot riveting members 1 of different specifications and types.

[0034] The outer periphery of the heat riveted component 1 is provided with two sets of washers 13 symmetrically attached to the outer periphery of the heat riveted component 1, and the lower end of the washers 13 is provided with a stopper 13a. The washers 13 can replace the heat riveted component 1 to contact the linkage component 9 to avoid excessive wear between the heat riveted component 1 and the linkage component 9. When the washers 13 are installed, the stopper 13a plays a positioning role.

[0035] The outer periphery of the mounting plate 3 is connected with a protective sleeve 14 to protect the slider 10, the slide rail 11, the spring 5, the floating rod 4, the linkage member 9 and other components.

[0036] Working principle of this embodiment: The multi-axis manipulator 2 drives the hot riveting part 1 to move through the mounting plate 3. When the hot riveting part 1 moves down to press the fabric, the hot riveting part 1 will move upward under the structural cooperation of the slider 10 and the slide rail 11, and will squeeze the anti-drop cap during the movement, that is, squeeze the floating rod 4, and the spring 5 will also be squeezed. After completing the downward pressing work, the multi-axis manipulator 2 drives the mounting plate 3 to move upward. At this time, the spring 5 releases the restoring force, and the hydraulic pressure in the piston sleeve 6 also releases part of the pressure. The hot riveting part 1 will not move up immediately until the floating rod 4 no longer moves relative to the piston sleeve 6, and the hot riveting part 1 will follow the multi-axis manipulator 2 to move up.

[0037] In the hot riveting process of this embodiment, the hot riveting part 1 can float in the vertical direction under the action of the floating rod 4, spring 5 and other parts. When the hot riveting part 1 encounters fabrics of different thicknesses or uneven surfaces of parts such as column trims, the cooperation of the floating rod 4 and the spring 5 can make the hot riveting part 1 automatically adjust its position to ensure that the contact between the hot riveting part 1 and the fabric is more uniform and tight, avoiding excessive heating of the fabric or loose contact with the column trim. The elastic force of the spring 5 can automatically adjust the pressure applied by the hot riveting head to the fabric. When the hot riveting head encounters resistance or obstacles, the spring 5 can absorb part of the impact force to prevent damage to the hot riveting head.
