Description

Technical Field

[0001] The utility model specifically relates to a column reverse batching device. Background Art

[0002] In automobile interior design, pillars, as an important part of the body structure, not only play the key role of supporting the body frame and ensuring safety, but the covering fabric on their surface also plays a vital role in improving the overall texture and aesthetics of the interior.

[0003] For example, the Chinese utility model patent document with the publication number "CN218892239U" discloses a device for reverse wrapping fabric of a column trim, 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 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, 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, 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.

[0004] The anti-packaging device has the following defects:

[0005] First, 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. The hot riveting action is "rigid contact", and it is extremely difficult to control the pressure exerted by the hot riveting block on the fabric. Therefore, 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 leads to damage to the hot riveting block.

[0006] Secondly, the outer periphery of the lower mold is surrounded by a side heat pressing mechanism, and the position of each set of side heat pressing mechanisms relative to the lower mold is fixed and cannot be adjusted. Therefore, it cannot be adjusted according to the size, shape or thickness of the column trim, and the adaptability is poor. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide a column reverse batching 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 decorative plate, while protecting the hot riveted parts.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a column reverse batching equipment, comprising a frame, on which at least one group of lower molds and a multi-axis manipulator are provided, the end of the multi-axis manipulator is linked with a hot riveting device, and the side of the lower mold is provided with a side hot pressing device, the hot riveting device comprises a mounting plate and a hot riveting part, and the mounting plate is linked with the multi-axis manipulator, and is characterized in that: the hot riveting part is slidably connected to the mounting plate, a floating rod is provided above the hot riveting part, the floating rod is slidably connected to the mounting plate, and a spring is provided on the outer peripheral sleeve of the floating rod, and the spring is distributed between the hot riveting part and the mounting plate.

[0009] 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.

[0010] The above-mentioned column reverse batching equipment 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.

[0011] 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.

[0012] The above-mentioned column reverse batching equipment can be further configured as follows: one end of the lower mold is provided with a pushing cylinder and a push plate linked to the output end of the pushing cylinder, the body of the pushing cylinder is fixed on the frame, the push plate is detachably connected with a positioning piece, and the positioning piece is provided with a profiling block that is shaped like the end of the column.

[0013] By adopting the above technical solution, the push plate can be moved by pushing the cylinder, and the position of the push plate can be adjusted according to the size and shape of the column, so that the equipment can adapt to columns of different sizes and shapes, which significantly improves the versatility and flexibility of the equipment. The positioning member is provided with a profiling block that is contoured to the end of the column to ensure that the push plate fits tightly with the end of the column trim, and even when the shape of the end of the column trim is complex, accurate positioning and limiting can be achieved.

[0015] With the above technical solution, the push plate limits one end of the column, and the pressure hammer rotates to the top of the column driven by the rotating cylinder to limit the other end of the column. The downward movement angle of the pressure hammer can be changed according to actual conditions by driving the rotating cylinder to adapt to columns of different specifications and types.

[0016] The above-mentioned column reverse batching equipment can be further configured as follows: the hot riveting part is detachably and fixedly connected with a linkage part, the linkage part is fixedly connected with a first slider, the first slider is slidably matched with a second slide rail, and the second slide rail is fixed on the mounting plate.

[0017] By adopting the above technical solution, when the hot riveted component is floating, the first slider, the second slide rail and the linkage cooperate with each other to guide the hot riveted component in sliding, ensuring that the floating path of the hot riveted component is always unique, while realizing the sliding connection between the hot riveted component and the mounting part.

[0018] The above-mentioned column reverse batching equipment 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.

[0019] 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.

[0021] 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.

[0022] The above-mentioned column reverse batching equipment can be further configured as follows: a protective sleeve is connected to the outer periphery of the mounting plate.

The end of the multi-axis manipulator 2 is linked with a hot riveting device, and the side of the lower mold 15 is provided with a side hot pressing device.

[0038] One end of the lower mold 15 is provided with a push cylinder 16 and a push plate 17 linked to the output end of the push cylinder 16. The body of the push cylinder 16 is fixed on the frame. The push plate 17 is detachably connected with a positioning member 18, and the positioning member 18 is provided with a profiling block 19 that is shaped like the end of the column. By driving the push plate 17 to move by the push cylinder 16, the position of the push plate 17 can be adjusted according to the size and shape of the column, so that the equipment can adapt to columns of different sizes and shapes, significantly improving the versatility and flexibility of the equipment. The positioning member 18 is provided with a profiling block 19 that is shaped like the end of the column, ensuring that the push plate 17 is tightly fitted with the end of the column trim, and even when the shape of the end of the column trim is complex, accurate positioning and limiting can be achieved.

A floating rod 4 is provided above the hot riveting part 1, and the floating rod 4 is slidably connected with the mounting plate 3. The outer peripheral sleeve of the floating rod 4 is provided with a spring 5, and the spring 5 is distributed between the hot riveting 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 with a limited position nut 7, and the lower end of the floating rod 4 is connected with 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 riveting 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 the 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 component 1 from being impacted and damaged due to a sudden stop. The hot riveted component 1 is detachably fixedly connected with a linkage member 9, and the linkage member 9 is fixedly connected with a first slider 10. The first slider 10 is slidably matched with a second slide rail 24f11, and the second slide rail 24f11 is fixed on the mounting plate 3. When the hot riveted component 1 is floating, the first slider 10, the second slide rail 24f11, and the linkage member 9 cooperate with each other to slide and guide the hot riveted component 1, ensuring that the floating path of the hot riveted component 1 is always unique, and at the same time realizing the sliding connection between the hot riveted component 1 and the mounting component.

[0041] 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, which is convenient for procurement and has good interchangeability and is easy to repair and replace. 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.

[0042] 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 first slider 10. The linkage member 9 is provided as a split first connection block 9a and a second connection block 9b, which facilitates the assembly of the linkage member 9 and the hot riveting member 1. At the same time, during 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.

[0043] The outer periphery of the mounting plate 3 is connected with a protective cover 14 to protect the first slider 10, the second slide rail 24f11, the spring 5, the floating rod 4, the linkage member 9 and other components.

[0044] The side hot pressing device includes a first side hot pressing component 23 arranged near the end of the column and a second side hot pressing component 24 arranged in the middle of the column; the first side hot pressing component 23 includes a first positioning seat 23a fixed on the frame, a first longitudinal cylinder 23b is installed on the first positioning seat 23a, and the output end of the first longitudinal cylinder 23b is linked to the first transverse cylinder 23c; the second side hot pressing component 24 includes a second transverse cylinder 24a whose main body is fixed on the frame, the output end of the second transverse cylinder 24a is linked to a linkage plate 24b, and the two ends of the linkage plate 24b are respectively linked to a group of second positioning seats 24c, a second longitudinal cylinder 24d and a second slider 24e are fixed on the second positioning seat 24c, and the second slider 24e is slidably matched with a second slide rail 24f fixed on the frame, and the output ends of the first transverse cylinder 23c and the second longitudinal cylinder 24d are respectively linked to the side hot pressing block 25. The second transverse cylinder 24a in the second side heat pressing assembly 24 can drive at least two groups of side heat pressing blocks 25 to work through the linkage plate 24b, which not only improves the working synchronization of several groups of side heat pressing blocks 25 in the middle of the side of the column, but also reduces the cost. The first side heat pressing assembly 23 and the second side heat pressing assembly 24 cooperate with each other to achieve heat pressing of the column fabric.

[0045] The working principle of this embodiment is as follows: the column with the fabric is placed on the lower mold 15, the push cylinder 16 drives the profiling block 19 to move forward through the push plate 17 until it presses against one end of the column, the rotary cylinder 20 drives the pressing hammer 22 to rotate through the connecting rod 21 until it presses against the other end of the column, and the side hot pressing device presses the edge of the fabric on the side of the column. 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 relative to the mounting plate 3 under the structural cooperation of the first slider 10 and the second slide rail 24f11, and will squeeze the anti-collision cap 8 during the movement, that is, squeeze the floating rod 4, and the spring 5 is also squeezed. After completing the 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 move up with the multi-axis manipulator 2. The hot riveting piece 1 follows the multi-axis manipulator 2 to press down various parts of the fabric.
