Description

Technical Field

[0001] This utility model relates to the field of automotive cushion technology, specifically a cushion punching device. Background Technology

[0002] A car seat cushion is a protective pad placed on a car seat to increase comfort and protect it from damage. Car seat cushions are usually made of soft materials such as cotton or fleece, which have good breathability and moisture absorption. They effectively reduce pressure on the back during long drives and provide good support and cushioning, protecting the lumbar and cervical spine. Car seat cushions can also be chosen in different colors and styles to add a decorative and aesthetic touch to the car interior.

[0003] To ensure the breathability of car cushions, existing technologies use perforation equipment to punch holes in the cushions. The common method is to use a laser drilling machine to punch holes in the car cushions placed on the perforation platform. This is convenient and quick. However, because car cushions have a certain degree of flexibility, they may bend and become uneven when placed on the perforation platform, requiring manual smoothing, which is a rather cumbersome process.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4As shown in this embodiment, a cushion punching device includes a processing table 1. A placement plate 2 is fixedly installed in the middle of the processing table 1. Clamping frames 3 are symmetrically slidably installed on the upper surface of the processing table 1. The two clamping frames 3 can move back to back and towards each other. A rotating shaft 4 is symmetrically rotatably installed in the middle of the clamping frame 3.

The clamping rollers 5 can slide on the rotating shaft 4 and rotate with the rotating shaft 4. A laser punching assembly 6 is movably installed above the processing table 1. The laser punching assembly 6 is the same as the existing laser assembly for punching car cushions in terms of its working principle. The laser punching assembly 6 can perform X-ray punching, The Y-axis moves, and a controller 24 is fixedly installed on one side of the processing table 1. The car cushion is placed on the placement plate 2, and the two ends of the car cushion are clamped between two clamping rollers 5 on two rotating shafts 4. Then, the two clamping frames 3 move in opposite directions to straighten the car cushion and control the vertical flatness of the car cushion. During the movement of the clamping frames 3, the two clamping rollers 5 on the rotating shaft 4 move in opposite directions. Since the car cushion is clamped and fixed between the two clamping rollers 5, the movement of the clamping rollers 5 will straighten the car cushion, keep the surface of the car cushion smooth, and prevent the car cushion from wrinkling. Then, the laser drilling component 6 is controlled to move along the X and Y axes to perform drilling operations on the entire car cushion.

[0022] like Figures 1 to 4 As shown, a bidirectional screw 7 is symmetrically mounted on the middle part of the processing table 1 via bearings. A first motor 8 is fixedly mounted on the processing table 1 at the end position corresponding to the bidirectional screw 7. The output end of the first motor 8 is fixedly connected to one end of the bidirectional screw 7. The clamping frame 3 is threadedly connected to both bidirectional screws 7.

[0023] The first motor 8 drives the bidirectional screw 7 to rotate. The clamping frame 3 is simultaneously connected to the two bidirectional screws 7 by threads and the limiting effect will drive the two clamping frames 3 to move in opposite directions.

[0024] like Figures 1 to 4 As shown, the outer side of the rotating shaft 4 is fixedly mounted with the central axis of the rotating shaft 4 in a ring array. The outer side of the clamping roller 5 is provided with a sliding groove 10 in a ring array with the central axis of the clamping roller 5 as the axis. The sliding groove 10 is slidably connected to the sliding block 9.

[0025] When the second motor 12 drives the two rotating shafts 4 to rotate in opposite directions, the mutual locking of the slide groove 10 and the slider 9 will drive the two clamping rollers 5 on the two rotating shafts 4 to rotate synchronously in opposite directions. During the movement of the clamping frame 3, the sliding limit of the slide groove 10 and the slider 9 can drive the two clamping rollers 5 on the rotating shaft 4 to move in opposite directions on the rotating shaft 4.

A second motor 12 is fixedly installed at one end of the clamping frame 3 corresponding to the position of one of the rotating shafts 4, and the output end of the second motor 12 is fixedly connected to one end of the rotating shaft 4.

[0027] The second motor 12 drives one of the rotating shafts 4 to rotate, and the meshing connection between the gears 11 on the two rotating shafts 4 will drive the two rotating shafts 4 to rotate in opposite directions.

[0028] like Figures 1 to 4 As shown, a return spring 13 is sleeved on the outer side of one end of the rotating shaft 4. One end of the return spring 13 is fixedly connected to one end of the clamping roller 5, and the other end of the return spring 13 is fixedly connected to the outer side of the rotating shaft 4. A first extrusion slope 14 is provided at the end of the clamping roller 5 away from the return spring 13. A fixing block 15 is fixedly installed at the middle position on the placement plate 2. A second extrusion slope 16 is provided at the end of the fixing block 15. The second extrusion slope 16 is in extrusion contact with the first extrusion slope 14.

[0029] During the movement of the clamping frame 3, the first extrusion slope 14 on the clamping roller 5 will extrude the second extrusion slope 16 on the fixing block 15, which will drive the two clamping rollers 5 on the rotating shaft 4 to move in opposite directions on the rotating shaft 4.

[0030] like Figures 1 to 4 As shown, the top two sides of the processing table 1 are symmetrically mounted with bearings for the first linear screw 17. The processing table 1 is fixedly mounted with a third motor 18 at the end position corresponding to the first linear screw 17. The output end of the third motor 18 is fixedly connected to one end of the first linear screw 17. A movable frame 19 is threadedly mounted between the two first linear screws 17. The laser drilling assembly 6 is slidably mounted in the middle of the movable frame 19.

[0031] The third motor 18 drives the first linear screw 17 to rotate. The two first linear screws 17 are connected to the moving frame 19 by threads and mutually limit each other, which will drive the moving frame 19 to move along the Y-axis.

[0032] like Figures 1 to 4 As shown, a guide rail 20 is fixedly installed at the top of the movable frame 19, and a mounting base 21 is slidably installed on the guide rail 20.

[0034] This utility model provides a cushion punching device, the specific working principle of which is as follows:

[0035] In use, the car cushion is placed on the placement plate 2, with both ends of the cushion aligned between the two clamping rollers 5 on the two rotating shafts 4. The second motor 12 drives one of the rotating shafts 4 to rotate. The meshing connection between the gears 11 on the two rotating shafts 4 causes them to rotate in opposite directions. The interlocking of the slide groove 10 and the slider 9 causes the two clamping rollers 5 on the two rotating shafts 4 to rotate synchronously in opposite directions, clamping both ends of the car cushion between the two clamping rollers 5 on the two rotating shafts 4. Then, the first motor 8 drives the bidirectional screw 7 to rotate. The simultaneous threaded connection and limiting action between the clamping frame 3 and the two bidirectional screws 7 causes the two clamping frames 3 to move in opposite directions, straightening the car cushion and controlling its vertical flatness. During the movement of the clamping frames 3, the first pressing slope 14 on the clamping roller 5 presses against the second pressing slope 16 on the fixing block 15, thus straightening the car cushion. The two clamping rollers 5 on the rotating shaft 4 move in opposite directions. Since the car cushion is clamped and fixed between the two clamping rollers 5, the movement of the clamping rollers 5 will straighten the car cushion, keep the surface of the car cushion smooth, and prevent the car cushion from wrinkling. At this time, the return spring 13 is in a compressed state. Then, the operation of the laser drilling component 6 can perform drilling operation on the car cushion. During the drilling process, the third motor 18 drives the first linear screw 17 to rotate. Through the threaded connection between the two first linear screws 17 and the moving frame 19 and their mutual limiting, the moving frame 19 will be driven to move along the Y-axis. The fourth motor 23 drives the second linear screw 22 to rotate. Through the threaded connection between the mounting base 21 and the second linear screw 22, the mounting base 21 will be driven to move along the X-axis along the trajectory of the guide rail 20. The laser drilling component 6 can be controlled to move along the X and Y axes to perform drilling operation on the entire car cushion.

[0036] After the drilling is completed, the second motor 12 drives the rotating shaft 4 to rotate. The meshing connection between the gears 11 on the two rotating shafts 4 will drive the two rotating shafts 4 to rotate in opposite directions, so that the car cushion can slide out from between the two clamping rollers 5 on the two rotating shafts 4 for unloading the car cushion.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
