Description

Technical Field

[0001] This utility model relates to the technical field of headrest bar punching equipment, and in particular to an adjustable automotive headrest bar punching mechanism. Background Technology

[0002] By using a grooving machine to create grooves on the side of the car headrest rod, and locking them with positioning pins on the side of the seat, the height of the headrest can be adjusted to accommodate different passenger heights, thus improving seat comfort. However, current grooving machines can only continuously punch grooves of the same depth on the side of the headrest rod, and cannot flexibly control the depth of the grooving.

[0003] For example, Chinese utility model patent CN211491864U discloses an automatic grooving and punching mechanism, including a punching groove, a punching fixing device, and a punching mold. Both sides of the punching groove are provided with punching groove panel support blocks, and a slide rail is provided on the right side of the punching groove panel support blocks. Although this solution improves the efficiency of punching and grooving by having the punch, upper punching mold base, and lower punching mold base work together to move left and right, the depth of the grooving varies depending on the car model, seat specifications, or the design of the headrest rod side locking pin. If the depth of the grooving on the headrest rod needs to be adjusted, the punch and other mold components need to be replaced, which is very inconvenient. Therefore, an adjustable automotive headrest rod grooving mechanism is proposed. Utility Model Content

[0004] To address the technical problem of inconvenient groove depth adjustment in headrest bar grooving equipment, this utility model provides an adjustable automotive headrest bar grooving mechanism.

[0005] This utility model is achieved using the following technical solution: an adjustable automotive headrest bar punching mechanism, comprising two mounting plates, with multiple load-bearing plates fixedly connected between the two mounting plates. Each load-bearing plate has a sliding rod below it, which is fixedly connected between the two mounting plates. Each sliding rod has a slidably connected limit block, and each limit block has a punch limiting mechanism on its upper side. Each limit block has a rotatably connected threaded rod on its lower side, with the upper end of each threaded rod passing upward through the limit block and threadedly fitted with a punch. Each threaded rod has a fixedly connected handwheel knob at its lower end. Each load-bearing plate has a headrest bar punching mechanism. A punch driving mechanism for reciprocating left and right movement of the punch is provided between the two mounting plates below. Each load-bearing plate has a headrest bar positioning mechanism on its upper side.

[0006] As a further improvement to the above solution, the headrest bar punching mechanism includes a slot opened on each of the load-bearing plates, a limit pin slidably connected to the inner side of each slot, a punch fixedly connected to the upper end of each limit pin, and an elastic collision mechanism provided at the lower end of each limit pin.

[0007] As a further improvement to the above solution, the elastic collision mechanism includes a spherical push block that is fixedly connected to the lower end of each of the limiting pins. A spring is sleeved on the outer side of each of the limiting pins. The upper end of each spring is fixedly connected to the lower side of the load-bearing plate, and the lower end of the spring is fixedly connected to the upper side of the spherical push block. Each spherical push block is respectively configured to cooperate with the impact hammer.

[0008] As a further improvement to the above solution, the hammer limiting mechanism includes multiple limiting rods that are slidably connected to the upper side of each limiting block, and the upper ends of the multiple limiting rods are simultaneously fixedly connected to the lower side of the hammer.

[0009] As a further improvement to the above solution, the hammer drive mechanism includes a plurality of motors mounted on the outside of one of the mounting plates, the output end of each motor passing through the mounting plate, and the output end of each motor being fixedly connected to a lead screw that is threadedly engaged with the limit block.

[0010] As a further improvement to the above solution, the headrest rod positioning mechanism includes two mold bases fixedly connected to the upper side of each of the load-bearing plates. The two mold bases are located on both sides of the punch. Two coordinate moving modules are provided on the upper side of the two mounting plates. Two electric grippers are installed on the lower side of the two coordinate moving modules. Each electric gripper is configured to cooperate with each mold base.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model achieves the effect of pushing the punch upward by rotating the handwheel knob and pushing the threaded rod upward with the cooperation of multiple limit rods. When the punch collides with the spherical push block, it can adjust the upward punching distance between the limit pin and the punch.

[0013] 2. This utility model uses the method of impacting the spherical push block with the punch to squeeze the limiting pin upward. At the same time, the punch is installed on the upper end of the limiting pin. When the punch is worn and needs maintenance, it can be replaced directly from above the load-bearing plate. It has the significant advantages of easy maintenance and long service life. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example:

[0023] Please combine Figures 1-5 This embodiment of an adjustable car headrest bar slotting mechanism includes two mounting plates 2. In this embodiment, four load-bearing plates 4 are fixedly connected between the two mounting plates 2. Each load-bearing plate 4 represents a different position for the headrest bar slotting. A sliding rod 9 is provided below each load-bearing plate 4, and the sliding rod 9 is fixedly connected between the two mounting plates 2. A limit block 8 is slidably connected to each sliding rod 9. A punch limiting mechanism is provided on the upper side of each limit block 8. A threaded rod 17 is rotatably connected to the lower side of each limit block 8. The upper end of each threaded rod 17 passes upward through the limit block 8 and is threadedly sleeved with a punch 7. Figure 3 As shown, the punch 7 has a protrusion structure, which can squeeze the spherical push block 14. Each threaded rod 17 is fixedly connected to a handwheel knob 15 at its lower end. When the handwheel knob 15 is turned, it can drive the threaded rod 17 to rotate. Each load-bearing plate 4 is provided with a headrest rod punching mechanism. Between the two mounting plates 2, there is a punch drive mechanism that makes the punch 7 move back and forth. Each load-bearing plate 4 is provided with a headrest rod positioning mechanism on its upper side.

[0024] With the above technical solution, when the handwheel knob 15 is turned, the hammer 7 can move upward relative to the limit block 8 under the limiting action of the limit rod 16.

[0025] Please combine Figure 5 As shown, the headrest rod punching mechanism includes slots opened on each load-bearing plate 4. Each slot has a slidable limit pin 12 inside. The side of the limit pin 12 is designed with a retaining plate structure to prevent the limit pin 12 from rotating during the upward push. The upper end of each limit pin 12 is fixedly connected with a punch 6. The punch 6 and the limit pin 12 are detachable. When the punch 6 needs to be replaced, it can be released through the positioning bolt on the side of the limit pin 12. The lower end of each limit pin 12 is provided with an elastic collision mechanism.

[0026] Please combine Figure 5 As shown, the elastic collision mechanism includes a spherical push block 14 that is fixedly connected to the lower end of each limit pin 12. The spherical push block 14 is a metal iron block structure with excellent wear resistance and pressure resistance. A spring 13 is sleeved on the outside of each limit pin 12. The upper end of each spring 13 is fixedly connected to the lower side of the load-bearing plate 4, and the lower end of the spring 13 is fixedly connected to the upper side of the spherical push block 14. Each spherical push block 14 is respectively matched with the impact hammer 7.

[0027] Please combine Figure 4 As shown, the hammer limiting mechanism includes four limiting rods 16 that are slidably connected to the upper side of each limiting block 8, and the upper ends of the four limiting rods 16 are simultaneously fixedly connected to the lower side of the hammer 7.

[0028] Through the above technical solution, when the threaded rod 17 is rotated, it can push the punch 7 to the next position, and at the same time, it can more accurately control the height of the punch 7, thereby indirectly adjusting and controlling the groove depth.

[0029] Please combine Figure 3 As shown, the hammer drive mechanism includes multiple motors 1 mounted on the outside of one of the mounting plates 2. Each motor 1 corresponds to a lead screw 3. The output end of each motor 1 passes through the mounting plate 2, and the output end of each motor 1 is fixedly connected to a lead screw 3 that is threadedly connected to the limit block 8.

[0030] Please combine Figure 1 As shown, the headrest rod positioning mechanism includes two mold bases 5 that are fixedly connected to the upper side of each load-bearing plate 4. The two mold bases 5 are located on both sides of the punch 6. Two coordinate moving modules 10 are provided on the upper side of the two mounting plates 2. Two electric grippers 11 are installed on the lower side of the two coordinate moving modules 10. Each electric gripper 11 is configured to cooperate with each mold base 5.

[0031] It should be noted that the two-axis moving module 10 can move back and forth along the direction of the mounting plate 2, and can also control the lifting height of the two electric grippers 11. When the headrest rod is placed on the two mold bases 5, the electric grippers 11 can press the headrest rod from above.

[0032] The implementation principle of the adjustable car headrest bar grooving mechanism in this application embodiment is as follows: Before grooving, the handwheel knob 15 is manually turned to drive the threaded rod 17 to rotate. At this time, under the action of multiple limit rods 16, the threaded rod 17 pushes the punch 7 to move upward to a certain height, thus completing the function of setting the headrest bar grooving depth. Then, the two-coordinate moving module 10 drives two electric grippers 11 to move the headrest bar and place it on two mold bases 5, pressing it downward to fix it. Then, the motor 1 is started to drive the lead screw 3 to rotate at high speed, which drives the limit block 8 to push the punch 7 to move to one side at high speed. The punch 7 collides with the spherical push block 14 and directly pushes the spherical push block 14 and the punch 6 upward, thereby realizing the function of grooving the headrest bar that has been positioned by the electric grippers 11 and the mold base 5.

[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
