Description

Technical Field

[0001] The invention relates to the technical field of seat belt brackets, in particular to a positioning and punching device for a seat belt bracket. Background Art

[0002] Automobile seat belts are safety devices used to restrain passengers in a collision and to prevent passengers from having secondary collisions with the steering wheel, dashboard, etc., or from being thrown out of the car and causing death or injury. In existing vehicles, seat belts are mostly placed behind the seats. When passengers use seat belts, they need to pull out the seat belts behind the seats significantly, which is very inconvenient. Therefore, in the prior art, there is a seat belt bracket fixed at the neck of the backrest, which can limit the position of the seat belt and make it convenient for people to pull out the seat belt for use.

[0003] During the production and processing of the seat belt bracket, a through hole is opened on the seat belt bracket to facilitate the installation of the seat belt bracket on the backrest. In the prior art, when punching holes in the seat belt bracket, people need to manually control the position of the seat belt bracket relative to the positioning mold, which is a cumbersome operation. At the same time, when the seat belt bracket is placed in the mold, it is necessary to control the two molds again to position and clamp the seat belt bracket before controlling the punching device to punch holes in the seat belt bracket. The process is cumbersome. Summary of the invention

[0021] like Figures 1 to 4 As shown, fixed blocks 7 are symmetrically fixedly installed on both sides of the middle placement table of the workbench 1, and a limiting rod 8 is fixedly installed between the two fixed blocks 7. The positioning mold 4 has a limiting hole 9 corresponding to the position of the limiting rod 8, and the limiting hole 9 is slidably connected to the limiting rod 8.

[0022] The movement of the positioning mold 4 can be limited by the limiting rod 8 .

[0023] like Figures 1 to 4As shown, an extrusion block 10 is fixedly installed on the movable end of the hydraulic rod 2, and extrusion slopes 11 are provided at both ends of the extrusion block 10. A trapezoidal block 12 is fixedly installed on the top of the positioning mold 4, and the slope of the trapezoidal block 12 is in extrusion contact with the extrusion slope 11. Reset springs 13 are symmetrically sleeved on both ends of the limit rod 8, one end of the reset spring 13 is fixedly connected to the fixed block 7, and the other end of the reset spring 13 is fixedly connected to the positioning mold 4. The punching rod 3 is fixedly installed in the middle position of the extrusion block 10.

[0024] The extrusion block 10 is driven down by the hydraulic rod 2, and the extrusion slope 11 on the extrusion block 10 will extrude the slope of the trapezoidal block 12, which will drive the two positioning dies 4 to move toward each other along the two limit rods 8, and the seat belt bracket will be extruded and positioned. The seat belt bracket will be inside the storage hole 5. The extrusion block 10 continues to descend and will drive the punching rod 3 to extrude the seat belt bracket. When the two positioning dies 4 are in contact, the punching rod 3 will be driven to punch the seat belt bracket, which is used for punching holes in the seat belt bracket. The punching operation of the seat belt bracket can be completed while the seat belt bracket is positioned, and the operation is simple.

[0025] like Figures 1 to 4 As shown, a sliding hole 14 is opened in the middle of the punching rod 3, and an extrusion rod 15 is slidably installed inside the sliding hole 14. A push spring 16 is fixedly installed on the top of the extrusion rod 15, and the top of the push spring 16 is fixedly connected to the top of the inner wall of the punching rod 3.

[0026] After the punching is completed, the hydraulic rod 2 drives the extrusion block 10 to rise, and the extrusion rod 15 is pushed by the push spring 16 to drive the punched ring to fall from the safety belt bracket or the inside of the punching rod 3.

[0027] like Figures 1 to 4 As shown, a first rack 17 is fixedly installed in the middle of the positioning mold 4, and a mounting block 18 is fixedly installed at the position of the first rack 17 on the middle placement table of the working frame 1, and a gear 19 is rotatably installed on one side of the mounting block 18 through an axle pin, and the gear 19 is meshingly connected with the first rack 17. A slide groove 20 is opened at the middle placement table of the working frame 1, and a second rack 21 is slidably installed inside the slide groove 20, and the second rack 21 is meshingly connected with the gear 19, and the support block 6 is fixedly installed at the end of the second rack 21.

[0028] When the two positioning molds 4 move toward each other, the first rack 17 will be driven to move, and the gear 19 will be driven to rotate through the meshing of the gear 19 and the first rack 17, and the second rack 21 will be driven to slide inside the slide groove 20 through the meshing of the gear 19 and the second rack 21. The support of the support block 6 for the seat belt bracket will be cancelled, and the perforation in the middle of the positioning mold 4 will be exposed.

[0029] like Figures 1 to 4 As shown, a material unloading chute 22 is provided in the middle of the working frame 1 .

[0030] The present invention provides a positioning and punching device for a safety belt bracket, and the specific working principle is as follows:

[0031] When the device is in use, the safety belt bracket is placed on the top of the support block 6 between the two positioning molds 4, and the extrusion block 10 is driven down by the hydraulic rod 2. The extrusion inclined surface 11 on the extrusion block 10 will squeeze the inclined surface of the trapezoidal block 12, which will drive the two positioning molds 4 to move toward each other along the two limit rods 8, and the safety belt bracket will be squeezed and positioned. The safety belt bracket will be inside the storage hole 5. At this time, the reset spring 13 is in an elongated state. When the two positioning molds 4 move toward each other, the first rack 17 will be driven to move, and the gear 19 and the first The meshing of the rack 17 will drive the gear 19 to rotate, and the meshing of the second rack 21 with the gear 19 will drive the second rack 21 to slide inside the slide groove 20, which will cancel the support of the support block 6 for the seat belt bracket, and the perforation in the middle of the positioning mold 4 will be exposed. During the process of the two positioning molds 4 extruding and positioning the seat belt bracket, the extrusion block 10 will continue to descend and drive the punching rod 3 to extrude the seat belt bracket. When the two positioning molds 4 contact, the punching rod 3 will be driven to perform a punching operation on the seat belt bracket, which is used for punching holes in the seat belt bracket.

[0032] After the punching is completed, the extrusion block 10 is driven to rise by the hydraulic rod 2, and the positioning mold 4 is pulled by the reset spring 13 to drive the positioning mold 4 to move backwards along the two limit rods 8, thereby canceling the positioning of the seat belt bracket. At the same time, the push of the extrusion rod 15 by the push spring 16 will drive the punched ring to fall from the seat belt bracket or the inside of the punching rod 3.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
