Description

Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing technology, and in particular relates to a positioning fixture for opening holes in automotive electrical brackets. Background Technology

[0002] Automotive electrical brackets are devices used in automotive electrical systems to fix, support, and organize various electrical components and wiring harnesses. The shape and structure of electrical brackets can be customized according to the characteristics of the vehicle's interior space, making full use of limited space and improving the utilization rate of vehicle space.

[0003] Holes are drilled on the surface of the bracket to serve as mounting positions for bolts, rivets, and other connectors, enabling the bracket to be fixed to other components and ensuring installation accuracy. During the drilling process, operators often manually support the bracket to easily change the hole position. To enhance the fixing and limiting effect of the bracket during the drilling process, a positioning fixture for drilling holes in automotive electrical brackets was designed. This fixture, using a servo motor, allows the clamping device to flexibly fix and release the bracket body, thereby ensuring that the bracket can flexibly change the hole position while achieving a better fixing effect. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning clamp for opening holes in automotive electrical brackets, which can ensure that the bracket can flexibly change the position of the opening while achieving a better fixing effect, thereby solving the aforementioned technical problems.

Two limit grooves are opened on the top of the support plate, and the surfaces of the limit strips are slidably connected to the inner cavity of the limit grooves. A slotted housing is fixedly connected to the top of the support platform by bolts, the support plate is located in the inner cavity of the slotted housing, two L-shaped plates are slidably connected to the top of the slotted housing, the bottoms of the two L-shaped plates are respectively welded to the tops of the two racks, and an H-shaped lifting member is welded to the top of the slotted housing.

[0006] Preferably, rubber pads are fixedly connected to opposite sides of the L-shaped plate, and guide blocks are welded to both the front and rear sides of the L-shaped plate.

[0007] Preferably, guide grooves are provided on both the front and rear sides of the inner cavity of the H-shaped lifting member, and the surface of the guide block is slidably connected to the inner cavity of the guide groove.

[0024] In the following description, embodiments of the positioning clamp for opening holes in automotive electrical brackets according to the present invention will be described with reference to the accompanying drawings.

[0025] Example 1:

[0026] Figure 1-6 This invention illustrates a positioning fixture for opening holes in an automotive electrical bracket, comprising a support platform 1. A support plate 2 is bolted to the top of the support platform 1. A gear 3 is rotatably connected to the top of the support plate 2. Two racks 4 are slidably connected to the top of the support plate 2, meshing with the surfaces of the gears 3. Limiting strips 5 are welded to the bottom of each rack 4. Two limiting grooves 6 are formed on the top of the support plate 2, with the surfaces of the limiting strips 5 slidably connected to the inner cavities of the limiting grooves 6. A slotted housing 7 is bolted to the top of the support platform 1, with the support plate 2 located within the inner cavity of the slotted housing 7. Two L-shaped slots slidably connect to the top of the slotted housing 7. The bottom of the two L-shaped plates 8 are welded to the top of the two racks 4 respectively. The top of the slotted housing 7 is welded with an H-shaped lifting member 9. Rubber pads 10 are fixedly connected to the opposite side of the two L-shaped plates 8. The rubber pads 10 make the contact surface between the support surface and the L-shaped plates 8 softer, and can avoid the L-shaped plates 8 from damaging the support surface. Guide blocks 11 are welded to the front and rear sides of the L-shaped plates 8. Guide grooves 12 are opened on the front and rear sides of the inner cavity of the H-shaped lifting member 9. The surface of the guide block 11 is slidably connected to the inner cavity of the guide groove 12. The inner cavity of the support platform 1 is fixedly connected with a servo motor 14 by bolts.

[0027] Example 2:

[0028] Figure 1-6This invention illustrates a positioning fixture for opening holes in an automotive electrical bracket, comprising a support platform 1. A support plate 2 is bolted to the top of the support platform 1. A gear 3 is rotatably connected to the top of the support plate 2. Two racks 4 are slidably connected to the top of the support plate 2, meshing with the surfaces of the racks 4 and gears 3. Limiting strips 5 are welded to the bottom of each rack 4. Two limiting grooves 6 are formed on the top of the support plate 2, with the surfaces of the limiting strips 5 slidably connected to the inner cavities of the limiting grooves 6. A slotted housing 7 is bolted to the top of the support platform 1, with the support plate 2 located within the inner cavity of the slotted housing 7. Two... L-shaped plates 8 are welded to the top of two racks 4 at their bottoms. H-shaped lifting parts 9 are welded to the top of the slotted housing 7. Two placement plates 13 are fixedly connected to the top of the support platform 1 by bolts. The two placement plates 13 are located on the front and rear sides of the slotted housing 7, respectively. The height of the placement plates 13 is the same as the height of the H-shaped lifting parts 9. By setting the placement plates 13, the support can get additional support after being placed on the top of the H-shaped lifting parts 9, which can make the support more stable during the drilling process. The output shaft of the servo motor 14 is fixedly connected to the gear 3 through a flange. A drilling machine 15 is installed on the top of the support platform 1.

[0029] Working principle: When using this utility model, the user places the bracket on top of the H-shaped lifting member 9, and the placement plate 13 can provide better support for the bracket. Then, the servo motor 14 is started to drive the gear 3 to rotate. At this time, the meshing action of the gear 3 pulls the two racks 4 to slide relative to each other, which in turn drives the two L-shaped plates 8 to slide relative to each other, thereby clamping and fixing the bracket body. Then, the drilling machine 15 is used to drill holes on the surface of the bracket. When it is necessary to change the position of the hole, the servo motor 14 again causes the two racks 4 to drive the L-shaped plates 8 to slide back and forth, thereby releasing the restriction on the position of the bracket. This ensures that the bracket can flexibly change the position of the hole while achieving a better fixing effect.

[0030] In summary, the positioning fixture for the opening of the automotive electrical bracket uses the servo motor 14 to drive the gear 3 to rotate, which in turn drives the two L-shaped plates 8 to slide relative to each other via the rack 4, thereby clamping and fixing the bracket body. This achieves a better fixing effect while ensuring that the bracket can flexibly change the opening position.
