Description

Technical Field

[0001] This utility model relates to the field of positioning structure technology, specifically a positioning structure for drilling holes in automotive parts. Background Technology

[0002] Automotive parts refer to the components of various parts in a car, as well as the units that make up the overall automotive parts processing and the products that serve automotive parts processing. A square tube frame is one type of automotive part. Typically, square tube frames require drilling. The purposes of drilling are: 1. To relieve internal stress: Drilling holes in the frame disperses stress around the holes, preventing deformation under stress and ensuring more even stress distribution; 2. To provide passageways for wiring and conduits; 3. To reduce the overall vehicle weight.

[0003] However, in the existing technology, when drilling holes in the square tube beam of an automobile, the drill rod is generally used directly to drill the hole. The lack of a positioning structure makes it easy for deformation to occur around the hole during drilling, which is not conducive to practical application and operation.

[0004] Therefore, those skilled in the art provide a positioning structure for drilling holes in automotive parts to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a positioning structure for drilling automotive parts. This solves the problem mentioned in the background section where, when drilling holes in automotive square tube beams, the drill rod is typically used directly on the beam, lacking a positioning structure, which leads to deformation around the hole during drilling.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a positioning structure for drilling holes in automotive parts, comprising an L-shaped plate and a mold core, wherein a slot is provided on the outer side of the L-shaped plate, and a locking block is installed at one end of the mold core, the locking block being slidably installed inside the slot, and the mold core being installed on the outer side of the L-shaped plate through the cooperation between the locking block and the slot;

[0007] The L-shaped plate is equipped with a limiting box with openings at both the top and bottom. The locking block is slidably connected to the limiting box. The limiting box is equipped with a locking component inside, which is used to lock the locking block in place.

[0008] Through the above technical solution, by using the set mold core, when drilling holes in the automotive square tube beam, the automotive square tube beam is fitted onto the outside of the mold core. This provides stable support and positioning for the automotive square tube beam during the drilling process, thereby preventing deformation around the hole diameter. At the same time, by setting a locking component, the mold core can be quickly installed and removed, allowing the equipment to use different mold cores according to the model of the automotive square tube beam, which is beneficial to practical application and operation.

[0009] Preferably, the locking assembly includes two springs, a sliding plate, two limiting rods, and two limiting grooves. The springs are installed inside the limiting box. The sliding plate slides inside the limiting box and is fixedly connected to one end of the spring. Both ends of the sliding plate extend to the outside of the limiting box. The limiting rods are installed at both ends of the sliding plate. The limiting grooves are opened on the outside of the locking block. The ends of the limiting rods away from the sliding plate extend into the corresponding limiting grooves.

[0010] By using the above technical solution, one end of the limiting rod is inserted into the inside of the limiting groove, so that the locking block cannot slide out of the groove at will, thereby further increasing the installation stability between the mold core and the L-shaped plate.

[0011] Preferably, the top of the L-shaped plate has four fixing holes, and two reinforcing plates are installed on the top of the L-shaped plate.

[0012] The above technical solution allows the L-shaped plate to be installed in a designated position using fixing holes, thus facilitating the overall use of the equipment. At the same time, the reinforcing plate can increase the structural stability of the L-shaped plate.

[0013] Preferably, the outer side of the mold core is provided with positioning holes, and all positioning holes penetrate the mold core.

[0014] The above technical solution allows for drilling operations using the positioning hole in conjunction with the drill rod. Furthermore, since the positioning hole penetrates the mold core, drilling can be performed on both sides of the automotive square tube beam without flipping it over.

[0015] Preferably, the limiting box has two sliding grooves on the side near the card block, and the card block has two sliding strips installed on the side near the limiting box, and the sliding strips are slidably connected to the sliding grooves.

[0016] The above technical solution, by utilizing the cooperation between the slide bar and the slide groove, further increases the stability of the sliding connection between the mold core and the L-shaped plate.

[0017] Preferably, the end of the limiting rod away from the slide plate and the end of the locking block are both provided with mutually cooperating inclined structures.

[0018] Through the above technical solution, by utilizing the cooperation between the inclined surfaces, when installing the card block and the mold core, when the inclined surface at one end of the card block contacts the inclined surface at one end of the limiting rod, the card block continues to slide and install. Thus, by utilizing the action of the inclined surface, the limiting rod and the slide plate can be lifted and the spring can be squeezed. When the card block is installed to the designated position, under the action of the spring force, the slide plate and the limiting rod return to their original positions. At this time, the limiting rod enters the interior of the limiting groove, thus enabling the installation operation to be completed quickly.

[0019] This utility model provides a positioning structure for drilling holes in automotive parts, which has the following beneficial effects:

[0020] This positioning structure for drilling automotive parts uses a mold core. When drilling a square tube beam, the beam is fitted onto the outside of the mold core, providing stable support and positioning during the drilling process. This prevents deformation around the hole during drilling. Furthermore, the locking mechanism allows for quick installation and removal of the mold core, enabling the equipment to use different mold cores depending on the model of the square tube beam, which is beneficial for practical application and operation.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Reference Figures 1-4This utility model provides a positioning structure for drilling automotive parts, including an L-shaped plate 1 and a mold core 2. The top of the L-shaped plate 1 has four fixing holes 10, which allow the L-shaped plate 1 to be installed in a designated position, facilitating the overall use of the equipment. Two reinforcing plates 11 are installed on the top of the L-shaped plate 1, increasing its structural stability. The outer side of the mold core 2 has positioning holes 12, all of which penetrate the mold core 2. These positioning holes 12, when used with a drill rod, allow for drilling operations. Furthermore, because the positioning holes 12 penetrate the mold core 2, drilling can be performed on both sides of the automotive square tube beam without flipping it over.

[0028] The outer side of the L-shaped plate 1 is provided with a slot 3, and a locking block 4 is installed at one end of the mold core 2. The locking block 4 is slidably installed inside the slot 3. The mold core 2 is installed on the outer side of the L-shaped plate 1 through the cooperation between the locking block 4 and the slot 3. By utilizing the cooperation between the locking block 4 and the slot 3, the mold core 2 can be quickly slidably installed on the outer side of the L-shaped plate 1, so that the two can be used together.

[0029] A limiting box 5 with openings at both the top and bottom is installed on the outer side of the L-shaped plate 1. The locking block 4 is slidably connected to the limiting box 5. Two sliding grooves 13 are opened on the side of the limiting box 5 near the locking block 4. Two sliding strips 14 are installed on the side of the locking block 4 near the limiting box 5. The sliding strips 14 are slidably connected to the sliding grooves 13. The cooperation between the sliding strips 14 and the sliding grooves 13 further increases the stability of the sliding connection between the mold core 2 and the L-shaped plate 1.

[0030] In one aspect of this embodiment, a locking assembly is provided inside the limiting box 5 to lock the locking block 4 in place. The locking assembly includes two springs 6, a sliding plate 7, two limiting rods 8, and two limiting grooves 9. The springs 6 are installed inside the limiting box 5, and the sliding plate 7 slides inside the limiting box 5 and is fixedly connected to one end of the spring 6. The elastic force of the spring 6 allows the sliding plate 7 to return to its original position inside the limiting box 5. Both ends of the sliding plate 7 extend to the outside of the limiting box 5 for easy movement. The limiting rods 8 are installed at both ends of the sliding plate 7, and the limiting grooves 9 are formed on the outside of the locking block 4. The ends of the limiting rods 8 away from the sliding plate 7 extend into the corresponding limiting grooves 9. By inserting one end of the limiting rod 8 into the limiting groove 9, the locking block 4 cannot slide out of the slot 3 at will, thereby further increasing the installation stability between the mold core 2 and the L-shaped plate 1.

[0031] Both the end of the limiting rod 8 away from the slide plate 7 and the end of the locking block 4 have mutually cooperating inclined surfaces. By utilizing the cooperation between the inclined surfaces, when installing the locking block 4 and the mold core 2, when the inclined surface of one end of the locking block 4 contacts the inclined surface of one end of the limiting rod 8, the locking block 4 continues to slide and install. Thus, by utilizing the action of the inclined surfaces, the limiting rod 8 and the slide plate 7 can be lifted up and the spring 6 can be squeezed. When the locking block 4 is installed in the designated position, under the elastic force of the spring 6, the slide plate 7 and the limiting rod 8 return to their original positions. At this time, the limiting rod 8 enters the interior of the limiting groove 9, thus enabling the installation operation to be completed quickly.

[0032] Working principle:

[0033] When in use, first install the L-shaped plate 1 in the designated position through the four fixing holes 10 on its top, then slide the card block 4 at one end of the mold core 2 to be used into the slot 3, and slide the slide bar 14 on the outside of the card block 4 into the slide groove 13 on the outside of the limit box 5.

[0034] When the inclined surface of one end of the locking block 4 contacts the inclined surface of one end of the limiting rod 8, continue to slide the locking block 4. By using the action of the inclined surface, the limiting rod 8 and the slide plate 7 can be lifted and the spring 6 can be squeezed. When the locking block 4 is installed in the designated position, the slide plate 7 and the limiting rod 8 return to their original positions under the elastic force of the spring 6. At this time, the limiting rod 8 enters the interior of the limiting groove 9, so that the installation operation can be completed quickly.

[0035] After installation, the car square tube beam to be drilled is placed on the outside of the mold core 2. Then, the drilling operation is carried out by the drill rod on the external drilling device in conjunction with the positioning hole 12 on the outside of the mold core 2. The mold core 2 can stably support and position the car square tube beam during the drilling process, thereby avoiding deformation around the hole diameter during the drilling process, which is beneficial to practical application and operation.

[0036] When it is necessary to replace the mold core 2 with a different model, manually move the slide plate 7 to move it inside the limit box 5 and squeeze the spring 6. At the same time, the limit rod 8 will disengage from the limit groove 9. Then the mold core 2 and the locking block 4 can be slid to disassemble them. Then, the above operation can be performed to reinstall the new mold core 2. It is convenient and quick.

[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.
