Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a tooling for removing the core of a vehicle headlight sealing gasket. Background Technology
[0002] Automotive parts manufacturing refers to the production process of processing raw materials such as metals, plastics, rubber, and electronic components into various automotive parts through various technologies and ensuring that they meet the assembly requirements of the complete vehicle. When the production scale of headlight sealing gaskets is large (such as automotive parts mass production lines), the manual removal of the core material has obvious limitations. Manually removing the core material one by one is difficult to match the pace of automated production lines. Large-scale production requires a large number of workers, which increases enterprise costs and causes efficiency fluctuations due to personnel fatigue.
[0003] A search revealed Chinese patent publication number CN208880059U, which discloses a tooling for removing automotive headlight sealing gasket cores. The tooling includes a base plate, a middle plate, an upper plate, and four uprights. The base plate has multiple vertical push rods spaced apart at intervals in its center. The middle plate, located above the base plate, has multiple sealing gasket storage holes spaced apart at intervals in its center, the number of which corresponds to the number of push rods. The upper plate, located above the middle plate, also has multiple core storage holes spaced apart at intervals in its center, the number of which corresponds to the number of push rods. A support is provided between the upper and middle plates. The four uprights are located at the four corners of the base plate, vertically aligned, with their tops passing through the middle and upper plates sequentially. A first spring is fitted onto each upright, and the middle plate rests on the first spring. This invention improves removal and packaging efficiency, significantly reducing the labor intensity of workers.
[0004] While the above solutions improve removal and packaging efficiency, some existing gasket core removal fixtures are difficult to disassemble. When dealing with gasket cores of different sizes and shapes, the difficulty in disassembling the fixture makes it hard to replace the corresponding clamps, cutters, or positioning components in a timely manner. This results in the fixture being limited to removing only one type of gasket core. The inflexible replacement of parts makes it difficult to use in multiple scenarios, requiring the purchase of multiple sets of dedicated fixtures, thus increasing costs. Therefore, a new automotive headlight gasket core removal fixture is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a tooling for removing the core of a vehicle headlight sealing gasket, which solves the problem that some existing tools for removing the core of a sealing gasket are difficult to disassemble.
[0006] To achieve the above objectives, this utility model provides a tooling for removing automotive lamp sealing gasket cores, including a base plate. Multiple top rods are fixedly connected to the top of the base plate, and columns are fixedly connected to the four corners of the top of the base plate. A spring is fitted onto the bottom outer end of each column. A middle plate is slidably connected to the outer surface of the columns, and a spring is fitted onto the top outer end of each column. An upper plate is fixedly connected to the top of each spring. A connecting plate is detachably connected to the interior of the upper plate, and a cylindrical body is fixedly connected to the bottom of the connecting plate. A sealing gasket storage hole is detachably connected to the interior of the middle plate. Multiple positioning components are installed at the bottom of the upper plate. Two disassembly components are installed on the left and right sides of the interior of the upper plate, and two more disassembly components are installed on the left and right sides of the interior of the middle plate.
[0007] The disassembly assembly includes a pull rod, which is slidably connected to the inner wall of the upper plate. One end of the pull rod is fixedly connected to a sliding frame. The sliding frame has square openings on both the front and rear sides. A spring is fixedly connected inside the square opening. A rotating plate is rotatably connected to the inner wall of the square opening. Connecting blocks are fixedly connected to both the left and right sides of the connecting plate.
[0008] The positioning component includes a positioning rod, the top of which is fixedly connected to the bottom of the upper plate, a limiting plate is sleeved on the outside of the positioning rod, and a tension spring is fixedly connected to the bottom of the positioning rod.
[0009] The external parts of the plurality of positioning rods are slidably connected to the inside of the middle layer plate, and the top of the tension spring is in contact with the bottom of the middle layer plate.
[0010] The upper plate has through holes on both the left and right sides, and the sliding frame is slidably connected to the inner wall of the through holes.
[0011] The connecting block has square openings at both the front and back, and the outer side of the rotating plate engages with the inner wall of the connecting block.
[0012] The pull rod is externally fixedly connected to a sliding plate, and a spring is sleeved on the outside of the pull rod.
[0013] The outside of the top rod is in contact with the inside of the sealing gasket receiving hole.
[0014] Two of the tie rods are externally slidably connected to the left and right sides of the interior of the middle layer plate, and two of the sliding plates are externally slidably connected to the interior of the upper layer plate.
[0015] 1. In this utility model, when it is necessary to disassemble the connecting plate, the operator pulls the pull rod outward, causing the sliding frame to slide along the through hole of the upper plate. During this process, the pull rod simultaneously drives the sliding plate to move, causing the spring four sleeved on the pull rod to be compressed and contracted. When the rotating plate on the sliding frame moves, it is squeezed inward due to the obstruction of the square opening in the connecting block, compressing the spring three in the square opening and continuously pulling the pull rod, thus realizing the disassembly of the sealing gasket core removal fixture, which can then process sealing gaskets of different sizes, saving processing costs.
[0016] 2. In this utility model, during operation, pressing down on the upper plate compresses the springs outside the column, while the positioning rod in the positioning assembly is inserted into the corresponding hole of the headlight. The limiting plate cooperates with the middle plate to achieve guiding positioning during processing, thereby reducing vibration and offset during removal, avoiding abnormal wear of tooling parts due to uneven force, and extending service life.

Detailed Implementation
[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0024] Please see Figures 1-3 This utility model provides an embodiment of a tooling for removing a vehicle headlight sealing gasket core, comprising a base plate 1, with multiple push rods 2 fixedly connected to the top of the base plate 1, and columns 4 fixedly connected to the four corners of the top of the base plate 1. A spring 5 is fitted onto the outer bottom end of each column 4. When the upper plate 7 is pressed downwards by an external force, the spring 5 is compressed and accumulates elastic potential energy. When the external force is removed, the spring 5 releases its elastic potential energy, causing the middle plate 3 to reset, allowing the tooling to return to its initial state for the next operation. The middle plate 3 is slidably connected to the outer sides of the multiple columns 4, and a spring 6 is fitted onto the outer top end of each column 4. The top of spring 26 is fixedly connected to the upper plate 7. The column 4 also provides a guide for the vertical sliding of the middle plate 3 and the upper plate 7. The spring 1 5 and spring 2 6 sleeved on the outside provide elastic support and buffer during the movement of the middle plate 3 and the upper plate 7, respectively, to ensure the stability and reliability of each component during the movement. The upper plate 7 is detachably connected to the inside of the connecting plate 8. The bottom of the connecting plate 8 is fixedly connected to the cylindrical body 9. The main function of the cylindrical body 9 is to cooperate with the headlight sealing gasket core. During the operation of the tooling, the headlight sealing gasket core is removed by applying force to it. The shape and size design of the cylindrical body 9 can ensure a tight fit with the sealing gasket core, improving the efficiency and accuracy of the removal work. The middle plate 3 has a detachable sealing gasket storage hole 10 inside. Multiple positioning components 11 are installed at the bottom of the upper plate 7. Two of the disassembly components 12 are installed on the left and right sides inside the upper plate 7. Two other disassembly components 12 are installed on the left and right sides inside the middle plate 3.
[0025] Reference Figures 1 to 3The disassembly assembly 12 includes a pull rod 120, which is slidably connected to the inner wall of the upper plate 7. One end of the pull rod 120 is fixedly connected to a sliding frame 121. The sliding frame 121 has square openings 122 on both the front and rear sides. A spring 123 is fixedly connected inside the square opening 122. A rotating plate 124 is rotatably connected to the inner wall of the square opening 122. During the sliding of the sliding frame 121, the inner wall of the square opening 122 interacts with the connecting block 125, causing the rotating plate 124 to rotate. When obstructed, the spring 123 is compressed inward, separating the rotating plate 124 from the connecting block 125, thus completing the disassembly of the connecting plate 8. Connecting blocks 125 are fixedly connected to both the left and right sides of the connecting plate 8. Through holes 126 are provided on both the left and right sides of the interior of the upper plate 7. The sliding frame 121 is slidably connected to the inner wall of the through hole 126. The size and shape design of the through hole 126 ensures smooth sliding of the sliding frame 121 within it and also guides the movement of the sliding frame 121. To ensure accurate and stable disassembly of component 12, the connecting block 125 has square openings at both the front and rear. The outer side of the rotating plate 124 engages with the inner wall of the connecting block 125. When the pull rod 120 is pulled, the rotating plate 124, blocked by the connecting block 125, compresses the spring 123 inward. After overcoming the block, it pops out under the elastic force of the spring 123 and separates from the connecting block 125, completing the disassembly of the connecting plate 8. A sliding plate 127 is fixedly connected to the outside of the pull rod 120. Spring 128 is sleeved on the outside of 120. When the operator releases the pull rod 120, spring 128 releases elastic potential energy and pushes the pull rod 120 to reset, so that the disassembly assembly 12 returns to its initial state, which facilitates the next disassembly operation and plays the role of reset and buffer. The outside of the top rod 2 is in contact with the inside of the sealing gasket storage hole 10. The outside of the two pull rods 120 are slidably connected to the left and right sides of the inside of the middle plate 3, and the outside of the two sliding plates 127 are slidably connected to the inside of the upper plate 7.
[0026] Reference Figure 1 and Figure 4The positioning assembly 11 includes a positioning rod 110, the top of which is fixedly connected to the bottom of the upper plate 7. A limiting plate 111 is sleeved on the outside of the positioning rod 110. When the positioning rod 110 is inserted into the headlight hole, the limiting plate 111 contacts the middle plate 3 to prevent the positioning rod 110 from being over-inserted and damaging the headlight. This also ensures that the positioning rod 110 is positioned correctly to locate the headlight, guaranteeing the accuracy and reliability of the positioning. A tension spring 112 is fixedly connected to the bottom of the positioning rod 110. Multiple... The positioning rod 110 is externally slidably connected to the inside of the middle layer plate 3. The positioning rod 110 is inserted into the corresponding hole of the headlight to achieve precise positioning of the headlight. The limiting plate 111 cooperates with the middle layer plate 3 to prevent the positioning rod 110 from being over-inserted and to ensure the accuracy of positioning. The tension spring 112 provides pre-tightening force so that the positioning rod 110 always maintains close contact with the headlight hole, ensuring that the headlight will not be displaced during the tooling operation, and ensuring the stability and reliability of operation. The top of the tension spring 112 is in contact with the bottom of the middle layer plate 3.
[0027] Working principle: The headlight to be processed is placed on the base plate 1 and initially supported by the top rod 2. During operation, the upper plate 7 is pressed down, the spring 6 on the outside of the column 4 is compressed, and at the same time, the positioning rod 110 in the positioning assembly 11 is inserted into the corresponding hole of the headlight. The limiting plate 111 cooperates with the middle plate 3 to achieve precise positioning of the headlight. The tension spring 112 provides pre-tightening force to ensure stable positioning. During the pressing down of the upper plate 7, the middle plate 3 moves down synchronously under the action of the spring 5, so that the sealing gasket storage hole 10 is aligned with the headlight sealing gasket core, and the pressing and fixing are completed.
[0028] When it is necessary to disassemble the connecting plate 8, the operator pulls the pull rod 120 outward, causing the sliding frame 121 to slide along the through hole 126 of the upper plate 7. During this process, the pull rod 120 simultaneously drives the sliding plate 127 to move, causing the spring 128 sleeved on the pull rod 120 to be compressed and contracted. When the rotating plate 124 on the sliding frame 121 moves, it is squeezed inward due to the obstruction of the square opening in the connecting block 125, compressing the spring 123 in the square opening 122. By continuously pulling the pull rod 120, the rotating plate 124 passes the obstruction of the square opening in the connecting block 125 and pops out under the elastic force of the spring 123, separating from the connecting block 125. This achieves the disengagement of the connecting plate 8 from the disassembly assembly 12, completing the disassembly of the components of the sealing gasket core removal tooling.
[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
