Description

Technical Field

[0001] This utility model relates to the field of chip clamping fixture technology, and in particular to a chip cleaning fixture. Background Technology

[0002] During chip cleaning, the chip is usually clamped in a corresponding fixture, and then the device is placed into the cleaning equipment for cleaning.

[0003] For example, the patent with publication number CN220172096U discloses a chip cleaning fixture that uses two parallel rods to clamp the chip and uses a groove at the bottom to limit the chip's position. However, the chip itself is relatively fragile and can easily be damaged during clamping due to uneven clamping surfaces of the fixture. Utility Model Content

[0004] To solve or partially solve the problems existing in related technologies, this utility model provides a chip cleaning fixture, which aims to solve the technical problem that existing fixtures easily damage chips when holding them.

[0005] The aforementioned chip cleaning fixture includes a fixed plate, a fixed limiting block, a movable limiting block, a lateral limiting block, and a load-bearing block.

[0006] The plate is provided with two sets of lateral limiting blocks arranged opposite to each other. The cavity between the two sets of lateral limiting blocks is a chip clamping station. The chip clamping station is provided with a load-bearing block for supporting the chip.

[0007] A fixed limiting block is provided on the left side of the chip clamping station, and a sliding groove is provided on the right side of the chip clamping station, in which a movable limiting block is slidably installed.

[0008] The movable limiting block is provided with a limiting inclined surface, which makes point contact or line contact with the upper side edge of the chip located in the chip clamping station.

[0009] In some embodiments, the angle between the projection of the limiting inclined plane onto the vertical plane and the horizontal plane is 30 to 55 degrees.

[0010] The height of the upper side of the chip is higher than the height of the lowest point of the limiting slope, but lower than the height of the highest point of the limiting slope.

[0011] In some solutions, the top of the side of the movable limiting block near the chip clamping station is provided with a limiting part extending toward the chip clamping station, and the bottom surface of the limiting part is inclined to form the limiting slope.

[0012] In some designs, two limiting parts are provided, symmetrically distributed about the centerline of the chip clamping station.

[0013] In some designs, the movable limiting block is provided with a waist-shaped limiting hole, and the locking screw passes through the waist-shaped limiting hole and is screwed into the fixed plate thread.

[0014] When one side of the chip located in the chip clamping station abuts against the fixed limiting block, the locking screw abuts against the right inner side of the waist-shaped limiting hole.

[0015] In some embodiments, the fixed limiting block includes a connecting part, an abutting part, and a guiding part distributed sequentially from bottom to top;

[0016] The top surface of the connecting part, the bottom surface and the top surface of the guide part are inclined, and the diameter of the abutting part is smaller than the diameter of the connecting part and smaller than the diameter of the guide part.

[0017] In some embodiments, each set of the lateral limiting blocks comprises two cylindrical lateral limiting blocks, the tops of which are tapered.

[0018] In some embodiments, the fixed plate has four grooves arranged in a cross shape, and the drainage groove extends radially from the outer end of the groove through the outer circumference of the fixed plate.

[0019] The technical solution provided by this utility model can include the following beneficial effects:

[0020] This application uses lateral limiting blocks to limit and support the chip on both the front and rear sides; fixed limiting blocks and movable limiting blocks limit the left and right sides of the chip respectively, and make point or line contact with the chip, reducing the contact area with the chip, making it less likely to damage the chip, and improving safety during the chip clamping process.

[0021] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit the present invention. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited to the content described.

[0030] Please see Figures 1 to 4 This application provides a chip cleaning fixture, including a fixed plate 1, a fixed limiting block 3, a movable limiting block 4, a lateral limiting block 5, and a load-bearing block 6.

[0031] The fixed plate 1 is provided with two sets of lateral limiting blocks 5 arranged opposite to each other. Each set of lateral limiting blocks 5 includes two square lateral limiting blocks 5. The cavity between the two sets of lateral limiting blocks 5 is a chip clamping station 7. The chip clamping station 7 is provided with a load-bearing block 6 for supporting the chip. At the same time, the chip is supported by the load-bearing block 6. Compared with placing the chip directly on the fixed plate 1, the contact area between the chip and the plate is reduced, and the chip is more convenient to move. Furthermore, there is a certain gap between the chip and the fixed plate 1 to facilitate the outflow of water during chip cleaning.

[0032] The chip clamping station 7 has a fixed limiting block 3 on the left side for limiting the left side of the chip, and a sliding groove 11 on the right side of the chip clamping station 7. A movable limiting block 4 is slidably installed in the sliding groove 11 for limiting the right side of the chip.

[0033] When the chip needs to be cleaned, the chip is placed in the chip clamping station 7, and then the movable limit block 4 is pushed to move along the slide groove 11, so that the movable limit block 4 moves closer to the fixed limit block 3, thereby firmly clamping the chip in the chip clamping station 7. Then the entire fixture is installed into the chip cleaning device for cleaning, which helps to improve the chip cleaning efficiency.

[0034] In this embodiment, the movable limiting block 4 is generally square. The top of the movable limiting block 4 near the chip clamping station 7 has a limiting part 42 extending towards the chip clamping station 7. The bottom surface of the limiting part 42 is inclined to form the limiting slope 41. When clamping the chip, the limiting slope 41 makes point contact or line contact with the upper side edge of the chip located in the chip clamping station 7, thereby pressing the chip in the chip clamping station 7 through the limiting slope 41. At the same time, it avoids the problem of excessive pressure on part of the chip due to insufficient chip edge flatness, which would damage the chip. It also avoids the problem of excessive pressure on part of the chip due to insufficient flatness of the fixed limiting block 3 edge, which would damage the chip. This effectively improves the safety of chip clamping.

[0035] Preferably, the angle between the projection of the limiting inclined surface 41 on the vertical plane and the horizontal plane is 30 degrees to 55 degrees; such as any angle between 30 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees and 30 degrees to 55 degrees; the height of the upper side of the chip is higher than the height of the lowest point of the limiting inclined surface 41 and lower than the height of the highest point of the limiting inclined surface 41.

[0036] In this embodiment, two limiting parts 42 are provided, symmetrically distributed about the center line of the chip clamping station 7, to limit the chip at multiple points and further improve the stability of chip clamping.

[0037] In this embodiment, the movable limiting block 4 is provided with a waist-shaped limiting hole 43. After the locking screw 8 passes through the waist-shaped limiting hole 43, it is threadedly connected to the fixed plate 1. When the movable limiting block 4 is pushed to the designated position (when the movable limiting block 4 abuts against the chip), the locking screw 8 is tightened to fix the position of the movable limiting block 4, so as to avoid the chip falling off due to the movement of the movable limiting block 4 during the cleaning process, and to ensure the stability of chip clamping.

[0038] Preferably, when one side of the chip located in the chip clamping station 7 abuts against the fixed limiting block 3, the locking screw 8 abuts against the right inner side of the waist-shaped limiting hole 43. In this way, the cooperation between the waist-shaped limiting hole 43 and the locking screw 8 realizes the limitation of the movable limiting block 4's movable distance, avoiding the technical problem of chip damage caused by the movable limiting block 4 moving too far, and ensuring the safety of the chip during the chip clamping process.

[0039] In this embodiment, the fixed limiting block 3 is generally cylindrical and includes a connecting part 31, an abutting part 32, and a guiding part 33 distributed sequentially from bottom to top. The connecting part 31 is fixedly connected to the fixed plate 1. The top surface of the connecting part 31, the bottom surface and the top surface of the guiding part 33 are inclined. The diameter of the abutting part 32 is smaller than the diameter of the connecting part 31 and smaller than the diameter of the guiding part 33. When clamping the chip, the abutting part 32 contacts the side edge of the chip to limit the chip. The inclined arrangement of the top surface of the connecting part 31, the bottom surface and the top surface of the guiding part 33 allows the upper and lower sides of the chip to be fully exposed, ensuring that the chip can be cleaned. At the same time, it can limit the chip's upper and lower sides to ensure that the chip is firmly clamped.

[0040] In this embodiment, the top of the side limiting block 5 is conical, thereby guiding the process of placing the chip into the chip clamping station 7 to ensure that the chip can be placed smoothly and correctly into the chip clamping station 7.

[0041] In this embodiment, four grooves 11 are distributed in a cross shape on the fixed plate 1. The drainage groove 2 extends from the outer end of the groove 11 and penetrates the outer circumference of the fixed plate 1 radially. In this way, when cleaning the chip, the cleaning agent can flow out of the fixture from the drainage groove 2, effectively avoiding the technical problem of cleaning solution accumulating on the fixture during cleaning.

[0042] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
