Technical Field

[0001] The present invention relates to an automatic pressing fixture, and more particularly to an automatic pressing fixture for CNC high-gloss machining of a computer case. Background Art

[0002] Traditional CNC high-gloss fixtures require manual picking and placing of the cover plate. The cover plate is unevenly pressed, resulting in problems such as chatter marks, over-milling, pressing damage, and low efficiency after processing. Moreover, two workstations are required to complete the processing. There is an urgent need for a new solution to improve the CNC high-gloss fixture to increase the yield and efficiency.

[0003] Combined with the company's situation, an automatic pressing fixture for CNC high-gloss machining of a computer case with simple operation, relatively low technical requirements, and stable and reliable performance is developed. Summary of the Invention

[0004] The main object of the present disclosure is to provide an automatic pressing fixture for CNC high-gloss machining of a computer case, which adopts a ball head flexible connection automatic leveling and pressing mechanism to replace the limitations of the rigid pressing of the lever cylinder, thereby realizing automatic and uniform pressing of the cover plate on the product, improving the processing efficiency and yield, and being convenient to operate, so as to effectively solve the problems raised by the inventor in the above background art.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] An automatic pressing fixture for CNC high-gloss machining of a computer case, comprising a product main body and a bottom mold. A cavity is provided at the top of the bottom mold, and the product main body is placed in the cavity. A gas storage plate is fixedly installed at the bottom of the bottom mold, and a plurality of mold feet are fixedly installed at the bottom of the gas storage plate. A three-way joint is fixedly installed at the front side of the gas storage plate. One end of the three-way joint is blocked, and a hand slide valve is fixedly installed at the other end. A bracket is fixedly connected to the rear side of the bottom mold, and a cylinder main body is fixedly installed at the lower end of the bracket. The output end of the cylinder main body passes through a through hole on the bracket and is connected to a cylinder connection head main body. A lever ball head pressing block is movably installed on the cylinder connection head main body through a cylinder connection head positioning pin. A cover plate is installed on the lever ball head pressing block, and the cover plate faces the product main body.

[0007] Preferably, two first mold closing positioning pins are fixedly installed in the cavity, and the first mold closing positioning pins penetrate through the product main body.

[0008] Preferably, four second mold closing positioning pins are fixedly installed in the cavity, and the second mold closing positioning pins penetrate through the product main body.

[0009] Preferably, an I-shaped urethane rubber is fixedly connected to the edge of the bottom of the cover plate, and a profiling urethane rubber is fixedly connected to the edge of the top of the bottom mold.

[0010] Preferably, a support seat is fixedly mounted on the bracket, a rotation positioning pin is mounted on the lever ball head pressure block, a connecting hinge is movably mounted on the support seat, and the connecting hinge is movably mounted on the rotation positioning pin.

[0011] Preferably, a support block is fixedly mounted on the cover plate, and a lever ball head pressure block is arranged on the support block, and equal-height screws are threadedly mounted on the support block, and the equal-height screws are screwed into the lever ball head pressure block.

[0012] Preferably, the support block is fixedly mounted on the cover plate by support block positioning screws.

[0013] Preferably, a cylinder speed regulating joint is fixedly mounted on the cylinder body.

[0014] In view of this, compared with the prior art, the beneficial effects of the present invention are:

[0015] (i) In this application, the product is placed on the CNC high-gloss processing automatic clamping fixture, and the switch is turned on. The cylinder body drives the cover plate to rotate and clamp the product body. There is no need to manually move the cover plate, and the cover plate can be automatically clamped to process the product.

[0016] (ii) In the present application, the traditional lever cylinder is a cover plate and a cylinder that are rigidly fixed directly, which can only press down a local area and is not suitable for large CNC highlight areas. This computer shell CNC highlight processing automatic clamping fixture adopts a ball head flexible connection cover plate to automatically level and clamp the product. One person can look after multiple CNC equipment to improve the yield and efficiency. The I-shaped glue is assembled on the fixture cover plate, and the bottom mold of the fixture is filled with contour glue. When the cover plate is pressed, it acts as a buffer to prevent risks such as damage to the product appearance, and simultaneously makes the product pressed tighter, without the risk of vibration and over-milling. The I-shaped glue can be replaced after it is worn, and the production efficiency is high.

[0017] (III) In this application, the product periphery and TP areas are processed. Conventional fixtures require two workstations to complete the processing of the highlight area. Now, a ball head flexible connection cover plate and I-shaped high-strength glue are used. The advantage of the ball head flexible connection cover plate is that it can be designed to be thinner, which is convenient for processing area avoidance processing. It can also automatically press all areas, and one workstation can complete CNC highlight processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1-7 , the present invention provides the following embodiments:

[0029] An automatic clamping fixture for CNC high-gloss machining of a computer case, including a product main body 1 and a bottom die 2. A cavity is formed at the top of the bottom die 2, and the product main body 1 is placed in the cavity. A gas storage plate 4 is fixedly installed at the bottom of the bottom die 2, and a number of die feet 5 are fixedly installed at the bottom of the gas storage plate 4. A three-way joint 6 is fixedly installed on the front side of the gas storage plate 4. One end of the three-way joint 6 is blocked, and a hand slide valve 7 is fixedly installed at the other end. A bracket is fixedly connected to the rear side of the bottom die 2, and a cylinder main body 20 is fixedly installed at the lower end of the bracket. The cylinder main body 20 is equipped with a switch. The output end of the cylinder main body 20 penetrates through the through hole on the bracket and is connected to a cylinder connection head main body 18. A lever ball head pressing block 14 is movably installed on the cylinder connection head main body 18 through a cylinder connection head positioning pin 19. A cover plate 11 is installed on the lever ball head pressing block 14, and the cover plate 11 faces the product main body 1.

[0030] Specifically, two first mold closing positioning pins 8 are fixedly installed in the cavity, and the first mold closing positioning pins 8 penetrate through the product main body 1. Four second mold closing positioning pins 9 are fixedly installed in the cavity, and the second mold closing positioning pins 9 penetrate through the product main body 1.

[0031] Specifically, an I-shaped urethane rubber 10 is fixedly connected to the edge of the bottom of the cover plate 11, and a profiling urethane rubber 3 is fixedly connected to the edge of the top of the bottom die 2.

[0032] Specifically, a support seat 15 is fixedly installed on the bracket. A rotating positioning pin 17 is installed on the lever ball head pressing block 14. A connecting hinge 16 is movably installed on the support seat 15, and the connecting hinge 16 is movably installed on the rotating positioning pin 17. A support block 13 is fixedly installed on the cover plate 11, and the lever ball head pressing block 14 is arranged on the support block 13. A height equalizing screw 12 is threadedly installed on the support block 13, and the height equalizing screw 12 is screwed into the lever ball head pressing block 14. The support block 13 is fixedly installed on the cover plate 11 through a support block positioning screw 21. The above structure constitutes an automatic leveling and clamping mechanism.

[0033] Specifically, a cylinder speed regulating joint 22 is fixedly installed on the cylinder main body 20.

[0034] The specific implementation mode of this embodiment is as follows: The product is placed on the automatic clamping fixture for CNC high-gloss machining. The switch is started, and the cylinder main body 20 drives the cover plate 11 to rotate and clamp the product main body 1. There is no need to manually carry the cover plate 11, realizing the automatic clamping of the cover plate 11 for processing the product;

[0035] In the traditional method, the lever cylinder is directly rigidly fixed between the cover plate 11 and the cylinder, and can only press a local area, which is not suitable for the large surface area of CNC high-gloss. This automatic clamping fixture for CNC high-gloss machining of a computer case uses a ball head to flexibly connect the cover plate to automatically level and clamp the product. One person can monitor multiple CNC devices, improving the yield and efficiency;

[0036] The I-beam urethane rubber 10 is assembled on the fixture cover plate 11, and the profiling urethane rubber 3 is filled in the fixture bottom mold 2. When the cover plate 11 is pressed, it plays a buffering role to prevent risks such as damage to the appearance of the product. At the same time, it makes the product pressed more tightly, and there is no risk of vibration cutting or milling. After the I-beam urethane rubber 10 is worn, it can be replaced with a new one, and the production efficiency is high;

[0037] The periphery of the product and two areas of the TP are processed. Conventional fixtures require two workstations to complete the processing of the high-gloss area. Now, the ball head is used to flexibly connect the cover plate 11 and the I-beam urethane rubber 10. The advantage of the ball head flexible connection cover plate 11 is that it can be designed thinner to facilitate avoiding the processing area, and it can also automatically press all areas, and one workstation can complete the CNC high-gloss processing.

[0038] In summary, the fixture adopts a ball head flexible connection automatic leveling and pressing mechanism to replace the limitations of the rigid pressing of the lever cylinder, so as to realize the automatic and uniform pressing of the cover plate 11 on the product, improve the processing efficiency, improve the yield, and is convenient to operate.
