Description

Technical Field

[0001] The utility model relates to the technical field of flat plate middle frame processing, in particular to a fixture used for clamping a hardware body processed by a machining center. Background Art

[0002] The tablet midframe usually refers to the metal or plastic frame part of a tablet computer. It plays an important role in the design and construction of a tablet computer. The midframe provides the necessary physical support for the tablet, ensuring its structural stability and durability.

[0003] At present, the antenna of a tablet computer is usually integrated on the inner side of the middle frame. When the middle frame is processed, a groove needs to be made on the inner side of the middle frame to facilitate the subsequent installation of the antenna. However, when the groove is made on the inner side of the middle frame, the clamping and positioning speed of the middle frame is slow, which makes it difficult to improve the efficiency during processing. Therefore, a fixture for clamping a hardware body based on processing in a machining center is needed to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a fixture for clamping a hardware body based on machining center processing, which has the advantage of increasing the clamping and positioning speed of the middle frame to be processed, and solves the problem that the processing efficiency is difficult to improve due to the slow clamping and positioning speed of the middle frame.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixture for clamping a hardware body processed by a machining center, comprising a bottom plate, a limit plate is fixedly installed on the upper surface of the bottom plate, a middle frame is movably placed on the upper surface of the bottom plate outside the limit plate, and also comprises a bottom plate and a slide groove;

[0006] A clamping frame is movably installed at the rear end of the upper surface of the bottom plate;

[0007] The inner side of the clamping frame is in contact with the outer wall of the rear end of the middle frame member but is not fixedly connected;

[0008] The chutes are opened on both sides of the front end of the bottom plate;

[0009] A slider is slidably installed in the slide groove, and a pressure block is fixedly installed on the top of the slider through a connecting frame;

[0010] The lower end surface of the pressing block contacts the upper end surface of the middle frame member but is not fixedly connected.

[0011] When using a fixture for clamping a hardware body based on machining center processing in the technical solution, pull the pull rod to move the clamping frame upward along the slide rod, and place the middle frame on the upper surface of the bottom plate through the limit plate, and make the outer side of the limit plate contact with the inner side of the middle frame but not fixedly connected, which helps to preliminarily locate the position of the middle frame, and by loosening the pull rod, the clamping frame clamps the rear end of the middle frame under the action of the connecting spring, and at the same time, push the connecting frame and move the slider along the slide groove direction, so as to clamp the upper end face of the middle frame through the pressure block, thereby realizing the clamping and positioning of the middle frame, and after confirming that the middle frame is stably clamped on the fixture and the position is accurate, perform machining center processing, and during the entire machining process, the fixture should be able to provide sufficient support and positioning accuracy to ensure machining accuracy and stability.

[0012] Preferably, sliding rods are fixedly installed on both sides of the rear end of the upper surface of the bottom plate, and first connecting rods are fixedly installed on both sides of the rear end of the bottom plate.

[0013] The slide bars are installed on both sides of the rear end of the upper surface of the bottom plate, which helps to provide additional support and enhance the stability of the clamping frame. The fixed installation of the first connecting rod provides an additional stable support point for the installation of the clamping frame, enhancing the rigidity and durability of the overall structure.

[0014] Preferably, the thickness of the limiting plate matches the thickness of the middle frame, and the outer side of the limiting plate contacts the inner side of the middle frame but is not fixedly connected.

[0015] The thickness of the limit plate matches that of the middle frame, ensuring accurate positioning of the middle frame during processing.

[0016] Preferably, the front end of the clamping frame is flush with the inner side of the middle frame, a pull rod is fixedly installed in the middle of the top of the clamping frame, holes are opened on the clamping frames on both sides of the pull rod and sleeves are embedded and installed, the top of the sliding rod passes through the sleeve, and second connecting rods are fixedly installed on both sides of the clamping frame.

[0017] The front end of the clamping frame is flush with the inner side of the middle frame to ensure stable clamping and positioning of the middle frame. The design of the pull rod and the slide rod allows the clamping frame to be fine-tuned in the vertical direction to improve the flexibility and accuracy of clamping.

[0018] Preferably, a connecting spring is elastically mounted on the second connecting rod, the bottom end of the connecting spring is elastically connected to the first connecting rod, and the connecting spring adopts a tension spring structure design.

[0019] The connecting spring adopts a tensile spring structure design, which can make the clamping frame as close to the bottom plate as possible when no force is applied, and always provide appropriate clamping force. The elastic design of the connecting spring allows a certain elastic space during the clamping process, reducing damage to the middle frame while providing stable support. The elastic connection between the connecting spring and the first connecting rod provides fine control capabilities, ensuring the stability and precision of the middle frame during processing.

[0021] Both the pressure block and the clamping frame are made of hard rubber, which is a relatively soft material that can reduce damage to the middle frame during processing. The design of the hard rubber material helps to provide uniform pressure distribution when the pressure block and the clamping frame contact the middle frame, avoiding excessive local stress. The hard rubber material reduces the frequency of wear and replacement, and improves the overall economy and reliability.

This design reduces the time of fixing and adjustment and speeds up the clamping process. The limit plate is fixedly installed on the upper surface of the bottom plate, and the outer side is in contact with the inner side of the middle frame member but not fixedly connected. This design provides preliminary positioning and support, ensuring that the middle frame will not shift during the clamping process, reducing the need for repositioning and thus improving efficiency.

This design enables the clamping frame 5 to flexibly adjust its position , reducing the adjustment time and complexity, and improving the clamping speed. The slide groove 2 is opened on both sides of the front end of the bottom plate 1, and a slider 14 is slidably installed in the slide groove 2. This design allows the slider 14 to slide freely in the slide groove 2, so as to quickly adjust the position of the pressure block 13, and realize the rapid positioning and clamping of the middle frame 4. The lower end surface of the pressure block 13 contacts the upper end surface of the middle frame 4 but is not fixedly connected. This design reduces the time for fixing and adjustment and speeds up the clamping process. The limit plate 7 is fixedly installed on the upper surface of the bottom plate 1, and the outer side contacts the inner side of the middle frame 4 but is not fixedly connected. This design provides preliminary positioning and support, ensuring that the middle frame 4 will not shift during the clamping process, reducing the need for repositioning, thereby improving efficiency. The inner side of the clamping frame 5 contacts the outer wall of the rear end of the middle frame 4, and cooperates with the lower end face of the pressure block 13 to form a stable clamping structure. This coordination effect not only ensures the stable positioning of the middle frame 4, but also reduces the re-clamping caused by improper adjustment, thereby improving the processing efficiency. The design of the entire fixture takes into account the convenience and efficiency of operation. By optimizing the layout and functions of each component, the operation steps and time are reduced, thereby achieving the effect of improving the clamping and positioning speed of the middle frame to be processed.

[0039] The front end of the clamping frame 5 is flush with the inner side of the middle frame 4, ensuring stable clamping and positioning of the middle frame 4. The design of the pull rod 11 and the slide rod 8 allows the clamping frame 5 to be fine-tuned in the vertical direction, improving the flexibility and accuracy of clamping. The matching design of the sleeve 12 and the slide rod 8 makes the clamping frame 5 more stable when sliding.

[0040] Furthermore, a connecting spring 6 is elastically mounted on the second connecting rod 10 , and the bottom end of the connecting spring 6 is elastically connected to the first connecting rod 9 . The connecting spring 6 is designed with a tension spring structure.

[0041] The connecting spring 6 adopts a tension spring structure design, which can make the clamping frame 5 as close to the base plate 1 as possible when no force is applied, and always provide appropriate clamping force. The elastic design of the connecting spring 6 allows a certain elastic space during the clamping process, reducing damage to the middle frame 4 while providing stable support. The elastic connection between the connecting spring 6 and the first connecting rod 9 provides fine control capabilities, ensuring the stability and precision of the middle frame 4 during processing.

[0043] The pressing block 13 and the clamping frame 5 are both made of hard rubber, which is a relatively soft material that can reduce damage to the middle frame 4 during processing. The design of the hard rubber material helps to provide uniform pressure distribution when the pressing block 13 and the clamping frame 5 are in contact with the middle frame 4, avoiding excessive local stress. The hard rubber material reduces the frequency of wear and replacement, and improves the overall economy and reliability.
