Although this kind of fixture can select appropriate mounting holes and processing through holes to set the telescopic positioning member and the clamping member according to the structure of the mobile phone middle frame. However, during the operation of this type of clamp, the worker needs to directly put his hand into the mold plate to take and place the mobile phone middle frame. This operation method has certain safety hazards. In a fast production environment, especially under high-pressure working conditions, workers are prone to misoperation due to fatigue or lack of concentration. If the clamp is suddenly started during operation or the worker's hand is not completely out of the clamp range, it is very easy to cause a pinching accident. Therefore, improvements are needed. Summary of the invention

[0004] In order to solve the above problems, the utility model proposes a highly stable mobile phone middle frame clamp to more accurately solve the problem of the clamp being suddenly started or the staff's hands not completely withdrawing from the clamp range, causing pinching accidents.

[0005] The utility model is realized by the following technical solutions:

[0006] The utility model proposes a high-stability mobile phone middle frame clamp, comprising a bottom plate, a fixing column is fixedly installed on the top surface of the bottom plate, a mold plate is fixedly installed on the top of the fixing column, a pressing clamping mechanism is arranged on the side of the mold plate, a longitudinal limiting mechanism is installed on the bottom surface of the mold plate, the pressing clamping mechanism comprises a top plate, the top plate is arranged on the top of the mold plate, a cylinder A is fixedly installed on the side of the mold plate, a pressing block is rotatably connected to the output end of the cylinder A, a mounting block is fixedly installed on the side of the mold plate, a connecting plate is installed between the mounting block and the pressing block, a pressing head is fixedly installed on one end of the pressing block, and a pressing groove is opened on the side of the top plate.

[0010] Furthermore, the bending block A and the bending block B are both "L"-shaped structures, and the bending block A and the bending block B are an integral structure.

[0011] Furthermore, a placement mechanism is installed on the top surface of the mold plate, and the placement mechanism includes a placement plate, and the placement plate is fixedly installed on the top surface of the mold plate, and a rubber pad and a positioning column are fixedly installed on the top surface of the placement plate.

[0012] Furthermore, the rubber pads are made of natural rubber, and are evenly distributed on the top surface of the placement plate.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model first covers the top plate on the middle frame of the mobile phone, and then drives the pressing block and the pressing head to perform the pressing operation through the cylinder A, thereby effectively reducing the risk of the staff being pinched by directly holding the middle frame of the mobile phone during operation. The pressing area of ​​the pressing head is small, which is not easy to pinch the operator and can ensure the concentration of the pressing force, thereby further avoiding harm to the operator. In addition, the design of driving the bending blocks A and B through the cylinder B can enter the insertion groove through the bending parts above the bending blocks A and B after fixing the middle frame of the mobile phone, so as to achieve left and right limit of the top plate, avoid the shaking displacement of the top plate to the front and back, left and right during the processing, which not only ensures the positioning accuracy during the processing, but also improves the stability of the entire clamping structure, thereby ensuring the processing quality.

[0015] 2. In the utility model, the placement plate can be used to place the middle frame of the mobile phone, and the rubber pad can be used to effectively improve the protection effect. When clamping the middle frame of the mobile phone, the middle frame of the mobile phone can be prevented from being worn due to hard contact. The positioning column can limit the position of the middle frame of the mobile phone, thereby ensuring accuracy during subsequent clamping. The utility model arranges a rubber pad on the placement plate. When the middle frame of the mobile phone is placed on the clamp, the hard contact between the middle frame of the mobile phone and the clamp can be effectively prevented, thereby avoiding wear or scratches on the middle frame of the mobile phone during the clamping process. By introducing the positioning column, the position of the middle frame of the mobile phone can be accurately limited before clamping, ensuring that the position of the middle frame of the mobile phone remains fixed during processing or testing.

[0024] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0025] Please refer to Figure 1-Figure 6 The utility model proposes a high-stability mobile phone middle frame clamp, including a bottom plate 1, a fixed column 2 is fixedly installed on the top surface of the bottom plate 1, a mold plate 3 is fixedly installed on the top of the fixed column 2, a downward clamping mechanism 4 is arranged on the side of the mold plate 3, and a longitudinal limit mechanism 5 is installed on the bottom surface of the mold plate 3. The fixed columns 2 are evenly distributed on the top surface of the bottom plate 1 to provide stable support and ensure the stability of the entire clamp. Chamfers 7 are provided at the four corners of the surface of the bottom plate 1 to reduce accidental injuries caused by sharp corners and increase safety in use. The downward clamping mechanism 4 includes a top plate 401, which is arranged on the top of the mold plate 3 to provide coverage and protection for the mobile phone middle frame. A cylinder A402 is fixedly installed on the side of the mold plate 3, and a downward pressing block 403 is rotatably connected to the output end of the cylinder A402 to provide a power source so that the downward pressing block 403 can move along a specific trajectory. This rotation connection can be hinged or matched with a slide rail to achieve smooth and controllable movement. A mounting block 404 is fixedly installed on the side of the mold plate 3, and a connecting plate 405 is installed between the mounting block 404 and the lower pressing block 403, which is fixed by bolts or riveting to ensure the stability of the connection and the correct guidance of the lower pressing block 403. A lower pressing head 406 is fixedly installed at one end of the lower pressing block 403, and a pressing groove 407 is provided on the side of the top plate 401. The size of the lower pressing head 406 and the pressing groove 407 are adapted to ensure that they can be accurately matched when pressed down, and the top plate 401 is effectively pressed. This precise matching design reduces the potential damage to the mobile phone middle frame during the clamping process and improves the clamping stability. A processing groove 408 is provided on the top surface of the top plate 401 to accommodate or guide the debris or coolant generated during the processing process, reduce the pollution to the working environment, and protect the mechanical parts from erosion. The longitudinal limiting mechanism 5 includes a cylinder B501, which is fixedly installed on the bottom surface of the mold plate 3 to provide power for longitudinal movement. The top surface of the mold plate 3 is provided with a through groove 502 to allow the output end of the cylinder B501 to move. This design makes the longitudinal limit more flexible and effective. The output end of the cylinder B501 is installed with a bending block A503 and a bending block B504. The bending block A503 and the bending block B504 are both "L"-shaped structures. The bending block A503 and the bending block B504 are an integrated structure, which is made by casting or welding to ensure its structural strength and stability. The bottom surface of the top plate 401 is provided with an insertion groove 505, which matches the bending portion above the bending block A503 and the bending block B504 to achieve precise left and right limit.

[0026] The top surface of the mold plate 3 is installed with a placement mechanism 6, and the placement mechanism 6 includes a placement plate 601, and the placement plate 601 is fixedly installed on the top surface of the mold plate 3. When installing the placement plate 601, screw fixing, welding or gluing can be used to ensure that the fixed relationship between it and the mold plate 3 is stable to withstand various forces generated during the clamping process. The top surface of the placement plate 601 is fixedly installed with a rubber pad 602 and a positioning column 603. The material of the rubber pad 602 is natural rubber, which not only has good buffering performance, but also can effectively reduce the wear on the middle frame of the mobile phone. The rubber pads 602 are evenly distributed on the top surface of the placement plate 601, and the rubber pads 602 can be installed by gluing or mechanical fixing to ensure its stability and anti-slip performance during the clamping process.

[0027] In this embodiment, the mobile phone middle frame to be fixed is placed on the mold plate 3, and then the top plate 401 covers the mobile phone middle frame, and then the cylinder A402 drives the lower pressing block 403 to move upward, and the lower pressing block 403 rotates through the connecting plate 405 at this time, and then the lower pressing block 403 drives the lower pressing head 406 to rotate downward, and the lower pressing head 406 presses the pressing groove 407 downward at this time, and then the top plate 401 can be pressed tightly, and the mobile phone middle frame can be clamped and fixed by the top plate 401. Because the top plate 401 needs to be covered on the mobile phone middle frame before it can be clamped and fixed, and the downward pressing area of ​​the lower pressing head 406 is small, this can effectively avoid the staff's hands from being pinched during clamping, and after the mobile phone middle frame is fixed , the cylinder B501 drives the bending block A503 and the bending block B504 to move downward until the bending portion above the bending block A503 and the bending block B504 enters the insertion groove 505, at which time the top plate 401 can be limited left and right to prevent the top plate 401 from shaking and displacing left and right. When the cylinder B501 drives the bending block A503 and the bending block B504 to move upward, the bending portion above the bending block A503 and the bending block B504 leaves the insertion groove 505, at which time the limit can be released. The utility model effectively reduces the staff's work by first covering the top plate 401 on the middle frame of the mobile phone, and then driving the lower pressing block 403 and the lower pressing head 406 to perform the pressing operation through the cylinder A402. During operation, there is a risk of a pinching accident due to directly holding the middle frame of the mobile phone, and the pressing area of ​​the pressing head 406 is small, which can ensure that the pressing force is concentrated and further avoid harm to the operator. In addition, the design of the bending blocks A503 and B504 driven by the cylinder B501 can allow the bending blocks A503 and B504 to enter the insertion groove 505 after the middle frame of the mobile phone is fixed, so as to limit the left and right positions of the top plate 401, and avoid the shaking and displacement of the top plate 401 to the left and right during the processing, which not only ensures the positioning accuracy during the processing, but also improves the stability of the entire clamping structure. The placement plate 601 can be used to place the middle frame of the mobile phone , and the rubber pad 602 can effectively improve the protection effect. When clamping the middle frame of the mobile phone, the middle frame of the mobile phone can be prevented from being worn due to hard contact. The positioning column 603 can limit the position of the middle frame of the mobile phone, thereby ensuring the accuracy of subsequent clamping. The utility model arranges the rubber pad 602 on the placement plate 601. When the middle frame of the mobile phone is placed on the clamp, the hard contact between the middle frame of the mobile phone and the clamp can be effectively prevented, thereby avoiding wear or scratches on the middle frame of the mobile phone during the clamping process. By introducing the positioning column 603, the position of the middle frame of the mobile phone can be accurately limited before clamping, ensuring that the position of the middle frame of the mobile phone remains fixed during processing or testing.

[0028] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
