Description

Technical Field

[0001] The utility model relates to the field of tooling fixtures, in particular to a tooling fixture for processing cavity-type workpieces. Background Art

[0002] Cavity workpiece processing tooling is a general term for various tools used to process cavity workpieces during the manufacturing process. Tooling can ensure the accurate position of the workpiece during the processing, avoid displacement or deformation of the workpiece during the processing, and ensure processing accuracy. Tooling can firmly clamp the workpiece on the processing equipment to prevent the workpiece from loosening or falling off during the processing, ensuring the safety and stability of the processing process.

[0003] In the current field of mechanical processing, cavity workpieces have always been one of the most difficult types of workpieces to process due to their unique internal structure and complex geometric shapes. Such workpieces usually contain cavities of different shapes and sizes, such as arc-shaped cavities, which require not only high machining precision, but also the stability and positioning accuracy of the workpiece during machining.

[0004] However, the adaptability of existing processing tools to cavity-type workpieces is generally low, especially when processing arc-shaped workpieces in the cavity, the positioning effect is often unsatisfactory. The tooling design often uses fixed fixtures or positioning devices, which are difficult to adapt to cavity-type workpieces of different shapes and sizes, resulting in reduced processing accuracy and even possible damage to the workpiece. The processing tooling also lacks sufficient adjustment range, which makes it difficult to clamp cavity-type workpieces of different sizes. Utility Model Content

[0049] The fastener 3 includes: two nuts 301, installed on the top of the fastener 3; two screw rods 303, which penetrate the fastener 3 and are connected to the corresponding two nuts 301; two connecting heads 302, which are respectively installed on the top of the two screw rods 303 and are used to control the rotation of the screw rods 303; the tops of the two positioning seats 2 are provided with thread grooves, and the screw rods 303 are connected in the thread grooves. By rotating the two connecting heads 302, the nuts 301 and the fastener 3 can be driven by the screw rods 303 to move on the screw rods 303, thereby achieving stable fixation of the workpiece, ensuring the stability of the workpiece during the processing, reducing processing errors, and improving processing quality. The cooperation between the thread groove on the top of the positioning seat 2 and the screw rod 303 enables the fastener 3 to be accurately positioned above the workpiece, and compression is achieved by rotating the screw rod 303, which not only simplifies the tooling structure, but also improves the convenience and safety of operation.

[0050] Reference Figure 2The stabilizing mechanism 4 includes: a moving groove 401, which is opened at the bottom of the fastener 3; a moving plate 405, which is connected to the moving groove 401 and is configured to be movable up and down in the moving groove 401; a positioning member 402, which is installed at the bottom of the moving plate 405 and is used to assist the fastener 3 in fixing the workpiece; the positioning member 402 is cylindrical and is used to fit the workpiece; a screw rod 404, one end of which is connected to the moving plate 405, and the other end of which passes through the top wall of the moving groove 401 and extends to the outside of the fastener 3; a knob 403, which is arranged on the top of the fastener 3 and is connected to the screw rod 40 4 is connected to the top of the workpiece, and the stabilizing mechanism 4 provides additional support and fixing force for the fastener 3. The moving plate 405 moves up and down in the moving groove 401, and can be precisely adjusted by the control of the knob 403 and the screw rod 404, ensuring that the positioning member 402 can fit closely to the surface of the workpiece, thereby improving the stability of the fixation. The cylindrical positioning member 402 can fit the surface contour of the workpiece, increasing the contact area, further improving the firmness and stability of the fixation, and is particularly suitable for the curved surface in the cavity-type workpiece, thereby improving the adaptability and application range of the tooling.

[0051] Reference Figure 2 The mounting seat 1 includes: two adjustment slots 101 , which are opened at the top of the mounting seat 1 ; two adjustment seats 102 , which are respectively connected to the two adjustment slots 101 , and the positioning seat 2 is connected to the top of the adjustment seat 102 .

[0052] Reference Figure 3-Figure 5 The adjusting seat 102 includes: a through hole 103, which is opened on one side of the adjusting seat 102; two support blocks 104, which are installed in the through hole 103 and are arranged to contact the inner wall of the adjusting groove 101 when they are far away from each other, and are used to fix the adjusting seat 102 in the adjusting groove 101; an extrusion block 105, which is installed in the through hole 103 and is arranged between the two support blocks 104, and is used to squeeze the two support blocks 104; a rotating shaft 106, one end of which is installed on the extrusion block 105, and the other end passes through the top wall of the through hole 103 and is connected to the bottom of the positioning seat 2, and the adjusting seat 102 is through The combination of the support block 104 and the extrusion block 105 in the through hole 103 realizes a firm locking with the adjustment groove 101. When the support blocks 104 move away from each other, they are in close contact with the inner wall of the adjustment groove 101, preventing the adjustment seat 102 from moving and loosening, thereby ensuring the stability of the positioning seat 2 during the processing. The rotating shaft 106 is connected between the extrusion block 105 and the positioning seat 2, thereby realizing precise adjustment of the angle and position of the positioning seat 2, so that the tooling can adapt to the processing requirements of workpieces with different angles and inclinations, thereby improving the flexibility and adaptability of the tooling.

[0053] During use, the distance between the two positioning seats 2 is adjusted according to the size of the workpiece. When adjusting, the positioning seat 2 is rotated, and the positioning seat 2 drives the rotating shaft 106 to rotate. The rotating shaft 106 drives the extrusion block 105 to rotate. The extrusion block 105 squeezes the two support blocks 104 at the same time. The support blocks 104 move in the through hole 103. When the support blocks 104 move away from each other, they are in close contact with the inner wall of the adjustment groove 101 to achieve the fixation of the adjustment seat 102. The workpiece is placed between the two positioning seats 2 to ensure that the workpiece is in good contact with the positioning seats 2. If the workpiece has an inclined angle or a special shape, the angle and position of the positioning seat 2 can be further fine-tuned by the rotating shaft 106 on the adjustment seat 102 to adapt to the workpiece. The two connectors on the rotating fastener 3 302, drives the screw rod 303 to rotate, so that the fastener 3 approaches the positioning seat 2 until the fastener 3 contacts the surface of the workpiece and applies appropriate pressure. The two nuts 301 on the fastener 3 cooperate with the screw rod 303 to ensure that the fastener 3 moves stably on the screw rod 303, so as to achieve stable fixation of the workpiece. Rotate the knob 403 to make the screw rod 404 drive the moving plate 405 to move in the moving groove 401, and the positioning piece 402 at the bottom of the moving plate 405 moves accordingly until the positioning piece 402 fits tightly to the surface of the workpiece, especially the arc surface part of the workpiece. The cylindrical positioning piece 402 can fit the surface contour of the workpiece, increase the contact area, and improve the firmness and stability of the fixation. After the workpiece is fixed, the processing operation of the cavity workpiece is started.
