Description

Technical Field

[0001] This utility model relates to the field of clamping tooling technology, specifically a tooling fixing structure. Background Technology

[0002] Tooling fixtures are devices or systems used to fix and position workpieces in industrial production processes. These structures typically include clamps, locating pins, and clamping devices to ensure the workpiece maintains a stable and accurate position during processing. The design and use of tooling fixtures are crucial for improving production efficiency, ensuring product quality, and guaranteeing operational safety.

[0003] Common tooling fixing structures include a main body, a screw, and a clamping plate. In use, the workpiece is first placed inside the clamping plate, and then the clamping plate is closed by rotating the screw, thus clamping it. However, this method cannot adapt to different angle processing requirements because the angle of the workpiece is fixed after it is fixed. This results in repeated disassembly and assembly when the angle of the workpiece needs to be adjusted, which affects the clamping accuracy of the tooling fixing structure and cannot meet the working requirements of clamping tooling. Therefore, a tooling fixing structure is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tooling fixing structure to solve the technical problem that, since the angle of the workpiece is fixed after fixing, it cannot adapt to different angle processing requirements, resulting in the need for repeated disassembly and assembly when the workpiece angle needs to be adjusted.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling fixing structure, comprising:

[0006] The base plate has a snap-fit ​​seat installed on the top left side and a mounting platform connected to the top right side of the base plate. A lead screw is screwed into the upper inside of the mounting platform, and a transmission block is inserted into the upper inside of the snap-fit ​​seat via a rotating shaft.

[0007] The slot is located in the middle of the front and rear sides of the card seat. A C-shaped bracket is inserted inside the slot. A through groove is opened on the lower side of the inside of the transmission block. A transmission rod is inserted inside the through groove.

[0008] A sliding groove is formed inside the slot, and the sliding groove passes through the corresponding position inside the card seat. Both the front and rear ends of the transmission rod are connected to the corresponding positions inside the shaped frame. A frustum is installed at the top of the transmission block. A bearing plate is installed on the top of the frustum. An installation plate is installed on the top of the bearing plate. A clamp is installed on the upper surface of the installation plate.

[0009] Preferably, a bearing bracket is installed on the middle right side of the C-shaped frame, the left end of the lead screw is connected to the inner ring of the bearing bracket, and a turntable is coaxially installed on the right end of the lead screw to facilitate rotation.

[0010] Preferably, the lower four corners of the clamp are connected to the mounting plate by bolts, and the bottom of the transmission block is L-shaped, which facilitates the replacement of different clamps by bolt installation.

[0011] Preferably, a bracket is connected to the top front side of the card holder, and a screw is screwed into the inside of the bracket. A limit block is coaxially installed at the top end of the screw, and the top edge of the limit block is rounded. The limit block can be moved up and down by rotating the screw.

[0012] Preferably, a handwheel is coaxially mounted on the bottom end of the screw, and a limiting hole is circumferentially opened on the bottom of the mounting plate at a position corresponding to the limiting block. The rotation of the mounting plate can be restricted by inserting the limiting block into the limiting hole.

[0013] Preferably, the outer side of the mounting plate is circumferentially marked with marking lines corresponding to the limiting holes, and a marking piece is connected to the middle of the front part of the bracket.

[0014] Compared with the prior art, the present invention provides a tooling fixing structure, which has the following beneficial effects:

[0015] This tooling fixing structure uses a rotating lead screw to drive the movement of the mortise frame, which in turn pulls the transmission block to tilt via a transmission rod. This allows for adjustment of the tilt angle of the vise, enabling the workpiece to be tilted without loosening the clamping device. This makes the machining process more flexible and adaptable to machining requirements at different angles. Furthermore, since the workpiece does not need to be re-clamped, it reduces positioning errors that may result from re-clamping, thereby improving machining accuracy and enhancing the quality of the tooling fixing structure.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution, a tooling fixing structure, including a base plate 1, a snap-fit ​​seat 2, a mounting platform 3, a lead screw 4, a transmission block 5, a slot 6, a U-shaped frame 7, a bearing frame 8, a through groove 9, a turntable 10, a transmission rod 11, a sliding groove 12, a frustum 13, a bearing plate 14, a mounting plate 15, a vise 16, a bracket 17, a screw 18, a limiting block 19, a limiting hole 20, a marking line 21, a marking piece 22, and a handwheel 23.

[0026] Please see Figure 1 A snap-fit ​​seat 2 is installed on the top left side of the base plate 1, and a mounting platform 3 is connected to the top right side of the base plate 1. A lead screw 4 is screwed onto the upper side of the interior of the mounting platform 3. Please refer to [link / reference]. Figure 2 The upper side of the card holder 2 is fitted with a transmission block 5 via a rotating shaft;

[0027] Please see Figure 3 Slot 6 is located in the middle of the front and rear sides of the card holder 2. A U-shaped bracket 7 is inserted inside slot 6. (See attached image.) Figure 4 The transmission block 5 has a through groove 9 on its lower interior side, and a transmission rod 11 is inserted into the through groove 9.

[0028] Please see Figure 5 The slide groove 12 is formed inside the slot 6, and the slide groove 12 passes through the corresponding position inside the card holder 2. Both the front and rear ends of the transmission rod 11 are connected to the corresponding positions inside the shaped bracket 7. Please refer to [link / reference]. Figure 4 A frustum 13 is mounted on the top of the transmission block 5. Please refer to [link / reference]. Figure 6 The top of the frustum 13 is fitted with a bearing disc 14, and the top of the bearing disc 14 is fitted with a mounting disc 15. Please refer to [link / reference]. Figure 1 The upper surface of the mounting plate 15 is equipped with a clamp 16. Please refer to [link / reference]. Figure 3 A bearing bracket 8 is installed in the middle of the right side of the C-shaped bracket 7. The left end of the lead screw 4 is connected to the inner ring of the bearing bracket 8. Please refer to [link / reference]. Figure 1 A turntable 10 is coaxially mounted on the right end of the lead screw 4. The four lower corners of the clamp 16 are connected to the mounting plate 15 by bolts. The bottom of the transmission block 5 is L-shaped. By rotating the lead screw 4, the movement of the convex frame 7 is driven, which in turn can pull the tilt of the transmission block 5 through the transmission rod 11, thereby adjusting the tilt angle of the clamp 16. This allows the workpiece to be tilted without loosening the clamping device, making the processing more flexible and adaptable to different angle processing requirements. Furthermore, since the workpiece does not need to be re-clamped, the positioning error that may be caused by re-clamping is reduced, thereby improving the processing accuracy and enhancing the quality of the tooling fixing structure.

[0029] Please see Figure 6 and Figure 7 A bracket 17 is connected to the top front side of the snap-fit ​​seat 2. A screw 18 is screwed into the inside of the bracket 17. A limit block 19 is coaxially installed at the top of the screw 18, and the top edge of the limit block 19 is rounded. A handwheel 23 is coaxially installed at the bottom of the screw 18. A limit hole 20 is circumferentially opened at the bottom of the mounting plate 15 corresponding to the position of the limit block 19. Marking lines 21 are circumferentially installed at the positions corresponding to the limit holes 20 on the outer side of the mounting plate 15. A marking piece 22 is connected to the middle of the front part of the bracket 17. The added bearing plate 14 allows the mounting plate 15 and the clamp 16 to rotate, which facilitates the adjustment of the circumferential position of the clamp 16. At the same time, the limit block 19 can be driven to move up and down and be inserted into the limit hole 20 by rotating the screw 18, thereby restricting the rotation of the mounting plate 15 and improving the practicality of the tooling fixing device.

[0030] This solution uses the rotating lead screw 4 to drive the movement of the mortise frame 7, which in turn pulls the tilt of the transmission block 5 via the transmission rod 11, allowing adjustment of the tilt angle of the clamping table 16. This enables the workpiece to be tilted without loosening the clamping device, making the machining process more flexible and adaptable to machining requirements at different angles. Furthermore, since the workpiece does not need to be re-clamped, the positioning error that may be caused by re-clamping is reduced, thereby improving machining accuracy and enhancing the quality of the tooling fixing structure. At the same time, the added bearing plate 14 allows the mounting plate 15 and the clamping table 16 to rotate, facilitating the adjustment of the circumferential orientation of the clamping table 16. Simultaneously, the rotating screw 18 drives the limit block 19 to move up and down and insert into the limit hole 20, thereby limiting the rotation of the mounting plate 15 and improving the practicality of the tooling fixing device.
