Description

Technical Field

[0001] This utility model relates to the field of tooling fixture technology, and in particular to a slant-pressure type tooling fixture. Background Technology

[0002] Tooling fixtures are mainly used to fix parts in the process of machining or inspection and testing, so as to ensure that the position of the parts does not shift during machining or inspection, thereby obtaining more perfect accuracy.

[0003] When clamping sheet metal, traditional tooling fixtures are usually pressed on the edge of the sheet metal. If the entire sheet metal surface needs to be processed, this clamping method of pressing on the sheet metal cannot be completed in one go. The part pressed by the fixture needs to be processed separately. Although it is also possible to continue positioning and clamping by pressing the side of the sheet metal, the conventional drive cylinder body installed on the processing table will occupy a lot of space and make the table look less neat.

[0004] Therefore, those skilled in the art provide a slant-pressure type tooling fixture to solve the problems mentioned in the background art. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a slanted pressing type tooling fixture, including a tooling plate, a detachable stop block installed on one of the upper sides of the tooling plate, a downward vertical assembly hole opened on the tooling plate, a cylinder body installed in the assembly hole, the bottom opening of the cylinder body forming a cylinder bore, the cylinder bore being inclined, a piston installed in the cylinder bore, a telescopic rod fixedly installed at the upper end of the piston perpendicular to it, the telescopic rod moving obliquely along the cylinder bore as the piston moves, a wedge-shaped locking block installed on the upper part of the telescopic rod, a limiting groove opened on the end face of the wedge-shaped locking block opposite to the stop block, a clamping component that can slide and adjust relative to it in the limiting groove, and a positioning component for positioning it on the clamping component.

Positioning blocks are integrally provided on both sides of the upper part of the slider. Circular holes are opened on the positioning blocks. Vertical fixing screws are inserted into the circular holes. The fixing screws are threadedly connected to the top of the wedge-shaped locking block. The fixing screws are used to fix the positioning blocks.

[0008] Preferably, the positioning component includes fixing blocks symmetrically fixed on both sides of the wedge-shaped locking block, with a vertically upward positioning screw threaded onto the fixing block. The top of the positioning screw lifts the positioning block, thereby positioning the positioning block and thus positioning the clamping component. In conjunction with the fixing screw, the height of the clamping component is fixed.

[0009] Preferably, the wedge-shaped locking block has a mounting hole that engages with the upper part of the telescopic rod, making the wedge-shaped locking block and the telescopic rod detachable.

[0010] Preferably, the top of the telescopic rod is threaded to connect to the mounting bolt, and multiple expansion grooves are equally spaced on the upper part. During the tightening of the mounting bolt, the upper part of the telescopic rod will be expanded in the mounting hole, making the connection between the telescopic rod and the wedge-shaped locking block more secure and stable.

[0011] Preferably, a guide hole is provided on the upper part of the cylinder body corresponding to the inner hole of the cylinder barrel. The guide hole guides the telescopic rod. A mating groove is provided on the upper end of the cylinder body corresponding to the guide hole.

[0012] Preferably, the inner arc of the guide bracket fixed at the corresponding mating groove on the top of the cylinder body is adapted to the arc of the wedge-shaped locking block, and the wedge-shaped locking block moves along the inner arc of the guide bracket during the movement.

[0013] The technical effects and advantages of this utility model are as follows: Compared with the prior art, the beneficial effects of this utility model are: 1. The tooling plate of this utility model has a downward vertical assembly hole. The cylinder is installed in the assembly hole. When the piston and telescopic rod of the cylinder move upward, they move in an oblique upward direction. During this process, the clamping component moves obliquely upward away from the clamped part, and the part can be moved. When the piston drives the telescopic rod to move obliquely downward, the clamping component moves obliquely downward to clamp the part, thereby achieving clamping and fixing of the part. The structure layout is reasonable and the structure is simplified. The cylinder is buried inside the tooling, occupying very little space and making the tooling appearance simple. The modular design makes the tooling design simple and reliable.

A vertically upward positioning screw is threaded onto the fixed block. The top of the positioning screw lifts the positioning block and positions it, thereby positioning the clamping component. With the help of the fixed screw, the height of the clamping component can be fixed, making the clamping component suitable for plate-shaped workpieces of different thicknesses, and thus applicable to a wider range of scenarios.

[0015] 3. In this utility model, the inner arc of the guide bracket fixed at the corresponding mating groove on the top of the cylinder body is adapted to the arc of the wedge-shaped locking block. During the movement, the wedge-shaped locking block moves along the inner arc of the guide bracket. The guide bracket has a limiting effect on the wedge-shaped locking block and also has a supporting effect on the wedge-shaped locking block, making the working state of the wedge-shaped locking block more stable.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] Example 1 Please see Figure 1-7 This embodiment provides a slant-type tooling fixture, including a tooling plate 22. A detachable stop 23 is installed on one side of the upper end of the tooling plate 22. The stop 23 is fixed to the tooling plate 22 by bolts. The installation position of the stop can be adjusted according to the size of the part. A downward vertical assembly hole is opened on the tooling plate 22. A cylinder body 1 is installed in the assembly hole. The bottom opening of the cylinder body 1 forms a cylinder bore. The cylinder bore is inclined. A piston 15 is installed in the cylinder bore. A telescopic rod 14 perpendicular to the piston 15 is fixedly installed at the upper end of the piston 15. The telescopic rod 14 moves obliquely along the cylinder bore as the piston 15 moves. A wedge-shaped locking block 3 is installed on the upper part of the telescopic rod 14. The wedge-shaped locking block 3 is positioned opposite the stop. A limiting groove 16 is provided on the end face of 23. A clamping component that can slide and adjust relative to it is provided in the limiting groove 16. A positioning component is provided on the clamping component to position it. The positioning component is used to position the clamping component. When the piston 15 and the telescopic rod 16 move upward, they move in an oblique upward direction. During this process, the clamping component moves obliquely upward away from the clamped part, and the part can be moved. When the piston 15 drives the telescopic rod 14 to move obliquely downward, the clamping component moves obliquely downward to clamp the part, thereby achieving clamping and fixing of the part. The structure layout is reasonable and the structure is simplified. The cylinder body 1 is buried inside the tooling, occupying very little space and making the tooling appearance simple. The modular design makes the tooling design simple and reliable.

[0020] The end face of the wedge-shaped locking block 3 opposite to the stop block 23 is perpendicular to the upper surface of the tooling plate 22. This ensures that the clamping component after installation is perpendicular to the clamped part, resulting in a better clamping angle.

[0021] A spring 19 is installed at the lower part of the inner bore of the cylinder body 1. A transverse groove 11 is opened at the bottom opening of the cylinder body 1, and a pad 20 is installed in the groove 11. The bottom surface of the pad 20 coincides with the bottom surface of the mounting hole, and the top surface of the pad 20 supports the spring 19. A vertically upward hydraulic channel 18 is opened on one side of the bottom of the cylinder body 1, and the top of the hydraulic channel communicates with the inner bore of the cylinder. A hydraulic input port 24 is opened at the bottom of the tooling plate 22, and the top of the hydraulic input port 24 communicates with the hydraulic channel 18. An exhaust port 25 is opened at the bottom of the tooling plate 22. The top is connected to the inner hole of the cylinder. Hydraulic material is input through the hydraulic input port 24 to provide positive pressure. The piston 15 and the telescopic rod 14 move diagonally downward. The piston 15 squeezes the spring 19. During the diagonal downward movement of the wedge-shaped locking block 3, the side or top surface of the workpiece is squeezed (which can be selected according to the processing requirements of the workpiece). Negative pressure is provided to the hydraulic input port 2 to extract the hydraulic material. The pressure at the upper end of the piston 15 decreases, and the spring 19 is released. Under the action of its elastic force, the piston 15 and the telescopic rod 14 are pushed up. During this process, the wedge-shaped locking block 3 disengages from the workpiece. At this time, the workpiece can be picked up and put down.

[0022] The clamping component includes a slider 6, a positioning block 7, and a clamping plate 5. The slider 6 is a T-shaped block that mates with the limiting groove 16. The protruding end of the slider 6 is integrally connected to the clamping plate 5. The clamping plate 5 is used to contact and clamp the workpiece. Positioning blocks 7 are integrally provided on both sides of the upper part of the slider 6. Circular holes are opened on the positioning blocks 7, and vertical fixing screws 8 are inserted into the circular holes. The fixing screws 8 are threadedly connected to the top of the wedge-shaped locking block 3. The fixing screws 8 are used to fix the positioning blocks 7, thereby fixing the clamping component.

[0023] The positioning component includes fixing blocks 9 symmetrically fixed on both sides of the wedge-shaped locking block 3. A vertically upward positioning screw 10 is threaded onto the fixing block 9. The top of the positioning screw 10 lifts the positioning block 7, thereby positioning the positioning block 7 and thus positioning the clamping component. With the fixing screw, the height positioning and fixing of the clamping component can be achieved, making the clamping component suitable for plate-shaped workpieces of different thicknesses, and thus applicable to a wider range of scenarios.

[0024] By combining clamping and positioning components, it can be used for workpieces of different thicknesses, and the workpiece can be clamped on the side or the top edge of the workpiece according to the processing requirements.

[0025] The wedge-shaped locking block 3 has a mounting hole 21, which is connected to the upper part of the telescopic rod 14, so that the wedge-shaped locking block 3 and the telescopic rod 14 can be disassembled.

[0026] The top of the telescopic rod 14 is threaded to install bolt 4, and multiple expansion grooves 17 are equally spaced on the upper part. During the tightening of the installation bolt 4, the upper part of the telescopic rod 14 will be opened in the installation hole 21, making the connection between the telescopic rod 14 and the wedge-shaped locking block 3 more secure and stable.

[0027] A guide hole 13 is provided on the upper part of the cylinder body 1 corresponding to the inner hole of the cylinder barrel. The guide hole 13 guides the telescopic rod 14. A mating groove 12 is provided on the upper end of the cylinder body 1 corresponding to the guide hole 13. The mating groove 12 is an inclined groove. The mating groove 12 mates with the bottom surface of the wedge-shaped locking block 3. When clamping the workpiece, the bottom surface of the wedge-shaped locking block 3 fits more closely with the top of the cylinder body 1, and the force is more even.

[0028] The inner arc of the guide support 2, which is fixed at the top of the cylinder 1 corresponding to the mating groove 12, matches the arc of the wedge-shaped locking block 3. During the movement, the wedge-shaped locking block 3 moves along the inner arc of the guide support 2. The guide support 2 has a limiting effect on the wedge-shaped locking block 3 and also supports the wedge-shaped locking block 3, making the working state of the wedge-shaped locking block 3 more stable.

[0029] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
