Description

Technical Field

[0001] This utility model relates to the field of clamping tooling technology, and in particular to a multi-applicable clamping tooling. Background Technology

[0002] Clamping fixtures are used to hold and fix parts during machining, thereby ensuring the correct relative position of the parts during assembly.

[0003] In traditional clamping fixtures, the control device slowly moves the clamp to make gentle contact with the workpiece, and gradually applies clamping pressure to the workpiece according to the processing requirements. However, most clamping fixtures are designed to fit specific products and often do not have the function of changing the clamp, resulting in a narrow range of applications. Once faced with other structures, they are difficult to clamp and are prone to workpiece displacement, affecting the processing accuracy. Therefore, it is necessary to improve the existing technology to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a versatile clamping fixture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A versatile clamping fixture includes a base and a clamping block. A clamping platform is fixedly connected to the upper surface of the base. A cavity is formed inside the clamping platform, and two sliders are slidably connected inside the cavity. A driving component for moving the sliders is provided inside the cavity. A square rod is fixedly connected to the top of the sliders. A guide groove communicating with the cavity is formed on the top of the clamping platform, and the square rod passes through the guide groove. A square hole adapted to the square rod is formed on the top of the clamping block, and the square rod passes through the square hole, allowing the clamping block to move along the square rod. A stop block supporting the clamping block is fixedly connected to the outer side of the square rod above the base. A sliding groove is formed at the top of the square rod, and two semi-conical blocks for blocking and limiting the clamping block are slidably connected inside the sliding groove. A spring is fixedly connected between the two semi-conical blocks.

[0007] As a further embodiment of this utility model, the driving assembly includes a bidirectional lead screw, which is rotatably connected in the cavity. The bidirectional lead screw passes through two sliders and is threadedly connected to the two sliders. One end of the bidirectional lead screw passes through the clamping platform and is fixedly connected to a throttle. The bottom of the cavity is provided with a guide assembly that enables the sliders to move horizontally.

[0008] As a further embodiment of this utility model, the guide component includes a dovetail groove, which is formed at the bottom of the cavity. Two dovetail blocks are slidably connected inside the dovetail groove, and the two dovetail blocks are respectively fixed to two sliders.

[0009] As a further embodiment of this utility model, the upper surface of the base is provided with a plurality of positioning holes, which are evenly and symmetrically distributed on both sides of the guide groove, and an eccentric positioning pin is inserted into each of the plurality of positioning holes.

[0010] As a further embodiment of this utility model, threaded holes are provided at the four corners of the base, and screws are threaded into the threaded holes, with rubber pads fixedly connected to the bottom of the screws.

[0011] As a further improvement of this utility model, a level is fixedly connected to one side of the clamping platform.

[0012] As a further embodiment of this utility model, a protective pad is fixedly connected to one side of the clamping block, and the protective pad is of the same specification as the clamping block.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By using the semi-conical block and the stop block together, the two semi-conical blocks are pressed and moved towards each other along the slide groove, so that the semi-conical block no longer limits the clamping block. At this time, the clamping block can be removed from the square rod, and then different clamping blocks can be replaced to fit the workpiece being clamped, thus improving the applicability of the clamping fixture.

[0015] 2. By setting the screw, rotating the screw will cause it to move through the thread engagement with the threaded hole, thereby changing the height of the screw supporting the base and adjusting the height of the clamping fixture. This makes it easier for workers to process the clamped parts and improves the ease of use of the clamping fixture.

[0016] 3. By setting up protective pads, when clamping and fixing parts, the protective pads can prevent the clamping blocks from damaging the surface of the parts, and at the same time increase the friction between the clamping blocks and the parts, thereby stably clamping the parts and improving the effectiveness of the clamping fixture.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3 A versatile clamping fixture includes a base 1 and a clamping block 5. A clamping platform 2 is bolted to the upper surface of the base 1. The clamping platform 2 has a cavity, and two sliders 14 are slidably connected within the cavity. A drive assembly for moving the sliders 14 is provided within the cavity. A square rod 12 is welded to the top of the sliders 14. A guide groove 6 communicating with the cavity is provided on the top of the clamping platform 2, and the square rod 12 passes through the guide groove 6. A square hole adapted to the square rod 12 is provided on the top of the clamping block 5, and the square rod 12 passes through the square hole, allowing the clamping block 5 to move along the square rod 12. A stop block 16 supporting the clamping block 5 is welded to the outer side of the square rod 12 above the base 1. A sliding groove 19 is provided at the top of the square rod 12, and two semi-conical blocks 18 for blocking and limiting the clamping block 5 are slidably connected within the sliding groove 19. A spring 17 is welded between the two semi-conical blocks 18, pushing the two semi-conical blocks 18 to move towards each other along the sliding groove 19. The semi-conical block 18 will compress the spring 17 and prevent the semi-conical block 18 from blocking and limiting the clamping block 5. At this time, the clamping block 5 can be removed from the square rod 12. Then, the square rod 12 is passed through the square hole on the new clamping block 5, and the new clamping block 5 is placed on the stop block 16. Then, the semi-conical block 18 is released. At this time, the two semi-conical blocks 18 will reset under the force of the spring 17, so that the semi-conical block 18 blocks and limits the new clamping block 5. Thus, the new clamping block 5 can be installed on the square rod 12. By changing different clamping blocks 5 to adapt to the clamped workpiece, the applicability of the clamping fixture is improved.

[0024] In this utility model, the driving component includes a bidirectional lead screw 13, which is rotatably connected in the cavity. The bidirectional lead screw 13 passes through two sliders 14 and is threadedly connected to the two sliders 14. One end of the bidirectional lead screw 13 passes through the clamping platform 2 and is welded with a handle 7. The bottom of the cavity is provided with a guide component that allows the sliders 14 to move horizontally. When the part is placed on the clamping platform 2, the bidirectional lead screw 13 is rotated. The bidirectional lead screw 13 will drive the two sliders 14 to move towards each other through the threaded engagement between the two sliders 14. The two sliders 14 will drive the square rod 12 to move the clamping block 5, so that the clamping block 5 clamps and fixes the part. The guide component includes a dovetail groove 11, which is opened at the bottom of the cavity. Two dovetail blocks are slidably connected in the dovetail groove 11. The two dovetail blocks are fixed to the two sliders 14 respectively. During the movement of the sliders 14, the dovetail blocks will move along the dovetail groove 11, so that the sliders 14 move horizontally and ensure that the clamping block 5 moves horizontally.

[0025] Multiple positioning holes 3 are provided on the upper surface of the base 1. These positioning holes 3 are evenly and symmetrically distributed on both sides of the guide groove 6. An eccentric positioning pin 4 is inserted into each of the positioning holes 3. After the part is placed on the clamping platform 2, the eccentric positioning pin 4 is inserted into the positioning hole 3 closest to the part, so that the eccentric positioning pin 4 blocks and limits the part, preventing the part from shifting to the left or right. Threaded holes are provided at the four corners of the base 1. Screws 9 are threaded into the threaded holes. Rubber pads 8 are glued to the bottom of the screws 9. Rotating the screws 9 will cause them to move through the thread engagement with the threaded holes, thereby changing the height of the screws 9 supporting the base 1 and adjusting the height of the clamping fixture. A level 10 is fixed to one side of the clamping platform 2 by bolts. The level 10 can detect the levelness of the base 1 after the height is adjusted, thereby ensuring that the clamping fixture is in a horizontal state. A protective pad 15 is glued to one side of the clamping block 5, and the protective pad 15 is the same size as the clamping block 5.

[0026] Working principle: When replacement is needed, push the two semi-conical blocks 18 to move towards each other along the slide groove 19. The two semi-conical blocks 18 will compress the spring 17 and prevent the semi-conical blocks 18 from blocking and limiting the clamping block 5. At this time, the clamping block 5 can be removed from the square rod 12. Then, let the square rod 12 pass through the square hole on the new clamping block 5 and place the new clamping block 5 on the stop block 16. Then release the semi-conical blocks 18. At this time, the two semi-conical blocks 18 will reset under the force of the spring 17, so that the semi-conical blocks 18 block and limit the new clamping block 5, thereby installing the new clamping block 5. The clamping tool is mounted on the square rod 12, allowing for the replacement of different clamping blocks 5 to fit the workpiece, thus improving the applicability of the clamping fixture. The part is then placed on the clamping platform 2, and the eccentric positioning pin 4 is inserted into the positioning hole 3 near the part. The eccentric positioning pin 4 blocks and limits the part, preventing it from shifting to the left or right. Then, the bidirectional lead screw 13 is rotated. The bidirectional lead screw 13, through its thread engagement with the two sliders 14, causes the two sliders 14 to move towards each other. The two sliders 14 then drive the square rod 12 to move the clamping blocks 5, thus clamping and fixing the part.

[0027] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
