Description

Technical Field

[0001] The utility model relates to a vise, in particular to a low jaw thereof, and belongs to the technical field of tooling fixtures. Background Art

[0002] Existing electrode fixtures such as Figure 1 As shown, it includes a straight groove chuck and a number of bolts. A slot is provided in the middle of the upper surface of the straight groove chuck. One end of the electrode is inserted into the slot. The bolt is screwed to one side wall of the slot. One side of the electrode is aligned with one end of the straight groove chuck. Then the bolt is tightened. The top of the bolt abuts against the electrode. The electrode is clamped by the bolt and the other side wall of the slot. The deeper the slot, the more secure the clamping. This type of electrode fixture has shortcomings. One end of the electrode is inserted into the slot too deep. The machine tool can only process part of the electrode on the slot. The electrode inside the slot cannot be processed. The depth of the slot is as shown in FIG. Figure 1 As shown in A. The unprocessed part of the electrode is ineffective and the electrode material is wasted.

[0003] In addition, the electrode fixture is positioned by aligning one side of the electrode with one end of the straight groove chuck, and the center of the electrode of different sizes has a different offset distance from the center of the straight groove chuck. In order to position the electrode to the target position, it takes time to adjust the position of the electrode fixture. At present, vises are not used to clamp electrodes in the field of electrode processing. Utility Model Content

[0004] In order to overcome the above disadvantages, the purpose of the utility model is to provide a vise to solve one of the problems mentioned in the background technology part.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a vise, including a main body, a pair of first sliders, a pair of clamping blocks and a driving mechanism, a first sliding groove is opened on the main body, the pair of first sliders slide relatively in the first sliding groove under the action of the driving mechanism, a pair of clamping blocks are respectively fixedly connected to the upper ends of the pair of first sliders, and the two ends of the clamping blocks abut against the upper surface of the main body; the first slider and the clamping block are integrally formed.

[0006] The utility model is further configured as follows: the driving mechanism includes a fixed plate and a bidirectional screw rod, which is fixedly connected to the bottom of the first slide groove and has a through hole in the middle; the left and right sections of the bidirectional screw rod are respectively screwed to the pair of first sliding blocks, and an annular groove is provided in the middle, and the through hole cooperates with the annular groove.

[0007] The utility model is further configured as follows: second slide grooves are provided on both side walls of the first slide groove, and second slide blocks are connected to both side surfaces of the first slide block, and the second slide blocks are used in conjunction with the second slide grooves.

[0008] The utility model is further configured as follows: two side edges of one side opposite to the pair of first sliding blocks are configured as chamfers.

[0009] The utility model is further configured as follows: a pull rod is connected to the center of the lower surface of the body, and pull nails are connected to the four corners.

[0010] The utility model is further configured as follows: the vise is used for clamping electrodes, copper or precious metal materials.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the first slider and the clamping block are integrally formed. A clamping block with a lower height can still provide sufficient holding force to clamp precious materials such as electrodes between a pair of clamping blocks. Only a very small part of precious materials such as electrodes cannot be processed by machine tools, and more precious materials such as electrodes are exposed above the clamping blocks, and the surface that can be processed by the machine tool is larger. Technicians in the electrode processing industry believe that the existing electrode clamps are similar to vise structures, and both need to clamp a part of the electrode material, resulting in the failure to process and utilize this part of the electrode material. The vise is more complex in structure and more expensive than the existing electrode clamps. Therefore, the vise is not used. This hinders the application of the vise in the electrode processing industry. This patent application overcomes technical prejudice. Due to the high price of electrode materials, the application of the vise described in this patent application is expected to save medium-sized electrode processing companies one million yuan in electrode material costs each year.

[0012] In addition, the annular groove of the bidirectional screw rotates in the through hole of the fixed plate, and the pair of first sliders can only move relative to each other along the axial direction of the bidirectional screw due to the restriction of the first slide groove, clamping the electrode between the pair of clamping blocks. Regardless of the size of the electrode.

[0013] The above description is only an overview of the technical solution of the utility model. In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the utility model in conjunction with the accompanying drawings.

DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0020] See attached Figure 2-4 As shown, a vise in this embodiment includes a main body 5, a pair of first sliders 14, a pair of clamping blocks 17 and a driving mechanism. A first slide groove 6 is provided on the main body 5. The pair of first sliders 14 slide relatively in the first slide groove 6 under the action of the driving mechanism. A pair of clamping blocks 17 are respectively fixedly connected to the upper ends of the pair of first sliders 14, and the two ends of the clamping blocks 17 abut against the upper surface of the main body 5; the first slider 14 and the clamping block 17 are integrally formed.

[0021] The first slider 14 is confined in the first slide groove 6 and slides along the first slide groove 6. The first slider 14 and the clamp block 17 are integrally formed. The connection area between the first slider 14 and the clamp block 17 is large, and the force of the first slider 14 is transmitted to the clamp block 17. The clamp block 17 with a lower height can still provide sufficient holding force to clamp precious materials such as electrodes between a pair of clamp blocks 17. Only a very small part of precious materials such as electrodes cannot be processed by machine tools, and more precious materials such as electrodes are exposed above the clamp block 17, and the surface that can be processed by the machine tool is larger. The electrode fixture in the prior art is that the side wall of the slot and the bolt provide the clamping force, and the side wall of the slot above the bolt blocks the electrode material and cannot be processed by the machine tool.

[0022] The utility model is further configured as follows: the driving mechanism includes a fixed plate 8 and a bidirectional screw rod 12, which are fixedly connected to the bottom of the first slide groove 6 and a through hole 9 is provided in the middle; the left and right sections of the bidirectional screw rod 12 are respectively screwed to the pair of first sliding blocks 14, and a ring groove 13 is provided in the middle, and the through hole 9 cooperates with the ring groove 13.

[0023] The annular groove 13 of the bidirectional screw 12 rotates in the through hole 9 of the fixed plate 8, and the pair of first sliders 14 can only move relative to each other along the axial direction of the bidirectional screw 12 due to the restriction of the first slide groove 6, clamping the electrode between the pair of clamping blocks 17. Regardless of the size of the electrode.

[0024] In order to improve the movement accuracy of the first slider 14 , the utility model is further configured as follows: second sliders 7 are provided on both side walls of the first slider 6 , and second sliders 15 are connected to both side surfaces of the first slider 14 , and the second sliders 15 are used in conjunction with the second sliders 7 .

[0025] In order to prevent the debris generated during processing from gathering inside the first slide groove 6 and hindering the movement of the first slider 14, the utility model is further configured as follows: the two sides of the opposite side of the pair of first sliders 14 are configured as chamfers 16. The debris is pushed to the chamfers 16 by the first slider 14, and the chamfers 16 accommodate the debris to prevent the debris from hindering the movement of the first slider 14.

[0026] In order to facilitate the connection between the vise and the machine tool, the utility model is further configured as follows: a pull rod 10 is connected to the center of the lower surface of the body 5, and pull pins 11 are connected to the four corners.

[0027] The utility model is further configured as follows: the vise is used for clamping electrodes, copper or precious metal materials.

[0028] Technicians in the electrode processing industry believe that the existing electrode fixtures are similar to vises in structure, and both need to clamp a portion of the electrode material, resulting in the failure to process and utilize this portion of the electrode material. The vise is more complex in structure than the existing electrode fixture, and the cost of the vise is higher. Therefore, the vise is not used. This hinders the application of the vise in the electrode processing industry. This patent application overcomes technical prejudice. The first slider 14 and the clamping block 17 are integrally formed. The first slider 14 is confined in the first slide groove 6 and slides along the first slide groove 6. The connection area between the first slider 14 and the clamping block 17 is large, and the force of the first slider 14 is transmitted to the clamping block 17. The clamping block 17 with a lower height can still provide sufficient holding force to clamp precious materials such as electrodes between a pair of clamping blocks 17. Only a very small part of precious materials such as electrodes cannot be processed by machine tools, and more precious materials such as electrodes are exposed above the clamping block 17, and the surface that can be processed by the machine tool is larger.

[0029] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
