Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp for metal processing. Background Art

[0002] In the metal processing process, in order to improve the processing accuracy and efficiency, it is necessary to use a clamp to clamp and fix the workpiece to avoid position displacement during the contact between the workpiece and the processing equipment. There are many types of clamps used to clamp metal, and flat-nose pliers are one of them. They are widely used because of their strong flexibility and easy operation.

[0003] At present, the existing flat-nose pliers are used to clamp or loosen by rotating the screw. Since the screw is always exposed to the outside, when the metal is processed such as grinding or cutting, more debris will be generated, and more debris will splash onto the outer surface of the screw, which can easily cause the screw to get stuck during rotation, thereby affecting the service life of the screw. For this reason, we propose a metal processing clamp to solve the above problem. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A metal processing clamp comprises a clamp seat 1, a support plate 2 is connected to the top of the clamp seat 1, and a threaded groove is provided inside the support plate 2, a screw rod 3 is inserted inside the threaded groove, and the end of the screw rod 3 is connected to a movable splint 4 through a bearing, and a slider is connected to the bottom end of the movable splint 4, and a slideway adapted to the slider is provided inside the clamp seat 1 to guide the movable splint 4, circular rings 5 ​​are distributed on both sides of the support plate 2, and brushes 6 are connected to the inner sides of the circular rings 5. By setting the brush 6, the debris on the outer surface of the screw rod 3 can be cleaned to prevent the debris from entering the interior of the threaded groove.

[0023] Further, see Figure 1 and Figure 3 It can be known that there are four groups of circular rings 5, and the sides of the four groups of brushes 6 are respectively connected with connecting blocks 7, and reserved holes are opened inside the connecting blocks 7. Through the arrangement of four groups of circular rings 5, and in combination with the connecting blocks 7 and the reserved holes, it is convenient for the staff to disassemble the four groups of brushes 6 that have reached the end of their service life for replacement.

[0024] Further, see Figure 3 and Figure 4 It can be known that an insertion rod 8 is inserted into the reserved hole, and an insertion groove compatible with the insertion rod 8 is opened inside the support plate 2, one end of the insertion rod 8 is connected to a fixing strip 9, and the other end of the insertion rod 8 is opened with a receiving groove, and the inner wall of the receiving groove is symmetrically connected with a spring 12, the other end of the spring 12 is connected to the groove 10, and the other end of the groove 10 is connected to a moving block 11, and the moving block 11 extends to the outside of the receiving groove. Through the mutual cooperation of the insertion rod 8 and the fixing strip 9, the connecting block 7 can be fixed to the side of the support plate 2 instead of the bolts, thereby effectively improving the efficiency of the staff in replacing the brush 6.

[0025] Further, see Figure 4 and Figure 3 It can be known that a pulling bar 14 is connected to the side of the slot 10, and a sliding groove compatible with the pulling bar 14 is opened inside the insertion rod 8. When it is necessary to remove each group of rings 5, the staff only needs to pull the pulling bar 14, thereby driving the slot 10 and the moving block 11 to move inside the receiving groove under force, so as to store the moving block 11 into the receiving groove. At this time, the staff can pull the insertion rod 8 out from the inside of the connecting block 7 and the support plate 2.

[0026] Further, see Figure 4It can be known that a card slot is symmetrically opened inside the slot 10, and a guide rod 13 is inserted inside the card slot, and both ends of the guide rod 13 are connected to the inner wall of the accommodating slot. Through the mutual cooperation of the card slot and the guide rod 13, the guiding operation of the slot 10 can be realized, thereby effectively ensuring the stability of the slot 10 and the moving block 11 during the translation process to prevent the spring 12 from being skewed.

[0027] Further, see Figure 3 and Figure 4 It can be known that a positioning block 15 is connected to the side of the circular ring 5, and a positioning groove compatible with the positioning block 15 is provided inside the support plate 2. When four groups of circular rings 5 ​​need to be installed, the staff can first engage the positioning block 15 connected to the side of the circular ring 5 into the positioning groove provided inside the support plate 2. The circular ring 5 can be pre-positioned through the mortise and tenon connection between the positioning block 15 and the support plate 2, and then the staff can insert the insertion rod 8 into the reserved hole provided inside the connecting block 7. During the insertion of the insertion rod 8, since the moving block 11 is set as an inclined surface, when it is subjected to force, it can be automatically received into the receiving groove by the elastic force of the spring 12. When the insertion rod 8 is fully inserted, the moving block 11 is reset by the elastic force of the spring 12 and extends to the outside of the receiving groove to achieve the limitation of the connecting block 7.

[0028] Further, see Figure 4 It can be seen that rubber rings 16 are equidistantly distributed on the sides of the positioning block 15, and the rubber rings 16 are tightly fitted to the inner wall of the positioning groove. By setting multiple groups of rubber rings 16, the pre-positioning effect of the ring 5 can be further guaranteed, so that it is convenient for the staff to insert the insertion rod 8 into the connecting block 7 later.

[0029] Working principle: When the utility model is in use, when it is necessary to perform processing such as cutting and grinding, the staff can first install the clamp seat 1 in a suitable position, and then place the metal to be processed between the movable splint 4 and the clamp seat 1, and then the staff can rotate the screw rod 3 and threadably cooperate with the support plate 2 to achieve the clamping of the movable splint 4. During the processing, more debris will adhere to the outer wall of the screw rod 3. When the staff removes the processed metal, the screw rod 3 can be rotated in the opposite direction, thereby driving the movable splint 4 to move above the clamp seat 1. During the rotation of the screw rod 3, it will rub against the brush 6. Through the setting of the brush 6, the debris attached to the screw rod 3 can be cleaned off to prevent the debris from entering the threaded groove inside the support plate 2;

[0030] When the brush 6 reaches the end of its service life, the staff can first pull the pulling bar 14, thereby driving the slot hole 10 to move at the same time. At this time, the pulling bar 14 can drive the moving block 11 to be stored inside the accommodating groove. At this time, the staff can pull the fixing bar 9, thereby the insertion rod 8 can be pulled out from the two groups of connecting blocks 7 and the inside of the support plate 2. When the two groups of insertion rods 8 are pulled out at the same time, the limitation of the four groups of rings 5 ​​can be released, so that the rings 5 ​​can be removed from the side wall of the support plate 2 and replaced with new rings 5. The above is the entire working principle of the utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
