Description

Technical Field

[0001] The utility model relates to the technical field of cutting fixtures, in particular to a mechanical processing cutting fixture. Background Art

[0002] A cutting fixture is a device used to clamp a workpiece for cutting during machining. It mainly serves to fix and stabilize the workpiece, ensuring that the workpiece maintains a fixed position and posture during cutting, and preventing the workpiece from moving during the cutting process, thereby ensuring the accuracy and safety of the cutting process. There are many types of cutting fixtures, and flat-nose pliers are one of the most frequently used fixtures, which play an important role in improving machining efficiency and quality.

[0003] At present, the existing flat-nose pliers are mainly composed of a pliers base, a screw, an movable pliers and a fixed pliers. When it is necessary to fix the workpiece, the staff can rotate the screw to push the movable pliers body and the fixed pliers closer to achieve clamping and fixing of the workpiece. Although the lateral position of the movable pliers can be adjusted by the screw, the position of the fixed pliers cannot be moved, which makes the clamping range of the flat-nose pliers relatively limited, that is, it is difficult to meet the clamping needs of some longer workpieces. For this reason, we propose a machining cutting fixture to solve the above problem. Utility Model Content

[0022] 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 the embodiments.

[0023] Reference Figure 1-5 A machining cutting fixture comprises a clamp seat 1, a screw rod 2 is inserted into the inside of the clamp seat 1, and the end of the screw rod 2 is connected to the clamping clamp 3 through a bearing. There are two groups of clamping clamps 3, and the side of the other group of clamping clamps 3 is connected to a connecting plate 4. A rectangular groove adapted to the connecting plate 4 is opened above the clamp seat 1, and a connecting rod 5 is laterally connected to the side of the clamping clamp 3. An insertion groove adapted to the connecting rod 5 is opened inside the clamp seat 1, and a limiting mechanism is provided at the bottom end of the clamp seat 1.

[0024] Further, refer to Figure 3 It can be seen that the limiting mechanism includes a slot hole 6, which is opened at the bottom end of the clamp seat 1. A rectangular plate 7 is inserted into the inside of the slot hole 6, and the side of the rectangular plate 7 is connected to the limiting rod 8. The lower sides of the two groups of rectangular plates 7 are vertically connected with a pull rod 10. The bottom end of the clamp seat 1 is provided with a push-pull groove that is compatible with the pull rod 10, and the outer wall of the connecting rod 5 is provided with positioning grooves that are equidistantly spaced laterally that are compatible with the limiting rod 8. When in use, the opening of the push-pull groove can facilitate the staff to move the rectangular plate 7 laterally, so that the limiting rod 8 can be pulled out from the inside of the connecting rod 5, or embedded in the positioning groove opened inside the connecting rod 5.

[0025] Further, refer to Figure 1 and Figure 3 It can be seen that two groups of connecting rods 5 are provided, and the two groups of connecting rods 5 are symmetrically distributed about the central axis of the clamping clamp 3. By setting the two groups of connecting rods 5, the fixing effect of the left clamping clamp 3 can be effectively improved.

[0026] Further, refer to Figure 3 It can be seen that a connecting spring 9 is provided inside the slot 6, and the two ends of the connecting spring 9 are fixedly connected to the side of the rectangular plate 7. Through the elastic characteristics of the connecting spring 9 itself, the tightness of the limit rod 8 when inserted into the slot of the connecting rod 5 can be effectively guaranteed.

[0027] Further, refer to Figure 1 and Figure 2It can be seen that a rubber plate 11 is provided on the side where the two sets of clamping pliers 3 are close to each other, and the outer wall of the rubber plate 11 is provided with anti-slip grooves 15. When in use, the mutual cooperation between the rubber plate 11 and the anti-slip grooves 15 can effectively improve the limiting effect of the workpiece and effectively prevent the outer wall of the workpiece from being crushed.

[0028] Further, refer to Figure 4 It can be seen that the lower side of the rubber sheet 11 is vertically connected to an embedding plate 12, and the interior of the clamping pliers 3 is provided with an embedding groove 13 that is compatible with the embedding plate 12. When in use, the embedding plate 12 and the embedding groove 13 cooperate with each other, which makes it easy for the staff to quickly remove the deformed rubber sheet 11.

[0029] Further, refer to Figure 4 It can be seen that the outer side of the embedded plate 12 is equidistantly connected with rubber strips 14, and the outer side of the rubber strips 14 is tightly fitted with the inner wall of the embedded groove 13. When in use, the rubber strips 14 set by multiple groups of rubber materials can effectively ensure that the embedded groove 13 is inserted tightly into the embedded plate 12, thereby ensuring the reliability of the rubber plate 11 when in use.

[0030] When the workpiece is longer than the working length, the staff can first pull the two sets of pull rods 10 to drive the two sets of rectangular plates 7 and the limit rod 8 to move at the same time, so that the limit rod 8 is pulled out from the inside of the connecting rod 5. At this time, the staff can pull the left clamping clamp 3 laterally, so that the connecting plate 4 and the connecting rod 5 connected to the side thereof move simultaneously to adjust the spacing between the two sets of clamping clamps 3. When the spacing between the two sets of clamping clamps 3 is adjusted to a suitable position, the staff can stop pulling the pull rod 10, so that the two sets of limit rods 8 are inserted into the corresponding connecting rod 5 in turn through the elastic force of the connecting spring 9 to fix the position of the left clamping clamp 3. Since the spacing between the clamping clamps 3 is larger at this time, it can meet the fixing requirements of some longer workpieces. The above is the entire working principle of the present invention.

[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 on.

[0032] The above embodiments are preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
