Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically to a material fixing fixture for machining. Background Technology

[0002] In machining processes, to ensure machining accuracy and operational safety, it is necessary to securely fix the workpiece using fixtures. Currently, most commonly used material fixing fixtures are traditional bench vises, which use a lead screw to drive the jaws to achieve clamping action. While these can meet basic fixing requirements, they have the following shortcomings: First, the flexibility of adjusting the fixing position is poor, and the positioning accuracy is low after the vise is moved as a whole, making it difficult to quickly adapt to the needs of different machining positions; second, the locking mechanism is cumbersome to operate, requiring multiple adjustments to the locking fixation after clamping, and it is prone to loosening during long-term machining.

[0003] To address the aforementioned issues, there is an urgent need to design a flexible, secure, and easy-to-operate material fixing fixture for machining, in order to improve the efficiency and quality of machining. Utility Model Content

[0004] This utility model aims to solve the above-mentioned technical problems by providing a material fixing fixture for machining.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A material fixing fixture for machining includes a tooling platform and a bench vise that can slide on the tooling platform, wherein a fixing rod is fixedly connected to the bench vise by bolts;

[0007] A fixed column is installed on the tooling platform. A movable first clamping arm and a second clamping arm are installed on the outside of the fixed column. The first clamping arm and the second clamping arm are semi-circular structures. One end of the first clamping arm and the second clamping arm are hinged and can be fitted onto the outside of the fixed column. The fixing rod passes through the first clamping arm.

[0008] A locking device is installed on one side of the second clamping arm for clamping the first clamping arm and the second clamping arm to the fixing post and the fixing rod.

[0009] Furthermore, a through hole is provided on the first clamping arm to cooperate with the fixing rod. The through hole enables precise cooperation between the fixing rod and the first clamping arm, ensuring the positioning accuracy after the vise moves.

[0010] Furthermore, a groove is provided on the side of the first clamping arm near the fixing post, and the groove is connected to the through hole. The groove is designed to provide installation space for the clamping block, while enhancing the fit between the fixing rod and the first clamping arm.

[0011] Furthermore, a clamping block is installed in the groove between the fixed post and the fixed rod. Both sides of the clamping block are arc-shaped structures that can fit together perfectly with the outer circular surfaces of the fixed post and the fixed rod, thereby improving clamping stability.

[0012] Furthermore, the locking device includes an adjusting groove on the second clamping arm and a rotating block that rotates within the adjusting groove. The rotating block has a rotatable connecting post offset from its axis. The rotating block has a through hole for use with the connecting post. A connecting groove is formed on one side of the rotating block, connecting to the first through hole. The first clamping arm has a mounting hole for installing a bolt, and the second clamping arm has a through hole for the bolt to pass through. The bolt passes through the second through hole and the connecting groove and is threaded to the side of the connecting post. By rotating the rotating block using the offset connecting post, the position of the connecting post can be adjusted, thereby causing the first and second clamping arms to clamp or loosen via the bolt.

[0013] Furthermore, a limiting groove is formed on the second clamping arm and the limiting groove is connected to the adjusting groove. A limiting block is installed in the limiting groove, and a guide rod is installed on one side of the limiting block, passing through the rotating block. A spring is installed on the outside of the guide rod, between the rotating block and the limiting block. The elastic force of the spring can provide a preload force to the rotating block, preventing the rotating block from loosening during processing and improving the locking reliability.

[0014] Furthermore, the rotating block has a moving hole that moves in conjunction with the guide rod. The moving hole guides the movement of the guide rod and ensures the stability of the rotating block during rotation.

[0015] With the above structure, this utility model has the following advantages:

[0016] The vise can slide on the tooling platform. With the through engagement of the fixing rod and the first clamping arm, the vise position can be quickly adjusted and accurately positioned to meet the needs of different machining positions. The first and second clamping arms are hinged and fitted on the outside of the fixing post. The angle of the clamping arms can be flexibly adjusted according to the position of the fixing rod, further improving the adjustability.

[0017] The first and second clamping arms are fitted with a semi-circular structure, and clamping blocks with arc-shaped sides are set in the groove, so that the fixed column and the fixed rod can be tightly fitted through the clamping blocks to form a multi-point clamping structure, which effectively prevents the material from shaking during processing. The design of the off-axis connecting column in the locking device can achieve precise adjustment of the clamping force by rotating the rotating block, thereby improving the clamping reliability.

[0018] The locking device uses bolts to connect with the off-axis connecting column, and the clamping and loosening actions can be completed simply by rotating the rotating block, making it easy to operate. At the same time, the spring in the limit groove provides a continuous preload force to the rotating block through the guide rod, which prevents the locking from loosening during long-term processing and improves the safety of equipment use.

[0019] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

The first clamping arm 5 and the second clamping arm 6 are semi-circular structures. When combined, they can form a complete circular clamping structure. One end of the first clamping arm 5 and the second clamping arm 6 are hinged and can be fitted onto the outside of the fixed column 4 to realize the flexible rotation of the clamping arm. A through hole 501 is opened on the first clamping arm 5 to cooperate with the fixed rod 3. The fixed rod 3 passes through the through hole 501 of the first clamping arm 5 to realize the linkage positioning of the vise 2 and the clamping arm.

[0029] In specific use, this utility model, such as Figure 1 and Figure 2 As shown, a groove 502 is provided on the side of the first clamping arm 5 near the fixed post 4 and the groove 502 is connected to the through hole 501. A clamping block 8 is installed in the groove 502 and between the fixed post 4 and the fixed rod 3. Both sides of the clamping block 8 are arc-shaped structures for cooperation. The curvature of the arc-shaped structure is consistent with the outer curvature of the fixed post 4 and the fixed rod 3, respectively, to ensure tight fit.

[0030] Specifically, a locking device 7 is installed on one side of the second clamping arm 6 for clamping the fixing post 4 and the fixing rod 3 between the first clamping arm 5 and the second clamping arm 6. The locking device 7 includes an adjusting groove 705 opened on the second clamping arm 6 and a rotating block 701 that rotates within the adjusting groove 705. A rotatable connecting post 702 is off-axis arranged on the rotating block 701. The connecting post 702 and the rotating block 701 are rotatably connected by a bearing. A through hole 704 is opened on the rotating block 701 to cooperate with the connecting post 702.

Hole 9; a through hole 2 is provided on the second clamping arm 6 for a bolt to pass through; the bolt passes through the through hole 2 and is threadedly connected to the side of the connecting column 702 via the connecting groove 703; a limiting groove 14 is provided on the second clamping arm 6 and the limiting groove 14 is connected to the adjusting groove 705; a limiting block 10 is slidably installed in the limiting groove 14; a guide rod 11 is welded to one side of the limiting block 10 and passes through the rotating block 701; a moving hole 13 is provided on the rotating block 701 to move in conjunction with the guide rod 11; a spring 12 is fitted on the outside of the guide rod 11 and between the rotating block 701 and the limiting block 10; the spring 12 is always in a compressed state to provide continuous preload force for the rotating block 701.

[0031] The working principle of this utility model:

[0032] In use, firstly, according to the size of the material being processed and the processing position requirements, push the vise 2 to slide on the tooling platform 1 to a suitable position. At this time, the fixing rod 3 moves synchronously and passes through the through hole 501 of the first clamping arm 5. Next, place the clamping block 8 into the groove 502 of the first clamping arm 5, so that both sides of the clamping block 8 are in contact with the fixing post 4 and the fixing rod 3 respectively. Then, rotate the rotating block 701. Due to the off-axis setting of the connecting post 702, the rotating block 701 drives the connecting post 702 to move closer to the first clamping arm 5 during rotation. This, in turn, pulls the first clamping arm 5 around the hinge point through the bolt, causing the first clamping arm 5 to rotate. Arm 5 and the second clamping arm 6 gradually clamp the fixing column 4 and the fixing rod 3 until the clamping block 8 is tightly attached to the surfaces of both, completing the clamping action; the guide rod 11 slides in the moving hole 13, the limiting block 10 is placed in the limiting groove 14, the spring 12 further exerts a reverse force on the rotating block 701 to prevent the rotating block 701 from loosening; after processing, with the guide rod 11 sliding in the moving hole 13, the limiting block 10 disengages from the limiting groove 14, the rotating block 701 rotates in the opposite direction, the connecting column 702 drives the bolt to loosen, the first clamping arm 5 and the second clamping arm 6 separate, and the vise 2 can be pushed to adjust the position or remove the material.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
