Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a clamping tool for a precision CNC bending machine. Background Art

[0002] A press brake is a mechanical device used to bend sheet metal. It is widely used in manufacturing, construction, aerospace, automotive and other industries, mainly for making various metal components and frames.

[0003] The bending machines in the existing technology are unable to clamp workpieces of different sizes, resulting in the singleness of the products, being unable to adapt to the processing requirements of various products, and reducing the flexibility of production. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a clamping tool for a precision CNC bending machine.

[0005] The utility model is implemented by the following technical scheme: a clamping tool for a precision CNC bending machine, including a base, a support base fixedly connected to the right side of the base, a slide groove provided on the inner wall of the base, a slide groove 1 provided inside the base, a motor fixedly connected to the top of the support base, a threaded rod fixedly connected to the output end of the motor, the threaded rod rotatably connected to the inside of the base, the threaded rod threadably connected to a slider, the slider is slidably connected to the outer wall of the slide groove, the end of the threaded rod away from the motor is fixedly connected to slider 1, the slider 1 is rotatably connected to the outer wall of the slide groove, and a slot is provided on the top of the slider.

[0006] Through the above technical solution, the pipe is placed between the clamp and clamp 1 from the left side of the base. At this time, the motor drives the slider to move through the threaded rod, and a slide groove is opened inside the base. The sliding of the slider and the slide groove can make the clamp move stably, thereby reducing the wear between the slide groove and the slider and extending the service life. In order to ensure that the threaded rod does not deviate during the rotation process, a slide groove 1 is opened inside the base. The slide groove 1 is rotatably connected to the slider 1, and the slider 1 is fixedly connected to the threaded rod, so that the threaded rod can operate more efficiently. At the same time, the movement of the slider can drive the clamp to move. This not only fixes the workpiece, but also prevents the workpiece from sliding during operation, reduces the risk of accidents, and ensures the safety of operators. At the same time, workpieces of different sizes can be processed, which improves production diversity.

[0007] As a further improvement of the above solution, the inner wall of the base is fixedly connected to a fixing rod, the fixing rod is slidably connected to the inside of the slider, the bottom of the inner wall of the base is fixedly connected to an inclined guide block, and the outer wall of the fixing rod is contacted with a spring.

[0008] As a further improvement of the above solution, two fixing rods are provided, and the two fixing rods are symmetrically arranged around the center of the slider; two springs are provided, and the two springs are symmetrically arranged around the center of the slider.

[0009] As a further improvement of the above solution, the outer wall of the fixed rod is fixedly connected to the limiting block, the outer wall of the fixed rod is slidably connected to a clamping block, the inner wall of the clamping block is provided with a give way groove, the top contact of the slider is provided with a clamping claw, the inside of the clamping claw is provided with an avoidance groove, the clamping block passes through the inner wall of the clamping claw and is slidably connected, and the clamping block is slidably connected to the outer wall of the clamping groove.

[0010] As a further improvement of the above solution, two limit blocks are provided, and the two limit blocks are symmetrically arranged around the center of the base; two give way grooves are provided, and the two give way grooves are symmetrically arranged around the center of the slider.

[0011] Through the above technical solution, the motor drives the threaded rod to rotate, and the slider slides along the fixed rod. When the bottom of the clamping block contacts the inclined guide block, because the inclined guide block is an inclined surface, the clamping block will move upward. At this time, the clamping block slides inside the clamping jaw, thereby disengaging from the clamping slot. An avoidance groove is opened inside the clamping jaw to provide space for the clamping block to move upward. When the clamping block contacts the limit block, the clamping block is stuck and will not move. When the slider moves to the right again, the clamping block will be disengaged from the inside of the clamping jaw. At this time, the clamping jaw can be removed and replaced with other types of clamps. At the same time, different clamps can adapt to a variety of workpiece shapes and sizes, so that the production line can quickly switch between different products to meet diverse needs.

[0012] As a further improvement of the above solution, a support seat 1 is fixedly connected to the left side of the base, a slide groove 2 is opened inside the base, a motor 1 is fixedly connected to the top of the support seat 1, and a threaded rod 1 is fixedly connected to the output end of the motor 1.

[0013] As a further improvement of the above solution, the threaded rod 1 is rotatably connected to the inside of the base, the threaded rod 1 is threadedly connected to a clamping block 1, the clamping block 1 is slidably connected to the outer wall of the slide groove 2, the outer wall of the clamping block 1 is contacted with a clamping claw 1, and the clamping claw 1 is contacted and set on the top of the base.

[0014] Through the above technical solution, when the clamping jaw 1 also needs to be replaced, the motor 1 drives the clamping block 1 to slide along the slide groove 2 through the threaded rod 1, so that the clamping jaw 1 can be quickly released, which can reduce the equipment downtime, ensure the continuity of the production process, and improve the overall production efficiency.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model places the pipe between the clamping jaw and the first clamping jaw from the left side of the base. At this time, the motor drives the slider to move through the threaded rod, and a slide groove is provided inside the base. The sliding of the slider and the slide groove can make the clamping jaw move stably, thereby reducing the wear between the slide groove and the slider and extending the service life. In order to ensure that the threaded rod does not deviate during the rotation process, a slide groove is provided inside the base. The slide groove is rotatably connected to the first slider, and the first slider is fixedly connected to the threaded rod, so that the threaded rod can operate more efficiently. At the same time, the movement of the slider can drive the clamping jaw to move. This not only fixes the workpiece, but also prevents the workpiece from sliding during operation, reduces the risk of accidents, and ensures the safety of operators. At the same time, workpieces of different sizes can be processed, which improves production diversity.

[0017] The utility model drives the threaded rod to rotate through the motor, and at this time the slider slides along the fixed rod. When the bottom of the clamping block contacts the inclined guide block, because the inclined guide block is an inclined surface, the clamping block will move upward. At this time, the clamping block slides inside the clamping jaw, thereby disengaging from the clamping slot. An avoidance groove is provided inside the clamping jaw to provide space for the clamping block to move upward. When the clamping block contacts the limit block, the clamping block is stuck and will not move. When the slider moves to the right again, the clamping block will be disengaged from the inside of the clamping jaw. At this time, the clamping jaw can be removed and replaced with other types of clamps. At the same time, different clamps can adapt to a variety of workpiece shapes and sizes, so that the production line can quickly switch between different products to meet diverse needs.
