Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamping fixture with adjustable angle. Background Art

[0002] There are three common methods for processing inclined surfaces on existing milling machines: 1. Adjust the machine head to the required degree for processing; 2. Use an inclined tool for processing; 3. Clamp the workpiece to the required degree for processing; In order to meet the processing requirements, an inclined milling cutter and the workpiece are generally clamped to the required angle for processing. When an inclined milling cutter is used, it is clamped with a traditional flat-nose pliers, which is inefficient and has large vibrations that affect the overall accuracy of the machine tool. When an inclined vise is used to clamp the workpiece to the required angle, the vise itself is heavy and generally requires two people to move it. It also needs to be calibrated when getting on and off the machine, which is troublesome to use and thus inefficient. In addition, there are few clamping surfaces, and the processing position is too high, which can easily cause the tool to loosen. Summary of the invention

[0017] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] Please see attached Figure 1As shown: An angle-adjustable clamping fixture includes a connecting base 1, an adjusting drive unit 2, and a clamping platform carrier 3. The connecting base 1 can be directly docked and installed on the processing machine through fasteners, and is used to support the installation of the adjusting drive unit 2 and the clamping platform carrier 3; the adjusting drive unit 2 can be rotatably set on the connecting base 1, and is used to provide a driving force for the angle adjustment of the clamping platform carrier 3; the clamping platform carrier 3 can be swingably set on the connecting base 1; the adjusting drive unit 2 can drive the clamping platform carrier 3 to swing and adjust the processing angle. The utility model adjusts the relative position of the clamping platform carrier 3 by adjusting the drive unit 2, so that the processing position always remains vertically set. It has a reasonable structural design, is easy to use and flexible, solves the problem of large angle processing troubles, reduces the labor intensity of the operator, and improves work efficiency. The adjusting drive unit 2 and the clamping platform carrier 3 will be introduced in detail below.

[0019] On the basis of the above-mentioned embodiment, the adjustment drive unit 2 includes a rotating shaft 21 rotatably arranged on the connecting base 1; one end of the rotating shaft 21 is detachably connected with a lifting block 22, and the lifting block 22 is in surface contact with the clamping platform carrier 3, and the other end of the rotating shaft 21 is connected with a wheel driving assembly 23. When the angle needs to be adjusted, just manually swing the wheel driving assembly 23 to rotate it, which will drive the crescent-shaped lifting block 22 to rotate, and then drive the angle of the clamping platform carrier 3. When the adjustment is in place, release the wheel driving assembly 23, and the wheel driving assembly 23 will self-lock under the gravity of the clamping platform carrier 3. It is easy to use and flexible, and solves the problem of troublesome processing of large angles. The wheel driving assembly 23 is a prior art and is well known to those skilled in the art, and will not be described here.

[0020] Based on the above embodiment, the clamping platform carrier 3 includes a swing shaft assembly 31 fixedly mounted on one end of the connecting base 1, which is used to provide slewing support for the rotation of the entire clamping platform carrier 3; a loading platform 32 is fixedly mounted on the swing shaft assembly 31, which is used to clamp the parts to be processed; a positioning assembly 33 is detachably inserted on the loading platform 32, which is used to position the parts; a clamping member 34 is detachably mounted on the loading platform 32, which is used to tightly fix the zero point on the loading platform 32 to prevent tipping or movement during the processing process.

[0021] Based on the above embodiment, an inner T-shaped mounting groove is provided on the loading platform 32 near the end of the swing shaft assembly 31; an array of penetrating locking holes are provided on the swing shaft assembly 31; and a supporting locking portion protruding outward is provided on one side of the loading platform 32.

[0022] Based on the above embodiment, the positioning assembly 33 includes a positioning base that is detachably inserted into the T-shaped mounting groove, and a positioning block can be movably set on the positioning base.

[0023] Based on the above embodiment, a locking screw 11 is swingably provided on the connecting base 1 .

[0024] By adopting the above technical solution, in the utility model, the clamping platform 3 on the connecting base 1 can be adjusted adaptively according to the size of different processing angles. Specifically, when it is necessary to adjust the angle between the connecting base 1 and the bottom surface of the clamping platform 3 to 45 degrees. Manually bend the adjustment drive part 2 to rotate, at this time the lifting block 22 starts to rotate to swing the loading platform 32 to an angle of 45 degrees, and then release it, and then lock the locking screw 11 on the connecting base 1, so that the entire is in a triangular stable support state. During processing, the workpiece to be processed is placed on the loading platform 32, and after being positioned by the positioning assembly 33, it is fixed to the loading platform 32 by the clamping member 34. In this way, it can be directly placed on the milling machine for processing.
