Problems solved by technology

[0004] 1. It is more suitable for parts with standard shapes. It is difficult to clamp parts with special shapes such as crankshafts. Only special fixtures can be designed. However, there are many types of parts that need to be processed during processing, so it is necessary to design a large number of special fixtures, which not only wastes time. , also wastes space
[0005] 2. The fixtures in the prior art are not adjustable and have a small scope of application, so they are not suitable for processing parts of various sizes

Abstract

The invention relates to a machine tool clamp, in particular to an adjustable clamp for a numerically-controlled machine tool. The adjustable clamp comprises lifting adjusting devices, workpiece clamping devices, a workpiece supporting device, a fixed base, hoisting frames and supporting rods. The workpiece clamping devices are mounted on the lifting adjusting devices through keys, and the two lifting adjusting devices are mounted on the workpiece supporting device. The workpiece supporting device is fixedly mounted above the fixed base, and the hoisting frames are fixedly mounted on the fixedbase. The supporting rods are fixedly mounted on the workpieces supporting device, and the other ends of the supporting rods are fixedly mounted on the fixed base. The number of the supporting rods is four. According to the adjustable clamp, the height of the two ends and the distance between the two ends can be independently adjusted, and the device can adapt to parts of multiple sizes; the device is provided with a jacking device, and it can be avoided that the parts bear force to deform when machined, and consequently machining errors are caused; and due to the fact that the device is provided with the hoisting frames, a crane can be prevented from damaging the device in the device is hoisted.

Description

Technical field [0001] The invention relates to a fixture for machine tools, more specifically an adjustable fixture for numerical control machine tools. Background technique [0002] The machine tool is inseparable from the auxiliary device in the additional processing. The fixture is one of the more important auxiliary devices. The tight and stable type of the fixture directly affects the processing accuracy. During the processing, there are often some special shapes. Parts, crankshafts can be said to be a representative one. For clamping parts with special shapes, the prior art has many shortcomings. The shortcomings of the prior art will be described below. [0003] The disadvantages of the existing technology are: [0004] 1. It is more suitable for parts with standard shapes. It is more difficult to clamp special-shaped parts such as crankshafts. Only special fixtures can be designed. However, there are often many types of parts that need to be processed in processing, so it i...
