Description
Technical Field
The utility model relates to the technical field of clamps, in particular to a clamp special for machining a large C angle of a workpiece.
Background
In the processing of the mould parts, a large C angle inclined plane needs to be processed, for example, the large C angle at the bottom of a mould core backing plate is processed, and in order to reduce the resource waste of numerical control equipment, a common milling machine is used for processing without special requirements. While three methods are commonly used for milling inclined surfaces: 1. machining the machine head into a required degree; 2. machining by using a slope cutter; 3. clamping a workpiece into a required degree for machining; in order to meet the machining requirement, a gradient milling cutter and a workpiece are generally adopted to clamp the workpiece to a required angle for machining. When the inclination milling cutter is adopted, the traditional flat tongs are used for clamping, so that the efficiency is low, and the vibration greatly affects the whole precision of the machine tool. When the inclination vice is adopted for clamping and processing, the weight of the vice is larger, and the vice can be moved by two people, and the upper machine and the lower machine are required to be corrected, so that the efficiency is low, the clamping surface is less, and the elastic knife is easy to loosen when the processing position is too high. Therefore, how to design a fixture suitable for a milling machine, can effectively process a plurality of large C-angle workpieces, is convenient and flexible to use, and becomes the direction of thinking.

The fixture overcomes the defects of the prior art, is reasonable in structural design and convenient and flexible to use, solves the problem of difficulty in machining a large inclined plane of the milling machine, and improves the working efficiency.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
a fixture special for machining a large C angle of a workpiece comprises a base with an inclined surface at the side edge, a clamping base plate fixedly installed on the inclined surface, a positioning stop block arranged at the bottom of the clamping base plate and at least one pressing block arranged on the clamping base plate.
Preferably, the pressing block is of an L-shaped structure, the pressing block is provided with an upright section which is abutted with the clamping backing plate and can be arranged in an adjustable mode and a pressing section which is integrally formed with the upright section, a strip-shaped hole is formed in the pressing section, and the fastener penetrates through the strip-shaped hole and positions the workpiece on the clamping backing plate.
Preferably, the pressing blocks are four and are respectively positioned at four corners of the clamping backing plate.
Preferably, the top surface of the positioning stop block is higher than the top surface of the clamping backing plate.
Preferably, two positioning stoppers are provided.
The utility model has the beneficial effects that:
the utility model has reasonable structural design, convenient and flexible use, solves the problem of troublesome processing of a large C angle, reduces the labor intensity of operators and improves the working efficiency.

Description of the embodiments
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1-4, a fixture specially used for processing a large C angle of a workpiece comprises a base 1 with an inclined surface 11 at the side edge, a clamping backing plate 2 fixedly arranged on the inclined surface 11, a positioning stop block 3 arranged at the bottom of the clamping backing plate 2 and at least one pressing block 4 arranged on the clamping backing plate 2; the pressing block 4 is of an L-shaped structure, the pressing block 4 is provided with an upright section 41 which is abutted with the clamping backing plate 2 and can be arranged in an adjustable mode, and a pressing section 42 which is integrally formed with the upright section 41, a strip-shaped hole 43 is formed in the pressing section 42, and a fastener penetrates through the strip-shaped hole 43 and positions a workpiece on the clamping backing plate 2; the pressing blocks 4 are provided with four, and are respectively positioned at four corners of the clamping backing plate 2; the top surface of the positioning stop block 3 is higher than the top surface of the clamping backing plate 2; the positioning block 3 is provided with two.
By adopting the technical scheme, in the utility model, the inclined plane 11 on the base 1 can be adjusted adaptively according to the large C angle processed at different angles. Specifically, the angle between the inclined surface 11 and the bottom surface of the base 1 may be 45 degrees. The clamping backing plate 2 can be fixed on the inclined plane 11 of the base 1 through pins and screws. The positioning stop block 3 is fixed at the bottom of the clamping backing plate 2 through pins and screws, and plays a role in positioning.
