Description

Wire cutting fixture

Technical field:

The invention relates to a tooling fixture, in particular to a wire cutting fixture.

Background technique:

Among the various fixtures used in the current CNC wire cutting process, the adaptability of the fixtures to parts is generally poor, and often some irregular parts cannot be clamped by fixtures with a high degree of automation, and thinner and longer parts are processed by wire cutting. The workpiece is easily deformed under the clamping pressure of the fixture; in the online cutting and slicing process, the traditional method is to fix the blank on the machine with a pressure plate by the machine operator, and then use a dial gauge to correct the straightness and levelness. And this process will take a lot of time, which affects the processing efficiency to a large extent; in this way, in actual processing, it will lead to long workpiece correction time, long machine standby time, and low production efficiency; with the continuous development and growth of modern industry , the precision requirements of its industrial products are getting higher and higher, and the cost requirements are getting lower and lower. The original clamping fixtures lag behind the requirements of modern industrial development.

Invention content:

The object of the present invention is to provide a wire-cutting fixture with high working efficiency, which can prevent deformation of the workpiece when processing thinner and longer workpieces, and can adjust the width of the clamping groove to be suitable for workpieces of different thicknesses.

In order to achieve the above object, the technical scheme adopted in the present invention is:

Wire cutting fixture, it includes a base, a pressure plate set on the top of the base, the pressure plate is locked on the base by adjusting screws, the top of the front end of the base and the bottom of the front end of the pressure plate are respectively provided with corresponding transverse notches, the base and the pressure plate The notches are combined to form a clamping groove for clamping the workpiece; the bottom of the pressure plate is provided with a vertical guide rail, and the base is provided with a slide groove matched with the guide rail, and the guide rail is slidably connected in the slide groove; the guide rail is T-shaped block, the chute is a T-shaped groove; the guide rail is fixed on the pressure plate by fixing screws; the base is provided with screw holes for fixing on the machine table.

The base is provided with positioning pins, the pressing plate is provided with pin holes, and the bottom of the positioning pins passes through the pin holes of the pressing plate to connect with the base.

The beneficial effects of the present invention are:

The present invention includes a base and a pressing plate arranged on the top of the base. The pressing plate is locked on the base by adjusting screws. It is combined into a clamping groove for clamping the workpiece. When in use, the distance between the pressure plate and the base is adjusted by adjusting the screw, thereby adjusting the width of the clamping groove. The clamping groove can be adjusted to be suitable for workpieces of different thicknesses, and the workpiece is placed on the In the clamping groove, tighten the adjusting screw to clamp the workpiece, that is, complete the clamping process. The work is clamped in the clamping groove of this elongated structure, which can prevent the deformation of thinner and longer workpieces during processing, and is easy to operate. It can be processed in batches, saving calibration time and improving work efficiency.

Description of drawings:

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the structural representation of pressing plate of the present invention;

Fig. 3 is a structural schematic diagram of the base of the present invention.

Detailed ways:

The present invention will be further described below in conjunction with the accompanying drawings. As shown in FIGS. , the adjustment screw 10 is used to lock the workpiece, the top of the front end of the base 1 and the bottom of the front end of the pressure plate 2 are respectively provided with corresponding horizontal strip-shaped notches 3, and the notches 3 of the base 1 and the pressure plate 2 are close together Combined into a clamping groove for clamping workpieces.

The bottom of the pressure plate 2 is provided with a vertical guide rail 5, and the base 1 is provided with a chute 4 matching with the guide rail 5. The guide rail 5 is slidably connected in the chute 4, and the pressure plate 2 can slide vertically along the chute 4. It is convenient to adjust the distance between the pressure plate 2 and the base 1, the guide rail 5 is a T-shaped block, the chute 4 is a T-shaped groove, and the guide rail 5 is fixed on the pressure plate 2 by fixing screws 6 . Certainly, it is also possible that the guide rail 5 is arranged on the base 1 , and the slide groove 4 is arranged on the pressing plate 2 .

The base 1 is provided with screw holes 7 for fixing on the machine platform. The base 1 is provided with a positioning pin 8, which is used for horizontal positioning of the fixture, and the pressing plate 2 is provided with a pin hole 9, and the bottom of the positioning pin 8 passes through the pin hole 9 of the pressing plate 2 and is connected with the base 1.

When in use, adjust the distance between the pressure plate 2 and the base 1 by adjusting the screw 10, thereby adjusting the width of the clamping groove. The clamping groove can be adjusted to be suitable for workpieces of different thicknesses. Place the workpiece in the clamping groove and tighten the adjusting screw 10 Clamp the workpiece, that is, complete the fixture process. The work is clamped in the clamping groove of this elongated structure, which can prevent the deformation of thinner and longer workpieces during processing, and is easy to operate, can be processed in batches, and saves correction time. Improve work efficiency.
