Abstract

The utility model relates to a spiral spring end part chamfering machine which is a machine for chamfering. The utility model comprises a gyration conveying belt, a pressing plate and a pair of grinding wheels positioned on both sides of the conveying belt and driven by a motor to rotate, the spring needing processing is clamped between the conveying belt and the pressing plate, the utility model which is stressed by the double forces of the towing of the conveying belt and the pressure force of the pressing plate moves ahead while automatically rotating, and the chamfering is realized through the grinding and cutting of the fast rotating grinding wheels on both of the two sides of the conveying belt. When a grinding wheel mechanism is provided with a screw rod which makes the horizontal position and the height adjustable, the springs with different lengths and diameters can be ground and cut. The utility model has the advantages of automatic operation, increased production efficiency and safe operation, and can guarantee the production quality.

Description

The helical spring end chamfering machine

The utility model belongs to a kind of chamfering machinery.

The cylindrically coiled spring end-beveling mostly is manual operations at present, and not only production efficiency is low, and quality is bad, and very easily causes industrial injury, particularly points residual disconnected.

In view of above-mentioned, the purpose of this utility model provides a kind of automation, production efficiency height, safe and reliable, the helical spring end chamfering machine of ensuring the quality of products.

The helical spring end chamfering machine that the utility model provides, comprise the revolution conveyer belt, relative with the conveyer belt zone face, as to be used to insert and put processed spring pressing plate, the emery wheel mechanism that respectively has a grinding spring end chamfering to use in the conveyer belt both sides, this emery wheel mechanism contains frame, is positioned on the emery wheel on the frame and drives the motor that emery wheel rotates.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is the utility model structural principle schematic diagram;

Fig. 2 is a kind of example of the utility model.

With reference to Fig. 1, the utility model beveler comprises swinging conveyer belt 1, pressing plate 2, and the emery wheel mechanism that respectively has a grinding spring end chamfering to use in the conveyer belt both sides, this emery wheel mechanism contains frame 3, is positioned on the emery wheel 4 on the frame and drives the motor 5 that emery wheel rotates.During work, helical spring 10 moves in conveyer belt and pressing plate, because spring is subjected to the effect of the pressure dual power of conveyer belt traction and pressing plate, so it is operation forward on the one hand, on the other hand around self longitudinal axis rotation, under the atwirl wheel grinding in conveyer belt both sides, reach the purpose of spring end peripheral chamfer.

For adapting to the spring of grinding different length, different-diameter, preferably make the distance and the adjustable height of the relative conveyer belt of emery wheel, the distance that is shown in Figure 2, Height Adjustable emery wheel mechanism.In the illustrated example, frame 3 is can be around the V-arrangement frame of axle 6 swings, and emery wheel 4 is placed in respectively on V-arrangement frame two inclined-planes with motor 5, connects by belt.V-arrangement frame bottom is fixed on the planker 8 of band screw mandrel 7, it moves horizontally with the turnover of screw mandrel 7 screw threads, can change the distance of emery wheel 4 and conveyer belt 1, with the spring 10 that adapts to different length, other has a screw mandrel 9 to pass through V-arrangement frame inclined-plane, and be connected with frame by nut 11, the one end is fixed on the planker 8, and by the adjusting of screw mandrel 9, the V-arrangement frame is around axle 6 swings, can change the relative altitude of emery wheel 4 and conveyer belt 1, to adapt to the spring of different-diameter thereupon.

The utility model is operated with automatic instead of manual chamfering, and its production run is safe and reliable, increases substantially productivity ratio, and guarantees chamfer quality.
