SU100245A1 - Grinding machine for plastic power bushings - Google Patents

Description

In the technique of grinding various products, machine tools are known that contain rotating grinding discs and a drive wheel for the products to be machined.

The proposed machine is also based on the use of grinding wheels and a driving wheel, but differs from those known for its design, designed for processing plastic inserts with grinding the end face and the edges of the sleeves in one turn of the driving wheel.

A distinctive feature of the proposed machine is. that the drive wheel is provided with radialio mounted mandrel mandrels for sleeves, 1 ”rotating during rotation of the circle, first with the circumferential working surface of the disk located above the circle for grinding the end of the sleeves, and then with the side working surface of the disk for grinding the edge of the sleeves. Grinding the edges of the sleeves for one revolution of the drive wheel is achieved by driving the wheel at an angle of 2-3 ° to the working surface of the disk for grinding the edges and carrying a fixed stop shield on its axis.

the surface of which has an elastic coating for rotation of the sleeves during grinding and a liner for oiling them.

FIG. 1 shows a side view of the machine with a cut along the axis of the drive circle; in fig. 2 gives an idea of the grinding process on the machine of the end of the sleeves, and FIG. Figure 3 shows the location on the drive wheel of the elastic coating machine and the oil liner.

The working parts of the machine are driving circle 1 and grinding wheels 2 and 3; The disk 2 serves to grind the end of the sleeves 4, and the disk 3 serves to grind the edges of these / box sleeves. In this case, the leading circle is located to the working surface of the disk 3 at an angle of 2-3 ° in order to gradually process the edge of the screw with disk 3 while slowly turning the circle 1 in direction of arrow 5.

To hold the sleeves 4 on the circumferential surface of the drive circle 1, the mandrels 6 and the clamp 7 serve, and for the sleeves to rotate during the grinding of their edges, there is an elastic coating S on the support shield 9. On the same ngnt there is oil on the wafer W, designed for

rotation of the finished sleeves with simultaneous oiling.

The grinding process of a plastic-molded plastic bushes on a machine begins with the processing of their end face with a disk 2. As the circle spins its rotation / along arrow 5, the edge of the second grinding disk 3 undergoes the edge of the sleeve, which falls off from the end 6 in finished form.

PREAMETE OF THE INVENTION

1. A machine for grinding plastic power inserts with rotating grinding discs and a driving wheel, which is different from the fact that, in order to ensure the grinding of the edges and the end of the sleeves on it, the driving circle of the machine is equipped with radna. mandrels for sleeves that interact with the rotation of a circle first with the circumferential working surface of a disk located above the circle for grinding the ends of the sleeves, and then with a side working surface of the disk for grinding the edges of the sleeves.

2. The shape of the machine squeeze on n. characterized in that, in order to carry out the grinding of the edge of the sleeves in one revolution of the leading circle, the nestle is located at an angle of 2-3 ° to the working surface of the disk for grinding the edges, and the fixed stop shield has e.gastik coatings to rotate the shoes in the process their grinding and gadodusku for their oiling.
