Description

J

The invention relates to the field of surface treatment of parts and can be used in engineering, foundry and other industries.

The limestone of the device for the surface: -treatment of parts, containing a drum mounted on sharshny, associated with the drive of the movement of the drum supports, made in the form of rotating; Shih VI mounted pivotally cranks p .. Yel 1United- improvement of the design of the device due to a decrease in the number of bouncing in the ball 1 | Irov.

This is achieved by the fact that the axes of rotation of the crank bearings are located under the angle equal to the angle of inclination of the geometrical axes of the hinge of the drum, and the distance between the geometrical axes of the crank and drum balls is proportional to the angles of inclination of their geometrical axes.

Fng, 1 schematically shows the proposed device; in fig. 2 crank.

The tumbling device comprises a drum 1 pivotally mounted on two supports — spatial cranks, 2 and 3, one. From which it is connected with the drive, LETTING, we HELP TO GET to get different speeds of rotation of the drum, for example, by a multi-time transmission (not shown). Crank 3 freely connects with stash 4. The axis of rotation of crank 2 is located to the axis of rotation of L – B of crank 3 at an angle cL (D0 d –150 °) and is located at a certain distance of 6 from it. The relative position of the geometrical axes of the drum 1 the same as the axle axles of the cranks. The shortest distances between the crankshaft crankshaft axes and

In addition to Toix), the geometric axis of the tree is ala in itowittrak each) from the curvature of the scrapper | otsg at an angle of about 6 - 28.

Depending on the type of parts being used, you can choose the right part of the drum and the processing time, as well as select the optimal size of the drum, which has a replaceable internal capacity.

The device works as follows js. . ,

From the factory, the damage is transmitted to anyone (from cranks, for example, crank 2, which through drum 1 is transmitted and transmitted by wheel 3, in this KpttBoumn 2, it rises in a plane located under the plane to the plane 3, with constant crankshaft 3). angular velocity, and crank the 3rd variable. Drum 1 with parts receives a complex 5 spatial non-uniform motion, increasing the intensity of processing the selected, -.,

The & v (o6 device doesn’t significantly reduce the manufacturing process of the plant, increase the efficiency of product processing, tests carried out on the pilot plant, showed that the processing time is reduced by 3.5 times compared with the tumbling in the drum with uniform rotation.
