Abstract
The invention relates to a machine accessory equipment, further relates to a dish-shaped parts rotary end surface supporting roller differential mechanism, aiming at solving the technical defect of the serious abrasion of the roller surface. The dish-shaped part rotary end surface supporting roller differential mechanism arranged below the dish-shaped part end surface plays a supporting role, and the number of the differential mechanisms is at least three. The roller mechanism comprises a base plate, a bracket fixedly connected with the base plate and a fixed shaft put up in the middle of the bracket, and the fixed shaft is fixedly connected with the bracket. Rolling bearings are mounted on a fixed bearing side by side, and the number thereof is at least two. Spacer bushes are arranged between the two end surfaces of the rolling bearing and the bracket. Compared with the prior art, the invention has the advantages of greatly reducing the linear speed difference of the workpiece and the roller surface and lowering the sliding friction of the roller and the workpiece surface, thus reducing the surface abrasion of the roller, due to the design of the dish-shaped parts rotary end surface supporting roller differential mechanism.
Description
Technical field
The present invention relates to a kind of machine tool auxiliary equipment, further relate to a kind of disk-like accessory rotary end surface supporting dragging roller box of tricks.
Background technology
As shown in Figure 1, in the prior art, when the large disc type part horizontally rotates, because the lower surface dragging roller is whole cylindrical running roller, in rotary course, the linear velocity difference of dragging roller outer surface, periphery produces relative sliding motion with the workpiece contact-making surface, make that the dragging roller surface abrasion is serious, robust motion is poor, and driving moment is big.
The linear velocity that workpiece rotates its end face each point is 2 π Rn (n=rotating speed, R=workpiece radius), and promptly each spot speed is directly proportional with R, and as shown in Figure 2, the Workpiece internal-external circle semidiameter is 300mm, and promptly speed difference is 600 π n.
Summary of the invention
It is serious to the objective of the invention is to solve the dragging roller surface abrasion, and robust motion is poor, the technological deficiency that driving moment is big.The present invention is achieved by the following scheme.
Disk-like accessory rotary end surface supporting mechanism comprises: drive the main drive wheel of disk-like accessory rotation, by with the frictional force drives disk-like accessory rotation of the outer circumference surface of disk-like accessory; Driven pulley plays a part the disk-like accessory radial location; Be positioned at passive disk-like accessory rotary end surface supporting dragging roller box of tricks under the disk like part end face, the quantity of box of tricks is at least 3; Described dragging roller mechanism comprises: base plate, and the support of fixedlying connected with base plate, the fixed axis of frame in the middle of support, fixed axis is fixedlyed connected with support; The rolling bearing of on rigid bearing, laying side by side, the quantity of rolling bearing is at least 2; Lay respectively at the spacer between two ends rolling bearing end face and the support.
The axial section shape of described rolling bearing is preferably trapezoidal, with the disk-like accessory contact jaw be trapezoidal minor face.
The present invention is with respect to the advantage of prior art:
(1) design of disk-like accessory rotary end surface supporting dragging roller box of tricks greatly reduces the linear differential on workpiece and dragging roller surface, has reduced the force of sliding friction of dragging roller and surface of the work, thereby has reduced the surface abrasion of dragging roller.
(2) sliding friction reduce, increased the stationarity of workpiece rotary course.
(3) reducing of force of sliding friction reduced driving moment, saved the energy.
