Abstract
The utility model discloses a roller device for on channelling machine, being equipped with the mount pad that the through -hole was described to the step including the middle part, wearing to be equipped with the roller bearing in the mount pad, the one end that the roller bearing exposes the mount pad is equipped with the colyliform pressure head, and the roller bearing is organized through the two sets of bearings in front and back and is rotated to wear to establish in the base, and fore bearing group includes to be followed near one section two cylindrical roller bearings and deep groove ball bearing who begins to set gradually of colyliform pressure head, and the rear bearing is organized to kingpin and thrust ball combination bearing, and base backend is equipped with the back shroud, and the base front end is equipped with the front shroud. This roller device slot rolling machining precision is high.
Description
Technical field
The utility model relates to a kind of tubular object extruding equipment, relates in particular to a kind of roller devices on channelling machine.
Background technology
Channelling machine is when using ditch trough connection as conduit coupling, pipe is given to the specific purpose tool of process.Operation principle is that the recessed pinch roller that profit is rotated drives pipe to rotate, and roller devices slowly pressurizes to pipe under oil cylinder effect, thus the groove needed for being formed, use during in order to installing.The tubing processed can be used for the installation of the pipelines such as fire-fighting, running water, mine.
Traditional channelling machine is a certain amount of axis and radial-play because roller devices exists, and makes slot rolling precision not high, is difficult to use in the slot rolling processing of high-precision requirement.
Utility model content
Technical problem to be solved in the utility model is: provide the roller devices on channelling machine that a kind of machining accuracy is high.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of roller devices on channelling machine, comprise the mount pad that middle part is provided with step-like through hole, roller bearing is equipped with in mount pad, one end that roller bearing exposes mount pad is provided with colyliform pressure head, roller bearing is rotated by two groups, front and back bearing group and wears in the base, fore bearing group comprises two cylinder roller bearings and a deep groove ball bearing that set gradually from close colyliform pressure head one section, rear bearing group is needle roller and thrust ball combination bearing, base rear end is provided with back shroud, pan frontward end is provided with front shroud.
As the preferred scheme of one, the roller bearing other end is provided with oil filler point, and roller bearing is respectively equipped with combination bearing place the oil guiding hole be communicated with oil filler point at deep groove ball bearing, and roller bearing has been threaded connection lubricating cup in oil filler point aperture, and back shroud is provided with continuous oilhole.
As the preferred scheme of one, roller bearing front end is provided with the bearing gland of positioning cylinder roller bearing, and described front shroud is pressed on bearing gland; Roller bearing is provided with spacer ring between two cylinder roller bearings and deep groove ball bearing; Roller bearing is provided with positioning sleeve at deep groove ball bearing and between needle roller and thrust ball combination bearing; Roller bearing is threaded connection the round nut of location needle roller and thrust ball combination bearing at tail end, roller bearing is located needle roller and be provided with packing ring, floor clip between thrust ball combination bearing and round nut.
The beneficial effects of the utility model are: because roller bearing wears in the base by the bearing group rotation of two groups, front and back, fore bearing group comprises two cylinder roller bearings and a deep groove ball bearing that set gradually from close colyliform pressure head one section, rear bearing group is needle roller and thrust ball combination bearing, solve the problem of the device for elimination of axial-and radial-play of roller in process well, thus make machining accuracy to reach high requirement.
Because the roller bearing other end is provided with oil filler point, roller bearing is respectively equipped with combination bearing place the oil guiding hole be communicated with oil filler point at deep groove ball bearing, roller bearing has been threaded connection lubricating cup in oil filler point aperture, bearing is remained, and lubrication is good, thus reduce the radial-play of roller in process further, promote machining accuracy.
Owing to roller bearing being threaded connection the round nut of location needle roller and thrust ball combination bearing at tail end, roller bearing is located needle roller and be provided with packing ring, floor clip between thrust ball combination bearing and round nut, roller is made to be able to abundant restriction in the position of axis, guarantee that axial float controls in minimum zone, thus promote machining accuracy further.
