Description
Technical field
This utility model belongs to machining equipment technical field, is specifically related to a kind of for Centreless lathe Work-sheet pressing
With the device transmitted.
Background technology
Engineering machinery, machine-building are relatively big (such as a length of 6000mm, a diameter of 100mm, length to L/D ratio value
With diameter ratio for 60:1) the processing of round steel (tubing) cylindrical, generally use Centreless lathe processing.Centreless lathe can be quick, high
Effect removes the defects such as the decarburized layer of outer round surface, crackle, it is thus achieved that higher machining accuracy and relatively low roughness value, than generally
Technique improves efficiency several times to tens times, is especially suitable for processing super long and the big bar of allowance, can be widely used for machine
Make, car two produces, Production of bearing, major axis produce and the procedure for preparation of other machine-building.
Centreless lathe adds man-hour, and the compression of workpiece and transmission are to be promoted Lever machine by the fuel tank on pressure rack top by oil pressure
Structure, makes a pair roller tensioning realize, and the compression position of roller is the V-type conical surface, workpiece be placed in two rollers the V-type conical surface it
Between.After use after a while, the V-type conical surface of roller can wear and tear, and the distance between two rollers becomes big, the pressure of workpiece
Stability that is tight and that transmit reduces, and need to be replaced by two rollers, add the operating cost of equipment.
Summary of the invention
This utility model mainly solves the technical problem existing for above-mentioned prior art, it is provided that a kind of for Centreless lathe
Work-sheet pressing and the device of transmission.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals: one is used for not being in the mood for
The device that lathe workpiece compresses and transmits, including tapered roller and wheel platform, described tapered roller is divided into upper roller and lower rolling
Wheel, described upper roller is connected with roller adjusting pole by roller shaft, described roller adjusting pole be arranged over adjustment spiral shell
Bar, adjusts screw rod and contacts with roller adjusting pole, and described roller adjusting pole is provided with two square grooves, is provided with in square groove
Bolt, is connected roller adjusting pole, square groove with wheel platform by bolt, and described bottom roller passes through roller shaft and roller
Platform connects, and described tapered roller is longitudinally provided with arc groove along the conical surface, is radially provided with cannelure, arc groove and cannelure along the conical surface
It is crossed to form circular arc net groove.
As preferably, described upper roller quantity is two, and bottom roller quantity is two, and upper roller and bottom roller are in same
Vertical.
After unclamping bolt, by adjusting the space between above-mentioned adjustment screw rod and roller adjusting pole, upper roller is made to carry out
Move up and down, thus adjust the distance between two rollers.
Utility model has the advantages that and is arranged on by upper roller on roller adjusting pole, when after rolling wheel wear, it is possible to
Adjust the distance between upper roller and bottom roller up and down by adjusting screw rod, improve the stability that workpiece runs, improve and set
In standby service life, decrease the operating cost of equipment.Circular arc net groove adds the coefficient of friction of roller surface simultaneously, improves
Roller compression and the effect of conveying work pieces.Therefore this utility model has simple in construction, the feature such as reasonable in design.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model；
Fig. 2 is a kind of side sectional view of the present utility model；
Fig. 3 is the conical surface enlarged diagram of this utility model tapered roller.
In figure: 1, tapered roller；2, wheel platform；3, upper roller；4, bottom roller；5, roller shaft；6, roller adjusting pole；
7, screw rod is adjusted；8, square groove；9, bolt；10, arc groove；11, cannelure.
Detailed description of the invention
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment: a kind of for Centreless lathe Work-sheet pressing with the device of transmission, as Figure 1-3, including tapered roller
And wheel platform, described tapered roller is divided into upper roller and bottom roller, and described upper roller is by roller shaft and roller adjusting pole
Be connected, described roller adjusting pole be arranged over adjust screw rod, adjust screw rod contact with roller adjusting pole, described rolling
Wheel adjusting pole is provided with two square grooves, is provided with bolt, by bolt by roller adjusting pole, square groove and rolling in square groove
Wheel platform is connected, and described bottom roller is connected with wheel platform by roller shaft, and described tapered roller is longitudinally provided with circle along the conical surface
Arc groove, is radially provided with cannelure, arc groove and cannelure along the conical surface and is crossed to form circular arc net groove, and described upper roller quantity is two
Individual, bottom roller quantity is two, and upper roller and bottom roller are in same vertical.
After unclamping bolt, by adjusting the space between above-mentioned adjustment screw rod and roller adjusting pole, upper roller is made to carry out
Move up and down, thus adjust the distance between two rollers.
Upper roller is arranged on roller adjusting pole, when after rolling wheel wear, it is possible to adjust up and down by adjusting screw rod
Distance between roller and bottom roller, improves the stability that workpiece runs, improves the service life of equipment, decrease equipment
Operating cost.Circular arc net groove adds the coefficient of friction of roller surface simultaneously, improves the effect of roller compression and conveying work pieces
Really.
Finally it is pointed out that above example is only the more representational example of this utility model.Obviously, this practicality is new
Type is not limited to above-described embodiment, it is also possible to have many deformation.Every according to technical spirit of the present utility model to above example
Any simple modification, equivalent variations and the modification made, is all considered as belonging to protection domain of the present utility model.
