Abstract

The utility model relates to a rolling flexible prestressing force auxiliary guide rail device of a heavy-duty lathe. The rolling flexible prestressing force auxiliary guide rail device of the heavy-duty lathe is characterized by comprising an auxiliary guide rail installed on the outer side of the lower portion of an anti-backlash gear box of the heavy-duty lathe, wherein the length of the auxiliary guide rail is equal to that of each guide rail of the heavy-duty lathe, and elastic supporting assemblies are installed on the left side and the right side of the anti-backlash gear box. According to the structure, pre-support force is generated through the elastic supporting assemblies, the center of gravity of a lathe big supporting plate is arranged between two guide rails, and is close to the position of one third of the auxiliary guide rail, an idler wheel is used for supporting in a cooperated mode at the same time, the phenomenon of twisting and the phenomenon of creeping are basically eliminated, in addition, the phenomenon of plate warping is effectively avoided, and stability of operation of equipment is improved.

Description

A kind of heavy-duty engine lathe rolling flexible prestressing auxiliary guide rail device
Technical field
The utility model belongs to heavy-duty engine lathe manufacturing technology field, particularly relates to a kind of heavy-duty engine lathe rolling flexible prestressing auxiliary guide rail device.
Background technology
Traditional heavy sleeping carriage is divided into three guide rails, four guide rails, five guide rails etc.The heavy sleeping carriage of three guide rails is for the gear of eliminating the Z axle, the match gap of tooth bar in CAM transforms, the clearance elimination gear case is installed in former feed change unit position, the bottom of the outside of tool guide saddle and is driven servomotor, add Z axle drive system, track lubrication system outer move and increased that operating personnel walk on stage, safety barrier and tower cutter platform change the frame knife rest and cause the saddle out-shift of gravity center; Cause saddle and the accelerated wear test of tailstock knife rest common guide rails pressing plate, saddle outer guide edge aluminium wear liner, formation is the seesaw phenomenon of fulcrum with the outer guide, the operator moves on walking on stage and is reflected to the variation that cutter trade and size take place on the workpiece, fine finishining operation size is uncontrollable, influences product quality.The present domestic secondary guide rail of rigidity that adopts of the same trade is alleviated the seesaw phenomenon, but performance difficulty requires secondary guide rail and machine tool guideway high conformity, and it is very big and because secondary guide rail self rigidity is poor to adjust difficulty, cause stability low, because of sliding friction twisting and creeping phenomenon are arranged in the use.
Summary of the invention
The utility model provides a kind of simple in structure, convenient for installation and maintenance, heavy-duty engine lathe rolling flexible prestressing auxiliary guide rail device of avoiding the seesaw phenomenon for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of heavy-duty engine lathe rolling flexible prestressing auxiliary guide rail device, it is characterized in that: this auxiliary guide rail device comprises the auxiliary guide rail that is installed in the lathe clearance elimination gear lower box part outside, described auxiliary guide rail and machine tool guideway are isometric, in the left and right sides of clearance elimination gear case resilient support assemblies are installed.
The utility model can also adopt following technical measures:
Described resilient support assemblies comprises the retainer that is connected with the clearance elimination gear case, wear on the described retainer to change wheel shaft is arranged, be set with spring on the wheel shaft in the described retainer, be screwed with the adjustment nut on the lower end wheel shaft of described spring, fixedly connected with retainer by jackscrew in the lower end of described wheel shaft, the hinged roller that is equipped with in the lower end of described wheel shaft, described roller and auxiliary guide rail coupling.
Advantage and the good effect that the utlity model has are: owing to increase flexible auxiliary guide rail prestressing force supporting construction, thereby the level and the straight line required precision of secondary guide rail have been reduced, adopt ball bearing to become slip and can eliminate twisting and creeping phenomenon substantially, effectively avoided the seesaw phenomenon in addition, improved operation stability of equipment into rolling.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the utility model user mode figure.
Among the figure: 1, lathe clearance elimination gear case; 2, auxiliary guide rail; 3, machine tool guideway; 4, resilient support assemblies; 4-1, retainer; 4-2, wheel shaft; 4-3, spring; 4-4, adjustment nut; 4-5, jackscrew; 4-6, roller; 5, lathe big palette.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 to Fig. 3, a kind of heavy-duty engine lathe rolling flexible prestressing auxiliary guide rail device, this auxiliary guide rail device comprises the auxiliary guide rail 2 that is installed in the outside, lathe clearance elimination gear case 1 bottom, described auxiliary guide rail 2 is isometric with machine tool guideway 3, in the left and right sides of clearance elimination gear case resilient support assemblies 4 is installed.
In the said structure, described resilient support assemblies 4 comprises the retainer 4-1 that is connected with the clearance elimination gear case, wear on the described retainer to change wheel shaft 4-2 is arranged, be set with spring 4-3 on the wheel shaft 4-2 in the described retainer, be screwed with on the lower end wheel shaft of described spring 4-3 and adjust nut 4-4, the hinged roller 4-6 that is equipped with in the lower end of described wheel shaft 4-2 is fixedlyed connected by jackscrew 4-5 in the lower end of described wheel shaft 4-2 with retainer 4-1, described roller 4-6 and auxiliary guide rail 2 couplings, described roller adopts ball bearing.
Said structure is adjusted the pre-support force of spring by adjusting nut, thereby the center of gravity that makes lathe big palette 5 drops between two guide rails, and 1/3rd places near auxiliary guide rail, cooperate roller to support simultaneously, basic twisting and the creeping phenomenon eliminated effectively avoided the seesaw phenomenon in addition, improved operation stability of equipment.
The above only is to preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model is to any simple modification that above embodiment did, equivalent variations and modification all belong in the scope of technical solutions of the utility model.
