Abstract
The invention relates to a rolling flexible pre-stressed auxiliary guide rail device for a heavy machine tool. The rolling flexible pre-stressed auxiliary guide rail device is characterized by comprising an auxiliary guide rail arranged on the outer side of the lower part of an anti-backlash gear box of the machine tool, wherein the length of the auxiliary guide rail is equal to that of a machine tool guide rail; and elastic support assemblies are arranged on the left and right sides of the anti-backlash gear box. In the structure, pre-supporting force is generated through the elastic support assemblies, so that the gravity center of a large supporting plate of the machine tool falls between the two guide rails, closes to one third part of the auxiliary guide rail and is matched with roller support, so that torsion and climbing phenomena are eliminated basically; and furthermore, the phenomenon of warping is avoided effectively, and the running stability of equipment is enhanced.
Description
Technical field
The invention belongs to heavy-duty engine lathe manufacturing technology field, particularly relate 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 Z axis, 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, what add Z axis drive system, track lubrication system moves and has increased that operating personnel walk on stage, safety barrier outward, and tower cutter platform changes the frame knife rest and causes 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, the seesaw phenomenon of formation take outer guide as fulcrum, the operator is in the mobile variation that cutter trade and size occur workpiece that is reflected to of walking on stage, fine finishining operation size is uncontrollable, affects 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 adjustment difficulty is very large and because secondary guide rail self poor rigidity, cause stability low, because of sliding friction twisting and creeping phenomenon are arranged in the use.
Summary of the invention
The present invention 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 present invention takes 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 present invention 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 turn wheel shaft is arranged, be set with spring on the wheel shaft in the described retainer, be screwed with adjusting nut on the lower end wheel shaft of described spring, the lower end of described wheel shaft is fixedly connected with retainer by jackscrew, the hinged roller that is equipped with in the lower end of described wheel shaft, described roller and auxiliary guide rail coupling.
Advantage and good effect that the present invention has are: owing to increase flexible auxiliary guide rail prestressing force supporting construction, thereby level and the linear precision requirement of secondary guide rail have been reduced, be elimination twisting and the creeping phenomenon of rolling but adopt ball bearing to become and slide, effectively avoided in addition the seesaw phenomenon, improved the stability of equipment operation.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is that the present invention uses state diagram.
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, adjusting nut; 4-5, jackscrew; 4-6, roller; 5, lathe big palette.
The specific embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be 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 lathe clearance elimination gear case 1 lower outside, 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 turn 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 adjusting nut 4-4 on the lower end wheel shaft of described spring 4-3, the lower end of described wheel shaft 4-2 is fixedly connected with retainer 4-1 by jackscrew 4-5, the hinged roller 4-6 that is equipped with in the lower end of described wheel shaft 4-2, 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 simultaneously roller supporting, elimination twisting and creeping phenomenon have effectively been avoided in addition the seesaw phenomenon, have been improved the stability of equipment operation.
The above only is to preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, any simple modification that every foundation technical spirit of the present invention is done above embodiment, equivalent variations and modification all belong in the scope of technical solution of the present invention.
