Abstract
The pneumatic tailstock of numerically controlled lathe includes a pedestal, a carriage, rolling guide rails for the pedestal and the carriage to be installed on, a muff for installing thimble on bearing with great bearing capacity, a connecting seat fixed on the carriage, and computerized control system with pneumatic control element connected to the connecting seat. The present invention has improved tailstock structure, less contact and less wear between the muff and the tailstock, high precision, simple operation, high operation efficiency and other advantages.
Description
Technical field
The present invention relates to a kind of tailstock structure of numerically controlled lathe, especially realize the Pneumatic tailstock of numerically controlled lathe that pneumatic advance and retreat are regulated.
Background technology
Numerically controlled lathe is when processing parts, one end is clamped institute's processing parts by the main spindle box chuck, the other end is withstood by the tailstock thimble, because the big adjusting position of tailstock just maintains static after determining, and thimble need carry out axial minor adjustment on request before withstanding processing parts, and is realized by the axial adjustment of the shaft sleeve that thimble is installed.The shaft sleeve of prior art is to reach by shaking of tailstock handle, the axial location of thimble is by the skidding distance decision of shaft sleeve in tailstock, shake the tail wheel at tailstock rear portion during operation, hand one changes, shaft sleeve drives flexible 4~6 millimeters of thimble, by the clamping lever lock shaft sleeve at tailstock top, the axial location of thimble also is determined then, and this tailstock structure with engine lathe is identical.Its shortcoming is embodied in: at first, this hand adjusting inefficiency, operator's labour intensity is big, the frequent axial slip of shaft sleeve is regulated, quicken the fretting wear of tailstock and shaft sleeve, form the gap, cause directly influencing part processing precision and reduce service life of equipment; Secondly, select for use live centre or dead center decide according to the speed and the precision of processing, generally in High-speed machining, element precision is selected for use live centre under the less demanding situation, because of dead center should not high speed, easily kill; Add man-hour at low speed, the element precision requirement is higher again, selects dead center for use.Live centre is because of reasons in structure, poor rigidity, and the life-span is low, easily causes end play, and machining accuracy is descended.Therefore, how to improve the tailstock structure, make tailstock improve precision, easy and simple to handle, reduce operator's labour intensity, can use inexpensive dead center to use again to improve machining accuracy, reduce cost, finish the Pneumatic tailstock of axial adjustment by numerically controlled lathe computer system control program, will be the problem that the present invention will inquire into.
Summary of the invention
Goal of the invention of the present invention is to overcome the defective of prior art and a kind of syndeton of utilizing computer system control pneumatic element and then driving improved tailstock structure and planker and base is provided, reach the lathe Pneumatic tailstock of the slippage adjusting of regulating shaft sleeve and thimble axial location, thereby avoid the skimming wear of shaft sleeve and tailstock sliding surface, be used in combination inexpensive dead center and make it have the live centre function, to improve mechanical precision, increase the service life, increase work efficiency and to alleviate operator's labour intensity.
Goal of the invention of the present invention is achieved through the following technical solutions.
A kind of Pneumatic tailstock of numerically controlled lathe, it comprises the base that is fixed on the numerically controlled lathe guide rail, and base is provided with the planker of its axial slip relatively, and the planker end face is provided with the tailstock that includes shaft sleeve and thimble, the relative planker axial location of tailstock, vertical back of regulating are fixed, and it is characterized in that:
Fixing a pair of fixed guide of a, described base boss two lateral surfaces vertically or rolling guide; Described planker two inboard fixing a pair of rolling guide or fixed guides vertically; Be provided with by the isolated rolling member of retainer in the every pair of fixed guide and the rolling guide;
The rear, tailstock rear of b, described planker end face is provided with the Connection Block of being realized promotion by the pneumatic element of computer system control or hand push button crawl;
In the bearing by at least 2 bidirectional stress inlaying the interplanting axial location, afterbody is provided with the axial adjustment part to shaft sleeve two supports in c, the described tailstock in tailstock.
Described pneumatic element comprises the cylinder axis that is connected with Connection Block, and the cylinder that cylinder axis is installed is fixed on the mount pad of fixing with base.
Described tailstock is to be provided with equipped mutually 2 locating slots and 2 location lugs on faying face with the axial location of planker.
The bidirectional stress bearing of described bolster sleeve is conical bearing or angular contact bearing, is provided with 2~5.
Compared with prior art, the present invention has improved tailstock structure and the relative Sliding Structures of planker with base, promptly between planker and base, be provided with 02260472.3 the roller guide rail of a pair of the applicant in first to file, the axial adjustment of thimble is realized by the pneumatic element of computer system control simultaneously, be of the same moved further realization of the axial adjustment of thimble by shaft sleeve and tailstock, so there is not the frequent contact wear between shaft sleeve and the tailstock, can use inexpensive dead center with live centre function, former manual advance and retreat have been changed, Pneumatic tailstock after the improvement is because of having adopted the roller guide rail, so coefficient of rolling friction is low, the guiding clearance is little, machinery mobile accuracy height helps the machining high-precision engineering goods, also has easy and simple to handle simultaneously, high efficiency, long service life, characteristics such as operator's labour intensity is low.

The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail again.
Shown in Fig. 1~4, Pneumatic tailstock of numerically controlled lathe comprises the base 9 that is installed on the numerically controlled lathe guide rail, and two guide-track grooves of base end face can be made axial adjustment along the lathe guide rail, especially runs into when processing is short expects, generally regulates thus, after the adjusting base is fixed.
Tailstock 3 is located on the planker 8, and the axial location of tailstock on planker done vertically to regulate the back and be fastenedly connected one by screw by the equipped location of realizing of 2 location lugs 10 (or locating slot 17) of 2 locating slots 17 (or location lug 10) and the planker end face of tailstock bottom.Simplified the tailstock structure, must tail wheel must set lever yet.Shaft sleeve 2 outer surfaces in the tailstock are multidiameter, be bearing in 2 conical bearings 14 in the tailstock, this bearing is made inside and outside circle axial location with shaft sleeve self omoplate face and edge cover 13, can bear bigger axial force and radial load, the taper hole of shaft sleeve head is equipped mutually with the taper shank of dead center 1, and 15 And are tight by regulating part nut 16, packing ring for afterbody.
Fixing a connecting seat 4 on the planker at tailstock rear, this Connection Block is connected with the pneumatic element of computer system control, pneumatic element comprises cylinder axis 5, cylinder 7 is installed on the mount pad of fixing with base 6, cylinder axis in the cylinder promotes Connection Block and drives planker, tailstock, shaft sleeve, thimble to make locking phase the base axial slip is regulated under computer system control, the shaft sleeve here only works the thimble effect of installing, thimble holds out against part to be processed rear axle sleeve and thimble rotates synchronously, do not do move to regulate, so and fricton-tight wear problem between the tailstock.
The computer system of control Pneumatic tailstock is realized by artificial crawl or programming realizes automatically.
