Abstract

The utility model relates to a metal grinding and cutting machine tool. The metal grinding and cutting machine tool is assistant equipment for protecting a bed surface and a guide rail for a tail seat. A front clamping plate, a rear clamping plate, a left side plate, and a right side plate form a frame structure which is corresponding to the tail seat in a dismountable connection mode. Connecting shafts are arranged on the front clamping plate and the rear clamping plate. Support frames are arranged on the side plates with sinuses. Eccentric shaft assemblies are installed on the support frames. The eccentric shaft assemblies are composed of eccentric shafts, handles, bearings, and positioning blocks. The handles are installed on the end parts of shafts. The positioning blocks which are movably matched with the shafts are installed on the positions of front supports of the shafts. The bearings are installed on the eccentric parts of the shafts. The metal grinding and cutting machine tool can avoid the abrasion of the bearings and the shafts, and can effectively protect a bed surface and a tail seat of a grinding machine.

Description

Grinding machine bed surface and tailstock protective device

The utility model relates to the metal removal lathe, a kind of complementary equipment of protection bed surface and tailstock guide.

Grinding machine generally is used for fine finishining, finishes whole manufacturing procedure, particularly for high rigidity special material and quenching workpiece, often can only process with grinding machine, so it is widely used in the cutter manufacturing, and the engine manufacturing is in the precision optical machinery process industry.The guide pass that the bed surface of grinding machine, tailstock cooperate with it all is very smooth, straight precision surface, relies on the precision-fit relation between bed surface guide rail and tailstock, keeps the machining accuracy of lathe.The deficiencies in the prior art part mainly is: during mobile tailstock, all there are wearing and tearing in both, can reduce the precision of lathe.Promptly, in order to adapt to the requirement of workpiece installation site, often need on tooth bar, to rotate by handwheel driving gearshaft, gear, the sliding bed surface of tailstock is moved, owing to do not have corresponding bed surface and tailstock protective device, no matter how clean environmental aspect is, how careful maintaining work is, and how abundant lubricating condition is, tailstock moves on bed surface, rigid member directly contacts, rubs with rigid member, always has wearing and tearing, causes the machining accuracy of grinding machine to descend; Generally, using after several years just needs grinding machine bed surface, tailstock place under repair, tries hard to recover the quality of fit between bed surface and tailstock guide.In addition, the running part that tailstock is moved, complex structure, cost height.

The purpose of this utility model is to avoid weak point of the prior art, and when a kind of mobile tailstock is provided, grinding machine bed surface and the tailstock protective device product that can avoid both to wear and tear.

Can take following technical scheme to realize purpose.Grinding machine bed surface and tailstock protective device, by forward and backward clamping plate, left and right side plate, with removably connect, formation and the corresponding frame structure of tailstock, on the forward and backward clamping plate connecting axle is housed, have on the side plate of notch and support be housed, setting-up eccentricity shaft assembly on the support; The eccentric shaft assembly is made of eccentric shaft, handle, bearing and locating piece, and handle is installed in the end of eccentric shaft, with eccentric shaft locating piece movingly be installed in the axle preceding supporting place, bearing be installed in the axle eccentric position on.

The relative prior art of the technical program has following advantage and effect:

Can effectively protect the bed surface and the tailstock of grinding machine, when mobile, make rolling movement in the lathe bed technology groove, replace the sliding friction campaign between rail level with bearing, both rail levels disengage fully, do not have wearing and tearing, also lightly freely; Simple in structure, cheap, flexible and convenient to use; Can save maintenance, upkeep cost greatly, obviously prolong the service life of bed surface and tailstock.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 1 is a kind of structural representation of grinding machine bed surface and tailstock protective device;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the side view of Fig. 1;

Fig. 4 is a kind of structural representation of offset assembly;

Fig. 5 is that K is to view.

Under the prerequisite that satisfies the said structure requirement, as for the integral body of grinding machine bed surface and tailstock protective device and specific constructive form, the size of other each several part member; Connection between member, position relation etc. all can be taken the circumstances into consideration to set according to using needs, and they are to the not influence of serviceability of grinding machine bed surface and tailstock protective device.

Grinding machine bed surface shown in the drawings and tailstock protective device embodiment, it is by having forward and backward clamping plate 1,2, left and

right side plate

3,4, with fastening the removably connecting, connecting axle 5 be housed on formation and the corresponding frame structure of tailstock, the forward and backward clamping plate of screw element, support 6 is housed, setting-up eccentricity shaft assembly on the support on the left side plate; The eccentric shaft assembly is made of eccentric shaft 7, handle 8, bearing 9 and locating piece 10, and handle is installed in the end of eccentric shaft, with axle locating piece movingly be installed in the axle preceding supporting place, bearing be installed in the axle eccentric position on.

Installation and application, remove earlier on the tailstock in order to the tooth bar engaged transmission, realize the gear shaft that tailstock moves; Dismantle the framework of protective device, in the past, rear plate was fitted in the front/rear end place of tailstock respectively, replace original gear shaft, run through forward and backward clamping plate and tailstock with connecting axle, promptly use connecting axle in the gear axis hole of tailstock with forward and backward clamping plate and tailstock three, be tightened to one; Again left and right side plate is installed in the both sides of forward and backward clamping plate, fastening firm getting final product.When needing mobile tailstock, the supporting axle head of eccentric shaft assembly packed in the axis hole 11 of side plate support and with locating piece and another support centering, form the eccentric shaft assembly another turn round fulcrum, assembling finishes.If tailstock and lathe are in tightening state, can unclamp from the notch of side plate binding thread spare with tailstock and lathe bed.Upwards the handle of eccentric rotation axis assembly, contact, locate with skirt walls to button, eccentric shaft turns over certain angle, bearing is made sliding motion along the technology groove transition arc on lathe bed top, eccentric part makes protective device together with the tailstock certain distance that raises, the transition arc of technology groove makes protective device outwards pass certain distance together with tailstock by bearing again simultaneously, tailstock and bed surface guide rail disengage fully, and the bearing everywhere of protective device eccentric shaft assembly is in the technology groove on grinder bed top; Use the hand propelled tailstock, the bearing of protective device is made rolling movement in the lathe bed technology groove, realizes the adjustment of tailstock on bed surface easily, moves.To desired location, install workpiece after, rotate the eccentric shaft assembly handle, tailstock is set back; Unload the eccentric shaft assembly; From the notch of side plate, routinely the binding thread spare between tailstock and lathe bed is fastened, can carry out grinding again.

The result of use of accompanying drawing illustrated embodiment is good.

The technical program is applicable to the various grinding machines that tailstock is arranged.
