Description

Ram structure

Technical field

The utility model relates to a kind of ram structure, is the new design of the relative slide construction of parts in the machining apparatus, is particularly suitable for the feed motion of numerical control gantry machining tool Z-direction.

Background technology

Ram structure is a frame for movement commonly used in the machining apparatus, feed motion as numerical control gantry machining tool Z-direction, existing ram structure is that a balladeur train is arranged, on balladeur train, be processed with rectangular guideway, a part and the rectangular guideway of ram match, and ram can slide with respect to guide rail, and parts such as machine tool chief axis driving are installed on the ram, for the ram structure of existing type, side of ram contacts with the balladeur train body.The main shaft drives part is all in ram body inside, and ram gravity is big, and eccentric big, the turning torque that the balladeur train body is produced is big, makes the balladeur train body produce distortion easily, makes the steering capability of Rectangle guide bad.Rectangle guide and balladeur train body are one, just may produce trueness error in process, and causing ram ram when Rectangle guide moves up and down linearity generation error, particularly dither (high speed boringh) is to force the and then vibration of balladeur train body guide rail all the time.Make the Rectangle guide on the balladeur train body produce distortion, way rub is big.Install and adjust inconvenient.

Summary of the invention

The purpose of this utility model provides all has around a kind of ram radial location, ram and main shaft drives parts not to produce the ram structure of turning torque, not eccentric, indeformable, friction, light abrasion with respect to slide unit, overcomes the deficiencies in the prior art.

Ram structure of the present utility model, it comprises slide unit and the ram that matches with slide unit, it is characterized in that: square groove is arranged on the described slide unit and be fixedly connected with briquetting, the section of described ram is square and is fit in the space that groove on the slide unit and briquetting form, and is equipped with lash adjusting device between ram and slide unit, ram and briquetting.

Ram structure of the present utility model, wherein said lash adjusting device structure is: between ram and the slide unit, be provided with the adjustment plate of gauge gradual change between ram and the briquetting, the termination of adjusting plate is provided with concave station and groove, transfer bolt and investigation mission outside the city or town bolt in being threaded on described slide unit and the briquetting, the interior nut and the concave station of bolt transferred matches, and the nut and the groove of investigation mission outside the city or town bolt match.

Ram structure of the present utility model, wherein said lash adjusting device symmetry up and down arrange, and the bigger end of gauge of adjusting plate is positioned at the outer end.

Ram structure of the present utility model is provided with laminating plate between wherein said adjustment plate and the ram.

Ram structure of the present utility model, owing to square groove is arranged on slide unit and is fixedly connected with briquetting, the section of ram is square and is fit in the space that groove on the slide unit and briquetting form, at ram and slide unit, be equipped with lash adjusting device between ram and the briquetting, therefore, periphery at ram all has locating surface, guaranteed the linearity when ram moves with respect to slide unit, good rigidly, ram and main shaft drives parts do not produce turning torque with respect to slide unit, not eccentric, indeformable, friction, light abrasion is applicable to heavy cut, has guaranteed the precision of processing work, improve the life-span of lathe, remedied the defective of existing type ram.

Since between ram and the slide unit, be provided with the adjustment plate of gauge gradual change between ram and the briquetting, the termination of adjusting plate is provided with concave station and groove, transfer bolt and investigation mission outside the city or town bolt in being threaded on described slide unit and the briquetting, the interior nut and the concave station of bolt transferred matches, the nut and the groove of investigation mission outside the city or town bolt match, can arbitrarily adjust bolt as required, the side that nut by bolt leans concave station and groove moves the adjustment plate of gradient thickness, to change gap, location to ram, convenient, flexibly, reliable.

Because lash adjusting device symmetry up and down arranges, the bigger end of gauge of adjusting plate is positioned at the outer end, and therefore good the installation easily adjusted, to the accurate positioning of ram.

Owing to adjust between plate and the ram and be provided with laminating plate, have therefore that wear-resisting heat resistance is good, the advantage of long service life.

The specific embodiment

As shown in the figure: 1 is slide unit, and 3 is the ram that matches with slide unit 1.Be processed with square groove on slide unit 1, for bolting is connected, briquetting 2 forms square space with groove on the slide unit 1 between briquetting 2 and the slide unit 1.The section of ram 3 is square and matches with square space that groove on briquetting 2 and the slide unit 1 forms.Between ram 3 and slide unit 1, ram 3 and briquetting 2, be equipped with lash adjusting device, adjustment by lash adjusting device, slide in the square space that the groove of ram 3 on briquetting 2 and slide unit 1 formed, guaranteed steady, no turning torque, not eccentric when ram 3 drive main shaft drives parts move.

Above-mentioned lash adjusting device structure is as follows:

As shown in Figure 2: between the left surface and briquetting 2 of ram 3, be provided with the adjustment plate 4 of gauge gradual change between bottom side and the slide unit 1.

Shown in Fig. 3,4,5,6,7,8: be processed with concave station 8 on one side adjust the termination of plate 4, another side is processed with and groove 9, briquetting 2 and slide unit 1 and on be threaded in accent bolt 6 and investigation mission outside the city or town bolt), the nut of interior accent bolt 6 and concave station 8 match, the nut of investigation mission outside the city or town bolt 7 and groove 9 match.When transferring bolt 6 in rotating, its nut can press down concave station 8 moves down adjustment plate 4; Transfer bolt 6 in upwards rotating, upwards rotate simultaneously when raising bolt 7, its nut top groove 9 that can make progress makes and adjusts plate 4 and move up.Because adjusting the thickness of plate is gradual change, can change the gap of ram 3 peripheries when mobile.

Lash adjusting device symmetry up and down arranges, and the bigger end of gauge of adjusting plate 4 is positioned at the outer end, the gap can be turned down when the adjustment plate of upper and lower settings moves inward respectively like this, the gap can be transferred big when mobile outward respectively.

As shown in Figure 2: in order to improve anti-wear performance, bonding or screw is fixedly connected with laminating plate 5 on the adjustment plate 4 at the limit, left side of ram 3, bottom side place, and bonding or screw is fixedly connected with laminating plate 5 on the slide unit 1 at the upper side edge of ram 3, right edge place.

Be processed with the oilhole that joins with fueller on slide unit 1, the attrition surface place all around that oilhole leads to ram 3 is used to lubricate.
