Abstract

The utility model discloses a clamping device, especially a centering clamping device for tightly clamping and fixing of workpieces on the machine tool. The invention is characterized in that the seat [10] with a slideway [3] is set. Relative V-type trough slide clamping part [1, 17] is set assembled with the slideway [3]. On the seat [10], a gear [6] joggled with racks [4, 5] is installed. The racks [4, 5] are symmetrically set relative to the center of the circle of the gear [6] and fixed and connected with the slide clamping part [1, 17]. The rack [4] is connected to the piston rod [11] which is assembled with the oil cylinder [7] which is fixed and connected to the seat [10]. The device can capture the centering during tightly clamping the workpiece in-phase. The clamping is stable and reliable and the centering precision is high. The utility model is applicable for workpieces in all sizes and is with good currency, time-saving, effort-saving. The utility model not only reduces the labor strength, but also reduces the processing cost of the parts.

Description

Centering and clamping apparatus

Technical field:

The utility model relates to a kind of clamping device, particularly a kind of centering and clamping apparatus of on the lathe workpiece being fixedly clamped of being used for.

Background technology:

When workpiece is carried out machined, especially the diameters of axle such as automobile axle housing are changed greatly, the shaft-like workpiece that surface roughness is relatively poor should fasten workpiece clamp on the workbench of lathe earlier, and then carries out metal cutting processing.Current clip fastens such workpiece and extremely bothers, to support workpiece with v block or other backing plates etc., also to utilize pressing plate, bolt etc. that workpiece is fixedly clamped, meanwhile also will be to heart centering, every work is carried out respectively, can not finish synchronously, also harmonious mutually, waste time and energy, the labour intensity height, production efficiency is low.

Summary of the invention:

The purpose of this utility model provides that a kind of support, clamping, centering are finished synchronously, time saving and energy saving, labour intensity is low, efficient is high centering and clamping apparatus, overcomes the deficiencies in the prior art.

Technical solution of the present utility model is: a kind of centering and clamping apparatus, it is characterized in that: be provided with support 10, on support 10, be provided with slideway 3, is furnished with relative V-type slot type slip clamping element 1,17 mutually with slideway 3, the gear 6 that is meshed with tooth bar 4,5 is housed on support 10, tooth bar 4,5 centers of circle with respect to gear 6 are symmetrical arranged and are fixedly connected with slip clamping element 1,17 respectively, tooth bar 4 stopper rod 11 of taking over a job, and the oil cylinder 7 that matches with piston rod 11 is fixedly connected with support 10.

Connect for dovetail groove type between described slideway 3 and the slip clamping element 1,17.

Described support 10 is provided with the roller 16 that supports tooth bar 4,5, and roller 16 is contained in to be adjusted on the piece 8, adjusts piece 8 and is fixed on the support 10, adjusts between piece 8 and the support 10 and is provided with adjusting pad 18.

The utility model compared with prior art has following advantage: owing to be furnished with relative V-type slot type slip clamping element on the slideway of support, the gear that is contained on the support is furnished with tooth bar, tooth bar connects with fixed with the slip clamping element, tooth bar is by hydraulic oil cylinder driving work, the centering so this device can be felt relieved when workpiece is clamped, finish synchronously, clamp reliable and stable, to heart precision height, be applicable to the workpiece of all kinds of specifications, versatility is good, and is time saving and energy saving, reduce labour intensity, also reduced the processing cost of part simultaneously.

Description of drawings:

Fig. 1 is the structural representation of the utility model specific embodiment;

Fig. 2 is that schematic diagram is looked on a left side shown in Figure 1.

The specific embodiment: as shown in the figure: 10 is support, can adopt metal casting after the machined moulding.Be provided with slideway 3 on support 10, support 10 can be structure as a whole with slideway 3 or bolting connects.Is furnished with relative V-type slot type slip clamping element 1,17 mutually with slideway 3, the V-type groove of slip clamping element 1,17 is oppositely arranged, connect for dovetail groove type between slideway 3 and the slip clamping element 1,17, be that slideway 3 is swallowtail shape, the bottom of slip clamping element 1,17 and slideway 3 match and partly are the dovetail groove shape.Be connected with gear 6 at support 10 upper bearing (metal)s, gear 6 is meshed with tooth bar 4,5, and tooth bar 4,5 centers of circle with respect to gear 6 are symmetrical arranged, and promptly tooth bar 4,5 lays respectively at the both sides of gear 6, and when gear 6 rotated, tooth bar 4,5 moved round about.Tooth bar 4 is fixedly connected with slip clamping element 1, and connecting mode fixes by connecting locating piece 13 and key 14 connections, stretching out with slip clamping element 1 in the slotted hole of connection locating piece 13 on slideway 3.Tooth bar 5 is fixedly connected with slip clamping element 17, and connecting mode fixes by connecting locating piece 19 and key 20 connections, stretching out with slip clamping element 17 in the slotted hole of connection locating piece 19 on slideway 3, has reached the purpose of location.For convenience, connect locating piece 13 and tooth bar 4, connect locating piece 19 and tooth bar 5 is structure as a whole.Described tooth bar 4,5 is fixed together with bolt 21 and slip clamping element 1,17 respectively.Make promptly to locate again between two and fix.Tooth bar 4 stopper rod 11 of taking over a job, connecting mode is a thread connection bolt 12 on piston rod 11, insert the termination of bolt 12 and tooth bar 4 links connects in the groove on the locating piece 13.Connect with support 10 bolting with the oil cylinder 7 that piston rod 11 matches.Described support 10 is provided with the roller 16 that supports tooth bar 4,5, and roller 16 usefulness axle 15 is contained in to be adjusted on the piece 8, adjusts piece 8 and is bolted on the support 10, adjusts between piece 8 and the support 10 and is provided with adjusting pad 18.When tooth bar moved, roller 16 rolled behind at tooth bar tooth bar is played a supporting role.

The course of work is: earlier support 10 is bolted on the workbench of lathe, oil cylinder 7 joins with hydraulic control device, when hydraulic control device drives oil cylinder work, tooth bar 4 is driven by piston rod 11 and moves, gear 6 rotates thereupon, meanwhile tooth bar 5 and tooth bar 4 same moved further, move in opposite directions along slideway 3 through connecting locating piece 13,19 drive slip clamping elements 1,17, when slip clamping element 1,17 is close relatively, can pass through relative V-type groove clamping work pieces on it, but and because the effect automatic capturing centering of V-type groove.According to the specification difference of workpiece, the thickness that can adjust the adjustment backing plate 2 on the V-type groove makes it to be suitable for workpiece.When slip clamping element 1,17 relatively away from the time, can remove being fixedly clamped to workpiece.
