Abstract

A fixture for machining V-shaped cylinder of car is composed of left and right frames and at least two simple jacks. Said frame consists of a stand fixed to bench of mechine-tool, supporter welded to it and regulating sleeve barrel. Said supporter has a height-adjustable supporting axle for supporting and positioning the V-shaped cylinder and regulating screw. Its advantages include high stability and reliability, high efficiency and high machining accuracy.

Description

The anchor clamps that are used for processing automobile V type cylinder

The present invention relates to the anchor clamps that use in a kind of machining, especially for the anchor clamps of processing automobile V type cylinder.

Because V type cylinder being extensive use of in automobile industry, the automobile of higher gears uses V type cylinder mostly especially both at home and abroad, and the machining accuracy that requires is more and more higher, and general manufacturing process is difficult to guarantee its quality requirement.The anchor clamps of present normally used processing V type cylinder all are more traditional right angled triangle cavity structures.All be to be placed on V type cylinder on its triangular ramp and, to make a port surface perpendicular alignmnet machine tool of V type cylinder when using this anchor clamps by the anti-skid location of the sliding screw of the gear on it.For guaranteeing the vertical and suitable height of V type cylinder working position, the adjustment screw of some is housed also in the bottom of inclined-plane die cavity.Add man-hour anchor clamps and be fixed on the platen, on the V type cylinder fastening clips.Because the component that the responsive to axial force of V type cylinder own wt and cutter produces along the inclined-plane, can make workpiece produce the elasticity amount of moving and component to the vibration that the reaction force of cutter causes, machining accuracy is had a significant impact, and the quality of processing also is difficult to control.On the structure of these anchor clamps, also can find the unstability defective of himself, it does not have pressing plate that V type cylinder is pushed down, and causes occurring in the process rocking.We can also find that also there is the possibility that is difficult for the levelling straightening in the adjustment process in these anchor clamps in addition, and are careless slightly, deviation will occur.Even aligned, also may produce skew in the processing because of the component effect.Its another defective is that the preparation time is long, and is hard and time-consuming, during the processing other end, V type cylinder body need be pulled down, and retightens on lathe after the triangle anchor clamps will change 180 °, also V type cylinder will be placed on the triangle inclined-plane and readjust.Not only efficient is low but also the overproof probability of scrapping of product that process is also very high.In case scrap, lose also very big.

The objective of the invention is to overcome weak point of the prior art, provide a kind of reliable and stable, V type chucking cylinder is efficiently adjusted in operation.

The present invention is achieved in that these anchor clamps are made up of two left and right frames 10,11 and plural at least simple and easy jack, this frame 10,11 comprises a support 8 that can be fixed on the platen, support 8 inboards are welded with a support 12 that is shaped on chute 9 admittedly, the bolster 6 that can move in chute 9 can be fixing by clamp nut 13, also is shaped on its support 12 upper surfaces and regulates screwed hole 7.The outside at bearing 8 also is welded with a regulating sleeve 5 admittedly.Movably being equipped with one in its sleeve 5 on the supporting step 3 of adjusting rod 14 can be along the pressing plate 2 of fastening bolt 1 transfer.An adjusting rod trip bolt 4 also is housed on the regulating sleeve 5.

In a preferred embodiment, the regulating sleeve 5 that the outside is welded admittedly can be changed system into the cylinder that is welded in band step axle on the bearing 8 admittedly, and helicitic texture is made at cylinder step small end cylinder position, and pressing plate 2 is installed in it up and down between two nuts through chute.

In another preferred embodiment, simple and easy jack is made the pedestal of cylindricality or taper cup-shaped, be shaped on screwed hole in the pedestal, the bolt of packing into constitutes the screw thread jack.This jack can also be simple and easy small-sized hydraulic jack.

In another preferred embodiment, making trapezoidal support 12 or rectangle, can also be semicircular arc.

The present invention has overcome that the component effect causes the unsettled defective of crudy in the existing processing V type cylinder technology.The part support is steady about anchor clamps, and the axial force of bearing is unique, good rigidly, intensity height.Also overcome the influence of mechanical shock that component causes simultaneously to machining accuracy.Since there is not the influence of component cause, steadily of centre of gravity, the precision of processing is accurate, and scrappage is extremely low.Considered the factor of all kinds different sizes V type cylinder in the design, the free degree of adjusting is wide, once regulates, and is fast and reliable, and turn-over processing is fast, and time is short, and deviation is little, and is easy to control, the work efficiency height, and also steady quality is reliable.When the processing another side, need not dismantle V type cylinder body, only make turn-over and get final product.

Below in conjunction with accompanying drawing, the present invention is described in further detail.

Fig. 1 has described the V type chucking cylinder of being made by mechanical manufacturing method.These anchor clamps by about part frame and plural simple and easy jack (not shown) form.This frame comprises a support 8, is shaped on the support 8 to be used for fixing the hole that is connected on the platen.The inboard support 12 usefulness Sheet Metal Processing that solid weldering of support 8 form, its preferred plan be make trapezoidal, the fillet that periphery can be certain.The step surface of a bearing plate 2 should be made in adjusting rod 14 upper ends that solid welding is adorned in the regulating sleeve 5 of its rear side.Pressing plate should freely rotate on step surface.During use watt mouth of workpiece to be processed (V shape cylinder) inserted about on the bolster of part frame, make a port vertical table of its V type cylinder, adjust adjustment screw (not shown) and simple and easy jack (not shown) on the support 12 simultaneously, simple and easy jack generally is placed on about frame between the part and the anteroposterior position of the lower end watt actinal surface of V type cylinder adding man-hour, does corresponding the adjusting simultaneously.Clamping platen 2 and trip bolt 4 then.When processing the another port of V type cylinder, only stir accordingly, vertical working face gets final product.Above-described only is the preferred embodiments of the present invention.For the those of ordinary skill of mechanical industry, on the basis that does not break away from the principle of the invention, can also do other modification and improvement, also should be considered as belonging to protection scope of the present invention.

The present invention is applicable to the processing and the maintenance of the automobile V type cylinder of various types of different sizes.
