Abstract

The utility model relates to a lathe fixture, in particular to a plate fixture for lathe processing, comprising a plate fixture body and a chuck which is arranged at the inferior end surface of the fixture body. Two groups of hole combinations which comprise two location holes and at least three fixing holes respectively are positioned at the superior surface of the fixture body; a shape formed by line connecting the centers of both the location holes and the fixing holes of each group rotates or translates to coincide by a 180 degrees turnover in the same plane. The utility model is used for the clamping plate work pieces to lathe process the superior and inferior surfaces, and has the advantages of convenient clamping, higher efficiency, low cost, and voidance of the problems, existing in the plate work pieces clamping in the prior art, of longer time in clamping work pieces, low turning efficiency, cost input of the fixture, and increase of the turning cost of the plate work pieces.

Description

Turning attachment

Technical field

The utility model relates to a kind of turning attachment, particularly a kind of plate body Vehicle Processing anchor clamps.

Technical background

Vehicle Processing for the upper and lower surface of asymmetrical plate body, need the fixing and alignment pin location of attachment screw, in the prior art after machining a surface, need that workpiece is unloaded clamping and to another anchor clamps, continue Vehicle Processing, so just need to change anchor clamps or the cooperation of two chassis beds to two section Vehicle Processings of plate workpiece, caused the lengthening of clamping workpiece time, reduced the efficient of Vehicle Processing, or caused the cost input of anchor clamps, improved the Vehicle Processing cost of plate workpiece.

Summary of the invention

The utility model purpose is to provide a kind of clamping plate workpiece that is used for that its upper and lower surface is machined, convenient mounting and clamping, efficient is higher, lower-cost turning attachment, solved the longer of the clamping workpiece time that the clamping plate workpiece exists in the prior art, the efficient of Vehicle Processing is lower, or has caused the cost input of anchor clamps, has improved the problems such as Vehicle Processing cost of plate workpiece.

Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise tabular clamp body and the chuck of being located at the clamp body lower surface, described clamp body upper surface is provided with two groups of hole combinations that comprise 2 locating holes and at least 3 fixing holes respectively, and the shape that the central point line of described every group of locating hole and fixing hole constitutes is rotated in same plane after 180 degree upsets or translation overlaps.Be provided with on the plate workpiece one group with clamp body on locating hole and the corresponding clamping hole of fixing hole, when the upper surface of machining plate-like workpieces, the lower surface of plate workpiece is attached to the clamp body upper surface, adopts one group of hole combination attachment screw on the clamp body and alignment pin the plate workpiece positioning and fixing; After processing upper surface, plate workpiece is turned over turnback, make the upper surface of plate workpiece be fitted in the upper surface of clamp body, adopt another group hole combination attachment screw and alignment pin on the clamp body that the plate workpiece positioning and fixing is machined with the lower surface to workpiece.The utility model also can be used for milling process to be fixed the clamping of plate workpiece.Owing to avoided the replacing of anchor clamps or the replacing of lathe in the plate workpiece upper and lower surface Vehicle Processing process, thereby made things convenient for the clamping operation, improved operating efficiency; Clamp body can be used for the clamping plate workpiece simultaneously two surfaces of workpiece are processed, and then the cost input of anchor clamps when having reduced the Vehicle Processing plate workpiece.

As preferably, the combination of described every group of hole comprises 4 fixing holes, and one of them is standby fixing hole.Set up a standby fixing hole, when other fixing holes because of using or other reasons when going to pot, standby fixing hole can cooperate the clamping plate workpiece with other two intact fixing holes.

Therefore, the utlity model has and be used for the clamping plate workpiece its upper and lower surface is machined, convenient mounting and clamping, characteristics such as efficient is higher, and cost is lower.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment 1: as depicted in figs. 1 and 2, tabular clamp body 1 lower surface is provided with chuck 2, the upper surface 3 of clamp body 1 is provided with hole combination A and hole combination B, hole combination A comprises 2 locating hole A1 and 4 fixing hole A2, one of them fixing hole A2 is standby fixing hole, hole combination B comprises 2 locating hole B1 and 4 fixing hole B2, one of them fixing hole B2 is standby fixing hole, the shape that 2 locating hole B1 that B is made up in shape that 2 the locating hole A1 of hole combination A and the central point line of 4 fixing hole A2 constitute and hole and the central point line of 4 fixing hole B2 constitute translation coincidence again after the rotation in same plane after 180 degree upsets.

As shown in Figure 3 and Figure 4, when the upper surface of machining plate-like workpieces, the lower surface of plate workpiece 5 is attached to clamp body 1 upper surface, adopts hole combination A attachment screw 6 on the clamp body and alignment pin 7 plate workpiece 5 positioning and fixing; After processing upper surface, plate workpiece is turned over turnback, as shown in Figure 5 and Figure 6, make the upper surface of plate workpiece 5 be fitted in the upper surface of clamp body 1, adopt another group hole combination B attachment screw 6 and alignment pin 7 on the clamp body 1 that plate workpiece 5 positioning and fixing are machined with the lower surface to workpiece.

Claims

1, a kind of turning attachment, comprise tabular clamp body and the chuck of being located at the clamp body lower surface, it is characterized in that described clamp body upper surface is provided with two groups of hole combinations that comprise 2 locating holes and at least 3 fixing holes respectively, the shape that the central point line of described every group of locating hole and fixing hole constitutes is rotated in same plane after 180 degree upsets or translation overlaps.

2, turning attachment according to claim 1 is characterized in that the combination of described every group of hole comprises 4 fixing holes, and one of them is standby fixing hole.
