Abstract

The utility model relates to a high-precision clamp used for hole turning, comprising a positioning plate, wherein the positioning plate is vertically provided with a bearing plate; a location pin and two stop blocks are arranged on the bearing plate; a sliding chute is arranged between the two stop blocks; screw rods are arranged on the stop blocks; one end of an L-shaped support frame is located in the sliding chute; the other end of the support frame is provided with a compression screw; the positioning plate is also fixedly connected with a balance block by a screw. The high-precision clamp used for hole turning is simple in structure, flexible and convenient to use, simple in clamping and high in processing precision.

Description

High-accuracy Che Kongyong fixture

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to the positioning fixture for workpiece being carried out to Drilling operation.

Background technology

Workpiece 9 as shown in Figure 1, it is two side plates that are vertically connected in rectangular base plate, according to technical requirement, need on side plate, process respectively a through hole 10, it is being positioned and is adding man-hour, using plain clamp to acquire a certain degree of difficulty to its location, especially will guarantee machining accuracy, must use special frock just can meet the demands, and frock must be easy to use, clamping efficiency is high, can guarantee again its machining accuracy simultaneously.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of high-accuracy Che Kongyong fixture, and it is simple in structure, flexible and convenient to use, and clamping efficiency is high, and machining accuracy is high.

The technical scheme that the utility model adopts is as follows:

High-accuracy Che Kongyong fixture, comprises positioning disk, is vertically installed with loading plate on positioning disk, on loading plate, with alignment pin and two blocks, and between two blocks, chute is set, on block with screw rod, one end of L shaped bracing frame is positioned at chute, and the other end of bracing frame is with screw-in compression; On positioning disk also by the screw balance weight that is connected.

The utility model has the advantage of: according to the structure of workpiece, loading plate is installed on positioning disk for positioning workpieces, alignment pin is set simultaneously to carry out spacing from the sidewall of workpiece, by the screw rod on block, from another sidewall of workpiece, workpiece is clamped again, by being installed on bracing frame, housing screw compresses location from the front of workpiece in addition, and simple in structure, flexible and convenient to use, clamping efficiency is high, and machining accuracy is high.

Accompanying drawing explanation

Fig. 1 is use state diagram of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As shown in Figure 1, the utility model comprises positioning disk 1, on positioning disk 1, be vertically installed with loading plate 2, loading plate 2 is for carrying workpiece 9, on loading plate 2 with alignment pin 3 and two blocks 6, alignment pin is three, from the both sidewalls of workpiece 9, to workpiece 9, carry out spacing respectively, and chute 4 is set between two blocks 6, on block 6 with screw rod 7, by adjusting screw(rod) 7, can to workpiece 9, clamp from another sidewall of workpiece 9, two blocks 6 are set, can make workpiece 9 stressed evenly, improve positioning precision, one end of L shaped bracing frame 5 is positioned at chute 4, the other end of bracing frame 5 is with screw-in compression, bracing frame 5 can move along chute 4, be convenient to dismounting or install, by described screw-in compression, can compress from the front of workpiece 9, on positioning disk 1, also by the screw balance weight 8 that is connected, can improve the stationarity of high-speed turning,

Using method of the present utility model is as follows:

The first step, is installed on positioning disk 1 on the scroll chuck of lathe;

Second step, is placed in workpiece 9 on loading plate 2, makes two sidewall prop up alignment pin 3;

The 3rd step, regulates the screw rod 7 on two blocks 6 from another sidewall of workpiece 9, it to be clamped;

The 4th step, along the position of chute 4 adjusting support frames 5, makes described screw-in compression be pressed in the front of workpiece 9;

The 5th step, starts the side plate of lathe on workpiece 9 through hole 10 of getting on the bus out.

More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
