Abstract

The utility model belongs to the field of machine tools and mainly relates to an auxiliary device of a milling machine, which is composed of a top beam, a base, a supporting plate, an upright post, a piston bush, a piston rod, a hydraulic oil cylinder and a connecting plate. The device adopts a frame style composite structure that two or more oil cylinders are arranged, the piston rod in the hydraulic oil cylinder is used for clamping or release a sample simultaneously, by a switch of a push-button plate switch on the machine tool, the purpose of self-clamping or releasing is achieved, and by linking with the machine tool, the automatic cycle of working process is realized. The utility model has the characteristics that the production efficiency is high, and the clamping and releasing is automatic, fast and safe.

Description

The plate tensile sample hydraulic clamp

Technical field

The utility model belongs to machine tool field, relates to the servicing unit of lathe, particularly the servicing unit of milling machine.

Background technology

The sheet material of each metallurgical works production is before dispatching from the factory, all need take a sample and carry out various performance detection, the user of sheet material will take a sample too, performance to sheet material is reviewed. in the prior art, the two-sided processing of the plate tensile sample that factory uses before opening shoulder, all adopt saw, mill, dig, the grinder preface is processed, adopt flat-nose pliers to clamp to sample, clamping tool and processing technology fall behind, production efficiency is low, and labor strength is big, the processing cost height, sometimes sheet material can not get timely check, and sheet material can not in time be put in storage and supply (" physical testing) " 2002 years the 2nd, 3 phases).

Summary of the invention

The purpose of this utility model is to provide a kind of and can clamps or loosen, and once can clamp the plate tensile sample hydraulic clamp of a placate sample.

At above-mentioned purpose, the utility model plate tensile sample hydraulic clamp adopts frame type combined structure, and the hydraulic jack more than 2 is set, and utilizes piston rod in the hydraulic jack simultaneously sample to be clamped or loosens.And the switch by the push-button station on the lathe, with lathe interlock, the purpose that reaches automatic clamping or loosen, realize the Automatic Cycle of process.

Now in conjunction with the accompanying drawings, the utility model is elaborated:

Accompanying drawing 1 is the structural representation of the utility model plate tensile sample hydraulic clamp.

Accompanying drawing 2 is the A-A cut-away view of accompanying drawing 1.

Find out that by Fig. 1 and Fig. 2 the utility model plate tensile sample hydraulic clamp is made up of back timber 1, base 2, support plate 3, column 4, piston bush 5, piston rod 6, hydraulic jack 7 and web joint 13.Hydraulic jack 7 is fixed on the back timber 1 by pin 14, piston rod 6 is sleeved in the piston bush 5, both are sleeved in the hydraulic jack 7 in the lump, after base 2 is located by positioning key 11, be fixed in bolt 10 on the worktable 12 of lathe, 4 on column is bearing on the base 2, and web joint 13 is connected and fixed with column 4, and back timber 1 and web joint 13 are connected and fixed by bolt 15.

8 is milling cutter among the figure, and 9 is sample.

The course of work of the utility model plate tensile sample hydraulic clamp is as follows:

At first polylith plate tensile sample blank 8 is placed on the support plate 3, presses the clamping switch on the push-button station then, hydraulic oil then enters the hydraulic jack 7 from the oil-in of oil cylinder upper end or side, and promotion piston rod 6 moves downward, compress sample, then start milling cutter 8, sample is processed, after processing, press clamping switch again, this moment, hydraulic oil went up, and piston rod 6 extracts thereupon, clamp device loosens, and can take out the sample that processes.

Compare Yu prior art, the utlity model has following You point:

1. be frame type combined structure, simple in structure, good rigidly, clamping force is big.

2. You Yu adopts hydraulic clamp, loosens, and has the moving characteristics fast and safely of Zi.

3. the interlock of hydraulic oil piston rod Automatic-clamping or loosen sample, and Yu lathe realizes processing The automatic cycle of process has greatly alleviated workman's labour intensity.

4. the production efficiency height can satisfy the requirement of the timely inspection during manufacture of sample.
