Abstract

The utility model discloses a milling machine clamp, and the milling machine clamp comprises a clamp body, V-shaped blocks, V-shaped block supporting parts, a locating shaft and a locking bolt, wherein the V-shaped block supporting parts are fixed at the upper end of the clamp body, a group of V-shaped blocks are installed in an inner side groove which is enclosed by the V-shaped block supporting parts, the locking bolt is connected with the clamp body and also one ends of the group of V-shaped blocks, and the locating shaft used for supporting workpieces is arranged on the clamp body. According to the milling machine clamp disclosed by the utility model, by adopting the V-shaped blocks to locate and clamp the workpieces, multiple workpieces are clamped simultaneously, the clamp structure is compact, and the operation is simple, convenient and reliable, thus saving the clamping time, shortening the designing and manufacturing period of the clamp, lowering the designing and manufacturing cost, weakening the labor intensity of workers, improving the production efficiency and ensuring the processing quality of parts.

Description

A kind of fraise jig

Technical field

The utility model belongs to the clamping tool for machine work technical field, is the fraise jig that a kind of Milling Process shaft-like workpiece end is used specifically.

Background technology

The Milling Process of shaft-like workpiece end, adopt the single-piece clamping mostly at present, and the clamping time is longer, and production efficiency is lower, and processing cost is higher.In case and the workpiece axial dimension needs when changing redesign to make fraise jig usually, increased the design and manufacture cost of fixture and produced the preparatory period; Simultaneously, existing axial workpiece end milling machine fixture operation is complicated, and labour intensity is large, and the workpiece crudy is relatively poor.

Summary of the invention

the problem that exists in order to overcome prior art, the purpose of this utility model is to provide a kind of many fraise jigs, clamping when this fraise jig is applicable to a plurality of shaft-like workpiece, adopt screw clamping mechanism, the location take V-block as setting element, adapt to the variation of workpiece axial dimension as adjustment part with locating shaft, V-block is the clamping element clamping work pieces, clamp structure is compact, simple to operation reliable, saved the clamping time, shortened the cycle that manufactures and designs of fixture, reduced the design and manufacture cost of fixture, reduced workman's labour intensity, greatly improved production efficiency, guaranteed the crudy of part.

The purpose of this utility model is achieved through the following technical solutions.

A kind of fraise jig, this fraise jig comprises clamp body, V-block, V-block supporting member, locating shaft and clamping screw, described V-block supporting member is fixed on the clamp body upper end, one group of V-block is installed in the inner side slot that the V-block supporting member surrounds, described clamping screw is connected with clamp body, and be connected with an end of described one group of V-block, be used for the locating shaft of supporting workpiece to be arranged on clamp body.

The mode that locating shaft is connected with clamp body can be: be provided with rectangular hole slot on clamp body, be fixed on clamp body by locking nut after rectangular hole slot is passed at described locating shaft two ends.

The outer end of further, tightly locking bolt is connected with the double threaded screw of spherical handle.

In the utility model, the upper-lower position of locating shaft and the axial dimension of workpiece are suitable.

In the utility model, clamp body is fixed on milling machine table by T-shaped bolt and directional bond.Be provided with directional bond on clamp body, directional bond adopts sunk screw to be connected to the bottom of clamp body.The V-block supporting member adopts screw to be connected with clamp body.Clamping screw adopts with clamp body and is threaded.Movable V-block is sleeved on the clamping screw end.Knob adopts with double threaded screw and is threaded.Workpiece clamps with V-block after locating on locating shaft, single face V-block and two-sided V-block with its lower surface and external cylindrical surface.

The utility model operation principle is:

At first according to the shaft-like workpiece diameter dimension of required processing, design the processing V-shaped piece; According to the axial dimension of the shaft-like workpiece of required processing, adjust the upper-lower position of locating shaft and also lock with locking nut.Then complete the location with lower surface and the external cylindrical surface of workpiece on locating shaft, V-block.Drive double threaded screw rotation by knob, make tie down screw promote V-block workpiece pressing successively left.After workpiece is completed processing, unscrew tie down screw, V-block is returned, workpiece unclamps, and can realize freely loading and unloading of workpiece.When the shaft-like workpiece axial dimension changes, need the upper-lower position of locating shaft is adjusted in advance.

The utility model can be realized the effective clamping of many of various shaft-like workpieces.Employing V-block location adopts V-block and V-block to clamp, and takes full advantage of the good characteristics of V-block centering, has eliminated due to the impact of workpiece positioning datum (excircle of workpiece) diameter error on the workpiece crudy; For the workpiece of different axial dimensions, the upper-lower position that only needs to regulate locating shaft can be realized the clamping to workpiece, thereby effectively reduces the design and manufacture cost of fixture and produce the preparatory period.

The utility model adopts V-block locating clip clamping of workpieces, realize many clampings simultaneously, clamp structure is compact, simple to operation reliable, saved the clamping time, shorten the cycle that manufactures and designs of fixture, reduced the design and manufacture cost of fixture, reduced workman's labour intensity, improve production efficiency, guaranteed the crudy of part.
