Abstract

The utility model discloses a mechanical machining clamp, which can clamp pieces in a shaft class for carrying out key seat machining. The utility model is characterized in that a square frame body whose four sides are provided with a fixed plate is used as a body of the utility model, and the four sides can be used as a positioning benchmark all; the clamp head of the utility model is two V-shaped blocks arranged in the square frame body; the two V-shaped blocks are connected with guide rails on the two edge frames of the square frame body through V-shaped troughs on the two ends of the two V-shaped blocks; the upper and the lower edge frames of the square frame body respectively have a pair of sunk bolt holes and a set of screw bolts matched with the sunk bolt holes to exert force on the clamp head. The utility model can carry out next key seat processing when the utility model is turned by 90 DEG or 180 DEG together with a workpiece after the utility model carries out one time positioning machining for the workpiece. Thus, the utility model has convenient rotation and can exactly position. Besides, the utility model can carry out the processing of workpieces with a long shaft.

Description

Machining chuck
Generally to establish a pair of being advisable about every interval 5mm, controlling die opening certainly, to be up to the aperture minimum be a cover.
The utility model has the advantages that: owing to adopt four limits all to can be used as the square frame body of location benchmark as chuck body, therefore add man-hour at the workpiece that axle class part is carried out 180 ° of symmetries or 90 ° of vertical keyways, after having one-time positioning processing, only need anchor clamps can be carried out the processing of next keyway for 180 ° or 90 ° together with the workpiece upset; These anchor clamps not be owing to need withstand centre bore when holding workpiece, but have enlarged the scope of processing work again.Therefore, after this utility model had clamping, rotational angle was convenient, accurately and can carry out the characteristics such as processing of long axis workpiece.
Accompanying drawing and description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A view.
Among the figure: 1, be the anchor clamps framework, 2, fixed head, 3, upper grip, 4, dormant bolt, 5, the side frame of band V-way, 6, lower chuck, 7, screw, 8, bayonet socket.
Embodiment
Present embodiment is applicable to the processing diameter anchor clamps that axle class part uses in Φ 25~135mm scope.Two pairs in present embodiment one cover, its structure, size are all identical.Wherein:
Framework 1 each length of side is 250mm, the V-way tapering on the dual-side 5 be 27 ° of 30 ' fixed head 2(long * wide * thick) be 115 * 60 * 5mm, totally four, be symmetrically welded middle part respectively in four edges, the fastener hole of two Φ 123mm is respectively bored on both sides; Two countersunk head screws that cooperate with dormant bolt 4 on upper and lower frame are symmetrical arranged, and centre-to-centre spacing is 120mm, and counterbore is a cylindricality, screwhole diameter M8, counter bore hole diameters Φ 18mm, dark 15mm; Framework adopts weldering to form integral body, match grinding after heat treatment, and the opposite side depth of parallelism is 002mm, the perpendicularity on adjacent both sides is 003mm.Upper grip 3, the tapering of lower chuck 6 two ends dovetail grooves also adopt 27 ° 30 ', the wide 30mm of opening part is with leading on the dual-side 2 of framework 1
The utility model belongs to a kind of clamping tool for machine work, and particularly a kind of class part anchor clamps especially are suitable for vertical knee-type milling machine carries out keyway etc. to axle class part processing.
On lathes such as milling machine, various axle class parts are carried out keyway processing (comprising the processing of rectangular spline axle) at present, generally all adopt dividing head or flat-nose pliers as clamping device.Though adopt dividing head to have advantages such as angle adjustment is convenient, accurate, owing to its method of clamping is that the other end must withstand with thimble, so the length of workpiece is subjected to certain limitation, particularly is difficult to process for long-axle workpieces; And adopt the flat-nose pliers clamping, being used for processing vertical mutually, need first setting-out during multikeyways such as symmetry, in process, must carry out the centering debugging, therefore exist both time-consuming, efficient is low, is difficult to the disadvantage of ensuring the quality of products again.
The purpose of this utility model is: design and a kind ofly be mainly used in that axle class part is carried out 180 ° of symmetrical keyways, 90 ° of vertical keyways and keyway head number is the anchor clamps that the workpiece of 2-4 head is processed, to reach accurate positioning, convenience and can carry out purpose than the processing of farm labourer's part.
Solution of the present utility model is: the body of anchor clamps adopts four limits all to have fixed head and all can be used as the square frame body of locating surface, and chuck is two V-blocks being located in the framework, upper and lower two frames at the square frame body respectively are provided with the cover dormant bolt that a pair of dormant bolt hole reaches cooperation with it, at framework two inner side edges one V-way is arranged respectively: respectively there is a V-shaped groove at the V-block two ends as chuck, and flexibly connect and can relatively move by the V-way on this V-shaped groove and framework two inner side edges, to form chuck; Whole anchor clamps then are connected with workbench by arbitrary fixed head of being located at framework four limits, and by sunk screw chuck are imposed chucking power.As two V-blocks of chuck, the back side of a V-block is provided with two screws therein, overlaps dormant bolt by one of different length itself and framework are flexibly connected, and both has been convenient to the clamping of workpiece, can reduce the reserve level of bolt again.It is some right that dormant bolt one cover is divided into, the distance that its logarithm press the chuck opening and closing calmly, rail is slidingly matched; Bayonet socket 8 adopts the V-arrangement bayonet socket, the wide 34mm of oral area, and the screw 7 that tapering 27 30 is respectively attacked a M8 in the bottom of lower chuck 6 corresponding to the position of countersunk head screw, this screw is a blind hole, dark 15mm; Each dormant bolt 4 diameter is M8, and length is 40~115mm, and per two is a pair of, and length difference 5mm between the two adjacent groups adopts 35 #Steel, modifier treatment is to HRC22~27.Select corresponding two pairs of bolts (upper and lower each a pair of) for use according to be processed diameter during use; Clamp the back and it is anchored on the workbench, when processing next keyway anchor clamps are tightened up with workbench for 90 ° or 180 ° together with the workpiece upset again, get final product work by fixed head 2.
