Abstract
The invention discloses a special fixture for processing a cross groove. The fixture comprises a mounting base, wherein an inner cavity is formed in the mounting base; a fixture body for holding a workpiece is arranged in the inner cavity; four thread holes with the bottom surface of the inner cavity as center are evenly distributed in the periphery of the mounting base; the parts of the thread holes extending to the bottom surface of the inner cavity are lower half thread holes; upper half thread holes symmetrical with the lower half thread holes are formed in the bottom surface of the fixture body; and fixed bolts extending into the inner cavity to connect and fix the fixture body are connected into the thread holes. The fixture has no need to loosen and clamp the workpiece for many times in use, can conveniently process the cross groove with higher precision requirement on the workpiece through a mode of self rotation of the fixture body by 90 degrees, is quick and simple in clamping and adjustment, simplifies the operational process, improves the working efficiency, and is suitable for processing the cross groove with higher precision.
Description
Technical field
The present invention relates to a kind of cross recess Special Fixture for Machining.
Background technology
In machining, often run at workpiece end face or Surface Machining cross recess, namely simple processing method is by Work-sheet pressing, adopts the mode such as milling or planing, process a groove, then unclamp workpiece, by changing of workpieces to 90 degree, then clamping work pieces, process another groove perpendicular with last bar groove, form cross recess.This processing technology, during processing Article 2 groove clamping workpiece, angle correct need be carried out, before and after ensureing, groove becomes 90 degree, and operation comparatively bothers, and the workpiece not high for required precision can also meet the demands, if and the mutual vertical precision of cross recess requires higher, be difficult to meet required precision, and multiple clamping workpiece, operating efficiency is also lower.
Summary of the invention
The technical problem to be solved in the present invention is: the deficiency overcoming prior art, provides the cross recess Special Fixture for Machining that a kind of clamping is efficient and convenient, can ensure machining accuracy.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cross recess Special Fixture for Machining, comprise mounting seat, described mounting seat is provided with inner cavity, the clamp body of place work piece is equipped with in inner cavity, mounting seat circumference is laid with four screwed holes centered by inner cavity bottom surface, it is second screwed hole that screwed hole stretches into inner cavity bottom surface portions, clamp body bottom surface is provided with first screwed hole symmetrical with second screwed hole described, is connected with the set bolt stretching into inner cavity and be connected and fixed by clamp body in described screwed hole.
Further, at least three connecting screw holes that can be connected with pressure strip when circumference is laid with clamping workpiece on described clamp body.
The invention has the beneficial effects as follows: when the present invention uses without the need to repeatedly unclamping, clamping work pieces, 90 modes are rotated by clamp body self, the higher cross recess of required precision can be processed easily on workpiece, clamping adjustment is fast and convenient, simplify the operation flow process, increase work efficiency, the cross recess processing that applicable machining accuracy is higher uses.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of cross recess Special Fixture for Machining as shown in Figure 1 and Figure 2, comprise mounting seat 1, described mounting seat 1 center offers inner cavity 11, the clamp body 2 of place work piece is equipped with, three connecting screw holes 21 that can be connected with pressure strip when circumference is laid with clamping workpiece on described clamp body 2 in inner cavity 11.
Four screwed holes 12 are laid with in mounting seat 1 circumference, the center line of described screwed hole overlaps with inner cavity 11 bottom surface, the bottom surface portions that screwed hole 12 extend into inner cavity 11 forms second screwed hole, clamp body 2 bottom surface is provided with first screwed hole symmetrical with second screwed hole described, second screwed hole and first screwed hole form a complete screw identical with screwed hole 12, the processing of second screwed hole and first screwed hole, after clamp body 2 is placed in inner cavity 11, when thread mill drilling 12, disposable machining obtains, ensure the screw that the involutory rear formation of second screwed hole and first screwed hole is identical with screwed hole 12, the set bolt 3 stretching into inner cavity 11 and be connected and fixed by clamp body 2 is connected with in described screwed hole 12.
During use, workpiece is placed on clamp body 2, connecting screw hole 21 is screwed into by Work-sheet pressing by pressure strip with bolt, then being coordinated by clamp body 2 is installed in the inner cavity 11 of mounting seat 1, adjustment clamp body 2 position, ensure that second screwed hole on inner cavity 11 overlaps into complete screw with first screwed hole on clamp body 2, be screwed into set bolt 3 clamp body 2 is fixed, on workpiece, flat recess is processed by milling or planing mode, completion of processing, unclamp set bolt 3, by clamp body 2 90-degree rotation, again clamp body 2 is fixed by preceding method, process the Article 2 flat recess perpendicular with manufactured flat recess, article two, flat recess forms a complete cross recess.The special fixture of this structure, clamping is fast and convenient, and not only workpiece is without the need to multiple clamping, and simplify the operation flow process, increases work efficiency, and can fully ensure cross recessed machining accuracy, and the cross recess processing that applicable machining accuracy is higher uses.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
