Abstract

The utility model relates to a clamp which processes shaft pieces with grooves at the outer circles on space angle planes symmetric with the grooves. The utility model comprises a bottom plate, a centre handle, a tail centre seat, a work-piece clamp, a Moh's mandrel, a clamp seat component, a regulating device and a dividing disc, wherein the dividing disc is arranged on the end face of the Moh's mandrel, and the outer end face of the dividing disc is provided with the work-piece clamp and the regulating device. The utility model cooperates with an ordinary grinder by mechanical repeated positioning, the regulating device is used to fine regulate the initial position of work-pieces, a dividing positioning device and the dividing disc are used to position various space planes, and then all the space angel planes on the outer circles of the pieces are sequentially processed. The utility model solves the problem that the ordinary grinder adopts ordinary methods to process the space angle planes on the outer circles of the shaft pieces, the processing accuracy requirements are hard to guarantee, and the efficiency is low. The clamp is simple in structure, accurate in positioning and able to effectively guarantee the processing requirements of each space angle plane.

Description

Processing space angle plane anchor clamps

Technical field:

The utility model relates to a kind of clamping tool for machine work, relate in particular to a kind of to trough of belt on the axial workpiece cylindrical, and with the anchor clamps of the space angle plane of groove symmetry processing.

Background technology:

In the processing of carrying out angle plane in space on the axial workpiece cylindrical on the general-purpose grinder, particularly to being with multiple-grooved on the axial workpiece cylindrical, and, adopt conventional method processing not only to be difficult to guarantee the requirement on machining accuracy of part and inefficiency with the processing on each space angle plane of groove symmetry.Though a kind of fully-automatic equipment to above-mentioned Machining of Shaft-type Parts is arranged now, but this equipment price is expensive especially, the Installation and Debugging complexity, require technical level of operators very high, and only be applicable to processing in enormous quantities, when changing processing dimension, adjust very difficulty, the space angle plane processing of the axial workpiece of incompatibility small lot or the frequent conversion of size.

Summary of the invention:

The purpose of this utility model is: employing machinery resetting a kind of and the general-purpose grinder adapted is provided, can disposablely machine on the various axial workpiece cylindricals and be with multiple-grooved, and each space angle plane with the groove symmetry, the location accurately, can effectively guarantee each space angle plane requirement, processing space angle plane anchor clamps simple to operate.

The utility model is to realize above-mentioned purpose by following technical solution:

These processing space angle plane anchor clamps are made up of base plate, top handle, tail centre seat, tail centre, Workpiece clamping head, Mohs mandrel, top, fixture head base member, indexing positioning device, adjusting device and index dial, one end of base plate is equipped with the tail centre seat, and top handle and tail centre are housed on the tail centre seat; The other end of base plate is equipped with the fixture head base member, and Mohs mandrel and top is housed in the fixture head base member; It is characterized in that: on the end face of Mohs mandrel index dial is housed, a side of index dial is equipped with indexing positioning device, and Workpiece clamping head and adjusting device are housed on the outer face of index dial.

The utility model beneficial effect compared with prior art is:

Can once be with a plurality of grooves on the property working shaft-like part cylindrical on the general-purpose grinder, and, can also rotate axial workpiece is carried out any five equilibrium angle or the processing of non-five equilibrium space angle plane with each space angle plane of groove symmetry; Simple in structure, economical and practical, the location accurately can effectively guarantee the processing request on each space angle plane.

The specific embodiment:

Referring to accompanying drawing 1-3, these processing space angle plane anchor clamps are by base plate 1, top handle 2, and tail centre seat 3, tail centre 4, Workpiece clamping head 5, Mohs mandrel 6, top 7, fixture head base member 8, indexing positioning device 9, adjusting device 10 and index dial 11 constitute.One end of base plate 1 is equipped with tail centre seat 3, and top handle 2 and tail centre 4 are housed on the tail centre seat 3; The other end of base plate 1 is equipped with fixture head base member 8, and Mohs mandrel 6 and top 7 are housed in the fixture head base member 8; Index dial 11 is housed on the end face of Mohs mandrel 6, and a side of index dial 11 is equipped with indexing positioning device 9, and Workpiece clamping head 5 and adjusting device 10 are housed on the outer face of index dial 11.

Before the work,, open tail centre seat 3 more earlier by Workpiece clamping head 5 clamping work pieces 12, workpiece 12 is put into anchor clamps, then top 7 and tail centre seat 3 just limited the axial freedom of workpiece, and Workpiece clamping head 5 and adjusting device 10 have limited the radially free degree of workpiece 12, then can carry out grinding.

Add man-hour, at first utilize the initial position of adjusting device 10 fine setting workpiece 12, utilize indexing positioning device 9 and index dial 11 to carry out each space plane location again, then can be successively with each space angle plane on the emery wheel 13 processing parts cylindricals, can fully guarantee the every precision in space angle plane on the axial workpiece cylindrical of workpiece 12.
