Description

A kind of practical clamp for grinding

Technical field

The utility model relates to technical field of mechanical processing, especially a kind of practical clamp for grinding.

Background technique

Contour column is commonly used a kind of machine components in Automatic manual transmission manufacture, it is required that the multiple contour columns used simultaneously Height dimension it is consistent.In the processing of contour column, lathe process outer dimension is often first used, and in the axial direction of contour column Grinding allowance is reserved in (height) direction, then the axial dimension of multiple contour columns is worked into the ruler of drawing requirement simultaneously using grinding machine It is very little.However, the high column grinding such as some lesser axis classes of diameter is more difficult in the actual manufacturing, it is main to show : (1) its diameter smaller, small with the contact area of grinding machine, and grinding machine electromagnetic disc leads to the shifting of contour column to its limited sorption capacity It is dynamic, cause safety accident；(2) height dimension of multiple contour columns is difficult to ensure that consistency, machining accuracy are low.It is asked for this Topic, my company propose Authorization Notice No. are as follows: a kind of " the contour column clamp " of CN207402645U efficiently solves Problem is stated, but there is also the quantity of fixed workpiece is few, the problems such as the heavier-weight of fixture.Meanwhile fastening screw is easy to make At the impression of workpiece surface, the presentation quality of workpiece is influenced.

Utility model content

The problem of purpose of the utility model is to solve above-mentioned background techniques provides a kind of practical grinding Clamp for machining, by the Curve guide impeller of fixture, dislocation is provided with inside and outside two exhausting hole, can grip more workpiece simultaneously, Utilization rate is improved, and fretwork area is big, alleviates the weight of fixture, it is easy to use.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of practical clamp for grinding, packet Chuck body is included, inside and outside two exhausting holes have been shifted to install in the upper and lower ends of the chuck body, in the chuck body Left and right ends are also equipped with the through-hole, and the side of the chuck body is provided with multiple fastening thread holes, the fastening spiral shell Pit is connected to one by one with the through-hole, and fastening screw, and the screw thread on the fastening screw are provided in the fastening thread hole Length dimension is bigger than the depth dimensions of the fastening thread hole.The through-hole is used for the placement of contour column (workpiece), the fastening Threaded hole and the fastening screw are used for the fixation of contour column, and multiple contour columns are connected in one, increasing section product, convenient for mill The absorption of bed magnechuck, improves safety in utilization and production efficiency.Simultaneously as using the inside and outside two rows through-hole, energy More contour columns are gripped simultaneously, are improved utilization rate, and fretwork area is big, are alleviated the weight of fixture, user Just.

Further, the inner end rotation of the fastening screw is connected with the brass pressure head of V-type, and the fastening screw is avoided to make At the impression of workpiece surface, the presentation quality of workpiece is influenced.

Further, the axis of the fastening screw is directed toward the center of circle of the through-hole, it is ensured that when in use, contour column stress Uniformly, it is firm to fasten.

The design principle of the utility model is: multiple contour columns being fixed in chuck body using multiple through-holes, are increased The contact area of contour column and electromagnetic chuck of grinder improves safety in utilization convenient for the absorption of electromagnetic chuck of grinder；Meanwhile Contour column is connected in one with chuck body, convenient for the grinding of two end faces above and below contour column, improves machining accuracy.

The beneficial effects of the utility model are: dislocation is provided with inside and outside two exhausting hole by the Curve guide impeller of fixture, it can be same When grip more workpiece, improve utilization rate, and fretwork area is big, alleviate the weight of fixture, it is easy to use.

Specific embodiment

The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram, Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.

A kind of practical clamp for grinding shown in Fig. 1 to Fig. 4, including chuck body 1, in the chuck body 1 Upper and lower ends have shifted to install inside and outside two exhausting holes 2, are also equipped with the through-hole 2 in the left and right ends of the chuck body 1, The side of the chuck body 1 is provided with multiple fastening thread holes 3, the fastening thread hole 3 connects one by one with the through-hole 2 It is logical, fastening screw 4 is provided in the fastening thread hole 3, and the reach size on the fastening screw 4 is than the fastening The depth dimensions of threaded hole 3 are big.The through-hole 2 is used for the placement of contour column 6, the fastening thread hole 3 and the fastening screw 4 For the fixation of contour column 6, multiple contour columns 6 are connected in one, increasing section product, convenient for the absorption of electromagnetic chuck of grinder, Safety in utilization is improved, while also greatly improving production efficiency.Further, due to using the inside and outside two rows through-hole 2, More contour columns 6 can be gripped simultaneously, utilization rate is improved, and fretwork area is big, alleviates the weight of fixture, used It is convenient.

The inner end rotation of the fastening screw 4 is connected with the brass pressure head 5 of V-type, avoids the fastening screw 4 from causing contour The impression on 6 surface of column, influences the presentation quality of workpiece.

The axis of the fastening screw 4 is directed toward the center of circle of the through-hole 2, it is ensured that when in use, contour 6 uniform force of column, It is firm to fasten.

The diameter of the through-hole 2 is consistent, convenient for the placement and fastening of the same high column 6 of multiple same specifications, can be ground simultaneously Processing is cut, improves production efficiency, it is ensured that multiple contour 6 high consistencies of column.

As shown in Figure 2 and Figure 4, when in use, multiple contour columns 6 are inserted into through-hole 2, and fastening screw 4 is screwed, pressed First 5 phase is butted on contour column 6, and contour column 6 is connected in one with chuck body 1 at this time.Chuck body 1 is put into the electromagnetism of grinding machine again On sucker, it is ground an end face of contour column 6, after the completion of multiple contour columns 6 are ground, then by 1 turn-over of chuck body, is carried out The grinding of contour 6 another end face of column after being ground to the size of drawing requirement, that is, completes the grinding of contour column 6.

The utility model can grip more workpiece simultaneously, improve utilization rate, and fretwork area is big, alleviate The weight of fixture avoids workpiece surface from forming impression, influences the presentation quality of workpiece.

It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims Property range.
