Abstract
The utility model discloses a polygonal quick grinding clamp. The utility model comprises a clamp body, wherein a straight hole which is arranged in the clamp body is communicated with a taper hole, one end of the clamp body is provided with a locking nut, a spring chuck is sheathed in the straight hole and the taper hole of the clamp body, and the clamp body forms a polygon. The exterior shape of the spring chuck is divided into a straight section part and a cone section part, the middle of the spring chuck is provided with an elastically contracting spring, the straight section part of the spring chuck is sheathed in the straight hole of the clamp body, and the cone section part is sheathed in the taper hole. Because the utility model is sheathed with the spring chuck on the original clamp body, parts with different outside dimensions can be clamped and ground, work efficiency is enhanced, use ranges are enlarged, labor intensity is reduced, and the utility model is easy to operate and master.
Description
Technical field
The utility model relates to field of machining, and being used for the cylindrical is the regular polygon of location benchmark or the grinding anchor clamps of non-regular polygon part, particularly a kind of polygon rapid stock-removal anchor clamps.
Prior art
In machining, to do polygon processing at cylinder one end, boss is processed, and the processing of trough is mainly finished by milling machine processing stock removal, and the frock of control machining shape is dividing head or disk indexing fixture.Because the structure and the precision of these two kinds of anchor clamps are only applicable to the milling machine semifinishing, are not suitable for grinding.
The grinding aspect, this polygonal part boss, groove class part often adopts special-purpose clamp, to be six sides at Φ 10 cylinders one end is example, when locating hole is standard Φ 10 (locating holes in six side's anchor clamps), if in limited time for 10.01 of Φ can not insert the unable processing of locating hole, 9.99 insertion locating holes then produce 0.01 gap to cylinder Φ 10 tolerances if the cylinder size is Φ when allowance below nominal size last.If will process it then needs several six side's clamp body locating holes to satisfy processing request, then need a large amount of clamp bodies finish processing as if processing Φ 5, Φ 6 or Φ N.
Make the location benchmark of circle with 90 ° of V shape iron troughs and process, the setting circle outside dimension is not had strict demand also can accomplish grinding very accurately, but must dispose sinusoidal anchor clamps grinding, since V shape iron appearance and size accuracy height, vertical parallel symmetry height.By certain calculating, just can guarantee its requirement with precision gage block and amesdial, though can process, efficient is low, not easy to operate and grasp; Specificity is too strong, can not change because of outside dimension; Do not influence when outside dimension changes that to add man-hour its method just too complicated, to need simultaneously to calculate, to use frock too many, it is big to measure clamping proof-reading amount, and efficient is low, is difficult for promoting the use of.
Summary of the invention
The purpose of this utility model is to provide a kind of polygon rapid stock-removal anchor clamps, and it is simple to operation, has reduced complicated calculating and measurement, reduces the work processing cost.
The technical solution of the utility model is achieved in that the utility model comprises clamp body, is provided with straight hole in the clamp body, and straight hole is connected with taper hole, and an end of clamp body disposes locking nut, is with collet in the straight hole of clamp body and taper hole.
Clamp body is a polygon.
The collet outer shape is divided into straight section portion and awl section portion, in the middle of it elastic shrinkage spring is set, and the straight section portion of collet is enclosed within the straight hole of clamp body, and awl section portion is enclosed within the taper hole.
Clip polygon is concrete only to need one, and size can just can satisfy requirement on machining accuracy by definite or simple guide pin bushing head according to the size (as Φ 3 to Φ 19) of clamp head, has saved production cost.
The utility model since on original clamp body suit collet, can carry out the clamping grinding to the part of various outer diameter size, improved operating efficiency, enlarged the scope of application, reduced labour intensity, grasp easy to operate.
Description of drawings
Fig. 1 is a fractionation section of structure of the present utility model;
Fig. 2 is a structural representation profile of the present utility model;
Below in conjunction with accompanying drawing content of the present utility model is described further.
The specific embodiment
With reference to Fig. 1, shown in Figure 2, polygon rapid stock-removal anchor clamps comprise clamp body 1, and the bottom is a straight hole 4 in the clamp body 1, straight hole 4 UNICOM's taper holes 5, and an end of clamp body 1 can be equipped with locking nut 3 by screw thread, in clamp body 1 internal sleeve collet 2 is housed.Clamp body 1 is a polygon.Collet 2 outer shape are divided into straight section portion 6 and awl section portion 8, in the middle of it elastic shrinkage spring 7 are set, and the straight section portion 6 of collet 2 is enclosed within the straight hole 4 of clamp body 1, and awl section portion 8 is enclosed within the taper hole 5.Part 9 passes elastic shrinkage spring 7 mesopores in the collet 2, and straight hole 4 in clamp body 1, and locking nut is screwed on the clamp body 1.
The course of work of the present utility model is as follows:
Level is used, vertical use all must be selected the polygonal shape clamp body according to the requirement of shape; Confirm location external diameter selection respective springs chuck 2; Clean the locating hole and the conical surface on the clamp body 1, the collet of having wiped 2 is inserted clamp body 1.To be ground part positioning and clamping end again and clean, in the hole of the corresponding collet 2 interior elastic shrinkage springs 7 of packing into, upper locking nut 3; Adjust the parallel angle relation that levelling is ground face and clamp body 1, inspection is ground the allowance of face, tightens locking nut 3 after qualified; The direction relations of gauging fixture body 1 and table positions face carries out grinding after the affirmation.
When level is used, make clamp body 1 axial centre parallel, can do the polygon grinding, also can do right cylinder, the grinding of different in nature post in the shaft parts direction with workbench;
During vertical the use, make clamp body 1 longitudinal center line, the cylinder end surface shape is carried out grinding perpendicular to workbench;
Level, when vertically using simultaneously, same part by one-step clamping had both been done the grinding of axial external diameter direction also the mixing that end face carries out grinding had been used.
With collet 2 clamp body 1 of packing into, tighten locking nut 3, they are used, play compression collet 2, can be fixedly clamped simultaneously is ground the effect of part, locking nut 3 combines with the external screw thread of clamp body 1.
