Abstract
The utility model discloses a clamp for a pneumatic grinding machine of a nozzle. The clamp comprises a sleeve, and a V-shaped block for locating the sleeve, wherein a mounting hole for loading a work-piece is horizontally and inwardly arranged on the sleeve from the center of one end; a plurality of clamping elements are annularly and uniformly arranged at the end part of the sleeve along the radial direction; the clamping elements are arranged on the sleeve in transmission; an arc surface matched with the work-piece is arranged at one end of each clamping element contacting the work-piece; the sleeve is located on the V-shaped block; the work-piece is arranged into the sleeve mounting hole; the sleeve is radically loading into the clamping element; the arc surface can play a role of locating the work-piece and can grind the periphery of the work-piece as the arc surface matched with the work-piece is arranged at the end part of the clamping element; the clamp is simple in working principle, convenient to operate, and suitable for a common worker; after being used for a period of time, the clamp can be corrected for reusing, and the clamp meets the requirements of a batch production line, reduces the production cost, more easily ensures the grinding precision of the work-piece and reduces the effect of an anthropic factor.
Description
Technical field
The utility model relates to atomizer and makes the field, relates in particular to a kind of anchor clamps that are used for the pneumatic grinding machine of atomizer.
Background technology
At present; Use pneumatic grinding machine that injector nozzle matching parts is added man-hour, the processing of chewing mesopore and the seat surface of cover is the crucial operation of comparison, generally is divided into corase grind mesopore, correct grinding mesopore, corase grind seat surface, this four procedure of correct grinding seat surface and processes; Wherein, seat surface is meant the interior sealing cone that has on the workpiece; Adding man-hour, needing to guarantee the axiality of mesopore and seat surface, guaranteeing that so how both axialities become a difficult problem that needs solution.Before underway hole and the seat surface processing, at first the cylindrical to workpiece grinds, and promptly at first guarantees the circularity of workpiece; This is to guarantee mesopore and coaxial prerequisite and the committed step of seat surface, and present practice is: workpiece is stepped up artificial hand-held mill on anchor clamps; Mill is enclosed within the workpiece periphery; Staff rotates mill, makes the inwall and workpiece mutual friction mutually of mill, reaches the grinding to workpiece.The shortcoming of this lapping mode is: because peripheral grinding belongs to fine finishining to workpiece; Above-mentioned lapping mode depends on workman's experience fully, and not only error is bigger, and scrappage is higher; Simultaneously can not be applicable to the common laborer, make production cost also rise thereupon.
The utility model content
The purpose of the utility model is to solve the problems of the technologies described above; A kind of anchor clamps that are used for the pneumatic grinding machine of atomizer are provided, and it can not only realize the location of workpiece is clamped, and can also grind the outer workpiece circumference; Improve the circularity of workpiece, have simple in structure, easy to operate advantage.
For reaching this purpose, the utility model adopts following technical scheme:
A kind of anchor clamps that are used for the pneumatic grinding machine of atomizer; Comprise sleeve; And the vee-block that is used for its location, on said sleeve, inwardly offer and be used to the workpiece mounting hole of packing into, and radial ringed some clamping elements are set evenly along it in the end of said sleeve by one of which end central horizontal; Said clamping element transmission is arranged on the said sleeve, and said clamping element contacts an end and has the arc surface that is complementary with workpiece with workpiece.
Preferably, said clamping element has three, and radially evenly is arranged on the said sleeve along sleeve.
Preferably, the transmission of said clamping element screw thread is arranged on the said sleeve so that said clamping element can along said sleeve radially through the screw thread transmission feeding.
Further; Said clamping element comprises screw, and said screw end is connected with pad, and said pad has the arc surface that is complementary with workpiece; Said screw has external screw thread; Said sleeve radially be complementary offer internal thread hole, said screw screws in the said screwed hole, realizes that through the screw thread transmission said pad is along the feeding of sleeve radial alignment.
Preferably, also be provided with spring between said screw and the said sleeve, and said spring housing is peripheral at said screw.
Preferably, between said screw and the said pad through being threaded.
The beneficial effect of the utility model: at first sleeve is positioned on the vee-block, again workpiece is packed in the installing hole of sleeve, radially be respectively charged into two clamping elements by sleeve; Because the clamping element end has the arc surface that is complementary with workpiece; Can play the effect of location workpiece, and can grind the workpiece periphery, and then the 3rd clamping element of packing into; Realization is to the clamping of workpiece, and workpiece is further ground.The operation principle of these anchor clamps is simple, easy to operate, can be applicable to the common laborer, when just anchor clamps itself are made, requires comparatively strict; And in use for some time, anchor clamps are proofreaied and correct, can come into operation again, can satisfy the production line of batch demand, reduced production cost; Adopt these anchor clamps that workpiece is ground simultaneously, obviously precision guarantees more easily, has reduced receiving artificial factor.
