Abstract
The invention relates to an inner hole turning auxiliary fixture for the cylinder body of a hydraulic cylinder. The inner hole turning auxiliary fixture comprises a mounting seat, wherein a positioning disk is arranged above the mounting seat through a rotating pair; a fixing barrel is welded in the center of the positioning disk; a centering frustum is arranged in the fixing barrel, and is welded in the center of the positioning disk; three clamping threaded barrels are fixedly welded on the outer edge of the upper end of the positioning barrel; butterfly-shaped studs are arranged in the clamping threaded barrels in a threaded connection way; the tail ends of the butterfly-shaped studs are fixedly connected with clamping heads. By adopting the inner hole turning auxiliary fixture, plastic deformation in a machining process is reduced, the accuracy of a machined step thread is increased, and the overall product yield is increased.
Description
Technical field
The present invention relates to clamping tool for machine work field, specifically hydraulic cylinder body endoporus turning auxiliary clamp.
Background technology
In the process of hydraulic cylinder, hydraulic cylinder body both sides endoporus needs step of turning, and in both sides cutted thread, for end cap and other seal members are installed.Turning process generally uses scroll chuck automatically to clamp, but because turning is difficult to ensure that cylinder body inner and outer round surface is coaxial, produces accumulated error at processing step or screw thread, and substandard product is increased.Particularly, in screw thread process, scroll chuck can only clamp one end, and processed end and bare terminal end span are larger, and process, due to plastic deformation, causes screw thread working depth more shallow, can not meet instructions for use.
For addressing the above problem, ad hoc this device of meter.Adopt in this device process, this device can be installed on machine tool three-jaw chuck, this fixture is tubular, utilize 3 clamping head threaded adjusting of this fixture one side circle distribution, find hydraulic cylinder body inner circle axle center accurately, itself and lathe pivot are remained in certain axiality, because clip position is near processing end, therefore the plastic deformation in process reduces, and the step processing also screw thread is more accurate, and product overall acceptability rate is improved.
Summary of the invention
The problem existing in order to solve above-mentioned prior art, the invention provides a kind of hydraulic cylinder body endoporus turning auxiliary clamp, the clip position of processed hydraulic cylinder can be held near processing, thereby be improved precision.
The present invention addresses the above problem adopted technical scheme:
Hydraulic cylinder body endoporus turning auxiliary clamp, comprises mount pad, and described mount pad top is provided with positioning disk by revolute; Described positioning disk center is welded with stationary magazine creel; In described stationary magazine creel, be provided with centering frustum, its centering frustum is welded on positioning disk center; Described positioning tube upper end outer rim is fixedly welded with three and clamps barrel; The mode being threaded connection in described clamping barrel is all provided with butterfly double-screw bolt; Described butterfly double-screw bolt end is fixed with clamping head.
Wherein, three described clamping barrels are evenly distributed on positioning tube circumference, and adjacent both are mutually 120 degree angles.
The invention has the beneficial effects as follows: hydraulic cylinder body endoporus turning auxiliary clamp, reduce the plastic deformation in process, improve the step accuracy of thread processing, product overall acceptability rate is improved.

Detailed description of the invention
As depicted in figs. 1 and 2, hydraulic cylinder body endoporus turning auxiliary clamp, comprises mount pad 1, and described mount pad 1 top is provided with positioning disk 2 by revolute; Described positioning disk 2 centers are welded with stationary magazine creel 3; In described stationary magazine creel 3, be provided with centering frustum 4, its centering frustum 4 is welded on positioning disk 2 centers; Described positioning tube 3 upper end outer rims are fixedly welded with three and clamp barrel 5; The mode being threaded connection in described clamping barrel 5 is all provided with butterfly double-screw bolt 6; Described butterfly double-screw bolt 6 ends are fixed with clamping head 7.
In the present embodiment, three described clamping barrels 5 are evenly distributed on positioning tube 3 circumference, and adjacent both are mutually 120 degree angles.
Use in the process of this device, first the mount pad of this device is clamped on machine tool three-jaw chuck, the hydraulic cylinder body of needs processing is put into stationary magazine creel inside, and the bottom of hydraulic cylinder body is enclosed within on centering frustum, make hydraulic cylinder body bottom center location.Utilize 3 clamping head threaded adjusting and the amesdial of this fixture one side circle distribution, find hydraulic cylinder body inner circle axle center accurately, itself and lathe pivot are remained in certain axiality, can process.Because clip position is near processing end, therefore the plastic deformation in process reduces, and the step processing also screw thread is more accurate, and product overall acceptability rate is improved.
More than show and described general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
Claims (2)
