Abstract
The invention provides a grinding and clamping tool used for a tube spring of an electro hydraulic servo-valve. The tube spring is provided with a bore; the grinding and clamping tool comprises a mandril, a spacer sleeve and a nut, wherein the mandril is a T-shaped rod, and the diameter of a vertical rod of the mandril is matched with the bore of the tube spring, the length of the vertical rod is larger than that of the tube spring, and a thread is arranged on the external surface of the head part of the vertical rod; the tube spring is sleeved on the mandril, and the lower end surface of the tube spring is supported against the surface of a horizontal rod of the mandril; the spacer sleeve is sleeved on the mandril, and the lower end surface of the spacer sleeve is supported against the upper end surface of the tube spring; and the nut and the head part of the mandril are in threaded connection and are positioned on the upper end surface of the spacer sleeve, so that the spacer sleeve clamps the tube spring tightly in the axial direction. The grinding and clamping tool has the advantages of good operability, high processing accuracy, good repeatability and long service life, greatly reduces workload for processing, and greatly improves efficiency of production and processing.
Description
Technical field
The present invention relates to a kind of tools for processing and loading clamp, be specifically related to a kind of grinding and clamping tool that is used for the pipe spring of electrohydraulic servo valve.
Technical background
Electrohydraulic servo valve is a kind of high accuracy that is used for electrohydraulic control system, the electro-hydraulic servo control assembly with very high dynamic response, and it can be used for the hydraulic control system of accurate displacement, speed, power and acceleration.Pipe spring 1 (as shown in Figure 1) is the strength member of the key in the nozzle flapper electrohydraulic servo valve, it has that volume is little, size and the high characteristics of form and position tolerance precision, it is a flexible member, the thickness of its thin-walled 10 is about 0.06mm, not only want bearing certain pressure, and require left and right sides rigidity symmetry, and rigidity is definite value, so pipe spring 1 requires thin-walled 10 thickness even, can not there be any slight scuffing on inside and outside surface, the fillet place that two ends connect should be smooth, correct, and it is the key position of pipe spring 1.Being used to manage the spring processing method at present is: after first pipe spring car is good, and last grinding machine cylindrical.Because of the pipe spring thin-walled thinner, it is big to add the man-hour stress deformation, the back difficult specification requirement that reaches of processing, cause bigger defective products, the bourdon tube process technology requires to need the workload of grinding big, to having relatively high expectations of production work personnel than higher simultaneously, so that inefficiency, processing cost increase, and need to consume the great amount of manpower resource.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of grinding and clamping tool that is used for the pipe spring of electrohydraulic servo valve is provided, its operability is good, machining accuracy height, good reproducibility, long service life.
The technical scheme that realizes above-mentioned purpose is: a kind of grinding and clamping tool that is used for the pipe spring of electrohydraulic servo valve, and described pipe spring has an endoporus, and described grinding and clamping tool comprises a mandrel, an interstage sleeve and a nut, wherein,
Described mandrel is a T shape bar, and the diameter of its vertical bar mates with the endoporus of pipe spring, and the length of this vertical bar is greater than the length of managing spring and be provided with screw thread on the head outer surface;
Described pipe spring housing is contained on the mandrel and its lower surface is resisted against on the horizon bar surface of mandrel;
Described interstage sleeve is sleeved on the mandrel and its lower surface is resisted against on the upper surface of pipe spring;
Described nut and the head threads of mandrel are connected and are positioned at the upper surface of interstage sleeve, so that interstage sleeve pinch tube spring in the axial direction.
Above-mentioned a kind of grinding and clamping tool that is used for the pipe spring of electrohydraulic servo valve, wherein, described nut is a hex nut.
The beneficial effect of the grinding and clamping tool of the pipe spring that is used for electrohydraulic servo valve of the present invention is: will manage spring housing at mandrel, and simple to operate, easy to process, can reduce the great amount of manpower work, cut down finished cost, can guarantee machining accuracy simultaneously.
Description of drawings
Fig. 1 is the structural representation of the pipe spring of grinding and clamping tool clamping of the present invention;
Fig. 2 is the user mode figure of the grinding and clamping tool of the pipe spring that is used for electrohydraulic servo valve of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
See also Fig. 1 and Fig. 2, the pipe spring 1 of electrohydraulic servo valve has been shown among Fig. 1, this pipe spring 1 has an endoporus 11.
The grinding and clamping tool that is used for the pipe spring of electrohydraulic servo valve of the present invention comprises a mandrel 21, an interstage sleeve 22 and a nut 23, wherein, mandrel 21 is a T shape bar, the diameter of its vertical bar 211 mates with the endoporus 11 of pipe spring 1, and the length of this vertical bar 211 is greater than the length of managing spring 1 and be provided with screw thread on the head outer surface; Pipe spring 1 is sleeved on the mandrel 21 and its lower surface is resisted against on horizon bar 212 surfaces of mandrel; Interstage sleeve 22 is sleeved on the mandrel 21 and its lower surface is resisted against on the upper surface of pipe spring 1; Nut 23 is a hex nut, and it is connected and is positioned at the upper surface of interstage sleeve 22 with the head threads of mandrel 21, so that interstage sleeve 22 is at axial direction pinch tube spring 1.
Mandrel 1 is for being used for the endoporus 11 of stay pipe spring, after pipe spring 1 is sleeved on mandrel 21, can improve the processing rigidity of pipe spring 1 during grinding pipe spring 1, guaranteeing that pipe spring 1 thin-walled 10 can not be out of shape under wheel grinding, is the axiality that the machining benchmark processing excircles can guarantee to manage spring 1 with pipe spring 1 endoporus 11 simultaneously.
Above embodiment is only for the usefulness that the present invention is described, but not limiting the scope of the invention.Relevant those skilled in the art under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, and the technical scheme that all are equal to also should belong within the category of the present invention's protection, is limited by each claim.
