Abstract
The invention belongs to an assembly tooling design technology and relates to a pressing rivet device used for a one-way valve shell assembly. The pressing rivet device is characterized in the pressing rivet device consists of a valve seat (3) and a pressure head (4), wherein a rectangular plate is arranged at the lower part of the valve seat (3); a cylinder is arranged in the center of the upper surface of the rectangular plate; a pressing rivet hole (3b) orthometric with the upper section hole of a stepped hole (3c) is formed in the midpoint of each of four edges of the rectangular plate. The pressing rivet device is capable of keeping the pressing rivet force uniform and preventing the pressure head from sliding, the consistency of a gap between a lower seat (1) and an upper cover (2) is ensured after pressing rivet assembly, and the percent of pass of the pressing rivet assembly is improved.
Description
Technical field
The invention belongs to assembly tooling designing technique, relate to a kind of pressure riveting device of check-valve body assembly.
Background technology
A kind of check-valve body assembly is made up of lower seat 1 and upper cover 2, and the external cylindrical surface of lower seat 1 has a cannelure, and the edge of upper cover 2 lower port is pressed in above-mentioned cannelure, and lower seat 1 and upper cover 2 are connected as one.Current riveting method is: by directly pressing with drift after manual compression.Its shortcoming is: in the process of pressing, and because the power of pressing is uneven, easily causes pressing assembling and descends the gap of seat 1 and upper cover 2 inconsistent afterwards, easily come off; And owing to being that arc surface presses, pressure head easily skids and causes part rejection.
Summary of the invention
The object of the invention is: propose a kind of can ensure the power of pressing evenly, the pressure riveting device of the check-valve body assembly of avoiding pressure head to skid so that the uniformity in lower seat 1 and upper cover 2 gap after the assembling that ensures to press, improve the qualification rate pressing and assemble.
Technical scheme of the present invention is: for the pressure riveting device of check-valve body assembly, be made up of lower seat 1 and upper cover 2 by the check-valve body assembly pressed, the external cylindrical surface of lower seat 1 has a cannelure, the edge of upper cover 2 lower port is pressed in above-mentioned cannelure, and lower seat 1 and upper cover 2 are connected as one; It is characterized in that: pressure riveting device is made up of valve seat 3 and pressure head 4, the bottom of valve seat 3 is rectangular slab, a cylinder is had at the center of this rectangular slab upper surface, the through rectangular slab of centre bore of cylinder, the centre bore of cylinder is stepped hole 3a, on this stepped hole 3a, the aperture of sector hole coordinates with by the crest clearance of check-valve body assembly pressed, and under this stepped hole 3a, the aperture of sector hole is less than sector hole, respectively has press a hole 3b orthogonal with the upper sector hole of stepped hole 3a at the mid point on four limits of rectangular slab; Pressure head 4 is rear end bearing pins with knurled knob, and the front end of pressure head 4 is conical, the external diameter of pressure head 4 optical axis portion and the hole 3b matched in clearance that presses; When in the stepped hole 3a being installed to valve seat 3 by the check-valve body assembly pressed, the lower surface of check-valve body assembly and the step end face laminating of stepped hole 3a, the cone point of pressure head 4 front end aims at the mid point of lower seat 1 cannelure groove width.
Advantage of the present invention is: propose a kind of can ensure the power of pressing evenly, avoid the pressure riveting device of the check-valve body assembly that pressure head skids, the uniformity in lower seat 1 and upper cover 2 gap after ensure that the assembling that presses, improves the qualification rate of the assembling that presses.One embodiment of the present of invention, prove through test, and the qualification rate of the assembling that presses improves more than 2 times than originally.

Detailed description of the invention
Below the present invention is described in further details.See Fig. 1,2, for the pressure riveting device of check-valve body assembly, be made up of lower seat 1 and upper cover 2 by the check-valve body assembly pressed, the external cylindrical surface of lower seat 1 has a cannelure, the edge of upper cover 2 lower port is pressed in above-mentioned cannelure, and lower seat 1 and upper cover 2 are connected as one; It is characterized in that: pressure riveting device is made up of valve seat 3 and pressure head 4, the bottom of valve seat 3 is rectangular slab, a cylinder is had at the center of this rectangular slab upper surface, the through rectangular slab of centre bore of cylinder, the centre bore of cylinder is stepped hole 3a, on this stepped hole 3a, the aperture of sector hole coordinates with by the crest clearance of check-valve body assembly pressed, and under this stepped hole 3a, the aperture of sector hole is less than sector hole, respectively has press a hole 3b orthogonal with the upper sector hole of stepped hole 3a at the mid point on four limits of rectangular slab; Pressure head 4 is rear end bearing pins with knurled knob, and the front end of pressure head 4 is conical, the external diameter of pressure head 4 optical axis portion and the hole 3b matched in clearance that presses; When in the stepped hole 3a being installed to valve seat 3 by the check-valve body assembly pressed, the lower surface of check-valve body assembly and the step end face laminating of stepped hole 3a, the cone point of pressure head 4 front end aims at the mid point of lower seat 1 cannelure groove width.
The operation principle of patent of the present invention is: be vertically positioned in the stepped hole 3a of pressure riveting device valve seat 3 by needing the check-valve body assembly pressed, the lower surface of check-valve body assembly and the step end face laminating of stepped hole 3a, two pressure heads 4 are put into two coaxial hole 3b that press, the cone point of pressure head 4 front end aims at the mid point of lower seat 1 cannelure groove width, pressure riveting device is clamped on vice, the knurled knob side end face of two pressure heads 4 is gently pressed by vice, the edge of upper cover 2 lower port of check-valve body assembly is made to produce inside distortion, reach the object pressed, again two pressure heads 4 are placed in two other coaxial hole 3b that presses of valve seat 3 and press.
