Abstract
The invention discloses an overall riveting process of a linear stapler. The overall riveting process of the linear stapler includes adjusting a hydraulic machine according to process parameters, sequentially assembling parts of a rivet abutting base lower holding plate, a rivet abutting base assembly, a component holding plate assembly, a positioning rod pushing plate, a rivet abutting base rivet, a holding plate rivet, an upper limiting plate, a lower limiting plate, a limiting plate tension spring, a reset button, a reset button spring, a reset button rivet, a movable handle assembly and a rivet abutting base upper holding plate into a riveting die according to an assembling process, positioning the parts with a positioning device of the riveting die, starting the hydraulic machine, riveting all rivets for one step, and assembling and shaping the parts according to the riveting die. The overall riveting process of the linear stapler utilizes the riveting die for accurate positioning, and all the rivets are riveted by a machine for one step, so that the product assembly accuracy is greatly improved, the yield of products is improved, and time is saved.
Description
Technical field
The present invention relates to linear anastomat field, particularly relate to the overall riveting process of a kind of linear anastomat.
Background technology
Straight line kiss (seam) closes device, is again straight line closer.Tissue can be carried out linear suture by this stitching unstrument.Applicable specification is reserved in advance according to tissue thickness during use, tissue is placed between nail bin and resist-nailed seat, place pilot pin, pull firing handle, staple driver is about to the staggered staple implanting tissue of two rows and bends to " B " shape, the same with stapler principle, two layers of tissue stitching is closed securely.This stitching unstrument not belt cutter, therefore without cutting function.
Existing apparatus shape, mainly for satisfied operation needs, can be born the straight line force of pushing direction when suturing nail is shaped, but structure can not bear cross force.If contraposition is not just when nail bin and resist-nailed seat assemble, is producing transverse component during percussion, will the shaping of suturing nail had a strong impact on, and even may cause operative failure.Existing manual rivet assembly precision is poor, and yield rate is low, expends man-hour.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the overall riveting process of a kind of linear anastomat, and adopt mould accurately to locate, all rivets once riveted by machine, greatly can improve the assembly precision of product, improve product percent of pass, save man-hour.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of linear anastomat overall riveting process, comprise the following steps: first that hydraulic press is good according to technical arrangement plan, product component resist-nailed seat lower plate, resist-nailed seat assembly, assembly clamping plate assembly, backstay push pedal, resist-nailed seat rivet, clamping plate rivet, upper limit plate, lower limiting board, limiting plate extension spring, SR, SR spring, SR rivet, flexible handle assembly and resist-nailed seat train wheel bridge load riveting die set successively by assemble sequence, with the positioner on riveting die set by each position components, locate rear startup hydraulic press, whole rivet is once riveted, make parts by riveting die set assembling sizing.
In a preferred embodiment of the present invention, described riveting die set comprises framed, guide pillar, locating dowel, red needle, red needle push pedal and spring up and down, described framed be up and down isolating construction, located by guide pillar during matched moulds, described red needle is arranged in red needle push pedal, penetrates in the framed upper hole consistent with rivet location, described locating dowel be arranged on framed on, described spring fitting red needle push pedal and framed between, play reset role.
The invention has the beneficial effects as follows: the present invention adopts mould accurately to locate, all rivets once riveted by machine, greatly can improve the assembly precision of product, improve product percent of pass, save man-hour.
