Abstract

The utility model provides a spring retainer feeding rail of an engine locking dog screening machine. The feeding rail has U-shaped section, and upper end surfaces on two sides of the U-shaped rail are sunken to form symmetrical steps contacting with large ends of spring retainers. Groove with V-shaped sections are arranged along the length direction of the steps. A pair of parallel ribs extending along the length of the rail is formed from the top ends of the openings of the V-shaped grooves on the steps to the U-shaped groove surface, thereby forming a linear contact structure between the spring retainers and the conveying rail. As the contact mode between the spring retainers and the rail is changed into linear contact from surface contact, the contact area is reduced and then the conveying friction resistance is reduced. When in high-frequency vibration, the rail can vibrate synchronously to generate higher conveying force, so that blocking of conveying can be avoided completely.

Description

A kind of spring perch feeding track of driving engine lock dog screening machine

Technical field

The utility model relates to the apparatus field that shakes conveying products, especially in the driving engine assembling to the vibrations load transfer device of valve-spring retainer.

Background technology

Behind high-frequency vibration lock dog matching machine apolegamy lock dog and spring perch, need lock dog and spring perch be transported away by feeding track.Existing feeding track 1 as shown in Figure 1, its cross section is a U-shaped, sink to being symmetrically formed respectively in the upper surface of the dual-side of U-shaped one with the step of the big end in contact of spring perch, this step is a plane, makes that thus the big end of spring perch and its are that face contacts, and transporting resistance is bigger, in the course of conveying, portioned product is carried on delivery track and is produced clamping stagnation, and it is bad to cause delivery track to squeeze, and production can not be carried out.

Summary of the invention

The utility model has solved and has shaken the technical matters that the feeding friction force causes the feeding clamping stagnation greatly, and a kind of spring perch feeding track that transmits unimpeded lock dog screening machine is provided.

Technical solutions of the utility model are as follows:

A kind of spring perch feeding track of driving engine lock dog screening machine, described feeding track cross section is a U-shaped, sink to being symmetrically formed respectively in the upper surface of the dual-side of U-shaped one with the step of the big end in contact of spring perch; It is characterized in that offer a groove along the length direction of described step, the cross sectional shape of this groove is a V-arrangement.

Further, the peristome top of the V-shaped groove on described step forms the line contact structures of spring perch and delivery track to the parallel edge of U-lag face formation pair of tracks length direction.

The advantage of this track is as follows:

The way of contact of spring perch and track contacted by face change to line contact, reduce area of contact, thereby reduce to transmit friction drag, track keeps vibrations synchronously during high-frequency vibration, produces bigger conveying capacity, can solve the clamping stagnation problem of transmitting fully.

Description of drawings

Fig. 1 is the spring perch feeding track structural representation of prior art lock dog screening machine;

Fig. 2 is a structural representation of the present utility model

The specific embodiment

Referring to Fig. 2, this feeding track 2 adopts corrosion-resistant steel, the cross section is a U-shaped, upper surface at dual-side sinks to forming respectively a step 21, length direction along described step offers a groove 22, and the cross sectional shape of this groove is a V-arrangement, and the peristome top of V-shaped groove forms the parallel edge 23 of pair of tracks length direction to the U-lag face, the big end of described spring perch 3 is placed on the formed parallel edge 23, forms spring perch and conveyor track diatom contacting structure.

This feeding track 2 is connected on the vibrations feeder, and spring perch 3 is placed in orbit, and spring perch is a circular ladder rotary part, and electromagnetic shaker is opened, and produces carrying capacity the spring perch direction along ng a path is carried.Compare with Fig. 1, the contact surface that has changed delivery track and spring perch connects, and has reduced transporting resistance, and the fine conveying clamping stagnation problem that solved improves transport efficiency.

Claims

1. the spring perch feeding track of a driving engine lock dog screening machine, described feeding track cross section is a U-shaped, sink to being symmetrically formed respectively in the upper surface of the dual-side of U-shaped one with the step of the big end in contact of spring perch; It is characterized in that offer a groove along the length direction of described step, the cross sectional shape of this groove is a V-arrangement.

2. the spring perch feeding track of driving engine lock dog screening machine according to claim 1, it is characterized in that: the peristome top of the V-shaped groove on the described step forms the line contact structures of spring perch and delivery track to the parallel edge of U-lag face formation pair of tracks length direction.
