Problems solved by technology

[0002] In mechanical transmission, it is very common to transmit power and motion through the rod system. The conversion mode of the connection between the rods among the three rods known to be parallel to each other and reciprocating in the axial direction is realized by changing the number of teeth of the gear or sprocket. , this conversion has many defects, such as complex structure, high manufacturing cost, multiple transmission pairs and low efficiency, large volume and difficult layout, etc.

Embodiment Construction

[0013] exist figure 1 , figure 2 , image 3 Middle: including frame mechanism and conversion mechanism. The frame mechanism includes end cover 10, support sleeve 11, bolt 12, spring washer 16 and nut 4. There are two end covers 10 with the same shape, placed on both sides, with three supports in between Cover 11, the support sleeve 11 is the bolt 12, the bolt 12, the spring washer 16 and the nut 4 connect the end cover 10 and the support sleeve 11 into a fixed frame mechanism; the conversion mechanism includes a rod I5, a rod II9, a rod III13, and a connecting bump 6. Connection concave block 8, connection groove 7, positioning pin 1, washer 2, fixing pin 14; three guide holes 15 are symmetrically distributed on the end faces of the above-mentioned two end covers, and each guide hole 15 has one rod and three rods Parallel to each other, they are respectively rod I5, rod II9 and rod III13. The three rods between the two end covers are respectively equipped with connecting bu...

Abstract

The invention is an axial reciprocating parallel three-connecting rod converter, comprising frame mechanism and conversion mechanism, where bolts, spring washers and nuts connect end covers and supporting sleeve into fixed frame mechanism; the two end covers are made with three pilot holes, each of which is internally equipped with a rod, where the rod I is installed with connecting bump which isaxially located by locating bolt and washer on the rod and can only rotate on the rod, and the rods II and III are equipped with connecting concave blocks fixed on them by fixed bolt respectively andprovided with connecting grooves, the connecting bump on the rod I is inserted into the connecting grooves on the rods II and III, so as to form rod-to-rod connection; the connecting bump is equippedwith drive block having left, middle and right positions, and when moving the drive block between the three positions, the connecting bump on the rod I is alternatively or simultaneously inserted intothe connecting grooves, so as to implement three-rod connection conversion.

Description

technical field [0001] The invention relates to a parallel three-rod connection converter, in particular to a conversion mechanism for three rod-to-rod connections that are parallel to each other and perform axial reciprocating motion. Background technique [0002] In mechanical transmission, it is very common to transmit power and motion through the rod system. The conversion mode of the connection between the rods among the three rods known to be parallel to each other and reciprocating in the axial direction is realized by changing the number of teeth of the gear or sprocket. , This conversion has many defects, such as complex structure, high manufacturing cost, multiple transmission pairs and low efficiency, large volume and difficult layout, etc. Contents of the invention [0003] In order to overcome the shortcomings of the existing three parallel rods and rod-to-rod connection conversion methods, the invention provides a parallel three rod connection converter. The ...
