Abstract
The invention discloses a positioning locking mechanism of a mandrel block, belonging to the field of seamless tube production equipment. The positioning locking mechanism is characterized in that the left end and the right end of the mandrel block are hinged with a left traction bracket and a right traction bracket of a triangle formed by three hinge points through a left first pin shaft and a right first pin shaft respectively, wherein the left traction bracket and the right traction bracket are hinged with two end points of a connecting rod through a left third pin shaft and a right third pin shaft respectively; the lower end point of a rocker is hinged with a locking block which can move in a vertical slide way; a left end point and a right end point of a transmission chain are hinged with the left traction bracket and the right traction bracket respectively; a stop block bracket is arranged on a part which is arranged in the front lower space of the mandrel block; the stop block is arranged on the stop block bracket through a pin shaft; the front end point of the stop block is connected with a spring which is fixedly arranged on the foundation; and a locking groove is formed in the rear end of the stop block. The positioning locking mechanism has the advantages of simple structure, convenience in manufacturing, less investment cost and suitability for small-scale production and laboratory use.
Description
Technical field
The invention belongs to seamless tubular goods production equipment field, be specifically related to a kind of ejector rob trolley provided positioning lock locking mechanism.
Technical background
At present, producing in the machine of seamless tubular goods, on push rod or mandrel trolley, all adopt pressure type hydraulic pressure positioning locking device both at home and abroad, its complex structure, volume is large, takes up room large, auxiliary device is many, and cost costliness is not suitable for small lot batch manufacture and scientific research laboratory and uses.
Summary of the invention
The object of the invention is to provide a kind of designs simplification, and occupation of land space is little, and equipment investment is few, is applicable to the ejector rob trolley provided positioning lock locking mechanism that small lot batch manufacture and laboratory are used.
The present invention realizes like this, as shown in Figure 1, ejector rob trolley provided 1 both ends, left and right are by left and right the first bearing pin 4, 4 ' respectively with have three the leg-of-mutton left and right of pin joint towing brackets 3, 3 ' is hinged, left and right towing bracket 3, between 3 ', pass through left and right the 3rd bearing pin 6, 6 ' is hinged with connecting rod 2 two-end-points respectively, the intermediate point of connecting rod 2 is hinged by middle bearing pin 8 and the upper extreme point of rocking bar 9, the lower extreme point of rocking bar 9 is hinged by rocking bar bearing pin 10 and the latch 11 that can move up and down, the two ends, left and right of driving-chain 17 respectively with left and right towing bracket 3, 3 ' by left and right the second bearing pin 5, 5 ' is hinged.The position of setting in ejector rob trolley provided front lower place is provided with block support 14, and block 13 is arranged on block support 14 by block bearing pin 16, and block 13 right-hand members offer lock groove 12, and its left end is connected with the spring 15 being fixed on ground.
Advantage of the present invention and good effect are designs simplifications, easily manufactured, and investment cost is few, are applicable to small lot batch manufacture and laboratory and use.
Brief description of the drawings
Fig. 1 is structural representation of the present invention
In figure: 1---ejector rob trolley provided, 2---connecting rod, 3,3 '---left and right towing bracket, 4,4 '---left and right the first bearing pin, 5,5 '---left and right the second bearing pin, 6,6 '---left and right the 3rd bearing pin, 7---guide rail, 8---middle bearing pin, 9---rocking bar, 10---rocking bar bearing pin, 11---latch, 12---lock groove, 13---block, 14---block support, 15---spring, 16---block bearing pin, 17---driving-chain
Detailed description of the invention
As shown in Figure 1, drive driving-chain 17 to drive ejector rob trolley provided 1 on guide rail 7, to be moved to the left, simultaneously drivening rod 2 moves together and drives latch 11 to depart from vertical slideway by rocking bar 9 and is moved to the left, stop when reaching latch 11 and falling into lock groove 12; When anti-car, driving-chain 17 is done motion in the other direction, drives ejector rob trolley provided 1 to move to right, and reaches latch 11 and falls into vertical channel stop motion.
