Double-stroke achieved jacking mechanism provided with connecting rod jacking device and pushing devices

Abstract

The invention relates to a double-stroke achieved jacking mechanism provided with a connecting rod jacking device and pushing devices. The connecting rod jacking device drives a left buoyancy needle installation base and a right buoyancy needle installation base to move upwards and is limited through limiting buffering screws, after limiting is carried out, the two sets of pushing devices synchronously drive corresponding pushing blocks to move along corresponding longitudinal sliding grooves, the oblique angle a on the rear side of the upper portion of each pushing block is in contact transition with the oblique angle b of the front side of the upper portion of the left buoyancy needle installation base and the right buoyancy needle installation base, as gaps exist between clamping blocks and groove holes of the clamping blocks, the left buoyancy needle installation base and the right buoyancy needle installation base continue to be pushed to ascend, the upper plane of each pushing block makes full contact with the lower plane of the left buoyancy needle installation base and the lower plane of the right buoyancy needle installation base, and then the riveting working procedure is carried out. The double-stroke achieved jacking mechanism solves the problems that under the situation that the space is limited, a conventional air cylinder mechanism cannot meet a gasket feeding height requirement and a jacking height requirement of a riveted 67 mm rivet at the same time, and space saving and efficient coherent actions are achieved by arranging the synchronous pushing devices.

Description

Technical field: [0001] The invention relates to the field of jacking mechanisms, and more specifically relates to a jacking mechanism with a connecting rod jacking device and a jacking device that realizes double strokes. Background technique: [0002] On the automatic assembly line of children's chairs, a floating center needle is installed on the floating center needle mounting seat, and there are gaskets fed into the floating center needle. The gasket needs to be delivered to a certain height and the lifting height requirement of the long rivet needs to be completed. The conventional cylinder In the case of limited space, the mechanism cannot meet the requirements of the gasket delivery height and the lifting height of the 67mm rivet riveting at the same time. In the prior art, for example, the patent with the application number 2011101404174, the patent name is a jacking device for a fastening mold transmission mechanism, the application date is 2011.05.27, and the appl...

Problems solved by technology

[0002] On the automatic assembly line of children's chairs, a floating center needle is installed on the floating center needle mounting seat, and there are gaskets fed into the floating center needle. The gasket needs to be delivered to a certain height and the lifting height requirement of the long rivet needs to be completed. The conventional cylinder In the case of limited space, the mechanism cannot meet the requirements for the delivery height of gaskets and the lifting height of 67mm riveting rivets at the same time

In the prior art, for example, the patent with the application number 2011101404174, the patent name is a jacking device for a fastening mold transmission mechanism, the application date is 2011.05.27, and the application publication number is CN 102285608 A, which discloses the following technical scheme: When the finished parts are placed on the lifting plate, the driving cylinder drives the driving hinge, the driving hinge drives the active connecting rod, and at the same time the active connecting rod drives the driven connecting rod, and the driving connecting rod and the driven connecting rod simultaneously drive the lifting plate to lift up , which discloses a device that utilizes a cylinder and a connecting rod mechanism to achieve a jacking effect, but the jacking device of the above-mentioned patent has a complex structure and the jacking height is limited; in the prior art, such as a patent with application number 201320742463.6, the patent name is vertical Arrangement bolt machine, application date 2013.11.22, authorized announcement number CN203649803 U, its disclosed technical scheme is: a cylinder is installed in the center of the bottom plate, the piston rod end of the cylinder is fixed with a push-up top plate with an inclined surface on the top, and the push-up top plate There is a delivery box on it, the bottom of the delivery box is an inclined plane, and the inclination angle between the inclined surface at the bottom of the delivery box and the inclined surface on the push-up top plate and the horizontal plane is α, that is to say, the process of pushing is realized through the cylinder. The bottom of the box is in contact with the transition at an oblique angle, and the action of pushing the delivery box to a certain height
