Description
Technical Field
The invention relates to screw mounting equipment, in particular to a key mechanical structure in a screw driving machine in automatic production and assembly equipment of an electrical product, namely a parallel three-rail double-batch screw driving mechanism.
Background
The current trend of automation technology development is that machines replace former manual repetitive operation work, and in the processing process of electrician products, automatic screw machines are largely used for assembling the products by screwing. In the process of screwing, screws with the same height of a working plane and the like are often subjected to multi-position synchronous operation, meanwhile, the process flow of screwing can be generally divided into two steps of screw approaching and screw screwing, and the two steps are generally driven by independent power or adopt a spring rod type linkage structure. The spring rod type linkage is easy to generate vertical vibration in the advancing process, so that the screw in the screw clamp mouth is moved to influence the success rate of the subsequent screw screwing-in step; the screw clamping head of the traditional screw driving mechanism adopts a single or double-track structure in the movement direction, the positioning of screw holes can only ensure the precision in the point or line direction, and the screw processing quality of products is low easily caused particularly in the scene application with high requirement on the positioning precision of the screw holes.
Disclosure of Invention
The invention aims to provide a parallel three-rail double-batch screw driving mechanism of a single power source driven by a cylinder, which has the advantages of simple structure, high repeated positioning precision and obvious efficiency improvement.
In order to realize the purpose of the invention, the invention adopts the following technical scheme:
the screw driver comprises a mounting plate, and is characterized in that the top end and the bottom end of the mounting plate are respectively and fixedly connected with an upper limiting plate and a lower limiting plate, the top surface of the upper limiting plate is fixedly provided with an air cylinder, two parallel linear sliding rails are vertically arranged between the upper limiting plate and the lower limiting plate, the upper portion and the lower portion of each linear sliding rail are respectively provided with an upper sliding block and a lower sliding block which are matched with the upper portion and the lower portion, the upper sliding block and the lower sliding block are respectively and fixedly connected with an upper supporting plate and a lower supporting plate, the top of the upper supporting plate and the top of the lower supporting plate are respectively connected with a push rod of the air cylinder, the lower portions of the upper supporting plate and the lower supporting plate are respectively and horizontally and fixedly provided with an upper supporting plate mounting plate and a lower supporting plate mounting plate, two electric drivers are vertically arranged on the upper supporting plate mounting plate, a driver nozzle of each electric.
The top of the linear optical axis extending out of the upper support plate mounting plate is sleeved with a linear bearing, a cushion pad and an optical axis locking ring from bottom to top respectively, the linear bearing and the cushion pad are fixedly mounted on the upper support plate mounting plate, and the optical axis locking ring is sleeved at the top of the linear optical axis.
The straight line optical axis is positioned on the vertical middle line of the connecting line of the two linear slide rails.
The main structure of the screwing device is a three-rail parallel motion bearing platform consisting of an upper support plate and a lower support plate along two groups of linear slide rails, a group of linear optical axes and linear bearings, wherein in an initial static state, an optical axis locking ring on the linear optical axes of the lower support plate is fixed at a high position by the upper support plate through the linear bearings, so that the lower support plate is at the same high position; when the screwing action is executed, the upper support plate is driven by the cylinder to drive the electric screwdriver to move downwards, and meanwhile, the lower support plate automatically moves downwards under the action of gravity after the support force of the linear optical axis is removed, and moves to the end of the lower limit plate together with the screw clamping mouth with the screw; and after the lower stroke of the screw clamp mouth is limited, the upper supporting plate and the screwdriver continue to move downwards, and the screw is locked on the workpiece after the screw is propped against the screw, so that the locking of the screw is realized. At the moment, the upper support plate and the lower support plate are both in a low position, and the upper half part of the linear optical axis and the optical axis locking ring are exposed together and are higher than the upper support plate. Then, the cylinder pull rod pulls the upper support plate upwards, the linear bearing fixed on the upper support plate pulls the optical axis locking ring upwards so as to pull the linear optical axis fixed on the lower support plate, and then the lower support plate is restored to the initial high position along with the upper support plate. And repeating the steps in turn to finish the working process of screwing one screw after another.
The invention has the following structural characteristics:
1. the three-axis parallel structure is formed by two groups of linear slide rails, a group of linear optical axes and linear bearings, and the three axes realize the equidirectional and all-directional movement of the upper support plate and the lower support plate in the vertical direction.
2. The straight line optical axis is located the perpendicular midline of two linear slide rail line, and gliding triaxial parallel structure forms the triangulation location structure at the top view plane from top to bottom simultaneously, and this structure can be guaranteed: under the combined action of the linear slide block and the linear bearing, the offset of the upper support plate and the lower support plate in the direction of the planar XY axis is minimum in the motion process, and the effect of improving the precision is achieved.
3. The linear bearing fixed on the upper support plate, the cushion pad, the linear optical axis of the lower support plate and the optical axis lock ring sleeved on the top of the linear optical axis form a linkage mechanism in the vertical direction. The downward power of the lower support plate and the screw clamp mouth is natural gravity, after the lower support plate descends to the lower limit position, the linear bearing is fixed on the upper support plate, the vertical distance between the lower support plate and the upper support plate is changed to reach the minimum distance, and the screw of the screw clamp mouth on the lower support plate is pushed out by the upper support plate.
