Description

An automatic positioning transmission device

technical field

The invention relates to the field of mechanical processing of industrial automatic production lines, in particular to an automatic positioning and conveying device for rod-shaped special-shaped structures.

Background technique

With the development of society, in the manufacturing industry, the role of machines is becoming more and more important. In the past, people used to produce parts, but now the cost of people is getting higher and higher. Many manufacturers gradually use machines to replace people. In some large companies, there is only the entire production line in a workshop, and only one or a few people are required to take care of it. The production of parts is completed by machines. Moreover, when people are working, it is difficult to maintain concentration for a long time, resulting in the loss of parts. It is difficult to guarantee the precision, there are differences between the parts produced by the same person, and there are also differences between the parts produced by different people, but there is almost no difference between the parts produced by the machine, and the machine can work for a long time and reliably. It is difficult to point people. What's more, some processing places have a harsh environment and even toxic substances. From the perspective of people's health, machines are more suitable for work than people.

When the machine produces parts, it is often necessary to locate the position of the parts. The positioning devices of different parts are also very different. For a production line, the quality of the positioning device directly affects the quality of subsequent processing. The reliability of the positioning device The performance also determines the processing efficiency of the production line. In the processing of complex parts, such as bar cutting, operations such as deflection and movement of the workpiece are often involved, so as to locate the position of the workpiece and ensure that the specified parts are processed. For precise positioning, manipulators are generally used to perform operations such as retrieving, moving, and deflecting. However, the structural design of the manipulator is complex and the reliability is not high during work. If the workpiece is to be positioned, other technologies must be used, and the cost is high. Maintenance more difficult. If the workpiece is positioned by humans, the manipulator will pick up the material at the location. After the processing is completed, the manipulator will place the workpiece at the designated position, and then the man will take the workpiece back for the next process. The process not only involves manual material picking and positioning The feeding process also involves the loading and unloading process of the manipulator, resulting in long processing time and low work efficiency. Moreover, human factors are involved in the process, which will have a certain impact on the quality of the workpiece and greatly increase the processing cost.

Contents of the invention

The invention provides an automatic positioning transmission device, which can be applied to the automatic industrial production line, and can also be applied to the positioning of parts of a single mechanical equipment. The structure, the transition between the special-shaped part and the rod-shaped part is a tapered surface. The device can automatically pick up the material from the workpiece storage place, then automatically and accurately position the workpiece, and finally transfer it to the next processing procedure. It is safe, reliable, high in efficiency and low in cost, and can be widely used in actual processing.

The guide mechanism includes: symmetrically arranged on the feeding bottom plate, guide columns located on both sides of the notch of the groove; blanking support pieces arranged on the groove walls on both sides of the groove, and the blanking support pieces are slidably installed in the groove through the reset member on the sidewall.

The guide columns are generally two groups, each group of guide columns is two, respectively arranged on both sides of the guide groove, the two groups of guide columns are far away from each other, close to the clamping device and the ejecting device respectively, and the two sides of the groove are close to the sides of the pushing device. A blanking support is installed on one side, and a blanking support sheet is installed in the above-mentioned blanking support. There are two blanking supports, which are symmetrically distributed on both sides of the groove, and the blanking supports are connected with the return spring. When working, the feeding bottom plate reaches the pick-up position under the action of the feeding drive device, and the workpiece falls on the feeding bottom plate. Due to the design of the groove, the workpiece just falls into the groove, and the workpiece is roughly positioned. However, due to the falling Due to factors such as speed and workpiece jump, the end of the workpiece may not be in the groove. Through the design of the guide columns symmetrically distributed on both sides of the groove, it is ensured that one end of the workpiece falls in the groove, and at the same time, the other end of the workpiece falls in the groove. Between the two blanking pallets, the initial distance between the two blanking pallets is smaller than the end face of the workpiece. When the workpiece falls between the two blanking pallets, the two blanking pallets are under the action of the workpiece Make the opposite movement away from the workpiece to achieve soft clamping of one end of the workpiece.
