Rotating positioning device

Abstract

The invention discloses a rotating positioning device. The rotating positioning device comprises a main shaft, a gear and a sprocket. The lower end of the main shaft is arranged in a mounting slot. The gear is fixed on the upper part of the main shaft through the main shaft and the sprocket is fixed on the lower part of the main shaft through the main shaft. A positioning mechanism is fixed on theside of the sprocket. The positioning mechanism is fixed in the mounting slot. The positioning mechanism comprises a base plate, a spring and a positioning round pin. One end of the spring is fixed to the left end of the base plate through a Jimmy screw, and the other end is connected with the positioning round pin. The device is a mechanical device with accurate positioning, convenient disassembly and installation, convenient replacement of broken parts and low maintenance cost. Ordinary motors can replace servo motors, the parts are basically standard parts, easy to buy, at a favorable price, and can be timely replaced when broken, and the material cost is reduced. The device is installed inside a mold, small in size, does not occupy the design space of the mold, and does not conflict with a manipulator. The production efficiency and product qualification rate are improved. The device is also suitable for devices which require positioning with other mechanical rotations and has broad application prospects.

Description

technical field [0001] The invention relates to the field of mold processing, in particular to a rotary positioning device suitable for use in molds. Background technique [0002] With the continuous improvement of living standards, the types of daily necessities and cosmetics have become more diverse. What follows is that the competition among the major manufacturers is becoming more and more fierce. In order to make the products more beautiful and consumers to use the products more conveniently, our products need to have better ideas. One of them is that when the tooth cap is screwed on the bottle, the two have a positioning relationship, so as to facilitate the subsequent surface printing, and consumers can use the product more conveniently. In order to realize this function, the teeth of the tooth bars in the mold parts need to be in the same position, and the positional relationship does not change during the production process, so we add an oil cylinder or servo moto...

Problems solved by technology

In order to realize this function, the teeth of the tooth bars in the mold parts need to be in the same position, and the positional relationship does not change during the production process, so we add an oil cylinder or servo motor to the mold, but in the process of using the oil cylinder or servo motor, There are the following disadvantages: the cost of the servo motor is too high, when the servo motor is damaged, we often need to buy a new servo motor for replacement, and the maintenance cost is high; most of the servo motors on the market have positioning errors and instability. It does not meet the production needs of precision molds; if the mold uses an oil cylinder, the mold will become larger and the installation is cumbersome. The mold and the oil cylinder need a larger installation space. For large factories, the space utilization rate becomes low. For small As far as the factory building is concerned, it is not conducive to the future development; the use of oil cylinders will hinder the manipulator installed above the injection molding machine, resulting in the manipulator being unable to take out the produced injection products, which requires people to take them out, wasting manpower, and the production efficiency is low. There is a chance that the hair will stick to the product, and the product will sometimes fall on the ground, and the pass rate of the product will become lower
