On the one hand, because the positioning of the product placement fixture is very unstable, a lot of time and manpower are consumed in the clamping, and the operator is prone to unexpected mistakes during the operation. On the other hand, the processing The technological process is unstable and the defective rate is high. With the development of the company, it has gradually been unable to meet the production and quality requirements.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a self-centering device for a multi-station machine tool which is semi-automatic, one person can operate multiple machines, the product quality is good, the quality is stable, and the production efficiency is high.

In order to achieve the above object, the technical solution adopted in the utility model is:

A self-centering device for a multi-station machine tool, comprising a base, a rotating lifting cylinder is installed in the middle of the base, a pressure plate is installed on the movable end of the rotating lifting cylinder, and the base is symmetrical with the rotating lifting cylinder as the center There are multiple product supports, the top of the product support is a positioning platform, the positioning platform is provided with a product positioning device, and the pressing plate is provided with a plurality of pressure heads corresponding to the position and quantity of the positioning platform , the pressure head is an annular shape matching the size of the product, the middle part of the pressure head is a processing hole convenient for product processing, and the rotary lifting cylinder drives the movement of the pressure plate to set a working station and a non-working station In the working position, the rotary lifting cylinder drives the pressing plate down and rotates so that the pressing head of the pressing plate just presses down on the working platform to fix the product. In the non-working station, the rotating lifting cylinder drives the pressing plate of the pressing plate The head rises and rotates away from the work platform for easy access to parts.

The product positioning device includes a jacking cylinder arranged in the product support and a plurality of positioning pins installed on the movable end of the jacking cylinder, a groove is arranged in the middle of the positioning platform, and multiple pins are arranged in the groove. A positioning through hole, a positioning pin is movable in the positioning through hole, and the top of the positioning pin can extend out of the positioning through hole or shrink in the positioning through hole driven by the jacking cylinder.

A silicone pad is provided on the contact surface between the pressure head and the product.

Two product supports are symmetrically arranged on the base with the rotary lifting cylinder as the center.

Due to the adoption of the above scheme, the device uses a rotary lifting cylinder to drive the pressure plate, and a plurality of product supports are arranged around the rotary lifting cylinder, and through the rotary pressing of the pressure plate, multiple products to be processed can be fixed in one action, and product processing After finishing, the pressing plate is lifted by the rotary lifting cylinder, so that it is convenient to take out the product, which greatly improves the quality and speed of processing. This device is also equipped with a product positioning device, so as to facilitate the positioning of the product placed on the positioning platform. There is a silicone pad on the contact surface between the indenter and the product to prevent the indenter from wearing the product. In summary, this device can realize one person to operate multiple machines, making the product quality more stable and improving the product yield and production efficiency. .

Detailed ways

Below in conjunction with accompanying drawing, the specific implementation manner of this patent is described in further detail.

As shown in Figures 1 to 3, a self-centering device for a multi-station machine tool includes a base 3, a product support 2 and a rotary lifting cylinder 4, and the rotary lifting cylinder 4 and the product support 2 are all installed on the base 1. The rotary lift cylinder 4 is arranged in the middle of the base 3, and the product support 2 is arranged on both sides of the rotary lift cylinder 4 with the rotary lift cylinder 4 as a symmetrical axis. The product support 2 is provided with a jacking cylinder 21. The top of the product support 2 is a positioning platform 23, a groove is provided in the middle of the positioning platform 23, and a plurality of positioning through holes are arranged in the groove, and a plurality of positioning pins are installed on the movable end of the jacking cylinder. 22. A positioning pin 22 is movable in the positioning through hole, and the top of the positioning pin 22 can extend out of the positioning through hole or shrink in the positioning through hole driven by the jacking cylinder, and the rotating A pressing plate 1 is installed on the movable end of the lifting cylinder 4, and the pressing plate 1 is provided with a plurality of pressure heads 11 corresponding to the position and quantity of the positioning platform. The middle part of the pressure head 11 is a processing hole for convenient product processing. The rotary lifting cylinder 4 drives the pressure plate 1 to move and is provided with a working station and a non-working station. The pressure plate 1 descends and rotates so that the pressure head 11 of the pressure plate 1 just presses down on the working platform 23 to fix the product. At the non-working station, the rotary lifting cylinder 4 drives the pressure head of the pressure plate to rise and rotate away. Work platform for easy pick-up.

When working: Fix the device on the CNC machine, then start the jacking cylinder to drive the positioning pins up, place the product to be processed on the positioning platform, and position the product through the positioning pins. Start the rotary lifting cylinder to drive the pressure plate to rotate downward, so that the pressure head can fasten the product to be processed on the positioning platform, and then start the jacking cylinder to drive the positioning pin back to the position, so as to facilitate product processing. After processing, start the rotary lifting cylinder , to drive the pressure plate to rotate and rise, so that it is convenient to take the product.
