Description

High-efficiency interchangeable clamping device for CNC machining center

technical field

The utility model relates to a fixture of a precision numerical control machining center, more specifically, relates to a high-efficiency interchangeable clamping device for a numerical control machining center capable of fast interchangeable positioning during production.

Background technique

In the processing and production process of the existing CNC machining center, the product to be processed is generally processed in a single manner. After the previous product is processed, it is necessary to take out the products one by one and put them into the fixture one by one before starting the machine processing, or the product is in the When replacing and installing interchangeable plates, it is necessary to position and fasten them one by one, which takes a long time for clamping and low efficiency; while the operating cost of the machine tool is basically fixed, but the processing process is divided into processing time and clamping time, only the processing time is in the actual processing of the product , and the intermittent clamping time itself does not create value, which wastes the processing time of the machine tool and reduces the production efficiency of the machine tool. Therefore, how to reduce the clamping time is one of the key factors to improve production efficiency.

Contents of the invention

The technical purpose of this utility model is to overcome the technical problems of the existing technology that the CNC machining center takes time to clamp products during the production process and thus affects the production efficiency, and provides a method that reduces the waiting time for clamping and can simultaneously improve the stability of processing and interchangeability. The efficient interchangeable clamping device of the unique CNC machining center.

The high-efficiency interchangeable clamping device of the CNC machining center includes a bottom plate, a fixed plate is arranged in the middle of the bottom plate, a positioning pin is arranged on the fixed plate, and an assembly clamp structure is arranged on one side of the fixed plate, and the clamping The structure includes a cylinder with a bottom plate, the cylinder is connected with a connecting rod, an exchange plate is arranged above the connecting rod, and a material positioning pin and a positioning hole are arranged on the exchange plate, between the fixed plate and the quick pressing plate The rotating shaft is connected with a pressing arm.

Further, the interchangeable board is provided with product card slots.

The utility model manufactures two interchangeable plates with the same precise size, and processes the holes matched with the fixed plate. In order to achieve the purpose of stable, fast and efficient clamping, the fixture is made into a horizontal base, and a fixed plate with positioning pins is installed on the fixed base. Independent, non-interfering cylinders and interlocking quick clamps are added on both sides of the base. To ensure smooth loading and unloading of materials. While the machine is processing the products on the first interchangeable board, put the products on another interchangeable board. It is enough to put the interchangeable plate of the product on it, and there is no need to take out and clamp the products one by one.

The beneficial technical effect of the utility model is that the clamping is realized at the same time of processing, the downtime clamping time is reduced, and the production efficiency is improved.

Detailed ways

1, in the structure of the high-efficiency interchangeable clamping device of the CNC machining center of the present invention, a bottom plate 108 is included, a fixed plate 106 is arranged in the middle of the bottom plate 108, and an assembly clip is arranged on one side of the fixed plate 106 structure, the clamping structure includes a cylinder 107 on the bottom plate 108, the cylinder 107 is connected with a connecting rod 103, and an exchange plate 101 is arranged above the connecting rod 103, and a material positioning device is arranged on the exchange plate 101. Pin 104 and positioning hole 109. On the other side of the fixed plate 106, the same cylinder 107 and connecting rod 103 structure, the quick pressing plate 102 that is located on the connecting rod 103 is used for fast pressing interchangeable plate 101, and described fixing plate is provided with positioning pin 105, A pressing arm is connected to the rotating shaft between the fixed plate 106 and the quick pressing plate 102 . In practice, the interchangeable board 101 is provided with product card slots.

In implementation, at first two interchangeable plates 101 are processed; the first interchangeable plate 101 is placed on the workbench according to the processing direction, and the product 100 is correspondingly put into the positioning pin 104 of the interchangeable plate 101 for positioning, and then Align the positioning hole 109 on the interchangeable plate 101 with the positioning pin 105 in the fixed plate 106 and insert it; start the air valve, press down the fast pressing plate 102 to compress the product 100 and the interchangeable plate 101; start the machining center button to align the product 100 for processing. While the product is being processed, the product 100 is loaded into the second interchangeable plate 101. After the product on the first interchangeable plate has been processed, the air valve is started, the cylinder and the fast pressing plate 102 are released, and the first interchangeable plate is removed. Change the plate, install the second interchangeable plate with the product installed, and cycle like this; comparison of the clamping time during intermittent processing: a set of fixtures with the product model J42 is calculated as 4 out of one, and the existing clamping and removal and The loading time is about 25 seconds, while the clamping time is about 12 seconds when the utility model technology is adopted, and the clamping efficiency is greatly improved.
