Background technique

In the prior art, the turntable of the machine tool is connected to the pallet through four conical positioning structures. The cone blower is the mechanism used to maintain the repeatable positional accuracy of the pallet. In order to prevent the phenomenon that the workpiece cannot be placed in the correct position due to the accumulation of debris on the table positioning pins connecting the table and the pallet, the chips are cleaned by blowing high-pressure air into the table positioning pins, but due to the The existence of cutting fluid causes some iron filings to adhere to the conical contact surface, which will cause wear to the conical surface during long-term pallet exchange. Customers often only find out when they process poor-quality products and have problems with machine tool precision.

Disadvantages/deficiencies of existing technologies:

The processing of the workpiece under the condition of poor cooperation between the turntable and the pallet of the machine tool seriously affects the accuracy and life of the machine tool, the accuracy of the product and the stability of the product quality.

Preferably, the blowing system includes an air compressor and an air pump.

Preferably, the controller is electrically connected to a prompt unit, and the prompt unit includes a buzzer and a display light.

A machine tool, comprising any one of the machine tool turntables and a pallet airtightness detection system described above.

The machine tool of the machine tool turntable and pallet airtightness detection system proposed by the utility model has the following beneficial effects: prevent impurities attached to the cone surface in advance, avoid the processing of the workpiece under the condition of poor cooperation between the turntable and the pallet, and improve the processing quality of the workpiece and the machine tool. Accuracy and life are greatly improved.

Description of drawings

In order to illustrate the technical solutions in the embodiments of the present utility model more clearly, the following will briefly introduce the drawings required for the description of the embodiments.

Fig. 1 is the structural representation of the utility model;

Among them, 1. Pallet; 2. Machine tool turntable; 3. Tapered surface; 4. Ventilation hole; 5. Blowing pipe; 6. Air-tight detection valve; 7. Blowing system; 8. Controller.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

As shown in Figure 1, the utility model proposes a machine tool turntable and pallet airtight detection system, including a machine tool turntable 2, a tray 1, a tapered surface 3 is provided on the machine tool turntable 2, and the tray 1 is set on the On the tapered surface 3, an air outlet is provided on the tapered surface 3; an air vent 4 is provided at the lower part of the turntable of the machine tool, and a detection device is communicated with the air hole 4; the detection device includes a The air blowing pipe 5 communicated with the air holes 4, the air blowing pipe 5 is connected with an airtight detection valve 6; Connect; the airtight detection valve 6 is electrically communicated with the controller 8 of the machine tool, and the airtight detection valve 6 passes the detected air pressure signal of the gas through itself to the controller 8. When the air pressure signal exceeds the set range, the controller 8 Send a stop signal to the actuator of the machine tool.

This system utilizes the air blowing system 7 of the machine tool, including an air compressor and an air pump, to continuously blow air to the contact surface where the conical surface of the turntable 3 and the pallet 1 are in contact. in the gas path. The air-tight detection valve 6 determines whether there is any impurity on the contact surface by comparing the actual passing air pressure with the set air pressure. If the air pressure becomes smaller, it indicates that there is impurity. The controller 8 will control the machine tool to stop to confirm the contact surface condition and correct The contact surface is cleaned to avoid the influence on the processing accuracy of the product

The controller 8 is connected to a prompt unit when it is powered on. The prompt unit includes a buzzer and a display lamp. When an abnormality occurs, the operator is reminded to check whether there are impurities on the conical surface of the turntable and the conical surface of the tray 1 .

Furthermore, if the system is applied to the exchange of double worktables or even multiple worktables, it can detect the cooperation of the contact surfaces after the exchange of worktables, avoid processing under poor cooperation, and have a great impact on the quality of the processed workpiece and the life of the machine tool. Big improvement.

The utility model also provides a kind of machine tool, comprises the leak detection system of machine tool turntable 2 and pallet 1 as described in any one above.

A machine tool, comprising the above-mentioned turntable of the machine tool and a system for detecting airtightness of the tray.

Various modifications to the embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
