Description

Technical Field

[0001] The present application relates to the technical field of mechanical processing, and in particular to a tool wear compensation mechanism of a boring device. Background Art

[0002] In the field of mechanical processing, boring is a common hole processing method, and its accuracy and efficiency have an important impact on product quality and production costs. In the boring process, tool wear is inevitable. As tool wear increases, processing accuracy and efficiency will be seriously affected. Therefore, how to achieve automatic compensation for tool wear and improve processing accuracy and efficiency has always been a research hotspot in the field of mechanical processing.

[0003] At present, the traditional tool wear compensation method mainly relies on manual adjustment or replacement of tools, which is not only inefficient but also easily affected by human factors, resulting in unstable machining accuracy. Although there are some automatic compensation mechanisms on the market, most of them are complex in structure, high in cost, and it is difficult to guarantee compensation accuracy and stability.

[0004] The above contents are only used to assist in understanding the technical solution of the present application, and do not constitute an admission that the above contents are the closest prior art to the present application. Summary of the invention

[0005] Based on this, the present application provides a tool wear compensation mechanism for a boring device to solve one of the above technical problems.

[0006] The technical solution adopted by the present application to solve its technical problems is: a tool wear compensation mechanism of a boring equipment, including: a hydraulic cylinder, as the main component of the compensation mechanism, including hydraulic oil, a first piston and a second piston; a hydraulic tool holder, installed at the front end of the hydraulic cylinder, using hydraulic pressure to fix or unlock the boring tool; a controller, installed at the outside of the first piston, for receiving and processing data from a pressure sensor installed on the inside of the first piston, and after comparing and processing with a set pressure value, regulating the operation of a motor located on the left side of the first piston, the motor drives the push rod to move, thereby regulating the movement of the first piston, so that the pressure in the hydraulic cylinder returns to the set value, thereby achieving tool wear compensation.

[0007] In some embodiments, the hydraulic cylinder has a cavity filled with hydraulic oil, the first piston is on one side of the hydraulic cylinder, and the second piston is on the other side of the hydraulic cylinder.

[0008] In some embodiments, the boring tool is located on the right side of the second piston and is fixedly connected thereto, and can move simultaneously with the second piston.

[0009] In some embodiments, the sensor is installed on the side of the first piston close to the hydraulic oil, which can monitor and transmit the liquid pressure in the cavity in real time and transmit it to the controller.

[0010] In some embodiments, the motor can rotate forward or reverse to push or pull the push rod to translate in the cavity of the hydraulic cylinder.

[0011] In some embodiments, the motor and the push rod are fixedly connected, and the push rod and the first piston are also fixedly connected.

[0012] In some embodiments, the inner side of the hydraulic tool handle close to the boring tool is made of a deformable material and fits the boring tool. The clamping force of the inner wall of the hydraulic tool handle on the boring tool can be increased (reduced) by adding hydraulic oil or extracting hydraulic oil, thereby achieving the fixing and unlocking of the boring tool.

[0013] In some embodiments, the hydraulic oil is filled and pumped out through an oil inlet and outlet hole on the hydraulic tool handle.

[0014] In some embodiments, the tightness of the hydraulic tool handle can be adjusted manually or automatically by a controller.

[0015] In some embodiments, the hydraulic cylinder and the hydraulic tool holder are detachable.

[0016] The beneficial effect of the present application is that the hydraulic pressure is detected by the sensor, and then the hydraulic pressure and the set value are adjusted in real time through the cooperation of the motor, the push rod and the controller, so as to maintain the specified operating accuracy compensation when the boring tool is working, and another set of hydraulic system can be used to clamp and loosen the boring tool at the same time. The tool wear compensation mechanism of the boring equipment described in the present application has the beneficial effects of high degree of automation, simple operation, strong adaptability, etc., which can effectively solve the problem of reduced processing accuracy and efficiency caused by tool wear, and improve the overall performance and processing quality of the boring equipment.
