DETAILED DESCRIPTION

[0017] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0019] like Figure 1 As shown, the present application provides a power tool turret capable of automatically replacing tools, including a tool disc 1, the tool disc 1 being provided with twelve groups of stations for installing and fixing a tool seat, a power seat 11 being provided on one side of the tool disc 1, a driving member 12 being provided on one side of the power seat 11, and the driving member 12 being used to drive the tool disc 1 to rotate; In the present application, the method in which the driving member 12 drives the cutter disc 1 is the prior art. The driving member 12 can be set as a driving motor, and a power module is provided in the cutter disc 1, and a helical gear is provided in the power seat 11. Therefore, the driving motor is used to drive the helical gear for transmission, and drives the power module to rotate the cutter disc 1.

[0020] At the same time, a tool changing seat 2 is fixedly installed on one group of tool seats of the tool disc 1. The tool changing seat 2 has a tool interface 21 for clamping a milling cutter or a turning tool, etc., and a tool magazine (not shown in the figure) is also arranged on one side of the tool changing seat 2. In the present application, sixty tools are arranged in the tool magazine, and a clamping robot (not shown in the figure) is also arranged on one side of the tool magazine. Therefore, the tool in the tool magazine can be transferred to the tool interface 21 by the clamping robot, and then it can be fixed by the tool changing seat 2.

[0021] like Figure 4 As shown, the pipe on one side of the cutter disc 1 away from the driving member 12 is connected to a rotary joint 3, and the pipe inside the rotary joint 3 is connected to multiple groups of oil distribution shafts 31, and the multiple groups of oil distribution shafts 31 are fixedly installed on the power seat 11, so that the oil in the power seat 11 can be drawn out through the oil distribution shaft 31 and transferred to the cutter disc 1 through the rotary joint 3; In order to make the tool changer 2 automatically clamp the tool, Figure 3 As shown, a tool locking oil chamber 22 is provided in the tool changing seat 2, and the tool locking oil chamber 22 is located between the tool interface 21 and the tool changing seat 2, and tool releasing oil chambers 23 are provided on both sides of the tool locking oil chamber 22; At the same time, a locking detection valve 24 is provided on one side of the tool locking oil chamber 22, and the locking detection valve 24 is connected to the tool locking oil chamber 22 by a pipeline. The locking detection valve 24 is used to perform oil pressure detection on the tool locking oil chamber 22, and a release detection valve 25 is provided on one side of the tool release oil chamber 23, and the release detection valve 25 is connected to the tool release oil chamber 23 by a pipeline. The release detection valve 25 is used to perform oil pressure detection on the tool release oil chamber 23. In the present application, the locking detection valve 24 and the release detection valve 25 are pressure valves, and detection systems are provided on the outside for detecting pressure changes in the valve body.

[0022] like Figure 2 and Figure 4 As shown, a pipeline on one side of the rotary joint 3 is connected to a locking oil circuit inlet pipe 32, and the other end of the locking oil circuit inlet pipe 32 is connected to the tool locking oil chamber 22. At the same time, a pipeline on one side of the rotary joint 3 is also connected to a loosening oil circuit outlet pipe 33, and the other end of the loosening oil circuit outlet pipe 33 is connected to the tool loosening oil chamber 23. In addition, a loosening oil circuit inlet pipe 34 and a locking oil circuit outlet pipe 35 are connected to the rotary joint 3 by pipes. The loosening oil circuit inlet pipe 34 is connected to the loosening detection valve 25, while the locking oil circuit outlet pipe 35 is connected to the locking detection valve 24. Therefore, the oil entering from the locking oil circuit inlet pipe 32 will reach the tool locking oil chamber 22. At this time, the oil pressure will squeeze and discharge the oil in the tool locking oil chamber 22 toward the locking detection valve 24 and the locking oil circuit outlet pipe 35, while the oil entering from the loosening oil circuit inlet pipe 34 will reach the tool loosening oil chamber 23. At this time, the oil pressure will squeeze and discharge the oil in the tool loosening oil chamber 23 toward the loosening detection valve 25 and the loosening oil circuit inlet pipe 34.

[0023] In the present application, the tool changer seat 2 and the rotary joint 3 are controlled by a control system.

[0024] In summary: when the tool interface 21 needs to replace the tool, the control system supplies oil to the tool release oil chamber 23 through the release oil outlet pipe 33. At this time, the release detection valve 25 detects that there is an oil pressure change in the tool release oil chamber 23, and then transmits a signal to the control system to make the tool changer 2 release the tool position; Then, the tool that is loosened in the tool interface 21 is taken out by the clamping manipulator, and the tool to be replaced is taken out from the tool magazine by the clamping manipulator and installed at the tool interface 21. After the tool is changed, the locking oil inlet pipe 32 is supplied with oil. At this time, the locking detection valve 24 detects the oil pressure change in the tool locking oil chamber 22, and then transmits a signal to the control system to make the tool changer 2 lock and fix the tool, so the tool change is completed; Therefore, the tool at the tool interface 21 can be replaced through the rotary joint 3 and the tool changer 2, so that the number of tools for tool change is not limited, preventing the processing of complex parts due to insufficient number of tools, and the hydraulic detection system is used to detect the tool release and locking action, which is safe and reliable.
