Description

Technical Field

[0001] This utility model relates to the field of clamping cylinder technology, specifically a clamping cylinder control circuit. Background Technology

[0002] The crossbeam of the moving beam gantry machining center can move up and down. During machining, the braking and rotation during the height adjustment process of the crossbeam ensures that the slide block remains in the high-rigidity part of the slide block. The high rigidity and high positioning accuracy of the machining advantages ensure the reliable quality of the machine tool. During the up and down movement of the crossbeam of the moving beam gantry, when the crossbeam moves to the designated position, the W-axis servo motor activates the "brake" device to prevent the crossbeam from falling due to vertical gravity. However, due to the excessive weight of the crossbeam assembly, the clamping force required by the single motor brake can easily cause excessive motor load. If the clamping force is insufficient, the crossbeam will fall, posing a certain safety hazard. To ensure the safety of use, a clamping cylinder control circuit is proposed. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows:

[0005] A clamping cylinder control circuit includes a hydraulic station. The inlet and outlet ends of the hydraulic station are connected to a return oil line and an outlet oil line. The other ends of the outlet oil line and the return oil line are connected to a hydraulic directional valve. The other side of the hydraulic directional valve is connected to a transfer line. The other end of the transfer line is fixedly connected to an oil distributor block. A connecting line is connected to the oil distributor block. The end of the connecting line is fixedly connected to a cylinder body assembly.

[0006] Preferably, the oil outlet pipeline and the oil return pipeline are designed in parallel and are interconnected.

[0007] Preferably, there are two connecting pipes, each connecting to one of the two cylinder body assemblies. The cylinder body assemblies and the connecting pipes correspond to each other, and the connecting pipes are Z-shaped.

[0008] Preferably, the connecting pipe, the transfer pipe, the oil outlet pipe, and the oil return pipe are made of the same material, and the diameter of the connecting pipe, the transfer pipe, the oil outlet pipe, and the oil return pipe is 16mm.

[0009] Preferably, the connecting pipeline, transfer pipeline, oil outlet pipeline and oil return pipeline all adopt the corresponding threaded connection structure.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0011] In this invention, two hydraulic cylinder assemblies are connected to the oil distribution block for oil supply, avoiding motor damage caused by insufficient oil supply. Furthermore, the hydraulic directional valve and hydraulic station are connected via oil outlet and return lines, allowing hydraulic oil to circulate between them. The hydraulic directional valve and hydraulic station can operate as dual pipelines simultaneously for emergency use. Therefore, when the system stops suddenly due to an unexpected power outage, the motor braking and hydraulic clamping system can quickly provide sufficient braking torque to ensure the crossbeam does not fall and endanger the workpiece and operator safety.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0016] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a clamping cylinder control circuit. Example

[0017] Combination Figure 1 As shown, the present invention provides a clamping cylinder control circuit, including a hydraulic station 8. The inlet and outlet ends of the hydraulic station 8 are connected to a return oil line 7 and an outlet oil line 6. The outlet oil line 6 and the return oil line 7 are designed in parallel and interconnected. The other ends of the outlet oil line 6 and the return oil line 7 are connected to a hydraulic directional valve 5. The other side of the hydraulic directional valve 5 is connected to a transfer line 4. The other end of the transfer line 4 is fixedly connected to an oil distributor 3. A connecting line 2 is connected to the oil distributor 3, and the end of the connecting line 2 is fixed... The cylinder body assembly 1 is connected to the cylinder body assembly 1. There are two connecting pipes 2, which are connected to the two cylinder body assemblies 1 respectively. The cylinder body assembly 1 and the connecting pipes 2 correspond to each other. The connecting pipes 2 are Z-shaped. The connecting pipes 2, the transfer pipes 4, the oil outlet pipes 6, and the oil return pipes 7 are all made of the same material. The diameter of the connecting pipes 2, the transfer pipes 4, the oil outlet pipes 6, and the oil return pipes 7 is 16mm. The connecting pipes 2, the transfer pipes 4, the oil outlet pipes 6, and the oil return pipes 7 are all connected by threaded connections.

[0018] Specifically, by using two hydraulic cylinder assemblies 1 in conjunction with connecting pipes 2 for oil return and supply, the fault tolerance of the device can be effectively increased, preventing the device from losing control instantly and causing harm to the staff if one of them fails. This improves the safety of the device. Furthermore, the cooperation of the two hydraulic cylinder assemblies 1 can enhance the responsiveness of the device, significantly improving the operating accuracy and practicality of the device.

[0019] The working principle and usage process of this utility model are as follows: First, anti-wear hydraulic oil is injected into the hydraulic station 8. The hydraulic directional valve 5 is opened by the CNC system. The anti-wear hydraulic oil in the hydraulic station 8 enters the cylinder body assembly 1 cavity through the 16mm oil outlet pipe 6, the hydraulic directional valve 5, the 16mm transfer pipe 4, the oil distribution block 3, and the 16mm Z-shaped pipe 2. The clamping cylinder is in the released state, and the crossbeam can move up and down. When the crossbeam moves to the designated position, the hydraulic directional valve 6 is closed by the CNC system, the clamping cylinder is depressurized and returns oil through the 16mm return oil pipe 7, and the crossbeam is in a stationary state.

[0020] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
