Description

Technical Field

[0001] The invention relates to the technical field of machine tool engineering, in particular to a central support for a processing machine tool which can move with a tool and can also be controlled by a program to move independently. Background Art

[0002] Currently, when lathes process long workpieces, there are only two fulcrums: the chuck and the tailstock top, or there is a fixed center bracket in the middle as the third fulcrum. This is still not enough when it comes to very long workpieces, unless multiple center brackets are installed in the middle, which greatly increases the cost.

[0003] Especially when processing screw rods and very long workpieces, a chuck is used to clamp one end of the workpiece and a tailstock is used to assist in tightening the other end of the workpiece. This will easily cause the workpiece to vibrate and the tool to deflect during turning, and the workpiece will vibrate greatly, making it easy for the processed product to be defective. Summary of the invention

[0004] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a movable center support for a processing machine tool to solve the problem that it is difficult to process long workpieces on existing lathes.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a movable center support for a processing machine tool, comprising a center support body, on which a moving structure, a clamping structure and a control panel are arranged, and the control panel controls the forward and backward movement of the moving structure and the clamping and releasing of the clamping structure.

[0006] Preferably, the central support body further includes an upper seat and a lower seat, and the upper seat is fixedly disposed on the lower seat.

[0007] Preferably, the clamping structure is a clamping claw connecting two high-pressure oil pipes, and also includes a hydraulic station and a solenoid valve, and the solenoid valve signal is connected to a control panel.

[0008] Preferably, the movable structure is a lower seat arranged at the bottom end of the center bracket, a screw is arranged on one side of the lathe, the lower seat is threadedly connected to the screw, the screw is driven by a motor, the motor signal is connected to the control board, limit slots are opened on both sides of the lower seat, two guide rails are arranged on the lathe, and the limit slots are clamped on the guide rails.

[0009] Preferably, an oil drain is provided on the lower workpiece.

[0010] Preferably, an oil circuit block and an oil circuit bracket are provided on the upper seat for guiding the oil pipe.

[0011] Preferably, the lead screw is mounted on the inner bottom of the lathe via a bearing.

[0012] The beneficial effects of the present invention are as follows: the central bracket in the present invention has a simple structure, is easy to use, can move with the tool, and the fulcrum during processing is close to the processing point, which effectively prevents tool vibration and tool deflection, ensures the stability of the processing size, and thus meets more usage requirements.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Embodiment 1, as Figure 1 As shown, a movable center support for a processing machine tool includes a center support body 10, on which a moving structure, a clamping structure and a control panel are arranged, and the control panel controls the forward and backward movement of the moving structure and the clamping and releasing of the clamping structure.

[0018] Furthermore, the central support body 10 further includes an upper seat 9 and a lower seat 4 , and the upper seat 9 is fixedly disposed on the lower seat 4 .

[0019] Furthermore, the clamping structure is a clamping jaw 11 connecting two high-pressure oil pipes, and also includes a hydraulic station and a solenoid valve. The solenoid valve signal is connected to the control panel. The clamping and loosening of the program-controlled center frame is controlled by the hydraulic station and the solenoid valve driving two high-pressure oil pipes, one for oil inlet and the other for oil outlet.

[0020] Furthermore, the movable structure is a lower seat 4 arranged at the bottom end of the central bracket, a screw is arranged on one side of the lathe, the lower seat 4 is threadedly connected to the screw, the screw is driven by a motor, the motor signal is connected to the control board, limit grooves are opened on both sides of the lower seat 4, two guide rails are arranged on the lathe, and the limit grooves are clamped on the guide rails.

[0021] Furthermore, an oil drain 8 is provided on the lower workpiece.

[0022] Furthermore, an oil circuit block 1 and an oil circuit bracket 2 are provided on the upper seat 9 for guiding the oil pipe.

[0024] When in use, the central bracket is installed in the existing machine tool, and the control board is connected to the existing numerical control board; The present invention is controlled by a numerical control system during processing. When the start button on the machine tool is pressed, the machine tool will control the lathe turret to move with the tool to process the workpiece according to the program instructions written in the numerical control system. At the same time, program instructions are written to control the clamping and movement of the center frame to follow the tool. After the processing is completed, the program instructions are used to control the release and removal of the center frame. These cyclic processing actions are pre-written in the numerical control system and can be cyclically run. The center frame can also be manually input with program instructions to control the clamping, release and movement of the center frame.
