Description

A kind of numerical control equipment

technical field

The present invention relates to numerical control equipment, in particular to a main processing head numerical control machine tool, numerical control painting equipment, numerical control welding equipment, numerical control laser cutting equipment, numerical control laser welding equipment, numerical control plasma cutting equipment, numerical control screw mounting equipment, numerical control gas cutting equipment, numerical control Robot pick-up equipment, etc. the

Background technique

Existing numerical control equipment, one is workbench movement. For example, in the invention patent with the application number of 201010284237.9, a CNC gantry vertical compound machine tool is disclosed, including a base, a workbench, and a column. The column is movably connected by a column guide rail or fixedly connected with a composite beam through a fastener. The composite beam passes through the beam. There are more than 2 sliding saddles that are movably connected or fixedly connected by fasteners, and the sliding saddle is movably connected with the main shaft device through the ram guide rail; the base, column, composite beam, and main shaft device are equipped with screw drive devices, and the screw drive The devices are all connected to the electrical numerical control device. the

One is the gantry movement. For CNC equipment with this structure, one way is to drive the gantry to move back and forth. The driving mechanism needs to include two X-direction screw rods or X-direction synchronous belts, etc. and two power sources, and two synchronous motors are required to drive the gantry. Because it is difficult for two synchronous motors to achieve completely synchronous motion, or one of the motors slows down or speeds up, the movement of the X-direction slide is unbalanced and torque is generated, which makes the X-direction slide move in the X direction, resulting in X-direction The problem of poor stability, inaccurate positioning and poor movement of the sliding seat. One way is that the X-direction screw or the X-direction synchronous belt is located on one side of the gantry, and the driving force is completely biased to one side, causing the unbalanced movement of the gantry and generating torque to make the gantry shift in the Y direction and cause the Y-direction slide to move. The stability is not good, the positioning is not accurate, the movement is not smooth, the movement cannot be too fast, and it cannot adapt to the large machine tool with large spacing between X forward guide rails and X backward guide rails. the

The above-mentioned movement of the main shaft in the prior art requires the movement of the base or the movement of the gantry. The weight of the base of the clamped workpiece and the weight of the workpiece or the weight of the gantry that needs to move is much heavier than the weight of the main shaft device and its bearing device, so it is a great waste of processing. The energy of the workpiece increases the inertia of the moving parts of the equipment, reduces the feeding accuracy of the equipment and the machining accuracy of the workpiece, reduces the moving speed and processing efficiency in the Y direction, and increases the wear between the moving parts of the equipment and the guide rail. Since the base guide rail or the gantry guide rail is installed below the workpiece clamping device, the iron filings etc. processed from the workpiece are easy to enter into the guide rail. the

In the invention patent with the application number 201010155118.3, a CNC machining center is disclosed, which includes a workbench for clamping workpieces. The workbench is provided with a horizontal column, and a cross slide is installed on the horizontal column. The upper end of the cross slide is connected to There is a Y-axis screw, the lower end of the cross slide is connected with an X-axis screw, and the upper part of the Y-axis screw is provided with a vertical column that can extend the vertical ram to move up and down. The vertical column is connected with a Z-axis screw, and the vertical ram The lower end is connected to the spindle with the tool. In the moving column type CNC machining center of the invention, since the longitudinal column on which the main shaft is installed is only supported on one side, the main shaft has poor stability, inaccurate positioning, poor movement, and too fast movement during movement. the

It can also move along the three axes of X, Y, and Z. Angle-adjustable guide rail grinding machine for grinding horizontal planes or planes inclined to the horizontal plane. The fourth and fifth grinding wheels are mounted on two independently moving Z guide rods. Since the fourth grinding wheel and the fifth grinding wheel are installed on the same X-direction sliding seat and Y-direction sliding seat, and share the same workbench, the fourth grinding wheel is used to grind the horizontal plane and the fifth grinding wheel is used to grind the horizontal plane or the plane inclined to the horizontal plane. , the workpiece only needs to be clamped once to improve efficiency, and more importantly, the benchmark is consistent, which is easy to ensure the accuracy and parallelism of each surface. The outer cylindrical grinding wheel and the inner cylindrical grinding wheel are installed on the same Z guide rod. Since the outer cylindrical grinding wheel and the inner cylindrical grinding wheel are installed on the same X-direction sliding seat, Y-direction sliding seat, and Z guide rod, and share the same workbench, the sixth grinding wheel is used to grind the horizontal plane and the seventh grinding wheel is used to grind the horizontal surface. When the plane is horizontal or inclined to the horizontal plane, the workpiece only needs to be clamped once, which improves efficiency, and more importantly, the benchmarks are completely consistent and the accuracy is higher. the

The beneficial effects of the present invention are: the main support frame is a closed-loop structure, on the one hand, the supporting force supporting the X-direction sliding seat can be more evenly transmitted to the base, so it has a good bearing effect on the X-direction sliding seat, and the rigidity is good. It is very beneficial for the processing head to process the workpiece from the top down. On the other hand, it can realize that the X-direction screw or the X-direction timing belt is located between the X forward guide rail and the X rear guide rail, so that only one X direction can be realized. The screw rod or X-direction synchronous belt and a power source drive the X-direction slide to move, and the machining datum of the guide rail position is consistent, which ensures the shape and position accuracy of the guide rail. To drive the X-direction slide to move back and forth, only one X-direction screw or X-direction synchronous belt and one power source are needed, which can overcome the need to install two synchronously moving motors at the positions of the X front guide rail and the X rear guide rail to drive the X direction slide. Because it is difficult for two synchronous motors to achieve completely synchronous motion, or one of the motors slows down or speeds up, the movement of the X-direction slide is unbalanced and torque is generated, causing the X-direction slide to move in the X direction, resulting in The problem of poor stability, inaccurate positioning, and poor movement when the X-direction slide moves. The X-direction screw or the X-direction synchronous belt is located between the X-forward guide rail and the X-rearward guide rail. It can also overcome the problem of only installing a driving device at the position of the X-direction guide rail or the X-rearward guide rail to drive the X-direction slide seat. The force is completely biased to one side, resulting in unbalanced movement of the X-direction slide, resulting in torque that causes the X-direction slide to move in the X direction, resulting in poor stability, inaccurate positioning, poor movement, and too fast movement of the X-direction slide. It cannot adapt to large machine tools with large spacing between X forward guide rails and X backward guide rails. Since the main processing head can move in the X, Y, and Z directions, the workpiece clamping device such as the workbench for clamping the workpiece does not need to move in the X, Y, and Z directions. On the one hand, due to the main processing head and The weight of the X and Y sliding seats of the carrying device is much lighter than the total weight of the traditional workbench and the workpiece that need to be moved to clamp the workpiece, so it can greatly save energy when processing the workpiece and reduce the inertia of the moving parts of the equipment, thereby It can greatly improve the displacement sensitivity of the moving parts and the processing accuracy of the workpiece, increase the moving speed in the X direction and Y direction, improve the processing efficiency, and greatly reduce the wear between the moving parts of the equipment and the guide rail; on the other hand, it can realize multiple clamping workpieces. The reciprocating motion or rotary motion of the worktable realizes the transfer of workpieces between different positions and realizes the assembly line operation. Since the X forward guide rail, X backward guide rail, Y left guide rail, Y right guide rail, and Z guide rod are all installed above the workpiece clamping device, the iron chips processed from the workpiece basically do not need special protection. It will not enter the guide rail above the processing head. On the one hand, the structure of the guide rail is simplified, and on the other hand, the life of the guide rail is greatly improved. the
