technical field

The utility model relates to a machining equipment, in particular to a CD grain processing equipment.

Background technique

The CD pattern processing mainly uses the CD pattern processing equipment to suck the workpiece through the vacuum fixture, process the tool feed stroke and the cutting process stroke after the power is turned on. After the product is sucked tightly by the vacuum fixture, the processing button is started, and the feed cylinder drives the machining tool to feed the product to the processing surface. After the feed cuts into the surface of the workpiece, the horizontal feed cylinder pushes the processing tool for horizontal chip processing, so that the surface of the workpiece can obtain the CD pattern effect of gradually expanding radius.

In the current CD pattern processing equipment, when the feed cylinder drives the processing tool to the workpiece processing surface, the feed speed is relatively fast. When the processing tool quickly cuts into the high-speed rotating workpiece processing surface, on the one hand, the processing tool will be damaged. Excessive force is easy to damage. On the other hand, the center point of the cutting point on the surface of the workpiece is prone to poor chip removal, white dots, and too large center point will affect the appearance of the product.

As shown in Figure 3, more specifically:

As shown in FIGS. 1-3 , the positioning plate 200 is disposed on one side of the vacuum fixture 700 . Wherein, the output end of the feeding cylinder 100 is fixedly connected to the positioning plate 200 , and the processing tool 300 is also fixedly connected to one side of the positioning plate 200 . It should be understood that the cylinder body of the feed cylinder 100 is fixedly connected to other components, which are not shown in the figure. The feed cylinder 100 drives the positioning plate 200 to move, so that the processing tool 300 moves with the positioning plate 200 relative to the workpiece (not shown in the figure) clamped by the vacuum fixture 700 , and the processing tool 300 is fed.

Specifically, as shown in Figure 3, one end of the buffer 400 is fixedly connected to the positioning plate 200, and the other end of the buffer 400 is suspended; the outside of the suspended end of the buffer 400 is provided with a limiting plate 500, and the limiting plate 500 faces the buffer. One side of the device 400 constitutes a limit reference plane 500a. It should be understood that the limit datum surface 500a is located on one side of the buffer 400 along the feeding direction of the feed cylinder 100, so that when the feed cylinder 100 drives the machining tool 300 to feed, the casting of the buffer 400 is close to the limit datum surface 500a. When the feed cylinder 100 drives the processing tool 300 to move toward the workpiece, the buffer 400 gradually approaches the limit reference plane 500a, and when the feed cylinder 100 drives the processing tool 300 to a position closer to the workpiece, the buffer 400 and the limit The position reference plane 500a is in contact, and as the feed cylinder 100 advances further, the buffer 400 abuts against the limit reference plane 500a. Therefore, when the feed cylinder 100 drives the machining tool 300 to move to the workpiece, when the machining tool 300 is still far away from the workpiece, the feed speed of the machining tool 300 is equivalent to that of the existing CD pattern processing equipment, and when the machining tool 300 is fed to When the position is closer to the workpiece, the buffer force generated by the abutment of the buffer 400 and the limit reference surface 500a slows down the feed speed of the processing tool 300, so that the processing tool 300 is at a lower speed when it contacts the processing surface of the workpiece.

Preferably, the buffer 400 is an elastic member; the elastic force of the buffer 400 enables the buffer 400 to generate a buffer force that slows down the feed speed of the processing tool 300 when it abuts against the limit reference surface 500a. Further, the buffer 400 is an elastic thimble or an elastic pin; one end of the buffer 400 is fixedly connected to the positioning plate 200, and the other end of the buffer 400 abuts against the position-limiting reference plane 500a, and relies on the elastic thimble or the elastic pin.

The feeding cylinder 100 drives the positioning plate 200 to move to one side of the vacuum fixture 700, so that the machining tool 300 moves toward the workpiece. During this process: when the processing tool 300 is still far away from the workpiece, there is a gap between the floating end of the buffer 400 and the limit reference surface 500a, as shown in Figure 4a, the buffer 400 and the limit reference surface 500a have a gap between the processing tool 300. The feed speed will not be affected, and the feed cylinder 100 can drive the processing tool 300 to feed close to the workpiece at a faster feed speed; After connecting, as shown in Figure 4b, the spring element in the buffer 400 provides a buffer force to slow down the feed speed of the processing tool 300; when the feed drive drives the positioning plate 200 to further feed to the positioner 600 against the limit When the reference plane 500a is shown in FIG. 4c, the machining tool 300 is fed to the maximum depth at this time, and the setting of the positioner 600 prevents the feeding cylinder 100 from further feeding.

Compared with the prior art, the CD pattern processing equipment with variable speed feed provided by the utility model adds a limit reference surface 500a and a buffer 400, wherein the buffer 400 passes through the positioning plate 200 so that it is compatible with the feed cylinder 100 Keeping the same movement, when the feed cylinder 100 drives the processing tool 300 to move towards the workpiece, the buffer 400 gradually approaches the limit reference plane 500a, and when the feed cylinder 100 drives the processing tool 300 to a position closer to the workpiece, The buffer 400 is in contact with the limiting reference surface 500a, and with the further advance of the feed cylinder 100, the buffer 400 abuts against the limiting reference surface 500a. Therefore, when the feed cylinder 100 drives the machining tool 300 to move to the workpiece, when the machining tool 300 is still far away from the workpiece, the feed speed of the machining tool 300 is equivalent to that of the existing CD pattern processing equipment, and when the machining tool 300 is fed to When the position is closer to the workpiece, the buffer force generated by the abutment of the buffer 400 and the limit reference surface 500a slows down the feed speed of the processing tool 300, so that the processing tool 300 is at a lower speed when it contacts the processing surface of the workpiece. According to the CD pattern processing equipment with variable speed feeding provided by the utility model, while not affecting the feed speed of the processing tool 300, it can avoid the processing tool 300 from being easily damaged due to excessive force, and at the same time avoid the influence of too large center point of the cutting point on the workpiece surface.
