The advantage of a multi-axis turning-milling machining center is that it can realize integrated machining of multiple processes such as turning, milling, and drilling. Its core advantage is that it can complete machining of complex parts with a single clamping, avoiding the error accumulation caused by traditional multi-device transfers, and significantly improving machining accuracy and efficiency. In the prior art, the stacking arrangement of the device increases the operating risk of the device, and the risk of injury when manually moving the workpiece increases.

The output shaft of the servo motor is fixedly connected to the second threaded rod through a coupling, and the sliding block is threadedly sleeved on the second threaded rod. A cleaning mechanism is installed on the top of the turning and milling processing table, which has an automatic cleaning function, improves practicality, and is suitable for promotion. Although this patent solves the above problems, there is still a problem that due to the high risk of multi-axis turning and milling devices, there is a certain risk for workers when placing and removing workpieces. Therefore, a vertical and horizontal seven-axis five-linkage turning and milling compound machining center is proposed to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a vertical and horizontal seven-axis five-link turning and milling compound machining center in view of the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a vertical and horizontal seven-axis five-linkage turning and milling compound machining center, including a machine base, the upper surface of the machine base is fixedly connected to a multi-axis turning and milling mechanism, the inner side of the machine base is provided with a telescopic slot, the rear side surface of the inner wall of the telescopic slot is fixedly connected to an electric push rod, the front free end of the electric push rod is fixedly connected to an operating table, the inner walls of the telescopic slot are slidably connected to support slides on both sides through slide rails, the front side of the machine base is provided with a chip removal device for cleaning metal debris, the upper part of the machine base is provided with a protective device for the safe use of the lifting device, and the rear side of the operating table is provided with a resistance The upper surface of the operating table is slidably connected with a card seat, and telescopic claws are arranged at the front and rear ends of the card seat. A side of the card seat away from the inner wall of the telescopic slot is fixedly connected with a support card shell, and a movable block is arranged on the side of the card seat away from the support card shell. The inner surface of the movable block is hinged with a torsion shaft, and the top of the torsion shaft is fixedly connected with a rotating claw. The front side of the operating table is fixedly connected with an F-shaped pushing plate, and the two sides of the operating table are in contact with the inner wall of the telescopic slot. An elastic telescopic rod 1 is fixedly connected between the inner surface of the operating table and the front side of the contact plate, and the telescopic claw is fixedly connected between the side close to the card seat and the inner surface of the card seat There is an elastic telescopic rod two, and an elastic telescopic rod three is fixedly connected between the side of the movable block close to the card seat and the inner surface of the supporting card shell, and the elastic telescopic rod three passes through the card seat. The metal workpiece is placed on the card seat, and the multi-axis milling mechanism is started to process the workpiece. After the processing is completed, the electric push rod is started, and the electric push rod pushes the operating table to move forward. The operating table drives the workpiece forward through the card seat to move the workpiece away from the multi-axis milling mechanism. The operating table drives the contact plate forward through the elastic telescopic rod one, and the contact plate pushes the supporting slide plate to slide forward. When the supporting slide plate cannot continue to slide forward, the electric push rod continues to push the operating table to extend the elastic telescopic rod one. The support slide plate can provide support for the operating table, so that the operating table can move smoothly for a longer distance. After the workpiece is placed on the holder, the telescopic claw and the rotating claw can clamp the workpiece, pull the telescopic claw and the rotating claw away from the holder, and then release the telescopic claw and the rotating claw. At this time, the telescopic claw and the rotating claw are pulled by the elastic telescopic rod two and the elastic telescopic rod three to approach the workpiece and fit the surface of the workpiece. When processing special-shaped workpieces, after the rotating claw contacts the inclination angle and arc surface of the workpiece surface, it can be rotated in the movable block by the torsion shaft to better fit the shape of the workpiece.

[0006] Preferably, the chip removal device includes a material receiving plate, two sides of the material receiving plate are fixedly connected with side baffles, the upper surface of the operating table is fixedly connected with a connecting rod, the top of the connecting rod is fixedly connected with a chip removal push plate, the chip removal device also includes an inclined plate, the side surface of the side baffle is slidably connected with a sliding frame, the lower surface of the sliding frame is fixedly connected with a scraper, the sliding frame is fixedly connected with a clamping plate on the side close to the F-shaped pushing plate, the lower surface of the F-shaped pushing plate is fixedly connected with a connecting plate, the material receiving plate is fixedly connected to the front side of the machine base, the inclined plate is fixedly connected to the front end of the material receiving plate, the bottom end of the chip removal push plate and the upper surface of the machine base are in contact with each other, and the clamping plate The inner surface of the F-shaped push plate is in contact with each other, and the scraper and the upper surface of the material receiving plate are in contact with each other. When the operating table moves forward, it drives the connecting rod to move forward, and the connecting rod drives the chip removal push plate to move forward. The chip removal push plate pushes the waste chips splashed onto the machine base on both sides of the operating table during processing onto the material receiving plate, thereby automatically and quickly clearing the waste chips near the multi-axis turning and milling mechanism. When the operating table moves forward, it drives the F-shaped push plate to move forward, and the F-shaped push plate drives the card plate to move forward, and the card plate drives the sliding frame to slide forward on the side baffle, and the sliding frame drives the scraper to slide between the material receiving plate and the side baffle and sweeps the metal waste chips accumulated and adhered to the material receiving plate and the side baffle onto the inclined plate.

[0007] Preferably, the protective device includes a protective shell, the top of the protective shell is provided with an observation port, the front side surface of the inner wall of the protective shell is fixedly connected with a telescopic card frame, the inner surface of the telescopic card frame is slidably connected with an L-shaped baffle, and the protective device also includes a positioning plate, the front side surface of the protective shell is fixedly connected with a slide groove frame, the inner surface of the slide groove frame is slidably connected with a sliding shaft, the rear side surface of the sliding shaft is fixedly connected with a convex shaft, the front side surface of the connecting plate is fixedly connected with a top rod, the protective shell is fixedly connected to the upper surface of the base, the protective shell is fixedly connected to the upper surface of the side baffle, the positioning plate and the bottom end of the L-shaped baffle are fixedly connected, the L-shaped baffle and the front side surface of the inner wall of the protective shell are in contact with each other, an elastic telescopic rod four is fixedly connected between the L-shaped baffle and the upper surface of the inner wall of the protective shell, the convex shaft and the positioning plate The inner surfaces are in contact with each other, and an elastic telescopic rod five is fixedly connected between the sliding shaft and the inner surface of the slide groove frame. The protective shell can prevent the multi-axis turning and milling mechanism from affecting the production line and causing safety hazards to the environment and workers when the internal part is damaged. When the multi-axis turning and milling mechanism processes the workpiece, the workpiece processing status can be observed through the observation port, which is convenient for controlling the processing process. When the operating table moves forward and approaches the front end of the protective shell, the L-shaped baffle is lifted to make the L-shaped baffle slide into the telescopic card frame, so as to quickly take out the workpiece. When the F-shaped push plate moves forward, it drives the connecting plate forward, and the connecting plate drives the push rod forward. When the push rod contacts the bottom of the sliding shaft and pushes it into the slide groove frame, the sliding shaft drives the convex shaft away from the positioning plate. After the positioning plate loses the limit of the convex shaft, the elastic telescopic rod four quickly pulls the L-shaped baffle upward, thereby quickly opening the protective shell.

[0008] The present invention adopts the above technical solution to bring the following beneficial effects: 1. The vertical and horizontal seven-axis five-linkage turning and milling compound machining center uses a clamping seat to drive the workpiece forward and away from the multi-axis turning and milling mechanism to prevent workers from close contact with the multi-axis turning and milling mechanism, thereby improving safety in use.

The telescopic claw and rotating claw elastically fit the workpiece surface to clamp workpieces of different sizes, thereby improving the applicability of clamping. The rotating claw fits the shape of the workpiece better through rotation, further improving the applicability and stability of clamping.

[0009] 2. The vertical and horizontal seven-axis five-linkage turning and milling compound machining center has a chip pusher plate that pushes the waste chips splashed onto the machine base on both sides of the operating table during machining to the receiving plate, thereby automatically and quickly removing the waste chips near the multi-axis turning and milling mechanism, improving the efficiency and safety of waste chip cleaning, and preventing waste chips from getting stuck in the multi-axis turning and milling mechanism and affecting machining efficiency.

[0010] 3. The scraper of this vertical and horizontal seven-axis five-link turning and milling compound machining center slides between the receiving plate and the side baffle and sweeps the metal waste accumulated and adhered to the receiving plate and the side baffle onto the inclined plate. Finally, the waste slides to the bottom of the device through the inclined plate, which is convenient for the staff to collect and process.

[0011] 4. The protective shell of the vertical and horizontal seven-axis five-linkage turning and milling compound machining center can prevent the multi-axis turning and milling mechanism from being damaged and affecting the production line and causing safety hazards to the environment and workers. When the multi-axis turning and milling mechanism is processing the workpiece, the workpiece processing status can be observed through the observation port, which is convenient for controlling the processing process. The L-shaped baffle is lifted and slides into the telescopic card frame to quickly take out the workpiece, greatly reducing the harm of the device while improving work efficiency.

[0012] 5. For the vertical and horizontal seven-axis five-link turning and milling compound machining center, after the positioning plate loses the limit of the convex shaft, the elastic telescopic rod four quickly pulls the L-shaped baffle upward, thereby quickly opening the protective shell without manual operation, further improving work efficiency.
