[0002] The piston is a very common automotive part and is the first important component to transmit the explosive force of fuel to the outside. Existing pistons are usually cast from molten aluminum. After the casting process, the blank needs to be partially cut. Therefore, a cast aluminum piston blank cutting device is needed to cut the cast piston blank.

[0003] For example, Chinese patent number CN216990184U discloses a cast aluminum piston blank cutting device, which includes a frame, a cover plate, a slide plate, a fixing mechanism, a receiving mechanism and a cutting mechanism. The cover plate is rotatably connected to the frame, the frame is provided with two slide grooves, the slide plates are slidably connected to the two slide grooves, the fixing mechanism is fixedly connected to the slide plate, the cutting mechanism is fixedly connected to the frame, and the receiving mechanism includes a first motor, a gear and a rack. The first motor is fixedly connected to the frame, the output end of the first motor is fixedly connected to the gear, the rack is fixedly connected to the slide plate, and the gear and the rack are meshed. Through the above-mentioned structural arrangement, it is possible to prevent sparks from flying and causing injuries when cutting the piston blank;

[0004] In the prior art, although the piston can be processed by placing it in a relatively closed space to ensure processing safety, during the processing, the piston blank needs to be placed under the cutting machine before processing, which is dangerous. Utility Model Content

[0031] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0032] like Figure 1-4 As shown, a cutting device for main pump piston processing includes a processing table 1, a protective cover 2 is fixedly assembled and connected above the processing table 1, an opening is provided on one side of the protective cover 2, a cutting machine 3 is assembled and connected above the inner side of the protective cover 2, a first telescopic cylinder 31 is assembled and connected between the upper side of the cutting machine 3 and the protective cover 2, a first slide rail 41 and a second slide rail 42 are assembled and connected above the processing table 1, the first slide rail 41 is assembled and connected to the first cutting seat 411, the second slide rail 42 is assembled and connected to the second cutting seat 421, the first cutting seat 411 and the second cutting seat 421 are staggered up and down, and the protective cover 2 is fixedly assembled and connected to the positioning plates 5 on both sides of the cutting machine 3.

[0033] The technical solution of this embodiment is adopted, and the main pump piston blank is placed on the upper side of the first cutting seat 411 and the second cutting seat 421 for processing, and then the first cutting seat 411 and the second cutting seat 421 are controlled to move by controlling the operation of the first slide rail 41 and the second slide rail 42. When the first cutting seat 411 is located directly below the cutting machine 3, the second cutting seat 421 is located outside the protective cover 2, so that when one main pump piston is processed, the next main pump piston to be processed can be placed. The first telescopic cylinder 31 is used to control the cutting machine 3 to move up and down. Because the heights of the first cutting seat 411 and the second cutting seat 421 are different, the cutting machine 3 is controlled to move by controlling the working height of the first telescopic cylinder 31, so that the main pump piston located above different cutting seats is cut. The positioning plate 5 is used to position the two sides of the main pump piston, so that the position of the main pump piston is fixed when the main pump piston is cut.

[0034] Reference Figure 4 A sealing plate 21 is slidably connected to an opening on one side of the protective cover 2. Both sides of the sealing plate 21 are slidably connected to the protective cover 2. A top plate 22 is fixedly connected above the sealing plate 21, and a lifting mechanism 23 is assembled and connected to one side of the top plate 22. In this embodiment, the sealing plate 21 is used to seal the opening of the protective cover 2. During the process of the cutting machine 3 processing the blank of the main pump piston, the sealing plate 21 is located below the protective cover 2 to prevent sparks from splashing out of the protective cover 2. The top plate 22 is used to prevent the sealing plate 21 from falling directly from the top of the protective cover 2. The lifting mechanism 23 is used to control the raising and lowering of the sealing plate 21.

[0035] Reference Figure 2 The lifting mechanism 23 includes a second cylinder 231 fixedly connected to the upper side of the processing table 1. The output end of the second cylinder 231 is fixedly assembled and connected to the top plate 22. In this embodiment, the second cylinder 231 is used to control the lifting and lowering of the sealing plate 21. When the position of the first cutting seat 411 or the second cutting seat 421 moves, the sealing plate 21 is moved upward by moving the output end of the second cylinder 231 upward, allowing the first cutting seat 411 or the second cutting seat 421 to move through the sealing plate 21.

[0036] Reference Figure 3 A third cylinder 61 is fixedly assembled and connected between the positioning plate 5 and the protective cover 2. The positioning plate 5 is located outside the second cutting seat 421. In this embodiment, the third cylinder 61 is used to control the positioning plate 5 to position the main pump piston. The first cutting seat 411 and the second cutting seat 421 are smaller than the main pump piston blank. When the first cutting seat 411 moves to directly below the cutting machine 3, the output end of the third cylinder 61 drives the positioning plate 5 to move, fixing both sides of the main pump piston blank.

[0037] Reference Figure 2The processing table 1 has a discharge port directly below the cutting machine 3, and a material receiving frame 7 is assembled and connected to the lower side of the processing table 1. In this embodiment, the material receiving frame 7 is used to collect the debris generated by cutting to prevent the debris from accumulating on the upper side of the processing table 1. The material receiving frame 7 can be removed from the lower side of the processing table 1 to facilitate the disposal of the debris.

[0038] Reference Figure 2-3 The first cutting seat 411 and the second cutting seat 421 are both in an N-shape, and ribs 43 are fixedly connected to the upper outer sides of the first cutting seat 411 and the second cutting seat 421. In this embodiment, the first cutting seat 411 and the second cutting seat 421 will not interfere with each other when they move. The first cutting seat 411 and the second cutting seat 421 are in an N-shape, and the first cutting seat 411 can pass under the second cutting seat 421. The ribs 43 are used to abut one side of the main pump piston blank. When the first cutting seat 411 moves inward to the inner side of the main pump piston blank and contacts the side wall of the protective cover 2, the front and rear sides of the main pump piston blank are fixed.

[0039] Reference Figure 2 : An observation window 24 is provided on one side of the protective cover 2.

[0040] In this embodiment, the observation window 24 is made of a transparent material and is used to observe the processing of the main pump piston blank by the cutting machine.

[0041] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
