Description

Technical Field

[0001] The invention relates to the field of metal workpiece processing, and in particular to a device and method for processing burrs on the surface of a metal workpiece. Background Art

[0002] In the field of mechanical processing, burrs will be generated at the entry and exit edges or the intersection of internal fine and deep holes during the machining process of metal workpiece blanks. If not processed, it will cause harm to the subsequent use of the parts and equipment. For example, when it comes into contact with other parts of the equipment, it will scratch other parts and cause damage to the parts. Therefore, burr processing of workpieces is particularly important.

[0003] The burrs generated by existing metal workpiece processing are generally polished manually or by using a shot blasting machine or sand blasting to ensure that the burrs on the surface of the parts can be effectively processed and convenient for the later use of the workpiece. The existing metal workpiece surface burr processing device still has the following defects:

[0004] 1. The existing equipment has low efficiency in manual grinding during use. Although shot blasting and sand blasting are highly efficient, due to the characteristics of the grinding methods, in the actual grinding process, when encountering delicate workpieces, the fine parts of the workpieces cannot be effectively polished, and only a rough grinding can be performed. After the grinding is completed, the fine parts of the workpiece still need to be manually polished for a second time, which makes the efficiency and quality of burr treatment low;

[0005] 2. In actual use, due to the different materials of the workpiece, the burr grinding methods are also different. The existing shot blasting machines and sand blasting machines are based on the material of the workpiece. The particle size of the shot blasting and grit inside the equipment is changed to grind the workpiece. However, in actual use, when encountering workpieces of multiple materials processed at one time, at this time, the only way is to constantly change the particle size of the shot blasting and grit, which reduces the grinding efficiency of the equipment. The workpieces are ground in sequence, making the grinding of the burrs of the workpiece more troublesome.

[0006] Therefore, it is necessary to invent a device and method for processing burrs on the surface of a metal workpiece to solve the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide a device and method for processing burrs on the surface of a metal workpiece, which solves the problems in the prior art that the metal workpiece needs to be manually polished twice and metal workpieces of different materials cannot be polished at the same time by immersing the metal workpiece in iron sand and placing the metal workpiece separately.

[0008] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a device for treating burrs on the surface of a metal workpiece, comprising: a base: a cavity is opened in the base, a connecting shaft is rotatably connected in the cavity, and the connecting shaft penetrates and is connected above the inside of the cavity;

[0015] Preferably, a connecting plate is fixedly connected to one side of the connecting box, an electric telescopic rod is fixedly connected above the connecting plate, and the electric telescopic rod is correspondingly installed on one side of each group of connecting boxes.

[0016] Preferably, the output end of the electric telescopic rod is connected to a baffle, and a rubber pad 2 is fixedly connected below the baffle.

[0017] Preferably, iron sand is placed in the placing box, a metal workpiece is placed in the iron sand, and the iron sand completely wraps the metal workpiece and immerses it inside.

[0045] In the above structure, the box cover 14 and the placement box 13 can be tightly connected by the locking assembly 15 to form a sealed space between the two. Multiple groups of placement boxes 13 can be prepared at the same time to classify and store metal workpieces 23 of different materials.

[0046] like Figure 2 , Figure 6 and Figure 7 As shown, the connection box 8 is fixedly connected with a protrusion 16 on the side away from the guide rod 9, and a convex disc 17 is provided on one side of the protrusion 16. The convex disc 17 is fixedly connected to the connection shaft 3, and the protrusion 16 and the convex disc 17 are in the same horizontal plane.

[0047] In the above structure, the convex disc 17 is driven to rotate by the connecting shaft 3, so that the protrusion of the convex disc 17 will squeeze the protrusion 16, thereby pushing the connecting box 8 to move.

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, a connecting plate 19 is fixedly connected to one side of the connecting box 8, and an electric telescopic rod 18 is fixedly connected above the connecting plate 19.

[0054] A method for treating burrs on the surface of a metal workpiece, comprising a device for treating burrs on the surface of a metal workpiece as described above. The specific treatment steps are as follows:

[0055] Step 1: Place the metal workpiece 23 to be processed into the placement box 13, and add iron sand 22 into the placement box 13. At this time, the box cover 14 and the placement box 13 are firmly locked by the locking assembly 15;

[0056] Step 2: Put the locked placement box 13 into the connection box 8 in turn. At this time, the baffle 20 is moved downward by the electric telescopic rod 18, so that the rubber pad 21 under the baffle 20 fits above the placement box 13, and the placement box 13 is fixed in the connection box 8;

[0057] Step three: Start the belt power structure 4 to drive the connecting shaft 3 to rotate, and the connecting shaft 3 drives the cam disc 17 to rotate. When the protrusion of the cam disc 17 contacts the bump 16, it will push the connecting box 8 to move. When the protrusion of the cam disc 17 rotates away, the spring 11 will push the connecting box 8 to reset. Through the high-speed rotation of the connecting shaft 3, the iron sand 22 inside the placement box 13 swings back and forth, causing friction and grinding on the burrs on the surface of the metal workpiece 23.

[0058] The specific implementation mode of the present invention is as follows Figure 1-7 As shown: the connecting shaft 3 is driven to rotate by the belt power structure 4, and the connecting shaft 3 drives the convex disc 17 to rotate. At this time, when the convex part of the convex disc 17 touches the protrusion 16, the protrusion 16 will be squeezed to push the connecting box 8. At the same time, the slider 7 slides along the slide rail 6, and the guide rod 9 slides into the guide cylinder 10. At the same time, the connecting box 8 squeezes the spring 11. When the convex part of the convex disc 17 is misaligned with the protrusion 16, the spring 11 will reset the connecting box 8. By rotating the connecting shaft 3 in height, this process is repeated to make the connecting box 8 reciprocate, and at the same time, the iron inside the box 13 is placed. The iron sand 22 moves back and forth, and since the metal workpiece 23 is placed in the iron sand 22, the iron sand 22 will grind off the burrs on the surface of the metal workpiece 23 when it moves, and since the iron sand 22 wraps the metal workpiece 23 in an immersion manner, there will be no situation where fine parts cannot be polished, thereby completing the polishing of the workpiece and improving the polishing efficiency. Moreover, it is only necessary to inject iron sand 22 of the required particle size according to the specific requirements of the polishing of the metal workpiece 23 when placing the metal workpiece 23 in the placement box 13, and then repeat the above polishing steps to solve the problem that metal workpieces 23 of different materials cannot be polished at the same time.
