Description

Technical Field

[0001] The utility model belongs to the technical field of burr removal, and in particular relates to a burr removal device for machining mechanical parts. Background Art

[0002] Due to the process limitations of mechanical processing, it is easy to produce thorns on the edges of parts, which are called burrs in the mechanical industry. Burrs have a great impact on the appearance and use of products. They should be avoided as much as possible during the processing. If they cannot be avoided, there must be a subsequent deburring process to ensure the beauty and practicality of the product.

[0003] Commonly used deburring methods include roller grinding deburring. However, in the process of removing burrs from parts by existing roller grinding, the edges of the parts need to be ground separately. The burrs on the contours of the openings on the surfaces of plate-like parts need to be deburred separately after the edges of the parts are ground, which leads to low operating efficiency.

[0004] Therefore, a burr removal device for machining mechanical parts is designed to solve the technical problem in the prior art that the burrs on the edge of a plate-like part and the outline of an opening cannot be removed simultaneously. Utility Model Content

[0054] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0055] Commonly used deburring methods include roller grinding deburring. However, in the process of removing burrs from parts by existing roller grinding, the edges of the parts need to be ground separately. The burrs on the contours of the openings on the surfaces of plate-like parts need to be deburred separately after the edges of the parts are ground, which leads to low operating efficiency.

[0056] In order to solve the above technical problems, in at least one embodiment, a burr removal device for machining mechanical parts is provided, comprising: an edge grinding mechanism 2 and a plane grinding mechanism 3 arranged on a base 4; wherein the edge grinding mechanism 2 is arranged on one side of the part 5, and is suitable for removing burrs from the edge of the part 5; and the plane grinding mechanism 3 is arranged above the part 6, and operates synchronously with the edge grinding mechanism 2, and is suitable for removing burrs from the hole contour machined on the surface of the part 6.

[0057] By setting up an edge grinding mechanism 2 and a plane grinding mechanism 3, the two are connected by a driving mechanism 1. When the processed part 6 needs to be deburred, the two are driven to operate synchronously by the driving mechanism 1, so that the burrs on the edge of the part 6 can be removed while the burrs on the surface opening contour can be removed, thereby improving the burr removal efficiency and saving working time.

[0058] In some embodiments, Figures 1 to 4 As shown, the part 6 that needs to be deburred is placed on the upper end surface of the part grinding table 5, and the part 6 is manually pushed to move on the upper end surface of the part grinding table 5. At this time, the motor 10 is started, and its output end drives the driving shaft 11 to rotate, thereby driving the driving gear 12 fixed on the driving shaft 11 to rotate, and the driving gear 12 is engaged with the first gear 23 fixed on the edge grinding shaft 21, and the two form a staggered transmission, driving the edge grinding shaft 21 to rotate, so that the several edge grinding pieces 22 set on the edge grinding shaft 21 are rotated to remove the edge burrs of the part 6, and at least two edge grinding pieces 22 are provided, and one of the edge grinding pieces 22 is connected to the edge grinding shaft 21 by a coaxial reversing mechanism 25 (the coaxial reversing mechanism is a prior art, and its specific structure is not repeated here), so that the edge grinding piece 22 rotates in the opposite direction to the other edge grinding piece 22, so that the burrs on the upper and lower edge lines of one end surface of the part 6 are removed.

[0059] In some embodiments, Figures 3 to 6 As shown, the rotation of the edge grinding shaft 21 drives the second gear 24 fixed thereon to rotate, and the second gear 24 is meshed with the driven gear 311, and the two form a staggered transmission, driving the plane grinding shaft 31 to rotate. Inside the plane grinding box 30, a plurality of short shafts 32 are arranged on the horizontal bearing above the part 6, and the short shafts 32 are connected by a chain 33, and one of the short shafts 32 is connected to the plane grinding shaft 31 by the chain 33, so that when the plane grinding shaft 31 rotates, the short shafts 32 and the first plane grinding parts 34 fixed on the short shafts 32 are driven to rotate, thereby removing the edge burrs of the outer contour of the opening on the end face of the part 6.

[0060] In some embodiments, Figure 6 to Figure 7 As shown, a number of deflection plates 37 corresponding to the short shaft 32 is arranged inside the base 4, and a second plane grinding member 38 is arranged on each deflection plate 37 to remove the edge burrs of the outer contour of the opening of the lower end surface of the part 6;

[0061] The deflection plate 37 is connected to the connecting rod 36 by a bearing, and the connecting rod 36 is fixed to the auxiliary grinding table 35, so that when the second plane grinding piece 38 encounters the protrusion on the part 6, it can follow the deflection plate 37 to deflect without hindering the movement of the part 6, and a reset spring 38 is arranged on the lower end surface of the deflection plate 37. The thrust of the reset spring 38 pushes the deflection plate 37 and the second plane grinding piece 38 to move upward, so that the second plane grinding piece 38 is always in contact with the lower end surface of the part 6 to ensure the grinding effect;

[0062] The driving method of the second plane grinding member 38 includes but is not limited to connecting it to the deflection plate 37 through a connecting rod, and connecting the connecting rod and the corresponding short shafts 32 through a belt, so that the connecting rod is driven to rotate when the short shaft 32 rotates.

[0063] In some embodiments, in order to prevent burrs from flying during the process of removing burrs from the edge of the part 6, a protective shell 20 is set on the base 4, which is sleeved on the outside of each edge grinding piece 22, and a cyclone separator 43 and an exhaust pipe 41 are set inside the base 4. One end of the exhaust pipe 41 passes through the protective shell 20, and the other end is connected to the feed port of the cyclone separator 43. The exhaust fan 40 connected to the cyclone separator 43 is started, and the flying burrs intercepted by the protective shell 20 are introduced into the cyclone separator 43 through the exhaust pipe 41 for separation, and finally discharged through the discharge port of the cyclone separator 43 to the burr collection bin 42 for recovery.

[0064] To summarize, by providing an edge grinding mechanism and a plane grinding mechanism, the two are connected by a driving mechanism. When it is necessary to deburr the processed parts, the two are driven synchronously by the driving mechanism, so that the burrs on the edge of the parts can be removed while the burrs on the opening contours on the upper and lower surfaces can be removed, thereby improving the burr removal efficiency and saving working time.
