Description

Technical Field

[0001] The utility model relates to the technical field of burr removal, in particular to a surface deburring device for metal casting processing. Background Art

[0002] In the production process of metal castings, surface burrs are a common problem. These burrs are caused by uneven material shrinkage when the casting cools and solidifies in the mold. The presence of burrs not only affects the appearance quality of the casting, but may also have an adverse effect on the assembly accuracy and performance of the casting. Therefore, after the casting is completed, the casting usually needs to be surface treated to remove these burrs.

[0003] However, for example, when grinding burrs on the outside of pipe fittings, some devices have poor adaptability to the size of the castings and find it difficult to process pipe fittings of different diameters. In addition, conventional grinding devices only have the function of grinding in a single direction, such as rotary grinding around the outer side of the pipe fitting, and no horizontal grinding. Therefore, unidirectional grinding may effectively grind the burrs in that direction, but the effect of removing burrs in other directions is poor. Therefore, a surface deburring device for metal casting processing is needed to solve the existing deficiencies. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] As Figure 1-5 shown, the utility model provides a kind of technical scheme: a kind of surface deburring device for metal casting processing, including base 1 and pipe 2, the top end of base 1 is movably connected with bottom plate 3, and the top end of bottom plate 3 is fixedly connected with a group of symmetrical support plate 4, the opposite side of support plate 4 is movably connected with support cylinder 5, pipe 2 penetrates support cylinder 5, and the both ends of support cylinder 5 are provided with polishing mechanism 6, the top end of bottom plate 3 is provided with driving mechanism 7, and driving mechanism 7 is fixedly connected with the middle part of support cylinder 5, the inside of base 1 is provided with reciprocating mechanism 8, and reciprocating mechanism 8 is connected with the bottom end of bottom plate 3.

[0027] As Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the grinding mechanism 6 includes a grinding sheet 601, a connecting rod 602, a return spring 603 and a push rod 604. The grinding sheet 601, the connecting rod 602, the return spring 603 and the push rod 604 are all distributed in a circular array. One end of the connecting rod 602 is fixedly connected to the back side of the grinding sheet 601, and the push rod 604 is fixedly connected to the other end of the connecting rod 602. The return spring 603 is sleeved on the outside of the connecting rod 602. The grinding sheets 601 are all located on the outside of the pipe 2, and the inner side of the grinding sheet 601 is in contact with the outside of the pipe 2. The connecting rod 602 passes through the wall of the support tube 5 and is movably connected to the wall of the pipe. The return spring 603 is sleeved on the outside of the connecting rod 602. One end is fixedly connected to the back side of the grinding disc 601, and the other end of the return spring 603 is fixedly connected to the inner side of the support tube 5. The grinding mechanism 6 also includes an adjusting ring 605 and a push ring 606. The push ring 606 is sleeved on the outside of the support tube 5, and the push ring 606 is movably connected to the support tube 5. The end of the push ring 606 close to the push rod 604 is constructed with a beveled surface, and the end of the push rod 604 is fitted with the beveled surface of the push ring 606. The adjusting ring 605 is sleeved on the outside of the support tube 5. A group of symmetrical threads are opened on the outside of the support tube 5, and the adjusting ring 605 is threadedly connected to the support tube 5. The opposite sides of the adjusting ring 605 and the push ring 606 are fitted with each other.

[0028] The adjusting ring 605 is rotated to move the adjusting ring 605 toward the pushing ring 606. The beveled surface of the pushing ring 606 fits with the end of the pushing rod 604, thereby making the pushing rod 604 move outward. Therefore, under the action of the connecting rod 602, the grinding plates 601 move away from each other, the return spring 603 is compressed and shortened, and then the pipe 2 is passed through the supporting tube 5 and the grinding plate 601. Then the adjusting ring 605 is rotated. Under the action of the return spring 603, the inner side of the grinding plate 601 fits with the outer side of the pipe 2, thereby facilitating the installation of the pipe 2. At the same time, according to the diameter of the pipe 2, under the action of the return spring 603, the grinding plate 601 is always fit with the outer surface of the pipe 2, so that the friction between the outer side of the pipe 2 and the grinding plate 601 is maintained at an appropriate level, which is conducive to burr grinding, but avoids excessive friction that causes the temperature of the pipe 2 to rise.

[0029] like Figure 1 and Figure 2 As shown, the driving mechanism 7 includes a gear ring 701, a gear 702 and a servo motor 703. The gear ring 701 is sleeved on the middle part of the support tube 5 and is fixedly connected to the support tube 5. The gear 702 is movably connected to the top of the base plate 3 through a rotating shaft, and the gear ring 701 is meshed with the gear 702. The servo motor 703 is fixedly connected to the top of the base plate 3, and the output end of the servo motor 703 is fixedly connected to the rotating shaft of the gear 702.

[0030] Start the servo motor 703 to drive the gear 702 to rotate. Since the gear 702 is engaged with the gear ring 701, the gear ring 701 and the support tube 5 are controlled to rotate synchronously. The pipe 2 moves horizontally through other traction movements. At this time, the grinding sheet 601 rotates around the axis of the pipe 2, so that the inner side of the grinding sheet 601 is used to effectively grind the burrs on the outer side of the moving pipe 2.

[0031] like Figure 1 and Figure 4 As shown, the reciprocating mechanism 8 includes a connecting plate 801, a cam 1 802, a cam 2 803, a rotary rod 1 804 and a rotary rod 2 805. The connecting plate 801 is fixedly connected to the bottom end of the base plate 3. The connecting plate 801 is located on the opposite sides of the cam 1 802 and the cam 2 803, and both sides of the connecting plate 801 are in contact with the outer sides of the cam 1 802 and the outer sides of the cam 2 803. The rotary rod 1 804 passes through the axis of the cam 1 802 and is fixedly connected to the cam 1 802. The rotary rod 2 805 passes through the axis of the cam 2 803 and is fixedly connected to the cam 2 803. The cam 1 802 passes through the axis of the cam 1 The rotary rod 1 804 is movably connected to the inside of the base 1, and the cam 2 803 is movably connected to the inside of the base 1 through the rotary rod 2 805. When the distal end of the cam 1 802 is in contact with the side of the connecting plate 801, the proximal end of the cam 2 803 is in contact with the other side of the connecting plate 801. The outer sides of the rotary rod 1 804 and the rotary rod 2 805 are fixedly connected with a synchronous wheel 9, and the outer side of the synchronous wheel 9 is provided with a synchronous belt 10. The synchronous wheel 9 and the synchronous belt 10 constitute a belt transmission structure. The interior of the base 1 is fixedly connected with a servo motor 2 11, and the output end of the servo motor 2 11 is fixedly connected to the bottom end of the rotary rod 1 804.

[0032] Start the servo motor 2 11, drive the rotary rod 1 804 to rotate inside the base 1, so that the cam 1 802 rotates around the rotary rod 1 804, and under the action of the synchronous wheel 9 and the synchronous belt 10, drive the cam 2 803 to rotate around the rotary rod 2 805. Since the connecting plate 801 is on the opposite side of the cam 1 802 and the cam 2 803, when the cam 1 802 and the cam 2 803 rotate in the same direction, the cam 1 802 rotates from the proximal end to the distal end. The cam 2 803 rotates from the distal end to the proximal end, thereby making the connecting plate 801 fit together with the connecting plate 801, and in turn making the connecting plate 801 move back and forth inside the base 1, thereby driving the bottom plate 3 to move back and forth on the top of the base 1, so that the support tube 5 rotates and moves back and forth at the same time, making it convenient for the grinding sheet 601 to give it a horizontal reciprocating motion while grinding around the axis of the pipe 2, thereby grinding the burrs on the pipe 2 in the second direction, and improving the grinding effect of the burrs on the outside of the pipe 2.

[0033] Working principle: in use, first, rotate the adjusting ring 605, so that the adjusting ring 605 moves towards the push ring 606, the inclined surface of the push ring 606 is in contact with the end of the push rod 604, so that the push rod 604 moves outward, so that the polishing pieces 601 move away from each other under the action of the connecting rod 602, and the reset spring 603 is compressed and shortened, then the pipe 2 penetrates the support cylinder 5 and the polishing piece 601, then rotate the adjusting ring 605, the inner side of the polishing piece 601 is in contact with the outer side of the pipe 2 under the action of the reset spring 603; then, start the servo motor one 703, drive the gear 702 to rotate, since the gear 702 is in mesh with the gear ring 701, so as to control the synchronous rotation of the gear ring 701 and the support cylinder 5, the pipe 2 moves horizontally through other traction movement, at this time the polishing piece 601 rotates around the axis of the pipe 2, so as to effectively polish the burrs on the outer side of the moving pipe 2 by the inner side of the polishing piece 601; in addition, start the servo motor two 11, drive the rotating rod one 804 to rotate in the inside of the base 1, so that the cam one 802 rotates around the rotating rod one 804, and drive the cam two 803 to rotate around the rotating rod two 805 under the action of the synchronous wheel 9 and the synchronous belt 10, since the connecting plate 801 is on the opposite side of the cam one 802 and the cam two 803, when the cam one 802 and the cam two 803 rotate in the same direction, the cam one 802 rotates from the near center end in contact with the connecting plate 801 to the far center end in contact with the connecting plate 801, and the cam two 803 rotates from the far center end in contact with the connecting plate 801 to the near center end in contact with the connecting plate 801, in turn, the connecting plate 801 moves back and forth in the inside of the base 1, so as to drive the bottom plate 3 to move back and forth on the top end of the base 1, so that the support cylinder 5 rotates and moves back and forth at the same time.
