Description

Technical Field

[0001] The present invention relates to the technical field of casting part grinding, and specifically refers to a flat grinding mechanism for casting parts. Background Art

[0002] After the casting is poured, there will be a lot of flash and risers on it, which are not required for the final product. At this time, the casting is still a semi-finished product, and these flash and risers must be removed to obtain the finished product. If it is a cast iron part, it is generally directly knocked off with a sledgehammer, and a steel casting needs to be cut with gas cutting. However, there will still be a small piece left on the casting after knocking off and cutting, and then the casting grinder is needed to grind it.

[0003] The grinding of casting parts generally uses an electric grinding machine, which has a large diameter and a small hand-held grinding machine. The excess flash and risers on the casting parts are ground clean little by little to make the casting parts flat and beautiful. The entire grinding process takes a long time and requires a high level of physical strength.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Embodiment 1

[0028] As attached Figure 1 and attached Figure 4 As shown, a casting surface grinding mechanism comprises a lifting platform 1, wherein a receiving platform 2 is provided inside the lifting platform 1, a placing groove 3 is rotatably installed inside the upper side of the receiving platform 2, a mounting frame 4 is installed at the upper edge of the lifting platform 1, a horizontal threaded shaft 5 is rotatably installed on the inner side of the upper part of the mounting frame 4, a motor 6 for driving the threaded shaft 5 is installed on one side of the mounting frame 4, a moving block 7 is threadedly installed on the outer side of the threaded shaft 5, an inverted U-shaped frame 12 is installed on the lower side of the moving block 7, and a positioning shaft is slidably passed through the two side walls of the inverted U-shaped frame 12 10, one end of the positioning shaft 10 is rotatably connected to the mounting frame 4 and the axial direction is parallel to the axial direction of the threaded shaft 5, the outer side of the positioning shaft 10 located on the inner side of the inverted U-shaped frame 12 is sleeved with a grinding wheel 13, a gear 9 is installed on the outer side of one end of the threaded shaft 5, a gear 2 11 matched with the gear 9 is provided on the outer side of the positioning shaft 10, multiple groups of limit strips 14 are installed on the outer side of the positioning shaft 10, the inner wall of the grinding wheel 13 cooperates with the multiple groups of limit strips 14 to limit sliding, and a control switch 27 connected with the motor 6 is installed on the upper side of the lifting platform 1.

[0029] With the above structure, the casting is placed in the placement groove 3 for positioning. By rotating the placement groove 3 inside the receiving platform 2, the position of the casting is adjusted. The first motor 6 is started through the control switch 27. The first threaded shaft 5 is driven to rotate by the first motor 6. The first gear 9 on the outer side of the first threaded shaft 5 meshes with the second gear 11 to drive the positioning rotating shaft 10 to rotate. The grinding wheel 13 can be driven to rotate by the multiple groups of limiting strips 14 limiting inside the grinding wheel 13. The casting is ground by the grinding wheel 13. When the first threaded shaft 5 rotates, it drives the moving block 7 to move horizontally. The inverted U-shaped frame 12 and the grinding wheel 13 inside it are driven by the moving block 7 to move horizontally to comprehensively grind the casting. The specific structure is as follows:

[0030] Combined with the attached Figure 1 and the attached Figure 4 As shown, the positioning rotating shaft 10 and the multiple groups of limiting strips 14 can rotate inside the inner sides of the two side walls of the inverted U-shaped frame 12. A limiting rod 8 slides through the upper side of the moving block 7. One end of the limiting rod 8 is connected to the mounting frame 4 and the axial direction of the limiting rod 8 is parallel to the axial direction of the first threaded shaft 5. Reversing switches 16 connected to the first motor 6 are respectively arranged on the outer walls of the two sides of the inverted U-shaped frame 12. A limiting block 15 is installed at one end of the positioning rotating shaft 10.

[0031] With the above structure, the inverted U-shaped frame 12 does not contact the positioning rotating shaft 10 and the multiple groups of limiting strips 14, and can drive the grinding wheel 13 to move horizontally freely. The position of the moving block 7 is restricted by the limiting rod 8 to prevent the moving block 7 from rotating with the first threaded shaft 5 and also prevent the inverted U-shaped frame 12 from rotating to contact the positioning rotating shaft 10 and the multiple groups of limiting strips 14. When the inverted U-shaped frame 12 moves to both ends of the positioning rotating shaft 10, the reversing switch 16 is squeezed by the limiting block 15 and the mounting frame 4 to reverse the first motor 6, so that the moving block 7 moves in the opposite direction, realizing the reciprocating movement of the grinding wheel 13.

[0032] Combined with the attached Figure 2 As shown, two groups of push rods 23 slide through the adjacent two sides of the placement groove 3 respectively. A positioning plate 24 is connected between the ends of the two groups of push rods 23 located inside the placement groove 3 on the same side. A pulling plate 25 is connected between the other ends of the two groups of push rods 23 on the same side. A spring 26 is installed between the outside of the placement groove 3 and the pulling plate 25, and the spring 26 is sleeved on the outside of the push rod 23.

[0033] With the above structure, when the casting is placed inside the placement groove 3, the two pulling plates 25 are moved in a direction away from the placement groove 3 to compress the spring 26, and the positioning plate 24 is moved close to the side wall of the placement groove 3. After the casting is placed inside the placement groove 3, the two pulling plates 25 are released. The positioning plate 24 is pushed by the resilience of the spring 26 in the direction of the casting. The casting is positioned by the cooperation of the two positioning plates 24 and the inner walls of the two sides of the placement groove 3.

A control switch 27 connected to the second motor 19 and the third motor 22 is installed on the upper side of the lifting table 1.

[0036] With the above structure of Embodiment 2, in order to adjust the casting to be in contact with the grinding wheel 13, the second motor 19 is started through the control switch 27. The second threaded shaft 18 is driven to rotate by the second motor 19. The lifting table 1 is driven to move upward outside the receiving table 2 through the cooperation of the second threaded shaft 18 with the thread, and the casting is adjusted to be in contact with the grinding wheel 13, so that the grinding wheel 13 can grind the casting. In order to ensure that the upper side of the casting is fully ground, the third motor 22 is started through the control switch 27. The placement groove 3 is driven to rotate inside the receiving table 2 by the third motor 22, so that the casting rotates under the grinding wheel 13, and each position of the casting is ground under the grinding wheel 13.
