[0002] Castings are metal parts formed by pouring molten iron into a mold cavity and then cooling it. They are low-cost and can produce complex shapes. However, the problem is that after casting, the outer wall of the casting has protrusions such as gates and risers, as well as a large number of burrs, which require grinding before subsequent processing.

[0003] In the existing technology, although casting grinding is assisted by mechanical equipment, it still relies on manual operation, which has certain errors. In addition, the grinding effects of different batches of parts vary from person to person, and the processing consistency is poor. Utility Model Content

[0005] The utility model solves the above-mentioned technical problem with the following technical solution: a casting burr grinding device, comprising a platform, two mounting brackets symmetrically arranged on the platform, both mounting brackets being provided with mutually parallel slide grooves, a slide rail seat being arranged between the two mounting brackets and slidably positioned at both ends in the slide grooves, a slide table being slidably mounted in the slide rail seat, a grinding roller and a follower roller being sequentially arranged on one side of the slide table facing the top surface of the platform along the length direction of the slide rail seat;

[0006] Two groups of clamping components are fixedly installed on the top surface of the platform. The two groups of clamping components are located below the slide rail seat and are arranged in sequence along the length direction of the slide rail seat.

[0007] The beneficial effects of the utility model are as follows: the two groups of clamping assemblies respectively clamp the finished casting and the casting to be polished, the following roller contacts the finished casting, and the polishing roller contacts the casting to be polished, and then the following roller moves along with the outer contour of the casting to push the slide rail seat up and down, thereby driving the polishing roller to move up and down, and the polishing roller polishes the casting to be polished, realizing following-form polishing, improving polishing efficiency, and making the polishing effects of parts from different batches more stable and consistent.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] The beneficial effect of adopting the above further solution is that rotating the turntable can drive the slide rail seat to change its direction, thereby achieving side grinding of the casting.

[0012] Furthermore, a limit screw is threadedly mounted on the outer wall of the mounting frame, and one end of the limit screw extends into the inner side of the mounting frame and abuts against the outer wall of the turntable.

[0013] The beneficial effect of adopting the above further solution is that when the limit screw is turned, the limit screw abuts against the outer wall of the turntable to prevent rotation, thereby achieving fixation.

[0017] The telescopic end of the second telescopic rod points to the top surface of the platform and is fixedly connected to a second bracket, and the follower roller is rotatably mounted on the second bracket.

[0018] The beneficial effect of adopting the above further solution is: the height of the grinding roller is adjusted by the first telescopic rod, and the height of the follow-up roller is adjusted by the second telescopic rod to adapt to different castings.

[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0030] Example 1

[0031] like Figures 1 to 3 As shown, a casting burr grinding device includes a platform 1, two mounting frames 2 are symmetrically arranged on the platform 1, and the two mounting frames 2 are each provided with a mutually parallel slide 3, a slide rail seat 4 is mounted between the two mounting frames 2 and slidably located in the slide 3 at both ends, a slide 5 is slidably installed in the slide rail seat 4, and a grinding roller 6 and a follower roller 7 are sequentially arranged on the side of the slide 5 facing the top surface of the platform 1 along the length direction of the slide rail seat 4;

[0032] Two groups of clamping assemblies 8 are fixedly installed on the top surface of the platform 1 . The two groups of clamping assemblies 8 are located below the slide rail seat 4 and are arranged in sequence along the length direction of the slide rail seat 4 .

[0033] The beneficial effects of this embodiment are: the two groups of clamping assemblies 8 respectively clamp the finished casting and the casting to be polished, the following roller 7 contacts the finished casting, and the grinding roller 6 contacts the casting to be polished, and then the following roller 7 moves along the outer contour of the casting to push the slide rail seat 4 up and down, thereby driving the grinding roller 6 to move up and down, and the grinding roller 6 polishes the casting to be polished, realizing following-form grinding, improving grinding efficiency, and the grinding effect of parts from different batches is more stable and consistent.

[0034] Specifically, after the casting is completed, the casting surface has protruding useless parts such as the pouring cup and riser, as well as a large number of burrs, which need to be polished. If the pouring cup and riser are too large, the staff can first break off the upper part and then polish the remaining part on the casting;

[0035] When grinding is required, the two sets of clamping assemblies 8 respectively clamp the finished casting and the casting to be ground, and the surface to be ground faces the slide rail seat 4. Then the slide 5 is started, and the slide 5 drives the grinding roller 6 and the following roller 7 to move simultaneously. The following roller 7 has no power source, and the grinding roller 6 has a grinding power source and keeps rotating all the time. After the following roller 7 contacts the outer contour of the finished casting, it follows the outer contour of the finished casting and moves in accordance with the contour.

[0036] When the following roller 7 rises following the contour of the finished casting, the following roller 7 pushes the slide 5 to rise in level, and the slide 5 drives the slide rail seat 4 to slide and rise in the slide groove 3. When the following roller 7 descends following the contour of the finished casting, the slide rail seat 4 slides and descends in the slide groove 3 under the action of gravity, driving the slide 5 to descend, thereby driving the grinding roller 6 on the other side to grind according to the contour, ensuring that the grinding effect of multiple batches of castings is the same.

[0037] On the basis of this embodiment, the cross section of the slide 5 is an inverted T-shape, and a plurality of rollers are installed on the side wall of the end of the slide 5 extending into the slide rail seat 4 to reduce the sliding friction resistance of the slide 5.

[0038] Example 2

[0039] like Figure 1 As shown, preferably, on the basis of embodiment 1, the mounting frame 2 is fixedly mounted on the platform 1, and a turntable 9 is rotatably mounted in the mounting frame 2, and the two turntables 9 are arranged opposite to each other and their central axes coincide with each other;

[0040] The end surfaces of the two turntables 9 on one side are respectively provided with mutually parallel slide grooves 3, and the length direction of the slide grooves 3 is perpendicular to the central axis of the turntable 9. The two ends of the slide rail seat 4 are respectively slidably located in the two slide grooves 3.

[0041] The beneficial effect of adopting the preferred solution in the above embodiment is that rotating the turntable 9 can drive the slide rail seat 4 to change its direction, thereby achieving side grinding of the casting.

[0042] Specifically, the casting is clamped on the clamping assembly 8. When the side of the casting needs to be polished, the two turntables 9 are rotated, and the turntables 9 drive the two slide grooves 3 to change the direction of the length direction, thereby changing the sliding direction of the slide rail seat 4.

[0043] It should be noted that after rotating the turntable 9, the position of the slide groove 3 should always be above or obliquely above the clamping assembly 8, so that the slide rail seat 4 can slide downward under the action of gravity;

[0044] If the slide 3 is laid flat to a position where the length direction is parallel to the top surface of the platform 1, the slide rail seat 4 loses the effect of gravity. During the grinding process, the staff needs to manually push the slide rail seat 4 closer to the casting on the clamping assembly 8 to facilitate grinding.

[0045] Example 3

[0046] like Figure 1 As shown, preferably, based on Examples 1-2, a limit screw 10 is threadedly installed on the outer wall of the mounting frame 2, and one end of the limit screw 10 extends into the inner side of the mounting frame 2 and abuts against the outer wall of the turntable 9.

[0047] The beneficial effect of adopting the preferred solution in the above embodiment is that when the limit screw 10 is turned, the limit screw 10 abuts against the outer wall of the turntable 9 to prevent rotation, thereby achieving fixation.

[0048] Specifically, according to the contour appearance of the casting to be polished, the rotation angle of the turntable 9 is first adjusted to determine the direction of the length direction of the chute 3 and then fixed.

[0049] Preferably, a crank 11 is fixedly connected to the end surface of the turntable 9 on the side away from each other.

[0050] The beneficial effect of adopting the preferred solution in the above embodiment is that the crank 11 makes it convenient for the staff to grasp and shake the turntable 9.

[0051] Example 4

[0052] like Figures 2 to 3 As shown, preferably, on the basis of embodiments 1-3, a plurality of first telescopic rods 12 and a plurality of second telescopic rods 13 are respectively fixed to the two ends of the slide 5 in the length direction, the telescopic end of the first telescopic rod 12 points to the top surface of the platform 1 and is fixed to a first bracket 14, the grinding roller 6 is rotatably mounted on the first bracket 14, and a first rotary power source 15 is further mounted on the first bracket 14, and the output shaft of the first rotary power source 15 is dynamically connected to the grinding roller 6 for driving the grinding roller 6 to rotate;

[0053] The telescopic end of the second telescopic rod 13 points to the top surface of the platform 1 and is fixedly connected to a second bracket 16 . The conforming roller 7 is rotatably mounted on the second bracket 16 .

[0054] The beneficial effect of adopting the preferred solution in the above embodiment is: the height of the grinding roller 6 is adjusted by the first telescopic rod 12, and the height of the following roller 7 is adjusted by the second telescopic rod 13 to adapt to different casting contours.

[0055] Specifically, the first telescopic rods 12 and the second telescopic rods 13 are both even in number and are respectively arranged above the first bracket 14 and the second bracket 16 to facilitate fixing the first bracket 14 and the second bracket 16 and balancing the forces;

[0056] The first telescopic rod 12 and the second telescopic rod 13 both include an outer cylinder, which is fixed to the side wall of the slide 5 in the length direction. A sliding column is slidingly arranged in the outer cylinder, one end of the sliding column extends out of the outer cylinder and is fixed to the first bracket 14 and the second bracket 16. The sliding column can be telescopically adjusted. A fixing screw is also installed on the outer wall of the outer cylinder, one end of the fixing screw extends to the inner side of the outer cylinder and abuts against the outer peripheral wall of the sliding column. By tightening the fixing screw, the fixing screw abuts against the outer peripheral wall of the sliding column to prevent the sliding column from sliding.

[0057] As a parallel technical solution of this embodiment, the first telescopic rod 12 and the second telescopic rod 13 may also be electric telescopic rods.

[0058] Example 5

[0059] like Figure 2 As shown, preferably, on the basis of embodiments 1-4, a slide rail groove 17 is opened in the slide rail seat 4, the slide 5 is slidably located in the slide rail groove 17, a threaded rod 18 is rotatably installed in the slide rail groove 17, and the slide 5 is sleeved on the threaded rod 18 and threadedly connected to the threaded rod 18;

[0060] A second rotational power source 19 is further installed in the slide rail groove 17 , and an output shaft of the second rotational power source 19 is power-connected to the threaded rod 18 for driving the threaded rod 18 to rotate.

[0061] The beneficial effects of adopting the preferred solution in the above embodiment are: the threaded rod 18 drives the slide 5 to reciprocate, the movement distance is accurately controlled, and because the thread angle has self-locking properties, the slide 5 will not move due to external forces.

[0062] Example 6

[0063] like Figure 1 As shown, preferably, based on embodiments 1-5, the clamping assembly 8 is a vise.

[0064] The beneficial effects of adopting the preferred solution in the above embodiment are: the vise has a simple structure, is not easily damaged, and is easy to use.
