Description

Technical Field

[0001] This utility model relates to the technical field of metal casting processing, specifically a grinding device for the gate of metal casting. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods, including cast steel, cast iron, cast copper, and cast aluminum. Castings are objects with certain shapes, sizes, and properties obtained by pouring, injecting, sucking, or other casting methods into a pre-prepared mold after smelting molten metal and cooling it.

[0003] For example, the casting gate grinding device with authorization announcement number "CN220463273U" solves the problem that existing casting gate grinding devices still require manual removal after processing, affecting the processing efficiency of castings. The above-mentioned device uses two sets of placement components, one for grinding and the other for placing the pre-casting. With the rotation of the rotating plate, after the upper placement component is processed, the positions of the two placement components are reversed and replaced, which improves processing efficiency and facilitates the feeding and removal of castings. Considering that existing casting gate grinding devices require pulling out the pull frame for internal cleaning when grinding the casting gate, and cannot directly discharge it to the outside, the cleaning is relatively troublesome. Utility Model Content

[0006] Preferably, the fixing mechanism includes a first mounting base, the inner wall of the first mounting base is fixedly connected to the base frame by bolts, the outer wall of the first mounting base is fixedly connected to a second electric telescopic rod, the output end of the second electric telescopic rod is fixedly connected to the placement box, and the inner wall of the placement box is threadedly connected to a threaded rod.

[0007] Preferably, the outer wall of the left end of the base frame is fixedly connected to the second mounting base by bolts, and the upper end of the base frame is connected to a collection mechanism.

[0008] Preferably, the collection mechanism includes a collection box, the outer wall of which is movably connected to the base frame, and the inner wall of which is machined with a groove, the inner wall of which is fixedly connected to the discharge pipe.

[0010] Preferably, the inner wall of the protective box is equipped with a spray nozzle.

[0011] The present invention proposes a grinding device for metal casting gates, which has the following advantages: the grinding disc is rotated by a servo motor to grind the gate of the metal casting; the nozzle on the protective box can intercept debris and cool the surface temperature; water and metal debris are blocked by the protective box and fall into the collection box; guided by the slope inside the collection box, they move into the groove and are finally discharged outward from the discharge pipe; the metal debris can be discharged directly outward, making cleaning simpler.

[0020] Example 1:

[0021] Please see Figure 1-6 In this embodiment, a grinding device for the gate of a metal casting includes a base frame 1 and a horizontal plate 2. The upper end of the base frame 1 is fixedly connected to the horizontal plate 2 by bolts. The inner wall of the horizontal plate 2 is slidably connected to a slide block 3. The lower end of the slide block 3 is fixedly connected to a first electric telescopic rod 4. The model of the first electric telescopic rod 4 is determined according to actual needs and can meet the working requirements. The output end of the first electric telescopic rod 4 is fixedly connected to a protective box 5. A fixing mechanism 6 is connected to the outer wall of the right end of the base frame 1.

[0022] The fixing mechanism 6 includes a first mounting base 601. By turning the threaded rods 604 in different directions, the upper placement box 603 can be rotated, so that the metal casting can be fixed to the placement box 603. The inner wall of the first mounting base 601 is fixedly connected to the base frame 1 by bolts. The outer wall of the first mounting base 601 is fixedly connected to the second electric telescopic rod 602. The model of the second electric telescopic rod 602 is determined according to actual needs and can meet the working requirements. The output end of the second electric telescopic rod 602 is fixedly connected to the placement box 603. The inner wall of the placement box 603 is threadedly connected to the threaded rod 604.

[0023] The outer wall of the left end of the base frame 1 is fixedly connected to the second mounting seat 7 by bolts. The upper end of the base frame 1 is connected to the collection mechanism 8. Water and metal debris are blocked by the protective box 5 and fall into the collection box 801. The slope inside the collection box 801 guides the material to move into the groove 802 for centralized collection. The collection mechanism 8 includes the collection box 801. The outer wall of the collection box 801 is movably connected to the base frame 1. The inner wall of the collection box 801 is machined with a groove 802. The inner wall of the groove 802 is fixedly connected to the discharge pipe 803. The outer wall of the first mounting seat 601 is equipped with a servo motor 9. The model of the servo motor 9 is determined according to actual needs and only needs to meet the working requirements. The output shaft of the servo motor 9 is fixedly connected to the grinding disc 10. The inner wall of the protective box 5 is equipped with a nozzle 11.

[0024] Servo motor 9 drives grinding disc 10 to grind the gate of metal casting. Spray nozzle 11 on protective box 5 can intercept debris and cool the surface temperature. Water and metal debris are blocked by protective box 5 and fall into the collection box 801. Guided by the slope inside collection box 801, they move into groove 802 and are finally discharged outward from discharge pipe 803. Metal debris can be discharged directly outward, making cleaning simpler.

[0025] Working principle:

[0026] By inserting the metal casting with its port facing outward into the placement box 603, and manually turning the threaded rods 604 in different directions to rotate the upper placement box 603, the height at which the metal casting is fixed to the placement box 603 can be controlled, and the end of the threaded rod 604 can be pressed against the outer wall of the metal casting, thus fixing the metal casting to the placement box 603. At the same time, the slide block 3 is pushed on the horizontal plate 2 to move to the upper end of the grinding disc 10, the external power supply of the first electric telescopic rod 4 is turned on, and the first electric telescopic rod 4 starts to work. The first electric telescopic rod 4 pushes the protective box 5 downward until the lower end of the protective box 5 contacts the surface of the collection box 801, and the second electric telescopic rod 4 is turned on. The telescopic rod 602 is connected to an external power source. The second electric telescopic rod 602 begins operation, pushing the placement box 603 closer to the grinding disc 10. Then, the external power source for the servo motor 9 is connected, and the servo motor 9 begins operation. The servo motor 9 drives the grinding disc 10 to rotate and grind the gate of the metal casting. Meanwhile, the nozzle 11 on the protective box 5 intercepts debris and cools the surface temperature. Water and metal debris are blocked by the protective box 5 and fall into the collection box 801. Guided by the slope inside the collection box 801, they move into the groove 802 and are finally discharged outwards through the discharge pipe 803, achieving the effect of grinding the gate of the metal casting. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
