[0025] The portable precision casting cutting machine of the utility model is described in more detail below with reference to the accompanying drawings and through specific implementation methods.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0027] See also Figure 1-Figure 4 The portable precision casting cutting machine of this embodiment can unfold and fold the cutting machine, which is convenient for transferring and carrying the cutting machine, so that the cutting machine can be moved to a suitable position to cut precision castings to meet different cutting needs. At the same time, the replacement and cutting speeds of castings are relatively fast, which can speed up the overall cutting efficiency. In this embodiment, it mainly includes a base 1, and both ends of the base 1 are fixedly provided with a fixing plate 6, and the fixing plate 6 is provided with a through hole 7 for inserting bolts to fix the cutting machine. The cutting machine is fixed to a suitable cutting position such as a desktop or countertop by the fixing plate 6, which is convenient for subsequent cutting operations.

[0028] For fixing castings of different sizes and shapes. Figure 1-Figure 3 In this embodiment, the end of the base 1 is provided with a clamping unit 2 that can be turned outward, and the casting is fixed by the clamping unit 2. The clamping unit 2 includes a support plate 211 hingedly provided at both ends of the base 1, and a protrusion 212 is provided on the outer side of the end of the support plate 211 away from the base 1, and the fixing plate 6 with the through hole 7 is also provided on the side of the protrusion 212. When the support plate 211 is unfolded and flattened, the protrusion 212 contacts the table top or table top, and the fixing plate 6 is fixed to the table top or table top by inserting a bolt into the through hole 7. At this time, the top end of the support plate 211 is in a horizontal state with the top surface of the base 1.

[0029] The inner side of the support plate 211 is provided with a movable plate 213 that can slide along its length direction, and the rear side of the movable plate 213 is fixedly provided with a rack 214. The rear side of the support plate 211 is rotatably provided with a gear 215 that drives the rack 214 to move, and the outer side of the support plate 211 is rotatably provided with a torsion bar 216 that drives the gear 215 to rotate. The torsion bar 216 is tightly connected with the support plate 211, and the resistance is large when rotating. The tooth block is rotated by rotating the torsion bar 216, so that the rack 214 is driven to drive the movable plate 213 to slide on the support plate 211. The inner side of the movable plate 213 is provided with a clamping frame 218 that can move along the length direction of the support plate 211 through a first lead screw 217 that is rotatably provided with the first lead screw 217. The support frame is slid on the movable plate 213 by rotating the first lead screw 217, so that the length that can be clamped can be adjusted in coordination with the movable plate 213 to adapt to castings to be cut of different lengths.

[0030] The inner bottom of the clamping frame 218 is fixedly provided with a first clamping plate 219, and the inner side of the clamping frame 218 is provided with a second clamping plate 221 which can move relative to the first clamping plate 219 through a second screw 220 which is rotatably arranged therewith. The torsion bar 216 is also arranged at the ends of the first screw 217 and the second screw 220. By rotating the torsion bar 216 to rotate the second screw 220, the relative position of the first clamping plate 219 and the second clamping plate 221 is changed, thereby changing the thickness of the casting that can be clamped, and then adapting to castings of different thicknesses to be cut. And the position of the corresponding moving frame 31 and the support frame can be adjusted to change the position of the precision casting cutting. When the cutting machine is transferred, the support plate 211 can be flipped over the base 1, and the moving plate 213 and the support frame can be controlled to move toward the base 1, so as to realize the folding of the cutting machine and facilitate the subsequent transfer.

[0031] In order to facilitate the separation of the castings. In this embodiment, see Figure 1-Figure 4 , a moving unit 3 that can move relative to the base 1 is provided on the side of the base 1. The moving unit 3 includes a moving frame 31 that slides relative to the base 1, and the base 1 is fixedly provided with at least one connecting rod 32 that penetrates the moving frame 31 relative to the side of the moving frame 31, and the connecting rod 32 plays a guiding role to ensure the relative sliding of the moving frame 31 and the base 1. A support plate 33 that supports the bottom end of the moving frame 31 is fixedly provided at the bottom end of the base 1. The support plate 33 reduces the friction resistance of the moving frame 31 when it moves, which facilitates subsequent cutting. A protective plate 34 that is set on the base 1 is fixedly provided at the top of the moving frame 31, which can protect the desktop or countertop during cutting to prevent the high-temperature residue cut off from falling on the desktop or countertop and causing damage to it. A handle 35 is fixedly provided at the end of the moving frame 31 opposite to the base 1, which is convenient for carrying and moving.

[0032] The mobile unit 3 is provided with a separation unit 4 for cutting the casting. The base 1, the clamping unit 2 and the mobile unit 3 cooperate to form a foldable structure. When not in use, the clamping unit 2 and the mobile unit 3 can be retracted to the position of the base 1, so as to facilitate subsequent movement. The separation unit 4 includes a mounting frame 41 fixedly arranged in the middle of the top of the mobile frame 31, and an operating panel 42 is hingedly arranged at the top of the mounting frame 41, and a cutter 43 driven by a motor 44 is fixedly arranged on the operating panel 42. The cutter 43 driven by the motor 44 is a mature prior art and is not described here. An operating rod 45 for controlling the swing of the operating panel 42 along the hinge point between the operating panel 42 and the mounting frame 41 is fixedly arranged on the side of the operating panel 42. The operating rod 45 is used to swing the cutter 43 up and down around the hinge point between the operating panel 42 and the mounting frame 41, so as to facilitate the cutting of precision castings, and at the same time, the cutter 43 can be attached to the mobile frame 31 when not in use. The top of the protection plate 34 is fixedly provided with a stopper 46 for limiting the lowest position of the operating plate 42. The stopper 46 limits the lowest position that the cutter 43 can reach, so as to avoid the cutting blade on the cutter 43 abutting against the movable frame 31 and causing damage to both.

[0033] In order to facilitate the folding and transfer of the cutting machine. Figure 1-Figure 3 , the movable unit 3 is provided with a frame 5 which can limit the clamping unit 2. Vertical plates 8 are fixedly provided at both ends of the movable frame 31, and the frame 5 is hingedly provided on the vertical plates 8. A limiting rod 9 which can limit the cutter 43 is provided in the middle of the frame 5. When the cutting machine moves, the position of the clamping unit 2 is limited by flipping the frame 5 and putting it behind the clamping unit 2 which has been folded on the base 1, and at the same time, the position of the cutter 43 is limited by the limiting rod 9. A limiting hole 10 corresponding to the position of the protrusion 212 is provided on one side of the end of the frame 5, and a deep groove corresponding to the limiting hole 10 and cooperating with the bolt is provided on the protrusion 212, and the frame 5 is limited by inserting the bolt into the limiting hole 10 and abutting against the protrusion 212. The frame 5 and the protrusion 212 are fixed by bolts and the limiting holes 10, so as to limit the position of the cutting machine when it is folded, ensure that the cutting machine will not unfold when it is carried or transferred, and facilitate the transfer of the cutting machine.

[0034] The method of using the portable precision casting cutting machine of the utility model is as follows: first, when there is no need to change the position and cut the casting, the support plate 211 is flipped to the top of the base 1, and the movable plate 213 and the support frame are controlled to move toward the base 1, so as to realize the folding of the cutting machine, the clamping unit 2 and the movable unit 3 are retracted toward the position of the base 1, and the frame 5 is flipped and sleeved behind the clamping unit 2 that has been folded on the base 1, so as to limit the position of the clamping unit 2, and at the same time, the position of the cutter 43 is limited by the limiting rod 9. The frame 5 is fixed to the protrusion 212 by bolts and limiting holes 10, so as to realize the limit of the cutting machine when folding, and ensure that the cutting machine will not unfold when being carried or transferred. At this time, the lowest position that the cutter 43 can reach is limited by the blocking block 46 to prevent the cutting blade on the cutter 43 from abutting against the movable frame 31 and causing damage to both.

[0035] When cutting is required, the cutter is moved to a suitable position such as a table or countertop by the handle 35. The cutter is fixed by inserting bolts into the fixing plate 6. Then, the limit of the frame 5 is cut off and it is flipped to the rear of the cutter 43. The support plate 211 is flipped from the base 1 to both ends until it is unfolded and flattened. At this time, the protrusion 212 contacts the countertop or tabletop, and the fixing plate 6 is fixed to the tabletop or countertop by inserting bolts into the through hole 7. The top of the support plate 211 is in a horizontal state with the top surface of the base 1.

[0036] The gear 215 is driven to rotate by rotating the torsion bar 216, thereby driving the mobile plate 213 to slide on the support plate 211 by driving the rack 214. Then, the first screw 217 is rotated by the torsion bar 216 to make the support frame slide on the mobile plate 213, so that it can cooperate with the mobile plate 213 to adjust the length that can be clamped, so as to adapt to castings to be cut of different lengths. And by rotating the torsion bar 216, the second screw 220 is rotated to change the relative position of the first clamping plate 219 and the second clamping plate 221, so as to change the thickness of the casting that can be clamped, and then adapt to castings to be cut of different thicknesses. Therefore, the position of the corresponding mobile frame 31 and the support frame can be adjusted according to the size and shape of the precision casting and the position to be cut, so as to change the position of the precision casting cutting. Before this, the mobile frame 31 is moved away from the base 1 through the connecting rod 32 to facilitate the addition and fixing of the casting.

[0037] Then the cutter 43 is driven by the motor 44 to work, and the mobile frame 31 can be moved toward the base 1. In this process, the connecting rod 32 plays a guiding role, and the mobile frame 31 can move on the support plate 33, reducing the friction resistance when the mobile frame 31 moves, which is convenient for subsequent cutting. Then, according to the actual situation, the cutter 43 can be swung up and down around the hinge point between the operating plate 42 and the mounting frame 41 through the operating rod 45 to cut the precision casting. In this process, the desktop or table top is protected by the protective plate 34 to prevent the cut high-temperature slag from falling on the desktop or table top and causing damage to it.
