[0025] The utility model will be further described below in combination with the drawings and examples:
[0026] Example one: can see Figures 1-9 A mower disc welding tool, which comprises a base 1, a profiling block 2, a positioning disc 3, a first pressing mechanism 4, a second pressing mechanism 5, a jacking rod 6 and a limiting stop piece 7.
[0027] Among them, the profiling block 2 is arranged on the base 1 and is used to support the outer wall surface of the mower disc main body N-1.In this embodiment, the profiling block 2 has four and is used to support the outer wall surface four corners of the mower disc main body N-1.
[0028] Specifically, the four profiling blocks 2 are rectangularly distributed; the upper surface of each profiling block 2 is matched with the shape of the contact part of the mower disc main body N-1.
[0029] Among them, the positioning disc 3 is fixedly arranged on the base 1 and is used to cooperate with the center hole N-11 of the mower disc main body N-1.
[0030] Among them, the limiting stop piece 7 is rotatably arranged on the base 1 and is used to limit the side end of the fender N-2; specifically, the base 1 is fixedly provided with a support 8, the limiting stop piece 7 is L-shaped, and one end of the limiting stop piece 7 is hinged to the upper end of the support 8. Figures 6-9During clamping, the limiting stop 7 rotates on the support 8 until it contacts the inner wall of the mowing disc body N-1. Then, one end of the grass-blocking plate contacts the limiting stop 7 and is blocked and limited. After the second end of the grass-blocking plate N-2 is welded to the contact point with the inner wall of the mowing disc body N-1, the limiting stop 7 is rotated again. The limiting stop 7 tilts upward and moves away from the contact point between the first end of the grass-blocking plate and the inner wall of the mowing disc body N-1. Then, welding can be performed on the first end of the grass-blocking plate that contacts the inner wall of the mowing disc body N-1. At this time, because the limiting stop 7 rotates to avoid the welding torch, there will be no welding interference problem.
[0031] The top rod 6 is rotatably mounted on the positioning plate 3 at one end, and the other end of the top rod 6 is used to press against the grass-blocking plate N-2. Specifically, a rotating seat 3-1 is fixedly mounted on the positioning plate 3, and one end of the top rod 6 is rotatably engaged with the rotating seat 3-1. (See also...) Figures 6-9 During clamping, one end of the push rod 6 rotates on the locating plate 3 rotating seat 3-1. When the push rod 6 is in a horizontal state, the other end of the push rod 6 normally presses against the grass baffle N-2, ensuring that both ends of the grass baffle N-2 are in contact and pressed against the inner wall of the mowing disc body N-1. After welding is completed, the push rod 6 can be rotated to loosen the pressing of the other end of the push rod 6, and at the same time, the push rod 6 is in a vertical state so that it can pass through the central hole N-11 of the mowing disc body N-1 when the workpiece is removed after welding.
[0032] The first pressing mechanism 4 and the second pressing mechanism 4 are respectively arranged on both sides of the base 1 and are used to press the mowing disc body N-1.
[0033] Specifically, the first pressing mechanism 4 includes a first support 4-1, a first pressing frame 4-2, and a first driving cylinder 4-3; the first support 4-1 is fixedly mounted on the base 1, the middle part of the first pressing frame 4-2 is hinged to the upper end of the first support 4-1; the rear end of the first pressing frame 4-2 is hinged to the output end of the first driving cylinder 4-3, the bottom of the first driving cylinder 4-3 is hinged to the base 1, and the front end of the first pressing frame 4-2 is provided with a first contouring pressing block 4-4. (See also...) Figures 6-9 During clamping, the first drive cylinder 4-3 operates and drives the rear end of the first pressing frame 4-2 to move upward, causing the middle part of the first pressing frame 4-2 to rotate clockwise at the upper end of the first support 4-1. The front end of the first pressing frame 4-2 presses downward and rotates, causing the first contouring pressing block 4-4 to press against the inner edge of the mowing disc body N-1. After welding is completed, the first drive cylinder 4-3 is activated and drives the front end of the first pressing frame 4-2 to move upward, causing the middle part of the first pressing frame 4-2 to rotate counterclockwise at the upper end of the first support 4-1. The front end of the first pressing frame 4-2 releases downward and upward, moving away from the first contouring pressing block 4-4 and pressing against the inner edge of the inner wall of the mowing disc body N-1, without interference when the workpiece is removed.
[0034] Specifically, the second pressing mechanism 3 includes a second support 5-1, a second pressing frame 5-2, and a second drive cylinder 5-3; the second support 5-1 is fixedly mounted on the base 1, and the middle part of the second pressing frame 5-2 is hinged to the upper end of the second support 5-1; the rear end of the second pressing frame 5-2 is hinged to the output end of the second drive cylinder 5-3, the bottom of the second drive cylinder 5-3 is hinged to the base 1, and the front end of the second pressing frame 5-2 is provided with a second contouring pressing block 5-4. (See also...) Figures 6-9 During clamping, the second drive cylinder 5-3 operates and drives the rear end of the second pressing frame 5-2 to move upward, causing the middle part of the second pressing frame 5-2 to rotate clockwise at the upper end of the second support 5-1. The front end of the second pressing frame 5-2 presses downward and rotates, causing the second contouring pressing block 5-4 to press against the inner edge of the other side of the mowing disc body N-1. After welding is completed, the second drive cylinder 5-3 is activated and drives the front end of the second pressing frame 5-2 to move upward, causing the middle part of the second pressing frame 5-2 to rotate counterclockwise at the upper end of the second support 5-1. The front end of the second pressing frame 5-2 releases downward and upward, moving away from the second contouring pressing block 5-4 and pressing against the inner edge of the other side of the mowing disc body N-1, without interference when the workpiece is removed.
[0035] Before clamping, a comparison can be made. Figure 4 and Figure 5 First, the first pressing frame 4-2 of the first pressing mechanism 4, the second pressing frame 5-2 of the second pressing mechanism 3, the top rod 6, and the limit stop 7 must all be rotated to the first working state (which is also the loosened state after welding is completed, combined with...). Figure 5 ), so as to leave space for the main body of the mowing tray N-1 to be installed.
[0036] See also Figures 6-9 The operation process of this embodiment is as follows: During clamping, the mowing disc body N-1 is first placed on the contour block 2 and stably supported. At the same time, the positioning disc 3 is made to cooperate with the center hole N-11 of the mowing disc body N-1. At this time, the mowing disc body N-1 is supported by the reference positioning. Then, the grass baffle N-2 is installed into the mowing disc body N-1 and one side of the grass baffle N-2 contacts the limiting stop 7 for limitation. Then, the top rod 6 is rotated so that the other end of the top rod 6 presses against the grass baffle N-2. Then, the first pressing mechanism 4 and the second pressing mechanism 4 press the two sides of the mowing disc body N-1 respectively. At this time, the positioning and clamping of the mowing disc body N-1 and the grass baffle N-2 are completed. The mowing disc body N-1 and the grass baffle N-2 maintain a precise relative position and are fixedly constrained.
[0037] When the clamping is completed, the manual or welding robot can be started to weld the contact between the second side end of the grass baffle N-2 and the inner wall of the grass cutting disc body N-1, then the limiting stop piece 7 is rotated to avoid the interference of the welding gun, and then the contact between the first side end of the grass baffle N-2 and the inner wall of the grass cutting disc body N-1 is welded, so that the welding of the two side ends of the grass baffle N-2 and the inner wall of the grass cutting disc body N-1 can be realized. Since the limiting stop piece 7 can be rotated to avoid the interference problem.
[0038] The first pressing mechanism 4 and the second pressing mechanism 4 can be combined Figure 5 When the welding is completed, the first pressing mechanism 4 and the second pressing mechanism 4 are first loosened to release the grass cutting disc body N-1, then the top rod 6 is rotated to a vertical state or a vertical state with a small angle, so that the top rod 6 can pass out of the center hole N-11 when the workpiece is taken out, and then the workpiece is taken out from the tooling.
[0039] The first pressing mechanism 4 and the second pressing mechanism 4 can be combined Figures 6-9 In the clamping, the grass cutting disc body N-1 is positioned, supported and stably pressed, the grass baffle N-2 is limited by the limiting stop piece 7 and the top rod 6, the relative position of the grass baffle N-2 and the grass cutting disc body N-1 is accurate and fixed, the welding quality can be guaranteed, and the limiting stop piece 7 can be rotated to limit the first end of the grass baffle N-2 during welding, and after the first end is welded (welded and fixed as a whole, and no longer limited), the limiting stop piece 7 is rotated to avoid interference, and the welding of the second end of the grass baffle N-2 can be avoided, which is very ingenious and meets the production requirements.
[0040] The first pressing mechanism 4 and the second pressing mechanism 4 can be combined Figures 6-9 In addition, during the welding clamping, the top rod 6 is rotated to press the grass baffle N-2, and before the workpiece is taken out after welding, the direction of the top rod 6 is rotated, so that the top rod 6 can pass out of the center hole N-11 when the workpiece is taken out (the first pressing mechanism 4 and the second pressing mechanism 4 can be combined Figure 5 ), which is very ingenious, can guarantee that the grass baffle N-2 is pressed during welding, and the workpiece can be normally taken out after welding, and meets the production requirements.
[0041] The embodiment has the advantages of simple clamping, accurate positioning, stable and reliable, can guarantee the welding quality of the product, can complete normal clamping and workpiece taking out, and can improve the production efficiency.
