A connecting part 153 is fixed on the left side of the receiving frame 15, and a baffle is fixed on the connecting part 153. A rotating plate 151 is rotatably connected to the connecting part 153. The rotating plate 151 and the baffle on the connecting part 153 are squeezed and matched. Two torsion springs 152 are fixedly connected between the rotating plate 151 and the connecting part 153, and an extrusion mechanism capable of squeezing the rotating plate 151 is provided on the transfer frame 1.

[0037] See also Figure 3 and Figure 5The extrusion mechanism includes two sliding members 17, which are respectively slidably connected to the front and rear sides of the left side of the transfer frame 1, and a compression spring 19 is fixedly connected between the sliding member 17 and the transfer frame 1. A lifting member 18 is fixedly connected between the sliding members 17, and the rotating plate 151 and the lifting member 18 are both extruded and matched.

[0038] See also Figure 3 , and also includes four extrusion frames 16, which are respectively fixed on the left sides of different fixing members 13, and the left parts of the extrusion frames 16 are all provided with inclined surfaces, and the inclined surfaces on the extrusion frames 16 are extrusion-matched with the corresponding sliding members 17.

[0039] When people need to transfer the camshaft, they can use this equipment to operate it. First, people push the transfer frame 1 to the previous processing point of the camshaft, and then start the first multi-section electric push rod 12. The telescopic ends of the first multi-section electric push rod 12 are all retracted downward by a small section, and the first multi-section electric push rod 12 drives the lower fixing parts 13 to move downward, and the lower fixing parts 13 drive the lower first connecting frame 14 to move downward, and the lower first connecting frame 14 drives the lower receiving frame 15 to move downward, and the lower receiving frame 15 drives the connecting member 153 and then drives the lower rotating plate 151 to move downward, and the lower rotating plate 151 is squeezed and matched with the lifting member 18. At the same time, because a baffle is provided on the lower connecting member 153, the lower rotating plate 151 will not The camshaft 15 is then moved to the left of the support frame 15, and the camshaft 15 is moved to the right of the support frame 15. At the same time, the camshaft 15 is moved to the right of the support frame 15, and the camshaft 15 is moved to the right of the support frame 15. People are then required to manually arrange the camshafts in order. When the receiving frame 15 below is full of camshafts, people start the first multi-section electric push rod 12 again. The telescopic ends of the first multi-section electric push rod 12 are all retracted downward, and the telescopic ends of the first multi-section electric push rod 12 drive the extrusion frames 16 to move downward, so that the extrusion frames 16 below are all in contact with and squeezed by the sliding members 17, so that the sliding members 17 drive the lifting members 18 to move left, and the compression springs 19 are all compressed. The lifting members 18 no longer block the rotating plate 151, so that the receiving frame 15 below is restored to a horizontal state, so that the first connecting frame 14 below can drive the receiving frame 15 below to move downward. When the extrusion frames 16 below are all disengaged from the sliding members 17, the compression springs 19 are reset to drive the sliding members 17 to move left. The parts 17 all move to the right to reset, the sliding parts 17 all drive the lifting parts 18 to move to the right to reset, the lower first connecting frame 14 drives the connecting rod 141 to move downward, and then drives the upper first connecting frame 14 to move downward, the upper first connecting frame 14 drives the upper receiving frame 15 to move downward, the upper receiving frame 15 drives the upper rotating plate 151 to move downward, so that the upper rotating plate 151 and the lifting parts 18 are pressed and matched, so that the upper receiving frame 15 rotates clockwise, and the upper receiving frame 15 rotates from a horizontal state to a state tilted downward from left to right, and then people close the first multi-section electric push rods 12, and then people can place the camshaft on the upper receiving frame 15, and people put the camshaft on the left part of the upper receiving frame 15,Then the camshaft will roll to the right part of the upper receiving frame 15. When the upper receiving frame 15 is full of camshafts, people control the telescopic ends of the first multi-section electric push rod 12 to extend upward for a distance, so that the upper receiving frame 15 is no longer squeezed by the lifting member 18, so that the upper receiving frame 15 rotates counterclockwise to return to a horizontal state, and then people can push the transfer frame 1 to the next processing point of the camshaft. After arriving at the destination, people control the telescopic ends of the first multi-section electric push rod 12 to retract downward for a distance, so that the upper receiving frame 15 is squeezed by the lifting member 18, and then The upper receiving frame 15 rotates clockwise to an inclined state, and then the camshaft can roll down from the right part of the upper receiving frame 15, so that people no longer need to unload manually. When the camshafts on the upper receiving frame 15 are removed, people control the telescopic ends of the first multi-section electric push rods 12 to extend, so that the lower receiving frame 15 moves upward, and the lower receiving frame 15 drives the lower connecting piece 153 and then drives the lower rotating plate 151 to move upward. When the upper side of the lower rotating plate 151 is squeezed with the lifting piece 18, the lower rotating plate 151 will be squeezed and flipped downward, and the lower The torsion springs 152 are all twisted, and the sliding members 17 are squeezed and matched with the extrusion frame 16, so that the sliding members 17 drive the lifting members 18 to be squeezed and moved to the left, and the compression springs 19 are all compressed. When the extrusion frame 16 moves upward to disengage from the sliding member 17, the compression springs 19 are reset to drive the sliding member 17 and then drive the lifting member 18 to move rightward and reset. When the rotating plate 151 below is separated from the lifting member 18, the torsion springs 152 below are reset to drive the rotating plate 151 below to flip upward and reset. Then people control the telescopic ends of the first multi-section electric push rod 12 to retract downward. The camshaft on the lower receiving frame 15 is removed, so that the camshaft is transported. The above operation squeezes the rotating plate 151 through the lifting member 18, so that the receiving frame 15 rotates clockwise to a state of tilting downward from left to right. Then people only need to put the camshaft on the left part of the receiving frame 15, and the camshafts can automatically roll to the right one by one, so that people can put the camshaft on the receiving frame 15 conveniently, and no longer need to manually put it on the transfer frame 1 and arrange it neatly, which is more convenient, time-saving and labor-saving.

[0040] Example 2: Based on Example 1, please refer to Figure 8-Figure 10 , and also includes a blocking mechanism that can prevent the camshafts placed on the receiving frame 15 from colliding with each other and causing damage. The blocking mechanism includes two first buffer members 2, and the first buffer members 2 are respectively clamped on the right part of different first connecting frames 14. Fourteen rollers 24 are symmetrically rotatably connected to the receiving frame 15, and seven trigger members 21 are slidably connected to each receiving frame 15. Seven second buffer members 22 are slidably connected to the receiving frame 15.

[0041] See also Figure 8-Figure 10 , and also includes twenty-eight pull ropes 23, one end of each two pull ropes 23 are symmetrically fixed on the front and rear sides of the upper side of the same second buffer member 22, and the other ends of the pull ropes 23 are passed around the corresponding rollers 24, and then pass through the gap between the first connecting frame 14 and the receiving frame 15, and finally fixed on the front and rear sides of the lower side of the trigger member 21.

[0042] When the camshafts roll on the receiving frame 15, the camshafts will collide with each other, which will affect the accuracy of the camshafts. Therefore, a blocking mechanism is provided to separate the camshafts. The working principle is as follows: when people put the camshafts on the receiving frame 15, because the receiving frame 15 is in an inclined state at this time, the camshafts will roll toward the right part of the receiving frame 15. After the first camshaft is put on, the first camshaft will roll to the right part of the receiving frame 15 and will be blocked by the first buffer 2, thereby preventing the camshaft from rolling out. People no longer need to manually block the camshaft. At the same time, because the first buffer 2 buffers the camshaft, it can prevent the camshaft from colliding. When each camshaft stops, due to the camshaft's own gravity, the camshaft drives the corresponding trigger member 21 to move downward, and the trigger member 21 pulls the corresponding pull rope 23 downward, so that the pull rope 23 pulls the corresponding second buffer member 22 upward, so that the second buffer member 22 moves upward and blocks the next camshaft. The buffering effect of the punch 22 on the camshaft can separate the camshafts, thereby preventing the camshafts from colliding with each other during the rolling and transportation of the camshafts. When the camshafts need to be unloaded, the receiving frame 15 is also in a tilted state. Then people only need to pull out the first buffer 2 so that the rightmost camshaft is not blocked and the rightmost camshaft rolls down. Then, after the rightmost camshaft rolls out, the rightmost trigger member 21 is no longer squeezed downward, and the rightmost second buffer 22 is no longer pulled by the pull rope 23. The rightmost second buffer 22 drops due to its own gravity, so that the second buffer 22 no longer blocks the camshaft, so that the camshafts can be rolled out and unloaded one by one. The above operation can prevent the rightmost camshaft from rolling out by setting the first buffer 2, and people no longer need to manually block it. By setting the second buffer 22, the camshafts can be separated from each other, thereby preventing the camshafts from colliding with each other during the rolling and transportation of the camshafts.

[0043] See also Figure 11-Figure 12, and also includes a centering mechanism that can limit the camshaft during the rolling process of the camshaft to prevent the camshaft from deviating and causing the storage or retrieval to be unable to be completed. The centering mechanism includes two second multi-section electric push rods 3, one of which is fixed to the fixing piece 13 on the front side below, and the other is fixed to the fixing piece 13 on the rear side below. A lower pressure frame 31 is fixed to the telescopic end of the second multi-section electric push rod 3, fourteen centering pieces 35 are symmetrically slidably connected to the first connecting frame 14, and a pushing frame 33 is slidably connected to the centering piece 35, and two pushing springs 34 are fixed between the centering piece 35 and the pushing frame 33.

[0044] See also Fig.11 , and also includes twenty-eight limiting members 32, which are symmetrically fixed on the two lower pressure frames 31, and the limiting members 32 are all inclined, and the pushing frames 33 are slidably connected to the corresponding limiting members 32.

[0045] Because there are differences between camshafts of different specifications, the camshaft may be offset when rolling on the receiving frame 15, which may cause the camshaft to get stuck when being stored or taken out. Therefore, a centering mechanism that can roll the camshaft in the center is provided. The following is its working principle: when people load the camshaft, they control the telescopic ends of the second multi-section electric push rod 3 to retract a certain distance, and the telescopic ends of the second multi-section electric push rod 3 drive the lower pressure frame 31 and then drive the limiting members 32 to move downward a certain distance. The limiting members 32 squeeze the corresponding pushing frames 33, so that the pushing frames 33 on the front and rear sides move toward the side close to each other, and the pushing frames 33 drive the pushing springs 34 and then drive the centering members 35 to move toward the side close to each other. Under the action of the centering member 35, the camshaft can be clamped and The camshaft is centered by the push spring 34, and the centering piece 35 is prevented from excessively clamping the camshaft, thereby preventing the camshaft from rolling. When the camshaft is completely removed, people control the telescopic ends of the second multi-section electric push rod 3 to extend, and the second multi-section electric push rod 3 drives the lower pressure frame 31 and then drives the limiting member 32 to move upward, so that the limiting member 32 drives the pushing frame 33 to move toward the side away from each other, and the pushing frame 33 drives the pushing spring 34 and then drives the centering piece 35 to move toward the side away from each other and reset. The above operation squeezes the pushing frame 33 through the limiting member 32, so that the pushing frame 33 drives the pushing spring 34 and then drives the centering piece 35 to move toward the side close to each other, so that the centering piece 35 clamps the camshaft in the center, thereby preventing the camshaft from deviating when rolling, resulting in jamming.

[0046] See also Figure 13-14, and also includes a covering mechanism that can prevent impurities in the air from contaminating the camshaft during storage, the covering mechanism includes a second connecting frame 4, the second connecting frame 4 is fixed between the upper parts of the connecting rods 141, a cloth cover 46 is fixed to the lower side of the second connecting frame 4, two pressure springs 45 are fixedly connected between the second connecting frame 4 and the cloth cover 46, a guide frame 42 is fixed on both the front and rear sides of the left part of the cloth cover 46, a limiting frame 43 is slidably connected to the guide frame 42, a force storage spring 44 is fixedly connected between the guide frame 42 and the limiting frame 43, and the limiting frame 43 and the second connecting frame 4 are snap-fitted.

[0047] See also Figure 13-14 , and also includes two extrusion pieces 41, which are symmetrically fixed on the left part of the transfer frame 1, and the lower part of the limiting frame 43 is extruded and matched with the corresponding extrusion pieces 41.

[0048] Because there are impurities in the air, in order to prevent the camshaft from being contaminated with too much impurities in the air, a covering mechanism that can cover all the camshafts is provided. The following is its working principle: during the loading process of the camshaft, the first multi-section electric push rod 12 will drive the fixing piece 13 and then drive the first connecting frame 14 to move downward, the first connecting frame 14 drives the connecting rod 141 to move downward, and the connecting rod 141 drives the second connecting frame 4 to move downward, so that the second connecting frame 4 drives the cloth cover 46 and then drives the guide frame 42 to move downward, and the guide frame 42 drives the limiting frame 43 to move downward. When all the camshafts are installed, the telescopic ends of the first multi-section electric push rod 12 continue to move downward a short distance, so that the limiting frames 43 are in contact with and squeezed with the corresponding extrusion members 41, so that the limiting frames 43 are squeezed and move toward the side away from each other, the storage springs 44 are stretched, and the limiting frames 43 are separated from the second connecting frame 4. When the extrusion members 41 and the limiting frames 43 are separated, the storage springs 44 are The pressure springs 45 are reset, and the pressure springs 45 are reset to drive the cloth covers 46 to expand downward, so that the cloth covers 46 cover all the camshafts, thereby preventing the camshafts from being contaminated by impurities in the air during storage and transportation. When people need to remove the camshafts, they manually retract the cloth covers 46 upwards and re-engage the limiting frames 43 with the second connecting frame 4, and the pressure springs 45 are compressed again. The above operation is squeezed and matched by the limiting frames 43 and the extrusion pieces 41, so that the limiting frames 43 move toward the sides away from each other, and the limiting frames 43 are disengaged from the second connecting frame 4, so that the pressure springs 45 are reset from the compressed state, and the pressure springs 45 drive the cloth covers 46 to expand downward, so that the cloth covers 46 cover all the camshafts, thereby preventing the camshafts from being contaminated by impurities in the air during storage and transportation.
