DETAILED DESCRIPTION

[0017] The above scheme is further described in combination with specific embodiments. It should be understood that these embodiments are used to illustrate the present application and do not limit the scope of the present application. The implementation conditions used in the embodiments can be further adjusted according to the specific conditions of the manufacturer, and the implementation conditions not marked are usually the conditions in the conventional experiment.

[0018] Example 1, an intelligent casting equipment for compressor accessory production, as shown in Figure 1 ,Figure 2 、 Figure 6 and Figure 7 As shown, it includes a sand box 1 and a cylinder 1 2; two eccentrically arranged cylinders 1 2 are welded on the sand box 1, and the cylinder 1 2 is set to an alloy material; it also includes a square frame 3, a cylinder 2 4, a ring 1 5, a ring 2 6 and a fixing component; all cylinders 1 2 are connected to a square frame 3, and the square frame 3 is located outside the sand box 1; four cylinders 2 4 are welded on the square frame 3; each cylinder 2 4 is connected to a ring 1 5; each ring 1 5 is welded to a ring 2 6; the square frame 3 is connected to a fixing component.

[0019] The fixing assembly includes an electric push rod 201 and a round rod 202; four electric push rods 201 are fixed to the square frame 3; the telescopic end of each electric push rod 201 is fixed with a round rod 202, and the round rod 202 is plugged into the sand box 1, and the sand box 1 and the square frame 3 are fixed by the round rod 202.

[0020] The cylinders 4 on the same side are staggered.

[0021] Cylinder 2 4 is rotatably connected to ring 1 5 .

[0022] The end of the round rod 202 is chamfered to make it easier for the round rod 202 to be inserted into the flask 1 .

[0023] The foundry is equipped with a crane for transporting the sand box 1 and other objects. When the equipment needs to be turned over, the four cranes are manually fixed on the four rings 2 6, and the equipment is lifted into the air by the four cranes. Then the two cranes at the front drive the corresponding rings 2 6 to move upward, and the two cranes at the back slowly lower the corresponding rings 2 6, so that the equipment is rotated to the position shown in FIG. Figure 6 The round rod 202 is then controlled by the electric push rod 201 to move away from the sand box 1 so that the round rod 202 stops fixing the sand box 1 on the frame 3. Since the cylinder 1-2 is set at the eccentric position of the sand box 1, the gravity of the upper part of the sand box 1 is greater than the gravity of the lower part. Under the action of gravity, the sand box 1 will rotate downward 180 degrees around the cylinder 1-2. At this time, the opening of the sand box 1 faces forward. The round rod 202 is then controlled by the electric push rod 201 to be inserted back into the sand box 1 so that the round rod 202 fixes the sand box 1 on the frame 3 again. After that, the two hoists at the front slowly lower the corresponding circular ring 2 6, and the two hoists at the rear drive the corresponding circular ring 2 6 to move upward, so that the square frame 3 rotates back to the horizontal state, and the square frame 3 drives the sand box 1 to rotate to the horizontal state. At this time, the opening of the sand box 1 faces downward, thereby completing the flipping operation of the sand box 1; when in use, the eccentrically arranged cylinder 1 2 and the square frame 3 are matched, and the flipping operation of the sand box 1 can be completed with the help of the existing crane hoist in the factory, making the flipping operation simpler and more convenient, which is conducive to improving production efficiency.

[0024] likeFigure 7 As shown, if the two cylinders two 4 are in alignment after the device is rotated to the vertical state, the two spreaders fixed on the corresponding ring two 6 will overlap together, and even appear to be intertwined with each other. Therefore, the two cylinders two 4 are staggered, and after the device is rotated to the vertical state, the spreaders fixed on the ring two 6 will be in a staggered state, thereby avoiding the phenomenon of spreader entanglement. At the same time, the cylinder two 4 and the ring one 5 are arranged in a rotating connection, and during the rotation of the device driven by the spreader, the ring one 5 and the ring two 6 can adaptively rotate around the cylinder two 4, so that the spreader will not be twisted with the rotation of the device, which is beneficial to improve the stability during the lifting and turning process.

[0025] In example 2, on the basis of example 1, as shown in Figures 2-7 The buffer assembly includes a ring three 203, a connecting block 204, and a movable block one 205. Two ring threes 203 are bolted on the cylinder one 2, and the ring three 203 is in rotating connection with the corresponding cylinder one 2. The ring three 203 is made of alloy material. One connecting block 204 is fixed on each ring three 203, and the connecting block 204 is in contact with the corresponding cylinder one 2. One movable block one 205 is fixed on each cylinder one 2, and the movable block one 205 is in contact with the corresponding ring three 203. A plurality of through grooves one 91 are formed on each movable block one 205. The inside of the ring three 203 is filled with pressure oil. When the cylinder one 2 drives the movable block one 205 to rotate, the pressure oil will pass through the through grooves one 91.

[0026] The auxiliary assembly comprises the movable block two 206, the spring one 207, the movable block three 208 and the spring two 209; seven movable block two 206 are slidably connected between each cylinder one 2 and the corresponding ring three 203; a plurality of through grooves two 92 are formed in each movable block two 206; each adjacent two movable block two 206 are in contact; each connecting block 204 is in contact with the corresponding movable block two 206; each movable block one 205 is in contact with the corresponding movable block two 206; two spring one 207 are fixedly connected between each adjacent two movable block two 206, and the spring one 207 is made of alloy material; two spring one 207 are also fixedly connected between each connecting block 204 and the corresponding movable block two 206; seven movable block three 208 are slidably connected between each cylinder one 2 and the corresponding ring three 203; a plurality of through grooves three 93 are formed in each movable block three 208; two spring two 209 are fixedly connected between each adjacent two movable block three 208; two spring two 209 are also fixedly connected between each connecting block 204 and the corresponding movable block three 208, and the spring two 209 is made of alloy material.

[0027] The movable block two 206 is provided with an avoiding hole one 94, and the movable block three 208 is provided with an avoiding hole two 95; the avoiding hole one 94 is used for accommodating the spring one 207; and the avoiding hole two 95 is used for accommodating the spring two 209.

[0028] The movable block two 206 and the movable block three 208 are both provided with smooth surfaces, so as to reduce friction.

[0029] The surface of the square frame 3 is provided with an anti-rust coating, so as to prevent rust.

[0030] When the sand box 1 rotates under the action of gravity, small amplitude reciprocating swing phenomenon still occurs after the sand box 1 rotates one hundred and eighty degrees under the action of inertia, and the sand box 1 needs to be stopped swinging before the circular rod 202 can turn the sand box 1, so that the sand box 1 is turned over again, which wastes a lot of time, and the reciprocating swing of the sand box 1 also leads to the decrease of hoisting stability, therefore, the buffering assembly is arranged on the square frame 3, when the sand box 1 rotates under the action of gravity, the sand box 1 drives the cylinder one 2 to rotate, the cylinder one 2 drives the movable block one 205 to rotate, so that the movable block one 205 extrudes the pressure oil on the side of the movable block one 205, so that the pressure oil flows into the other side through the through groove one 91 of the movable block one 205, because the through groove one 91 is relatively small, the pressure oil passing through the through groove one 91 will be subjected to a greater resistance, so that the sand box 1, the cylinder one 2 and the movable block one 205 can be buffered through the resistance, so that the sand box 1 can rotate one hundred and eighty degrees slowly, and the reciprocating swing phenomenon can be greatly reduced, which is beneficial to improve the efficiency; in use, the sand box 1 in the rotating process is buffered and decelerated through the cooperation of the movable block one 205 and the pressure oil, which can greatly reduce the reciprocating swing phenomenon and is beneficial to improve the efficiency.

[0031] When the sand box 1 rotates under the action of gravity, the sand box 1 drives the cylinder one 2 to rotate, and the cylinder one 2 drives the movable block one 205 to rotate. If the movable block one 205 rotates towards one side of the connecting block 204, the connecting block 204 will block and limit the movable block one 205, causing the sand box 1 to fail to rotate one hundred and eighty degrees, thereby causing the turnover operation to fail. Therefore, the auxiliary assembly is arranged on the circular ring three 203. When the circular rod 202 stops fixing the sand box 1, the spring one 207 in the initial compressed state rebounds and drives the movable block two 206 to move, so that the movable block two 206 exerts a pushing force on the movable block one 205 in the direction away from the connecting block 204, thereby causing the sand box 1 to drive the movable block one 205 to rotate away from the connecting block 204, thereby effectively avoiding the problem of the connecting block 204 blocking and limiting the movable block one 205, so that the sand box 1 can be stably turned one hundred and eighty degrees. At the same time, the pressure oil flows into the gap between the movable block two 206 through the through groove two 92.

[0032] In the last stage of the rotation of the sand box 1 under the action of gravity, the movable block one 205 contacts the movable block three 208 and drives the movable block three 208 to move towards the connecting block 204, and at the same time, the spring two 209 is compressed. In this process, the hydraulic oil in the gap between the movable block three 208 needs to continuously pass through the through groove three 93, so that each movable block three 208 will be subjected to a larger resistance, and the resistance of each movable block three 208 will act on the movable block one 205, thereby greatly increasing the resistance received by the movable block one 205, and thereby the buffering effect of the sand box 1 in the last stage can be greatly increased. After all the movable blocks three 208 are extruded on the connecting block 204, the movable block one 205 just moves to the vertical state. At this time, the connecting block 204 and the movable block three 208 cooperate to block and limit the movable block one 205, so that it cannot continue to move, that is, the sand box 1 just turns one hundred and eighty degrees and can immediately stop rotating, and will not appear reciprocating swing phenomenon; when in use, the movable block three 208 and the spring two 209 cooperate to greatly increase the resistance received by the movable block one 205 in the last stage of movement, so that the sand box 1 rotates at a very small speed in the last stage. After the movable block three 208 is stacked, it can cooperate with the connecting block 204 to limit the sand box 1, so that the sand box 1 can immediately stop rotating after turning one hundred and eighty degrees, and will not appear reciprocating swing phenomenon, which is beneficial to improve the turnover efficiency and hoisting stability.
