[0023] 2. When the inner top plate clamps the air compressor housing, the operator starts the second motor. The output shaft of the second motor drives the third gear to rotate through the second reducer. Under the action of the third gear and the second gear, the mounting shaft drives the rotating plate to rotate, so that the outer clamping plate rotates away from the housing with the mounting shaft as the reference. This makes it easier for the operator to carry out construction work on the outer surface of the housing without occupying construction space. When the outer clamping plate clamps the outer surface of the housing, the operator controls the output end of the first cylinder to retract, so that the inner top plate moves into the connection hole. This also makes it easier for the operator to carry out construction work on the inside of the housing without occupying construction space.

[0024] 3. After determining the structure of the shell, the operator disassembles the wing-shaped studs on the top block corresponding to the positions of the protrusions and grooves on the inner and outer surfaces of the shell. When the top block contacts the groove of the shell, the operator activates the electric guide rail, which moves the lifting plate to the corresponding position of the top block. Then, the operator activates the second cylinder, whose output end moves the lifting plate. After receiving the thrust, the top block moves the slider along the slide groove, thus moving one side of the top block into the groove and pressing against the inner wall surface of the groove. When the top block contacts the protrusion of the shell, it moves along the slide groove after receiving the thrust, and at the same time fits against the surface of the protrusion. This allows the outer clamping plate and the inner top plate to clamp shells with different protrusion and groove positions, thus enabling the clamping of shells of different specifications.

[0025] 4. When the lifting plate moves, it can drive the lifting frame to push the lower surface of the top block. At the same time, the operator can start the second double-headed cylinder to drive the two adjacent lifting frames to move relative to each other. This allows the operator to adjust the pushing range of the lifting frame on the top block, and thus adjust the number of top blocks to be moved according to the length of the groove.

[0038] The surface of rotary table 5 one end is provided with connecting hole 501, and the outer surface of rotary table 5 one side is installed with outer clamping assembly 3 for clamping the outer surface of air compressor shell, and inner clamping assembly 4 for clamping the inner wall surface of air compressor shell is installed in connecting hole 501.

[0039] The outer surface of rotary table 5 other side is sleeved with outer gear ring 6, and first speed reducer 7 is fixedly installed on the side of vertical plate 2 close to outer gear ring 6, and first motor 701 is fixedly installed on the lower surface of first speed reducer 7, and the input end of first speed reducer 7 is fixedly connected with the output shaft end of first motor 701, and first gear 702 is sleeved with the output end of first speed reducer 7, and first gear 702 is engaged with outer gear ring 6.

[0040] Through the above technical scheme, when using, first of all, staff uses lifting equipment to move air compressor shell to the position of outer clamping assembly 3, then staff starts outer clamping assembly 3, so that it clamps the outer surface of air compressor shell, then staff starts first motor 701, and the output end of first motor 701 drives first gear 702 to reciprocate under the action of first speed reducer 7, under the cooperation of first gear 702 and outer gear ring 6, rotary table 5 reciprocates in installation hole 201, so that outer clamping assembly 3 reciprocates with rotary table 5, so that it clamps air compressor shell to turn over, facilitate staff to carry out construction to the inner surface of air compressor shell, after the construction to the inner surface of air compressor shell is completed, staff moves inner clamping assembly 4 to the inside of air compressor shell, then staff starts inner clamping assembly 4, so that it clamps the inner surface of air compressor shell, then staff controls outer clamping assembly 3, so that it is separated from air compressor shell and moves to the original position, at this time, inner clamping assembly 4 clamps the inner surface of air compressor shell, without staff using lifting equipment to take down the shell from outer clamping assembly 3, can carry out construction to the inside of air compressor shell, the operation steps are very simple, greatly improve the processing efficiency of staff.

[0041] As Figure 1 , Figure 4As shown, in the embodiment, the outer clamping assembly 3 comprises two mounting plates 301, both of which are fixedly installed on one side of the outer surface of the turntable 5, and both of which are fixedly installed with two mounting blocks 302 on the side away from the stand plate 2. Between every two adjacent mounting blocks 302, a rotating plate 303 is movably installed, and both sides of the two rotating plates 303 away from each other are fixedly installed with an electric push rod 304. The output ends of the two electric push rods 304 pass through the corresponding rotating plates 303 and are fixedly installed with an outer clamping plate 305. After the air compressor shell is moved between the two outer clamping plates 305, the worker starts the electric push rod 304, so that the output end drives the outer clamping plate 305 to move, so that the outer clamping plate 305 clamps the outer surface of the air compressor shell, facilitating the worker to work on the inside of the air compressor shell.

[0042] The inner clamping assembly 4 comprises a stand 401 movably installed in the connecting hole 501, and the stand 401 is fixedly installed with a first double-head air cylinder 402 on the side close to the outer clamping plate 305. The two output ends of the first double-head air cylinder 402 are fixedly installed with an inner top plate 403. After the worker completes the construction on the inside of the air compressor shell, the worker moves the inner top plate 403 into the air compressor shell, then starts the first double-head air cylinder 402, so that the output end drives the inner top plate 403 to move, so that the inner top plate 403 clamps the inner surface of the air compressor shell, and finally the worker controls the electric push rod 304, so that the output end drives the inner top plate 403 to reset. At this time, since the inner top plate 403 clamps the air compressor shell, the shell is still clamped and fixed, facilitating the worker to work on the outer surface of the shell.

[0043] As shown, Figures 4-6 It should be noted that a mounting shaft 306 is rotatably installed between every two adjacent mounting blocks 302, and the two rotating plates 303 are respectively sleeved on the shaft body of the corresponding mounting shaft 306, and the lower ends of the two mounting shafts 306 pass through the corresponding mounting blocks 302 and are sleeved with a second gear 307.

[0044] The lower surface of the two mounting plates 301 is fixedly provided with a second speed reducer 309 through a support 308, and the second speed reducer 309 is fixedly provided with a second motor 3010 away from each other. The input end of the second speed reducer 309 is fixedly connected with the output shaft end of the second motor 3010. The output end of the two second speed reducers 309 is provided with a third gear 3011, and the two third gears 3011 are respectively engaged with the corresponding second gears 307. When the inner top plate 403 clamps the air compressor shell, the worker starts the second motor 3010, and the output shaft of the second motor 3010 drives the third gear 3011 to rotate under the action of the second speed reducer 309. Under the cooperation of the third gear 3011 and the second gear 307, the mounting shaft 306 drives the rotating plate 303 to rotate, so that the outer clamping plate 305 rotates away from the shell with the mounting shaft 306 as the reference, so as to make the outer clamping plate 305 not occupy the construction space, and the worker is more convenient to construct the outer surface of the shell.

[0045] The inner wall of the connecting hole 501 is fixedly provided with a first air cylinder 404, and the output end of the first air cylinder 404 is fixedly connected with the stand 401. When the outer clamping plate 305 clamps the outer surface of the shell, the worker controls the output end of the first air cylinder 404 to retract, so that the inner top plate 403 moves to the inside of the connecting hole 501, so that the inner top plate 403 does not occupy the construction space, and the worker is more convenient to construct the inside of the shell.

[0046] As shown in Figure 4 , Figure 7 , Figure 8 When specifically setting, the two outer clamping plates 305 and the inner top plate 403 are provided with mounting grooves 8 on the surface close to one side of the rotating table 5, and the inner wall of each mounting groove 8 is provided with a sliding groove 801 on both sides of the surface, and a sliding block 802 is slidably installed in each sliding groove 801, and a top block 803 is fixedly installed between every two opposite sliding blocks 802.

[0047] The inner wall of each mounting groove 8 is fixedly provided with an electric guide rail 804, and the moving end of each electric guide rail 804 is fixedly provided with a second air cylinder 805 through a moving seat, and the output end of each second air cylinder 805 is fixedly provided with a lifting plate 806.

[0048] The outer clamping plate 305 and the inner top plate 403 are fixedly installed with a connecting block 807 close to one side of the corresponding top block 803. The upper surface of each connecting block 807 is provided with a through hole. The upper surface of each top block 803 is provided with a threaded hole. Each through hole is inserted and matched with a butterfly-shaped stud 808. The threaded section of each butterfly-shaped stud 808 is threadedly arranged in the corresponding threaded hole. After determining the structure of the shell, the staff disassembles the butterfly-shaped stud 808 above the top block 803 corresponding to the position of the convex and groove on the inner and outer surfaces of the shell. When the top block 803 contacts the groove of the shell, the staff drives the moving end of the electric guide rail 804 to move the lifting plate 806 to the position of the corresponding top block 803. Then the staff drives the output end of the second air cylinder 805 to move the lifting plate 806. After receiving the thrust, the top block 803 drives the sliding block 802 to move along the direction of the sliding groove 801. Thus, the side of the top block 803 moves into the groove and tightly presses the inner wall surface of the groove. When the top block 803 contacts the convex position of the shell, the top block 803 moves along the direction of the sliding groove 801 and is attached to the surface of the convex position. Thus, the outer clamping plate 305 and the inner top plate 403 can clamp the shell with different positions of the convex and groove. Thus, the shell with different specifications can be clamped.

[0049] As shown in Figure 7 , Figure 9 , it can be understood that in the present application, each lifting plate 806 is fixedly installed with a second double-head air cylinder 809 close to one side of the corresponding top block 803. The two output ends of each second double-head air cylinder 809 are fixedly installed with a lifting frame 8010. Every two adjacent lifting frames 8010 are inserted and matched with each other. When the lifting plate 806 moves, the lifting frame 8010 is driven to push the lower surface of the top block 803. At the same time, the staff drives the output end of the second double-head air cylinder 809 to drive the adjacent two lifting frames 8010 to move relatively. Thus, the staff can adjust the pushing range of the lifting frame 8010 to the top block 803. Thus, the staff can adjust the number of top blocks 803 to be moved according to the length of the groove.

[0050] As shown in Figure 7 , in the specific setting, the inner wall of each sliding groove 801 is fixedly installed with a sliding rod 8011 between the two sides. Each sliding block 802 is slidingly arranged in the middle part of the corresponding sliding rod 8011. The rod body of each sliding rod 8011 is sleeved with a first spring 8012 on both sides. By setting the first spring 8012, the top block 803 can be quickly reset after clamping the convex or groove of the shell. The staff does not need to manually reset the top block 803, which reduces the labor intensity of the staff.

[0051] As shown in Figure 7 , Figure 8As shown, each top block 803 is provided with a support groove 8031 on each side surface, each support groove 8031 is provided with a limiting groove 8032 on each side surface of the inner wall, each limiting groove 8032 is fixedly installed with a limiting block 8033, and each two opposite limiting blocks 8033 are fixedly installed with a pressing block 8034.

[0052] Each limiting groove 8032 is fixedly installed with a limiting rod 8035 between the inner walls on both sides, each limiting block 8033 is slidingly arranged on one side of the corresponding limiting rod 8035, and each limiting rod 8035 is sleeved with a second spring 8036 on the other side of the rod body. When the top block 803 is tightened against the protrusions or grooves of the shell, the pressing block 8034 can move in the direction of the limiting groove 8032 under the pushing of the inner wall surface of the mounting groove 8 or the inner wall surface of the groove, the second spring 8036 is compressed and forced, and the pressing block 8034 is given an opposite pushing force, so that the upper surface of the pressing block 8034 is tightly attached to the inner wall of the mounting groove 8 or the inner wall of the groove, thereby preventing the top block 803 from being easily shaken when it is tightened against the protrusions or grooves on the shell, and enhancing the tightening effect of the top block 803.

[0053] The upper surface of each pressing block 8034 is an arc surface. By setting the upper surface of the pressing block 8034 as an arc surface, the pressing block 8034 can be prevented from being stuck when entering the inner wall of the mounting groove 8 or the groove.

[0054] The working principle of the air compressor shell turnover clamp is as follows:

[0055] In use, first, the worker uses the hoisting equipment to move the air compressor shell to the position of the outer clamping assembly 3, then the worker starts the outer clamping assembly 3 to clamp the outer surface of the air compressor shell, then the worker starts the first motor 701, and the output end of the first motor 701 drives the first gear 702 to reciprocatingly rotate under the action of the first speed reducer 7, and under the cooperation of the first gear 702 and the outer gear ring 6, the rotating table 5 reciprocatingly rotates in the mounting hole 201, so that the outer clamping assembly 3 reciprocatingly rotates with the rotating table 5, thereby clamping the air compressor shell to turn it over, facilitating the worker to work on the inner surface of the air compressor shell. After the work on the inner surface of the air compressor shell is completed, the worker moves the inner clamping assembly 4 to the inside of the air compressor shell, then the worker starts the inner clamping assembly 4 to clamp the inner surface of the air compressor shell, then the worker controls the outer clamping assembly 3 to move to the original position after being separated from the air compressor shell, at this time, the inner clamping assembly 4 clamps the inner surface of the air compressor shell, so that the worker can work on the inside of the air compressor shell without the need to use the hoisting equipment to take the shell off the outer clamping assembly 3, which is very simple in operation steps and greatly improves the processing efficiency of the worker.

[0056] The above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model, and for ordinary skilled in the art, on the basis of the above description, other different forms of changes or variations can be made, and all the embodiments cannot be exhausted here, and all the changes or variations derived from the technical scheme of the utility model still fall within the protection scope of the utility model.
