Description

Technical Field

[0001] The present invention relates to the technical field of assembly devices, and more specifically, to a cylinder assembly device. Background Art

[0002] A cylinder refers to a cylindrical metal part that guides a piston to perform linear reciprocating motion in the cylinder. A cylinder usually consists of three parts: a cylinder head, a cylinder block, and a cylinder seat, or consists of two parts: a cylinder head and a cylinder block. In order to prevent axial movement, a snap ring is usually installed in the hole groove of the cylinder head or cylinder block through a snap ring assembly machine.

[0003] However, when assembling through a snap ring assembly machine, when the cylinder is placed on the bottom mold, positioning is achieved by inserting the mounting holes of the cylinder into two positioning posts on the bottom mold. When encountering a cylinder with insufficient machining accuracy, there will be a deviation between the mounting holes and the positioning posts, resulting in unsmooth insertion and affecting the installation efficiency between the cylinder and the positioning posts; at the same time, when feeding the snap ring, the snap ring is automatically fed by placing it on the feeding post. After the snap ring on the feeding post is assembled, the operator needs to place the snap ring on the feeding post one by one for feeding, which affects the processing speed; also, when different pressing molds need to be replaced, the corresponding storage rods need to be replaced. When replacing the pressing mold and the storage rod, multiple complex steps are required for disassembly and replacement, and each component replacement step takes a long time, resulting in a reduction in the overall replacement efficiency.

[0038] Specifically, as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 10 and Figure 11As shown, a first lead screw 206 is rotatably connected in the mounting base 201. The mounting block 202 is threadedly connected to the first lead screw 206. A hand wheel 207 is fixedly connected to the first lead screw 206. A first motor 308 is mounted on the mounting plate 301. The rotating shaft 302 is fixedly connected to the output shaft of the first motor 308. A mounting frame 707 is mounted on the workbench 1. A third hydraulic component 708 is mounted in the mounting frame 707. The placing frame 701 is fixedly connected to the telescopic end of the third hydraulic component 708. A third lead screw 703 is rotatably connected in the placing frame 701. A fourth lead screw 705 is rotatably connected in the placing frame 701. Two of the clamping plates 702 are threadedly connected to the third lead screw 703, and the other two clamping plates 702 are threadedly connected to the fourth lead screw 705. The thread directions at both ends of the third lead screw 703 and the fourth lead screw 705 are opposite. A second motor 704 is mounted in the placing frame 701. The third lead screw 703 is fixedly connected to the output shaft of the second motor 704. A third motor 706 is mounted in the placing frame 701. The fourth lead screw 705 is fixedly connected to the output shaft of the third motor 706. Two guide plates 709 are fixedly connected to the bottom of the placing frame 701. The guide plates 709 are slidably connected to the mounting frame 707. First, place the cylinder workpiece to be assembled between the four clamping plates 702 on the placing frame 701. Then, by starting the second motor 704, when the output shaft of the second motor 704 rotates, it drives the third lead screw 703 to rotate. The third lead screw 703 threadedly drives two of the clamping plates 702 to slide towards each other. At the same time, start the third motor 706. When the output shaft of the third motor 706 rotates, it drives the fourth lead screw 705 to rotate. The fourth lead screw 705 threadedly drives the other two clamping plates 702 to slide towards each other, so that the four clamping plates 702 gradually approach to clamp and fix the cylinder. By using the third lead screw 703 and the fourth lead screw 705 to drive the four clamping plates 702 respectively to fix the cylinder, it is convenient to quickly fix the cylinder, improving the fixing efficiency. At the same time, when fixing cylinders of different models, there is no need to replace the lower die, improving the practicability. At this time, by starting the third hydraulic component 708, when the telescopic end of the third hydraulic component 708 extends, it drives the placing frame 701 to slide upward. When the placing frame 701 moves upward, it drives the guide plates 709 to slide with the mounting frame 707. The setting of the guide plates 709 makes the movement of the placing frame 701 more stable. At the same time, the placing frame 701 drives the clamped cylinder to move upward. At the same time, start the first hydraulic component 204. When the telescopic end of the first hydraulic component 204 extends, it drives the pressing die 205 to move downward. When the top of the cylinder contacts the bottom of the connecting seat 203, at this time, the pressing die 205 presses the snap ring in the push plate 401 into the cylinder to complete the assembly. When it is necessary to adjust the height of the connecting seat 203, just drive the first lead screw 206 to rotate through the hand wheel 207, so that the first lead screw 206 drives the mounting block 202 to slide in the mounting base 201, and the height of the connecting seat 203 can be adjusted.

[0039] Specifically, as Figure 1 , Figure 3 , Figure 5 and Figure 6 shown, the mounting structure 6 includes two mounting rods 601 fixedly connected to the connecting seat 203 and clamping rods 602 respectively clamped on the two mounting rods 601. The mounting rods 601 are inserted into the mounting block 202. Two guide rails 603 are fixedly connected inside the mounting block 202. The clamping rods 602 are slidably connected to the guide rails 603. A driving rod 604 is slidably connected inside the mounting block 202. The clamping rods 602 are slidably connected to the driving rod 604. The cross-section of the driving rod 604 is in a "Y" shape. A second knob 605 is threadedly connected to the driving rod 604. A fixing rod 606 is fixedly connected to the mounting block 202. Two jacks 607 are provided on the fixing rod 606. The second knob 605 is inserted into one of the jacks 607. When it is necessary to replace components such as the pressing die 205 and the storage rod 304 according to different specifications of the snap ring, by rotating the second knob 605, the second knob 605 cooperates with the driving rod 604 and no longer inserts into the jack 607 on the left side of the fixing rod 606. Then, by pushing the driving rod 604, the driving rod 604 is slidably engaged with the inclined groove on the clamping rod 602, so that the two clamping rods 602 slide towards each other in the two guide rails 603 and no longer engage with the mounting rod 601. When the driving rod 604 moves to a certain position, the second knob 605 is inserted into the other jack 607. At this time, the connecting seat 203 can be detached from the mounting block 202. The connecting seat 203 equipped with different specifications of the storage rod 304 and the pressing die 205 is installed on the mounting block 202. After the mounting rod 601 is inserted into the mounting block 202, by driving the driving rod 604 through the second knob 605, the driving rod 604 drives the two clamping rods 602 to slide away from each other in the two guide rails 603 and engage with the mounting rod 601. By driving the two clamping rods 602 to engage with the mounting rod 601 simultaneously through the driving rod 604, the disassembly and assembly efficiency is improved when disassembling and assembling the connecting seat 203. Then, by inserting the second knob 605 into the jack 607 on the left side, it is convenient to fix the driving rod 604 and prevent the slid driving rod 604 from sliding. At the same time, components such as the pressing die 205 that can be replaced are installed on the connecting seat 203. When it is necessary to replace components such as the pressing die 205 and the storage rod 304 with different specifications, only the connecting seat 203 needs to be detached from the mounting block 202 and the connecting seat 203 equipped with different specifications of components such as the pressing die 205 is installed on the mounting block 202, which improves the replacement efficiency.

[0040] Specifically, as Figure 3 , Figure 7 , Figure 8 , Figure 9 and Figure 12As shown, a falling prevention structure 5 is provided in the storage rod 304. The falling prevention structure 5 includes two stoppers 501 slidably connected to the storage rod 304 and a driving shaft 502 rotatably connected to the stopper 501. A second lead screw 505 is threadedly connected in the storage rod 304. The bottom of the second lead screw 505 is fixedly connected to a turntable 503. Two driving grooves 504 are provided on the turntable 503. The two driving shafts 502 are respectively in rolling cooperation with the two driving grooves 504. The top of the second lead screw 505 is fixedly connected to a rotating rod 506. A material pushing structure 4 is provided in the connecting seat 203. The material pushing structure 4 includes a pushing plate 401 slidably connected to the connecting seat 203 and a connecting rod 402 fixedly connected to the pushing plate 401. An installation sleeve 403 is fixedly connected to the connecting seat 203. A second hydraulic member 404 is installed in the installation sleeve 403. The connecting rod 402 is fixedly connected to the telescopic end of the second hydraulic member 404. After a snap ring is assembled, by starting the second hydraulic member 404, when the telescopic end of the second hydraulic member 404 extends, it drives the pushing plate 401 to move through the connecting rod 402. When the pushing plate 401 moves below the left storage rod 304, since the rotating block 303 is provided with a "C"-shaped through hole, and the connecting seat 203 is provided with two "C"-shaped through holes, one is below the first hydraulic member 204, and the other is below the left storage rod 304. When the "C"-shaped through hole on the pushing plate 401 moves to correspond to the "C"-shaped through hole below the storage rod 304, the snap ring will slide into the "C"-shaped through hole on the pushing plate 401. Then, by contracting the second hydraulic member 404, the pushing plate 401 drives the snap ring to move below the pressing die 205. Then, the first hydraulic member 204 drives the pressing die 205 to move to assemble the snap ring and the cylinder. After all the snap rings on the left storage rod 304 are assembled, by starting the first motor 308, when the output shaft of the first motor 308 rotates, it drives the rotating shaft 302 to rotate. After the rotating shaft 302 rotates 180 degrees, the storage rod 304 is rotated to the right, and at the same time, the storage rod 304 with the snap ring installed on the right rotates to the left. Then, by rotating the first knob 307, the first knob 307 is no longer in contact with the positioning block 306. At this time, the guide sleeve 305 of the right storage rod 304 slips off from the positioning block 306, and the right storage rod 304 is disassembled. Another storage rod 304 with a snap ring installed is installed on the rotating block 303. During assembly, the rotating block 303 cooperates with the storage rod 304 to rotate, and the storage rod 304 with the snap ring pre-installed and the storage rod 304 on the rotating block 303 are replaced, which is convenient for quickly feeding the snap ring and improves the processing efficiency. At the same time, after the storage rod 304 is installed on the rotating block 303, the rotating rod 506 drives the second lead screw 505 to rotate. When the second lead screw 505 rotates, it is in threaded cooperation with the storage rod 304. At the same time, the second lead screw 505 drives the turntable 503 to rotate. When the turntable 503 rotates, the two driving shafts 502 are in rolling cooperation in the driving grooves 504.The two drive shafts 502 drive the two stoppers 501 to move towards each other and contract into the storage rod 304, which will not affect the slipping of the circlip. At the same time, the stopper 501 extends out of the storage rod 304. During the handling of the storage rod 304, the circlip will be blocked by the stopper 501 to prevent it from slipping off the storage rod 304.

[0041] When the present invention is in use, first, the cylinder workpiece to be assembled is placed between the four clamping plates 702 on the placement frame 701. Then, by starting the second motor 704, when the output shaft of the second motor 704 rotates, it drives the third lead screw 703 to rotate. The third lead screw 703 threadedly drives two of the clamping plates 702 to slide towards each other. At the same time, the third motor 706 is started. When the output shaft of the third motor 706 rotates, it drives the fourth lead screw 705 to rotate. The fourth lead screw 705 threadedly drives the other two clamping plates 702 to slide towards each other, so that the four clamping plates 702 gradually approach to clamp and fix the cylinder. By using the third lead screw 703 and the fourth lead screw 705 to drive the four clamping plates 702 respectively to fix the cylinder, it is convenient to quickly fix the cylinder, improving the fixing efficiency. At the same time, when fixing cylinders of different models, there is no need to replace the lower die, improving the practicability. At this time, by starting the third hydraulic component 708, when the telescopic end of the third hydraulic component 708 extends, it drives the placement frame 701 to slide upward. When the placement frame 701 moves upward, it drives the guide plate 709 to slide with the mounting frame 707. The setting of the guide plate 709 makes the movement of the placement frame 701 more stable. At the same time, the placement frame 701 drives the clamped cylinder to move upward. At the same time, the first hydraulic component 204 is started. When the telescopic end of the first hydraulic component 204 extends, it drives the pressing die 205 to move downward. When the top of the cylinder contacts the bottom of the connecting seat 203, at this time, the pressing die 205 presses the circlip in the push plate 401 into the cylinder to complete the assembly. When it is necessary to adjust the height of the connecting seat 203, only need to drive the first lead screw 206 to rotate by the handwheel 207, so that the first lead screw 206 drives the mounting block 202 to slide in the mounting seat 201, and the height of the connecting seat 203 can be adjusted.

[0042] When a snap ring assembly is completed, by starting the second hydraulic component 404, when the telescopic end of the second hydraulic component 404 extends, it drives the push plate 401 to move through the connecting rod 402. When the push plate 401 moves below the left storage rod 304, since the rotating block 303 is provided with a "C"-shaped through hole, and the connecting seat 203 is provided with two "C"-shaped through holes, one is below the first hydraulic component 204, and the other is below the left storage rod 304. When the "C"-shaped through hole on the push plate 401 moves to correspond to the "C"-shaped through hole below the storage rod 304, the snap ring will slide into the "C"-shaped through hole on the push plate 401. Then, by the contraction of the second hydraulic component 404, the push plate 401 drives the snap ring to move below the pressing die 205. Then, the first hydraulic component 204 drives the pressing die 205 to move to assemble the snap ring and the cylinder. After all the snap rings on the left storage rod 304 are assembled, by starting the first motor 308, when the output shaft of the first motor 308 rotates, it drives the rotating shaft 302 to rotate. After the rotating shaft 302 rotates 180 degrees, the storage rod 304 is rotated to the right, and at the same time, the storage rod 304 with snap rings on the right rotates to the left. Then, by rotating the first knob 307, the first knob 307 is no longer in contact with the positioning block 306. At this time, the guide sleeve 305 of the right storage rod 304 slips off from the positioning block 306 to disassemble the right storage rod 304. Another storage rod 304 with snap rings is installed on the rotating block 303. During assembly, the rotating block 303 cooperates with the storage rod 304 to rotate to replace the storage rod 304 with the pre-installed snap rings on the rotating block 303 and the storage rod 304 on the rotating block 303, which is convenient for quickly loading the snap rings and improves the processing efficiency. At the same time, after the storage rod 304 is installed on the rotating block 303, the second lead screw 505 is driven to rotate by the rotating rod 506. When the second lead screw 505 rotates, it is in threaded cooperation with the storage rod 304. At the same time, the second lead screw 505 drives the turntable 503 to rotate. When the turntable 503 rotates, the two drive shafts 502 roll and cooperate in the drive groove 504, so that the two drive shafts 502 drive the two stoppers 501 to move towards each other and contract into the storage rod 304, which will not affect the sliding of the snap ring. At the same time, the stopper 501 extends out of the storage rod 304. During the handling of the storage rod 304, the snap ring will be blocked by the stopper 501 to prevent it from slipping off the storage rod 304;

[0043] When it is necessary to replace components such as the die holder 205 and the storage rod 304 according to snap rings of different specifications, by rotating the second knob 605, the second knob 605 is engaged with the drive rod 604 and no longer inserted into the jack 607 on the left side of the fixed rod 606. Then, by pushing the drive rod 604, the drive rod 604 is in sliding fit with the inclined slot on the locking rod 602, so that the two locking rods 602 slide towards each other in the two guide rails 603 and no longer engage with the mounting rod 601. When the drive rod 604 moves to a certain position, the second knob 605 is inserted into another jack 607. At this time, the connecting seat 203 can be detached from the mounting block 202. The connecting seat 203 equipped with snap rings and die holders 205 of different specifications is installed on the mounting block 202. After the mounting rod 601 is inserted into the mounting block 202, by driving the drive rod 604 through the second knob 605, the drive rod 604 drives the two locking rods 602 to slide away from each other in the two guide rails 603 and engage with the mounting rod 601. By driving the two locking rods 602 to engage with the mounting rod 601 simultaneously through the drive rod 604, the disassembly and assembly efficiency is improved when disassembling and assembling the connecting seat 203. Then, by inserting the second knob 605 into the jack 607 on the left side, it is convenient to fix the drive rod 604 and prevent the driven drive rod 604 from sliding. At the same time, replaceable components such as the die holder 205 are installed on the connecting seat 203. When it is necessary to replace components such as the die holder 205 and the storage rod 304 of different specifications, it is only necessary to detach the connecting seat 203 from the mounting block 202 and install the connecting seat 203 equipped with components such as the die holder 205 of different specifications on the mounting block 202, thus improving the replacement efficiency.
