Description

Technical Field

[0001] This utility model relates to the field of cylinder repair for air blowers, and in particular to a cylinder bushing disassembly tool. Background Technology

[0002] In glass bottle production, blow molding is the core process that gives the glass bottle its final shape. This process is completed by blowing with an air blower. To drive the air blower to move stably and reliably, the air blower is usually driven by a cylinder. One end of the cylinder has a movable groove, and inside the movable groove is a bushing. Inside the bushing is a piston rod that is slidably connected. The bushing is used to constrain the radial displacement of the piston rod and reduce the friction between the piston rod and the inside of the movable groove. Since the cylinder needs to withstand the pressure of the air blower, in order to improve the sealing of the cylinder, the other end of the cylinder is integrally molded with the cylinder body (i.e., the position away from the air blower), while the other end of the cylinder is detachably connected to the end cap with screws (i.e., the position close to the air blower).

[0003] The bushing is usually pressed into the movable groove with an interference fit. However, since the other end of the cylinder is not removable, when the bushing is severely worn and needs to be replaced, it cannot be pushed out from the other end like a conventional cylinder. If conventional puller pliers are used, they cannot effectively grasp the outer edge of the bushing, making it difficult to remove the bearing. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cylinder bushing disassembly tool. The purpose is to solve the technical problem that the bushing is usually pressed into the movable groove with an interference fit, but because the other end of the cylinder is not removable, when the bushing is severely worn and needs to be replaced, the bushing cannot be pushed out from the other end like a conventional cylinder. If conventional puller pliers are used, they cannot effectively grasp the outer edge of the bushing, making it difficult to disassemble the bearing.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A cylinder bushing disassembly tool includes a base, a clamping part on the top of the base for clamping the cylinder housing, a movable seat movably connected to the top of the base, and a disassembly screw rotatably connected to the top of the base. A transmission groove is formed inside the movable seat, and one end of the disassembly screw passes through the transmission groove, threadedly connecting the disassembly screw to the transmission groove. A disassembly insert is provided inside the movable seat, with its bottom end facing the movable groove of the cylinder housing. A movable cavity is formed at the top of the disassembly insert, and a receiving cavity communicating with the movable cavity is formed at the bottom of the disassembly insert. Movable blocks are hinged to both sides of the bottom of the disassembly insert, and a fixed magnet is provided on one side of each movable block. The fixed magnets on the movable blocks on both sides of the bottom of the disassembly insert attract each other. A push-in rod is threadedly connected inside the movable cavity, and a push-in head is provided at the bottom end of the push-in rod. The push-in head can pass through the receiving cavity, causing the push-in head to rotate the movable blocks on both sides of the bottom of the disassembly insert.

[0007] When the bushing needs to be disassembled, the clamping part clamps the cylinder housing. At this time, the disassembly pin is located above the movable groove of the cylinder housing, and the two movable blocks are in a closed state through the fixed magnet. When the disassembly screw is rotated, the disassembly screw drives the movable seat and the disassembly pin to move downward. The disassembly pin gradually passes through the bushing inside the movable groove, so that the movable block at the bottom of the disassembly pin is located below the bushing. Rotating the push rod, the push rod moves downward along the movable cavity, and the push head at the bottom of the push rod extends out from the receiving cavity at the bottom of the disassembly pin and presses downward. Since the movable blocks are hinged, the downward pressure applied by the push head will force the two movable blocks to overcome the attraction force of the magnet, and the two movable blocks will rotate outward and open. The block will abut against the bottom of the bushing. The operator rotates the disassembly screw in the opposite direction. The disassembly screw passes through the transmission groove inside the movable seat and the two are threaded together. Therefore, when the disassembly screw is rotated in the opposite direction, it will drive the movable seat, together with the fixed disassembly pin and its open movable block, to move away from the cylinder housing. Since the open movable block has been locked against the inner wall of the bushing, the strong linear pulling force generated by the outward movement of the movable seat will act directly on the inner wall of the bushing through the locked movable block, pulling out the bushing that is interference-fitted in the movable groove. Thus, even if it is not detachable at the other end of the cylinder, the bushing in the movable groove can be disassembled, which significantly shortens the time for replacing worn bushings and reduces the difficulty of maintenance and labor intensity.

[0008] Furthermore, in this application, a locking hole is provided on one side of the disassembly insert, the locking hole is connected to the movable cavity, and a locking bolt is threaded into the locking hole, the locking bolt abutting against the push rod.

[0009] When the operator rotates the push rod to move it downwards, the push head at the bottom of the push rod extends out of the receiving cavity. The push head forces the two movable blocks hinged at the bottom of the disassembly pin to overcome the magnetic attraction and open outwards. The locking bolt is screwed into the locking hole, so that the locking bolt abuts against the push rod. When the operator rotates the disassembly screw to apply a huge axial force to the movable seat and the disassembly pin, the locking bolt prevents the push rod from moving, preventing the push head from dislodging from the position of the two movable blocks due to displacement of the push rod, which would cause the bushing to fail to abut.

[0010] Furthermore, in this application, the bottom end of the push rod is provided with an installation slot, one end of the push head is provided with a connecting seat, one end of the connecting seat is provided with an installation pin, and the installation pin is detachably connected to the installation slot.

[0011] When the push-in head forces the two movable blocks hinged at the bottom of the disassembly pin to open outward, the movable blocks need to abut against the bushing. At this time, the push-in head needs to withstand the squeezing force of the two movable blocks, so the push-in head is prone to damage. Since the mounting pin and the mounting slot are detachably connected, it is convenient to replace the damaged push-in head.

[0012] Furthermore, in this application, a first mounting hole communicating with the mounting slot is provided on one side of the push rod, and a second mounting hole is provided on one side of the mounting post. A mounting bolt passes through the interior of the first mounting hole, and the mounting bolt is threadedly engaged with the second mounting hole.

[0013] Furthermore, in this application, the top-insertion head is cone-shaped, with its protruding surface facing the movable block. The top of the movable block is provided with a positioning groove, and the positioning grooves of the two movable blocks are interconnected, so that the positioning grooves of the two movable blocks match the shape of the top-insertion head.

[0014] Furthermore, in this application, the top of the base is provided with a rotating groove, the interior of the rotating groove is provided with a stabilizing bearing, and the other end of the disassembly screw is provided with a rotating end, which is rotatably connected to the inner ring of the stabilizing bearing.

[0015] Furthermore, in this application, the top of the base is provided with a plurality of guide slide rods, and the interior of the movable seat is provided with a plurality of guide grooves, and the plurality of guide slide rods are respectively slidably engaged with the plurality of guide grooves.

[0016] Furthermore, in this application, one end of the disassembly screw is provided with a rotating turntable, and the outer edge of the rotating turntable is provided with a plurality of rotating push arms.

[0017] Furthermore, in this application, a limiting protrusion is provided on the other side of the movable block, and the limiting protrusion is used to abut against the bottom of the bushing.

[0018] Furthermore, in this application, the clamping part includes two clamping seats, which are disposed on the top of the base and are spaced apart to form a clamping interval. A clamping hole is provided inside the clamping seat, and a clamping screw is threaded into the clamping hole. One end of the clamping screw passes through the clamping interval, and a clamping block is provided at one end of the clamping screw.

[0019] This utility model has the following beneficial effects:

[0020] When the bushing needs to be disassembled, the clamping part clamps the cylinder housing. At this time, the disassembly pin is located above the movable groove of the cylinder housing, and the two movable blocks are in a closed state through the fixed magnet. When the disassembly screw is rotated, the disassembly screw drives the movable seat and the disassembly pin to move downward. The disassembly pin gradually passes through the bushing inside the movable groove, so that the movable block at the bottom of the disassembly pin is located below the bushing. Rotating the push rod, the push rod moves downward along the movable cavity, and the push head at the bottom of the push rod extends out from the receiving cavity at the bottom of the disassembly pin and presses downward. Since the movable blocks are hinged, the downward pressure applied by the push head will force the two movable blocks to overcome the attraction force of the magnet, and the two movable blocks will rotate outward and open. The block will abut against the bottom of the bushing. The operator rotates the disassembly screw in the opposite direction. The disassembly screw passes through the transmission groove inside the movable seat and the two are threaded together. Therefore, when the disassembly screw is rotated in the opposite direction, it will drive the movable seat, together with the fixed disassembly pin and its open movable block, to move away from the cylinder housing. Since the open movable block has been locked against the inner wall of the bushing, the strong linear pulling force generated by the outward movement of the movable seat will act directly on the inner wall of the bushing through the locked movable block, pulling out the bushing that is interference-fitted in the movable groove. Thus, even if it is not detachable at the other end of the cylinder, the bushing in the movable groove can be disassembled, which significantly shortens the time for replacing worn bushings and reduces the difficulty of maintenance and labor intensity.

[0036] Reference Figures 1-10 In some specific embodiments, a cylinder bushing disassembly tool includes a base 1, a clamping part 4 on the top of the base 1 for clamping the cylinder housing 3, a movable seat 2 movably connected to the top of the base 1, and a disassembly screw 11 rotatably connected to the top of the base 1. A transmission groove 10 is formed inside the movable seat 2, and one end of the disassembly screw 11 passes through the transmission groove 10, so that the disassembly screw 11 is threadedly connected to the transmission groove 10. A disassembly insert 17 is provided inside the movable seat 2, with the bottom end of the disassembly insert 17 facing the movable groove 34 of the cylinder housing 3. The top of the column 17 has a movable cavity 18, and the bottom of the disassembly column 17 has a receiving cavity 33 that connects to the movable cavity 18. Movable blocks 29 are hinged to both sides of the bottom of the disassembly column 17. A fixed magnet 32 ​​is provided on one side of the movable block 29. The fixed magnets 32 of the movable blocks 29 on both sides of the bottom of the disassembly column 17 attract each other. A push rod 19 is threaded into the movable cavity 18. A push head 21 is provided at the bottom end of the push rod 19. The push head 21 can pass through the receiving cavity 33, so that the push head 21 drives the movable blocks 29 on both sides of the bottom of the disassembly column 17 to rotate.

[0037] With the above technical solution, when the bushing 35 needs to be disassembled, the clamping part 4 clamps the cylinder housing 3. At this time, the disassembly insert 17 is located above the movable groove 34 of the cylinder housing 3, and the two movable blocks 29 are in a combined state through the fixing magnet 32. When the disassembly screw 11 is rotated, the disassembly screw 11 drives the movable seat 2 and the disassembly insert 17 to move downward. The disassembly insert 17 gradually passes through the bushing 35 inside the movable groove 34, so that the movable block 29 at the bottom of the disassembly insert 17 is located below the bushing 35. Rotating the push rod 19, the push rod 19 moves downward along the movable cavity 18, and the push head 21 at the bottom of the push rod 19 extends out from the receiving cavity 33 at the bottom of the disassembly insert 17 and presses downward. Since the movable block 29 is hinged, the downward pressure applied by the push head 21 will force the two movable blocks 29 to overcome the attraction force of the magnet. The movable block 29 will rotate outward and open, and then abut against the bottom of the bushing 35. The operator rotates the disassembly screw 11 in the opposite direction. The disassembly screw 11 passes through the transmission groove 10 inside the movable seat 2 and the two are threaded together. Therefore, when the disassembly screw 11 is rotated in the opposite direction, it will drive the movable seat 2, together with the fixed disassembly insert 17 and its open movable block 29, to move away from the cylinder housing 3. Since the open movable block 29 has been clamped to the inner wall of the bushing 35, the strong linear pulling force generated by the outward movement of the movable seat 2 will act directly on the inner wall of the bushing 35 through the clamped movable block 29, pulling out the bushing 35 that is interference-fitted in the movable groove 34. Thus, even though it cannot be disassembled at the other end of the cylinder, the bushing 35 in the movable groove 34 can be disassembled, which significantly shortens the time for replacing the worn bushing 35 and reduces the difficulty of maintenance and labor intensity.

[0038] Reference Figures 1-7 In some specific embodiments, a locking hole 27 is provided on one side of the disassembly insert 17. The locking hole 27 is connected to the movable cavity 18. A locking bolt 28 is threaded into the locking hole 27. The locking bolt 28 abuts against the push rod 19.

[0039] With the above technical solution, when the operator rotates the push rod 19 to move it downward, the push head 21 at the bottom of the push rod 19 extends out of the receiving cavity 33. The push head 21 forces the two movable blocks 29 hinged at the bottom of the disassembly insert 17 to overcome the attraction force of the magnet and open outward. The locking bolt 28 is screwed into the locking hole 27, so that the locking bolt 28 abuts against the push rod 19. When the subsequent operator rotates the disassembly screw 11 to apply a huge axial pulling force to the movable seat 2 and the disassembly insert 17, the locking bolt 28 prevents the push rod 19 from moving, preventing the push head 21 from dislodging from the position of the two movable blocks 29 due to displacement of the push rod 19, causing the bushing 35 to fail to abut.

[0040] Reference Figures 1-7In some specific embodiments, the bottom end of the push rod 19 is provided with a mounting slot 26, one end of the push head 21 is provided with a connecting seat 20, one end of the connecting seat 20 is provided with a mounting pin 22, and the mounting pin 22 is detachably connected to the mounting slot 26.

[0041] With the above technical solution, when the push-in head 21 forces the two movable blocks 29 hinged at the bottom of the disassembly insert 17 to open outward, the movable blocks 29 need to abut against the bushing 35. At this time, the push-in head 21 needs to bear the squeezing force of the two movable blocks 29, so the push-in head 21 is easy to be damaged. Since the mounting insert 22 and the mounting slot 26 are detachably connected, it is convenient to replace the damaged push-in head 21.

[0042] Reference Figures 1-7 In some specific embodiments, a first mounting hole 23 communicating with the mounting slot 26 is provided on one side of the push rod 19, and a second mounting hole 25 is provided on one side of the mounting post 22. A mounting bolt 24 passes through the first mounting hole 23 and is threaded into the second mounting hole 25.

[0043] With the above technical solution, when the new top-entry head 21 is installed, the mounting pin 22 of the connecting seat 20 is inserted into the mounting slot 26. At this time, the mounting bolt 24 is screwed into the first mounting hole 23 and threaded into the second mounting hole 25, which facilitates fixing the position of the new top-entry head 21.

[0044] Reference Figures 6-10 In some specific embodiments, the top insertion head 21 is cone-shaped, with the protruding surface of the top insertion head 21 facing the movable block 29. The top of the movable block 29 is provided with a positioning groove 31, and the positioning grooves 31 of the two movable blocks 29 are interconnected so that the positioning grooves 31 of the two movable blocks 29 match the shape of the top insertion head 21.

[0045] With the above technical solution, when the two movable blocks 29 are in a retracted state under the magnetic force of the fixed magnet 32, the two opposing positioning grooves 31 together form a shape and size that matches the top head 21 (cone). When the operator starts to turn the top rod 19, driving the top head 21 with the conical protrusion to move downward, the top head 21 enters the top of the two movable blocks 29 to form the positioning groove 31. The top head 21 is naturally guided and positioned in the center between the two movable blocks 29. This shape matching ensures that the top head 21 will not deviate during the downward movement and can smoothly enter the predetermined position between the two movable blocks 29.

[0046] Reference Figures 1-4In some specific embodiments, the top of the base 1 is provided with a rotating groove 14, the inside of the rotating groove 14 is provided with a stabilizing bearing 13, and the other end of the disassembly screw 11 is provided with a rotating end 12, which is rotatably connected to the inner ring of the stabilizing bearing 13.

[0047] With the above technical solution, when the disassembly screw 11 rotates, the rotating end 12 at the other end of the disassembly screw 11 rotates and engages with the inner ring of the stabilizing bearing 13. The radial position of the rotating end 12 (together with the disassembly screw 11) is precisely constrained by the inner and outer rings of the stabilizing bearing 13, preventing the disassembly screw 11 from radially shifting or swaying.

[0048] Reference Figures 1-4 In some specific embodiments, the top of the base 1 is provided with multiple guide slide rods 16, and the interior of the movable seat 2 is provided with multiple guide grooves 15, with the multiple guide slide rods 16 slidingly engaging with the multiple guide grooves 15 respectively.

[0049] With the above technical solution, when the disassembly screw 11 drives the movable seat 2 to move, multiple guide slide rods 16 respectively slide and engage with multiple guide grooves 15 of the movable seat 2, thereby preventing the movable seat 2 from shifting its position and improving the stability of the movable seat 2 when it moves.

[0050] Reference Figures 1-4 In some specific embodiments, a rotating disk 36 is provided at one end of the disassembly screw 11, and a plurality of rotating push arms 37 are provided in a ring around the outer edge of the rotating disk 36.

[0051] With the above technical solution, when it is necessary to rotate the disassembly screw 11, since the outer edge of the rotating disk 36 is provided with multiple rotating push arms 37, the operator is allowed to push the disassembly screw 11 to rotate from different angles and positions. The operator can push it by grabbing the rotating push arms 37 on the outer edge of the rotating disk 36, thereby greatly improving the adaptability of operation.

[0052] Reference Figures 7-10 In some specific embodiments, a limiting protrusion 30 is provided on the other side of the movable block 29, which is used to abut against the bottom of the bushing 35.

[0053] With the above technical solution, when the top-in head 21 forces the two movable blocks 29 to rotate outward, the movable blocks 29 will abut against the bottom of the bushing 35, and the limiting protrusion 30 of the movable block 29 is located below the bushing 35, thereby preventing the movable blocks 29 from driving the bushing 35 out of the movable groove 34.

[0054] Reference Figures 1-4In some specific embodiments, the clamping part 4 includes two clamping seats 6, which are located on the top of the base 1. The two clamping seats 6 are spaced apart to form a clamping interval 5. A clamping hole 9 is provided inside the clamping seat 6. A clamping screw 7 is threaded into the clamping hole 9. One end of the clamping screw 7 is inserted into the clamping interval 5. A clamping block 8 is provided at one end of the clamping screw 7.

[0055] With the above technical solution, when it is necessary to disassemble the bushing 35, the cylinder housing 3 is placed in the clamping interval 5, and the clamping screw 7 is screwed into the clamping hole 9, so that the clamping block 8 at one end of the clamping screw 7 of the two clamping seats 6 abuts against the cylinder housing 3, thereby facilitating the clamping of the cylinder housing 3.
