Abstract

The present invention discloses a disassembly device, which includes a rotating shaft, a connecting piece, a fixing plate, a rotating plate, a screw rod and a sleeve. During use, the connecting piece is used to connect the bolt and the rotating shaft. The operator rotates the rotating plate, and the first end of the rotating plate drives the second end of the rotating shaft to rotate. The rotating shaft drives the bolt of the connecting piece and the booster cylinder to rotate, thereby loosening the bolt of the booster cylinder and improving the disassembly efficiency of the booster cylinder. At the same time, the two ends of the fixing plate and the intersection point of the screw rod and the rotating plate form a triangle. When the rotating plate rotates, the position of the intersection point of the screw rod and the rotating plate changes continuously, thereby realizing the movement of the rotating plate along a preset trajectory and realizing the limit of the rotating plate, further improving the disassembly efficiency of the booster cylinder.

Description

Technical Field

[0001] This invention relates to the field of power cylinder disassembly technology, and more particularly to a disassembly device. Background Technology

[0002] The pressure cylinder of a vulcanizing machine is a mechanism that applies force to the mold after it closes. The pressure cylinder provides sufficient power to ensure the mold has sufficient closing force during the vulcanization process, preventing deformation and flash in the vulcanized tire. The model and number of pressure cylinders vary depending on the tire size. In existing technology, 3, 4, or 6 pressure cylinders are typically evenly distributed around the center of the mold. Each pressure cylinder experiences significant force and has shape and position tolerance requirements. Therefore, during installation, sealant must be applied to the bolts, anti-loosening washers must be added, and anti-loosening markings must be applied to the bolts after installation to ensure each bolt is tightened, thus guaranteeing the tightness of the pressure cylinder. However, if the pressure cylinder leaks oil, or if the vulcanizing machine reaches a certain age and requires maintenance, disassembling the pressure cylinder bolts becomes difficult. This is because each pressure cylinder has many bolts (eight or more); the maintenance space is limited, making it difficult to use a bolt wrench; and the bolts require significant tightening and loosening force. Therefore, it is impossible to effectively disassemble the booster cylinder manually.

[0003] Therefore, how to improve the disassembly efficiency of the booster cylinder is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a disassembly device to improve the disassembly efficiency of the booster cylinder;

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A disassembly device for removing bolts from a booster cylinder includes a rotating shaft, a connecting piece, a fixed plate, a rotating plate, a lead screw, and a sleeve, wherein:

[0007] The connector is arranged at the first end of the rotating shaft and connected to the bolt, and is used to drive the bolt to rotate;

[0008] The first end of the rotating plate is fixedly connected to the second end of the rotating shaft, and its second end is rotatably connected to the first end of the lead screw.

[0009] The sleeve is fitted around the outside of the rotating shaft, and the first end of the fixed plate is rotatably connected to the second end of the sleeve, and its second end is rotatably connected to the second end of the lead screw.

[0010] The disassembly device further includes a positioning plate and a positioning bolt. The positioning plate is fixedly connected to the sleeve, and the positioning plate includes multiple through holes. The fixing plate has a positioning hole. The positioning bolt passes through the through holes and the positioning hole to connect the fixing plate and the positioning plate.

[0011] The disassembly device further includes a fixed shaft, a first through hole at the first end of the fixed shaft, a lead screw passing through the first through hole and fixedly connected to the first end of the fixed shaft, and the fixed shaft sleeved on the second end of the lead screw, and the second end of the fixed shaft rotatably connected to the second end of the fixed plate;

[0012] The disassembly device further includes a sliding shaft with a second through hole in its radial direction. The lead screw passes through the second through hole and is slidably connected to the sliding shaft. The second end of the rotating plate is sleeved on the outside of the sliding shaft, and the sliding shaft is rotatably connected to the second end of the rotating plate.

[0013] Optionally, the disassembly device further includes a clamping arm connected to the first end of the sleeve, and the clamping arm is used to clamp the force-applying cylinder.

[0014] Optionally, the disassembly device further includes an internal hex bolt head, the first end of which is threadedly connected to the bolt, the first end of the connector is provided with a boss, the boss is inserted into the second end of the internal hex bolt head, and the boss is used to drive the internal hex bolt head to rotate, the second end of the connector is provided with a connecting hole, and the connecting hole is inserted into the first end of the rotating shaft.

[0015] Optionally, the disassembly device further includes a support plate and a support shaft. The first end of the support plate is sleeved outside the second end of the rotating shaft, and the first end of the support plate is rotatably connected to the second end of the rotating shaft. The second end of the support plate is fixedly connected to the second end of the support shaft, and the first end of the support shaft is connected to the bottom of the booster cylinder.

[0016] Optionally, the first end of the rotating shaft has four protrusions, and the connecting hole is an octagonal hole.

[0017] Optionally, the clamping arm is in the shape of an arc.

[0018] Optionally, the number of positioning holes is two or more.

[0019] The disassembly device provided by this invention uses a connector to connect bolts and a rotating shaft. The operator rotates a rotating plate, causing the first end of the rotating plate to rotate the second end of the rotating shaft. The rotating shaft then rotates the bolts of the connector and the force-applying cylinder, thereby loosening the bolts and improving the disassembly efficiency of the force-applying cylinder. Simultaneously, the two ends of the fixed plate and the intersection of the lead screw and the rotating plate form a triangle. As the rotating plate rotates, the position of the intersection of the lead screw and the rotating plate continuously changes, allowing the rotating plate to move along a preset trajectory. This limits the movement of the rotating plate and further improves the disassembly efficiency of the force-applying cylinder. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without novelty are within the scope of protection of the present invention.

[0040] In the description of this invention, it should be understood that the terms "upper," "lower," "top surface," "bottom surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] like Figures 1-9As shown, the disassembly device disclosed in this invention is used to disassemble the bolt 901 of the force-adjusting cylinder 900. It includes a rotating shaft 100, a connecting member 200, a fixing plate 300, a rotating plate 400, a lead screw 500, and a sleeve 600. The connecting member 200 is arranged at the first end of the rotating shaft 100 and connected to the bolt 901, driving the bolt 901 to rotate. The first end of the rotating plate 400 is fixedly connected to the second end of the rotating shaft 100, and its second end is rotatably connected to the first end of the lead screw 500. The sleeve 600 is sleeved on the outside of the rotating shaft 100. The first end of the fixing plate 300 is connected to the second end of the sleeve 600, and its second end is rotatably connected to the second end of the lead screw 500. Specifically, in use, the operator rotates the first end of the rotating plate 400, which in turn rotates the rotating shaft 100. The rotating shaft 100 then rotates the connecting member 200, which in turn rotates the bolt 901, thereby loosening the bolt 901. It should be noted that the reason why bolts in the existing technology are not easy to disassemble is that the connection is very tight, and manual disassembly is time-consuming and labor-intensive. By using a disassembly device to disassemble bolt 901, bolt 901 can be loosened mechanically, and then bolt 901 can be removed by gently turning it manually, thereby greatly improving the disassembly efficiency of bolt 901.

[0042] In use, the connector 200 connects the bolt 901 and the rotating shaft 100. The operator rotates the rotating plate 400, and the first end of the rotating plate 400 drives the second end of the rotating shaft 100 to rotate. The rotating shaft 100 drives the bolt 901 of the connector 200 and the force-applying cylinder 900 to rotate, thereby loosening the bolt 901 of the force-applying cylinder 900 and improving the disassembly efficiency of the force-applying cylinder 900. At the same time, the two ends of the fixed plate 300 and the intersection of the lead screw 500 and the rotating plate 400 form a triangle. When the rotating plate 400 rotates, the position of the intersection of the lead screw 500 and the rotating plate 400 changes continuously, thereby enabling the rotating plate 400 to move along a preset trajectory and achieving the limitation of the rotating plate 400, thus further improving the disassembly efficiency of the force-applying cylinder 900. To optimize the above technical solution, the disassembly device further includes a positioning plate 700 and positioning bolts 701. The positioning plate 700 is fixedly connected to the sleeve 600, and the positioning plate 700 includes multiple through holes 702. The fixing plate 300 has positioning holes, and the positioning bolts 701 pass through the through holes 702 and the positioning holes to connect the fixing plate 300 and the positioning plate 700. Specifically, the positioning plate 700 and the positioning bolts 701 are used to adjust the initial position of the fixing plate 300. The positioning plate 700 is fan-shaped and extends along the direction close to the force-applying cylinder 900 with the rotating shaft 100 as the center, and has through holes 702 arranged at different positions from the rotating shaft 100. In use, the operator connects the disassembly device to the booster cylinder 900. Because the positioning plate 700 is fixedly connected to the sleeve 600 and the fixing plate 300 is rotatably connected to the sleeve 600, the initial position of the fixing plate 300, i.e. the initial position of the lead screw 500, can be adjusted by first passing the positioning bolt 701 through the through hole 702 at different positions and then through the positioning hole on the fixing plate 300. This further limits the movement trajectory of the rotating plate 400, thereby improving the disassembly efficiency of the booster cylinder 900.

[0043] It should be noted that when the disassembly device is used, the vertical distance between the rotating plate 400 and the first end of the lead screw 500 is determined, the vertical distance between the second end of the lead screw 500 and the second end of the fixed plate 300 is determined, and the fixed plate 300 is fixedly connected to the positioning plate 700 and the positioning plate 700 is fixedly connected to the sleeve 600. Therefore, the first end of the fixed plate 300 is arranged at the preset position of the sleeve 600, the positioning plate 700 fixes the position of the sleeve 600, and the rotating shaft 100 can rotate relative to the sleeve 600 inside the sleeve 600.

[0044] To optimize the above technical solution, the disassembly device further includes a clamping arm 601, which is connected to the first end of the sleeve 600 and is used to clamp the force-applying cylinder 900. Specifically, the clamping arm 601 is arc-shaped and fixedly connected to the sleeve 600. The diameter corresponding to the arc of the clamping arm 601 is equal to or slightly larger than the diameter of the force-applying cylinder 900, so as to tightly hold the force-applying cylinder 900 and make it difficult for it to move, thereby improving the disassembly efficiency of the disassembly device. In some embodiments of the present invention, the clamping arm 601 is semi-circular or slightly curved. In this case, when assembling the disassembly device with the force-applying cylinder 900, it is only necessary to clamp the clamping arm 601 horizontally to the outer wall of the force-applying cylinder 900. This arrangement makes the disassembly device easy to install and improves the efficiency of the disassembly device.

[0045] In other embodiments of the present invention, the clamping arm 601 is in a superior arc shape. In this case, when assembling the disassembly device with the force-applying cylinder 900, the operator needs to pass the clamping arm 601 through the force-applying cylinder 900 from bottom to top to ensure that the clamping arm 601 and the force-applying cylinder 900 are in close contact. This arrangement increases the contact area between the clamping arm 601 and the force-applying cylinder 900, and the clamping arm 601 forms a closing clamping force on the force-applying cylinder 900, thereby improving the clamping effect on the force-applying cylinder 900, that is, improving the stability of the disassembly device. Therefore, the present invention preferably uses a superior arc shape for the clamping arm 601.

[0046] To optimize the above technical solution, the disassembly device further includes an internal hexagonal bolt head 201. The first end of the internal hexagonal bolt head 201 is threadedly connected to the bolt 901. A boss 202 is provided at the first end of the connector 200, and the boss 202 is inserted into the second end of the internal hexagonal bolt head 201. The boss 202 is used to drive the internal hexagonal bolt head 201 to rotate. A connecting hole 203 is provided at the second end of the connector 200, and the connecting hole 203 is inserted into the first end of the rotating shaft 100. Specifically, the boss 202 is a hexagonal boss to fit the internal hexagonal bolt head 201. In use, the first end of the hex bolt head 201 is threaded to the bolt 901, and the boss 202 is inserted into the second end of the hex bolt head 201 to connect the connector 200 and the bolt 901. The first end of the rotating shaft 100 is inserted into the connecting hole 203 to connect the rotating shaft 100 and the connector 200. The operator rotates the rotating plate 400, which drives the rotating shaft 100 to rotate. The rotating shaft 100 drives the bolt 901 to rotate, thereby loosening the bolt 901 and improving the disassembly efficiency of the bolt 901 of the force cylinder 900.

[0047] Furthermore, by changing the shape of the boss 202 and the connecting hole 203, different forms of snap-fit ​​can be achieved for the connector 200.

[0048] Preferably, the first end of the rotating shaft 100 has four protruding corners, and the connecting hole 203 is an octagonal hole. This arrangement allows the operator to rotate the rotating shaft 100 to different angles and insert it into the connecting hole 203, thereby changing the initial position of the rotating shaft 100.

[0049] To optimize the above technical solution, the disassembly device further includes a fixed shaft 501. The first end of the fixed shaft 501 has a first through hole. The lead screw 500 passes through the first through hole and is fixedly connected to the first end of the fixed shaft 501. The fixed shaft 501 is sleeved on the second end of the lead screw 500. The second end of the fixed shaft 501 is rotatably connected to the second end of the fixed plate 300. Specifically, the second end of the fixed plate 300 has a hole for fixing the fixed shaft 501. Bolts can be passed through this hole to rotatably connect the second end of the fixed shaft 501 to the second end of the fixed plate 300. Specifically, bolts for fixing are arranged on both sides of the first through hole to ensure the connection stability between the fixed shaft 501 and the second end of the lead screw 500. This arrangement allows the fixed plate 300 and the second end of the lead screw 500 to be rotatably connected, so that the intersection of the lead screw 500 and the rotating plate 400 draws an arc with the fixed plate 300 as the diameter, i.e., using this arc as the movement trajectory, further improving the stability of the disassembly device and thus increasing the disassembly efficiency of the bolt 901.

[0050] To optimize the above technical solution, the disassembly device further includes a sliding shaft 502. The sliding shaft 502 has a second through hole in its radial direction. A lead screw 500 passes through the second through hole and is slidably connected to the sliding shaft 502. The second end of a rotating plate 400 is sleeved on the outside of the sliding shaft 502, and the sliding shaft 502 and the second end of the rotating plate 400 are rotatably connected. In use, the operator rotates the second end of the rotating plate 400, causing the sliding shaft 502 to move. The sliding shaft 502 rotates relative to the rotating plate 400, while the first end of the lead screw 500 slides inside the second through hole. This arrangement causes a preset change in the angle between the lead screw 500 and the rotating plate 400, thereby limiting the rotation of the rotating plate 400 and preventing it from rotating excessively. This further improves the disassembly efficiency of the disassembly device for the force-applying cylinder 900.

[0051] To optimize the above technical solution, the disassembly device also includes a support plate 800 and a support shaft 801. The first end of the support plate 800 is sleeved on the outside of the second end of the rotating shaft 100, and the first end of the support plate 800 is rotatably connected to the second end of the rotating shaft 100. The second end of the support plate 800 is fixedly connected to the second end of the support shaft 801, and the first end of the support shaft 801 is connected to the bottom of the booster cylinder 900. Specifically, when the rotating shaft 100 rotates, it rotates relative to the first end of the support plate 800, while the support plate 800 and the support shaft 801 remain stationary. The support shaft 801 supports the booster cylinder 900, and the support plate 800 supports the rotating shaft 100 and the support shaft 801. Bolts for fixing are arranged on both sides of the second end of the support plate 800 to secure the support plate 800 and the support shaft 801 together. The first end of the support shaft 801 is threaded, and the bottom of the booster cylinder 900 has a threaded hole. The operator mates the thread with the threaded hole to install the support shaft 801. By arranging the support plate 800 and the support shaft 801, the booster cylinder 900 and the disassembly device can be supported, thereby improving the stability of the disassembly device during use and further improving the efficiency of disassembling the bolts 901 of the booster cylinder 900.

[0052] To optimize the above technical solution, the number of positioning holes is two or more. Specifically, the more positioning holes there are, the more stable the connection between the fixing plate 300 and the positioning plate 700. Operators can change the number of positioning holes according to usage needs. Preferably, the number of positioning holes in this invention is two.

[0053] The advantages of this invention are:

[0054] (1) Improved the disassembly efficiency of the booster cylinder;

[0055] (2) High stability and high security;
