Abstract
Description
Technical Field
[0001] This invention relates to the field of mechanical technology, and more specifically to a device and method for disassembling mechanical parts. Background Technology
[0002] Mechanical assembly refers to a combination of multiple components, often simply called a mechanical part. Many mechanical parts are connected by plug-in joints, where one component has a groove and another component has a protrusion that inserts into the groove, such as in some gearboxes. Prolonged use or the interference fit between the protrusion and groove can make mechanical parts difficult to disassemble. Disassembly devices can be used to disassemble these mechanical parts. The disassembly device includes a frame with a disassembly platform mounted on it. The platform has a placement station for the mechanical assembly. The frame is equipped with clamps connected by a telescopic cylinder. These clamps include a left clamp on the left side of the placement station and a right clamp on the right side. In use, the mechanical part to be disassembled is placed on the placement station, and the left and right clamps grip the left and right sides of the mechanical part, respectively. Activating the telescopic cylinder allows the mechanical part to be disassembled.
[0003] In the existing technology, the disassembly device only relies on the extension and retraction of the telescopic cylinder to disassemble the mechanical parts, which is sometimes still difficult to disassemble and has the disadvantage of being inconvenient to use. Summary of the Invention
[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a mechanical component disassembly device and method that makes it easier to disassemble mechanical components.
[0005] The technical solution of the mechanical component disassembly device of the present invention is implemented as follows: The mechanical component disassembly device includes a device frame, on which a disassembly platform is also installed. The disassembly platform has a placement station for mechanical components. A telescopic cylinder connecting clamps are installed on the device frame. The clamps include a left clamp on the left side of the placement station and a right clamp on the right side of the placement station. In use, the mechanical component to be disassembled is placed on the placement station. The left and right clamps respectively grip the left and right sides of the mechanical component. The telescopic cylinder is activated to extend and retract, allowing the mechanical component to be disassembled. The device is characterized by having multiple circumferentially evenly arranged telescopic rods around the telescopic cylinder. One end of each telescopic rod is connected to a clamp, and the other end is connected to the device frame. The telescopic rods are connected to a control device, and under the action of the control device, the multiple telescopic rods extend and retract sequentially.
[0006] Furthermore, the telescopic rod includes two telescopic rod units connected by a tube sleeve. Each telescopic rod unit has an electromagnet connected to its tube sleeve. The electromagnets are connected to a control device via wires. When the control device is activated, the two telescopic rod units move relative to each other, causing the telescopic rod to extend and retract.
[0007] Furthermore, the telescopic rod includes a left telescopic rod on the left and a right telescopic rod on the right. Under the action of the control device, the corresponding left and right telescopic rods extend and retract simultaneously, which is the first telescopic rod extension and retraction mode.
[0008] Furthermore, the telescopic rod includes a left telescopic rod on the left and a right telescopic rod on the right. Under the action of the control device, the non-corresponding left and right telescopic rods extend and retract simultaneously, which is the second telescopic rod extension and retraction mode.
[0009] Furthermore, under the control of the device, the first telescopic rod extension mode and the second telescopic mode are performed alternately.
[0010] Furthermore, the telescopic rod is also connected to the device frame via a spring.
[0011] The technical solution of the mechanical component disassembly method of the present invention is implemented as follows: The mechanical component disassembly method uses a clamp with a telescopic cylinder to clamp both sides of the mechanical component for disassembly. During the disassembly process, the telescopic cylinder extends and retracts backward; at the same time, the clamp is rotated at an angle around it in sequence to pull the clamp backward.
[0012] Furthermore, during the disassembly process, the pulling also includes pulling on both sides of the mechanical component, with the two sides being pulled relative to each other.
[0013] Furthermore, during the disassembly process, the pulling also includes pulling on both sides of the mechanical parts, and the pulling on both sides is not opposite to each other.
[0014] The beneficial effects of this invention are that such a mechanical component disassembly device and method make it easier to disassemble mechanical components. Attached Figure Description

[0021] The present invention will now be further described with reference to the accompanying drawings.
[0022] like Figure 1 As shown, the mechanical component disassembly device includes a device frame 1, on which a disassembly platform 2 is also installed. The disassembly platform has a placement station 3 for mechanical components. A clamp 4 connected to a telescopic cylinder 40 is installed on the device frame. The clamp includes a left clamp 41 on the left side of the placement station and a right clamp 42 on the right side of the placement station. In use, the mechanical component to be disassembled is placed on the placement station. The left and right clamps respectively grip the left and right sides of the mechanical component. The telescopic cylinder is activated to extend and retract, allowing the mechanical component to be disassembled. Its characteristic is that there are multiple telescopic rods 5 evenly arranged in a circular shape around the telescopic cylinder. One end of each telescopic rod is connected to a clamp, and the other end is connected to the device frame. The telescopic rods are connected to a control device 6. Under the action of the control device, the multiple telescopic rods extend and retract sequentially.
[0023] The mechanical component disassembly device of the present invention, with the above-mentioned arrangement, enables pulling at certain angles around the side of the mechanical component during the disassembly process, for example, at intervals of 45° or 60°. Figure 2 In the sequence, the telescopic cylinders at positions D1, D2, D3, D4, D5, and D6 extend and retract. This allows for a more effective disassembly.
[0024] The aforementioned clamp only needs to be able to clamp the side of the mechanical part. For example, it can be a buckle that clamps the mechanical part, or an ordinary clamp, or a caliper, etc., which are components in the prior art.
[0025] The control device can also be a PLC or a programmable controller.
[0026] In one technical solution, the telescopic rod is connected to an electrical component, such as an electromagnet or a motor, or any electrical component capable of controlling the extension and retraction of the telescopic rod. The electrical component is connected to a power supply line. The control device has a control panel 61 with multiple evenly distributed fixed terminals 62 around it. These fixed terminals are connected to the electrical component via power supply lines, and each fixed terminal is connected to the power supply line of its respective telescopic rod. The control panel also has a rotating terminal 63 driven by a motor. During rotation, the rotating terminal sequentially contacts different fixed terminals, opening the electrical circuit of the telescopic rod and causing it to extend and retract.
[0027] In one embodiment, such as Figure 3 As shown, the telescopic rod includes two telescopic rod units 51, which are connected by a sleeve 53. Each sleeve of the telescopic rod unit is connected to an electromagnet 52. The electromagnets are connected to a control device via wires. When the control device is activated, the two telescopic rod units move relative to each other, causing the telescopic rod to extend and retract.
[0028] In another embodiment, such as Figure 4 As shown, the telescopic rod includes a sleeve 53 and a telescopic support rod 54 that can be slidably installed in the sleeve. A motor 55 is installed on the side of the sleeve, and the motor is connected to a grooved wheel 56. The grooved wheel has grooves 561 around its circumference that are not on a single plane. The telescopic support rod has a guide protrusion 541, which is located in the groove. When the motor is turned on, the grooved wheel rotates, and the groove drives the guide protrusion to move left and right, thereby driving the telescopic support rod to move left and right. The left and right movement of the telescopic support rod here is the telescopic extension and retraction of the telescopic rod.
[0029] Furthermore, the telescopic rod includes a left telescopic rod 57 on the left and a right telescopic rod 58 on the right. Under the action of the control device, the corresponding left and right telescopic rods extend and retract simultaneously, which is the first telescopic rod extension and retraction mode.
[0030] The simultaneous extension and retraction of the corresponding left and right telescopic rods means that the line connecting these two telescopic rods is parallel to the center line L of the left and right locking pieces 41 and 41.
[0031] Right now Figure 1 In the diagram, a1, a2, a3, and a4 are all telescopic rods. When telescopic rods a1 and a2 extend and retract simultaneously, and when telescopic rods a3 and a4 extend and retract simultaneously...
[0032] This invention allows for better disassembly of some mechanical components.
[0033] Furthermore, the telescopic rod includes a left telescopic rod 57 on the left and a right telescopic rod 58 on the right. Under the action of the control device, the non-corresponding left and right telescopic rods extend and retract simultaneously. This is the second telescopic rod extension and retraction mode.
[0034] The simultaneous extension and retraction of the non-corresponding left and right telescopic poles means that the pulling directions of these two telescopic poles are different; that is, when the left telescopic pole extends or retracts, its corresponding right telescopic pole does not extend or retract; and when the right telescopic pole extends or retracts, its corresponding left telescopic pole does not extend or retract.
[0035] Right now Figure 1 In the diagram, a1, a2, a3, and a4 are all telescopic rods. When telescopic rods a1 and a4 extend and retract simultaneously, and when telescopic rods a3 and a2 extend and retract simultaneously...
[0036] The best approach is to extend and retract two diagonally opposite telescopic poles simultaneously. For example, when the top left telescopic pole extends, the bottom right telescopic pole extends at the same time; or when the front left telescopic pole extends, the rear right telescopic pole extends at the same time.
[0037] This invention allows for better disassembly of some mechanical components.
[0038] Furthermore, under the control of the device, the first telescopic rod extension mode and the second telescopic mode are performed alternately.
[0039] Furthermore, the telescopic rod is also connected to the device frame via spring 59.
[0040] The technical solution of the mechanical component disassembly method of the present invention is implemented as follows: The mechanical component disassembly method uses a clamp with a telescopic cylinder to clamp both sides of the mechanical component for disassembly. During the disassembly process, the telescopic cylinder extends and retracts backward; at the same time, the clamp is rotated at an angle around it in sequence to pull the clamp backward, so as to achieve the effect of quick or complete disassembly.
[0041] Furthermore, during the disassembly process, the pulling also includes pulling on both sides of the mechanical components, with the two sides being pulled relative to each other; this is the first telescopic rod telescopic mode.
[0042] Furthermore, during the disassembly process, the pulling also includes pulling on both sides of the mechanical parts. The pulling on both sides is not opposite to each other; this is the second telescopic rod telescopic mode.
[0043] Furthermore, under the control of the device, the first telescopic rod extension mode and the second telescopic mode are performed alternately.
[0044] It should be noted that the embodiments and beneficial effects of the above-mentioned mechanical component disassembly device and mechanical component disassembly method can be explained or described with each other.
[0045] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.
