[0043] Refer to Figures 1 to 12 The shown fitting disassembly device, the device includes a fixing bracket 1, two clamping members 2, two driving components, a slide bar 6, an impact block 7 and a sliding hammer 8, wherein:

[0044] A through groove is formed on the fixing bracket 1, and the through groove penetrates through the front and rear ends of the fixing bracket 1 (front and rear refer to Figure 1In the shown direction, two clamping members 2 are arranged oppositely. Both clamping members 2 are located in the through groove of the fixed frame 1. The two clamping members 2 are used to clamp the key 9. The driving components correspond to the clamping members 2 one by one. The driving component includes a driving rod 3. One end of the driving rod 3 penetrates through the fixed frame 1. One end of the driving rod 3 passes through the fixed frame 1 into the through groove and is connected to the clamping member 2. The other end of the driving rod 3 extends outside the through groove. At least one driving rod 3 is movably arranged on the fixed frame 1. The driving rod 3 is used to drive the clamping member 2 to move towards or away from the other clamping member 2. Among them, the two driving rods 3 respectively pass through the left and right ends of the fixed frame. One end of the sliding rod 6 is connected to the fixed frame 1. The extending direction of the sliding rod 6 is perpendicular to the extending direction of the driving rod 3 (if the sliding rod 6 extends along the Y-axis and the driving rod 3 extends along the X-axis). The impact block 7 is connected to the other end of the sliding rod 6. The sliding hammer 8 is slidably arranged on the sliding rod 6.

[0045] The detachable objects of the fitting disassembly device in this example are the key 9, pins, etc.

[0046] The specific implementation manner of the fitting disassembly device in this example for disassembling the fitting is as follows: First, move the clamping member 2 close to the fitting to be disassembled. Operate the driving rod 3 to drive the clamping member 2 to move towards or away from the other clamping member 2 until the two clamping members 2 clamp the fitting to be disassembled. Then, operate the sliding hammer 8 to move along the sliding rod 6 to strike the impact block 7. An impact force is generated between the sliding hammer 8 and the impact block 7. The force is transmitted to the fitting to be disassembled through the sliding rod 6. After the fitting receives the outward impact force, it starts to withdraw until it is completely disassembled.

[0047] See Figure 12 , the fixed frame 1 includes a first plate body 101 and two second plate bodies 102. The opposite ends of the first plate body 101 are respectively connected to the two second plate bodies 102. The first plate body 101 is perpendicular to the second plate bodies 102. A U-shaped through groove is formed between the first plate body 101 and the two second plate bodies 102. One end of the sliding rod 6 is connected to the first plate body 101. At least one driving rod 3 is movably arranged on the second plate body 102. The first plate body 101 and the second plate bodies 102 are both strip-shaped. The end surface of the first plate body 101 connected to one end of the sliding rod 6 is a horizontal plane.

[0048] In some embodiments, the end surface 1022 of the second plate body 102 away from the first plate body 101 is inclined. This end surface extends obliquely outward away from the other second plate body 102. This inclined end surface can be recessed in an arc shape away from the other clamping member 2. The fitting to be disassembled is arranged on the transmission shaft 10. An installation groove is provided on the transmission shaft 10 where the fitting is located to accommodate the fitting to be disassembled. The end surface of the second plate body 102 away from the first plate body 101 is inclined, which can avoid collision with the transmission shaft 10 where the fitting is located and prevent damage to the transmission shaft 10 during the disassembly process.

[0049] In a preferred embodiment, the driving assembly further includes a first nut 4 and a second nut 5. An external thread is provided on the outer side of the driving rod 3 (the driving rod 3 can be a screw rod). Both the first nut 4 and the second nut 5 are arranged outside the driving rod 3. The first nut 4 is located in the through groove of the fixing frame 1, and the second nut 5 is away from the through groove of the fixing frame 1 (located outside the through groove). The driving rod 3 is movably arranged on the second plate body 102 of the fixing frame 1. The first nut 4 and the second nut 5 are respectively located on opposite sides of the second plate body 102, and the first nut 4 and the second nut 5 are used to limit the movement of the driving rod 3. When the driving rod 3 moves to a proper position, the positions of the driving rod 3 are fixed by tightening the first nut 4 and the second nut 5 to better clamp the clamping member 2, and then the sliding hammer 8 is operated to unload the fitting.

[0050] In this example, the opening 1021 on the second plate body 102 of the fixing frame 1 through which the driving rod 3 passes is elongated. The extending direction of the opening 1021 is perpendicular to the extending direction of the driving rod 3, and the extending direction of the opening 1021 is consistent with the extending direction of the second plate body 102. The setting of the opening facilitates the adjustment of the clamping member 2 by the driving rod 3 in the direction perpendicular to the driving rod 3. The positions can be set according to the size of the fitting to be disassembled to flexibly move the driving rod 3 and the clamping member 2, which can better disassemble the fitting to be disassembled, with more flexible and faster operation, without damaging the fitting to be disassembled and the shaft on which the fitting to be disassembled is located.

[0051] See Figure 10 , a groove 401 recessed towards the center is provided on the outer peripheral wall of the first nut 4, which is convenient for inserting a flat-blade (similar to a minus sign) screwdriver into the groove 401 to tighten and loosen the first nut 4, facilitating the operation.

[0052] The second nut 5 includes a sleeve 501 and an operating rod 502. An internal thread matching the driving rod 3 is provided inside the sleeve 501. The operating rod 502 penetrates through the sleeve 501, and the extending direction of the operating rod 502 is perpendicular to the axial direction of the sleeve 501. For the second nut 5 with this structure, the second nut 5 can be manually tightened and loosened, and the operation is convenient and fast.

[0053] In some embodiments, see Figures 9 - 10 , a limiting boss 11 is provided at one end of the driving rod 3 connected to the clamping member 2. The limiting boss 11 is arranged around the outer periphery of the driving rod 3. The limiting boss 11 is located in the through groove of the fixing frame 1. The cross-section of the limiting boss 11 is circular, and the diameter of the limiting boss 11 is larger than the diameter of the driving rod 3. The setting of the limiting boss 11 is used to limit the clamping member 2 and the fixing frame 1 from fitting together, improving the service life of the overall device.

[0054] In some embodiments, the fitting to be disassembled is a key 9. The surface of the key 9 in contact with the clamping member 2 is a plane. One end of the clamping member 2 facing another clamping member 2 (i.e., the end of the clamping member 2 in contact with the key 9) is a tip, and the clamping member 2 is in line contact with the fitting to be disassembled.

[0055] See Figures 10 - 11 , the clamping member 2 has an upper surface 201, a lower surface 202, a front surface, a rear surface 203, and side surfaces 204. The front surface and the rear surface 203 are oppositely and parallelly arranged. The upper surface 201 is perpendicular to the side surfaces 204. The front surface is perpendicular to both the upper surface 201 and the side surfaces 204. The rear surface 203 is perpendicular to both the upper surface 201 and the side surfaces 204. The lower surface 202 is connected to the upper surface 201, the front surface, the rear surface 203, and the side surfaces 204. The lower surface 202 faces the axis where the fitting to be disassembled is located. One side of the upper surface 201 and one side of the lower surface 202 are connected and share an edge to form a tip. An acute angle is formed between the upper surface 201 and the lower surface 202. An acute angle is formed between the side surface 204 and the lower surface 202. The driving rod 3 is connected to the side surface 204 of the clamping member 2. In the state of clamping the fitting to be disassembled, the upper surface 201 is horizontally set as a plane, the side surface 204 is a vertical plane, and both the front surface and the rear surface 203 are vertically arranged.

[0056] Preferably, the lower surface 202 of the clamping member 2 is an arc-shaped surface that slopes downward and away from the other clamping member 2. In the state of clamping the fitting to be disassembled, the clamping member 2 will not touch the transmission shaft 10 where the fitting to be disassembled is located, which plays a role in protecting the transmission shaft 10.

[0057] In another embodiment, the end surface of the clamping member 2 facing the other clamping member 2 (i.e., the end where the clamping member 2 contacts the fitting to be disassembled) is a plane, and the clamping member 2 and the fitting to be disassembled are in surface contact; or the end surface of the clamping member 2 facing the other clamping member 2 (i.e., the end where the clamping member 2 contacts the fitting to be disassembled) is an arc-shaped surface.

[0058] In this example, both the sliding hammer 8 and the impact block 7 are cylindrical.

[0059] The advantages of the fitting disassembly device in this example are as follows:

[0060] 1. By setting two clamping members to clamp the fitting to be disassembled, driving the clamping member to move by the driving rod to clamp the fitting, operating the sliding hammer to move along the sliding rod to impact the impact block, the sliding hammer and the impact block generate an impact force, and the force is transmitted to the fitting through the sliding rod. After the fitting receives an outward impact force, it starts to withdraw until it is completely disassembled, and the operation is simple and fast;

[0061] 2. The device has a compact structure, is time-saving and labor-saving in disassembling the fitting, does not damage the fitting, has high safety, and high efficiency.
