Description

Technical Field

[0001] This invention relates to the field of equipment for disassembling parts on shafts, and in particular to a device for disassembling flange parts on shafts. Background Technology

[0002] When installing parts on a shaft, many are installed using pressing or heating methods. If these parts need to be disassembled after installation, tools such as pullers are required. Ordinary pullers use their pull feet to hook the end face of the part on the shaft, and then feed the top shaft end through the lead screw to push the part out. This method requires manual rotation of the lead screw with a wrench, which is not only laborious and requires a certain level of skill from the operator, but also carries the risk of the lead screw stripping when the friction between the part on the shaft and the shaft is high.

[0003] To address the problems of conventional pullers, existing hydraulic pullers can provide sufficient force to disassemble parts on the shaft. However, hydraulic pullers still use pull feet to hook the end face of the parts on the shaft, which is time-consuming. Furthermore, the extension and retraction time of the hydraulic rod is slow, and the extension and retraction length range of the hydraulic rod is fixed. If the distance between the parts on the shaft and the shaft end is too long or too short, the hydraulic puller cannot reach the shaft end within the extension and retraction range.

[0033] Example 1

[0034] Reference Figures 1-9 This is the first embodiment of the present invention. This embodiment provides a disassembly device for a flange part on a shaft, specifically including a disassembly mechanism 100, which includes a disassembly disc 101, a hydraulic column 102 disposed on the side wall of the disassembly disc 101, and disassembly columns 103 symmetrically fixed on both sides of the hydraulic column 102; and a quick fixing mechanism 200, which includes a first limiting component 201 disposed in the disassembly column 103, a second limiting component 202 disposed below the first limiting component 201, and a ratchet assembly 203 disposed above the first limiting component 201.

[0035] Furthermore, the disassembly column 103 is provided with a first sliding groove W-1, a second sliding groove W-2 located in the middle of the first sliding groove W-1, a third sliding groove W-3 located on the side wall of the first sliding groove W-1, and a retaining groove W-4 located at the connection between the first sliding groove W-1 and the third sliding groove W-3; the first limiting assembly 201 includes a first sliding seat 201a slidably disposed in the second sliding groove W-2, a second sliding seat 201b fixed to the lower part of the first sliding seat 201a, and a retaining groove fixed to the lower part of the second sliding seat 201b. The first limiting block 201c and the first spring 201d are respectively fixed at the bottom of the first limiting block 201c and the bottom of the first sliding groove W-1; the end of the first limiting block 201c extends out of the third sliding groove W-3; the width of the third sliding groove W-3 is smaller than the width of the first sliding groove W-1, and the width of the first sliding groove W-1 is smaller than the width of the second sliding groove W-2; the slot W-4 located at the connection between the first sliding groove W-1 and the third sliding groove W-3 is "L" shaped, and the groove depth of the part in the third sliding groove W-3 is deeper.

[0036] Preferably, the second sliding seat 201b has a third sliding hole K-3; the second limiting component 202 includes a third slider 202a slidably disposed in the third sliding hole K-3, a fourth spring 202b with its two ends respectively contacting the third slider 202a and the third sliding hole K-3, and a pressure member 202c and a locking member 202d slidably disposed in the third slider 202a; the top edge of the third slider 202a extending out of the third sliding hole K-3 is rounded.

[0037] In this embodiment, the first limiting component 201 and the second limiting component 202 cooperate to quickly fix the flange part on the shaft onto the quick fixing mechanism 200, and the ratchet assembly 203 makes the end of the shaft fixing the flange part quickly approach the end of the hydraulic column 102.

[0038] Example 2

[0039] Reference Figures 1-12 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the first sliding seat 201a has a first sliding hole K-1 and a second sliding hole K-2 connected to the lower part of the first sliding hole K-1; the first sliding seat 201a has a first slider 201a-1 slidably disposed in the first sliding hole K-1, a second spring 201a-2 with both ends in contact with the first sliding hole K-1 and the first slider 201a-1 respectively, a second slider 201a-3 slidably disposed in the second sliding hole K-2, and a third spring 201a-4 with both ends in contact with the second sliding hole K-2 and the second slider 201a-3 respectively; the top edge of the first slider 201a-1 extending out of the first sliding hole K-1 is chamfered, and the top edge of the second slider 201a-3 facing the first slider 201a-1 is rounded.

[0041] It should be noted that after the first slider 201a-1 is pressed into the first sliding hole K-1, the top of the second slider 201a-3 will be pressed into the second sliding hole K-2, so that the bottom of the second slider 201a-3 extends out of the bottom of the second sliding hole K-2.

[0042] Furthermore, the third slider 202a has a pressing cavity K-4 located on its upper surface, a connecting block cavity K-5 connected to the side wall of the pressing cavity K-4, and a locking cavity K-6 connected to the side wall of the connecting block cavity K-5; the top of the pressing cavity K-4 is connected to the bottom of the third sliding hole K-3, and the locking cavity K-6 is connected to the locking groove W-4; the pressing member 202c includes a pressing block 202c-1 slidably disposed in the pressing cavity K-4, a connecting block 202c-2 slidably disposed in the connecting block cavity K-5, and a fifth spring 202c-3 whose two ends respectively contact the connecting block 202c-2 and the connecting block cavity K-5; the top edge of the connecting block 202c-2 extending into the pressing cavity K-4 is rounded.

[0043] It should be noted that after the bottom of the second slider 201a-3 extends out of the bottom of the second sliding hole K-2, the bottom of the second slider 201a-3 will press the pressure block 202c-1, causing the pressure block 202c-1 to slide downward. The pressure block 202c-1 will then press the connecting block 202c-2, causing the connecting block 202c-2 to overcome the elastic force of the fifth spring 202c-3 and slide into the locking cavity K-6.

[0044] Furthermore, the locking component 202d includes a locking block 202d-1 symmetrically slidably disposed in the locking block cavity K-6, and a sixth spring 202d-2 disposed in the locking block cavity K-6; ​​one end of the locking block 202d-1 extends into the locking groove W-4, and the bottom edge of the locking block 202d-1 extending into the locking groove W-4 is rounded; the disassembly column 103 is also provided with a ratchet groove W-5 communicating with the upper section of the second sliding groove W-2, and a pawl groove W-6 communicating with the upper part of the ratchet groove W-5.

[0045] It should be noted that after the connecting block 202c-2 slides into the card block cavity K-6, the two ends of the connecting block 202c-2 will block between the two card blocks 202d-1, preventing the card blocks 202d-1 from retracting into the card block cavity K-6; ​​the length of the card slot W-4 is greater than the length of the card block 202d-1.

[0046] Preferably, the ratchet assembly 203 includes a first ratchet 203a fixed to the upper part of the first sliding seat 201a and slidably disposed in the second sliding groove W-2, a second ratchet 203b slidably disposed in the ratchet groove W-5, a pry block 203c fixed to the upper part of the second ratchet 203b and slidably disposed in the pry groove W-6, and a seventh spring 203d whose two ends respectively contact the second ratchet 203b and the ratchet groove W-5; the ratchet teeth on the first ratchet 203a and the second ratchet 203b are in contact with each other.

[0047] It should be noted that under the elastic force of the seventh spring 203d, the ratchet on the second ratchet plate 203b will stick to the ratchet on the first ratchet plate 203a. Under this condition, the first ratchet plate 203a cannot rise after it descends.

[0048] In this embodiment, when it is necessary to disassemble the flange part on the shaft, the operator only needs to align the disassembly column 103 with the hole on the flange part and insert it. During the insertion process, the hole wall on the flange part will first squeeze the first slider 201a-1. When squeezing the first slider 201a-1, since the locking block 202d-1 is stuck in the groove W-4 at a deeper depth than the third sliding groove W-3, the groove depth here is longer than the rounded length of the locking block 202d-1. Therefore, the locking block 202d-1 cannot slide out of the groove W-4. Under the limitation of the locking block 202d-1 and the groove W-4, the process of inserting the flange part cannot make the quick fixing mechanism 200 slide down as a whole.

[0049] It should be noted that during the continued insertion of the flange part, the wall of the flange part's hole will simultaneously press the first slider 201a-1 and the third slider 202a. After the first slider 201a-1 is pressed into the first sliding hole K-1, the top of the second slider 201a-3 will be pressed into the second sliding hole K-2, causing the bottom of the second slider 201a-3 to protrude from the bottom of the second sliding hole K-2; the bottom of the second slider 201a-3 will press the pressure block 202c-1, causing the pressure block 202c-1 to slide downwards, and the pressure block 202c-1 will in turn press the connecting block 202c-2, causing the connecting block 202c-2 to... 2c-2 overcomes the elastic force of the fifth spring 202c-3 and slides into the locking cavity K-6. After the connecting block 202c-2 slides into the locking cavity K-6, the two ends of the connecting block 202c-2 will block between the two locking blocks 202d-1. Therefore, even if the third slider 202a slides to the point where the locking block 202d-1 is stuck in the slot W-4 at a shallower depth than the first sliding slot W-1, and the rounded length of the locking block 202d-1 is greater than the depth of the first sliding slot W-1, the locking block 202d-1 still cannot retract into the locking cavity K-6 under pressure, and the quick fixing mechanism 200 as a whole cannot slide down.

[0050] It should be noted that after the flange part is fully inserted between the first slider 201a-1 and the first limiting block 201c, the connecting block 202c-2 will be reset under the elastic force of the fifth spring 202c-3. At this time, since the third slider 202a is in a squeezed state, the locking block 202d-1, which is in a shallower groove of the locking groove W-4, will slide out of the locking groove W-4 under the downward pressure of the operator, and the entire fixing mechanism 200 will be squeezed and slid downward. After the flange part is inserted into the end of the shaft of the fixed flange part and contacts the end of the hydraulic column 102, the operator can release and open the hydraulic drive assembly of the hydraulic column 102. Under the push of the hydraulic column 102, the flange part will be squeezed out of the outer ring surface of the shaft of the fixed flange part.

[0051] It should also be noted that after the flange part is squeezed out of the outer ring surface of the shaft that fixes the flange part, the operator can hold the disassembly plate 101 and move the flange part and the disassembly device for the flange part on the shaft to the designated position. After that, the operator only needs to press the first slider 201a-1 into the first sliding hole K-1 with both hands to pull the flange part out of the disassembly column 103.

[0052] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
