[0033] The following will describe the embodiments of the present invention in conjunction with Figures 1 to 3 , to describe the embodiments of the present invention.

[0034] According to an embodiment of the present invention, as shown in Figure 1 and Figure 2As shown, a tooling for disassembling and assembling a crusher bearing nut is provided, mainly including: a tooling body 1. The tooling body 1 includes a connected fixing part 101 and a handle part 102. The fixing part 101 is provided with a through hole 103 and is adapted to be sleeved outside the nut 2 of the crusher bearing through the through hole 103. A plurality of card slots 201 are provided at intervals on the outer side of the nut 2. A plurality of claw fingers 104 corresponding to the plurality of card slots 201 one by one are provided at intervals on the hole wall of the through hole 103. The plurality of claw fingers 104 are engaged with the plurality of card slots 201 to fix the tooling body 1 and the nut 2.

[0035] For the tooling for disassembling and assembling a crusher bearing nut provided by the embodiment of the present utility model, first, the fixing part 101 is sleeved outside the nut 2 by using the through hole 103 of the fixing part 101, and at the same time, the plurality of claw fingers 104 are engaged in the plurality of card slots 201 of the nut 2, so that the fixing part 101 is fixed to the nut 2. Since the fixing part 101 is connected to the handle part 102, only by rotating the handle part 102 can the installation and disassembly of the nut 2 and the bearing be realized, which is convenient and fast, beneficial to ensuring the integrity of the nut 2, the nut 2 can be reused, the use cost is low, and it is easy to lock the nut 2.

[0036] Specifically, the nut 2 of the crusher bearing is generally a round nut, with a threaded hole inside, forming a threaded connection with the external thread on the outer side of the bearing. When disassembling and assembling the nut 2 of the crusher bearing, the operator can directly hold and rotate the handle part 102, thereby driving the fixing part 101 and the nut 2 to rotate; or can also choose to use a tool to strike the handle part 102 to make the fixing part 101 drive the nut 2 to rotate, for example, using a hammer to strike the handle part 102.

[0037] It should be noted that the embodiment of the present utility model does not limit the structure of the claw fingers 104, and any existing structure can be selected according to needs.

[0038] In one embodiment, as Figure 2 shown, the claw finger 104 includes a fixed section 1041 and an extension section 1042 connected at an angle. The fixed section 1041 is fixedly arranged on one side of the fixing part 101, and the extension section 1042 extends towards the through hole 103 and is adapted to be engaged with the card slot 201 of the nut 2. The claw finger 104 is fixedly connected to the fixing part 101 through the fixed section 1041 and is engaged with the card slot 201 of the nut 2 through the extension section 1042, with a simple structure, convenient manufacturing, and low manufacturing cost.

[0039] Specifically, the fixed section 1041 and the extension section 1042 are connected at 90 degrees. The fixed section 1041 is integrally formed on one side surface of the fixing part 101 first, and then extends to the hole wall of the through hole 103 to form the extension section 1042, having a high structural strength.

[0040] Furthermore, in one embodiment, the extension segment 1042 is a square prism, and the card slot 201 is a square groove. The connection is firm through the cooperation and clamping of the square prism and the square groove.

[0041] In one embodiment, at least one side of the handle portion 102 is provided with a flanging 105, and the outer side surface of the flanging 105 forms a striking surface.

[0042] In the embodiment of the present utility model, when disassembling and installing the nut 2, a tool can be used to apply a force to the striking surface to drive the fixing portion 101 to rotate, so that the nut 2 is tightened or loosened, thereby reducing the difficulty of disassembling and installing the nut 2. By providing the flanging 105, the structural strength of the handle portion 102 can be improved, which is beneficial to extending the service life of the tooling body 1. For example, by hitting the flanging 105 with a hammer, the fixing portion 101 is driven to rotate.

[0043] Furthermore, in one embodiment, the striking surface is inclined inward, which is convenient for manually using a tool to apply a force to the striking surface, that is, it is further convenient for disassembling and installing the nut 2.

[0044] Exemplarily, as Figure 1 and Figure 2 shown, opposite flangings 105 are respectively provided on opposite sides of the handle portion 102, and an operator can choose to strike any one of the flangings 105 for use.

[0045] Of course, in some other embodiments, the striking surface can also be adapted to the corresponding tool and select other shapes, such as being set as an arc surface.

[0046] In one embodiment, the breaker bearing nut disassembly and installation tooling further includes a washer. The washer is detachably inserted into the through hole 103. The washer is used to protect the nut 2 and the tooling body 1 and prevent the nut 2 and the tooling body 1 from being damaged. The washer can be sleeved on the outside of the nut 2 or can be provided on the hole wall of the through hole 103.

[0047] In one embodiment, the hole wall of the through hole 103 is provided with anti-slip lines, which can further improve the installation stability between the tooling body 1 and the nut 2.

[0048] It should be noted that the embodiment of the present utility model does not limit the shape of the through hole 103, and a regular hole or an irregular hole can be selected according to needs.

[0049] In one embodiment, the through hole 103 is a regular hole. Regular holes include round holes, oval holes, polygon holes, etc. The through hole 103 is set as a regular hole. On the one hand, it is convenient for the fixing portion 101 to be sleeved outside the nut 2. On the other hand, it is convenient for the machining manufacture of the through hole 103 and reduces the hole opening cost.

[0050] Exemplarily, as Figure 2As shown, the through hole 103 is a round hole. Since the crusher bearing nut 2 is generally annular and the outer side is circular. Therefore, setting the through hole 103 as a round hole facilitates the fixing part 101 to be sleeved outside the nut 2.

[0051] In addition, the embodiment of the present invention does not limit the number of through holes 103 either, and two, three or more than three can be selected and set according to needs.

[0052] In one embodiment, as Figure 1 and Figure 2 shown, the through hole 103 is provided with four claws 104, and the four claws 104 are equally spaced. By setting the four equally spaced claws 104, a cross structure is formed, which is beneficial to sharing the force for disassembling and assembling the nut 2, reducing stress concentration, and avoiding damage to the clamping joint of the nut 2 and the tooling body 1.

[0053] Correspondingly, as Figure 3 shown, four slots 201 are equally spaced on the circumferential side of the nut 2. The four claws 104 are respectively clamped in the four slots 201.

[0054] It should be noted that the embodiment of the present invention does not limit the connection between the fixing part 101 and the handle part 102 either. The fixing part 101 and the handle part 102 can adopt a clamping fixed structure, for example, connected by a snap-fastener slot 201, which is convenient for installation and disassembly, or can adopt a fastener fixed structure, with a firm connection.

[0055] In one embodiment, the multiple claws 104, the fixing part 101 and the handle part 102 are integrally formed, with relatively high structural strength, convenient for processing and manufacturing, and beneficial to further reducing the use cost.

[0056] Exemplarily, the multiple claws 104, the fixing part 101 and the handle part 102 are integrally cast by cast iron.

[0057] The working principle of the embodiment of the present invention is as follows:

[0058] First, the fixing part 101 is sleeved on the nut 2. At the same time, the four claws 104 respectively clamp the four slots 201 of the nut 2 tightly. Then, use a hammer to strike the flange 105 of the handle part 102, driving the nut 2 to rotate clockwise or counterclockwise, so as to realize the installation and disassembly of the nut 2 and the crusher bearing.

[0059] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
