[0001] The utility model relates to the technical field of saw blade disassembling tools, in particular to a saw blade disassembling tool for a panel splitting machine. Background Art

[0002] A depaneling machine usually refers to a PCB depaneling machine, that is, a circuit board depaneling machine. Depaneling machines are widely used in the electronic product manufacturing industry. At present, there is a very popular cutting scheme for PCB board cutting and depaneling, which is to use the depaneling machine spindle with a diamond saw blade installed for cutting. The cutting effect is good, but the saw blade is often easily deformed and damaged after long-term use, resulting in reduced operating efficiency. Therefore, the saw blade needs to be replaced frequently, and the disassembly of the saw blade is often completed with special tools.

[0003] Existing saw blade disassembly tools are usually of fixed length. When the disassembly environment is relatively complex, it is difficult for people's arms to pass through the narrow gap, which makes it very troublesome to disassemble the saw blade.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a saw blade disassembly tool for a panel splitting machine is proposed. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a saw blade disassembly tool for a panel splitter, comprising a wrench head and a slide groove, an adjustment assembly is arranged at the bottom of the wrench head, and the adjustment assembly comprises an inner handle, a screw nut, a trapezoidal screw, a first bevel gear, a second bevel gear, a hand-cranked wheel and an outer handle, a screw nut is arranged at the lower part of the inner handle, and a trapezoidal screw is passed through the screw nut, a first bevel gear is arranged at the lower part of the outer part of the trapezoidal screw, and the outer part of the first bevel gear is connected to the second bevel gear, a hand-cranked wheel is passed through the middle part of the second bevel gear, the outer handle is sleeved on the outer part of the inner handle, the slide groove is opened on the surface of the wrench head, and arc-shaped plates are fixed on both sides of the surface of the wrench head, and a ratchet is arranged on the outer part of the arc-shaped plate.

[0007] Furthermore, the wrench head and the inner handle are integrated into one structure, and the inner handle is hollow.

[0008] Furthermore, the trapezoidal lead screw and the hand-cranked wheel are perpendicular to each other, and the bottom end of the trapezoidal lead screw is rotatably connected to the outer handle.

[0009] Furthermore, a connecting plate is fixed on the inner side of the ratchet, and a circular ring is fixed on the other end of the connecting plate.

[0010] Further, a sliding pin is inserted through the through groove on the surface of the connecting plate, and a movable plate lip is fixed to the rear end of the sliding pin.

[0011] Further, a locking assembly is installed above the surface of the wrench head, and the locking assembly includes a rotating shaft, a pawl, and a first pin shaft. The pawl is provided on the rotating shaft, and the first pin shaft is fixed to the surface of the pawl.

[0012] Further, the locking assembly further includes a hook spring and a second pin shaft. The outer portion of the first pin shaft is connected to the hook spring, and the other end of the hook spring is connected to the second pin shaft. The second pin shaft is fixedly connected to the wrench head.

[0013] The utility model provides a saw blade disassembling tool for a plate splitting machine, which has the following beneficial effects:

[0014] 1. By manually rotating the hand crank of the utility model, the second bevel gear at the end of the hand crank drives the first bevel gear to drive the trapezoidal lead screw to rotate, so that the lead screw nut drives the inner handle to make a longitudinal displacement along the outside of the trapezoidal lead screw, and the inner handle extends outwards by a certain distance, thus meeting the needs of the working environment.

[0015] 2. The utility model relies on the elastic support of the hook spring to keep the pawl engaged with the ratchet, thereby restricting the ratchet from rotating clockwise and only allowing it to rotate counterclockwise, preventing the hexagonal aperture formed by the combination of six movable plate lips from changing, ensuring the fitting accuracy between the tool and the nut fixed on the saw blade. After the tool is engaged with the nut, grasping the saw blade and rotating the tool in the opposite direction to the direction of tightening the nut can remove the nut and the saw blade.

[0020] The following further describes in detail the implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0021] As Figure 1 and Figure 2 shown, a saw blade disassembling tool for a circuit board cutting machine includes a wrench head 1 and a chute 3. An adjusting component 2 is arranged at the bottom of the wrench head 1. The adjusting component 2 includes an inner handle 201, a lead screw nut 202, a trapezoidal lead screw 203, a first bevel gear 204, a second bevel gear 205, a hand crank 206 and an outer handle 207. A lead screw nut 202 is arranged below the interior of the inner handle 201, and a trapezoidal lead screw 203 is inserted through the lead screw nut 202. A first bevel gear 204 is arranged below the exterior of the trapezoidal lead screw 203, and a second bevel gear 205 is connected to the exterior of the first bevel gear 204. A hand crank 206 is inserted through the middle of the second bevel gear 205. The outer handle 207 is sleeved on the exterior of the inner handle 201. The wrench head 1 and the inner handle 201 are of an integrated structure. The inner handle 201 is of a hollow structure. The trapezoidal lead screw 203 and the hand crank 206 are perpendicular to each other, and the bottom end of the trapezoidal lead screw 203 is rotatably connected to the outer handle 207. The chute 3 is opened on the surface of the wrench head 1, and arc-shaped plate members 4 are fixed on both sides of the surface of the wrench head 1.

[0022] The specific operation is as follows. By manually rotating the hand crank 206, the second bevel gear 205 at the end of the hand crank 206 drives the first bevel gear 204 to drive the trapezoidal lead screw 203 to rotate, realizing that the lead screw nut 202 drives the inner handle 201 to make a longitudinal displacement along the exterior of the trapezoidal lead screw 203, so that the inner handle 201 extends out a certain distance, thus meeting the needs of the working environment.

[0023] As Figure 1 and Figure 3 shown, a ratchet 5 is arranged outside the arc-shaped plate member 4. A connecting plate 6 is fixed to the inner side of the ratchet 5, and a circular ring member 7 is fixed to the other end of the connecting plate 6. A sliding pin 8 is inserted through a through groove on the surface of the connecting plate 6, and a movable plate lip 9 is fixed to the rear end of the sliding pin 8. A locking component 10 is installed above the surface of the wrench head 1. The locking component 10 includes a rotating shaft 1001, a pawl 1002 and a first pin shaft 1003. A pawl 1002 is arranged on the rotating shaft 1001, and a first pin shaft 1003 is fixed to the surface of the pawl 1002. The locking component 10 further includes a hook spring 1004 and a second pin shaft 1005. The first pin shaft 1003 is externally connected to the hook spring 1004, and the other end of the hook spring 1004 is connected to the second pin shaft 1005. The second pin shaft 1005 is fixedly connected to the wrench head 1.

[0024] The specific operation is as follows. Relying on the elastic support of the hook spring 1004, the pawl 1002 remains engaged with the ratchet wheel 5, thereby restricting the ratchet wheel 5 to rotate counterclockwise only and preventing it from rotating clockwise. This avoids changes in the hexagonal aperture formed by the combination of the six movable plate lips 9, ensuring the fitting accuracy between the tool and the nut fixed on the saw blade. After the tool and the nut are engaged, grasp the saw blade and rotate the tool in the direction opposite to the direction of tightening the nut, and the nut can be removed and the saw blade can be removed.

[0025] In summary, for the saw blade disassembly tool of this plate splitting machine, during use, first, the thread of the nut for fixing the saw blade rotates in the opposite direction to the rotation of the saw blade. When the saw blade rotates during work, the nut has a tendency to tighten with the rotation. When it is necessary to disassemble and replace the saw blade, first adjust the length of the tool according to the needs of the working environment, that is, manually rotate the handwheel 206. The second bevel gear 205 at the end of the handwheel 206 drives the first bevel gear 204 to drive the trapezoidal lead screw 203 to rotate, realizing that the lead screw nut 202 drives the inner handle 201 to make a longitudinal displacement along the outside of the trapezoidal lead screw 203, so that the inner handle 201 extends out a certain distance or retracts into the outer handle 207;

[0026] Then, adjust the tool according to the size of the nut, that is, place the wrench head 1 against the saw blade so that the nut is located at the opening in the middle of the wrench head 1. Since the arc-shaped plate member 4 penetrates through the arc-shaped groove on the surface of the ratchet wheel 5, by rotating the ratchet wheel 5, the connecting plate 6, and the ring member 7 counterclockwise, the connecting plate 6 drives the sliding pin 8 to displace, causing the movable plate lip 9 to slide in the chute 3, and enabling the hexagonal aperture formed by the combination of the six movable plate lips 9 to be consistent with the nut size;

[0027] After the tool and the nut are engaged, hold the outer handle 207 with one hand to fix the nut with the wrench head 1, and hold the saw blade with the other hand and rotate the tool in the direction opposite to the direction of tightening the nut, and the nut can be removed and the saw blade can be removed. Since the pawl 1002 remains engaged with the ratchet wheel 5 relying on the elastic support of the hook spring 1004, it avoids the ratchet wheel 5 rotating clockwise during the disassembly process, causing the tool to loosen, ensuring the fitting accuracy between the tool and the nut fixed on the saw blade. After the disassembly is completed, the pawl 1002 can be manually rotated to make the ratchet wheel 5 rotate clockwise, and the hexagonal aperture formed by the combination of the six movable plate lips 9 returns to its initial size.

[0028] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.
