[0002] On an automated pulsating assembly line, the motor drives the main drive shaft during pulsation, and the tension of the timing belt is adjusted using the guide pulleys and tensioner pulleys mounted on the guide rails. When the timing belt reaches the end of its service life or breaks, it must be disassembled, reassembled, and debugged. Due to the large 55mm nut used to lock the tensioner, conventional wrenches are impractical due to space constraints at the nut mounting area, significantly impacting the work process and consuming significant time and effort. Summary of the Invention

[0003] In order to solve the problems existing in the prior art, the purpose of the present invention is to provide a nut disassembly and assembly device and a method of using the same, which can realize the disassembly and assembly of nuts in a safer, more convenient and more efficient manner.

[0004] The technical solution adopted in the present invention is as follows:

[0005] A nut disassembling and assembling device comprises a supporting seat, an inner hexagonal sleeve, an outer hexagonal guide rod and a cylindrical supporting rod;

[0006] One end of the cylindrical support rod is fixedly connected to the support base;

[0007] The overall shape of the cross section of the outer hexagonal guide rod is a regular hexagon, and a circular through hole is provided at the axis of the outer hexagonal guide rod. The outer hexagonal guide rod is sleeved on the outside of the cylindrical support rod through the circular through hole thereon;

[0008] The axis of the inner hexagonal sleeve is provided with a regular hexagonal through hole, and the inner hexagonal sleeve is sleeved on the outside of the outer hexagonal guide rod through the regular hexagonal through hole.

[0009] Preferably, the support seat includes a protective bracket and a sliding base, the lower end of the protective bracket is fixedly connected to the sliding base, and the upper end of the protective bracket is fixedly connected to the cylindrical support rod.

[0010] Preferably, the sliding base is provided with a sliding groove on one side below the cylindrical support rod, and the sliding groove is for one side of the lower wing edge of the guide rail to extend into. The sliding base can slide along the lower wing edge of the guide rail through the sliding groove.

[0011] Preferably, the sliding groove is opened from the side wall of the sliding base to the interior of the sliding base, and the depth of the sliding groove is greater than half the width of the lower wing of the guide rail.

[0012] Preferably, the horizontal radial direction of the cylindrical support rod is recorded as the width direction of the sliding base, and the axial direction of the cylindrical support rod is recorded as the length direction of the sliding base;

[0013] The width of the sliding base is greater than the radial dimension of the inner hexagonal sleeve, the length of the sliding base is greater than the length of the cylindrical support rod, and the other end of the cylindrical support rod does not extend out of the edge of the sliding base.

[0014] Preferably, the lower end of the protective bracket is welded to the sliding base or fixedly connected by bolts.

[0015] Preferably, the upper end of the protective bracket is welded to the cylindrical support rod or fixedly connected by bolts.

[0016] Preferably, there is a clearance fit between the circular through hole and the cylindrical support rod.

[0017] Preferably, there is a clearance fit between the regular hexagonal through hole and the outer hexagonal guide rod.

[0018] The method for using the nut disassembly and assembly device of the present invention includes a disassembly process and an assembly process:

[0019] The disassembly process is as follows:

[0020] Move the support base so that the cylindrical support rod is coaxial with the locking nut mounting bolt;

[0021] Slide the inner hexagonal sleeve and / or the outer hexagonal guide rod so that one end of the inner hexagonal sleeve is sleeved onto the outside of the lock nut, and the other end of the inner hexagonal sleeve is still sleeved onto the end of the outer hexagonal guide rod, while the outer hexagonal guide rod is sleeved onto the cylindrical support rod;

[0022] Rotate the outer hexagonal guide rod, which drives the inner hexagonal sleeve to rotate. The inner hexagonal sleeve loosens the lock nut until the lock nut is completely removed from the lock nut mounting bolt. At this time, the lock nut remains in the inner hexagonal sleeve. Then, push the inner hexagonal sleeve toward the outer hexagonal guide rod to push out the lock nut remaining in the inner hexagonal sleeve through the outer hexagonal guide rod, thus completing the removal process of the lock nut.

[0023] Move the support base and remove the next locking nut according to the above disassembly process;

[0024] The installation process is as follows:

[0025] Move the hexagonal sleeve so that it extends beyond at least the thickness of the lock nut, and install the lock nut into the hexagonal sleeve;

[0026] Move the support base so that the cylindrical support rod is coaxial with the locking nut mounting bolt;

[0027] Slide the hexagonal socket and / or hexagonal guide rod until the lock nut contacts the end of the lock nut mounting bolt;

[0028] Rotate the outer hexagonal guide rod, which drives the inner hexagonal sleeve to rotate. The inner hexagonal sleeve screws the lock nut into the lock nut mounting bolt until the lock nut reaches the pre-tightening force. Then slide the inner hexagonal sleeve toward the outer hexagonal guide rod and remove it from the lock nut to complete the installation process of the lock nut.

[0029] Move the support base and install the next locking nut according to the above installation process.

[0030] The present invention has the following beneficial effects:

[0031] In a nut disassembly and assembly device of the present invention, the outer hexagonal guide rod is sleeved on the outside of the cylindrical support rod through the circular through hole thereon, so that the outer hexagonal guide rod can slide freely on the cylindrical support rod, and the outer hexagonal guide rod can rotate freely around the axis outside the cylindrical support rod; the inner hexagonal sleeve is sleeved on the outside of the outer hexagonal guide rod through the regular hexagonal through hole thereon, so that the inner hexagonal sleeve can slide freely on the outer hexagonal guide rod, and when the outer hexagonal guide rod rotates around the axis, it can transmit torque to the inner hexagonal sleeve through the regular hexagonal through hole; therefore, when the locking nut is assembled and disassembled by the present invention, the outer hexagonal guide rod is driven to rotate, so that the inner hexagonal sleeve can tighten or loosen the locking nut, thereby realizing the assembly and disassembly of the locking nut. The inner hexagonal sleeve, outer hexagonal guide rod and cylindrical support rod in the present invention can be extended and retracted to a certain distance as a whole. Therefore, the outer hexagonal guide rod can be rotated by a wrench at a distance far from the locking nut to apply torque to the locking nut, avoiding the problem that the traditional wrench needs to be close to the locking nut to apply torque, but cannot be used normally due to the space limitation of the locking nut installation position. Therefore, the nut disassembly and assembly device of the present invention can complete the smooth disassembly and assembly of the locking nut used to lock the tensioner on the pulsating assembly automatic production line. Compared with the existing technology, when the outer hexagonal guide rod is rotated, the wrench can rotate smoothly in a full circle in the present invention, so the disassembly and assembly efficiency is higher. Furthermore, when removing the locking nut, the locking nut removed from the locking nut mounting bolt remains in the hexagonal sleeve and does not fall directly, causing a safety risk. Furthermore, when installing the locking nut, the locking nut is initially placed at the end of the hexagonal sleeve, avoiding manual insertion of the locking nut onto the locking nut mounting bolt. Furthermore, due to the heavy weight and high inertia of the locking nut, manual insertion of the locking nut may cause the operator to fall or bump during manual operation, thereby preventing injury. Therefore, disassembly using the nut disassembly and assembly device of the present invention is also safer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0042] See also Figure 1(a)-Figure 3(b) as well as Figure 8 The nut disassembly and assembly device of the present invention includes a support base, an inner hexagonal sleeve 1, an outer hexagonal guide rod 2 and a cylindrical support rod 3; the left end of the cylindrical support rod 3 is fixedly connected to the support base; see Figure 2 (a), Figure 2 (b) and Figure 8 The overall shape of the cross section of the outer hexagonal guide rod 2 is a regular hexagon, and a circular through hole 2-1 is provided at the axis of the outer hexagonal guide rod 2. The outer hexagonal guide rod 2 is sleeved on the outside of the cylindrical support rod 3 through the circular through hole 2-1 thereon; see Figure 1 (a), Figure 1 (b) and Figure 8 The axis of the inner hexagonal sleeve 1 is provided with a regular hexagonal through hole 1-1, and the inner hexagonal sleeve 1 is sleeved on the outside of the outer hexagonal guide rod 2 through the regular hexagonal through hole 1-1 thereon.

[0043] See also Figure 7The method for using the nut disassembly and assembly device of the present invention includes a disassembly process and an installation process, which are specifically as follows:

[0044] The disassembly process is as follows:

[0045] Move the support seat so that the cylindrical support rod 3 is coaxial with the locking nut mounting bolt 9, see Figure 7 Step ① in the

[0046] Slide the inner hexagonal sleeve 1 and / or the outer hexagonal guide rod 2 to the right, so that one end of the inner hexagonal sleeve 1 is sleeved on the outside of the lock nut 8, and the other end of the inner hexagonal sleeve 1 is still sleeved on the end of the outer hexagonal guide rod 2, while the outer hexagonal guide rod 2 is sleeved on the cylindrical support rod 3. Figure 7 Step ② in the

[0047] Rotate the outer hexagonal guide rod 2, which drives the inner hexagonal sleeve 1 to rotate. The inner hexagonal sleeve 1 loosens the lock nut 8 until the lock nut 8 is completely removed from the lock nut mounting bolt 9. At this time, the lock nut 8 stays in the inner hexagonal sleeve 1. Figure 7 Then, by pushing the inner hexagonal sleeve 1 toward the outer hexagonal guide rod 2, the locking nut 8 remaining in the inner hexagonal sleeve 1 is pushed out through the outer hexagonal guide rod 2 to achieve the disassembly process of the locking nut 8, see Figure 7 Step ④ in the above code;

[0048] Then move the support seat and remove the next locking nut 8 according to the disassembly process until all the locking nuts 8 are removed.

[0049] The installation process is as follows:

[0050] Move the hexagonal sleeve 1 so that it extends beyond at least the thickness of the lock nut 8, and install the lock nut 8 into the hexagonal sleeve 1; move the support base so that the cylindrical support rod 3 is coaxial with the lock nut mounting bolt 9, see Figure 7 The status of step ④;

[0051] Slide the inner hexagonal sleeve 1 and / or the outer hexagonal guide rod 2 so that the lock nut 8 abuts against the end of the lock nut mounting bolt 9, see Figure 7 The status of step ③;

[0052] Rotate the outer hexagonal guide rod 2, which drives the inner hexagonal sleeve 1 to rotate. The inner hexagonal sleeve 1 screws the lock nut 8 into the lock nut mounting bolt 9 until the lock nut 8 reaches the pre-tightening force. Figure 7 Then slide the inner hexagonal sleeve 1 toward the outer hexagonal guide rod 2 and leave it from the lock nut 8 to complete the installation process of the lock nut 8. Figure 7 The status of step ①;

[0053] Move the support base and install the next locking nut 8 according to the installation process until all the locking nuts 8 are installed.

[0054] As a preferred embodiment of the present invention, the support seat includes a protective bracket 5 and a sliding base 6. The lower end of the protective bracket 5 is fixedly connected to the sliding base 6, and the upper end of the protective bracket 5 is fixedly connected to the cylindrical support rod 3. The sliding base 6 can facilitate the movement of the entire nut disassembly and assembly device, further improving the disassembly and assembly efficiency of the locking nut 8.

[0055] As a preferred embodiment of the present invention, see Figure 5 、 Figure 7 as well as Figure 8 The sliding base 6 is provided with a slide groove 6-1 on one side below the cylindrical support rod 3, and the slide groove 6-1 is provided for the lower wing side of the guide rail 7 ( Figure 7 The left side is shown) inserted, and the sliding base 6 can slide along the lower wing edge of the guide rail 7 through the slide groove 6-1, wherein the guide rail 7 is the track for installing the guide wheel and the tension wheel of the master and driven wheel assembly on the pulsation assembly automatic production line. The shape of the guide rail 7 is an I-shaped, see Figure 7 The sliding base 6 can slide along the lower wing edge of the guide rail 7 through the slide groove 6-1, making the movement of the entire nut disassembly and assembly device of the present invention more convenient and without interfering with the positions of other surrounding equipment. In addition, the sliding base 6 also serves to receive the locking nut 8 that has been removed or is ready to be installed, so that the risk of the locking nut 8 falling from a high position is further reduced, thereby making the nut disassembly and assembly device of the present invention safer.

[0056] As a feasible solution of the present invention, the chute 6-1 is moved from the right side wall of the sliding base 6 (see Figure 7 and Figure 8 ) is opened to the interior of the sliding base 6, and the depth of the slide groove 6-1 is greater than half the width of the lower wing of the guide rail track 7, so that the left side of the lower wing of the guide rail track 7 can basically extend into the slide groove 6-1, making the sliding base 6 more stable and safer to install on the guide rail track 7.

[0057] As a preferred embodiment of the present invention, the horizontal radial direction of the cylindrical support rod 3 is recorded as the width direction of the sliding base 6 ( Figure 7 The axial direction of the cylindrical support rod 3 is recorded as the length direction of the sliding base 6 ( Figure 7The width of the sliding base 6 is greater than the radial dimension of the inner hexagonal sleeve 1, and the length of the sliding base 6 is greater than the length of the cylindrical support rod 3. The right end of the cylindrical support rod 3 does not extend beyond the edge of the sliding base 6. The purpose of this is to allow the locking nut 8 that remains in the inner hexagonal sleeve 1 to be pushed out through the outer hexagonal guide rod 2. The locking nut 8 can fall directly onto the sliding base 6, but it is not easy to continue falling from the sliding base 6, ensuring the safety of the operator. Of course, the operator can also directly remove the locking nut 8 that remains in the inner hexagonal sleeve 1 with a steady hand. In addition, the sliding base 6 of this structure can catch the inner hexagonal sleeve 1, the outer hexagonal guide rod 2 and the locking nut 8 that fall out, ensuring the safety of the operator.

[0058] As a feasible solution of the present invention, see Figure 5 and Figure 6 The lower end of the protective bracket 5 is welded or bolted to the sliding base 6. The lower end of the protective bracket 5 and the sliding base 6 can also be connected by a rotational connection, which facilitates changing the direction of the cylindrical support rod 3 in the horizontal plane and facilitating the placement of the lock nut 8 in the hexagonal sleeve 1 or the removal of the lock nut 8 from the hexagonal sleeve 1.

[0059] As a feasible solution of the present invention, the upper end of the protective bracket 5 is welded or fixedly connected to the cylindrical support rod 3 by bolts. When the protective bracket 5 is connected to the cylindrical support rod 3, the angle must be kept stable to prevent the cylindrical support rod 3 from swinging in the vertical plane.

[0060] As a feasible solution of the present invention, there is a clearance fit between the circular through hole 2-1 and the cylindrical support rod 3, thereby facilitating relative rotation between the outer hexagonal guide rod 2 and the cylindrical support rod 3, reducing rotational resistance, and also facilitating relative sliding axially between the outer hexagonal guide rod 2 and the cylindrical support rod 3.

[0061] As a feasible solution of the present invention, there is a clearance fit between the regular hexagonal through hole 1-1 and the outer hexagonal guide rod 2, so that the inner hexagonal sleeve 1 and the outer hexagonal guide rod 2 can slide axially with each other, which is beneficial to the operation of the operator.

The inner hexagonal sleeve 1 loosens the lock nut 8 until the lock nut 8 is completely removed from the lock nut mounting bolt 9. At this time, the lock nut 8 stays in the inner hexagonal sleeve 1. Figure 7Step ③; then push the inner hexagonal sleeve 1 toward the outer hexagonal guide rod 2, push out the locking nut 8 that remains in the inner hexagonal sleeve 1 through the outer hexagonal guide rod 2, and then take out the locking nut 8 by hand, or push the locking nut 8 that remains in the inner hexagonal sleeve 1 directly onto the sliding base 6 through the outer hexagonal guide rod 2, and then take away the locking nut 8 to achieve the disassembly process of the locking nut 8, see Figure 7 Step ④ in the above code;

[0070] Then push the sliding base 6 to slide along the lower wing edge of the guide rail 7, and remove the next locking nut 8 according to the disassembly process until all the locking nuts 8 are removed.

[0077] The nut disassembly and assembly device provided by the present invention is mainly used on the guide rail body of the pulsating assembly automatic production line. Due to the limited operating space on the operating guide rail body and the weight of the tensioner body of about 5kg, if the body accidentally falls, it is easy to cause a safety accident. If the belt breaks or the synchronous belts are replaced in batches, the tensioner pulleys (more than 400) need to be disassembled, which reduces work efficiency. The use of this special device of the present invention solves this problem well. This special device is easy to operate, safe and reliable, improves installation and debugging efficiency, and has significant economic benefits.
