Description

Technical Field

[0001] The present invention relates to the technical field of disassembly tools, belonging to the field of the international patent classification number B25B, and specifically relates to a disassembly device for practical training. Background Art

[0002] In higher education, more and more attention has been paid to professional practical training, which can lay a foundation for students in advance when they enter the professional positions. In vocational education, higher education institutions have launched professional practical training in many aspects, and by providing a teaching platform for simulated practical training, it can provide opportunities for students to exercise their hands-on skills in practical courses.

[0003] During the practical training process of installing and debugging professional equipment in majors such as machinery, electricity, and automobiles, generally, the equipment needs to be assembled to the designated position on the training bench and fastened with bolts of different sizes. After a student completes one practical training, the equipment for simulated practical training will be disassembled, so as to facilitate the next student to carry out practical training, which can achieve the effect of repeated training, thereby improving the proficiency and operation efficiency of practical training. However, the conventional method of disassembling practical training equipment uses various specifications of manual wrenches to disassemble hexagon bolts. However, the manual wrench needs to be operated repeatedly several times before it can be loosened, and in the narrow area of equipment installation, the manual wrench cannot be fully utilized. Therefore, an electric wrench is used to replace different sockets to complete the disassembly operation of hexagon bolts. However, during the disassembly process of practical training equipment, it is necessary to repeatedly search for and replace sockets of different specifications, so that when replacing sockets of different specifications, they need to be stored, and during the practical training process, the sockets will roll and be lost, which is extremely troublesome for the disassembly operation of practical training equipment; therefore, we propose a disassembly device for practical training.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The disassembly device for practical training drives the pull sleeve and the positioning pin to move along the slide groove on the side of the transmission shaft through the pull rod. At this time, the quadrangular pin is pulled out from the docking part of the sleeve head, and the worm and the worm wheel are driven by the finger when the knob is rubbed, so that the rotating worm wheel drives the large synchronous wheel to rotate, thereby driving the movable sleeve on the outer wall of the synchronous belt to change its position.

[0020] 2. The disassembly device for practical training presses the sleeve head to drive the docking part into the movable sleeve, and at the same time, the shallow arc groove and the guide steel ball are connected in a rolling manner. When the deep arc groove and the shallow arc groove are connected with the corresponding locking steel balls and the guide steel balls, it can ensure that the magnet ring 2 in the middle of the outer wall of the docking part is in the upper position of the magnet ring 1. At this time, due to the repulsive force generated by the same polarity of the two, the sleeve head has a continuous locking effect after clamping, which can prevent the sleeve head from loosening and falling off during the operation of the disassembly device;

[0021] 3. When operating the disassembly device for training to disassemble the equipment on the training operating table, the electric wrench handle is pulled upward to make the tooth column slide along the tooth groove in a directional manner.

After the electric wrench handle and the drive motor have completed the angle adjustment, it is convenient for personnel to operate the disassembly device at different angles, and it is convenient to realize multi-mode handheld operation when disassembling the hexagonal bolts of the training equipment. At the same time, by adjusting the angle of the electric wrench handle of the device, it is convenient to adjust the posture of holding the device, so that the device can adapt to the complex layout scenarios of different training equipment.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , the present invention provides a technical solution: a disassembly device for training, including a driving motor 1, an electric wrench handle 3, a transmission mechanism 4, and a socket head 6. A rotating assembly 2 is provided on one side of the driving motor 1, and the rotating assembly 2 is movably connected to one end of the electric wrench handle 3. A stepless speed change power switch is provided on the lower side of the electric wrench handle 3, and the electric wrench handle 3 can be held by an operator for operation. A rechargeable battery 31 is installed at one end of the electric wrench handle 3 away from the rotating assembly 2. The output end of the driving motor 1 is connected to the transmission mechanism 4. An operation button for switching the forward and reverse rotation is also provided on the side surface of the driving motor 1;

[0034] A storage box 5 is installed on the side of the driving motor 1 close to the transmission mechanism 4. The storage box 5 is composed of a through port 51, a large synchronous pulley 52, a small synchronous pulley 53, a synchronous belt 54, a movable sleeve 55, a worm wheel disc 56, a worm 57, and a knob 58. A through port 51 is opened on one side surface of the storage box 5. A large synchronous pulley 52 is connected by a bearing to the side of the storage box 5 away from the through port 51. A small synchronous pulley 53 is connected by a bearing to the side of the storage box 5 close to the through port 51. A synchronous belt 54 is sleeved outside the large synchronous pulley 52 and the small synchronous pulley 53. A movable sleeve 55 is fixed to the outer wall of the synchronous belt 54. A socket head 6 for disassembling external hexagonal bolts is connected to the lower side of the movable sleeve 55;

[0035] The central axis of the large synchronous pulley 52 penetrates and extends out of the storage box 5 and is welded to the center of the worm wheel disc 56. One side of the worm wheel disc 56 is connected to the worm 57, and both ends of the worm 57 are connected to the bearing seats on the outer side surface of the storage box 5. The end of the worm 57 that penetrates and extends out of the bearing seat is connected to the knob 58. The distance between the outer side surface of the synchronous belt 54 and the inner wall surface of the storage box 5 is equal.

[0036] In specific implementation, by arranging a large synchronous pulley 52 and a small synchronous pulley 53 in the storage box 5, when the large synchronous pulley 52 and the small synchronous pulley 53 rotate, it can ensure that the synchronous belt 54 steadily drives the movable sleeve 55 to change its position. The socket head 6 is set to different specifications according to actual needs, and the docking parts 61 of all the socket heads 6 have the same size, so as to ensure that the docking parts 61 of all the socket heads 6 can be assembled and docked with the movable sleeve 55;

[0037] The movable sleeves 55 are fixedly arranged at equal intervals on the outer side of the synchronous belt 54. According to the need to disassemble the hexagonal bolts of specific training equipment, a series of socket heads 6 can be installed in each movable sleeve 55, so that the storage box 5 can clamp socket heads 6 of various specifications, ensuring that the disassembly device has a comprehensive applicability effect when disassembling different equipment; the socket heads 6 can also be installed in the movable sleeves 55 at intervals, so as to ensure that the socket heads 6 will not interfere with other components during use; at the same time, multiple socket heads 6 required for the training equipment can be clamped into the movable sleeves 55 in advance, so that there is no need to install the socket heads 6 that are not temporarily used; in addition, multiple frequently used socket heads 6 can be clamped in the movable sleeves 55 close to the small synchronous pulley 53, which is convenient for quick replacement;

[0038] By rubbing the knob 58 with fingers, the knob 58 drives the worm 57 to rotate, so that the worm 57 can drive the worm wheel disc 56 to rotate. The rotating worm wheel disc 56 can drive the coaxial large synchronous pulley 52 to rotate, so that the large synchronous pulley 52 drives the synchronous belt 54 to operate with the assistance of the small synchronous pulley 53. Thus, the synchronous belt 54 can drive the movable sleeve 55 on its outer wall to change its position. When the movable sleeves 55 at different positions drive the socket heads 6 of different specifications to move to the position of the through port 51, it is convenient for the transmission mechanism 4 to switch and dock with different socket heads 6 for use;

[0039] At the same time, since the diameter of the large synchronous pulley 52 is larger than that of the small synchronous pulley 53, when the worm wheel disc 56 rotates, it can drive the large synchronous pulley 52 to rotate. Thus, when the large synchronous pulley 52 rotates, it can accelerate the rotation of the small synchronous pulley 53, which is convenient for quick operation when replacing the socket head 6.

[0040] Please refer to Figure 1 and Figure 2 , the transmission mechanism 4 includes a transmission shaft 41, a top push spring 42, a guide block 43, a quadrangular prism pin 44, a chute 45 and a positioning pin 46. The end of the transmission shaft 41 is fixed to the output end of the driving motor 1. The transmission shaft 41 is of a hollow structure, and the end of the transmission shaft 41 away from the driving motor 1 is open. The upper end of the inner wall of the transmission shaft 41 is welded with the top push spring 42, and the bottom end of the top push spring 42 is welded with the guide block 43. The transmission shaft 41 is inserted into the through port 51 on the surface of the storage box 5;

[0041] A quadrangular prism pin 44 is fixed to the bottom of the guide block 43. A chute 45 is formed on the surface of the transmission shaft 41. A positioning pin 46 is butted against the outer wall of the guide block 43, and the positioning pin 46 is inserted through the chute 45. The guide block 43 and the transmission shaft 41 form an elastic telescopic structure through a pushing spring 42, and the positioning pin 46 and the chute 45 are in sliding connection.

[0042] During specific implementation, when holding the handle 3 of the hand-held electric wrench, the power switch of the stepless speed change is pressed to control the storage battery 31 to supply power to the drive motor 1, so that the drive motor 1 drives the transmission shaft 41 at the output end to rotate. Thus, under the action of the operation button for switching the forward and reverse rotations, it is convenient to change the rotation direction of the transmission mechanism 4;

[0043] And when the transmission shaft 41 rotates, the transmission shaft 41 can drive the quadrangular prism pin 44 at the lower side of the guide block 43 to rotate. Thus, when the quadrangular prism pin 44 rotates, it can drive the butting part 61 to rotate, and further drive the socket head 6 to disassemble the hexagonal bolt when rotating.

[0044] Please refer to Figure 2 , an adjusting mechanism 7 is arranged on one side of the transmission mechanism 4, and the adjusting mechanism 7 is used to pull the quadrangular prism pin 44 to move telescopically. The adjusting mechanism 7 is composed of a pull sleeve 71 and a pull rod 72. The outer side of the transmission shaft 41 is sleeved with the pull sleeve 71, and a U-shaped channel is formed on the inner wall of the pull sleeve 71, and the U-shaped channel of the pull sleeve 71 is butted against the positioning pin 46; a T-shaped rod is fixed to one side of the outer wall of the pull sleeve 71, and the T-shaped rod is movably connected to the lower end of the pull rod 72, and the top of the pull rod 72 is inserted through the side shell of the drive motor 1.

[0045] During specific implementation, when the transmission shaft 41 rotates, it will drive the positioning pin 46 to rotate. By manually pulling the pull rod 72 to slide along the side of the drive motor 1, the pull sleeve 71 on one side of the T-shaped rod is driven to move upward by the pull rod 72. At this time, the pull sleeve 71 will drive the positioning pin 46 to move along the chute 45 on the side of the transmission shaft 41, and will squeeze the pushing spring 42 in the middle of the transmission shaft 41 to contract. Furthermore, the quadrangular prism pin 44 can be pulled out from the butting part 61 of the socket head 6. When the position of the movable sleeve 55 is switched, the socket head 6 can be positioned and placed directly below the through hole 51. At this time, releasing the pull rod 72 can make the pushing spring 42 push the quadrangular prism pin 44 to insert into the butting part 61 after the position is switched, which is convenient for quickly replacing socket heads 6 of different specifications for use.

[0046] Please refer to Figure 1 , Figure 3 and Figure 5, in the middle of the inner wall of the movable sleeve 55, a first magnet ring 551 is embedded and installed. On both sides of the inner wall of the movable sleeve 55 near the first magnet ring 551, guide steel balls 552 are embedded and distributed at equal angles. Inner holes 553 are formed in both the inner wall of the upper edge and the inner wall of the lower edge of the movable sleeve 55, and locking steel balls 555 are welded in the inner holes 553 through anti-loosening springs 554;

[0047] One end of the socket head 6 is provided with a docking portion 61. The middle of the docking portion 61 is a square hole structure, and the size of the square hole matches the size of the quadrangular prism pin 44. A second magnet ring 62 is embedded in the middle of the outer wall of the docking portion 61. Deep arc grooves and shallow arc grooves are symmetrically formed on the outer wall surface of the docking portion 61. The deep arc grooves are slidably connected with the locking steel balls 555, and the shallow arc grooves are in rolling connection with the guide steel balls 552. The second magnet ring 62 and the first magnet ring 551 have the same polarity, so that there is a repulsive force when the two are close to each other.

[0048] During specific implementation, when docking and assembling the docking portion 61 of the socket head 6 with the movable sleeve 55, press the socket head 6 to drive the docking portion 61 to be inserted into the movable sleeve 55, and slidably connect the deep arc groove on the outer wall of the docking portion 61 with the locking steel balls 555, and at the same time, the shallow arc groove is in rolling connection with the guide steel balls 552. When both the deep arc groove and the shallow arc groove are connected with the corresponding locking steel balls 555 and guide steel balls 552, it can be ensured that the second magnet ring 62 in the middle of the outer wall of the docking portion 61 is located above the first magnet ring 551. At this time, due to the repulsive force generated by the same polarity of the two, the socket head 6 has a continuous locking effect after being clamped, which can prevent the socket head 6 from loosening and falling off during the operation of the disassembly device;

[0049] At the same time, the locking steel balls 555 can position the docking portion 61. When the quadrangular prism pin 44 drives the docking portion 61 to rotate, the docking portion 61 will rotate in the movable sleeve 55. The guide steel balls 552 distributed at equal angles can reduce the friction generated when the upper docking portion 61 of the socket head 6 rotates in the movable sleeve 55. When necessary, applying lubricating oil to the locking steel balls 555 and the guide steel balls 552 can better reduce the friction and prevent noise generation.

[0050] Please refer to Figure 1 , Figure 8 and Figure 9 , the rotating assembly 2 is composed of a fixed column 21, a tooth column 22, a limit block 23, a tooth groove 24, an adjustment port 25 and a strong magnet block 26. The fixed column 21 is welded to one side of the outer shell of the drive motor 1, and the tooth column 22 is welded to the upper end of the fixed column 21;

[0051] The limiting block 23 is welded to the end surface of the handle 3 of the electric wrench close to the drive motor 1. A tooth groove 24 is formed in the middle of the limiting block 23. An adjustment opening 25 is formed on one side of the limiting block 23 close to the tooth groove 24. A strong magnet block 26 is embedded and fixed on the inner wall of the tooth groove 24 away from the adjustment opening 25. The tooth groove 24 is slidably connected to the tooth column 22. The diameter of the tooth groove 24 is smaller than the diameter of the adjustment opening 25. The depth of the adjustment opening 25 matches the thickness of the tooth column 22.

[0052] During specific implementation, when operating this disassembly device to disassemble the equipment on the training operation table, by adjusting the angle of the handle 3 of the electric wrench of this device, it is convenient to adjust the holding posture of this device, so that this device can adapt to the complex layout scenarios of different training equipment. When adjusting the angle of the handle 3 of the electric wrench, by pulling up the handle 3 of the electric wrench, the limiting block 23 at the end of the handle 3 of the electric wrench moves upward, so that the strong magnet block 26 inside the limiting block 23 is disengaged from the magnetic attraction with the tooth column 22, and the tooth column 22 will slide directionally along the tooth groove 24. When the tooth column 22 moves to the adjustment opening 25 at the bottom of the tooth groove 24, the tooth column 22 will not be restricted by the tooth groove 24 and the handle 3 of the electric wrench can be rotated.

[0053] Please refer to Figure 6 and Figure 7 , on one side of the drive motor 1 close to the handle 3 of the electric wrench, recesses 11 are symmetrically formed, and the recesses 11 are in a right-angle structure.

[0054] During specific implementation, when turning the handle 3 of the electric wrench, it can rotate around the fixed column 21 on one side of the drive motor 1, so that the limiting block 23 at the end of the handle 3 of the electric wrench will rotate in the recess 11 with a right-angle structure. After adjusting the angles of the handle 3 of the electric wrench and the drive motor 1, it is convenient for personnel to operate this disassembly device at different angles, so that the storage box 5 of this disassembly device can be placed in different orientations, and then by attracting the tooth column 22 with the strong magnet block 26, the tooth column 22 is engaged with the tooth groove 24 again, so that the angles of the handle 3 of the electric wrench and the drive motor 1 can be restricted and locked, which is convenient for multi-way hand-held operation when disassembling the hexagon bolts of the training equipment.

[0055] In summary, when conducting operation training on the training equipment for majors such as machinery, electricity, and automobiles in colleges and universities, the equipment needs to be assembled to the designated position on the training bench. After the training is completed, a disassembly device is required for disassembly to ensure the storage of the components of the training equipment. When holding the handle 3 of the hand-held electric wrench for disassembly operation, the power switch of the stepless speed change is pressed to control the storage battery 31 to supply power to the drive motor 1, so that the drive motor 1 drives the transmission shaft 41 at the output end to rotate. The transmission shaft 41 can drive the quadrangular prism pin 44 under the guide block 43 to rotate, so that the quadrangular prism pin 44 can drive the socket head 6 to rotate and disassemble the hexagon bolt. The drive motor 1 can be switched to be assembled with socket heads 6 of different specifications, which is convenient for quickly disassembling different external hexagon bolts of the training equipment. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0056] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
