Description

Technical Field

[0001] The present invention relates to the technical field of power tools, and particularly to a high-torque electric wrench with an auxiliary cooling function. Background Art

[0002] A torque wrench, also known as a torque adjustable wrench, is a type of wrench. It can be classified by power source into: electric torque wrench, pneumatic torque wrench, hydraulic torque wrench, and manual torque wrench. In actual real life, the application of electric wrenches is increasing. With the development of power tools, they have gradually replaced manual tools and are widely used in industrial manufacturing and maintenance. An electric wrench refers to an electric tool for tightening and loosening bolts and nuts, and is a tool for tightening high-strength bolts. It is used for the initial tightening, final tightening of large hexagon head high-strength bolts in the construction of steel structure bridges, factory buildings, chemical industries, and power generation equipment installations, as well as the initial tightening of twist-off type high-strength bolts, and in occasions where strict requirements are imposed on the torque or axial force of bolt fasteners. During the process of vehicle modification, the electric wrench plays an important role.

[0003] Currently, most of the existing electric wrenches do not have an auxiliary heat dissipation function. After long-term operation, the air circulation inside the device is not smooth, and high temperature will occur, which is not conducive to long-term operation. In severe cases, the internal components of the electric wrench will be burned out, resulting in inoperability. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A high-torque electric wrench with an auxiliary cooling function, comprising: A housing, at the bottom of the inner surface of the housing and near the left end, a motor is installed, the motor provides power for the device, and the output end of the motor is fixedly connected to a disc gear; It further includes: A sleeve assembly, which has an annular connecting piece rotatably connected to the left end of the outer surface of the housing, and the inner surface of the annular connecting piece is fixedly connected to a T-shaped cylinder, and a ring gear is fixedly connected to the outer circular surface of the T-shaped cylinder near the right end, and the disc gear is meshed with the ring gear, and a screw is threadedly connected to the left end of the outer surface of the annular connecting piece near the edge, and a screwing module is arranged inside the annular connecting piece near the screw, and a clamping module is arranged at the right end of the outer surface of the annular connecting piece, and a lever is fixedly connected to the central position of the side surface of the T-shaped cylinder. By driving the disc gear to rotate with the output end of the motor, the T-shaped cylinder is driven to rotate, and then the screwing module will rotate along with it, so as to realize the electric self-rotation; At the same time, by using the forward and reverse rotation of the motor, the T-shaped cylinder can drive the screwing module to rotate counterclockwise and clockwise, and then the bolt can be installed and disassembled; A heat dissipation component, which has an annular guide rail fixedly connected to the inner surface of the housing and close to the position of the T-shaped cylinder, and the T-shaped cylinder passes through the center position of the annular guide rail, and the inner surface of the annular guide rail is slidably connected with a rotating ring, and a blade is fixedly connected to the inner surface of the rotating ring and close to the position of the lever. The blade is inclined. By contacting the lever with the blade and continuously rotating the lever, the blade is pushed to rotate circumferentially. At this time, the rotating blade can fan the air in the housing, so that the air is discharged from the round hole, thereby forming an air circulation. At this time, by using the flow of the gas, the heat inside the housing can be dissipated in time, and the situation of high temperature is not likely to occur, playing a role in cooling.

[0005] Preferably, a handle is fixedly connected to the bottom of the housing, a button is installed on the top right side of the outer surface of the handle, a rear cover plate is fixedly connected to the right end of the outer surface of the housing, and a round hole is opened on the side surface of the rear cover plate. The round hole facilitates the dissipation of heat inside the housing. The round hole penetrates the rear cover plate, and the rear cover plate can be disassembled and installed, which is convenient for installing and disassembling the components inside the housing.

[0006] Preferably, a rotating groove adapted to the annular connecting piece is opened on the left end of the outer surface of the housing to facilitate the rotation of the annular connecting piece. There are three levers, and the three levers are evenly distributed on the side surface of the T-shaped cylinder.

[0007] Preferably, the screwing module includes a screwing base body, the screwing base body is embedded in the central position of the inner part of the T-shaped cylinder, the clamping module is installed at a position close to the right end of the outer surface of the screwing base body, a guiding piece is fixedly connected to the right end of the outer circular surface of the screwing base body, the side surface of the guiding piece is slidably connected to the left end inner surface of the T-shaped cylinder, a stepped hole is opened at the central position of the left end of the outer surface of the screwing base body, and a strip tooth is fixedly connected to the inner surface of the stepped hole. The screwing base body is fixed to the T-shaped cylinder by screws. Furthermore, by disassembling the screws, it is convenient to replace the screwing base body, which is not only convenient for subsequent maintenance work, but also can replace the stepped holes with different apertures, and then can adapt to bolts of different models, with strong adaptability and reduced limitations.

[0008] Preferably, a sliding groove adapted to the guiding piece is opened on the left end of the inner surface of the T-shaped cylinder to facilitate the guiding piece to be embedded in the inner surface of the T-shaped cylinder, and the strip teeth are evenly distributed on the inner surface of the stepped hole.

[0009] Preferably, the clamping module includes a rectangular chute and a clamping notch. The rectangular chute is opened at the right end of the outer surface of the T-shaped cylinder, and the clamping notch is opened at the right end of the outer surface of the screwing base. The positions of the rectangular chute and the clamping notch correspond to each other. A resilient sheet is fixedly connected to the left side of the inner surface of the rectangular chute, and a clamping block is fixedly connected to the side surface of the resilient sheet and close to the side of the clamping notch. When the screw is tightened, not only can the screwing base be fixed to the T-shaped cylinder, making the screwing base not easy to loosen; It can also make the right end of the screw apply a pushing force to the resilient sheet. At this time, the resilient sheet is pressed to elastically deform, so that the clamping block smoothly slides into the clamping notch. At this time, the clamping is completed, and the screwing base will not shake. The structures interact with each other, the connection is compact, and the torque force can be increased.

[0010] Preferably, there are three rectangular chutes, and the three rectangular chutes are evenly distributed at the right end of the outer surface of the T-shaped cylinder. There are three clamping notches, and the three clamping notches are evenly distributed at the right end of the outer surface of the screwing base. The resilient sheet is set to be arc-shaped.

[0011] Preferably, a rotating groove adapted to the rotating ring is opened on the inner surface of the circular ring guide rail. There are six blades, and the six blades are evenly distributed on the inner surface of the rotating ring.

[0012] Preferably, an auxiliary module is arranged at a position close to the right end inside the housing. The auxiliary module includes a supporting square column. The top end of the supporting square column is fixedly connected to the inner surface of the housing. One end of the supporting square column away from the inner surface of the housing is fixedly connected to a conical hopper. A spiral sheet is fixedly connected to the inner surface of the conical hopper. A round rod is fixedly connected to a position close to the left end of the inner surface of the conical hopper. One end of the round rod away from the inner surface of the conical hopper is fixedly connected to a universal rolling ball. The air flow enters the conical hopper and, under the guidance of the spiral sheet, makes the air flow in a swirling state. By using the fact that the aperture of the conical hopper gradually decreases from left to right, the air flow output space decreases at this time, and the gas flow rate increases, thereby accelerating the heat removal; At the same time, the universal rolling ball is used to support the screwing base, and when the screwing base rotates, the universal rolling ball can roll and will not hinder the rotation of the screwing base.

[0013] Preferably, the spiral sheets are evenly distributed on the inner surface of the conical hopper, and the aperture of the conical hopper gradually decreases from left to right, which can increase the gas flow rate.

[0014] The present invention provides a high-torque electric wrench with an auxiliary cooling function. It has the following beneficial effects: 1. The high-torque electric wrench with an auxiliary cooling function drives a disc gear to rotate by the output end of the motor. With the annular connecting piece being rotatably connected to the housing, the T-shaped cylinder is driven to rotate, and then the screwing module rotates along with it, enabling electric self-rotation. At the same time, by using the forward and reverse rotations of the motor, the T-shaped cylinder can drive the screwing module to rotate counterclockwise and clockwise, thereby enabling the installation and removal of bolts.

[0015] 2. The high-torque electric wrench with an auxiliary cooling function is fixed to the T-shaped cylinder by screws. By removing the screws, it is convenient to replace the screwing base, which not only facilitates subsequent maintenance work but also allows for the replacement of stepped holes with different apertures to adapt to bolts of different models, showing strong adaptability.

[0016] 3. For the high-torque electric wrench with an auxiliary cooling function, the end of the bolt is inserted into the stepped hole. At this time, two adjacent strip teeth are stuck at the corner position of the bolt end, and the strip teeth are evenly distributed on the inner surface of the stepped hole, so that multiple corners of the bolt are stuck by two adjacent strip teeth. When the screwing base is driven by the T-shaped cylinder to rotate, multiple corners of the bolt are driven to rotate together, making it not easy to slip and facilitating the screwing of the bolt.

[0017] 4. For the high-torque electric wrench with an auxiliary cooling function, by tightening and fixing the screws, not only can the screwing base be fixed to the T-shaped cylinder to prevent the screwing base from loosening, but also the right end of the screw can apply a pushing force to the elastic piece. At this time, the deformed elastic piece pushes the clamping block downward, and under the guiding action of the rectangular sliding groove, the clamping block smoothly slides into the clamping notch, completing the clamping. The screwing base does not shake, and the structures interact with each other, with a compact connection and an increased torque force.

[0018] 5. For the high-torque electric wrench with an auxiliary cooling function, when the lever contacts the blade and continues to rotate, the blade is pushed to rotate in a circle. At this time, the rotating blade can fan the air in the housing, causing the air to be discharged from the round hole, thereby forming an air circulation. By using the flow of the gas, the heat inside the housing can be dissipated in a timely manner, and it is not easy to reach a high temperature, achieving the cooling function.

[0019] 6. For the high-torque electric wrench with an auxiliary cooling function, the air flow enters the conical hopper and, under the guiding action of the spiral blade, forms a swirling flow state. Since the conical hopper is conical, the air flow output space is reduced, and the gas flow rate is accelerated, thereby accelerating the heat removal. At the same time, the screwing base is supported by universal balls, and when the screwing base rotates, the universal balls can roll without hindering the rotation of the screwing base.

The embodiments are chosen and described in order to better illustrate the principles of the present invention and its practical applications, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0023] The first embodiment is as Figures 1 - 5 shown.

A round hole 9 is opened on the side surface of the rear cover plate 8. The gas inside the housing 1 can pass through the round hole 9. The round hole 9 penetrates the rear cover plate 8. The rear cover plate 8 can be disassembled and installed, which is convenient for installing and disassembling the components inside the housing 1; It also includes: A sleeve assembly 4, which has an annular connecting member 41 rotatably connected to the left end of the outer surface of the housing 1. The inner surface of the annular connecting member 41 is fixedly connected to a T-shaped cylinder 42. On the outer circular surface of the T-shaped cylinder 42 and near the right end, an annular gear ring 43 is fixedly connected. The disk gear 3 is meshed with the annular gear ring 43. On the left end of the outer surface of the annular connecting member 41 and near the edge, a screw 44 is threadedly connected. Inside the annular connecting member 41 and near the screw 44, a screwing module 45 is provided. On the right end of the outer surface of the annular connecting member 41, a clamping module 46 is provided. At the central position of the side surface of the T-shaped cylinder 42, a lever 47 is fixedly connected. Using the motor 2 as a power source, at this time, the output end of the motor 2 drives the disk gear 3 to rotate. Combining the meshing connection between the disk gear 3 and the annular gear ring 43, when the annular connecting member 41 is rotatably connected to the housing 1, the T-shaped cylinder 42 is driven to rotate, and then the screwing module 45 will rotate along with it, so as to realize electric self-rotation; At the same time, by using the forward and reverse rotation of the motor 2, the T-shaped cylinder 42 can drive the screwing module 45 to rotate counterclockwise and clockwise, and then the bolt can be installed and disassembled.

[0024] A rotating groove adapted to the annular connecting member 41 is opened at the left end of the outer surface of the housing 1, which is convenient for the annular connecting member 41 to rotate. There are three levers 47, and the three levers 47 are evenly distributed on the side surface of the T-shaped cylinder 42.

[0025] The screwing module 45 includes a screwing base body 451. The screwing base body 451 is embedded in the central position inside the T-shaped cylinder 42. The clamping module 46 is installed at a position near the right end of the outer surface of the screwing base body 451. A guide member 452 is fixedly connected to the right end of the outer circular surface of the screwing base body 451. Since the screwing base body 451 is embedded in the T-shaped cylinder 42 and the screwing base body 451 is fixed to the T-shaped cylinder 42 by screws 44, by disassembling the screws 44, the side surface of the guide member 452 is slidably connected to the left end inner surface of the T-shaped cylinder 42. A stepped hole 453 is provided at the central position of the left end of the outer surface of the screwing base body 451. A strip tooth 454 is fixedly connected to the inner surface of the stepped hole 453. Different-diameter stepped holes 453 can also be replaced, so as to adapt to bolts of different models, with strong adaptability and reduced limitations.

[0026] A sliding groove adapted to the guide member 452 is provided at the left end of the inner surface of the T-shaped cylinder 42, which facilitates the embedding of the guide member into the inner surface of the T-shaped cylinder. The strip teeth 454 are evenly distributed on the inner surface of the stepped hole 453.

[0027] Press the left end of the screwing base body 451 against the end of the bolt, and make the end of the bolt embed into the stepped hole 453. At this time, two adjacent strip teeth 454 are stuck at the corner position of the bolt end. Since the strip teeth 454 are evenly distributed on the inner surface of the stepped hole 453, multiple edges of the bolt are stuck by two adjacent strip teeth 454. When the screwing base body 451 is driven by the T-shaped cylinder 42 to rotate, multiple edges of the bolt can be driven to rotate together.

[0028] The clamping module 46 includes a rectangular sliding groove 461 and a clamping notch 462. The rectangular sliding groove 461 is provided at the right end of the outer surface of the T-shaped cylinder 42, and the clamping notch 462 is provided at the right end of the outer surface of the screwing base body 451. The positions of the rectangular sliding groove 461 and the clamping notch 462 correspond to each other. An elastic piece 463 is fixedly connected to the left side of the inner surface of the rectangular sliding groove 461. A clamping block 464 is fixedly connected to the side surface of the elastic piece 463 and near the clamping notch 462. When the screw 44 is tightened, not only can the screwing base body 451 be fixed to the T-shaped cylinder 42, making the screwing base body 451 not easy to loosen; There are three rectangular sliding grooves 461, and the three rectangular sliding grooves 461 are evenly distributed on the right end of the outer surface of the T-shaped cylinder 42. There are three clamping notches 462, and the three clamping notches 462 are evenly distributed on the right end of the outer surface of the screwing base body 451. The elastic piece 463 is set to be arc-shaped, which is convenient for deformation after receiving a thrust.

[0029] Meanwhile, the right end of the screw 44 can also apply a pushing force to the elastic piece 463. At this time, the elastic piece 463 is pressed and elastically deformed. At this time, the deformed elastic piece 463 pushes the clamping block 464 downward, and under the guiding action of the rectangular sliding groove 461, the clamping block 464 smoothly slides into the clamping notch 462. At this time, the clamping is completed, and the base body 451 will not shake when it is rotated.

[0030] The second embodiment is as follows Figures 1 - 7 shown, based on the first embodiment: A heat dissipation component 5, which has an annular guide rail 51 fixedly connected to the inner surface of the housing 1 and close to the position of the T-shaped cylinder 42, and the T-shaped cylinder 42 passes through the center position of the annular guide rail 51. The inner surface of the annular guide rail 51 is slidably connected with a rotating ring 52, and a blade 53 is fixedly connected to the inner surface of the rotating ring 52 and close to the position of the lever 47. The blade 53 is inclined. When the T-shaped cylinder 42 is driven to rotate, at this time, the lever 47 will rotate together, and the lever 47 contacts the blade 53. Combining with the fact that the rotating ring 52 can rotate under the guidance of the annular guide rail 51, and with the continuous rotation of the lever 47, the blade 53 is pushed to rotate circumferentially. At this time, the rotating blade 53 can fan the air inside the housing 1, so that the air is discharged from the round hole 9, thereby forming an air flow. At this time, by using the flow of the gas, the heat inside the housing 1 can be dissipated in time.

[0031] A rotating groove adapted to the rotating ring 52 is provided on the inner surface of the annular guide rail 51 to facilitate the rotation of the rotating ring 52. Six blades 53 are provided, and the six blades 53 are evenly distributed on the inner surface of the rotating ring 52.

[0032] The third embodiment is as follows Figures 6 - 8 shown, based on the second embodiment: An auxiliary module 10 is arranged inside the shell 1 and near the right end. The auxiliary module 10 includes a supporting square column 101. The top of the supporting square column 101 is fixedly connected to the inner surface of the shell 1. The end of the supporting square column 101 away from the inner surface of the shell 1 is fixedly connected to a conical bucket 102. The inner surface of the conical bucket 102 is fixedly connected to a spiral sheet 103. The inner surface of the conical bucket 102 and near the left end is fixedly connected to a round rod 104. The end of the round rod 104 away from the inner surface of the conical bucket 102 is fixedly connected to a universal ball 105. When the gas in the shell 1 is fanned by the blades 53 When blowing, the airflow enters the conical bucket 102, and under the guidance of the spiral blade 103, the airflow is made into a swirl state, and the aperture of the conical bucket 102 is gradually reduced from left to right. At this time, the airflow output space is reduced, and the gas flow rate is accelerated, thereby accelerating the heat out. At the same time, the left side of the universal ball 105 is in contact with the right end of the twisting base 451. At this time, the universal ball 105 supports the twisting base 451, and when the twisting base 451 rotates, the universal ball 105 can roll without hindering the rotation of the twisting base 451.

[0033] The spiral blades 103 are evenly distributed on the inner surface of the conical bucket 102, which facilitates the airflow to form a swirl. The aperture of the conical bucket 102 gradually decreases from left to right, which can speed up the gas flow.

[0034] When in use, the twisting module 45 is embedded in the T-shaped cylinder 42, and the twisting base 451 is fixed to the T-shaped cylinder 42 by the screw 44. At this time, the right end of the screw 44 extends out and applies a pushing force to the elastic sheet 463. At this time, the elastic sheet 463 is pressed to elastically deform. At this time, the deformed elastic sheet 463 pushes the clamping block 464 downward, and under the guidance of the rectangular slide groove 461, the clamping block 464 slides smoothly into the clamping notch 462. At this time, the clamping is completed, and the twisting base 451 will not shake; At this time, the left end of the screw base 451 is pressed against the end of the bolt, and the end of the bolt is embedded in the stepped hole 453. At this time, two adjacent bar teeth 454 are stuck at the corner position of the end of the bolt, and the bar teeth 454 are evenly distributed on the inner surface of the stepped hole 453, so that multiple corners of the bolt are stuck by the two adjacent bar teeth 454, and the output end of the motor 2 is used to drive the disc gear 3 to rotate, and combined with the meshing connection between the disc gear 3 and the annular gear ring 43, the annular connector 41 and the housing 1 are in a rotational connection at this time, so that the T-shaped cylinder 42 is driven to rotate, and then the screwing module 45 will rotate together, so that the screwing base 451 can be driven by the T-shaped cylinder 42 to rotate, so that multiple corners of the bolt are driven to rotate together, and the bolt can be disassembled and installed; And as the lever 47 is driven to rotate, and with the continuous rotation of the lever 47, the blade 53 is pushed to rotate in a circle. At this time, the rotating blade 53 can fan the air in the housing 1, so that the air is discharged from the round hole 9, thereby forming an air circulation. At this time, by using the flow of the gas, the heat inside the housing 1 can be dissipated in time; Moreover, when the gas in the housing 1 is fanned and blown by the blade 53, the air flow enters the conical hopper 102 at this time, and under the guidance of the spiral blade 103, the air flow is in a swirling state. Since the conical hopper 102 is conical, the air flow output space is reduced, and at this time the gas flow rate is accelerated, thereby accelerating the heat removal. At the same time, the left side of the universal ball 105 is in contact with the right end of the screwing base 451. At this time, the universal ball 105 supports the screwing base 451, and when the screwing base 451 rotates, the universal ball 105 can roll without hindering the rotation of the screwing base 451, making the rotation of the screwing base 451 smoother.
