Description

Technical Field

[0001] This utility model relates to the field of torque direction conversion technology, and in particular to a torque direction conversion device. Background Technology

[0002] During equipment installation, maintenance, and repair, it is often necessary to operate equipment with a turning structure, such as bolts inside the corresponding channel steel. These bolts are hidden in narrow spaces with special angles, and the conventional operating space is extremely limited.

[0003] Existing rotary force application devices, such as electric wrenches, have a single and fixed output torque direction. When facing the device to be turned in the above-mentioned special position, due to the limitations of the device's own structure and space, it is difficult for the electric wrench to be directly aligned and apply force. Even if it is forced to operate, it cannot guarantee the effective transmission of torque. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a torque direction conversion device. To achieve the above objective, this utility model adopts the following technical solution:

[0005] A torque direction conversion device includes a connecting mechanism for selectively fixing relative to a force output device to receive the force from it, and a force-applying mechanism perpendicular to and coupled to the axis of the connecting mechanism.

[0006] The connecting mechanism includes a connecting part connected to the force output device and a driving part coaxially disposed on the connecting part. The force applying mechanism includes a turning part for fixing relative to the device to be turned and a driven part coaxially disposed on the turning part. The driven part is configured to allow coupling with the driving part to receive the force from the driving part, so as to drive the turning part and the connecting part to move synchronously.

[0007] Furthermore, the device also includes a housing, which includes a base plate and a side plate disposed on the base plate and extending vertically upward. Through holes are respectively provided on the base plate and the side plate, so that the through holes can be used to accommodate the connecting part and the screwing part respectively, and allow the connecting part and the screwing part to rotate in the through holes respectively, so that the connecting mechanism and the force-applying mechanism are stably coupled together.

[0008] Furthermore, bearings are respectively fitted onto the connecting part and the screwing part in a relatively fixed manner, such that the bearings are respectively located in the through holes and are respectively fixed together with the bottom plate and the side plate.

[0009] Furthermore, the driving part and the driven part are configured as gears meshing together, and the axes of the driving part and the driven part are perpendicular to each other, so that the driven part can change the direction of the torque from the driving part.

[0010] Furthermore, the driving part and the driven part are configured as bevel gears meshing together, so that the meshing surfaces between the driving part and the driven part have uniform contact.

[0011] Furthermore, the device also includes a fixing plate sleeved on the bearing and fixed relative to the bearing, the fixing plate being configured to allow it to be fixed relative to the base plate and the side plate respectively, and to allow the bearing to be located within the through hole.

[0012] Furthermore, a plurality of helical fasteners are provided on the fixed plate, the helical fasteners being configured to allow connection with the housing to form a relative fixation between the fixed plate and the housing.

[0013] Furthermore, the side plates surround and are perpendicular to the bottom plate. The housing also includes a cover plate for covering the opening formed by the side plates, so that the bottom plate, side plates, and cover plate together form a cavity, and allow the driving part and the driven part to be disposed in the cavity.

[0014] Furthermore, the force-applying mechanism is configured as two, and is distributed on the side plate in a corresponding manner.

[0015] Furthermore, the connecting part includes a connecting shaft and a sleeve fixed to the connecting shaft, the sleeve being polygonal in shape for fastening to the force output device.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention includes a connecting mechanism for selectively fixing a force output device to receive the force from it, and a force-applying mechanism perpendicular to and coupled to the axis of the connecting mechanism. The connecting mechanism includes a connecting part connected to the force output device and a driving part coaxially mounted on the connecting part. The force-applying mechanism includes a turning part fixed to the device to be turned and a driven part coaxially mounted on the turning part. The driven part is configured to couple with the driving part to receive the force from the driving part, thereby driving the turning part and the connecting part to move synchronously. In this way, the torque output by the force output device can be stably and effectively transmitted to the device to be turned. This changes the previous situation where space constraints prevented effective torque transmission, ensuring the torque required for turning operations. Attached Figure Description

Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] To better understand the purpose, structure, and function of this utility model, the following detailed description of a torque direction conversion device is provided in conjunction with the accompanying drawings.

[0025] Figure 1 The schematic diagram illustrates the overall structure of the torque direction conversion device according to this utility model. In such a way... Figure 1 In the illustrated embodiment, the torque direction conversion device 100 includes a connecting mechanism 1. In this embodiment, the connecting mechanism 1 is configured to allow a force output device (not shown) to be selectively fixed relative to it to receive the force from the force output device.

[0026] At the same time, such as Figure 1 As shown, the device 100 further includes a force-applying mechanism 2 for selectively fixing relative to the device to be screwed (shown in the figure). In this embodiment, the force-applying mechanism 2 is configured to be perpendicular to the axis of the connecting mechanism 1 and coupled to the connecting mechanism 1 to receive the force from the connecting mechanism 1 and transmit it to the device to be screwed after changing the direction of the force.

[0027] In this configuration, when the device 100 is needed to tighten the equipment, the connecting mechanism 1 is first fixed to the force output device. Simultaneously, the force application mechanism 2 is fixed to the equipment to be tightened. This completes the arrangement of the device 100.

[0028] At this point, the force output device is activated. During this process, the force output device transmits the force to the connecting mechanism 1, and then to the force-applying mechanism 2, thereby driving the force-applying mechanism 2 to operate. In this process, the force-applying mechanism 2 will drive the device to be turned to operate synchronously. Thus, the turning operation of the device to be turned is realized.

[0029] It should be noted that the force output device can be any mechanism capable of applying rotational force, including but not limited to an electric wrench. The device to be tightened can be any mechanism with a bend, including but not limited to bolts inside a corresponding channel steel. However, the structure, working principle, and usage of electric wrenches and channel steel are well known to those skilled in the art.

[0030] In one embodiment, such as Figure 2 As shown, the connecting mechanism 1 includes a connecting part 11, which is configured to allow a force output device (not shown) to be coaxially connected to it. The connecting mechanism 1 also includes a driving part 12, which is coaxially arranged with the connecting part 11 and sleeved on the connecting part 11.

[0031] In addition, such as Figure 2 As shown, the force-applying mechanism 2 includes a screwing part 21, which is configured to allow coaxial connection with the device to be screwed (not shown in the figure). The force-applying mechanism 2 also includes a driven part 22, which is coaxially arranged with the screwing part 21 and sleeved on the screwing part 21.

[0032] In this embodiment, as Figure 2 As shown, the driven part 22 is configured to couple with the driving part 12, and the axes of the driven part 22 and the driving part 12 are perpendicular to each other. In this way, the driven part 22 can receive the force from the driving part 12, and after changing the direction of the force from the driving part 12 to a perpendicular direction, transmit it to the screwing part 21, thereby driving the screwing part 21 to move synchronously with the connecting part 11.

[0033] In this configuration, when the device 100 is needed to tighten the equipment, the connecting part 11 is first fixed to the force output device. Simultaneously, the tightening part 21 is fixed to the equipment to be tightened, and the axes of the tightening part 21 and the driven part 22 are coupled perpendicularly to each other. This completes the arrangement of the device 100.

[0034] Then, the force output device is activated. During this process, the force output device applies a force to the connecting part 11, thereby causing the connecting part 11 to rotate. In this process, the connecting part 11 drives the driving part 12 to rotate synchronously with it, thereby causing the driving part 12 to drive the driven part 22 to rotate synchronously with it, and in turn, causing the driven part 22 to drive the tightening part 21 to rotate synchronously. In this configuration, the tightening part 21 drives the device to be tightened to rotate, thereby realizing the tightening operation of the device to be tightened.

[0035] In one embodiment, such as Figure 3 As shown, the device 100 also includes a housing 3, which includes a base plate 31 and a side plate 32 disposed on the base plate 31 and extending vertically upward. Through holes 33 are respectively provided on the base plate 31 and the side plate 32, allowing the connecting part 11 and the screwing part 21 to be accommodated respectively, and allowing the connecting part 11 and the screwing part 21 to rotate within the through holes 33. In this way, the connecting mechanism 1 and the force-applying mechanism 2 can be stably coupled together, enabling the connecting mechanism 1 to stably output force towards the force-applying mechanism 2, thereby stably screwing the device to be screwed.

[0036] In one embodiment, such as Figure 2 As shown, bearings 4 are respectively fitted onto the connecting part 11 and the screwing part 21 in a relatively fixed manner, and the bearings 4 are respectively located in the through hole 33 and fixed to the base plate 31 and the side plate 32 respectively. This arrangement reduces the friction between the connecting part 11 and the screwing part 21 and the through hole 33 when they rotate along the through hole 33, allowing the connecting part 11 and the screwing part 21 to rotate smoothly. This also reduces the power consumption of the device 100.

[0037] In one embodiment, such as Figure 2 As shown, the driving part 12 and the driven part 22 are configured as meshing gears, and their axes are perpendicular to each other. This allows the driving part 12 to stably transmit force to the driven part 22 during rotation, continuously driving the driven part 22 to operate. Simultaneously, it also allows the driven part 22 to change the direction of the force from the driving part 12.

[0038] According to a preferred embodiment of the present invention, such as Figure 2 As shown, the driving part 12 and the driven part 22 are configured as bevel gears meshing together. This arrangement ensures uniform contact between the meshing surfaces of the driving part 12 and the driven part 22, thereby reducing localized stress concentration. This extends the service life of the device 100.

[0039] In one embodiment, such as Figure 1 As shown, the device 100 also includes a fixing plate 5 sleeved on and fixedly attached to the bearing 4. The fixing plate 5 is configured to allow it to be fixedly attached to the base plate 31 and the side plate 32 respectively, and to allow the bearing 4 to be located within the through hole 33. In this way, when it is necessary to remove the driving part 12 and the driven part 22 from the through hole 33, it is only necessary to disengage the fixing plate 5 from the base plate 31 and the side plate 32 respectively, thereby enabling the removal of the driving part 12 and the driven part 22. This facilitates the maintenance of the device 100.

[0040] According to a preferred embodiment of the present invention, such as Figure 1 As shown, a plurality of helical fasteners 51 are provided on the fixing plate 5. The helical fasteners 51 are configured to allow connection with the housing 3, so that the fixing plate 5 and the housing 3 are relatively fixed. In this way, when it is necessary to remove the fixing plate 5 from the housing 3, a force is applied to each helical fastener 51, thereby causing the helical fasteners 51 to disengage from the housing 3.

[0041] In one embodiment, such as Figure 3 As shown, the side plates 32 surround and are perpendicular to the bottom plate 31. The housing 3 also includes a cover plate 34 for covering the opening formed by the side plates 32. In this way, the bottom plate 31, side plates 32, and cover plate 34 together form a cavity 35, allowing the driving part 12 and the driven part 22 to be disposed within the cavity 35. In this way, the housing 3 can protect the driving part 12 and the driven part 22.

[0042] According to a preferred embodiment of the present invention, such as Figure 2 As shown, two force-applying mechanisms 2 are configured and distributed on the side plate 32 in a corresponding manner. This allows the connecting mechanism 1 to drive the two force-applying mechanisms 2 to move synchronously. Therefore, the working efficiency of the device 100 can be improved.

[0043] According to a preferred embodiment of the present invention, such as Figure 2As shown, the connecting part 11 includes a connecting shaft 111 fixedly together with the driving part 12, and a sleeve 112 fixedly together with the connecting shaft 111. The sleeve 112 is polygonal in shape and is used to connect to the force output device in a fastening manner. In this way, the frictional force generated between the sleeve 112 and the force output device can be increased, thereby enabling the connecting part 11 and the force output device to be connected more stably.

[0044] The operation of the torque direction conversion device 100 according to this utility model is as follows.

[0045] First, the sleeve 112 is fixed relative to the force output device (not shown in the figure). At the same time, the screwing part 21 is fixed relative to the device to be screwed (not shown in the figure). Thus, the arrangement of the device 100 is completed.

[0046] Then, the force output device is activated. During this process, the force output device applies a force to the sleeve 112, causing the connecting shaft 111 and the sleeve 112 to rotate synchronously. In this process, the connecting shaft 111 drives the drive unit 12 to rotate synchronously, which in turn drives the driven unit 22 to rotate synchronously, and the driven unit 22 then drives the tightening unit 21 to rotate synchronously. In this configuration, the tightening unit 21 drives the device to be tightened to rotate, thus achieving the tightening operation of the device.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
