[0040] The accompanying drawings show various structural schematic diagrams of the embodiments disclosed in the utility model. These figures are not drawn to scale, and some details are magnified and some details may be omitted for the purpose of clear expression. The shapes of various regions and layers shown in the figures and the relative sizes and positional relationships therebetween are only exemplary, and may deviate in practice due to manufacturing tolerances or technical limitations, and those skilled in the art may additionally design regions / layers with different shapes, sizes, and relative positions according to actual needs.

[0041] like Figures 1 to 4 As shown, the first embodiment of the utility model discloses a dynamic sheet metal repair device, which includes a driving component 10, a fixed component 20 and a movable component 30. The fixed component 20 and the movable component 30 are connected to the driving component 10, and the movable component 30 can be linearly extended and retracted in the horizontal or vertical direction relative to the fixed component 20.

[0042] The driving assembly 10 includes a control switch 11, a power source 12, a power transmission member 13, a reduction group 14 and a movable group 15. The control switch 11 is electrically connected to the power source 12. The power source 12 can be turned on or off to start or stop outputting power by operating the control switch 11. The power source 12 can be a power source driven by electricity, air pressure or hydraulic pressure, such as a battery, a pneumatic cylinder, a hydraulic cylinder and the like.

[0043] In this embodiment, the power source 12 is a battery that mainly outputs power and can be set as a replaceable battery or a non-replaceable rechargeable battery as needed. When the control switch 11 is connected to the power source 12, the power source 12 can start outputting power or stop outputting power by pressing or switching the switch.

[0044] The power transmission component 13 is connected to the power source 12. In this embodiment, the power transmission component 13 is an electric motor, which can be driven by the power provided by the power source 12. The power transmission component 13 can also adjust the power transmission options according to the different power sources of the power source 12. For example, if air pressure is input, a pneumatic motor can be used, and if hydraulic pressure is input, a hydraulic motor can be used. Different options are not limited in this embodiment.

[0045] The reduction group 14 is connected to the power transmission member 13. After the power transmitted by the power transmission member 13 enters the reduction group 14, the various arrangements of the reduction gear groups in the reduction group 14 can achieve the effect of reducing the rotation speed and increasing the torque. The reduction group 14 can be purchased and selected according to user needs, and this embodiment is not limited thereto. The reduction group 14 can also be selected and set according to needs. When the power and rotation speed transmitted and output by the power transmission member 13 can be controlled, the reduction group 14 can also be selected not to be set.

[0046] The movable group 15 is connected to the reduction group 14, and the power output by the reduction group 14 drives the movable group 15 to move. In this embodiment, the movable group 15 adopts a combination of a linear screw 151 and a movable screw seat 152. A stopper 153 is provided at the end of the linear screw 151 that is different from the end connected to the reduction group 14. After the linear screw 151 of the movable group 15 is connected to the output gear in the reduction group 14, it can be rotated. The movable screw seat 152 can generate displacement along the thread on the linear screw 151 by limiting the rotation, and can drive the movable component 30 to linearly telescope relative to the fixed component 20 in the horizontal or vertical direction.

[0047] The active group 15 is a mechanism that is actuated by the torque output by the reduction group 14 and outputs actuation in a linear direction, wherein the active group 15 can also be a combination of different output power such as a belt and a pulley, a chain and a gear, a steel belt and a pulley, a steel wire and a wire wheel, a connecting rod group, a rocker or a swing arm, or a gear and a rack. The examples given in this embodiment are only preferred examples and are not intended to be a narrow interpretation of the scope covered by the term active group 15.

[0048] If the reduction group 14 is not provided, the movable group 15 can be directly connected to the power transmission member 13 according to different requirements to reduce the complexity of the overall setting.

[0049] Preferably, in this embodiment, the control switch 11 and the power source 12 of the driving component 10 are connected to each other, the power transmission component 13 and the reduction group 14 are coaxially arranged horizontally, and the two are assembled in the same housing 16, and the power transmission component 13 is electrically connected to the power source 12, and the power transmission component 13 can be driven by the power source 12 to transmit power to the reduction group 14, and the movable group 15 is arranged on the inner side of the fixed component 20.

[0050] It should be noted that the various parts contained in the drive assembly 10 are all ready-made components and may have independent or separate housings, but are combined into a whole by assembly. The drive assembly 10 is assembled with commonly used parts. For example, the control switch 11 uses the current push button switch, and the power source used by the power source 12, such as batteries, pneumatic cylinders, hydraulic cylinders, etc., can be purchased and assembled by purchasing ready-made parts. The power transmission part 13 is also a purchased ready-made electric motor, the reduction group 14 is a ready-made reduction gear mechanism, and the movable group 15 uses a ready-made screw assembly. The interior of the drive assembly 10 includes but is not limited to the aforementioned description. Specifically, the most important thing about the drive assembly 10 is that it provides the movable assembly 30 with the ability to actuate, so that the movable assembly 30 can move linearly relative to the fixed assembly 20. The specific activity or connection settings can be adjusted according to user needs, and the positions of the aforementioned parts can also be adjusted according to user needs.

[0051] The fixing assembly 20 is connected to the driving assembly 10 and includes an outer sleeve 21 , an inner sleeve 22 , a track 23 and a first tool connecting seat 24 .

[0052] The outer sleeve 21 is connected to the housing 16 of the driving assembly 10 and is sleeved on the outside of the movable group 15 . An active cavity 210 is formed on the inner side of the outer sleeve 21 , and the movable assembly 30 can slide linearly in the active cavity 210 .

[0053] The inner sleeve 22 is arranged in the movable cavity 210 of the outer sleeve 21 and is connected to the inside of the outer sleeve 21. The inner sleeve 22 is sleeved on the outside of the movable group 15, and a spring abutment portion 221 is formed at the end connected to the outer sleeve 21 for mounting one end of the spring.

[0054] The track 23 is arranged on one side of the outer sleeve 21 and the outer shell 16, and a positioning portion 231 is formed on the track 23. The positioning portion 231 is linearly arranged along the track 23 and presents a tooth shape. The track 23 can be fixed on the outer sleeve 21 or detachably arranged on the outer sleeve 21, which is not limited in this embodiment.

[0055] The first tool connection seat 24 is detachably and movably arranged on the track 23, and includes a movable seat 241, a clamping block 242 and an adjusting member 243. The movable seat 241 can be further connected to different drawing heads or components fixed on the sheet metal, and is connected in various replaceable ways such as bolts, latches, buckles or bonding. When the movable seat 241 reaches the end of its service life and cannot be used any more, the movable seat 241 can also be continuously replaced. The movable seat 241 is provided with a matching clamping tooth corresponding to the side surface of the track 23, so that the movable seat 241 can be clamped with the positioning portion 231 of the track 23, and after being clamped, the movable seat 241 can be temporarily fixed to the track 23;

[0056] The block 242 is arranged on the inner side of the track 23, and the adjusting member 243 passes through the movable seat 241 and is screwed on the block 242. The gap between the movable seat 241 and the block 242 can be controlled by the tightness of the adjusting member 243 and the movable seat 241. When the gap between the movable seat 241 and the block 242 is large enough, the movable seat 241 can be displaced along the track 23, otherwise, the movable seat 241 cannot move, thereby achieving the effect of adjusting the position.

[0057] The first tool connection base 24 includes but is not limited to adjusting the position with respect to the track 23 by the bolt adjustment method mentioned above, and can also achieve the effect of displacing the first tool connection base 24 relative to the track 23 by different methods such as snapping, pressing, toggling, and rotating.

[0058] The movable component 30 can move relative to the fixed component 20 and can perform linear telescopic motion along the axis of the fixed component 20 .

[0059] The movable assembly 30 includes a movable shaft 31 , a second tool connection seat 32 , an outer guide tube 33 , an inner guide tube 34 and a spring 35 .

[0060] Among them, the moving shaft 31 of the movable component 30 is a hollow shaft tube. The movable component 30 is sleeved on the linear screw 151 of the movable group 15 with the moving shaft 31, and abuts against the moving screw seat 152 of the movable group 15. When the linear screw 151 rotates, the moving screw seat 152 will move along the rotation direction of the linear screw 151, thereby pushing the moving shaft 31 to move along the rotation direction of the linear screw 151 until the moving screw seat 152 hits the block 153 to limit the movable stroke of the moving shaft 31.

[0061] The second tool connecting seat 32 is connected to the end of the moving shaft 31 extending out of the inner sleeve 22, and includes a connecting portion 321 connected to the moving shaft 31 and a fixed seat 322 connected to the connecting portion 321. The connecting portion 321 is connected to the moving shaft 31 in a screw-locking manner and can be removed from the moving shaft 31 and replaced. The setting of the fixed seat 322 is roughly the same as the aforementioned movable seat 241. The fixed seat 322 can also be further connected to different pulling heads for drawing or components fixed on sheet metal, and connected in various ways such as bolts, pins, snaps or bonding. When it cannot be used, the fixed seat 322 can also be continuously replaced and disassembled.

[0062] Preferably, the fixed seat 322 is equiaxially arranged on the same axis as the movable seat 241. Specifically, the first tool connecting seat 24 and the second tool connecting seat 32 can be arranged on the same horizontal / vertical axis, which helps to adjust the recessed area on the same plane. Of course, it can also be adjusted according to different needs.

[0063] One end of the outer guide tube 33 is connected to the connecting portion 321 of the second tool connecting seat 32, and is arranged around the outside of the movable shaft 31, and is inserted into the inner side of the outer sleeve 21 of the fixing assembly 20 with the outer side. Preferably, the outer guide tube 33 can fit snugly on the inner side of the outer sleeve 21, so that the outer guide tube 33 can slide smoothly relative to the outer sleeve 21.

[0064] The inner tube 34 is connected to the inner side of the outer tube 33 and is arranged around the outer side of the movable shaft 31; the spring 35 is sleeved on the outer side of the inner sleeve 22 of the fixed component 20, and one end is respectively against the spring abutment portion 221 of the inner sleeve 22, and the other end is against the inner side of the inner tube 34. The inner tube 34 and the spring 35 can be set according to needs, mainly to provide initial elastic force to the movable component 30 for reset action. When no external force is applied, the elastic force can be generated by the spring 35, and the movable component 30 will not be over-compressed when initially subjected to force, thereby avoiding damage to the movable group 15.

[0065] like Figures 4 to 6 As shown, the method of using this embodiment is as follows. Figure 6For example, the first tool connection seat 24 and the second tool connection seat 32 can be further connected to a pulling member 40. The user respectively fixes the first tool connection seat 24 of the fixed component 20 and the second tool connection seat 32 of the movable component 30 on the object to be adjusted or pulled through the pulling member 40. There are many choices of the pulling member 40, which are not listed in detail in the utility model. After the utility model is fixed, by pressing the control switch 11 of the driving component 10, the power source 12 further generates electricity and outputs it to the power transmission component 13 and the reduction group 14 to drive the movable group 15 to operate. When the movable group 15 is activated, it further drives the moving shaft 31 of the movable component 30, so that the second tool connection seat 32 can be driven to the specified position. In the whole process, it is driven by electricity, and does not require manpower to drive, which can save a lot of manpower.

[0066] In addition, if the distance between the second tool connecting base 32 and the first tool connecting base 24 is not applicable, the first tool connecting base 24 can be further adjusted to move on the track 23 to the appropriate distance to be adjusted, or by adjusting the distance of the movable group 15. Either or both can be used at the same time to add a lot of flexibility to the adjustment / restoration operation.

[0067] In addition, the device of the utility model is easy to carry, has a very small size, can be driven without installing a large machine or providing a large amount of power, and is energy-saving and labor-saving.

[0068] like Figures 7 to 10 This is another embodiment of the utility model, wherein the difference from the aforementioned embodiment is that the positional configuration of the driving component 10A, the fixed component 20A and the movable component 30A is changed. The driving component 10A includes the same components, and only the connection position is adjusted. The connection method of the driving component 10A is sequentially a power source 12A, a control switch 11A, a power transmission component 13A, a reduction group 14A and a movable group 15A. Through different position adjustments and component settings, the overall volume of the driving component 10A of this embodiment can be reduced. The positions of the power transmission component 13A and the reduction group 14A, which originally constitute duplicate positions, are adjusted, and the internal structure is also replaced. The power transmission component 13A is coaxially arranged with the control switch 11A and the power source 12A, and the gears inside the reduction group 14A are changed to a vertical connection setting, which can save the horizontal volume of the overall equipment.

[0069] In the fixed component 20A, only the design of the outer sleeve 21, the track 23 and the first tool connecting seat 24 is retained; in the movable component 30A, only the design of the movable shaft 31 and the second tool connecting seat 32 is retained; the overall design is more simple, focusing on the reasonable component structure configuration, and can produce the same function and design.

[0070] like Fig.11 Another embodiment is shown, in which the moving shaft 31B of the movable component 30B can be designed to be retractable. The moving shaft 31B is stepped and has multiple sleeves with different diameters. Through the design of the parts inside the driving component, the moving shaft 31B can continue to extend forward / contract backward after extending a fixed distance, and can extend / contract multiple sections at most. Through such a design, in addition to shortening the length of the moving shaft 31B itself, the fixed component and the movable component can benefit from the length of the moving shaft 31B, thereby reducing its volume, making it more convenient to carry.

[0071] If the overall weight of the present invention is relatively heavy, an auxiliary lifting device / adsorption device may be installed on the horizontal side along the axial direction of the fixing component to reduce the overall weight when moving.

[0072] Therefore, the driving components 10 and 10A of the two preferred embodiments of the present invention are only examples. The technology disclosed in the present invention mainly focuses on the linear displacement generated by the driving component, thereby driving a device having a second tool connecting seat and a first tool connecting seat, and driving a sheet metal repair equipment that produces a linear pulling / pulling effect through an external power source. Therefore, the concept of the driving component proposed in the present invention can achieve the effect of saving manpower through the basic configuration principle of energy → power output → power conversion.

[0073] Therefore, all parts in the driving assembly of the utility model are existing technologies and can be adjusted and replaced into the same technical effects with linear displacement according to different needs. Other inventions that only change the configuration or adjust the number of parts cannot exceed the concept disclosed by the utility model.

[0074] The improved effect of the utility model has the following characteristics:

[0075] 1. The power source of the driving assembly of the utility model can be driven by electricity, air pressure or hydraulic pressure to further drive the movable parts of the driving assembly and cause the movable assembly to relatively produce linear displacement. By driving the movable assembly with external power, the problem of inconsistent force and insufficient adjustment accuracy of existing manual adjustment can be improved.

[0076] 2. The driving assembly of the utility model is provided with devices such as power transmission parts and reduction groups. When the power of the driving assembly is transmitted to the movable assembly through the power transmission parts and the reduction group, it can be positioned and force applied more accurately without relying on traditional manpower adjustment. When repairing sheet metal, the force and the position of action can also be accurately adjusted.

[0077] 3. The fixing assembly of the utility model further combines a track with adjustable position and a first tool connection seat. The first tool connection seat can be adjusted arbitrarily according to the user's usage habits and the range of force required, without being limited to a fixed size range, thereby greatly improving the flexibility of operation.

[0078] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
