[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0021] During the production process of the car body, some process holes need to be opened. The existence of the process holes causes the passenger compartment to be connected to the outside world, and the plug cap 400 needs to be used to seal the process holes to ensure the sealing of the car body. At present, the installation method of the plug cap 400 is mostly manual pressing operation. Workers need to pick up the corresponding plug cap 400 and install it in the hole position. The operation is time-consuming and laborious. Workers will also become fatigued after long-term operation, resulting in the risk of improper installation of the plug cap 400. At present, there are few automated installation methods, and the existing installation tools have many problems, such as the large size of the tools, which cannot adapt to relatively small spaces, low degree of automation, and difficult operation and installation. like Figure 1 As shown, the vehicle body cover installation tool of the present invention includes a storage module 100 , a power assist module 200 and a position limiting guide module 300 .

[0022] The storage module 100 includes a casing 110 and a piston 120. The casing 110 is a hollow cylindrical structure. The casing 110 of this embodiment is extended forward and backward. In some other embodiments, the casing 110 may extend in other directions. In order to facilitate the description of other components, this embodiment takes the casing 110 extending forward and backward as an example.

[0023] The piston 120 is installed in the casing 110 for forward and backward sliding. The front end surface of the piston 120 and the inner wall of the casing 110 form a storage cavity 130. The notch of the storage cavity 130 is set forward. The storage cavity 130 is used to store multiple plugging covers 400 stacked in sequence.

[0024] The power-assisting module 200 includes an outer shell 210 and a power-assisting driving mechanism 220. The outer shell 210 is connected to the rear end of the sleeve shell 110. The power-assisting driving mechanism 220 is arranged in the outer shell 210. The power-assisting driving mechanism 220 is provided with a power-assisting driving end 221 driven forward and backward. The power-assisting driving end 221 is used to abut against the rear end surface of the piston 120 to push the piston 120 to move in the sleeve shell 110 along the forward and backward direction.

[0025] like Figure 2 The limiting guide module 300 includes a control component, a limiting component and a guiding component. The limiting component includes at least one limiting block 310 located at the notch of the storage cavity slot 130. The limiting block 310 is used to abut against the front end surface of the plugging cover 400 at the notch of the storage cavity slot 130 and limit it. It can be understood that the limiting block 310 limits the frontmost plugging cover 400 at the notch of the storage cavity slot 130, so that multiple plugging covers 400 are limited and stored in the storage cavity slot 130 and clamped between the power-assisted pushing end 221 and the limiting block 310.

[0026] like Figure 4As shown, the guide assembly includes at least two guide blocks 320 annularly spaced apart at the notch of the storage cavity groove 130, the guide blocks 320 are soft components, and the outer peripheral walls of all the guide blocks 320 together form a guide conical structure coaxially arranged with the storage cavity groove 130, the notch of the storage cavity groove 130, the limit block 310 and the guide block 320 are arranged in sequence from back to front along the axial direction, and the control assembly is used to control the radial movement of the guide block 320 along the storage cavity groove 130, and to control the limit block 310 to be set within or outside the axial range of the storage cavity groove 130.

[0027] When the process hole is blocked, the present invention forms a guide cone structure coaxially arranged with the storage cavity groove 130 through the outer peripheral wall of all the guide blocks 320 to match the process hole, so that the plugging cover 400 in the storage cavity groove 130 is coaxially aligned with the process hole, and the guide block 320 can be controlled by the control component to move radially along the storage cavity groove 130 according to the aperture of the process hole to adjust the size of the guide cone structure and move the soft guide block 320 out of the process hole. The limit block 310 is controlled to be within or outside the axial range of the storage cavity groove 130 to limit and release the limit of the plugging cover 400 in the storage cavity groove 130, and the plugging cover 400 is pushed out by the power-assisted pushing mechanism 220 to accurately install and block the process hole. The present invention does not need to align the process hole by visual means, has a guiding function, and improves the accuracy of installation.

[0028] like Figure 3 and Figure 4 As shown, the guide assembly of this embodiment also includes at least two guide rods 330 extending radially along the storage cavity groove 130, a guide frame 111 is provided on the outer side of the shell 110, the guide rod 330 is radially slidably installed on the guide frame 111, the guide block 320 is installed on the front side of the inner end of the guide rod 330, the control assembly is connected to the guide rod 330 by transmission, the control assembly drives the guide rod 330 to move radially along the storage cavity groove 130, so as to drive the guide block 320 to move radially, wherein the guide block 320 of this embodiment is made of soft sponge, and the cross-section of the guide block 320 is triangular.

[0029] like Figure 2 and Figure 5 As shown, the control component of this embodiment includes at least two rotating shafts 340 axially oriented with the storage cavity groove 130. The rotating shafts 340 are rotatably installed on the outer side of the shell 110, and the limit blocks 310 are installed on the outer periphery of the rotating shafts 340. This embodiment drives the limit blocks 310 by the rotatable rotating shafts 340, so that the limit blocks 310 can be rotated within or outside the axial range of the storage cavity groove 130 to achieve limiting and releasing the blocking cover 400. It can be understood that the limit blocks 310 are eccentrically installed on the rotating shaft 340.

[0030] Furthermore, if Figure 3 and Figure 5 As shown, the rotating shaft 340 is fixedly sleeved with a cam body 341 located on the outer end side of the guide rod 330, and a first elastic member 350 is provided between the guide rod 330 and the guide frame 111. The first elastic member 350 is used to push the guide rod 330 to move radially outward so that the outer end of the guide rod 330 slides and abuts against the outer peripheral cam surface of the cam body 341. When the rotating shaft 340 is rotated, the limit block 310 can be driven to rotate with it, and the cam body 341 can be used to push the guide rod 330 to move radially to achieve adjustment of the guide block 320.

[0031] Furthermore, in order to prevent the guide rod 330 from loosening, as Figure 4 As shown, in the embodiment of the present invention, magnetic blocks 360 are respectively disposed on the guide rod 330 and the guide frame 111 , and magnetic attraction is achieved by the two magnetic blocks 360 with opposite polarities attracting each other, so as to maintain the locking stability of the guide rod 330 .

[0032] In this embodiment, the first elastic member 350 is a spring, the guide rod 330 is a frame beam structure, the first elastic member 350 is radially sleeved in the guide rod 330 , and the two ends of the first elastic member 350 are respectively in contact with the guide rod 330 and the guide frame 111 .

[0033] Furthermore, in order to facilitate operation, Figure 1 , 2 As shown in Figure 5, the housing 210 is provided with a handle 211, and the control assembly includes a trigger frame 370 and at least two sliding sleeves 380. The trigger frame 370 is vertically arranged, and the middle part of the trigger frame 370 is hinged to the outside of the housing 210. The lower end of the trigger frame 370 is provided with a trigger body 371 arranged opposite to the handle 211. The sliding sleeve 380 is slidably installed on the outside of the housing 210 along the axial direction of the rotating shaft 340. The sliding sleeve 380 is slidably fitted with the rear end of the rotating shaft 340 along the axial direction. The outer periphery of the rotating shaft 340 is provided with a spiral groove 342, and the sliding sleeve 380 is provided with a limiting column 381 that slides with the spiral groove 342. The upper end of the trigger frame 370 is connected to the housing 210. The sliding sleeve 380 is transmission connected, and the upper part of the trigger frame 370 is fork-shaped. The upper part of the trigger frame 370 is transmission connected to the two sliding sleeves 380 respectively. The trigger frame 370 is used to drive the sliding sleeve 380 to move back and forth along the axial direction to drive the rotating shaft 340 to rotate. It can be understood that the sliding sleeve 380 can only slide along the front and rear directions but cannot rotate, and the rotating shaft 340 can only rotate but cannot move forward and backward. When the sliding sleeve 380 moves forward and backward, under the sliding cooperation of the limit column 381 and the spiral groove 342, the rotating shaft 340 rotates relative to the sliding sleeve 380, thereby driving the limit block 310 and the cam body 341 on the rotating shaft 340 to rotate.

[0034] During operation, the worker only needs to hold the handle 211 with one hand and pull the trigger body 371 to drive the trigger frame 370 to rotate. The trigger frame 370 drives the sliding sleeve 380 to move in the front-rear direction to drive the rotating shaft 340 to rotate, thereby controlling the limit block 310 and the guide block 320.

[0035] In order to achieve automatic reset, such as Figure 2 and Figure 5 As shown, in the embodiment of the present invention, a second elastic member 390 is provided between the sliding sleeve 380 and the rotating shaft 340. The second elastic member 390 is also a spring. The second elastic member 390 is extended forward and backward. The front end and the rear end of the second elastic member 390 are respectively in contact with the rotating shaft 340 and the sliding sleeve 380. The second elastic member 390 is used to push the sliding sleeve 380 and the rotating shaft 340 away from each other in the front and rear directions. It can be understood that when the trigger body 371 is pulled, the sliding sleeve 380 is driven to move forward. At this time, the second elastic member 390 is compressed. When the trigger body 371 is released, the sliding sleeve 380 moves backward under the action of the reset elastic force of the second elastic member 390, and the trigger body 371 returns to its original position.

[0036] The sleeve 110 of this embodiment is detachably connected to the outer shell 210, the sliding sleeve 380 is detachably fitted with the rotating shaft 340, and the outer periphery of the limiting column 381 is inserted into the sliding sleeve 380 to extend into the spiral groove 342. In actual use, storage modules 100 and limiting guide modules 300 of different sizes are selected according to the aperture size and assembled together for the installation of the blocking cover 400.

[0037] The sleeve 110 and the outer shell 210 of this embodiment adopt a snap-fit ​​structure to achieve a detachable connection, which is convenient for quick replacement when installing on a vehicle.

[0038] like Figure 1 As shown, a pressure sensor 222 is provided between the booster push end 221 and the piston 120 of this embodiment, and the booster module 200 is also provided with an indicator, which is connected to the pressure sensor 222 by signal. The pressure sensor 222 is used to detect the magnitude of the pressure value, so as to detect whether the pressure provided by the booster push end 221 meets the insertion force requirement of the plugging cover 400. When it does not meet the insertion force requirement of the plugging cover 400, the indicator sends a signal indicating non-compliance, and when it meets the insertion force requirement of the plugging cover 400, the indicator sends a signal indicating compliance. Thus, the embodiment of the present invention can detect the matching degree between the plugging cover 400 and the aperture and whether the plugging cover 400 is installed in place through the pressure sensor 222, thereby improving the installation accuracy.

[0039] The indicator of the embodiment of the present invention includes an indicator light 223, and the indicator light 223 can emit light of different colors according to different signals.

[0040] like Figure 1As shown, the power-assisting mechanism 220 of the embodiment of the present invention comprises a T-shaped force transmission frame 224 and a third elastic member 225. The third elastic member 225 acts between the force transmission frame 224 and the housing 210. The third elastic member 225 is used to push the force transmission frame 224 to abut against the rear end surface of the piston 120. The third elastic member 225 of this embodiment adopts a spring. The third elastic member 225 is arranged to extend forward and backward. The rear end and front end of the third elastic member 225 act on the inner wall of the housing 210 and the rear end of the force transmission frame 224 respectively, and the front end of the force transmission frame 224 is the power-assisting end 221. The power-assisting mechanism 220 of the embodiment of the present invention does not reciprocate, but moves linearly. The storage module 100 and the power-assisting module 200 are coaxially arranged, which reduces the volume and has higher applicability.

[0041] In order to avoid damage to the vehicle body, a sponge ring 112 is provided at the front edge of the cover 110 of the present embodiment, and the cover 110 can contact the vehicle body through the sponge ring 112 .

[0042] like Figure 6 As shown, the embodiment of the present invention also provides a method for using the vehicle body cover installation tool, and the method comprises the following steps: Step S100: stacking a plurality of blocking covers 400 in sequence and storing them in the storage cavity 130, and controlling the limiting block 310 to be set within the axial range of the storage cavity 130 to limit the blocking covers 400; Step S200: aligning the guide conical structures formed by the outer peripheral walls of all the guide blocks 320 with the process holes to be blocked, so that the blocking cover 400 in the storage cavity groove 130 is aligned with the process holes; Step S300: Control all guide blocks 320 to move outward along the radial direction of the storage cavity 130, and control the limiting block 310 to be set outside the axial range of the storage cavity 130 to release the limiting of the blocking cover 400; Step S400: Pushing out the plugging cover 400 through the power-assisted pushing mechanism 220 to install the outermost plugging cover 400 to seal the process hole; Step S500 : controlling the limiting block 310 to be disposed within the axial range of the storage cavity 130 , and re-limiting the blocking cover 400 in the storage cavity 130 .

[0043] In step 100 , firstly, storage modules 100 and position limiting guide modules 300 of different sizes are selected according to the aperture size, and the blocking covers 400 are stacked and stored in the storage cavity 130 in sequence.

[0044] In step S300, the trigger body 371 is pulled to drive the trigger frame 370 to rotate, and the trigger frame 370 drives the sliding sleeve 380 to move in the front-to-back direction to drive the rotating shaft 340 to rotate, so that all the guide blocks 320 move radially outward along the storage cavity groove 130, and the limit block 310 rotates to outside the axial range of the storage cavity groove 130.

[0045] In step S400, the pressure value is detected by the pressure sensor 222. If the pressure value meets the insertion force requirement of the plugging cover 400, the indicator light 223 is displayed in green, indicating that the plugging cover 400 matches the aperture. If the pressure sensor 222 detects that the pressure is too large or too small compared to the insertion force, the indicator light 223 is displayed in red, indicating that the plugging cover 400 does not match the aperture.

[0046] In step S500, the trigger body 371 is released, and the limit block 310 and the guide block 320 are reset to prepare for the next installation.

[0047] The vehicle body cover installation tool of the present invention can realize the installation and detection of the cover 400, improve the installation efficiency, reduce the labor intensity of workers, has a guiding function and a detection function, and improves the installation accuracy.
