Figure 2 is Figure 1 is a disassembled structural schematic view of the auxiliary tool shown in Figure 3 is Figure 1 is a structural schematic view of the lifting device shown in

[0033] The auxiliary tool 1 comprises a profiling device 10 and a lifting device 20. The profiling device 10 comprises a profiling fixing assembly 100, which is used to fix the workpiece to be installed 2. The lifting device 20 comprises a guide cylinder 210 and a screw column 220. The guide cylinder 210 is provided with a screw hole extending in the lifting direction Z. The screw column 220 is arranged to extend in the lifting direction Z. The profiling fixing assembly 100 is connected with the screw column 220. The screw column 220 is used to move in the screw hole to drive the profiling fixing assembly 100 to move in the lifting direction Z.

[0034] The profiling device 10 comprises a profiling fixing assembly 100, which can fix the workpiece to be installed 2 to avoid shaking of the workpiece to be installed 2. The end of the workpiece to be installed 2 away from the profiling device 10 is provided with a bolt, and a guide pin can be sleeved on the bolt, so as to facilitate positioning the workpiece to be installed 2 and the vehicle body by the guide pin.

[0035] The lifting device 20 is fixed with the profiling device 10, and the profiling device 10 can be lifted. The lifting device 20 comprises a guide cylinder 210 and a threaded column 220, the outer side of the threaded column 220 is provided with a thread, the guide cylinder 210 is provided with a threaded hole in rotation connection with the threaded column 220, and the threaded column 220 is inserted into the inside of the guide cylinder 210 through the threaded hole. The guide cylinder 210 can move in the lifting direction Z, so that the guide cylinder 210 can drive the profiling device 10 to move in the lifting direction Z through the threaded column 220, so that the workpiece 2 to be installed can move in the lifting direction Z. In addition, the threaded column 220 is also screwed with the guide cylinder 210, so that the height of the profiling device 10 can be adjusted by rotating the threaded column 220.

[0036] Through the above embodiment, the workpiece 2 to be installed is fixed to the profiling fixing assembly 100, one end of the threaded column 220 is connected with the profiling fixing assembly 100, and the threaded column 220 can also slide in the lifting direction Z in the guide cylinder 210 through the threaded hole, so that the guide cylinder 210 drives the profiling fixing assembly 100 to move in the lifting direction Z, and the threaded hole cooperates with the threaded column 220, so that the height of the profiling device 10 can be adjusted, which is suitable for different installation height requirements, so as to facilitate the installation of the workpiece 2 to be installed and improve the installation efficiency.

[0037] In some embodiments, the guide cylinder 210 comprises a main cylinder part 211 and an extension cylinder part 212, the extension cylinder part 212 is fixed to one end of the main cylinder part 211 close to the profiling fixing assembly 100, and the extension cylinder part 212 is screwed on the outer side of the threaded column 220. The threaded column 220 can be in sliding connection with the inner wall of the main cylinder part 211, the extension cylinder part 212 is located at one end of the main cylinder part 211 close to the profiling device 10, the extension cylinder part 212 can be in fixed connection with the main cylinder part 211, and the extension cylinder part 212 can be screwed with the threaded column 220, so that the threaded column 220 drives the profiling device 10 to rotate around the axis of the threaded column 220, and the relative position of the profiling device 10 and the extension cylinder part 212 can be adjusted, so as to increase or decrease the stroke range of the workpiece 2 to be installed. In addition, the extension cylinder part 212 is also screwed with the threaded column 220, so as to increase the screwing area of the threaded column 220 and the guide cylinder 210, and the friction force at the screwing position is larger when the profiling device 10 is rotated, so as to increase the damping when the threaded column 220 rotates, so that the threaded column 220 can rotate more subtly, so as to more accurately align the workpiece 2 to be installed with the vehicle body. The increase of the screwing area can also reduce the risk of deformation of the screwing position of the main cylinder part 211 and the threaded column 220.

[0038] In some embodiments, the lifting device 20 includes a lifting base 230 and a guide post 231. One end of the guide post 231 is connected to the lifting base 230, and the other end of the guide post 231 extends along the lifting direction Z. A guide cylinder 210 is sleeved on the outside of the guide post 231. The lifting base 230 provides stability for the lifting device 20. One end of the guide post 231 is fixedly connected to the lifting base 230. The guide post 231 stands upright on the lifting base 230 along the lifting direction Z, and the inner wall of the guide cylinder 210 slides against the outer wall of the guide post 231 to allow the guide cylinder 210 to move in the lifting direction Z. The lifting base 230 may be I-shaped to provide better stability for the lifting device 20. The guide post 231 can be a hollow post so that the threaded post 220 can be inserted into the guide cylinder 210 and also located inside the guide post 231. This allows the threaded post 220 to be longer, thereby increasing the adjustable stroke range of the threaded post 220.

[0039] In some embodiments, the lifting device 20 includes a pressing assembly 240, which includes a pressing body 241 and a rotating hole 2411. A supporting column 232 is provided at one end of the lifting base 230 away from the guide column 231. The pressing body 241 has a rotating portion 2412 rotatably connected to the end of the supporting column 232 away from the lifting base 230. A rotating pin 2111 is provided on the side of the guide cylinder 210 near the pressing assembly 240 in the lateral direction X, and the rotating pin 2111 is inserted into the rotating hole 2411. The lifting base 230 has the supporting column 232, and the middle part of the pressing body 241 has the rotating portion 2412 rotatably connected to the supporting column 232. A rotating pin 2111 is positioned laterally (X) on one side of the guide cylinder 210 near the pressing body 241. The pressing body 241 has a rotating hole 2411 at one end near the guide cylinder 210, which connects to the rotating pin 2111. Both ends of the rotating pin 2111 pass through the rotating hole 2411. The dimension of the rotating hole 2411 in the direction from the guide cylinder 210 to the support column 232 is larger than the radial dimension of the rotating pin 2111. This allows the pressing body 241 to press against the supporting column 232 when rotating, causing the rotating hole 2411 to abut against the rotating pin 2111, thereby providing a driving force for the guide cylinder 210 to move in the lifting direction (Z). The larger size of the rotating hole 2411 than the rotating pin 2111 allows for changes in the relative position of the rotating pin 2111 within the rotating hole 2411, thus allowing the guide cylinder 210 to move in the lifting direction (Z). Specifically, the rotating part 2412 can also be two through holes arranged opposite each other, and the support column 232 is provided with a pin in the transverse direction X. The pin is inserted into the two through holes so that the rotating part 2412 can rotate.

The limiting piece 2321 is spaced apart from the pressing main body 241, and the limiting piece 2321 is rotationally connected with the support column 232 to allow the limiting piece 2321 to rotate. The fixing pin 2413 is arranged on the side of the pressing main body 241 corresponding to the limiting piece 2321, and the fixing pin 2413 is spaced apart from the limiting piece 2321. The end of the limiting piece 2321 away from the support column 232 is provided with a bayonet, and the radial dimension of the bayonet is matched with the radial dimension of the fixing pin 2413, so that the bayonet is connected or separated with the fixing pin 2413 by rotating the limiting piece 2321. When the pressing main body 241 is pressed to make the guide cylinder 210 rise along the lifting direction Z, the limiting piece 2321 and the fixing pin 2413 can be connected, so that the guide cylinder 210 can be maintained in the lifted state, thereby freeing the worker's hands to provide downward pressure on the pressing main body 241, and facilitating the installation of the workpiece 2 to be installed. The end of the pressing main body 241 away from the guide cylinder 210 can also be provided with a booster rod to extend the pressing main body 241, so that more effort can be saved when pressing the pressing main body 241.

The moving base 30 comprises the support 320, which can provide the moving base 30 with a mounting framework, so that the weight of the support 320 is small and space required for mounting other components can be provided. The end of the support 320 close to the lifting device 20 is provided with the limiting groove 310, the lifting base 230 can be mounted in the limiting groove 310, and the circumferential side of the lifting base 230 can abut against the side wall of the limiting groove 310, so that the lifting base 230 can be limited in the limiting groove 310, thereby avoiding shaking of the lifting base 230.

[0044] In some embodiments, the profiling fixing assembly 100 comprises a profiling piece 110 and a fastener 120, the fastener 120 cooperates with the profiling piece 110 to surround the outside of the workpiece 2 to be installed, the profiling piece 110 and the fastener 120 are fixedly attached to the outside of the workpiece 2 to be installed on the side close to the workpiece 2 to be installed, one end of the fastener 120 is rotationally connected to one end of the profiling piece 110, and the other end of the fastener 120 is detachably connected to the other end of the profiling piece 110. The fastener 120 cooperates with the profiling piece 110 to form a structure similar to a ring, so that one end of the workpiece 2 to be installed can be fixed in the ring structure formed by the profiling piece 110 and the fastener 120. The inner walls of the profiling piece 110 and the fastener 120 can be attached to the outer wall of the workpiece 2 to be installed, thereby increasing the contact area between the profiling fixing assembly 100 and the workpiece 2 to be installed, so that the workpiece 2 to be installed can be fixed more firmly, and the risk of scratching the workpiece 2 to be installed can be reduced. One end of the fastener 120 can be rotationally connected to one end of the profiling piece 110, the other end of the fastener 120 can be provided with a locking buckle, and the other end of the profiling piece 110 is provided with a pin buckle detachably connected to the locking buckle.

The profiling fixing assembly 100 is fixed to the inclined base 130, the inclined bottom surface 131 is located on the side of the inclined base 130 connected with the profiling fixing assembly 100, and the inclined bottom surface 131 receives the workpiece 2 to be installed, so that the workpiece 2 to be installed is also inclined towards one side of the profiling piece 110, thereby making the workpiece 2 to be installed have a suitable installation posture when being fixedly connected with the vehicle body, and facilitating the positioning and fixing of the workpiece 2 to be installed with the vehicle body. In addition, the fastener 120 and the profiling piece 110 are oppositely arranged, the fastener 120 is opposite to the inclined direction of the workpiece 2 to be installed, thereby reducing the pressure on the locking buckle and reducing the possibility of deformation of the locking buckle and the pin buckle.

One end of the buffer 250 can be fixed to the side of the lifting base 230 away from the moving part 330. The other end of the buffer 250 is connected with the outside of the guide cylinder 210, and the buffer 250 can provide a force for the guide cylinder 210 to move in the lifting direction Z. The position corresponding to the connection between the guide cylinder 210 and the buffer 250 is provided with an extension, which extends in the horizontal direction towards the buffer 250, thereby providing space for the installation of the buffer.
