[0032] The present invention is further described in detail below with reference to specific embodiments.

[0033] Example:

[0034] like Figure 1 and Figure 2 As shown, an instrument panel tool 1 includes a base frame 11, a rotating frame 12 rotatably arranged on the base frame 11 along a first horizontal axis, and a rotation driving mechanism 13 driving the rotating frame 12 to rotate. The instrument panel 2 includes a frame portion 21 and circular tube portions 22 arranged at both ends of the frame portion 21, and the frame portion 21 is provided with a positioning hole 211 near the short side.

[0035] The instrument panel 2 in the figure is a schematic structure, which is only used to illustrate the fixing principle of the instrument panel fixture 1. The surface structures of different instrument panels 2 are designed according to the structure of the instrument panel, but the width of the skeleton part 21, the position of the positioning hole 211 and the structure of the circular tube part 22 are basically the same, so the same set of instrument panel fixture 1 can be used with various instrument panels 2. The rotation drive mechanism 13 is used to enable the instrument panel to rotate along the same first horizontal axis to meet the working needs.

[0036] like Figure 2As shown, the base frame 11 includes a base 111, a first articulated frame 112a arranged on one side of the base 111 and a second articulated frame 112b arranged on the other side of the base 111, the rotation drive mechanism 13 is arranged on one side of the first articulated frame 112a, the rotating frame 12 includes a first positioning mechanism 121a rotatably connected to the first articulated frame 112a, a second positioning mechanism 121b rotatably connected to the second articulated frame 112b and a pull rod 122 connecting the first positioning mechanism 121a and the second positioning mechanism 121b together, and the first positioning mechanism 121a and the second positioning mechanism 121b are symmetrical in structure and rotate about the same axis.

[0037] The first positioning mechanism 121a and the second positioning mechanism 121b are the fixing bases of the instrument panel 2. The pull rod 122 is used to maintain the relative position between the first positioning mechanism 121a and the second positioning mechanism 121b, and also to provide a rotation force application position for the operator.

[0038] like Figure 3 As shown, the first positioning mechanism 121a and the second positioning mechanism 121b both include a base plate 1211 , a first clamping platform 1212a , a second clamping platform 1212b , a driving shaft 1213 , a first locking block 1214 , a second locking block 1215 , a locking sleeve 1216 and a spring 1217 .

[0039] like Figures 3 to 6 As shown, the first clamping platform 1212a and the second clamping platform 1212b are arranged side by side on the base plate 1211 along the second horizontal axis, and a positioning pin 12121 matching the positioning hole 211 is fixed on the upper surface of the first clamping platform 1212a or the second clamping platform 1212b, and a first folding plate 12122 is provided on the first clamping platform 1212a, and a second folding plate 12123 is provided on the second clamping platform 1212b, and the first folding plate 12122 and the second folding plate 12123 form an open structure of the outer end of the limiting circular tube portion 22.

[0040] When the base plate 1211 is in a horizontal position, the instrument panel 2 is placed from top to bottom on the first clamping platform 1212a and the second clamping platform 1212b. On the one hand, the positioning hole 211 on the skeleton part 21 is penetrated by the positioning pin 12121, and on the other hand, the end of the circular tube part 22 is simultaneously close to the inner side of the first folding plate 12122 and the second folding plate 12123, thereby realizing the initial positioning of the instrument panel 2.

[0041] like Figures 3 to 7As shown, the driving shaft 1213 passes through the first clamping platform 1212a and the lower part of the second clamping platform 1212b along the second horizontal axis, the second horizontal axis is perpendicular to the first horizontal axis, the first locking block 1214 is movably set on the first clamping platform 1212a along the first horizontal axis and a first rack 12141 is provided at the lower part, the second locking block 1215 is movably set on the second clamping platform 1212b along the first horizontal axis and a second rack 12151 is provided at the lower part, a T-shaped turning handle 12131 is provided on each side of the driving shaft 1213, and a first transmission gear 12132, a second transmission gear 12133 and a stop pin 12134 are also provided on the driving shaft 1213 in sequence, the first transmission gear 12132 is located inside the first clamping platform 1212a and is meshed with the first rack 12141, the second transmission gear 12133 is located inside the second clamping platform 1212b and is meshed with the second rack 12151.

[0042] Through the gear rack structure, the driving shaft 1213 can simultaneously drive the first locking block 1214 and the second locking block 1215 to move along the first horizontal axis, so that the ends of the first locking block 1214 and the second locking block 1215 respectively abut against the wide side of the frame part 21. The T-shaped handle 12131 can facilitate workers to complete the two actions of pushing, pulling and rotating with one hand.

[0043] like Figures 4 to 9 As shown, the locking sleeve 1216 is fixed to one side of the second clamping platform 1212b, and the locking sleeve 1216 is provided with an L-shaped hole 12161 for limiting the moving track of the anti-rotation pin 12134. The L-shaped hole 12161 includes a straight section 121611 extending along the generatrix and an arc section 121612 extending along the circumferential direction. The arc section 121612 is provided with a clamping groove 121613 at one end away from the straight section 121611 to hinder the movement of the anti-rotation pin 1234. The spring 1217 is passed through by the driving shaft 1213 and the two ends are respectively abutted on the locking sleeve 1216 and a T-shaped rotating handle 12131 thereof. The second locking block 1215 is rotatably connected to the second rack 12151 and has locking tongues of different heights at both ends. The second clamping platform 1212b is provided with a long hole 12124 for guiding the second rack 12151 to advance and retreat along the first horizontal axis and a circular groove 12125 for the second locking block 1215 to rotate around the vertical axis. When the stop pin 1234 is located in the clamping groove 121613, the rotation axis of the second locking block 1215 is colinear with the center of the circular groove 12124. The second clamping platform 1212b is also provided with a guide groove block 1218 that crosses the long hole 12124. The spacing between the groove walls on both sides of the guide groove block 1218 is equal to the width of the second locking block 1215, and the groove wall is open on the side close to the circular groove 12125.

[0044] The second locking block 1215 will be in a Z-shaped structure, with locking tongues at both ends, which can be interchanged, so as to adapt to two types of instrument panels 2, and the drive shaft 1213 can not only rotate but also move axially. The spring 1217 will apply an axial force to the T-shaped handle 12131, and the stop pin 12134 can stop at two positions: the end of the straight section 121611 and the clamping groove 121613. When the stop pin 12134 is located in the clamping groove 121613, the second rack 12151 is pulled outward, so that the second locking block 1215 can rotate within the range limited by the circular groove 12125, so that the lock tongue of the second locking block 1215 can be changed; when the stop pin 12134 is rotated into the straight section 121611, one of the lock tongues will be inserted into the guide groove block 1218, and the two walls of the guide groove block 1218 have a guiding function, so that the extension direction of the lock tongue is accurate.

[0045] The workflow of instrument panel tooling 1 is:

[0046] During assembly, the two ends of the instrument panel 2 are placed on the first positioning mechanism 121a and the second positioning 121b respectively by using the positioning hole 211 and the positioning pin 12121. The first folding plate 12122 and the second folding plate 12123 will complete the initial positioning by limiting the outer end of the circular tube part 22 during the positioning of the frame part 21. During this process, the operator needs to hold one end of the frame part 21 with one hand, and operate the T-shaped handle 12131 with the other hand, so that the first locking block 1214 and the second locking block 1215 are in the outward retreat position; after the instrument panel 2 is in place, the operator rotates the T-shaped handle 12131, and the two gears simultaneously drive the first locking block 1214 and the second locking block 1215 to approach the wide side of the frame part 21 and completely clamp it on the rotating frame 12. Therefore, at this time, the rotating frame 12 can be rotated by relying on the rotating drive mechanism 13 to adjust the rotation angle of the instrument panel, thereby meeting the processing positioning needs.

[0047] When changing the model, one hand is required to push the T-shaped handle near one end of the locking sleeve 1216 or pull the T-shaped handle at the other end, and then rotate it until the stop pin 12134 enters the snap-in groove 121613, and the other hand rotates the second locking block 1215 180°, and then the first hand rotates the T-shaped handle 12131 to reset the first locking block 1214 and the second locking block 1215.

[0048] The above device can use the cooperation of both hands to quickly fix the instrument panel online, speed up the clamping efficiency, and adapt to the processing rhythm of the instrument panel.

[0049] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
