The door leaf hanging frame 410 is provided with a plurality of top rods 430 with the front ends abutting against the door leaf.

[0024] The positioning and clamping assembly 140 of the door frame assembly tooling 100 is used to clamp the door frame. The size of the square mounting frame 110 matches the size of the door frame. The left vertical rod 111, the upper cross rod 112, the right vertical rod 113, and the lower cross rod 114 are assembled to form the square mounting frame 110. The limit handle 150 is used to abut against the outer side of the motor car body 600. The upper pressure rod frame 120 and the lower pressure rod frame 130 are pressed backward under the action of the upper clamp 170 and the lower clamp 180. Both the upper pressure rod frame 120 and the lower pressure rod frame 130 are used to press backward from the inner side of the motor car body 600. Then, in cooperation with the limit handle 150, the square mounting frame 110 can be clamped at the doorway of the motor car body 600. Moreover, the positioning and clamping assembly 140 clamps the door frame to be installed. Then, the door frame assembly tooling 100 can firmly assemble the door frame to the doorway of the motor car body 600 to complete the positioning. The pin 161 is used to limit the movement directions of the upper pressure rod frame 120 and the lower pressure rod frame 130, achieving the effect of initially positioning the upper pressure rod frame 120 and the lower pressure rod frame 130. In cooperation with the upper clamp 170 and the lower clamp 180, the upper pressure rod frame 120 and the lower pressure rod frame 130 can be stably pressed on the inner side surface of the motor car body 600, making the clamping of the upper pressure rod frame 120 and the lower pressure rod frame 130 more stable. When in use, first clamp the door frame on the positioning and clamping assembly 140 for fixation, lift the door frame assembly tooling 100 by a crane, slowly approach the doorway of the motor car body 600, finally support the outer side of the motor car body 600 with the limit handle 150, and press the inner side of the motor car body 600 with the upper pressure rod frame 120 and the lower pressure rod frame 130 to achieve the purpose of clamping the door frame assembly tooling 100 at the doorway of the motor car body 600. Subsequently, the gap between the door frame and the doorway of the motor car body 600 can be directly glued to complete the installation of the door frame. Then, the positioning and handling of the door frame are completed without manual handling and positioning, reducing the labor intensity of workers, reducing the steps of manual measurement and positioning, greatly reducing the installation difficulty of the door frame, reducing the installation technical requirements for installation workers, making it easier for different installation workers to install the door frame, improving the installation quality of the door frame, and ensuring the normal use of the EMU door. The side-standing integrated component tooling 200 is used for the side-standing integrated component. When in use, first install the side-standing integrated component on the side-standing integrated component tooling 200, and then lift the side-force integrated component tooling by a crane and install it on the right vertical rod 113 to complete the positioning of the side-force integrated component tooling. Then, the installation of the side-standing integrated component is completed by finally installing the side-standing integrated component on the doorway of the motor car body 600. Then, the positioning and handling of the side-standing integrated component are completed without manual handling and positioning, reducing the labor intensity of workers, reducing the steps of manual measurement and positioning, greatly reducing the installation difficulty of the side-standing integrated component, reducing the installation technical requirements for installation workers, making it easier for different installation workers to install the side-standing integrated component, improving the installation quality of the side-standing integrated component, and ensuring the normal use of the EMU door.

[0025] The gripper frame 310 of the mechanism positioning tooling 300 is used to hold the door switch mechanism. The gripper frame 310 is provided with a holding groove so that the door switch mechanism can be stably placed on the gripper frame 310 and is not likely to fall off. At the left and right ends of the gripper frame 310, there are quick clamps, which are common quick clamps on the market and are prior art, so they will not be elaborated here. Similarly, the upper clamp 170, the lower clamp 180, and the first clamp 149 and the second clamp 230 that appear below are all common quick clamps on the market and play the role of quick clamping. Then the gripper frame 310 can well stabilize the door switch mechanism. The universal adjustment seat 360 is a common universal seat on the market and can adjust the horizontal position of the direction of the gripper frame 310. The left and right moving device 320 has a left and right sliding plate for carrying the universal seat and a cylinder for driving the left and right sliding plate to move left and right. The front and back moving device 330 has a front and back sliding plate for carrying the cylinder of the left and right moving device 320 and a cylinder for driving the front and back sliding plate to move back and forth. The rotating device 340 has a rotating plate for carrying the cylinder of the front and back moving device 330 and a servo motor for driving the rotating plate to rotate.

Then the gripper frame 310 can move back and forth, left and right, up and down, and can also perform its own rotation action and universal adjustment rotation around the universal adjustment seat 360, which is convenient for adjusting the position between the door switch mechanism and the door frame of the EMU, so as to facilitate the positioning of the door switch mechanism. When in use, first remove the door frame assembly tooling 100, and then push the lifting trolley 350 to the inside of the EMU body 600. The gripper frame 310 is conveyed to the rear position of the door frame under the cooperation of the left and right moving device 320, the front and back moving device 330, the rotating device 340, the lifting trolley 350, and the universal adjustment seat 360 to complete the positioning, so that the door switch mechanism can be directly positioned and installed on the EMU body 600. Then, the positioning and handling of the door switch mechanism are completed without manual handling and positioning, reducing the labor intensity of workers, reducing the steps of manual measurement and positioning, greatly reducing the installation difficulty of the door switch mechanism, reducing the installation technical requirements of installation workers, making it easier for different installation workers to install the door switch mechanism, improving the installation quality of the door switch mechanism, and ensuring the normal use of the EMU door.

[0026] On both sides of the door leaf hanger 410 of the door leaf tooling 400, there are two suspension rods 411 respectively. The suspension rod 411 has a U-shaped buckle 412 for buckling the left and right sides of the door leaf. The length of the U-shaped buckle 412 is greater than the thickness of the sealing strip of the door leaf edge wrapping, so as to prevent the U-shaped buckle 412 from damaging the sealing strip of the door leaf. The support block 420 is used to support the bottom edge of the door leaf, and the ejector rod 430 is threadedly connected to the door leaf hanger 410. When in use, the door leaf is buckled on the U-shaped buckle 412, the bottom of the door leaf is supported on the support block 420, and the ejector rod 430 is rotated so that the end of the ejector rod 430 abuts against the door leaf, preventing the door leaf from shaking, falling off or being scratched during movement. Then, the door leaf tooling 400 is moved to the door of the EMU car body 600 by a crane, and the installation of the door leaf begins. Thus, the positioning and handling of the door leaf are completed without manual handling and positioning, reducing the labor intensity of workers, reducing the steps of manual measurement and positioning, greatly reducing the installation difficulty of the door leaf, lowering the installation technical requirements for installers, making it easier for different installers to install the door leaf, improving the installation quality of the door leaf, and ensuring the normal use of the EMU door.

[0027] Refer to Figures 1 to 5, in some embodiments of the present invention, the positioning and clamping assembly 140 includes a plurality of positioning blocks 141 provided on the front sides of the left vertical rod 111 and the right vertical rod 113 for supporting the door frame, a plurality of lower support seats 142 provided on the lower cross bar 114 for supporting the door frame, and a plurality of upper support seats 143 provided on the upper cross bar 112 for supporting the door frame. The lower support seat 142 is provided with a positioning rod 144 penetrating into the door frame opening. Each of the two upper forearms 160 is provided with a first clamping arm 145. The first clamping arm 145 is threadedly connected with a first handle screw rod 146. The upper end of the first handle screw rod 146 is provided with a first pressing head 147 for abutting against the upper side of the door frame. The lower cross bar 114 is provided with a second clamping arm 148. The second clamping arm 148 is provided with a first clamp 149 for pressing the door frame onto the lower support seat 142. The positioning block 141 is used to cooperate with the protruding edge of the door frame for preliminary positioning. Moreover, in cooperation with the upper support seat 143 and the lower support seat 142, the door frame assembly tool 100 can better support the door frame when placed flat, facilitating the position adjustment and clamping of the door frame. The inner side of the lower part of the door frame abuts against the positioning rod 144, and the upper part of the door frame abuts against the pressing head of the first handle screw rod 146, so that the door frame can be fixed from the upper and lower sides of the door frame. That is, when the inner side of the lower part of the door frame abuts against the positioning rod 144, the first handle screw rod 146 rotates to move the first pressing head 147 upward, pressing the inner side of the upper part of the door frame upward by the first pressing head 147, achieving the purpose of internally supporting and fixing the upper and lower sides of the door frame. Finally, the door frame is pressed onto the lower support seat 142 by the first clamp 149 to complete the clamping and fixing of the door frame, facilitating the fixing of the door frame. Among them, there are two lower forearms 160, and correspondingly, there are two lower support seats 142 and two first clamps 149. Before clamping, positioning and installing the door frame, the contour of the door frame can also be detected by using the positioning and clamping assembly 140. The detection process is as follows: place the rear side of the square installation frame 110 horizontally on the ground, then place the door frame on the upper support seat 143, the positioning block 144, and the lower support seat 142 for natural support and close fitting. Subsequently, one of the first clamps 149 presses the door frame onto the lower support seat 142, and the first clamp 149 and the lower support seat 142 clamp the door frame. At this time, the distance between the door frame and the two lower support seats 142 can be detected. If the distance between the sealing surface of the door frame and the two lower support seats 142 is not greater than 1.5 millimeters, the contour of the door frame is qualified, and the door frame can be assembled.

[0028] In some embodiments of the present invention, referring to Figure 3, it further includes a second handle screw 500 corresponding to the positioning block 141 one by one. The front end of the second handle screw 500 is rotatably connected to a first clamping block 510 for pressing the door frame against the positioning block 141. The front end of the second handle screw 500 is provided with a first limit head 520 for abutting against the first clamping block 510. The threaded section of the second handle screw 500 is threadedly connected to the left vertical rod 111 or the right vertical rod 113. The first limit head 520 is used to prevent the first clamping block 510 from disengaging from the second handle screw 500 and avoid the first clamping block 510 from falling off. The first clamping block 510 is located inside the door frame, and the positioning block 141 is used to abut against the outside of the door frame. By rotating the second handle screw 500, the distance between the first clamping block 510 and the positioning block 141 can be adjusted. Then, by rotating the second handle screw 500, the first clamping block 510 can be made to cooperate with the positioning block 141 to clamp and fix the door frame, achieving the purpose of fixing the door frame.

[0029] In some embodiments of the present invention, referring to Figures 3 to 7 , at least two positioning seats 1131 are provided on the inner side of the right vertical rod 113. The positioning seats 1131 are provided with positioning pins 1132. The side-standing integrated component tooling 200 is provided with a positioning plate 220 that abuts against the positioning seats 1131. The positioning plate 220 is provided with a positioning notch 221 for the positioning pins 1132 to insert.
