In the technical requirements for the connection box 4, a certain positional accuracy and dimensional accuracy must be ensured between the mounting holes for installing the slider guide rod on the flanges on both sides of the connection box 4 and the two mounting holes for assembling the crank; in addition, a certain coaxial accuracy must be ensured between the mounting hole for installing the crank on the upper end cover of the box and the mounting hole for installing the crank in the connection box 4, so as to ensure that the crank, guide slider and other parts installed in the connection box 4 can operate normally.

[0019] The detection device comprises a detection platform 1, the surface of which is provided with crisscrossed T-shaped grooves 1-1, in which slidable T-shaped blocks 12 are embedded, and a positioning cavity 1-2 is provided at the center of the detection platform 1.

[0020] The detection platform 1 is provided with a positioning platform 2 at the center, and a positioning boss 2-1 is provided on the bottom surface of the positioning platform 2. The positioning boss 2-1 cooperates with the positioning cavity 1-2 to realize the positioning and installation of the positioning platform 2 on the detection platform 1. A detection cover plate 3 is provided above the positioning platform 2, and the connection box 4 to be detected is positioned between the positioning platform 2 and the detection cover plate 3. The detection cover plate 3 is fixed to the upper end surface of the connection box 4 by four cylindrical pins. A coaxiality detection shaft 5 is passed from the detection cover plate 3 to the positioning platform 2. The coaxiality detection shaft 5 passes through the positioning hole on the detection cover plate 3, and the shaft end at the lower end thereof is inserted into the center hole of the positioning platform 2.

[0021] Two core shaft supports 6 are arranged on the detection platform 1 on the left side of the connecting box 4, and the lower end of the core shaft support 6 is fixedly connected to the T-block 12. To facilitate the positioning and anti-rotation of the core shaft support 6, limit blocks 13 are respectively provided in the T-slots 1-1 on both sides of the T-block 12, and the limit blocks 13 are fixed to the lower end of the core shaft support 6.

[0022] A detection spindle 7 is provided between the two spindle supports 6 , and the detection spindle 7 is vertical to the coaxiality detection axis 5 in space. A detection support 8 is fixed to the bottom surface of the detection cover plate 3 , and the detection spindle 7 and the center hole of the detection support 8 are clearance-matched.

[0023] A rotating shaft 9 is installed on the detection platform 1 on the right side of the connecting box 4, and an adjustment plate 14 is connected below the rotating shaft 9, and both sides of the adjustment plate 14 are fixedly connected to T-blocks 12 respectively; a rotating adjustment block 10 is rotatably provided on the upper end of the rotating shaft 9, and both ends of the rotating adjustment block 10 are respectively connected to adjustment screws 11 that rest against the side wall of the connecting box 4 during measurement.

[0024] When installing the detection device, first install the positioning platform 2 on the detection platform 1 with the help of the cooperation between the positioning boss 2-1 and the positioning cavity 1-2, and then position the connecting box 4 on the boss on the upper end face of the positioning platform 2; install the detection support 8 on the bottom surface of the detection cover 3, position it through two cylindrical pins and fix the detection support 8 to the bottom surface of the detection cover 3 with hexagon socket screws, and finally, position the detection cover 3 on the upper end face of the connecting box 4 through four cylindrical pins.

[0025] Check the coaxiality: insert the coaxiality detection shaft 5 downward through the center hole on the detection cover 3 so that the slender end of the lower end of the coaxiality detection shaft 5 can be inserted into the center hole of the positioning table 2. In this way, it can be detected whether the coaxiality accuracy between the crank mounting hole in the connecting box 4 and the crank mounting hole on the upper end cover of the box meets the assembly technical requirements.

[0026] Check the position and dimensional accuracy between the slider guide rod mounting hole and the crank mounting hole:

[0027] Install the detection mandrel 7, insert the detection mandrel 7 through the center hole of the mandrel support 6 on the right side of the connecting box 4, use two adjusting screws 11 to push the connecting box 4 to rotate, so that the detection mandrel 7 passes through the mounting hole of the slider guide rod on the flange on one side of the connecting box 4, and lock the adjusting screw 11 by rotating the locking nut on the back of the adjusting block 10, and pass the detection mandrel 7 through the center hole of the detection support 8, and then pass it out from the mounting hole of the slider guide rod on the flange on the other side of the connecting box 4, and finally pass it out from the center hole of the mandrel support 6 on the left side of the connecting box 4. After such installation, the distance between the axis of the detection mandrel 7 and the axis of the coaxiality detection shaft 5 is the distance between the mounting hole for the slider guide rod on the flange and the two mounting holes for assembling the crank; and the height between the center of the center hole of the detection support 8 and the bottom surface of the connecting box 4 is the height of the mounting hole for the slider guide rod on the flange.

[0028] In this way, the installation of the detection spindle 7 can be used to detect whether the position and dimensional accuracy between the mounting holes for mounting the slider guide rod on the flanges on both sides of the connecting box 4 and the two mounting holes for assembling the crank meet the technical requirements.

[0029] In the above-mentioned installation process, if after the adjusting screw 11 is locked, the detection spindle 7 can pass through the center hole of the subsequent detection support 8 and the mounting hole for installing the slider guide rod on the flange on the other side of the connecting box 4, it means that the positional accuracy and dimensional accuracy between the mounting holes for installing the slider guide rod on the flanges on both sides of the connecting box 4 and the two mounting holes for assembling the crank meet the technical requirements; on the contrary, if the detection spindle 7 cannot pass through the center hole of the subsequent detection support 8 or the mounting hole for installing the slider guide rod on the flange on the other side of the connecting box 4, it means that the positional accuracy and dimensional accuracy between the mounting holes for installing the slider guide rod on the flanges on both sides of the connecting box 4 and the two mounting holes for assembling the crank do not meet the technical requirements.
