When the vertical line from the midpoint of the casting table 101 to the welded steel pillow bars 106 is taken as the middle bisector of the casting table 101, the axis center hole 105 and the two positioning columns 110 are located on the same side of the middle bisector;

[0040] The rotating shaft column 107 is fixedly connected to the shaft center hole 105 , and the two positioning columns 110 are respectively threadedly connected to the two column threaded holes 104 .

[0041] Please pay attention to Figure 2 , Figure 5 The bearing sleeve 201 is provided with an inner diameter bayonet 202 having upper and lower bottom surfaces penetrating therethrough on one side thereof close to the column threaded hole 104, and a line connecting the midpoint of the cross section of the inner bottom surface of the inner diameter bayonet 202 to the axis position of the bearing sleeve 201 and the middle bisector of the casting table 101 are located in a unified vertical plane;

[0042] An external connection port 203 is provided at the upper edge of the outer wall of the bearing sleeve 201 , and a line connecting the midpoint of the outer circular edge of the external connection port 203 and the midpoint of the bearing sleeve 201 and the midline of the steel plate base 205 are located in the same vertical plane.

[0045] Please pay attention to Figure 3 , Figure 6 The casting table 101 is provided with a movable guide rail 102 on the circumferential side surface. The movable guide rail 102 is an annular guide rail. A movable extrusion table 103 is slidably connected inside the annular guide rail. The movable extrusion table 103 includes a base connected to the movable guide rail 102, an arc-shaped support plate, and a blocking force block 112. A blocking force block 112 is provided on one side of the arc-shaped support plate in an area higher than the height of the casting table 101. The side surface of the blocking force block 112 is connected to the inner surface of the movable extrusion table 103, and the bottom surface of the blocking force block 112 is in contact with the upper surface of the casting table 101.

[0049] The bearing sleeve 201 is used to cooperate with the rotating shaft column 107. The bearing sleeve 201 and the entire bearing base 2 are directly positioned by the inner diameter bayonet 202 and the positioning block 109 that penetrate and slide relatively from top to bottom. When the position is put in, the steel plate base 205 can be matched for comparison. If there is an obvious deviation after the steel plate base 205 contacts the positioning column 110, it is installed incorrectly, and the steel plate base 205 needs to be turned over for comparison again, which plays a self-checking role.

[0050] The peripheral positioning bayonet 108 of the rotating shaft column 107 is used to display different heights. The height of the steel plate base 205 needs to be reserved on the peripheral side of the bottom of the rotating shaft column 107, but the height of the vertical welding plate 204 needs to be calibrated on the upper part. Therefore, the positioning bayonet 108 can be used to know whether the vertical welding plate 204 is located on the correct side of the steel plate base 205;

[0051] The sinking setting of the external connection port 203 is the same as described above, and the vertical welding plate 204 can be identified, and the opening angle chord length of the external connection port 203 is equal to the thickness of the vertical welding plate 204, which can greatly avoid the vertical welding plate 204 from artificial welding deviation;

[0052] The direction of the line connecting the midpoints of the two positioning columns 110 is the same as the direction of the oblique line of any side of the steel plate base 205. The front and back sides of the steel plate base 205 can be compared, and the side pass of the steel plate base 205 can be checked. At the same time, when the length of the oblique side is long, it can still be adapted for use with the bearing base 2.

[0053] When the operator processes the bearing base 2, he first puts the accessory bearing sleeve 201 into the rotating shaft column 107, places the steel plate base 205 on the upper part of the welded steel pillow bar 106 for easy access, aligns one side of it with the sides of the two positioning columns 110, and spot welds them to fix them. At this time, take the vertical welding plate 204 and align its oblique side as shown in the figure. Figure 2 As shown, the connecting surface of the external connecting port 203 is aligned. At this time, the height is observed to be consistent, so the vertical welding plate 204 and the outer wall of the bearing sleeve 201 are spot-welded to fix them. The thickness and the positional relationship between the two ends of the external connecting port 203 are observed. The handle column 111 is used to drive the movable extrusion platform 103 to rotate until the blocking force block 112 contacts the other side of the steel plate base 205. After the steel plate base 205 is pressed, the connecting line is welded.
