[0007] According to the above technical solution, the adaptation device also includes four telescopic hinged rods, four ''-shaped splints, four fixed shafts, four L-shaped track plates, and two connecting plates. The two connecting plates are respectively fixed on the side where the L-shaped moving blocks are close to each other. The four L-shaped track plates are respectively fixed at the four corners of the bottom of the placement table. The four ''-shaped splints are respectively slidably installed on the side of the four L-shaped track plates away from the center of the placement table. One end of the four telescopic hinged rods is respectively hinged on both sides of the two connecting plates, and the other ends of the four telescopic hinged rods are respectively hinged on the outer walls of the four ''-shaped splints. The bottom of the telescopic hinge rod is provided with a sliding groove on one side near the connecting plate, and the sliding grooves of the four telescopic hinge rods are respectively slidably installed on the fixed shaft, and the fixed shaft is fixed to the bottom of the placement table. At the same time, when the L-shaped moving block moves in the direction away from the center of the placement table, it will drive the connecting plate to move along, and the connecting plate will drive one end of the telescopic hinge rod to move along, and the other end of the telescopic hinge rod will rotate around the fixed shaft, so that the other end of the telescopic hinge rod drives the several-shaped splint to move along the L-shaped track plate toward the center of the placement table, and the several-shaped splint will clamp and fix the lugs of the supporting wheel side cover.

[0011] The present invention provides an improved turning table for processing the side cover of a supporting wheel, which has the following beneficial effects:

[0012] (1) The present invention adopts the setting of the adaptation device, so that the bidirectional screw rod, the L-shaped moving block, and the placement table cooperate to drive the push column to push the inner wall of the supporting roller side cover to drive the supporting roller side cover to be centered on the placement table, and the push column will fix the supporting roller side cover on the placement table, so that the turning table can adapt to the turning processing of supporting roller side covers of various models and sizes; at the same time, the L-shaped moving block, the placement table, the connecting plate, the telescopic hinge rod, the fixed shaft, and the L-shaped track plate cooperate to drive the L-shaped clamping plate to clamp and fix the lug of the supporting roller side cover, thereby improving the stability of the supporting roller side cover on the placement table, which is beneficial to the subsequent processing of the lug of the supporting roller side cover; The L-shaped moving block and the push column cooperate to drive the L-shaped rod to apply pressure to the top of the supporting wheel side cover. The pressure applied by the L-shaped rod can ensure that the supporting wheel side cover is firmly fixed and aligned on the placing table. This fixation can prevent the supporting wheel side cover from shifting in the processing position due to movement or shaking during the flipping process. As the push column drives the L-shaped rod to continue to move, the push column drives the push plate to contact the inner wall of the supporting wheel side cover. The inner wall of the supporting wheel side cover pushes the push plate toward the push column, and the push plate drives the positioning rod to drive the serrated groove of the serrated plate to engage with the serrated groove of the L-shaped rod, so that the serrated plate fixes the position of the L-shaped rod, thereby improving the stability of the pressure applied by the L-shaped rod to the top of the supporting wheel side cover.

[0013] (2) The present invention provides a stabilizing device so that the push column, the fixing plate, the air pipe, the suction cup, the U-shaped column, and the elastic folding bag cooperate to generate negative pressure at the suction cup, so that the suction cup is adsorbed and fixed to the inner wall of the supporting wheel side cover. The adsorption effect of the suction cup can effectively fix the supporting wheel side cover on the placement table to ensure that it will not move or shake during the processing. This stability is particularly important for precision processing operations and can ensure the accuracy and consistency of processing.

[0014] (3) The present invention sets a limiting device so that the placement table, motor, rotating rod, connecting rod, semi-arc rod, and triangular telescopic rod cooperate to drive the triangular telescopic end of the triangular telescopic rod to extend into the triangular groove of the semi-arc rod, so that the triangular telescopic rod limits the flipping position of the placement table through the semi-arc rod, thereby accurately limiting the flipping angle of the placement table, thereby ensuring that the placement table drives the supporting wheel side cover to achieve the precise position requirement each time it flips. Compared with the existing self-locking motor, the method of using the triangular telescopic rod and the semi-arc rod to cooperate in limiting the position is lower in cost than the self-locking motor. The self-locking motor usually requires a complex electronic control system and sensors to ensure the precise control and safety of the angle. These additional electronic components and equipment increase the cost. BRIEF DESCRIPTION OF THE DRAWINGS

The four L-shaped track plates 57 are respectively fixed at the four corners of the bottom of the placement table 4. The four shaped clamping plates 55 are respectively slidably installed on the sides of the four L-shaped track plates 57 away from the center of the placement table 4. One end of the four telescopic hinged rods 54 is respectively hinged to the two sides of the two connecting plates 513. The four telescopic hinged rods 54 are respectively hinged to the two sides of the two connecting plates 513. The other ends of the rods 54 are hinged to the outer walls of four "X"-shaped splints 55, and the bottoms of the four telescopic hinged rods 54 close to the connecting plate 513 are provided with sliding grooves, and the sliding grooves of the four telescopic hinged rods 54 are slidably installed on the fixed shafts 56, and the fixed shafts 56 are fixed to the bottom of the placement table 4. Through the arrangement of the above structure, the "X"-shaped splints 55 can clamp and fix the lugs of the supporting wheel side covers, thereby improving the stability of the supporting wheel side covers on the placement table 4, which is beneficial to the subsequent processing of the lugs of the supporting wheel side covers.

[0027] The adaptation device 5 also includes two L-shaped rods 58, two push plates 59, two partitions 510, two serrated plates 511, and two positioning rods 512. The two L-shaped rods 58 are respectively passed through and slidably installed on the top of the push column 53, and a spring is provided between the L-shaped rod 58 and the push column 53. A groove is provided on the side of the two push columns 53 away from each other. The two partitions 510 are respectively fixed in the grooves of the two push columns 53.

The two positioning rods 512 are respectively fixed on the side of the two serrated plates 511 away from each other, and the positioning rods 512 pass through the partitions 510. The two push plates 59 are respectively fixed on the side of the two positioning rods 512 away from the serrated plates 511, and a spring is provided between the push plates 59 and the partitions 510. The L-shaped rods 58 are away from the placement table 4. A plurality of serrated grooves are provided on one side of the center of the support platform 4, a plurality of serrated grooves are provided on the side of the serrated plate 511 close to the center of the placement platform 4, and a push column 53 is protruded on the side of the push plate 59 away from the positioning rod 512. Through the arrangement of the above-mentioned structure, the L-shaped rod 58 applies pressure to the top of the supporting wheel side cover. The pressure applied by the L-shaped rod 58 can ensure that the supporting wheel side cover is firmly fixed and aligned on the placement platform 4. This fixation can prevent the supporting wheel side cover from shifting the processing position due to movement or shaking during the flipping process. At the same time, through the arrangement of the above-mentioned structure, the push plate 59 pushes the positioning rod 512 to drive the serrated groove of the serrated plate 511 to engage with the serrated groove of the L-shaped rod 58, so that the serrated plate 511 fixes the position of the L-shaped rod 58, thereby improving the stability of the pressure applied by the L-shaped rod 58 on the top of the supporting wheel side cover.

[0028] When in use, the supporting roller side cover is placed on the placing platform 4, and the bidirectional screw 51 is rotated. The bidirectional screw 51 drives the two L-shaped moving blocks 52 to move along the slide groove of the placing platform 4 in the direction away from the center of the placing platform 4, and the L-shaped moving block 52 drives the push column 53 to move accordingly. The push column 53 contacts the inner wall of the supporting roller side cover, and the push column 53 pushes the inner wall of the supporting roller side cover to drive the supporting roller side cover to be centered on the placing platform 4, and the push column 53 fixes the supporting roller side cover on the placing platform 4, so that the turning platform can adapt to the supporting roller side covers of various models and sizes. At the same time, when the L-shaped moving block 52 moves in the direction away from the center of the placement table 4, the connecting plate 513 will be driven to move along, and the connecting plate 513 will drive one end of the telescopic hinge rod 54 to move along, and the other end of the telescopic hinge rod 54 will rotate around the fixed shaft 56, so that the other end of the telescopic hinge rod 54 drives the shaped clamping plate 55 to move along the L-shaped track plate 57 toward the center of the placement table 4, and the shaped clamping plate 55 will clamp and fix the lug of the supporting wheel side cover, thereby improving the stability of the supporting wheel side cover on the placement table 4, which is beneficial to the rear The lugs of the roller side cover are processed continuously; when the L-shaped moving block 52 drives the push column 53 to move, the push column 53 drives the L-shaped rod 58 to move along with it. During this process, the L-shaped rod 58 is pulled upward, and the spring corresponding to the L-shaped rod 58 is compressed, so that the top of the L-shaped rod 58 is placed on the top edge of the roller side cover. Then, the L-shaped rod 58 is released, and under the action of the spring force corresponding to the L-shaped rod 58, the L-shaped rod 58 applies pressure to the top of the roller side cover. The pressure applied by the L-shaped rod 58 can ensure that the roller side cover is firmly fixed and aligned on the placement table 4. This fixation can prevent the processing position from being offset due to movement or shaking during the flipping process of the supporting roller side cover. As the push column 53 drives the L-shaped rod 58 to continue to move, the push column 53 drives the push plate 59 to contact the inner wall of the supporting roller side cover. The inner wall of the supporting roller side cover pushes the push plate 59 toward the push column 53. The push plate 59 pushes the positioning rod 512 to drive the serrated groove of the serrated plate 511 to engage with the serrated groove of the L-shaped rod 58, so that the serrated plate 511 fixes the position of the L-shaped rod 58, thereby improving the stability of the pressure applied by the L-shaped rod 58 on the top of the supporting roller side cover.

[0029] See also Figure 1-8 On the basis of the above embodiment, in another embodiment of the present invention, a stabilizing device 6 is provided on the side where the two push pins 53 are close to each other.

[0030] The stabilizing device 6 includes a fixing plate 61, an elastic folding bag 62, two air tubes 63, two U-shaped columns 64, and two suction cups 65. The fixing plate 61 is fixed to the side of the push column 53 close to the center of the placing table 4, the elastic folding bag 62 is fixed to the side of the fixing plate 61 away from the push column 53, the two air tubes 63 are respectively penetrated and slidably installed on both sides of the fixing plate 61, and one end of the air tube 63 is fixed to the inner wall of the side of the elastic folding bag 62 away from the fixing plate 61, the two U-shaped columns 64 are fixed to the other end of the air tube 63, and the two suction cups 65 are respectively rotatably installed on the outside of the U-shaped column 64, and the suction cups 65 are respectively rotated to the outside of the U-shaped column 64. The disc 65 is connected to the inside of the air pipe 63, and a notch is provided at one end of the air pipe 63 close to the elastic folded bag 62. Through the arrangement of the above structure, the elastic folded bag 62 draws air from the suction cup 65 through the notch of the air pipe 63, thereby generating negative pressure at the suction cup 65, so that the suction cup 65 is adsorbed and fixed to the inner wall of the supporting wheel side cover. The adsorption effect of the suction cup 65 can effectively fix the supporting wheel side cover on the placement table 4 to ensure that it will not move or shake during the processing. This stability is particularly important for precision processing operations and can ensure the accuracy and consistency of the processing.

[0031] A limiting device 7 is provided below the placement table 4. The limiting device 7 includes a cross bar 74, four connecting rods 71, two semi-arc rods 72, and two triangular telescopic rods 73. The four connecting rods 71 ​​are respectively fixed to the outside of both sides of the placement table 4, the two semi-arc rods 72 are respectively fixed to the bottoms of two adjacent connecting rods 71, and the two triangular telescopic rods 73 are respectively fixed to both sides of the top of the flip table body 1. The cross bar 74 is fixed between the telescopic ends of the two triangular telescopic rods 73. The top of the telescopic end of the triangular telescopic rod 73 is arranged in a triangular shape. The front side and the rear side of the top of the two semi-arc rods 72 are both provided with triangular grooves adapted to the triangular telescopic ends of the triangular telescopic rods 73. Through the arrangement of the above structure, the triangular grooves of the semi-arc rods 72 can move When the handlebar 71 is moved to the triangular telescopic rod 73, the triangular telescopic end of the triangular telescopic rod 73 will extend into the triangular groove of the semi-arc rod 72 under the elastic force of the triangular telescopic rod 73, so that the triangular telescopic rod 73 can limit the flipping position of the placement table 4 through the semi-arc rod 72, thereby accurately limiting the flipping angle of the placement table 4, thereby ensuring that the placement table 4 drives the supporting wheel side cover to achieve the precise position requirement each time it flips. Compared with the existing self-locking motor, the method of using the triangular telescopic rod 73 and the semi-arc rod 72 to limit the position is lower in cost than the self-locking motor. The self-locking motor usually requires complex electronic control systems and sensors to ensure accurate control and safety of the angle. These additional electronic components and equipment increase the cost.

[0032] During use, when the push column 53 approaches the inner wall of the supporting wheel side cover, the push column 53 will drive the suction cup 65 to contact the inner wall of the supporting wheel side cover first through the fixing plate 61 and the air pipe 63. Since the suction cup 65 and the U-shaped column 64 are rotating, the suction cup 65 will adapt to fit the inner wall of the supporting wheel side cover. At the same time, the inner wall of the supporting wheel side cover will push the suction cup 65 and the air pipe 63 in the opposite direction to drive the elastic folding bag 62 to stretch. The elastic folding bag 62 generates negative pressure at the suction cup 65 through the notch of the air pipe 63, so that the suction cup 65 is adsorbed and fixed to the inner wall of the supporting wheel side cover. The adsorption effect of the suction cup 65 can effectively fix the supporting wheel side cover on the placement table 4 to ensure that it will not move or shake during the processing. This stability is particularly important for precision processing operations and can ensure the accuracy and consistency of the processing.

[0033] When the placement platform 4 needs to drive the supporting wheel side cover to flip, the motor 2 is started, and the motor 2 will drive the placement platform 4 to rotate through the rotating rod 3, so that the placement platform 4 can realize the flipping operation of the supporting wheel side cover. During the rotation of the placement platform 4, the semi-arc rod 72 will be driven to rotate through the connecting rod 71. When the placement platform 4 rotates ninety degrees, the placement platform 4 drives the semi-arc rod 72 to rotate ninety degrees through the connecting rod 71. At this time, the triangular groove of the semi-arc rod 72 will move to the triangular telescopic rod 73. Under the elastic force of the triangular telescopic rod 73, the triangular telescopic end of the triangular telescopic rod 73 will extend into the semi-arc The triangular groove of the rod 72 allows the triangular telescopic rod 73 to limit the flipping position of the placement table 4 through the semi-arc rod 72, thereby accurately limiting the flipping angle of the placement table 4, thereby ensuring that the placement table 4 drives the supporting wheel side cover to achieve the precise position requirement each time it flips. Compared with the existing self-locking motor, the use of the triangular telescopic rod 73 and the semi-arc rod 72 to limit the position is lower in cost than the self-locking motor. The self-locking motor usually requires a complex electronic control system and sensors to ensure the precise control and safety of the angle. These additional electronic components and equipment increase the cost.
