DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] Example: Refer to Figure 1 , an auxiliary support plate frame structure for a plastic oil pump assembly platform, comprising an assembly platform 1, further comprising: an inclined bracket 2 and a second assembly base 3, wherein the inclined bracket 2 is fixedly mounted on the assembly platform 1, and the second assembly base 3 slides along the inclined bracket 2; When the second assembly base 3 slides downward, the second assembly base 3 moves toward the staff standing in front of the assembly table 1 , and when the second assembly base 3 moves upward, the second assembly base 3 moves away from the staff.

[0021] Reference Figure 1 The third assembly base 5 is rotatably provided on the second assembly base 3, and the second assembly base 3 is provided with a driving portion 4 for driving the third assembly base 5 to flip; the assembly fixture 6 is rotatably provided on the third assembly base 5, and during assembly, the cylinder shell of the plastic oil pump is fixed on the assembly fixture 6; When the driving part 4 drives the second assembly base 3 to move along the inclined bracket 2, the assembly fixture 6 follows the third assembly base 5 to flip, thereby flipping the barrel of the plastic oil pump fixed on the assembly fixture 6. When the second assembly base 3 rises and moves away from the staff, the third assembly base 5 drives the open end of the barrel of the plastic oil pump to flip toward the staff, so that the barrel mouth faces the staff. When the second assembly base 3 descends and moves toward the staff, the third assembly base 5 drives the barrel shell to flip upward, and finally the barrel mouth faces vertically upward. Therefore, in this embodiment, when assembling the plastic oil pump, the staff can more conveniently access the barrel shell of the plastic oil pump. Especially when it is necessary to install or debug parts in the cylinder shell, by flipping the cylinder shell, the number of times the workers have to bend or raise their heads can be reduced, thereby reducing labor intensity and improving work efficiency. At the same time, when adjusting the cylinder shell of the plastic oil pump, the cylinder shell moves toward the upper rear of the assembly table 1 while the shell opening of the cylinder shell is flipped toward the workers, so that by moving toward the lower front of the assembly table 1, the shell opening is flipped upward, thereby ensuring that the workers can better observe the internal assembly status of the cylinder shell when assembling the plastic oil pump, and at the same time, the shell opening is always facing a direction that is convenient for the workers to assemble the oil pump, further improving the convenience of the workers when assembling the oil pump.

[0022] Reference Figure 1 During transportation, the shell of the plastic oil pump is easily compressed and deformed, which makes it impossible to assemble the shell. For this reason, the auxiliary support plate frame structure for the plastic oil pump assembly station also includes a transmission component 7, which is arranged on the second assembly base 3, and the output end of the transmission component 7 is connected to the assembly fixture 6; when the second assembly base 3 moves backward and upward, the driving part 4 drives the open end of the shell of the plastic oil pump to flip toward the staff, and at the same time, the transmission component 7 drives the shell of the plastic oil pump to rotate; the adjustment component 8 and the roundness detection part 9, the adjustment component 8 is arranged on the third assembly base 5, and the roundness detection part 9 is arranged on the adjustment component 8. When the assembly fixture 6 rotates, the measuring end of the roundness detection part 9 conflicts with the inner wall of the shell of the plastic oil pump.

[0023] In this embodiment, when the second assembly base 3 slides along the inclined bracket 2, the transmission component 7 drives the third assembly base 5 to rotate, thereby driving the cylindrical shell of the plastic oil pump to rotate, and at the same time controls the roundness detection part 9 to contact the inner wall of the cylindrical shell through the adjustment component 8, so that the roundness detection of the inner wall of the cylindrical shell can be realized. Therefore, through the coordinated use of the transmission component 7 and the roundness detection part 9, the cylindrical shell can be comprehensively inspected for roundness during the flipping and rotation process. This detection method not only improves the efficiency and accuracy of the detection, but also reduces the risk of assembly failure caused by deformation of the cylindrical shell. Through real-time monitoring and feedback of the roundness detection part 9, deformation or damage problems of the cylindrical shell can be discovered and dealt with in a timely manner, which helps to ensure that the cylindrical shells of each batch of plastic oil pumps meet the quality standards, thereby improving the quality and reliability of the entire product.

The mounting rod 22 is fixedly installed on the first assembly base 21, playing a connecting and supporting role. The design of the mounting rod 22 takes into account the angle between it and the assembly platform 1 to ensure that the second assembly base 3 can slide along a suitable angle, so that the barrel mouth of the barrel shell of the plastic oil pump always remains in the optimal assembly position.

[0025] Reference Figure 3 and Figure 4 The second assembly base 3 includes a first mounting plate 34, which is slidably connected to the first guide rail 23.

After the output speed is reduced by the reducer 53, the output shaft of the reducer 53 drives the second transmission gear 54 to rotate, and the second transmission gear 54 drives the first transmission gear 52 to rotate, and the first transmission gear 52 drives the mounting bracket 51 to rotate, thereby adjusting the barrel mouth direction of the plastic oil pump barrel shell.

[0029] Reference Figure 5 and Figure 6 The assembly fixture 6 includes a three-jaw chuck 61 rotatably connected to the mounting frame 51, a chuck adjustment motor 62 is fixedly mounted on the side wall of the three-jaw chuck 61, the output shaft of the chuck adjustment motor 62 is fixedly connected to the adjustment knob of the three-jaw chuck 61, and a mounting shaft 63 is fixedly mounted on the bottom of the three-jaw chuck 61, and a first bevel gear 64 is fixedly mounted on the mounting shaft 63.

[0030] In this embodiment, the chuck adjustment motor 62 is started, and the chuck adjustment motor 62 drives the adjustment end of the three-jaw chuck 61 to rotate, thereby controlling the three-jaw chuck 61 to clamp or loosen the cylindrical shell.

[0031] Reference Figure 5-Figure 9 The transmission assembly 7 includes a fourth transmission gear 71 fixedly mounted on the side wall of the second side plate 32 and a rotating shaft 72 rotatably connected to the mounting frame 51.

[0032] When the axis of the cylindrical shell is parallel to the assembly platform 1 , the rotating shaft 72 rotates into the arc-shaped groove 33 .

[0034] The three-jaw chuck 61 drives the barrel shell to rotate around the axis of the barrel shell, thereby adjusting the deflection direction of the barrel mouth, thereby facilitating the installation of parts at different eccentric positions inside the barrel mouth.

[0035] Reference Figure 8 and Figure 9 The adjusting assembly 8 includes a connecting plate 81 fixedly connected to the mounting frame 51, a second guide rail 82 fixedly connected to the connecting plate 81, a slider 83 slidably connected to the second guide rail 82, a second screw rod 84 rotatably connected to the connecting plate 81, and the second screw rod 84 is threadedly connected to the slider 83.

[0036] In this embodiment, the second screw rod 84 is rotated to drive the slider 83 to slide up and down along the second guide rail 82, thereby adjusting the height of the roundness detection part 9 according to the length of the cylindrical shell.

[0037] When the roundness detection adjustment part is adjusted, drag the measuring hook 95, and then make the ball 96 contact the inner wall of the cylinder shell. During this process, the spring 93 contracts. During the rotation of the cylinder shell, the spring 93 drives the ball 96 to always contact the inner wall of the cylinder shell. At the same time, the laser ranging sensor 94 measures the distance between it and the slider 83. The measured data is used to drive whether the roundness of the cylinder is normal.

By introducing intelligent components such as the laser ranging sensor 94, real-time monitoring and feedback of the roundness of the cylinder shell are realized, further improving the efficiency and accuracy of detection.

[0039] Through real-time monitoring and feedback from the roundness detection unit 9, deformation or damage of the cylinder shell can be discovered and dealt with in a timely manner, thereby avoiding the risk of assembly failure due to deformation of the cylinder shell; by optimizing the structural design, such as the tilting bracket 2, the sliding base, the three-jaw chuck 61, etc., the convenience and efficiency of the assembly process are improved; by adjusting the position and angle of the cylinder shell and introducing intelligent components, the difficulty of observation and operation of the staff during the assembly process is reduced; through the design of the transmission component 7 and the adjustment component 8, the structure can adapt to cylinder shells of different lengths, thereby improving its scope of application and flexibility.
