Description

Technical Field

[0001] This invention relates to the field of air spring controller assembly equipment, and more specifically to a steel ball pressing device for an air suspension controller valve body. Background Technology

[0002] Air suspension systems use air springs as elastic elements, utilizing the compressibility of gas to achieve their elastic effect. The compressed gas pressure can automatically adjust according to changes in load and road conditions. In this system, the controller is a crucial electrical component. The controller contains a valve body, and during valve body manufacturing, unavoidable extra holes are created. These extra holes need to be plugged with steel balls. Existing steel ball pressing equipment, such as the Chinese utility model patent with publication number CN220388556U, discloses an automatic steel ball riveting head, including: a drive assembly; a limiting assembly connected to the drive assembly; and a pressing head assembly connected to the limiting assembly. The drive assembly extends to drive the pressing head assembly to move vertically downwards to press the steel ball. The pressing head assembly is equipped with a spring. After pressing, the drive assembly retracts and then extends again to switch to riveting mode and drive the limiting assembly to limit the spring. The drive assembly continues to drive the pressing head assembly to move downwards to rivet the steel ball. In this steel ball pressing mechanism, when the pressure rod pushes the steel ball down, it needs to overcome the positioning bead. The positioning bead retracts and the steel ball falls, but at this time the steel ball is not yet placed stably, and the pressure rod immediately presses down, which makes the pressing effect and quality of the steel ball less than ideal.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0028] Example: A steel ball pressing device for an air suspension controller valve body, including a workbench 1, on which a conveyor line 2 runs through the entire workbench 1, as shown in the attached diagram. Figure 1 As shown, a transfer frame 3 for placing the controller valve body is installed on the conveyor belt of the conveyor line 2; the transfer frame 3 includes a disc body 31, as shown in the attached figure. Figure 3 As shown, symmetrical ribs 32 are installed on the disc body 31, and multiple support columns 33 are installed on the ribs 32. A circular groove 34 is located on the disc body 31 between the two ribs 32. The valve body is mounted on the two ribs, with its bottom end inserted into the circular groove. The support columns support the sides of the valve body to prevent interference from protruding parts on the valve body, thus ensuring stable placement of the valve body. Positioning holes 35 are arranged diagonally on the bottom of the disc body 31. The workbench 1 has multiple pressing stations 4. The conveyor line 2 is equipped with a frame lifting and positioning mechanism 5 for positioning the transfer frame 3, corresponding to each pressing station 4. Figure 2As shown; a robotic arm 6 for loading controller valve bodies is installed on the workbench 1, located between the pressing station 4 and the conveyor line 2. The robotic arm mainly loads the valve bodies, moving them from the transfer frame to the pressing station; the frame lifting and positioning mechanism 5 includes a cylinder fixing plate 51 mounted on the workbench 1, as shown in the attached figure. Figure 4 As shown, a lifting cylinder 52 is mounted on the cylinder fixing plate 51. The extended end of the lifting cylinder 52 is connected to a lifting frame 53. Positioning posts 54, which mate with positioning holes 35, are arranged diagonally on the lifting frame 53. Moving limit frames 57 are installed on the workbench 1 and on both sides of the conveyor line 2. When the lifting cylinder is activated, it drives the lifting frame upwards until the transfer frame contacts the moving limit frame. The positioning posts are engaged in the positioning holes at the bottom of the transfer frame, ensuring that the lifting frame can stably lift the transfer frame. Multiple fixing sleeves 55 are provided on the cylinder fixing plate 51 and around the lifting cylinder 52. Multiple guide posts 56, which mate with the fixing sleeves 55, are installed on the lifting frame 53. The stable operation of the lifting frame can be achieved through the cooperation of the guide posts and fixing sleeves. A positioning servo motor 16 is provided in the conveyor line 2 and at the corresponding pressing station 4. The extended end of the positioning servo motor 16 has a baffle 17 for limiting the position of the disc 31. The conveyor line is always in operation. After the transfer frame moves to the pressing station, the positioning servo motor drives the baffle to rotate. The transfer frame is blocked by the baffle and cannot move forward. Then the frame lifting positioning mechanism operates to lift the transfer frame.

[0029] The pressing station 4 includes a station frame 7 mounted on a workbench 1. A pressing base 8 is installed at the bottom of the station frame 7, and a clamping assembly 9 for fixing the controller valve body is installed on the front side of the pressing base 8. The clamping assembly 9 includes a movable plate 91 located on the front side of the pressing base 8, as shown in the attached figure. Figure 5 As shown, the movable plate 91 has a column 92 on its inner side, which is slidably connected to the pressing base 8. The pressing base 8 has a connector 93 on its front side. The movable plate 91 has a locking cylinder 94 on its outer side, as shown in the attached figure. Figure 6 As shown, the extended end of the locking cylinder 94 is connected to the connector 93; the inner side of the movable plate 91 is connected to the locking plate 95 via a slider assembly, and the inner side of the movable plate 91 is provided with a positioning block 96. The end of the locking plate 95 is connected to the positioning block 96 via an elastic element. The robotic arm sends the valve body to the pressing base. At this time, the robotic arm does not retract. The locking cylinder drives the movable plate to move towards the valve body. The locking plate at the upper end of the movable plate is in an elastic movable state. The upper end of the locking plate clamps the valve body. There are holes around the valve body. The robotic arm drives the valve body to change direction. The locking cylinder moves outward, the locking plate disengages from the valve body, and the valve body changes to the other side.

[0030] The upper end of the workstation frame 7 has a pressing power component 10, which mainly uses a motor to drive the screw to rotate, thereby raising and lowering the moving sleeve. The movable end of the pressing power component 10 is connected to a pressing top seat 11. The moving sleeve drives the pressing top seat to rise and fall. The end of the pressing top seat 11 is connected to a pre-pressing seat 12 via an elastic element. The pre-pressing seat 12 has a downward pressing channel 13. The lower part of the pressing top seat 11 is provided with a pressure rod 14 that extends into the downward pressing channel 13. The front end of the pre-pressing seat 12 has a steel ball guide assembly 15 for controlling the steel ball to enter the downward pressing channel 13. The upper end of the pre-pressing seat 12 has a positioning rod 18, which passes through the pressing top seat 11. A pre-compression spring 19 is sleeved on the positioning rod 18. The upper end of the pre-compression spring 19 is connected to the pressing top seat 11, and the lower end of the pre-compression spring 19 is connected to the upper end of the pre-pressing seat 12. The pre-top seat will first contact the valve body, and through the pre-compression spring, the pre-top seat will be tightly attached to the surface of the valve body. The pre-top seat 12 is provided with a guide seat 20 corresponding to the downward pressure channel 13. One side of the guide seat 20 is provided with an inlet 21 corresponding to the inlet end of the steel ball guide assembly 15. The lower part of the pre-top seat 12 is provided with a base seat 22 corresponding to the guide seat 20. The pressure rod 14 extends into the downward pressure channel 13. When the pre-top seat contacts the surface of the valve body, the base seat contacts the surface of the valve body. The discharge hole on the base seat is aligned with the hole on the surface of the valve body. After the steel ball enters into the guide seat, it falls through the base seat and enters the hole in the valve body.

[0031] The steel ball inlet assembly 15 includes an inlet cylinder 151 located on the rear side of the pressing top seat 11, as shown in the attached figure. Figure 7 As shown, the extended end of the feed cylinder 151 is connected to a switch plate 152, as per the attached diagram. Figure 8 As shown, the end of the switch plate 152 is slidably disposed in the pre-top seat 12, and the end of the switch plate 152 has a through groove 153 corresponding to the feed port 21; the feed port of the guide seat 20 is provided with a rib 154 for blocking the steel ball and cooperating with the through groove 153; the front side of the pre-top seat 12 is provided with a material tube seat 155, and a steel ball material tube 156 is provided in the material tube seat 155, the inner end of the steel ball material tube 156 cooperating with the through groove 153; the steel balls are arranged in sequence in the steel ball material tube. In the initial state, the rib is stuck in the through groove, preventing the steel ball from entering the guide seat. The feeding cylinder is started, driving the switch plate to move upward, the through groove and the rib are separated, and the steel ball enters the guide seat through the feed port. Then the feeding cylinder is reset. After the steel ball enters the hole of the valve body, the pressing power component continues to move, driving the pressure rod to pass through the guide seat and the base seat, enter the hole of the valve body, and press the steel ball into the valve body.

[0032] The working principle of this invention is as follows: The controller valve body is placed on a transfer frame, which is then conveyed to the pressing station via a conveyor line. The frame lifting and positioning mechanism lifts the transfer frame, separating it from the conveyor surface of the conveyor line. The transfer frame is then fixed at the corresponding pressing station. A robotic arm moves the valve body from the transfer frame to the pressing base. The clamping assembly fixes the valve body, and the pressing top seat moves onto the valve body under the drive of the pressing power component. The pre-pressing top seat contacts the valve body, the steel ball guiding component is activated, and the steel ball is sent into the pressing channel and enters the hole in the valve body. The pressing power component continues to work, and the pressing top seat continues to move downward. The pressing rod touches the steel ball and enters the hole, completing the pressing of the steel ball. Through the linkage between the pressing rod and the steel ball guiding component, after the steel ball is stably placed into the hole, the pressing rod then touches the steel ball to press it, achieving stable pressing of the steel ball and improving the pressing effect and quality.
