Description

Technical Field

[0001] This utility model relates to a ball assembly device for a recirculating ball steering gear with absolute error prevention function, belonging to the field of recirculating ball steering gear assembly technology. Background Technology

[0002] The recirculating ball steering gear contains multiple steel balls, and during assembly, a certain number of steel balls need to be installed into the recirculating ball steering gear using other equipment. Existing equipment for installing steel balls, such as the spiral raceway steel ball clamp disclosed in utility model patent CN 202412100 U, can meet the usage requirements to a certain extent, but it lacks a misplacement function, often resulting in incorrect steel ball assembly in the recirculating ball steering gear, leading to a high scrap rate. Therefore, it is necessary to develop a new steel ball assembly device to solve the above-mentioned problems existing in the current steel ball assembly method. Summary of the Invention

[0003] The purpose of this utility model is to provide a recirculating ball steering gear steel ball assembly device with absolute error prevention function that has a compact structure and ingenious design to solve the problem of high scrap rate in the existing recirculating ball steering gear steel ball assembly method.

[0004] The technical solution of this utility model is: A ball assembly device for a recirculating ball steering gear with absolute error prevention function includes a control seat, a lateral slide, a pressing rod, and a separating slide plate; characterized in that: the control seat is equipped with a lateral slide; a lifting plate is mounted on the bottom of the lateral slide via a lifting cylinder; a storage tube is mounted on the lifting plate; proximity switches A, B, and C are mounted on the storage tube; a pressing rod is mounted on the lateral slide above the storage tube via a pressing cylinder; the pressing rod is plugged into the storage tube; a separating slide plate is mounted on the lifting plate on one side of the storage tube via a separating cylinder; the separating slide plate is slidably connected to the storage tube.

[0005] The control base includes a base, a longitudinal cylinder, and a longitudinal slide; the longitudinal slide is slidably mounted on the base via the longitudinal cylinder and a guide rail; a transverse slide is slidably mounted on the longitudinal slide via a transverse cylinder and a guide rail.

[0007] The clearance hole A is equipped with a proximity switch A; the clearance hole B is equipped with a proximity switch B; and the clearance hole C is equipped with a proximity switch C.

[0008] The advantages of this utility model are: This ball assembly device for a recirculating ball steering gear with absolute error prevention is compact and ingeniously designed. It can detect the number of steel balls entering the storage tube through three sets of proximity switches.

[0011] The ball assembly device for the recirculating ball steering gear with absolute error prevention function includes a control seat 1, a lateral slide 2, a pressing rod 11, and a separating slide plate 13 (see the instruction manual appendix). Figure 1 and 2 ).

[0012] Control base 1 includes a base 14, a longitudinal cylinder 15, and a longitudinal slide 16; the longitudinal slide 16 is slidably mounted on the base 14 via the longitudinal cylinder 15 and a guide rail; a transverse slide 2 is slidably mounted on the longitudinal slide 16 via a transverse cylinder 17 and a guide rail (see the appendix of the instruction manual). Figure 1 and 2 During operation, the transverse cylinder 17, the longitudinal cylinder 15, and the longitudinal slide block 16 work together to drive the transverse slide block 2 to move in the transverse and longitudinal directions.

[0013] The control base 1 is equipped with a transverse slide 2; the bottom of the transverse slide 2 is equipped with a lifting plate 4 via a lifting cylinder 3. When the lifting cylinder 3 is working, it can drive the lifting plate 4 to move up and down.

[0014] The lifting plate 4 is equipped with a storage pipe 5 (see instruction manual). Figure 2 and 4 A ball-in branch pipe 18 is provided on one side of the storage pipe 5 (see attached instructions). Figure 6 During operation, the external steel ball output device can input a certain number of steel balls into the storage pipe 5 through the ball inlet branch pipe 18.

[0015] The storage pipe 5 on one side of the ball-in branch pipe 18 is provided with clearance holes A19 and B20 at intervals; the bottom end of the storage pipe 5 is provided with a separating sliding hole 21; the separating slide plate 13 is slidably connected to the separating sliding hole 21; the storage pipe 5 above the separating sliding hole 21 is provided with a clearance hole C9. A proximity switch A6 is installed on clearance hole A19; a proximity switch B7 is installed on clearance hole B20; a proximity switch C8 is installed on clearance hole C9 (see the appendix of the instruction manual). Figure 4 Proximity switches A6, B7, and C8 are purchased equipment, model number IME08-02BPSZT0S SICK.

[0016] The inner diameter of the storage tube 5 is the same as the diameter of the steel ball. When working, the steel ball enters the interior of the storage tube 5 and will stack together.

[0017] The distance between clearance holes A19 and B20 is equal to the diameter of the steel ball. The purpose of this setting is to ensure that when proximity switches A6 and B7 detect the steel ball but proximity switch C8 does not detect the steel ball during operation, it indicates that the number of steel balls entering the storage pipe 5 meets the requirements; otherwise, it does not.

[0018] A pressing rod 11 is mounted on the horizontal slide block 2 above the storage pipe 5 via a pressing cylinder 10; the pressing rod 11 is inserted into the storage pipe 5; a separating slide plate 13 is mounted on the lifting plate 4 on one side of the storage pipe 5 via a separating cylinder 12; the separating slide plate 13 is slidably connected to the separating slide hole 21 of the storage pipe 5.

[0019] When the ball assembly device of the recirculating ball steering gear with absolute error prevention function is working, the cooperation of the transverse cylinder 17, longitudinal cylinder 15, longitudinal slide 16 and transverse slide 2 can drive the storage tube 5 to move, so that its lower end corresponds to the assembly hole of the recirculating ball steering gear. Then the lifting cylinder 3 drives the lifting plate 4 to move down, so that the lower end of the storage tube 5 connects with the assembly hole of the recirculating ball steering gear.

[0020] After the above work is completed, the external steel ball output device can input a certain number of steel balls into the storage pipe 5 through the ball inlet branch pipe 18. At this time, if proximity switches A6 and B7 detect steel balls, but proximity switch C8 does not detect steel balls, it means that the number of steel balls entering the storage pipe 5 meets the requirements. Subsequently, the separator cylinder 12 drives the separator slide plate 13 to retract, allowing the steel balls to enter the circulating ball deflector under the action of gravity, thus completing the steel ball assembly work. If the number of steel balls entering the storage pipe 5 does not meet the requirements, the separator cylinder 12 will not operate. In this case, manual troubleshooting is required before operation can resume.

[0021] This ball assembly device for a recirculating ball steering gear with absolute error prevention is compact and ingeniously designed. It can detect the number of steel balls entering the storage tube 5 through three sets of proximity switches. If the number is incorrect, the ball assembly device will stop working, thus preventing errors. It is particularly suitable for the needs of assembling steel balls in a recirculating ball steering gear.
