Description

Technical Field

[0001] This utility model relates to the field of steel ball pressing, specifically a pressing device for steel ball production. Background Technology

[0002] Steel ball pressing is generally done manually, which is labor-intensive and inefficient. To improve installation efficiency and accuracy, a corresponding pressing device is used to improve the pressing quality. A search of application CN2017211782.4 discloses a steel ball plug pressing device, which includes a cylinder assembly connected to a plunger via a floating connector. Two symmetrical adjustable limit screws on the plunger flange end are used to adjust the cylinder stroke, thereby controlling the pressing depth of the steel ball. A compression spring is pre-pressed inside the plunger via a pressure rod. The pre-pressure of this spring is the maximum pressing force required by the process. The pressure rod is connected to a pressing head, and a pressure device is installed between the pressure rod and the pressing head. A force sensor is used for pressing force detection. The steel ball falls onto the front end of the pressing head through a steel ball drop column. When not being pressed, the steel ball is stopped by a steel ball anti-detachment plunger to prevent it from falling freely. The pressing head is connected to a displacement sensor to detect the pressing displacement depth of the pressing head. This utility model improves the quality of steel ball pressing and realizes the setting and storage of pressing parameters to meet customers' requirements for quality traceability. However, the above description still has the following defects in actual use: This pressing device solves the problems of pressing force and pressing depth, but it cannot press steel balls into the shaft holes at both ends of some products, and it cannot adjust and position the pressing position. Therefore, it is necessary to design a pressing device with strong practicality for steel ball production. Utility Model Content
