Description

Technical Field

[0001] This utility model relates to the field of steel ball pressing, and in particular to a steel ball pressing device. Background Technology

[0002] Press-fitting steel balls is a common mechanical assembly process, mainly used to press steel balls (usually made of high-carbon steel or stainless steel) into holes or grooves in workpieces to form an interference fit, achieving functions such as positioning, sealing, or load transfer. The combination of springs and steel balls in press-fitting (such as spring plungers and elastic positioning mechanisms) is widely used in precision machinery, automated equipment, and consumer electronics due to its unique elastic positioning + rigid contact characteristics. However, the efficiency of manually pressing springs and steel balls is currently too low, and designing highly automated production lines for the combination of springs and steel balls is too complex and costly, making it impossible to design an automated line for every workpiece, thus limiting its versatility.

[0005] Furthermore, a rotary telescopic cylinder is provided on the inclined surface. The rotary telescopic cylinder is located on the side of the limiting component. The movable end of the rotary telescopic cylinder is provided with a rotary telescopic head. The rotary telescopic head rotates and extends to directly above the workpiece to press and fix the workpiece.

[0018] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the utility model "a steel ball pressing device" is provided in conjunction with the accompanying drawings.

[0019] See Figure 1 and Figure 2 In this embodiment, the steel ball pressing device includes a base 100, on which a ramp 101 is provided. A limiting member 103 is provided on the inclined surface 102 of the ramp 101 to position the workpiece. An assembly cylinder 104 is provided at the bottom end of the inclined surface 102. An assembly cylinder 105 is provided at the movable end of the assembly cylinder 104 to hold steel balls and springs. The assembly cylinder 105 faces upward along the inclined surface 102 toward the workpiece. In use, the workpiece is installed on the limiting member 103, and then the steel balls and springs are placed into the assembly cylinder 105 in sequence. Since the assembly cylinder 105 faces upward along the inclined surface, the steel balls and springs will automatically fall into the assembly cylinder 105 under the action of gravity, which is convenient for operation. Then, the assembly cylinder 104 is activated to assemble the steel balls and springs into the workpiece. After that, the workpiece is replaced, and the above assembly operation is repeated. This device has a simple structure, low cost, and different limiting members 103 can be designed for different workpieces. It has strong versatility and can greatly improve assembly efficiency compared to manual assembly.

[0020] See further Figure 2 In this embodiment, a rotary telescopic cylinder 106 is provided on the inclined surface 102. The rotary telescopic cylinder 106 is located on the side of the limiting member 103. A rotary telescopic head 107 is provided on the movable end of the rotary telescopic cylinder 106. The rotary telescopic head 107 rotates and extends to directly above the workpiece to press and fix the workpiece, preventing the workpiece from shifting and damaging the workpiece during pressing, thereby improving pressing efficiency and pressing quality.

[0021] More specifically, in this embodiment, a buffer 108 is provided at the bottom of the rotary telescopic head 107. The buffer 108 is preferably a spring sheet or a sponge. When the rotary telescopic head 107 presses down to fix the workpiece, the buffer 108 will form a buffer between the bottom of the rotary telescopic head 107 and the workpiece, preventing the bottom of the rotary telescopic head 107 from rigidly contacting the workpiece and protecting the surface of the workpiece from wear.

[0022] See further Figure 1 In this embodiment, the bottom end of the limiting member 103 is provided with a through groove 109. The assembly cylinder 105 slides along the through groove 109 to press the workpiece. The through groove 109 guides the pressing position of the assembly cylinder 105 to press the workpiece, ensuring that the workpiece can be accurately pressed.

[0023] More specifically, in this embodiment, the limiting member 103 is also provided with a magnetic suction member 110. The magnetic suction member 110 is located below the extension line of the through groove 109. In this way, when the assembly cylinder 105 extends to press the workpiece, the assembly cylinder 105 will pass directly above the magnetic suction member 110. The magnetic suction member 110 will magnetically attract and stabilize the steel ball and the spring, ensuring that the steel ball and the spring will not be misaligned during assembly, thereby improving the quality of workpiece pressing.

[0024] Furthermore, in this embodiment, both the assembly cylinder 104 and the rotary telescopic cylinder 106 are electrically connected to the central controller to achieve linkage between the assembly cylinder 104 and the rotary telescopic cylinder 106. After the assembly cylinder 104 has finished pressing, the rotary telescopic cylinder 106 actively lifts and rotates open, making it convenient for the operator to remove the pressed workpiece and put in a new workpiece to be pressed, ensuring the continuity of the pressing process and further improving the pressing efficiency.
