Description

Technical Field

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

[0002] In many fields such as machinery manufacturing, hardware processing, and electronic component assembly, steel balls are often precisely stamped into the pre-set mounting holes of the workpiece to achieve core functions such as component positioning, rotational connection, and sealing and anti-slip. This process is one of the key links to ensure the assembly accuracy and performance of subsequent products.

[0003] Traditional implementation methods often rely on manual operation: operators need to hold simple tools such as punches and hammers, first manually place the steel ball at the positioning position of the mounting hole on the workpiece, and then gradually press the steel ball into the mounting hole by manually striking the punch. Manually completing the stamping operation of the workpiece takes a long time, and the operator is prone to fatigue, which leads to a decrease in operation speed. Therefore, in order to solve the above problems, this device proposes a steel ball stamping device. Utility Model Content

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] See attached document Figure 1-4 A steel ball stamping device includes: a stamping head 10, a connecting cylinder 20, a feeding assembly, and a stamping mechanism.

[0033] Specifically, the stamping head 10 has a stamping channel 11 inside. The stamping head 10 has a mounting groove that communicates with the inside of the stamping channel 11, and the connecting cylinder 20 is threaded into the mounting groove. A feeding assembly is mounted on the stamping head 10 to replenish steel balls into the stamping channel 11.

[0034] A stamping mechanism is mounted on the connecting cylinder 20. The stamping mechanism includes a stamping rod 31 and a driving component. The stamping rod 31 is movably mounted inside the connecting cylinder 20, and its bottom end is movably disposed inside the stamping channel 11. The driving component is mounted on the stamping rod 31 and is used to drive the stamping rod 31 to move in the vertical direction. When the driving component drives the stamping rod 31 to move downward, it can push the steel ball out of the stamping channel 11.

[0035] In one embodiment of this utility model, the feeding assembly includes a feeding pipe 40. The stamping head 10 has an inlet that communicates with the inside of the stamping channel 11. The outlet of the feeding pipe 40 is threaded into the inlet. The feeding pipe 40 is arc-shaped to facilitate the steel ball entering the stamping channel 11 by gravity. It should also be noted that when the stamping rod 31 is in the reset position, its bottom end is above the inlet of the stamping head 10, meaning the stamping rod 31 will not obstruct the steel ball from entering the stamping channel 11.

[0036] In one embodiment of this utility model, a limiting locking rod 41 is threaded onto the outer wall of the feeding tube 40. The limiting locking rod 41 can be used to temporarily block the continuous feeding of steel balls; that is, by rotating the limiting locking rod 41 clockwise, the bottom end of the limiting locking rod 41 is inserted into the interior of the feeding tube 40, thus preventing the steel balls on the left side of the limiting locking rod 41 from entering the stamping channel 11.

[0037] In one embodiment of this utility model, a magnetic block is installed at the bottom end of the stamping rod 31. When the steel ball enters the stamping channel 11, the magnetic block on the stamping rod 31 temporarily attracts the steel ball to the end of the stamping rod 31, thus temporarily fixing the steel ball. When the steel ball is stamped into the assembly groove of the workpiece, due to the large friction between the steel ball and the assembly groove, which is greater than the magnetic attraction force, the steel ball can separate from the magnetic block as the stamping rod 31 moves upward.

[0038] In one embodiment of this utility model, a spring 32 is sleeved on the outside of the stamping rod 31. The top end of the spring 32 presses against the top wall of the stamping rod 31, and the bottom end of the spring 32 presses against the inner bottom wall of the mounting groove. The spring 32 assists in the reset of the stamping rod 31, facilitating subsequent stamping of the steel ball. It should also be noted that the spring 32 is removable and replaceable. For replacement, simply rotate the stamping head 10 off the connecting cylinder 20 and then remove the spring 32 from the stamping rod 31.

[0039] In one embodiment of this utility model, the driving component includes a driving rod 30, a lead screw 50, and a cylinder 100; the driving rod 30 is fixedly connected to the top end of the stamping rod 31; the lead screw 50 is fixedly connected to the top end of the driving rod 30; and the telescopic shaft end wall of the cylinder 100 is connected to the top end of the lead screw 50. When stamping steel balls, the telescopic shaft of the cylinder 100 can be extended. After the cylinder 100 extends, it drives the lead screw 50, the driving rod 30, and the stamping rod 31 to move downwards. After the stamping rod 31 moves downwards, it causes the steel ball below the stamping rod 31 to move downwards inside the stamping channel 11, thereby ejecting the steel ball from the stamping channel 11.

[0040] In one embodiment of this utility model, a limiting sleeve 51 is threaded onto the lead screw 50, and a scale line is provided on the outer wall of the drive rod 30. The limiting sleeve 51 is used to limit the downward movement of the stamping rod 31, that is, the extreme position of the downward movement of the stamping rod 31 can be adjusted according to the depth of the assembly groove on the workpiece. The principle is as follows: when the stamping rod 31 moves downward, the drive rod 30 and the lead screw 50 also move downward synchronously. After the bottom end of the limiting sleeve 51 presses against the top end of the connecting cylinder 20, it limits the extreme position of the downward movement of the lead screw 50, thereby limiting the downward movement of the stamping rod 31.

[0041] In this embodiment, the working principle of the device is as follows: First, the workpiece to be processed is placed below the stamping head 10, and the assembly hole of the workpiece is aligned with the outlet of the stamping channel 11. Steel balls are added to the feeding pipe 40, and the steel balls fall into the stamping channel 11 by gravity through the feeding pipe 40. At this time, the stamping rod 31 is in the reset state, and its bottom end is located above the feed port, so it will not obstruct the entry of steel balls.

[0042] After the steel ball enters the stamping channel 11, it is attracted and fixed by the magnetic block at the bottom of the stamping rod 31, ensuring the accurate position of the steel ball before stamping. The cylinder 100 is activated, and its telescopic axis pushes the lead screw 50, drive rod 30 and stamping rod 31 downward as a whole. The stamping rod 31 presses the steel ball down along the stamping channel 11 into the assembly hole of the workpiece.

[0043] When the stamping reaches the desired depth, the limiting sleeve 51 contacts the top of the connecting cylinder 20, restricting the stamping rod 31 from moving further downward and preventing over-stamping. After stamping is completed, the cylinder 100 retracts, and the stamping rod 31 returns to its original position with the assistance of the spring 32, ready for the next stamping cycle.

[0044] The entire process achieves automatic feeding, positioning, stamping, and resetting of steel balls, thus improving stamping efficiency.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
