Description

Technical Field

[0001] This utility model belongs to the field of padlock hole grinding technology, and more specifically, relates to a padlock hole grinding device. Background Technology

[0002] Padlocks generally use a pin tumbler mechanism. This type of lock uses cylindrical pins to create obstacles inside the lock cylinder, preventing the lock cylinder from rotating and thus achieving the locking function. Padlocks mainly consist of the padlock body, lock cylinder, lock hook, pin tumbler assembly, and adapter. During the manufacturing process, the lock cylinder requires a positioning device in conjunction with a grinding device for polishing.

[0003] Currently, grinding padlock cylinders requires clamping and fixing the cylinder with a clamping plate, followed by grinding and deburring of the cylinder's openings using a grinding device. However, padlock cylinders are mostly irregular cylindrical structures. Existing clamping plates often cause the cylinder to vibrate and oscillate during grinding, resulting in low stability and affecting grinding quality. Furthermore, existing grinding devices require manual alignment, leading to low overall grinding efficiency. Utility Model Content

A slide rail and a push pin slidably mounted thereon, the push pin having a push end for pushing the lock cylinder in the limiting groove into the positioning assembly; the positioning assembly including a second slide rail, a positioning shaft slidably mounted thereon, and a swing drive, the positioning shaft having a positioning groove matching the lock cylinder, the swing drive driving the positioning shaft to swing to adjust the lock cylinder angle; and a grinding component including a third slide rail and a grinding head slidably mounted thereon, the grinding head having a grinding drill bit at its front end for multi-directional grinding of the lock cylinder opening position.

[0006] As a further improvement of this utility model, the limiting component also includes an alignment block, wherein an alignment cavity matching the lock cylinder is formed in the alignment block, which is used to buffer and align the lock cylinder that slides into the limiting groove.

[0007] As a further improvement of this utility model, the ejector assembly also includes a positioning block. The positioning block has a positioning protrusion at one end near the feeding groove. A limiting cavity matching the ejector end is opened in the middle of the positioning protrusion to limit the sliding path of the ejector pin.

[0008] As a further improvement of this utility model, the positioning shaft of the positioning component is connected to the swing block through a rotating shaft, and the swing block is linked to the output end of the swing drive through a linkage rod to realize the swing adjustment of the lock cylinder.

[0009] As a further improvement of this utility model, the third slide rail of the grinding component is configured as a vertical slide rail, and the grinding head slides along the third slide rail to adjust the grinding depth.

[0010] As a further improvement of this utility model, the table surface of the operating table is also provided with a horizontal slide rail, and the grinding part moves along the horizontal direction of the lock cylinder through the horizontal slide rail to complete multi-angle grinding.

[0011] As a further improvement of this utility model, the output end of the swing drive is connected to a rotating plate, and the rotating plate is hinged to the linkage rod through a fixing bolt, so as to convert the swing of the swing drive into the rotation of the positioning shaft.

[0012] As a further improvement of this utility model, the feeding trough is inclined, with its high end located below the grinding part and its low end extending to the outside of the operating table, for automatically exporting the grinding lock cylinder.
