Description

Technical Field

[0002] With the rapid development of electronic products, the processing of chip parts on sockets needs to improve production efficiency and ensure production quality. In particular, some processing equipment often needs to be modulated according to the products and work requirements during the production process to adapt to workpieces of different specifications and shapes, thereby improving the flexibility and adaptability of the production line. However, due to the limitations of size specifications and the fixed installation structure, the structure of the traditional tapping machine cannot be customized and adjusted according to actual needs, and it is difficult to adapt to workpieces of different specifications and shapes; and the traditional tapping machine may produce large vibrations and shocks during movement, affecting the processing accuracy and equipment life, and the tapping machine requires a large load intensity for the motor when it moves up and down, resulting in high energy consumption and low equipment operation efficiency.

[0003] For example, application number CN202321383316.4 discloses a tapping machine, including a machine body, a tap, a detector, an automatic cleaning device, a brush, a mounting frame and a driving cylinder structure. The detector is used to automatically detect the effective tapping depth of the tap to ensure that the controller will output normal processing information only after the effective tapping depth of the tap reaches a preset depth. It is used to accurately detect the tapping depth, has high processing efficiency, and can effectively prevent defective products. However, there are defects such as large driving force and high energy consumption when the tapping machine moves downward as a whole, and large vibration and impact may be generated during operation, affecting the life of the machine; application number CN20212342192 8.1 discloses a tapping machine, including a supporting base, a central control touch screen, a vibrator, a vibration plate, a straight vibrator, a guide groove, a chopping plate, a tapping machine, a mounting chassis, a discharge port, a servo motor and a toggle mechanism structure. By providing the guide groove and the chopping plate, the processed products can be neatly arranged through the vibration plate and the guide groove and sent to the inside of the chopping plate, so that the workpiece can be processed by the tapping mechanism, and the processed workpiece can be pushed to the inside of the discharge port, so as to realize the automation of workpiece tapping production, save labor and improve production efficiency. However, there is a defect that the tapping machine may generate large vibration and impact during movement, which affects the processing accuracy and equipment life.

[0004] Therefore, the above two utility model patents both disclose a tapping machine. When producing and processing product parts, the tapping machine may generate large vibrations and impacts during movement, affecting the processing accuracy and equipment life. In addition, when the tapping machine moves up and down, the motor needs to have a large load intensity and high energy consumption. Utility Model Content

Place the product to be tapped on the upper surface of the storage table 501 connected to the arm member 306 on the positioning sleeve rod seat 305 and define the position, and start the servo motor 401, the cylinder barrel 302 and the photoelectric sensor 1010 at the same time, then the cylinder barrel 302 and the piston 301 When starting, the seal 304 sleeved on the telescopic rod 303 is pushed to drive the rod sleeve connecting block 307 to move downward, and the first hinge block 205 connected to the rod sleeve connecting block 307 moves downward in the limit plate 204, so that the chain 202 in the double-ear hinge block 201 rotates around the gear shaft 203, and the second hinge block 206 at the other end of the chain 202 is pulled by the pulling force of the first hinge block 205 to pull the gravity block 108 to sleeve on the limit rod 109, so that the motor drive device 4 inside the seal 304 moves downward as a whole.
