Description

Technical Field

[0001] The present application relates to the technical field of tapping machines, and in particular to a material positioning mechanism of a servo tapping machine. Background Art

[0002] Tapping machines are used to tap nuts and other hardware parts, realizing automation to reduce labor costs and save costs. They are suitable for the processing of automotive parts and hardware. Tapping machines have the advantages of high speed and high precision. They can also tap perfect threads for thin plates, light alloys, synthetic resins and other soft products. At the same time, they can be equipped with multi-axis devices for multi-axis synchronous processing, which greatly improves production efficiency. Generally, in order to improve the tapping accuracy of the tapping machine, a clamping mechanism is used to clamp and fix the workpiece.

[0003] The existing Chinese patent with announcement number CN219703732U discloses a tapping machine with a positioning mechanism, including a base and a tapping machine body arranged at the top of the base, a transmission mechanism is arranged at the bottom of the base, a groove is arranged on the surface of the base, and a positioning mechanism for positioning and fixing the workpiece is arranged inside the groove. When the positioning mechanism and the transmission mechanism cooperate with each other, when the telescopic rod is in the gap between the two protrusions, the spring will drive the telescopic rod to move downward, which can drive the fixing sleeve to move downward, so that the linkage rod will flip again, which can drive the clamping block to move closer to the center, so as to achieve the clamping and positioning of the workpiece. Compared with traditional manual operation, it can improve the fixing effect of the workpiece, avoid the deviation of the workpiece during the processing, and ensure the processing of perfect threads.

[0004] However, the above-mentioned positioning mechanism has the following disadvantages: the device clamps and positions the workpiece by setting a positioning mechanism and a transmission mechanism, but when the device is processing, the workpieces need to be placed manually one by one between the positioning mechanisms, which wastes manpower, and the taps of the tapping machine body need to be selected according to the different workpieces. Traditionally, bolts and nuts are generally used for fixing, but this installation method is relatively complicated, and has certain skill requirements for the operator. It cannot be replaced quickly, which reduces work efficiency.

[0005] Therefore, we propose a material positioning mechanism for a servo tapping machine to solve this problem.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
