Full-automatic multi-head tapping machine

Abstract

The invention discloses a full-automatic multi-head tapping machine which comprises a machine head assembly, a clamp, a supporting plate device and a guide rail device. The machine head assembly comprises a motor, a gear transmission device, an upper machine base, a lower machine base, a plurality of transmission rods and screw taps with the number corresponding to that of the transmission rods. The clamp comprises a clamp air cylinder, a first connecting rod mechanism, a first linkage rod, press strips and two first linkage rod seats. The two ends of the first linkage rod are connected with the two first linkage rod seats through bearings correspondingly. The press strips are fixed to the middle of the first linkage rod. The tail end of the first connecting rod mechanism and the end of the first linkage rod are fixed. The clamp air cylinder drives the first connecting rod mechanism, and therefore the press strips clamp or loosen a workpiece to be machined. The supporting plate device comprises a supporting plate and a supporting plate air cylinder, and the supporting plate is fixed to a piston rod of the supporting plate air cylinder. The guide rail device comprises two bevel guide rail plates and two limiting plates. The two bevel guide rail plates are fixed to a workbench, and the two limiting plates are located on the outer sides of the two bevel guide rail plates correspondingly. When the piston rod of the supporting plate air cylinder stretches out, the supporting plate is jointed with the tail ends of the bevel guide rail plates, support is provided for the workpiece to be machined, and the motor, the clamp air cylinder and the supporting plate air cylinder are controlled by a controller.

Description

technical field [0001] The invention relates to a fully automatic multi-head tapping machine. Background technique [0002] The current tapping machine structurally includes a frame, a workbench and a head assembly. The head assembly includes a motor, a feed shaft and a tap. The tap is directly connected to the feed shaft. When in use, when the head assembly goes down When the feed axis is pushed downwards, the tap is driven to move forward stably to tap on the workpiece to be processed; when the head assembly moves upwards, the feed axis is pulled upwards, and finally the tap is driven to withdraw from the workpiece to be processed. The head assembly of this structural tapping machine has a fixed structure, is only suitable for processing single-form workpieces, and has low production efficiency. When changing the workpiece to be processed, it is also necessary to change the corresponding fixture to meet the production needs, which increases the cost of production and proc...
