Screw locking machine

Abstract

The invention discloses a screw locking machine which comprises a machine frame, wherein a feeding mechanism, a three-shaft positioning mechanism, a locking mechanism and a product positioning mechanism are arranged on the machine frame. The screw locking machine provided by the invention can realize the continuous operation of the screw locking machine. The locking mechanism can position any point of the three-shaft positioning mechanism, thereby improving the accuracy and convenience of a locking process. Especially, the locking mechanism prevents a sliding table from generating a huge impact force during an automatic descending process, thereby avoiding scratching a machined part or damaging the threaded hole of the machined part, promoting the processing efficiency of the screw locking machine and reducing the damage rate of a to-be-locked product.

Description

technical field [0001] The invention relates to a screw locking machine. Background technique [0002] When assembling the screws on the product, the traditional manual tightening method is generally adopted, which wastes a lot of manpower and material resources, and the work efficiency is low. Later, with the rapid development of science and technology, locking tools such as electric screw machines and pneumatic screw machines gradually appeared, replacing the manual tightening method, improving work efficiency and reducing the work intensity of workers locking screws. However, the locking machine is equipped with various torque-limiting mechanisms, and it is difficult to grasp the firmness of screw tightening.

AI Technical Summary

Problems solved by technology

But the locking machine is equipped with a variety of torque-limiting mechanisms, and it is difficult to grasp the firmness of the screw tightening. If the force is small, it will easily fall off, and if the force is large, it will easily damage the workpiece.

[0003] However, when the sliding table of the locking machine slides downward, if the control is not accurate, the sliding table will go down too fast and too large, which will easily cause damage to the workpiece.

And in the process of tightening the screws, the electric bit is easy to scratch the shell of the workpiece, and the screw sucked by the electric bit cannot be connected with the screw hole on the workpiece, which will cause uneven force on the screw hole of the workpiece and lead to slippage, reducing the processing time. efficiency

[0004] And the locking machine in the prior art cannot realize the continuous supply of screws during work, or because the structure of the supply screw is relatively simple, the supply of screws is not timely, it is easy to cause the locking machine to have no screw locking, which reduces the processing efficiency and product quality. quality

The screwdriver head of the locking machine has a limited range of movement and inaccurate positioning, which is easy to cause damage to the locking product

There is only a fixed station under the screw bit. After the processing is completed, the product to be locked needs to be replaced, which reduces the processing efficiency and brings a lot of inconvenience to the user.
