Description

Technical Field

[0002] A lead screw, also known as a screw, is a mechanical transmission component that converts rotational motion into linear motion, or converts linear motion into rotational motion. It is mainly composed of a screw, a nut, and a ball (a ball screw has a ball, but an ordinary lead screw does not). For example, in a machine tool, the rotation of the lead screw can allow the tool or workbench to perform precise linear motion to achieve processing of the workpiece. In an elevator, the rotation of the lead screw can allow the platform to rise or fall smoothly.

A method for using a cutting device for screw rod processing, using the cutting device for screw rod processing according to claim 6, characterized in that: The steps include: Step 1: Start the hydraulic cylinder (917) to adjust the distance between the sliding frame 1 (905) and the sliding frame 2 (906) according to the length of the screw rod to be cut, and initially fix and clamp the screw rod through the feeding module (9), and then start the motor 1 (702) to clamp the screw rod stably and appropriately through the fixing module (7); Step 2: After the fixing is completed, the hydraulic rod (3) and the cutting machine (4) are started to cut off the screw rod, and the splashing slag is blocked by the collection bin (801). At the same time, the negative pressure pump (803) is started to keep the inside of the collection box (802) and the collection bin (801) in a negative pressure state, so as to collect the slag generated by the cutting; Step 3: After the cutting is completed, the motor 1 (702) rotates in the opposite direction to release the fixation of the screw rod, and at the same time, the hydraulic cylinder (917) is started to make the sliding frame 1 (905) and the sliding frame 2 (906) approach each other, and one end of the screw rod is clamped by the clamping block (908). The hydraulic cylinder (917) is started again to push the sliding frame 1 (905), driving the screw rod to return to the cutting position to complete the loading.
