Description

Technical Field

[0001] The utility model relates to the technical field of lead screw production, in particular to a fixed-section cutting device for lead screw production. Background Technique

[0002] A lead screw is a mechanical component that converts rotary motion into linear motion through corresponding components. Lead screws are commonly used in precision machinery industry for mechanical measurement and transmission operations. Due to the increasing requirements for the precision of parts in modern mechanical industry, the manufacturing of lead screws is also developing rapidly.

[0003] During the production of lead screws, a cutting device is often needed to cut the lead screws in order to obtain lead screws of the required length, which is convenient for the lead screws to be put into the equipment where they are needed for use.

[0004] However, it is found that in the existing cutting devices for lead screw production, when the lead screw is cut, it usually requires the operator to measure the length in advance, mark the position, and then cut the lead screw through the cutting component. This cutting method is cumbersome in operation, and cannot ensure that the length of each lead screw is the same, with low fixed-section precision. In the work of cutting multiple lead screws of the same length, the work efficiency is low.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0006] Aiming at the deficiencies and defects in the existing technology in the above background technology, that is, the existing cutting method is cumbersome in operation, and cannot ensure that the length of each lead screw is the same, with low fixed-section precision.

[0007] A fixed-section cutting device for lead screw production disclosed by the utility model includes a worm and a workbench. A worm gear is meshed on the outer surface of the worm. A gear is fixedly connected to the inner wall of the worm gear. A rack is meshed on the outer surface of the gear. A connecting rod is rotatably connected to the inner wall of the gear. A sliding block is fixedly connected to the outer surface of the connecting rod. A sliding groove is formed on the front surface of the workbench. The outer surface of the sliding block is slidably connected to the inner wall of the sliding groove. Equally spaced scales are formed on the upper surface of the workbench. A stop rod is fixedly connected to the upper surface of the sliding block.

[0008] Further, a rubber cushion block is fixedly connected to the upper surface of the stop rod, and an induction block is fixedly installed on the right side surface of the rubber cushion block.

[0009] Further, a limit shell is rotatably connected to the outer surface of the worm, and the outer surface of the limit shell is fixedly connected to the outer surface of the stop rod.

[0010] Further, the front surface of the workbench is fixedly connected to the back surface of the rack, and a guide plate is fixedly connected to the bottom surface of the workbench.

[0011] Furthermore, a first telescopic rod is fixedly installed on the upper surface of the workbench, and a limiting block is fixedly connected to the output end of the first telescopic rod.

[0012] Furthermore, two support blocks are fixedly connected to the upper surface of the workbench, a connecting block is slidably connected to the inner wall of the workbench, a second telescopic rod is fixedly connected to the outer surface of the connecting block, and the bottom surface of the second telescopic rod is fixedly connected to the upper surface of the workbench.

[0013] Furthermore, a motor is fixedly connected to the upper surface of the connecting block, and a cutting tool is fixedly connected to the output shaft of the motor.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By setting components such as a worm, a worm gear, a gear, a connecting rod, a sliding block, a rack, a scale, a stop rod, etc., when the worm is rotated, the worm is connected to the worm gear. At this time, the worm gear drives the gear to rotate, and the gear meshes with the rack. At this time, the gear moves under the limitation of the connecting rod and the sliding block, and the stop rod is driven to move by the sliding block. By opening a scale on the surface of the workbench, observing the position of the stop rod above the scale, and stopping the stop rod at the position to be set, the stop rod is limited under the action of the worm and the worm gear, thereby realizing the effect that the device can adjust the cutting length, facilitating fixed-section cutting, improving the fixed-section precision, and ensuring that the lead screw lengths of each section of cutting are the same.

[0016] 2. By setting components such as a rubber cushion block, an induction block, a guide plate, a limiting block, a support block, a cutting tool, etc., the guide plate is installed on the bottom surface of the workbench. Through the notch on the surface of the workbench, the cut lead screw is convenient to fall, and is transmitted through the guide plate, facilitating subsequent unified collection or processing of the lead screw. The rubber cushion block and the induction block are installed on the upper surface of the stop rod. When one end of the lead screw contacts the induction block, the first telescopic rod drives the limiting block to descend. Through the cooperation between the limiting block and the support block, the lead screw is limited. The second telescopic rod drives the connecting block to move, the connecting block drives the motor to move, the motor drives the cutting tool to rotate, and the cutting tool cuts the lead screw, thereby realizing that the device can ensure the stability during the cutting of the lead screw. And by setting the rubber cushion block, it is convenient to protect the induction block and prevent the induction block from being damaged due to too large impact force of the lead screw.
