Description

Technical Field

[0001] The utility model relates to the technical field of drill rod processing, in particular to a cutting device which is easy to fix. Background Art

[0002] Oil drill pipe is a steel pipe with a threaded tail end, which is used to connect the surface equipment of the drilling rig and the equipment or bottom hole device at the bottom of the drilling rig. The purpose of drilling is to transport drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit.

[0003] In the production and processing of oil drill pipes, the raw material pipes need to be cut and processed according to the product size required by the customer. When the raw material pipes are hoisted onto the cutting table for cutting, the traditional cutting equipment is relatively simple in structure, and the staff needs to manually adjust the center and press for auxiliary fixation. The size of the oil drill pipe is generally large, which makes the staff very strenuous and inconvenient. At the same time, during continuous cutting, the large mass makes it difficult to push and feed the materials. The cutting tables with some simple clamping structures need to be loosened first and then clamped again when pushing the materials, which greatly reduces the cutting efficiency. Therefore, we propose a cutting equipment that is easy to fix to solve the above problems. Utility Model Content

[0006] Preferably, two groups of slide grooves are provided at the inner upper end of the fixed frame, and two groups of sliders are fixedly connected to the lower end of the movable frame. The sliders are respectively slidably connected to the inside of the slide grooves, and the lower ends of the sliders are rotatably installed with multiple groups of evenly distributed balls, and the lower ends of the balls are in contact with the bottom of the slide grooves.

[0007] Preferably, a reduction motor is fixedly installed at the middle of the lower end of the cutting table, the output end of the reduction motor is fixedly connected to a transmission shaft, and the front and rear ends of the transmission shaft are both fixedly sleeved with second bevel gears.

The threaded rod 8 can be driven to rotate by the rotation of the worm wheel 11. The moving member 9 can be driven to move linearly by the rotation of the threaded rod 8. The movement of the moving member 9 can make the slide bar 10 drive the moving frame 3 to move synchronously, so that the positioning roller 7 can clamp and fix the two ends of the raw material tube through the movement of the moving frame 3. Due to the special shape of the positioning roller 7, raw material tubes of different sizes can be fixed through the distance adjustment operation. At the same time, no manual fixation is required, which saves time and effort and is very convenient. The raw material tube is supported by the positioning roller 7 to achieve a suspended effect, and the positioning roller 7 can rotate. When the contact area with the raw material tube is small, the raw material tube can be moved relatively easily without the need for loosening operation, that is, the raw material tube can be directly and easily pushed to move while clamping and fixing. Finally, the raw material tube can be cut by opening the saw blade cutting machine 20, which greatly improves the processing efficiency.

[0023] Two groups of slide grooves 4 are arranged at the upper end of the fixed frame 2, and two groups of sliders 5 are fixedly connected to the lower end of the movable frame 3.

[0024] When the moving frame 3 is moving, the slider 5 and the slide groove 4 play a limiting role, which is more stable. At the same time, the support by the ball 6 can greatly reduce the friction between the structures and increase the service life.

[0025] A reduction motor 14 is fixedly installed at the middle of the lower end of the cutting table 1, and a transmission shaft 15 is fixedly connected to the output end of the reduction motor 14.

The support rollers 21 provide support during the process of hoisting the raw material pipe, and then the raw material pipe is centrally fixed by subsequent positioning rollers 7.

[0028] Working principle:

[0029] When the raw material pipe is hung on the cutting table 1 by using the hanger, the transmission shaft 15 can be driven to rotate by turning on the reduction motor 14, and the second bevel gear 16 can be driven to rotate by the rotation of the transmission shaft 15, and the third bevel gear 18 can be driven to rotate by the rotation of the second bevel gear 16, and the third bevel gear 18 can be driven to rotate by the rotation of the rotating shaft 17, and the fourth bevel gear 19 can be driven to rotate by the rotation of the rotating shaft 17, and the first bevel gear 13 can be driven to rotate by the rotation of the fourth bevel gear 19, and the worm 12 can be driven to rotate by the rotation of the first bevel gear 13, and the worm 12 can be driven to rotate by the rotation of the worm 12, and the worm wheel 11 can be driven to rotate by the rotation of the worm wheel 11, and the threaded rod 8 can be driven to rotate by the rotation of the threaded rod 8.

The end is clamped and fixed. Due to the special shape of the positioning roller 7, raw material tubes of different sizes can be fixed by adjusting the distance operation. At the same time, no manual fixation is required, which saves time and effort and is very convenient. In this process, when the movable frame 3 is moving, the slider 5 and the slide groove 4 play a limiting role, which is more stable.
