Description

Technical Field

[0001] The utility model relates to the technical field of plasma cutting, in particular to an angle-adjustable strong magnetic adsorption type plasma cutting gauge. Background Art

[0002] Plasma cutting is a tool that uses the high temperature of a plasma arc to cut metal. It achieves the purpose of cutting by generating a plasma arc between the cutting torch and the workpiece, causing the metal to partially melt and then using high-speed airflow to displace the molten metal.

[0003] There are many disadvantages when using a plasma cutter for manual cutting: the positioning mechanism and magnetic attraction mechanism of the existing cutting gauge fixing seat are set separately, and these two mechanisms need to be adjusted separately during use, which is cumbersome. In addition, manual cutting requires the use of various auxiliary tools, making it difficult to control the cutting speed and torch height, affecting the concentration of the plasma arc and the distribution of the cutting power, and easily leading to defects such as uneven surface and uneven cuts on the cut workpiece, thereby reducing the cutting quality and failing to meet the quality requirements of surface processing. In addition, when the cutting surface is a vertical or inclined plane, the cutting difficulty and low efficiency lead to long operation time and high labor intensity for the operator. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a magnetic plasma cutting gauge with adjustable angle, which solves the problems of inconvenient use of the existing cutting gauge positioning mechanism and low surface processing quality, as well as the difficulty and low efficiency in cutting on vertical or inclined surfaces, resulting in long operation time and high labor intensity for the operator.

[0029] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0030] like Figure 1 An angle-adjustable magnetic plasma cutting gauge includes a fixed sleeve 1 for securing the cutting nozzle and a cutting distance adjustment assembly 3 for adjusting the cutting range. The cutting distance adjustment assembly 3 is fixed to the workpiece surface via a magnetic attraction mechanism 4. The left end of the cutting distance adjustment assembly 3 is connected to the fixed sleeve 1, and a multi-dimensional adjustment assembly 2 is disposed between the fixed sleeve 1 and the cutting distance adjustment assembly 3.

[0031] Specifically, if Figure 1, the fixed sleeve 1 is provided with a clamping assembly for tightening the cutting nozzle to keep the cutting nozzle stable. The cutting distance adjustment assembly 3 includes more than two connecting rods 3-1, which can be used by connecting multiple connecting rods 3-1 end to end to expand the cutting range of the cutting gauge. The connecting rod 3-1 is also provided with a scale to facilitate adjusting the cutting distance. The left end of the connecting rod 3-1 is fixed with a multi-dimensional adjustment assembly 2 through an adapter 5. A connecting sleeve 3-2 is provided on the connecting rod 3-1. Preferably, the length of the connecting sleeve 3-2 is 5 cm. The connecting sleeve 3-2 can enhance the stability of the connecting rod 3-1, eliminates the need for a separate support assembly, and improves the cutting efficiency and quality of the cutting gauge on uneven workpiece surfaces. The left end of the connecting sleeve 3-2 is provided with a first locking piece 3-3 for locking the connection between the connecting rod 3-1 and the connecting sleeve 3-2 to prevent them from loosening during operation.

[0032] Preferably, the connecting rod 3 - 1 and the connecting sleeve 3 - 2 are both made of stainless steel.

[0033] like Figure 2 , the magnetic mechanism 4 is fixed to the surface of the cutting workpiece through a magnetic base 4-4, and the magnetic base 4-4 includes a strong magnetic block 4-5 fixed in the groove at the bottom of the magnetic base 4-4 and a deep groove ball bearing 4-2 fixed in the bearing groove at the top of the magnetic base 4-4. The top surface of the magnetic base 4-4 is flush with the top surface of the deep groove ball bearing 4-2. Four threaded through holes are evenly distributed on the circumference of the flange of the groove, and the strong magnetic block 4-5 is fixed in the groove by countersunk bolts. Furthermore, an arc-shaped groove is provided at the bottom of the strong magnetic block 4-5 to avoid non-removable protrusions that may exist near the sample punching. The presence of these protrusions will cause the magnetic base 4-4 to be unable to fully fit with the workpiece plate, affecting the cutting accuracy and quality.

[0034] like Figure 2 A guide hole is provided in the center of the magnetic base 4-4, and a positioning plunger 6 is connected to the inner thread of the guide hole. In order to ensure the coaxiality of the magnetic base 4-4 and the strong magnetic block 4-5, the positioning plunger 6 passes through the main body of the magnetic base 4-4 and then passes through the strong magnetic block 4-5. Figure 3 The bottom of the positioning plunger 6 is provided with a cavity that accommodates a spring 6-1 and a pin 6-2. The pin 6-2 is connected to the top wall of the cavity via the spring 6-1. The bottom of the pin 6-2 is hemispherical and is retractably disposed within the cavity. The top of the positioning plunger 6 is provided with a hexagonal blind hole.

[0035] like Figure 2A magnetic connector 4-1 is connected to the top of the magnetic base 4-4. The bottom of the magnetic connector 4-1 is integrally formed with a rotating shaft 4-3 that is interference-fitted with the deep groove ball bearing 4-2. Under the action of the deep groove ball bearing 4-2, the magnetic connector can flexibly rotate on the magnetic base 4-4. The magnetic connector 4-1 is provided with a through hole for the connecting sleeve 3-2 to pass through. The magnetic connector 4-1 is slidably connected to the connecting sleeve 3-2. A second locking member 4-6 is provided on the side of the magnetic connector 4-1 for locking the position of the magnetic connector 4-1 and the connecting sleeve 3-2.

[0036] like Figure 4 The multi-dimensional adjustment assembly 2 includes an adjustment unit with inner cavities at its left and right ends for accommodating steering heads 2-4. The spherical steering heads 2-4, when adjusted together with the adjustment unit, enable multi-dimensional angle adjustment of the cutting nozzle, thereby expanding the applicability of the device. The left end of the multi-dimensional adjustment assembly 2 is fixedly connected to the right end of the fixed sleeve 1 via a steering head 2-4, while the right end is fixedly connected to the left end of the connecting rod 3-1 via another steering head 2-4, forming a flexible adjustment structure that facilitates adjustment of the cutting angle.

[0037] Preferably, the adjustment portion of the multi-dimensional adjustment assembly 2 comprises a first plate 2-1 and a second plate 2-2 arranged vertically, connected by an adjustment member 2-3. Circular stop holes are provided at each end of the first plate 2-1 and the second plate 2-2, respectively, to engage the steering head 2-4. Because the steering head 2-4 is spherical, loosening the adjustment bolt allows the steering head 2-4 to rotate multi-dimensionally between the first and second plates 2-1, 2-2. After adjusting the cutting angle, tighten the adjustment bolt.

[0038] During installation, align the pin 6-2 of the positioning plunger 6 with the guide hole at the top of the magnetic base 4-4. Use a hexagonal wrench to screw the positioning plunger 6 into the guide hole. By rotating the hexagonal wrench, you can adjust the position of the positioning plunger 6 within the guide hole, thereby changing the length of the pin 6-2 of the positioning plunger 6 protruding from the bottom of the guide hole to accommodate the different depths of the sample punch. Next, press the deep groove ball bearing 4-2 into the bearing slot, and then press the rotating shaft 4-3 at the bottom of the magnetic connector 4-1 into the inner ring of the deep groove ball bearing 4-2, ensuring that it can flexibly rotate around the rotating shaft 4-3. Finally, assemble the assembled magnetic mechanism 4, fixed sleeve 1, multi-dimensional adjustment component 2, and cutting distance adjustment component 3.

[0039] When using this device to assist in cutting a circular workpiece, first create a sample hole at the center of the circle. Then, insert the pin 6-2 of the positioning plunger 6 into the sample hole. Engage the bottom surface of the strong magnetic block 4-5 with the workpiece's cutting surface. Adjust the cutting distance and secure the cutting nozzle in the fixed sleeve 1. The operator, holding the cutting torch and aided by a cutting gauge, can quickly and stably cut the circular workpiece. The strong attraction between the strong magnetic block 4-5 and the workpiece ensures that the pin 6-2 remains within the sample hole, ensuring accurate and stable positioning and preventing unevenness or blemishes on the cut surface.

[0040] When cutting on a vertical or inclined surface, first securely attach the magnetic base 4-4 to the workpiece's cutting surface. Next, adjust the length and angle of the cutting distance adjustment assembly 3, and then adjust the multi-dimensional adjustment assembly 2 to maintain the desired angle between the cutting nozzle and the workpiece. Activating the cutting gauge allows for beveling of various angles, such as 30°, 45°, and 60°, on vertical or inclined surfaces.

[0041] When cutting a cylinder, secure it firmly to the workbench to prevent displacement during cutting. Adjust the cutting path of the cutter gauge based on the cylinder's diameter and the desired cut size. Then, adjust the multi-axis adjustment assembly 2 to position the cutting nozzle at the desired angle and position before starting the cutter gauge.

[0042] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
