[0035] In the following, with reference to the accompanying drawings of specific embodiments of the present invention, the exemplary solutions of the embodiments of the present invention will be clearly and completely described. Unless otherwise defined, the technical terms or scientific terms used in the present invention should have the ordinary meaning as understood by those of ordinary skill in the art.
[0036] As Figures 1 - 3 shown, the auxiliary device for a flame cutting gun in this embodiment includes a support shaft 100, a sliding member, a rotating shaft 300, and a roller 400. The support shaft 100 is symmetrically provided with a first elongated hole 110 in the horizontal direction; the sliding member is slidably disposed in the first elongated hole 110 of the support shaft 100, and this sliding member is used to fix the cutting gun head; the rotating shaft 300 is fixedly disposed at one end of the support shaft 100 in the vertical direction, and the support shaft 100 rotates around the rotating shaft 300; the roller 400 is rotatably disposed at the other end of the support shaft 100. Place the auxiliary device for the flame cutting gun of the present invention on the steel plate, and the cutting gun head rotates around the rotating shaft with the distance from the rotating shaft to the sliding member as the radius to cut the circular steel plate.
[0037] As Figures 1 - 3 shown, the support shaft 100 is further provided with a second elongated hole 120, the second elongated hole 120 is arranged between the two first elongated holes 110, and the lengths of both are equal.
[0038] As Figures 4 - 6 shown, the sliding member includes a slider 200, the slider 200 is slidably disposed in the first elongated hole 110 of the support shaft 100; a positioning hole 200 is obliquely provided on the slider 200, and the positioning hole 230 communicates with the second elongated hole 120 of the support shaft 100, and this positioning hole 230 is used to insert the cutting gun head.
[0039] The sliding stroke of the slider 200 is the length of the first elongated hole 110. By adjusting the position of the slider 200 in the first elongated hole 110, the radius of the circular steel plate to be cut can be adjusted.
[0040] Optionally, the inclination angle of the positioning hole 230 is 30° or 45° or 60°, that is, the angle between the axis of the positioning hole 230 and the horizontal plane is 30° or 45° or 60°, and the specific angle can be adjusted according to actual production requirements. Therefore, there will also be a certain inclination angle around the circular steel plate cut by the fixed cutting gun head, which is convenient for the splicing use of the circular steel plate in subsequent production.
[0041] As Figure 4 and Figure 5 shown, the sliding member further includes a baffle 220, the baffle 220 is fixedly disposed on the rear side of the slider 200, and the height of the baffle 220 is greater than the diameter of the support shaft 100.
[0042] As Figure 4 and Figure 5As shown, a threaded hole 221 is formed in the baffle 220. The threaded hole 221 is perpendicular to and communicates with the positioning hole 230 of the slider 200. A tightening bolt 240 is screwed into the threaded hole 221.
[0043] As Figure 4 and Figure 5 shown, a screw rod 210 is fixedly provided on the front side of the slider 200, and a compression nut 250 is screwed onto the screw rod 210.
[0044] In actual production, after determining the position of the slider 200 in the first strip-shaped hole 110, rotate the compression nut 250 and cooperate with the baffle 220 to fix the slider 200 on the support shaft 100.
[0045] In actual production, after inserting the cutting gun head into the positioning hole 230, rotate the tightening bolt 240 until the cutting gun head is locked and fixed to prevent the cutting gun head from falling off during the cutting process and thus causing a safety accident.
[0046] As Figures 1 - 3 shown, one end of the support shaft 100 is provided with a rotating shaft hole 130 in the vertical direction and a first pin hole 140 in the front-rear direction, and the rotating shaft hole 130 and the first pin hole 140 are perpendicular and cross each other.
[0047] As Figures 1 - 3 and Figure 6 shown, the rotating shaft 300 is inserted into the rotating shaft hole 130 of the support shaft 100, and a second pin hole 310 is formed in the middle of the rotating shaft 300; a pin is used to pass through the first pin hole 140 and the second pin hole 310 to fixedly connect the support shaft 100 and the rotating shaft 300. To prevent the support shaft 100 from sliding between the support shaft 100 and the rotating shaft 300 when the support shaft 100 rotates along the rotating shaft 300.
[0048] As Figure 6 shown, a strong magnetic attraction ring 500 is sleeved on the lower end of the rotating shaft 300, and the rotating shaft 300 can rotate in the strong magnetic attraction ring 500.
[0049] Furthermore, as Figure 6 shown, the rotating shaft 300 and the strong magnetic attraction ring 500 are in clearance fit to ensure that the rotating shaft 300 can freely rotate within the strong magnetic attraction ring 500.
[0050] As Figure 1 and Figure 2 shown, the roller 400 is rotatably sleeved on the other end of the support shaft 100, and the roller 400 is fixedly connected to the support shaft 100 through a fixing nut 160 on its outer side to prevent the roller 400 from falling off the support shaft 100 during actual production.
[0051] Furthermore, the support shaft 100 and the roller 400 are in clearance fit to ensure that the roller 400 can freely rotate around the support shaft 100.
[0052] Furthermore, the second pin hole 310 and the center of the roller 400 are on the same horizontal plane, and the distance from the second pin hole 310 to the bottom end of the rotating shaft 300 is equal to the radius of the roller 400.
[0053] Optionally, an external motor fixed to the motor frame can be installed on the upper part of the rotating shaft 300. The output shaft of the external motor is connected to the rotating shaft 300 through a coupling, thereby driving the rotating shaft 300 to freely rotate in the strong magnetic attraction ring 500.
[0054] Furthermore, the support shaft 100, the slider 200, the rotating shaft 300, the roller 400 and the strong magnetic attraction ring 500 of the present utility model are all detachable structures, which are convenient for adjustment and easy to carry.
[0055] The working principle of this application is as follows:
[0056] Place the present utility model on the steel plate to be cut in the Figure 1 shown manner. At this time, the strong magnetic attraction ring 500 is stably adsorbed on the steel plate to be cut, and the position where the strong magnetic attraction ring 500 is located is the center of the circular steel plate to be cut; according to the radius of the circular steel plate to be cut, adjust the position of the slider 200 in the first strip-shaped hole 110; insert the cutting gun head into the positioning hole 230 and rotate the tightening bolt 240 to lock and fix the cutting gun head.
[0057] Start the switches of the flame cutting gun and the external motor. The flame cutting gun starts to cut the steel plate, and the external motor drives the rotating shaft 300 to rotate, thereby driving the support shaft 100 and the flame cutting gun to rotate together. After the support shaft 100 rotates one week, the cutting of the circular steel plate is completed. Turn off the switches of the flame cutting gun and the external motor, and then the circular steel plate can be removed.
[0058] Repeat the above steps and adjust the position of the slider 200 in the first strip-shaped hole 110 to achieve the cutting of circular steel plates of different sizes.
[0059] It should be noted that when there is an expression that one element is "connected", "coupled" or "linked" to another element, it may mean that they are directly connected, coupled or linked, but it should be understood that there may be intermediate elements between them; that is, it covers the positional relationship of direct connection and indirect connection.
[0060] It should be noted that the use of similar words such as "a" or "one" does not necessarily indicate a quantity limitation. Words such as "including" or "comprising" mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects.
[0061] It should be noted that terms indicating orientation or positional relationship such as "upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, which are for the convenience of describing the present utility model, rather than the device or element being referred to must have a specific orientation, be constructed and operated in a specific orientation; when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.
[0062] The preferred embodiments for implementing the present utility model have been described in detail above, but it should be understood that the functions of these embodiments are only for illustration, rather than limiting the scope, application or construction of the present utility model in any way. The protection scope of the present utility model is defined by the appended claims and their equivalent means.
