[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0023] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0026] Combined with Figure 1 and 2 In this embodiment, a laser irradiation structure for auxiliary positioning on a magnetic base drilling rig is fixed on the magnetic base, including a base 1 fixedly connected to the magnetic base by screws, a circular hole 2 and at least one laser lamp 3 arranged around the circular hole 2 are provided on the base 1, and the laser lamp 3 is arranged on the upper end surface of the base 1 and inclined toward the center of the circular hole 2. The laser lamp 3 irradiates a marking point at the center of the circular hole 2, that is, the center position of the desired drill hole, thereby realizing the drilling positioning function. The laser lamp 3 irradiates on the bottom surface to form a pattern such as dots, lines, or a cross cursor, or a combination of multiple laser irradiations to form an indicating cursor.

[0027] As a preferred solution of the utility model, a plurality of laser lamps 3 are arranged around the circular hole 2 on the base 1. The plurality of laser lamps 3 are arranged in a circle with the center of the circular hole 2 as the center. When the marking points formed by the plurality of laser lamps 3 are not in the same position, it indicates that the positioning function fails and needs to be repaired in time to avoid drilling in the wrong position, thereby playing a warning function.

[0028] As a preferred solution of the utility model, a boss is provided on the upper end surface of the base 1, and a laser lamp mounting hole 4 for mounting the laser lamp 3 is provided on the boss. Both ends of the laser lamp mounting hole 4 are open in design. A laser emission hole is provided at one end of the laser lamp mounting hole 4 so that the light of the laser lamp 3 can pass through. The opening size of this end is smaller than the diameter of the laser lamp 3. A laser lamp assembly hole is provided at the other end to facilitate the disassembly and assembly of the laser lamp 3.

[0029] As a preferred solution of the utility model, a threaded plug 5 is connected to the laser lamp assembly hole of the laser lamp mounting hole 4, and an internal thread is provided on the inner wall of the laser lamp mounting hole 4 at one end away from the laser lamp mounting hole 4. The threaded plug 5 is arranged along the axis of the laser lamp mounting hole 4 and is threadedly connected to the base 1 to fix the axial position of the laser lamp 3.

[0030] As a preferred solution of the utility model, threaded adjustment parts 6 are provided on the upper and lower sides of the laser lamp mounting hole 4, and threaded through holes for assembling the threaded adjustment parts 6 are provided on the boss and the base 1. The threaded adjustment parts 6 are arranged along the radial direction of the laser lamp mounting hole 4 and are threadedly connected to the base 1. The threaded adjustment parts 6 on the upper and lower sides respectively abut against the upper and lower sides of the laser lamp 3, so that the angle of the laser lamp 3 can be adjusted to adapt to the processing error. In order to ensure the flexibility of adjusting the angle of the laser lamp 3, the upper and lower heights of the laser lamp mounting hole 4 can be appropriately enlarged. On this basis, rubber pads can be set on the upper and lower inner walls of the laser lamp mounting hole 4.

[0031] As a preferred solution of the present utility model, the threaded plug 5 and the threaded adjustment member 6 are both existing threaded fasteners such as screws.

[0032] As a preferred solution of the utility model, a cable 9 is connected to the base 1 through a cable wiring hole 7 and a cable connector 8. A wire trough 10 and a wire outlet hole 11 are provided on the base 1. The wire trough 10 is provided on the lower end surface of the base 1 and passes through all the laser lamp mounting holes 4. The wire trough 10 is connected to the cable wiring hole 7, and the wire outlet hole 11 is connected to the laser lamp mounting hole 4 and the wire trough 10. The wires of the laser lamp 3 are led out through the wire trough 10 and are conductively connected to the cable 9.

[0033] As a preferred solution of the utility model, a sealing strip 12 is embedded in the wire trough 10 , and the sealing strip 12 is a rubber strip used to protect the wires in the wire trough 10 .

[0034] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
