Description

Technical Field

[0001] The utility model relates to the technical field of drilling auxiliary devices, in particular to a self-positioning drilling template for large steel structures. Background Art

[0002] Large steel structure refers to a building structure with a certain size, span and height, which uses steel as the main structural material. It is usually used in large buildings, bridges, marine engineering and other fields. The main characteristics of this structure include height, span, weight and construction difficulty.

[0003] When drilling on large steel structures, due to the large size and weight of the structure itself, as well as possible material inhomogeneity, deviations are prone to occur during the drilling process. This deviation not only affects the accuracy of the hole position, but may also pose a potential threat to the stability and safety of the entire structure. In addition, during the drilling process of large steel structures, the drill bit needs to continuously cut the workpiece material to form a hole. During this process, the drill bit will be subjected to cutting force and friction from the workpiece, which will cause wear and damage to the drill bit, especially when dealing with materials with higher hardness or greater toughness. This wear and damage will be more serious. In order to avoid this deviation, improve the accuracy of drilling, and extend the service life of the drill bit, it is necessary to use a drill jig to ensure that the drill bit can be accurately positioned at the predetermined position, so as to obtain an accurate and consistent hole position.

[0004] However, since large steel structures cannot usually be drilled using large drilling equipment, they are usually drilled using a handheld electric drill with a drill template directly installed on the drill. The operation process relies heavily on manual determination of the drilling target, and the position of the drill bit needs to be adjusted during the drilling process to align with the target position. When drilling holes in large steel structures, the drilling position may be relatively high, which brings more trouble to an environment that is already inconvenient for operation. The operator needs to ensure a stable position while also performing positioning and drilling, which is not conducive to practical applications. Utility Model Content

[0051] The following is a detailed description of the working principle of the self-positioning drilling template for large steel structures.

[0052] like Figure 1-Figure 6 As shown, before drilling, first mark the steel structure at the position where the hole needs to be drilled, and then place the entire device at the same longitudinal position of the mark according to the marked position, so that the cross frame 1 and the connecting plate 2 are close to the steel structure, and the two clamping plates 15 are respectively located on both sides of the steel structure. At this time, the bidirectional screw rod 13 can be rotated by turning the third knob 23, thereby driving the two sliders 14 to move toward the adjacent side, and driving the clamping plates 15 to perform centering clamping, so that the rubber block 22 moves toward the adjacent side, clamps the steel structure, and then fixes the device on the steel structure; after the device is fixed, the drilling template is at the same longitudinal position of the mark.

At this time, the electric drill bit can be passed through the drill template sleeve 17 to drill holes (in the above-mentioned overall positioning process, the movable plate 4 can be slid to one side of the horizontal frame 1 first, so as to visually observe the position of the mark, thereby facilitating alignment and positioning).

[0053] When the jig sleeve 17 needs to be replaced, the first screw rod 6 is driven to rotate by rotating the first knob 7, thereby causing the stop block 8 to move to the side away from the jig sleeve 17, thereby releasing the jig sleeve 17 and taking out the jig sleeve 17; then, a new jig sleeve 17 is inserted so that the jig sleeve 17 is elastically fixed under the action of the spring sheet 12 (it can only prevent it from falling down due to shaking or inversion, and cannot withstand greater force); and then, the first knobs 7 at both ends are rotated at the same time, so that the stop block 8 can move to the side close to the jig sleeve 17, thereby tightening the jig sleeve 17.

[0054] All the longitudinal and transverse directions recorded above refer to two directions on a plane formed by the transverse frame 1 as the horizontal axis and the connecting plate 2 as the longitudinal axis, wherein the longitudinal direction is the extension direction of the transverse frame 1 and the longitudinal direction is the direction perpendicular to the longitudinal direction.

[0055] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
