Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention discloses a machine for drilling center holes in the plane of a lifting lug, comprising a base 2, a housing 1, and a cover 9. The base 2 is provided with a positioning groove 4, and a positioning seat 3 is provided in the positioning groove 4. One end of the housing 1 is vertically mounted on the positioning seat 3. The interior of the housing 1 is recessed with a plurality of limiting grooves 11 that match the outer contour of the lifting lug 10. The lifting lug 10 is inserted into each of the limiting grooves 11. The cover 9 is located on the outside of the housing 1 and abuts against the open end face of the housing 1. The inner side of the housing 1 also abuts against the end face of the lifting lug 10. A positioning plate 8 is installed on the end of the cover 9 facing the base 2. The other end of the positioning plate 8 is bent to form a positioning part, which abuts against the base 2.

[0023] One end of the cover is mounted on the housing via a hinge, and the hinge is close to the base, allowing the cover to open and close with the hinge as the center.

[0024] In this embodiment, the bottom surface of the positioning seat 3 is provided with a slot, and the bottom surface of the base 2 is provided with an insertion port opposite the slot. An insertion rod 12 is provided in the insertion port. One end of the insertion rod 12 is inserted into the slot, and the other end extends to the outside and is fitted with a pressure plate 6. A compression spring 7 is fitted on the exposed part of the insertion rod 12. One end of the compression spring 7 is installed on the base 2, and the other end is installed on the pressure plate 6.

[0025] In this embodiment, support seats 5 are installed on both sides of the base 2. The support seats 5 are arranged in an "L" shape and each support seat 5 is provided with screw holes. Bolts can pass through the screw holes to fix the device on the platform of the drilling machine.

[0026] In this embodiment, the positioning groove 4 and the positioning seat 3 are arranged in a "T" shape, which can position the positioning seat after insertion; the slot, the socket and the insertion rod 12 are all arranged in a rectangular shape, which can position the pressure plate and avoid the circumferential rotation of the pressure plate, and the positioning seat can be positioned by the insertion rod.

[0027] In this embodiment, the housing 1 and the cover 9 are made of steel, which increases robustness and service life.

[0028] In this embodiment, adjacent lifting lugs 10 are not in contact with each other, allowing them to be suspended in the air, which facilitates the passage of the drill rod.

[0029] The housing is configured with multiple housings. Therefore, when one housing is installed on the base, the other housing can be opened and the lifting lugs can be inserted into the limiting groove. This allows the lifting lugs inside the previous housing to be directly replaced after installation, and the processing operation can continue, greatly increasing efficiency.

[0030] When in use, insert the ear hook into the limiting groove of the housing and press down the pressure plate. The movement of the pressure plate drives the insertion rod. After the insertion rod moves out of the insertion port, the positioning seat on the housing can be inserted into the positioning groove of the base. After it moves into place, release the pressure plate. The rebound of the compression spring can push the pressure plate and the insertion rod upward, so that the insertion rod can automatically insert into the slot with the positioning seat, thereby positioning the positioning seat and the housing.

[0031] As the housing moves onto the base, the positioning part on the positioning plate will abut against the top surface of the base. By squeezing, the housing cover can be closed and abut against the open end face of the housing and the end face of the lifting lug, thereby pressing and positioning the inserted lifting lug.

[0032] This device can be installed on the platform of a drilling machine. The drill rod on the drilling machine can drill through multiple lifting lugs in one go from top to bottom. Since the lifting lugs are suspended and do not contact each other, it is convenient for the drill rod to penetrate. The iron filings produced during drilling can enter between the lifting lugs, preventing the iron filings from jamming the drill rod.

[0033] After drilling is completed, the pressure plate is pressed down again, and the shell is taken out. After the shell cover is no longer blocked by the positioning plate, the shell cover can be opened directly, and the internal lifting lugs can be emptied directly, which facilitates disassembly and assembly.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
