An extrusion assembly is arranged on the fixing block. The extrusion assembly is connected with the bottom plate. The number of the extrusion assemblies is two. A first extrusion block and a second extrusion block are respectively installed on the two extrusion assemblies. A "Y"-shaped groove is formed in the first extrusion block, and a circular groove is formed in the second extrusion block.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0034] Such as Figure 1 and Figure 6As shown in the figure, the tapping tooling of the present utility model includes a fixing block 1, a positioning projection 2, a hinge 3, a buckle 4 and a positioning plate 5, which are used to fix the column rod 100 to facilitate tapping to form an internal thread hole 1000; the column rod 100 includes an end sleeve 1001 and a flange seat 1002;

[0035] As Figure 1 shown, a plurality of positioning holes 101 are provided on one surface of the fixing block 1, and tapping holes 102 are provided on the adjacent other surface; the axis of the tapping hole 102 is perpendicular to the axis of the positioning hole 101, and the tapping hole 102 communicates with the positioning hole 101; the positioning projection 2 is provided on the fixing block 1, and at least two positioning projections 2 are arranged around the positioning hole 101; a part of the column rod 100 is inserted into the positioning hole 101 and is clamped with the positioning projection 2;

[0036] In the above structure, when fixing the column rod 100, the end sleeve 1001 of the column rod 100 is inserted into the positioning hole 101. At this time, the flange seat 1002 will abut against the fixing block 1, and the hole of the flange seat 1002 will be sleeved on the positioning projection 2, so that the circumferential positioning of the column rod 100 is realized;

[0037] After that, the fixing block 1 and the column rod 100 are clamped by a fixture to realize the axial positioning of the column rod 100. Subsequently, drilling and tapping operations can be carried out on the column rod 100 through the tapping hole 102 with a drill bit and a screwdriver; it has the advantages of convenient positioning and convenient clamping of the column rod 100.

[0038] Specifically, circular chamfers are provided at the edges of the positioning hole 101 and the tapping hole 102, which can avoid personal injury caused by burrs at the edges during operation and prevent scratching of the column rod 100 at the same time.

[0039] As Figure 2 and Figure 3 shown, there are two fixing blocks 1, and positioning holes 101, tapping holes 102 and positioning projections 2 are provided on both fixing blocks 1; the two fixing blocks 1 are hinged by a hinge 3, and after the hinge 3 is unfolded, the positioning holes 101 of the two fixing blocks 1 are opposite;

[0040] In the above structure, in order to improve the convenience of clamping the column rod 100, there are two fixing blocks 1. In this way, after the column rod 100 is inserted into the positioning holes 101 of the two fixing blocks 1, the two fixing blocks 1 are combined, and the axial positioning of the column rod 100 is realized. After that, it is clamped by a fixture and tapping work can be carried out.

[0041] Specifically, the axial length of the part of the column rod 100 protruding outside the positioning hole 101 is X; after the hinge 3 is unfolded, the distance between the two fixing blocks 1 is X or 2X;

[0042] In the above structure, the protruding part of the column rod 100 is actually the flange seat 1002. X is the axial length of the flange seat 1002. When the distance between the two fixing blocks 1 is X, only one fixing block 1 needs to be inserted into the column rod 100, and the other is used for abutting and positioning; when the distance is 2X, the column rod 100 is inserted into both fixing blocks 1.

[0043] Furthermore, this tooling further includes a clamping assembly that clamps and fixes the two fixing blocks 1.

[0044] First, the clamping assembly is a buckle 4. The male buckle and the female buckle of the buckle 4 are respectively arranged on one fixing block 1 to relatively fix the two fixing blocks 1.

[0045] In the above structure, when fixing the two fixing blocks 1, they are connected and fixed by the buckle 4, which has the advantage of being convenient to open and close and can realize the quick disassembly and assembly of the column rod 100.

[0046] Second, the clamping assembly is a bench vice; after inserting the fixing block 1 into the column rod 100, it can be clamped and fixed by the bench vice.

[0047] As Figure 4 shown, the positioning plate 5 is arranged on the fixing block 1, and the positioning plate 5 is arranged opposite to the positioning hole 101.

[0048] In the above structure, the positioning plate 5 is arranged opposite to the positioning hole 101, and the positioning plate 5 is arranged on both fixing blocks 1. After the two fixing blocks 1 are combined, the two positioning plates 5 will expand to both sides. In this way, when clamping with the bench vice, the positioning plate 5 can be lapped on the top surface of the bench vice to realize the positioning work and ensure that this tooling is in a horizontal state to prevent deviation during drilling and tapping.

[0049] As Figure 1 shown, the fixing block 1 is in a cuboid structure, and a plurality of positioning holes 101 and tapping holes 102 are arranged in a linear array on the fixing block 1.

[0050] In the above structure, the fixing block 1 is set in a cuboid structure and the positioning holes 101 are arranged in a linear array, which is convenient for the two fixing blocks 1 to be docked, so that the tapping holes 102 are on the same surface, facilitating the subsequent drilling and tapping operations.

[0051] Specifically, the fixing block 1 and the positioning protrusion 2 are of an integral structure.

[0052] Specifically, the fixing block 1 and the positioning protrusion 2 are made of aluminum alloy. The positioning holes 101, tapping holes 102 and positioning protrusion 2 can be formed by milling on the aluminum alloy profile, which has the advantages of light weight and easy operation.

[0053] In some embodiments, as Figure 5As shown, a limiting rod 6 and an elastic gasket 7 are also provided;

[0054] Specifically, when the two fixing blocks 1 are docked, the distance between them is greater than 2X. At this time, the elastic gasket 7 is used for compensation. The limiting rods 6 are provided on both of the two fixing blocks 1, and the length is half of the distance between the two fixing blocks 1. In this way, when the two fixing blocks 1 are docked, the two limiting rods 6 will abut against each other, and at the same time, the elastic gasket 7 abuts against the column rods 100 on the two fixing blocks 1, so as to ensure the stability of the column rods 100, which can avoid damage to the column rods 100 caused by over-clamping during clamping.

[0055] Specific implementation steps:

[0056] Insert the end sleeve 1001 of the column rod 100 into the positioning hole 101. At this time, the flange seat 1002 will abut against the fixing block 1, and the hole of the flange seat 1002 will be sleeved on the positioning protrusion 2, so that the circumferential positioning of the column rod 100 is realized;

[0057] After that, the fixing block 1 and the column rod 100 are clamped by a fixture to realize the axial positioning of the column rod 100. Subsequently, drilling and tapping operations can be carried out on the column rod 100 through the tapping hole 102 with a drill bit and a screwdriver.

[0058] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
