DETAILED DESCRIPTION

[0020] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0021] Example 1

[0022] like Figures 1 to 2 As shown, an angle steel welding positioning fixture provided by an embodiment of the present invention is used to fix three angle steels 1 into a triangular frame structure. Two adjacent angle steels 1 are connected by a connecting plate 2. The angle steel 1 welding positioning fixture includes a fixture table 3 and three positioning components installed on the fixture table 3. The three positioning components are respectively located at the triangular positions of the triangular frame structure. Each positioning component includes an end positioning piece 4 and at least one outer frame positioning piece 5 and a pressing positioning piece. The end positioning piece 4 is in contact with two adjacent angle steels 1 and the connecting plate 2 connecting the two angle steels 1.

[0023] Among them, this embodiment not only realizes the positioning of the three corners of the triangular frame structure through the end positioning members 4, but also realizes the positioning between the connecting plate 2 and the angle steel 1. In addition, in order to prevent the connecting plate 2 from being displaced, this embodiment is also provided with a connection positioning member. In addition, this embodiment also limits the outer edge position of the angle steel 1 through the outer frame positioning member 5. Each positioning assembly of this embodiment includes two frame positioning members, thereby realizing the restriction of the external size of the triangular frame, so that the size of each guide frame end frame after welding is uniform, and the occurrence of defective products is avoided.

[0024] The end positioning member 4 may be a baffle-shaped structure or a block-shaped structure having two contact surfaces 6. When it is a block-shaped structure, any contact surface 6 contacts the end of the angle steel 1 and the connecting block.

[0025] The clamping positioning part of this embodiment includes a clamping plate 7 and a limiting bolt 8. The limiting bolt 8 is threadedly connected to the clamping table 3. The clamping plate 7 is provided with a making way groove for the limiting bolt 8. The connecting plate 2 is pressed against the angle steel 1 by the clamping plate 7, thereby achieving the fixation of the connecting plate 2 and the angle steel 1.

[0026] The connection positioning member of this embodiment is a positioning protrusion 9 fixedly connected to the fixture table 3 , and a positioning hole 10 cooperating with the positioning protrusion 9 is formed on the connection plate 2 .

[0027] In some other embodiments, the fixture table 3 is rotatably mounted on the base, which makes it easier for workers to rotate the fixture table 3 during welding, thereby enabling workers to complete welding work at different positions at a fixed position, which is more flexible.

[0028] In some other embodiments, in order to make the movement of the welding positioning fixture safer and more portable, hanging rings (not shown in the figure) are fixedly installed at the four corners of the fixture table 3.

[0029] Example 2

[0030] like Figure 3-Figure 5 As shown, an embodiment of the present invention provides a welding positioning fixture for angle steels 1, which is used to fix three angle steels 1 into a triangular frame structure. Two adjacent angle steels 1 are connected by a connecting plate 2. The welding positioning fixture for angle steels 1 includes a fixture table 3 and three positioning components installed on the fixture table 3. The three positioning components are respectively located at the triangles of the triangular frame structure. Any positioning component includes an end positioning piece and at least one outer frame positioning piece and a pressing positioning piece. The end positioning piece is in contact with two adjacent angle steels 1 and the connecting plate 2 connecting the two angle steels 1.

[0031] In this embodiment, the end positioning members not only realize the positioning of the three corners of the triangular frame structure, but also realize the positioning between the connecting plate 2 and the angle steel 1. In addition, this embodiment also limits the outer edge position of the angle steel 1 through the outer frame positioning members. Each positioning assembly of this embodiment includes two frame positioning members, thereby realizing the restriction of the external dimensions of the triangular frame, so that the dimensions of each guide frame end frame after welding are uniform, and the occurrence of defective products is avoided.

[0032] The clamping and positioning member of this embodiment is a quick clamp 17, the fixing portion of which can abut against the connecting plate 2, thereby fixing the connecting plate 2 and the angle steel 1 on the clamp table 3, facilitating subsequent welding work. In addition, the quick clamp 17 is an existing structure, so it will not be described here in detail.

[0033] To accommodate changes in raw material dimensions and the wear of the end positioning members and outer frame positioning members over time, which can reduce precision, the end positioning members of this embodiment include a first fixing seat 11 and two end positioning blocks 12 detachably mounted on the first fixing seat 11; while the outer frame positioning members include a second fixing seat 13 and an outer frame positioning block 14 detachably mounted on the second fixing seat 13.

[0034] The two end positioning blocks 12 are in contact with the ends of the two angle steels 1 respectively, and the two outer end positioning blocks 12 are in contact with the corresponding connecting blocks, thereby realizing the end positioning function;

[0035] The end positioning block 12 and the outer frame positioning block 14 can be replaced, thereby ensuring the yield rate of the guide frame end and reducing material waste;

[0036] In some other embodiments, the end positioning block 12 and the outer frame positioning block 14 are detachable in a manner of being fixed with bolts;

[0037] In some other embodiments, the detachable manner is as follows: the end positioning block 12 and the outer frame positioning block 14 are both connected to a T-block 15, and the fixing seat 11 and the fixing seat 2 13 are provided with corresponding T-slots 16, and the purpose of quick replacement is achieved through the cooperation of the T-slots 16 and the T-slots 16;

[0038] In some other embodiments, the fixture table 3 is rotatably mounted on the base, which makes it easier for workers to rotate the fixture table 3 during welding, thereby enabling workers to complete welding work at different positions at a fixed position, which is more flexible.

[0039] The specific rotation installation method is as follows: a fixed shaft (not shown) is fixedly installed on the base, and a hole is opened at the center of the clamp table 3 to cooperate with the fixed shaft, so that the clamp table 3 can be rotated. In addition, a nut can be threadedly connected to the fixed shaft to fix the clamp table 3.

[0040] In some other embodiments, in order to make the movement of the welding positioning fixture safer and more portable, hanging rings (not shown in the figure) are fixedly installed at the four corners of the fixture table 3.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit and essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
