[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] First Embodiment

[0026] Please refer to the following: Figure 1 , Figure 2 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a circular cover bolt fastening auxiliary clamp provided by this utility model; Figure 2 for Figure 1The diagram shows another structural view. A circular cover bolt fastening auxiliary clamp includes: a connector 2, which is disposed on the top of the mounting bracket 1;

[0027] A fixing plate 3 is disposed on the top of the connector 2, and a limiting groove 31 is formed inside the fixing plate 3.

[0028] Multiple fasteners 11 are provided inside one side of the mounting bracket 1.

[0029] The shape of the limiting groove 31 is adapted to the shape of the circular cover to be tightened.

[0030] The fastener can be a bolt, suction cup, or other device that can fix the mounting bracket to the workbench; by using the fastener, the mounting bracket can be firmly fixed in the appropriate working position, avoiding displacement during the tightening of the round cover bolts, and providing a stable foundation for subsequent operations;

[0031] The shape of the limiting groove is adapted to the shape of the round cover to be fastened. This design allows the round cover to be accurately embedded in the limiting groove when placed. Taking a common round cover as an example, the inner diameter, depth and edge shape of the limiting groove are designed according to the size and outline of the round cover to ensure that the round cover will not easily wobble after being placed.

[0032] The working principle of the circular cover bolt fastening auxiliary clamp provided by this utility model is as follows:

[0033] First, use the fastener 11 to fix the mounting bracket 1 in a suitable working position. Then, place the circular cover to be tightened into the limiting groove 31. Because the shape of the limiting groove 31 matches the shape of the circular cover, the circular cover can be accurately placed and will not easily wobble. Next, the operator uses tools to tighten the bolts on the circular cover. The limiting groove 31 limits the circular cover, ensuring its stability during tightening, making it easier for the operator to apply torque steadily, and improving the accuracy and efficiency of bolt tightening.

[0034] Compared with related technologies, the circular cover bolt fastening auxiliary clamp provided by this utility model has the following beneficial effects:

[0035] The mounting bracket 1 is fixed by the fastener 11, and the circular cover is limited by the limiting groove 31, which allows the operator to apply force more stably when tightening the bolts. Compared with manual tightening by hand, the torque is easier to reach the specified range, which effectively reduces the quality risk caused by insufficient or excessive torque and improves the product assembly quality.

[0036] Second Embodiment

[0037] Please refer to the following: Figure 3 and Figure 4 Based on the first embodiment of this application which provides an auxiliary clamp for fastening circular cover bolts, the second embodiment of this application proposes another auxiliary clamp for fastening circular cover bolts. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0038] Specifically, the difference in the second embodiment of this application regarding the auxiliary clamp for fastening a circular cover bolt is that, in the auxiliary clamp for fastening a circular cover bolt, a plurality of positioning tubes 5 are fixedly installed on the top of the mounting frame 1, a magnetic plate 51 is fixedly installed on the bottom of the inner side of the positioning tube 5, a positioning post 52 is magnetically attracted to the top of the magnetic plate 51, and an installation groove 4 is provided inside the connector 2.

[0039] The positioning tube 5 is disposed on the inner side of the mounting groove 4.

[0040] The top of the positioning post 52 is fixedly installed on the bottom of the fixing plate 3.

[0041] The working principle of the circular cover bolt fastening auxiliary clamp provided by this utility model is as follows:

[0042] When the fixing plate 3 needs to be installed, align the positioning post 52 at the bottom of the fixing plate 3 with the positioning tube 5. The positioning post 52 will be quickly and accurately installed in place under the magnetic attraction of the magnetic plate 51. When the fixing plate 3 needs to be replaced, simply overcome the magnetic attraction between the magnetic plate 51 and the positioning post 52 to remove the fixing plate 3.

[0043] Compared with related technologies, the circular cover bolt fastening auxiliary clamp provided by this utility model has the following beneficial effects:

[0044] The positioning tube 5, magnetic plate 51, and positioning post 52 work together to facilitate the user's disassembly of the fixing plate 3 during use. This allows the fixing plate 3 to be replaced according to different sizes of round cap bolts. This design improves the versatility of the fixture, enabling it to adapt to the tightening of various specifications of round cap bolts, reducing the company's production costs and improving production efficiency.

[0045] Third Embodiment

[0046] Please refer to the following: Figure 5 Based on the first embodiment of this application which provides an auxiliary clamp for fastening circular cap bolts, the third embodiment of this application proposes another auxiliary clamp for fastening circular cap bolts. The third embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the third embodiment will not affect the separate implementation of the first embodiment.

[0047] Specifically, the difference in the circular cover bolt fastening auxiliary clamp provided in the third embodiment of this application is that a protective pad 6 is fixedly installed on the inner side of the limiting groove 31 of the circular cover bolt fastening auxiliary clamp.

[0048] The working principle of the circular cover bolt fastening auxiliary clamp provided by this utility model is as follows:

[0049] During the process of placing the circular cover into the limiting groove 31 and tightening the bolts, the protective pad 6 is always in contact with the surface of the circular cover to prevent the inner side of the limiting groove 31 from directly scratching the surface of the circular cover.

[0050] Compared with related technologies, the circular cover bolt fastening auxiliary clamp provided by this utility model has the following beneficial effects:

[0051] The protective pad 6 effectively protects the surface of the circular cover, preventing scratches and wear during assembly, thus improving the product's appearance quality and overall quality, and reducing product defects caused by appearance flaws.

[0052] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
