DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, the utility model provides a technical solution: an auxiliary device for flange assembly, including a concave seat 1, and a plurality of groups of T-shaped blocks 104 are equidistantly fixedly installed on one side of the bottom of the concave seat 1, and the T-shaped blocks 104 correspond to the T-slots 301. Because the T-shaped blocks 104 are provided, after the T-slots 301 are stuck on the surfaces of the corresponding T-shaped blocks 104, it is ensured that the placement rack 3 will not slide at will when it is fixed to the bottom of the concave seat 1.

[0023] A rotating plate 101 is rotatably installed on the top of both sides of the concave seat 1, and a connecting rod 102 is fixedly installed at one end between the two groups of rotating plates 101, and a roller 103 is rotatably installed on the surface of the connecting rod 102. By providing the rotating plate 101 and the connecting rod 102, after the flange 4 is clamped inside the placement rack 3, the rotating plate 101 is controlled to rotate so that the connecting rod 102 and the roller 103 are clamped on the surface of the flange 4, ensuring that the flange 4 will not roll at will when it is clamped on the top of the placement rack 3.

[0024] A clamping mechanism 2 is fixedly installed at one end of the bottom of both sides of the concave seat 1. The clamping mechanism 2 includes two sets of mounting plates 201, and mounting columns 202 are fixedly installed on the top of the mounting plates 201, and end plates 203 are fixedly installed on the top of the mounting columns 202. A clamping spring 205 is provided on the surface of the mounting columns 202, and a clamping plate 204 is slidably installed on the surface of the two sets of mounting columns 202 located between the clamping spring 205 and the end plate 203. Because the clamping plate 204 and the clamping spring 205 are provided, the clamping plate 204 is pressed to make the clamping plate 204 slide down on the surface of the mounting column 202, so that the placement rack 3 can be slidably inserted into the bottom of the concave seat 1. The clamping plate 204 is loosened and the clamping plate 204 is lifted up under the rebound action of the clamping spring 205, so that the placement rack 3 is clamped and fixed to the bottom of the concave seat 1.

[0025] A plurality of sets of placement racks 3 are provided at the bottom of the concave seat 1. A rectangular groove 303 is provided on one side of the bottom of the placement rack 3. Position-limiting sliding grooves 304 are symmetrically provided on both sides of the rectangular groove 303. A first positioning block 305 is fixedly installed at the bottom of the rectangular groove 303. A sliding block 306 is slidably installed at the top of the rectangular groove 303. Since the sliding block 306 is provided, the sliding block 306 is controlled to extend or retract into the rectangular groove 303, so as to facilitate the clamping, fixing, storage or taking of the flange 4.

[0026] A second positioning block 307 is fixedly installed at the bottom of the sliding block 306, and the second positioning block 307 corresponds to the first positioning block 305. A return spring 308 is provided between the first positioning block 305 and the second positioning block 307. By providing the return spring 308, the sliding block 306 is pressed to make the return spring 308 squeeze and deform between the first positioning block 305 and the second positioning block 307, ensuring that the return spring 308 will not be misplaced when squeezed and deformed. At the same time, the return spring 308 can lift the sliding block 306 to clamp and fix the flange 4;

[0027] Limiting protrusions 309 are symmetrically fixedly installed at the bottom of both sides of the sliding block 306, and the limiting protrusions 309 correspond to the limiting slide grooves 304. A group of limiting protrusions 309 pass through the limiting slide grooves 304 and extend to the outside of the placement rack 3 where a toggle plate 310 is fixedly installed. Because of the limiting protrusions 309, when the sliding block 306 slides inside the rectangular groove 303, the limiting protrusions 309 slide inside the limiting slide grooves 304, thereby limiting the moving range of the sliding block 306 and preventing the sliding block 306 from escaping from the rectangular groove 303.

[0028] A T-shaped slot 301 is provided on the side of the bottom of the placement rack 3 away from the rectangular slot 303, and an arc-shaped placement slot 302 is provided on the top of the placement rack 3. A flange 4 is provided on the top of the placement rack 3 located inside the arc-shaped placement slot 302, and the arc-shaped placement slot 302 is fitted with the flange 4. Because of the arc-shaped placement slot 302, after the flange 4 is correspondingly inserted into the arc-shaped placement slot 302, the flange 4 is tightly fitted with the arc-shaped placement slot 302, thereby improving the stability of the flange 4 when it is stuck in the arc-shaped placement slot 302.

[0029] The working principle of the utility model is:

[0030] The clamping plate 204 is pressed downward to slide the multiple groups of placement racks 3 into the bottom of the concave seat 1, so that the T-slot 301 at the bottom of the placement rack 3 is clamped on the surface of the corresponding T-block 104, and then the clamping plate 204 is released. Under the rebound action of the clamping spring 205, the clamping plate 204 is lifted up to clamp and fix the placement rack 3, and then the flange 4 is correspondingly clamped in the arc placement groove 302. After the flange 4 rolls over the top of the sliding block 306, under the rebound action of the reset spring 308, the sliding block 306 is lifted up and clamped on the surface of the flange 4, and at the same time, the connecting rod 102 is rotated to clamp the roller 103 on the surface of the flange 4, so that the flange 4 is clamped and fixed in the arc placement groove 302;

[0031] When taking the flange 4 from the arc-shaped placement groove 302, rotate the connecting rod 102 to make the roller 103 separate from the surface of the flange 4, and then push the toggle plate 310 downward to drive the sliding block 306 to slide down inside the rectangular groove 303 to separate from the surface of the flange 4, control the flange 4 to roll inside the arc-shaped placement groove 302, and make the flange 4 roll out from the arc-shaped placement groove 302.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0033] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
