Detailed Description

The utility model is further described below with reference to the accompanying drawings.

The utility model relates to a radiator pipe plate processing clamp which consists of a foot cup 1, a supporting seat and a baffle plate 4, and is shown in fig. 1 and 2. The supporting seat structure is shown in fig. 3, and mainly comprises a bottom plate 2 and brackets 3 arranged on two sides of the bottom plate 2, wherein foot cup 1 mounting holes are formed in four corners of the bottom plate 2 and used for mounting foot cups, the foot cups are standard components and provided with adjusting nuts, the height of each foot cup is supported by screwing through threads, and the 4 foot cups 1 are matched for use. The level of the base is adjusted by adjusting the adjusting nut on the foot cup.

As shown in fig. 3, baffle shaft mounting holes 31,2 are arranged in the middle of two brackets 3, the baffle shaft mounting holes 31 are coaxial, and the brackets 3 are symmetrical with the center of the bottom plate. The baffle 4 mainly comprises a positioning plate 43, an intermediate shaft 41 and a handle 42, as shown in fig. 4. The baffle shaft mounting hole 31 on the bracket 3 is matched with the bearing 32 and the retainer ring and is used for mounting the intermediate shaft 41 for fixing the baffle 4; the two opposite directions of the two brackets 3 are taken as the inner direction and the opposite direction, so that the positioning plates 43 are arranged on the inner side of the brackets 3, the handles 42 are arranged on the outer side of the brackets 3, two ends of the radiator 6 are arranged on the two positioning plates 43 in a working room, the handles 42 on the outer side of the brackets are rotated, and the tube plate is rotated to a proper position for processing.

The locating plates 43 are provided with tube plate locating grooves which are U-shaped and used for locating the end parts of the radiators, and the opening directions of the U-shaped grooves of the two locating plates 43 are consistent. The handle 42 is provided with a pin hole, a pin 421 is arranged in the pin hole, the outer side of the bracket 3 surrounds the baffle shaft mounting hole 31, three pin holes are arranged, and the pin 421 on the baffle handle 42 can be inserted into the pin holes for positioning the 3 working positions of the baffle 4.
