Referring to fig. 1, an auxiliary table of a bench drill for chamfering a flange plate includes a circular rotary plate 200. The rotary disc 200 is attached to the side surface of the workbench 100 far from the ground, and is rotatably connected with the workbench 100 through a rotary bearing. Three supporting blocks 300 are arranged on the rotating disc 200, and one ends of the three supporting blocks 300 close to the circle center of the rotating disc 200 are hinged with the rotating disc 200.

Referring to fig. 2, in order to prevent the flange from slipping when a user rotates the rotary plate 200, an auxiliary fixing assembly 400 is provided on the rotary plate 200. The auxiliary fixing assembly 400 comprises two supporting rods 440, a driving gear 410 coaxially and rotatably connected with the rotating disc 200, a driving rod 420 coaxially welded with the driving gear 410, and a supporting frame 430 welded with the rotating disc 200, wherein the driving gear 410 is a bevel gear, teeth 442 meshed with the driving gear 410 are formed on the supporting rods 440, and the toothed side surfaces of the supporting rods 440 face the rotating disc 200, so that scraps generated by flange plate processing are not easily adhered to the teeth 442 of the supporting rods 440. The lateral wall of the supporting rod 440 is provided with a sliding groove 441 parallel to the radial direction of the rotating disc 200, the sliding groove 441 is a T-shaped sliding groove, the supporting frame 430 comprises a limiting block, one end of the limiting block is welded with the rotating disc 200, and the other end of the limiting block is matched with the sliding groove 441 in shape and is connected with the sliding groove 441 in a sliding manner.

Referring to fig. 2 and 3, the two support rods 440 are each provided with a clamping groove 443 on one side abutted against the side wall of the flange, the rotating disc 200 is provided with two positioning plates 500, one positioning plate 500 is arranged corresponding to one support rod 440, the positioning plate 500 is integrally formed with a clamping block 510 in interference fit with the clamping groove 443, and a side surface of the positioning plate 500 is attached to the table surface of the rotating disc 200 to provide partial supporting force for the support rods 440, so that the support rods 440 are not easily separated from the drive gear 410. In order to make locating plate 500 be difficult for scratch ring flange inner wall when the butt joint with the ring flange, be stained with the flexible layer on locating plate 500, the flexible layer generally adopts butadiene-acrylonitrile rubber.

Referring to fig. 2 and 4, in order to prevent the support rod 440 from moving away from the inner wall of the flange after the positioning plate 500 abuts against the flange, a locking assembly for locking the sliding distance between the support rod 440 and the support frame 430 is disposed on the rotating plate 200. The locking assembly comprises a baffle 600 rotatably connected with the rotating disc 200 through a rotating shaft, and an elastic body 700 for connecting the baffle 600 with the rotating disc 200, wherein the elastic body 700 is preferably a torsion spring, one end of the torsion spring is welded with the baffle 600, and the other end of the torsion spring is abutted to the rotating disc 200. Under the action of the elasticity of the torsion spring, the baffle 600 and the rotary disc 200 are obliquely arranged, and one end of the baffle 600 far away from the rotary disc 200 is attached to the teeth 442 of the support rod 440. The drive gear 410 is rotated to enable the supporting rod 440 to move towards the direction close to the inner wall of the flange plate, the elastic body 700 is compressed, after the supporting rod 440 is abutted to the inner wall of the flange plate, under the effect that the elastic body 700 recovers deformation force, the baffle 440 is abutted to the teeth 442 of the supporting rod 440, and due to the limiting effect of the limiting block on the supporting rod 440, the supporting rod 440 cannot move towards the direction far away from the flange plate, so that the operation reliability of the auxiliary fixing assembly 400 is improved.

In order to prevent the scraps generated during the processing from easily entering the engagement portion between the driving gear 410 and the supporting rod 440, the housing 800 is welded to the rotating disc 200, the housing 800 covers the driving gear 410, one end of the driving rod 420 is welded to the driving gear 410, and the other end of the driving rod passes through the housing 800 to be held by a user.

The implementation principle of the embodiment is as follows: the flange plate is placed on the supporting block 300, the flange plate is sleeved on the outer side of the supporting rod 440, the driving rod 420 is rotated to enable the driving gear 410 to rotate to drive the supporting rod 440 to move towards the direction close to the inner wall of the flange plate, the elastic body 700 is compressed, the baffle plate 600 rotates, and the positioning plate 500 is abutted to the inner wall of the flange plate, so that the positioning of the flange plate is realized. When the user loosens the driving rod 420, under the restoring force of the elastic body 700, the baffle 600 abuts against the teeth 442 of the supporting rod 440, so that the supporting rod 440 cannot move in the direction away from the inner wall of the flange, thereby improving the stability of the flange fixation.

When the flange plate is dismounted, the baffle 600 is rotated to release the abutting state of one side of the baffle 600 far away from the rotating disc 200 and the teeth 440 of the supporting rod 440, and the driving rod 420 is rotated to rotate the driving gear 410 to drive the supporting rod 440 to release the abutting state with the inner wall of the flange plate, so that a user can conveniently take down the flange plate.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
