Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the embodiments.

As shown in fig. 1 and 2, an embodiment of the utility model provides a multi-group processing tool special for boring, which comprises a support plate 1, wherein two groups of symmetrically distributed clamping arms for clamping a circular tube are arranged on the support plate 1, the distance between the clamping plates 2 of the two groups of clamping arms and the horizontal axis of the support plate 1 is equal, each clamping arm comprises a clamping plate 2, a plurality of connecting rods 3 are fixedly connected to the clamping plates 2, the plurality of connecting rods 3 are arranged in parallel, a limiting piece 4 is respectively and fixedly connected to each connecting rod 3, specifically, the horizontal cross section of each limiting piece 4 is semicircular, in the embodiment, four connecting rods 3 are arranged on each clamping plate 2, and the limiting pieces 4 of the two groups of clamping arms are spliced into a limiting ring for fixing the limiting circular tube when being contacted. The spray heads 5 used for flushing the boring waste chips are fixedly connected to the clamping plate 2, specifically, the number of the spray heads 5 in the embodiment is eight, the spray heads are symmetrically distributed on two sides of the four limiting rings, and every two of the spray heads are in a group and respectively face to an area defined by the limiting rings. Specifically, the water outlet pipe of the water pump is communicated with eight branch pipes 12, and each branch pipe 12 is respectively connected with one spray head 5.

Still fixedly connected with is used for the cylinder 6 that the synchronous drive splint 2 removed on support plate 1, and the quantity of cylinder 6 is four in this embodiment, and four cylinders 6 are two liang a set of splint 2 removal of driving respectively, and four cylinders 6 carry out on-off control through same power to it is the same to guarantee that two sets of cylinders 6 drive the distance that splint 2 removed. The both sides of splint 2 are provided with baffle 7 that is used for preventing the sweeps from spattering outward, the bottom and the 1 top fixed connection of support plate of baffle 7, the height of splint 2 is highly parallel and level with baffle 7 mutually, smooth track (not shown in the figure) has been seted up on baffle 7, splint 2 and baffle 7 sliding connection.
