Abstract
The invention discloses a clamp for water return cover thread hole machining. The clamp comprises a base plate, a fixed plate, rotary pressing plates, positioning pins, first fixing bolts and second fixing bolts. Four mounting holes are reserved on the fixed plate. At least two rotary pressing plates are symmetrically disposed on the fixed plate. The positioning pins for inserting into the mounting holes are disposed below the rotary pressing plates. The first fixing bolts for fixing the rotary pressing plates are disposed on the rotary pressing plates. The fixed plate is mounted on the base plate through the second fixing bolts. When a water return cover is mounted on the fixed plate, a thread hole center of the water return cover is concentric with the center of the base plate. The clamp has the advantages that secondary clamp is simple and convenient, time for secondary clamp is shortened, machining efficiency is improved, the thread hole center of the water return cover is still concentric with the center of the base plate after secondary clamp, and machining precision of a second thread hole is guaranteed.
Description
Technical field
The present invention relates to a kind of anchor clamps, relate in particular to a kind of anchor clamps for the screwed hole on the water return cover, belong to the Workpiece clamping device technical field of machining.
Background technology
The structure of water return cover is typically provided with the screwed hole of two symmetries as shown in Figure 1 on it, water return cover belongs to the tired part of typical disk cover, often uses anchor clamps when its screwed hole of processing.Because screwed hole is not positioned at the center of water return cover, use general anchor clamps that it is added man-hour, after a hole processing is finished, need to carry out again clamping to water return cover, reduced like this working (machining) efficiency, and the machining accuracy of second screwed hole can not get ensureing.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of water return cover hole processing anchor clamps that can improve working (machining) efficiency and guarantee machining accuracy.
Technical solution of the present invention is achieved in that a kind of water return cover hole processing anchor clamps, comprises chassis, fixed disk, rotary pressure plate, alignment pin, the first set bolt and the second set bolt; Have four installing holes on the described fixed disk; Be arranged with at least two rotary pressure plates on the described fixed disk; Described rotary pressure plate below is provided with for the alignment pin that inserts installing hole; Described rotary pressure plate is provided with for fixing the first set bolt of rotary pressure plate; Described fixed disk is installed on the chassis by the second set bolt; When water return cover was installed on the fixed disk, the screwed hole center of water return cover was concentric with center chassis.
Preferably, to be provided with counterweight fast on described chassis.
Preferably, described the second set bolt is arranged with two.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
Water return cover hole processing anchor clamps of the present invention, after first hole processing is finished, unclamp the second set bolt, with behind the fixed disk Rotate 180 °, lock the second set bolt, just can process second screwed hole, secondary clamping is simple and convenient, has shortened the time of secondary clamping, improved working (machining) efficiency, and behind the secondary clamping, the center of second screwed hole or with the centres on chassis, guaranteed the machining accuracy of second screwed hole.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of water return cover hole processing anchor clamps as shown in Figure 2 comprise chassis 1, fixed disk 2, rotary pressure plate 3, alignment pin 4, the first set bolt 5 and the second set bolt 6; Have four installing holes 7 on the described fixed disk 2; Described installing hole 7 is identical with fixing hole 11 sizes of water return cover 8; Be arranged with at least two rotary pressure plates 3 on the described fixed disk 2; Described rotary pressure plate 3 belows are provided with for the alignment pin 4 that inserts installing hole 7; Described rotary pressure plate 3 is provided with for fixing the first set bolt 5 of rotary pressure plate 3; Described fixed disk 2 is installed on the chassis 1 by two symmetrically arranged the second set bolts 6; When water return cover 8 is installed on the fixed disk 2, screwed hole 9 centers of water return cover 8 and chassis 1 centres; Also be provided with balancing weight 10 on the described chassis 1.
Of the present invention a kind of water return cover hole processing anchor clamps as shown in Figure 3, before the processing, at first water return cover to be processed 8 is placed on the fixed disk 2, the fixing hole 11 of water return cover 8 is aligned with installing hole 6, then rotate rotary pressure plate 3, the alignment pin of rotary pressure plate 3 belows is inserted in fixing hole 11 and the installing hole 7, fix rotary pressure plate 3 with the first set bolt 4, play the effect that compresses water return cover 8, then fixed disk 2 is installed on the chassis by the second set bolt 6, so just can processes with regard to first screwed hole 9; After first screwed hole 9 machines, unclamp the second set bolt 6, with behind fixed disk 2 Rotate 180s °, lock the second set bolt 6, just can process second screwed hole 9.
Water return cover hole processing anchor clamps of the present invention, secondary clamping is simple and convenient, has shortened the time of secondary clamping, improved working (machining) efficiency, and behind the secondary clamping, the center of second screwed hole or with the centres on chassis, guaranteed the machining accuracy of second screwed hole; Balancing weight can guarantee the anchor clamps stability in when rotation, has further guaranteed the machining accuracy of screwed hole.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
