Abstract
The utility model relates to a fixture for processing a threaded hole of a backwater cover. The fixture comprises a chassis, a fixed disk, rotary pressing plates, locating pins, first fixed bolts and second fixed bolts, wherein four installing holes are formed in the fixed disk; at least two rotary pressing plates are symmetrically arranged on the fixed disk; the locating pins for being inserted into the installing holes are arranged under the rotary pressing plates; the first fixed blots for fixing the rotary pressing plates are arranged on the rotary pressing plate; the fixed disk is arranged on the chassis through the second fixed bolts; and when the backwater cover is arranged on the fixed disk, a center of the threaded hole of the backwater cover is concentric with a center of the chassis. According to the fixture for processing the threaded hole of the backwater cover, the secondary clamping is simple and convenient, the time for secondary clamping is shortened, and the processing efficiency is improved; and after secondary clamping, the center of a second threaded hole is concentric with the center of the chassis, so that the processing accuracy of the second threaded hole is ensured.
Description
Technical field
The utility model relates to a kind of anchor clamps, relates in particular to a kind of anchor clamps of the screwed hole that covers for backwater, belongs to the Workpiece clamping device technical field of machining.
Background technology
The structure of backwater lid is typically provided with the screwed hole of two symmetries as shown in Figure 1 on it, the backwater lid 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 backwater lid, use general anchor clamps that it is added man-hour, after a hole processing is finished, need carry out clamping again to the backwater lid, reduced working (machining) efficiency like this, and the machining accuracy of second screwed hole can not get ensureing.
The utility model content
The utility model purpose is that a kind of backwater lid hole processing anchor clamps that can improve working (machining) efficiency and guarantee machining accuracy are provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of backwater lid hole processing anchor clamps comprise chassis, fixed disk, rotary pressure plate, alignment pin, first set bolt and 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 first set bolt of rotary pressure plate; Described fixed disk is installed on the chassis by second set bolt; When the backwater lid was installed on the fixed disk, the screwed hole center of backwater lid was concentric with center chassis.
Preferably, to be provided with counterweight fast on described chassis.
Preferably, described second set bolt is arranged with two.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
Backwater lid hole processing anchor clamps of the present utility model, after first hole processing is finished, unclamp second set bolt, with behind the fixed disk Rotate 180 °, lock second set bolt, just can process second screwed hole, the 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 still with the centres on chassis, guaranteed the machining accuracy of second screwed hole.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the front view of backwater lid;
Accompanying drawing 2 is the front view of backwater lid hole processing anchor clamps of the present utility model;
Accompanying drawing 3 is the use state front view of bearing outer ring oilhole clamp for machining of the present utility model;
Wherein: 1, chassis; 2, fixed disk; 3, rotary pressure plate; 4, alignment pin; 5, first set bolt; 6, second set bolt; 7, installing hole; 8, backwater lid; 9, screwed hole; 10, balancing weight; 11, fixing hole.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Described in the utility model a kind of backwater lid hole processing anchor clamps as shown in Figure 2 comprise chassis 1, fixed disk 2, rotary pressure plate 3, alignment pin 4, first set bolt 5 and 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 backwater lid 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 first set bolt 5 of rotary pressure plate 3; Described fixed disk 2 is installed on the chassis 1 by two symmetrically arranged second set bolts 6; When backwater lid 8 is installed on the fixed disk 2, screwed hole 9 centers and chassis 1 centres of backwater lid 8; Also be provided with balancing weight 10 on the described chassis 1.
Described in the utility model a kind of backwater lid hole processing anchor clamps as shown in Figure 3, before the processing, at first backwater lid 8 to be processed is placed on the fixed disk 2, the fixing hole 11 of backwater lid 8 is aligned with installing hole 6, rotate rotary pressure plate 3 then, 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 first set bolt 4, play the effect that compresses backwater lid 8, then fixed disk 2 is installed on the chassis by second set bolt 6, so just can processes with regard to first screwed hole 9; After first screwed hole 9 machines, unclamp second set bolt 6, with behind fixed disk 2 Rotate 180s °, lock second set bolt 6, just can process second screwed hole 9.
Backwater lid hole processing anchor clamps of the present utility model, the 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 still 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.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
