Abstract
A centering fixture for boring comprises a hydraulic mechanism which comprises an oil cylinder, a piston and oil tubes, a transitional disk is arranged on the oil cylinder, and an upper clamping sleeve and a centering ring are arranged on the transitional disk; a positioning block and a cushion block are fixed on the upper clamping sleeve by a bolt; one end of a pull rod is fixedly connected with the piston, and the axial section of the other end of the pull rod is shaped like a T; and a hold-down block is arranged between the pull rod and a workpiece. The upper clamping sleeve and the centering ring can be of an integrated structure. The section of the hold-down block is shaped like a U, and the size of the opening of the hold-down block is matched with the diameter of the pull rod. The centering fixture has the beneficial effects that: since the structure with the upper clamping sleeve and the centering ring and the positioning block are adopted, the workpiece cannot shift radially and circumferentially, the structure is reasonable, and moreover, the centering fixture is convenient to operate.
Description
Technical field
The present invention relates to the anchor clamps field, especially relate to a kind of boring centralizer.
Background technology
The present centralizer that adopts has the anchor clamps of location structure, complex structure and poor operability; The anchor clamps that do not have location structure, although simple in structure, result of use is poor.
Summary of the invention
The object of the present invention is to provide boring centralizer a kind of rational in infrastructure, easy to operate.
Boring centralizer comprises a hydraulic means that is made of oil cylinder, piston and oil pipe, and oil cylinder is provided with transition disc, and transition disc is provided with to clamp goes up cover and fixed core ring; Locating piece and cushion block put by being bolted in the clamping; One end of pull bar is fixedlyed connected with piston, and the axial cross section of the other end is the T font; Be provided with briquetting between pull bar and the workpiece.Cover and fixed core ring can be made into integrative-structure in the described clamping.Described briquetting cross section takes the shape of the letter U, and openings of sizes matches with the diameter of pull bar.
The effect that the present invention is useful is: go up cover and fixed core ring structure owing to adopted to clamp, and locating piece, guaranteed that therefore workpiece does not produce radially and circumferentially moves, rational in infrastructure and easy to operate.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present invention;
The specific embodiment:
As shown in Figure 1, this boring centralizer comprises a hydraulic means that is made of oil cylinder 9, piston 11 and oil pipe 10, and oil cylinder 9 is provided with transition disc 8, and transition disc 8 is provided with to clamp goes up cover 7 and fixed core ring 12; Locating piece 5 and cushion block 6 are fixed on to clamp by bolt 4 and go up on the cover 7; One end of pull bar 1 is screw thread with piston 11 fixedlys connected, and the axial cross section of the other end is the T font; Be provided with briquetting 2 between pull bar 1 and the workpiece 3.Described briquetting 2 cross sections take the shape of the letter U, and openings of sizes matches with the diameter of pull bar 1.The course of work: workpiece to be processed 3 is positioned over to clamp and goes up on the cover 7, fixed core ring 12 places to clamp and goes up on the cover 7, guarantees that workpiece to be processed 3 does not produce radial displacement, and locating piece 5 guarantees the circumferential location of workpiece 3, by oil cylinder 9 pulling pull bars 1, reach the purpose that compresses workpiece to be processed 3.Workpiece to be processed 3 has been located and has been finished like this, just can hole and process.
