Abstract
The utility model relates to a boring fixture of a gearbox housing of a valve. The boring fixture comprises a circular disc, and four fixing claws capable of being connected with a main shaft of a machine tool are arranged on the back surface of the circular disc. The innovative points of the boring fixture lie in that a bracket of which the inner side surface is vertical to the circular disc is fixed on one side of the front surface of the circular disc; a circular truncated cone is arranged on the inner side surface of the bracket; a screw rod vertical to the circular truncated cone is arranged at the center of the circular truncated cone; a pressing block and a nut are sleeved on the screw rod; and a counter-balancing block is arranged on the other side of the front surface of the circular disc. The boring fixture has the advantages that when the boring fixture is used, the fixing claws on the back surface of the circular disc are connected and fixed with the main shaft of the machine tool, and one end surface of the gearbox housing clings to the circular truncated cone on the side surface of the bracket; the inner contour of the end surface is right jogged with the circular truncated cone; the screw rod passes through the other end of the gearbox housing and is then fixed on the bracket through the pressing block and the nut; and a corresponding counter-balancing block is replaced according to the weight of the side of the gearbox housing, and then the gearbox housing can be bored. The clamping is more convenient and more rapid while the boring precision is guaranteed.
Description
Technical field
The present invention relates to a kind of frock clamp, particularly a kind of valve gear tank shell boring jig.
Background technology
Valve is the device that makes the media flow in pipe arrangement and the equipment or stop, also controlling its flow, and the valve gear case plays the power-assisted effect when valve opening and closing.Like Fig. 1, shown in 2, when processing valve gear tank shell 10, need be at its sidepiece boring bevel pinion axis hole 9.Traditional processing method clamps for utilizing the two-jaw(ed)chuck that is connected with machine tool chief axis to cooperate with detent mechanism; It need be reequiped chuck according to the requirement of the centre of gyration, clamps inconvenience, and because gear box casing is bigger; Be prone to exist small rocking during rotation, the bore hole error is high.
Summary of the invention
The technical problem that the present invention will solve provides a kind of machining accuracy height, clamps valve gear tank shell boring jig easily.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of valve gear tank shell boring jig comprises disk; The back side of disk is provided with four fixed claws that can be connected with machine tool chief axis; Its innovative point is: the positive side of said disk is fixed with the medial surface support vertical with disk, and this support medial surface is provided with a round platform, and the round platform center is provided with a screw rod perpendicular to round platform; Be with briquetting and nut on the screw rod, also be provided with positioning screw on the support medial surface of round platform one side; The positive opposite side of said disk is provided with balancing weight.
The invention has the advantages that: during use; It is fixing that the fixed claw at the disk back side is connected with machine tool chief axis, and the end face of gear box casing is close to the round platform of cradle, and profile is just chimeric with round platform in the end face; Screw rod is fixed on the support through briquetting, nut after passing the other end of gear box casing; And by the location that positioning screw is realized gear box casing, can carry out bore hole processing, guaranteed to clamp on the bore hole precision convenient, quick.

The specific embodiment
Like Fig. 3, shown in 4, the present invention relates to a kind of machining accuracy height, clamp valve gear tank shell boring jig easily, comprise disk 1, fixed claw 2, support 3, round platform 4, screw rod 5, briquetting 6, balancing weight 7.
The back side of above-mentioned disk 1 is provided with four fixed claws 2, and this fixed claw 2 can be connected fixing with machine tool chief axis.A side is fixed with support 3 in the front of disk 1; The medial surface of this support 3 is vertical with disk 1; Which is provided with a round platform 4, the diameter of round platform 4 just is the internal diameter of valve gear tank shell end face flange face, is provided with a screw rod 5 perpendicular to round platform 4 at round platform 4 centers; Be useful on the valve gear tank shell is fixed on briquetting 6 and nut on the round platform 4 at cover on the screw rod 5; On support 3 medial surfaces of round platform 4 one sides, also be provided with locating support, locating support is provided with the positioning screw 8 of joining with its screw thread cunning, and opposite side is provided with balancing weight 7 in the front of disk 1.
During use; As shown in Figure 5, the fixed claw 2 at disk 1 back side is connected fixing with machine tool chief axis, the end face of gear box casing 8 is close to the round platform 4 of cradle; Profile is just chimeric with round platform 4 in the end face; Screw rod 5 is fixed on the support through briquetting 6, nut after passing the other end of gear box casing 8, and changes corresponding balancing weight according to this amount of stressing and can carry out bore hole processing, guaranteed to clamp on the bore hole precision convenient, quick.
