In view of this, for the problems referred to above, propose a kind of reasonable in design and effectively improve the hydraulic pump cylinder body processing tool of above-mentioned disappearance.

Summary of the invention

The object of the present invention is to provide a kind of hydraulic pump cylinder body processing tool, adopt special gripping sleeve, can rely on the distortion of hydraulic cylinder inner sleeve that power is delivered on special gripping sleeve and clamp cylinder body, thereby make the cylindrical of cylinder body stressed evenly, avoid the clamping distortion of part.

In order to reach above-mentioned purpose, the invention provides a kind of hydraulic pump cylinder body processing tool, comprising: a clamp base, this clamp base rear end is connected with lathe; One hydraulic cylinder is connected on clamp base, and this hydraulic cylinder inwall is provided with the hydraulic cylinder inner sleeve; One is used for clamping the distortion gripping sleeve of cylinder body workpiece, coordinates to be installed in the hydraulic cylinder inner sleeve.

Described hydraulic cylinder all is equipped with locating flange in its end face both sides by screw, also by screw, mounting flange is installed on the hydraulic cylinder below locating flange.

Described distortion gripping sleeve is a cylinder, cut open many gaps that 1.5-2.5mm is wide along its circumferencial direction, and do not cut logical on distortion gripping sleeve length direction, the gap in twos that this is adjacent, wherein the length 5mm-10mm place from the other end is cut in gap, cut the other way around in another gap, is spaced from each other to be staggered state, and injects AB glue in the gap.

Described clamp base is fixed on lathe by alignment pin, and the hole axle fit clearance when wherein the alignment pin on clamp base is connected with Installing machine tool is at 0.5 μ m~1 μ m.

Described hydraulic cylinder is fastened on clamp base by hold-down screw.

The hole axle matching allowance of described hydraulic cylinder inner sleeve and hydraulic cylinder assembling uses freezing to assemble at 0.03mm~0.05mm, and the deflection of hydraulic cylinder inner sleeve is controlled at 0.03mm~0.07mm; Fit clearance between hydraulic cylinder inner sleeve and distortion gripping sleeve is at 0.3 μ m~0.5 μ m, and the gap between distortion gripping sleeve and workpiece is at 0.4 μ m~0.7 μ m.

Compared to existing apparatus, the invention enables workpiece on external peripheral surface stressed evenly, eliminated the workpiece deformation that causes because of clamping work pieces, also just fundamentally guaranteed the precision of institute's processing parts, the defective that this technological equipment has overcome the aspect existence of existing process technology has realized the self-control of hydraulic pressure vital part, has fundamentally guaranteed the precision of part, improve production efficiency, reduced production cost.

The specific embodiment

Relevant detailed description of the present invention and technology contents coordinate description of drawings as follows, yet accompanying drawing only provides the use of reference with explanation, and the present invention is limited.

Please refer to Fig. 1, a kind of hydraulic pump cylinder body processing tool comprises: a clamp base 9, and this clamp base rear end is connected with lathe; One hydraulic cylinder 7 is connected on clamp base, and this hydraulic cylinder inwall is provided with hydraulic cylinder inner sleeve 2; One is used for clamping the distortion gripping sleeve 3 of cylinder body workpiece, coordinates to be installed in the hydraulic cylinder inner sleeve.Described hydraulic cylinder all is equipped with locating flange 4 in its end face both sides by screw 5, also by screw 1, mounting flange 6 is installed on the hydraulic cylinder below locating flange.

With reference to Fig. 2 and shown in Figure 3, described distortion gripping sleeve is a cylinder, cut open many gaps that 1.5-2.5mm is wide along its circumferencial direction, and do not cut logical on distortion gripping sleeve length direction, the gap in twos that this is adjacent, wherein the length 5mm-10mm place from the other end is cut in gap, and cut the other way around in another gap, be spaced from each other and be staggered state, and inject AB glue in the gap.Described clamp base is fixed on lathe by alignment pin, and the hole axle fit clearance when wherein the alignment pin on clamp base 10 is connected with Installing machine tool is at 0.5 μ m~1 μ m.Described hydraulic cylinder is fastened on clamp base by hold-down screw 8.The hole axle matching allowance of described hydraulic cylinder inner sleeve and hydraulic cylinder assembling uses freezing to assemble at 0.03mm~0.05mm, and the deflection of hydraulic cylinder inner sleeve is controlled at 0.03mm~0.07mm; Fit clearance between hydraulic cylinder inner sleeve and distortion gripping sleeve is at 0.3 μ m~0.5 μ m, and the gap between distortion gripping sleeve and workpiece is at 0.4 μ m~0.7 μ m.Adopted technique scheme, make workpiece on external peripheral surface stressed evenly, eliminated the workpiece deformation that causes because of clamping work pieces, also just fundamentally guaranteed the precision of institute's processing parts, the defective that this technological equipment has overcome the aspect existence of existing process technology has realized the self-control of hydraulic pressure vital part, has fundamentally guaranteed the precision of part, improve production efficiency, reduced production cost.
