Problems solved by technology

Due to the large diameter of the cylinder bore of the diesel engine frame and the large allowance of the casting blank, the cutting resistance of the traditional boring tool due to the insufficient rigidity of the boring bar will cause the boring tool to jump, resulting in the out-of-round cylinder hole after boring. If the size tolerance and shape tolerance of the cylinder bore are out of tolerance, it will affect the assembly accuracy of the cylinder liner, thereby affecting the movement of the piston in the cylinder liner, affecting the normal operation of the diesel engine, and even causing serious consequences of cylinder scuffing in the diesel engine

Embodiment Construction

[0020] The present invention will be further described below in conjunction with drawings and embodiments.

[0021] Such as figure 1 As shown, the present invention includes a boring bar transmission mechanism 2, a cutter body mechanism 3, and a boring bar mechanism 4. The boring bar transmission mechanism 2 is arranged on one end of a boring bar 43, and includes a worm wheel 21, a worm screw 22, a worm gear box 23, and a pair of supports Bearing 24, positioning frame 25, positioning seat 26. The worm wheel 21 of this embodiment is formed by fixedly connecting the wheel rim 211 and the wheel core 212. The wheel core 212 and the end of the boring bar 43 are fixedly connected by a flat key. 28. On the small retaining ring 27, the large retaining ring 28 and the small retaining ring 27 are respectively installed in the step holes on both sides of the worm gear casing 23, and the worm gear casing cover 29 is fastened on the outer end of the worm gear casing 23 by screws. The wor...

Abstract

The invention discloses a diesel engine frame air cylinder hole boring device, which comprises a boring rod transmission mechanism, a boring rod mechanism and a cutter body mechanism, wherein the boring rod transmission mechanism is arranged on one end of a boring rod and comprises a worm gear, a worm, a worm gear box body, a pair of supporting bearings, a positioning frame and a positioning seat. The worm gear is fixedly connected with the end of the boring rod, two sides of the worm gear are supported inside one end of the worm gear box body through the pair of supporting bearings and a retainer ring, and the worm is arranged on one side of the worm gear. One end of the boring rod is supported inside the other end of the worm gear box body through a slide bearing, the other end of the boring rod is supported on a machine tool worktable through a conical roller bearing and the positioning seat, the cutter body mechanism can move along the axial direction of the boring rod, and a lead screw transmission mechanism and a cutter body position measurement mechanism are also arranged inside the boring rod. Due to the adoption of the diesel engine frame air cylinder hole boring device, the cutter body mechanism can automatically and stably move a cutter on the boring rod at a constant speed so as to boring an air cylinder hole, so that the diesel engine frame air cylinder hole after being machined in one step can meet the size tolerance and verticality tolerance requirements, and the depth of the bored hole also can be measured.

Description

technical field [0001] The invention relates to a boring device, in particular to a boring device for a diesel engine frame capable of measuring the depth of the boring, and belongs to the technical field of metal cutting. Background technique [0002] The diesel engine frame is the core component of the diesel engine. The cylinder liner is installed in the cylinder bore of the diesel engine frame, and the piston is installed in the cylinder liner. The machining tolerance and position tolerance of the cylinder bore are very demanding. Due to the large diameter of the cylinder bore of the diesel engine frame and the large allowance of the casting blank, the cutting resistance of the traditional boring tool due to the insufficient rigidity of the boring bar will cause the boring tool to jump, resulting in the out-of-round cylinder hole after boring. If the size tolerance and shape tolerance of the cylinder bore are out of tolerance, it will affect the assembly accuracy of the...
