Description

Technical Field

[0001] This utility model relates to the field of honing technology, and in particular to a multifunctional honing device. Background Technology

[0002] In the shipbuilding industry, high standards are required for the dimensional accuracy, roundness, cylindricity, coaxiality, and surface roughness of the stern tube inner bore. Currently, the machining of stern tube inner bores in factories, such as... Figure 1 As shown, clamp one end of the front stern tube seat, and use the sternstock to support the rear stern tube seat, connecting the intermediate pipe, front stern tube seat, and rear stern tube seat to adjust the workpiece's outer diameter. Machining center rest positions ① and ② at both ends, removing the sternstock, and supporting center rest position ① to machine the flange end A and the inner hole, leaving a 2mm allowance on one side of the inner hole; any defects should be repaired promptly. After rough machining, perform finish machining after the stern tube has cooled. During finish machining, pay attention to the length and diameter of the steps in the inner hole, and then polish it. Turn the stern tube around, use a copper pad to clamp one end of the flange, support center rest position ②, and machine the dimension at point B, following the same process as above. Currently, lathe machining cannot effectively address the requirements for roundness, cylindricity, coaxiality, and surface roughness of the inner hole, easily resulting in elliptical inner holes. To solve these problems, and considering the development trend of modern shipbuilding, a multi-functional honing device is needed to ensure the machining quality of the stern tube inner hole. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned technical problems and provide a multifunctional honing device to ensure the dimensional accuracy, roundness, cylindricity, coaxiality and roughness requirements of the stern tube inner hole.

[0004] To achieve the above technical objectives and meet the above technical requirements, the technical solution adopted by this utility model is: a multifunctional honing device, including a support frame, the support frame being set on a machine tool track, two thick-walled tubes being provided on the support frames, clamping sleeves being provided on the thick-walled tubes, and honing heads being provided at the ends of the thick-walled tubes. The support frame includes a lower base, an upper base, and a flat key, an upper cover being provided on the upper base, and copper bushings being provided inside the upper base and the upper cover.

[0005] Preferably, the copper bushing has a two-part structure, which is fixed to the upper cover and the upper base respectively by screws.

[0006] Preferably, the outer diameter of the copper bushing is interference-fitted with the inner hole of the upper cover and the upper base.

[0007] Preferably, the inner hole of the copper bushing is provided with axial and longitudinal oil grooves.

[0008] Compared with the traditional structure, the utility model has the advantages of reasonable structure design, convenient, safe, efficient, solves the size precision, roundness, cylindricity, coaxiality and roughness problem of the stern tube inner hole, improves the processing quality of the stern tube inner hole.

[0014] The utility model is further explained below.

[0015] Refer to the accompanying Figures 2-4 A kind of multifunctional honing device, including support frame 2, the support frame 2 is arranged on machine tool track, two the thick-walled tube 4 is provided on the support frame 2, the clamping sleeve 3 is provided on the thick-walled tube 4, the thick-walled tube 4 end is provided with honing head 1, the support frame 2 includes lower base 21, upper base 22, flat key 25, the upper base 22 is provided with upper cover 23, the upper base 22, upper cover 23 are provided with copper bushing 24 in.

[0016] In the preferred embodiment, the copper bushing 24 outer diameter and upper cover 23, upper base 22 inner hole interference fit, and the interference amount is 0.01~0.02mm.

[0017] In the preferred embodiment, the copper bushing 24 is two half formula structure, is fixed on upper cover 23 and upper base 22 respectively by screw.

[0018] In the preferred embodiment, the copper bushing 24 inner hole is provided with axial and longitudinal oil groove.

[0019] In the embodiment, the thick-walled pipe 4 is connected with the machine tool through the clamping sleeve 3, is supported by the two support frames 2 distributed on the machine tool track, the honing head 1 is provided with a fine grinding wheel, the inner hole of the stern tube is honed, and low-speed grinding is performed in the rotation and reciprocating motion of the honing head 2 and the workpiece. In order to reduce the influence of the non-coaxiality of the machine tool spindle and the stern tube center and the rotation of the machine tool spindle on the machining precision, the honing head 1 and the machine tool spindle are connected in a floating mode, and the inner hole of the stern tube is used as a guide. In the honing process, the fine grinding wheel and the overlapping contact points of the hole wall interfere with and modify each other, so that the surface quality and the precision requirement of the hole wall are continuously improved.
