Description

Technical Field

[0001] This utility model relates to the technical field of machining, and more specifically, to a reference transfer tooling and platform for machining cylindrical irregular parts. Background Technology

[0002] For clamping cylindrical irregular-shaped parts, the welded structural component runs through the middle section, and the round flanges at both ends have inconsistent dimensions, making rapid positioning difficult during machining. When using a V-shaped tooling platform for positioning, the different dimensions of the round flanges at both ends lead to large clamping errors, requiring adjustments to the position of each part, significantly reducing machining efficiency. Utility Model Content

[0003] The main purpose of this invention is to provide a reference transfer tooling and platform for processing cylindrical irregular parts, so as to solve the technical problem of low processing efficiency in the prior art.

[0004] To achieve the above objectives, according to the first aspect of this utility model, a reference transfer tooling for machining cylindrical irregular-shaped parts is provided, the technical solution of which is as follows:

[0005] A reference transfer fixture for machining cylindrical irregular parts, wherein the cylindrical irregular parts have a first circular flange and a second circular flange at both ends, the outer diameter of the first circular flange being smaller than the outer diameter of the second circular flange. The reference transfer fixture includes: a sleeve, the sleeve having a circular groove inside for inserting the first circular flange, and a support section outside the sleeve that is adapted to the outer diameter of the second circular flange; and a fixing structure for detachably connecting the first circular flange and the sleeve.

[0006] The reference transfer fixture of this invention can transfer one of the reference surfaces (first circular flange) of the cylindrical irregular part to a support section that is compatible with the second circular flange. The reference transfer fixture and the first circular flange can be quickly disassembled and assembled, so it can be quickly positioned and clamped, significantly improving the processing efficiency.

[0007] As a further improvement to the aforementioned reference transfer tooling for machining cylindrical irregular parts: the fixing structure includes a first fixing mechanism, which includes a through hole and a pin. The through hole is arranged radially along the sleeve and matches the flange hole of the first circular flange. The pin passes through the through hole and the flange hole in sequence. Thus, the flange hole of the first circular flange itself is fully utilized, resulting in a simple structure and convenient assembly and disassembly.

[0008] As a further improvement to the aforementioned reference transfer tooling for machining cylindrical irregular parts: the through hole size is larger than the flange hole size, and the pin has a larger diameter section adapted to the through hole and a smaller diameter section adapted to the flange hole. This significantly improves the fixing effect.

[0009] As a further improvement to the aforementioned reference transfer fixture for processing cylindrical irregular parts: the first fixing mechanism consists of two symmetrically distributed parts. This significantly improves the fixing effect.

[0010] As a further improvement to the aforementioned reference transfer tooling for machining cylindrical irregular parts, the sleeve also has a platform stage on its exterior. The outer diameter of the platform stage is larger than the outer diameter of the support section, and the circular groove is located inside the platform stage. This allows the support section to be quickly installed onto the corresponding platform positioning part, improving positioning and clamping efficiency.

[0011] As a further improvement to the aforementioned reference transfer tooling for machining cylindrical irregular parts: the fixing structure includes a second fixing mechanism, which comprises an arc-shaped plate, an axial screw, and a threaded groove. The arc-shaped plate has an axial threaded hole, and the threaded groove is located at the end of the stage. The axial screw passes through the axial threaded hole and the threaded groove in sequence. Therefore, the fixing effect is good in terms of assembly and disassembly.

[0012] As a further improvement to the aforementioned reference transfer fixture for processing cylindrical irregular parts: the second fixing mechanism consists of at least two symmetrically distributed members; the inner edge of the arc-shaped plate extends 2-5 mm beyond the inner edge of the stage. This significantly improves the fixing effect.

[0013] As a further improvement to the aforementioned reference transfer tooling for machining cylindrical irregular parts, each second fixing mechanism includes at least two sets of threaded holes, threaded grooves, and screws. This significantly improves the fixing effect.

[0014] As a further improvement to the aforementioned reference transfer tooling for machining cylindrical irregular parts: the fixing structure includes a third fixing mechanism, which comprises a radial threaded hole and a radial screw. The radial threaded hole penetrates the stage tube wall, and the radial screw passes through the radial threaded hole and abuts against the outside of the first circular flange. This significantly improves the fixing effect.

[0015] To achieve the above objectives, according to a second aspect of this utility model, a platform for processing cylindrical irregular-shaped parts is provided, the technical solution of which is as follows:

[0016] A platform for processing cylindrical irregular parts, wherein the cylindrical irregular parts have a first round flange and a second round flange at both ends, the outer diameter of the first round flange being smaller than the outer diameter of the second round flange, the platform includes two V-block positioning parts distributed at both ends of the cylindrical irregular parts, and the platform also includes the reference transfer tooling described in the first aspect above, wherein one V-block positioning part cooperates with the support section of the reference transfer tooling, and the other V-block positioning part cooperates with the second round flange.

[0017] In summary, the reference transfer fixture of this utility model has a simple structure and is easy to assemble and disassemble with the first round flange. It can transfer the reference of the first round flange to the same position as the second round flange at the other end, which shortens a lot of auxiliary time and significantly improves processing quality and efficiency, especially improving appearance quality and increasing the pass rate of machining.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Additional aspects and advantages of the present invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the present invention.
