Problems solved by technology

[0007] Ball cage type universal joint cage inner and outer spherical surface dimensions, inner and outer spherical surface center offset error and shape and position tolerance accuracy requirements are high, and the wall is thin and easy to deform during processing. It is difficult to guarantee its accuracy in general lathe processing. Clamping, it is more difficult to ensure the coaxiality error requirements of the inner and outer spherical surfaces, in order to meet the requirements of the complete vehicle matching and after-sales market for multiple varieties

Embodiment 1

[0037] Embodiment one: if figure 1 As shown, the flexible production line for universal joint cages according to the present invention includes each production unit for processing machine parts and a transmission system connected between each production unit, and the production unit includes a rough machining unit 1, a finishing unit Unit 2 and station unit 3, the rough machining unit 1 includes a rough grinding unit, and the rough grinding unit includes a double-turret CNC lathe arranged at the upstream of the transmission system. When grinding the upper and lower planes of the cage window, it is necessary to Guarantee the width of the 6 windows and the size of the centerline of the window to the reference plane B, locate the reference plane B, directly measure the width of the window and the height of the bottom surface of the window and the reference plane, so as to indirectly ensure the alignment of the centerline of the window to the reference plane B Dimensions. Therefor...

Embodiment 2

[0041]A processing method for processing a universal joint cage, comprising the following steps

[0042] The first step is to form the inner and outer spherical surfaces of the circular blank, and process the blank through the rough processing unit to form the inner and outer spherical surfaces;

[0043] The second step is positioning with the inner spherical surface and the reference plane B, using an automatic indexing device to punch 6 windows, and the reference plane B (the reference plane B can be reasonably determined by those skilled in the art as required);

[0044] The third step is carburizing and quenching, tempering and tempering to 58-62HRC, and quenching the stamped materials;

[0045] The fourth step is flat grinding rough and fine grinding datum plane B;

[0046] The fifth step is to position with reference plane B, grind 6 windows, and perform finishing machining;

[0047] The sixth step is to position the outer spherical surface and the reference plane B, g...

Abstract

The invention discloses a workpiece machining flexible production line and a machining method implemented through the same. The flexible production line comprises production units used for machining amachine part, and a conveying system connected between the production units; the production units include a rough machining unit, a finish machining unit and a station unit; and the roughing unit comprises a rough grinding unit. By adopting the technical scheme, according to the universal joint retainer flexible production line, three numerical control horizontal grinding machines and an automatic conveyor belt form a window, inner circle and outer circle grinding machining process control automatic line, complicated machining operation is achieved, the dimensional requirements, precision requirements and position requirements are effectively guaranteed, the part machining quality is stable, optimal fit clearances of produced universal joint retainers can be ensured, and impact, noise andvibration generated by universal joint assemblies during usage are reduced.

Description

technical field [0001] The invention relates to a flexible production line for workpiece processing, in particular to a flexible production line for workpiece processing and a processing method realized by using the same. Background technique [0002] Flexible production line is a complex and highly automated system, which organically combines technologies such as microelectronics, computer and system engineering, and ideally and satisfactorily resolves the contradiction between high automation and high flexibility in mechanical manufacturing. Since the birth of the first digitally controlled milling machine at the Massachusetts Institute of Technology in 1990s, flexible automation has entered the stage of practical production in the early 1990s. For decades, the application of a single CNC machine tool has gradually developed to machining centers, flexible manufacturing units, flexible production lines and computer integrated manufacturing systems, making flexible automatio...
