Description

Technical Field

[0001] This utility model belongs to the field of tooling for mechanical processing equipment, and specifically relates to a dual-station irregular-shaped deceleration pump casing drilling and milling integrated fixture. Background Technology

[0002] Gear reducers are a crucial component in automobiles. With the rapid development of the automotive industry, the demand for gear reducers has increased significantly. However, the pump housing of a gear reducer has a unique shape, requiring numerous and complex machining processes. Previously, machining gear reducer housings involved manual clamping, with one fixture per process. A single production line required three machining centers and two operators, necessitating multiple workpiece clamping operations. This excessive use of machine tools and operators resulted in high processing costs and low production efficiency, especially in mass production where extremely high precision was required, making it difficult to guarantee quality. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a dual-station irregular-shaped deceleration pump casing drilling and milling integrated fixture with simple and compact structure, high degree of automation, and guaranteed quality.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: a dual-station irregular-shaped deceleration pump housing drilling and milling integrated fixture includes a base plate, an oil passage block, a front upright plate, a rear upright plate, stiffening plates, and lifting rings. Its features are: a front upright plate is fixed to the front part above the base plate; a rear upright plate is fixed to the rear edge of the base plate, the rear upright plate is higher than the front upright plate, and its length is equal to that of the front upright plate; two parallel stiffening plates are used for fixed support between the front and rear upright plates; a first-stage station is set on the right side in front of the front upright plate; a second-stage station is set in the middle of the front of the front upright plate; a second-stage station is set on the left side in front of the front upright plate; a reference hole is set at the center of the upper surface of the front upright plate; a second-stage station is set in front of the rear upright plate corresponding to the second-stage station; a third-stage station is set in front of the rear upright plate corresponding to the first-stage station; and a third-stage station is set in front of the rear upright plate corresponding to the first-stage station. The front of the upright plate corresponds to the first workstation of the first process and the second workstation of the third process. A support sleeve is fixedly installed on the upright plate at the center of each workstation. A limit pin is installed on the upright plate around the support sleeve. A centering flange shaft is installed at the center of the support sleeve. Two hydraulic angle cylinders are fixedly installed on the upright plate around the support sleeve. An angle cylinder pressure plate is installed at the center of the hydraulic angle cylinder. Three anti-misalignment guide rods are fixedly installed at 120 degrees on the front and rear upright plates around each support sleeve. The anti-misalignment guide rods at the second workstation of the first process are fixedly installed on the front upright plate below. A hydraulic support cylinder is installed above the hydraulic support cylinder seat. An oil passage block is fixed at the middle edge of the right side of the bottom plate. Oil port one, oil port two, and oil port three are provided on the oil passage block. Four lifting rings are fixed above the left and right ends of the front and rear upright plates.

[0005] The beneficial effects of this utility model are: the dual-station irregular-shaped reducer pump housing drilling and milling integrated fixture adopts a hydraulic system to control automatic clamping for drilling and milling operations, saving manpower and material resources and improving production efficiency. It changes the process from one fixture per process to one fixture for multiple processes, reducing the number of machine tool setups and clamping operations, and minimizing workpiece impacts caused by multiple clamping operations that affect the workpiece's processing quality.
