Tooling mechanism for making holes in oil pump housing of hand pallet truck

Abstract

The invention relates to a tooling mechanism for making holes in the oil pump housing of a hand pallet truck. The tooling mechanism comprises a clamp for clamping the oil pump housing to-be-machined, and is characterized in that the clamp comprises a flange plate for fixing the oil pump housing to-be-machined; the flange plate is arranged on a chuck of a numerically controlled index plate; the integral center of gyration of the clamp is consistent with the center of gyration of the numerically controlled index plate; the numerically controlled index plate is connected with a workbench of a machining center through a positioning key in a centered manner, and is fixed on the workbench through a pressure plate and pressure plate bolts; an oil pipe on the numerically controlled index plate is communicated with an external hydraulic station; the control wire of the numerically controlled index plate is connected with a machine tool control system through a signal wire and a magnifier. According to the invention, the numerically controlled index plate is combined with the flange plate and corresponding mechanisms, the machined part of a workpiece serves as positioning reference, and the machine tool control system is used for controlling, so that all holes in different planes can be made in one step on a machining center machine tool; the processing processes of the oil pump housing are reduced; the occupied area is saved; the production efficiency and the processing quality are improved; the number of workers and the labor intensity are reduced.

Description

technical field [0001] The invention relates to a fixture of a machine tool, in particular to a tooling mechanism for machining the hole of an oil pump shell of a manual pallet truck. Background technique [0002] The oil pump housing is the core part of the manual pallet truck. Its function is similar to the valve seat of the hydraulic jack. The oil pump housing is equipped with functional parts such as the plunger pump, plunger cylinder, working valve, and control valve. It also serves as a mechanical connection. and supporting functions. The structure is relatively complicated, especially the various holes distributed on the body, including holes of different sizes, holes of different depths, holes of multi-step steps, holes of various threads, holes for technology and so on. In the prior art, the processing of these holes all stays in the single-process working state on ordinary machine tools, that is, clamping once and processing once. When there are many holes in the ...

Problems solved by technology

In the prior art, the processing of these holes all stays in the single-process working state on ordinary machine tools, that is, clamping once and processing once. When there are many holes in the oil pump shell, multiple clamping, multiple disassembly, and multiple processing are required. The processing cycle of the entire part is long, the number of fixtures is large, and the processing quality is not stable. In particular, the position accuracy between each hole system is not easy to guarantee, the processing efficiency is low, and the energy consumption and labor intensity of operators are also high.
