Pump workpiece eccentricity circle machining tooling and use method thereof

Abstract

The invention discloses pump workpiece eccentricity circle machining tooling and a user method thereof. The pump workpiece eccentricity circle machining tooling comprises a tooling base, a connecting plate, a three-jaw chuck and a positioning-shaft eccentricity adjustment device which is arranged on the connecting plate, a positioning shaft is arranged on one side of the tooling base, away from the connecting plate, a movable sliding plate capable of shielding a through hole arranged in the three-jaw chuck is arranged at the lower inner portion of the three-jaw chuck, the positioning shaft penetrates the through hole arranged in the movable sliding plate to enable the connecting plate to be fixedly connected with the three-jaw chuck with a round nut, and the eccentric distance between the axis of the positioning shaft and the extension line of the axis of the connecting plate is 5-6mm; three-jaw chuck positioning devices are further arranged on two corresponding surfaces of the three-jaw chuck and the connecting plate. By the arrangement, one-step clamping of a pump workpiece is realized, machining of one eccentric outer circle and one eccentric hollow inner circle of the pump workpiece is achieved, machining efficiency and machining precision of the pump workpiece are further improved, utilization rate of digital-controlled lathe equipment is increased, and machining cost of the pump workpiece is lowered.

Description

Technical field [0001] The invention belongs to a tooling for a lathe and a use method thereof, in particular to a tooling for processing the eccentric circle of a water pump workpiece for a lathe and a use method thereof. Background technique [0002] A workpiece of the water pump needs to be processed into an eccentric outer circle and an eccentric hollow inner circle. At present, an eccentric outer circle and an eccentric hollow inner circle that need to be processed for the water pump workpiece are usually realized by two clamping operations, each of which is installed. To realize the machining of an eccentric circle, the disadvantages of the two loading processes are obvious. The first is to reduce the work efficiency. The two loadings waste the time of loading and unloading the workpiece, which reduces the effective utilization of the CNC lathe equipment. It is due to multiple loading and unloading of the workpiece, resulting in cumulative errors in the processing process, ...

[0002] A water pump workpiece needs to be machined with an eccentric outer circle and an eccentric hollow inner circle. At present, an eccentric outer circle and an eccentric hollow inner circle that need to be processed for a water pump workpiece are usually realized by two clamping processes. To realize the processing of an eccentric circle, the disadvantages brought by the two clamping processing are obvious. First, the work efficiency is reduced. The two clamping wastes the time for loading and unloading the workpiece, which reduces the effective utilization rate of the CNC lathe equipment. It is due to multiple loading and unloading of workpieces, resulting in cumulative errors in the processing process, time-consuming and labor-intensive, low processing accuracy, and sometimes resulting in waste products, which increases processing costs
