Abstract

The utility model belongs to the technical equipment of mechanical machining, in particular relates to a tool for machining a thin and long damping hole of a pump body. The tool comprises an opening flat gasket (3) and a lock nut (4). Two ends of a clamping core shaft (2) of the tool for machining the thin and long damping hole of the pump body are respectively provided with threads, one end of the clamping core shaft (2) is in threaded connection with a thread hole in a vertical plate of a base bending plate (1), a pump body (9) is penetrated on the clamping core shaft (2), the pump body (9) is fixed on the base bending plate (1) by the opening flat gasket (3) and the lock nut (4), the thin end of a positioning core shaft (5) is connected with a hole on a mould drilling bending plate (6) by means of interference fit, the other end of the positioning core shaft (5) is connected with a valve hole of the pump body (9) by means of clearance fit, and a drilling bush (7) is embedded into a hole of the position of the damping hole to be machined corresponding to the upper plane of the mould drilling bending plate (6) by means of interference fit. After the tool for machining the thin and long damping hole of the pump body is used, the work efficiency is improved, the waste product is completely eradicated, the machining cost is reduced, and the product quality is guaranteed.

Description

The elongated damping hole processing tool of the pump housing
Technical field
The utility model belongs to mechanical processing technique equipment, the elongated damping hole processing tool of particularly a kind of pump housing.
Background technology
The machined surface of this damping hole is an arc convex surface, add and be difficult for the location man-hour, and this hole is elongated flowing hole, also to pass through valve opening in the process, therefore cause drill bit usually to fold in the hole of processing, the whole pump housing is scrapped, therefore neither guarantee precision man-hour easily adding, improve percent defective again, increased processing cost simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of and can guarantee machining accuracy, the rate of reducing the number of rejects and seconds, the elongated damping hole processing tool of the pump housing simple in structure.
The utility model technical solution problem adopts technical scheme to be: the elongated damping hole processing tool of the pump housing comprises the opening plain cushion, locking nut, the two ends that are characterized in the clamping mandrel of the elongated damping hole processing tool of the pump housing are respectively equipped with screw thread, threaded one end connects the riser neutral threaded hole of base bent plate, the pump housing is installed on and clamps on the mandrel, with opening plain cushion and locking nut the pump housing is fixed on the base bent plate, the thin end of positioning core axle is connected with hole interference fit on the drill jig bent plate, the other end is connected with pump housing valve opening matched in clearance, and the drill bushing interference fit is bumped on the drill jig bent plate in the hole of plane corresponding to damping hole to be processed position.
The beneficial effects of the utility model are: the elongated damping hole processing tool of the pump housing has remedied the deficiency on original processing method, the clamping force equilibrium, processing steadily, hole site after the processing is accurate, is difficult for sideslip, has avoided the phenomenon of drill bit folding in the hole of processing, improved operating efficiency, stop waste product, reduced processing cost, guaranteed product quality.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is the structural front view of the elongated damping hole processing tool of the pump housing.
Fig. 2 is the left view of Fig. 1.
Among the figure, 1-base bent plate; 2-clamps mandrel; 3-opening plain cushion; The 4-locking nut; The 5-positioning core axle; 6-drill jig bent plate; The 7-drill bushing; 8-damping hole to be processed; The 9-pump housing;
The specific embodiment
Embodiment, with reference to accompanying drawing 1,2, the two ends of the clamping mandrel 2 of the elongated damping hole processing tool of the pump housing are respectively equipped with screw thread, threaded one end connects the middle screwed hole of riser of base bent plate 1, the pump housing 9 is installed on and clamps on the mandrel 2, with opening plain cushion 3 and locking nut 4 pump housing 9 is fixed on the base bent plate 1.The thin end of positioning core axle 5 is connected with the hole interference fit of drill jig bent plate 6, the other end is connected with the pump housing 9 valve opening matched in clearance, drill bushing 7 interference fit are bumped on the drill jig bent plate 6 in the hole of plane corresponding to damping hole to be processed 8 positions, and drill bit is by drill bushing 7 processing damping hole 8 to be processed.
