Abstract
The utility model discloses a processing and positioning tool used for a connecting shaft on a screw pump. The connecting shaft is arranged on a lathe, and the processing and positioning tool comprises a three-jaw chuck, a back tip and a front tip, wherein the front tip and the back tip are respectively propped to the center of a circle of two end surfaces of the connecting shaft, and the front tip is clamped on the three-jaw chuck. According to the technical scheme, two tips are respectively propped at the two ends of the connecting shaft and are not directly clamped by the three-jaw chuck of the lathe, the front tip and the back tip are clamped with the connecting shaft, and a lathe main shaft only plays a role of driving and can avoid processing errors caused by main shaft rotation errors so as to improve the processing accuracy and keep the coaxiality of the connecting shaft.
Description
Technical field
The utility model relates to the production equipment of screw pump and parts thereof, and specifically, the utility model relates to a kind of processing positioning tool that is used for the connecting axle on the screw pump.
Background technology
At present, being used for connecting axle on the screw pump and cutting in the enterprising driving of lathe and add man-hour, is through scroll chuck on the lathe and back centre connecting axle to be positioned; Adopt this kind locate mode; The lathe spindle revolution owing to the existence of lathe spindle turn error, is easy to generate the mismachining tolerance of connecting axle; Influence the axiality of connecting axle, reduce the machining accuracy of connecting axle.
The utility model content
The utility model technical problem to be solved provides a kind of processing positioning tool that is used for the connecting axle on the screw pump, improves the connecting axle machining accuracy to reach, and keeps the purpose of the axiality of connecting axle.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of processing positioning tool that is used for the connecting axle on the screw pump; Said connecting axle is placed on the lathe, and said processing positioning tool comprises scroll chuck and back centre, and is top before also comprising one; Top and back centre withstand on the circle centre position of the both ends of the surface of said connecting axle respectively before said, and be top and be clamped on the said scroll chuck before said.
The utility model adopts technique scheme; Through two top two ends that withstand on connecting axle respectively are set, rather than the directly scroll chuck clamping through lathe, forward and backward top clamping connecting axle; Lathe spindle only serves to spur; The mismachining tolerance that can avoid spindle rotation error to cause, thus machining accuracy improved, keep the axiality of connecting axle.
Description of drawings
Fig. 1 is the utility model structural representation;
Mark among the above-mentioned figure is: 1, scroll chuck; 2, preceding top; 3, connecting axle; 4, back centre.
The specific embodiment
As shown in Figure 1; A kind of processing positioning tool that is used for the connecting axle on the screw pump of the utility model; Connecting axle 3 is placed on the lathe; This processing positioning tool comprises before scroll chuck 1, the back centre 4 and top 2, and top 2 withstand on the circle centre position of the both ends of the surface of connecting axle 3 respectively with back centre 4 before this, preceding top 2 and be clamped on the scroll chuck 1.The processing positioning tool of connecting axle 3 adopts this structure; Through two top two ends that withstand on connecting axle 3 respectively are set, rather than directly scroll chuck 1 clamping through lathe, forward and backward top clamping connecting axle 3; Lathe spindle only serves to spur; The mismachining tolerance that can avoid spindle rotation error to cause, thus machining accuracy improved, keep the axiality of connecting axle 3.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the method design of the utility model and the improvement of the various unsubstantialities that technical scheme is carried out; Or the design of the utility model and technical scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
Claims (1)
