Abstract
The utility model discloses a machining tool for a thin-wall part of a screw pump. The machining tool is arranged on a lathe and used for the turning machining of the thin-wall part, and comprises a sleeve sleeved on the thin-wall part, wherein a gap is arranged on the body of the sleeve in the axial direction, and the sleeve is clamped by a three-jaw chuck of the lathe. By adopting the technical scheme, when the thin-wall part of the screw pump is turned on the lathe, the contact area of the sleeve with the gap and the thin-wall part is larger, so that the thin-wall part does not easily deform, the machining precision is improved, the dimension tolerance of the thin-wall part is ensured, and the clamping positioning can be stable.
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 tool that is used for the thin-wall part on the screw pump.
Background technology
At present, the thin-wall part that is used on the screw pump needs to process on lathe via blank, as is enclosed within the protective sleeve on the driving shaft; When the enterprising driving of lathe is cut, be the mode that adopts traditional three-jaw clamping thin-wall part periphery, still; Under the clamping force effect of chuck, because the contact area of chuck and thin-wall part is little, thin-wall part is prone to deform; Thereby influence machining accuracy, the dimensional tolerance of thin-wall part is difficult for guaranteeing, and clamping and positioning is unstable.
The utility model content
The utility model technical problem to be solved provides a kind of processing tool that is used for the thin-wall part on the screw pump, adds the purpose that be difficult for deforming during thin-wall part man-hour to reach in turning.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of processing tool that is used for the thin-wall part on the screw pump; Be located on the lathe, be used for the turning processing of thin-wall part, said processing tool comprises a sleeve that is enclosed within on the said thin-wall part; This sleeve is axially arranged with a slit in its body upper edge, and this sleeve and the scroll chuck that passes through on the said lathe clamp.
The utility model adopts technique scheme, and during the thin-wall part of turning screw pump, the contact area of crack sleeve and thin-wall part is bigger on lathe; Make thin-wall part be difficult for deforming; Improve its machining accuracy, guarantee the dimensional tolerance of thin-wall part, can also make clamping and positioning stable.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the sleeve of the utility model;
Mark among the above-mentioned figure is: 1, scroll chuck; 2, sleeve; 3, thin-wall part.
The specific embodiment
As depicted in figs. 1 and 2; A kind of processing tool that is used for the thin-wall part on the screw pump of the utility model; Be located on the lathe, be used for the turning processing of thin-wall part 3, processing tool comprises a sleeve 2 that is enclosed within on the thin-wall part 3; This sleeve 2 is axially arranged with a slit in its body upper edge, and this sleeve 2 and the scroll chuck 1 that passes through on the lathe clamp.Adding man-hour, sleeve 2 is placed on clamping on the scroll chuck 1, then thin-wall part 3 is being inserted in the endoporus of sleeves 2, through scroll chuck 1 closing sleeve 2, because sleeve 2 is provided with aperture slots, sleeve 2 contraction distortion under the clamping force effect clamps thin-wall part 3 then.Adopt this frock, during the thin-wall part 3 of turning screw pump, the sleeve 2 that cracks is bigger with the contact area of thin-wall part 3, makes thin-wall part 3 be difficult for deforming, and improves its machining accuracy, guarantees the dimensional tolerance of thin-wall part 3 on lathe, can also make clamping and positioning stable.
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.
