Description
Technical Field
The invention relates to the technical field of rear pump shell machining, in particular to a positioning tool for a rear pump shell of an internal gear pump.
Background
With the development of a hydraulic system, gear pumps are widely applied, a rear pump shell is used as a supporting part of an internal gear pump, the precision requirement is high, otherwise, when the gear rotates, the oil leakage is too large or the noise exceeds the standard, and the oil pumping function of the gear pump cannot be realized. The original rear pump shell is clamped by three claws, and is manually aligned, so that the labor intensity is high, the consumed time is long, the positioning precision is poor, and the quality is unstable.
Disclosure of Invention
Aiming at the technical problems, the invention provides a positioning tool for a rear pump shell of an internal gear pump, which is designed for the rear pump shell of the internal gear pump, has the advantages of simple structure, high positioning precision and convenience and quickness in use, can effectively ensure the part processing quality, improves the production progress, can greatly reduce the labor intensity, and meets the requirement of batch production of the rear pump shell.
The utility model provides a pump case body location frock behind crescent gear pump, includes location base, locating pin and positioning bolt, the location base is the step axle, and the upper portion square shaft of location base is equipped with the locating hole that uses with the cooperation of the current mounting hole on the rear pump case body, the locating hole includes smooth surface hole and screw hole, the rear pump case body passes through locating pin and positioning bolt to be fixed on the location base, the lower part of location base is the circle axle for connect outside clamping equipment.
Preferably, the positioning pin comprises a cylindrical pin and a diamond pin.
Preferably, in the above aspect, the positioning base is provided with a hollow portion coaxial with the rear pump housing.
The invention has the beneficial effects that:
this location frock is to crescent gear pump case back pump casing design, simple structure, and positioning accuracy is high, and convenient to use is quick, can effectively guarantee parts machining quality, improves the production progress, can greatly reduce intensity of labour again, satisfies the demand of back pump case mass production.
Drawings
FIG. 1 is a cross-sectional view of the present invention in connection with a rear pump housing.
FIG. 2 is a top view of the present invention in connection with a rear pump housing.
The reference numbers are as follows: 1-a positioning base, 2-a positioning pin, 3-a positioning bolt, 4-a positioning hole, 5-a hollow part and 6-a rear pump shell.
Detailed Description
The technical scheme of the invention is clearly and completely described below by combining the attached drawings of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any inventive step, are within the scope of the present invention.
As shown in fig. 1 and 2, the positioning tool for the rear pump shell of the crescent gear pump comprises a positioning base 1, a positioning pin 2 and a positioning bolt 3, wherein the positioning base 1 is a step shaft, the upper square shaft of the positioning base 1 is provided with a positioning hole 4 matched with an existing mounting hole on a rear pump shell 6, the positioning hole 4 comprises a smooth hole and a threaded hole, the rear pump shell 6 is fixed on the positioning base 1 through the positioning pin 2 and the positioning bolt 3, and the lower part of the positioning base 1 is a round shaft and used for being connected with external clamping equipment.
In the present embodiment, the positioning pin 1 includes a cylindrical pin and a diamond pin.
In the present embodiment, the positioning base 1 is provided with a hollow portion 5 coaxial with the rear pump housing 6.
The specific working principle of this embodiment is as follows.
Firstly, a circular shaft at the lower part of the positioning base 1 is clamped and fixed by a three-jaw chuck, and the rear pump housing 6 is positioned and installed on the basis that the positioning base 1 is firmly fixed by the three-jaw chuck. After the mounting hole on the rear pump shell 6 aligns with locating hole 4 on the locating base 1, pack into appointed plain noodles downthehole with cylindric lock and diamond pin earlier, with rear pump shell 6 and the preliminary location of locating base 1, then through positioning bolt 3 with rear pump shell 6 and the locking of locating base 1, accomplish the clamping location of rear pump shell 6 promptly, can begin to process the dysmorphism face of rear pump shell 6.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
