Abstract
The utility model discloses a tool for machining an indoor spherical surface of an impeller of a submersible mixed-flow pump. The tool comprises a support base, a locating sleeve is rotationally arranged at the upper end of the support base, and the locating sleeve rotates around the supporting base; the locating sleeve is connected with a connecting rod through a locating pin, and the connecting rod rotate around the locating pin; the connecting rod is provided with a strip-shaped slot in which a sliding block is arranged in a sliding manner, an arc knife rest is connected with the bottom end of the connecting rod, and a turning tool is arranged on the knife rest. The tool disclosed by the utility model has the advantages of simple design, convenience for operation, capabilities of machining inner spherical surfaces and ensuring the machining precision, and convenience for installation and regulation.
Description
Technical field
The utility model mainly is the frock of the indoor sphere processing of a kind of mixed flow impeller of electrical pump of diving under water.
Background technology
Large diving mixed flow impeller of electrical pump chamber is because size is big; Required precision is high; Be not suitable on numerically controlled lathe, processing through programming, blade wheel chamber's two end flanges, seam can process on common vertical lathe, and Internal Spherical Surface can not directly process on lathe; Therefore, formulating reasonable process technology and design is equipped with necessary and simple and convenient processing Internal Spherical Surface frock is desirable solution.
The utility model content
The utility model technical problem to be solved provides the frock of the indoor sphere processing of a kind of mixed flow impeller of electrical pump of diving under water, and its structural design is simple but easy to operate, and the precision that can process Internal Spherical Surface and can guarantee to process is installed and is convenient to regulate.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
The frock of the indoor sphere processing of a kind of mixed flow impeller of electrical pump of diving under water includes supporting seat, and the upper end of said supporting seat is rotatablely equipped with positioning sleeve, and described positioning sleeve rotates around supporting seat; Be connected with connecting rod through alignment pin on the described positioning sleeve, described connecting rod rotates around alignment pin; Have bar-shaped trough on the described connecting rod, be slidingly fitted with slide block in the bar-shaped trough, the bottom of described connecting rod is connected with curve forming rest, on the described knife rest lathe tool is installed.
It is to leave appropriate gap between through the hole with alignment pin and positioning sleeve, connecting rod to realize that described connecting rod rotates around alignment pin.
The centre of sphere of sphere to be processed is on the center line of alignment pin.
Specific position in view of blade wheel chamber's Internal Spherical Surface linner ball heart; Must the center of sphere on the pivot of frock and the workpiece is consistent during designing car sphere frock;, the connection of frock guarantees that like this lathe tool along the operation of sphere track, just can go out the sphere car as long as the point of a knife and the distance of pivot are adjusted to the size the same with spherical radius when rotating.On processing technology, should blade wheel chamber's two end flanges, seam equidimension be processed on common vertical lathe earlier, Internal Spherical Surface is equipped with the utility model processing at last.
Supporting seat lower end and Lathe bench locating hole are located and are compressed with T-shape bolt and stationary table in the utility model; The motion of connecting rod is caused by the slide block movement on it, and slide block can slide in the bar-shaped trough of connecting rod, drives connecting rod and makes circular motion around the centre of sphere, and like this, the track that the lathe tool of connecting rod end is passed by must be a sphere.The action of slide block receives to be produced by the tool holder of lathe traction, and the one side Lathe bench rotatablely moves during turning, is that frock drive lathe tool moves on sphere on the other hand, and the resultant motion of the two is exactly a sphere.
When using the utility model workpiece (blade wheel chamber) and frock are installed on the rotary table of vertical lathe, join the concentricity that mode that car goes out can guarantee frock and workpiece through calibration of workpieces car seam, frock supporting seat bottom surface and Lathe bench locating hole reality.In addition, owing to taken into full account axial dimension during the Design and Machining frock, the height H of frock pivot is controlled in the rational margin of tolerance.Car sphere frock overall size should be decided according to workpiece size, considers the restriction of institute's apolegamy lathe specification simultaneously, should be in the machined into scope.
In the utility model supporting seat by round steel and steel plate integrally welded after whole again each fit dimension of processing, positioning sleeve adopts round steel to process, one of stage casing excision in case connecting rod interferes when going downwards to certain position, causes workpiece sphere hypomere car not go out.Appropriate gap is left in the hole of alignment pin and positioning sleeve, connecting rod, makes the connecting rod can flexible motion, is not easy to produce vibration again.Slide block cooperates with the locating slot of connecting rod should have certain interval, and it is high that the mating surface machining accuracy is wanted, to guarantee flexible operation.
The basic principle that the frock design will be followed is exactly the quality that guarantees product; Operating efficiency; The safety of the person and equipment and the economic benefit of whole production; Based on above basic principle, when this type of frock of design, should note following requirements: the specificity of frock and complexity will adapt with the production lot of workpiece; Frock should satisfy the requirement to machining accuracy of quality and the manufacturing procedure of product parts design drawing; Under the prerequisite that satisfies requirements such as product zero machining accuracy, efficient, should make every effort to simple in structure, improve the manufacturability that frock is made; Adopt standard component as far as possible, make frock component specificationization, typification, and make whole frock modularization, shorten the manufacturing cycle, reduce cost.
The utility model has the advantages that:
The utility model structural design is simple but easy to operate, and the precision that can process Internal Spherical Surface and can guarantee to process is installed and is convenient to regulate.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Participate in Fig. 1, the frock of the indoor sphere processing of a kind of mixed flow impeller of electrical pump of diving under water includes supporting seat 1, and the upper end of said supporting seat 1 is rotatablely equipped with positioning sleeve 2, and described positioning sleeve 2 rotates around supporting seat 1; Be connected with connecting rod 4 through alignment pin 3 on the described positioning sleeve 2, described connecting rod 4 rotates around alignment pin 3; Have bar-shaped trough 5 on the described connecting rod 4, be slidingly fitted with slide block 6 in the bar-shaped trough 5, the bottom of described connecting rod 4 is connected with curve forming rest 7, on the described knife rest 7 lathe tool 8 is installed.
It is to leave appropriate gap between through the hole with alignment pin 3 and positioning sleeve 2, connecting rod 4 to realize that described connecting rod 4 rotates around alignment pin 3.
The centre of sphere of sphere 9 to be processed is on the center line of alignment pin 3.
