Abstract
The utility model discloses an anchor clamps frock for processing high accuracy impeller pump head, including be used for with machining center lathe fixed connection's bottom plate, the spring that is connected with the bottom plate cover, the tight screw that expands passes through threaded connection with the spring cover that expands, the outer wall of the spring cover that expands and the pump head circle contact extrusion realize pressing from both sides tightly the pump head. The utility model has the advantages of reasonable design, realize the location of pump head through circle in the pump head to in the processing of the pump head surface is once only accomplished at numerical control machining center, thereby reduce the clamping number of times, improve machining efficiency and machining precision.
Description
Technical Field
The utility model belongs to the technical field of the rotor pump manufacturing, concretely relates to an anchor clamps frock for processing high accuracy rotor pump head.
Background
The pump head is the essential spare part of rotor pump, because the interior circle of pump head is direct to contact with the rotor, consequently the required precision of its interior circle is higher, roughness etc. all have certain requirement, the good back of round processing in the pump head, need be to its surface machining, the current frock of processing to the pump head surface, usually not use interior circle as the location, need carry out a lot of clamping number of times, just can accomplish the processing of pump head surface, waste time and energy, simultaneously, machining efficiency greatly reduced, the machining precision is also lower.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the prior art, the utility model aims to provide an anchor clamps frock for processing high accuracy impeller pump head.
The utility model discloses a following technical scheme realizes:
the utility model provides an anchor clamps frock for processing high accuracy rotor pump head, this anchor clamps frock of its characterized in that is including the spring that is used for with machining center lathe fixed connection's bottom plate, is connected with the bottom plate cover that expands, the tight screw that expands passes through threaded connection with the spring cover that expands, and the outer wall of the spring cover that expands is pressed from both sides tight the pump head with the interior round contact extrusion realization of pump head.
The spring expansion sleeve is connected with the bottom plate through a screw.
The expansion screw is conical.
The spring expansion sleeve comprises a connecting block and an expansion block of an integrated structure, and the connecting block is connected with the bottom plate through a screw.
The expansion block is cylindrical.
The spring expansion sleeves and the expansion screws are both provided with two springs, and the two spring expansion sleeves are arranged in the inner circle of the pump head side by side.
The utility model has the advantages of reasonable design, realize the location of pump head through circle in the pump head to in the processing of the pump head surface is once only accomplished at numerical control machining center, thereby reduce the clamping number of times, improve machining efficiency and machining precision.
Drawings
FIG. 1 is a schematic diagram of the overall structure of a pump head;
FIG. 2 is a schematic cross-sectional view of a fixture assembly;
FIG. 3 is an exploded view of the present invention;
in the figure, 1-bottom plate, 2-spring expansion sleeve, 3-expansion screw, 4 screw, 5-connecting block, 6-expansion block and 7-pump head.
Detailed Description
The invention is described in further detail below with reference to the accompanying drawings, and specific embodiments are given.
As shown in FIGS. 1-3, the utility model relates to an anchor clamps frock for processing high accuracy rotor pump head for the processing of rotor pump head surface, this anchor clamps frock including be used for with machining center lathe fixed connection's bottom plate, with the bottom plate through the spring of screw connection cover, the tight screw that expands of toper structure, the tight screw that expands passes through threaded connection with the spring cover that expands, the outer wall of the spring cover that expands realizes pressing from both sides tight to the pump head with the interior round contact extrusion of pump head.
Preferably, the spring expands the cover and includes the connecting block of integral type structure and expands tight piece, and the connecting block passes through the screw to be connected with the bottom plate, expands tight piece and is cylindricly, states the spring and expands the cover and expand tight screw and all be provided with two, and two springs expand the cover and set up side by side in the pump head is interior round.
The utility model discloses utilize interior circle required precision of rotor pump head to high to this fixes a position, processes the surface of pump head. When the tool is used, the spring expansion sleeve is fixed on the bottom plate by using a screw, the spring expansion sleeve and the bottom plate are positioned by using the excircle of the bottom, and then the bottom plate of the tool is fixed on a machine tool of a machining center by using the screw; and then, pre-screwing the expansion screw on the spring expansion sleeve, finally putting the pump head with the inner circle processed and the outer surface ready to be processed on, and screwing the expansion screw after putting. At the moment, the expansion screw moves downwards, and the expansion screw is in a conical structure, so that the spring expansion sleeve is expanded in the downward moving process, the outer circle of the spring expansion sleeve is expanded and is in contact extrusion with the inner circle of the pump head, and the pump head is clamped to process the outer surface. Therefore, finished pump heads can be processed only by one-time clamping, so that the operation efficiency of workers is improved, and the product precision is also improved.
