Abstract

The utility model discloses a positioning clamp for bearing seat hole boring. The positioning clamp for bearing seat hole boring comprises a four-jaw chuck. Four jaws which are distributed in the radial direction are evenly arranged on the four-jaw chuck and drive the four-jaw chuck to move through lead screws. The front end of one jaw is provided with a positioning baffle which is vertical to the jaw and the front end face of the positioning baffle is a smooth positioning plane. When a smooth bottom face of a bearing seat adheres to the positioning plane of the positioning baffle, a bearing seat hole of the bearing seat is coincidentally coaxial with the four-jaw chuck. Compared with the prior art, the positioning clamp for bearing seat hole boring has the advantages that accurate positioning in the time of bearing seat hole boring can be achieved as the front end of one jaw of the four-jaw chuck is welded with the positioning baffle vertical to the jaw, thus the requirement for size precision of the bearing seat hole and the requirement for distance size precision with the bottom face of the bearing seat are met and the high-precision requirement for machining parts can be met. In addition, the positioning clamp is simple in structure, low in support cost, convenient to use in clamping and positioning, capable of saving time and labor and suitable for popularization and application.

Description

Bearing block bore hole positioning fixture
Technical field
The utility model relates to machining technique field, in particular bearing block bore hole positioning fixture.
Background technology
Bearing block is the supporting and location parts of power transmission shaft, the stationarity of whole operation process, durability, carrying are stressed etc. guarantees entirely by bearing block, therefore the requirement of the accuracy of manufacture of bearing block is very high, wherein the distance size of bearing saddle bore dimensional tolerance and bearing saddle bore axis and bearing block bottom surface is had to very high required precision.At present to the processing of bearing saddle bore, generally all adopt boring machine or milling machine to process.But conventionally fluted in the middle of bearing block bottom, its groove inner bottom surface is coarse injustice often, if directly adopt the chuck on boring machine to position it, because the claw front end face area of chuck is very little, can not play accurate positioning action, and groove position that can only engagement shaft bearing bottom surface, and the coarse injustice of groove inner bottom surface, be difficult to guarantee the machining accuracy of bearing saddle bore.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, positioning precision is high, clamping location convenient, the dimension precision requirement that guaranteed bearing saddle bore with and with the bearing block bore hole positioning fixture of the distance dimension precision requirement of bearing block bottom surface.
The utility model is achieved through the following technical solutions:
Bearing block bore hole positioning fixture, comprise a chuck, on described chuck, be evenly provided with four claws that radially distribute, described claw drives it to move by screw mandrel, at described one of them claw front end, be provided with the positioning baffle vertical with described claw, described positioning baffle front end face is smooth plane of orientation, when the smooth bottom surface of bearing block and the plane of orientation of described positioning baffle fit, the bearing saddle bore of bearing block just in time with chuck concentric.
As further optimization of the present utility model, described positioning baffle is welded on one of them claw front end.
As further optimization of the present utility model, four claws of described chuck can move separately.
The utility model has the following advantages compared to existing technology:
The bearing block bore hole positioning fixture that the utility model provides, by the perpendicular positioning baffle of one of them claw front end welding at original chuck, the plane of orientation laminating that during location, the smooth bottom surface of bearing block and positioning baffle front end are smooth, and make bearing saddle bore and chuck concentric, and under the acting in conjunction of its excess-three claw, thereby the accurate location while realizing bearing block bore hole, and then the dimension precision requirement that has guaranteed bearing saddle bore with and with the distance dimension precision requirement of bearing block bottom surface, guaranteed the high-precision requirement of processing parts.In addition, this positioning fixture structure is simple, and bearing cost is low, and clamping location is convenient, time saving and energy saving, is suitable for applying.
Accompanying drawing explanation
Fig. 1 is the utility model positioning bearing seat structural representation.
The specific embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Referring to Fig. 1, the bearing block bore hole positioning fixture that the utility model provides, comprises a chuck 1, is evenly provided with four claws 2 that radially distribute on chuck 1, and claw 2 drives it to move by screw mandrel, and four claws 2 can move separately.Claw 2 front ends are welded with a positioning baffle vertical with this claw 23 therein, and positioning baffle 3 front end faces are smooth plane of orientation.Bearing block 4 is fluted 41 in the middle of bottoms, the coarse injustice of groove 41 inner bottom surface, and bearing block 4 two ends, bottom are accurately machined smooth bottom surface 42.When the smooth bottom surface 42 of bearing block 4 and the plane of orientation of positioning baffle 3 fit, the bearing saddle bore 43 of bearing block 4 just in time with chuck 1 concentric.
During location, the plane of orientation that the smooth bottom surface of bearing block 4 42 and positioning baffle 3 front ends are smooth is fitted, and make the bearing saddle bore 43 and chuck 1 concentric of bearing block 4, then by its excess-three claw 2, clamped just and can realize accurate location.Finally chuck 1 is packed into and on boring machine, carry out boring operation.The positioning fixture providing by the utility model is realized accurately location to bearing block 4, so the dimension precision requirement that has guaranteed bearing saddle bore 43 with and with the distance dimension precision requirement of the smooth bottom surface 42 of bearing block 4, guaranteed the high-precision requirement of processing parts.In addition, this positioning fixture structure is simple, and cost of manufacture is low, and clamping location is convenient, time saving and energy saving, is suitable for applying.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
