Abstract
The utility model discloses a high-precision hub positioning fixture which is matched with an automobile hub. One end of the high-precision hub positioning fixture is provided with a claw plate which is matched and fixed with the hub. The other end of the high-precision hub positioning fixture is provided with a positioning plate which is matched and fixed with a machine tool fixture. The claw plate is provided with spoke grooves which are in accurate fit with spokes of the hub. A positioning protruding seat is arranged at the center of the positioning plate. The high-precision hub positioning fixture is in close fit with the hub, therefore, sliding in a machining process is prevented, positioning accuracy is increased, and machining quality of the hub is improved.
Description
Technical field
The utility model relates to a kind of positioning fixture, relates in particular to a kind of high accuracy wheel hub positioning fixture.
Background technology
In the wheel hub production process, Digit Control Machine Tool carries out machining on the needs, existing locate mode is for adopting the three-point fix piece, be clamped in the earflap position of wheel hub, because earflap is thinner, the distortion that easily appearance is bigger in casting and heat treatment process or damage is located with the clamping earflap, it is inaccurate to cause wheel hub to add man-hour location easily, and it is bad to cause processing the rear-wheel hub dynamic balancing.
The utility model content
The purpose of this utility model is to provide a kind of wheel hub positioning fixture, to improve positioning accuracy, promotes the wheel hub quality.
For achieving the above object, the utility model is by the following technical solutions:
High accuracy wheel hub positioning fixture, cooperate with automotive hub, the one end is to cooperate fixing pawl dish with wheel hub, and the other end is to cooperate fixing positioning disk with the lathe tool, described pawl dish is provided with the spoke groove that accurately cooperates with the spoke of wheel hub, and described positioning disk center is provided with the protruding seat in location.
Wherein, described positioning disk is provided with some equally distributed bolts hole, and described pawl dish is provided with the containing hole corresponding with described bolt hole.
After adopting technique scheme, the utlity model has following beneficial effect:
1. the pawl dish is provided with the spoke groove that accurately cooperates with the spoke of wheel hub, and wheel hub is cooperated closely with anchor clamps, prevents sliding position in mechanical processing process, has improved positioning accuracy.
2. the positioning disk center is provided with the protruding seat in location, locate protruding seat and match with base groove on the Digit Control Machine Tool, pass through positioning disk upper bolt hole fixing and locking with bolt, guaranteed the same axis in center of anchor clamps and lathe, further improve machining accuracy, promote the crudy of wheel hub.
Description of drawings
Fig. 1 looks schematic diagram for master of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the schematic diagram that the utility model cooperates with wheel hub;
Fig. 4 is installed in schematic diagram on the lathe tool for the utility model.
The primary clustering symbol description:
10: pawl dish, 11: spoke groove, 12: containing hole, 20: positioning disk, 21: locate protruding seat, 22: bolt hole, 30: wheel hub, 31: spoke, 32: earflap, 40: grip block
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also Fig. 1, shown in Figure 2, this is novel to disclose a kind of high accuracy wheel hub positioning fixture, cooperates with automotive hub, is used for the wheel hub installation is positioned at carrying out machining on the Digit Control Machine Tool.One end of this positioning fixture is to cooperate fixing pawl dish 10 with wheel hub 30, and the other end is to cooperate fixing positioning disk 20 with the lathe tool, and pawl dish 10 is provided with the spoke groove 11 that accurately cooperates with the spoke 31 of wheel hub 30, and positioning disk 20 centers are provided with the protruding seat 21 in location.This positioning fixture and wheel hub 30 fiting effects are as shown in Figure 3.Positioning disk 20 is provided with some equally distributed bolts hole 22, and pawl dish 10 is provided with the containing hole 12 corresponding with bolt hole 22, and the bolt hole 22 of present embodiment and the quantity of containing hole 12 respectively are four.
As Fig. 4, during installation, earlier this positioning fixture is installed on the lathe tool, positioning disk 20 cooperates the location with the lathe tool, the protruding seat in location 21 is matched with central recess on the tool, select for use four bolts to insert from the containing hole 12 on the pawl dish 10 and just lock on bolt hole 22, this positioning fixture is locked on the lathe tool.Wheel hub 30 then is installed, the spoke 31 of wheel hub 30 is corresponding with the pawl dish 10 of this positioning fixture, spoke groove 11 is just in time accurately cooperated one by one with spoke 31, be clamped on the earflap 32 of wheel hub 30 fixing by three grip blocks 40 on the lathe.This locate mode is stable, the positioning accuracy height, and the crudy of wheel hub is improved, and has guaranteed that the dynamic balancing parameter of wheel hub meets the requirements.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
