Abstract
The utility model relates to a wheel hub processing apparatus, and specifically relates to a wheel hub flatness testing fixture. The wheel hub flatness testing fixture comprises a first flat plate and a second flat plate which are in mutual parallel arrangement, and telescoping rods and telescoping sleeves which are used for connecting the first flat plate and the second flat plate. The second flat plate is provided with a support bench, and the support bench is connected with the second flat plate through a support bar; the bottom side of the first flat plate is provided with a compaction block, the axis of the compaction block maintains consistent with the axis of a wheel hub, and the compaction block is pressed downwards along with the first flat plate to cover the wheel rim surface of the wheel hub; and the outer side of the wheel hub is provided with four detection pins which abut against the wheel hub and are in cross-shaped arrangement, and one end of each detection pin forms a rotary cooperation relation with the telescoping sleeve. According to the utility model, through arrangement of the spherical-shaped compaction block, the wheel hub, when being clamped, can bear uniform forces and does not shake. Through the cooperation between the telescoping rod and the telescoping sleeve, the downward pressing of the compaction block is more stable and accurate, and detection errors are avoided. Through the improvement of the structure of the detection pins, the flatness detection accuracy is further improved.
Description
Technical field
The utility model relates to a kind of wheel hub processing unit (plant), specifically relates to a kind of wheel hub flatness cubing.
Background technology
In wheel hub manufacture field, for the detection of its outer ring surface evenness, generally complete by cubing, such cubing comprises test pin and clamp device, this clamp device mainly exists clamping efficiency low, and clamping rear-wheel hub easily rocks and the defect such as causes accurately detecting.
Utility model content
For the technical matters existing in prior art, the purpose of this utility model is to provide a kind of wheel hub flatness cubing.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of wheel hub flatness cubing, the first flat board that comprising is parallel to each other arranges is with the second flat board, for being connected both several expansion links that cooperatively interact and extension sleeve, on described the second flat board, be provided with the brace table for placing wheel hub, described brace table is by support bar and the second dull and stereotyped connection; The bottom side of described the first flat board is provided with the compact heap that is dome shape, and the axis of described compact heap and the axis of wheel hub are consistent, and described compact heap presses down the wheel rim surface that is covered on described wheel hub with the first flat board;
The arranged outside of described wheel hub has four of connecting with it to be the test pin that cruciform is arranged, and one end of described test pin and extension sleeve form the relation that is rotatably assorted;
Described test pin comprises the first cone, the first right cylinder, the second right cylinder, three cylindrical body, the second cone, the 4th right cylinder, Three-cone, the 5th right cylinder, the 6th right cylinder and the 7th right cylinder that is global formation adjacent one another are;
Described the first cone, the first right cylinder, the second right cylinder, three cylindrical body, the second cone, the 4th right cylinder, Three-cone, the 5th right cylinder, the 6th right cylinder and the 7th cylindrical Length Ratio are 0.95:1.15:0.35:0.45:0.95:0.85:0.95:1.15:0.35:0.45.
Wheel hub flatness cubing of the present utility model, its beneficial effect shows:
Be the compact heap of dome shape by setting, make wheel hub in the time being held, can uniform stressed, there will not be the phenomenon of rocking.By the cooperation of expansion link and extension sleeve, make pressing down of compact heap more steady, accurate, to avoid detecting the appearance of error.By improving test pin structure, the accuracy detecting further to improve flatness.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of test pin.
Embodiment
For further describing the utility model, below in conjunction with drawings and Examples, the utility model is described in further detail.A kind of wheel hub flatness cubing shown in Fig. 1 and 2, the first flat board 10 that comprising is parallel to each other arranges is with the second flat board 50, for being connected both several expansion links that cooperatively interact 30 and extension sleeve 40, on described the second flat board 50, be provided with the brace table 70 for placing wheel hub 80, described brace table 70 is connected with second dull and stereotyped 50 by support bar 60; The bottom side of described the first flat board 10 is provided with the compact heap 20 that is dome shape, and the axis of the axis of described compact heap 20 and wheel hub 80 is consistent, and described compact heap 20 presses down the wheel rim surface that is covered on described wheel hub 80 with the first flat board 10.
