The fixture includes clamp base, clamping plate, sliding shoe, the first bolt, the second bolt, spring and anvil block, fixture bottom
Seat is conical boss, and through hole is provided among clamp base and is used to install bend test device；Clamping plate by the first bolt and
Second bolt is arranged in clamp base, and clamp base is arranged on anvil center, and anvil block is recessed provided with circumference symmetrical four
Groove, groove are engaged with sliding shoe, and the groove is used for circumferential constraint and the guide function of sliding shoe；Clamping plate and clamp base it
Between spring is set.Clamp base is designed with through hole with chopping block center, for installing the loading device of crooked experiment.
Clamping plate is provided with positioning hole and guide rod, clamping plate is slided together with sliding shoe, and when tightening the first bolt
Downward clamping wheel hub.
The clamping device that clamping plate, spring, sliding shoe, the first bolt and the second bolt form, circumference are symmetrically distributed in anvil
On four grooves of seat.
Spring is arranged on the guide rod of clamping plate.

Embodiment
To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
The utility model provides a kind of fixture that repeated bend test is carried out for wheel hub.
As shown in Figure 1, Figure 2 and Figure 3, in the fixture, clamp base 2 is conical boss, makes the more preferable centering of wheel hub, and
The circular runout of wheel hub is constrained, clamp base 2 is designed with through hole with the center of chopping block 1, for installing the loading device of crooked experiment；
Clamping plate 3 is arranged in clamp base 2 by the first bolt 6 and the second bolt 7, and clamp base 2 is arranged on the center of anvil block 1, anvil
Seat 1 is provided with four symmetrical grooves of circumference, and the groove is used for circumferential constraint and the guide function of sliding shoe, and groove is with sliding
Block 5 is engaged；Spring 4 is set between clamping plate 3 and clamp base 2.
Clamping plate 3 is provided with positioning hole and guide rod, clamping plate 3 is slided together with sliding shoe 5, and is tightening the first bolt
Downward clamping wheel hub 8 when 6.
The clamping device that clamping plate 3, spring 4, sliding shoe 5, the first bolt 6 and the second bolt 7 form, circumference are symmetrical
On 1 four grooves of anvil block.
Spring 4 is arranged on the guide rod of clamping plate 3, is played a supporting role.
Sliding shoe 5 is provided with pilot hole, the first screwed hole and the second screwed hole；The positioning that first bolt 6 passes through clamping plate 3
Hole and the first screwed hole of sliding shoe 5 coordinate；Second screwed hole of the second bolt 7 and sliding shoe 5 coordinates, constraint sliding shoe 5
Horizontal displacement.
During experiment, wheel hub 8 is placed in clamp base 2 first, makes the keep level of wheel hub 8, wheel hub 8 and clamp base 2
Will automatic centering, then by the slid inward of sliding shoe 5 in four grooves, when the front end of clamping plate 3 is slided into above the wheel rim of wheel hub 8
When, tighten the first bolt 6 and the second bolt 7.So wheel hub 8 by repeated bend test test load when, footpath will not be produced
To bounce, it is convenient that wheel hub 8 clamps, and centering is accurate, improves test accuracy.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of principle described in the utility model is not departed from, some improvements and modifications can also be made, these improvement
