Description
Technical field
The utility model relates to field of fixtures, and in particular to a kind of differential casing Internal Spherical Surface turning clamp.
Background technique
Respectively there is a bearing installation outer circle at common automobile differential shell both ends, also have one and axis on differential casing
Two planetary gear shaft holes holding the concentric installation positioning outer circle of installation outer circle and intersecting vertically with bearing installation outer circle, differential mechanism
Case inside has Internal Spherical Surface, and the sphere center position of Internal Spherical Surface is located at the friendship of bearing installation outer circle axis and planetary gear shaft axially bored line
At point.It is fixed inconvenient since differential casing is more complex when turning Internal Spherical Surface, in addition Internal Spherical Surface position degree is more demanding, add
Work process tool acquires a certain degree of difficulty.In order to guarantee that differential casing Internal Spherical Surface turnery processing goes on smoothly and guarantee machining accuracy, need
Want corresponding fixture.
Summary of the invention
Place, the utility model are intended to provide a kind of planet tooth of differential casing in view of the deficiency of the prior art
Axle hole turning clamp, positioning accuracy is high, and stationarity is good, it is ensured that machining accuracy.
In order to achieve the above object, the utility model uses following technical scheme:
A kind of differential casing Internal Spherical Surface turning clamp, it is characterised in that: including bottom plate, angled seat, clump weight, wherein described
Angled seat and clump weight are all set on the bottom plate, and positioned opposite；There is sink hole, in the heavy platform of sink hole in the angled seat
On be provided with support plate for positioning differential casing to be processed, make on the differential casing to be processed to turning planet
Axle hole and the same central axis of the bottom plate, there are also for differential casing to be processed to be pressed on the bearing in the angled seat
Pressing plate on plate, the taper bolt for preventing the differential casing rotation to be processed, the free end of the angled seat, which also has, to be convenient for
The technology groove that cutter protrudes into.
Further, waist type mounting hole is provided on the clump weight, which is cooperated by screw, kidney-shaped mounting hole
And it is adjusted and is mounted on the bottom plate.
Further, there is pin hole corresponding with the taper bolt in the angled seat, and be provided in the pin hole
With the bushing of taper bolt cooperation.
Further, the pressing plate is in inverted L-type, and be provided in the middle part of its longer sides waist-shaped hole and with the waist type
The adjusting bolt that hole matches.
The beneficial effects of the utility model include: the stationarity that adjustable clump weight is arranged on bottom plate and increases fixture,
Machining accuracy is increased, positioning accuracy is high, while clamping workpiece is convenient.

Specific embodiment
Combined with specific embodiments below and attached drawing is further described the utility model.
A kind of differential casing Internal Spherical Surface turning clamp as shown in Fig. 1 to 5, structure includes bottom plate 4, angled seat 1, counterweight
Block 2, wherein the angled seat 1 and clump weight 2 are all set on the bottom plate 4, and positioned opposite.The bottom plate 4 is for being installed on
On the main shaft of lathe, and entire turning clamp is driven to rotate.The angled seat 1 includes vertical part and the horizontal part, wherein the angle
There is sink hole on 1 horizontal part of seat, the support plate for positioning differential casing to be processed is provided in the heavy platform of sink hole
3, make on the differential casing to be processed to turning planetary gear axis hole and the same central axis of the bottom plate 4.In the angled seat 1
There are also for by pressing plate 8 that differential casing to be processed is pressed on the support plate 3, prevent the differential casing to be processed
The taper bolt 12 of rotation.The free end of the angled seat 1 also has the technology groove protruded into convenient for cutter.
In order to guarantee the stationarity of turning clamp, waist type mounting hole is provided on the clump weight 2, which passes through spiral shell
Nail, kidney-shaped mounting hole are adjusted with merging and are mounted on the bottom plate 4, pass through the mounting distance for adjusting clump weight on bottom plate 4
The dynamic balancing of adjustable turning clamp.
There is pin hole corresponding with the taper bolt 12, and setting in the pin hole in the angled seat 1 as shown in Figure 4
There is the bushing 13 with the taper bolt 12 cooperation.On the one hand positioning accuracy that bushing 13 improves the taper bolt 12 is set,
The wearability that another aspect increases fixture makes it, and the service life is longer.
The as shown in Figure 5 pressing plate 8 is in inverted L-type, and be provided in the middle part of its longer sides waist-shaped hole and with the waist
The adjusting bolt that type hole matches, the differential casing to be processed for Quick-clamped.
Technical solution provided by the utility model embodiment is described in detail above, it is used herein specifically
A example is expounded the principle and embodiment of the utility model embodiment, and the explanation of above embodiments is only applicable to help
Assistant solves the principle of the utility model embodiment；At the same time, for those skilled in the art is implemented according to the utility model
Example, there will be changes in terms of specific embodiments and scope of application, in conclusion the content of the present specification should not be construed as
Limitations of the present invention.
