Abstract
The utility model discloses the two top fixtures that a kind of top circle and end face need grinding, comprise axle, the middle part of described axle is provided with stopper section, right part is provided with support column portion, described support column portion is arranged with a ringfeder, and ringfeder is provided with the mesopore corresponding to described working hole, and the right part of the right side in support column portion and described ringfeder is also provided with flat key, the outside of described ringfeder is gear workpieces, and the madial wall of ringfeder is the sliding surface of coupling support column portion excircle; Described working hole is provided with shouldered tap bolt, and this shouldered tap bolt promotes ringfeder through ringfeder and ringfeder is extended out, and then holds out against described gear workpieces.The utility model tool structure is simple, convenient mounting and clamping, is easy to realize, and frock ringfeder is located, and positioning precision is high.
Description
Technical field
The utility model relates to a kind of top circle and end face needs two of grinding to push up fixtures.
Background technology
Along with rising fast of automobile pollution, the demand of automobile market to auto parts and components also increases rapidly, ensureing that the prerequisite of product quality puts, the working (machining) efficiency of raising auto parts and components high as far as possible becomes the target of each auto parts machinery manufacturing enterprise pursuit.
But in actual production process, there is a lot of product gear series products that especially difficulty of processing is large cannot be processed by traditional installation way, and design specialized frock is too complicated, production cost is added to auto parts machinery enterprise, especially when to gear workpieces grinding, traditional clamping structure cannot be accomplished to be completely fixed gear workpieces, thus causes grinding to produce deviation, while reducing product quality, also reduce the competitiveness of enterprise.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, proposes the two top fixtures that a kind of top circle and end face need grinding.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of top circle and end face need two top fixtures of grinding, comprise axle, the middle part of described axle is provided with axial working hole, left part is provided with installation portion, middle part is provided with stopper section, and right part is provided with support column portion, and the cylindrical external diameter in described support column portion diminishes formation inclined plane from left to right gradually; Described support column portion is arranged with a ringfeder, ringfeder is provided with the mesopore corresponding to described working hole, and the right part of the right side in support column portion and described ringfeder is also provided with flat key, the outside of described ringfeder is gear workpieces, and the madial wall of ringfeder is the sliding surface of coupling support column portion excircle; Described working hole is provided with shouldered tap bolt, and this shouldered tap bolt passes the mesopore of ringfeder and to its promotion ringfeder along the slip in support column portion, ringfeder is extended out, and then laminating holds out against the inner headed face of described gear workpieces.
Compared with prior art, the utility model shouldered tap bolt compresses ringfeder, makes gear workpieces and ringfeder cylindrical coordinate, be adjacent to, completes workpiece end face location, thus realize Product processing, gear can not be rotated in grinding process; The gear that this fixture is applicable to all size needs the two top processing on numerical control external cylindrical grinding machine of grinding cylindrical or end face.Tool structure is simple, convenient mounting and clamping, is easy to realize, and frock ringfeder and operative end surface location, positioning precision is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, a kind of top circle that the utility model proposes and end face need two top fixtures of grinding, comprise axle 1, the middle part of axle 1 is provided with axial working hole, left part is provided with installation portion 11, middle part is provided with stopper section 12, and right part is provided with support column portion 13, and the cylindrical external diameter in support column portion diminishes formation inclined plane from left to right gradually; Support column portion is arranged with a ringfeder 2, ringfeder is provided with the mesopore corresponding to working hole, and the right part of the right side in support column portion and ringfeder 2 is also provided with flat key 3, the outside of ringfeder is gear workpieces 4, and the madial wall of ringfeder is the sliding surface of coupling support column portion excircle; Working hole is provided with shouldered tap bolt 5, this shouldered tap bolt 5 passes the mesopore of ringfeder and to its promotion ringfeder 2 along the slip in support column portion, ringfeder is extended out, and then holds out against described gear workpieces 4.
In the utility model, shouldered tap bolt 5 is through ringfeder 2 mesopore, penetrate into again in working hole, shouldered tap bolt 5 and working hole adopt and are threaded, when shouldered tap bolt 5 screws in, the ring shoulder 51 of shouldered tap bolt 5 just blocks on mesopore, and then promotion ringfeder 2 slides in support column portion 13, while slip, ringfeder constantly extends out and becomes large, and then the periphery of ringfeder holds out against in the inner circle of gear workpieces 4, gear workpieces 4 is fixed gear workpiece, when ringfeder and gear workpieces 4 hold out against, just gear workpieces is fixed, complete frock, the conduct of flat key 3 can prevent ringfeder from rotating when sliding, ensure that gear workpieces 4 can not rotate in grinding process, installing hole 41 on gear workpieces can be fixed in addition.
Above-described embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the utility model patent and protection domain should be as the criterion with appended claims.
