Description
Technical Field
The patent of the utility model relates to a frock of joint bearing inner circle sphere processing ring belongs to machining technical field.
Background
Because joint bearing inner race is spherical, unable accurate positioning when processing the ring on the sphere, traditional processing mode is: the tool is fixed on a grinding machine, and two surfaces of the inner ring are separately processed, and the method has the following defects: 1. inaccurate positioning: because the two surfaces are processed separately, the positioning points need to be repeatedly measured and searched in positioning, so that different positioning surfaces with errors exist in the same set of products; 2. the operation is complex: a positioning center needs to be found during each processing, and the same set of products need to be fed up and down twice; 3. the precision is poor: the machined circular ring and the inner ring are not concentric due to secondary clamping; 4. the efficiency is low: a set of products needs 20-30min when being processed on a traditional grinder, wherein the processing time is only 5-8min, the rest time is wasted on loading and unloading and searching a processing center, and the processing efficiency is low.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem that exists among the prior art, the utility model provides a frock of joint bearing inner circle sphere processing ring can automatic positioning, and convenient operation practices thrift process time.
The utility model discloses a realize above-mentioned technical purpose through following technical scheme.
A tool for machining a circular ring on the spherical surface of an inner ring of a joint bearing comprises a positioning seat, a positioning shaft and the inner ring, wherein a mounting hole of the positioning seat is in clearance fit with the positioning shaft, and after the shaft diameter of the positioning shaft is in clearance fit with the inner diameter of the inner ring, the top of the inner ring is fixed on the positioning seat through a screw.
In the above scheme, the screw penetrates through the end cap to fix the inner ring on the positioning seat.
In the above scheme, the matching position of the positioning seat and the positioning shaft is added with the fixing glue.
In the scheme, the matching shaft of the positioning seat is in clearance fit with the positioning hole of the grinding machine.
The utility model has the advantages that:
the utility model discloses the cooperation axle of well positioning seat and the locating hole cooperation of grinding machine for the positioning seat is coaxial with grinding machine work piece axle, the mounting hole and the positioning shaft interference fit of positioning seat, and the inner circle internal diameter is fixed the inner circle on the positioning seat by the screw with positioning shaft diameter clearance fit back, and the inner circle is coaxial with the positioning seat, and the inner circle is also coaxial with the grinding machine like this, guarantees the precision of location, need not to look for the positioning center, and is easy and simple to handle, improves machining efficiency, and is lower to operative employee's basic skill requirement.

Detailed Description
The technical solution of the present invention will be further described with reference to the following specific embodiments, but the scope of the present invention is not limited thereto.
As shown in fig. 1 and 2, a tool for processing a ring on a spherical surface of an inner ring of a joint bearing comprises a positioning seat 1, a positioning shaft 2, an end cap 3, a screw 4 and an inner ring 5, wherein an installation hole of the positioning seat 1 is in interference fit with the positioning shaft 2, fixing glue can be added at the matching part during assembly, and the positioning shaft 2 is ensured not to have transmission in the processing process; the positioning shaft 2 needs to ensure the vertical difference of the shaft surface when being manufactured, the vertical difference is less than or equal to 0.01mm, and the vertical difference between the positioning surface (the contact surface between the inner ring 5 and the positioning seat) of the positioning seat 1 and the inner ring 5 after being clamped is ensured; after the shaft diameter of the positioning shaft 2 is in clearance fit with the inner diameter of the inner ring 5, the top of the inner ring 5 penetrates through the end cap 3 by a screw 4 to fix the inner ring 5 on the positioning seat 1.
When the tool is used, firstly, the matching shaft of the positioning seat 1 is in clearance fit with the positioning hole of the grinding machine, the coaxiality of the positioning seat 1 and the workpiece shaft of the grinding machine is ensured, and the inner ring 5 is coaxial with the grinding machine because the inner ring 5 is coaxial with the positioning seat 1; on this basis, the positioning seat 1 also needs to meet the following installation requirements: the mounting hole is vertical to the mounting surface, the mounting surface is horizontal to the axis of the positioning shaft 1, and the distance from the mounting surface to the center of the matching shaft is half of the height of the inner ring 5; the tool is arranged on a grinding machine after being assembled, and can be machined only by adjusting the contact position of the grinding wheel and the circular ring; the inner ring 5 of the tool can be replaced only by loosening the screw 4. The utility model discloses the frock utilizes current bearing processing equipment, still guaranteed the machining precision when can install fast, automatic positioning, go up unloading more convenient, and the lower operative employee of basic skill can all process, practices thrift the cost of labor.
The above mentioned embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all equivalent modifications or changes made according to the present invention should be included in the protection scope of the claims.
