Abstract
The utility model relates to a shaping cutter for processing a bearing body, which comprises a cutter bar, a first cutter head and a second cutter head, wherein the first cutter head and the second cutter head are arranged on the cutter bar; the highest position of the first cutter head is higher than that of the second cutter head. Through the cooperation of first tool bit and second tool bit, saved recess B's process time, improved bearing body machining efficiency, the bearing body yield reaches 100%.
Description
Technical Field
The utility model relates to a bearing body processing technology field especially relates to bearing body processing is with shaping sword.
Background
In the processing bearing body in-process, as shown in fig. 1, it is 52.15mm to require the distance of recess B to terminal surface C to be the specified value, present processing mode is generally to process terminal surface C through the tool bit earlier, then recess B is processed to the rethread grooving cutter, when processing recess B, in order to guarantee that recess B is the specified value to terminal surface C's size, the tool setting needs to be calibrated, when the tool setting is calibrated, because the hole is darker can not be visualized, the tool tip is extremely easy to fish tail terminal surface C, and recess B is hardly guaranteed to the specified value to terminal surface C's size, exceed error range easily, lead to the rejection rate to reach 15%, reduce production efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to prior art's not enough, provide bearing body processing and use shaping sword.
The utility model is realized by the following technical proposal, provides a forming cutter for processing a bearing body, which comprises a cutter bar, a first cutter head and a second cutter head which are arranged on the cutter bar, wherein the vertical distance from a first cutter head processing surface to a second cutter head processing surface is equal to the distance from a groove B to an end surface C; the highest position of the first cutter head is higher than that of the second cutter head.
Preferably, the cutter bar is provided with a first mounting groove and a second mounting groove respectively.
Preferably, the mounting portion of the first cutter head is disposed in the first mounting groove and is press-fastened by the first pressing plate, and the mounting portion of the second cutter head is disposed in the second mounting groove and is press-fastened by the second pressing plate.
Preferably, the first pressing plate and the second pressing plate are respectively fixed with the cutter bar through fixing bolts.
After the end face C is machined, the machining face of the second tool bit is just in contact with the end face C, when the groove B is machined, the machining can be conducted by feeding along the direction A, and the vertical distance from the machining face of the first tool bit to the machining face of the second tool bit is equal to the vertical distance from the groove B to the end face C, so that when the groove B is machined, tool setting and position measurement are not needed, the machining time is saved, the working efficiency is improved, and the yield reaches 100%.
The utility model has the advantages that:
the utility model discloses a cooperation of first tool bit and second tool bit has saved recess B's process time, has improved bearing body machining efficiency, and bearing body yield reaches 100%.

Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in fig. 2, 3 and 4, the utility model discloses a cutter arbor 1 and install first tool bit 2 and second tool bit 3 on cutter arbor 1, first tool bit 2 is for being used for processing the grooving sword of 4 recess B of the bearing body, and second tool bit 3 is used for processing 4 terminal surfaces C of the bearing body. The perpendicular distance d from the machined surface of the first tool bit 2 to the machined surface of the second tool bit 3 is equal to the distance from the groove B to the end surface C, the distance from the groove B to the end surface C is required to be 52.15mm, and therefore the perpendicular distance from the machined surface of the first tool bit 2 to the machined surface of the second tool bit 3 is set to be 52.15 mm.
Set up first mounting groove 5 and second mounting groove 6 respectively on cutter arbor 1, the installation department of first tool bit 2 is arranged in first mounting groove 5 and is compressed tightly fixedly through first pressure strip 7, and the installation department of second tool bit 3 is arranged in second mounting groove 6 and is compressed tightly fixedly through second pressure strip 8, first pressure strip 7 and second pressure strip 8 are fixed with cutter arbor 1 through fixing bolt respectively. The highest position of the first cutting head 2 is higher than the highest position of the second cutting head 3.
The method for processing the bearing body 4 by using the forming cutter comprises the following steps: (1) extending the cutter bar 1, the first cutter head 2 and the second cutter head 3 into the bearing body 4, enabling the second cutter head 3 to contact an end face C of the bearing body 4 and carrying out finish machining on the end face C, as shown in FIG. 3;
(2) after the end face C is machined, the groove B is machined by feeding in the direction a, as shown in fig. 4.
After the end face C is machined, the machining face of the second tool bit 3 just contacts with the end face C, when a groove B is machined, the groove B is machined by feeding along the direction A, and the vertical distance from the machining face of the first tool bit 2 to the machining face of the second tool bit 3 is equal to the vertical distance from the groove B to the end face C, so that when the groove B is machined, tool setting and position measurement are not needed, the machining time is saved, the machining efficiency of the bearing body 4 is improved, and the yield of the bearing body 4 reaches 100%.
Of course, the above description is not limited to the above examples, and technical features of the present invention that are not described in the present application may be implemented by or using the prior art, and are not described herein again; the above embodiments and drawings are only used for illustrating the technical solutions of the present invention and are not intended to limit the present invention, and the present invention has been described in detail with reference to the preferred embodiments, and those skilled in the art should understand that changes, modifications, additions or substitutions made by those skilled in the art within the spirit of the present invention should also belong to the protection scope of the claims of the present invention.
