Description
Technical Field
The utility model belongs to ball platform class parts machining field relates to a ball platform class parts centre bore processing frock.
Background
After the ball table type parts are roughly machined and formed, the outer surfaces of the parts are spherical, so that inconvenience is brought to the alignment and machining of a central hole in the next procedure. Traditional ball platform class part centre bore processing clamping mode does: the outer spherical surface of the part is clamped by a soft claw of a lathe, the end surface is leveled and compressed, and then a central hole is machined, so that the part is easy to rotate in the clamping process, and the machining precision is reduced; and the contact area between the spherical surface of the table part and the soft claw of the lathe is small, when the end surface is pressed, the part is easy to slightly rotate, the part needs to be clamped again, the surface quality is influenced, and each table part needs to be processed once by alignment, so that the production efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model designs a center hole processing tool for parts such as a table, which plays a role in quickly aligning, positioning and clamping the center in the process of processing the center hole of the parts such as the table; meanwhile, the clamping is firmer, the stress is more uniform, and the influence of slight rotation of the table parts on the size precision is avoided.
The technical scheme of the utility model is that:
the utility model provides a ball platform class part centre bore processing frock, includes: the device comprises a front end positioning shaft 1, a rear end positioning shaft 2, a positioning shaft sleeve 3, an adjustable gasket 4 and a fastening screw 5;
the internal thread of the front end positioning shaft 1 is matched and connected with the external thread on one side of the rear end positioning shaft 2; the internal thread of the positioning shaft sleeve 3 is matched and connected with the external thread on the other side of the rear end positioning shaft 2, and the machined table parts are fastened and fixed through the rear end positioning shaft 2 and the inner cavity of the female die of the positioning shaft sleeve 3, so that the table parts are automatically centered and positioned; the clearance between the end face of the table part and the end face of the female die of the rear end positioning shaft 2 is eliminated by adopting an adjustable gasket 4, so that the end face of the table part is attached to the end face of the female die of the rear end positioning shaft 2; three fastening screws 5 are used for fixing the table type part.
Furthermore, the rear end positioning shaft 2 and the positioning shaft sleeve 3 are of different specifications and matched models, and are used for machining center holes of table parts with different diameters.
Further, the specifications of the adjustable gasket 4 and the rear end positioning shaft 2 are matched with each other.
The utility model can effectively avoid the processing error caused by uneven clamping stress and slight rotation of parts, and improve the production efficiency; the ball table parts with different specifications can be efficiently and conveniently processed by replacing the positioning shaft and the positioning shaft sleeve with different specifications.

Detailed Description
The following detailed description is made with reference to the accompanying drawings.
As shown in the figure, the center hole machining tool for the table parts comprises a front end positioning shaft 1, a rear end positioning shaft 2, a positioning shaft sleeve 3, an adjustable gasket 4 and a fastening screw 5. The internal thread of the front end positioning shaft 1 is matched and screwed with the external thread on one side of the rear end positioning shaft 2, so that the end faces of the front end positioning shaft 1 and the rear end positioning shaft 2 are tightly attached; the internal thread of the positioning shaft sleeve 3 is matched and screwed with the external thread on the other side of the second rear end positioning shaft 2 to provide clamping force for the processed table, and the rear end positioning shaft 2 and the positioning shaft sleeve 3 are used for tightly fixing and positioning the table parts to be processed through the cavity of the female die, so that the table parts are automatically positioned at the center; the adjustable gasket 4 is used for eliminating the gap between the end face of the table part and the end face of the female die of the rear end positioning shaft 2, so that the joint degree between the end face of the table part and the end face of the female die of the rear end positioning shaft 2 is higher, and the machining precision of the part is improved; three fastening screws 5 are used for fixing the table parts, so that the size processing precision is improved.
The specific operation steps are as follows:
(1) Mounting the table parts 6 into the female die end face of the rear end positioning shaft 2 and the female die inner cavity of the positioning shaft sleeve 3, screwing the rear end positioning shaft 2 and the positioning shaft sleeve 3 through threaded connection, measuring the gap between the end face of the table parts 6 and the end face of the second rear end positioning shaft 2, and marking;
(2) Disassembling the clamp, selecting an adjustable gasket 4 with proper specification to be installed between the end face of the table part 6 and the end face of the female die of the rear end positioning shaft 2, and screwing the positioning shaft sleeve 3 on the rear end positioning shaft 2;
(3) Screwing the assembled component onto the front end positioning shaft 1 to ensure that the end surfaces of the front end positioning shaft 1 and the rear end positioning shaft 2 are tightly attached;
(4) The fastening screws 5 are uniformly adjusted and tightened.
(5) The jig is attached to a lathe, and after the machining work is completed, the jig is detached from the lathe.
