Abstract

The utility model discloses a rotating shaft connecting device of a crystal hot-fix rhinestone die, which comprises a rotating shaft body, a left end socket and a right end socket, wherein the left end socket and the right end socket are turned at two ends of the rotating shaft body through a turning machine and are both provided with fixing grooves; four circular arc-shaped grooves with screw holes are formed in each fixing groove; a cooling hole with a threaded inner wall is formed in the rotating shaft body; the diameter of the rotating shaft body is larger than those of the left end socket and the right end socket. The rotating shaft connecting device of the crystal hot-fix rhinestone die has the benefits that the fixing grooves are formed in the left end socket and the right socket of the rotating shaft body, the circular arc-shaped grooves with the screw holes are formed in the fixing grooves, and the rotating shaft body can be firmly connected onto production equipment through the fixing grooves and the screw holes; the cooling hole is formed in the rotating shaft body so as to achieve a good radiating effect; the quality is excellent; the service life is long.

Description

A kind of crystal rhinestone mold rotation shaft coupling device

Technical field

The utility model relates to a kind of crystal rhinestone mold, particularly a kind of crystal rhinestone mold rotation shaft coupling device.

Background technology

Crystal hot-drilling die is the main tool of producing Crystal ornaments, hot-drilling die is mainly by the work of rhinestone rotating shaft driven rotary, in existing crystal hot-drilling rotating shaft, be connected insecure with production equipment, long-term use easily become flexible, and on producing, reduced production efficiency, once it is high to damage maintenance cost, cause the quality of product unstable, and original technology is all manually water to be poured into crystal hot-drilling rotating shaft surface to carry out coolingly, because now labour is rare, increased greatly cost input.

Utility model content

For addressing the above problem, the purpose of this utility model is to provide and is a kind ofly connected firmly, the crystal rhinestone mold rotation shaft coupling device of good quality, long service life.

For achieving the above object, the technical solution of the utility model is:

A kind of crystal rhinestone mold rotation shaft coupling device, comprise rotating shaft body, left end head, right-hand member head, described rotating shaft body two ends go out left end head and right-hand member head by lathe car, on left end head and right-hand member head, all have holddown groove, arrange four with the arc groove of screw in holddown groove.

As preferably, described rotating shaft body is provided with the Cooling Holes that inwall is screw thread.

As preferably, described rotating shaft body diameter is greater than left end head and right-hand member head.

The beneficial effects of the utility model are to have holddown groove on the left end head of rotating shaft body and right-hand member head, in holddown groove, be provided with the arc groove of screw, rotating shaft body can firmly be connected on production equipment by holddown groove, screw, in rotating shaft body, be provided with Cooling Holes good heat dissipation effect, good quality, long service life.
