Description

Technical Field

[0001] The utility model relates to the technical field of machine tool components, in particular to a central water outlet spindle. Background Art

[0002] With the development of technology, the market has put forward higher requirements for the precision and quality of workpieces and processing efficiency. The center water discharge of machine tools has been widely used in the market, but many multi-spindle special equipment have not yet realized this function, especially the special equipment of the drilling series. The special equipment of the drilling series is widely used in the automotive, new energy and other industries. In order to solve the existing industry pain points, a multi-spindle center water discharge special equipment has been developed.

[0003] The existing patent application (CN203110540U) discloses a metal machining center with water outlet from the spindle center, including a metal machining center body, the metal machining center body is provided with a head, the head includes a rotating spindle for machining workpieces, the rotating spindle is a hollow structure, the metal machining center body also includes a cooling and chip flushing mechanism, the cooling and chip flushing mechanism includes a liquid supply mechanism and a rotary joint, the liquid outlet of the liquid supply mechanism is connected to the liquid inlet of the rotary joint, and the rotary joint is connected to the rotating spindle. The patent has the following shortcomings: the water outlet mode of the spindle center water outlet mechanism is single, the uniformity of the water outlet is not ideal, and the cooling effect is poor; the water outlet direction of the spindle center water outlet mechanism is difficult to adjust, and the water outlet component is difficult to replace and maintain, and it is inconvenient to use.

[0004] Therefore, a distribution mechanism is needed to distribute cutting fluid to different central water outlet spindles of a multi-spindle box. Summary of the invention

[0005] The utility model aims to solve the problems of single water outlet mode, unsatisfactory water outlet uniformity and poor cooling effect of the spindle center water outlet mechanism, and provides a spindle with different center water outlets which distributes cutting fluid to a multi-axis box through a distribution mechanism.

[0006] The utility model provides a central water outlet spindle, comprising a multi-axis box, a water inlet, a distributor, a spindle, a tool clamp and a tool. The spindle is installed on the multi-axis box and the debugging is completed. The distributor is installed on the multi-axis box and cooperates with the spindle. The circular cavities at the lower parts of both ends of the distributor are sealed with sealing rings to form a sealed cavity. The water inlet pipe joint is installed on the distributor, the tool clamp is installed on the spindle, and the tool is installed on the tool clamp.

[0007] The central water outlet main shaft described in the utility model is preferably configured such that the distributor is in a circular ring shape.

[0008] The central water outlet main shaft described in the utility model is preferably provided with a plurality of circular holes for installing the main shaft on the distributor.

[0009] In the central water outlet main shaft described in the utility model, as a preferred embodiment, the cross section of the sealing ring is smaller than the cross section of the circular cavity.

[0010] When in use, the cutting fluid enters the water distributor from the water inlet, then enters the inside of the spindle through the water inlet on the side of the spindle, flows through the cutter body from inside the spindle into the tool, and comes out from the water outlet of the tool, realizing the central water outlet function.

[0011] The utility model effectively solves the problems that the water outlet mode of the main shaft center water outlet mechanism is single, the uniformity of the water outlet is not ideal, and the cooling effect is poor. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Example 1

[0018] like Figure 1 As shown, a central water outlet spindle, a multi-axis box 1, a water inlet 2, a distributor 3, a spindle 4, a tool clamp 5, and a tool 6. The spindle 4 is installed on the multi-axis box 1 and the debugging is completed. The distributor 3 is installed on the multi-axis box 1 and cooperates with the spindle 4. The circular cavities at the lower parts of both ends are sealed with sealing rings 7 to form a sealed cavity. The water inlet 2 pipe joint is installed on the distributor 3, the tool clamp 5 is installed on the spindle 4, and the tool 6 is installed on the tool clamp 5.

[0019] The cross section of the sealing ring 7 is smaller than the cross section of the circular cavity.

[0020] like Figure 2 As shown, the distributor 3 is in the shape of a ring.

[0021] The distributor 3 is provided with four circular holes for mounting the main shaft.

[0022] During use of this embodiment, the cutting fluid enters the water distributor from the water inlet, then enters the interior of the spindle through the water inlet on the side of the spindle, flows through the tool body from the inside of the spindle into the tool, and comes out from the water outlet of the tool, realizing the central water outlet function.

[0023] The above description is only illustrative rather than restrictive of the present invention. Those skilled in the art will understand that any modification, change or equivalent that can be made without departing from the spirit and scope defined by the claims will fall within the protection scope of the present invention.
