Description

Technical Field

[0001] The utility model relates to the technical field of tool cooling, in particular to a tool cooling device for a machining center. Background Art

[0002] Tools have various uses in the process of mechanical processing, such as cutting, drilling, boring, reaming, etc. A large amount of heat will be generated during the use of tools. High temperature will affect the cutting performance and service life of tools. Therefore, it is necessary to cool down the tools. Currently, the common way to cool down the tools is to spray cooling water on the surface of the tools. However, the way of spraying cooling water is prone to spraying and splashing, and it is impossible to fully cover and cool tools with different processing lengths during the processing. Therefore, the technical personnel in this field provide a tool cooling device for a machining center to solve the problems raised in the above background art. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a tool cooling device for a machining center, including a machining center seat. A machining tool head is fixedly installed in the middle of the lower end of the machining center seat. Driving devices are symmetrically arranged at the left and right ends of the machining center seat, and a cooling device is fixedly installed on the outer side surface of the driving device;

[0004] The driving device includes a socket, a threaded rod, a dovetail groove, a sliding female seat, a dovetail block, a return spring and a device seat. The sockets are symmetrically installed up and down in the middle of the left and right side end faces of the machining center seat. A threaded rod is arranged between the sockets. The threaded rod is externally connected to a driving motor for rotation. Dovetail grooves are symmetrically opened before and after at the left and right side end faces of the machining center seat. A device seat is arranged on the outer side of the threaded rod. A sliding female seat is fixedly installed on the upper part of the inner side of the device seat. The sliding female seat is in tooth engagement with the threaded rod. Dovetail blocks are symmetrically fixedly installed on the front and back of the inner side end face of the top sliding female seat. The dovetail blocks are arranged in the dovetail grooves.

[0005] Preferably: A return spring is fixedly installed at the lower end of the dovetail block. By using the elastic deformation ability of the return spring, it is ensured that the dovetail block drives the cooling device on the device seat to slide stably, so as to ensure that the coolant sprayed by the cooling device can continuously and stably spray on the machining tool head.

[0006] Preferably: The cooling device includes a positioning plate, a conduit, a hose, a rotating slot, a supporting column, a nozzle and a guide plate. A plurality of positioning plates are fixedly installed on the inner side end face of the device seat, and a plurality of conduits are fixedly inserted through the positioning plates.

[0007] Preferably: A hose is connected to the lower end of the conduit.

[0008] Preferably: Rotating slots are opened on the front and back of the bottom of the device seat, and a supporting column with damping rotation is arranged between the rotating slots.

[0009] Preferably: a plurality of nozzles are installed at equal intervals at the lower end of the support column, the nozzles are docked with the hoses, and a guide plate is fixedly installed at the bottom of the outer side of the device seat, so that an external water pump pressurizes the liquid into the conduit, passes it to the nozzles through the hose, and cooperates with the arc-shaped guide surface of the guide plate to guide the flow to cool the processing tool head.

[0010] Technical effects and advantages of the utility model:

[0011] 1. When the utility model is used, the threaded rod is driven to rotate by an external driving motor, the sliding nut is engaged with the threaded rod, and the dovetail block slides within the dovetail groove in a limited manner, so that the sliding nut drives the cooling device to move downward, so that the cooling device can always be kept at the same horizontal line for different processing cutter heads, thereby ensuring the cooling effect.

[0012] 2. When the utility model is used, the support column is rotated so that the nozzle is directed toward the processing cutter head to ensure that the coolant can completely spray the surface of the processing cutter head. Then, an external water pump is used to pressurize the liquid into the conduit, and the liquid is supplied to the nozzle through a hose. The arc-shaped guide surface of the guide plate is used to guide the flow to cool the processing cutter head to prevent the spray coolant from splashing, thereby resulting in poor cooling effect.

A reset spring 36 is fixedly installed at the lower end of the dovetail block 35. The elastic deformation capacity of the reset spring 36 is used to ensure that the dovetail block 35 drives the cooling device 4 on the device seat 37 to slide stably, thereby ensuring that the coolant sprayed by the cooling device 4 can be continuously and stably sprayed on the processing tool head 2;

[0022] The cooling device 4 includes a positioning plate 41, a conduit 42, a hose 43, a rotating slot 44, a support column 45, a nozzle 46 and a guide plate 47. A plurality of positioning plates 41 are fixedly installed on the inner end surface of the device seat 37, and a plurality of conduits 42 are inserted and fixed on the positioning plate 41.
