Description

Stable water supply shank

This creation relates to a gripping tool, in particular a shank that stabilizes water supply.

The conventional arbor is attached to the front end of the cutter, and the rear end of the arbor is coupled to the main shaft of the processing machine, and the cutter is driven by the spindle to perform the cutting operation, so as to avoid the heat of the tool during processing. Deformation or hot embrittlement, so the processor usually has a coolant tube for spraying the coolant directly outside the tool for cooling.

Because the conventional external spray cooling method can only concentrate the cooling tool, the part of the arbor is still subject to the heat conduction of the tool and continues to heat up. Under long-term use, the arbor may be deformed by heat, and the cooling effect is poor, which is improved. Necessary.

In order to solve the problem that the conventional cutter bar is cooled by external spray, and the cooling is easily concentrated on the cutter portion, which causes the cutter bar to heat up and deform, and the cooling effect is poor, the main purpose of the present invention is to provide a cutter bar capable of stably supplying water. The system is capable of introducing a coolant into the inside of the arbor to cool the coolant inside the arbor, and the coolant can be concentrated to the cutter by the water guiding groove and the water blocking ring, and then guided out through the cutter to make the cooling effect more Good promotion.

The technical means used in this creation is to provide a tool holder for stable water supply, including: a shank body is formed on the outer periphery of the front end to form a set of joints, and a through hole having a front and a rear through shape and a step shape is formed inside the shank body, and a cylindrical shape is formed at a front end of the through hole The sleeve is provided with at least one water guiding groove on the peripheral wall of the set space, and the at least one water guiding groove extends from the sleeve space to the front edge of the through hole; a nut is a hollow cylinder And a sleeve is coupled to the shank of the shank body, the nut is slightly protruded from the front end of the shank body; a water blocking ring is disposed inside the nut and is fixedly coupled to the arbor The front end of the body is covered by the at least one water guiding groove, and the water blocking ring has a central hole, and the diameter of the central hole is slightly larger than the diameter of the casing space.

The foregoing cutter bar for stabilizing the water supply, wherein the cutter bar system is provided with a plurality of water guiding grooves, and the water guiding channels are arranged along the set space to form a surrounding shape.

The foregoing sturdy water supply arbor, wherein the plurality of water guiding grooves have a semicircular cross section.

The foregoing knife bar for stabilizing the water supply, wherein the water blocking ring is provided with a water retaining ring on the outer circumference of the water blocking ring.

This creation utilizes the provided stable water supply shank, and the improved effect is that the creation has a water guiding groove inside the arbor, and can introduce coolant into the water guiding groove in the arbor, and is installed inside the arbor The tool is cooled, and the water blocking ring is used to stop the coolant inside the shank. In addition to avoiding the overflow of the coolant, the coolant can flow out from the gap formed between the water blocking ring and the tool. The cooling liquid concentrates on the tool to cool, and at the same time improves the overall cooling effect, which is quite practical and convenient.

In order to be able to understand in detail the technical features and practical functions of the present invention, and can be implemented in accordance with the contents of the specification, and further illustrated in the preferred embodiment as illustrated in the following figure, the present invention is a stable water supply knife. The preferred embodiment of the present invention includes a shank body 10, a nut 20, a water blocking ring 30 and a cutter 40, wherein: as shown in FIGS. 1 and 2, The shank body 10 has a circular hollow shape at the front end, and a hollow conical rod body is formed at the rear end. The outer periphery of the shank body 10 is a set portion 11 at the front end of the shank body 10, and the outer periphery of the shank body 10 is A spindle mounting portion 12 is a ring-shaped flange portion 13 between the sleeve portion 11 and the spindle mounting portion 12, as shown in FIGS. 2 and 3, in the tool holder body 10 The inner portion has a through hole 14 which is formed in a front and a rear shape and is stepped, and a cylindrical outer sleeve space 141 is formed at the front end of the through hole 14 and surrounds the through hole forming the sleeve space 141. The 14-week wall system is provided with a plurality of water guiding grooves 142, and the water guiding grooves 142 are arranged to form a surrounding shape, and the plural Cross-section and the guide gutter 142 by the semicircular edge after Yan Shen and respectively sleeved space 141 to the edge 141 before the looping space.

As shown in FIG. 3 and FIG. 4 , the nut 20 is a hollow cylinder and is sleeved and fitted to the sleeve portion 11 of the cutter body 10 and abuts against the front side of the flange portion 13 . It is slightly protruding from the front end of the shank body 10.

As shown in FIG. 3 and FIG. 4 , the water blocking ring 30 is disposed inside the nut 20 and is screwed to the front end of the shank body 10 and covers the plurality of water guiding grooves 142 . The water ring 30 has a center hole 31, the diameter of the center hole 31 is slightly larger than the diameter of the sleeve space 141, and the water blocking ring A water blocking ring 32 is sleeved at a portion of the outer circumference of the 30 that is in contact with the nut 20.

The cutter 40 is inserted into the central hole 31 of the water blocking ring 30 and penetrates into the sleeve space 141 of the cutter body 10 so that the cutter 40 can abut against the side wall of the sleeve space 141.

In the preferred embodiment of the present invention, as shown in FIG. 4 and FIG. 5, the coolant is introduced from the through hole 14 of the shank body 10, and the coolant flows from the water guiding grooves 142 to the cutter 40, because the coolant receives the resistance. The water ring 30 blocks, so that the coolant flows out along the formed gap between the cutter 40 and the water blocking ring 30, and can flow down with the front end of the cutter 40, and with the water retaining ring 32 of the water blocking ring 30. Blocking, the coolant can be prevented from overflowing toward the gap between the water blocking ring 30 and the nut 20, so that the cooling liquid can be simultaneously cooled inside the cutter body 10 and the cutter 40 to Achieve better cooling.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way. Anyone having ordinary knowledge in the technical field may use the present invention without departing from the technical features of the present invention. Equivalent embodiments of the local changes or modifications made by the technical content disclosed herein are still within the scope of the features of the present invention.
