Description

Technical Field

[0001] This utility model relates to an internal cooling tap, specifically an internal cooling tap with automatic coolant recovery, belonging to the technical field of internal cooling taps. Background Technology

[0002] Internal cooling taps are advanced thread-cutting tools widely used in the machining field. The cutting edge of an internal cooling tap typically undergoes special grinding and processing, resulting in higher hardness, wear resistance, and sharpness. The geometry of the cutting edge is optimized for better material cutting while reducing cutting forces and heat generation.

[0003] In existing technologies, such as the internally cooled tap disclosed in CN218575183U, coolant can be injected into the inlet hole for cooling. After injection, the coolant can be discharged through the drain hole for cooling. When machining a threaded hole of a certain depth, the first nut and the second nut are loosened first. After loosening, the screw is moved up and down. When moving, the bottom end of the slider can be aligned with the appropriate scale line. After alignment, the first nut and the second nut are tightened to complete the adjustment. During machining, the spring of the buffer component gives the baffle a certain buffering effect. The threaded hole of a certain depth can be machined by blocking the baffle for use. When it is necessary to block debris, the second round hole of the baffle can be aligned with the stud and inserted. Then, the third nut is rotated to fix the baffle. After fixing, the baffle can block the machining debris and avoid the problem of debris flying around and being difficult to recycle.

[0004] However, in implementing the relevant technology, the following problems were found in the internal cooling tap of the above design: In the prior art, the coolant can be circulated to achieve the effects of heat dissipation and lubrication through the cooperation of components such as the liquid inlet hole. However, during use, the coolant is continuously supplied and discharged, resulting in a large amount of coolant flowing out and causing waste. In view of this, an internal cooling tap with automatic coolant recovery is provided to overcome the above defects. Utility Model Content

[0005] This invention provides an internal cooling tap with automatic coolant recovery to solve the technical problem of waste caused by the continuous supply and discharge of coolant.

[0006] The present invention achieves the above objectives through the following technical solution: an internal cooling tap with automatic coolant recovery, comprising a taper rod, a taper head fixedly installed at the bottom end of the taper rod, and a limiting groove formed on the outer wall of the taper rod, and a circulation mechanism provided on one side of the limiting groove on the outer wall of the taper rod;

[0007] The circulation mechanism includes a sleeve shell, which is sleeved on one side of the limiting groove on the outer wall of the cone rod. A locking block is fixedly installed inside the sleeve shell at the position corresponding to the limiting groove. A storage battery is fixedly installed at the bottom end of the sleeve shell, and a cooling plate is embedded in the outer wall of the sleeve shell.

[0008] As a further improvement of this utility model: a micro pump is embedded in the lower part of the inner wall of the sleeve, and a water supply hole is opened on one side of the inner wall of the sleeve.

[0009] As a further improvement of this utility model: a flow hole is provided on the outer wall of the cone rod corresponding to the water supply hole, and a flow channel is provided inside the cone rod, with a drain channel provided at the bottom end of the flow channel.

[0010] As a further improvement of this utility model: a fastening ring is provided above the outer wall of the cone rod and the cooling plate on the outer wall of the shell is provided with a feeding mechanism.

[0011] As a further embodiment of this utility model: the feeding mechanism includes a rotating slot, which is located above the cooling fins on the outer wall of the housing, and the inner wall of the rotating slot has an inlet.

[0012] As a further embodiment of this utility model: a locking block is rotatably connected inside the rotating slot, and a rotating shell is fixedly installed on the outer wall of the locking block. An insertion hole is opened on the outer wall of the locking block, and a connecting pipe extends out from the outer wall of the rotating shell.

[0013] As a further improvement of this utility model: a sleeve is fitted on the outer wall of the connecting pipe, and a feeding pipe extends out from the front end of the sleeve.

[0014] The beneficial effects of this utility model are: through the cooperation of the limiting groove and the locking block, the sleeve is fitted onto the outer wall of the cone rod, and the battery provides power to the cooling plate and the micro pump, so that the coolant can form a circulation through the water supply hole, the flow hole and the flow channel, and the heated coolant can be automatically recovered, cooled and flowed out to form a circulation. A small amount of coolant is discharged through the drain channel to lubricate the drilling position, avoiding the situation of large amount of discharge causing waste. Thus, while circulating and cooling the coolant, it avoids excessive waste.

[0015] The sleeve allows for the connection and disassembly of the connecting pipe and the supply pipe of the external coolant supply equipment, thereby allowing coolant to be introduced into the rotating shell. The rotating shell is rotatably connected to the rotating slot of the sleeve shell by a locking block. This prevents the external coolant supply equipment from being affected and causing a limit during the rotation of the cone rod. When the inlet and the through hole are aligned, coolant can be allowed to enter, preventing the amount of coolant directly introduced from exceeding the discharge capacity of the drain channel, which could lead to excessive coolant or excessive pressure inside the sleeve shell.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] like Figures 1 to 6As shown, an internal cooling tap with automatic coolant recovery includes a taper 1, a taper head 2 fixedly installed at the bottom end of the taper 1, a limiting groove 3 formed on the outer wall of the taper 1, and a circulation mechanism 4 provided on one side of the limiting groove 3 on the outer wall of the taper 1; the circulation mechanism 4 includes a sleeve 401, which is sleeved on one side of the limiting groove 3 on the outer wall of the taper 1, a locking block 402 fixedly installed inside the sleeve 401 at a position corresponding to the limiting groove 3, a battery 403 fixedly installed at the bottom end of the sleeve 401, a cooling chip 404 embedded in the outer wall of the sleeve 401, a micro pump 405 embedded in the lower part of the inner wall of the sleeve 401, and a water supply hole 406 formed on one side of the inner wall of the sleeve 401. The outer wall of the taper 1 is connected to the water supply hole 406. A flow hole 407 is provided at the position, and a flow channel 408 is provided inside the cone rod 1. A drain channel 409 is provided at the bottom end of the flow channel 408. Through the cooperation of the limiting groove 3 and the locking block 402, the sleeve 401 is fitted onto the outer wall of the cone rod 1, and the battery 403 provides power to the cooling plate 404 and the micro pump 405. This allows the coolant to circulate through the water supply hole 406, the flow hole 407 and the flow channel 408. The heated coolant is automatically recovered, cooled and then flows out to form a circulation. A small amount of coolant is discharged through the drain channel 409 to lubricate the drilling position, avoiding the waste caused by large amounts of discharge. Thus, while circulating and cooling the coolant, excessive waste is avoided. Example 2

[0025] In addition to all the technical features in Embodiment 1, this embodiment also includes: a fastening ring 5 is fitted above the outer wall of the cone rod 1 and the outer wall of the shell 401; a feeding mechanism 6 is provided on one side of the cooling chip 404 on the outer wall of the shell 401; the feeding mechanism 6 includes a rotating slot 601, which is located above the cooling chip 404 on the outer wall of the shell 401; an inlet 602 is provided on the inner wall of the rotating slot 601; a locking block 604 is rotatably connected inside the rotating slot 601; a rotating shell 603 is fixedly installed on the outer wall of the locking block 604; an insertion hole 605 is provided on the outer wall of the locking block 604; and a connecting pipe 60 protrudes from the outer wall of the rotating shell 603. 6. A sleeve 7 is fitted on the outer wall of the connecting pipe 606, and a feed pipe 8 extends out from the front end of the sleeve 7. The sleeve 7 allows the connecting pipe 606 and the feed pipe 8 of the external coolant supply equipment to be disassembled and assembled, thereby inputting coolant into the rotating shell 603. The rotating shell 603 is rotatably connected to the rotating slot 601 of the sleeve shell 401 through the locking block 604. This can prevent the external coolant supply equipment from being limited during the rotation of the cone rod 1. When the inlet 602 and the through hole 605 correspond, coolant can be allowed to enter, avoiding the direct introduction of coolant volume exceeding the discharge volume of the drain channel 409, which would result in excessive coolant or excessive pressure inside the sleeve shell 401.

[0026] Working principle: The locking block 402, which fixes the sleeve 401, passes through the limiting groove 3 into the cone rod 1 and is fastened from above by the fastening ring 5, which is threaded to the cone rod 1, thus fixing the sleeve 401. At the same time, the water supply hole 406 and the output end of the micro pump 405 correspond to the flow hole 407 opened on the outer wall of the cone rod 1. The cooling plate 404 reduces the temperature of the coolant inside the sleeve 401. Under the output of the micro pump 405, the coolant can enter the flow channel 408 and circulate back to the sleeve 401, so that the coolant that has lost heat can flow back to cool down and then cool again, achieving an automatic recovery effect. At the same time, the drain channel 409 is smaller than the flow channel 408, allowing a small amount of coolant to flow out through the through hole at the bottom of the cone head 2, which has a lubricating effect and prevents a large amount of coolant from flowing out. To prevent waste caused by coolant loss, the rechargeable battery 403 provides power to the cooling chip 404 and the micro pump 405, and avoids the cable connection method affecting the drilling of the cone 2. The sleeve 401 is rotatably connected to the locking block 604 fixed to the rotating shell 603 through the rotating slot 601, which allows the connecting pipe 606 and the feed pipe 8 to be connected by the sleeve 7 through threaded connection, and to the external coolant supply equipment. This ensures that the rotation of the sleeve 401 does not affect the stability of the rotating shell 603, so that when the feed port 602 and the through hole 605 are aligned, the supplied coolant can be replenished into the sleeve 401, avoiding direct flow replenishment, which would exceed the discharge of the drain channel 409, resulting in excessive coolant or excessive pressure inside the sleeve 401.
