Description

Technical Field

[0001] This invention relates to the field of tool locking technology, and more particularly to a tool locking structure. Background Technology

[0002] Cutting tools are tools used for cutting and machining in mechanical manufacturing. The vast majority of cutting tools are machine-made, but some are hand-operated. Since cutting tools used in mechanical manufacturing are primarily for cutting metal materials, the term "cutting tool" is generally understood as a metal cutting tool. Tools used for cutting wood are called woodworking tools. There is also a special category of cutting tools used in geological exploration, well drilling, and mining; these are called mining tools.

[0003] Traditional cutting tool designs often integrate the cutting head and shank into a single unit, a non-removable structure that limits usability. Most cutting tools on the market today use a threaded connection, separating the cutting head from the shank and enhancing maintainability. However, while this design prioritizes a secure connection, it also presents disassembly challenges: because installation often requires tight tightening to prevent loosening, lubricating oil is difficult to add externally and flow into the spiral grooves. This results in significant friction making it difficult to easily disassemble the cutting head when replacement is needed, thus impacting the convenience and efficiency of head replacement.

[0004] Therefore, a tool locking structure is needed to solve the above problems. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] In view of the problems of the aforementioned tool locking structure, this invention is proposed.

[0007] Therefore, the purpose of this invention is to provide a tool locking structure that solves the problem that "due to the need for tight tightening during installation to prevent loosening, it is difficult for lubricating oil to be added externally and flow into the spiral groove, resulting in difficulty in easy disassembly due to large friction when the tool head needs to be replaced, thus affecting the convenience and efficiency of tool head replacement."

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a tool locking structure, comprising:

An air intake pipe is fixedly connected to one side of each of the two straight cylinders, and an air inlet pipe is fixedly connected to the opposite side of each of the two straight cylinders. A thin tube is fixedly connected to the other end of each air inlet pipe, and an air blowing pipe is fixedly connected to the other end of each thin tube. The air blowing mechanism also includes two oil supply pipes. One end of each oil supply pipe is connected to a second arc-shaped groove, and multiple nozzles are fixedly connected at equal intervals on the side wall of each oil supply pipe.

[0012] In a preferred embodiment of the tool locking structure of the present invention, the two air supply pipes, the two liquid outlet pipes and the two oil supply pipes are all fixedly embedded in the tool holder, and the plurality of nozzles are respectively arranged in the plurality of oil outlet holes. The plurality of oil outlet holes are arranged in two rows, and the two rows of oil outlet holes are staggered according to their height.

[0013] In a preferred embodiment of the tool locking structure of the present invention, one end of the push rod passes through the cylinder and the inner conical groove and is slidably connected to the inner wall of the cylinder and the tool holder, and the top plate is slidably connected to the inner wall of the cavity.

[0015] In a preferred embodiment of the tool locking structure described in this invention, an air inlet check valve is fixedly installed in each of the two air intake pipes, an air outlet check valve is fixedly installed in each of the two air intake pipes, each air intake pipe and air outlet pipe is fixedly embedded in the tool holder, and the diameter of the two thin tubes is smaller than the diameter of the air inlet pipe and the air outlet pipe.

[0016] In a preferred embodiment of the tool locking structure described in this invention, the vertical rod is slidably connected to the inner wall of the cylinder, and the two ends of the return spring are respectively fixedly connected to the upper end of the slide plate and the inner wall of the cylinder.

[0017] As a preferred embodiment of the tool locking structure of the present invention, the clamping assembly includes a ring and a plurality of elastic arc strips, the ring being fixedly connected to the inner wall of the inner conical groove, and one end of each of the plurality of elastic arc strips being fixedly connected to the ring.

[0018] In a preferred embodiment of the tool locking structure described in this invention, when the disc moves upward to its highest point, it abuts against the inner wall of the plurality of elastic arc-shaped strips, and the diameter of the disc is smaller than the diameter of the upper end face of the inner conical groove and the diameter of the upper end face of the arc groove.

[0019] As a preferred embodiment of the tool locking structure of the present invention, a threaded sleeve is fixedly sleeved on the tool head, a locking nut matching the threaded sleeve is slidably sleeved on the mounting sleeve, a limit block is fixedly connected to the lower side wall of the mounting sleeve, and the locking nut engages with the threaded sleeve when it moves downward.

[0021] The beneficial effects of this invention are:

[0022] 1. During installation, when the disc is pressed against the groove, it will push the disc to move upward and stretch the return spring. The disc will squeeze the elastic arc strip, causing multiple elastic arc strips to expand outward and press against the arc groove, making the connection between the cutter head and the cutter bar tighter and preventing loosening during processing.

[0023] 2. During installation, the disc and vertical rod drive the sliding plate upward and squeeze the corrugated air bag. The gas in the corrugated air bag is delivered to the surface of the lubricating oil in the oil tank through the air supply pipe. The air pressure squeezes the lubricating oil downward and makes it flow into the No. 1 arc groove and the No. 2 arc groove through the liquid outlet pipe. At this time, a small amount of lubricating oil will flow into the spiral groove through the oil supply pipe and the nozzle.

[0024] 3. During disassembly, the disc returns to its original position under the force of the return spring. The disc and the vertical rod drive the sliding plate downwards, which in turn drives the connecting rod downwards via the sliding plate, the top rod, and the top plate. The connecting rod then drives the piston plate downwards, allowing the air inside the straight cylinder to pass through the air inlet pipe and be blown out through the air blowing pipe. The air mixes with the lubricating oil and is blown into the spiral groove through the oil delivery pipe and the nozzle, increasing the contact area between the lubricating oil and the spiral groove, reducing friction, and making disassembly easier. This, in turn, improves the convenience and efficiency of cutting head replacement. Attached Figure Description

[0043] Example 1

[0044] Reference Figures 1-12 As one embodiment of the present invention, a tool locking structure is provided, comprising:

[0045] The tool body 100 includes a tool shank 101 and a tool head 102. A tapered mounting head 105 is fixedly mounted on one end of the tool head 102. The tapered mounting head 105 has mounting threads on its sidewall and an arc-shaped groove 105a inside. A recess 105b is formed within the arc-shaped groove 105a. A mounting sleeve 106 is fixedly connected to the lower end of the tool shank 101. An inner tapered groove 106a is formed at the lower end of the mounting sleeve 106. The inner tapered groove 106a has a 3° inner taper surface that mates with the tapered mounting head 105. A spiral groove is formed on the inner tapered surface of the tool holder 106a. Multiple oil outlet holes 106b are formed at equal intervals on the inner tapered surface of the inner tapered groove 106a. A clamping assembly 107 is fixedly installed in the inner tapered groove 106a. Two intermediate cavities 108 and a cavity are symmetrically formed inside the tool holder 101. Each intermediate cavity 108 has a first arc groove 108a and a second arc groove 108b. When the tapered mounting head 105 is screwed into the inner tapered groove 106a to a certain depth, the mounting thread will lock with the inner tapered surface. At this time, the cutting force of the tool will increase the locking tendency to prevent the tool from loosening.

[0046] The extrusion mechanism 200 includes a cylinder 201 and two oil storage tanks 208. Each oil storage tank 208 is fixedly installed on the side wall of the cutter bar 101. The cylinder 201 is fixedly connected in the inner conical groove 106a. A slide plate 202 is slidably connected to the inner wall of the cylinder 201. A vertical rod 203 is fixedly connected to the lower end of the slide plate 202. The lower end of the vertical rod 203 passes through the cylinder 201 and is fixedly connected to a disc 204. A return spring 205 is sleeved on the vertical rod 203. Two corrugated air bags 206 are symmetrically fixedly connected to the upper end of the slide plate 202. Air supply pipes 207 and liquid outlet pipes 209 are fixedly connected to opposite sides of the two oil storage tanks 208. The other end of each air supply pipe 207 is connected to the inside of the corrugated air bag 206. The other end of each liquid outlet pipe 209 is connected to the first arc groove 108a.

[0047] The air blowing mechanism 300 includes a push rod 301 and two straight cylinders 302. Each straight cylinder 302 is fixedly connected to the inner wall of the cavity. One end of the push rod 301 is fixedly connected to the slide plate 202, and the other end of the push rod 301 is fixedly connected to a top plate 303. Two connecting rods 304 are symmetrically fixedly connected to the lower end of the top plate 303. The lower end of each connecting rod 304 passes through the upper end of the straight cylinder 302 and is fixedly connected to a piston plate 305. One side of each of the two straight cylinders 302... The air intake pipe 310 is fixedly connected. The two straight cylinders 302 are fixedly connected to the opposite sides of each other by an air inlet pipe 306. The other end of each air inlet pipe 306 is fixedly connected to a thin tube 307. The other end of each thin tube 307 is fixedly connected to an air blowing pipe 308. The air blowing mechanism 300 also includes two oil supply pipes 309. One end of each oil supply pipe 309 is connected to the second arc groove 108b. Multiple nozzles 309a are fixedly connected at equal intervals on the side wall of each oil supply pipe 309.

[0048] During installation, when the disc 204 is pressed against the groove 105b, it will push the disc 204 upward and stretch the return spring 205. The disc 204 will compress the elastic arc strip 107b, causing multiple elastic arc strips 107b to expand outward and press against the arc groove 105a, making the connection between the cutter head 102 and the cutter bar 101 tighter and preventing loosening during processing. At the same time, the disc 204 and the vertical rod 203 will drive the slide plate 202 upward and compress the corrugated air bag 206. The gas in the corrugated air bag 206 will be transported through the air supply pipe 207 to the surface of the lubricating oil in the oil tank 208. The air pressure will then compress the lubricating oil downward and make it flow into the first arc groove 108a and the second arc groove 108b through the liquid outlet pipe 209. At this time, a small amount of lubricating oil will flow into the spiral groove through the oil supply pipe 309 and the nozzle 309a.

[0049] Furthermore, during disassembly, the disc 204 returns to its original position under the elastic force of the return spring 205. The disc 204 and the vertical rod 203 drive the slide plate 202 to move downwards. The slide plate 202, the push rod 301, and the top plate 303 drive the connecting rod 304 to move downwards. The connecting rod 304 drives the piston plate 305 to move downwards, so that the air in the straight cylinder 302 is blown out through the air inlet pipe 306 and the air blowing pipe 308. The air mixes with the lubricating oil and is blown into the spiral groove through the oil supply pipe 309 and the nozzle 309a, increasing the contact area between the lubricating oil and the spiral groove, reducing friction, and making disassembly easier. This improves the convenience and efficiency of replacing the cutter head 102.

[0050] Among them, two air supply pipes 207, two liquid outlet pipes 209 and two oil supply pipes 309 are all fixedly embedded in the cutter bar 101. Multiple nozzles 309a are respectively set in multiple oil outlet holes 106b. The multiple oil outlet holes 106b are arranged in two rows, and the two rows of oil outlet holes 106b are staggered according to their height. The staggered arrangement of oil outlet holes 106b can make the lubricating oil flow more evenly and increase the contact area between the lubricating oil and the spiral groove.

[0051] One end of the push rod 301 passes through the cylinder 201 and the inner conical groove 106a and is slidably connected to the inner wall of the cylinder 201 and the knife rod 101. The top plate 303 is slidably connected to the inner wall of the cavity. Both connecting rods 304 are slidably connected to the inner wall of the straight cylinder 302. Both piston plates 305 are slidably connected to the inner wall of the straight cylinder 302. Multiple nozzles 309a are connected to the oil supply pipe 309. The piston plates 305 are moved by the arrangement of the push rod 301, the top plate 303 and the connecting rods 304.

[0052] Each of the two suction pipes 310 is fixedly equipped with an air inlet check valve, and each of the two air inlet pipes 306 is fixedly equipped with an air outlet check valve. Each suction pipe 310 and air inlet pipe 306 is fixedly embedded in the cutter bar 101. The diameters of the two thin tubes 307 are smaller than the diameters of the air inlet pipe 306 and the air blowing pipe 308. The thin tubes 307 can compress the passing air and blow it out at high speed through the air blowing pipe 308.

[0053] The vertical rod 203 is slidably connected to the inner wall of the cylinder 201, and the two ends of the return spring 205 are fixedly connected to the upper end of the slide plate 202 and the inner wall of the cylinder 201, respectively. The return spring 205 drives the disc 204 to return to its original position.

[0054] The clamping assembly 107 includes a ring 107a and multiple elastic arc-shaped strips 107b. The ring 107a is fixedly connected to the inner wall of the inner conical groove 106a. One end of each of the multiple elastic arc-shaped strips 107b is fixedly connected to the ring 107a. When the disc 204 moves upward to the highest point, it abuts against the inner sidewall of the multiple elastic arc-shaped strips 107b. The diameter of the disc 204 is smaller than the diameter of the upper end face of the inner conical groove 106a and the diameter of the upper end face of the arc-shaped groove 105a. By pressing the elastic arc-shaped strips 107b by the disc 204, the multiple elastic arc-shaped strips 107b expand outward and abut against the arc-shaped groove 105a.

[0055] The cutter head 102 is fixedly fitted with a threaded sleeve 103, and a locking nut 104 matching the threaded sleeve 103 is slidably fitted on the mounting sleeve 106. A limit block is fixedly connected to the lower side wall of the mounting sleeve 106. When the locking nut 104 moves downward, it engages with the threaded sleeve 103. The locking nut 104 and the threaded sleeve 103 can further prevent the cutter head 102 from loosening.

[0056] The upper ends of the two oil reservoirs 208 are fixedly connected with oil injection pipes, and the upper end of each oil injection pipe is connected with a sealing cap, so that lubricating oil can be easily replenished through the oil injection pipes.

[0057] Working principle: During installation, the tapered mounting head 105 is pressed against the inner tapered groove 106a and rotated, causing the tapered mounting head 105 to screw into the inner tapered groove 106a. When the disc 204 is pressed against the groove 105b, it pushes the disc 204 upward and stretches the return spring 205. The disc 204 compresses the elastic arc strips 107b, causing multiple elastic arc strips 107b to expand outward and press against the arc groove 105a, making the connection between the cutter head 102 and the cutter shank 101 tighter and preventing loosening during processing; and, During this process, the disc 204 and the vertical rod 203 drive the slide plate 202 to move upward and squeeze the corrugated air bag 206. The gas in the corrugated air bag 206 is transported to the surface of the lubricating oil in the oil tank 208 through the air supply pipe 207, which increases the pressure above the surface of the lubricating oil. The air pressure squeezes the lubricating oil downward and makes it flow into the first arc groove 108a through the liquid outlet pipe 209, and then continues to flow into the second arc groove 108b. At this time, a small amount of lubricating oil will flow into the spiral groove through the oil supply pipe 309 and the nozzle 309a.

[0058] Furthermore, during disassembly, the conical mounting head 105 is slowly separated from the inner conical groove 106a by reverse rotation. At this time, the disc 204 returns to its original position under the elastic force of the return spring 205. The disc 204 and the vertical rod 203 drive the sliding plate 202 to move downward. The sliding plate 202, the top rod 301 and the top plate 303 drive the connecting rod 304 to move downward. The connecting rod 304 drives the piston plate 305 to move downward, so that the air in the straight cylinder 302 is blown out through the air inlet pipe 306 and the air blowing pipe 308. The air mixes with the lubricating oil and is blown into the spiral groove through the oil supply pipe 309 and the nozzle 309a, increasing the contact area between the lubricating oil and the spiral groove, reducing friction, and making disassembly easier. This improves the convenience and efficiency of replacing the cutter head 102. The contents not described in detail in this description are prior art known to those skilled in the art.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
