Description

Technical Field

[0001] This utility model relates to the field of tungsten carbide end mill technology, specifically a tungsten carbide end mill with anti-vibration function for grooving. Background Technology

[0002] Tungsten carbide is a sintered composite material containing at least one metal carbide, also known as cemented carbide. It has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. Tungsten carbide is also one of the good materials for making end mills, and end mills made of tungsten carbide can be used for a longer time.

[0003] An existing patent (publication number CN221817445U) discloses a tungsten steel end mill with anti-vibration function for grooving. It is connected to a plug rod at the bottom of the end mill head, and a shock-absorbing pad is provided at the connection between the plug rod and the connecting rod. The gap between the end mill head and the plug rod is reduced by the shock-absorbing pad and the one-to-one correspondence between the plug rod and the connecting rod, thereby increasing the anti-vibration function of the end mill during use.

[0004] However, there are some problems with the use of existing milling cutters: 1. The length of the current milling cutter is a fixed size. When grooving to different depths is required, milling cutters of different lengths can only be replaced, which affects the efficiency of processing; 2. Existing tungsten carbide milling cutters achieve the anti-vibration effect through vibration damping pads when connected and fixed. However, the vibration damping pads are made of soft material and will still generate amplitude when affected by vibration, so they cannot achieve an effective anti-vibration effect. Utility Model Content

[0005] The purpose of this invention is to provide a tungsten carbide end mill with anti-vibration function for grooving, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including a mounting base, a telescopic component disposed on the upper end of the mounting base, a reinforcing component disposed on the outer side of the upper end of the telescopic component, and a blade body mounted on the upper side through the reinforcing component;

[0007] The telescopic assembly includes a telescopic groove formed in the mounting base, a rod is movably installed in the telescopic groove, a slot is formed on the side wall of the rod, and a slot is formed on the side wall of the telescopic groove corresponding to the slot, and a plug rod that cooperates with the slot is installed in the slot.

[0008] The reinforcement component includes a groove at the lower end of the blade body and an inner groove at the upper end of the insert rod. A first bevel gear is provided on the inner wall of the lower left end of the inner groove. A knob is connected to the left end of the first bevel gear. A second bevel gear is provided on the lower side wall of the partition plate of the inner groove, which cooperates with the first bevel gear.

[0009] As a further improvement of this utility model: the slotted sidewall is provided with a side groove, and the insert rod sidewall is provided with a side plate that cooperates with the side groove.

[0010] As a further improvement of this utility model: a hydraulic rod is installed on the side wall of the side plate, and a spring is fitted onto the hydraulic rod.

[0011] As a further embodiment of this utility model: a connecting rod is installed inside the upper end of the inner groove, a conical gear ring is fitted on the outer wall of the connecting rod, and a third conical gear is provided on the upper side wall of the inner groove to cooperate with the conical gear.

[0012] As a further embodiment of this utility model: a sliding groove is provided on the outer right side of the inner groove, a screw is connected in the sliding groove, a retaining plate is fitted on the outer wall of the screw, and a retaining groove is provided on the right side of the groove to cooperate with the retaining plate.

[0013] As a further improvement of this utility model: a limiting groove is provided on the upper side wall of the slide groove, and a limiting plate that cooperates with the limiting groove is provided on the upper side wall of the card plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the machining length of the milling cutter needs to be adjusted, the insert rod is pulled outward to move it from inside to outside the slot. At the same time, the insert rod moves in and out of the slot, causing the upper and lower side plates to move within the side slot. This compresses the hydraulic rod and spring, generating potential energy. When the insert rod is completely disengaged from the slot, the insert rod is pulled upward to move it upward within the telescopic groove. The extended length is adjusted so that the slot at the corresponding height position is aligned with the slot. The tension on the insert rod is released, and the spring releases potential energy to push the side plate inward, causing the insert rod to insert into the aligned slot. This completes the adjustment of the tool body's working length.

[0016] When the tool body needs to be installed, the lower end of the tool body is inserted into the upper end of the insert rod through the groove. Turning the knob drives the first bevel gear connected to it to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the connecting rod connected to it to rotate, which drives the outer bevel gear ring to rotate, which in turn drives multiple sets of third bevel gears to rotate synchronously, which in turn drives the screw connected to them to rotate. With the limiting plate embedded in the limiting groove, the engagement drives the locking plate to move from inside and outside the slide groove and insert into the aligned locking slot. Through multiple sets of locking components, the tool body is firmly positioned, avoiding shaking and vibration, and improving the anti-vibration effect. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example 1

[0023] like Figures 1 to 4As shown, this embodiment provides a tungsten carbide end mill with anti-vibration function for grooving, including a mounting base 1, a telescopic assembly disposed on the upper end of the mounting base 1, a reinforcing assembly disposed on the outer side of the upper end of the telescopic assembly, and a cutter body 3 mounted on the upper side through the reinforcing assembly. The telescopic assembly includes a telescopic groove 201 formed in the mounting base 1, a retaining rod 202 movably installed in the telescopic groove 201, a slot 203 formed on the side wall of the retaining rod 202, and a slot 204 corresponding to the slot 203 formed on the side wall of the telescopic groove 201. A insert rod 205 that cooperates with the slot 203 is installed in the slot 204, so that the slot 203 at the corresponding height position is aligned with the slot 204. When the tension on the insert rod 205 is released, the spring 209 releases potential energy to push the side plate 207 inward, causing the insert rod 205 to insert into the aligned slot 203. Within 3, the length of the blade body 3 can be adjusted. The reinforcement component includes a groove 401 at the lower end of the blade body 3 and an inner groove 402 inside the upper end of the insert rod 202. A first bevel gear 403 is provided on the lower left inner wall of the inner groove 402. A knob 404 is connected to the left end of the first bevel gear 403. A second bevel gear 405 is provided on the lower side wall of the partition plate of the inner groove 402, which cooperates with the first bevel gear 403. The meshing drives multiple sets of third bevel gears 408 to rotate synchronously, which drives the screw 410 connected to them to rotate. Under the limitation of the limiting plate 414 embedded in the limiting groove 413, the meshing drives the locking plate 411 to move in and out of the sliding groove 409 and insert into the aligned locking groove 412. The multiple locking components achieve a firm positioning of the blade body 3, avoid shaking and vibration, and improve the anti-vibration effect. Example 2

[0024] In addition to all the technical features in Embodiment 1, this embodiment also includes: a side groove 206 is provided on the side wall of the slot 204, and a side plate 207 is provided on the side wall of the insertion rod 205 to cooperate with the side groove 206, thereby driving the upper and lower side plates 207 to move within the side groove 206, making the disassembly and assembly process more stable.

[0025] Furthermore, a hydraulic rod 208 is installed on the side wall of the side plate 207. The hydraulic rod 208 is fitted with a spring 209. The spring 209 releases potential energy to push the side plate 207 inward, causing the insertion rod 205 to be inserted into the aligned slot 203, thereby completing the adjustment of the working length of the blade body 3.

[0026] Furthermore, a connecting rod 406 is installed inside the upper end of the inner groove 402, and a conical gear ring 407 is fitted on the outer wall of the connecting rod 406. A third conical gear 408 is provided on the upper side wall of the inner groove 402, which cooperates with the conical gear 407. When the conical gear ring 407 rotates, it meshes and drives multiple sets of third conical gears 408 to rotate synchronously, so that multiple sets are fixed synchronously.

[0027] Furthermore, a sliding groove 409 is provided on the outer right side of the inner groove 402, and a screw 410 is connected in the sliding groove 409. A retaining plate 411 is fitted on the outer wall of the screw 410. A retaining groove 412 is provided on the right side of the groove 401 to cooperate with the retaining plate 411. The retaining plate 411 moves in and out of the sliding groove 409 and is inserted into the aligned retaining groove 412. The tool body 3 is firmly positioned by multiple sets of retaining components.

[0028] Furthermore, a limiting groove 413 is provided on the upper side wall of the slide groove 409, and a limiting plate 414 is provided on the upper side wall of the clamping plate 411 to cooperate with the limiting groove 413. Under the limiting of the limiting plate 414 embedded in the limiting groove 413, the clamping plate 411 is driven to move from inside and outside the slide groove 409 and insert into the aligned clamping groove 412. The tool body 3 is firmly positioned by multiple sets of clamping components to avoid shaking and vibration.

[0029] Working principle: When the machining length of the milling cutter needs to be adjusted, pull the insert rod 205 outward to move it in and out of the slot 203. At the same time, the insert rod 205 moves in and out of the slot 204, causing the upper and lower side plates 207 to move within the side groove 206. This compresses the hydraulic rod 208 and spring 209, generating potential energy. When the insert rod 205 is completely disengaged from the slot 203, pull the insert rod 202 upward to move it upward within the telescopic groove 201, adjusting the extended length. After adjustment, the slot 203 at the corresponding height position is aligned with the slot 204. Release the tension on the insert rod 205, and the spring 209 releases potential energy, pushing the side plate 207 inward, causing the insert rod 205 to insert into the aligned slot 203, thus completing the use of the cutter body 3. For length adjustment, when the blade body 3 needs to be installed, the lower end of the blade body 3 is inserted into the upper end of the insert rod 202 through the groove 401. Turning the knob 404 drives the first bevel gear 403 connected to it to rotate, which in turn drives the second bevel gear 405 to rotate, which in turn drives the connecting rod 406 connected to it to rotate, which in turn drives the outer bevel gear ring 407 to rotate, which in turn drives multiple sets of third bevel gears 408 to rotate synchronously, which in turn drives the screw 410 connected to it to rotate. Under the limitation of the limiting plate 414 embedded in the limiting groove 413, the engagement drives the locking plate 411 to move in and out of the slide groove 409 and insert into the aligned locking groove 412. Through multiple sets of locking components, the blade body 3 is firmly positioned, avoiding shaking and vibration, and improving the anti-vibration effect.
