Description

Technical Field

[0001] The present invention relates to the technical field of deep hole machining, and particularly relates to an ultrasonic deep hole machining device. Background Art

[0002] During ultrasonic deep hole machining, the cutting tool vibrates at an ultrasonic frequency, making the cutting process between the cutting tool and the workpiece intermittent; when the cutting tool vibrates away from the workpiece, the cutting force will decrease sharply. Compared with the traditional continuous cutting method, the average cutting force can be reduced a lot, which helps to reduce tool wear and better cope with the working conditions of long-distance cutting in deep hole machining.

[0003] Currently, in the prior art, during the ultrasonic machining of deep holes, usually the ultrasonic drill is directly inserted into the deepest part of the workpiece to start machining. Although ultrasonic machining can reduce tool wear to a certain extent, when using this operation, the ultrasonic drill will be subjected to a large cutting force and friction force at the bottom of the deep hole for a long time, and it will cause chips at the bottom of the deep hole to be not easy to discharge. Therefore, the ultrasonic drill will also be affected by the additional force caused by poor chip removal, resulting in faster and more serious wear of the part of the ultrasonic drill at the bottom of the deep hole, shortening the overall service life of the ultrasonic drill, increasing the tool replacement frequency and machining cost. In view of this, the present invention is specifically proposed. Summary of the Invention

[0013] Further, a second spring is sleeved on the outer wall of the push rod. The second spring is arranged between the third piston and the inner wall of the cylinder. A water suction pipe and a drain pipe are further provided on the outer wall of the cylinder. A support pipe communicated with the drain pipe is provided on the outer wall of the water tank.

A cover plate is further provided on the bracket.

[0015] Compared with the prior art, the present invention provides an ultrasonic deep hole processing device, which has the following beneficial effects: 1. This ultrasonic deep-hole processing equipment can make the distance that the ultrasonic drill bit moves each time deeper than the previous time. By working in this reciprocating manner, the operation of deep-hole processing can be slowly completed. Moreover, through frequent deep-hole processing, the debris in the deep hole can be effectively discharged to avoid accumulation. Additionally, in this application, as the ultrasonic drill bit gradually processes from shallow to deep, it can prevent a certain part of the ultrasonic drill bit from being excessively worn due to long-term exposure to high-intensity cutting; this extends its service life.

[0016] 2. In this ultrasonic deep-hole processing equipment, when the rack extends, the trapezoidal block on the rack will touch the block. At this time, the inclined surface on the trapezoidal block will cooperate with the inclined surface on the block, causing the trapezoidal block to push the block to rotate. At this time, the turntable will not rotate. When the rack retracts after the work is completed, the trapezoidal block will touch the block again. At this time, it is the flat surface of the trapezoidal block and the block that are in contact. Under the continuous action of the trapezoidal block, the block will be driven to move, thereby causing the turntable to rotate. When the turntable rotates, it can drive the lead screw to rotate through the rotating shaft, so that the distance that the ultrasonic drill bit penetrates each time will gradually become deeper, and the deep hole will be processed deeper successively, achieving a protective effect on the ultrasonic drill bit.

[0017] 3. This ultrasonic deep-hole processing equipment can spray coolant or cutting fluid through the support pipe and the spray pipe. The spray pipe is oriented towards the processing frame, enabling the coolant to be sprayed on the part where the ultrasonic drill bit contacts the workpiece, achieving a cooling effect. Secondly, through the above-mentioned ultrasonic deep-hole processing operation with gradually increasing depth, it is relatively easier to utilize the flushing effect of the coolant and the chip removal assistance generated by ultrasonic vibration, facilitating the timely discharge of chips out of the hole under the action of the coolant; and at the beginning of processing, the depth of the processed hole is relatively shallow, the chip discharge path at the relatively shallow position is short, and it is not easy to encounter the dilemma that a large amount of chips accumulate at the bottom of the deep hole and are difficult to discharge, effectively avoiding the problem of chip blockage, ensuring the smooth progress of the processing process, and also contributing to maintaining good machining surface quality.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0022] Example 1: Refer to Figures 1-9, An ultrasonic deep-hole processing device, including a support frame 1 and a support table 101 placed on the support frame 1, further including a bracket 2 fixedly arranged on the support table 101, and a groove 201 is provided on the bracket 2; a threaded rod 202 is slidably arranged on the bracket 2, and the bottom of the threaded rod 202 is connected with an ultrasonic base 203, and an ultrasonic drill 204 is installed on the ultrasonic base 203; a gear 207 is rotatably connected in the groove 201, and the threaded rod 202 is threadedly connected at the center of the gear 207; a cylinder body 3 is also fixedly arranged in the groove 201, a cylinder 303 is slidably connected in the cylinder body 3, and a rack 304 meshing with the gear 207 is arranged at the output end of the cylinder 303; the inner wall of the groove 201 is fixedly provided with a conveying cylinder 5, and the conveying cylinder 5 is communicated with the cylinder body 3; a processing frame 102 is arranged on the support table 101.

[0023] In this embodiment, during use, first place the workpiece to be processed by ultrasonic deep-hole processing in the processing frame 102 for fixing, and then start the cylinder 303 to drive the rack 304 at its output end to reciprocate, so that the rack 304 reciprocally drives the engaged gear 207 to rotate. When the rack 304 extends and meshes with the gear 207, the gear 207 will be threadedly connected with the threaded rod 202, so that the threaded rod 202 moves downward, driving the ultrasonic base 203 and the ultrasonic drill 204 to move downward for drilling operations. When the rack 304 resets, it will drive the gear 207 to move in the opposite direction, so that the threaded rod 202 drives the ultrasonic base 203 and the ultrasonic drill 204 to move out of the drilled hole, and at the same time, a part of the debris can be discharged to avoid debris accumulation. When the rack 304 resets and drives the threaded rod 202 to reset, a part of the gas will be discharged from the conveying cylinder 5 and enter the cylinder body 3, thereby pushing the first piston 301 to move, driving the cylinder 303 a certain distance. At this time, when the cylinder 303 drives the rack 304 to extend, since in the initial state, the rack 304 moves towards the end close to the gear 207, and the distance of each movement of the rack 304 is fixed, therefore, the rack 304 will drive the gear 207 to rotate a certain distance more, so that the moving distance of the threaded rod 202 is slightly longer. At this time, the drilling operation of the ultrasonic base 203 and the ultrasonic drill 204 will be deeper. By repeating this operation, the moving distance of the ultrasonic drill 204 can be made deeper than the previous time each time, thus slowly completing the deep-hole processing operation. And frequent deep-hole processing can effectively discharge the debris in the deep hole to avoid accumulation. Moreover, in this application, as the ultrasonic drill 204 gradually processes from shallow to deep, the situation that a certain part of the ultrasonic drill 204 is subjected to high-intensity cutting for a long time and is over-worn can be avoided; the service life is extended.

[0024] In this application, an ultrasonic generator is built into the ultrasonic base 203, which enables the ultrasonic drill 204 to perform ultrasonic deep hole machining operations. It can be specifically implemented by using the ultrasonic generator in the prior art.

[0025] Embodiment 2: Refer to Figures 1-8 , an ultrasonic deep hole machining device, includes a support frame 1 and a support table 101 placed on the support frame 1. It also includes a bracket 2 fixedly arranged on the support table 101. There is a groove 201 on the bracket 2; a threaded rod 202 is slidably arranged on the bracket 2, and the bottom of the threaded rod 202 is connected to an ultrasonic base 203, and an ultrasonic drill 204 is installed on the ultrasonic base 203; a gear 207 is rotatably connected in the groove 201, and the threaded rod 202 is threadedly connected to the center of the gear 207; a cylinder body 3 is also fixedly arranged in the groove 201, a cylinder 303 is slidably connected in the cylinder body 3, and a rack 304 meshing with the gear 207 is arranged at the output end of the cylinder 303; a conveying cylinder 5 is fixedly arranged on the inner wall of the groove 201, and the conveying cylinder 5 is communicated with the cylinder body 3; a processing frame 102 is arranged on the support table 101.

[0026] A first piston 301 is slidably connected in the cylinder body 3, the cylinder 303 is fixedly connected to the first piston 301, and a first spring 302 is arranged between the first piston 301 and the inner wall of the cylinder body 3.

[0027] In this embodiment, after the gas enters the cylinder body 3 through the conveying cylinder 5, it will push the first piston 301 to move, so that the first piston 301 drives the whole cylinder 3 to move, so that the meshing distance between the rack 304 and the gear 207 becomes longer.

[0028] A rotating shaft 4 is rotatably connected in the groove 201. A turntable 402 is arranged on the rotating shaft 4. A clamping block 404 is arranged on the outer wall of the turntable 402, and a trapezoidal block 305 matched with the clamping block 404 is arranged on the outer wall of the rack 304.

[0029] A plurality of mounting seats 403 are circumferentially distributed on the outer wall of the turntable 402. Each mounting seat 403 is rotatably connected with a clamping block 404, and a torsion spring 406 is also arranged between the clamping block 404 and the mounting seat 403.

[0030] Both the clamping block 404 and the trapezoidal block 305 are provided with mutually matching inclined surfaces and flat surfaces. A baffle 405 is fixedly connected to one side of the mounting seat 403 close to the inclined surface of the clamping block 404.

[0031] In this embodiment, refer to Figure 7, when the rack 304 extends, the trapezoidal block 305 on the rack 304 will touch the latch 404. First, the inclined surface on the trapezoidal block 305 will cooperate with the inclined surface on the latch 404, causing the trapezoidal block 305 to push the latch 404 to rotate. At this time, the turntable 402 will not rotate. When the rack 304 retracts after the work is completed, the trapezoidal block 305 will touch the latch 404 again. At this time, the plane on the trapezoidal block 305 abuts against the plane on the latch 404. Due to the provision of the baffle 405, the latch 404 will not rotate towards the side close to the baffle 405. Therefore, under the continuous action of the trapezoidal block 305, the latch 404 will be driven to move, thereby causing the turntable 402 to rotate. When the turntable 402 rotates, it can drive the lead screw 401 to rotate through the rotating shaft 4 for subsequent operations.

[0032] Referring to Figure 6 , a lead screw 401 is fixedly connected to the top of the rotating shaft 4. A threaded block 503 is threadedly connected to the lead screw 401. A thin rod 502 is provided at the top of the threaded block 503. A second piston 501 is provided at the top of the thin rod 502. The second piston 501 is slidably connected in the delivery cylinder 5.

[0033] A connecting pipe 505 is connected between the delivery cylinder 5 and the cylinder body 3. A support plate 504 is fixedly connected in the delivery cylinder 5. The top of the lead screw 401 passes through the delivery cylinder 5 and is rotatably connected to the support plate 504. The thin rod 502 is slidably connected to the delivery cylinder 5 and the support plate 504.

[0034] In this embodiment, when the rack 304 retracts and resets to drive the turntable 402 to rotate, it will drive the rotating shaft 4 to drive the lead screw 401 to rotate, so that the lead screw 401 is threadedly connected to the threaded block 503. Under the limitation of the thin rod 502, the threaded block 503 can be moved. At the same time, under the action of the thin rod 502, the second piston 501 is pushed to move upward in the delivery cylinder 5, thereby squeezing the gas in the delivery cylinder 5, and injecting it into the cylinder body 3 through the connecting pipe 505, thereby pushing the first piston 301 to move, and then driving the cylinder 303 to move a certain distance, so that the meshing distance between the rack 304 and the gear 207 increases. Repeating this way, it can ensure that each time the meshing distance between the rack 304 and the gear 207 increases by a part, so that the depth of penetration of the ultrasonic drill 204 will gradually become deeper each time, and the deep hole is processed deeper and deeper, achieving a protective effect on the ultrasonic drill 204.

[0035] Embodiment Three: Referring to Figures 1-8, an ultrasonic deep-hole processing device, comprising a support frame 1 and a support table 101 placed on the support frame 1, and further comprising a bracket 2 fixedly arranged on the support table 101, with a groove 201 provided on the bracket 2; a threaded rod 202 is slidably arranged on the bracket 2, and the bottom of the threaded rod 202 is connected to an ultrasonic base 203, and an ultrasonic drill bit 204 is installed on the ultrasonic base 203; a gear 207 is rotatably connected in the groove 201, and the threaded rod 202 is threadedly connected to the center of the gear 207; a cylinder body 3 is also fixedly arranged in the groove 201, a cylinder 303 is slidably connected in the cylinder body 3, and a rack 304 meshing with the gear 207 is provided at the output end of the cylinder 303; the inner wall of the groove 201 is fixedly provided with a conveying cylinder 5, and the conveying cylinder 5 is communicated with the cylinder body 3; a processing frame 102 is arranged on the support table 101.

[0036] Referring to Figure 8 and Figure 9 , a pressing plate 209 is fixedly connected to the outer wall of the threaded rod 202, a water tank 6 is fixedly connected to the inner wall of the bracket 2, a cylinder 601 is arranged in the water tank 6, a third piston 602 is slidably connected in the cylinder 601, a push rod 604 is provided at the top of the third piston 602, the top of the push rod 604 passes through the water tank 6 and is connected to a push plate 605, and the push plate 605 cooperates with the pressing plate 209.

[0037] Referring to Figure 9 , a second spring 603 is sleeved on the outer wall of the push rod 604, the second spring 603 is arranged between the third piston 602 and the inner wall of the cylinder 601, a water suction pipe 607 and a drain pipe 608 are further provided on the outer wall of the cylinder 601, and a support pipe 609 communicated with the drain pipe 608 is provided on the outer wall of the water tank 6, and a spray pipe 606 is provided on the support pipe 609.

[0038] In this embodiment, before use, coolant or cutting fluid is injected into the water tank 6 first. The water tank 6 is provided with a water injection port at the top and a drain port on the side, which facilitates water injection and drainage. During the process of the threaded rod 202 rotating and driving the ultrasonic base 203 and the ultrasonic drill 204 to move downward, the pressing plate 209 can be synchronously driven to move, so that the pressing plate 209 presses the push plate 605, and then presses the third piston 602 through the push rod 604, so that it moves into the cylinder 601, and squeezes the coolant or cutting fluid inside the cylinder 601 into the drain pipe 608, and then enters the spray pipe 606 through the support pipe 609 and sprays out. The spray pipe 606 faces the processing frame 102, and can spray the coolant or cutting fluid on the part where the ultrasonic drill 204 contacts the workpiece to achieve a cooling effect. Secondly, through the above-mentioned ultrasonic deep hole processing operation with gradually increasing depth, it is relatively easier to utilize the flushing effect of the coolant or cutting fluid and the chip removal assistance generated by ultrasonic vibration, which is convenient to discharge the chips out of the hole in time under the action of the coolant or cutting fluid; and at the beginning of processing, the depth of the processed hole is relatively shallow, the chip discharge path at the relatively shallow position is short, and it is not easy to appear the dilemma that a large amount of chips accumulate at the bottom of the deep hole and are difficult to discharge, which can effectively avoid the chip blockage problem, ensure the smooth progress of the processing process, and also help to maintain good processing surface quality.

[0039] When the threaded rod 202 drives the ultrasonic base 203 and the ultrasonic drill 204 to move upward, the pressing plate 209 will be driven to move upward. At this time, the pressing plate 209 will no longer press the push plate 605. Under the action of the second spring 603, the third piston 602 can be automatically reset. During the reset process, the cylinder 601 will extract the coolant or cutting fluid in the water tank 6 through the water suction pipe 607 and make it enter the cylinder 601. When the third piston 602 moves downward again, the coolant or cutting fluid in the cylinder 601 can be discharged from the spray pipe 606 to achieve a cooling effect. It should be noted that one-way valves are provided on both the water suction pipe 607 and the drain pipe 608, so that the water suction pipe 607 can only perform the water suction operation, that is, the coolant or cutting fluid enters the cylinder 601 through the water suction pipe 607, while the drain pipe 608 can only achieve the drainage effect, that is, the water flow in the cylinder 601 can be discharged through the drain pipe 608, so as to achieve a cyclic cooling operation.

One end of the adjusting rod 103 placed inside the processing frame 102 is connected to a clamping plate 104. A limiting rod 205 is provided on the ultrasonic base 203. The limiting rod 205 is slidably connected to the support 2. A limiting plate 206 is provided at the top of the limiting rod 205, and a cover plate 208 is also provided on the support 2.

[0041] In this embodiment, the workpiece to be subjected to ultrasonic deep hole machining operation is placed in the machining frame 102, and then the adjusting rod 103 is rotated to drive the clamping plate 104 to move, thereby clamping the workpiece, and then the ultrasonic deep hole machining work on the workpiece can be started. The provided limiting rod 205 can limit the ultrasonic base 203 so that it will not rotate when moving, and the cover plate 208 can play a certain protective role for the various structures and components in the groove 201.
