Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to ultrasonic processing equipment. Background Technology

[0002] Ultrasonic processing equipment is a special processing system that utilizes the synergistic effect of high-frequency mechanical vibration and abrasive. It is mainly used for cutting and processing hard and brittle materials such as ceramics, glass, and monocrystalline silicon.

[0003] A patent for an ultrasonic cutting machine with an automatic blade cleaning system (publication number CN209831816U) was found in China. This patent includes a hollow housing. A mounting plate is connected to the upper inner wall of the housing via a lifting mechanism. The mounting plate is connected to a connecting plate via an adjusting mechanism. The connecting plate is connected to the ultrasonic cutting machine body via a rotating mechanism. A cutting blade is located at the lower end of the ultrasonic cutting machine body. A feed inlet communicating with the interior of the housing is located on one side wall, and a cover plate is rotatably connected to the opening of the feed inlet. An upward-opening storage groove is located on the lower inner wall of the housing. This invention cleans the cutting blade before each material cutting operation, ensuring the blade is clean for the next cut, guaranteeing proper material cutting, improving material processing quality, and allowing water to enter a storage chamber through a drainage hole for recycling, thus reducing production costs.

[0004] This patented technology has the advantage of automatically cleaning the cutting blade during use, but it still has shortcomings. The cutting blade is exposed to the outside world, making it easy to accidentally touch and injure oneself. Furthermore, because ultrasonic kinetic energy is applied, accidental contact can worsen injuries, resulting in low safety performance. Therefore, those skilled in the art have provided an ultrasonic processing device to solve the problems mentioned in the background art. Utility Model Content

[0005] 1. Technical Solution

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an ultrasonic processing device, comprising a processing table, a negative pressure pump, a fixed frame, a hydraulic rod, a protective sleeve, and a cutting blade. A mounting frame is fixed to the rear side of the processing table. A hydraulic rod is installed inside the mounting frame. An ultrasonic generator is installed at the lower end of the hydraulic rod. A piezoelectric transducer is installed at the lower end of the ultrasonic generator. An amplitude transformer is installed at the lower end of the piezoelectric transducer. A cutting blade is installed at the lower end of the amplitude transformer. A symmetrically distributed protective sleeve is fitted around the outside of the cutting blade. A fixed frame is fitted around the outer wall of the ultrasonic generator. Symmetrically distributed supports are installed on both sides below the fixed frame. A longitudinally distributed spring 1 is installed between the support and the fixed frame, and a transversely distributed spring 2 is installed between the support and the protective sleeve.

[0008] Furthermore, the upper end of the processing table is provided with side frames on both the front and rear sides, the side frames are open inside, and the protective sleeve is provided with side rods at both ends that are connected to the bracket and located above the side frames;

[0009] Specifically, the bracket descends along with the fixed frame, which in turn lowers the side rod. When the side rod contacts the side frame, it applies resistance to the bracket, preventing the side rod and bracket from descending continuously. The open-shaped side frame has the advantage of expanding the field of vision during cutting.

[0010] Furthermore, each of the brackets is embedded with a longitudinally distributed sliding sleeve, and the lower end of the fixing frame is provided with a guide rod located inside the spring and slidably installed inside the sliding sleeve.

[0011] Specifically, the guide rod slides inside the sliding sleeve. When the spring moves longitudinally, it is limited by the guide rod to prevent the spring from shifting outward. This limits the spring and improves the stability of the spring's extension and retraction process.

[0012] Furthermore, each of the brackets is embedded with a horizontally distributed sliding sleeve II, and one end of the protective sleeve is provided with a guide rod II located inside the spring II and slidably installed inside the sliding sleeve II;

[0013] Specifically, the guide rod 2 slides inside the sliding sleeve 2. When the spring 2 moves longitudinally, it is limited by the guide rod 2 to prevent the spring 2 from shifting outward. This limits the spring 2 and improves the stability of the spring 2's extension and retraction process.

[0014] Furthermore, the inner wall of the protective sleeve is conical, and the lower end of the fixing frame is provided with symmetrically distributed support rods, and the lower end of the support rods is provided with compression blocks;

[0015] Specifically, when the inner wall of the conical protective sleeve is squeezed by the pressure block, an increasing pressure is gradually applied, which is applied to the longitudinally distributed spring one and the transversely distributed spring two.

[0016] Furthermore, a ball bearing that rolls against the inner wall of the protective sleeve is rotatably installed inside one side of the extrusion block;

[0017] Specifically, when the extrusion block applies pressure to the inner wall of the protective sleeve, the ball bearings adhere to the inner wall of the protective sleeve, reducing the friction and resistance when the extrusion block passes through.

[0018] Furthermore, a processing area is provided at the upper end of the processing table, the interior of the processing table is hollow, and adsorption holes are equally distributed and located inside the processing area at the upper end of the processing table. A negative pressure pump with its suction end penetrating through the processing table is provided at the lower end of the processing table.

[0019] Specifically, the workpiece to be ultrasonically cut is placed in the processing area and supported by the processing table. The suction force of the negative pressure pump is transmitted to the adsorption hole through the hollow processing table, and the small solid workpiece is adsorbed and fixed through the adsorption hole.

[0020] 2. Beneficial effects

[0021] Compared with existing technologies, the advantages of this utility model are:

[0022] In this invention, the workpiece is placed on a processing table, and a hydraulic rod drives the cutting blade to move longitudinally. Upon contact with the workpiece, high-frequency vibration force facilitates cutting. During use, the cutting blade is protected by relatively distributed protective sleeves. When the cutting blade descends to a set height, the protective sleeves are intercepted to prevent further descent. A spring compensates for the continuous longitudinal movement of the cutting blade. As the cutting blade descends, synchronously moving extrusion blocks press against the inner wall of the protective sleeves, causing the sleeves to extend outwards and move to the sides, preventing contact between the sleeves and the workpiece while ensuring effective cutting. When the cutting blade is raised, springs one and two reset the protective sleeves, covering the outside of the cutting blade and protecting it. The cutting blade is only exposed briefly when in contact with the workpiece, reducing the possibility of accidental contact and improving safety during ultrasonic cutting.

[0023] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0036] Example 1

[0037] Please see Figure 1-5As shown, this embodiment is an ultrasonic processing equipment, including a processing table 1, a negative pressure pump 5, a fixed frame 6, a hydraulic rod 7, a protective sleeve 9, and a cutting blade 13. A mounting frame 8 is fixed on the rear side of the upper part of the processing table 1. A hydraulic rod 7 is installed inside the mounting frame 8. An ultrasonic generator 10 is installed at the lower end of the hydraulic rod 7. A piezoelectric transducer 11 is installed at the lower end of the ultrasonic generator 10. An amplitude transformer 12 is installed at the lower end of the piezoelectric transducer 11. A cutting blade 13 is installed at the lower end of the amplitude transformer 12. A symmetrically distributed protective sleeve 9 is sleeved on the outside of the cutting blade 13. A fixed frame 6 is sleeved on the outer wall of the ultrasonic generator 10. A symmetrically distributed bracket 17 is installed on both sides below the fixed frame 6. A longitudinally distributed spring 14 is installed between the bracket 17 and the fixed frame 6. A transversely distributed spring 16 is installed between the bracket 17 and the protective sleeve 9.

[0038] The processing table 1 has side frames 2 on both the front and rear sides at the top. The inside of the side frames 2 is open. The protective sleeve 9 has side rods 15 at both ends that are connected to the bracket 17 and located above the side frames 2.

[0039] Each bracket 17 has a longitudinally distributed sliding sleeve embedded inside it, and the lower end of the fixed bracket 6 has a guide rod 18 located inside the spring 14 and slidably installed inside the sliding sleeve.

[0040] The bracket 17 is embedded with horizontally distributed sliding sleeves 2. One end of the protective sleeve 9 is provided with a guide rod 20 located inside the spring 2 16 and slidably installed inside the sliding sleeve 2.

[0041] The inner wall of the protective sleeve 9 is conical 22, and the lower end of the fixing frame 6 is provided with symmetrically distributed support rods 19, and the lower end of the support rods 19 is provided with compression blocks 21.

[0042] The inner side of the extrusion block 21 is equipped with a ball bearing 23 that rotates and rolls against the inner wall of the protective sleeve 9;

[0043] The upper end of the processing table 1 is provided with a processing area 3. The interior of the processing table 1 is hollow. The upper end of the processing table 1 has equally spaced adsorption holes 4 located inside the processing area 3. The lower end of the processing table 1 is provided with a negative pressure pump 5 with the suction end penetrating through the processing table 1.

[0044] In this embodiment, when using the ultrasonic processing equipment, the workpiece to be cut is first placed in the processing area 3 at the top of the processing table 1. The processing table 1 supports the workpiece. The hydraulic rod 7 is activated, and the hydraulic rod 7 drives the ultrasonic generator 10 to move downward. The ultrasonic generator 10 converts the high-frequency electrical signal into high-frequency mechanical vibration, and transmits the vibration to the amplitude transformer 12 through the piezoelectric transducer 11. The amplitude transformer 12 amplifies the vibration and transmits it to the cutting blade 13, causing the cutting blade 13 to generate high-frequency vibration. Thus, the workpiece is cut by utilizing the synergistic effect of high-frequency vibration and abrasive.

[0045] As the cutting blade 13 moves downward, the fixed frame 6 descends with the hydraulic rod 7, causing the support 17 and the side rod 15 to descend. When the side rod 15 contacts the side frame 2, the side frame 2 applies resistance to the support 17 to prevent the support 17 and the side rod 15 from continuing to descend. At this time, the cutting blade 13 descends to the set height, contacts the workpiece, and cuts. During the descent of the cutting blade 13, the support 17 moves synchronously, causing the extrusion block 21 to extrude force on the inner wall of the protective sleeve 9. Since the inner wall of the protective sleeve 9 is conical 22, the extrusion force of the extrusion block 21 on the inner wall of the protective sleeve 9 gradually increases, causing the protective sleeve 9 to extend outwards. The shielded protective sleeve 9 moves to both sides to prevent the protective sleeve 9 from contacting the workpiece being cut, ensuring the effective cutting of the cutting blade 13. At the same time, the spring 14 and the spring 26 are compressed during the movement of the extrusion block 21, ensuring the continuous longitudinal descent of the cutting blade 13 and the lateral movement of the protective sleeve 9 outwards.

[0046] After the cutting process is completed, the hydraulic rod 7 drives the cutting blade 13 to rise. The spring 14 and the spring 2 16 cause the bracket 17 and the protective sleeve 9 to return to their original positions under the action of elastic force. The protective sleeve 9 covers the outside of the cutting blade 13 and protects the cutting blade 13. The cutting blade 13 is protected by the relatively distributed protective sleeves 9 and is only exposed for a short time during the cutting process, which greatly reduces the possibility of accidental contact. During the cutting process, the suction force of the negative pressure pump 5 is transmitted to the adsorption hole 4 through the hollow processing table 1. The small solid workpiece is adsorbed and fixed through the adsorption hole 4 to ensure the stability of the workpiece.

[0047] This ultrasonic processing equipment uses a protective sleeve 9 to protect the cutting blade 13, exposing it only briefly during cutting. This effectively solves the problem of the traditional ultrasonic cutting machine's cutting blade 13 being exposed and prone to accidental injury, thus improving safety during ultrasonic cutting. Simultaneously, the equipment uses a hydraulic rod 7 to drive the cutting blade 13, enabling convenient cutting of the workpiece. The design of the spring and bracket 17 allows the protective sleeve 9 to automatically unfold when the cutting blade 13 descends and automatically reset when it rises, simplifying operation and improving processing efficiency. Furthermore, the equipment uses a negative pressure pump 5 and suction holes 4 to adhere and fix the workpiece, ensuring its stability and further improving processing quality.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
