Description

Technical Field

[0001] The utility model relates to the technical field of turbine volute processing, in particular to a deburring device for turbine volute processing. Background Technique

[0002] As the name implies, a volute is a casing that protects a turbine and is mainly processed by casting or equipment such as lathes and milling machines. However, there are many burrs on the surface of the turbine volute after processing. The presence of burrs on the surface of the turbine volute not only affects its performance, but may also cause certain damage to the human body during handling. Therefore, it is necessary to deburr the turbine volute.

[0003] At present, after the turbine volute is processed, manual use of a grinding device is usually used to grind the remaining burrs on its surface. During the operation, it is necessary to walk around the volute, which is not only time-consuming and laborious, but also has low processing efficiency. Therefore, in view of the above problems, we propose a new deburring device for turbine volute processing. Content of the Utility Model

[0004] The utility model mainly provides a time-saving and labor-saving turbine volute processing deburring device with a high degree of automation, convenient use, time-saving and labor-saving, and can effectively improve the deburring efficiency.

[0005] To achieve the above object, the utility model adopts the following technical scheme: a deburring device for turbine volute processing, including a processing table, symmetrically fixedly connected with a first mounting seat and a second mounting seat at a position near the top of the outer surface of the processing table, a grinding mechanism is installed on the top of the first mounting seat, a rotating shaft is installed on the top of the processing table, the top end of the rotating shaft is fixedly connected with a tabletop, a plurality of clamping mechanisms are annularly distributed on the top of the tabletop, the grinding mechanism includes an installation shell, a sliding groove is opened on the outer surface of one side of the installation shell, a sliding table is slidably embedded between the inner walls of the sliding groove, a lead screw is rotatably connected between the inner top and the inner bottom of the sliding groove, an installation groove is opened on the top of the sliding table, a first electric push rod is installed inside the installation groove, the telescopic end of the first electric push rod penetrates through the inner wall of the installation groove and extends to the outside, the telescopic end of the first electric push rod is fixedly connected with an installation frame, and a third motor is installed on the rear surface of the installation frame.

[0006] Preferably, the outer surface of the lead screw is threaded through the outer surface of the sliding table, a second motor is installed on the top of the installation shell, the output end of the second motor penetrates through the top of the installation shell and extends downward, and the output end of the second motor is fixedly connected with the top end of the lead screw. By starting the second motor, the lead screw is driven to rotate. When the lead screw rotates, the sliding table is driven to move up and down inside the sliding groove.

[0007] Preferably, guide rods are symmetrically and fixedly connected to the outer surface of one side of the mounting frame. The guide rods penetrate through the outer surface of the sliding table and extend into the installation groove. When the first electric push rod pushes the mounting frame to move horizontally, the guide rods on the surface of the mounting frame will move synchronously, having a limiting effect and making the movement of the mounting frame more stable.

[0008] Preferably, a fourth motor is rotatably connected between the inner walls of the mounting frame through a rotating block. A grinding head is installed at the output end of the fourth motor. The fourth motor is mainly used to drive the grinding head. When the grinding head rotates at a high speed and approaches the turbine volute workpiece, it can grind the burrs on its surface clean. The grinding head can be replaced with different types according to needs.

[0009] Preferably, a gear sleeve is fixedly connected to the outer surface of the tabletop. A first motor is installed at the bottom of the second mounting seat. The output end of the first motor penetrates through the second mounting seat and extends upward. A gear is fixedly connected to the output end of the first motor. The gear is meshed with the gear sleeve. By starting the first motor, the gear can be driven to rotate. When the gear rotates, it has the effect of driving the gear sleeve to rotate slowly. At this time, the tabletop will drive the turbine volute workpiece to rotate slowly along with the gear sleeve, so as to grind the burrs at different positions on its surface clean.

[0010] Preferably, the clamping mechanism includes a second electric push rod. The second electric push rod is installed at the top of the tabletop near the edge. The telescopic end of the second electric push rod is fixedly connected to a clamping plate. A pressing plate is fixedly connected to the outer surface of the clamping plate. One end of the pressing plate is bent upward. During use, the turbine volute is placed on the tabletop, and then all the second electric push rods are started to drive all the clamping plates to approach each other. When the clamping plates are in close contact with the surface of the turbine volute, the fixing of the turbine volute can be completed. Moreover, during the process of the clamping plate approaching the turbine volute, the pressing plate will coincide with the edge position of the turbine volute in advance. Since the bottom of the pressing plate close to the turbine volute is bent upward, a downward pressure will be applied to the edge of the turbine volute, playing a role in improving the clamping effect, avoiding the shaking of the turbine volute during the processing, and improving the processing quality.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0012] 1. In the present utility model, the second motor, the lead screw and the sliding table cooperate to drive the grinding head to lift. The first electric push rod is used to adjust the distance between the grinding head and the turbine volute. Starting the third motor can adjust the angle of the grinding head. Starting the fourth motor can drive the grinding head to rotate at a high speed. The first motor, the gear and the rack cooperate to drive the tabletop and the turbine volute to rotate. Under the mutual cooperation, the burrs on the surface of the turbine volute can be automatically removed. The overall use is convenient and the degree of automation is relatively high, which can effectively improve the burr treatment efficiency of the surface of the turbine volute.

[0013] 2. In the present utility model, during the process of the clamping plate approaching the turbine volute, the pressing plate will coincide with the edge position of the turbine volute in advance, and the bottom of the pressing plate near the turbine volute is bent upward. Therefore, a downward pressure is applied to the edge of the turbine volute, which improves the clamping effect, avoids the shaking during the machining process of the turbine volute, and improves the machining quality.

[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0020] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0021] Please refer to Figures 1-4, the present utility model provides a technical solution: a deburring device for machining a turbine volute, including a machining table 1. At a position near the top of the outer surface of the machining table 1, a first mounting seat 11 and a second mounting seat 12 are symmetrically and fixedly connected. A grinding mechanism 4 is mounted on the top of the first mounting seat 11. A rotating shaft 2 is mounted on the top of the machining table 1. The top end of the rotating shaft 2 is fixedly connected to a tabletop 21. A plurality of clamping mechanisms 5 are annularly distributed on the top of the tabletop 21. The grinding mechanism 4 includes a mounting shell 401. A sliding groove 402 is formed on the outer surface of one side of the mounting shell 401. A sliding table 403 is slidably embedded between the inner walls of the sliding groove 402. A lead screw 404 is rotatably connected between the inner top and inner bottom of the sliding groove 402. An installation groove 406 is formed on the top of the sliding table 403. A first electric push rod 407 is installed inside the installation groove 406. The telescopic end of the first electric push rod 407 penetrates through the inner wall of the installation groove 406 and extends to the outside. The telescopic end of the first electric push rod 407 is fixedly connected to a mounting frame 409. A third motor 410 is mounted on the rear surface of the mounting frame 409.

[0022] As Figures 1-3 shown, the outer surface of the lead screw 404 is threaded through the outer surface of the sliding table 403. A second motor 405 is mounted on the top of the mounting shell 401. The output end of the second motor 405 penetrates through the top of the mounting shell 401 and extends downward. The output end of the second motor 405 is fixedly connected to the top end of the lead screw 404. By starting the second motor 405, the lead screw 404 is driven to rotate. When the lead screw 404 rotates, the sliding table 403 is driven to move up and down inside the sliding groove 402.

[0023] As Figures 1-3 shown, guide rods 408 are symmetrically and fixedly connected to the outer surface of one side of the mounting frame 409. The guide rods 408 penetrate through the outer surface of the sliding table 403 and extend into the installation groove 406. When the first electric push rod 407 pushes the mounting frame 409 to move horizontally, the guide rods 408 on the surface of the mounting frame 409 will move synchronously, having a limiting effect and making the movement of the mounting frame 409 more stable.

[0024] As Figures 1-3 shown, a fourth motor 411 is rotatably connected between the inner walls of the mounting frame 409 through a rotating block. A grinding head 412 is installed at the output end of the fourth motor 411. The fourth motor 411 is mainly used to drive the grinding head 412. When the grinding head 412 rotates at a high speed and approaches the turbine volute workpiece, the burrs on its surface can be polished clean. The grinding head 412 can be replaced with different types according to needs.

[0025] As Figure 1 and Figure 2As shown, a gear sleeve 32 is fixedly connected to the outer surface of the tabletop 21. A first motor 3 is installed at the bottom of the second mounting seat 12. The output end of the first motor 3 penetrates through the second mounting seat 12 and extends upward. The output end of the first motor 3 is fixedly connected to a gear 31. The gear 31 is meshed with the gear sleeve 32. By starting the first motor 3, the gear 31 can be driven to rotate. When the gear 31 rotates, it drives the gear sleeve 32 to rotate slowly. At this time, the tabletop 21 drives the turbine volute workpiece to rotate slowly with the gear sleeve 32, so as to polish the burrs at different positions on its surface clean.

[0026] As Figure 1 , Figure 2 and Figure 4 As shown, the clamping mechanism 5 includes a second electric push rod 501. The second electric push rod 501 is installed near the edge at the top of the tabletop 21. The telescopic end of the second electric push rod 501 is fixedly connected to a clamping plate 502. A pressing plate 503 is fixedly connected to the outer surface of the clamping plate 502. One end of the pressing plate 503 is bent upward. During use, the turbine volute is placed on the tabletop 21, and then all the second electric push rods 501 are started to drive all the clamping plates 502 to approach each other. When the clamping plates 502 are in close contact with the surface of the turbine volute, the fixation of the turbine volute can be completed. Moreover, during the process of the clamping plate 502 approaching the turbine volute, the pressing plate 503 will coincide with the edge position of the turbine volute in advance. Since the bottom of the pressing plate 503 near the turbine volute is bent upward, a downward pressure will be applied to the edge of the turbine volute, which plays a role in improving the clamping effect, avoids the shaking of the turbine volute during the processing, and improves the processing quality.

[0027] Usage method and working principle of the device: When using this device to remove burrs on the surface of the turbine volute, place the turbine volute on the table 21, and then start all the second electric push rods 501 to drive all the clamping plates 502 to approach each other. When the clamping plates 502 are in close contact with the surface of the turbine volute, the fixation of the turbine volute can be completed. Moreover, during the process of the clamping plate 502 approaching the turbine volute, the pressing plate 503 will coincide with the edge position of the turbine volute in advance, and the bottom of the pressing plate 503 is bent upward when approaching the turbine volute. Therefore, a downward pressure will be applied to the edge of the turbine volute, which plays a role in improving the clamping effect, avoids the shaking of the turbine volute during the processing, improves the processing quality. Then start the fourth motor 411 to drive the grinding head 412 to rotate at a high speed, and start the first electric push rod 407 to push the high-speed rotating grinding head 412 close to the surface of the turbine volute for deburring treatment. During this process, the height of the grinding head 412 can be adjusted by starting the second motor 405 to drive the lead screw 404 to rotate. When the lead screw 404 rotates, it will drive the sliding table 403 to move up and down. The grinding angle of the grinding head 412 can be adjusted by starting the third motor 412 to drive the rotating block to drive the fourth motor 412 to rotate up and down. And starting the first motor 3 can drive the gear 31 to rotate. When the gear 31 rotates, it drives the gear sleeve 32 to rotate slowly. At this time, the table 21 will drive the turbine volute workpiece to rotate slowly along with the gear sleeve 32, so that the grinding head 412 is in contact with the surfaces of different directions of the turbine volute. With the mutual cooperation, the burrs on the surface of the turbine volute can be automatically removed. The overall use is convenient and the degree of automation is relatively high, which can effectively improve the efficiency of deburring the surface of the turbine volute.

[0028] The above are only the preferred embodiments of the present invention, and are not limitations to the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
