Description

Technical Field

[0001] This utility model relates to the field of turbine housing production technology, specifically to a surface treatment device for turbine housing production. Background Technology

[0002] In the turbine housing production process, surface treatment is one of the key links to ensure product quality, and various surface treatment devices play an important role in it. These devices remove impurities such as burrs, oxide scale, and stains from the surface of the turbine housing through processes such as grinding, polishing, and cleaning, improve surface roughness, and lay a good foundation for subsequent coating, assembly and other processes. Among them, the vibratory polishing machine is a commonly used surface treatment equipment. With its efficient grinding and polishing capabilities, it is widely used in the surface finishing of turbine housings. Through the high-frequency vibration generated by the vibratory machine, it drives the turbine housing workpiece in the working tank to fully contact and rub against the grinding media, thereby achieving surface deburring, polishing and other treatment effects, and greatly improving the surface quality of the turbine housing.

[0003] However, during the use of existing vibratory polishing machines, grinding debris, workpiece residue, and polishing media powder are easily left on the inner wall of the working tank. If these residual debris are not cleaned in time, they will not only affect the polishing accuracy of the subsequent turbine housing, but may also cause wear on the inner wall of the working tank, shortening the service life of the equipment. Traditional cleaning relies on manual operation, but due to the height and depth of the working tank, it is difficult to fully contact the inner wall during manual cleaning, resulting in time-consuming, labor-intensive, and ineffective cleaning. At the same time, the time-consuming and labor-intensive manual cleaning process greatly reduces the overall production efficiency and brings inconvenience to the surface treatment process of turbine housing production.

[0026] Example 1

[0027] Reference Figure 1-5 This is the first embodiment of the present invention, which provides a surface treatment device for turbine housing production, including a base 1, a working groove 2, a vibrator 3 and a discharge valve port 4. The working groove 2 is fixedly connected to the upper end of the base 1, the vibrator 3 is disposed on the lower side of the working groove 2 and is fixedly connected to the working groove 2, the discharge valve port 4 is fixedly connected to the lower right side of the working groove 2 and communicates with the working groove 2, and an auxiliary cleaning device 5 is provided inside the working groove 2. The auxiliary cleaning device 5 includes a drive component 6, a pressure component 7 and a cleaning brush component 8.

[0028] The drive assembly 6 is located inside the upper part of the working slot 2, the pressure application assembly 7 is located on the lower left side of the drive assembly 6, and the cleaning brush 8 is located on the left side of the pressure application assembly 7.

[0029] Specifically, the device automatically cleans the inner wall of the working tank 2 through the auxiliary cleaning device 5, which solves the problems of manual cleaning being difficult to access, laborious, and inefficient, saving manpower and improving the cleaning effect.

[0030] Furthermore, the drive assembly 6 provides rotational power, driving the pressure assembly 7 and the cleaning brush 8 to move within the working groove 2. The pressure assembly 7 ensures that the cleaning brush 8 fits tightly against the inner wall, and the three work together to complete a comprehensive cleaning of the inner wall of the working groove 2.

[0031] Example 2

[0032] In the second embodiment of this utility model, the drive assembly 6 includes a support frame 61, a motor 62, a transmission shaft 63, and an L-shaped connecting rod 64. The support frame 61 is located on the upper left side of the working groove 2, and its lower left end is fixedly connected to the left side surface of the working groove 2. The motor 62 is fixedly connected to the upper surface of the support frame 61 and is located at the center of the working groove 2. The transmission shaft 63 is fixedly connected to the lower output end of the motor 62, and its lower end passes through the support frame 61 and is rotatably connected to the upper surface of the working groove 2. The transmission shaft 63 is rotatably connected to the support frame 61. The L-shaped connecting rod 64 is sleeved on the surface of the transmission shaft 63 and is fixedly connected to the transmission shaft 63, and its lower left end extends into the interior of the working groove 2.

[0033] The pressure application component 7 includes a support rod 71, a limiting rod 72, a push rod 73, a stainless steel push spring 74, and an arc plate 75. The support rod 71 is fixedly connected to the lower left side of the L-shaped connecting rod 64. There are two limiting rods 72, which are respectively set on the upper and lower sides inside the support rod 71, and their right ends are fixedly connected to the right side surface inside the support rod 71. The push rod 73 is set inside the support rod 71 and is sleeved on the surface of the two limiting rods 72, and is slidably connected to the limiting rods 72. The left end of the push rod 73 extends out of the support rod 71 and is slidably connected to the support rod 71. There are two stainless steel push springs 74, which are respectively sleeved on the right end surface of the two limiting rods 72, and their left and right ends are fixedly connected to the right side of the push rod 73 and the right end inside the support rod 71, respectively. The arc plate 75 is fixedly connected to the left end of the push rod 73.

[0034] An installation slot 11 is provided on the left side of the curved plate 75.

[0035] Specifically, by setting up the cooperation between the drive component 6 and the pressure application component 7, a stable rotational power and contact pressure are provided for the cleaning brush 8, ensuring full coverage and tight cleaning of the inner wall of the working groove 2, effectively improving cleaning efficiency and effect.

[0036] Furthermore, the control motor 62 is started, and the output end of the motor 62 will drive the transmission shaft 63 to start rotating. Since the L-shaped connecting rod 64 is sleeved on the surface of the transmission shaft 63 and fixedly connected to it, the transmission shaft 63 will synchronously drive the L-shaped connecting rod 64 to rotate around the transmission shaft 63 as the axis, so that the part of the lower left end of the L-shaped connecting rod 64 that extends into the working groove 2 will make a circular motion.

[0037] The support rod 71, which is fixedly connected to the lower left side of the L-shaped connecting rod, moves synchronously with the rotation of the L-shaped connecting rod 64, thereby driving the pressure application component 7 and the cleaning brush 8 to make a circular motion inside the working groove 2. In the pressure application component 7, the push rod 73 is sleeved on the surface of the two limit rods 72 and is slidably connected to the limit rods 72. The stainless steel push spring 74 is sleeved on the right end surface of the limit rod 72, and its left and right ends are fixedly connected to the right side of the push rod 73 and the right end of the support rod 71, respectively. When the cleaning brush 8 comes into contact with the inner wall of the working groove 2 with the overall movement, the stainless steel push spring 74 continuously generates an elastic reaction force. This force is transmitted to the arc plate 75 through the push rod 73, and then acts on the rubber clip 81 and the steel wire brush strip 82, so that the steel wire brush strip 82 always fits tightly against the inner wall of the working groove 2.

[0038] Example 3

[0039] In the third embodiment of this utility model, the cleaning brush 8 includes a rubber clip 81 and a steel wire brush strip 82. The rubber clip 81 is disposed inside the mounting slot 11 and extends out of the mounting slot 11 on the left side and is movably connected to the mounting slot 11. The steel wire brush strip 82 is fixedly connected to the left side of the rubber clip 81.

[0040] The steel wire brush strip 82 is in contact with the inner wall of the working groove 2.

[0041] Specifically, by setting the cleaning component 8 to adopt a combination structure of rubber clip 81 and steel wire brush 82, the steel wire brush 82 can effectively clean the impurities on the inner wall of the working groove 2, while the rubber clip 81 and the mounting groove 11 can be quickly disassembled and assembled, thus taking into account both cleaning effect and maintenance convenience.

[0042] Furthermore, as the L-shaped connecting rod 64 continues to rotate, the cleaning brush 8, under the pressure of the stainless steel push spring 74, can closely adhere to the inner wall of the working groove 2 and make a circular motion. The steel wire brush strip 82 will thoroughly clean the impurities such as abrasive debris, oil stains and residual abrasive materials attached to the inner wall of the working groove 2. During this process, cleaning fluid can be injected into the working groove 2 for auxiliary cleaning. The impurities that are brushed off can be discharged from the working groove 2 by opening the discharge valve port 4, thereby achieving efficient cleaning of the inner wall of the working groove 2.

[0043] When replacing the cleaning parts, pull the steel wire brush strip 82 together with the rubber clip 81 upward from the mounting slot 11 on the left side of the arc plate 75, then align the new rubber clip 81 with the steel wire brush strip 82 with the mounting slot 11 and insert it downward and tighten it. This completes the quick replacement of the cleaning parts. The operation is simple and does not require any additional tools, which effectively improves the replacement efficiency of the cleaning brush 8.

[0044] Working principle:

[0045] When cleaning the inner wall of the working groove 2, the control motor 62 is started. The output end of the motor 62 will drive the transmission shaft 63 to start rotating. Since the L-shaped connecting rod 64 is sleeved on the surface of the transmission shaft 63 and fixedly connected to it, the transmission shaft 63 will synchronously drive the L-shaped connecting rod 64 to rotate around the transmission shaft 63 as the axis, so that the part of the lower left end of the L-shaped connecting rod 64 that extends into the interior of the working groove 2 will make a circular motion.

[0046] The support rod 71, which is fixedly connected to the lower left side of the L-shaped connecting rod 64, moves synchronously with the rotation of the L-shaped connecting rod 64, thereby driving the pressure application component 7 and the cleaning brush 8 to make a circular motion inside the working groove 2. In the pressure application component 7, the push rod 73 is sleeved on the surface of the two limit rods 72 and is slidably connected to the limit rods 72. The stainless steel push spring 74 is sleeved on the right end surface of the limit rod 72, and its left and right ends are fixedly connected to the right side of the push rod 73 and the right end of the support rod 71, respectively. When the cleaning brush 8 comes into contact with the inner wall of the working groove 2 with the overall movement, the stainless steel push spring 74 continuously generates an elastic reaction force. This force is transmitted to the arc plate 75 through the push rod 73, and then acts on the rubber clip 81 and the steel wire brush strip 82, so that the steel wire brush strip 82 always fits tightly against the inner wall of the working groove 2.

[0047] As the L-shaped connecting rod 64 continues to rotate, the cleaning brush 8, under the pressure of the stainless steel push spring 74, can closely adhere to the inner wall of the working groove 2 and make a circular motion. The steel wire brush strip 82 will thoroughly clean the impurities such as abrasive debris, oil stains and residual abrasive materials attached to the inner wall of the working groove 2. During this process, cleaning fluid can be injected into the working groove 2 for further cleaning. The impurities that are brushed off can be discharged from the working groove 2 by opening the discharge valve port 4, thereby achieving efficient cleaning of the inner wall of the working groove 2.

[0048] When replacing the cleaning parts, pull the steel wire brush strip 82 along with the rubber clip 81 upward from the mounting slot 11 on the left side of the arc plate 75, then align the new rubber clip 81 with the steel wire brush strip 82 downward and insert it into the mounting slot 11 and tighten it. This completes the quick replacement of the cleaning parts. The operation is simple and does not require any additional tools, which effectively improves the replacement efficiency of the cleaning parts 8 and ensures the continuous and stable operation of the equipment.

[0049] In summary, by using the base 1, working groove 2, vibrator 3, discharge valve 4, auxiliary cleaning device 5, drive assembly 6, support frame 61, motor 62, transmission shaft 63, L-shaped connecting rod 64, pressure assembly 7, support rod 71, limit rod 72, push rod 73, stainless steel push spring 74, arc plate 75, cleaning brush 8, rubber clip 81, steel wire brush strip 82, and mounting slot 11 in combination, automatic cleaning of the inner wall of the working groove is achieved, saving manpower and improving cleaning effect and work efficiency.
