DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1, reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, and provides a double-station automatic inner surface polishing machine, which can achieve the polishing effect of the double-station automatic inner surface polishing machine, and includes a double-station automatic inner surface polishing machine, including a base 1 and a mechanical arm 2, the mechanical arm 2 clamps a workpiece 3 to be polished, and the double-station automatic inner surface polishing machine includes a collecting box 4 fixedly installed on the base 1, a driving mechanism 5 is fixedly installed on the base 1, a dustproof mechanism 6 and a mounting mechanism 7 are fixedly connected to the driving mechanism 5, a polishing mechanism 8 is fixedly connected to the mounting mechanism 7, and a drainage mechanism 9 is fixedly connected to the polishing mechanism 8; Specifically, the base 1 cooperates with the robotic arm 2 to realize the loading and unloading and fixing of the workpiece 3 to be polished. The robotic arm 2 picks up the workpiece 3 to be polished from the placement area and places it on the base 1. The robotic arm 2 cooperates with the base 1 to fix the workpiece 3 to be polished. At this time, the driving mechanism 5 is started, and the driving mechanism 5 drives the installation mechanism 7 and the polishing mechanism 8 to operate. The driving mechanism 5 drives the polishing mechanism 8 to penetrate into the workpiece 3 to be polished and polish it. At the same time, the dustproof mechanism 6 blocks one end of the workpiece 3 to be polished to prevent dust from overflowing. The drainage mechanism 9 introduces the polishing liquid into the workpiece 3 to be polished, and cooperates with the polishing mechanism 8 to polish the workpiece 3 to be polished. After polishing, the driving mechanism 5 is reset, and the robotic arm 2 is started to take out the workpiece 3 to be polished.

[0030] The polishing mechanism 8 includes a placement groove 80 and a bottom groove 81 opened on the mounting mechanism 7. The inner wall of the bottom groove 81 is slidably connected with a bottom rod 82. The top of the bottom rod 82 is fixedly connected with a fixed cross frame 83. The fixed cross frame 83 is adapted to the placement groove 80. A polishing plate 84 is fixedly connected to the fixed cross frame 83. A through hole 85 is opened on the fixed cross frame 83, and a reset ring 86 is arranged inside the through hole 85.

[0031] Among them, there are multiple fixed cross frames 83, and multiple fixed cross frames 83 are distributed in a circular array around the mounting mechanism 7. The cross-section of the through hole 85 is circular, and the inner wall of the through hole 85 fits with the reset ring 86. The reset ring 86 is made of rubber material. The setting of the placement groove 80 can limit the fixed cross frame 83. During the operation, the fixed cross frame 83 is embedded in the mounting mechanism 7 to reserve space for the polishing plate 84, so that the space utilization rate of the device is higher and the equipment is more compact. At the same time, the bottom rod 82 cooperates with the bottom groove 81 to limit the fixed cross frame 83. After the fixed cross frame 83 is limited, the polishing plate 84 can be limited. When the mounting mechanism 7 rotates, the fixed cross frame 83 drives the polishing plate 84 to fit with the inner wall of the workpiece 3 to be polished under the action of centrifugal force, and at the same time pulls the reset ring 86, so that the reset ring 86 stretches and accumulates elastic potential energy. After the polishing is completed, the reset ring 86 drives the fixed cross frame 83 and the polishing plate 84 to reset, which is convenient for the next polishing work.

[0032] In summary, the polishing mechanism 8 can perform the polishing work on the workpiece 3 to be polished. During polishing, spraying the polishing liquid through the discharge mechanism 9 can effectively reduce the output of flying dust. At the same time, it cooperates with the dustproof mechanism 6 to realize the dust reduction function. The contact between the polishing liquid and the polishing mechanism 8 can cool down the polishing mechanism 8 and reduce the occurrence of overheating of the polishing mechanism 8.

[0033] Example 2, reference Figures 1 to 9 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a driving mechanism 5 and a dustproof mechanism 6 of a double-station automatic inner surface polishing machine, which solves the driving and dustproof problems of the double-station automatic inner surface polishing machine. The driving mechanism 5 includes an electric telescopic rod 50 fixedly connected to the base 1, and the driving end of the electric telescopic rod 50 is fixedly connected to a fixed seat 51. The fixed seat 51 is slidably connected to the base 1 through a slide rail 52. A driving motor 53 is fixedly connected to the fixed seat 51, and a driving rod 54 is fixedly connected to the driving end of the driving motor 53.

[0034] Furthermore, the electric telescopic rod 50 can drive the fixed seat 51 to move along the slide rail 52 when working. The setting of the slide rail 52 can effectively limit the fixed seat 51 and the driving motor 53. After the driving motor 53 is limited, the driving rod 54 connected to the driving motor 53 is also limited. The limited driving rod 54 can stably enter the interior of the workpiece 3 to be polished. The driving motor 53 can drive the driving rod 54 to rotate, and the electric telescopic rod 50 can drive the driving rod 54 to move along the slide rail 52.

[0035] The dust prevention mechanism 6 includes a bottom cylinder 60 slidably connected to the driving rod 54, a middle ring 61 and a base ring 62 rotatably connected to the driving rod 54, a collecting cover 63 fixedly connected to the bottom cylinder 60, a liquid discharge pipe 64 fixedly connected to the bottom of the collecting cover 63, and a first elastic rope 65 fixedly connected between the bottom cylinder 60 and the base ring 62. The first elastic rope 65 passes through the middle ring 61, and the number of the first elastic ropes 65 is multiple, and the multiple first elastic ropes 65 are distributed in a ring array between the bottom cylinder 60 and the base ring 62, the collecting cover 63 is in contact with the outer wall of the workpiece 3 to be polished, and the liquid discharge pipe 64 is located at the lowest point of the inner wall of the collecting cover 63.

[0036] Among them, the cross-section of the bottom cylinder 60 is circular, and the circular bottom cylinder 60 can better adapt to the driving rod 54. The middle ring 61 and the base ring 62 are both rotatably connected to the driving rod 54, which can prevent the first elastic rope 65 from being entangled when the driving rod 54 rotates. The outer wall of the middle ring 61 fits with the inner wall of the bottom cylinder 60. The base ring 62 can apply tension to the first elastic rope 65 when entering the interior of the workpiece 3 to be polished. The tension can drive the bottom cylinder 60 and the collecting cover 63 to move, so that the collecting cover 63 fits with the workpiece 3 to be polished. At this time, dust prevention work can be performed to prevent flying dust from being discharged from the end of the workpiece 3 to be polished close to the driving motor 53. The first elastic rope 65 is woven from elastic fibers. The setting of the two collecting covers 63 can seal the polishing mechanism 8 inside the workpiece 3 to be polished, which can effectively prevent flying dust from escaping.

[0037] The mounting mechanism 7 includes a middle rod 70 and side plates 71 at both ends of the middle rod 70. The driving rod 54 is fixedly connected to one of the side plates 71. A rubber cover 73 is fixedly connected to the side plate 71. The placement groove 80 and the bottom groove 81 are provided on the side plate 71. The outer wall of the rubber cover 73 fits the inner wall of the workpiece 3 to be polished. The end of the side plate 71 away from the middle rod 70 is arc-shaped.

[0038] Specifically, the setting of the middle rod 70 can fix the side plate 71, and the setting of the side plate 71 can effectively limit the polishing mechanism 8, so that the polishing mechanism 8 can effectively polish the workpiece 3 to be polished, and the setting of the rubber cover 73 can limit the flying dust and the polishing liquid to prevent the flying dust from escaping.

[0039] The rest of the structure is the same as that of Example 1.

[0040] In summary, when the base ring 62 enters the interior of the workpiece 3 to be polished, it can apply tension to the first elastic rope 65, and the tension can drive the bottom cylinder 60 and the collecting cover 63 to move, so that the collecting cover 63 fits the workpiece 3 to be polished. At this time, dust prevention work can be performed to prevent flying dust from being discharged from the end of the workpiece 3 to be polished close to the drive motor 53.

[0041] Example 3, reference Figures 1 to 9 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a liquid guide assembly 90 of a double-station automatic inner surface polishing machine, which solves the problem of polishing liquid discharge of the double-station automatic inner surface polishing machine. The discharge mechanism 9 includes a liquid guide assembly 90 and a barrier assembly 91. The barrier assembly 91 is provided with a release assembly 92. The liquid guide assembly 90 includes a liquid storage cavity 900 opened on the middle rod 70 and the side plate 71. The setting of the liquid storage cavity 900 can store the polishing liquid. The liquid storage cavity 900 is remote. One end of the driving rod 54 is fixedly connected with a liquid inlet pipe 901, and the liquid inlet pipe 901 is set to introduce the external polishing liquid into the liquid storage chamber 900. The other end of the liquid inlet pipe 901 passes through the collection box 4 and the base 1 and is rotatably connected with a hose 902, which is connected to an external liquid inlet pump. The setting of the hose 902 can make a soft connection between the external liquid inlet pump and the liquid inlet pipe 901 to avoid affecting the operation of the external liquid inlet pump due to the movement of the liquid inlet pipe 901. The above-mentioned external liquid inlet pump is a prior art and will not be described in detail here. Among them, the setting of the liquid guiding component 90 can introduce and store the external polishing liquid, the setting of the blocking component 91 can block the stored polishing liquid to prevent it from being discharged, and the setting of the releasing component 92 can discharge the stored polishing liquid.

[0042] The blocking assembly 91 includes two rectangular grooves 910 formed on the middle rod 70, two blocking seats 911 and two releasing seats 912 are fixedly connected inside the rectangular grooves 910, a blocking cavity 913 is provided between the two blocking seats 911 and the two releasing seats 912, a blocking groove 914 is provided between the two blocking seats 911, and a discharge slit 915 is provided between the blocking seat 911 and the corresponding releasing seat 912; Furthermore, the rectangular groove 910 can limit the blocking seat 911 and the release seat 912. The two blocking seats 911 and the two release seats 912 together form a blocking cavity 913. The blocking cavity 913 can control the flow direction of the polishing liquid. The blocking groove 914 and the discharge slit 915 are both outflow channels for the polishing liquid. The discharge slit 915 can discharge the polishing liquid in a more dispersed manner, and the dispersed polishing liquid can fall more evenly on the inside of the workpiece 3 to be polished.

[0043] The release assembly 92 includes an adjustment plate 920 arranged inside the blocking cavity 913, and the end of the adjustment plate 920 close to the liquid storage cavity 900 is fixedly connected to the second elastic rope 921, and the end of the adjustment plate 920 away from the second elastic rope 921 is fixedly connected to a sealing plate 922, and the end of the sealing plate 922 away from the adjustment plate 920 is fixedly connected to the third elastic rope 923, and the other end of the third elastic rope 923 is fixedly connected to the reset ring 86, and the middle rod 70 is located on both sides of the sealing plate 922 and is fixedly connected to the limiting frame 924.

[0044] Among them, the setting of the adjustment plate 920 can control the opening and closing of the blocking chamber 913. When one side of the adjustment plate 920 is in contact with the blocking seat 911, the polishing liquid in the liquid storage chamber 900 cannot be discharged. When the adjustment plate 920 is in contact with the release seat 912, the polishing liquid in the liquid storage chamber 900 is discharged to the inner wall of the workpiece 3 to be polished through the blocking groove 914, the blocking chamber 913 and the discharge slit 915. The second elastic rope 921 can drive the adjustment plate 920 to reset.

[0045] The cross section of the liquid storage chamber 900 is circular, the discharge slit 915 is arc-shaped, the side of the adjustment plate 920 close to the blocking groove 914 is matched with the blocking seat 911, the end of the adjustment plate 920 away from the blocking groove 914 is matched with the release seat 912, the end of the adjustment plate 920 close to the blocking groove 914 is arc-shaped, and the arc-shaped end of the adjustment plate 920 is matched with the discharge slit 915. The number of the adjustment plates 920 is even and one-to-one corresponding, the two corresponding adjustment plates 920 are connected by a second elastic rope 921, and the limit frame is slidably connected with the sealing plate 922.

[0046] The rest of the structure is the same as that of Example 2.

[0047] During operation, the workpiece 3 to be polished is picked up by the mechanical arm 2 and placed on the base 1. At this time, the base 1 cooperates with the mechanical arm 2 to complete the positioning of the workpiece. At this time, the electric telescopic rod 50 in the driving mechanism 5 is started, and the electric telescopic rod 50 drives the driving motor 53 and the driving rod 54 to move. When the driving rod 54 brings the polishing mechanism 8 into the interior of the workpiece 3 to be polished, the dustproof mechanism 6 blocks one end of the workpiece 3 to be polished to prevent dust from leaking out. The driving motor 53 is started, and the driving motor 53 drives the driving rod 54 to rotate. The rotating driving rod 54 drives the polishing mechanism 8 to rotate. When the polishing mechanism 8 rotates, the fixed cross frame 83 drives the polishing plate 84 to fit the inner wall of the workpiece 3 to be polished under the action of centrifugal force, and at the same time pulls the reset ring 86 to expand, so that the reset ring 86 stretches The elastic potential energy is accumulated. During the expansion of the reset ring 86, the third elastic rope 923 is driven to move. The movement of the third elastic rope 923 drives the sealing plate 922 to move. The movement of the sealing plate 922 drives the adjustment plate 920 to move from the blocking seat 911 to the release seat 912. At this time, the polishing liquid in the liquid storage chamber 900 is discharged to the inner wall of the workpiece 3 to be polished through the blocking groove 914, the blocking chamber 913 and the discharge slit 915. The discharge mechanism 9 introduces the polishing liquid into the workpiece 3 to be polished, and cooperates with the polishing mechanism 8 to polish the workpiece 3 to be polished. After the polishing is completed, the reset ring 86 drives the fixed cross frame 83 and the polishing plate 84 to reset. When the polishing mechanism 8 moves to the other end of the workpiece 3 to be polished, the rubber cover 73 squeezes the waste liquid inside the workpiece 3 to be polished into the collection box 4. After polishing is completed, the driving mechanism 5 is reset, and the robotic arm 2 is started to take out the workpiece 3 to be polished. When the driving mechanism 5 is reset, the rubber cover 73 scrapes one side of the inner wall of the workpiece 3 to be polished, and takes out the waste liquid attached to the inner wall of the workpiece 3 to be polished, and takes it into the collecting cover 63. The waste liquid entering the collecting cover 63 can be discharged through the drain pipe 64.

[0048] In summary, the setting of the liquid guiding component 90 can introduce and store the external polishing liquid, the setting of the barrier component 91 can block the stored polishing liquid to prevent it from being discharged, and the setting of the release component 92 can discharge the stored polishing liquid.
