Stainless steel is a high-strength metal material with good wear resistance and corrosion resistance. Stainless steel is non-toxic, tasteless and easy to clean. Therefore, stainless steel cups are sturdy, durable, safe and hygienic, and are deeply loved by people. After the stainless steel cup is welded, the burrs on its inner wall are not smooth, so it is necessary to use a grinding device to grind its inner wall, so that the inner wall of the stainless steel cup is smoother and flatter, without obvious scratches, pits and other defects, and the inner wall of the stainless steel cup after grinding is not easy to hide dirt, and it is more convenient to clean. For example, a grinding device for the production of thermos cups with the prior art publication number CN215788835U.

[0003] The existing stainless steel cup polishing device usually uses a motor to drive the polishing head to rotate, and the person manually holds the handle to extend the polishing head into the stainless steel cup, or uses a power device to drive the polishing head to move into the stainless steel cup to polish the inner wall. The polishing efficiency is low, and manual polishing may cause the surface of the stainless steel inner wall to be uneven.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Refer to the instruction manual Figure 1-8 The present invention provides a double-station stainless steel cup inner wall grinding device, comprising a machine platform 1, and two grinding station frames 101 are arranged on the top of the machine platform 1.

[0028] It also includes a clamp 2, which includes two pneumatic chucks 201 for fixing the stainless steel cup. Specifically, the pneumatic chuck 201 is a mechanical clamp with compressed air as the power source. The pneumatic chuck 201 drives the piston or cylinder inside the chuck to move through the compressed air, so that the claws open or clamp the stainless steel cup. The two pneumatic chucks 201 are respectively fixed in two polishing station frames 101, and a limiting mechanism 202 for limiting the stainless steel cup is provided above the two pneumatic chucks 201. Specifically, the limiting mechanism 202 includes a guide rail 2021 fixed in the polishing station frame 101, and two sliders 2022 are slidably provided on the top of the guide rail 2021. Limiting wheels 2023 for improving the rotation stability of the stainless steel cup are installed on the top of the two sliders 2022. The two limiting wheels 2023 are used to limit the stainless steel cup, so as to improve the stability of the stainless steel cup during polishing.

[0029] In addition, telescopic cylinders 2024 for driving the movement of the slider 2022 are fixedly provided on the inner walls on both sides of the two grinding station frames 101. Specifically, the telescopic cylinder 2024 is a pneumatic actuator that converts the energy of compressed air into linear motion mechanical energy. When the compressed air enters the cylinder from one end of the cylinder, it pushes the piston to move forward, thereby extending the piston rod. When the compressed air enters from the other end of the cylinder, it pushes the piston to move backward, thereby retracting the piston rod. By controlling the entry direction of the compressed air, the extension and retraction movement of the piston rod can be realized, thereby driving the slider 2022 to move automatically. A servo motor 203 is fixedly provided at the bottom end of the two pneumatic chucks 201. The servo motor 203 is fixedly embedded in the top of the machine 1. The pneumatic chuck 201 is driven to rotate by the servo motor 203, thereby automatically driving the stainless steel cup to rotate and grind.

[0030] The grinding mechanism 3 is also included, and the grinding mechanism 3 is arranged above the grinding station frame 101. The grinding mechanism 3 includes two mounting plates 301. A reel 302 is fixedly provided on the side away from each other of the two mounting plates 301. A grinding belt 303 is wound on the reel 302. A reel 304 for reeling the grinding belt 303 is fixedly provided on the top of the two mounting plates 301. A long plate 305 is fixedly provided on the side away from each other of the two mounting plates 301. A limit piece 306 is fixedly provided at the front end of the long plate 305. A guide block 307 is fixedly provided at the bottom end of the limit piece 306. The grinding belt 303 successively bypasses the limit piece 306 and the guide block 307 and is reeled on the reel 304.

[0031] Specifically, the limiting member 306 includes two limiting plates 3061 fixed at the front end of the long plate 305, and a plurality of limiting rods 3062 for limiting the position of the grinding belt 303 are fixed between the two limiting plates 3061. The guide block 307 is fixed between the two limiting plates 3061, and is used to guide the grinding belt 303 to contact the inner wall of the stainless steel cup for grinding.

[0032] In addition, an adjusting mechanism 4 for adjusting the height of the mounting plate 301 is fixedly provided on the top of the machine 1. Specifically, the adjusting mechanism 4 includes a vertical plate 401 fixed on the top of the machine 1, and longitudinal electric slides 402 are fixedly provided on both sides of the vertical plate 401. The outer wall of the longitudinal electric slide 402 is connected to a transverse electric slide 403, and the mounting plate 301 is fixed on the transverse electric slide 403. By cooperating with the transverse electric slide 403 and the longitudinal electric slide 402, the position of the guide block 307 can be automatically adjusted.

[0033] The longitudinal electric slide 402 and the transverse electric slide 403 are both composed of a combination of a linear slide and a motor drive, and the motor drive is used to drive the workpiece to automatically move linearly.

[0034] When in use, the staff first places two stainless steel cups inside the two pneumatic chucks 201 respectively, and then the telescopic cylinder 2024 drives the limit wheel 2023 on the slider 2022 to contact the outer wall of the stainless steel cup. After that, the servo motor 1 203 drives the stainless steel on the pneumatic chuck 201 to rotate, and at the same time, the limit piece 306 and the guide block 307 are driven to move into the stainless steel cup with the help of the adjustment mechanism 4. While the stainless steel cup rotates, its inner wall contacts the grinding belt 303 on the guide block 307, thereby realizing the automatic grinding of the inner wall of the stainless steel cup. After the grinding is completed, the limit piece 306 and the guide block 307 are automatically removed from the stainless steel cup, and the staff takes out the polished stainless steel cup and then places a new stainless steel cup. This embodiment can realize double-station grinding by setting two grinding station frames 101 on the machine 1, which greatly improves the grinding efficiency of the stainless steel cup, and can also improve the smoothness and flatness of the inner wall of the stainless steel cup, thereby improving product quality.

[0035] In actual use, a control box is installed on the machine 1 to control the operation of the servo motor 1 203, the longitudinal electric slide 402, the transverse electric slide 403, and the servo motor 2 10 of the present invention, and the control box is equipped with a built-in battery for power supply. The staff issues instructions through the control box, and the entire device performs automatic grinding according to a pre-set program. The above technologies are all existing commonly used technologies and will not be further elaborated here.

[0036] Refer to the instruction manual Figure 1-4 A support plate 9 is fixedly provided on the top of the two mounting plates 301, and the winding roller 304 is rotatably connected to the support plate 9. A servo motor 10 is fixedly provided on one side of the two support plates 9. One end of the output shaft of the servo motor 10 penetrates the support plate 9 and is fixed to the winding roller 304. The servo motor 10 is used to drive the winding roller 304 to rotate, so as to realize automatic adjustment of the grinding belt 303 at the guide block 307.

[0037] Servo motor one 203 and servo motor two 10 are both rotary actuators or linear actuators that allow precise control of angular velocity or linear position, speed and acceleration.

[0038] After polishing each stainless steel cup, the servo motor drives the winding roller 304 to rotate, so that the polishing belt 303 on the unwinding roller 302 is stretched, and the polishing belt 303 is wound onto the winding roller 304 via the guide wheel 2 8, the long plate 305, the guide block 307, the limiter 306, the limiter 5 and the guide wheel 1 6, so as to realize the automatic replacement of the polishing belt 303 at the guide block 307, thereby ensuring the polishing effect of the inner wall of the stainless steel cup. After the use of the polishing belt 303 is finished, the staff can remove the unwinding roller 302 and the winding roller 304 in turn and replace them with a new polishing belt 303.

[0039] Refer to the instruction manual Figure 1-6A dust suction pipe 11 is fixedly passed through the rear ends of the two grinding station frames 101, and the dust suction pipe 11 is connected to the inside of the grinding station frame 101. An industrial vacuum cleaner 12 is fixedly arranged at the rear end of the machine 1. Specifically, the industrial vacuum cleaner 12 can be used for waste collection, dust collection, air filtering and purification, and environmental cleaning in the industrial production process. The bottom ends of the two dust suction pipes 11 are connected to the industrial vacuum cleaner 12.

[0040] By arranging an industrial vacuum cleaner 12 behind the machine 1, the industrial vacuum cleaner 12 generates suction during grinding, and the dust generated by grinding in the grinding station frame 101 is sucked into the industrial vacuum cleaner 12 through a hose, thereby reducing the harm caused by the dust.

[0041] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
