When the sewing machine accessories are fixed by the limit component 87, the operator places the sewing machine accessories on the surface of the fixed platform 871 in the limit component 87, and then turns the knob 875 to drive the clamping block 874 and the forward and reverse screw rods 872 to rotate in the fixed platform 871. Then, the limit block 873 slides toward or in the opposite direction along the inner wall of the fixed platform 871, so as to limit the accessories horizontally according to their specific sizes.

[0039] As the limiting component 87 moves upward following the support plate 85, the connecting frame 878 gradually moves upward, and its bottom is now in contact with the right-angled edge of the top of the right-angle plate 89. Under the elastic force of the elastic telescopic tube 88, the right-angle plate 89 can pull the limiting card plate 876 downward through the connecting frame 878, so that the spring sheet 877 is elastically deformed under the force, and at the same time, the limiting card plate 876 is stuck on the surface of the card block 874, thereby limiting the rotation of the card block 874 and the forward and reverse screws 872, preventing the grinding belt 4 from slipping when in contact with the sewing machine accessories.

[0040] The synchronization component 9 includes a fixed column 91, the outer wall of the fixed column 91 is slidably connected to a limit plate 92, the top of the limit plate 92 is fixedly connected to a compression spring 93, the top of the compression spring 93 is fixedly connected to a connecting plate 94, the bottom of the connecting plate 94 is fixedly connected to a piston rod 95, the outer wall of the piston rod 95 is slidably connected to an oil storage cylinder 96, the two sides of the top of the oil storage cylinder 96 are fixedly connected to an oil guide cylinder 97, the inner wall of the oil guide cylinder 97 is slidably connected to a push rod 98, the bottom end of the push rod 98 is fixed A paddle plate 99 is connected, the bottom of the fixed column 91 is fixedly connected to the outer side of the mounting plate 2, the inner side of the mounting plate 2 is slidably connected to the outer side of the limit plate 92, the outer wall of the paddle plate 99 is slidably connected to the inner side of the mounting plate 2, the top of the connecting plate 94 is slidably connected to the outer wall of the fixed column 91, the outer sides of the oil guide cylinder 97 and the oil storage cylinder 96 are fixedly connected to the outer side of the mounting plate 2, the bottom of the paddle plate 99 is in contact with the top of the support plate 85, and the bottom of the limit plate 92 is in contact with the inner side of the grinding belt 4 When the support plate 85 is displaced to the bottom of the grinding belt 4, the protrusion on the outer side of the support plate 85 just rests on the bottom of the dial plate 99 in the synchronous assembly 9. At this time, as the support plate 85 gradually moves upward, the dial plate 99 gradually drives the push rod 98 to move upward together, thereby squeezing the hydraulic oil in the oil guide cylinder 97 into the oil storage cylinder 96. At this time, as the hydraulic oil in the oil storage cylinder 96 gradually increases, the piston rod 95 gradually drives the connecting plate 94 to move downward along the fixed column 91. At this time, the connecting plate 94 can press the limit plate 92 downward through the compression spring 93 to ensure the stability of the friction between the grinding belt 4 and the sewing machine accessories, thereby improving the grinding effect and quality. Among them, the maximum sliding limit of the limit plate 92 is limited by the mounting plate 2. When the limit plate 92 runs to the lower dead point, as the support plate 85 continues to move upward, the piston rod 95 synchronously drives the connecting plate 94 to move downward continuously, forcing the compression spring 93 to be further compressed, thereby enabling it to play the role of overload protection.

[0041] Working principle: when in use, the polishing device is based on the base 1 as the basic supporting structure, the mounting plate 2 is fixed on the top of the base 1, and the motor is installed on the outside of the mounting plate 2, so that it can drive any pulley 3 to rotate. When the pulley 3 rotates, the grinding belt 4 set on the outside can run synchronously. Then, the sewing machine accessories are fixed by the limiting component 87 in the fixing component 8. The servo motor 7 drives the fixing component 8 to rotate intermittently, and ensures that the rotation angle of the servo motor 7 is 90 degrees each time. When the servo motor 7 stops rotating, the telescopic cylinder 5 contracts. , so that the top seat 6 moves upward, and the top seat 6 can lift the bottom plate 84 located on its top, so that it drives the support plate 85 to move upward through the guide rod 83. At this time, the limiting component 87 and the sewing machine accessories can approach the grinding belt 4. When the accessories come into contact with the high-speed grinding belt 4, the abrasive on the grinding belt 4 will grind the surface of the accessories to remove surface defects, burrs, etc., thereby completing the grinding work. In this process, when the support plate 85 moves upward, the synchronous component 9 can move synchronously to ensure that the grinding belt 4 is in full contact with the sewing machine accessories.

[0042] By setting the tension spring 86, during the intermittent rotation of the turntable 81, when the top seat 6 lifts up the bottom plate 84 on its top, the distance between the support plate 85 and the fixed plate 82 becomes larger, thereby forcing the tension spring 86 to be stretched. The tension spring 86 can drive the support plate 85 to reset when the telescopic cylinder 5 is extended. Through the mutual cooperation of the telescopic cylinder 5 and the servo motor 7, the staff only needs to fix the sewing machine accessories on the limit component 87 away from the side of the mounting plate 2, and the servo motor 7 can drive it to automatically rotate to the bottom of the grinding belt 4, and then cooperate with the telescopic cylinder 5 to drive the lifting movement of the top seat 6, thereby reducing the chance of manual contact with moving parts during the grinding process, reducing the risk of injury to operators, and improving the safety of equipment operation;

[0043] When fixing the sewing machine accessories by the limiting component 87, the operator places the sewing machine accessories on the surface of the fixing platform 871 in the limiting component 87, and then rotates the knob 875 to drive the clamping block 874 and the forward and reverse screw rods 872 to rotate in the fixing platform 871. Then, the limiting block 873 slides toward or in the opposite direction along the inner wall of the fixing platform 871, thereby limiting the horizontal position of the accessories according to the specific size of the accessories.

[0044] When the limiting component 87 moves upward following the support plate 85, the connecting frame 878 gradually moves upward, and at this time, its bottom contacts the right-angled side of the top of the right-angle plate 89. At this time, under the elastic force of the elastic telescopic cylinder 88, the right-angle plate 89 can pull the limiting clamping plate 876 downward through the connecting frame 878, so that the spring sheet 877 is elastically deformed by the force, and at the same time, the limiting clamping plate 876 is clamped on the surface of the clamping block 874, thereby limiting the rotation of the clamping block 874 and the forward and reverse screw rods 872, and preventing the grinding belt 4 from slipping when contacting the sewing machine accessories;

[0045] At the same time, when the support plate 85 is displaced to the bottom of the grinding belt 4, the protrusion on the outside of the support plate 85 just rests on the bottom of the shift plate 99 in the synchronization assembly 9. At this time, as the support plate 85 gradually moves upward, the shift plate 99 gradually drives the push rod 98 to move upward, and then squeezes the hydraulic oil in the oil guide cylinder 97 into the oil storage cylinder 96. At this time, as the hydraulic oil in the oil storage cylinder 96 gradually increases, the piston rod 95 gradually drives the connecting plate 94 to move downward along the fixed column 91. At this time, the connecting plate 94 can press the limit plate 92 downward through the compression spring 93 to ensure that the friction between the grinding belt 4 and the sewing machine accessories is stable, thereby improving the grinding effect and quality.

[0046] Among them, the maximum sliding limit of the limit plate 92 is limited by the mounting plate 2. When the limit plate 92 runs to the lower dead point, as the support plate 85 continues to move upward, the piston rod 95 simultaneously drives the connecting plate 94 to move downward continuously, forcing the compression spring 93 to be further compressed, thereby enabling it to play a role in overload protection.
