[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example

[0035] like Figure 1-5As shown, this embodiment discloses a surface grinding device for processing double-ended studs, capable of removing burrs. It includes a work box 1 with an open rear structure for easy operation of the three-jaw chuck 13 to fix the double-ended studs. This also facilitates the replacement of the scraper plate 64 in the grinding mechanism 6 according to the size of the double-ended studs, allowing the device to grind different types of double-ended studs. A transparent observation window 2 is provided at the rear of the work box 1 for real-time observation of the grinding process. A first insertion slot is provided in the middle of the left side wall of the work box 1. Inside the first insertion slot is a second limiting mechanism 5 for restricting the position of the double-ended studs. The second limiting mechanism 5 can be replaced according to the size and type of the double-ended studs. A second motor 7 is provided at the front left end. The output end of the second motor 7 extends into the inner cavity of the work box 1 and is provided with a rotating wheel 71. A rotating ring 12 located outside the insertion slot 1 is provided in the middle of the left inner wall of the work box 1. A belt 17 is provided between the outer surface of the rotating ring 12 and the outer surface of the rotating wheel 71. The second motor 7 drives the rotating ring 12 and the double-ended bolt to rotate through the rotating wheel 71 and the belt 17 to grind the double-ended bolt evenly. A three-jaw chuck 13 is provided at the right end of the rotating ring 12 for fixing the double-ended bolt. The three-jaw chuck 13 is one of the common machine tool accessories. It consists of a chuck body, movable jaws and jaw drive mechanism. The double-ended bolt is positioned and clamped by controlling the three movable jaws to move radially on the chuck body.

[0036] For details, please refer to Figure 2 The right side wall of the work box 1 is provided with a limiting mechanism 4 to limit the length of the double-ended bolt extending into the work box 1, so that the end point of the thread on the surface of the double-ended bolt is directly aligned with the scraping plate 64, avoiding the scraping plate 64 from pressing against the other parts of the double-ended bolt and causing unnecessary grinding to the double-ended bolt, thereby reducing the adjustment time of the double-ended bolt and improving work efficiency. The upper right end of the work box 1 is provided with a motor 3, and the output end of the motor 3 is provided with a lead screw 31 through a coupling. The left end of the lead screw 31 passes through the right side wall of the work box 1 and is rotatably connected to the left inner wall of the work box 1. The outer surface of the lead screw 31 is provided with a grinding mechanism 6 that is slidably connected to the top wall of the work box 1, so that the grinding mechanism 6 can move horizontally with the rotation of the lead screw 31, and grind the double-ended bolt in conjunction with the rotation of the double-ended bolt.

[0037] For details, please refer to Figure 3The grinding mechanism 6 includes a movable block 61 threadedly connected to the lead screw 31. By pre-setting the rotational speed of the lead screw 31, the movable block 61 moves at a speed adapted to the rotational speed of the double-ended bolt, removing burrs from the double-ended bolt along its helical trajectory. A second insertion groove 62 is provided in the lower center of the movable block 61. Two springs 622 are provided on the top wall of the second insertion groove 62. The lower ends of the two springs 622 are slidably connected to a pressing plate 621 within the second insertion groove 62, used to push the scraping plate 64 downwards to press against the double-ended bolt. The lower part of the front and rear inner sidewalls of the second insertion groove 62... A locking groove and a limiting groove 1 that penetrates the rear end of the moving block 61 are provided. A magnet 2 632 is provided on the inner wall of the front side of the locking groove. A baffle 2 63 is provided inside the limiting groove 1 and the locking groove to prevent the scraping plate 64 from being pushed out of the locking groove 2 62 by the pressing plate 621 and the spring 1 622 after it is detached from the double-headed bolt. A magnet 1 631 is provided at the front end of the baffle 2 63 to attract the magnet 2 632. The magnet 1 631 and the magnet 2 632 attract each other to restrict the baffle 2 63 within the locking groove and the limiting groove 1, so as to prevent the baffle 2 63 from being thrown out during the rapid movement of the moving block 61.

[0038] Specifically, the bottom of the insertion slot 62 is provided with a scraping plate 64 that is close to the lower end of the extrusion plate 621. The scraping plate 64 removes the burrs on the spiral part of the double-ended bolt by closely adhering to the rotating double-ended bolt and moving horizontally. In addition, since the double-ended bolt has high rigidity, it is difficult for excessive grinding to occur due to excessive extrusion by the scraping plate 64. Furthermore, the device of this invention is mainly used to process common, low-cost double-ended bolts, which do not have the same precision requirements as bolts on professional equipment. Therefore, even if a small amount of excessive grinding occurs, it will not affect the normal use of the double-ended bolt. The middle of the scraping plate 64 is provided with a through groove 641 that runs through both its front and rear ends. The width of the through groove 641 is equal to the width of the limiting groove and the snap-fit ​​groove. The lower front end of the scraping plate 64 is provided with a support rod 65. The support rod 65 is mainly used to change the position and height of the scraping plate 64, so that the scraping plate 64 can move back to the initial position to perform repeated grinding on the double-ended bolt.

[0039] Specifically, the bottom of the scraper plate 64 has a wave-shaped structure that matches the thread on the surface of the double-ended bolt, which is used to grind the burrs on the surface of the spiral part of the double-ended bolt clean, and scrape off the residual debris left on the inner wall of the spiral part.

[0040] For details, please refer to Figure 2 and Figure 4-5The upper part of the front inner wall of the workbox 1 is provided with a lifting mechanism 11 for assisting the retraction of the grinding mechanism 6. The lifting mechanism 11 includes a lifting plate 111 and an inclined plate 113 fixedly connected to the front inner wall of the workbox 1. The inclined plate 113 is inclined with the left side lower and the right side higher. The right end of the lifting plate 111 is provided with a rotating plate 112. A portion of the rotating plate 112 away from the lifting plate 111 is inclined and rests on the inclined plate 113, so that when the support rod 65 moves to the right with the scraping plate 64, it will move in the right-sloping upward direction under the guidance of the inclined plate 113. Move the rotating plate 112 placed on the inclined plate 113, and then control the screw 31 to reverse so that the moving block 61, the scraping plate 64 and the support rod 65 start to move to the left. Then, the support rod 65 moves to the left and upward under the guidance of the rotating plate 112 so that the support rod 65 moves onto the lifting plate 111. At this time, the bottom of the scraping plate 64 is above the double-headed bolt. Finally, when the support rod 65 is disengaged from the lifting plate 111, the wavy structure at the bottom of the scraping plate 64 is just engaged at the end point of the spiral part of the double-headed bolt.

[0041] Specifically, when the scraper plate 64 is pressed against the double-ended bolt, the support rod 65 is located below the lowest part of the lifting plate 111, meaning that the lifting plate 111 will not affect the normal rightward movement of the support rod 65. When the scraper plate 64 leaves the double-ended bolt, the support rod 65 is located above the lowest part of the inclined plate 113, meaning that the support rod 65 will move to the right and come into contact with the inclined plate 113, and then move diagonally upward under the guidance of the inclined plate 113, so that the scraper plate 64 can move back above the double-ended bolt.

[0042] For details, please refer to Figure 2 and Figure 4 The upper right side wall of the work box 1 is provided with a moving groove 2 14 that penetrates the side wall of the work box 1. The bottom wall of the moving groove 2 14 is provided with a through groove 2 15 that penetrates the left and right ends of the right side wall of the work box 1. The width of the through groove 2 15 is smaller than the width of the moving groove 2 14. A U-shaped slot is provided in the middle of the inner wall of the through groove 2 15.

[0043] Specifically, the limiting mechanism 4 includes a slidably connected rod 41 in the through groove 15. The left end of the rod 41 is provided with a rotating disk 42 to avoid excessive wear on the double-ended bolt. Because the rotating disk 42 is rotatably connected to the left side of the rod 41, the rotating disk 42 will rotate with the double-ended bolt due to its close contact with it. The right side of the outer surface of the rod 41 is provided with multiple baffles 44 that are slidably connected to the U-shaped slot and the moving groove 14. The limiting mechanism 4 limits the length of the double-ended bolt extending into the work box 1 by engaging different baffles 44 in the U-shaped slot, so that the termination point of the spiral part of the double-ended bolt of different models and sizes can always be aligned with the scraping plate 64, thereby reducing the adjustment process and time and improving work efficiency.

[0044] Specifically, the outer surfaces of the multiple baffles 44 are coated with different colored paints, making it easy to identify which baffle 44 is used for which type of double-ended bolt, thereby simplifying the operation steps and speeding up the operation for beginners. Example

[0045] This embodiment, based on embodiment one, adds a limiting mechanism 25 to reduce the adjustment time of the double-ended bolt and accelerate the removal of burrs at the spiral position of the double-ended bolt. Figure 6-10 As shown, the limiting mechanism 2 5 includes a plug-in post 52 located in the plug-in slot. The left end of the plug-in post 52 is provided with an L-shaped mounting plate 51 that is tightly attached to the left end of the work box 1. The L-shaped mounting plate 51 and the plug-in post 52 are provided with a limiting groove 2 521 in the middle, so that the limiting mechanism 2 5 can be replaced according to the type and size of the double-ended bolt. The limiting groove 2 521 can initially limit the double-ended bolt at the center of the rotating ring 12 and the three-jaw chuck 13. The center line of the limiting groove 2 521 is on the same horizontal line as the center line of the rotating ring 12 and the three-jaw chuck 13, so that after the double-ended bolt is inserted into the work box 1, it will directly abut against the rotating disk 42 and avoid misalignment with the rotating disk 42.

[0046] For details, please refer to Figure 7-8 A wedge 54 is provided at the lower middle of the horizontal part of the L-shaped mounting plate 51. A partition 541 is provided on the outer surface of the wedge 54. A spring 542 wrapped around the outside of the wedge 54 is provided between the upper end of the partition 541 and the lower end of the horizontal part of the L-shaped mounting plate 51. When the spring 542 is in the normal state, the bottom of the wedge 54 is located inside the end point of the spiral position on the other side of the double-headed bolt. The upper end of the wedge 54 extends to the upper side of the L-shaped mounting plate 51 and is provided with a baffle 544. A water storage membrane sleeve 512 is provided between the lower inner side of the baffle 544 and the upper end of the L-shaped mounting plate 51. The water storage membrane sleeve 512 is sleeved on the outside of the wedge 54 and together with the upper end of the L-shaped mounting plate 51 and the lower end of the baffle 544, forms a closed water storage space.

[0047] For details, please refer to Figure 8-9The L-shaped mounting plate 51 has a water storage tank 511 located outside the shank 54 inside its horizontal section. The water storage tank 511 is filled with water. Water passage holes 514 penetrating the upper end of the L-shaped mounting plate 51 are provided on the top left and top wall right of the water storage tank 511. Water passage channels 515 penetrating the upper end of the L-shaped mounting plate 51 are provided on the front and rear top walls of the water storage tank 511. The diameter of the water passage channels 515 is much larger than the diameter of the water passage holes 514, allowing water in the water storage tank 511 to quickly flow into the inside of the water storage membrane sleeve 512 through the water passage channels 515. Water inside the water storage membrane sleeve 512, however, can only slowly flow back into the water storage tank 511 through the water passage holes 514. The water passage channels 515 are located inside the water storage membrane sleeve 512. A magnetic ring 518 is provided on the upper part of the inner surface of the groove 515. The upper end of the L-shaped mounting plate 51 is provided with two sets of limiting components 517 located on the outside of the two water passage grooves 515 respectively. The limiting component 517 consists of four limiting rods to prevent the sealing plate 516 from being directly washed away by water. The outer surface of the limiting component 517 is provided with a sealing plate 516 with a magnetic structure. The sealing plate 516 opens or closes the water passage groove 515 by sliding the limiting component 517. The sealing plate 516 and the magnetic ring 518 attract each other. The outer surface of the part of the bar 54 located in the water storage groove 511 is provided with a lifting plate 543 that is slidably connected in the water storage groove 511. When the bar 54 moves upward, it will drive the lifting plate 543 to move upward and push the water to the inside of the water storage membrane sleeve 512.

[0048] For details, please refer to Figure 7 and Figure 9 The horizontal portion of the L-shaped mounting plate 51 has two moving grooves 513 that penetrate the side wall of the L-shaped mounting plate 51. The interior of each of the two moving grooves 513 is provided with an L-shaped push plate 55 extending to the bottom of the moving groove 513. That is, the vertical portion of the L-shaped push plate 55 is slidably connected in the moving groove 513, while the horizontal portion is located below the horizontal portion of the L-shaped mounting plate 51. The two L-shaped push plates 55 are located directly below the baffle 3 544. That is, the length of the baffle 3 544 is greater than the distance between the vertical portions of the two L-shaped push plates 55, so that the L-shaped push plates 55 can move upward under the action of the spring 2 551 to raise the baffle 3 544 and the stick 54. The upper end of the horizontal portion of each of the two L-shaped push plates 55 is provided with two spring 2 551 between the lower end of the horizontal portion of the L-shaped mounting plate 51. The middle of the lower end of each of the two L-shaped push plates 55 is provided with a fixed pulley 56.

[0049] For details, please refer to Figure 10The upper inner surface of the limiting groove 521 has a receiving groove 53. The upper inner side of the vertical portion of the L-shaped mounting plate 51 has two mounting grooves 523 and two receiving grooves 522, all symmetrically distributed about the center line of the limiting groove 521. The receiving groove 522 has a rotating shaft 527 inside. The outer surface of the rotating shaft 527 is provided with a winding roller 528, and the outer surface of the winding roller 528 is provided with a pull rope 57. The end of the pull rope 57 away from the winding roller 528 passes through the left end of the vertical part of the L-shaped mounting plate 51 and is fixedly connected to the lower end of the L-shaped push plate 55. When connecting the L-shaped push plate 55 and the winding roller 528, the pull rope 57 also passes around the outside of the fixed pulley 56, so that when the winding roller 528 winds up the pull rope 57, it can directly pull the L-shaped push plate 55 downward. The rotating shaft 527 is close to the outside of the fixed pulley 56. One end of the mounting groove 523 extends into the mounting groove 523 and is equipped with a second gear 529. The left side of the inside of the second storage groove 53 is equipped with a first rotating shaft 524. The outer surface of the first rotating shaft 524 is equipped with a rotating plate 525 extending to the outside of the second storage groove 53. A part of the rotating plate 525 away from the first rotating shaft 524 extends into the second limiting groove 521 so that the rotating plate 525 can be pushed and flipped into the second storage groove 53 by the double-headed bolt inserted into the second limiting groove 521. The two ends of the first rotating shaft 524 extend into the mounting groove 523 on the same side and are equipped with a first gear 526 that meshes with the second gear 529. So that when the rotating plate 525 is pushed and flipped by the double-headed bolt, it will also drive the second gear 529 to rotate together through the first gear 526, thereby driving the roller 528 to rotate and wind up the pull rope 57, pulling the L-shaped push plate 55 to move down, thereby allowing the stick 54 to move down slowly and position the double-headed bolt.

[0050] Specifically, the sum of the elastic forces of the four springs 551 is greater than the elastic force of the spring 542, so that the baffle 544 can be lifted by the two L-shaped push plates 55 in its natural state, thereby moving the spur bar 54 upward and avoiding obstruction of the double-headed bolt insertion into the limiting groove 521.

[0051] Specifically, the number of teeth on the surface of gear 526 is greater than the number of teeth on the surface of gear 529, so that the mounting groove 523 can drive the rotating shaft 527 and the roller 528 to rotate more times as the rotating shaft 524 and gear 526 rotate, thereby increasing the downward movement distance of the L-shaped push plate 55.

[0052] Therefore, the specific implementation method of this embodiment is as follows:

[0053] During the process of inserting the double-headed bolt into the limiting groove 521, the rotating plate 525 will also be pushed to make the rotating plate 525 flip into the storage groove 53. Then the rotating plate 525 drives the gear 526 to rotate through the rotating shaft 524. The gear 526 then drives the roller 528 to rotate more times through the gear 529 and the rotating shaft 527, which winds up the pull rope 57, thereby pulling the L-shaped push plate 55 to move down and canceling the pushing force on the baffle 544.

[0054] Then, under the action of spring 542, baffle 3 544 squeezes the water flow inside the water storage membrane sleeve 512 back into the water storage tank 511 through the water passage 514, so that the wedge 54 can slowly move down. After the double-ended bolt is pressed against the rotating disk 42, baffle 3 544 is pressed down to accelerate the downward movement of the wedge 54 so that the wedge 54 is pressed against the double-ended bolt. Then, the double-ended bolt is manually controlled to rotate slowly until obvious resistance is felt. At this time, the end point of the spiral part of the double-ended bolt is facing upward, so that the subsequent scraping plate 64 can directly enter the inner side of the corresponding spiral part of the double-ended bolt when it moves down, reducing the adjustment time of the double-ended bolt and speeding up the work efficiency. Finally, the double-ended bolt is fixed by the three-jaw chuck 13, and then the wedge 54 is manually pulled up to separate the wedge 54 from the double-ended bolt to avoid affecting the rotation of the double-ended bolt.
