Description

Technical Field

[0001] This application relates to the field of grinding equipment technology, and in particular to a flat grinding machine for processing disc springs. Background Technology

[0002] Disc springs are special springs that are tapered in the axial direction and bear loads. During their production, the blank (ring-shaped metal sheet) of the disc spring is first ground using a flat grinding machine to ensure that it has high precision in parallelism, flatness and surface roughness.

[0003] In some existing surface grinding equipment, several rough blanks are first placed circumferentially on the surface of a truncated cone and fixed by an electromagnet. Then, the truncated cone drives the rough blanks to rotate. At this time, the grinding wheel approaches the upper surface of the rough blank and performs surface grinding on that surface. Simultaneously, the spray pipe sprays grinding fluid into the position between the grinding wheel and the rough blank. After the surface grinding of one side of the rough blank is completed, the rough blank is rotated halfway around to perform surface grinding on the other side of the rough blank. Through the above actions, the surface grinding operation of the disc spring rough blank is completed.

[0004] However, during the process of the grinding fluid rinsing the area between the grinding wheel and the rough blank, some of the debris generated by the surface grinding will adhere to the surface of the grinding wheel through the liquid. As the grinding wheel rotates, it will come into contact with the rough blank again, causing fine scratches to easily appear on the surface of the rough blank, thus affecting the surface grinding quality of the disc spring. Summary of the Invention

[0005] This application proposes a surface grinding device for processing disc springs, which has the advantage of reducing the amount of debris carried by the grinding wheel that comes into secondary contact with the disc spring blank, thereby solving the problem that the surface grinding quality of the blank is affected by the contact of debris carried by the grinding wheel with the disc spring blank.

The slide rod is fixedly installed in the first slide groove. The connecting plate and the slide rod are slidably connected.

A connecting rod is positioned between the turntable and the connecting plate. One end of the connecting rod is eccentrically hinged to the circular surface of the turntable, and the other end of the connecting rod is hinged to the connecting plate. Motor No. 2 is fixedly installed on one side of the socket, corresponding to the position of the turntable. The output shaft of Motor No. 2 extends into the first slide groove and forms a fixed connection with the center position of the turntable.

[0008] Furthermore, the interior of the extended shell is provided with a wetting mechanism, the wetting mechanism comprising: The pump housing is fixedly installed inside the extended housing and located on the side of the roller away from the grinding wheel; The liquid pump tank has a replenishment port on the outer wall of the extended housing, and the replenishment port is connected to the equipment for recovering grinding fluid; The liquid pump box's spray nozzle passes through the cylindrical shell and faces the roller.

[0009] Furthermore, the socket, plug, comb teeth, first slide groove, slide rod, connecting plate, turntable, connecting rod and second motor are all set at an inclined angle. The upper end of the comb teeth is inclined towards the grinding wheel, and there is a distance in millimeters between the upper end of the comb teeth and the arc surface of the roller.

[0010] Furthermore, the brush body is made of hydrophilic hollow fiber bristles, and the comb teeth are made of polyurethane elastic comb plates with rounded edges.

[0011] Furthermore, a cover is fixedly installed on the outside of the socket, a mesh is fixedly installed at the bottom of the cover with bolts, and a waterproof shell is fixedly sleeved on the outside of the second motor.

[0012] Furthermore, the bottom wall of the extended housing has a longitudinally penetrating opening on the side away from the grinding wheel, with the lower end of the opening facing the space between the frustum and the baffle, and the bottom wall of the extended housing is inclined towards the opening.

[0013] Furthermore, the plug-in has a second sliding groove inside, and a slider is slidably engaged inside the second sliding groove.

[0014] This application has the following beneficial effects: This application provides a surface grinding device for processing disc springs. Through the arrangement of a cleaning mechanism and a combing mechanism, the rotating brush body contacts the working surface of the grinding wheel, causing the debris adhering to the working surface of the grinding wheel to be wiped away by the brush body. This reduces the amount of debris on the grinding wheel surface that comes into secondary contact with the workpiece, thereby improving the surface grinding quality of the disc spring. Subsequently, the downward rotating brush body contacts the comb teeth, causing the impurities attached to the brush body to be scraped off, preventing the brush body from circulating with slag, ensuring that it is in a clean state every time it contacts the grinding wheel, reducing scratches on the surface of the disc spring blank due to secondary contact, and reducing the impact on the surface grinding quality of the blank.

[0015] By incorporating a cleaning mechanism and an immersion mechanism, after the brush body passes through the comb teeth, the spray nozzle sprays clean grinding fluid onto the brush body, causing residual debris on the brush body to be washed away, thereby further maintaining the cleanliness of the brush body and reducing the impact of secondary contact of debris on the surface grinding quality of the disc spring blank. Subsequently, when the brush body carrying grinding fluid contacts the upper side of the grinding wheel, the liquid wets the gap between the abrasive grains of the grinding wheel, enhancing the removal effect on debris, thereby further reducing the impact of secondary contact of debris on the surface grinding quality of the disc spring blank.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] Example 1: Please refer to Figures 1-5A surface grinding machine for processing disc springs includes a worktable 1. A frustum 2 is fixedly mounted on the upper surface of the worktable 1. An electromagnet and a rotating assembly are installed inside the frustum 2 to fix the rough blank and realize its revolution. A baffle 3 is provided on the outer side of the frustum 2. The space between the frustum 2 and the baffle 3 is used to collect grinding fluid and debris. A mounting platform 4 is fixedly mounted on the upper surface of the worktable 1 and located behind the frustum 2. A grinding wheel 5 is rotatably mounted inside the mounting platform 4. A spray pipe 6 is fixedly mounted on one side of the mounting platform 4, with the output end of the spray pipe 6 facing the lower part of the grinding wheel 5. An extension shell 7 is fixedly mounted on the side of the mounting platform 4 away from the spray pipe 6. A cleaning mechanism 8 is provided inside the extension shell 7. The cleaning mechanism 8 includes a cylindrical shell 80, a roller 81, and a brush 8. 2. A first motor 83 and a cylindrical shell 80 are fixedly installed inside an extended shell 7. A roller 81 is rotatably installed inside the cylindrical shell 80. Brushes 82 are fixedly installed at equal intervals on the circumferential side of the roller 81. The rotation path of the brushes 82 partially coincides with that of the grinding wheel 5. A first motor 83 is fixedly installed on the side of the extended shell 7 facing away from the truncated cone 2. The output end of the first motor 83 is fixedly connected to the roller 81. A combing mechanism 9 is provided in the inner cavity of the extended shell 7 and below the cleaning mechanism 8. The combing mechanism 9 includes a socket 90, an insert 91, and comb teeth 92. The socket 90 is fixedly installed below the brushes 82. The insert 91 is installed inside the socket 90. Comb teeth 92 are fixedly installed at equal intervals on the side of the insert 91 facing the brushes 82. The comb teeth 92 are inserted into the brushes 82.

[0021] In use, the disc spring blank is placed circumferentially on the surface of the frustum 2 and fixed by an electromagnet. Then, the frustum 2 drives the blank to rotate. At this time, the mounting platform 4 drives the grinding wheel 5 to rotate counterclockwise and approach the upper surface of the blank, thereby performing a surface grinding process. Simultaneously, the spray pipe 6 sprays grinding fluid into the position between the grinding wheel 5 and the blank, thereby cooling the position and flushing the generated debris into the space between the frustum 2 and the baffle 3 (achieving separation of debris and grinding fluid, and recycling and reusing the grinding fluid). During this process, the first motor 83 drives the roller 81 and the brush body 82 to rotate counterclockwise, so that the brush body 82 contacts the working surface of the grinding wheel 5, causing the debris adhering to the working surface of the grinding wheel 5 to be wiped away by the brush body 82, thereby reducing the amount of debris on the surface of the grinding wheel 5 contacting the disc spring blank a second time, making the surface of the blank less prone to scratches, thereby improving the surface grinding quality of the disc spring. Afterwards, the rotating brush body 82 contacts the comb teeth 92 downwards, so that the impurities attached to the brush body 82 are scraped off by the comb teeth 92, preventing the brush body 82 from carrying slag and ensuring that it is clean each time it contacts the grinding wheel 5. This reduces the scratches on the surface of the disc spring blank caused by secondary contact and reduces the impact on the surface grinding quality of the blank. After the surface grinding of one side of the blank is completed, the blank is rotated half a circle to grind the other side of the blank. Through the above actions, the single surface grinding operation of the disc spring blank is completed.

[0022] To further remove debris from brush body 82, please refer to [link / reference needed]. Figures 1-5 The combing mechanism 9 also includes a first slide groove 93, a slide rod 94, a connecting plate 95, a turntable 96, a connecting rod 97, and a second motor 98. A first slide groove 93 is provided inside the socket 90, on the side of the insert 91 facing away from the brush body 82. The slide rod 94 and the connecting plate 95 are installed in the first slide groove 93. The slide rod 94 is fixedly installed in the first slide groove 93. The connecting plate 95 is slidably connected to the slide rod 94. The side of the connecting plate 95 facing the insert 91 is fixedly connected to the insert 91. The insert 91... A turntable 96 is rotatably mounted in the inner cavity of the first slide groove 93, forming a sliding engagement with the socket 90. A connecting rod 97 is provided between the turntable 96 and the connecting plate 95. One end of the connecting rod 97 is eccentrically hinged to the circular surface of the turntable 96, and the other end of the connecting rod 97 is hinged to the connecting plate 95. A second motor 98 is fixedly mounted on one side of the socket 90, corresponding to the position of the turntable 96. The output shaft of the second motor 98 extends into the first slide groove 93 and is fixedly connected to the center position of the turntable 96.

[0023] During the process of the brush body 82 rotating to brush the working surface of the grinding wheel 5 to remove debris, the second motor 98 drives the turntable 96 to rotate, causing the connecting rod 97 to drive the connecting plate 95, the plug 91 and the comb teeth 92 to move back and forth slightly. Then, when the brush body 82 contacts the comb teeth 92, the reciprocating comb teeth 92 will cause the brush body 82 to vibrate, thereby causing the debris on the brush body 82 to fall further downward. At the same time, the shaking action of the brush body 82 causes the grinding waste fluid adhering to the brush body 82 to be shaken off simultaneously, preventing the grinding fluid from carrying debris to stick to the brush body 82, thereby further improving the cleanliness of the brush body 82.

[0024] To enhance the removal effect of brush body 82 on the surface of grinding wheel 5, please refer to [link / reference needed]. Figures 1-5 The interior of the extended housing 7 is provided with an impregnation mechanism 10, which includes a liquid pump box 100, a liquid replenishment port 101 and a liquid spraying port 102. The liquid pump box 100 is fixedly installed in the inner cavity of the extended housing 7 and on the side of the roller 81 away from the grinding wheel 5. The liquid replenishment port 101 of the liquid pump box 100 is opened on the outer wall of the extended housing 7 and is connected to the equipment for recovering grinding fluid. The liquid spraying port 102 of the liquid pump box 100 passes through the cylindrical housing 80 and faces the roller 81.

[0025] After the rotating brush body 82 passes the comb teeth 92, the liquid pump box 100 draws the recovered clean grinding fluid through the replenishment port 101 and sprays the clean grinding fluid onto the brush body 82 through the spray port 102, which causes the residual debris on the brush body 82 to be washed away, thereby further maintaining the cleanliness of the brush body 82, reducing the amount of debris that comes into secondary contact with the rough blank with the grinding wheel 5, and reducing the impact on the surface grinding quality of the disc spring rough blank. Subsequently, when the brush body 82 carries the grinding fluid to contact the upper side of the grinding wheel 5, the fluid wets the gap between the abrasive grains of the grinding wheel 5, enhancing the chip removal effect and thus further reducing the impact of secondary chip contact on the surface grinding quality of the disc spring blank. Meanwhile, the grinding fluid wets the brush body 82, which reduces aging and breakage caused by dry friction of the bristles. In addition, when the brush body 82 containing grinding fluid is scraped by the comb teeth 92, it will reduce the combing resistance and make the debris scraping action smoother.

[0026] To reduce the frictional resistance between debris and brush body 82, please refer to... Figures 1-5 The socket 90, plug 91, comb teeth 92, first slide groove 93, slide rod 94, connecting plate 95, turntable 96, connecting rod 97 and second motor 98 are all set at an inclined angle. The upper end of the comb teeth 92 is inclined towards the grinding wheel 5. There is a gap in millimeters between the upper end of the comb teeth 92 and the arc surface of the roller 81.

[0027] By tilting the brush teeth 92, when they are inserted into the brush body 82, they will first pass through the root of the brush body 82, thereby increasing the contact area between the brush teeth 92 and the brush body 82, increasing the amount of debris scraped by the brush teeth 92, increasing the cleanliness of the brush body 82, and thus reducing the impact of secondary contact of debris on the surface grinding quality of the disc spring blank. Meanwhile, the combing direction of the comb teeth 92 is consistent with the direction from the root to the tip of the brush body 82, thereby reducing the frictional resistance between the debris and the brush body 82 and reducing the probability that the debris is scraped but does not fall off. In addition, after combing, the bristles stand upright with no residue at the roots, which allows the sprayed grinding fluid to penetrate into the brush body 82 more smoothly, thereby improving the uniformity of the fluid retention in the brush body 82 and avoiding the effect of fluid retention due to debris residue.

[0028] To increase the water capacity of the brush body 82, the brush body 82 is made of hydrophilic hollow fiber bristles (such as nylon 66 hollow filaments), and the comb teeth 92 are made of polyurethane elastic comb plates (Shore A 70-80 hardness) with rounded edges (radius 1mm).

[0029] Hydrophilic hollow fiber bristles have a higher water retention capacity than ordinary solid bristles, which makes the brush body 82 smoother when it comes into contact with the comb teeth 92, thereby reducing the frictional resistance between debris and the brush body 82 and reducing the probability that debris is scraped but does not fall off. By setting the comb teeth 92 as described above, the hard friction between the comb teeth 92 and the brush body 82 is reduced, thereby reducing the frictional damage to the brush body 82.

[0030] To achieve separation of chips and grinding fluid, please refer to [link / reference]. Figures 1-5 A retaining cover 11 is fixedly installed on the outside of the socket 90, and a mesh 12 is fixedly installed on the bottom of the retaining cover 11 by bolts. A waterproof shell is fixedly sleeved on the outside of the second motor 98.

[0031] With the above settings, the debris scraped off by the comb teeth 92 will fall onto the mesh 12, while the scraped grinding fluid will pass through the mesh 12, thereby achieving separation of the two. Meanwhile, the No. 2 motor 98 and the waterproof shell block part of the area above the partition 12, leaving the corresponding part of the partition 12 exposed. This makes it easier for the grinding fluid to pass through the above-mentioned area as the debris continues to fall, thereby further achieving the separation of the two.

[0032] To achieve grinding fluid recovery, please refer to [link / reference]. Figures 1-5 An opening 13 is longitudinally provided on the bottom wall of the extended housing 7 and on the side away from the grinding wheel 5. The lower end of the opening 13 faces the space between the frustum 2 and the baffle 3, and the bottom wall of the extended housing 7 is inclined in the direction of the opening 13.

[0033] By setting the opening 13, the grinding fluid that passes through the mesh 12 will fall into the space between the frustum 2 and the baffle 3 through the opening 13, thereby realizing the recycling of the grinding fluid.

[0034] Example 2: Please refer to Figures 1-6 The plug-in 91 has a second slide groove 14 inside, and a slider 15 is slidably engaged inside the second slide groove 14. There is space between the two ends of the slider 15 and the inner wall of the second slide groove 14 in the corresponding direction. A contact rod 16 is fixedly installed at both ends of the slider 15. The end of the contact rod 16 facing away from the slider 15 slides out of the plug-in 91 and abuts against the inner wall of the socket 90. A spring 17 is sleeved on the outside of the contact rod 16. One end of the spring 17 is fixedly connected to the slider 15, and the other end of the spring 17 is fixedly connected to the inner wall of the plug-in 91. The comb teeth 92 are divided into moving teeth 920 and stationary teeth 921. The moving teeth 920 and stationary teeth 921 are alternately and equidistantly arranged. The end of the moving teeth 920 facing the plug-in 91 extends into the second slide groove 14 and is fixedly connected to the slider 15. The end of the stationary teeth 921 facing the plug-in 91 is fixedly connected to the plug-in 91. There is always a gap between the moving teeth 920 and the stationary teeth 921.

[0035] During the process of the turntable 96 driving the comb teeth 92 to move back and forth in a small amplitude, the plug 91 will move synchronously, thereby squeezing the contact rod 16 in the corresponding direction, causing the contact rod 16 to extend further into the second slide groove 14 and stretch the corresponding spring 17, so that the slider 15 drives the moving tooth 920 to approach the stationary tooth 921 in the moving direction, thereby reducing the distance between the two. Through this action, during the process of the comb teeth 92 extending into the brush body 82, the moving tooth 920 and the stationary tooth 921 will squeeze the bristles between them in a small amplitude, thereby causing the grinding fluid and debris on the bristles to fall off, thereby increasing the cleanliness of the brush body 82, and thus reducing the impact of secondary contact of debris on the surface grinding quality of the disc spring blank.
