[0002] A grinding wheel, also known as a bonded abrasive, is a type of abrasive tool in which ordinary abrasive grains are bonded together with a bonding agent to form a specific shape and possess a certain strength. It generally consists of abrasive grains, a bonding agent, and pores; these three parts are often referred to as the three essential elements of a bonded abrasive tool. Based on the type of bonding agent used, common types include ceramic (bonded) grinding wheels, resin (bonded) grinding wheels, and rubber (bonded) grinding wheels.

[0056] Reference Figure 1 and Figure 3 This application provides a multi-size grinding wheel processing apparatus, including:

[0057] The pressure mechanism 1 includes a worktable 11, a lifting assembly 12, a first sliding assembly 13, an upper die, a first lower die 14, a second lower die 15, and a press.

The first lower die 14 is slidably connected to the worktable 11 through the first sliding assembly 13. The second lower die 15 is located below the first sliding assembly 13 and is connected to the worktable 11 through the lifting assembly 12.

[0058] Sliding mechanism 2 is mounted next to pressure mechanism 1; the sliding mechanism 2 can be an electric slide module, which includes an electric slider and a metal slide rail, with the electric slider slidably connected to the metal slide rail.

[0059] Telescopic mechanism 3 is installed on the sliding end of sliding mechanism 2; the telescopic mechanism 3 is an electric telescopic rod, which is vertically installed at the lower part of electric slider.

[0060] The laying mechanism 4 is installed at the lower part of the electric telescopic rod and is used to lay the grinding wheel processing raw materials on the multiple lower molds 14;

[0061] The feeding mechanism 5 is installed on the laying mechanism 4 and is used to feed the grinding wheel processing raw materials to the laying mechanism 4.

[0062] Reference Figures 3 to 6 The laying mechanism 4 includes a support component 41, two second sliding components 42, a rotating cylinder 43, a driving component 44, and a laying component 45;

[0063] In this embodiment, the support assembly 41 includes a support frame 411 and a support member 412. The support frame 411 is installed at the lower part of the electric telescopic rod, and the support member 412 is installed at the lower part of the support frame 411. The support member 412 may be two vertical support rods or a support ring. The function of the support assembly 41 is to connect the two second sliding assemblies 42, the rotating cylinder 43, the drive assembly 44, and the flat assembly 45 to the lower part of the electric telescopic rod.

[0064] Two second sliding components 42 are vertically symmetrically arranged at the lower part of the support component 41, i.e., on the support member 412. The rotating cylinder 43 is rotatably connected between the sliding ends of the two second sliding components 42, i.e., rotatably connected between the two second sliders 422. The driving component 44 is installed on the sliding end of one of the second sliding components 42 and is used to drive the rotating cylinder 43 to rotate. The flattening component 45 is installed at the lower part of the rotating cylinder 43 and is used to lay the grinding wheel processing material on the inner bottom surface of the first lower mold 14 and the second lower mold 15.

[0065] The second sliding assembly 42 includes a second slide rail 421, a second slider 422, a stop block, and a spring. The second slide rail 421 is vertically installed on the lower part of the support assembly 41. The second slider 422 is slidably connected to the second slide rail 421. The stop block is fixedly installed on the upper part of the second slide rail 421 and is located above the second slider 422. One end of the spring is fixed to the lower end of the stop block, and the other end is fixed to the upper part of the corresponding second slider 422. The rotating cylinder 43 is rotatably connected between the two second sliders 422.

[0066] In this embodiment, the drive assembly 44 includes a motor, a first gear, and a second gear; the motor is mounted on the sliding end of one of the second sliding assemblies 42, the first gear is mounted on the output shaft of the motor, and the second gear is mounted on the outer ring of the rotating drum 43, with the first gear and the second gear meshing with each other;

[0067] Reference Figure 4 and Figure 5 In this embodiment, the tiling assembly 45 includes multiple tiling modules, an airbag 451, multiple connecting pipes, and a baffle 452. The multiple tiling modules are arranged in a circular array on the lower outer ring of the rotating drum 43. Each tiling module includes a sleeve rod 453, a toggle plate 454, a cylinder 4543, a piston 455, a connecting rod 4551, and a first tension spring 456. The sleeve rod 453 is mounted on the lower outer ring of the rotating drum 43. A second through hole is formed on the side of the sleeve rod 453 away from the rotating drum 43. The piston 455 is slidably connected within the second through hole. The cylinder 4543 is fitted onto the lower part of the rotating drum 43. One side of the moving plate 454 is mounted on the lower side of the sleeve rod 453 via the connecting rod 4551, and the other side is wound around the lower part of the outer ring of the rotating cylinder 43 and located inside the cylinder 4543. One end of the first tension spring 456 is fixedly connected to the inner wall of the second through hole near the rotating cylinder 43, and the other end is fixedly connected to the side wall of the piston 455. The actuating plate 454 is made of flexible material and can be a combination of spring plate and rubber plate, that is, spring plates on both sides and a rubber plate in the middle, all three are bonded together; or one side is a spring plate and the other side is a rubber plate, both are bonded together; or other.

[0068] The airbag 451 is rotatably connected to the lower part of the rotating cylinder 43. The baffle 452 is mounted on the inner wall of the rotating cylinder 43 and located above the airbag 451. One end of each of the multiple connecting pipes is connected to the airbag 451, and the other end is connected to the second through hole on each of the multiple flat modules.

[0069] An annular protrusion is provided at the middle position of the inner bottom surface of the first lower mold 14 and the second lower mold 15. The annular protrusion can be rotatably connected to the first lower mold 14 or the second lower mold 15 or fixedly connected. The outer diameter of the annular protrusion is smaller than the inner diameter of the rotating cylinder 43. In this embodiment, the working process of the flat assembly 45 is as follows:

[0070] By controlling the sliding mechanism 2 and the telescopic mechanism 3, the rotating drum 43 moves to directly above the first lower die 14 or the second lower die 15, and the rotating drum 43 abuts against the annular protrusion. The annular protrusion squeezes the airbag 451. Since the upper part of the airbag 451 is equipped with a baffle 452, the air in the airbag 451 will enter the corresponding second through hole through multiple connecting pipes, and push the piston 455 and the actuating plate 454 to slide towards the inner wall of the first lower die 14 or the second lower die 15 until they abut against the inner wall of the first lower die 14 or the second lower die 15. This structure allows the flat assembly 45 to be used for processing various sizes of grinding wheels without the need for separate control, resulting in a high degree of automation.

[0071] In this embodiment, the cross-sectional shape of the actuating plates 454 is a parallelogram, and they are all obliquely installed on the lower part of the rotating drum 43. A first oblique hole 4541 from bottom to top is formed on the side of the actuating plate 454 near the rotating drum 43, and a second oblique hole 4542 from top to bottom is formed on the side of the actuating plate 454 away from the rotating drum 43. Since the cross-sectional shape of the sleeve rod 453 and the actuating plates 454 are both parallelograms and they are obliquely installed on the lower part of the rotating drum 43, the motor is a servo motor capable of rotating in both forward and reverse directions. The drive assembly 44 drives the sleeve rod 453 and the actuating plates 454... When 54 rotates in the forward direction, the grinding wheel material on the inner bottom surface of the first lower die 14 or the second lower die 15 will slide along the direction of the second inclined hole 4542 on one side of the actuating plate 454, and can pass through the second inclined hole 4542 to enter the other side of the actuating plate 454. Then the motor drives the actuating plate 454 to rotate in the reverse direction, which can slide the grinding wheel material towards the direction of the first inclined hole 4541, and slide through the first inclined hole 4541 to the previous side. This method can improve the laying efficiency of the flat module, and at the same time make the grinding wheel material on the first lower die 14 or the second lower die 15 more evenly laid, which also further improves the processing quality of the grinding wheel.

[0072] In this embodiment, the feeding mechanism 5 includes a housing 51, a feeding pipe 52, a rotating shaft 53, a housing 54, a distributing cylinder 55, a ball limiting module 56, and a one-way drive assembly 57.

[0073] Reference Figures 6 to 10The housing 51 is installed next to the pressure mechanism 1. The rotating shaft 53 is laterally rotatably connected to the middle of the support assembly 41. The shell 54 is fixedly installed in the middle of the support assembly 41. The distributing cylinder 55 is cylindrical, and its outer ring has a circular array of multiple first distributing grooves 551 and multiple second distributing grooves 552. The first distributing grooves 551 and the second distributing grooves 552 are spaced apart. The distributing cylinder 55 is rotatably connected to the inner wall of the shell 54 and fits against the inner wall of the shell 54. The middle of the distributing cylinder 55 is fixedly connected to the rotating shaft 53. The upper part of the shell 54 has a feeding hole, and the conveying pipe 52 communicates with the feeding hole. The lower part of the shell 54 has a discharging hole. The discharge port can be fitted with a guide pipe to prevent the grinding wheel material from spilling. The distribution cylinder 55 can also have an vent hole with a diameter between 0.1 and 0.3 mm. The vent hole is connected to the first distribution groove 551 and the second distribution groove 552 to prevent the grinding wheel material from accumulating in the first and second distribution grooves under atmospheric pressure and being unable to be discharged through the discharge port. A sealing sleeve can be installed on the outer ring of the distribution cylinder 55 to prevent the grinding wheel material in the first and second distribution grooves 551 from mixing, or to prevent the distribution cylinder 552 and the housing 54 from being blocked by the grinding wheel material, thus preventing normal rotation between them. The sealing sleeve can be made of silicone or other materials.

[0074] The ball limiting module 56 is installed between the dispensing cylinder 55 and the housing 54 to position the dispensing cylinder 55; the one-way drive component 57 is installed in the middle of the laying mechanism 4 to drive the rotating shaft 53 to rotate.

[0075] The feeding mechanism 5 can also be equipped with a vibration module, which is installed on the housing 51 to make the housing 51 vibrate, so as to avoid the grinding wheel processing material from being blocked in the housing 51, causing the material conveying pipe 52 to be unable to deliver the grinding wheel processing material to the distributing cylinder 55 in a timely manner.

[0076] In this embodiment, the one-way drive assembly 57 includes a fixed rod 571, a push rod 572, a ratchet 573, and a ratchet 574. The fixed rod 571 is horizontally mounted on the sliding end of the second sliding assembly 42, the push rod 572 is vertically mounted on the fixed rod 571, the ratchet 573 is movably connected to the upper part of the push rod 572, and the ratchet 574 is mounted on the middle part of the rotating shaft 53. The ratchet 573 and the ratchet 574 mesh with each other.

[0077] The working process of the feeding mechanism 5 is as follows:

[0078] By controlling the sliding mechanism 2 and the telescopic mechanism 3, the rotating cylinder 43 moves to directly above the first lower mold 14 or the second lower mold 15, and the rotating cylinder 43 abuts against the annular protrusion. Since the rotating cylinder 43 is rotatably connected to the sliding end of the second sliding component 42, the telescopic mechanism 3 continues to extend. The rotating cylinder 43 pushes the second slider 422, the fixed rod 571, and the push rod 572 to move upward. The push rod 572 is equipped with a ratchet 573. The rotating shaft 53 is rotatably connected to the support member 412, and the housing 54 and the material distribution cylinder 55 are limited by the ball limit module 56. The ratchet 573 pushes the ratchet 574 to rotate upward, so that the first material distribution groove 551 or the second material distribution groove 552 rotates to the bottom of the housing 54, so that the first material distribution groove 551 or the second material distribution groove 552 matches the discharge hole. The grinding wheel processing material in the first material distribution groove 551 or the second material distribution groove 552 falls onto the inner bottom surface of the first lower mold 14 or the second lower mold 15 under the action of gravity.

[0079] This invention can simultaneously produce two different specifications of grinding wheels, which are referred to as the first grinding wheel and the second grinding wheel for easy distinction. The cross-sectional area of ​​the first grinding wheel is smaller than that of the second grinding wheel. The first grinding wheel is pressed and formed by the first lower die 14, and the second grinding wheel is pressed and formed by the second lower die 15. The space capacity of the first material distribution groove 551 and the second material distribution groove 552 corresponds to the first grinding wheel and the second grinding wheel, respectively. The outer side of the material distribution cylinder 55 abuts against the inner wall of the housing 54. This structure can accurately distribute materials according to the specifications of the first grinding wheel and the second grinding wheel in each material distribution process, and has a high degree of automation, requiring no other control devices.

[0080] In this embodiment, the multi-size grinding wheel processing device further includes a control system, which is installed on the worktable 11. The control system is electrically connected to the sliding mechanism 2, the telescopic mechanism 3, the laying mechanism 4, and the feeding mechanism 5. The sliding mechanism 2, the telescopic mechanism 3, the laying mechanism 4, the feeding mechanism 5, and the control system are all electrically connected to an external power supply system.

[0081] The first sliding component 13 can have a variety of different structures, as detailed in the first embodiment, the second embodiment, or others;

[0082] First embodiment:

[0083] The first sliding assembly 13 includes two first slide rails 131, four first sliders 132, and four torsion modules. The upper part of the worktable 11 is provided with a first through hole 111. The two first slide rails 131 are respectively horizontally installed on the front and rear inner walls of the first through hole 111. The four first sliders 132 are divided into two groups and are respectively installed on the front and rear sides of the first lower mold 14. One side of the first slider 132 is rotatably connected to the side of the first lower mold 14 through the torsion module, and the other side is movably connected to the corresponding first slide rail 131. The torsion module can be a coil spring module inside a measuring tape or other modules.

[0084] After the press presses two different sizes of grinding wheels into shape, the first lower die 14 and the second lower die 15 are separated from each other under the action of four torsion modules, which facilitates the connection of the grinding wheel to the next round of processing.

[0085] Second embodiment:

[0086] The first sliding assembly 13 includes two third slide rails, two third sliders, and a buffer module; the upper part of the worktable 11 has a third through hole, the two third slide rails are respectively obliquely installed on the front and rear inner walls of the third through hole, the inclination angle between the third slide rails and the transverse plane is between 5 and 30 degrees, the two third sliders are respectively slidably connected to the two third slide rails, the first lower mold 14 is fixedly installed between the two third sliders, the first lower mold 14 is parallel to the transverse plane, and the buffer module is installed on the left inner wall of the third through hole to buffer the first lower mold 14 to avoid the first lower mold 14 from being too fast and causing the first lower mold 14 to be destroyed.

[0087] After the press presses two different specifications of grinding wheels into shape, due to the oblique arrangement of the two third slide rails, the first lower die 14 and the second lower die 15 separate from each other under the action of the weight of the first lower die 14, which facilitates the connection of the grinding wheel to the next round of processing.

[0088] The working process of this invention is as follows:
