Description

Technical Field

[0001] The invention relates to the technical field of grinding wheel production, in particular to a rotary grinding wheel automatic forming machine with high stability. Background Art

[0002] Grinding wheel forming machine is a special equipment used to make grinding wheels. Grinding wheel pressing technology is a low-cost and high-efficiency grinding wheel forming process method, which has been more and more widely used in the abrasive tool processing industry.

[0003] When people produce grinding wheels, they generally use grinding wheel automatic forming machines to produce grinding wheels. When an existing fully automatic rotary multi-station grinding wheel forming machine produces grinding wheels, in order to ensure that the forming machine can achieve automatic rotation, the column of the press in the pressing mechanism of the grinding wheel forming machine is allowed to pass through the center of the mold mounting frame. This ensures that the wheel on the mold mounting frame can rotate on the mold mounting frame while the pressing station on the wheel can rotate and pass under the pressing point of the press, so as to facilitate the continuous pressing of the grinding wheel.

[0004] The above-mentioned existing grinding wheel forming technology has the following technical defects: in order to ensure that the pressing station on the wheel disc can continuously pass under the pressing point of the press, a column of the press is coaxially arranged with the center axis of the wheel disc, which affects the distance between the column passing through the wheel disc and the pressing point of the press, resulting in the distance between the pressing point of the press and the center axis of the wheel disc cannot be changed. The press requires a lot of pressure when pressing and forming the grinding wheel. The farther the distance between the pressing point of the press and the center of the wheel disc, that is, the longer the force arm during the pressing process, the more unstable the press is when pressing the grinding wheel, the weaker the rigidity is, and it is difficult to produce better quality grinding wheels. Summary of the invention

[0005] The purpose of the present invention is to provide a highly stable rotary grinding wheel automatic forming machine, which has the characteristic that the length of the force arm of the grinding wheel is less than the length between the pressing point of the press and the center axis of the wheel disc when pressing the grinding wheel. This can make the invention more stable during operation and can produce better quality grinding wheels.

[0006] The above-mentioned object of the present invention is achieved through the following technical solutions:

[0007] A highly stable rotary grinding wheel automatic forming machine comprises a base and a mounting plate mounted on the base, a swivel disk is mounted on the mounting plate via a supporting mechanism, the supporting mechanism comprises a supporting seat, a supporting column and an arc plate supporting assembly, the supporting column is mounted on the mounting plate, the supporting seat is mounted on the supporting column, the arc plate supporting assembly is arranged at the bottom of the swivel disk, the swivel disk is rotatably connected to the supporting seat via a driving assembly, the center of the supporting seat corresponds to the center of the swivel disk, a press is mounted on the base, a through hole is provided on the supporting seat for the column of the press to pass through, a sliding block is provided on the press, the sliding block is located above the swivel disk, a pressing piece for pressing the grinding wheel is provided on the sliding block, and a horizontal distance between the pressing piece and the column of the press passing through the through hole is smaller than a horizontal distance between the pressing piece and the central axis of the swivel disk.

[0008] By adopting the above technical solution, the horizontal distance between the pressed part and the through hole on the support seat is smaller than the horizontal distance from the pressed part to the central axis of the rotating ring disk, which can greatly reduce the length of the force arm during the pressing process, enhance the rigidity of the press, and produce better quality grinding wheels.

[0009] The present invention is further configured as follows: the driving assembly includes a reversing reduction box, a driving motor, a driving gear, a cross roller bearing and an outer ring gear, the reversing reduction box and the driving motor are both mounted on a mounting plate, a motor wheel is mounted on the output shaft of the driving motor, a speed change wheel is mounted on the input shaft of the reversing reduction box, the motor wheel and the speed change wheel are both wound with the same transmission belt, the driving gear is mounted on the output shaft of the reversing reduction box, the cross roller bearing is arranged between the support seat and the rotating ring disk, the bottom surface of the inner ring of the cross roller bearing is fixedly connected to a side of the support seat away from the support column, the top surface of the inner ring of the cross roller bearing is fixedly connected to a connecting side ring, the connecting side ring is fixedly connected to the bottom surface of the rotating ring disk, the outer ring gear is arranged on the outer ring side of the cross roller bearing, and the outer ring gear and the driving gear are meshed with each other.

[0010] By adopting the above technical scheme, the driving motor drives the reversing reduction box to rotate through the transmission belt. The reversing reduction box changes the driving direction while controlling the speed, so that the vertically rotating motor output shaft can drive the reversing reduction box through the belt, so that the output of the reversing reduction box rotates horizontally, and the output shaft of the horizontally rotating reversing reduction box drives the driving gear to rotate, the driving gear drives the outer ring gear to rotate, the outer ring gear drives the outer ring of the cross roller bearing to rotate, and then drives the swivel disk to rotate, realizing the rotation operation of the swivel disk. The setting of the cross roller bearing can bear great axial force and radial force, which greatly increases the rigidity and stability of the swivel disk during rotation.

[0011] The present invention is further configured as follows: the arc plate support assembly includes a plurality of arc ring plates and a plurality of bearing trays, the arc ring plates are fixed on the mounting plate by means of "Ⅱ"-shaped fixing parts, the bearing trays are fixed between two adjacent arc ring plates, a plurality of grinding wheel processing stations are arranged on the rotating ring plate, a material tray is arranged in the grinding wheel processing station, the grinding wheel processing station corresponds to the bearing trays, and the bearing trays and the material trays are in conflict with each other.

[0012] By adopting the above technical solution, the arc-shaped ring plate and the support plate together form a supporting structure under the rotating ring plate. When the material tray stops under the pressing part of the press, the support plate can provide support for the material tray when the pressure mesh plate and the pressure plate are pressed against the material tray, thereby preventing the material tray from being damaged due to excessive pressure.

[0013] The present invention is further configured as follows: the pressing part includes a fixed plate, an electric heating plate and a pressure plate, the fixed plate is installed at the bottom of the sliding block, the electric heating plate is installed on a side of the fixed plate away from the sliding block, and the pressure plate is installed on a side of the electric heating plate away from the fixed plate.

[0014] By adopting the above technical solution, the pressure plate is responsible for pressing the abrasive used to make the grinding wheel, the electric heating plate is convenient for heating the pressure plate to help the hot pressing of the grinding wheel, and the fixed plate is directly installed on the sliding block to provide support for the electric heating plate and the pressure plate.

[0015] The present invention is further configured as follows: the grinding wheel processing stations are evenly distributed on the ring plates of the rotating ring disk and are all located below the sliding block; when the rotating ring disk rotates, the grinding wheel processing stations all pass below the pressure plate.

[0016] By adopting the above technical solution, the grinding wheel processing station on the rotating wheel disc can only realize the continuous pressing of the grinding wheel disc by passing under the pressure plate, thereby accelerating the production of the grinding wheel disc and realizing the rotary production of the grinding wheel disc.

[0017] In summary, the beneficial technical effects of the present invention are:

[0018] 1. The column on the press passes through the perforation on the support seat, and the horizontal distance between the press column passing through the perforation and the pressed part on the press is smaller than the distance between the pressed part and the central axis of the rotating ring disc. This can greatly reduce the length of the force arm of the grinding wheel during the pressing process, enhance the rigidity of the press, make the pressing process of the press more stable when pressing the grinding wheel, and produce better quality grinding wheels;

[0019] 2. The setting of the cross roller bearing can not only fix the position of the swivel disc on the mounting plate, but also realize the rotation of the swivel disc. Moreover, the cross roller bearing can bear great axial force and radial force, which greatly increases the rigidity and operation stability of the swivel disc during rotation.

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0028] Reference Figure 1 A high-stability rotary grinding wheel automatic forming machine includes a base 1 and a mounting plate 2 mounted on the base 1. No less than two human-shaped support plates 21 are mounted on the side wall of the mounting plate 2. The human-shaped support plates 21 are arranged on the mounting plate 2. A control panel 22 is mounted on one end of the human-shaped support plate 21 away from the mounting plate 2. The control panel 22 is mounted with a forming machine power box 221 for controlling the power supply of the invention and a forming machine control box for controlling the operation of the invention. Other production devices for producing grinding wheels are also mounted on the mounting plate (not shown in the figure).

[0029] Reference Figure 2 and Figure 3A rotating disk 4 is installed between the mounting plate 2 and the control panel 22 through a supporting mechanism 3, and the supporting mechanism 3 includes a supporting seat 31, a supporting column 32 and an arc-shaped plate supporting assembly 33. The supporting column 32 is installed on the mounting plate 2, the supporting seat 31 is installed on the supporting column 32, and the arc-shaped plate supporting assembly 33 is arranged at the bottom of the rotating disk 4.

[0030] Reference, 3 and Figure 4 The support seat 31 is circular, and the rotating ring disk 4 is rotatably connected to the support seat 31 through the driving assembly 5, and the center of the support seat 31 corresponds to the center of the rotating ring disk 4. The driving assembly 5 includes a reversing reduction box 51, a driving motor 52, a driving gear 53, a cross roller bearing 54 and an outer ring gear 55. The reversing reduction box 51 and the driving motor 52 are both mounted on the mounting plate 2, and a motor wheel (not shown in the figure) is mounted on the output shaft of the driving motor 52, and a speed-changing wheel 511 is mounted on the input shaft of the reversing reduction box 51, and the driving gear 53 is mounted on the output shaft of the reversing reduction box 51, and the motor wheel and the speed-changing wheel 511 are both wound with the same transmission belt 512. The cross roller bearing 54 is arranged between the support seat 31 and the rotating ring disk 4. The inner ring bottom surface of the cross roller bearing 54 is fixedly connected to the side of the support seat 31 away from the support column 32. The inner ring top surface of the cross roller bearing 54 is fixedly connected with a connecting side ring 541. The connecting side ring 541 is fixedly connected to the bottom surface of the rotating ring disk 4. The outer ring gear 55 is arranged on the outer ring side surface of the cross roller bearing 54. The outer ring gear 55 is meshed with the driving gear 53. The cross roller bearing 54 can not only fix the position of the rotating ring disk 4 on the mounting plate 2, but also realize the rotation of the rotating ring disk 4. Moreover, the cross roller bearing 54 can bear great axial force and radial force, which greatly increases the rigidity and operation stability of the rotating ring disk 4 during the rotation process, making the processing of the grinding wheel more stable.

[0031] Reference Figure 1 and Figure 4 , a press 6 is mounted on the base 1, a through hole 311 is provided on the support seat 31 for the column of the press 6 to pass through, a sliding block 61 is slidably connected to the column on the press 6, the sliding block 61 is driven by the pressure mechanism of the press 6, the sliding block 61 is located above the rotating ring disk 4, a pressing piece 7 for pressing the grinding wheel is provided on the sliding block 61, and the horizontal distance between the pressing piece 7 and the column of the press 6 passing through the through hole 311 is smaller than the horizontal distance between the pressing piece 7 and the central axis of the rotating ring disk 4. The smaller the horizontal distance between the column of the press 6 and the pressing piece 7 on the press 6, the shorter the length of the force arm of the grinding wheel during the pressing process, the stronger the rigidity of the press 6, and the more stable the press 6 will be during the pressing process when pressing the grinding wheel, and better quality grinding wheels can be produced.

[0032] Reference Figure 5 and Figure 6The pressing member 7 includes a fixed plate 71, an electric heating plate 72 and a pressure plate 73. The fixed plate 71 is installed at the bottom of the sliding block 61, the electric heating plate 72 is installed on the side of the fixed plate 71 away from the sliding block 61, and the pressure plate 73 is installed on the side of the electric heating plate 72 away from the fixed plate 71.

[0033] Reference Figure 3 The arc plate support assembly 33 includes a plurality of arc ring plates 331 and a plurality of bearing trays 332. The arc ring plates 331 are fixed on the mounting plate 2 through a "Ⅱ"-shaped fixing member 34, and the bearing tray 332 is fixed between two adjacent arc ring plates 331. A plurality of grinding wheel processing stations 41 are arranged on the rotating ring plate 4, and the grinding wheel processing stations 41 are evenly distributed on the annular surface of the rotating ring plate 4 along the circumferential direction of the rotating ring plate 4. The rotating ring plate 4 is driven by the driving assembly 5 to rotate under the sliding block 61, and when the rotating ring plate 4 rotates, a plurality of grinding wheel processing stations 41 pass under the pressure plate 73 in sequence. A material tray 42 is placed in the grinding wheel processing station 41, and the grinding wheel processing station 41 corresponds to the bearing tray 332, and the bottom surface of the material tray 42 is in conflict with the bearing tray 332.

[0034] The implementation principle of this embodiment is as follows: when people use this invention to produce grinding wheel discs, they first put the abrasives for manufacturing grinding wheel discs into the empty material tray 42, and then start the driving motor 52. The driving motor 52 drives the rotating ring disc 4 to rotate through the cross roller bearing 54. The rotating ring disc 4 rotates above the mounting plate 2 driven by the cross roller bearing 54. After processing the abrasives in the material tray 42, the other grinding wheel disc processing devices installed on the base 1 will pass under the sliding block 61 in turn. When the material tray 42 moves to the bottom of the pressing part 7, the press 6 drives the sliding block 61 to press against the material tray 42. The pressing plate 73 heat-presses the abrasives in the material tray 42 under the heating of the electric heating plate 72. The supporting plate 332 provides better support for the material tray 42 under the support of the "Ⅱ"-shaped fixing part and the arc-shaped ring plate 331, preventing the material tray 42 from collapsing due to excessive pressure.

[0035] In the process of producing grinding wheels according to the invention, very little manpower is required, which greatly saves labor costs. The distance between the column of the press 6 passing through the support seat 31 and the pressing point of the press 6 is smaller than the distance between the pressing point and the central axis of the rotating ring disk 4, which can make the press 6 more rigid, make the press 6 more stable when pressing the grinding wheel, and produce higher-quality grinding wheels. The use of the cross roller bearing 54 greatly increases the rigidity and operation stability of the rotating ring disk 4 during the rotation process, making the processing of the grinding wheel more stable.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
