Specific embodiments

[0021] The present invention will be further described below in conjunction with specific embodiments.

[0022] As Figures 1-3 shown, the present invention discloses a double-sided grinding machine, including a bed body 1 and a saw blade loading mechanism 4. A center saw blade positioning mechanism 3 with clamping stations on both sides is also provided on the bed body. The center saw blade positioning mechanism can flip and switch the positions of the clamping stations in the vertical direction. Grinding wheel mechanisms 2 are respectively arranged on both sides of the center saw blade positioning mechanism.

[0023] In a specific embodiment, the grinding wheel mechanism is integrally installed on an arc-shaped guide rail 13. The grinding wheel mechanism can move along the arc guide rail driven by a motor to adapt to the processing requirements of the saw blade to be processed. And the grinding wheel mechanisms are correspondingly arranged on both sides of the center saw blade positioning mechanism, enabling simultaneous processing of two saw blades. After flipping and adjusting the saw blade orientation, the other side of the saw blade can be processed, significantly improving the processing efficiency.

[0024] In an embodiment, the center saw blade positioning mechanism is arranged on a horizontal transverse movement mechanism 12. The center saw blade positioning mechanism includes a base 32. A saw blade positioning platform 31 is connected to the base 32 through a rotating shaft. Longitudinal positioning components 11 are respectively arranged on both sides of the saw blade positioning platform. The center saw blade positioning mechanism is positioned on the horizontal transverse movement mechanism 12, and its horizontal movement is driven by the action of the horizontal transverse movement mechanism 12 to complete the position switching between the loading station and the grinding processing station. The longitudinal positioning components mainly control the lifting of the pressing plate through a cylinder, and press the saw blade after loading downward through the pressing plate. A platform base is arranged in a local area of the bed body, and a manipulator can be arranged on the platform base to pick up the processed saw blade.

[0025] As Figure 4Shown is an automatic saw blade loading mechanism configured for a double-sided grinding machine of the present invention, which includes a frame 18. An upper loading platform 16 is arranged inside the frame 18. An end-of-discharge limiting structure is arranged at the inner end of the upper loading platform 16. An end-of-discharge clamping structure 15 is correspondingly arranged at the inner end of the upper loading platform 16. The end-of-discharge clamping structure can be adjusted up and down. An end-of-discharge transmission structure is arranged at the upper end of the frame. The end-of-discharge transmission structure receives the saw blade to be processed on the end-of-discharge clamping structure and transports it to the grinding processing station. The saw blades are placed on the upper loading platform manually or by a manipulator and arranged in sequence. The end-of-discharge limiting structure controls the saw blades to be discharged in sequence. After one is discharged, it blocks and limits. It is alternately transmitted to the grinding processing station through the end-of-discharge clamping structure and the end-of-discharge transmission structure for subsequent processing.

[0026] In one embodiment, the upper loading platform is obliquely arranged with an adjustable inclination angle. The end-of-discharge limiting structure includes a baffle arranged at the inner end of the upper loading platform. The extending position of the baffle is controlled by a first cylinder 6. The bottom of the upper loading platform is connected to a second cylinder 7. The second cylinder expands and contracts to adjust the inclination angle of the upper loading platform. At a certain inclination angle, the saw blade naturally abuts against the baffle of the end-of-discharge limiting structure. After the baffle is retracted by the first cylinder, the saw blade at the outermost end is released from the restriction, and the end-of-discharge clamping structure is docked for clamping. The lower part of the end-of-discharge clamping structure is connected to a third cylinder 8. The third cylinder 8 can adjust the lifting height of the entire end-of-discharge clamping structure to match the outlet section of the upper loading platform.

[0027] In one embodiment, the end-of-discharge transmission structure includes a transverse movement guide rail arranged above the frame. A transverse movement slide plate 10 is arranged on the transverse movement guide rail. A lifting mechanism 17 is installed on the slide plate. The lifting mechanism 17 is connected to an automatic clamping structure 9. The orientation of the automatic clamping structure is opposite to that of the end-of-discharge clamping structure. Therefore, through the lifting adjustment of the lifting mechanism 17 and then controlling the clamping block to act through the clamping cylinder, the saw blade received on the end-of-discharge clamping structure can be clamped. Finally, the transverse movement slide plate is controlled by a motor to move outward for the subsequent transmission work of the saw blade.

[0028] As Figure 5 shown, a saw blade clamping and limiting structure 5 is arranged at the outer end of the frame. The clamping and limiting structure 5 is mainly used to accurately limit the saw blade before it is transmitted to the central saw blade positioning mechanism 3 to ensure subsequent accurate processing.

[0029] Specifically, the saw blade clamping and limiting structure 5 includes a front and rear positioning component and a side positioning component. It mainly performs accurate positioning in the front and rear and lateral directions.

[0030] In one embodiment, the saw blade clamping and limiting structure includes a horizontal limiting platform 24, on which a limiting block 20 capable of adjusting the in-and-out position back and forth is provided. The two sides of the horizontal limiting platform are connected to a fixed bracket 19 through hinges, and the lower end of the horizontal limiting platform is connected to a fourth cylinder 21. By the action of the fourth cylinder, the inclination angle of the horizontal limiting platform is adjusted to achieve the front-back position limiting. A through groove is formed on the top surface of the limiting block, and there are also a plurality of limiting holes on the horizontal limiting platform. According to the positioning requirements of the processed saw blade, the ejecting position of the limiting block can be adjusted in advance.

[0031] In one embodiment, the side positioning component includes a side positioning cylinder 23 arranged in front of the horizontal limiting platform, and the side positioning cylinder controls the left-right movement of a side positioning push block 22. The lateral positioning mainly depends on the position where the side positioning cylinder 23 pushes out the side positioning push block 22 for side positioning.

[0032] The working process of the present invention is as follows: The saw blades are placed on the feeding platform manually or by a manipulator and arranged in sequence, and are controlled by the discharging limiting structure to be discharged in sequence. After one is discharged, it is blocked and limited. It is alternately transmitted to the grinding processing station through the discharging clamping structure and the discharging transmission structure.

[0033] At a certain inclination angle, the saw blade naturally abuts against the baffle of the discharging limiting structure. After the baffle is retracted by the first cylinder, the saw blade at the outermost end is released from the restriction, and is clamped by the docking of the discharging clamping structure. The lower part of the discharging clamping structure is connected to a third cylinder 8, and the third cylinder 8 can adjust the lifting height of the entire discharging clamping structure to match the outlet section of the discharging platform.

[0034] The orientation of the automatic clamping structure is opposite to that of the discharging clamping structure. Therefore, through the lifting adjustment of the lifting mechanism 17 and then controlling the clamping block to act through the clamping cylinder, the saw blade on the discharging clamping structure can be received, and finally the motor controls the transverse sliding plate to move outwards to the saw blade clamping and limiting structure 5.

[0035] The central saw blade positioning mechanism 3 moves to the position of the saw blade clamping and limiting structure 5 through the horizontal transverse movement mechanism 12, and the saw blade is transmitted to the central saw blade positioning mechanism 3 by the saw blade clamping and limiting structure 5 for clamping. The central saw blade positioning mechanism 3 returns to the grinding station for double-sided processing.
