Detailed Implementation

[0024] The present invention will be further described below with reference to specific embodiments.

[0025] like Figures 1-3 As shown, this utility model discloses a double-sided grinding machine, including a bed 1 and a saw blade feeding mechanism 4. The bed is also provided with a central saw blade positioning mechanism 3 with clamping positions on both sides. The central saw blade positioning mechanism can be flipped and changed in the vertical direction to change the position of the clamping position. Grinding wheel mechanisms 2 are respectively provided on both sides of the central saw blade positioning mechanism.

[0026] In one specific embodiment, the grinding wheel mechanism is mounted entirely on an arc-shaped guide rail 13. Driven by a motor, the grinding wheel mechanism can move along the arc-shaped guide rail to adapt to the processing requirements of the saw blade to be processed. Furthermore, grinding wheel mechanisms are arranged on both sides of the central saw blade positioning mechanism, enabling simultaneous processing of two saw blades. By flipping and adjusting the direction of the saw blades, the other side of the saw blade can be processed, significantly improving processing efficiency.

[0027] In one embodiment, the central saw blade positioning mechanism is mounted on a horizontal traversing mechanism 12. The central saw blade positioning mechanism includes a base 32, on which a saw blade positioning platform 31 is connected via a rotating shaft. Longitudinal positioning components 11 are respectively installed on both sides of the saw blade positioning platform. The central saw blade positioning mechanism is positioned on the horizontal traversing mechanism 12, and its lateral movement, driven by the movement of the horizontal traversing mechanism 12, completes the position switching between the loading station and the grinding station. The longitudinal positioning components mainly control the lifting and lowering of the pressure plate via a cylinder, pressing the loaded saw blade downwards. A platform base is provided in a localized area of ​​the machine bed, and a robotic arm can be installed on the platform base to grip the processed saw blade.

[0028] like Figure 4The diagram shows an automatic saw blade feeding mechanism configured for a double-sided grinding machine according to this utility model. It includes a frame 18, a feeding platform 16 within the frame 18, a discharge limiting structure at the inner end of the feeding platform 16, and a corresponding discharge clamping structure 15 located at the inner end of the feeding platform 16. The discharge clamping structure is adjustable in height. A discharge transmission structure is located at the upper end of the frame, receiving the saw blades to be processed from the discharge clamping structure and transmitting them to the grinding station. The saw blades are placed onto the feeding platform manually or by a robotic arm and arranged sequentially. The discharge limiting structure controls the sequential discharge of the saw blades, blocking and limiting the discharge of each blade. The blades are then alternately transported to the grinding station for subsequent processing via the discharge clamping structure and the discharge transmission structure.

[0029] In one embodiment, the feeding platform is arranged at an angle with an adjustable tilt angle. The discharge limiting structure includes a baffle located at the inner end of the feeding platform, the extension position of which is controlled by a first cylinder 6. A second cylinder 7 is connected to the bottom of the feeding platform, and the second cylinder extends and retracts to adjust the tilt angle of the feeding platform. At a certain tilt angle, the saw blade naturally rests against the baffle of the discharge limiting structure. After the baffle is retracted under the control of the first cylinder, the saw blade at the outermost end is released from restriction and is clamped by the discharge clamping structure. A third cylinder 8 is connected to the lower part of the discharge clamping structure, and the third cylinder 8 can adjust the lifting height of the entire discharge clamping structure to match the outlet section of the discharge platform.

[0030] In one embodiment, the discharge conveying structure includes a transverse guide rail disposed above the frame, a transverse sliding plate 10 disposed on the transverse guide rail, and a lifting mechanism 17 mounted on the sliding 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 discharge clamping structure. Therefore, by adjusting the lifting of the lifting mechanism 17 and controlling the action of the clamping block by the clamping cylinder, the saw blade receiving the discharge clamping structure can be transferred. Finally, the transverse sliding plate is moved outward by the motor to perform subsequent saw blade transmission.

[0031] like Figure 5 As shown, a saw blade clamping and limiting structure 5 is provided at the outer end of the frame. The clamping and limiting structure 5 is mainly for precise limiting of the saw blade before it is transmitted to the central saw blade positioning mechanism 3, so as to ensure accurate subsequent processing.

[0032] Specifically, the saw blade clamping and limiting structure 5 includes front and rear positioning components and side positioning components. It mainly achieves precise positioning through front-rear and lateral positioning.

[0033] In one embodiment, the saw blade clamping and limiting structure includes a horizontal limiting platform 24. A limiting block 20, adjustable in position for forward and backward movement, is provided on the horizontal limiting platform. The two sides of the horizontal limiting platform are connected to a fixed bracket 19 via hinges, and a fourth cylinder 21 is connected to the lower end of the horizontal limiting platform. The fourth cylinder's operation adjusts the tilt angle of the horizontal limiting platform to achieve forward and backward position limiting. The top surface of the limiting block has a through groove, and the horizontal limiting platform also has multiple limiting holes. The ejection position of the limiting block can be adjusted in advance according to the positioning requirements of the saw blade.

[0034] In one embodiment, the side positioning component includes a side positioning cylinder 23 disposed in front of the horizontal limiting platform, the side positioning cylinder controlling the left and right movement of the side positioning push block 22. Lateral positioning is mainly achieved by the side positioning cylinder 23 pushing the side positioning push block 22 out of its position.

[0035] The working process of this utility model is as follows: The saw blades are placed onto the feeding platform by a person or a robot and arranged in sequence. The discharge limiting structure controls the saw blades to be discharged one by one, and the discharge limiting structure blocks and limits the discharge of each blade. The blades are then alternately transported to the grinding station via the discharge clamping structure and the discharge conveying structure.

[0036] At a certain tilt angle, the saw blade naturally rests against the baffle of the discharge limiting structure. After the baffle is retracted under the control of the first cylinder, the saw blade at the outermost end is released from restriction and is clamped by the discharge clamping structure. The lower part of the discharge clamping structure is connected to the third cylinder 8, which can adjust the lifting height of the entire discharge clamping structure to match the outlet section of the discharge platform.

[0037] The orientation of the automatic clamping structure is opposite to that of the discharge clamping structure. Therefore, by adjusting the lifting mechanism 17 and controlling the clamping block movement by the clamping cylinder, the saw blade on the receiving discharge clamping structure can be moved outward to the saw blade clamping limit structure 5 by the motor-controlled transverse sliding plate.

[0038] The central saw blade positioning mechanism 3 moves to the position of the saw blade clamping and limiting structure 5 via the horizontal traversing mechanism 12, and the saw blade clamping and limiting structure 5 transfers the saw blade to the central saw blade positioning mechanism 3 for clamping. The central saw blade positioning mechanism 3 returns to the grinding station for double-sided machining.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
