DETAILED DESCRIPTION

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

[0022] like Figure 1-Figure 2A straight saw and curved saw processing grinder shown in the figure includes a frame 1 and a grinding wheel mechanism 5. An automatic feeding mechanism and a blade clamping and fastening mechanism are arranged on the frame. The blade clamping and fastening mechanism includes a positioning platform 6. The positioning platform is installed on the horizontal transverse movement mechanism. A grinding wheel mechanism guide device is arranged on one side of the positioning platform. The guide device includes a horizontal rotating platform 2. A front and rear feed seat 4 is arranged on the horizontal rotating platform. A grinding wheel mechanism 5 which can be steered and adjusted in a vertical plane is arranged at the front end of the front and rear feed seat.

[0023] The automatic feeding mechanism transfers the saw blade to the positioning platform for fastening, and then the grinding wheel mechanism processes the saw blade with positive and negative angles and chamfers. The grinding wheel mechanism also includes a water spray device for real-time cooling during the processing process.

[0024] In one embodiment, an end positioning induction block 8 is provided at one end of the positioning platform, and a side positioning block 7 is provided on the outer side of the positioning platform. When the automatic feeding mechanism transfers the saw blade to the positioning platform, dual positioning is performed through the end positioning induction block and the side positioning block to ensure the accuracy of the positioning position and the precision of subsequent processing.

[0025] Specifically, the end positioning sensing block 8 is directly fixed to one end of the positioning platform, and the side positioning block is positioned on the frame and is located on the side of the positioning platform.

[0026] In one embodiment, a lifting and moving top pressure block 10 is also provided on the positioning platform, and an air blowing mechanism is also provided facing the positioning platform. After the end positioning and the side positioning are completed, the sensor transmits the signal to the control system, and the top pressure block is connected to the top pressure rod 9 of the lifting cylinder, and the top pressure block presses down against the saw blade to complete the positioning. The air blowing mechanism is provided to clean the positioning platform before processing to ensure the processing quality.

[0027] Specifically, one end of the horizontal rotating platform 2 is connected to the horizontal rotating driving mechanism 18 through a fastener, and the other end of the horizontal rotating platform is provided with a front and rear feed seat 4. The horizontal rotating driving mechanism 18 can be a rotary motor, which rotates with one end of the rotary motor as the axis to adjust the horizontal steering position of the feed seat to adjust the processing angle of the saw blade.

[0028] Specifically, the horizontal rotating platform 2 is provided with front and rear guide rails, the front and rear feed seats 4 are installed on the front and rear guide rails, the front end of the front and rear feed seats is provided with a longitudinal rotation drive mechanism 3, and the longitudinal rotation drive mechanism is connected to the grinding wheel mechanism 5. The front and rear feed seats can move forward and backward on the front and rear guide rails, and the front and rear positions can be adjusted to achieve the processing of the overall curvature of the saw blade, that is, to process the curved saw, and can also perform subsequent chamfering. The longitudinal rotation drive mechanism includes a longitudinally arranged rotary motor, and the processing of the positive and negative angles of the saw blade is achieved by adjusting the longitudinal rotation angle.

[0029] In one embodiment, the automatic feeding mechanism includes a multi-directionally adjustable mechanical arm 16, and a plurality of suction cups 15 are arranged at the lower end of the mechanical arm. The magnetic suction cups suck the saw blade to complete the transfer of the workpiece. The mechanical arm can move in the left and right and front and back directions, so as to facilitate flexible suction and placement of the saw blade.

[0030] Specifically, there are two suction cups, which are installed in the long slot of an extension plate 14 through fasteners. The spacing between the two suction cups can be adjusted as needed to better absorb according to the specifications of the saw blade.

[0031] In one embodiment, a material bin is further included, and the material bin includes a bracket 13 symmetrically arranged on both sides, and a plurality of partitions are evenly formed in the height direction of the bracket, and a saw blade slot 12 is formed between the upper and lower adjacent partitions. A large number of saw blades are pre-stacked in the material bin, and are sucked out in sequence by the automatic feeding mechanism for processing according to processing requirements.

[0032] In order to uniformly store and collect the processed saw blades, a finished product bin 11 is arranged outside the bin. As shown in the figure, the finished product bin can be an outer frame with an open top.

[0033] In one embodiment, the material bin, the finished product bin and the positioning platform are all arranged on a horizontal transverse platform 19, and the mechanical arm is mounted on a multi-directionally adjustable suspension mounting frame 17. The positioning platform is positioned on the horizontal transverse platform to realize the mobile processing of each blade on the saw blade, and the combined processing is performed in conjunction with the grinding wheel mechanism 5. The suspension mounting frame 17 is arranged above the horizontal transverse platform, so that its movement process is free from interference.

[0034] The working process of the utility model is as follows: the saw blades are uniformly stacked in the material bin, and the mechanical arm of the automatic feeding mechanism drives the suction cup to take out a saw blade and place it on the positioning platform. Before placement, the positioning platform is cleaned by the blowing mechanism before processing to ensure the processing quality. After the saw blade placed on the platform is reliably positioned by the end positioning sensor block 8 and the side positioning block, the information is transmitted to the control system, and the control system controls the lifting cylinder to press the top pressure block down to support the saw blade to complete the positioning.

[0035] At this time, the horizontal transverse platform moves away from the side positioning block, so that the saw blade is exposed in front of the grinding wheel mechanism. According to the specifications of the saw blade to be processed, the control system implements the processing process on the saw blade according to the set specification parameters. Specifically, during the straight saw processing, the longitudinal rotation drive mechanism adjusts the grinding wheel to a suitable angle, and the horizontal transverse platform drives the positioning platform to pause or move horizontally according to the set time. The feed seat pushes the grinding wheel to move back and forth for grinding or exiting the processing station, thereby realizing the blade processing of the saw blade in one direction; after the processing in one direction is completed, the longitudinal rotation drive mechanism adjusts the grinding wheel to the corresponding angle in the opposite direction, thereby realizing the reverse angle processing of the blade on the saw blade. After the positive and negative angle processing is completed, the longitudinal rotation angle of the grinding wheel is adjusted to cooperate with the movement of the feed seat for chamfering. During the processing of the curved saw, it is also necessary to adjust the rotation position of the horizontal rotation drive mechanism 18, and the feed depth of the feed seat is also different from the set data for the straight saw processing.

[0036] It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
