DETAILED DESCRIPTION

[0015] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0016] like Figure 1As shown, a straight-pull rough grinding machine includes a frame 1, a saw blade bracket arranged at the bottom of the frame 1, a saw blade clamping device arranged at the upper part of the frame 1, and a grinding device, wherein the grinding device includes a sliding frame 2 slidably arranged relative to the frame 1 along a plumb direction, a mounting frame 3 slidably arranged relative to the sliding frame 2 along a horizontal direction, a grinding head 4 rotatably arranged on the mounting frame 3, a first driving motor 5 driving the grinding head 4 to rotate, and a lifting driving mechanism 5 arranged between the sliding frame 2 and the frame 1 to drive the sliding frame 2 The saw blade clamping device comprises a lower clamping plate 6 fixedly arranged on the frame 1 and an upper clamping plate 7 slidingly arranged on the frame 1 along a horizontal direction. A linkage mechanism is arranged between the sliding frame 2 and the upper clamping plate 7, and the linkage mechanism comprises a driving connecting rod 8 with one end being rotatably connected to the upper clamping plate 7. A guide member 9 is slidably arranged on the sliding frame 2 along a vertical direction, and the other end of the driving connecting rod 8 is rotatably connected to the guide member 9.

[0017] Preferably, in this embodiment, the lifting drive mechanism includes a lifting screw rotatably arranged on the frame 1, the sliding frame 2 has a threaded hole matching the lifting screw, and the frame 1 is provided with a second drive motor 10 for driving the lifting screw to rotate.

[0018] A transmission mechanism is arranged between the second drive motor 10 and the lifting screw. The specific structure of the transmission mechanism is not the design focus of the present application. For example, gear transmission, worm gear transmission, pulley and belt transmission can all be used here. The preferred implementation in this embodiment preferably adopts sprocket transmission. Specifically, the transmission mechanism includes a first transmission sprocket 11 fixedly arranged on the motor shaft of the second drive motor 10, a second transmission sprocket 12 fixedly arranged on the lifting screw, and a transmission chain matching the first transmission sprocket 11 and the second transmission sprocket 12.

[0019] In the preferred implementation mode of the present embodiment, the horizontal driving mechanism is a driving cylinder, and a screw drive mode can also be adopted.

[0020] The preferred implementation method in this embodiment is that a guide portion 15 is fixedly provided on the sliding frame 2, and its length direction extends along the plumb direction. A guide groove extending along its length direction is provided on the guide portion 15. The guide member 9 is slidably located in the guide groove. In order to prevent the guide member 9 from detaching from the sliding frame 2, the guide groove is provided to not only play a guiding role but also a limiting role.

[0021] The preferred implementation manner in this embodiment is that the saw blade bracket includes a base 13 and a plurality of rollers 14 horizontally rotatably arranged on the base 13, and the plurality of rollers 14 are evenly distributed along the horizontal direction. By arranging a plurality of rotating rollers 14, the saw blade is in rolling contact with the rollers 14, which greatly reduces friction when the saw blade moves.

[0022] In order to ensure the straightness of the movement of the upper clamping plate 7, a guiding mechanism is arranged between the upper clamping plate 7 and the frame 1, and the guiding mechanism includes a guiding column 16 fixedly arranged on the frame 1, and a guiding sleeve 17 fixedly arranged on the upper clamping plate 7 and matched with the guiding column 16. The cooperation between the guiding column 16 and the guiding sleeve 17 enables the upper clamping plate 7 to move linearly under the action of the driving connecting rod 8.

[0023] Working process: first, place the annular saw blade on the frame 1, with the bottom of the saw blade on the saw blade bracket, and the upper part of the saw blade between the upper clamping plate 7 and the lower clamping plate 6, start the first drive motor 5 and the second drive motor 10, the first drive motor 5 drives the grinding head 4 to rotate, and the second drive motor 10 makes the sliding frame 2 slide downward so that the grinding head 4 conflicts with the upper surface of the saw blade, start the drive cylinder, the drive cylinder drives the mounting frame 3 to slide horizontally, and then drives the rotating grinding head 4 along the width direction of the saw blade Move, and at the same time, under the action of the driving connecting rod 8, the lower clamping plate 6 and the upper clamping plate 7 clamp the saw blade, and one of the contact surfaces of the upper clamping plate 7 or the lower clamping plate 6 is an inclined surface, and then when the upper clamping plate 7 slides, the distance between the two gradually becomes smaller to achieve the clamping of the saw blade. After the grinding is completed, the driving cylinder is reset to make the upper clamping plate 7 move away from the lower clamping plate 6, and the second driving motor 10 is reversed to make the grinding head 4 separate from the surface of the saw blade, and the saw blade is manually moved to grind the next section of the saw blade. Not only is the degree of automation high but also the labor intensity is reduced.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
