[0002] In the field of machining, saw blades are important cutting tools. Drilling mounting holes at the center of the saw blade is one of the key processes in the machining of saw blades.

[0003] Traditional saw blade manufacturing and processing uses opening devices that are mostly single-station processing, which cannot achieve continuous processing of saw blade mounting holes. After each processing is completed, the saw blade needs to be removed manually, the debris needs to be cleaned, and a new saw blade needs to be placed for processing. In addition, the removal of the saw blade requires manual operation to release the saw blade clamp and then take out the saw blade. The operation is cumbersome, the whole process is time-consuming, and the production efficiency is low. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an opening device for saw blade production and processing, solving the problem of low processing efficiency of saw blade mounting holes in traditional opening devices for saw blade production and processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an opening device for saw blade production and processing, comprising a processing table and a turntable. Saw blade positioning frames are fixedly connected to both sides of the top of the processing table via connectors. Placement plates are provided on both sides of the bottom of the inner cavity of the saw blade positioning frame. Blocking strips are fixedly connected to the front and rear sides of the top of the placement plates. Vertical rods are slidably connected to both sides of the top of the processing table via through holes. A sliding sleeve is fixedly connected to the top of the vertical rod. A horizontal rod is slidably connected inside the sliding sleeve. One end of the horizontal rod passes through the saw blade positioning frame and extends into the inner cavity of the saw blade positioning frame. A clamping plate is fixedly connected to one end of the rod extending into the inner cavity of the saw blade positioning frame. Vertical grooves that cooperate with the clamping plate are opened on both sides of the inner cavity of the saw blade positioning frame. An abutment block is fixedly connected to the other end of the crossbar. A first spring is sleeved on the outer periphery of the crossbar between the abutment block and the sliding sleeve. A fixing plate is fixedly connected to the bottom end of the vertical rod. A second spring is fixedly connected between the top of the fixing plate and the bottom of the turntable. A column is fixedly connected to one side of the top of the processing table. A stabilizing plate is fixedly connected to the top of one side of the column. Arc-shaped plates that cooperate with the abutment block are fixedly connected to both sides of the bottom of the stabilizing plate through connecting rods.

[0006] Preferably, a cylinder is installed at the bottom of the stabilizing plate, a telescopic rod is fixedly connected to the telescopic end of the cylinder, a drilling machine is installed at the bottom end of the telescopic rod, L-shaped rods are fixedly connected to both sides of the telescopic rod, and a clamping plate that cooperates with the clamping plate is fixedly connected to the bottom end of the L-shaped rod.

[0010] This utility model provides an opening device for saw blade production and processing. It has the following beneficial effects:

[0011] This invention achieves initial positioning and stable clamping of the saw blade through the cooperation of a saw blade positioning frame, a placement plate, a clamping plate, a contact block, a crossbar, an arc-shaped plate, and a clamping plate. When the turntable rotates, the contact block contacts the arc-shaped plate, and under the pressure of the arc-shaped plate, the crossbar drives the clamping plate to move into the saw blade positioning frame. Then, the clamping plate moves downward to contact the clamping plate and clamp the saw blade, preventing the saw blade from shifting or shaking during drilling. Through the cooperation between the turntable and the two saw blade positioning frame structures, continuous processing of the saw blade mounting holes is achieved. After drilling one saw blade, without much manual intervention, the drive motor can drive the turntable to rotate and rotate the next saw blade to be processed to the processing station. At the same time, after the saw blade is processed, it rotates to the auxiliary station, and the clamping plate is reset by the elastic force of the first and second springs, which facilitates the quick removal of the processed saw blade and the cleaning of debris, shortening the processing auxiliary time and improving production efficiency and processing continuity to a certain extent.

A horizontal rod 7 is slidably connected inside the sliding sleeve 6. One end of the horizontal rod 7 passes through the saw blade positioning frame 3 and extends into the inner cavity of the saw blade positioning frame 3. The end of the horizontal rod 7 extending into the inner cavity of the saw blade positioning frame 3 is fixedly connected... A clamping plate 8 is fixedly connected. Vertical grooves that cooperate with the clamping plate 8 are opened on both sides of the inner cavity of the saw blade positioning frame 3. A contact block 9 is fixedly connected to the other end of the crossbar 7. A first spring 10 is sleeved on the outer periphery of the crossbar 7 between the contact block 9 and the sliding sleeve 6. A fixing plate 11 is fixedly connected to the bottom end of the vertical bar 5. A second spring 12 is fixedly connected between the top of the fixing plate 11 and the bottom of the turntable 2. A column 13 is fixedly connected to one side of the top of the processing table 1. A stabilizing plate 14 is fixedly connected to the top of one side of the column 13. An arc plate 15 that cooperates with the contact block 9 is fixedly connected to both sides of the bottom of the stabilizing plate 14 through connecting rods. The outer arc surface of the arc plate 15 is a smooth surface.

[0020] Furthermore, in order to automatically press the saw blade during the operation of the drilling machine 18 and avoid drilling deviation caused by saw blade shaking, a cylinder 16 is installed at the bottom of the stabilizing plate 14. The cylinder 16 is powered by an external power source. A telescopic rod 17 is fixedly connected to the telescopic end of the cylinder 16. The drilling machine 18 is installed at the bottom of the telescopic rod 17. L-rods 19 are fixedly connected to both sides of the telescopic rod 17. A clamping plate 20 that cooperates with the clamping plate 8 is fixedly connected to the bottom of the L-rod 19.

[0021] It should be noted that the drilling machine 18 is powered by an external power source. The drilling machine 18 has a built-in power drive system. When drilling, the drill bit of the drilling machine 18 drills the saw blade at a set rotation speed and feed rate. By precisely controlling the rotation speed, feed rate and drilling depth of the drill bit, the dimensional accuracy and surface quality of the drilled installation hole meet the requirements.

[0022] Furthermore, to ensure the stability of the turntable 2 during rotation, support rods 21 are fixedly connected to both sides of the bottom of the turntable 2. Ball bearings 22 are provided at the bottom of the support rods 21, and an annular slide rail 23 that cooperates with the ball bearings 22 is provided on the top of the processing table 1.

[0023] The bottom of the processing table 1 is fixedly connected to a drive motor 24 via a connector. The drive motor 24 is powered by an external power source. The output shaft of the drive motor 24 is fixedly connected to a rotating rod 25 via a coupling. The top of the processing table 1 is provided with a through groove that cooperates with the rotating rod 25. The top of the rotating rod 25 is fixedly connected to the bottom of the turntable 2.

[0024] Furthermore, in order to facilitate processing with different saw blades, both sides of the saw blade positioning frame 3 are threaded with screws 26 through threaded holes.

The saw blade requiring the drilling of mounting holes is placed on the placement plate 4. The drive motor 24 is started, and the drive motor 24 drives the turntable 2 to rotate via rotating rod 25. When the turntable 2 rotates to the designated position, the contact block 9 contacts the arc plate 15. Under the pressure of the arc plate 15, the contact block 9 drives the clamping plate 8 to move into the saw blade positioning frame 3 via crossbar 7 until the turntable 2 drives the saw blade positioning frame 3 to rotate directly below the drilling machine 18. At the same time, the drive motor 24 stops rotating, and the cylinder 16 is started. The cylinder 16 drives the drilling machine 18 and L-rod 19 to move downward via telescopic rod 17. The L-rod 19 drives the pressure plate 20 to fit against the clamping plate 8 and press it firmly. After the saw blade is drilled, the drilling machine 18 performs drilling operations. After the installation hole at the center of the saw blade is drilled, the cylinder 16 is started to lift the drilling machine 18 and the L-bar 19 upward. Under the elastic force of the second spring 12, the clamping plate 8 moves upward away from the saw blade. The drive motor 24 is started again, the turntable 2 rotates, the contact block 9 disengages from the arc plate 15, and under the elastic force of the first spring 10, the clamping plate 8 drives the crossbar 7 to reset. The clamping plate 8 moves to the outside of the saw blade positioning frame 3. When the turntable 2 drives the processed saw blade to the auxiliary station, the processed saw blade can be taken out and the debris in the saw blade positioning frame 3 can be cleaned. At the same time, the turntable 2 drives the new saw blade to be processed to the processing station, realizing the continuous operation of saw blade processing opening.
