Description

Technical Field

[0001] The utility model relates to the technical field of saw blade production, in particular to a positioning device for saw blade production. Background Art

[0002] A saw blade is a tool used to cut wood, metal or other materials. A saw blade is usually a long metal strip with a series of sharp teeth on it. The shape and arrangement of the teeth vary depending on the material to be cut. A hand saw blade is usually made of high-carbon steel or alloy steel. The workpiece is cut by manually moving it back and forth. When producing saw blades, it is necessary to precisely control processes such as material selection, heat treatment, cutting and forming, grinding and polishing to ensure that the saw blade has good cutting performance, wear resistance and stability. Since the saw blade has small defects after processing, the staff will use tools to trim the workpiece. Therefore, it is necessary to position the workpiece stably.

[0003] In the related art, during the saw blade trimming process, the saw blade is generally clamped, positioned and stabilized with the help of a clamping table, and then the clamped and stabilized saw blade is trimmed for use.

[0004] However, currently in the process of saw blade trimming, since the clamping table can only clamp the saw blade at a single position, when the saw blade needs to be trimmed at multiple positions and different surfaces, it is necessary to use different clamping tables, which makes the saw blade clamping and positioning inconvenient and affects the convenience and flexibility of the saw blade clamping and positioning.

[0036] Specifically, the working process or working principle of the positioning device for saw blade production is as follows: when in use, when the saw blade workpiece needs to be vertically positioned and stabilized, the saw blade workpiece is placed on the inner side of the pressure plate 3 and the support plate 2, and the saw blade workpiece is made to fit the support plate 2, and then the screw rod 5 is rotated to cooperate with the screw hole 7 and the force seat 6 to apply a thrust to the translation frame 4, so that the translation frame 4 pushes the pressure plate 3 to clamp and position the saw blade workpiece against the support plate 2, and at the same time, the connecting seat 9 follows the screw rod 5 to rotate inside the connecting groove 8 to rotate between the screw 5 and the translation frame 4 During the connection work, when the saw blade workpiece needs to lie flat on the top of the base 1 for positioning and stabilization, the saw blade workpiece is laid flat on the top of the base 1, and the saw blade is aligned with the backing plate 2. Then, the handheld pressing frame 10 drives the screw handle 13 to rise through the screw mouth 12 to make the positioning column 11 higher than the backing plate 2. At this time, the lifting rod 15 moves inside the lifting groove 14 to perform lifting and connecting work between the rotating seat 17 and the screw handle 13. At the same time, the limit block 19 moves inside the limit groove 18 to perform lifting and limiting work between the screw handle 13 and the lifting rod 15. First, turn the pressing frame 10 to move the screw handle 13 upward through the screw mouth 12 to make the positioning column 11 higher than the backing plate 2. The frame 10 drives the positioning column 11 to move to the front side of the back plate 2, and then the screw handle 13 is held by hand to drive the positioning column 11 to move downward through the screw mouth 12, and the positioning rod 21 is held by hand and pulled to the rear side to enter the inside of the positioning hole 20. At this time, the stop bar 24 moves inside the stop mouth 23 to perform active limiting work between the positioning hole 20 and the positioning rod 21. At the same time, the spring 25 is affected by the moving force of the positioning rod 21 and contracts. When the bottom of the screw handle 13 contacts the top of the base 1, it means that the positioning hole 20 is aligned with the positioning groove 22, and then the spring 25 of the positioning rod 21 is released. A thrust is applied to the positioning rod 21 through the blocking bar 24, so that the positioning rod 21 enters the positioning groove 22 to insert and position the lifting rod 15 and the screw handle 13. Then, the screw barrel is rotated to cooperate with the screw mouth 12 to apply a downward thrust to the positioning column 11 through the lower pressure frame 10, so that the positioning column 11 presses down and positions the saw blade workpiece lying flat on the top of the base 1 and aligned with the back plate 2. At the same time, the rotating seat 17 rotates in the rotating groove 16 following the lifting rod 15 and the screw handle 13, so as to stabilize the rotation of the lifting rod 15 and the screw handle 13.
