Description

Technical Field

[0001] The utility model relates to the technical field of saw blades, in particular to a saw blade center hole reaming device with a positioning structure. Background Art

[0002] Saw blade is a general term for thin circular cutting tools used to cut solid materials. In order to facilitate installation, it is usually necessary to open a hole in the center of the saw blade.

[0003] The existing patent document announcement number CN20212253110 is specifically a hole-punching device for circular saw blade production, including a base plate, a vertical plate symmetrically fixed on the top of the base plate, two support plates fixed on one side wall of the vertical plate, and a bidirectional threaded rod provided on one side of the vertical plate. By setting a bidirectional threaded rod, an arc plate, a first bevel gear, a second bevel gear, a rotating rod and a clamping mechanism, circular saw blades of different sizes can be clamped and fixed in the arc plate, and the center of the circle of the circular saw blades of different sizes is consistent with the axis of the punching mechanism, thereby improving the accuracy of the hole-punching. By setting the punching mechanism, a positioning hole can be opened at the same time as the inner hole is opened, thereby improving the production efficiency of the circular saw blade while saving time and effort in use.

[0004] However, the device clamps and fixes the edge of the saw blade through a clamping mechanism, and does not have a structure to fix the middle position of the saw blade. For particularly thin saw blades, deformation will occur during the punching process, thereby affecting the punching accuracy. In addition, there are burrs on the center hole of the punched saw blade, which can easily scratch the hands of the staff and the appearance of the saw blade. The device is unable to grind and polish the center hole of the saw blade and the outer edge of the hole. It is now necessary to improve the existing device to meet actual needs. Utility Model Content

[0005] (1) Technical problems solved

[0006] In response to the deficiencies in the prior art, the present invention provides a saw blade center hole reaming device with a positioning structure, which has the function of placing the saw blade flat on the top surface of the filter plate as a whole, ensuring that the filter plate can provide all-round and stable support to the saw blade during the center reaming of the saw blade, avoiding deformation of the saw blade during the punching process due to improper clamping, and pushing the slide plate to drive the compaction plate to move linearly to compact and fix the two ends of the saw blade, so that the entire saw blade can be compressed and positioned on the top surface of the filter plate, thereby avoiding deformation of the saw blade due to improper fixation during the reaming process, thereby ensuring that the saw blade is subjected to uniform force while improving the integrity of the saw blade, thereby solving the above-mentioned technical problems.

[0007] (2) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a saw blade center hole reaming device with a positioning structure, comprising a processing table, a fixed seat is provided on the top surface of the processing table, a reamer is provided on the bottom surface of the fixed seat, a dust cover is provided on the side surface of the processing table, positioning plates are provided at both ends of the processing table, positioning frames are provided at both ends of the top surface of the processing table, extension plates are provided at both ends of the positioning frame, a slide plate is provided on the top surface of the extension plate, a compacting plate is provided on the bottom surface of the slide plate, a filter plate is provided on the inside of the positioning frame, a center line is provided on the top surface of the positioning frame, a grinding groove is provided on the front surface of the positioning frame, a support plate is provided on the bottom surface of the positioning frame, a spare plate is provided between the support plates, and a rubber plate is provided on the bottom surface of the support plate.

[0009] Preferably, both ends of the top surface of the processing table are fixedly connected to the fixing seats, and the bottom surface of the fixing seats is fixedly connected to the chassis, the inner side of the chassis is fixedly connected to the motor, and the output end of the motor is fixedly connected to the reamer, the positioning frame is located at the bottom surface of the chassis, and a limiting slot is provided on the inner side of the positioning frame.

[0010] Through the above technical solution, the saw blade is placed statically in the center groove of the top surface of the filter plate, and then the slide plate is pushed to drive the compaction plate to move linearly to compact and fix the two ends of the saw blade respectively. At the same time, the saw blade is placed flat on the top surface of the filter plate as a whole, which can ensure that the filter plate can fully support the saw blade during the center reaming of the saw blade, avoiding deformation during the punching process caused by improper clamping of the side ends of the saw blade, thereby effectively improving the accuracy of the saw blade punching. At the same time, the debris generated during the reaming process falls directly into the material receiving frame at the bottom end of the inner side of the positioning frame, preventing the debris from falling on the top surface of the processing table and requiring the operator to spend time cleaning it separately, thereby effectively improving work efficiency. After the saw blade is reamed, it is taken out directly from the inside of the grinding groove, and the upper and lower ends of the groove are fixedly connected to the grinding plates respectively. The grinding plate is in direct contact with the saw blade and can smooth out the burrs on its side ends, thereby effectively improving the flatness and aesthetics of the saw blade.

[0011] Preferably, the extension plates are fixedly mounted at both ends of the positioning frame, and a slide groove is provided on the top surface of the extension plates. The slide plate is located on the top surface of the slide groove, and the extension plates are connected to the positioning frame. The compaction plates pass through the extension plates and the side ends of the positioning frame respectively.

[0012] Through the above technical solution, stabilizing plates are fixedly connected at both ends of the top surface of the processing table, and the stabilizing plates and the positioning frame are fixedly connected by an electric telescopic rod. After the saw blade is clamped, the electric telescopic rod is used to drive the positioning frame to move upward, and its reamer is brought into contact with the center point of the saw blade. After that, the motor switch can be started to ream the saw blade, and the electric telescopic rod is started a second time to drive the positioning frame to move downward. This can prevent the operator from accidentally touching the reamer and causing damage to his skin during the cutting process of the saw blade, thereby effectively improving the safety of the device.

[0013] Preferably, the compacting plate and the slide plate are connected by a vertical plate, and the compacting plate is located on the top surface of the filter plate. A center groove is opened in the center of the top surface of the filter plate, and the center groove corresponds to the reamer. The support plates are located at both ends of the bottom surface of the positioning frame.

[0014] Through the above technical solution, the saw blade is placed flat on the top surface of the filter plate as a whole, and the filter plate can ensure that the filter plate can provide all-round and stable support to the saw blade during the center reaming of the saw blade, thereby avoiding deformation of the saw blade during the drilling process due to improper clamping. The slide plate is pushed to drive the compaction plate to move linearly to compact and fix the two ends of the saw blade, and the entire saw blade can be pressed and positioned on the top surface of the filter plate, thereby avoiding deformation of the saw blade due to improper fixation during the reaming process, thereby ensuring uniform force on the saw blade and improving the integrity of the saw blade to avoid economic losses.

[0015] Preferably, a material receiving frame is provided inside the positioning frame, and a discharge pipe is fixedly connected to the bottom surface of the positioning frame. The discharge pipe passes through the material receiving frame and the positioning frame respectively, and the filter plate corresponds to the grinding groove.

[0016] Through the above technical solution, after the center hole of the saw blade is reamed, the saw blade is pulled out from the inner side of the grinding groove, and the grinding plates are fixedly connected to the two ends of the inner wall of the grinding groove. When the operator pulls the saw blade out from the inner side of the grinding groove, the burrs on the side end of the saw blade can be smoothed by contact with the grinding plate, avoiding scratches caused by contact with the operator or affecting the appearance of the saw blade. Therefore, the grinding work can be carried out directly after the center hole is completed, and the operator does not need to take the saw blade to the grinding device for grinding separately. It can effectively reduce the difficulty of the work and save time and effort.

[0017] Compared with the prior art, the present invention provides a saw blade center hole reaming device with a positioning structure, which has the following beneficial effects:

[0018] 1. The utility model places the saw blade flat on the top surface of the filter plate as a whole, and can ensure that the filter plate can provide all-round and stable support to the saw blade during the process of center reaming of the saw blade, avoiding deformation of the saw blade during the drilling process due to improper clamping, and pushing the slide plate to drive the compacting plate to move linearly to compact and fix the two ends of the saw blade, which can compress and position the entire saw blade on the top surface of the filter plate, thereby avoiding deformation of the saw blade due to improper fixation during the reaming process, thereby ensuring uniform force on the saw blade, and improving the integrity of the saw blade to avoid economic losses.

[0019] 2. The utility model pulls out the saw blade from the inner side of the grinding groove after completing the center reaming of the saw blade, and fixes grinding plates at both ends of the inner wall of the grinding groove. When the operator pulls out the saw blade from the inner side of the grinding groove, the burrs on the side ends of the saw blade can be smoothed by contact with the grinding plate, avoiding scratches caused by contact with the operator or affecting the appearance of the saw blade. Then, the grinding work can be carried out directly after completing the center reaming, and the operator does not need to take the saw blade to the grinding device for grinding work separately.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-3 A device for reaming a center hole of a saw blade with a positioning structure includes a processing table 1, a fixed seat 2 is provided on the top surface of the processing table 1, a reamer 3 is provided on the bottom surface of the fixed seat 2, a dust cover 4 is provided on the side of the processing table 1, positioning plates 5 are provided at both ends of the processing table 1, positioning frames 6 are provided at both ends of the top surface of the processing table 1, extension plates 7 are provided at both ends of the positioning frame 6, a slide plate 8 is provided on the top surface of the extension plate 7, a compacting plate 9 is provided on the bottom surface of the slide plate 8, a filter plate 10 is provided on the inside of the positioning frame 6, a center line 11 is provided on the top surface of the positioning frame 6, a grinding groove 12 is provided on the front surface of the positioning frame 6, a support plate 13 is provided on the bottom surface of the positioning frame 6, a spare plate 14 is provided between the support plates 13, and a rubber plate 15 is provided on the bottom surface of the support plate 13.

[0026] Specifically, the two ends of the top surface of the processing table 1 are fixedly connected to the fixing seat 2, and the bottom surface of the fixing seat 2 is fixedly connected to the chassis, the inner side of the chassis is fixedly connected to the motor, and the output end of the motor is fixedly connected to the reamer 3, the positioning frame 6 is located at the bottom surface of the chassis, and a limiting groove is provided on the inner side of the positioning frame 6. The advantage is that the saw blade is placed in the center groove of the top surface of the filter plate 10, and then the slide plate 8 is pushed to drive the compacting plate 9 to move linearly to compact and fix the two ends of the saw blade respectively. At the same time, the saw blade is placed flat on the top surface of the filter plate 10 as a whole, which can ensure that the filter plate 10 can fully support the saw blade during the center reaming of the saw blade, avoiding deformation during the punching process caused by improper clamping of the side ends of the saw blade, thereby effectively improving the accuracy of the saw blade punching. At the same time, the debris generated during the reaming process falls directly into the material receiving frame at the bottom end of the inner side of the positioning frame 6, preventing the debris from falling on the top surface of the processing table 1 and requiring the operator to spend time cleaning it separately, thereby effectively improving work efficiency. After the saw blade is reamed, it is taken out directly from the inner side of the grinding groove 12, and the upper and lower ends in the groove are fixedly connected to the grinding plates, which are in direct contact with the saw blade and can grind off the burrs on its side ends, thereby effectively improving the flatness and aesthetics of the saw blade.

[0027] Specifically, the extension plates 7 are fixedly mounted on both ends of the positioning frame 6, and a slide groove is provided on the top surface of the extension plates 7. The slide plate 8 is located on the top surface of the slide groove, and the extension plates 7 and the positioning frame 6 are connected. The compacting plates 9 pass through the extension plates 7 and the side ends of the positioning frame 6. The advantage is that the stabilizing plates are fixedly connected to both ends of the top surface of the processing table 1, and the stabilizing plates and the positioning frame 6 are fixedly connected via an electric telescopic rod. After the saw blade is clamped, the electric telescopic rod is used to drive the positioning frame 6 to move upward, so that its reamer contacts the center point of the saw blade. After that, the motor switch can be activated to ream the saw blade. The electric telescopic rod is activated a second time to drive the positioning frame 6 to move downward. This can prevent the operator from accidentally touching the reamer 3 and causing damage to their skin during the saw blade cutting process, thereby effectively improving the safety of the device.

[0028] Specifically, the compacting plate 9 is connected to the slide plate 8 via a vertical plate, and the compacting plate 9 is located on the top surface of the filter plate 10. A center groove is provided in the center of the top surface of the filter plate 10, and the center groove corresponds to the reamer 3. The support plates 13 are located at both ends of the bottom surface of the positioning frame 6. The advantage is that the saw blade is placed flat on the top surface of the filter plate 10 as a whole, ensuring that the filter plate 10 can provide all-round and stable support for the saw blade during the center reaming of the saw blade, thereby preventing deformation of the saw blade during the drilling process due to improper clamping. The slide plate 8 is pushed separately to drive the compacting plate 9 to move linearly to compact and fix the two ends of the saw blade, so that the entire saw blade can be pressed and positioned on the top surface of the filter plate 10, thereby preventing deformation of the saw blade due to improper fixation during the reaming process. This ensures that the saw blade is evenly stressed, improves the integrity of the saw blade, and avoids economic losses.

[0029] Specifically, a material receiving frame is provided inside the positioning frame 6, and a material discharging pipe is fixedly connected to the bottom surface of the positioning frame 6. The material discharging pipe passes through the material receiving frame and the positioning frame 6 respectively, and the filter plate 10 corresponds to the grinding groove 12. The advantage is that after the saw blade center hole is completed, the saw blade is pulled out from the inside of the grinding groove 12, and grinding plates are fixedly connected to the two ends of the inner wall of the grinding groove 12. When the operator pulls the saw blade out of the grinding groove 12, the burrs on the side ends of the saw blade can be smoothed by contact with the grinding plate, avoiding scratches caused by contact with the operator or affecting the appearance of the saw blade. Therefore, the grinding work can be carried out directly after the center hole is completed, without the operator having to take the saw blade to the grinding device for grinding work. It can effectively reduce the difficulty of the work and has the effect of saving time and labor.

[0030] During use, the saw blade is placed in the center groove of the top surface of the filter plate 10, and then the slide plate 8 is pushed to drive the compacting plate 9 to move linearly to compact and fix the two ends of the saw blade respectively. At the same time, the saw blade is placed flat on the top surface of the filter plate 10 as a whole, which can ensure that the filter plate 10 can fully support the saw blade during the center reaming of the saw blade, avoiding deformation during the punching process caused by improper clamping of the side end of the saw blade, thereby effectively improving the accuracy of the saw blade punching. At the same time, the debris generated during the reaming process falls directly into the material receiving frame at the bottom end of the inner side of the positioning frame 6, preventing the debris from falling on the top surface of the processing table 1 and requiring the operator to spend time to clean it separately, thereby effectively improving work efficiency. After the saw blade is reamed, it is directly removed from the grinding wheel. The inner side of the groove 12 is taken out, and the upper and lower ends of the groove are fixedly connected to the grinding plates respectively. The grinding plates are in direct contact with the saw blade and can grind off the burrs on its side ends, thereby effectively improving the flatness and aesthetics of the saw blade. The stabilizing plates are fixedly connected to the two ends of the top surface of the processing table 1, and the stabilizing plates and the positioning frame 6 are fixedly connected through an electric telescopic rod. After the saw blade is limited and clamped, the positioning frame 6 is driven upward by the electric telescopic rod to contact its reamer with the center point of the saw blade. After that, the motor switch can be started to ream the saw blade, and the electric telescopic rod is started a second time to drive the positioning frame 6 to move downward. This can prevent the operator from accidentally touching the reamer 3 and causing damage to his skin during the cutting process of the saw blade, thereby effectively improving the safety of the device.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
