Technical Field
[0001] This utility model relates to the field of band saw blade processing technology, and more specifically, to a band saw blade tooth pushing device. Background Technology
[0002] In existing technologies, band saw blade processing requires grinding the weld points welded to the saw teeth. During the grinding process, the band saw blade needs to be clamped so that it can push one tooth at a time for grinding. Existing band saw blade tooth-pushing clamping devices use two bearings to clamp the band saw blade, and the two bearings are locked together by bolts. After the bolts are locked, the resistance to the band saw blade is too great, which makes it difficult to push the teeth. Moreover, it is very difficult to loosen the bearings each time. Therefore, a technical solution is needed to solve the above problems. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art, facilitate the clamping and releasing of the saw blade, and provide a band saw blade pusher device.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] This utility model discloses a band saw blade pushing device, including a clamping device and a pushing assembly. The clamping device includes a bracket, a clamping assembly, and a grinding table. At least two clamping assemblies are provided. The grinding table is installed on the bracket, and the two clamping assemblies are respectively located at both ends of the grinding table. The saw blade passes through the grinding table and the clamping assembly. The clamping assembly includes a first clamping block, a second clamping block, and a guide rod. Bearings are installed at the upper ends of the first clamping block and the second clamping block. The saw blade passes between the two bearings. The guide rod passes through the first clamping block, the second clamping block, and the bracket. A pull rod is installed at one end of the guide rod. The pull rod is hinged to the guide rod. Rotating the pull rod can bring the first clamping block and the second clamping block closer to each other. The pushing assembly includes a pushing arm. The pushing arm swings and pushes the saw blade forward.
[0006] Furthermore, the first clamping block and the second clamping block are respectively located on both sides of the bracket. The lower end of the first clamping block is provided with a guide groove, and the lower end of the second clamping block is provided with a guide strip that is inserted into the guide groove. The guide strip is located below the bracket.
[0007] Furthermore, the clamping assembly includes a first stop and a second stop. The first stop is fixedly installed at the end of the guide rod away from the pull rod, and the second stop is located between the second clamping block and the pull rod. The pull rod abuts against the end face of the second stop away from the second clamping block.
[0008] Furthermore, an elastic element is installed between the first stop block and the first clamping block, and an elastic element is installed between the second stop block and the second clamping block, wherein the elastic element is made of rubber.
[0009] Furthermore, the pull rod includes a first abutment surface and a second abutment surface, the first abutment surface and the second abutment surface are adjacent, the distance between the first abutment surface and the center of the hinge point of the pull rod is less than the distance between the second abutment surface and the center of the hinge point of the pull rod, and when the second abutment surface abuts against the second stop block, the two bearings clamp the saw blade.
[0010] Furthermore, the pusher assembly includes a mounting platform and a cylinder. The mounting platform is connected to a rotating shaft, and the cylinder drives the rotating shaft to rotate. The pusher arm is mounted on the mounting platform, and the end of the pusher arm away from the mounting platform is close to the grinding table. The saw teeth of the saw blade extend out of the upper surface of the grinding table.
[0011] Furthermore, a notch is formed at one end of the push arm near the gear grinding table, and a push rod is mounted on the push arm, with the push rod passing through the notch.
[0012] Furthermore, the bracket is equipped with an inlet guide and an outlet guide, which are located on the side of the two clamping assemblies at the farthest ends away from the gear grinding table.
[0013] The beneficial effects of this utility model are:
[0014] In this embodiment, the bearing can be quickly clamped or released from the saw blade by rotating the pull rod, which is quick and convenient to use. When the bearing clamps the saw blade, due to the setting of the elastic element, there is a certain buffer space between the bearing and the saw blade, and the push tooth assembly can better push the saw blade.

[0019] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] like Figures 1-3 As shown, this embodiment discloses a band saw blade tooth pushing device, including a clamping device 1 and a tooth pushing assembly 2. The clamping device 1 includes a bracket 11, a clamping assembly 12, and a grinding table 13. The bracket 11 extends along the length and conveying direction of the saw blade 101. The saw teeth 102 of the saw blade 101 face upwards. Part of the saw teeth 102 of the saw blade 101 extends out of the upper end face of the grinding table 13. The grinding wheel 103 is located above the grinding table 13. The grinding wheel 103 can move up and down to grind one saw tooth 102 below each time.
[0021] The pusher assembly 2 includes a pusher arm 21, a mounting platform 23, and a cylinder 24. The mounting platform 23 is connected to a rotating shaft 231. The cylinder 24 drives the rotating shaft 231 to rotate. The cylinder 24 drives the rotating shaft 231 to reciprocate through a connecting rod or gear. The pusher arm 21 is mounted on the mounting platform 23. The pusher arm 21 can swing with the reciprocating rotation of the mounting platform 23. The end of the pusher arm 21 away from the mounting platform 23 is close to the grinding table 13. A notch 211 is opened at the end of the pusher arm 21 close to the grinding table 13. A push rod 22 is mounted on the pusher arm 21. The saw blade 101 is set vertically, and the push rod 22 extends horizontally. The push rod 22 passes through the notch 211. The pusher arm 21 swings and pushes the saw blade 101 forward. During the swinging process, the saw tooth 102 enters the notch 211 and is blocked by the push rod 22. The pusher arm 21 continues to swing, causing the push rod 22 to push a saw tooth 102 forward.
[0022] At least two clamping assemblies 12 are provided. The grinding table 13 is installed on the bracket 11. The saw blade 101 passes through the grinding table 13 and the clamping assemblies 12. The two clamping assemblies 12 are located at both ends of the grinding table 13, which can keep the saw blade 101 stable when passing through the grinding table 13 and grinding.
[0023] The bracket 11 is equipped with an inlet guide table 14 and an outlet guide table 15. The inlet guide table 14 and the outlet guide table 15 are located on the side of the two clamping components 12 at the two ends away from the grinding table 13. Both the inlet guide table 14 and the outlet guide table 15 are provided with a strip groove for the saw blade 101 to pass through. Since the saw blade 101 is in a coiled state before entering the clamping component 12 and after leaving the clamping component 12, the inlet guide table 14 and the outlet guide table 15 can better guide the saw blade 101 to keep it in a straight line.
[0024] The clamping assembly 12 includes a first clamping block 122, a second clamping block 123, and a guide rod 124. Bearings 121 are installed at the upper ends of both the first clamping block 122 and the second clamping block 123. The saw blade 101 passes between the two bearings 121. The guide rod 124 passes through the first clamping block 122, the second clamping block 123, and the bracket 11. The first clamping block 122 and the second clamping block 123 are located on both sides of the bracket 11. The first clamping block 122 and the second clamping block 123 can slide along the guide rod 124. The lower end of the first clamping block 122 is provided with a guide groove 1221. The lower end of the second clamping block 123 is provided with a guide bar 1231 that is inserted into the guide groove 1221. The guide bar 1231 is located below the bracket 11. The guide groove 1221 and the guide bar 1231 limit the position of the first clamping block 122 and the second clamping block 123, keeping the two bearings 121 at the top of the first clamping block 122 and the second clamping block 123 aligned.
[0025] The clamping assembly 12 includes a first stop 125 and a second stop 126. The first stop 125 is fixedly installed on the end of the guide rod 124 away from the pull rod 128. The second stop 126 is located between the second clamping block 123 and the pull rod 128. The pull rod 128 abuts against the end face of the second stop 126 away from the second clamping block 123. An elastic element 127 is installed between the first stop 125 and the first clamping block 122, and between the second stop 126 and the second clamping block 123. The elastic element 127 is made of rubber. The elastic element 127 is provided with an annular groove, which has a certain elastic deformation capacity. When the pull rod 128 is pulled, it can compress the two elastic elements 127. The two elastic elements 127 press against the first clamping block 122 and the second clamping block 123 respectively, so that the two bearings 121 can clamp the saw blade 101. At the same time, the elastic element 127 can provide a buffer space for the clamping force of the two bearings 121, so that the two bearings 121 will not clamp the saw blade 101 too tightly, and the push arm 21 can better push the saw teeth 102.
[0026] A pull rod 128 is installed at one end of the guide rod 124. The pull rod 128 is hinged to the guide rod 124. Rotating the pull rod 128 can bring the first clamping block 122 and the second clamping block 123 closer together. The pull rod 128 includes a first abutment surface 1281 and a second abutment surface 1282. The first abutment surface 1281 and the second abutment surface 1282 are adjacent. The distance between the center of the first abutment surface 1281 and the center of the hinge point of the pull rod 128 is less than the distance between the center of the second abutment surface 1282 and the center of the hinge point of the pull rod 128. By rotating the pull rod 128, the first abutment surface of the pull rod 128... The first abutment 1281 or the second abutment 1282 can abut against the second stop 126. When the first abutment 1281 abuts against the second stop 126, the pressure deformation force on the two elastic elements 127 is small, and the clamping force of the two bearings 121 on the saw blade 101 is small. The saw blade 101 can be taken out or placed between the two bearings 121. When the second abutment 1282 abuts against the second stop 126, the two bearings 121 clamp the saw blade 101, and the pressure deformation force on the two elastic elements 127 reaches the maximum. The two bearings 121 can clamp the saw blade 101 tightly.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
