Description

Technical Field

[0001] This utility model belongs to the field of saw blade processing technology, specifically a saw blade tooth tip cemented carbide welding positioning device. Background Technology

[0002] In the field of metal processing, saw blades are important cutting tools. Welding carbide to the tips of saw blade teeth can significantly improve the wear resistance and cutting efficiency of saw blades. However, the positioning devices used in the current carbide welding process for saw blade teeth have many shortcomings. Traditional positioning devices often cannot accurately fix the relative position of the saw blade and the carbide, resulting in deviation of the tooth tip position after welding, which affects the cutting performance and service life of the saw blade. Moreover, when welding carbide to each tooth tip of the saw blade, the position of the saw blade needs to be adjusted. However, common positioning devices are cumbersome to adjust the position of the saw blade and have poor adjustment accuracy. Therefore, this application proposes a positioning device for carbide welding of saw blade teeth. Utility Model Content

[0014] Depend on Figures 1-6 The present invention includes a back plate 1, a movable clamping plate 2 on the front side of the back plate 1, a vertically extending clamping groove 21 extending to the right side of the top of the clamping plate 2, a first roller group at the upper position of the inner wall of the clamping groove 21, a second roller group at the lower position of the inner wall of the clamping groove 21, a first extrusion plate 27 fixedly installed at the rear side of the middle position of the inner wall of the clamping groove 21, a plate groove 28 at the front side of the middle position of the inner wall of the clamping groove 21, a second extrusion plate 29 installed in the plate groove 28, and a clamping plate 29 installed at the center of the front side of the clamping plate 2. The second hydraulic rod 210 has its telescopic end extending into the groove 28 and fixedly connected to the center of the side of the second extrusion plate 29. A storage assembly is provided on the front side of the back plate 1 and on the right side of the clamping plate 2. The clamping plate 2 is designed to be movable to accommodate saw blades of different sizes. The coordinated cooperation of the first roller group and the second roller group in the groove 21, as well as the cooperation of the first extrusion plate 27 and the second extrusion plate 29, enables precise vertical positioning of the saw blade. At the same time, a welding station is reserved for the cemented carbide. The overall structure is compact and efficient, ensuring positioning stability from the basic architecture.

[0015] like Figures 1 to 4 As shown, the first roller group includes two first rotating rollers 24. First roller grooves 22 are opened at the upper positions on both sides of the inner wall of the clamping groove 21. Fixed shafts 23 are fixedly installed in the two first roller grooves 22. The two first rotating rollers 24 are respectively rotatably sleeved on the two fixed shafts 23, and the side walls of the two first rotating rollers 24 extend into the clamping groove 21 and contact it. The second roller group includes two second rotating rollers 26. Second roller grooves 25 are provided on both sides of the inner wall of the clamping groove 21 at the lower position. The two second rotating rollers 26 are rotatably installed in the two second roller grooves 25 respectively, and the side walls of the two second rotating rollers 26 extend into the clamping groove 21 and make contact. The rotating shafts at the left ends of the two second rotating rollers 26 pass through the clamping plate 2 and extend to its left side. An adjustment component 6 is provided between the rotating shafts at the left ends of the two second rotating rollers 26. The first roller group and the second roller group adopt a rotating design. Through the rolling contact between the roller surface and the saw blade, the friction during clamping can be reduced, which can not only stably support the saw blade, but also avoid surface scratch damage.

[0016] like Figure 1 and Figure 5 As shown, the adjustment assembly 6 includes two gears 61 and a handle 62. The two gears 61 are respectively fixedly installed on the rotating shafts at the left ends of the two second rotating rollers 26, and the side walls of the two gears 61 are meshed together. The handle 62 is installed at the axis of the outer gear 61. The adjustment assembly 6 uses the meshing transmission principle of the gears 61 to realize the synchronous and equidistant adjustment of the second rotating rollers 26 through the handle 62, so as to ensure the consistency and accuracy of the saw blade posture adjustment.

[0017] like Figure 1 and Figure 6 As shown, the storage assembly includes a fixing bolt 71, a storage plate 72, a support plate 73, a third hydraulic rod 74, and a support rod 75. The fixing bolt 71 is fixedly installed on the front side of the back plate 1. The left end of the storage plate 72 is rotatably sleeved on the fixing bolt 71. The support plate 73 is installed on the front side of the back plate 1 and located below the storage plate 72. A storage groove is opened at the center of the top of the support plate 73. The third hydraulic rod 74 is installed in the storage groove. The support rod 75 is installed on the output end of the third hydraulic rod 74 and abuts against the bottom of the storage plate 72. The rotatable storage plate 72 in the storage assembly can realize multi-angle adjustment of the placement angle of the cemented carbide, which can meet the requirements of different welding processes for the tilt of the cemented carbide. The precise drive of the third hydraulic rod 74 ensures the stability of the placement angle and avoids the cemented carbide sliding and shifting during the welding process.

[0018] like Figure 6As shown, the support rod 75 is configured as a tilting J-shape, and a slot 76 is provided on the front side of the shelf 72. The bent part of the support rod 75 is located on the front side of the shelf 72, and the bent end of the support rod 75 is movably inserted into the slot 76. Positioning rods 77 are fixedly connected to both ends of the bottom of the support rod 75. Both ends of the top of the support plate 73 are provided with through openings that pass through vertically. The two positioning rods 77 are respectively inserted into the corresponding through openings. The combination design of the J-shaped support rod 75, the slot 76, and the positioning rods 77 forms a mechanical limiting and locking structure, which enhances the reliability of the angle fixation of the shelf 72.

[0019] like Figure 1 and Figure 2 As shown, two guide rods 4 are installed on the front side of the back plate 1. The top and side of the clamping plate 2 are provided with through holes 3 that run from left to right. The two through holes 3 on the clamping plate 2 are respectively movably fitted onto the two guide rods 4. A first hydraulic rod 5 is installed on the front side of the back plate 1 and on the left side of the clamping plate 2. The telescopic end of the first hydraulic rod 5 is fixedly connected to the center of the left side of the clamping plate 2. The linkage design of the guide rods 4 and the first hydraulic rod 5 provides stable guidance and power source for the clamping plate 2, ensuring that the clamping plate 2 moves without shaking, realizing precise adjustment of the saw blade clamping position. The hydraulic drive responds quickly, which greatly shortens the clamping time compared with manual adjustment and significantly improves production efficiency.
