Description

Technical Field

[0001] The utility model relates to the technical field of production of guide devices, in particular to a roller-type saw belt guide device which can be swung and adjusted. Background Art

[0002] A band saw machine needs to use a band saw blade guide device when in use. At present, ordinary band saw machines on the market generally use a clamp-type saw blade guide device, and ordinary high-speed band saw machines generally use a rolling bearing type saw blade guide device.

[0003] Among them, the rolling bearing type saw band guide device generates very little heat due to the rolling friction between the bearing and the band saw blade, which does not affect the life of the tool, so it can guide the operation of ordinary high-speed band saw blades (linear speed <1500m / min). However, since the standard bearing diameter is not large and the rotation speed is too high, the bearing life is shortened. Therefore, this structure is not very suitable for the high-speed band saw blade guidance of aluminum cutting (linear speed >1500m / min). For this reason, we propose a swingable and adjustable roller type saw band guide device. Utility Model Content

[0004] The utility model aims to provide a swingable and adjustable roller saw belt guide device to solve the problem in the background technology that the standard bearing has a small diameter and the rotation speed is too high, which leads to a shortened bearing life.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a swingable and adjustable roller-type saw band guide device, comprising a mounting support plate, a guide assembly, the guide assembly is used to limit the vibration of the band saw blade, the guide assembly is arranged in the mounting support plate, a connecting assembly, the connecting assembly is used to replace the guide assembly, and the connecting assembly is installed in the guide assembly;

[0006] The two guiding assemblies include a swing seat, which is sleeved in a mounting support plate, a connecting rod is installed in the swing seat, and the connecting rod is rotatably connected to the swing seat through a bearing, a fixed plate is fixedly connected to the connecting rod, a guide wheel with an edge is sleeved on the fixed plate located above, and a guide wheel without an edge is sleeved on the fixed plate located below.

[0007] Preferably, a threaded pin is sleeved in the swing seat, the threaded pin is fixedly connected to the mounting support plate, and a nut is threadedly connected to the threaded pin.

[0008] Preferably, a base is fixedly connected to the mounting support plate, and a slide groove is provided in the base.

[0009] Preferably, a positioning pin is sleeved in the slide groove.

[0010] Preferably, a reinforcing rib is fixedly connected to the base, and the reinforcing rib is fixedly connected to the mounting support plate.

[0011] Preferably, the two connecting components include a threaded barrel, the threaded barrel is fixedly connected to a fixed plate, a bolt is threadedly connected in the threaded barrel, a pressure plate is sleeved on the outer wall of the bolt, and an insertion rod is fixedly connected in the pressure plate.

[0012] Preferably, a rubber pad is fixedly connected to the pressure plate, and the rubber pad is sleeved on the outer wall of the bolt.

[0013] Preferably, the insert rod is processed into a rectangular column shape.

[0014] The utility model has at least the following beneficial effects:

[0015] The utility model can limit the vibration of the band saw blade through the guide assembly, and the guide assembly is convenient to replace through the connecting assembly. In the guide assembly, the band saw blade passes through the gap between the guide wheel with edge and the guide wheel without edge when working. The guide wheel with edge and the guide wheel without edge both drive the fixed plate and the connecting rod to rotate in the swing seat through the bearing. In this embodiment, the guide wheel with edge can limit the back of the band saw blade, and the guide wheel with edge and the guide wheel without edge limit the vibration of the band saw blade from the left and right sides of the band saw blade, so as to realize the high-speed guide operation of the band saw blade. The swing seat is installed on the mounting support plate, and the side surfaces of the guide wheel with edge and the guide wheel without edge are close to the band saw blade through the eccentricity. The side of the saw blade can achieve natural guiding. When the guide wheel with edge and the guide wheel without edge are worn, compensation can be achieved by adjusting the swing seat. The band saw blade is guided by the guide wheel with edge and the guide wheel without edge. The diameters of the guide wheel with edge and the guide wheel without edge are larger, so the higher speed of the band saw blade is transmitted to the speed of the guide wheel with edge and the guide wheel without edge. It will not be too high, and the speed of the corresponding bearings is also reduced, and the service life is greatly extended. The use of bolts facilitates the installation and disassembly of the guide wheel with edge and the guide wheel without edge. The insertion rod limits the use position of the guide wheel with edge and the guide wheel without edge, ensuring the stability of the guide wheel with edge and the guide wheel without edge during operation.

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] The rolling bearing type saw band guide device generates very little heat due to the rolling friction between the bearing and the band saw blade, which does not affect the life of the tool. Therefore, it can guide the ordinary high-speed band saw blade (linear speed <1500m / min). However, since the standard bearing diameter is not large and the rotation speed is too high, the bearing life is shortened. Therefore, this structure is not suitable for the high-speed band saw blade guidance of aluminum cutting (linear speed >1500m / min). For this reason, we propose a swingable and adjustable roller type saw band guide device.

[0028] The swingable roller saw band guide device of the present embodiment can limit the vibration of the band saw blade through the guide assembly 1, and the guide assembly 1 can be easily replaced through the connecting assembly 2. In the guide assembly 1, the band saw blade passes through the gap between the edge guide wheel 8 and the edgeless guide wheel 9 when working. The edge guide wheel 8 and the edgeless guide wheel 9 both drive the fixed plate 7 and the connecting rod 5 to rotate in the swing seat 4 through the bearing 6. In the present embodiment, the edge guide wheel 8 can limit the back of the band saw blade, and the edge guide wheel 8 and the edgeless guide wheel 9 limit the vibration of the band saw blade from the left and right sides of the band saw blade, so as to realize the high-speed guiding operation of the band saw blade. The swing seat 4 is installed on the mounting support plate 3, and the edge guide wheel 8 and the edgeless guide wheel 9 are eccentrically adjusted. The side of the wheel 9 is close to the side of the band saw blade to achieve natural guiding. When the edge guiding wheel 8 and the edgeless guiding wheel 9 are worn, compensation can be achieved by adjusting the swing seat 4. The band saw blade is guided by the edge guiding wheel 8 and the edgeless guiding wheel 9. The edge guiding wheel 8 and the edgeless guiding wheel 9 have larger diameters, so the higher band saw blade running speed transmitted to the rotation speed of the edge guiding wheel 8 and the edgeless guiding wheel 9 will not be too high, and the corresponding rotation speed of the bearing 6 is also reduced, and the service life is greatly extended. The use of the bolt 17 facilitates the installation and disassembly of the edge guiding wheel 8 and the edgeless guiding wheel 9. The insertion rod 19 limits the use position of the edge guiding wheel 8 and the edgeless guiding wheel 9 to ensure the stability of the edge guiding wheel 8 and the edgeless guiding wheel 9 during operation.

The upper fixed plate 7 is provided with a guide wheel 8 with an edge, and the lower fixed plate 7 is provided with a guide wheel 9 without an edge. When the band saw blade is working, the band saw blade moves from the edge The guide wheel 8 passes through the gap between the guide wheel 8 and the guide wheel without edge 9. Both the guide wheel 8 and the guide wheel without edge 9 drive the connecting rod 5 to rotate through the fixed plate 7. The connecting rod 5 rotates in the swing seat 4 through the bearing 6. In this embodiment, the guide wheel 8 with edge can limit the back of the band saw blade, and the guide wheel 8 with edge and the guide wheel without edge 9 limit the shaking of the band saw blade from the left and right sides of the band saw blade to achieve high-speed guiding operation of the band saw blade. The swing seat 4 is installed on the mounting support plate 3. The eccentricity makes the side surfaces of the guide wheel 8 and the guide wheel without edge 9 close to the side surfaces of the band saw blade to achieve natural guiding. When the guide wheel 8 and the guide wheel without edge 9 are worn, compensation can be achieved by adjusting the swing seat 4, which greatly extends the service life of the guide wheel 8 and the guide wheel without edge 9.
