Description

Technical Field

[0001] The present application belongs to the technical field of woodworking band saw machines, and in particular relates to a device for quickly installing a rubber ring of a woodworking saw wheel. Background Art

[0002] The band saw machine uses a ring-shaped endless band saw blade as a sawing tool, which is wound around two saw wheels to make a one-way continuous linear motion to saw wood. It is mainly composed of a bed, a saw wheel, an upper saw wheel lifting and tilting device, a band saw blade tensioning device, a saw blade guide device, a workbench, a guide plate, etc. The bed is made of cast iron or welded steel plates. Two saw wheels with the same diameter are installed on the upper and lower parts of the machine body respectively. The upper saw wheel can be adjusted up and down to facilitate loading and unloading of saw blades and adjusting the tension of saw blades. The lower saw wheel is the driving wheel, which is driven by a pulley. In order to reduce the wear and noise of the saw blade and saw wheel, a layer of belt is wrapped around the rim of the saw wheel.

[0003] If the press-fit and bonding between the pulley rubber ring and the wheel hub are not strong enough, the saw wheel will have a large moment of inertia and generate torsional vibration, and the rubber ring will slip and be damaged between the wheel hub and the pulley, thereby reducing the shock absorption effect and service life. The traditional method of pressing the pulley rubber ring is to hit the pulley with a heavy hammer. On the one hand, this traditional method is easy to hit the edge of the pulley and cause damage to the pulley; on the other hand, the striking point cannot be stabilized on the predetermined axis, making it difficult to install in place, resulting in uneven stretching of the rubber ring; on the other hand, manual operation is inefficient and relatively dangerous.

[0004] In order to improve the installation efficiency, a device for quickly installing the rubber ring of a woodworking saw wheel is urgently needed. Summary of the invention

[0005] The purpose of the present application is to provide a device for quickly installing the rubber ring of a woodworking saw wheel, in order to solve the problems of low efficiency, unsafety and easy damage to the rubber ring in the existing rubber ring installation method. The present application adopts a method of pressing the rubber ring between the wheel hub and the outer ring, so that the installation is achieved in place, and the whole process is fast and convenient, which greatly improves the pressing efficiency and enhances the pressing effect.

[0006] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows: A device for quickly installing a woodworking saw wheel rubber ring, which includes a tooling base, a mounting platform, a propping device and a pressing device.

[0007] Furthermore, a mounting rod is provided on the top of the saw wheel positioning shaft, and a bolt is threadedly connected to the top of the mounting rod.

[0008] Furthermore, the propping device includes a first propping block and a second propping block, wherein the first propping block and the second propping block are two blocks respectively and are symmetrically arranged to form a circular structure.

[0009] Furthermore, the two first support blocks are connected to the first cylinders via a pull rod, and the first cylinders are fixedly connected to the side plates.

[0010] Furthermore, the pressing device includes a push plate, a connecting plate and a connecting screw. The push plate is an annular ring that is sleeved outside the support device and fits with the support device. The upper end of the connecting screw is fixedly connected to the push plate, and the other end of the connecting screw passes through the top plate of the mounting platform and is connected to the connecting plate.

[0011] Furthermore, a cylinder connecting rod is fixedly connected to the center position of the connecting plate, and the cylinder connecting rod passes through the bottom plate of the mounting platform and is fixedly connected to a second cylinder.

[0012] Furthermore, the push plate is provided with a step higher than the surface of the push plate.

[0013] Furthermore, a linear bearing is provided between the connecting screw and the top plate, and the linear bearing and the connecting screw are slidably connected.

DETAILED DESCRIPTION

[0019] The technical solution of the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the scope of protection claimed in the present application is not limited to the scope described in the examples. Example 1

[0020] like Figure 1-7 As shown, the present application provides a device for quickly installing a woodworking saw wheel rubber ring, which includes a tooling base 1, a mounting table 2, a propping device 3 and a pressing device 5, wherein the mounting table 2 includes a bottom plate 16, a side plate 17 and a top plate 18, and is arranged above the tooling base 1; the propping device 3 and the pressing device 5 are both arranged on the mounting table 2; a saw wheel positioning shaft 4 is provided inside the propping device 3, and the saw wheel positioning shaft 4 and the mounting table 2 are fixedly connected. A mounting rod 20 is fixed to the top of the saw wheel positioning shaft 4, and a bolt 21 is threadedly connected to the top of the mounting rod 20. A clamping block 22 is provided between the bolt 21 and the mounting rod 20, and one end of the clamping block 22 is designed to be open. After the saw wheel 25 is placed into the mounting rod 20, the clamping block 22 is inserted between the saw wheel 25 and the bolt 21, so as to clamp the saw wheel 25 placed on the saw wheel positioning shaft 4 to prevent the saw wheel 25 from moving when the rubber ring 24 is hung; the pressing device 5 presses the rubber ring 24 on the opening device 3 between the hub and the outer ring of the saw wheel 25, thereby completing the installation of the saw wheel rubber ring, and the rubber ring 24 is pressed into the tooling to be installed in place, and the whole process is fast and convenient, which greatly improves the pressing efficiency and enhances the pressing effect.

[0021] The spreading device 3 includes a first support block 6 and a second support block 7. The first support block 6 is in the shape of two semicircular arcs, and the second support block 7 is in the shape of two T-shaped structures, and is fixedly mounted on the mounting platform. The first support block 6 and the second support block 7 are symmetrically arranged to form a circular structure. The height of the first support block 6 and the second support block 7 are consistent with the height of the saw wheel positioning shaft 4. When the saw wheel 25 is placed on the mounting rod 20, the outer ring of the saw wheel 25 is just above the first support block 6 and the second support block 7. The two first support blocks 6 are connected to the first cylinder 9 through the pull rod 8, and the first cylinder 9 is fixedly connected to the side plate 17. Under the action of the first cylinder 9, the pull rod 8 can be stretched or compressed. When the pull rod 8 is stretched, the first support block 6 and the second support block 7 are close to each other to the closest position. At this time, the undeformed rubber ring 24 is placed on the first support block 6 and the second support block 7. When the pull rod 8 is compressed, the first support block 6 is away from the second support block 7, so that the rubber ring 24 on the first support block 6 and the second support block 7 is tensioned. In this way, the stretching force of the rubber ring 24 is uniform.

[0022] The pressing device 5 includes a push plate 10, a connecting plate 12 and a connecting screw 11. The push plate 10 is annular and sleeved outside the opening device and fits with the opening device. The upper end of the connecting screw 11 is fixedly connected to the push plate 10, and the other end of the connecting screw 11 passes through the top plate 18 of the mounting table and is connected to the connecting plate 12. There are multiple connecting screws 11, specifically four in this embodiment; the center position of the connecting plate 12 is fixedly connected to a cylinder connecting rod 13, and the cylinder connecting rod 13 passes through the bottom plate 16 of the mounting table and is fixedly connected to a second cylinder 14. The connecting plate 12 is driven to move upward by the action of the second cylinder 14 and the connecting plate 12, and the connecting plate 12 drives the push plate 10 to move upward through the connecting screw 11, and the push plate 10 pushes the rubber ring 24 sleeved on the opening device 3 upward, so that the rubber ring 24 is pressed onto the saw wheel 25.

[0023] Specifically, the upper surface of the push plate 10 is provided with a step 15 higher than the surface of the push plate 10, and the rubber ring 24 on the opening device 3 is pushed and pressed onto the saw wheel 25 through the step 15. Because the step 15 is convex and relatively high, the connecting screw 11 of the outer ring of the push plate 10 can be prevented from interfering with the rubber ring 24 when the rubber ring 24 is pushed upward.

[0024] In addition, a linear bearing 19 is provided between the connecting screw 11 and the top plate 18, and the linear bearing 19 is slidably connected to the connecting screw 11. After the second cylinder 14 is started, the connecting screw 11 can slide upward inside the linear bearing 19.

[0025] Specific operation process: In the initial state, the pull rod 8 is in a stretched state, the first support block 6 and the second support block 7 are close to each other to form a circular ring shape, and the undeformed rubber ring 24 is put on the first support block 6 and the second support block 7 at this time.

[0026] The first air cylinder 9 is started to compress the pull rod 8, and under the action of the pull rod 8, the first support block 6 is pulled to both sides away from the second support block 7, so that the rubber ring 24 is tensioned.

[0027] The saw wheel 25 is mounted on the mounting rod 20 and a pressing block 22 is placed thereon for fixing.

[0028] Start the second cylinder 14, so that the connecting plate 12 on it moves upward under the action of the cylinder connecting rod 13, thereby making the push plate 10 at the other end of the connecting screw 11 move upward, and the step 15 on the push plate 10 pushes the rubber ring 24 upward onto the saw wheel 25 to complete the installation.

[0029] This push-in method enables the rubber ring 24 to be accurately installed in place, and the entire process is fast and convenient, which greatly improves the press-in efficiency and enhances the press-in effect.

[0030] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
