Description

Technical Field

[0001] The utility model relates to the technical field of panel saws, and more specifically, to a saw blade replacement rack for a panel saw. Background Art

[0002] The main use of a panel saw is to saw large-format boards (base materials) into various board pieces that meet certain dimensional specifications and accuracy requirements. The surfaces of these large-format base materials can be either uncoated or already coated. Usually, the sized board pieces sawn by a panel saw have accurate dimensions and smooth sawing surfaces, and can enter subsequent processes (such as edge banding, etc.) without further fine processing.

[0003] The woodworking panel saw with a movable workbench is widely used. It can be used not only for longitudinal, transverse or angled sawing of hard and soft solid woods, plywood, fiberboard, particleboard, and veneer panels with thin wood, paper, plastic, non-ferrous metal or waxed lacquer on one or both sides to obtain board pieces that meet the specified dimensions; at the same time, it can also be used for cutting various plastic boards, insulating boards, thin aluminum plates and aluminum profiles, etc. Some machine tools are also equipped with milling devices and can perform processing such as grooves and rabbets within a width of 30 - 50 mm. During processing, the workpiece is placed on the manually pushed workbench to make the workpiece achieve a feeding movement, which is very convenient.

[0004] Currently, when replacing the saw blade of a panel saw, a worker needs to hold an adjustable wrench in one hand to clamp the nut of the panel saw, and insert a hexagonal wrench into the hexagonal limit slot on the saw shaft with the other hand and rotate it counterclockwise. The adjustable wrench plays a role in restricting the rotation of the saw shaft. Since the opening size of the adjustable wrench needs to be manually adjusted, it is relatively cumbersome to use and consumes manpower. Content of the Utility Model

[0005] The utility model provides a saw blade replacement rack for a panel saw, which can save manpower and facilitate the replacement of the saw blade.

[0006] A saw blade replacement rack for a panel saw includes a bottom plate. The fixed end of a height adjustment assembly is fixedly connected to the bottom plate. The movable end of the height adjustment assembly is connected to a hollow column. A clamping mechanism is arranged inside the hollow column. A driving motor is also fixedly arranged inside the hollow column. The output shaft of the driving motor penetrates the hollow column and is fixedly connected to a positioning block at the end.

[0007] The clamping mechanism includes a plurality of clamping plates. One end of each clamping plate is fixedly connected to one end of a guiding column. The other end of each guiding column penetrates the hollow column and is fixedly connected to one end of a slider. Each slider is slidably arranged in a corresponding sliding groove. The sliding grooves are evenly opened on a disc. One side of the disc is fixedly connected to the hollow column.

[0008] One end of an L-shaped rod is rotatably connected to each of the sliders, and the other ends of the L-shaped rods are rotatably connected to an eccentric position of a turntable. The turntable is rotatably connected to the central axis of the disc.

[0009] There are 4 sliders, and the adjacent chutes form a 90-degree angle. One end of the housing of an electric push rod is fixedly connected to one of the sliders, and the telescopic rod of the electric push rod is fixedly connected to another slider.

[0010] The height adjustment assembly includes a support rod, a sliding rod is slidably connected to the support rod, and a setscrew is provided on the support rod.

[0011] As a further limitation of this technical solution, a clamping block is fixedly connected to the other end of the clamping plate.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are:

[0013] By adjusting the height of the clamping mechanism, loosen the setscrew, slide the sliding rod in the support rod, and after adjusting to a suitable position, tighten the setscrew to lock the height.

[0014] The telescopic rod of the electric push rod extends, driving two of the sliders to move. The sliders move in the chutes, driving the corresponding two L-shaped rods to swing. The L-shaped rods drive the turntable to rotate on the disc, driving the other two L-shaped rods and the sliders to move. The 4 sliders move in the corresponding chutes towards the direction close to the axis of the disc, getting closer to each other. The sliders drive the clamping plate and the clamping block to move, clamping the nut on the push saw. The driving motor is started, and the output shaft of the driving motor rotates counterclockwise. Since the nut has been clamped at this time, the saw blade will not rotate accordingly, enabling the saw blade to be smoothly removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following further describes the present utility model in conjunction with the appended Figures 1-4 drawings and embodiments.

[0022] The present utility model provides a saw blade replacement rack for a push table saw, including a bottom plate 7. The fixed end of the height adjustment assembly is fixedly connected to the bottom plate 7. The movable end of the height adjustment assembly is connected to a hollow column 2. A clamping mechanism is arranged inside the hollow column 2. A driving motor is also fixedly arranged inside the hollow column 2. The output shaft of the driving motor passes through the hollow column 2 and is fixedly connected to a positioning block 9 at the end.

[0023] The clamping mechanism includes a plurality of clamping plates 1. One end of each clamping plate 1 is fixedly connected to one end of a guide post 3. The other end of each guide post 3 passes through the hollow column 2 and is fixedly connected to one end of a slide block 10. Each slide block 10 is slidably arranged in a corresponding chute 14. The chutes 14 are evenly arranged on a disc 15. One side of the disc 15 is fixedly connected to the hollow column 2.

[0024] One end of an L-shaped rod 11 is rotatably connected to each slide block 10. The other end of the L-shaped rod 11 is rotatably connected to an eccentric position of a turntable 12. The turntable 12 is rotatably connected to the central axis of the disc 15. The turntable 12 is a square turntable. The top end of each is hinged to the L-shaped rod 11. The included angle between the two sides of the L-shaped rod 11 is 90 degrees.

[0025] There are 4 slide blocks 10. The adjacent chutes 14 form a 90-degree angle. One end of the housing of an electric push rod 13 is fixedly connected to one of the slide blocks 10, and the telescopic rod of the electric push rod 13 is fixedly connected to another slide block 10.
