Description

Technical Field

[0001] The utility model relates to the technical field of floor saws, in particular to a saw blade disassembly and assembly device for a floor saw. Background Art

[0002] Floor saws are cutting tools for cutting wooden floors, plastic boards and soft materials. They are easy to use and safe, so they have been widely used. However, such cutting saws will inevitably produce a lot of sawdust and other dust when used, which has a certain impact on the health of workers and also causes great pollution to the surrounding environment.

[0003] During the use of the floor saw, a saw blade disassembly and assembly device of the floor saw is required. The existing floor saw blades are used in a variety of scenarios, and different working environments have different requirements for the function of the floor saw blades, resulting in an increase in the number of replacements of the floor saw blades, delaying the overall working progress of the equipment. The current floor saws use a screwdriver to tighten the screws or a wrench to tighten the bolts for the saw blade disassembly and assembly problem. In order to prevent the saw blade from falling off and causing safety hazards, several layers of bolts are often tightened. Therefore, other tools must be always available when the saw blade needs to be replaced. This disassembly and assembly method is time-consuming and labor-intensive, which seriously affects the use efficiency of the floor saw blade and cannot meet the use needs. Therefore, a saw blade disassembly and assembly device for a floor saw is proposed to solve the above-mentioned problems. Utility Model Content

Therefore, other tools must be always available when the saw blade needs to be replaced. This disassembly and assembly method is time-consuming and labor-intensive, which seriously affects the use efficiency of the floor saw blade and cannot meet the use needs.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 In the present embodiment, a saw blade disassembly and assembly device for a floor saw comprises a saw blade body 1, a fixing seat 2 fixedly connected to the bottom of the saw blade body 1, and an installation box 3 arranged at the bottom of the fixing seat 2, the interior of the installation box 3 is provided with a fixing mechanism 4 extending to the outside thereof, the outside of the installation box 3 is provided with an anti-falling component 5, the fixing mechanism 4 comprises a motor 41 fixedly installed on the outside of the installation box 3, a bidirectional screw 42 extending to the inside of the installation box 3 is fixedly connected to the output shaft of the motor 41, a threaded block 43 is threadedly connected to the left and right sides of the outside of the bidirectional screw 42, the tops of the two threaded blocks 43 are fixedly connected to connecting rods 44 extending to the outside of the installation box 3, the ends of the two connecting rods 44 away from the threaded block 43 are fixedly connected to clamps 45, and the opposite sides of the two clamps 45 are fixedly connected to blocks 46 extending to the inside of the fixing seat 2.

[0023] The motor 41 is started by the controller to drive the bidirectional screw 42 to rotate. The rotation of the bidirectional screw 42 drives the two threaded blocks 43, the two connecting rods 44 and the two clamps 45 to move closer or apart, so that the clamping block 46 extends to the inside of the clamping slot, thereby disassembling and assembling the fixed seat 2 and the saw blade body 1, achieving the advantage of easy disassembly and assembly.

[0024] The bidirectional screw rod 42 is rotatably connected to the inside of the installation box 3 , and the two threaded blocks 43 are symmetrically distributed on the outside of the bidirectional screw rod 42 .

[0025] Specifically, a sliding opening adapted to the connecting rod 44 is provided inside the installation box 3, and the outer diameter of the connecting rod 44 is adapted to the inner diameter of the sliding opening. A card slot adapted to the card block 46 is provided inside the fixing seat 2, and the card block 46 is card-connected with the card slot.

[0026] It should be noted that a slider 47 is fixedly connected to the bottom of the threaded block 43, and a slide rail 48 adapted to the slider 47 is fixedly installed on the inner bottom wall of the installation box 3, and the slider 47 is slidably connected to the slide rail 48. By providing the slider 47 and the slide rail, the stability of the threaded block 43 driving the clamping block 46 to move left and right is improved.

[0027] In this embodiment, the anti-falling component 5 includes a fixing block 51 fixedly connected to the bottom of the fixing seat 2 and a mounting seat 52 fixedly connected to the top of the mounting box 3. The left and right sides of the outside of the fixing block 51 are fixedly connected with connecting plates 53. The side of the connecting plate 53 away from the fixing block 51 is fixedly connected with two springs 54. The ends of the two springs 54 away from the connecting plate 53 are fixedly connected with abutment blocks 55. The springs 54 are deformed by pressing the abutment blocks 55, and then the fixing block 51 is inserted into the interior of the mounting seat 52. The reaction force of the springs 54 causes the abutment blocks 55 to be stuck into the interior of the moving port, thereby stably connecting the fixing seat 2 and the mounting box 3, preventing the fixing seat 2 from falling off from the saw blade body 1, and achieving the advantage of strong practicality.

[0028] The four springs 54 are distributed in a rectangular shape outside the fixing block 51 , and the fixing block 51 is a solid cuboid.

[0030] The working principle of the above embodiment is:

[0031] When in use, the motor 41 is started by the controller to drive the bidirectional screw 42 to rotate. The rotation of the bidirectional screw 42 drives the two threaded blocks 43, the two connecting rods 44 and the two clamps 45 to move closer or apart, so that the clamping block 46 extends to the inside of the clamping slot, thereby disassembling and assembling the fixed seat 2 and the saw blade body 1, and the abutment block 55 is pressed to deform the spring 54, and then the fixed block 51 is inserted into the inside of the mounting seat 52. The reaction force of the spring 54 makes the abutment block 55 stuck in the inside of the moving port, thereby stably connecting the fixed seat 2 and the mounting box 3 to prevent the fixed seat 2 and the saw blade body 1 from falling off.
