Description

Technical Field

[0001] The utility model belongs to the technical field of electric tools, relates to an improvement in the installation structure of a motor, and in particular to a suspension fixing device for a table saw cutting motor. Background Art

[0002] As a common electric tool for processing wood and profiles, table saws are widely used in the construction, mechanical processing, furniture production, and decoration industries. The structure of a table saw is mainly composed of a box, a saw blade, a power system, and a workbench for placing materials. The workbench is installed on the top of the box, and the power system is installed in the box. The material is cut by driving the saw blade to rotate. The power system is generally powered by an electric motor, which is also called a main motor or a cutting motor.

[0003] Most existing table saws use a method of connecting and fixing the cutting motor to the workbench, that is, the cutting motor is suspended and fixed under the workbench through a connecting assembly. However, during cutting, the workbench will be disturbed by the vibration generated by the cutting motor and the saw blade, which will affect the cutting accuracy and also generate noise. In addition, the housing used in table saws with dust removal function is mostly made of metal materials, and the lower part of the housing is generally used as a sealed dust collection area. In order to allow dust to be collected in the dust bag, the air flow is discharged to the outside during dust removal, so negative pressure is generated in the dust collection area. If the partition above the dust collection area is not strong enough, for example, plastic parts are used, the partition will be deformed downward, affecting the safety and working performance of the table saw.

[0004] For example, the "dust-free table saw with a dust suction mechanism" disclosed in the Chinese patent (authorization publication number CN212948226U) includes: a mounting bracket and an electric saw mounted on the mounting bracket, the electric saw includes a motor and a saw blade, the mounting bracket is hinged with a dust cover, and the dust cover is placed above the saw blade; a dust box is provided on one side of the mounting bracket, the lower end of the saw blade is placed in the dust box, the motor is provided with a dust suction mechanism, the dust suction mechanism includes a dust suction pipe, a dust collecting bag and a dust suction fan arranged in the motor, one end of the dust suction pipe is connected to the dust box through the motor housing, and the other end of the dust suction pipe is connected to the dust collecting bag.

[0005] The above table saw still has the problem of unstable installation of the cutting motor, which easily causes the workbench to vibrate, thereby reducing the accuracy of material cutting. Utility Model Content

[0006] The utility model aims to provide a cutting motor suspension fixing device for a table saw, which is used to solve the problems existing in the cutting motor installation structure of the existing table saw.

[0007] In order to achieve the purpose of this utility model, the following technical solutions are adopted:

[0008] Table saw cutting motor suspension fixing device, including a box body, a workbench and a cutting motor. The cutting motor is arranged in the box body, the workbench is installed on the top of the box body. A vertical slot is arranged in the box body, and the slot is used to cooperate with the side of the front end cover of the cutting motor. A fixing seat connected to the box body is arranged on the side of the slot. A positioning structure is arranged on the front end cover of the cutting motor, and the positioning structure and the fixing seat are cooperated through a first connecting piece to fix the cutting motor in the box body. The first connecting piece and the workbench are cooperated through a second connecting piece to suspend the cutting motor below the workbench.

[0009] In order to further achieve the purpose of the present utility model, the following technical solutions can also be adopted:

[0010] For the table saw cutting motor suspension fixing device as described above, the first connecting piece is a bolt and a fixing nut. The fixing nut is sleeved in the middle of the bolt. The positioning structure is a card slot or a fixing ring with a through hole in the middle. The upper part of the bolt passes through the through hole of the positioning structure.

[0011] For the table saw cutting motor suspension fixing device as described above, a heat insulation gasket is installed between the fixing nut and the positioning structure, and the heat insulation gasket is sleeved on the bolt above the fixing nut.

[0012] For the table saw cutting motor suspension fixing device as described above, the second connecting piece is a suspension nut and a screw. A suspension through hole is opened on the workbench. The lower end of the suspension nut is fixed to the upper part of the first connecting piece, and the screw passes through the suspension through hole and is connected and fixed to the suspension nut.

[0013] For the table saw cutting motor suspension fixing device as described above, an intermediate partition is arranged in the box body, and the slot and the fixing seat are installed above the intermediate partition.

[0014] For the table saw cutting motor suspension fixing device as described above, two sets of the fixing seats and the positioning structures are symmetrically arranged respectively with the axis of the rotating shaft of the cutting motor as the axis.

[0015] For the table saw cutting motor suspension fixing device as described above, a connecting plate is installed at the rear end of the cutting motor, and the connecting plate fixes the cutting motor and the box body through connecting screws.

[0016] For the table saw cutting motor suspension fixing device as described above, the box body is a plastic part formed by integral injection molding.

[0017] The advantages of the present utility model are as follows:

[0018] Compared with the structure in which the cutting motor in the existing table saw is hoisted below the workbench, the cutting motor of the present utility model adopts a fixing structure combining fixing with the partition and hoisting with the workbench. Thus, it can better reduce the vibration of the workbench and the noise during work, and improve the cutting environment and cutting effect.

[0019] In particular, when the box body and the middle partition are plastic parts integrally injection-molded, the cutting motor mounting structure of the present utility model can simultaneously provide an upward pulling force to the partition to prevent the partition from deforming downward due to the negative pressure in the dust collection area, thereby improving the overall safety and working progress of the table saw.

The lower end is threadedly connected to the threaded hole opened on the fixing seat 6, and then the fixing nut 9 is screwed in and cooperates with the positioning structure 7 to fix the cutting motor 3 in the box body 1.

[0030] In addition, a heat insulation gasket 10 is installed between the fixing nut 9 and the positioning structure 7. The heat insulation gasket 10 is sleeved on the bolt 8 above the fixing nut 9 to cut off the heat transfer from the cutting motor 3 to the box body 1.

[0031] Continue to refer to Figure 1 As shown, the second connecting piece in this embodiment is a hanging nut 11 and a screw 12. A hanging through hole is opened on the workbench 2. The lower end of the hanging nut 11 is fixed to the upper part of the first connecting piece, and the screw 12 passes through the hanging through hole and is connected and fixed to the hanging nut 11. The hanging nut 11 is a long nut. The lower part of the hanging nut 11 is threadedly connected to the upper part of the bolt 8 of the first connecting piece, so that it can be used as the mounting seat of the screw 12. After placing the workbench 2, it is connected with the screw 12 and the long nut to further increase the connection strength.

[0032] In order to facilitate the fixation of the cutting motor 3 and the setting of the fixing seat 6. In this embodiment, an intermediate partition 13 is arranged in the box body 1, and the slot 4 and the fixing seat 6 are installed above the intermediate partition 13.
