Background technology
Sander is widely used in the polishing of machinery, the polishing of metope etc., but when sander is worked, can produce scrap, dust, not only can influence the quality of the product of polishing, and can produce pollution to environment, thereby influences the healthy of workman.For fear of the influence that dust brings, need in polishing, adopt dust catcher to carry out the dust suction operation usually, this just need add sends an individual's hands to carry out the operation of dust catcher, has greatly wasted human resources, has improved production cost.Also form product, but often all be to superpose simply, make that the volume of sander is big by dust catcher and sander are combined, Heavy Weight, the workman is very inconvenient when operation, influences operating efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide from dust suction shaft type sander, and volume is little, and is in light weight; Easy to use, can realize in the bruting process from dust suction, the dust of avoiding producing in the bruting process exerts an influence to product and human body; Increase work efficiency, reduce production costs.
For solving above-mentioned existing technical problem; The present invention adopts following scheme: from dust suction shaft type sander, comprise casing, be located at the casing afterbody handle, be located at the polishing dish of casing head, be provided with motor in the said casing; Said casing head is provided with the output shaft that is connected polishing dish central authorities; Said motor drives the polishing dish for the output shaft transferring power through driving snake and rotates, and said casing head also is provided with the disk of protection polishing dish, forms the cavity that is in communication with the outside between said disk and the polishing dish; The top of said disk is provided with the sweep-up pipe that is communicated with cavity; Be provided with the tube channel that is connected with sweep-up pipe in the said casing, be provided with the dust outlet tube that is connected with tube channel in the said handle, be provided with in the said dust outlet tube and be connected the dust suction fan blade that power is provided by it with motor.
As preferably, said driving snake through change-speed gearing to the output shaft transmission.Can regulate the transmission rotating speed effectively, simple in structure, transmission is effective.
As preferably, said polishing dish is provided with the suction port that is communicated with cavity.Be convenient to dust suction.
As preferably, be positioned at polishing dish sidepiece on the said disk and be provided with hairbrush.The dust that polishing is produced plays barrier effect, prevents that dust from scattering, and the dust around the mill of fighting each other simultaneously plays the cleaning effect.
As preferably, the top of said handle is provided with the power switch of control motor break-make, and the bottom of handle is provided with the speed governing knob of control motor speed.Thereby through the rotating speed of speed governing knob controlling motor speed control polishing dish and the power of dust suction, control is convenient.
As preferably, the rotor of said motor is provided with the motor cooling fan blade.Prevent motor overheating.
As preferably, said casing is provided with handle.Easy to use.
As preferably, said sweep-up pipe adopts flexible pipe, and said tube channel adopts the binary channels aluminum pipe.The pick-up performance of flexible pipe is good, and is convenient to the adjustment of position.
Beneficial effect:
The present invention adopts technique scheme to provide from dust suction shaft type sander, in sander, has combined dust exhaust apparatus effectively, and volume is little; In light weight; Easy to use, realized in the bruting process from dust suction, the dust of having avoided producing in the bruting process exerts an influence to product and human body; Improve operating efficiency, reduced production cost.
The specific embodiment
As shown in Figure 1; From dust suction shaft type sander, comprise casing 1, be located at casing 1 afterbody handle 2, be located at the polishing dish 3 of casing 1 head, be provided with motor 4 in the said casing 1; Said casing 1 head is provided with the output shaft 12 that is connected polishing dish 3 central authorities; Said motor 4 drives polishing dish 3 for output shaft 12 transferring power through driving snake 5 and rotates, and said casing 1 head also is provided with the disk 6 of protection polishing dish 3, forms the cavity 7 that is in communication with the outside between said disk 6 and the polishing dish 3; The top of said disk 6 is provided with the sweep-up pipe 8 that is communicated with cavity 7; Be provided with the tube channel 9 that is connected with sweep-up pipe 8 in the said casing 1, be provided with the dust outlet tube 10 that is connected with tube channel 9 in the said handle 2, be provided with in the said dust outlet tube 10 and be connected the dust suction fan blade 11 that power is provided by it with motor 4.Said driving snake 5 is through 13 pairs of output shaft 12 transmissions of change-speed gearing.Said polishing dish 3 is provided with the suction port 14 that is communicated with cavity 7.Being positioned at polishing on the said disk 6 coils 3 sidepieces and is provided with hairbrush 15.The top of said handle 2 is provided with the power switch 17 of control motor 4 break-makes, and the bottom of handle 2 is provided with the speed governing knob 16 of control motor 4 rotating speeds.The rotor of said motor 4 is provided with motor cooling fan blade 18.Said casing 1 is provided with handle 19.Said sweep-up pipe 8 adopts flexible pipe, and said tube channel 9 adopts the binary channels aluminum pipe.
During real work, turn on the power switch 17, starter motor 4 is through the rotating speed of speed governing knob 16 adjusting motors 4; Drive change-speed gearing 13 through driving snake 5 and give output shaft 12 transferring power, drive polishing dish 3 and rotate; When polishing dish 3 rotates; The dust suction fan blade 11 that motor 4 drives in the dust outlet tube 10 rotates; Dust is drawn onto in the cavity 7 through the space between suction port 14 and disk 6 and the polishing dish 3; Arrive in the dust outlet tube 10 with tube channel 9 through sweep-up pipe 8 successively again and discharge again, accomplish the dust suction operation, easy to use.Drive motor cooling fan blade 17 in the time of motor 4 work and rotate, prevented motor overheating effectively, avoided the motor overheating damage.
