Specific embodiment
Explanation that the utility model is further explained in the following with reference to the drawings and specific embodiments.
A kind of improved sand-blasting machine as shown in FIG. 1 to FIG. 3, including rack 1, rack 1 are made of two sidewalls and a pedestal
Upper end opening rectangular configuration, motor 2, the coaxially connected first rotating shaft of motor 2 are fixedly installed in the side wall of 1 left end of rack
3,3 other end of first rotating shaft is connected with the first guide sleeve 4, and threaded hole is offered in 4 two lateral walls of the first guide sleeve, and screw rod 5 passes through
Threaded hole protrudes into inside the first guide sleeve 4, and screw rod 5 is located at 4 inside one end of the first guide sleeve and is fixedly installed with clamping plate 6.Rack 1 is relatively electric
Driving cylinder 7 is installed, the piston rod 8 of driving cylinder 7 is connected with bull stick 9, and bull stick 9 is rotatably installed in by bearing on the right side of machine
Inside piston rod 8,9 other end of bull stick is equipped with the second guide sleeve 10, wherein the second guide sleeve 10 and 4 internal structure phase of the first guide sleeve
Together, and face is arranged, and is slidably mounted on the sliding rail 12 being arranged on the inside of 1 pedestal of rack by support rod 11 below the second guide sleeve 10
On；Piston rod 8 is driven to the left or to move right by driving cylinder 7, then the second guide sleeve 10 being connected with piston rod 8 is also to the left
Or move right, the distance between two guide sleeves are adjustable, the size of workpiece is adapted it to, then, then pass through the adjusting of screw rod 5 two
The distance between clamping plate 6 workpiece can be fixed clamping, suitable for the workpiece of various different size specifications, have a wide range of application
It is general；When sandblasting, drive first rotating shaft 3 to rotate by motor 2, then the first guide sleeve 4 connecting with first rotating shaft 3 also rotates with it,
And then the workpiece on the first guide sleeve 4 and the second guide sleeve 10 is driven to rotate, and 360 ° of sandblastings can be carried out to workpiece, sandblasting effect is good, and
Sandblasting is high-efficient.
It is also connected by key mode in first rotating shaft 3 and is connected with the first angular wheel 13, the first angular wheel 13 and second
Angular wheel 14 cooperates, and the number of teeth is 2 times of the number of teeth on the first angular wheel 13 on the second angular wheel 14, then when first
During one circle of the rotation of angular wheel 13, the second rotation half-turn of angular wheel 14, meanwhile, 14 top of the second angular wheel is logical
It crosses key connection mode and is also connected with the second shaft 15, in this way, the revolving speed that first rotating shaft 13 rotates should be the rotation of the second shaft 15
2 times of revolving speed.Second shaft 15 is connected with cam 16, and cam 16 is engaged with idler wheel 17, then the mistake rotated in first rotating shaft 3
Cheng Zhong, the first angular wheel 13 being keyed with first rotating shaft 3 also rotate, and drive the rotation of the second angular wheel 14, then and second
Angular wheel 14 drives the rotation of the second shaft 15, thus rotated with moving cam 16, during cam 16 rotates, sand blasting unit
It swings back and forth, sandblasting can be carried out to workpiece, be not necessarily to manual hand manipulation, saved manpower.
17 other end of idler wheel is fixedly connected with sand blasting unit, and the sand blasting unit other end is connected with spring 18, and spring 18 is fixed
It is mounted on 1 right side wall of rack, sand blasting unit is connected by feeding pipe 19 with feed inlet 20, and feed inlet 20 and sand reservoir box 21
It is connected.In the application, should preferably entire sand blasting unit cam 17 rotate during can coating workpieces.
Wherein, sand blasting unit includes sandblasting bracket 22, and sandblasting bracket 22 is fixedly connected with idler wheel 17, on sandblasting bracket 22 between
Every being evenly arranged with multiple openings 23,23 one end of opening are connected with nozzle 24, and the other end passes through feeding pipe 19 and feed inlet phase
Even, wherein feed inlet 20 is also connected by hose 25 with air compressor 26, and 25 position of hose is higher than feeding pipe 19,
Under the action of air compressor 26, can by the abrasive material in feeding pipe 19 by being sprayed in nozzle 24, by sandblasting bracket 22 come
Backhaul it is dynamic, to realize the sandblasting procedures to workpiece.
It is big due to workpiece to control the outflow of abrasive material wherein it is possible to switch valve is arranged on each feeding pipe 19
It is small inconsistent, by flowing out the nozzle quantity of abrasive material in the adjustable sandblasting bracket of switch valve, avoid the waste of abrasive material.
Meanwhile in the application, side is arranged in parallel with incomplete baffle A27 and not exclusively gear from top to bottom in opening 23
Plate B28, nozzle 24 are internally provided with incomplete baffle C29, wherein the incomplete baffle C29 and incomplete baffle B28 is mutual
In parallel, and positioned at the opposite side of incomplete baffle B28, preferably incomplete baffle A27 is 3/4 baffle, incomplete baffle B28
For 3/4 baffle, incomplete baffle C29 is 1/4 baffle.
In this way, in opening 23 only 1/4 part is made to pass through abrasive material, when the abrasive material entered by feed inlet 20 is more,
The channel kept off between incomplete baffle A27 and incomplete baffle B28 and opening can all be filled up by abrasive material, after entering nozzle,
There is lesser cross section since incomplete baffle C29 is opposite, at this point, relatively reducing the content of abrasive material mass flowing nozzle；When by
Feed inlet enter abrasive material it is less, cannot be fully filled with incomplete baffle A and incomplete baffle B and opening between channel when,
At this point, not exclusively baffle C is opposite to have biggish cross section, then the content of abrasive material mass flowing nozzle will not be too small；Can balance by
The abrasive content that nozzle sprays guarantees that sandblasting is uniform, improves sandblasting effect.
In addition, 16 short side of cam and idler wheel 17 are engaged when being engaged with long side and idler wheel 17, sandblasting bracket is pushed
The range difference of 22 movements is the half of distance between adjacent two opening 23 on sandblasting bracket 22, when first rotating shaft 3 drives workpiece to turn over
When turning 360 °, cam 16 has rotated 180 ° at this time, and the distance of 22 top nozzle 24 of sandblasting bracket movement is just between two openings
The half of distance, 24 position of nozzle are in the middle between two opening 23 of original, then when workpiece is not overturn, may not spray on workpiece
The part being coated onto can also be covered to after overturning, realize the comprehensive coating of workpiece.
It should be appreciated that although this specification is described in terms of embodiments, but not each embodiment only includes one
A independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should will say
As a whole, the technical solutions in the various embodiments may also be suitably combined for bright book, and forming those skilled in the art can be with
The other embodiments of understanding.
