Boxlike sander
Technical field
The present invention relates to a kind of grinding apparatus more particularly to a kind of boxlike sanders.
Background technique
Chain pearl is composed by multiple balls and across the tape of each ball centre bore, existing chain pearl type jewelry, jade,
The valuables such as noble metal ball are needed to carry out it surface polishing processing, further be conserved to it well, traditionally
Using manual grinding, more time and effort consuming.
Also occur some electric grinding equipment in the market, it is time saving and energy saving, the time is also saved, but current most machines are right
Chain pearl polish during, only in one direction or both forward and reverse directions drive chain pearl, either with which kind of direction rotation, due to not
Each ball rotation can be driven while driving chain pearl, therefore can only be polished the part of the surface of chain pearl, cause finally to polish
Effect is uneven, influences visual effect.
Summary of the invention
The object of the present invention is to provide a kind of boxlike sanders for capableing of adjust automatically polishing pressure.
Realizing the technical solution of the object of the invention is: a kind of boxlike sander, including being equipped with sliding chamber, positioning plate and baffle
Box body, scrubbing brush, adjusting bolt and the pressure spring being rotatably arranged on positioning plate;One end of pressure spring, which is connected to, to be adjusted on bolt, separately
One end is connected on scrubbing brush, and scrubbing brush is crimped on baffle;Scrubbing brush is slidably arranged in sliding chamber.
Present invention has the advantage that the size for workpiece of adaptively polishing, and apply adaptive polishing pressure to it.

Specific embodiment
(embodiment 1, boxlike sander)
The present embodiment is a kind of boxlike sander, and as shown in Fig. 1 to Fig. 2, which includes being equipped with sliding chamber 41, positioning
The box body 44 of plate 42 and baffle 43, the scrubbing brush 100 being slidably arranged in sliding chamber, the adjusting bolt being rotatably arranged on positioning plate
45 and pressure spring 46;One end of pressure spring, which is connected to, to be adjusted on bolt, and the other end is connected on scrubbing brush, and scrubbing brush is crimped on gear
On plate.Rotation adjusts bolt and the length that the adjusting bolt protrudes into sliding chamber is adjusted, so as to adjust the stress condition of pressure spring.
The present embodiment can adaptively polish the size of workpiece, and apply adaptive polishing pressure to it.
(embodiment 2, grinding device)
The present embodiment is a kind of chain pearl grinding device made of above-described embodiment 1, as shown in Fig. 3 to Fig. 7, including base 1,
Driving wheel 2, double end sander 3 and boxlike sander 4 on base roof are set, the active wheel drive of base inner is set
The combined support plate 5 on base side wall is arranged in mechanism, and the spinning roller 6 and spinning roller driving machine that are arranged on combined support plate
Structure 7.
Double end sander includes the shell 31 being fixed on base roof and two plates that shell opposite sides end is arranged in
Brush 100, shell are equipped with slot, and scrubbing brush 100 is plugged in slot.
Boxlike sander includes the box body 44 equipped with sliding chamber 41, positioning plate 42 and baffle 43, is slidably arranged in sliding chamber
Scrubbing brush 100, the adjusting bolt 45 and pressure spring 46 being rotatably arranged on positioning plate;One end of pressure spring, which is connected to, to be adjusted on bolt,
The other end is connected on scrubbing brush, and scrubbing brush is crimped on baffle.Boxlike sander is two, is located at double end sander
Two sides, the scrubbing brush setting in the scrubbing brush face double end sander of boxlike sander.Rotation adjusts bolt and the adjusting is adjusted
Bolt protrudes into the length of sliding chamber, so as to adjust the stress condition of pressure spring, and then adjusts scrubbing brush and the double end polishing of boxlike sander
Enclasping force between a corresponding scrubbing brush for device.
Combined support plate includes the mainboard 51, subplate 52 and lock-screw 53 being fixed on base side wall, on mainboard
Equipped with strip hole 54, subplate is equipped with and the screw hole of strip hole adaptation, lock-screw pass through strip hole and be tightened in screw hole, thus
Mainboard and subplate are fixedly linked.It is adjustable to be fixedly connected by changing the specific location of the be located at strip hole of lock-screw
The total length of mainboard and subplate afterwards.
The one end of end namely subplate far from base of subplate is arranged in spinning roller and spinning roller driving mechanism.Spinning roller includes ontology
61, ontology is equipped with ring-shaped groove 62 and protrudes from a plurality of spiral raised line 63 on ring-shaped groove wall body surface, each spiral raised line
Central axis relative to spinning roller is that the extending direction of oblique bending namely each spiral raised line and the rotation direction of spinning roller have
Inclination angle, so that each spiral raised line is to each ball one power for rotating the ball itself by ring-shaped groove.
In the present embodiment, driving wheel preferably uses rubber wheel, and frictional force is larger;Spinning roller ontology is made of nylon, spiral
Raised line is then made of rubber, and the rotation direction of driving wheel and spinning roller is opposite.This structure makes driving wheel have larger friction
Power is able to drive the rotation of chain pearl, and spinning roller then passes through backwards rotation, by spiral boss to one rotation of each ball in chain pearl
Power enables each ball while following driving wheel to rotate, and also has certain rotation when passing through spinning roller, thus again
When the secondary polishing by scrubbing brush clamping, not exactly the same surface when can be polished to last time by scrubbing brush polishing, to increase
The uniformity integrally polished promotes final grinding effect.
As shown in Figure 7, when the present embodiment is in use, by 8 sets of chain pearl on driving wheel and spinning roller, adjustment combined support plate is extremely
Suitable distance struts chain pearl, and driving wheel can be with positive and negative rotation, but spinning roller is always with the rotation direction of driving wheel on the contrary, driving wheel
After rotation, drives each ball to pass through two adjacent scrubbing brushes of clamping, polished using the bristle on scrubbing brush each ball;Separately
Outside, according to polishing demand and ball material, it is also possible to which cloth brush replaces the scrubbing brush in the present embodiment.
