Wherein, the workbench bottom is provided with the connector of band deep-slotted chip breaker, and connector is by being bolted on the case lid.

Wherein, the deep-slotted chip breaker of described connector has angle index.

Beneficial effect: (1) the utility model adopts the Worm-gear type transmission device, and main shaft speed change is reasonable, and main shaft can drive the lifting repeatedly of polishing rod in bruting process, polishing precision height, and size Control puts in place.(2) workbench can adjusting angle, is convenient to have the workpiece polishing of angle, satisfies different practical requirements.(3) Mechanized Processing has improved production efficiency greatly, has saved manpower, has filled up the industry blank.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the dextrad enlarged diagram at A place among Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further explanation.

As shown in Figure 1, carpenter's internal grinder of the present utility model comprises case lid 1, workbench 2, motor 3, main shaft 4, rack sleeve 5, polishing rod 6, adapter sleeve 7, worm gear 8, slide plate 9, the axis of guide 10 and connecting rod 11, the case lid 1 of casing is provided with workbench 2, bottom half is provided with the electric machine support of fixed electrical machinery 3, one end of main shaft 4 passes the rack sleeve 5 that is installed on the case lid 1 and is connected with polishing rod 6, polishing rod 6 one ends are cylinder, and the middle part is the changeover portion that has cone, and the other end is a thread segment.The barrel portion of polishing rod 6 passes from the through hole of workbench 2, and changeover portion and thread segment insert in the installing hole of main shaft 4, and it is fixing to be threaded with it.The other end of main shaft 4 is connected by key with the adapter sleeve 7 that is installed in bottom half, and main shaft 4 can slide up and down in adapter sleeve.The opposite side of adapter sleeve 7 is connected with the turning cylinder of the motor 3 that passes the electric machine support through hole; Main shaft 4 middle parts are provided with one section worm screw, worm screw and worm gear 8 engagements that are installed on the worm gear axle bed, and the worm gear axle bed is fixedly mounted on the slide plate 9, and slide plate 9 is fixed on the rack sleeve 5, is provided with through hole on slide plate 9, and the axis of guide 10 passes and is fixed on the case lid 1 from through hole.Worm gear 8 mandrels one end face departs from 2cm place, center and flexibly connects a

connecting rod

11, and 11 the other end of connecting rod is fixed on the inwall of case lid 1, also can a connecting rod be installed respectively on the both sides end face of worm gear 8 mandrels, can make operation more steady.

Initial power comes from motor 3 and rotates, the hypothesis motor speed is 1400 rev/mins in the utility model, motor shaft links to each other with adapter sleeve 7, adapter sleeve 7 drives main shaft 4 and rotates, main shaft 4 can slide up and down in adapter sleeve 7, and the worm screw that is contained in main shaft 4 middle parts is rotated with main shaft 4, and worm engaging worm gear 8 rotates together, suppose that worm gear 8 and the gearratio of worm screw are 1: 25, this moment, worm gear 8 rotating speeds were 56 rev/mins.Connecting rod 11 is along with worm gear 8 rotates, because connecting rod 11 and case lid 1 link fixed-site, whole worm gear axle bed, worm gear 8 and slide plate 9 all carry out reciprocal elevating movement thereupon regularly, and rack sleeve 5 is movement therewith also, 10 balances of the axis of guide and guide effect guarantee that slide plate 9 can moving linearly.Rack sleeve 5 drives

main shaft

4, and 6 rotations of the polishing that links to each other with main shaft 4 rod, and excellent 6 rotating speeds of polishing this moment are 1400 rev/mins, makes reciprocal lifting fortune merit (56 times/minute, stroke 4cm) simultaneously.

As shown in Figure 2, the bottom of workbench 2 is fixed with the connector 12 that has deep-slotted chip breaker, and connector 12 is by being bolted on the case lid 1, and the deep-slotted chip breaker of described connector 12 has angle index.The workbench 2 that is located at case lid 1 top can promptly be made both forward and reverse directions 0 to 45 degree and adjust along with the capable groove slippage of the arc that indicates scale.After treating that the grinder part is placed on the level table of workbench 2, if when treating that there is angle in the axle center of rounding arcwall face with polishing rod 6, unclamp bolt, workbench 2 rotated in the capable groove of arc, be adjusted to the axle center for the treatment of the rounding arcwall face and polishing rod 6 fastening bolt when parallel, begin polishing then.

The invention provides a kind of thinking and method of carpenter's internal grinder; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications; as perfect in addition, also can be used for plastics, rubber, nylon products industry, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
