Abstract

The utility model provides a vertical sample grinding machine, which belongs to a metallic grinding device and is mainly used for grinding various metallic samples. The utility model is characterized in that a tubular core axle 10 is fixedly arranged between the upper part of a machine body 1 and the lower part of the machine body 1, the core axle 10 is positioned in a hole on one end of a rocker arm 4 which can be slid along an axial direction and rotated on the core axle 10, and the rocker arm 4 is fixedly connected with a lifting slide block 13 which is positioned in the core axle 10. The lifting slide block 13 is connected by screw threads with a leading screw 9 which is axially connected with the machine body 1 and arranged in the core axle 10. The other end of the rocker arm 4 is provided with a motor 3 which is connected with a grinding wheel 6. The machine body 1 on the lower part of the grinding wheel 6 is provided with a clamp 7.

Description

Vertical machine for grinding

The utility model relates to a kind of equipment for grinding, especially a kind of vertical sample grinding machine.The main various test buttons of grinding, so as on the direct reading spectrometry instrument assay determination metal composition.

Existing grind away equipment is to be fixed with motor on frame, and drives discoid and horizontally disposed emery wheel by transmission device, adopts the manual sample grinding method during grinding sample.Owing to there are not anchor clamps, can only be the hand-held sample grinding on emery wheel of operator, emery wheel and test button rub and produce high temperature, and emery wheel high speed rotary manipulation person is difficult to bear in addition, and the phenomenon that often occurs slipping out of the hand causes sample to fly in circles, and has unsafe factor.Promptly lose time with existing equipment grinding sample, make operator's spirit be in the high-pressure state all the time again.The grinding dynamics is little and inhomogeneous, causes the specimen surface out-of-flatness, directly influences direct reading spectrometry result's levels of precision, can not instruct produced on-site quickly and accurately.Also need pass through sand paper (cloth) polishing because grinding finishes again, therefore increase grind away time and cost again.

The purpose of this utility model provides that a kind of easy to operate, grind away speed is fast, the vertical sample grinding machine of good grinding quality.

Technical solution of the present utility model is: a kind of vertical sample grinding machine, it is characterized in that: be provided with body 1, fixedly be connected to the mandrel 10 of tubular between the top of body 1 and the bottom, mandrel 10 is located in the hole of an end of the Rocker arm 4 that can endwisely slip and rotate on the mandrel 10; Rocker arm 4 is affixed with the lifting slider 13 that is positioned at mandrel 10; in lifting slider 13 and the mandrel 10 and leading screw 9 thread connection body 1 axial restraint; the other end of Rocker arm 4 is connected to motor 3; motor 3 and emery wheel 6 join, and on the body 1 of emery wheel 6 belows anchor clamps 7 are housed.

The bottom of described body 1 is provided with groove 8.

Described leading screw 9 upper ends are connected to handwheel 2.

Described Rocker arm 4 also is connected to handle 5.

Described emery wheel 6 is bowl-shape emery wheel.

The described mandrel 10 outer dirt-proof boots 14 that are with.

Also be provided with on the described leading screw 9 and adjust nut 11.

The utility model compared with prior art has following advantage: because this device has anchor clamps, sample is firm during grinding, and the unlikely sample that occurs takes off and flies phenomenon, and is safe and reliable.Because rocking arm can be along mandrel rotation and lifting by leading screw, grinding great efforts and evenly, stock removal also can arbitrarily be controlled, the grinding time lacks, and efficient height, quality are good.

Fig. 1 is the front view of the utility model embodiment;

Fig. 2 is a right view shown in Figure 1;

Fig. 3 is an I portion cutaway view Amplified image shown in Figure 1;

Fig. 4 is that cutaway view is looked on a left side shown in Figure 3.

Below in conjunction with drawings and Examples the utility model is described further:

As shown in Figure 1, 2: 1 is Contraband shape body, adopts channel-section steel to be welded, but also casting.Shown in Fig. 3,4: the material of cylindric mandrel is the A3 steel, the upper end connects with the upper bolt of body 1, the lower end connects with the lower bolt of body 1, leading screw 9 places in the mandrel 10, the top of leading screw 9 connects with the upper bearing of body 1, to guarantee the rotation and the axial restraint of screw mandrel 9, the handwheel 2 with leading screw 9 key connecting is equipped with in the upper end of leading screw 9.As shown in Figure 4: a side of mandrel 10 has vertical slotted hole 12, lifting slider 13 is positioned at mandrel 10, and with leading screw 9 thread connection; an end of Rocker arm 4 is enclosed within outside the mandrel 10; can radially rotate and endwisely slip along mandrel 10, Rocker arm 4 be fixedly connected at slotted hole 12 places and lifting slider 13 by bolt, adjusts nut 11 and leading screw 9 thread connection; and be positioned at the top of lifting slider 13, to adjust the height that limits Rocker arm 4.As shown in Figure 1: the other end Bolt Connection of Rocker arm 4 has the axle of vertical machine 3, motor 3 upward fixedly to be connected to bowl-shape emery wheel 6, on the below body 1 of bowl-shape emery wheel 6 anchor clamps 7 are housed, anchor clamps 7 can be machine with pincers, also can be electromagnetism or Permanent magnet plate, can also be three-jaw or chuck.The lower screw of body 1 is fixed with the groove 8 that surrounds with the A3 plate, and the metal fillings under preventing to grind flies upward.Handle 5 and Rocker arm 4 termination bolting or welding.The material of Rocker arm 4, lifting slider 13, adjustment nut 11, leading screw 9 is the A3 steel.Be with respectively with rubber outside the mandrel up and down 10 of Rocker arm 4 is that the bellows of material is as dirt-proof boot 14.Prevent that dust from entering.

Its course of work is: sample that will grinding is contained on the anchor clamps 7 and clamps, connect motor 3, make bowl-shape emery wheel 6 rotations, rotate handwheel 2, leading screw 9 can rotate thereupon, moves up and down along mandrel 10 thereby lifting slider 13 can drive Rocker arm 4, make emery wheel 6 contacts or leave sample, move handle 5, Rocker arm 4 is rotated along mandrel 10, be ground to the whole regeneration surface of sample with the edge that guarantees bowl-shape emery wheel 6.
