Technical field

The utility model relates to milling apparatus, more specifically, it relates to a kind of ball mill.

Background technique

Since Ceramic Balls have the remarkable advantages such as density, high mechanical strength, wear-resisting property is good, as wear-resistant parts It is widely used in the fluid spool of the carriages such as bearing, ball nut or control high-pressure fluid, realizes long-term stable operation, Reduce the function of maintenance cost.

A kind of bearing is disclosed in the Chinese patent that notification number is CN202097654U and precision machinery Ceramic Balls add Tooling is set, including bracket, a float plate, and installation on the bracket, and can move up and down on it；One power generating device, it is right The float plate generates a power straight up；One lower millstone, is mounted in float plate, and by the driving of the first variable-frequency motor in Mandrel Y2 rotation；One upper millstone is fixed on the top of the lower millstone, and is revolved by the driving of the second variable-frequency motor around central axis Y1 Turn, the direction of rotation of the upper millstone and the lower millstone is on the contrary, e at a distance between central axis Y2 and central axis Y1.

But not set corresponding connection component between above-mentioned upper millstone and body, cause in upper millstone towards in direction When body is mobile, upper millstone is easy to happen shaking, so that lower millstone is deviated, at this time, it may be necessary to which staff's manual-alignment, not only drops Low working efficiency, has also aggravated the pressure of staff.

Utility model content

In view of the deficienciess of the prior art, improving work effect the purpose of this utility model is to provide a kind of ball mill Rate and the pressure for alleviating staff.

To achieve the above object, the utility model provides following technical solution:

A kind of ball mill, including body, are provided with the upper millstone and lower millstone of coaxial line on body, the lower millstone only company of rotation It is connected on body, the actuator for driving lower millstone to rotate is provided on body, upper millstone is located above lower millstone, on body It is provided with the lifting assembly for driving upper millstone only to move along its axis direction, several and upper millstone axis is fixed on body Parallel support rod, body be additionally provided with the one-to-one link block of support rod, one end of link block and upper millstone are detachable Connection, the other end offer and the clamping groove of corresponding support rod cooperation clamping.

By adopting the above technical scheme, the clamping groove of link block and support rod are clamped, link block is then installed on upper mill On disk, so that upper millstone is moved along its axis towards lower millstone, in the work of link block and support rod under the action of lifting group valence Under, the shaking of upper millstone is reduced, makes upper millstone and lower millstone rapid alignment, to improve work efficiency and mitigate work people The pressure of member.

Further, the inner wall of clamping groove is fixed with slipping block, offered on support rod along its length setting and with The strip grooves of slipping block cooperation clamping.

By adopting the above technical scheme, mill is improved to realize dual clamping by setting strip grooves and slipping block The stability of disk.

Further, the limited block being fixed in strip grooves below link block, limited block are provided with towards link block Guide surface, and guide surface extends downwardly, and when slipping block is connected to guide surface, upper millstone is abutted with lower millstone.

By adopting the above technical scheme, when slipping block and limited block abut, long mill is abutted with lower millstone, to realize limit Position；Limited block is provided with the guide surface extended downwardly, so that one end of limited block be made to push against in slipping block and strip groove bottom Between gap, to improve the stability of upper millstone when upper millstone is directed at lower millstone.

Further, strip grooves inner wall is provided with several flexible strips along the setting of support rod length direction, the length of flexible strip Degree is 7-14cm, and the bottom end of flexible strip is abutted with the top of limited block.

By adopting the above technical scheme, when upper millstone is close to lower millstone, slipping block and flexible strip are abutted, to increase sliding The frictional force that block is subject to, i.e. staff can quickly feel that resistance becomes larger, and staff is reminded to slow down upper millstone direction The movement speed of lower millstone, reduction cause to damage upper millstone and lower millstone since the movement speed of upper millstone is excessive general Rate.

Further, the fixed elasticity layer of clamping groove inner wall, and elastic layer and support rod are interference fitted.

By adopting the above technical scheme, by setting elastic layer, the frictionally damage to support rod and link block is not only reduced, The frictional force that support rod is subject to is also increased, the mobile stability of upper millstone is improved.

Further, elastic layer inner wall offers several grooves being circumferentially arranged along elastic layer, height of the groove along support rod Degree direction is uniformly distributed.

By adopting the above technical scheme, by the way that groove is arranged, increase the restoring force of elastic layer, convenient for relative to the mobile bullet of support rod Property layer.

It further, further include the axis bolt parallel with upper millstone axis, one end of bolt is fixed with nut, the other end It is threadedly coupled across link block and with upper millstone.

By adopting the above technical scheme, detachable between realization link block and upper millstone by bolt, have structure simple The advantages of, and it is convenient for the quick-replaceable of elastic layer.

Further, lifting assembly includes screw rod and mounting base, and mounting base is fixed on body, mounting base offer with The thread groove of upper millstone coaxial line, screw rod are threadedly coupled with thread groove, and one end of screw rod and upper millstone are rotatablely connected.

By adopting the above technical scheme, by rotating screw rod, since screw rod and mounting base are rotatablely connected, to realize in drive Mill moves up and down, and has the advantages that structure is simple.

Compared with prior art, the utility model has the advantages that:

(1) lifting assembly drives upper millstone mobile towards lower millstone, under the action of link block and support rod, grinds in reduction The shaking of disk makes upper millstone and lower millstone rapid alignment, to improve work efficiency and mitigate the pressure of staff；

(2) stability of upper millstone is improved to realize dual clamping by setting strip grooves and slipping block；

(3) by setting flexible strip, staff is reminded to slow down movement speed of the upper millstone towards lower millstone, reduce due to The excessive probability for leading to the damage to upper millstone and lower millstone of the movement speed of upper millstone.
