Description

A kind of removable pulley mechanism

Technical field

The tooling device field that the present invention relates to be welded, especially a kind of removable pulley mechanism.

Background technology

Tooling devices such as welding machine, soldering turret, slide rail, coaster use in the workshop that is welded in a large number; And the interpolation working strength in slide rail, coaster later stage is very big; Therefore, in early stage when planning, increase equipment such as welding machine, soldering turret for fear of the later stage and reserve a little useless slide rail, coasters; In the process of project running or in the project end, can cause a large amount of useless idlenesses of equipment, and then cause waste.In addition, existing supratrochlear vertical pulley and horizontal pulley all be form fix through riveted joint on the coaster body, just need integral replacing if in use run into the situation that increases or change coaster.The situation in just present workshop, the problems referred to above do not obtain enough attention, even if in the workshop that is welded of having produced in batches, a lot of idle slide rail, coasters are arranged still, have both increased the cost of project, have wasted resource again.

Summary of the invention

The object of the present invention is to provide a kind of simple in structure, removable pulley mechanism of being convenient to installation and removal.

For realizing above-mentioned purpose; The present invention has adopted following technical scheme: removable pulley mechanism; Comprise coaster body and the slide rail that can supply the coaster body in its chute, to slide; Described slide rail is the strip hollow tube body, and the cross section of slide rail roughly is square, and the center position of chute lower surface cell wall is offered a strip hole along the length direction of slide rail; The both sides that chute lower surface cell wall is positioned at strip hole are also offered and can be supplied the coaster body to put into its through hole, and blocking piece is placed corresponding to the position of through hole in the outside of slide rail.

Can know by technique scheme; Slide rail of the present invention can carry out installation and removal with the coaster body easily; Coaster and slide rail can conveniently increase and change, and need not whole coaster and slide rail to be changed, and can reduce the cost of budget when planning being welded.Advantage such as that the present invention has is simple in structure, cost is low, manufacturing process is simple.

The specific embodiment

A kind of removable pulley mechanism; The slide rail 20 that comprises coaster body 10 and can supply coaster body 10 in its chute, to slide; Described slide rail 20 is the strip hollow tube body, and the cross section of slide rail 20 roughly is square, and the center position of chute lower surface cell wall is offered a strip hole 23 along the length direction of slide rail 20; The both sides that chute lower surface cell wall is positioned at strip hole 23 are also offered and can be supplied coaster body 10 to import its vacancy portion; Blocking piece 30 is placed corresponding to the position of vacancy portion in the outside of slide rail 20, offers on the described coaster body 10 can supply and suspend the installing hole 16 that welding machine is connected in midair, like Fig. 1,2,3, shown in 5.

In conjunction with Fig. 1,2,3,5,7; Described coaster body 10 is along two first pulley spindles 11 of the upwards symmetrical welding of vertical; Two second pulley spindles 12 of position symmetry welding on the coaster body 10 between two first pulley spindles 11; The axially length direction axial, coaster body 10 with first pulley spindle 11 of second pulley spindle 12 is vertical; Help wheel 13, road wheel 14 to be installed in respectively on the installation end of first pulley spindle 11, second pulley spindle 12; Chute lower surface cell wall is positioned to be offered two first through hole 21 and two that can supply to help wheel 13 to import it successively and can supply road wheel 14 to import its second through hole 22 on the both sides of strip hole 23, the width between the chute two side matches with the diameter of helping wheel 13, in other words the width between the chute two side greater than and take turns 13 diameter near support.In the present invention; Described vacancy portion is meant first through hole 21 and second through hole 22; The size that the shape of first through hole 21 and second through hole 22 is semi-circular hole 22, the first through holes 21 and second through hole 22 will guarantee that the support wheel 13 of coaster body 10 can waltz through and put into slide rail 20 with road wheel 14.

Be further described below in conjunction with Fig. 1,2,3,4,5,6,7,8 couples of the present invention.

Blocking piece 30 is installed corresponding to the position of two first through holes 21, two second through holes 22 in the outside of described slide rail 20; Blocking piece 30 is the relative two halves formula of opening; Be provided with protrudingly 31 on the blocking piece 30 corresponding to the position of first through hole 21, second through hole 22, the shape of this convexity 31 matches with the shape of first through hole 21, second through hole 22 respectively, and two halves formula blocking piece 30 extends upward; Transition is set; And be fixedly connected on the slide rail 20 through bolt 40, perhaps adopt other modes to accomplish being connected of blocking piece 30 and slide rail 20, be intended to realize dismountable connected mode.Influence the slip of coaster body 10 even can bring bigger resistance because removable pulley mechanism first through hole 21 in the process of back and forth operation is understood with second through hole 22; Even may be stuck in first through hole 21 and second through hole, 22 places that slide rail 20 is offered; Can blocking piece 30 be installed in the outside of slide rail 20; The madial wall that guarantees slide rail 20 chutes is complete plane with the contact-making surface of helping wheel 13 and road wheel 14; Promptly guarantee the inner chamber of slide rail 20 and slide rail 20 striking resemblances of not offering first through hole 21 and second through hole 22, meanwhile also avoid the intensity of slide rail 20 is impacted.

Described coaster body 10 is provided with damping rubber block 15 along the two ends of its length direction; Two coasters that close on are the mutual frictional impact of unavoidable meeting when sliding; Be provided with rubber buffer module 16 at the two ends of coaster body 11; Be used to alleviate mutual impulsive force, guarantee that removable pulley mechanism can not be damaged owing to mutual collision in the process of operation; Also reduced greatly simultaneously owing to colliding the noise that produces each other.

When need be when appropriate position increases coaster 10; Take off bolt 40 and blocking piece 30 at first successively; Then the support wheel 13 of coaster body 10 is put into slide rail 20 with road wheel 14 through first through hole 21 and second through hole 22 of slide rail 20; The last correspondence position that again blocking piece 30 is installed in first through hole 21 and second through hole 22, construction bolt 40 is with fixing blocking piece 30 at last; When needs are dismantled, take off bolt 40 and blocking piece 30 successively, just can coaster body 10 be taken out through first through hole 21 and second through hole 22.

In sum, core of the present invention is on the chute cell wall of slide rail 20, to offer through hole, when mounted, through this through hole coaster body 10 is put into slide rail 20, and blocking piece 30 is installed to block through hole; In when dismounting, takes out in the through hole of directly coaster body 10 being offered from slide rail 20 and get final product, coaster body 10 and slide rail 20 can conveniently increase and change, and can reduce the cost of budget when planning being welded.Advantage such as that the present invention has is simple in structure, cost is low, manufacturing process is simple.
