Description
Technical field
The utility model relates to the knurled wheel quick replacement device in a kind of channelling machine, belongs to parts in the channelling machine, can realize the quick-replaceable function of knurled wheel.
Background technology
Channelling machine is mainly used on the tube wall of pipe fitting and suppresses groove, existing channelling machine comprises the main shaft that rolls the wheel and have knurled wheel, the periphery of rolling wheel has a circle boss, the periphery of knurled wheel has a circle and rolls the groove that the boss on the wheel is complementary, be implemented in indent on the tube wall of pipe fitting by the extruding of rolling between wheel and the knurled wheel, the pipe fitting of different tube diameters need use the knurled wheel of different size.In present channelling machine, knurled wheel and main shaft are connected as a single entity, the main shaft that promptly has knurled wheel is an integral structure, if in the time of will on same channelling machine, suppressing the pipe fitting groove of different tube diameters, need to change whole main shaft and just can reach the purpose of changing knurled wheel, need whole frame be disassembled from base and change main shaft, workload is equivalent to ressemble a channelling machine, waste time and energy, and require operating personnel to reach certain professional standards.This shows that the applicable surface of existing channelling machine is narrower, when needing the pipe fitting of compacting different tube diameters, inefficiency, operation easier is big, the production cost height.In case and knurled wheel part occurs and damage, and needs to change whole main shaft, the maintenance cost of equipment is higher.
The utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, high efficiency, and it is convenient to change knurled wheel, can improve the knurled wheel quick replacement device in the channelling machine of channelling machine applicable surface.
The technical scheme in the invention for solving the above technical problem is: the knurled wheel quick replacement device in this channelling machine comprises frame, piston rod, slide block, main shaft, outer wall has the knurled wheel of a circle groove and the wheel that rolls that outer wall has a circle boss, described groove and boss are complementary, described slide block and main shaft are installed on the frame, the described wheel that rolls is installed on the slide block, one end of described piston rod is fixed on the slide block, its characteristics are: also comprise flat key and clamp nut, one end of described main shaft is provided with the screw thread that is complementary with clamp nut, the outer wall of this main shaft is provided with the outside keyway that is complementary with flat key, described outside keyway is arranged in main shaft and is provided with threaded one, the inwall of described knurled wheel is provided with the internal keyway that is complementary with flat key, this knurled wheel is sleeved in the main shaft screwed one, described internal keyway and outside keyway align, groove on the described knurled wheel and the boss that rolls on the wheel align, described flat key is fixed in the gap that internal keyway and outside keyway surround, described clamp nut is fixed on the screw thread of main shaft one end, and the front end of this clamp nut withstands on the knurled wheel.Make the utility model to change knurled wheel easily thus, improved operating efficiency.
One that is provided with outside keyway in the main shaft described in the utility model is the truncated cone-shaped structure.Make clamp nut can be more firm knurled wheel is locked on the main shaft thus.
Described in the utility model roll the wheel be positioned at knurled wheel directly over.Make the utility model can better suppress the groove on the pipe fitting wall thus.
Outside keyway described in the utility model is arranged on the main shaft along the axial direction of main shaft.Make that thus flat key is better to the locating effect of knurled wheel in the utility model.
The radical of flat key described in the utility model is one.Make structure of the present utility model more simple thus.
The utility model compared with prior art, have the following advantages and effect: knurled wheel is positioned on the main shaft by flat key, rotation by main shaft can drive knurled wheel and rotate, and by clamp nut knurled wheel is locked on the main shaft, make knurled wheel to cooperate to roll groove on the wheel load tubulation spare wall.Because knurled wheel fixes with main shaft by flat key and clamp nut, make that dismounting and installation between knurled wheel and the main shaft are comparatively convenient, when channelling machine need be suppressed the pipe fitting of different tube diameters, replacing knurled wheel that can be easily and fast, improve operating efficiency, increased the applicable surface of channelling machine.
Because knurled wheel is fixed on the main shaft by flat key and clamp nut, when damaging appears in knurled wheel, only need to change knurled wheel and get final product, need not main shaft is changed, can save the accessory cost more than 2/3.
The utility model is simple in structure, and the replacing of knurled wheel is easy, is convenient to safeguard and maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment:
Referring to Fig. 1, knurled wheel quick replacement device in the present embodiment channelling machine comprises piston rod 1, slide block 2, rolls wheel 3, clamp nut 4, knurled wheel 5, flat key 6, main shaft 7 and frame 8, wherein the radical of flat key 6 is one, and the flat key 6 more than also can be set in the utility model according to actual needs.
Clamp nut 4 in the present embodiment is fixed on the screw thread of main shaft 7 one ends by screw thread, and the front end of clamp nut 4 withstands on the knurled wheel 5, thereby knurled wheel 5 is locked on the main shaft 7 firmly, make main shaft 7 in carrying out rotating process, the groove on the knurled wheel 5 can be all the time with roll wheel 3 convex platforms and align.
Piston rod 1 in the present embodiment is connected with hydraulic means 10 in the channelling machine, move up and down by hydraulic means 10 control piston bars 1, the other end of main shaft 7 is connected with reductor 11 by the shaft coupling in the channelling machine 9 in the present embodiment, can drive main shaft 7 by reductor 11 and rotate.When channelling machine carries out work, the pipe fitting of groove to be pressed is enclosed within on the knurled wheel 5, with reductor 11 is power source, driving is fixed on knurled wheel 5 rotations on the main shaft 7, under the control of hydraulic means 10, the rolling wheel 3 that piston rod 1 drive is installed on the slide block 2 moves down until rolling the outer wall that the boss of taking turns on 3 compresses pipe fitting, under the effect of frictional force, knurled wheel 5 drives the pipe fitting rotation, pipe fitting drives and rolls wheel 3 rotations, thereby constantly reduce to roll the gap between wheel 3 and the knurled wheel 5, the periphery that finally is implemented in tube wall carries out the function of indent.
Because the pipe fitting of different tube diameters has different requirements to the indent size on the tube wall, when processing the pipe fitting of different tube diameters, need to change the knurled wheel 5 of corresponding specification, present embodiment can be realized the quick replacing of knurled wheel having improved operating efficiency greatly by clamp nut 4.
Above content described in this specification only is to the explanation of the utility model structure example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
