Abstract
The invention discloses an auxiliary clamping jaw for machining of internal teeth of a ribbed pipe. The auxiliary clamping jaw comprises a pushing rod, at least one fixed half clamping jaw body and moveable half clamping jaw bodies, wherein the number of the fixed half clamping jaw bodies is equal to that of the moveable half clamping jaw bodies. Each fixed half clamping jaw body is provided with a first opening. One end of each moveable half clamping jaw body is provided with a second opening. The middle of each moveable half clamping jaw body is hinged to the corresponding fixed half clamping jaw body. The other end of each moveable half clamping jaw body is hinged to the pushing rod. The second openings can be moved towards the first openings so that the space used for clamping a ribbed pipe blank can be formed. The auxiliary clamping jaw is simple in structure, convenient to use and practical.
Description
Technical field
The present invention relates to a kind of turning on slender workpieces positioner, be specifically related to the auxiliary jaw of ribbed pipe internal tooth processing.
Background technology
Ribbed pipe is the extraordinary tube heat exchanging component of heat transfer effect in electrical equipment, can reach the object of energy-conserving and environment-protective.Ribbed pipe main structure comprises light pipe, on light pipe inner surface, plow goes out internal tooth, thus entirety constitutes a 3-D solid structure, effectively improve the phase-change heat-exchange in the heat convection of monophasic fluid in pipe and pipe, then three current internally finned tubes add man-hour due to cantilever long, easily occur bending and deformation, thus reduce processing precision of products and qualification rate.
Summary of the invention
For the defect that above-mentioned prior art exists, the object of the present invention is to provide a kind of auxiliary jaw of ribbed pipe internal tooth processing that can improve ribbed pipe machining accuracy, qualification rate.
For achieving the above object, technical scheme of the present invention is: the auxiliary jaw of ribbed pipe internal tooth processing, comprise push rod, at least one fixes half jaw and activity half jaw equal with fixing half jaw quantity, fix half jaw and be provided with the first opening, movable half jaw one end is provided with the second opening, hinged with geometrical clamp corpus unguis in the middle part of movable half jaw, the movable half jaw other end is hinged with push rod, and the second opening can to the first harness motion to form the space clamping ribbed pipe blank; Described half jaw of fixing is two and one-body molded, and two the first openings fixing half jaw are oppositely arranged; Movable half jaw is two, and two activity half jaws share a push rod.
Compared with prior art, the invention has the advantages that: under using state, under push rod thrust, second opening of movable half jaw one end is close to the first opening, and forms the space of clamping ribbed pipe blank gradually, and now push rod halts, and ribbed pipe is clamped; After machining, push rod retreats, and second opening of movable half jaw one end away from the first opening, thus unclamps ribbed pipe; Movable half jaw is two, and two activity half jaws share a push rod, can play a supporting role to two root pipes simultaneously, and compact conformation is effective.The present invention is convenient and practical, can add man-hour at ribbed pipe, plays the effect of supplemental support, prevents ribbed pipe from causing bending distortion because cantilever is long, improves ribbed pipe machining accuracy, improve product percent of pass.
Further, push rod is by cylinder or hydraulic oil cylinder driving, simple and practical.
Further, also comprise guide rail, holder and localization handspike, fix half jaw, cylinder or oil cylinder and be all located at holder top, be connected with slide bottom holder, localization handspike one end and stationary jaw removably connect, the position relationship of half jaw, movable half jaw and ribbed pipe is fixed in convenient adjustment, improves job area of the present invention.
Further, holder is provided with limit switch, and localization handspike is provided with triggering block, when movable half jaw with fix half jaw clamp ribbed pipe time, triggering block can facilitate the process of control cylinder or oil cylinder, prevents ribbed pipe to press from both sides bad.
Further, holder with fix for bolt is connected between half jaw, installation for convenience detach.
Accompanying drawing explanation
Fig. 1 ribbed pipe internal tooth of the present invention processing structural representation of auxiliary jaw embodiment one.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Embodiment one:
As shown in Figure 1, the auxiliary jaw of ribbed pipe internal tooth processing, comprise push rod 31, two and fix half jaw and two activity half jaws, fix half jaw and be provided with the first opening, movable half jaw one end is provided with the second opening, described half jaw of fixing is two and one-body molded, comprise fix half jaw 11 and under fix half jaw, 12, two the first openings fixing half jaw and be oppositely arranged; Movable half jaw is two, comprises movable half jaw 21 and lower movable half jaw 22, two activity half jaws share push rod 31, can play a supporting role to two root pipes simultaneously, and compact conformation is effective; Upper movable half jaw 21 with on to fix half jaw 11 hinged, the right-hand member of lower movable half jaw 22 and under to fix half jaw 12 hinged, in the middle part of hinged movable half jaw 21 of upper brace 311 left end, upper brace 311 right-hand member and push rod 31 hinged, in the middle part of hinged lower movable half jaw 1 of lower brace 312 left end, lower brace 312 right-hand member and push rod 31 hinged, the second opening can to the first harness motion to form the space of clamping ribbed pipe blank; Also comprise guide rail 51, holder 52 and localization handspike 41, on fix half jaw 11, fix half jaw 12 down, cylinder 3 is all located at holder 52 top, be slidably connected with guide rail 51 bottom holder 52, guide rail 51 is fixed in frame 5, localization handspike 41 one end branch sleeve 42, sleeve 42 one end is threaded with the lower contiguous block 121 fixing half jaw 12 bottom, convenient adjustment fixed half jaw 11, fix half jaw 12, upper movable half jaw 21 and lower movable half jaw 22 and the position relationship of ribbed pipe down, improve job area of the present invention.
Holder 52 is provided with limit switch, and localization handspike 41 is provided with triggering block, when movable half jaw with fix half jaw clamp ribbed pipe time, by limit switch can prevent control positioning cylinder 4 process excessive, prevent ribbed pipe to press from both sides bad.
Under using state, under push rod 31 thrust, second opening of movable half jaw one end is close to the first opening, and forms the space of clamping ribbed pipe blank gradually, and now push rod 31 halts, and ribbed pipe is clamped; After machining, push rod 31 retreats, and second opening of movable half jaw one end away from the first opening, thus unclamps ribbed pipe; The present invention is convenient and practical, can add man-hour at ribbed pipe, plays the effect of supplemental support, prevents ribbed pipe from causing bending distortion because cantilever is long, improves ribbed pipe machining accuracy, improve product percent of pass.
Embodiment two:
With embodiment one unlike, cylinder is changed to oil cylinder, positioning cylinder transposition positional cylinder.
