Abstract
The invention relates to a manual-adjusting expansion and contraction device. An expansion and contraction shaft is arranged in a base, a kidney-shaped groove is formed in the base, one end of a locking bolt penetrates the kidney-shaped groove and is in threaded connection with the expansion and contraction shaft while the other end of the same is in threaded connection with a locking handle, a rack is arranged below the expansion and contraction shaft, a gear shaft is penetratingly mounted in the base and meshed with the rack, shaft sleeves are mounted at two ends of the gear shaft in a sleeved manner, and a handwheel is mounted at at least one end of the gear shaft. The manual-adjusting expansion and contraction device is simple in structure, compact in size and convenient to operate; the gear shaft is rotated by rotating the handwheels, and the gear shaft is meshed with the expansion and contraction shaft, so that a rotating pair is converted into a forward or backward moving pair to realize slight adjusting, and the manual-adjusting expansion and contraction device is accurate and convenient to position and wide in application range.
Description
Technical field
The present invention relates to adjust telescopic equipment, relate in particular to the manual adjustment retractor device for manipulator.
Background technology
Manipulator is widely used in boiler, pressure vessel, and oil, chemical industry, the manufacturings such as machinery, mainly realize the inside and outside longitudinal joint of drum drum and other circle tube member and the automatic welding of inside and outside circumferential weld.During due to the welding original state, the welding torch position of manipulator and position while welding, or not a place, at this moment need to regulate welding torch position, by manipulator, regulate in the past, and the manipulator volume is difficult for more greatly regulating, and can't realize the trace adjusting, and polarization is poor.
Summary of the invention
The applicant, for above-mentioned existing issue, provides a kind of simple in structure, easy to operate manual adjustment retractor device, has accurate positioning, advantage applied widely.
The technical solution adopted in the present invention is as follows:
Manually adjust retractor device and comprise pedestal, install telescopic shaft in pedestal, also have kidney slot on pedestal, an end of clamping screw runs through kidney slot and is threaded with telescopic shaft, the other end of the clamping screw set lever that is threaded; Be provided with tooth bar below telescopic shaft, the tooth axle run through be installed in pedestal and with the tooth bar engagement, the two ends suit axle sleeve of tooth axle, be equipped with handwheel at least one end of described tooth axle.
Its further technical scheme is:
Have installing hole on described pedestal;
The middle part of described clamping screw is provided with columnar portion, described columnar portion can with the kidney slot clamping of pedestal;
The cross section of described set lever, handwheel is "T"-shaped.
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, volume is small and exquisite, easy to operate, by rotating handwheel, the tooth axle is rotated, due to tooth axle and telescopic shaft engagement, revolute pair is converted into to the moving sets that advances or retreat, reach the purpose that trace is adjusted, utilize handle to be locked, accurate positioning is convenient, applied widely simultaneously.
The accompanying drawing explanation
Fig. 1 is front view of the present invention.
The side view that Fig. 2 is Fig. 1.
The top view that Fig. 3 is Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, Figure 2 and Figure 3, the present invention includes pedestal 1, be provided with through hole in pedestal 1, device telescopic shaft 8 in through hole, as shown in Figure 1, Figure 3, also have kidney slot 101 on pedestal 1, one end of clamping screw 3 runs through kidney slot 101 and is threaded with telescopic shaft, the other end of clamping screw 3 set lever 4 that is threaded, as shown in Figure 3, the middle part of clamping screw 3 is provided with columnar portion 301, columnar portion 301 can with kidney slot 101 clampings of pedestal 1, and play guiding and restriction telescopic shaft collapsing length.As shown in Figure 1, be provided with tooth bar 801 below telescopic shaft 8, tooth axle 6 run through be installed in pedestal 1 and with tooth bar 801 engagements, as shown in Figure 2, the two ends of tooth axle 6 suit axle sleeve 5, axle sleeve 5 is connected with pedestal by securing member, at least one end of tooth axle 6, handwheel 7 is installed.
Also have installing hole on pedestal 1, as shown in Figure 1, the cross section of set lever 4, handwheel 7 is "T"-shaped.
Specific works process of the present invention is as follows:
As shown in Figure 1, by connecting bolt 2, installing hole 102 is connected pedestal 1 with the transverse arm end of manipulator, the welding gun (not shown) for welding is installed in the end of telescopic shaft 8, by rotation hand wheel 7, make tooth axle 6 make revolute, due to the gear end of tooth axle 6 and tooth bar 801 engagements of telescopic shaft 8, revolute can be converted to thus to the moving sets (advancing and retreating by handwheel positive and negative of telescopic shaft transfers realization) of telescopic shaft 8, after telescopic shaft 8 moves to correct position, by rotational lock handle 4, locking telescopic shaft 8 limits it and is moved, then start welding job.
The present invention is simple in structure, volume is small and exquisite, easy to operate, by rotating handwheel, the tooth axle is rotated, due to tooth axle and telescopic shaft engagement, revolute pair is converted into to the moving sets that advances or retreat, reach the purpose that trace is adjusted, utilize handle to be locked, accurate positioning is convenient, applied widely simultaneously.
Above description is explanation of the invention, is not that limited range of the present invention is referring to claim, in the situation that, without prejudice to basic structure of the present invention, the present invention can do any type of modification to the restriction of invention.
