Abstract
The utility model relates to a puller, in particular to a heating vibration puller solving the problem that the traditional puller is difficult to disassemble some fastening parts with tighter matching on shafts. The heating vibration puller comprises an ejector rod and a claw connected with the ejector rod, wherein the end of the ejector rod is installed with a vibrator with an adjustable vibration frequency. The heating vibration puller simultaneously also comprises a set of high-frequency induction heaters, one end of each high-frequency induction heater is installed with a magnet. When the heating vibration puller is used, the high-frequency induction heaters rapidly heat the outer surfaces of the disassembled parts so that the interference degree among the disassembled parts is reduced, and meanwhile, the disassembled parts generate intensive resonance under the action of the vibrator so that the frictional force among the disassembled parts is further greatly reduced. Aiming at the condition of overlarge frictional force among the disassembled parts, the heating vibration puller greatly reduces the frictional force among the disassembled parts by adopting the modes of installing the vibrator on the ejector rod of the puller to forcibly vibrate the disassembled parts and additionally providing heating devices, thereby solving the problem of difficult disassembly of the original puller.
Description
Technical field
The utility model relates to and draws horse, is specially a kind of heating vibration screw extractor.
Background technology
Draw horse to be also referred to as thruster, be widely used in dismantling axles such as various shaft couplings, gear, bearing, belt pulley and tighten part, it is made of with the hook two parts that are connected (or hinged) with push rod push rod, push rod is divided into screw rod and two kinds of forms of jack, and hook is divided into two kinds of two pawl formulas and three-pawl types, catches the object that draws with hook during use, rotary screw formula push rod or eject the jack type push rod, push rod is steadily advanced forward, and claw hook is corresponding to be retreated, being drawn object to pull out.
Existing draw horse in dismounting some cooperate when the axle of pine tightens part very convenient effectively, but some cooperate tighter axle to tighten especially unusual difficulty sometimes during larger-size part of part in dismounting, reason is owing to the excessive frictional force that causes of the assembling magnitude of interference between the demolition part is very big, the pulling capacity of drawing horse to produce is not enough to overcome this frictional force, so demolition part can not be pulled out.Because resistance is crossed ambassador's hook and can not will be drawn object normally to pull out, can not normally eject owing to push rod simultaneously, make La Manei accumulate a large amount of mechanical energy, may cause accident, serious threat site operation personnel's safety and the safety that is disassembled equipment such as being drawn object fracture or hook unhook.
Summary of the invention
The utility model draws horse to be difficult to dismantle the problem that the tighter axle of some cooperations tightens part in order to solve to have now, and a kind of heating vibration screw extractor is provided.
The utility model is to adopt following technical scheme to realize: heating vibration screw extractor, comprise push rod and the hook that is connected with push rod, the adjustable vibrator of vibration frequency is installed in the end of push rod, also comprise one group of high frequency induction heater simultaneously, an end of each high frequency induction heater is equipped with magnet.During use, earlier high frequency induction heater is adsorbed on the surface of demolition part, according to the size on the surface of demolition part or the requirement of programming rate, the high frequency induction heater of absorption respective numbers, heating vibration screw extractor is connected with demolition part and grants suitable pretightning force then, vibrator and push rod become to vibrate simultaneously, produce simultaneously the integral body of resonance, and will vibrate, resonate and pass to demolition part by push rod, hook.Connect high frequency induction current, the outer surface of demolition part is heated rapidly, keep temperature-resistant and the axle that is disassembled is basic, under the effect of expanding with heat and contract with cold, demolition part expands and axle does not expand, degree of interference fit between the demolition part is descended, thereby significantly reduce the frictional force between the demolition part; Connect the power supply of vibrator simultaneously, adjust both oscillator frequency, when vibration frequency is adjusted to the resonant frequency scope of demolition part, demolition part produces strong resonance, frictional force between the demolition part further declines to a great extent, at this moment drawing the application of force on the push rod of horse, demolition part will easily be separated.
The utility model is at the excessive situation of the frictional force between the demolition part, the mode of vibrator forced vibration demolition part being installed and setting up heater on the horse push rod is being drawn in employing, significantly reduce the frictional force between the demolition part, thereby solve original situation of drawing horse dismounting difficulty.The utility model draws horse to compare with tradition; can significantly reduce the frictional force between the demolition part; thereby significantly reduce the pulling capacity of drawing horse; can protect the safety of demolition part and site operation personnel's personal safety; simultaneously because the significantly raising of this heating vibration screw extractor ability to work; the drawing ability specification of drawing horse to compare heating vibration screw extractor with tradition in the middle of same field-strip descends 80%; thereby make the corresponding minimizing 80% of the volume and weight that draws horse; significantly reduce the cost of equipment that draws horse, alleviate the labour intensity of drawing operation.Its reasonable structural design had both guaranteed vibrator forced vibration demolition part, guaranteed that again vibrator avoids excessive pressure and damage; Simultaneously, heater is made as independently blockage (being that heater is one group of high frequency induction heater) of heating system, one end setting-in magnet, can the respective numbers heater be installed according to the different appearance and sizes of heating object during use, to guarantee to add heat, programming rate, this structural design novelty, uniqueness, easy to use.
