Abstract
The utility model relates to a coaxial ratchet adjusting mechanism of a pipe cutting machine. Three corners or four corners of an oil cylinder body are matched with a vertical type guide rail and run up and down along the vertical type guide rail, a tension spring is connected with the oil cylinder body and drives an oil cylinder to return to the original position, synchronous ratchet clutch mechanisms used for locking the oil cylinder are arranged at the two sides of the oil cylinder body, and a cutter device is connected with the piston end part of the oil cylinder. The advantages of the coaxial ratchet adjusting mechanism are as follows: first, the adjusting range is wide, the adjusting speed is high, and the adjusting is simple as well as convenient; when in adjusting, only one hand is needed to pull a handle so as to lead meshed ratchet blocks to be separated, and then the cutter device can automatically return to the original position upwards with the function of the tension spring; the cutter device is pressed down by the other hand, and the hand which pulls the handle is loosened until a cutter wheel on the cutter device is in contact with the outer circle surface of a pipe to be cut, so as to lead the ratchet blocks to be automatically meshed with the function of a pressure spring and achieve the automatic locking of the oil cylinder; second, when the oil cylinder is in locking state and a ratchet mechanism cuts the pipe with the force continuously increasing, the rigidity of the mechanism is good, so as to not only reduce labor intensity of users, but also improve pipe cutting efficiency.
Description
Technical field
The utility model relates to a kind of can quick adjustment putting in place and the coaxial ratchet of pipe cutter governor motion of rigid locking, belongs to pipe cutting machine and makes the field.
Background technology
The impulse stroke of existing cutting machine is regulated two kinds of structures: a kind of is to be promoted by oil hydraulic system, power (jack) and operating point lay respectively at two ends of a rotating fulcrum, pull hydraulic lever, promoting large tank makes other end work cutter wheel slowly near workpiece, not only process is slow, and influences work efficiency; Another kind is to be regulated by screw mandrel, and not only the rigidity of structure is relatively poor, and efficient is very low in actual applications.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, designing a kind of one is that work cutter wheel can either quick adjustment be put in place, lock in certain scope, can make its latched position overlap consistent fully with work center of effort again; The 2nd, can either make Knife cutting device keep favorable rigidity in when work, can guarantee that again the cutter wheel gets into when being cut material not cutter relieving, reach the coaxial ratchet of pipe cutter governor motion of quick adjustment and rigid locking.
Design: in order to realize above-mentioned purpose of design.1, cylinder block triangle or four jiaos are one of characteristics of the present utility model with the vertical rail coupling and along the design that vertical rail moves up and down.The purpose of doing like this is: because Knife cutting device is connected with in-oil cylinder piston end surface, therefore oil cylinder is designed to be able to along the vertical rail structure of operation freely up and down, can make the cutter wheel in the Knife cutting device touch the outer round surface of pipe to be cut apace, thereby improve its operating efficiency.2, extension spring is connected with cylinder block and drives the design that oil cylinder resets, and is two of characteristics of the present utility model.The purpose of doing like this is: cooperate (clutch) and produce and with after ratchet bar separates from the pilot hole of wallboard by turning handle and linkage drive ratchet piece because the ratchet bar that is arranged in synchronously the cylinder block both sides in the ratchet clutch and ratchet piece are clutch, its Knife cutting device is under the effect of tension spring tension, Knife cutting device retracted rise to original state (being the initial tension state of extension spring), that is to say that the function of extension spring has been guaranteed automatically reseting of Knife cutting device.3, the design of the synchronous ratchet clutch in cylinder block both sides is three of characteristics of the present utility model.The purpose of doing like this is: cooperate owing to the ratchet bar that is positioned at the cylinder block both sides in the synchronous ratchet clutch is clutch with the ratchet piece, when the pipe of different size is cut in the needs adjustment, as long as turning handle, by handle drivening rod mechanism, linkage drives the pilot hole of ratchet piece from wallboard and produces, the ratchet piece is separated with ratchet bar, press down Knife cutting device past with the another hand this moment, make the cutter on the Knife cutting device take turns the outer round surface that touches pipe to be cut, unclamp the hand of spanner handle then, linkage in the synchronous ratchet clutch forces the ratchet piece to rotate back in the wallboard and with ratchet bar under the stage clip effect and meshes, thereby reaches the purpose of locked cylinder.4, Knife cutting device and the design that the pistons end of oil cylinder is connected are four of characteristics of the present utility model.The purpose of doing like this is: Knife cutting device can either contact with the surface that is cut pipe apace with the operation up and down of oil cylinder, has guaranteed again in the Knife cutting device that cutter is taken turns to get into when being cut material not cutter relieving under the effect of oil cylinder piston.
Technical scheme: coaxial ratchet of pipe cutter governor motion, cylinder block triangle or four jiaos move up and down with the vertical rail coupling and along vertical rail, extension spring is connected with cylinder block and drives oil cylinder and resets, the cylinder block both sides are provided with synchronous ratchet clutch and are used for locked cylinder, and Knife cutting device is connected with the pistons end of oil cylinder.
The utility model is compared with background technology, and the one, adjusting range is big, and it is fast to regulate the speed, adjust simple and convenient, during adjustment, only need to pull handle, the ratchet piece of engagement is thrown off with a hand, its Knife cutting device can up reset under the effect of extension spring automatically, another hand toward pressing down, when the cutter wheel to Knife cutting device touches the outer round surface of pipe to be cut, unclamps the hand of spanner handle with Knife cutting device, the ratchet piece is engagement automatically under the effect of stage clip, reaches automatically locking oil cylinder; The 2nd, the ratch mechanism of oil cylinder under lock-out state is when cutting pipe, stressed continuous increases, and the rigidity of its mechanism is good, and is unaffected, so can greatly improve Pipe Cutting efficient again for the Pipe Cutting user reduces labor intensity.
