Description
Technical field
The utility model relates to a kind of instrument in a kind of petroleum machinery workpiece mechanical processing process, specifically is meant the unidirectional adjusting sliding support of exempting to proofread.
Background technology
Machining is a kind of process that the appearance and size or the performance of workpiece is changed with processing equipment.The temperature shape attitude ﹐ that is in by processed workpiece is divided into cold working and hot-working: generally processing at normal temperatures, and the chemistry or the thing that do not cause workpiece change ﹐ mutually and claim cold working; Generally change ﹐ mutually and claim hot-working at add chemistry or the thing that worker ﹐ can cause workpiece that are higher or lower than the normal temperature state.Cold working can be divided into cut and pressure processing by the difference of processing mode; For example the turning of lathe processing just belongs to cold working.Workpiece is carried out in the process of turning processing at lathe, when the most important thing is that self length to heart process, particularly workpiece is longer; Workpiece deforms under the effect of self gravitation easily, causes centre-of gravity shift, therefore; For the turning than farm labourer's part, common way provides an eyelid retractor, makes workpiece under the pawl dish clamping of lathe; The other end is under the supporting role of eyelid retractor, and the axis of workpiece keeps level.But the model of eyelid retractor need be complementary with the model of workpiece, causes the scope of application of eyelid retractor very little, and limitation is very big.
The utility model content
The purpose of the utility model is to provide a kind of unidirectional adjusting sliding support of exempting to proofread; Overcome in present turning, the Grinding Process; The difficult problem that the model of eyelid retractor and the model of workpiece are difficult to mate solves chute simultaneously and is difficult to be positioned at collinear problem.
The purpose of the utility model realizes through following technical proposals:
The unidirectional adjusting sliding support of exempting to proofread of exempting to proofread comprises base plate, and said base plate is provided with one group of slide rail; Slide rail comprises two blend stops that are parallel to each other; Form chute between the blend stop, on said base plate, be installed with the abutment sleeve that is positioned at chute, in said abutment sleeve, be set with screw rod; Screw rod is provided with two spacing rings that lay respectively at the abutment sleeve both sides; On the outside screw rod of spacing ring, be provided with screw thread, and two sections screw threads is in the opposite direction, in chute, is provided with two eyelid retractors that lay respectively at the abutment sleeve both sides; In each said eyelid retractor, be provided with the screw that is complementary with screw flight, eyelid retractor and screw rod are connected through screw thread.In chute, be provided with an abutment sleeve that is fixedly mounted on the base plate, screw rod is installed in abutment sleeve, the part that screw rod is positioned at abutment sleeve is smooth cylinder; Screw rod is provided with two locating rings, and two locating rings lay respectively at the abutment sleeve both sides, on the screw rod in the locating ring outside, is provided with screw thread; The hand of spiral that is positioned at the abutment sleeve both sides is opposite, on eyelid retractor, is provided with screw, and screw rod and eyelid retractor are connected through screw thread; When regulating the screw rod of any end, the position of screw rod relative base plate under the effect of spacing ring does not change, because two sections hand of spirals are opposite on the screw rod; Two eyelid retractors are connected through screw and screw rod respectively, and the direction of motion of two eyelid retractors is opposite, i.e. move toward one another or deviate from motion; Through the rotation of adjusting screw(rod), can change two distances between the eyelid retractor, thereby make the model of itself and processing work be complementary; The set-up mode of one group of slide rail has overcome the check and correction problem of two chutes, has reduced the time of installing.
Described eyelid retractor comprises base; The width of base, height are complementary with the width of chute, the height of baffle plate; Base is provided with two gripper shoes parallel with blend stop, between two gripper shoes, roller is installed, and roller is connected on the gripper shoe through bearing; Said base is provided with the screw that is complementary with screw rod, and screw rod and base by thread are connected.Rotation for the ease of workpiece; Reduce the frictional force between workpiece and the eyelid retractor, base is provided with two parallel gripper shoes, between two gripper shoes, roller is installed; Roller is connected with two gripper shoes through bearing, and the distance at the axis of bearing and gripper shoe top is less than the radius of roller.
Said gripper shoe is positioned at the above part of bearing horizontal diameter for semicircle.In order to reduce gripper shoe and the possibility that workpiece directly contacts, gripper shoe is divided into two parts, its part that is positioned at the bearing horizontal diameter is for semicircle, and its radius is less than the radius of roller.
The lateral surface of said gripper shoe and the upper surface of base form step; On said blend stop, card article is installed; Distance between the said card article is less than the width of chute, and the distance between said two gripper shoe lateral surfaces is between the width of the distance of two card articles and chute.In order to limit the motion of eyelid retractor, prevent that eyelid retractor from doing the time spent and break away from chute receiving uneven external force, be provided with card article at the upper surface of blend stop; Distance between card article and the base plate is complementary with the substructure height of eyelid retractor; Simultaneously, the distance between two card articles is less than the width of chute, and the distance between two gripper shoe lateral surfaces is between the width of the distance of two card articles and chute; So; Can guarantee that eyelid retractor can be free to slide in chute, can limit the movement locus of eyelid retractor again, prevent that eyelid retractor breaks away from chute.
At least the end at described screw rod is provided with double-screw bolt.Say that further the rotation of screw rod for ease can be provided with double-screw bolt in the one or both ends of screw rod, suit proper tools on double-screw bolt, rotating screw bolt reaches laborsaving, convenient purpose of regulating easily.
The utility model compared with prior art has following advantage and beneficial effect:
The unidirectional adjusting sliding support that 1 the utility model exempts to proofread, when regulating the screw rod of any end, the position of screw rod relative base plate under the effect of spacing ring does not change; Because two sections hand of spirals are opposite on the screw rod, two eyelid retractors are connected through screw and screw rod respectively, and the direction of motion of two eyelid retractors is opposite; Be move toward one another or deviate from motion; Through the rotation of adjusting screw(rod), can change two distances between the eyelid retractor, thereby make the model of itself and processing work be complementary; The set-up mode of one group of slide rail has overcome the check and correction problem of two chutes, has reduced the time of installing;
The unidirectional adjusting sliding support that 2 the utility model exempt to proofread, eyelid retractor is provided with roller, through the mode that roller contacts with workpiece, has reduced the frictional force between workpiece and the eyelid retractor, has effectively overcome the locking phenomenon between workpiece and the eyelid retractor;
The unidirectional adjusting sliding support that 3 the utility model exempt to proofread, blend stop is provided with card article, the engagement limits through card article and blend stop the running orbit of eyelid retractor, effectively prevent the disengaging of eyelid retractor.
