Description

Unidirectional adjusting sliding support
Technical field
The present invention relates to a kind of instrument in a kind of petroleum machinery workpiece mechanical processing process, specifically be meant unidirectional adjusting sliding support.
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; The most important thing is heart process; When particularly self length of workpiece was longer, workpiece deformed 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.
Summary of the invention
The object of the present invention is to provide a kind of unidirectional adjusting sliding support, 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.
The object of the invention is realized through following technical proposals:

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; 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; Upper surface at blend stop is provided with card article; Distance between card article and the base plate is complementary with the substructure height of eyelid retractor; Simultaneously; Distance between two card articles is less than the width of chute; 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 present invention compared with prior art has following advantage and beneficial effect:
The unidirectional adjusting sliding support of 1 the present invention; On base plate, be installed with abutment sleeve; Screw rod is sleeved in the abutment sleeve; And screw rod is provided with two locating rings that lay respectively at the abutment sleeve both sides; Screw rod is connected through threaded engagement with eyelid retractor; And the hand of spiral that is positioned at the abutment sleeve both sides is opposite; Pass through rotating screw bolt; Distance between can the adjustable support device; Realized the problem that eyelid retractor and workpiece model are complementary; Through regulating, make the present invention can adapt to the workpiece of a plurality of models, increased usage range;
The unidirectional adjusting sliding support of 2 the present invention, 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;
