Description
Technical field
The present invention relates to a kind of cylinder barrel surface treatment fixture.
Background technology
Cylinder guides piston in cylinder, carry out the cylindrical metal parts of straight reciprocating motion.Thermal energy is mechanical energy by expanding by working medium in cylinder; Gas receiving piston in compresser cylinder compresses and improves pressure.The housing of turbine, rotary engine etc. also claims cylinder usually.
Cylinder barrel is the main body of hydraulic cylinder, and its endoporus generally adopts the precise machining process manufactures such as boring, fraising, roll extrusion or honing, makes piston and seal thereof, supporting member can slide smoothly, thus ensure sealing effectiveness, reduce wear; Cylinder barrel will bear very large hydraulic coupling, therefore, should have enough strength and stiffness.
Cylinder barrel is generally a tubular part, end or be uncovered, or be provided with boss on the inwall of its end open-mouth, when carrying out Surface Machining to cylinder barrel is fixedly important step, how realizing better clamping is the problem that one of ordinary skill in the art are devoted to solve.
Summary of the invention
The invention is intended to provide a kind of cylinder barrel surface treatment fixture, be fixed to treat surface-treated cylinder barrel.
Cylinder barrel surface treatment fixture in this programme, comprise clamp body, the right side of clamp body has been bolted workbench, workbench is provided with semicircular boss, the partial contour that boss profile is uncovered with cylinder barrel mates, above clamp body upper table, thread connection has bolt, two of bolt be respectively equipped with from screw thread, the left end of bolt is connected on clamp body by hold-down nut, the right-hand member of bolt is through the cylindrical void in float plate, cylindrical void is positioned at vertical direction and coordinates with bolt-clearance, stage clip is connected with between float plate and clamp body, float plate contact stage clip another side be provided with traveling nut and thread connection at bolt right-hand member, the below of float plate is provided with jaw, jaw is provided with and bend into cylinder barrel inside and the clamping part compressing internal end surface on inner wall of cylinder boss.
When fixing, first placed by the boss on corresponding for cylinder barrel workbench, now cylinder barrel open section is by workbench shutoff, when still leaving the uncovered of part.Because float plate is provided with the cylindrical void of vertical direction, so float plate can move up and down in certain stroke, if the excessive length exceeding cylindrical void of shift motion, can by bolt blocks.Can stretch in cylinder barrel when float plate moves down rear clip-claw, and make retaining part end surface in inner wall of cylinder boss, then traveling nut is turned, order about float plate to move to clamp body, clamping part is progressively increased in the pressure on cylinder barrel boss in this process, coordinates the clamping realizing workpiece with workbench.The height that float plate can also be regulated to rise by hold-down nut, to adapt to different fixing processing environments.
Further, float plate is provided with vertical guide groove towards the one side of clamp body, clamp body is provided with pilot pin and embeds in guide groove.To retrain the rotation of float plate, and ensure the accuracy of its vertical motion.
Further, the two ends of float plate are equipped with pad.
Further, pilot pin is against the one end in guide groove is round end.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: clamp body 1, workbench 2, boss 3, workpiece 4, bolt 5, hold-down nut 6, traveling nut 7, float plate 8, jaw 9, cylindrical void 10, guide groove 11, pilot pin 12.
Embodiment is substantially as shown in Figure 1: the right side of clamp body bottom is detachably connected with workbench by bolt, workbench is provided with semicircular boss, boss profile and the uncovered the latter half outline of cylinder barrel, first the boss on corresponding for cylinder barrel workbench is placed, now cylinder barrel open section is by workbench shutoff, when the semicircle still leaving upper part is uncovered.
Clamp body top thread connection has the bolt of level, two of bolt is equipped with screw thread, the left end of bolt is connected on clamp body by hold-down nut, the right-hand member of bolt is through the cylindrical void in float plate, cylindrical void is positioned at vertical direction and coordinates with bolt-clearance, because float plate is provided with the cylindrical void of vertical direction, so float plate can move up and down in certain stroke, if the excessive length exceeding cylindrical void of shift motion, can by bolt blocks.
Be connected with stage clip between float plate and clamp body, the right flank of float plate be provided with traveling nut and thread connection at bolt right-hand member, the two ends of float plate are equipped with pad.
Float plate is provided with vertical guide groove towards the one side of clamp body, and the round end that clamp body is provided with pilot pin embeds in guide groove.
The below of float plate is provided with jaw, and jaw is provided with the clamping part bending into cylinder barrel inside, and clamping part is pressed on the inner face on inner wall of cylinder boss.Can stretch in cylinder barrel when float plate moves down rear clip-claw, and make retaining part end surface in inner wall of cylinder boss, then traveling nut is turned, order about float plate to move to clamp body, clamping part is progressively increased in the pressure on cylinder barrel boss in this process, coordinates the clamping realizing workpiece with workbench.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
