Description
Technical field
The utility model relates to injection machine apparatus field, is specifically related to the hydraulic jack with dismounting groove on a kind of guide sleeve.
Background technique
Conventional injection molding machine has 5 hydraulic jacks, oil cylinder guide copper sleeve wherein, piston rod is played to the effect of positioning and guiding, so the mixing ratio of oil cylinder guide copper sleeve external diameter and cylinder cover is tighter, material adopts tin bronze, because seal ring will be changed often, after just must first dismantling oil cylinder guide copper sleeve, just can change, but, due to cylinder cover internal diameter and oil cylinder guide copper sleeve major diameter fit tighter, oil cylinder guide copper sleeve is dismantled very difficult, in the process of dismounting, often cause this copper sheathing to damage even scrap, even if do not damage, also to tear open for a long time, and, be easy to produce the phenomenons such as scuffing to the surface of part in the process of dismounting, some producer is for the ease of dismounting, the comparatively drive fit of cylinder cover internal diameter and oil cylinder guide copper sleeve is used instead comparatively loose fit, although convenient disassembly is many, but positioning precision declines, have impact on oil cylinder quality.
Summary of the invention
Technical problem to be solved in the utility model is to provide the hydraulic jack with dismounting groove on a kind of guide sleeve, effectively avoid the deficiency in background technique, the precision of oil cylinder can be ensured, the dismounting of guide sleeve on oil cylinder can be facilitated again, oil cylinder quality is good again, can never the dimensional accuracy of part of damage needs and the roughness of part surface in the process of dismounting.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: with the hydraulic jack of dismounting groove on a kind of guide sleeve, comprise hydraulic jack, be located at the cylinder cover of hydraulic jack one end and hydraulic jack with the use of piston rod, be located in hydraulic jack and piston that piston rod is connected and fixed, be located between piston rod and cylinder cover for seal seal ring, be located on cylinder cover and piston rod played to the guide sleeve of positioning and guiding effect, be located at the cylinder tail of cylinder cover side, described guide sleeve is provided with an easy-to-dismount dismounting groove.
Structure is simple, easy and simple to handle, positioning precision is high, hydraulic jack is in the process of carrying out work, guide sleeve fixation, positioning precision is high, accurate control is played to the spacing guiding of piston rod, when seal ring changed by needs, only need insert in dismounting groove with instrument one end such as screw-drivers and outwards prize, just guide sleeve can be separated from cylinder cover, guide sleeve is dismantled convenient, the better quality of oil cylinder, in the process of dismounting can never part of damage need size, precision and part surface roughness.
As preferably, described guide sleeve comprises fastening section of being connected in cylinder cover, the dismounting section be connected on cylinder tail, and described dismounting grooved ring is located at outside dismounting section, the described side of dismounting groove and the outboard alignment of cylinder cover.
When clamping fixing to guide sleeve, fixed effect is better, the described side of dismounting groove and the outboard alignment of cylinder cover, when arranging dismounting groove, as far as possible by close outside the inner side of dismounting groove and cylinder cover, dismounting can be made easier, and when being exerted all one's strength by lever principle during dismounting, fulcrum more easily contacts.
As preferably, being provided with an axial section inside the dismounting section of described guide sleeve is T-shaped dustproof groove, be provided with between described guide sleeve and piston rod one with seal groove with the use of T-shaped annulus dust ring, described T-shaped annulus dust ring is located in dustproof groove.
As preferably, the length of described dismounting groove is 2 ~ 4mm, the degree of depth of described dismounting groove is 2 ~ 3mm, man-hour is being added to dismounting groove, mainly be processed into the circular groove of 2mm*2.5mm, after machine shaping, effectively can ensure the bulk strength of guide sleeve, in Long-Time Service, can not have an impact to the working life of guide sleeve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of this practical guide sleeve.
Embodiment
As depicted in figs. 1 and 2, with the hydraulic jack of dismounting groove on a kind of guide sleeve, comprise hydraulic jack 1, be located at the cylinder cover 4 of hydraulic jack 1 one end and hydraulic jack 1 with the use of piston rod 8, be located in hydraulic jack 1 and piston 2 that piston rod 8 is connected and fixed, be located between piston rod 8 and cylinder cover 4 for seal seal ring 3, be located on cylinder cover 4 and piston rod 8 played to the guide sleeve 5 of positioning and guiding effect, be located at the cylinder tail 6 of cylinder cover 4 side, described guide sleeve 5 is provided with an easy-to-dismount dismounting groove 10; Described guide sleeve 5 comprises fastening section 9 of being connected in cylinder cover 4, the dismounting section 11 be connected on cylinder tail 6, and described dismounting groove 10 ring is located at outside dismounting section 11, the side of described dismounting groove 10 and the outboard alignment of cylinder cover 4; Being provided with an axial section inside the dismounting section 11 of described guide sleeve 5 is T-shaped dustproof groove 12, be provided with between described guide sleeve 5 and piston rod 8 one with dustproof groove 12 with the use of T-shaped annulus dust ring 7, described T-shaped annulus dust ring 7 is located in dustproof groove 12; The length of described dismounting groove 10 is 2 ~ 4mm, and the degree of depth of described dismounting groove 10 is 2 ~ 3mm.
During real work, when seal ring 3 changed by needs, only cylinder tail 6 need be disassembled, then the tool card of one end flat such as screw-driver is received in dismounting groove 10, with cylinder cover 4 side for fulcrum is outwards prized, just can will disassemble easily from cylinder cover 4 with the close-connected guide sleeve 5 of cylinder cover 4, thus seal ring 3 is changed, when dismantling guide sleeve 5, because force bearing point is in dismounting groove 10, can never the dimensional accuracy that needs of part of damage and the roughness of part surface in the process of dismounting, make the longer service life of guide sleeve 5, working efficiency is higher, when choosing guide sleeve 5, preferentially choose copper sheathing, longer service life can be made, wear resistance is better, effectively avoid the deficiency in background technique, the precision of oil cylinder can be ensured, the dismounting of guide sleeve on oil cylinder can be facilitated again, oil cylinder quality is good.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
