Embodiment
To describe technology contents of the present utility model, construction feature, the objects and the effects in detail, below in conjunction with implementation
Mode simultaneously coordinates accompanying drawing to be explained in detail.
Shown in reference picture 1, a kind of this new hydraulic line rail clamping device of offer, wherein, including holder body 1, two work
Gag 21 and two hydraulic pistons 22, the one end of holder body 1 is connected with movement parts (not shown), specifically by mounting hole
11 and the quick bolt of positioning hole 12 be fixed on movement parts, the other end of holder body 1 is symmetrical arranged piston successively from two lateral middle parts
To form grasping part, the grasping part is used to clamp line rail, the piston cap 21 and holder body 1 for lid 21 and hydraulic piston 22
It is fixedly connected, and hydraulic piston 22 can move horizontally in holder body 1.
The piston cap 21 and hydraulic piston 22 are tightly connected to form hydraulic space 23, specifically with the holder body 1
Ground, originally new also to include two the first sealing rings 31 and two the second sealing rings 32, corresponding two hydraulic pressure of the holder body 1 are lived
Plug 22 sets two the first sealed grooves 13, i.e. the first sealed groove 13 matches setting one by one with hydraulic piston 22, and this is first close
In embedded first sealed groove 13 of the matching of seal 31, first sealed groove 13 is ring-type, and such first sealing ring 31 can be close to
Hydraulic piston 22 is set, because hydraulic piston 22 can move in the horizontal direction according to being actually needed, therefore the first sealed groove
13 are located on holder body 1 the first sealing ring 31 can be avoided frequently to move, and stability is more preferable, in actual production, the first sealing
Circle 31 can use this spy's envelope, and frictional resistance is smaller, and hydraulic piston 22 preferably moves.Because piston cap 21 remains stationary as, two
Piston cap 21 is respectively equipped with the second sealed groove 211, in embedded second sealed groove 211 of second sealing ring 32 matching,
The holder body 1 is provided with the hydraulic circuit 14 connected with the hydraulic space 23, and holder body 1 is additionally provided with oil nozzle
Joint 15, to the hydrodynamic force of hydraulic piston 22 when hydraulic oil flows to hydraulic space 23 through hydraulic circuit 14 so that hydraulic piston
22 are clamped to the movement of line rail with realizing, because hydraulic coupling caused by hydraulic circuit 14 is uniform so that the uniform force of hydraulic piston 22
Stable, not only clamping is stable, is not also influenceed by alignment error and triggers line rail and lathe base to be deformed because of unbalance stress, and
Oil pressure pressure size is freely adjusted according to chucking power demand to be adjusted, it is very convenient.
Using recoil of spring, the preferred embodiment new as this, in addition to piston magnet after the clamping of hydraulic piston 22
4, the piston magnet 4 is fixedly connected on piston cap 21 and uses iron close to the side of the hydraulic piston 22, the hydraulic piston 22
Material is molded and hydraulic piston 22 sets slot to make way close to the side of the piston cap 21 matching piston magnet 4, in this way, piston
Magnet 4 has magnetic force all the time to hydraulic piston 22, and when hydraulic oil pressure release, hydraulic coupling is less than magnetic force, and magnet can pass through resigning trough
Attached hydraulic piston 22, the reset running of hydraulic piston 22 is realized, it is originally new that rebounding mechanism is used as using piston magnet 4, relative to
Compression spring, the length meeting lost its bounce of compression spring usage time one, and the magnetic force of magnet exists all the time, and fatigue damage will not occur
Situation, service life is longer.
Preferably, originally new also to include sunk screw 5, the piston magnet 4 opens up counterbore, and the hardness of piston magnet 4 compares
Greatly, counterbore is opened up in advance, and the head insertion counterbore and afterbody of the sunk screw 5 are connected with the piston cap 21, pass through countersunk head
Piston magnet 4 is fixedly connected by screw 5 with piston cap 21, simple in construction, is connected firmly.
It is highly preferred that originally new also scrape brushing piece including two panels, the two panels scrapes brushing piece and is divided into the grasping part both sides
On holder body 1, scrape brushing piece can be with moving on 1 online rail of holder body, and then the dust on scraping line rail, reaches the mesh of cleaning
, avoid line rail laying dust from getting rusty, extended line rail service life.
