Description
Technical field
The present invention relates to engine sand core manufacturing field more particularly to a kind of engine tube gas sealing mechanisms.
Background technique
At present when manufacturing engine sand core, need to detect the air-tightness of engine, it is therefore desirable to engine
Pipe carries out closure sealing, at present when being sealed to engine tube, is usually carried out by way of manually installed plugging block
The reason of sealing, but since the working time increases when due to manual operation, personnel's energy consumes, to the installation number of plugging block
And installation site is increasingly easy to appear problem, and using plugging block to engine tube blocked the purpose is to reduce do not conform to
The outflow of lattice product, but artificial block is easy to appear the case where blocking loosely, causes to judge by accident.Therefore, artificial installation envelope is solved
Sprue be easy to appear installation fault the problem of be just particularly important.
Summary of the invention
To solve the above problems, passing through fixed cylinder band it is an object of the invention to provide a kind of engine tube gas sealing mechanism
Dynamic fixing clamp is fixed engine tube, and drives plugging block to carry out automatic plugging to engine tube by blocking cylinder,
It improves work efficiency and operating accuracy, solves the problems, such as that artificially installing plugging block is easy to appear installation fault.
The present invention provides a kind of engine tube gas sealing mechanism, including bottom plate, and placement block is provided on the bottom plate, described
Offer through-hole on bottom plate, the bottom base plate is provided with fixed cylinder, and bottom plate upper end is provided with fixing seat, in the fixing seat
It is provided with fixing clamp, the telescopic rod of the fixed cylinder passes through one end that through-hole is connected to fixing clamp, sets on the bottom plate
It is equipped with closure cylinder, the closure cylinder is mounted on bottom plate by blocking seat, and the closure cylinder front end is provided with plugging block,
Plugging block is driven to block engine tube by blocking cylinder.
Further improvement lies in that: it is provided with stringer board on the bottom plate, is again provided on the stringer board and blocks cylinder, blocks
Seat and plugging block.
Further improvement lies in that: it is provided with mounting hole on the closure seat, blocks cylinder and is fixed by cooperating with mounting hole
On blocking seat, by removing and installing the screw of hole cooperation, and then replaces and block cylinder.
Further improvement lies in that: force sensor is provided between closure cylinder and the plugging block.
Beneficial effects of the present invention: it drives fixing clamp that engine tube is fixed by fixed cylinder, and passes through envelope
Gas shutoff cylinder drives plugging block to carry out automatic plugging to engine tube, improves work efficiency and operating accuracy, avoids the occurrence of closure
Unstable situation occurs, and blocks cylinder by replacement, carries out closure work to the engine tube of different size.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Wherein: 1- bottom plate, 2- place block, 3- through-hole, the fixed cylinder of 4-, 5- fixing seat, 6- fixing clamp, 7- closure gas
Cylinder, 8- block seat, 9- plugging block, 10- stringer board, 11- mounting hole.
Specific embodiment
In order to deepen the understanding of the present invention, the present invention will be described in further detail with reference to the examples below, the embodiment
For explaining only the invention, it is not intended to limit the scope of the present invention..
As shown in Figure 1, the present embodiment provides a kind of engine tube gas sealing mechanism, including bottom plate 1, set on the bottom plate 1
It is equipped with and places block 2, through-hole 3 is offered on the bottom plate 1,1 bottom of bottom plate is provided with fixed cylinder 4, the setting of 1 upper end of bottom plate
There is fixing seat 5, fixing clamp 6 is provided in the fixing seat 5, the telescopic rod of the fixed cylinder 4 passes through through-hole 3 and is connected to admittedly
Determine one end of clip 6, be provided on the bottom plate 1 and block cylinder 7, the closure cylinder 7 is mounted on bottom plate 1 by blocking seat 8
On, 7 front end of closure cylinder is provided with plugging block 9, drives plugging block 9 to block engine tube by blocking cylinder 7.
It is provided with stringer board 10 on the bottom plate 1, is again provided on the stringer board 10 and blocks cylinder 7, blocks seat 8 and plugging block 9.It is described
Block and be provided with mounting hole 11 on seat 8, block cylinder 7 and blocked on seat 8 by being fixed on the cooperation of mounting hole 11, by disassembly with
The screw that mounting hole 11 cooperates, and then replace and block cylinder 8.Stress sensing is provided between the closure cylinder 7 and plugging block 9
Device 11.It drives fixing clamp 6 that engine tube is fixed by fixed cylinder 4, and drives plugging block 9 by blocking cylinder 7
Automatic plugging is carried out to engine tube, is improved work efficiency and operating accuracy, is avoided the occurrence of and is blocked unstable situation and occur,
And cylinder 7 is blocked by replacement, closure work is carried out to the engine tube of different size.
