Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of mechanical sealing member kludge hold-down mechanism that can reduce mechanical sealing member production cost.

For achieving the above object, the utility model provides following technical scheme: a kind of mechanical sealing member kludge hold-down mechanism, comprise be separately positioned on the upper and lower both sides of rotary table on hold down assembly and under hold down assembly, hold down assembly on described and comprise the upper compression cylinder be all arranged on above rotary table and the upper compact heap be fixed on compression cylinder catch bar, the relative station of described upper compact heap is arranged, hold down assembly under described and comprise the lower compression cylinder be all arranged on below rotary table and the lower compact heap linked with lower compression cylinder catch bar, described lower compact heap is relatively gone up compact heap and is arranged.

By adopting technique scheme, by above hold down assembly and under the setting that holds down assembly, just effectively about one effect simultaneously compressed can be carried out to mechanical sealing member in the compaction process of mechanical sealing member, by upper compression cylinder and the upper compact heap be fixed on upper compression cylinder catch bar, in the process compressed, only need compression cylinder to extend its catch bar, effectively reach one to the effect that mechanical sealing member compresses, by lower compression cylinder and the setting of lower compact heap that links with lower compression cylinder catch bar, lower compression cylinder action is only needed in the process compressed, effectively reach one to the effect compressed under mechanical sealing member, so just effectively can reduce and occur coming loose after assembly working completes the probability that needs do over again at mechanical sealing member, effectively reduce the production cost of mechanical sealing member.

The utility model is set to further: the position that described installing rack goes up compact heap relatively offers a vertical slide opening, described lower compact heap is embedded in slide opening, and its lower end is provided with lozenges, the catch bar of described lower compression cylinder is fixed with wedge, and inclined-plane and the lozenges of described wedge are inconsistent.

By adopting technique scheme, because distance between compact heap and lower compact heap in the process compressed should not be excessively near, if cross near words easily damage mechanical sealing member, and on the stroke that holds down assembly be not easy regulation and control, thus by the setting of wedge and lozenges, when the catch bar of lower compression cylinder stretches, lower compact heap will carry out a small amount of slippage up and down in slide opening, so just effectively can reach one and control the lower problem that there will not be again the mechanical sealing member that between upper-lower compacting block, hypotelorism causes to damage between compact heap and upper compact heap while mating reaction.

Detailed description of the invention

With reference to shown in Fig. 1, a kind of mechanical sealing member kludge hold-down mechanism of the present embodiment, comprise be separately positioned on the upper and lower both sides of rotary table on hold down assembly 1 and under hold down assembly 2.

By adopting technique scheme, when the mechanical sealing member assembled is transported to hold-down mechanism place by rotary table, Fibre Optical Sensor in upper compression cylinder 11 will sense mechanical sealing member, thus compression cylinder 11 action is gone up, extend the upper compact heap 12 of its catch bar promotion to move downward, simultaneously by finding out in accompanying drawing that the lower compression cylinder 21 of the present embodiment is for being horizontally disposed with, the inclined-plane of wedge upward, the inclined-plane of lower compact heap 22 down, thus mechanical sealing member by while compression cylinder 11 senses, lower compression cylinder 21 also senses, lower compression cylinder 21 just can extend its catch bar afterwards, wedge will carry out horizontal movement under the effect of its catch bar, and lower compact heap 22 just cannot carry out horizontal movement due to the restriction of slide opening thereupon, and due to the inclined-plane of lozenges and wedge inconsistent, lower compact heap 22 moves up and down so will carry out one, so just effectively can reach a lower compact heap 22 coordinates upper compact heap 12 to carry out the effect of compression work, simultaneously the stroke up and down of lower compact heap 22 here has the slope on the inclined-plane on lozenges and wedge to determine, so the problem that the mechanical sealing member caused due to the hypotelorism between upper-lower compacting block 22 when just can effectively avoid compressing damages, effectively reduce the production cost of mechanical sealing member.

Below the specific works process of mechanical sealing member kludge of the hold-down mechanism of application the present embodiment and principle are described in further detail

With reference to shown in Fig. 2, in the present embodiment, after the hold-down mechanism of the present embodiment is arranged on the order of the trim ring conveying mechanism on application the present embodiment kludge, so in the process of producing, first by shell conveying mechanism shell to be transported on the station on rotary table that (wherein the structure of shell conveying mechanism is here identical with background technology, it is a vibrating disk, guide rail and manipulator composition, other rubber ring conveying mechanism, graphite circle conveying mechanism is identical equally with it with trim ring conveying mechanism, thus do not repeating), by graphite circle conveying mechanism, graphite circle is transported in the shell on rotary table station afterwards, then rubber ring is transported in the shell on rotary table station by rubber ring conveying mechanism, trim ring is transported in the shell on rotary table station by last trim ring conveying mechanism, by hold-down mechanism, pressuring action is carried out to the mechanical sealing member assembled afterwards, this completes the making of one-time mechanical seal, owing to having carried out pressuring action finally by hold-down mechanism, thus the mechanical sealing member in the end produced just is not easy to occur that parts come loose the rework problems caused, effectively reduce the production cost of mechanical sealing member.

In sum, by above hold down assembly 1 and under hold down assembly 2 setting, just can do one to the mechanical sealing member assembled and compress action, effectively avoid the mechanical sealing member that assembles due to the problem of doing over again caused lax between parts, effectively reduce the production cost of mechanical sealing member.

The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
