Description
Technical field
The present invention relates to a kind of assembly machine, specifically be a kind of assembly machine for mechanical seal of rubber bellows.
Background technology
At present, rubber bellows mechanical seal is widely used in fields such as pump class, compressor, refrigeration machine.Its general structure as shown in Figure 1, comprise rotating ring friction pair 1, elastic support 4, spring 5, go up metal tight loop 3 and following metal tight loop 6, the lower end of described rotating ring friction pair 1 is installed in the centre bore of elastic support 4, and be provided with the magnitude of interference between the upper end of elastic support 4 centre bores and the rotating ring friction pair 1, also be provided with the magnitude of interference between the lower end of elastic support 4 centre bores and the turning cylinder.Described upper and lower two metal tight loops all tightly are enclosed within on the elastic support 4; Described upper and lower two metal tight loops closely cooperate elastic support centre bore and rotating ring friction pair 1, turning cylinder; Described spring 5 is enclosed within on upper and lower two metal tight loops, for this mechanical seal provides axial elastic force.
The rubber bellows mechanical seal of the said structure type of prior art all adopts artificial assembling, shown in Fig. 2 a-2d, because the characteristics of its structure, each part assembly sequency also just has been fixed up: the first step, earlier the two ends of upper and lower two metal tight loop loading spring centre bores, be set on the elastic support together then, and the base abuts that makes down the metal tight loop is on the second step face of elastic support; Second step, by external tool, firmly depress the metal tight loop, make the upper end of elastic support stretch out the metal tight loop fully; In the 3rd step, the elastic support centre bore is put in rotating ring friction pair bottom; The 4th step firmly made the metal tight loop up carry, and leant up to metal tight loop upper surface and elastic support first step face.
In the above-mentioned steps of the artificial assembling of rubber bellows mechanical seal, second step and the 4th step are committed steps, it also is the most difficult dress part of whole rubber bellows mechanical seal, the rubber bellows mechanical seal of the prior art brings many inconvenience to operating personnel when assembling, mainly have following shortcoming:
1, in second step, along with the increase of mechanical seal diameter of axle specification, the spring specification and the elastic force that are enclosed within on the elastic support also increase thereupon; Thereby when the assembler depressed the metal tight loop with finger, the strength that need cost a lot of money made relatively difficulty of installation.
2, in the 4th step, the assembler firmly upwards promotes when going up the metal tight loop, and finger firmly size is wanted suitably and evenly; Otherwise tilt phenomenon can appear in the rotating ring friction pair after the installation, and so not only the technology to the assembler has certain requirement, and assembly precision is low; Along with the increase of mechanical seal diameter of axle specification, the power of corresponding lifting metal tight loop also increases thereupon.So, not only make the assembler expend very big strength when the assembling rubber bellows mechanical seal, efficiency of assembling is low, is unfavorable for the assembling in enormous quantities of rubber bellows mechanical seal.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the defective of above prior art, provides a kind of assembling simple, convenient, assembly precision height, efficiency of assembling height, the assembly machine for mechanical seal of rubber bellows that can assemble in enormous quantities.
Technical solution of the present invention is that a kind of assembly machine for mechanical seal of rubber bellows with following structure is provided:
It comprises working panel and indenter device, fixed installation one can be placed the location mandril of rubber bellows mechanical seal on the described working panel, described indenter device is positioned at the top of location mandril, and the axis of location mandril and the central lines of the pressure head in the indenter device also are provided with the clamping cylinder that indenter device is vertically moved on the frame of described indenter device below; A straight runner that is centered close on the location mandril axis also is set on the described working panel, is sliding combined with the clamping device of location mandril in the described straight runner, two jig arm of described clamping device are symmetricly set in the straight runner of location mandril both sides; A jig arm of described clamping device comprises a fixed block that is fixed on the straight runner outer end, the inboard of described fixed block connects a linkage, the free end of described linkage connects a slide block, the inboard of described slide block connects a spacing block, and the madial wall of described spacing block is provided with the spacing block cutting edge; On the frame of described working panel below a draft cylinder is set also, the piston rod of described draft cylinder is connected with two jig arm of clamping device.
After adopting above structure, assembly machine for mechanical seal of rubber bellows of the present invention compared with prior art, have the following advantages: when assembly machine for mechanical seal of rubber bellows assembles, clamping cylinder drives indenter device and moves down, pressure head in the indenter device is depressed the last metal tight loop that is enclosed within on the elastic support, make and be enclosed within, spring compression on the following metal tight loop, thereby make the upper end of elastic support stretch out the metal tight loop fully, draft cylinder drives clamping device and clamps the rubber bellows mechanical seal that is placed on the location mandril then, and the spacing block cutting edge in the clamping device will go up metal tight loop and spring top portion from, the metal tight loop is against on the spacing block, and then put into the rotating ring friction pair, need not come holddown spring like this by other special tool(s)s, therefore it is very convenient to put the rotating ring friction pair, makes assembling simple.Rotating ring friction pair after putting into is utilizing external equipment evenly to depress the rotating ring friction pair, makes the top of metal tight loop be adjacent to the first step face of elastic support.Tilting can not appear in the rotating ring friction pair after the installation like this, and assembly precision height, efficiency of assembling height, assembling can be mass-produced.
As a kind of improvement, an adjustable column also is set on the described working panel, the height of described adjustable column is a little more than the height of spacing block.Described adjustable column can prevent that indenter device from pressing spacing block, thus the damage indenter device.
As a kind of improvement, the sidewall of described spacing block is provided with dovetail groove, and described slide block is provided with the dovetail tangs of the clamping that matches with dovetail groove.Spacing block and slide block be movably connected in the spacing block of changing different size the time convenient.
