Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure: suppress the ingredient that frame mechanism belongs to the housing air tightness detection equipment among the embodiment, it is used to compress sealing workpiece housing.
Like Fig. 1, shown in Figure 2; This suppresses frame mechanism and mainly is made up of mount pad 1, bearing plate 2, orienting lug 3, Strut Part 4 and baffle plate 9; The transversal section of orienting lug 3 is L-shaped, and orienting lug 3 utilizes the left and right sides of screw retention in mount pad 1 bottom, and two orienting lugs 3 are symmetrical set; Bearing plate 2 is contained between two orienting lugs 3 and through orienting lug 3 and compresses, and between bearing plate 2 and the mount pad 1 cushion block 6 is housed; Utilize screw retention that baffle plate 9 is arranged on the back side edge of mount pad 1, the rear side of bearing plate 2 is spacing through baffle plate 9; The front end of every orienting lug 3 utilizes screw that pad 10 is installed, and the front side of bearing plate 2 is spacing through pad 10; The Strut Part 4 that is used to compress sealing workpiece housing is installed in the bottom of bearing plate 2.The frame mechanism of suppressing among the embodiment is provided with four Strut Parts 4 altogether, and one of them Strut Part 4 is provided with and is used for the valve 11 in the workpiece housing, inflated.
As shown in Figure 1; Said Strut Part 4 mainly is made up of depression bar 4a, pressure head 4d, shaft block ring 4f, compression spring 4c and setting nut 4b; Depression bar 4a utilizes screw retention in bearing plate 2 bottoms; Pressure head 4d center has through hole, and pressure head 4d is enclosed within depression bar 4a and upward and with depression bar 4a is slidingly matched, and the shaft block ring 4f that pressure head 4d is equipped with through depression bar 4a end is spacing; Compression spring 4c is sleeved on the guide rod 7, and compression spring 4c lower end is connected with the upper end of pressure head 4d, is used for exerting pressure to pressure head 4d; The upper end of compression spring 4c is connected on the setting nut 4b, and setting nut 4b spiral shell is contained on the depression bar 4a, and setting nut 4b can be used for regulating the decrement of compression spring 4c, thus the size of the sealing load that control pressure head 4d produces; Said valve 11 is arranged on the pressure head 4d.In order to prevent that introduced contaminants from getting between pressure head 4d and the depression bar 4a, influence the sliding capability of pressure head 4d, the present invention is provided with O-ring seal 4e between pressure head 4d and depression bar 4a, and what sealing circle 4e was assemblied in that pressure head 4d through-hole wall is provided with one encloses in the seal groove.Because pressure head 4d is processed by metal material, it directly is pressed on the workpiece housing may damage the workpiece housing, and it is also bad to compress effect simultaneously, and in order to overcome above-mentioned defective, the present invention adopts super glue to be bonded with gasket seal 4g on pressure head 4d basal surface.Gasket seal 4g one can protect the workpiece housing, and two can strengthen friction force, robust more when the workpiece housing is compressed.
Like Fig. 1, shown in Figure 2; Workpiece housing for routine; Usually there is the situation that the seal point position is asymmetric and sealing load varies in size; For the associated components that prevents to suppress in frame mechanism and the checkout equipment receives force unbalance to produce distortion because of causing, the present invention has installed four equilibrium pressure rod members 5 for four jiaos in the bottom of bearing plate 2, and each equilibrium pressure rod member 5 mainly is made up of balance depression bar 5a, balance pressure head 5d and set nut 5b; Balance depression bar 5a utilizes screw retention in bearing plate 2 bottoms, and balance pressure head 5d is threaded on the balance depression bar 5a and passes through the spacing locking of set nut 5b.Four above-mentioned equilibrium pressure rod member 5 symmetric arrangement help improving the rigidity and the stability of suppressing frame mechanism, guarantee each seal point positiver sealing simultaneously.
As shown in Figure 1, the top of said mount pad 1 utilizes screw retention that guide rod 7 is arranged, guide rod 7 be used for checkout equipment steel member upper frame on the guide pin bushing (not shown) that is provided be slidingly matched.
During concrete the application; Guide rod 7 is contained in the guide pin bushing on the checkout equipment steel member upper frame, starts upper cylinder 8 (see figure 1)s, under the guiding of guide rod 7; The piston rod of upper cylinder 8 promotes mount pad 1, and mount pad 1 is with bearing plate 2 and Strut Part 4 downward easy motions mounted thereto.The pressure head 4d correspondence of Strut Part 4 compresses and seals up all through holes on the workpiece housing.
Suppress bearing plate 2 or the pressure head 4d in the Strut Part 4 in the frame mechanism through replacing, promptly the impermeability applicable to the different workpiece housing detects.
