Description
The present invention relates to the gap measuring device of spacing between a kind of measurement electron gun electrode, particularly a kind of improved gap measuring device, it can prevent the part distortion that the collision of connector causes.
An electron gun comprises many parts, for example provides the electrode of certain amplitude voltage on grid and its, and the focus characteristics of electron gun depends on to a great extent and places one three control grid and the screen grid on the polar region section.Therefore, the manufacturing process of an electron gun comprises the step of spacing between the screen grid of measuring the control grid.Finish above-mentioned functions traditional gap measuring device structure as shown in Figure 1, wherein plumb post 12 is fixed on the frame 11, has the last connecting rod 13 of counterweight 14 and 18 and lower link 15 to be contained on the pillar 12 respectively.In addition, prone upward contactor 13b is fixed on the front end of connecting rod 13, and connect the carriage 15a of following contactor 15b and the front end that bellows formula displacement transducer 16 is contained in lower link 15, and following contactor 15b is relative with last contactor 13b, and displacement transducer 16 contacts with last connecting rod 13 all the time.
As last contactor 13b and following contactor 15b and control grid G
1With screen grid G
2During contact, the displacement of traditional gap measuring device detecting sensor 16 of Gou Chenging and the data transaction that detects become the control grid G as mentioned above
1With screen grid G
2Between a measured value of spacing.
Yet, in a kind of so traditional gap measuring device, since the bump of last contactor 13b and following contactor 15b, grid G
1And G
2May be out of shape, even reduced grid G by the counterweight 14 and 18 that connecting rod 13 and 15 are provided
1And G
2Collision, but thisly reduce to still have a limit because the movement velocity of connecting rod, the movement velocity that particularly goes up connecting rod 13 is very high.
Therefore, the purpose of this invention is to provide a kind of improved gap measuring device, wherein, owing to the part distortion that the collision of connector causes, the deformation energy of particularly controlling grid and screen is suppressed to greatest extent.
In order to realize this purpose, gap measuring device of the present invention comprises last connecting rod and the lower link with counterweight and connector, wherein, provides a damping device on the last connecting rod, is used to reduce the movement velocity that goes up connecting rod.Damping device comprises that one is used for storing a kind of shell of viscous fluid and in the shell pistons reciprocating.One fluid path is arranged on the piston, viscous liquid can be flow through.
To make purpose of the present invention and other advantage more obvious with reference to the accompanying drawing detailed description of the present invention.
Fig. 1 is the end view of a traditional gap measuring device;
Fig. 2 is the end view of gap measuring device of the present invention;
Fig. 3 is the cutaway view of the damping device that adopts of gap measuring device;
Fig. 4 A and 4B are the detailed section view of Fig. 3 damping device.
As shown in Figure 2, plumb post 12 is fixed on the frame 11, and last connecting rod 13 and lower link 15 conducts with counterweight 14 are pivotally mounted on the pillar 12, and prone upward contactor 13b is fixed on the front end of connecting rod 13.In addition, carriage 15a and bellows formula displacement transducer 16 are installed in the front end of lower link 15, and carriage 15a is connected with the following contactor 15b that faces last contactor 13b, and displacement transducer 16 contacts with last connecting rod 13 all the time.
Simultaneously, as shown in Figure 3, in a side of displacement transducer 16, provide damping device 20, it comprises that one is contained in the shell 23 on the lower link 15, and form in piston rod 21d lower end be fixed on piston 21 on the connecting rod 13, be used in shell 23 reciprocating motions.A hemisphere recess 21C is formed on the bottom at piston 21.Also provide vertical passage 21a and two horizontal pathways 21b on the piston.In addition, be formed with basin shape inclined-plane 22a and through hole 22b in the center of the casing cover 22 that is fixed on shell 23 tops.
In the gap measuring device of the present invention that constitutes as mentioned above, last connecting rod 13 is low speed and gently rotating on pivot owing to the effect of damping device.That is, electron gun structure is inserted between contactor 13b and the following contactor 15b, and as measurement target, counterweight 14 rotates connecting rod 13 lentamente on pivot, and rotates on pivot with constant speed owing to the effect of damping device 20.
Be appreciated that the above-mentioned gentle movement of connecting rod 13 by following description.Shown in Fig. 4 A, when being fixed on piston 21 on the connecting rod 13 by piston rod 21d when advancing in the shell 23, at hemisphere recess 21c, the toughness fluid flows through among vertical passage 21a and the horizontal pathways 21b, and therefore, the pace of piston 21 is lowered.When piston 21 entered in the shell 23, a part of viscous fluid flowed upward to the top of shell 23 by horizontal pathways 21b, caused a part of fluid to be stayed covering at the bottom of 22 the basin shape among the 22a.On the other hand, if piston 21 moves to the top of shell 23 shown in Fig. 4 B, fluid is forced in the suction shell by the space between piston 21 and through hole 22b.
The gap measuring device of the present invention that provides the damping device of working has in a manner described reduced the distortion of grid body to greatest extent.By preventing the grid distortion, can increase the q﹠r of electron gun, can also improve the image quality of cathode ray tube.
