Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic capacitor clamping, in particular to a clamping tool based on an electrolytic capacitor. Background Art

[0002] Electrolytic capacitors refer to capacitors that use anodization to generate a thin layer of oxide as a dielectric on the surface of valve metals such as aluminum, tantalum, niobium, and titanium, and use electrolyte as the cathode. The anode of an electrolytic capacitor usually adopts a corroded foil or a powder sintered block structure. Its main feature is that the capacity per unit area is very high. It has an unparalleled advantage over other types of capacitors in terms of small size and large capacity. The production of a capacitor requires automatic hose application, automatic aging, automatic testing, automatic taping, automatic lead wire forming and cutting, and each process must be transferred to different equipment for testing. Aluminum electrolytic capacitors are mainly made of foil anodes and electrolyte cathodes, and most of them are cylindrical in appearance.

[0003] After searching, the Chinese patent publication number CN209249302U discloses a clamping device for electrolytic capacitors. It includes: a mounting frame, a turntable, and a fixed column. A horizontally placed mounting plate extends from the top of the mounting frame. A motor placed vertically downward is provided at the bottom of the mounting plate. The end of the motor is connected to the turntable through a transmission assembly. The turntable is placed horizontally. There are multiple grabbing mechanisms evenly distributed on the turntable. The grabbing mechanisms include: a first cylinder arranged on the turntable and placed vertically downward, a transition plate, a second cylinder, a fixed column, and a clamping assembly. Since the electrolytic capacitor is light in weight, the compression spring will provide a buffer force when clamping the electrolytic capacitor, so that when a certain range of force is applied, the second clamping piece will not deform the electrolytic capacitor. There are multiple grabbing mechanisms evenly distributed on the turntable, which can realize clamping, temporary storage, and placement at the same time, saving transportation time and speeding up transportation efficiency.

[0004] The above patent has the following defects: the clamping device is only suitable for grasping and clamping electrolytic capacitors. During the production of electrolytic capacitors, it is necessary to perform processing, testing and other work while clamping the electrolytic capacitors. The electrolytic capacitors need to be clamped and positioned on the workbench, but the above clamping assembly cannot provide clamping for the electrolytic capacitors while ensuring the processing performance of the electrolytic capacitors. In view of this, we propose a clamping tool based on electrolytic capacitors. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] See also Figure 1-Figure 5 As shown, a clamping tool based on an electrolytic capacitor includes a workbench 1, a slide groove is provided on the top of the workbench 1, an automatic sensing clamp 2 is slidably connected in the slide groove, a driving disk 3 is slidably connected to the bottom end of the automatic sensing clamp 2, a driving device 4 is provided at the bottom end of the driving disk 3, and a cutting device 5 is provided inside the workbench 1.

[0026] In this embodiment, the automatic sensing clamp 2 includes a clamp seat 21, the bottom of the clamp seat 21 is fixedly connected to a sliding shaft 22, the surfaces of the sliding shaft 22 are respectively slidably connected to the inner walls of the slide groove and the driving disk 3, the surface of the clamp seat 21 is fixedly connected to an elastic air bag 23, the interior of the clamp seat 21 is connected to the interior of the elastic air bag 23 through a connecting cavity 24, and the inner wall of the connecting cavity 24 is slidably connected to a piston rod 25. Through the provision of the elastic airbag 23, when the clamp seat 21 over-squeezes the electrolytic capacitor, the elastic airbag 23 will be deformed in advance, and the deformation force drives the circulation of the internal gas. The air pressure squeezes the piston rod 25 in the connecting cavity 24, and the piston rod 25 is pressed to cut off the device 5 to drive the structure inside the driving device 4 to operate, thereby achieving the effect of the clamp seat 21 no longer moving, thereby avoiding the problem of excessive clamping of the electrolytic capacitor by the clamp seat 21 causing damage to its surface. The clamp seat 21 can automatically sense the electrolytic capacitor and position it in time, and has the effect of positioning and clamping electrolytic capacitors of different sizes, thereby improving the applicability and practicality of the overall workbench 1 for clamping different electrolytic capacitors.

[0027] Furthermore, the driving device 4 includes a mounting plate 41 and a self-locking device 46. The top of the mounting plate 41 is fixedly connected to the bottom of the workbench 1. The surface of the mounting plate 41 is fixedly connected to an electric push rod 42. The output shaft of the electric push rod 42 is connected to a limit seat 43. The limit seat 43 is internally slidably connected to a passive block 44. A rack 45 is fixedly connected to the passive block 44. By starting the electric push rod 42, the output shaft of the electric push rod 42 drives the rack 45 on the passive block 44 to move through the limit seat 43. During the movement, the rack 45 drives the meshing worm wheel 463 on the worm 462 to rotate through the meshing gear 461. The worm wheel 463 drives the driving disk 3 to rotate through the connecting shaft 464. The driving disk 3 drives the sliding shaft 22 that is limited by the sliding groove to move linearly through the four groups of inclined grooves opened thereon. The four groups of sliding shafts 22 move toward the center point of the workbench 1. During the movement, the sliding shaft 22 realizes the positioning and clamping of the electrolytic capacitor through the clamping seat 21.

[0028] Furthermore, the self-locking device 46 includes a gear 461, the surface of which meshes with the surface of the rack 45, a worm 462 is fixedly connected to the inside of the gear 461, a worm wheel 463 is meshed with the surface of the worm 462, and the inside of the worm wheel 463 is fixedly connected to the inside of the driving disk 3 through a connecting shaft 464. The surface of the connecting shaft 464 is rotatably connected to the inside of the workbench 1, and both ends of the worm 462 are rotatably connected to a connecting plate 465, and the top of the connecting plate 465 is fixedly connected to the workbench 1. Through the design of the worm wheel 463 and the worm 462, the clamping seat 21 has a self-locking effect after positioning, which can ensure the stability of the electrolytic capacitor during the clamping period, and the electrolytic capacitor is fixedly positioned on the workbench 1, which can facilitate the processing head to process or test the surface of the electrolytic capacitor.

[0029] See also Figure 1-Figure 5 As shown, a spring is fixedly connected between the top of the limiting seat 43 and the bottom of the rack 45 , and the surface of the passive block 44 is slidably connected to the bottom of the workbench 1 .

[0030] Furthermore, the cutting device 5 includes a magnetic ring 51, the top of the magnetic ring 51 is magnetically connected to the bottom of the driving disk 3, and the bottom end of the magnetic ring 51 is fixedly connected to a pressure plate 52. The two ends of the pressure plate 52 are respectively in contact with the end of the piston rod 25 and the surface of the passive block 44. Through the setting of the magnetic ring 51, the effect of magnetically connecting the pressure plate 52 is achieved. On the one hand, the magnetic connection is breakable. When the force applied to the pressure plate 52 is greater than the magnetic force, the pressure plate 52 can move. On the other hand, the magnetic force can be used to realize the reset movement of the pressure plate 52, which facilitates the repeated and cyclic operation of the pressure plate 52.

[0031] When in use, a clamping fixture based on an electrolytic capacitor of the utility model is arranged by placing an electrolytic capacitor between four clamping seats 21 of a workbench 1, and starting an electric push rod 42. The output shaft of the electric push rod 42 drives a rack 45 on a passive block 44 to move through a limit seat 43. During the movement, the rack 45 drives a worm wheel 463 meshing on a worm 462 to rotate through a meshing gear 461. The worm wheel 463 drives a driving disk 3 to rotate through a connecting shaft 464. The driving disk 3 drives a sliding shaft 22 whose sliding is limited by the sliding groove to move linearly through four groups of inclined grooves provided thereon. The four groups of sliding shafts 22 move toward the center point of the workbench 1. During the movement, the sliding shaft 22 realizes positioning and clamping of the electrolytic capacitor through the clamping seat 21. When the elastic airbag 23 on the clamp seat 21 contacts the surface of the electrolytic capacitor, it first exerts a thrust, which can drive the electrolytic capacitor to position and adjust. When the electrolytic capacitor is located at the center of the workbench 1, if the four clamp seats 21 continue to squeeze the electrolytic capacitor, it will cause excessive squeezing and damage the electrolytic capacitor. At this time, through the setting of the elastic airbag 23, when the clamp seat 21 over-squeezes the electrolytic capacitor, the elastic airbag 23 will be deformed in advance, and the deformation force drives the circulation of internal gas. The air pressure squeezes the piston rod 25 in the connecting cavity 24. The piston rod 25 slides downward after being compressed, and contacts and squeezes the pressure plate 52 during the downward sliding period. The pressure on the pressure plate 52 is greater than the magnetic force. During the downward squeezing period, the passive block 44 is driven to slide downward in the limit seat 43. At this time, the rack 45 moves downward and disengages from the gear 461 after moving downward, and then The effect of cutting off the rotational power of the gear 461 is achieved. The rack 45 can continue to be driven and moved by the limit seat 43, while the gear 461 does not rotate at this time, thereby achieving the effect of the clamp seat 21 no longer moving, thereby avoiding the problem of excessive clamping of the electrolytic capacitor by the clamp seat 21, resulting in damage to its surface. According to the clamping tooling of the present technical solution, the clamp seat 21 can automatically sense the electrolytic capacitor and position it in time, and has the effect of positioning and clamping electrolytic capacitors of different sizes, thereby improving the overall applicability and practicality of the workbench 1 for clamping different electrolytic capacitors. Through the design of the worm gear 463 and the worm 462, the clamp seat 21 has a self-locking effect after positioning, thereby ensuring the stability of the electrolytic capacitor during clamping, and fixing the electrolytic capacitor on the workbench 1, which can facilitate the processing or testing of the surface of the electrolytic capacitor by the processing head.
