Description

Technical Field

[0001] This application relates to the field of clamping equipment technology, and in particular to a capacitor cover clamping device. Background Technology

[0002] The capacitor cover is an important component of a capacitor. It is located on top of the capacitor and mainly serves to seal, insulate, protect, and connect.

[0003] Existing capacitor covers typically include a cover body, insulating material, terminals, and explosion-proof devices. The terminals and cover body are usually fixed by press-fitting. The terminals are cylindrical, with a positioning tab at one end that abuts against the cover body. During fixing, the terminal passes through one side of the cover body, causing the positioning tab to abut against the cover body. A riveting tab is then fitted over the other end of the terminal, and external force (manual hammering or equipment pressure) is applied to the riveting tab, causing it to press against the cover body.

[0004] Regarding the aforementioned technologies, existing pressing equipment typically only presses the rivet pieces during the stamping process, resulting in a high probability of the cover plate body wobbling. Utility Model Content

[0005] To reduce the probability of movement during cover plate stamping, this application provides a capacitor cover plate clamping device.

[0006] The capacitor cover clamping device provided in this application adopts the following technical solution:

[0007] A capacitor cover plate clamping device includes a worktable, a positioning seat disposed on the worktable for placing the cover plate, and a riveting assembly for riveting. It also includes a clamping assembly for clamping the cover plate. The clamping assembly includes a clamping seat, a clamping plate that is vertically disposed on the clamping seat, and a first lifting drive member that drives the clamping plate to move up and down. The clamping plate and the positioning seat are correspondingly disposed.

[0008] By adopting the above technical solution, the cover plate is positioned on the positioning seat. During riveting, the first lifting drive component is activated to move the clamping plate toward the positioning seat, thereby pressing the cover plate onto the positioning seat. Then, the riveting assembly is activated to press the riveting plate onto the surface of the cover plate, thus fixing the terminal block and the cover plate. The clamping assembly can limit the movement of the cover plate and reduce the probability of the cover plate moving during riveting.

[0009] Optionally, the riveting assembly includes a riveting seat and a clamping rod that is lifted and disposed on the riveting seat and corresponds one-to-one with the wiring terminals. The end face of the clamping rod is provided with a clamping surface, and the clamping rod is provided with a clamping groove coaxial with the wiring terminals.

[0010] By adopting the above technical solution, the structural composition of the riveting assembly is disclosed. During riveting, the terminal post is inserted into the clamping groove, and the clamping surface of the clamping rod clamps the riveting plate. The structure is simple and the riveting effect is good.

[0011] Optionally, the clamping plate has guide holes that penetrate both end faces and allow the clamping rod to pass through.

[0012] By adopting the above technical solution, the guide hole can guide the clamping rod when it moves down for riveting, thus improving the stability of the clamping rod during riveting.

[0013] Optionally, the top surface of the positioning seat is provided with a positioning groove for placing the positioning piece.

[0014] By adopting the above technical solution, the positioning groove facilitates the positioning of the positioning piece in the positioning seat, so that during riveting, the bottom surface of the cover plate and the positioning piece can fit on the positioning seat, improving the stability during riveting and reducing the probability of deformation of the bottom surface of the cover plate.

[0015] Optionally, the positioning seat is provided with a buffer assembly, which includes a buffer telescopic rod disposed between the positioning seat and the worktable and a buffer spring sleeved on the buffer telescopic rod.

[0016] By adopting the above technical solution, the buffer component can buffer the pressure generated during riveting, thus extending the service life of the clamping device.

[0017] Optionally, the clamping plate is detachably mounted on the first lifting drive component, the side wall of the clamping plate is provided with a plug-in portion, the first lifting drive component has a plug-in groove for inserting the plug-in portion, and the clamping side wall is provided with an elastic snap-fit ​​component for fixing with the first lifting drive component.

[0018] By adopting the above technical solution, the clamping plate is installed on the first lifting drive component, which allows the operator to select the appropriate clamping plate according to different cover plate sizes, thereby improving the adaptability of the clamping device. Moreover, the disassembly and assembly structure of the above structure is relatively simple and easy to operate.

[0019] Optionally, the insertion part is provided with a receiving groove for mounting the elastic snap-fit ​​member. The elastic snap-fit ​​member includes a mounting shell, a connecting spring disposed in the mounting shell, and a snap-fit ​​connector disposed at the end of the connecting spring. The inner wall of the insertion groove is provided with a plurality of locking grooves that cooperate with the snap-fit ​​connector along the extension.

[0020] By adopting the above technical solution, the structure of the elastic snap-fit ​​component is disclosed. When the plug is inserted into the plug groove, the snap-fit ​​component retracts into the mounting shell under the pressure of the inner wall of the plug groove. After the snap-fit ​​component and the locking groove are aligned, the snap-fit ​​component springs back to the locking groove under the action of the connecting spring, thereby realizing the connection between the plug and the first lifting drive component.

[0021] Optionally, a locking groove is provided at the top of the plug-in portion, and a locking bolt is provided in the locking groove. The first lifting drive component has a strip-shaped hole along the installation direction of the plug-in portion, and the strip-shaped hole corresponds to the locking groove.

[0022] By adopting the above technical solution, after the plug-in part is pre-fixed, the locking bolt is then passed through the strip hole and the locking groove bolt to achieve a fixed connection between the plug-in part and the first lifting drive component. The strip hole can be adapted to plug-in parts with different locking positions.

[0023] Optionally, the locking groove is connected to the receiving groove, and the insertion part is slidably provided with a push post for pushing the mounting shell at the bottom of the locking groove. The end of the push post is provided with an inclined surface for the locking bolt to abut against.

[0024] By adopting the above technical solution, the receiving groove is connected to the locking groove, and a pusher is provided in the receiving groove to push the mounting shell, so that when the plug-in part and the first lifting drive component are connected, the pusher will press the mounting shell towards the locking groove, compress the connecting spring, and improve the connection strength between the elastic connector and the locking groove.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By setting up the clamping component, this application can limit and clamp the cover plate, reducing the probability of the cover plate moving during riveting;

[0027] 2. By providing a guide hole, this application can guide the riveting of the clamping rod and improve the stability of the clamping rod during riveting.

[0028] 3. In this application, the push column and locking bolt work together to complete the fixed connection between the plug-in part and the first lifting drive component. At the same time, the push column presses the mounting shell towards the locking groove, thereby improving the connection strength between the elastic connector and the locking groove.

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0037] This application discloses a capacitor cover clamping device.

[0038] Reference Figure 1 A capacitor cover plate clamping device includes a worktable 1, a positioning seat 2 disposed on the top of the worktable 1, a riveting assembly 3 disposed on one side of the positioning seat 2, and a clamping assembly 4 for clamping the cover plate.

[0039] Reference Figure 1 and Figure 2 The positioning seat 2 is a rectangular plate used for positioning the cover plate. The top surface of the positioning seat 2 has two spaced positioning grooves 21. The depth of the positioning grooves 21 is matched with the thickness of the positioning piece, so that one end of the positioning piece of the terminal post can be positioned in the positioning groove 21. During riveting, the top surface of the cover plate and the positioning seat 2 are in a close fit, which improves the riveting stability.

[0040] A buffer assembly 5 is provided between the positioning seat 2 and the worktable 1. The buffer assembly 5 includes a buffer telescopic rod 51 and a buffer spring 52 sleeved on the buffer telescopic rod 51. The buffer telescopic rod 51 includes an inner rod and an outer rod. The end of the inner rod is fixed to the bottom surface of the positioning seat 2, and the end of the outer rod is fixed to the worktable 1. The buffer spring 52 is sleeved on the outer rod, and its two ends abut against the bottom surface of the positioning seat 2 and the top surface of the worktable 1, respectively.

[0041] Reference Figure 1 and Figure 3 The clamping assembly 4 includes a clamping seat 41, a clamping plate 42 that is vertically mounted on the clamping seat 41, and a first lifting drive 43 that drives the clamping plate 42 to move vertically. The clamping seat 41 is a rectangular block and is bolted to one side of the worktable 1. The first lifting drive 43 can be a lifting structure capable of lifting in the prior art; in this embodiment, the first lifting drive 43 is a lifting cylinder. The output end of the lifting cylinder is provided with a connecting plate 44, which is fixedly connected to the clamping plate 42. The clamping plate 42 and the positioning seat 2 are arranged correspondingly. During riveting, the top surface of the cover plate is first clamped and limited by the clamping plate 42.

[0042] Reference Figure 3 and Figure 4 The riveting assembly 3 includes a riveting base 31, a clamping rod 32 mounted on the riveting base 31, and a second lifting drive component for driving the clamping rod 32 to move. The second lifting drive component is a hydraulic cylinder. The clamping rod 32 and the positioning groove 21 on the positioning base 2 are correspondingly provided. The end face of the clamping rod 32 forms a clamping surface 321 for fitting the riveting piece, and the end of the clamping rod 32 also has a clamping groove 322. The depth of the clamping groove 322 is adapted to the length of the terminal post so that the clamping surface 321 can fit the riveting piece. The clamping plate 42 has guide holes 421 that penetrate both end faces and correspond one-to-one with the clamping rod 32. The guide holes 421 can improve the stability of the clamping rod 32 during riveting.

[0043] Reference Figure 5 and Figure 6 To improve the compatibility of the clamping plate 42 with cover plates of different sizes, the clamping plate 42 is detachably installed on the connecting plate 44. The guide holes 421 of different clamping plates 42 have different sizes and opening positions, but the connection method with the connecting plate 44 is the same. A plug-in portion 422 is integrally provided on the horizontal sidewall of the clamping plate 42. The sidewall of the connecting plate 44 has a plug-in groove 441 for horizontal insertion of the plug-in portion 422.

[0044] The opposite side walls of the insertion portion 422 are provided with receiving grooves 4221, and elastic snap-fit ​​members 45 for pre-fixing with the connecting plate 44 are installed in the receiving grooves 4221. The elastic snap-fit ​​member 45 includes a mounting shell 451, a connecting spring 452 disposed in the mounting shell 451, and a snap-fit ​​connector 423 disposed at the end of the connecting spring 452. The snap-fit ​​connector 423 is spherical, and in the normal state of the connecting spring 452, the snap-fit ​​connector 423 protrudes from the side wall of the insertion portion 422.

[0045] Multiple locking grooves 442 are evenly spaced along the extension direction on opposite side walls of the insertion slot 441. The locking grooves 442 are used for locking with the snap-fit ​​connector 423. A locking groove 4222 communicating with the receiving groove 4221 is opened in the middle of the top surface of the insertion part 422. The locking groove 4222 is a threaded hole. A locking bolt 4223 is arranged in the locking groove 4222 of the insertion part 422, and the locking bolt 4223 and the locking groove 4222 are threadedly engaged.

[0046] The top of the connecting plate 44 has a strip hole 443 that communicates with the insertion groove 441 along the insertion direction of the insertion part 422. The strip hole 443 corresponds to the locking groove 4222, and the width of the strip hole 443 is smaller than the outer diameter of the bolt head of the locking bolt 4223.

[0047] The insertion part 422 has a push post 46 slidably disposed within the receiving groove 4221. One end of the push post 46 is fixedly connected to the end of the mounting shell 451, and the other end corresponds to the end of the locking groove 4222. The other end of the push post 46 also has an inclined surface 461 for the end of the locking bolt 4223 to abut against. The inclined surface 461 gradually slopes from high to low towards the axis of the locking groove 4222, so that when the locking bolt 4223 is screwed into the locking groove 4222, the screw abuts against the inclined surface 461 to drive the push post 46 to move towards the mounting shell 451, thereby compressing the connecting spring 452 inside the mounting shell 451 and improving the connection strength between the snap-fit ​​connector 423 and the locking groove 442.

[0048] The mounting housing 451 has a limiting part 4511 at the end facing the push post 46. The receiving groove 4221 has a sliding groove 4224 at the end away from the locking groove 4222 for the mounting housing 451 to be arranged. The inner diameter of the sliding groove 4224 is adapted to the outer diameter of the limiting part 4511 so that the mounting housing 451 can only move towards the locking groove 442. A spring for reset is sleeved on the outside of the push post 46 so that the push post 46 and the elastic snap-fit ​​member 45 can be reset simultaneously after the locking bolt 4223 is unscrewed.

[0049] The implementation principle of the capacitor cover plate clamping device in this application embodiment is as follows: First, select a suitable clamping plate 42 according to the size of the cover plate to be riveted. The clamping plate 42 and the connecting plate 44 are fixedly connected by locking bolts 4223. The cover plate is positioned on the positioning seat 2. Then, the first lifting drive 43 is activated so that the clamping plate 42 is pressed and adhered to the top surface of the cover plate. Then, the second lifting drive is activated so that the clamping rod 32 is inserted into the guide hole 421 and into the terminal post. The clamping surface 321 abuts against the rivet plate. Continue to press down so that the rivet plate is inserted with interference and pressed against the top surface of the cover plate.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
