Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, specifically to a cutting device for capacitor processing. Background Technology

[0002] A capacitor is a component that stores electrical charge and electrical energy (potential energy). A conductor surrounded by another conductor, or an electric field line emanating from one conductor that terminates entirely in the conductor of another conductor, can be called a capacitor. They are commonly used in circuits for tuning, bypassing, coupling, and filtering.

[0003] As existing technology, the structural processing technology of capacitors is already publicly available. For example, patent application number CN216957776U proposes "a cutting device for capacitor processing, including a mounting base and a drive base. The right side of the mounting base is fixedly connected to the drive base. A fixing plate is fixedly connected to the bottom right side of the drive base. Connecting bolts are symmetrically arranged through the fixing plate. A lifting base is provided on the top side of the drive base. A movable base is movably connected to the right side of the lifting base. A placement base is movably embedded on the top of the drive base." After implementation, "by setting a first motor and a first threaded rod, after processing, the placement base can be pulled out from the top side of the drive base, avoiding the distance between the operator's hand and the cutting head during material handling or loading, thus improving safety before and after processing; 2. by setting a rodless cylinder, a second motor, and a second threaded rod, processing operations can be easily performed, and the height can be adjusted according to the height of the capacitor fixed inside the placement slot, greatly expanding the applicability. Multiple capacitor ends can be milled at once without repeated disassembly and assembly of capacitors, greatly improving work efficiency."

[0004] In reality, during the machining of capacitor housings, components will move due to stress. To ensure machining quality and the stability of components during machining, corresponding limiting structures are required. However, the existing technology does not take this into account. Secondly, machining inevitably produces debris, which will fall directly onto the tooling on which the capacitor housing is placed. This debris needs to be cleaned up in time to avoid adverse effects. The existing technology still does not take this into account. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a cutting device for capacitor processing, which solves the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a cutting device for capacitor processing, including a CNC machining center, a spindle installed inside the CNC machining center, and a machine tool platform. The bottom of the spindle is connected to a machining tool, and the top surface of the machine tool platform is equipped with an I-shaped fixture. The top of the I-shaped fixture is provided with a T-shaped feeding hole for placing a capacitor housing. An electromagnetic chuck for magnetically limiting the capacitor housing is engaged with the inner side of the bottom of the T-shaped feeding hole.

[0007] The I-shaped fixture internally houses a folding airbag and a transition transmission component. The bottom of the transition transmission component is connected to the top of the folding airbag, and the top structure of the transition transmission component is connected to an electromagnetic chuck. A pump assembly is installed on one side of the I-shaped fixture, and the output structure of the pump assembly is connected to the folding airbag via a connecting pipe.

[0008] The preferred transition transmission component mainly consists of a linkage disc and a top rod fixedly connected to the top of the linkage disc. The top of the top rod is fixedly connected to the bottom of the electromagnetic chuck housing, so that the electromagnetic chuck obtains stable support for reciprocating up and down within the T-shaped feeding hole.

[0009] Preferably, the number of T-shaped feeding holes and electromagnetic chucks is the same and not less than two, and the number of top rods is the same as the number of electromagnetic chucks.

[0010] Specifically, the bottom surface of the linkage plate and the top surface of the folding airbag are bonded together with double-sided adhesive, and the bottom of the folding airbag is bonded to the inner wall of the bottom of the I-shaped tooling with double-sided adhesive.

[0011] Preferably, the air pump assembly includes an air pump, a protective box, a filter screen nested in the inner wall of the front end of the air pump, and a switch mounted on the front end surface of the air pump, with the air pump housed inside the protective box.

[0012] In this preferred embodiment, the output end of the air pump serves as the output structure of the air pump assembly, penetrating one side wall of the air pump and connecting to one end of a connecting pipe, while the other end of the connecting pipe is fixedly sleeved on the inner side of the bottom of the folded airbag.

[0013] The top surface of the I-shaped fixture is connected to an arc-shaped cleaning tube, and both ends of the arc-shaped cleaning tube are closed structures. A connecting valve tube is connected between the middle of the arc-shaped cleaning tube and the top of the folded airbag. Several clearance holes facing the top surface of the arc-shaped cleaning tube are opened on the surface of the arc-shaped cleaning tube.

[0014] The top surface of the I-shaped tooling is provided with several guide grooves, and there is a clearance between the guide grooves and the T-shaped discharge hole.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model uses an I-shaped tooling, a T-shaped feeding hole, and an electromagnetic chuck to form a tooling for receiving and processing capacitor housings. It is convenient to install and has a magnetic attraction and limiting effect, ensuring the stability of the capacitor housings during subsequent processing by the spindle and cutting tools in the CNC machining center.

[0017] 2. The pumping assembly of this utility model supplies air to the folded airbag through the connecting pipe, causing it to expand and deform, and then press against the transition transmission component associated with the electromagnetic chuck to perform material lifting treatment on the processed capacitor shell, making it convenient for workers to pick up the material.

[0018] 3. The connecting valve pipe and the arc-shaped cleaning pipe set in this utility model form the reset and exhaust structure of the folding airbag. During the process of retracting and resetting the folding airbag to exhaust air, the arc-shaped cleaning pipe guides the airflow to the top surface of the I-shaped tool for airflow cleaning, thus serving two purposes in one.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5A cutting device for capacitor processing includes a CNC machining center 1, a spindle 2 installed inside the CNC machining center 1, and a machine tool platform 3. The bottom of the spindle 2 is connected to a machining tool. An I-shaped fixture 4 is installed on the top surface of the machine tool platform 3. The top of the I-shaped fixture 4 is provided with a T-shaped feeding hole 5 for placing capacitor housings. An electromagnetic chuck 6 for magnetically limiting the capacitor housings is engaged with the inner side of the bottom of the T-shaped feeding hole 5.

[0027] The internal assembly of the I-shaped fixture 4 includes a folding airbag 7 and a transition transmission component 8. The bottom of the transition transmission component 8 is connected to the top of the folding airbag 7, and the top structure of the transition transmission component 8 is connected to the electromagnetic chuck 6. The transition transmission component 8 mainly consists of a linkage plate and a top rod fixedly connected to the top of the linkage plate. The top of the top rod is fixedly connected to the bottom of the electromagnetic chuck 6 housing, so that the electromagnetic chuck 6 obtains stable support for reciprocating up and down within the T-shaped discharge hole 5. The transition transmission component 8 serves as a power extension structure after the folding airbag 7 expands and deforms, providing working conditions for the automatic discharge of the capacitor housing after the electromagnetic chuck 6 presses and cuts it.

[0028] To meet the requirements of simultaneous processing of multiple capacitor housings, the number of T-shaped feeding holes 5 and electromagnetic chucks 6 is the same and not less than two, and the number of push rods is the same as the number of electromagnetic chucks 6.

[0029] To facilitate the installation of the structure and subsequent disassembly and maintenance, the bottom surface of the linkage plate and the top surface of the folding airbag 7 are glued together with double-sided tape, and the bottom of the folding airbag 7 is glued to the inner wall of the bottom of the I-shaped tool 4 with double-sided tape.

[0030] A pump assembly 9 is installed on one side of the I-shaped fixture 4. The output structure of the pump assembly 9 is connected to the folded airbag 7 through a connecting pipe. The pump assembly 9 includes an air pump 91, a protective box 92, a filter screen nested in the inner wall of the front end of the air pump 91, and a switch installed on the front surface of the air pump 91. The air pump 91 is fitted inside the protective box 92. The output end of the air pump 91, as the output structure of the pump assembly 9, passes through one side wall of the air pump 91 and is connected to one end of the connecting pipe. The other end of the connecting pipe is fixedly sleeved on the inner side of the bottom of the folded airbag 7. The pump assembly 9 provides power for the pneumatic deformation of the folded airbag 7, thereby improving the automated use performance of the overall device.

[0031] The top surface of the I-shaped fixture 4 is connected to an arc-shaped cleaning pipe 11, and both ends of the arc-shaped cleaning pipe 11 are closed structures. The middle part of the arc-shaped cleaning pipe 11 is connected to the top of the folded airbag 7 by a connecting valve pipe 10. The surface of the arc-shaped cleaning pipe 11 has several clearance holes facing the top surface of the I-shaped fixture 4. The top surface of the I-shaped fixture 4 has several guide grooves, and there is a clearance gap between the guide grooves and the T-shaped discharge hole 5. The arc-shaped cleaning pipe 11 and the connecting valve pipe 10 are used together to allow the folded airbag 7 to be vented, retracted, and reset for easy reuse, while using the air discharged from the folded airbag 7 to clean the cutting waste scattered on the top surface of the I-shaped fixture 4 with air.

[0032] Working principle:

[0033] Example 1

[0034] Multiple capacitor housings to be processed are placed inside multiple T-shaped feeding holes 5. Then, the electromagnetic chucks 6 inside the multiple T-shaped feeding holes 5 are activated. The electromagnetic chucks 6 magnetically attract and limit the corresponding capacitor housings. Then, the CNC machining center 1 is turned on, and the top of the multiple capacitor housings to be processed is uniformly cut using the spindle 2 and the cutting tool connected to the spindle 2.

[0035] After the cutting process is completed, multiple electromagnetic chucks 6 are turned off, and staff can conveniently collect the multiple processed capacitor shells.

[0036] Example 2

[0037] Multiple capacitor housings to be processed are placed inside multiple T-shaped feeding holes 5. Then, the electromagnetic chucks 6 inside the multiple T-shaped feeding holes 5 are activated. The electromagnetic chucks 6 magnetically attract and limit the corresponding capacitor housings. Then, the CNC machining center 1 is turned on, and the top of the multiple capacitor housings to be processed is uniformly cut using the spindle 2 and the cutting tool connected to the spindle 2.

[0038] After the cutting process is completed, the air pump 91 inside the air pump assembly 9 is started. Then, air is supplied from the output end of the air pump 91 to the interior of the folding airbag 7 through the connecting pipe, which inflates the folding airbag 7 and presses against the transition transmission component 8 and multiple electromagnetic chucks 6.

[0039] Next, the valve inside the connecting valve pipe 10 is opened, and the airflow discharged from the retracted and reset folded airbag 7 is transported through the pipe body of the connecting valve pipe 10 to the inside of the arc-shaped cleaning pipe 11, and then the top surface of the CNC machining center 1 is cleaned by air blowing through several clearance holes.

[0040] Then, the air pump 91 inside the air pump assembly 9 is restarted, and air is then supplied to the interior of the folding airbag 7 through the connecting pipe from the output end of the air pump 91. This causes the folding airbag 7 to expand and press against the transition transmission component 8 and multiple electromagnetic chucks 6 to perform the material lifting process. Then, the multiple electromagnetic chucks 6 are turned off, and the capacitor shell can be easily retrieved.
