Description

Technical Field

[0001] The invention belongs to the technical field of electrical switch metal fittings processing, and in particular relates to an electrical switch metal fittings processing device and a processing method thereof. Background Art

[0002] When producing electrical switches, it is necessary to perform silver contact riveting on the metal conductive plates inside them to increase the contact effect and performance of the metal conductive plates. The common silver contact riveting machines on the market are divided into automatic and semi-automatic silver contact riveting machines. Since the purchase price of automatic silver contact riveting machines is much higher than that of semi-automatic silver contact riveting machines, most small electrical switch processing factories choose to use semi-automatic silver contact riveting machines. Traditional semi-automatic silver contact riveting machines require workers to manually stabilize the metal conductive plates when working. Therefore, during riveting, workers' hands are prone to trembling, causing the sheet metal to shake, which in turn causes the rivet nuts to tilt during riveting. In addition, the workers' hands are close to the metal conductive plates, which poses a safety hazard of being pressed. For this reason, we propose a metal accessories processing device for electrical switches and a processing method thereof. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an electrical switch metal accessories processing device and a processing method thereof, which effectively solves the problem that the traditional semi-automatic silver contact riveting machine needs workers to manually stabilize the metal conductive plate when working. Therefore, during riveting, the worker's hand trembles easily, causing the sheet metal to shake, which in turn causes the rivet nut to tilt during riveting, and the worker's hand is close to the metal conductive plate, causing a safety hazard of the worker's hand being pressed.

[0007] Preferably, the vibration plate feeder is arranged on the top left side of the workbench, and the first support frame is arranged on the top right side of the workbench.

[0008] Preferably, the stabilizing assembly includes a first mounting block and a second mounting block, a first sliding groove is provided at the bottom of the first mounting block, a first spring is arranged in the first sliding groove, a pressure rod is provided at the bottom of the first spring, an anti-slip pad is provided at the bottom of the pressure rod, a storage groove is provided at the top of the second mounting block, a second sliding groove is evenly provided at the bottom of the storage groove, a second spring is arranged in the second sliding groove, a guide column is provided at the top of the second spring, a support plate is provided at the top of the guide column, and the elastic force of the first spring is greater than the elastic force of the second spring.

[0009] Preferably, the first mounting block is arranged on the front side of the telescopic end of the second hydraulic rod, the second mounting block is arranged on the front side of the supporting block, and the anti-slip pad is located above the supporting plate.

[0010] Preferably, a conductive plate is placed on the top of the support plate, a silver contact is placed in the riveting groove of the support block, and the top of the silver contact is inserted into the docking hole of the conductive plate.

[0011] Preferably, the top of the second mounting block is flush with the top of the supporting block, and the top of the supporting plate is located above the top of the second mounting block.

[0012] Preferably, the riveting head corresponds to the silver contact located in the riveting groove of the support block, and the bottom horizontal plane height of the anti-slip pad is lower than the bottom horizontal plane height of the riveting head.

[0013] A processing method for a metal fittings processing device for an electrical switch:

[0014] Step 1: Use the vibration plate feeder to input the silver contact into the positioning groove of the push plate along the avoidance groove of the guide frame and the guide plate, and push the push plate forward through the telescopic gas rod. When the positioning groove of the push plate is aligned with the riveting groove of the support block, the silver contact will fall into the riveting groove by its own gravity, and then the telescopic gas rod will drive the push plate to move backward and reset. As the vibration plate feeder works, the next silver contact will continue to be pushed into the positioning groove of the push plate.

[0015] Step 2: The worker places the conductive plate on the support plate, and inserts the top of the silver contact into the docking hole of the conductive plate. Then the second hydraulic rod drives the rivet head and the first mounting block to move downward. Since the bottom horizontal plane height of the anti-slip pad is lower than the bottom horizontal plane height of the rivet head, the anti-slip pad will first contact the conductive plate, and squeeze the conductive plate downward, and squeeze the support plate down into the storage groove of the second mounting block. As the support plate moves downward, the second spring will be squeezed through the guide column. At this time, the anti-slip pad presses the conductive plate down and fixes it on the second mounting block, the support plate and the top of the support block, so as to ensure the stability of the conductive plate when it is riveted later. When the telescopic end of the second hydraulic rod continues to move downward, the pressure rod will squeeze the first spring upward. At this time, as the telescopic end of the second hydraulic rod continues to move downward, it can drive the rivet head to press the silver contact, so that the silver contact completes the riveting work in the docking hole of the conductive plate.

[0016] Step 3: After the riveting is completed, the second hydraulic rod drives the riveting head and the first mounting block to move upward and reset. When the anti-slip pad is separated from the conductive plate, the second spring uses its own resilience to drive the support plate to move upward and reset through the guide column. The support plate drives the conductive plate on its top to move upward, thereby driving the silver contacts fixed in the docking holes of the conductive plate to move upward and loosen the riveting holes of the support block, so that it is convenient for workers to remove the riveted silver contacts and conductive plates.

[0017] Step 4: The first hydraulic rod drives the connecting column and the connecting plate to move downward, thereby driving the supporting feet to move downward to lift the device. At this time, the worker drives the screw rod downward by turning the hand wheel, and drives the base to move downward and fit the ground through the screw rod. Then the first hydraulic rod drives the connecting plate and the supporting feet to reset through the connecting column, so that the workers can freely adjust the height of the device according to their actual needs.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The anti-skid pad first contacts the conductive plate, which can be pressed downward, and the pressing support plate can be moved down into the storage slot of the second mounting block. At this time, the anti-skid pad presses the conductive plate down and fixes it on the second mounting block, the support plate and the top of the support block, so as to ensure the stability of the conductive plate when it is riveted later. At the same time, during the riveting process, the worker does not need to hold the conductive plate by hand, so as to ensure the safety of the worker's hands;

[0020] 2. After the riveting is completed, the second spring uses its own resilience to drive the support plate to move upward and reset through the guide column, and drives the conductive plate on its top to move upward through the support plate, thereby driving the silver contact fixed in the docking hole of the conductive plate to move upward and loosen the riveting hole of the support block, so that it is convenient for workers to remove the riveted silver contact and conductive plate;

[0021] 3. The first hydraulic rod drives the supporting foot to move downward to lift the device. At this time, the worker drives the screw rod downward by turning the hand wheel, and drives the base to move downward and fit the ground through the screw rod. In this way, the worker can freely adjust the height of the device according to his actual needs. BRIEF DESCRIPTION OF THE DRAWINGS

A first sliding groove is provided at the bottom of the first mounting block 3, a first spring 31 is fixedly arranged in the first sliding groove, a pressure rod 32 is fixedly arranged at the bottom of the first spring 31, an anti-slip pad 33 is fixedly arranged at the bottom of the pressure rod 32, a receiving groove is provided at the top of the second mounting block 34, a second sliding groove is evenly provided at the bottom of the receiving groove, a second spring 36 is fixedly arranged in the second sliding groove, a guide column 37 is fixedly arranged on the top of the second spring 36, a support plate 35 is fixedly arranged on the top of the guide column 37, and the elastic force of the first spring 31 is greater than the elastic force of the second spring 36.

[0042] A processing method for a metal fittings processing device for an electrical switch:

[0043] Step 1: The silver contact 4 is input into the positioning groove of the push plate 27 along the avoidance groove of the guide frame 21 and the guide plate 26 through the vibration plate feeder 2, and the push plate 27 is pushed forward by the telescopic gas rod 28. When the positioning groove of the push plate 27 is aligned with the riveting groove of the support block 29, the silver contact 4 will fall into the riveting groove by its own gravity, and then the telescopic gas rod 28 drives the push plate 27 to move backward and reset. As the vibration plate feeder 2 works, the next silver contact 4 continues to be pushed into the positioning groove of the push plate 27.

[0044] Step 2: The worker places the conductive plate 41 on the support plate 35, and inserts the top end of the silver contact 4 into the docking hole of the conductive plate 41. Then the second hydraulic rod 24 drives the riveting head 25 and the first mounting block 3 to move downward.

When the telescopic end of the second hydraulic rod 24 continues to move downward, the pressure rod 32 will press the first spring 31 upward. At this time, as the telescopic end of the second hydraulic rod 24 continues to move downward, it can drive the riveting head 25 to press the silver contact 4, so that the silver contact 4 completes the riveting work in the docking hole of the conductive plate 41.

[0045] Step three: After the riveting is completed, the second hydraulic rod 24 drives the riveting head 25 and the first mounting block 3 to move upward and reset.

The support plate 35 drives the conductive plate 41 on its top to move upward, thereby driving the silver contact 4 fixed in the docking hole of the conductive plate 41 to move upward and loosen the riveting hole of the support block 29, so as to facilitate workers to remove the riveted silver contact 4 and conductive plate 41.
