Description

Technical Field

[0001] This utility model belongs to the field of switch moving contact production technology, and specifically relates to a switch moving contact production equipment. Background Technology

[0002] Switch moving contact production equipment is a machine and process system specifically used to manufacture moving contacts (also known as active contacts or moving contacts) in electrical switches. This equipment typically includes multiple functional modules, such as stamping, drilling, forming, and surface treatment. Specifically, in the drilling process, existing equipment drives the drill bit downward and, in conjunction with the rotating drill bit, drills holes in the switch moving contact, thereby providing the necessary hole positions for subsequent fixing of the moving contact to other components (such as bases and conductive sheets) by means of bolts or riveting.

[0003] Existing switch moving contact production equipment uses a driven drill bit to move downwards and, in conjunction with a rotating drill bit, drills holes in the switch moving contact. This drilling is used to subsequently fix the moving contact to other components (such as bases or conductive sheets) via bolts or riveting. However, switch moving contacts generally require multiple holes. To improve drilling efficiency, two drill bits are typically used for simultaneous drilling. However, the spacing between the two holes is fixed and cannot be adjusted. Since different models or designs of switch moving contacts may require different hole spacings, the fixed-spacing drill bit cannot meet these diverse needs, thus limiting the application range of the equipment. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a switch moving contact production equipment. The adjustable drill bit spacing design enables the equipment to quickly adapt to the production needs of switch moving contacts of different specifications without the need for frequent drill bit replacements or equipment reconfiguration, greatly improving the flexibility of equipment production.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a switch moving contact production equipment, including a processing table, a switch moving contact placed on the upper end of the processing table, a connecting frame plate provided on the outer side of the processing table, the processing table and the connecting frame plate being fixed by welding, multiple guide columns being slidably arranged inside the connecting frame plate, a cross frame being provided between the lower ends of the multiple guide columns, multiple motors being slidably arranged inside the cross frame, and drill bits being provided on the output shafts of the multiple motors via couplings, an electric push rod II being provided at the upper end of the connecting frame plate, the telescopic end of the electric push rod II being connected to... The upper end of the cross frame is connected, and the inside of the cross frame is equipped with an adjustment mechanism for adjusting the drill bit spacing. The adjustment mechanism includes two rotating seats that are slidably set inside the cross frame. Each of the two rotating seats has two connecting rods rotatably set inside. Connecting seats are set on the left and right sides of the two motors respectively. The ends of the four connecting rods away from the rotating seats are rotatably connected to the interior of the adjacent connecting seats respectively. A double-acting screw is rotatably set inside the cross frame. The two rotating seats are threadedly connected to the left and right corresponding ends of the double-acting screw respectively. A knob is set on the right end of the double-acting screw. The double-acting screw and the knob are fixed together by welding.

[0006] As a further improvement of this utility model, a supporting and fixing base plate is provided at the lower end of the processing table, and multiple mounting holes are opened inside the supporting and fixing base plate.

[0007] As a further improvement of this utility model, two rectangular plates are provided at the upper end of the processing table. Two limiting posts are slidably provided inside each of the two rectangular plates. A clamping plate is provided between two adjacent limiting posts. The two clamping plates are in contact with the movable contact of the switch. A driving unit for driving the clamping plates to move is provided on the outer surface of the rectangular plates. The driving unit includes an electric push rod 1 respectively provided on the outer side of the two rectangular plates. The telescopic ends of the two electric push rods 1 are respectively connected to the outer side of the adjacent clamping plates.

[0008] As a further improvement of this utility model, a support frame is provided at the lower end of the processing table, and the processing table and the support frame are fixed together by welding. A collection box is provided inside the support frame, and a slot is opened inside the processing table.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, by placing the switch moving contact piece that needs to be drilled on the upper end of the processing table and positioning it between two clamping plates, and then abutting it against the limiting block behind it, the electric push rod is then opened and operated. As the clamping plates on both sides move closer to each other under the restriction of the limiting post, the switch moving contact pieces of different sizes can be clamped and fixed for subsequent drilling operations.

[0011] Secondly, by rotating the knob in both directions, the drill bits on the motor driven by the connecting seat move away from or closer to each other inside the cross frame, thereby adjusting the drill bit spacing. The adjustable drill bit spacing design allows the equipment to quickly adapt to the production needs of different specifications of switch moving contact pieces without the need for frequent drill bit replacements or equipment reconfiguration, greatly improving the flexibility of equipment production.

[0012] Third, the metal shavings generated by drilling can fall into the collection box through the slot. Then, the collection box can be slid out from the inside of the support frame to collect the metal shavings inside, thus avoiding the need for personnel to frequently clean the metal shavings on the processing table.

Detailed Implementation

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 1 , 2As shown, a switch moving contact production equipment includes a processing table 101. A switch moving contact 105 is placed on the upper end of the processing table 101. A connecting frame plate 201 is provided on the outer side of the processing table 101. Multiple guide posts 202 are slidably arranged inside the connecting frame plate 201. A cross frame 204 is provided between the lower ends of the multiple guide posts 202. Multiple motors 205 are slidably arranged inside the cross frame 204. Drill bits 211 are provided on the output shafts of the multiple motors 205 through couplings. An electric push rod 203 is provided on the upper end of the connecting frame plate 201. The telescopic end of the electric push rod 203 is connected to the upper end of the cross frame 204. The internal structure of the character frame 204 is equipped with an adjustment mechanism for adjusting the spacing of the drill bits 211. The upper end of the processing table 101 is provided with two rectangular plates 301. Two limiting posts 303 are slidably arranged inside each of the two rectangular plates 301. A clamping plate 304 is arranged between two adjacent limiting posts 303. The two clamping plates 304 are in contact with the switch moving contact 105. The outer surfaces of the rectangular plates 301 are respectively provided with driving units for driving the clamping plates 304 to move. The driving units include electric push rods 302 respectively arranged on the outer surfaces of the two rectangular plates 301. The telescopic ends of the two electric push rods 302 are respectively connected to the outer surfaces of the adjacent clamping plates 304.

[0021] like Figure 3 , 4 As shown, the adjustment mechanism includes two rotating seats 208 slidably disposed inside the cross frame 204. The two rotating seats 208 are positioned correspondingly to each other. Two connecting rods 207 are rotatably disposed inside each of the two rotating seats 208. Connecting seats 206 are respectively disposed on the left and right sides of the two motors 205. The ends of the four connecting rods 207 away from the rotating seats 208 are rotatably connected to the interior of the adjacent connecting seats 206. A bidirectional lead screw 210 is rotatably disposed inside the cross frame 204. The two rotating seats 208 are threadedly connected to the corresponding left and right ends of the bidirectional lead screw 210. A knob 209 is disposed on the right end of the bidirectional lead screw 210.

[0022] like Figure 1 As shown, a support and fixing base plate 104 is provided at the lower end of the processing table 101. The support and fixing base plate 104 has multiple mounting holes inside. The support and fixing base plate 104 supports the production equipment on the one hand, and fixes it in a suitable position through the multiple mounting holes inside.

[0023] By placing the switch movable contact piece that needs to be drilled on the upper end of the processing table 101 and positioning it between two clamping plates 304, and then abutting it against the limiting block behind it, the operation of the first electric push rod 302 is controlled to be opened. The telescopic end drives the clamping plates 304 on both sides to move closer to each other under the restriction of the limiting post 303 to clamp the switch movable contact piece. Then, by controlling the operation of the second electric push rod 203 and the operation of the motor 205, the telescopic end moves the drill bit 211 driven by the motor 205 downward to contact the switch movable contact piece 105, and continues to move downward to realize the drilling production of the switch movable contact piece 105.

[0024] When it is necessary to adjust the spacing of drill bits 211, the bidirectional lead screw 210 is rotated by rotating the knob 209 in both directions. This causes the rotating seats 208 on both sides to move closer or further apart under the constraint of the cross frame 204. The connecting rods 207 on both sides are then rotated to converge or retract. This causes the drill bits 211 on the motor 205 to move closer or further apart inside the cross frame 204 via the connecting seat 206, thereby adjusting the spacing of drill bits 211.

[0025] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, a support frame 102 is provided at the lower end of the processing table 101, and a collection box 103 is provided inside the support frame 102. A slot is opened inside the processing table 101, and the metal chips generated by drilling can fall into the collection box 103 through the slot. Then, the personnel can slide the collection box 103 out from the inside of the support frame 102 to collect the metal chips inside.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
