Description

Technical Field

[0001] This utility model belongs to the technical field of terminal assembly equipment, specifically relating to an integrated device for punching and crimping terminal blocks. Background Technology

[0002] The stator is the stationary part of the motor, generally consisting of an iron core A and windings B. During the motor manufacturing process, several terminals C are plugged into the stator, such as... Figure 1 As shown, the terminal block serves as the port for connecting the winding to the external circuit.

[0003] When assembling terminals on a motor, strip terminals are usually selected. A punching structure is used to cut the strip terminals into multiple independent terminals. Then, a conveying mechanism is used to transport the terminals to the stator, aligning the terminals with the holes to be connected on the stator. Finally, a pressing mechanism presses the terminals onto the stator, completing the assembly of the terminals.

[0004] This process employs a punching mechanism, a transport mechanism, and a pressing mechanism. Each step in the terminal assembly is independently configured. For example, Chinese Patent No. CN114193705A discloses a terminal carrier punching device and punching method, and Chinese Patent No. CN106374319B discloses a terminal crimping device. In other words, the terminal needs to be transported and positioned multiple times during motor production. The use of the transport mechanism increases equipment costs and extends the motor production cycle. Utility Model Content

[0005] This utility model provides an integrated device for punching and crimping terminal blocks, which solves the problem of long punching and crimping time required for current terminal block punching and crimping processes.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a terminal punching and crimping integrated device, including a mold core set in the center of the opening and closing mold, a clamping cylinder that penetrates the template on one side of the opening and closing mold and presses and fixes the terminal on the mold core, a punching cylinder that drives the punch to penetrate the template on the other side of the opening and closing mold and punch the terminal, and a crimping mechanism that directly crimps the terminal onto the motor.

[0007] The crimping mechanism includes a punch, a clamping plate, and a lifting assembly. The bottom of the punch has a groove for engaging the terminal block. A contact portion is provided on one side of the groove. The clamping plate passes through the groove from the side where the contact portion is located and connects to a limiting portion. The limiting portion can rotate after being driven to cooperate with the contact portion to clamp the terminal block. The lifting assembly is used to push the punch and the clamping plate to move up and down synchronously.

[0008] Specifically, the terminal block has a V-shaped groove, and the terminal block is inserted into the groove, and the clamping piece is inserted into the V-shaped groove.

[0009] Specifically, the top end of the limiting part extends beyond the top of the groove, and the bottom end of the limiting part extends beyond the bottom of the V-shaped groove.

[0010] Specifically, the lamination is provided with rollers.

[0011] Specifically, the top of the clamping plate is connected to a transmission structure, which is connected to a clamping cylinder. The transmission structure converts the linear motion output by the clamping cylinder into rotational motion to drive the clamping plate to rotate.

[0012] Specifically, the lifting assembly includes a motor, a lead screw connected to the motor, a lifting plate disposed on the lead screw, and a terminal crimping depth measuring structure. As the lead screw rotates, the lifting plate moves in the vertical direction. A mounting block is fixedly connected to the top of the lamination, and the mounting block is fixedly connected to the lifting plate.

[0013] Specifically, the two templates of the opening and closing mold are provided with clearance holes for the punching pieces and clamping pieces to pass through.

[0014] Specifically, one side of the mold is a die base, and the other side is a die. The die base has a first through hole, which is opposite to the die core. The output end of the clamping cylinder can pass through the first through hole. The die has a second through hole, which is opposite to the side of the die core. The punch can pass through the second through hole.

[0015] Specifically, the punch is connected to a slide rod, the die has a first track hole parallel to the second through hole, the die core has a second track hole that mates with the first track hole, and the slide rod is inserted into the first track hole and the second track hole in sequence and slides relative to the first track hole and the second track hole.

[0016] Specifically, it also includes a feeding mechanism, which includes a strip terminal guide rail, a ratchet disposed on one side of the strip terminal guide rail, and a feeding cylinder that drives the ratchet to rotate. The ratchet is used to push the strip terminal to move along the strip terminal guide rail.

[0017] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0018] 1. The opening and closing mold, punching structure, pressing structure, and clamping structure required for punching and pressing are all integrated into the opening and closing mold. The punching and pressing of the terminal block are combined, and the terminal block is directly assembled to the stator in an integrated stamping operation mode. There is no need to use a handling structure, thereby saving time and space, improving efficiency and reducing costs.

[0019] 2. Set up mutually cooperating clamping plates and clamping plates. The clamping plates have a smaller opening and closing range than the clamping plates, reducing the space occupied in the opening and closing mold. In addition, the bottom of the clamping plates and the bottom of the clamping plates cross each other, ensuring stable clamping and preventing the wiring terminals from easily loosening or shifting.
