Description

Technical Field

[0001] The present application relates to the technical field of motor lead wires, and in particular to a riveting device for motor lead wires. Background Art

[0002] Motor lead wires are wires specially used to connect motors and other electrical equipment. They play a vital role in the operation of the motor, ensuring that the motor can work safely and stably.

[0003] In the prior art, such as Figure 1 Both ends of the motor lead wire 9 are provided with connecting pieces 8 for connection. The connecting piece 8 includes a circular connecting disc 81 with a circular hole and two pressing pieces 82 pressed against the lead wire 9. The two pressing pieces 82 are stamped by a riveting device to form multiple planes and are fixedly pressed against the lead wire 9.

[0004] The riveting device includes a fixed die and a movable die. The movable die moves up and down to place the connecting piece and the lead wire on the fixed die in turn. The movable die moves down until the movable die abuts against the fixed die to complete the stamping of the pressing piece. However, the pressing piece has a certain resilience after stamping, and the movable die cannot continue to move after abutting against the fixed die. Therefore, the pressure on the pressing piece will be reduced. When the movable die moves up, the two pressing pieces are prone to rebound, thereby reducing the firmness of the connection between the connecting piece and the lead wire and reducing the riveting quality of the lead wire. Summary of the invention

[0007] By adopting the above technical solution, two pressing sheets are placed on the lower mold cavity, and then the lead wires are placed on the two pressing sheets, and then the lifting assembly is started to drive the movable mold to move downward, so that the upper mold cavity is pressed against the lead wire to squeeze the lead wire downward, and the lead wire squeezes the two pressing sheets into the lower mold cavity, and the two pressing sheets are deformed and pressed against the upper mold cavity, and then the upper mold continues to move downward, and the upper mold cavity squeezes the two pressing sheets until the extrusion surface one is tightly pressed against the guide surface one, and the extrusion surface two is tightly pressed against the guide surface two for positioning, so that the movable mold maintains its position, and then the movable mold moves up and away from the movable mold, and the lead wire riveting is completed in this way.

[0008] By pressing the inclined extrusion surface one against the guide surface one and the inclined extrusion surface two against the guide surface two for positioning, the movable die can form a downward inclined partial pressure on the two pressing pieces, and the partial pressure can continue to realize the extrusion shaping of the two pressing pieces, reducing the risk of the pressing pieces rebounding, thereby improving the riveting quality of the lead wire.

[0009] Optionally, the guide surface one and the guide surface two are parallel to each other, the guide surface one is flush with one side wall of the lower mold cavity and the extrusion surface two is flush with one side wall of the upper mold cavity, or, the guide surface two is flush with one side wall of the lower mold cavity and the extrusion surface one is flush with one side wall of the upper mold cavity.

[0010] By adopting the above technical solution, the guide surface one and the guide surface two are parallel to each other, so that the resistance is minimal when they are in close contact with the extrusion surface one and the extrusion surface two, that is, the downward tilting force is maximized, that is, the extrusion force on the two pressing pieces is maximized, further reducing the risk of the pressing pieces rebounding; the design flush with the lower mold cavity and the upper mold cavity is to make it easier for the two pressing pieces to contact with the upper mold cavity and the lower mold cavity, thereby making it easier to rivet the pressing pieces, thereby improving the riveting quality of the lead wires.

[0011] Optionally, the fixed mold and the movable mold are provided with a positioning mechanism for positioning the connecting piece and the lead wire, and the positioning mechanism includes: The first positioning plate and the second positioning plate are both set on the machine body and located on both sides of the fixed mold by sliding up and down through the elastic component. The connecting disc is clamped and installed on the first positioning plate to position the connecting plate. The second positioning plate is arc-shaped and is positioned for placing the lead wire. The elastic component positions the first positioning plate and the second positioning plate under the action of elastic force. The pressing assembly is arranged on the movable mold; when the movable mold moves downward, the pressing assembly is driven to press against the connecting disc and the lead wire respectively for positioning and continues to move downward to push the pressing assembly, the positioning plate 1 and the positioning plate 2 to move downward at the same time; when the movable mold moves upward, the pressing assembly is driven to move upward, and the positioning plate 1 and the positioning plate 2 move back to their original positions under the action of the elastic assembly.

[0012] By adopting the above technical scheme, the connecting disc is clamped and installed on the positioning plate one, and then one end of the lead wire is placed on the two pressing plates and the other end is placed on the positioning plate two. The movable mold moves downward to drive the pressing assembly to move downward, and the pressing assembly presses on the connecting disc and the lead wire for positioning. The movable mold moves downward to punch the two pressing plates, and the pressing assembly pushes the positioning plate one and the positioning plate two to squeeze the elastic assembly downward, so that the pressing plate can be positioned when it is punched. After the riveting is completed, the movable mold moves upward to drive the pressing assembly to move upward, and the positioning plate one and the positioning plate two both move upward under the action of the elastic assembly, thereby pushing the connecting piece and the lead wire to move upward and disengage from the lower mold cavity, and the upper mold continues to move upward to disengage the connecting piece from the upper mold cavity, and at the same time, the pressing assembly disengages from the connecting disc and the lead wire, thereby realizing the connection between the connecting piece and the lead wire.

[0013] The connection plate and the lead wire are positioned by the cooperation of the positioning plate 1, the positioning plate 2 and the pressing assembly, thereby improving the accuracy of the position of the connection plate and the lead wire after connection. At the same time, the positioning plate 1 and the positioning plate 2 can be moved upward to push the pressing plate out of the lower mold cavity, and the upper mold can be moved upward to separate the pressing plate from the upper mold cavity, thereby greatly improving the convenience during removal and improving the riveting quality and efficiency of the lead wire.

[0014] Optionally, the elastic component includes: Guide rods are arranged on the machine body and at least two guide rods are arranged at intervals and are both slidably penetrated on the first positioning plate; A fixing nut, threadedly connected to the guide rod; The spring is sleeved on the guide rod and presses against the machine body and the positioning plate 1 to push the positioning plate 1 to keep the tendency of moving upward.

[0015] By adopting the above technical solution, the spring pushes the positioning plate to maintain an upward movement trend, and the pressing assembly can squeeze the spring when pushing the positioning plate to move down. When the pressing assembly moves upward, the spring pushes the positioning plate to move upward. At the same time, after the fixing nut is removed from the guide rod, the positioning plate and the spring can be removed and replaced, further ensuring that the positioning plate maintains an upward trend.

[0016] Optionally, the pressing component includes: The first pressing plate and the second pressing plate are arranged on the movable mold and are pressed against the connecting disc and the lead wire respectively for positioning.

[0017] By adopting the above technical solution, the first pressing plate and the second pressing plate are respectively mortgaged on the connecting disc and the lead wire for positioning.

[0018] Optionally, the second pressure plate is arc-shaped and is arranged to fit the lead wire, and the first pressure plate and the second pressure plate are detachably arranged from the movable mold.

[0019] By adopting the above technical scheme, the second pressure plate can better cooperate with the first pressure plate to clamp and position the lead wire, thereby improving the positioning effect, that is, improving the quality of riveting; at the same time, the first pressure plate and the second pressure plate can be detachably arranged, so that the first pressure plate and the second pressure plate of different sizes can be better used to position the connecting pieces and lead wires with different requirements, thereby improving the adaptability of riveting.

[0020] Optionally, the movable die is provided with an extrusion mechanism, and the extrusion mechanism comprises: An extrusion piece is rotatably mounted on the movable die and can be rotated to the inside or outside of the upper die cavity; A driving member, used for driving the extrusion member to rotate; The control component is arranged on the machine body and is electrically connected to the lifting component. After the extrusion piece is transferred to the upper mold cavity, it moves downward under the action of the movable mold and is used to extrude the connecting piece into the lower mold cavity and then move upward under the action of the movable mold. After the extrusion piece is transferred to the outside of the upper mold cavity, the lead wire is placed on the positioning plate 2 for positioning. The downward movement of the movable mold is used to realize the positioning of the connecting piece by riveting it to the lead wire.

[0021] By adopting the above technical solution, the connecting disc is first clamped and installed on the positioning plate, and then the driving member drives the extrusion member to rotate to the inner side of the upper mold cavity, and the control component controls the lifting component to drive the movable mold to move downward, and the movable mold moves downward to drive the pressing component and the extrusion member to move downward. After the pressing component is pressed on the connecting disc, the extrusion member can extrude the two pressing pieces, so that the two pressing pieces are pressed into the lower mold cavity, so that the two pressing pieces are initially formed.

[0022] The movable mold moves upward, and the positioning plate moves upward to push the two pressing pieces out of the lower mold cavity. At this time, the two initially formed pressing pieces will rebound a part and increase the distance between the two pressing pieces, so as to facilitate placing one end of the lead wire between the two initially formed pressing pieces. Then the movable mold moves downward to squeeze the two pressing pieces again. Finally, the two pressing pieces are pressed against the lead wire to connect the connecting piece with the lead wire.

[0023] The two pressing pieces are initially formed by extrusion through an extrusion piece. Compared with directly extruding the two pressing pieces with lead wires, the risk of extrusion damage to the lead wires is greatly reduced. It is equivalent to extruding the pressing piece twice, thus further reducing the risk of springback of the pressing piece and greatly improving the riveting quality of the lead wires.

After the movable mold moves down to drive the extrusion part to squeeze the pressing piece into the lower mold cavity, it senses with sensor 2 and stops moving. Sensor 2 is turned off. When the movable mold moves down to complete riveting the pressing piece, it stops after sensing with sensor 3. After the movable mold completes riveting and moves up, sensor 2 restarts.

[0025] By adopting the above technical scheme, the driving part drives the extrusion part to rotate to the inner side of the upper mold cavity, and the movable mold moves downward to drive the extrusion part to extrude the two pressure pieces. At this time, the second sensor senses the movable mold, thereby controlling the lifting assembly to drive the movable mold to move up to the highest point, and the first sensor senses the movable mold to control the movable mold to stop moving; the driving part drives the extrusion part to rotate to the outer side of the upper mold cavity, and the second sensor is closed; after the movable mold moves downward to complete the riveting of the two pressure pieces, the third sensor senses the movable mold, thereby controlling the lifting assembly to drive the movable mold to move up, the first sensor senses the movable mold, controls the movable mold to stop moving, and the second sensor restarts, thereby realizing the control of the movable mold to move as needed, saving time, and improving the riveting quality and efficiency of the lead wires.

[0027] By adopting the above technical solution, the positions of sensor 1, sensor 2 and sensor 3 can be adjusted, so as to adapt to the inductive positioning of connecting pieces and lead wires with different requirements.

[0028] Optionally, the lifting assembly includes: A fixed seat is arranged on the machine body, the fixed mold is arranged on the fixed seat and the movable mold is arranged on the fixed seat for vertical sliding movement; The lifting member is arranged on the machine body and the piston rod is connected with the fixing seat.

[0029] By adopting the above technical solution, the lifting member starts to drive the movable mold to move, and the fixed seat is used to guide the movement of the movable mold, thereby improving the accuracy of the movable mold when moving.

[0030] In summary, the present application includes at least one of the following beneficial technical effects: 1. By pressing the inclined extrusion surface 1 against the guide surface 1, and the inclined extrusion surface 2 against the guide surface 2 for positioning, the movable die can form a downward inclined partial pressure on the two pressing pieces, and the partial pressure can continue to realize the extrusion shaping of the two pressing pieces, reducing the risk of the pressing pieces rebounding, thereby improving the riveting quality of the lead wire.

[0031] 2. The connection plate and the lead wire are positioned by the cooperation of the positioning plate 1, the positioning plate 2 and the pressing assembly, which improves the accuracy of the position of the connection plate and the lead wire after connection. At the same time, the positioning plate 1 and the positioning plate 2 can be moved upward to push the pressing plate out of the lower mold cavity, and the upper mold can be moved upward to separate the pressing plate from the upper mold cavity, thereby greatly improving the convenience of removal and improving the quality and efficiency of the riveting of the lead wire.
