DETAILED DESCRIPTION

[0020] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1-Figure 7 As shown, an embodiment of the present invention provides a high-strength and high-conductivity contact material preparation device, comprising:

[0022] The frame 1 has a support plate 2 installed inside the frame 1, a connecting rod 3 is constructed on the support plate 2, a rotating disk 4 is rotatably installed on the outer peripheral side of the connecting rod 3, and a motor for driving the rotating disk 4 to rotate is installed on the connecting rod 3. For example, Figure 4 As shown, a side plate is installed on one side of the connecting rod 3, the motor is installed on the side plate, the output shaft of the motor and the bottom of the rotating disk 4 are both installed with bevel gears, the two bevel gears are meshed with each other to achieve the driving of the rotating disk 4, the connection method between the motor and the rotating disk 4 is the existing conventional technology, an electric slide bar 6 is vertically installed on the support plate 2, an electric welding frame 7 is vertically installed on the electric slide bar 6, and a laser welding head 11 is installed on the electric welding frame 7;

[0023] The support mechanism 8 includes a rotating part 9 installed in a circular array on the outer peripheral side of the rotating disk 4, and the top of the rotating part 9 is used to install a welding fixture;

[0024] The trigger mechanism 10 comprises an execution part 1001 and a trigger part 1002. The execution part 1001 is mounted on the electric slide bar 6 and acts on the electric welding frame 7. The trigger part 1002 is mounted on the rotating part 9. When the electric welding frame 7 moves downward, the execution part 1001 drives the trigger part 1002 to rotate the rotating part 9 at a fixed angle. That is to say, when in use, the welding fixture is mounted on the rotating part 9, and then the collector ring is mounted on the welding fixture, and then the electric slide bar 6 is started and then the electric welding frame 7 moves downward. In this process, the execution part 1001 contacts the trigger part 1002. , thereby causing the rotating part 9 located below it to rotate, and then causing the welding points of the collector ring to rotate, so as to weld one of the welding points of the collector ring installed on the welding fixture. After the welding of one of the welding points is completed, the electric welding frame 7 moves upward and no longer contacts the collector ring. At this time, the electric welding frame 7 moves downward. During this process, the execution part 1001 contacts the trigger part 1002 again, causing the rotating part 9 to rotate again, and so on, thereby being able to continuously complete the welding of multiple welding points of the collector ring on the rotating part 9, thereby improving the overall continuity and further improving the welding efficiency.

[0025] like Figure 3 and Figure 4 As shown, in some embodiments, a plurality of slots 901 are provided in a circular array on the outer circumference of the rotating disk 4, and the rotating part 9 includes a mounting sleeve 902 installed on the slot 901, a mounting rod 903 is vertically constructed at the bottom of the mounting sleeve 902, and a connecting disk 904 is constructed on the outer circumference of the mounting rod 903, and a mounting cylinder 905 is rotatably installed on the outer circumference of the connecting disk 904, and the bottom of the mounting cylinder 905 is inserted into the top of the mounting sleeve 902, and the trigger part 1002 is installed on the mounting rod 903, that is, when the execution part 1001 contacts the trigger part 1002, it will drive the mounting cylinder 905 to rotate, thereby causing the welding fixture installed on the mounting cylinder 905 to rotate. Specifically, the mounting cylinder 905 is cylindrical and has a flat top, which is used to install the welding fixture, and the outer circumference of the mounting cylinder 905 is movably inserted into the top of the mounting sleeve 902, so as to effectively prevent external welding slag from entering the mounting sleeve 902.

[0026] like Figure 2-Figure 3As shown, in some embodiments, the execution part 1001 includes a moving plate 10012 slidably arranged on the electric slide bar 6, a return spring 10013 is installed between the moving plate 10012 and the electric slide bar 6, a convex plate 10014 is configured at the bottom end of the moving plate 10012, and a contact part 10011 is configured on the convex plate 10014, which is used to contact with the trigger part 1002. When the electric welding frame 7 moves downward, it will contact the moving plate 10012, and the moving plate 10012 will move downward. The reset spring 10013 is compressed, and as the movable disk 10012 moves downward, the contact portion 10011 installed on the convex plate 10014 will contact the trigger portion 1002, thereby starting the trigger portion 1002 to drive the installation cylinder 905 to rotate. When the electric welding frame 7 moves upward, the reset spring 10013 will reset due to its own elastic deformation. At this time, the installation cylinder 905 will not rotate, to ensure that the contact portion 10011 can drive the installation cylinder 905 to rotate again next time.

[0027] like Figure 3 As shown, in some embodiments, the triggering part 1002 includes a sliding ring 10021 vertically slidably sleeved on the mounting rod 903, and a driving plate 10022 is horizontally configured at one end of the sliding ring 10021. A return spring 10023 is installed between the driving plate 10022 and the bottom end of the mounting sleeve 902. The driving plate 10022 is used to contact the contact part 10011. A linkage 12 is installed between the driving plate 10022 and the mounting cylinder 905. When the driving plate 10022 moves downward, the mounting cylinder 905 is driven to rotate through the linkage 12. That is to say, when the contact is When the contact portion 10011 moves downward and contacts the driving plate 10022, the driving plate 10022 will drive the mounting tube 905 to rotate through the linkage 12 during the downward movement. At this time, the return spring 10023 is in a compressed state. When the contact portion 10011 is no longer in contact with the driving plate 10022, the return spring 10023 will be reset, and the linkage 12 will not drive the mounting tube 905 to rotate again. In other words, the mounting tube 905 will only rotate in one direction without reversal, thereby ensuring that repeated welding will not occur during the welding process.

[0028] like Figure 3 and Figure 4As shown, in some embodiments, the contact portion 10011 includes a connecting cylinder 100112 horizontally constructed on the convex plate 10014, a wedge plate 100113 is horizontally slidably installed on one side of the connecting cylinder 100112, a connecting spring 100114 is installed between the wedge plate 100113 and the connecting cylinder 100112, and a driving inclined surface 100111 is constructed at the bottom end of the driving plate 10022, that is, when the wedge plate 100113 moves downward, the inclined surface of the wedge plate 100113 will contact the driving plate 10022, so that the driving plate 10022 moves downward, driving The plate 10022 moves downward and drives the mounting tube 905 to rotate through the linkage 12. When the mounting tube 905 moves to the corresponding angle, the convex plate 10014 continues to move downward, causing the wedge plate 100113 to retract into the connecting tube 100112 until it passes through the driving plate 10022. When the electric welding frame 7 moves upward, the reset spring 10013 will reset, causing the top plane of the wedge plate 100113 to contact the bottom driving inclined surface 100111 of the driving plate 10022. At this time, the wedge plate 100113 retracts until it is separated from the driving plate 10022 to complete the reset.

[0029] like Figure 4 As shown, in some embodiments, the linkage 12 includes a linkage rod 1201 hinged on the driving plate 10022, and the free end of the linkage rod 1201 is hinged with a rotating block 1206, and a sliding block 1202 is rotatably installed on the rotating block 1206. A rotating ring 1203 is rotatably installed on the outer peripheral side of the mounting rod 903, and an outer arc plate 1204 is constructed on the outer side of the rotating ring 1203 through a plate body. A sliding groove 1205 is opened at the bottom end of the outer arc plate 1204, and the sliding block 1202 is slidably installed in the sliding groove 1205. A one-way member 13 acting on the mounting cylinder 905 is installed on the outer arc plate 1204. When the driving plate 10022 moves downward to drive the outer arc plate 1204 to rotate, the mounting cylinder 905 is rotated in one direction through the one-way member 13. The design of the one-way member 13 effectively It is ensured that when the driving plate 10022 moves downward, the driving plate 10022 moves through the connecting rod 1201 to drive the rotating block 1206 to move, and the sliding block 1202 is slidably installed in the sliding groove 1205, so the connecting rod 1201 at this time will pull the outer arc plate 1204 to rotate, and the sliding block 1202 will move in the sliding groove 1205, and the rotating block 1206 will rotate adaptively, and the movement of the outer arc plate 1204 will cause the mounting tube 905 to rotate through the one-way member 13, and when the driving plate 10022 is elastically reset due to the return spring 10023, the outer arc plate 1204 will rotate in the opposite direction, but at this time the one-way member 13 will not drive the mounting tube 905 to rotate, thereby ensuring that the mounting tube 905 will not reverse.

[0030] like Figure 4As shown, in some embodiments, the one-way member 13 includes a mounting groove 1301 opened on one side of the outer arc plate 1204, a forcing plate 1302 is slidably installed in the mounting groove 1301, one end of the forcing plate 1302 is provided with a forcing inclined surface 1303, a plurality of wedge-shaped grooves 1304 for inserting the forcing plate 1302 are opened in a circular array on the inner circumference of the mounting cylinder 905, and a resisting spring piece 1305 is installed between the forcing plate 1302 and the mounting groove 1301, that is, when the outer arc plate 1204 rotates due to the downward movement of the driving plate 10022, at this time, a side plane of the forcing plate 1302 will contact the wedge-shaped groove 130 4, thereby driving the installation cylinder 905 to rotate. When the outer arc plate 1204 rotates because the driving plate 10022 moves upward, the forcing inclined surface 1303 of the forcing plate 1302 will contact the inclined surface of the wedge-shaped groove 1304, thereby not driving the installation cylinder 905 to rotate. For further optimization, a rubber ring for increasing friction can be set in the installation cylinder 905. The rubber ring and the installation sleeve 902 form a close fitting relationship through the rubber ring, thereby effectively preventing the installation cylinder 905 from accidentally rotating when the forcing inclined surface 1303 of the forcing plate 1302 contacts the inclined surface of the wedge-shaped groove 1304.

[0031] like Figure 4 and Figure 7 As shown, in some embodiments, a guide rod 14 is vertically constructed on the mounting sleeve 902, and the guide rod 14 passes through the driving plate 10022. The sliding sleeve of the guide rod 14 is provided with a limit block 15, and an adjusting component 16 for adjusting the moving position of the limit block 15 is installed on the connecting rod 3. That is to say, the position of the limit block 15 can be adjusted by the adjusting component 16, so that when the driving plate 10022 moves downward, when the driving plate 10022 moves to contact with the limit block 15, it will limit the driving plate 10022 from continuing to move downward. The design of the adjusting component 16 can adjust the rotation angle of the mounting tube 905 each time according to the welded collector ring welding point, thereby further improving the applicability.

[0032] like Figure 3 , Figure 4 and Figure 7As shown, in some embodiments, the adjustment component 16 includes a collar 1601 movably sleeved on the connecting rod 3, a plurality of long rods 1605 are provided on the outer peripheral side of the collar 1601, and the plurality of long rods 1605 are connected to the plurality of limit blocks 15, a connecting ring 1602 is rotatably sleeved on the outer peripheral side of the collar 1601, a connecting frame 1603 vertically slidably mounted on the frame body 1 is installed on the connecting ring 1602, an adjusting screw 1604 is vertically rotatably installed on the frame body 1, and the connecting frame 1603 is threadedly sleeved on the adjusting screw 1604, that is, rotating the adjusting screw 1604 will drive the vertical movement of the connecting frame 1603, thereby bringing The connecting ring 1602 connected to the connecting frame 1603 is moved. Because the connecting ring 1602 and the sleeve ring 1601 rotate in coordination, the sleeve ring 1601 is driven to move vertically. Because the sleeve ring 1601 is connected to multiple long rods 1605, multiple limit blocks 15 are moved, so that the rotation angles of multiple outer arc plates 1204 can be adjusted at the same time, which is more convenient for batch welding of collector rings. The sleeve ring 1601 is movably mounted on the connecting rod 3 without affecting the rotation of the rotating disk 4. Preferably, a scale can be set on the frame 1, and the rotation angle of the outer arc plate 1204 at this time can be intuitively observed through the scale.

[0033] like Figure 3 As shown, in some embodiments, a threaded cylinder 17 is coaxially constructed at the top of the movable disk 10012, and a threaded top cylinder 5 is threadedly sleeved on the threaded cylinder 17, which is used to contact the electric welding frame 7. The design of the threaded top cylinder 5 can ensure that the electric welding frame 7 can drive the rotation of the outer arc plate 1204 while moving in a small range, thereby further improving the welding efficiency.

[0034] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
