Description

Technical Field

[0001] This utility model belongs to the field of sliding contact line technology, specifically relating to a sliding contact line traction base plate processing device. Background Technology

[0002] In the processing of the conductor rail traction base plate, punching is a crucial step in shaping key structures such as mounting holes and connection holes. This step directly affects the assembly accuracy of the traction base plate with the current collector and mobile equipment, as well as the stability of subsequent power transmission. Currently, the industry mostly uses traditional stamping equipment for punching the conductor rail traction base plate, using a stamping head to press the blank into shape to quickly obtain the hole structure that meets the dimensional requirements.

[0003] After punching, the inner wall of the hole is prone to burrs and flash due to the plastic deformation of the material, and the edge of the hole may be uneven. If these defects are not addressed, they can lead to problems such as jamming and improper assembly during the subsequent installation of the current collector. In fact, during long-term use of the traction base plate, the burrs may wear down the wires, affecting the safety of power transmission.

[0004] Existing stamping equipment only has the function of punching holes and cannot directly grind the inside and outside of the holes after punching. The traction base plate that has been punched needs to be removed from the stamping equipment and transferred to the grinding equipment for a separate grinding process inside the holes. This not only increases the number of times the workpiece is handled and the labor cost, but also extends the processing cycle and reduces production efficiency due to multiple transfers.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-5 A sliding contact line traction base plate processing device includes: a processing table 100; a control box 200 installed on the processing table 100; a stamping seat 300 installed inside the control box 200, with the bottom end of the stamping seat 300 penetrating through the bottom wall of the control box 200; a first power source 201 installed on the top wall of the control box 200, with the power shaft of the first power source 201 connected to the stamping seat 300; a connecting rod 301 penetrating through the stamping seat 300, with a grinding head 306 installed at the bottom end of the connecting rod 301; and a stamping head 307 installed at the bottom end of the grinding head 306.

[0025] In this embodiment, by integrating punching and grinding functions into the same processing station, after the first power source 201 drives the punching head 307 to perform punching operations, it continues to drive the punching head 307 to move, so that the grinding head 306 can enter the punching hole and grind the hole. This realizes continuous processing of grinding the hole immediately after punching, improving efficiency and reducing workpiece transfer errors. The first power source 201 adopts a hydraulic cylinder or a pneumatic cylinder to provide the main driving force required for punching and drive the punching head 307 to complete the punching.

[0026] The stamping base 300 includes: a through hole formed on the stamping base 300, a connecting rod 301 disposed in the through hole; a connecting seat 302 installed on the top of the connecting rod 301, and the connecting seat 302 disposed on the top of the stamping base 300; a first gear 303 sleeved on the connecting seat 302; and a second power source 304 installed on the stamping base 300, with a second gear 305 connected to the power shaft of the second power source 304, and the second gear 305 meshing with the first gear 303.

[0027] By setting the connecting rod 301 inside the through hole, the stamping action can be achieved while the grinding head 306 can be rotated. The second power source 304 drives the second gear 305 to rotate, the second gear 305 drives the first gear 303 and the connecting seat 302 to rotate, and the connecting seat 302 drives the connecting rod 301 and the grinding head 306 to rotate, so that the grinding head 306 can grind the inside of the hole.

[0028] An assembly plate 308 is fitted onto the stamping base 300. A second power source 304 is installed on the assembly plate 308. An elastic element 309 is installed between the bottom wall of the control box 200 and the assembly plate 308. The elastic element 309 provides buffering during the stamping process to avoid rigid impact damage to the equipment. After the stamping is completed, it helps the stamping base 300 to reset.

[0029] The top of the connecting seat 302 has a groove, and the power shaft of the first power source 201 is set in the groove. The power shaft of the first power source 201 is movably connected to the connecting seat 302. During the stamping operation, after the power shaft of the first power source 201 moves into the groove, it continues to push the connecting seat 302. The connecting seat 302 drives the stamping seat 300 and the connecting rod 301 to move together, which can drive the stamping head 307 to perform the stamping operation. When the second power source 304 drives the connecting rod 301 and the connecting seat 302 to rotate, the connecting seat 302 can rotate on the power shaft of the first power source 201. The second power source 304 can be a servo motor or a stepper motor.

[0030] The grinding head 306 is equipped with a first threaded head, which is threadedly connected to the connecting rod 301. The punching head 307 is equipped with a second threaded head, which is threadedly connected to the grinding head 306. The second threaded head and the first threaded head are coaxially arranged. The bottom ends of the connecting rod 301 and the grinding head 306 are provided with threaded grooves, and the first threaded head and the second threaded head are respectively threadedly connected to the two threaded grooves. The threaded connection structure (first threaded head and second threaded head) realizes the detachable connection between the punching head 307, the grinding head 306 and the connecting rod 301, which facilitates the replacement of the corresponding tool head according to different specifications of the traction base plate, improves the versatility of the equipment, and also facilitates replacement after wear, reducing maintenance costs.

[0031] The top of the processing table 100 is provided with a mounting groove, in which a support base 400 is installed. A grinding disc is provided on the top of the support base 400, and a stamping hole is provided on the support base 400. A third gear 401 is fitted onto the support base 400. A third power source 403 is installed on the processing table 100, and a fourth gear 402 is connected to the power shaft of the third power source 403. The fourth gear 402 meshes with the third gear 401. The support base 400 has two functions: firstly, to provide support for the stamping of the sliding contact line traction base plate. The first function is to provide support to ensure that the area around the punched hole does not deform, and to facilitate the discharge of punching waste. The second function is to grind the lower surface of the base plate after punching, removing any burrs that may be present. After punching, the third power source 403 drives the fourth gear 402 to rotate, the fourth gear 402 drives the third gear 401 to rotate, and the third gear 401 drives the support base 400 and the grinding disc to rotate. Through rotational grinding, the consistency of the circumferential direction of the hole opening is ensured. The third power source 403 is a servo motor, but a stepper motor can also be used.

[0032] During use, the conductor rail traction base plate blank to be processed is placed on the support seat 400 of the processing table 100, so that the position of the blank to be punched is aligned with the punching hole of the support seat 400. According to the hole size requirements of the traction base plate, the appropriate punching head 307 and grinding head 306 are replaced through the threaded connection structure of the first threaded head and the second threaded head. The diameters of the grinding head 306 and the punching head 307 need to be the same.

[0033] An external controller starts the first power source 201, whose power shaft extends downward and first enters the groove at the top of the connecting seat 302. Then, it pushes the connecting seat 302 downward through the bottom of the groove. The connecting seat 302 drives the stamping seat 300 and the connecting rod 301 to move downward synchronously. The stamping seat 300 pushes the assembly plate 308 sleeved on it to compress the elastic element 309, and finally drives the stamping head 307 at the bottom of the grinding head 306 to contact the blank. The stamping head 307 continues to press down to stamp the blank. The waste generated by punching is discharged through the punching hole of the support seat 400. At the same time, the support seat 400 provides rigid support for the punching area of ​​the blank.

[0034] After punching is completed, the first power source 201 continues to drive the punching head 307 downward, so that the grinding head 306 enters the punching hole. The second power source 304 is activated, which drives the second gear 305 to rotate. The second gear 305 meshes with and drives the first gear 303 to rotate, which in turn drives the connecting rod 301 and the grinding head 306 to rotate synchronously through the connecting seat 302. The rotating grinding head 306 grinds the inner wall of the hole. The third power source 403 is activated simultaneously, which drives the fourth gear 402 to rotate. The fourth gear 402 meshes with and drives the third gear 401 to rotate, which drives the support seat 400 and the grinding disc on the top to rotate. The rotating grinding disc grinds the lower surface of the blank punching position.

[0035] After grinding is completed, the second power source 304 and the third power source 403 stop rotating, the grinding head 306 and the grinding disc are stationary, the power shaft of the first power source 201 retracts upward, the elastic element 309 releases its elastic force, pushing the assembly plate 308 and the stamping seat 300 to reset upward, the connecting rod 301, the grinding head 306 and the stamping head 307 rise synchronously with the stamping seat 300, detach from the blank, and the operator removes the processed traction base plate from the support seat 400. If continuous processing is required, the above process can be repeated.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
