Description

Technical Field

[0001] This invention relates to the field of electrical contact processing technology, specifically to an electrical contact processing device for preventing wear, and also to a processing method for the electrical contact processing device for preventing wear. Background Technology

[0002] In the fields of power, electronics, and automation control, electrical contacts are key components, and their performance and quality directly affect the stability and reliability of the entire system. Electrical contacts must withstand frequent switching operations during use, making their surface quality and wear resistance crucial. Traditional electrical contact processing methods often employ manual or simple mechanized grinding. This approach is not only inefficient but also struggles to ensure consistent and uniform grinding, easily leading to uneven wear and increased contact resistance on the contact surface, thus affecting its service life and performance.

[0003] In the prior art, for example, Chinese utility model patent with authorization announcement number CN222134497U discloses a riveted type electrical contact protrusion processing equipment. Its working process is as follows: First, the electrical contact body is placed in the circular groove at the top of the rotating column for fixing. Then, the grinding belt is brought into contact with the position of the electrical contact body that needs to be ground, thereby using the grinding belt to grind the electrical contact. The electrical contact body is evenly inserted on each rotating column, and all the rotating columns are arranged in a straight line. Therefore, the grinding belt can contact and grind multiple electrical contact bodies at the same time. Moreover, the rotating column can rotate, and the slide rod used to install the grinding belt can rotate and slide using the connecting rod. Therefore, it is possible to perform grinding operations on different positions of the electrical contact body, which facilitates batch processing of protrusions on the electrical contact body and improves work efficiency.

[0004] Although the above solution achieves simultaneous grinding of multiple electrical contacts, resulting in consistent and uniform grinding effects, the multiple electrical contacts are arranged in a straight line, and the grinding belt grinds the contacts along the arrangement direction. When grinding the same part of multiple contacts, the same part on the grinding belt will continuously contact multiple contacts. As the grinding belt passes through each contact, the grinding effect at that point weakens, resulting in a weakening effect on the subsequent contacts. Ultimately, this leads to different processing effects for electrical contacts processed in the same batch. Summary of the Invention

By incorporating a circular processing table, a feeding structure, a grinding mechanism, and a synchronous rotation mechanism, the device fully utilizes the grinding surface, avoids over-grinding of some electrical contacts, and ensures the consistency and uniformity of electrical contact processing.

[0006] To address the problems of existing technologies, this invention provides a wear-resistant electrical contact processing device, comprising a circular processing table, a feeding structure for placing electrical contacts, a grinding mechanism, and a synchronous rotation mechanism; the edge of the circular processing table has several mounting grooves along its diameter; the feeding structure comprises several units, each set within one of the mounting grooves, and is movably connected to the circular processing table; the grinding mechanism is located at the upper end of the circular processing table, and includes a main shaft with one end extending downward through the center of the circular processing table and an annular grinding disc located at the other end of the main shaft and parallel to the circular processing table, and the main shaft is connected to the synchronous rotation mechanism; the synchronous rotation mechanism is located in the middle of the feeding structures, and is drively connected to the feeding structures.

[0007] Preferably, the feeding structure includes a limiting guide structure and a clamping structure; the limiting guide structure includes a movable block that can move along the diameter direction of the circular processing table, and a first rotating shaft is vertically arranged in the middle of the movable block, with the two ends of the first rotating shaft connected to the clamping structure and the synchronous rotation mechanism, respectively.

[0008] Preferably, the grinding mechanism further includes a first drive assembly for driving the moving block to move along the diameter direction of the circular processing table. The first drive assembly includes a drive ring body coaxially arranged and connected to the spindle. The circumferential wall of the drive ring body is alternately provided with a first protrusion and a second protrusion of different heights.

[0009] Preferably, the first drive assembly further includes a plurality of rollers, which are respectively mounted on a plurality of first rotating shafts, and the circumferential walls of the rollers abut against the circumferential walls of the drive ring.

[0010] Preferably, the limiting guide structure further includes a first guide component that provides a reset force to the moving block.

[0011] Preferably, the synchronous rotation mechanism includes a ring frame coaxially arranged with the main spindle and connected to the circular machining table, a second drive assembly, and several transmission structures; the second drive assembly is located in the middle of the ring frame and is connected to several transmission structures; the several transmission structures are respectively connected to the first rotating shaft in several limiting guide structures.

[0012] Preferably, the transmission structure includes a transmission component and a transmission maintenance structure; the two ends of the transmission component are respectively connected to the first rotating shaft and the second drive component; the transmission maintenance structure is disposed on one side of the transmission component and is used to maintain the transmission efficiency of the transmission component.

[0013] Preferably, the transmission holding structure includes a second guide rod disposed between the first rotating shaft and the second drive assembly and two clamping assemblies; both ends of the second guide rod extend to the outside of the transmission assembly; the two clamping assemblies are slidably connected to both ends of the second guide rod, respectively.

[0014] Preferably, the second drive assembly includes a central gear and several transmission gears; the central gear is coaxially arranged and fixedly connected to the main shaft; the several transmission gears are respectively arranged around the central gear, the transmission gears are connected to the transmission assembly, and the transmission gears mesh with the central gear.

[0015] The present invention also provides a processing method for an anti-wear electrical contact processing device, applicable to an anti-wear electrical contact processing device, comprising the following steps:

[0016] S1. Place multiple electrical contacts onto multiple clamping structures respectively;

[0017] S2. The rotation of the main shaft drives the annular grinding disc to rotate.

[0018] S3. The spindle simultaneously drives the first drive assembly to rotate around the axis of the spindle, and the first drive assembly drives the electrical contacts on the clamping structure to reciprocate along the diameter of the circular machining table.

[0019] S4. The main spindle also drives the synchronous rotation mechanism, which in turn drives the electrical contacts on the clamping structure to rotate.

[0020] The advantages of this invention compared to the prior art are:

[0021] 1. This invention comprises a circular processing table, a feeding structure, a grinding mechanism, and a synchronous rotation mechanism. The grinding mechanism's main shaft and annular grinding disc allow the rotating main shaft to drive the annular grinding disc to rotate, contacting and synchronously grinding multiple electrical contacts placed in the feeding structure. This ensures all electrical contacts are ground simultaneously, improving grinding efficiency. The synchronous rotation mechanism is connected to the feeding structure, allowing the rotating main shaft to drive each feeding component to rotate, which in turn causes the electrical contacts to rotate. The rotation of the electrical contacts combined with the rotation of the annular grinding disc creates a compound grinding action, significantly enhancing the grinding effect. This helps remove minor imperfections on the electrical contact surface, improving processing quality. Each feeding component reciprocates along the diameter of the circular processing table, causing the distance between the electrical contacts and the axis of the annular grinding disc to continuously change. This ensures the electrical contacts can contact different parts of the annular grinding disc, fully utilizing the grinding surface and preventing over-grinding of some electrical contacts, guaranteeing the consistency and uniformity of electrical contact processing.

[0022] 2. The present invention is equipped with a limiting guide structure and a clamping structure. In the grinding operation, if the electrical contact remains stationary, its contact surface will easily form a fixed grinding texture, affecting the processing quality. However, the synchronous rotation mechanism drives the first rotating shaft to rotate and uses the rigid connection between the clamping structure and the electrical contact to transmit the rotational power to the electrical contact, causing the electrical contact to rotate. The rotation of the electrical contact allows the electrical contact to contact the grinding disc in different postures, thereby effectively avoiding the formation of a fixed grinding texture and improving the smoothness and consistency of the processed surface of the electrical contact.

[0035] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figures 1 to 11 As shown: A wear-resistant electrical contact processing device includes a circular processing table 1, a feeding structure 2 for placing electrical contacts, a grinding mechanism 3, and a synchronous rotation mechanism 4. The circular processing table 1 has several mounting slots along its diameter along its edge. Several feeding structures 2 are respectively disposed within the several mounting slots and are movably connected to the circular processing table 1. The grinding mechanism 3 is located at the upper end of the circular processing table 1 and includes a main shaft 31 with one end extending downwards through the middle of the circular processing table 1 and an annular grinding disc 32 disposed at the other end of the main shaft 31 and parallel to the circular processing table 1. The main shaft 31 is connected to the synchronous rotation mechanism 4. The synchronous rotation mechanism 4 is located in the middle of the feeding structures 2 and is drively connected to the feeding structures 2.

[0037] When the processing flow starts, the operator first places multiple electrical contacts one by one into each feeding assembly, and then starts the processing equipment. After the grinding surface of the annular grinding disc 32 contacts all electrical contacts, the spindle 31 begins to rotate around its own axis, driving the annular grinding disc 32 to rotate and perform synchronous grinding operations on multiple electrical contacts. At the same time, the spindle 31 drives the synchronous rotation mechanism 4 to start, and the synchronous rotation mechanism 4 drives each feeding structure 2 to rotate. The rotation of the feeding structure 2 drives the rotation of the electrical contacts. The rotation of the electrical contacts and the revolution of the annular grinding disc 32 combine to significantly improve the grinding efficiency. In addition, each feeding structure 2 moves back and forth along the diameter of the circular processing table 1, so that the distance between the electrical contacts and the axis of the annular grinding disc 32 changes continuously, so that the electrical contacts can contact different parts of the annular grinding disc 32, thereby making full use of the grinding surface of the annular grinding disc 32, avoiding over-grinding of some electrical contacts, and ensuring the consistency and uniformity of the electrical contact processing.

[0038] Reference Figure 3 and Figure 4 As shown: The feeding structure 2 includes a limiting guide structure 21 and a clamping structure 22; the limiting guide structure 21 includes a moving block 211 that can move along the diameter of the circular processing table 1, and a first rotating shaft 212 is vertically arranged in the middle of the moving block 211. The two ends of the first rotating shaft 212 are respectively connected to the clamping structure 22 and the synchronous rotation mechanism 4.

[0039] The clamping structure 22 is existing technology. Its main function is to clamp and fix the electrical contact, ensuring a rigid connection between the electrical contact and the first rotating shaft 212. This stabilizes the position of the electrical contact during processing, effectively resists forces perpendicular to the axis of the first rotating shaft 212, and prevents the electrical contact from deviating from the axis during grinding. This ensures the accuracy and consistency of grinding. If the electrical contact remains stationary during grinding, a fixed grinding texture will form on its contact surface. Therefore, the synchronous rotation mechanism 4 drives the first rotating shaft 212 to rotate. The first rotating shaft 212 is rigidly connected to the electrical contact through the clamping structure 22, transmitting rotational power to the electrical contact and causing it to rotate. The rotation of the electrical contact, combined with the revolution of the annular grinding disc 32, allows the electrical contact to contact the grinding disc in different postures, improving the smoothness and consistency of the processed surface of the electrical contact and effectively preventing the formation of a fixed grinding texture on the contact surface.

[0040] Reference Figure 5 , Figure 6 and Figure 7As shown: The grinding mechanism 3 also includes a first drive assembly 33 for driving the moving block 211 to move along the diameter direction of the circular processing table 1. The first drive assembly 33 includes a drive ring body 331 coaxially arranged and connected to the spindle 31. The circumferential wall of the drive ring body 331 is alternately provided with a first protrusion 3311 and a second protrusion 3312 of non-equal height.

[0041] Specifically, the distance between the protrusion of the first protrusion 3311 and the drive ring 331 is smaller than the distance between the protrusion of the second protrusion 3312 and the drive ring 331. During the grinding operation, the rotation of the spindle 31 not only drives the annular grinding disc 32 to grind the electrical contacts, but also drives the operation of the first drive assembly 33. The drive ring 331 in the first drive assembly 33 rotates. During the rotation, the first protrusion 3311 and the second protrusion 3312 on the drive ring 331 will sequentially and continuously interact with the first rotating shaft. When the first protrusion 3311 contacts the first rotating shaft 212, the first rotating shaft 212 drives the moving block 211 to move a fixed distance in a specified direction. Subsequently, as the drive ring 331 continues to rotate, the second protrusion 3312 takes over from the first protrusion 3311 and contacts the first rotating shaft 212. The second protrusion 3312 drives the first rotating shaft 212 and the moving block 211 to move a distance in the same direction again, thereby realizing the movement of the feeding structure 2 along the diameter direction of the circular processing table 1.

[0042] Reference Figure 6 and Figure 7 As shown: the first drive assembly 33 also includes a plurality of rollers 332, which are respectively mounted on a plurality of first rotating shafts 212, and the circumferential wall of the rollers 332 abuts against the circumferential wall of the drive ring 331.

[0043] During the polishing of the electrical contacts, both sliding friction and rolling friction are generated between the drive ring 331 and the first rotating shaft 212. This compound friction mode increases the transmission resistance and reduces the smoothness of the movement of the first rotating shaft 212. Therefore, a roller 332 is installed on the first rotating shaft 212. The roller 332 does not rotate with the first rotating shaft 212 during operation, but rotates as a driven member following the rotation of the drive ring 331. This results in only rolling friction between the roller 332 and the drive ring 331. The resistance of rolling friction is small, thereby enabling the drive ring 331 to smoothly drive the first rotating shaft 212 to move.

[0044] Reference Figure 4 and Figure 8 As shown: The limiting guide structure 21 also includes a first guide component 213 that provides a reset force to the moving block 211.

[0045] Specifically, the first guide assembly 213 includes a plurality of first guide rods 2131, which are arranged in parallel to each other and are parallel to the axis of the circular processing table 1 in the direction of movement of the moving block 211. Each of the plurality of first guide rods 2131 is fitted with a first spring 2132 that applies a force to the moving block 211 toward the center of the circular processing table 1.

[0046] During operation, when the drive ring 331 drives the first rotating shaft 212 to move, its first protrusion 3311 and second protrusion 3312 can only apply a unidirectional driving force to the first rotating shaft 212, and cannot reset the first rotating shaft 212. Therefore, a first guide assembly 213 is provided. When the first rotating shaft 212 is pushed by the drive ring 331, the first rotating shaft 212 drives the moving block 211 to slide along several first guide rods 2131. The arrangement of several first guide rods 2131 ensures that the moving block 211 slides along several first guide rods 2131 during the movement. To ensure stability and prevent the moving block 211 from shifting, the moving block 211 compresses multiple first springs 2132 during its movement. These first springs 2132 are compressed synchronously and store elastic potential energy. As the first protrusion 3311 and the second protrusion 3312 on the drive ring 331 sequentially contact and switch with the first rotating shaft 212, the elastic potential energy stored in the first springs 2132 is released, pushing the moving block 211 toward the center of the drive ring 331, thereby realizing the reset function of the first rotating shaft 212 driving the electrical contacts.

[0047] Reference Figure 9 As shown: The synchronous rotation mechanism 4 includes an annular frame 41 coaxially arranged with the main spindle 31 and connected to the circular processing table 1, a second drive assembly 42 and several transmission structures; the second drive assembly 42 is located in the middle of the annular frame 41 and is connected to several transmission structures; the several transmission structures are respectively connected to the first rotating shaft 212 in several limiting guide structures 21.

[0048] Since there are many feeding structures 2, if the rotation of each feeding structure 2 is driven separately, a large number of drivers would be required, resulting in high processing equipment costs. Therefore, a ring frame 41, a second drive assembly 42, and several transmission structures are set up. The second drive assembly 42 is connected to the main shaft 31. In the working process, the rotation of the main shaft 31 is the key to driving the entire synchronous rotation mechanism 4. When the main shaft 31 starts to rotate, it will drive the second drive assembly 42 to move accordingly. Subsequently, the second drive assembly 42 uses its own driving force to synchronously drive the first rotating shaft 212 in multiple limit guide structures 21 to rotate through multiple transmission structures, so that multiple transmission structures can share a single drive source, effectively reducing the number of drivers, thereby significantly reducing the processing equipment cost, complexity, and maintenance costs.

[0049] Reference Figure 9 and Figure 10 As shown: The transmission structure includes a transmission component 43 and a transmission maintenance structure 44; the two ends of the transmission component 43 are respectively connected to the first rotating shaft 212 and the second drive component 42; the transmission maintenance structure 44 is disposed on one side of the transmission component 43 and is used to maintain the transmission efficiency of the transmission component 43.

[0050] Specifically, the transmission assembly 43 is a belt drive. The transmission assembly 43 includes a second rotating shaft 431, two transmission pulleys 432 and a transmission belt 433. The second rotating shaft 431 is arranged parallel to the first rotating shaft 212. One end of the second rotating shaft 431 is connected to the ring frame 41 through a bearing. The two transmission pulleys 432 are respectively installed on the first rotating shaft 212 and the second rotating shaft 431. The two ends of the transmission belt 433 are respectively sleeved on the two transmission pulleys 432 to form a closed transmission circuit.

[0051] The transmission assembly 43 adopts belt drive. In the working process, when the main shaft 31 drives the second drive assembly 42 to operate, the second drive assembly 42 drives the second rotating shaft 431 in the transmission assembly 43 to rotate around its axis. As the second rotating shaft 431 rotates, the transmission wheel 432 on the second rotating shaft 431 also rotates. Then, the rotational power is transmitted to the transmission wheel 432 on the first rotating shaft 212 through the transmission belt 433. Under the drive of the transmission belt 433, the transmission wheel 432 on the first rotating shaft 212 drives the first rotating shaft 212 to rotate around its axis. Through this transmission path, the rotation of the electric contact during the grinding process is finally realized, thereby meeting the process requirements of electric contact grinding.

[0052] Reference Figure 10 As shown: The transmission support structure 44 includes a second guide rod 441 and two clamping assemblies 442 disposed between the first rotating shaft 212 and the second drive assembly 42; both ends of the second guide rod 441 extend to the outside of the transmission assembly 43; the two clamping assemblies 442 are slidably connected to both ends of the second guide rod 441 respectively.

[0053] Specifically, the clamping assembly 442 includes a slider 4421, a clamping wheel 4422, and a second spring 4423. The slider 4421 is slidably connected to the second guide rod 441. The clamping wheel 4422 is mounted on the slider 4421, and the circumferential wall of the clamping wheel 4422 abuts against the transmission belt 433. The second spring 4423 is sleeved on the second guide rod 441, and the second spring 4423 continuously applies a force to the slider 4421 toward the middle of the transmission belt 433.

[0054] During operation, when the drive ring 331 drives the first rotating shaft 212 to move, the distance between the first rotating shaft 212 and the second rotating shaft 431 will continuously change. This will cause the tension of the transmission belt 433 between the two transmission wheels 432 to change accordingly. If the transmission belt 433 is loose, the rotational force transmitted from the second rotating shaft 431 to the first rotating shaft 212 will be weakened, affecting the transmission efficiency. Therefore, a second guide rod 441 and two clamping assemblies 442 are provided. The second spring 4423 in the clamping assembly 442 is always in a compressed state, which will apply a continuous force toward the middle of the second guide rod 441 to the slider 4421. This force is transmitted to the clamping wheel 442 through the slider 4421. 2. The clamping wheel 4422 presses the transmission belt 433 toward the center of the transmission belt 433 to maintain the tension of the transmission belt 433. When the distance between the two transmission wheels 432 changes, the second spring 4423 will extend or retract accordingly as needed to adjust the force exerted by the clamping wheel 4422 on the transmission belt 433. The tension adjustment effect of the clamping wheel 4422 on the transmission belt 433 ensures that the transmission effect between the transmission belt 433 and the two transmission wheels 432 remains stable no matter how the distance between the two transmission wheels 432 changes. This ensures that the first rotating shaft 212 can maintain a constant rotation effect during movement, meeting the requirements of the grinding process for rotational stability and continuity.

[0055] Reference Figure 9 and Figure 11 As shown: The second drive assembly 42 includes a central gear 421 and several transmission gears 422; the central gear 421 is coaxially arranged and fixedly connected to the main shaft 31; the several transmission gears 422 are respectively arranged around the central gear 421, the transmission gears 422 are connected to the transmission assembly 43, and the transmission gears 422 mesh with the central gear 421.

[0056] Specifically, several transmission gears 422 are respectively connected to the second rotating shafts 431 in several transmission components 43. In the working process, when the main shaft 31 starts to rotate, the rotational power of the main shaft 31 is transmitted to the central gear 421 through a fixed connection, causing the central gear 421 to rotate accordingly. Since the central gear 421 is meshed with several transmission gears 422, the rotation of the central gear 421 will drive several surrounding transmission gears 422 to rotate synchronously. Subsequently, each transmission gear 422 transmits the rotational power through its connected second rotating shaft 431. The power is delivered to the electrical contact mounted on the upper end of the second rotating shaft 431, causing the electrical contact to rotate. Due to the meshing relationship between the transmission gear 422 and the central gear 421, as well as the connection relationship between the transmission gear 422 and the second rotating shaft 431, the efficient and stable transmission of rotational power is ensured. At the same time, due to the parallel arrangement of multiple transmission gears 422 and transmission components 43, multiple electrical contacts can rotate simultaneously, and the synchronous rotation of the annular grinding disc 32 and the electrical contacts is also achieved, thereby meeting the requirements of the grinding process for the synchronous rotation of the annular grinding disc 32 and the electrical contacts.

[0057] A method for processing an anti-wear electrical contact processing device, applicable to an anti-wear electrical contact processing device, includes the following steps:

[0058] S1. Place multiple electrical contacts onto multiple clamping structures 22 respectively;

[0059] S2, The rotation of the main shaft 31 drives the annular grinding disc 32 to rotate;

[0060] S3, the spindle 31 simultaneously drives the first drive assembly 33 to rotate around the axis of the spindle 31, and the first drive assembly 33 drives the electrical contacts on the clamping structure 22 to reciprocate along the diameter direction of the circular processing table 1.

[0061] S4, the main shaft 31 also drives the synchronous rotation mechanism 4 to operate, and the synchronous rotation mechanism 4 drives the electrical contacts on the clamping structure 22 to rotate.

[0062] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
