Description

Technical Field

[0001] The present invention relates to the technical field of electric contact processing, in particular to a wear-resistant electric contact processing device, and also to a processing method of the wear-resistant electric contact processing device. Background Art

[0002] In the fields of power, electronics and automation control, electrical contacts are key components, and their performance and quality are directly related to the stability and reliability of the entire system. Electrical contacts need to withstand frequent connection and disconnection operations during use, so their surface quality and wear resistance are crucial. Traditional electrical contact processing methods often use manual or simple mechanized grinding, which is not only inefficient, but also difficult to ensure the consistency and uniformity of grinding, which can easily lead to uneven wear on the surface of the electrical contacts, increased contact resistance, and other problems, thereby affecting their service life and performance.

[0003] In the prior art, for example, a Chinese utility model patent with authorization announcement number CN222134497U discloses a rivet-type electric contact convex point processing equipment, whose working process is: first, the electric contact body is placed in the circular groove on the top of the rotating column for fixing, and then the grinding belt is brought into contact with the position of the electric contact body that needs to be polished, so as to use the grinding belt to polish the electric contact, and the electric contact body is evenly inserted on each rotating column, and all the rotating columns are arranged in a straight line, so the grinding belt can be in contact with multiple electric contact bodies for grinding at the same time, and the rotating column can be rotated, and the sliding rod used to install the grinding belt can be rotated and slid by the connecting rod, so that different positions of the electric contact body can be polished, which is convenient for batch processing of the convex points of the electric contact body and improves work efficiency.

DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Reference Figures 1 to 11 As shown: an electric contact processing equipment for preventing wear, comprising a circular processing table 1, a feeding structure 2 for placing electric contacts, a grinding mechanism 3 and a synchronous rotation mechanism 4; a plurality of mounting grooves are provided on the edge of the circular processing table 1 along the diameter direction; there are a plurality of feeding structures 2, and the plurality of feeding structures 2 are respectively arranged in the plurality of mounting grooves, and the feeding structure 2 is movably connected with the circular processing table 1; the grinding mechanism 3 is arranged at the upper end of the circular processing table 1, and the grinding mechanism 3 comprises a main shaft 31 with one end passing downward through the middle of the circular processing table 1 and an annular grinding disc 32 arranged at the other end of the main shaft 31 and parallel to the circular processing table 1, and the main shaft 31 is connected with the synchronous rotation mechanism 4; the synchronous rotation mechanism 4 is arranged in the middle of the plurality of feeding structures 2, and the synchronous rotation mechanism 4 is transmission-connected with the plurality of feeding structures 2.

[0037] When the processing flow starts, the operator first places multiple electrical contacts in each discharge component one by one, and then starts the processing equipment. After the grinding surface of the annular grinding disk 32 contacts all the electrical contacts, the main shaft 31 starts to rotate around its own axis, driving the annular grinding disk 32 to rotate, and performing synchronous grinding operations on multiple electrical contacts. At the same time, the main shaft 31 drives the synchronous rotation mechanism 4 to start, and the synchronous rotation mechanism 4 drives each discharge structure 2 to rotate. The rotation of the discharge structure 2 drives the self-rotation of the electric contact. The self-rotation of the electric contact is combined with the revolution of the annular grinding disk 32, which significantly improves the grinding efficiency. In addition, each discharge structure 2 reciprocates along the diameter direction of the circular processing table 1, so that the distance between the electric contact and the axis of the annular grinding disk 32 changes continuously, so that the electric contact can contact different parts of the annular grinding disk 32, thereby fully utilizing the grinding surface of the annular grinding disk 32, avoiding excessive grinding of some electric contacts, and ensuring the consistency and uniformity of the electric contact processing.

[0038] Reference Figure 3 and Figure 4 As shown: the discharge 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 direction of the circular processing table 1, and a first rotating shaft 212 is vertically arranged in the middle of the moving block 211, and both 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 a prior art. The main function of the clamping structure 22 is to clamp and fix the electric contact, ensure a rigid connection between the electric contact and the first rotating shaft 212, stabilize the position of the electric contact during the processing, effectively resist the force perpendicular to the axial direction of the first rotating shaft 212, avoid the electric contact from deviating from the axial movement during the grinding process, and ensure the accuracy and consistency of the grinding. During the grinding operation, if the electric contact remains stationary and does not rotate, the contact surface of the electric contact will form a fixed grinding texture. To this end, the synchronous rotating mechanism 4 drives the first rotating shaft 212 to rotate. The first rotating shaft 212 is rigidly connected to the electric contact through the clamping structure 22, and the rotational power is transmitted to the electric contact, prompting the electric contact to rotate. The rotation of the electric contact, combined with the revolution of the annular grinding disk 32, enables the electric contact to contact the grinding disk in different postures, thereby improving the smoothness and consistency of the processed surface of the electric contact, thereby effectively preventing the contact surface of the electric contact from forming a fixed grinding texture.

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

[0041] Specifically, the distance between the protrusion of the first protrusion 3311 and the driving ring body 331 is smaller than the distance between the protrusion of the second protrusion 3312 and the driving ring body 331. During the grinding operation, the rotation of the main shaft 31 not only drives the annular grinding disc 32 to grind the electrical contact, but also drives the operation of the first driving assembly 33. The driving ring body 331 in the first driving assembly 33 rotates. During the rotation process, the first protrusion 3311 and the second protrusion 3312 on the driving ring body 331 will sequentially and continuously rotate with the first rotating shaft 212 comes into contact. 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 along the specified direction. Subsequently, as the driving ring body 331 continues to rotate, the second protrusion 3312 replaces the first protrusion 3311 to contact the first rotating shaft 212, and 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 driving the discharge structure 2 to move along the diameter direction of the circular processing table 1.

[0042] Reference Figure 6 and Figure 7 As shown, the first driving assembly 33 further includes a plurality of rollers 332 , which are respectively mounted on a plurality of first rotating shafts 212 , and the circumferential walls of the rollers 332 are tightly pressed against the circumferential wall of the driving ring body 331 .

[0043] During the process of grinding the electric contacts, both sliding friction and rolling friction are generated between the driving ring body 331 and the first rotating shaft 212. This composite 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. During operation, the roller 332 does not rotate with the first rotating shaft 212, but rotates as a follower following the rotation of the driving ring body 331, so that only rolling friction is generated between the roller 332 and the driving ring body 331, and the resistance of the rolling friction is small, so that the driving ring body 331 can 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 for providing a restoring force to the moving block 211 .

[0045] Specifically, the first guide assembly 213 includes a plurality of first guide rods 2131, which are arranged parallel to each other, and the first guide rods 2131 are parallel to the axis of the circular processing table 1 where the movement direction of the moving block 211 is located, and the plurality of first guide rods 2131 are each provided with a first spring 2132 for applying a force to the moving block 211 toward the middle of the circular processing table 1.

[0046] During operation, when the driving ring body 331 drives the first rotating shaft 212 to move, the first protrusion 3311 and the second protrusion 3312 thereon can only apply a unidirectional driving force to the first rotating shaft 212, and cannot achieve the reset of the first rotating shaft 212. Therefore, a first guide assembly 213 is provided. When the first rotating shaft 212 is pushed by the driving ring body 331, the first rotating shaft 212 drives the moving block 211 to slide along the plurality of first guide rods 2131. The provision of the plurality of first guide rods 2131 ensures that the moving block 211 is in the process of movement. The stability of the moving block 211 is prevented from being offset. At the same time, the moving block 211 will compress multiple first springs 2132 during the movement. These first springs 2132 are synchronously compressed and store elastic potential energy. As the first protrusion 3311 and the second protrusion 3312 on the driving ring body 331 contact and switch with the first rotating shaft 212 in sequence, the elastic potential energy stored in the first spring 2132 is released, pushing the moving block 211 to move toward the center of the driving ring body 331, thereby realizing the reset function of the first rotating shaft 212 driving the electrical contact.

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

[0048] Since there are many discharge structures 2, if the rotation of each discharge structure 2 is driven separately, more drivers are required, resulting in higher cost of the processing equipment. Therefore, a ring frame 41, a second drive component 42 and several transmission structures are set. The second drive component 42 is connected to the main shaft 31 in transmission. 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, the main shaft 31 will drive the second drive component 42 to move accordingly. Subsequently, the second drive component 42 uses its own driving force to synchronously drive the first rotating shaft 212 in the multiple limiting guide structures 21 to rotate through multiple transmission structures, so that multiple transmission structures can share a driving source, effectively reducing the number of drivers, thereby significantly reducing the cost of processing equipment, reducing the complexity of the equipment and maintenance costs.

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

[0050] Specifically, the transmission assembly 43 is a belt transmission, and the transmission assembly 43 includes a second rotating shaft 431, two transmission wheels 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 annular frame 41 through a bearing, the two transmission wheels 432 are respectively installed on the first rotating shaft 212 and the second rotating shaft 431, and the two ends of the transmission belt 433 are respectively mounted on the two transmission wheels 432 to form a closed transmission loop.

[0051] The transmission component 43 adopts belt transmission. In the working process, when the main shaft 31 drives the second driving component 42 to operate, the second driving component 42 drives the second rotating shaft 431 in the transmission component 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 accordingly, and then the rotational power is transmitted to the transmission wheel 432 on the first rotating shaft 212 through the transmission belt 433. The transmission wheel 432 on the first rotating shaft 212 is driven by the transmission belt 433 to drive 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 the grinding of the electric contact.

[0052] Reference Fig.10 As shown: the transmission maintaining structure 44 includes a second guide rod 441 and two clamping assemblies 442 arranged between the first rotating shaft 212 and the second driving 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 respectively slidably connected to both ends of the second guide rod 441.

[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 installed on the slider 4421, and the circumferential wall of the clamping wheel 4422 is pressed 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 driving ring body 331 drives the first rotating shaft 212 to move, the distance between the first rotating shaft 212 and the second rotating shaft 431 will change continuously, which 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, and 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 squeezes the transmission belt 433 toward the middle 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 be extended and retracted accordingly as needed to adjust the force of the clamping wheel 4422 on the transmission belt 433. The tensioning adjustment effect of the clamping wheel 4422 on the transmission belt 433 ensures that no matter how the distance between the two transmission wheels 432 changes, the transmission effect between the transmission belt 433 and the two transmission wheels 432 can remain stable, thereby achieving the first rotating shaft 212 can maintain the rotation effect unchanged during the movement, meeting the requirements of the grinding process for rotation stability and continuity.

[0055] Reference Fig. 9 and Fig.11 As shown: the second driving assembly 42 includes a central gear 421 and a plurality of transmission gears 422; the central gear 421 is coaxially arranged with the main shaft 31 and fixedly connected; the plurality of transmission gears 422 are respectively arranged around the central gear 421, the transmission gear 422 is connected to the transmission assembly 43, and the transmission gear 422 is meshed with the central gear 421.

[0056] Specifically, a plurality of transmission gears 422 are respectively connected to the second rotating shafts 431 in the plurality of transmission assemblies 43. In the working process, when the main shaft 31 starts to rotate, the power of the rotation of the main shaft 31 is transmitted to the central gear 421 through the fixed connection, so that the central gear 421 rotates accordingly. Since the central gear 421 is meshed with the plurality of transmission gears 422, the rotation of the central gear 421 drives the plurality of transmission gears 422 around to rotate synchronously. Subsequently, each transmission gear 422 transmits the rotation power to the central gear 421 through the second rotating shaft 431 connected thereto. The electric contact installed on the upper end of the second rotating shaft 431 is handed over to the electric contact to rotate. Due to the meshing relationship between the transmission gear 422 and the center gear 421 and the connection relationship between the transmission gear 422 and the second rotating shaft 431, the efficient and stable transmission of the rotational power is ensured. At the same time, due to the parallel arrangement of multiple transmission gears 422 and transmission components 43, multiple electric contacts can rotate at the same time, and the synchronous rotation of the annular grinding disc 32 and the electric contacts is also realized, thereby meeting the requirements of the grinding process for the synchronization of the rotation of the annular grinding disc 32 and the electric contacts.

[0058] S1, placing a plurality of electrical contacts into a plurality of clamping structures 22 respectively;

[0059] S2, the main shaft 31 rotates to drive the annular grinding disc 32 to rotate;

[0060] S3, the spindle 31 drives the first drive assembly 33 to rotate around the axis of the spindle 31 at the same time, and the first drive assembly 33 drives the electric contact 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 electric contacts on the clamping structure 22 to rotate.

[0062] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
