Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a grinding equipment with an electrostatic contact. Background Technology

[0002] In the field of electrical equipment manufacturing, electrostatic contacts are key components, and their surface precision and processing quality directly affect the conductivity, contact reliability, and service life of the equipment. As power systems develop towards higher voltage and higher current, more stringent requirements are placed on the grinding of electrostatic contacts, which must simultaneously meet the grinding needs of different postures of the ends and the body to adapt to the stability of electrical connections under complex working conditions.

[0003] Traditional electrostatic contact grinding devices have significant limitations: On the one hand, most devices can only process a single part of the contact (such as the body or end). If it is necessary to switch grinding areas, the contact clamping angle and position need to be adjusted frequently by hand, which is cumbersome and prone to introducing clamping errors, making it difficult to control the processing accuracy. On the other hand, existing devices lack flexibility in clamping and fixing the contacts, making it difficult to adapt to contacts of different specifications and sizes. Moreover, during posture switching, it is impossible to accurately achieve specific grinding postures such as end-tilting and body-leveling, which affects grinding efficiency and surface quality consistency. Utility Model Content

[0004] This invention provides a grinding device for electrostatic contacts, which solves the problem that existing devices are not easy to grind the entire electrostatic contact in one clamping.

[0005] To alleviate the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A grinding device for an electrostatic contact includes a grinding table, a fixed base mounted on the grinding table, a first fixed frame and a second fixed frame slidably connected to the upper part of the fixed base, and a cylinder connected between the first fixed frame and the second fixed frame.

[0007] The electrostatic contact is rotatably connected between the first fixed frame and the second fixed frame. A first slide rod and a second slide rod are respectively fixedly connected to the first fixed frame and the second fixed frame. A sliding groove is provided on the fixed base. The sliding groove is composed of a first horizontal section, a raised horizontal section and a second horizontal section. When the first slide rod slides in the first horizontal section and the second slide rod slides in the raised horizontal section, the electrostatic contact can be tilted upward to perform end grinding. When the second slide rod slides in the second horizontal section, the electrostatic contact can be axially horizontal to perform body grinding.

[0008] Furthermore, the main body of the electrostatic contact is cylindrical and the end is conical, with an angle α between the sidewall of the main body and the sidewall of the end, and an upward tilt angle of the electrostatic contact of α.

[0009] Furthermore, fixed cones are rotatably connected to the opposite surfaces of the first fixed frame and the second fixed frame. The two fixed cones are coaxially arranged. When the cylinder shortens, the two fixed cones are respectively inserted into the holes at both ends of the electrostatic contact, thereby fixing the electrostatic contact.

[0010] Furthermore, a first motor is fixedly connected to the first fixed frame or the second fixed frame, and the fixed cone near the first motor is fixedly connected to the output end of the first motor.

[0011] Furthermore, four hydraulic rods are fixedly connected to the grinding table, and the output ends of the four hydraulic rods are respectively fixedly connected to the four corners of the fixed base.

[0012] Furthermore, a grinding disc is rotatably connected to the grinding table on a fixed axis.

[0013] Furthermore, a second motor is installed on the grinding table, and the grinding disc is fixedly connected to the output end of the second motor.

[0014] Furthermore, a base is fixedly connected to the grinding table, and the second motor is fixedly connected to the base.

[0015] Furthermore, a cover is rotatably connected to the base, and the cover is fastened to the upper part of the grinding disc.

[0016] Furthermore, a rotating shaft is fixedly connected to the base, and the end of the rotating shaft is fixedly connected to the cover.

[0017] The beneficial effects of this utility model are analyzed as follows:

[0018] A grinding device for an electrostatic contact includes a grinding table with a fixed base mounted on it. A first fixed frame and a second fixed frame are slidably connected to the upper part of the fixed base, and a cylinder is connected between the first fixed frame and the second fixed frame. The electrostatic contact is rotatably connected between the first fixed frame and the second fixed frame. A first slide rod and a second slide rod are respectively fixedly connected to the first fixed frame and the second fixed frame. A sliding groove is provided on the fixed base, which consists of a first horizontal section, a raised horizontal section, and a second horizontal section. When the first slide rod slides in the first horizontal section and the second slide rod slides in the raised horizontal section, the electrostatic contact head is tilted upwards for end grinding. When the second slide rod slides in the second horizontal section, the electrostatic contact head is axially horizontal for body grinding.

[0019] After the cylinder extends, the electrostatic contact to be ground is placed between the first and second fixed frames. Then, the cylinder is shortened to clamp and fix the electrostatic contact. Subsequently, the first fixed frame is pushed so that the second fixed frame can move synchronously. During the movement, both the first and second slide rods slide in the slide groove. The first slide rod always slides in the first horizontal section of the slide groove, and the second slide rod slides from the first horizontal section to the raised horizontal section. At this time, the second fixed frame rises, causing the electrostatic contact to tilt upwards, allowing its end to be ground. As the first fixed frame moves, the second slide rod can slide in the second horizontal section. At this time, the electrostatic contact is in an axially horizontal state, allowing the body of the electrostatic contact to be ground. Attached Figure Description

[0032] like Figures 1-6 As shown, a grinding device for an electrostatic contact includes a grinding table 100, on which a fixed base 200 is mounted. A first fixed frame 220 and a second fixed frame 230 are slidably connected to the upper part of the fixed base 200. A cylinder 240 is connected between the first fixed frame 220 and the second fixed frame 230. The electrostatic contact is rotatably connected between the first fixed frame 220 and the second fixed frame 230. A first slide rod 250 and a second slide rod 251 are respectively fixedly connected to the first fixed frame 220 and the second fixed frame 230. A sliding groove 280 is provided on the fixed base 200. The sliding groove 280 is composed of a first horizontal section 281, a raised horizontal section 282, and a second horizontal section 283. When the first slide rod 250 slides on the first horizontal section 281 and the second slide rod 251 slides on the raised horizontal section 282, the electrostatic contact is tilted upwards to perform end grinding. When the second slide rod 251 slides on the second horizontal section 283, the electrostatic contact is axially horizontal to perform body grinding.

[0033] The working mechanism of the electrostatic contact grinding device provided in this embodiment is as follows:

[0034] After the control cylinder 240 extends, the static contact to be ground is placed between the first fixed frame 220 and the second fixed frame 230. Then, the control cylinder 240 is shortened to clamp and fix the static contact. Subsequently, the first fixed frame 220 is pushed so that the second fixed frame 230 can move synchronously. During the movement, the first slide rod 250 and the second slide rod 251 slide within the slide groove 280. The first slide rod 250 always slides within the first horizontal section 281 of the slide groove 280, and the second slide rod 251 slides from the first horizontal section 281 to the raised horizontal section 282. At this time, the second fixed frame 230 is raised, so the static contact is tilted up, allowing its end to be ground. As the first fixed frame 220 moves, the second slide rod 251 can slide within the second horizontal section 283. At this time, the static contact is in an axially horizontal state, and the body of the static contact can be ground.

[0035] Inclined sections are provided for transition between the first horizontal section 281 and the raised horizontal section 282, as well as between the raised horizontal section 282 and the second horizontal section 283.

[0036] Among the optional methods in this embodiment, the more preferred one is:

[0037] The main body of the electrostatic contact is cylindrical and the end is conical. The angle between the side wall of the main body and the side wall of the end is α, and the upward angle of the electrostatic contact is α.

[0038] The angle after the electrostatic contact is tilted upward is α. At this time, the end face of the electrostatic contact can be polished without changing the angle of the polishing disc 130°.

[0039] Among the optional methods in this embodiment, the more preferred one is:

[0040] Fixed cones 260 are rotatably connected to the opposite surfaces of the first fixed frame 220 and the second fixed frame 230. The two fixed cones 260 are coaxially arranged. When the cylinder 240 is shortened, the two fixed cones 260 are respectively inserted into the holes at both ends of the electrostatic contact, thereby fixing the electrostatic contact.

[0041] The fixing cone 260 is made of rubber or a material with a hardness lower than that of the electrostatic contact to ensure that the electrostatic contact will not be damaged by impact. After the electrostatic contact is placed between the first fixing frame 220 and the second fixing frame 230, the control cylinder 240 is shortened. At this time, the two fixing cones 260 can be inserted into the round holes at both ends of the electrostatic contact, thereby clamping and fixing the electrostatic contact.

[0042] Among the optional methods in this embodiment, the more preferred one is:

[0043] A first motor 270 is fixedly connected to the first fixed frame 220 or the second fixed frame 230, and a fixed cone 260 near the first motor 270 is fixedly connected to the output end of the first motor 270.

[0044] The first motor 270 drives any one of the fixed cones 260 to rotate, thereby causing the other fixed cone 260 to also rotate. At this time, the electrostatic contact is driven to rotate. The direction of rotation of the electrostatic contact is opposite to that of the grinding disc 130, ensuring the grinding effect on the electrostatic contact.

[0045] Among the optional methods in this embodiment, the more preferred one is:

[0046] Four hydraulic rods 210 are fixedly connected to the grinding table 100, and the output ends of the four hydraulic rods 210 are fixedly connected to the four corners of the fixed base 200 respectively.

[0047] By controlling the synchronous extension and retraction of the four hydraulic rods 210, the fixed base 200 can be raised and lowered smoothly. By controlling the raising and lowering of the fixed base 200, the degree of abrasion on the electrostatic contact can be controlled. In addition, by controlling the raising and lowering of the fixed base 200, the wear of the grinding disc 130 can also be compensated.

[0048] Among the optional methods in this embodiment, the more preferred one is:

[0049] A grinding disc 130 is fixedly connected to the grinding table 100.

[0050] The polishing disc 130 is located on the upper part of the electrostatic contact and is used to polish the electrostatic contact.

[0051] Among the optional methods in this embodiment, the more preferred one is:

[0052] A second motor 120 is installed on the grinding table 100, and the grinding disc 130 is fixedly connected to the output end of the second motor 120.

[0053] The second motor 120 is used to drive the grinding disc 130 to rotate.

[0054] Among the optional methods in this embodiment, the more preferred one is:

[0055] A base 110 is fixedly connected to the grinding table 100, and a second motor 120 is fixedly connected to the base 110.

[0056] The base 110 provides mounting support for the second motor 120.

[0057] Among the optional methods in this embodiment, the more preferred one is:

[0058] A cover 140 is rotatably connected to the base 110, and the cover 140 is fastened to the upper part of the grinding disc 130.

[0059] During grinding, the cover 140 is placed on the grinding disc 130 to suppress the amount of metal chips flying during grinding.

[0060] Among the optional methods in this embodiment, the more preferred one is:

[0061] A rotating shaft 150 is fixedly connected to the base 110, and the end of the rotating shaft 150 is fixedly connected to the cover 140.

[0062] The cover 140 is rotatably connected to the base 110 via a pivot 150. Manually flipping the cover 140 allows it to rotate around the pivot 150, facilitating the replacement of the grinding disc 130.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
