Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a carbon brush holder. Background Technology

[0002] Coil forming equipment is a key process in copper tube forming. Its core working component, the drum, and the supporting electrical control equipment need to rotate synchronously to complete the production operation. To ensure the stable operation of the electrical control equipment during rotation, a slip ring and brush holder assembly is usually installed above the drum. The transmission of electrical energy and signals is achieved through the sliding contact between the carbon brush and the slip ring. This assembly is an important link in ensuring the continuous and reliable operation of the coil forming equipment.

[0003] The carbon brush holders in the currently used brush holder assemblies have poor short-circuit protection capabilities. The carbon brush holders cannot accurately adjust the contact position between the carbon brush and the slip ring according to the actual working conditions. Problems such as the brush holder rotating along with the fixing bolts or automatically rotating during equipment operation and vibration directly lead to the inability of the carbon brush and slip ring to achieve precise engagement. This can result in poor contact affecting equipment operating efficiency, or even complete disengagement of the carbon brush and slip ring, which not only disrupts the normal production process but may also pose a serious threat to personal safety during production. Summary of the Invention

[0004] The purpose of this invention is to provide a carbon brush holder with a height adjustment function to ensure stable cooperation between the carbon brush and the slip ring.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A carbon brush holder includes: a base, the base having a base connection hole and a base fine adjustment hole; a fixing plate, the lower part of the fixing plate having a fixing plate fine adjustment hole, the fixing plate fine adjustment hole including a strip hole or a plurality of circular holes spaced apart along the vertical direction; and a fine adjustment bolt, the fine adjustment bolt passing through the fixing plate fine adjustment hole and connecting to the base fine adjustment hole of the base, the end of the fine adjustment bolt abutting against the fixing plate.

[0006] In the above technical solution, a carbon brush holder is formed by a base and a fixing plate. The brush holder can be directly fixedly mounted on the fixing plate, and the carbon brushes are fixed on the brush holder. A fine-tuning bolt connects the fixing plate to the base, and the fine-tuning bolt engages with the fine-tuning hole on the fixing plate to achieve fine-tuning of the carbon brush holder's height. Specifically, during fine-tuning, the operator removes the fine-tuning bolt, adjusts the height of the fixing plate according to the required carbon brush position, and after determining the height of the fixing plate, passes the fine-tuning bolt through the fine-tuning hole on the fixing plate and connects it to the base to fix the carbon brushes at the required height, which is more conducive to the contact between the carbon brushes and the slip ring.

[0007] Furthermore, the fixing plate has a threaded hole on one side, and the base has an elongated hole. The fixing bolt passes through the elongated hole and is threadedly connected to the threaded hole of the fixing plate. The end of the fixing bolt abuts against the base.

[0008] Furthermore, the axis of the threaded hole in the fixing plate is set perpendicular to the axis of the connecting hole in the base.

[0009] Furthermore, a brush holder mounting plate is fixedly installed on one side of the fixing plate.

[0010] Furthermore, a side panel is fixedly installed on one side of the fixing plate, and the brush holder mounting plate and the side panel are respectively set on both sides of the fixing plate.

[0011] Furthermore, the brush holder mounting plate has a brush holder groove that mates with the fixing plate, and the side panel has a side panel groove that mates with the fixing plate.

[0012] Furthermore, both ends of the fixing plate are provided with positioning threaded holes, both ends of the brush holder mounting plate are provided with first positioning holes, and both ends of the side panel are provided with second positioning holes. The first positioning bolt passes through the first positioning hole and is connected to the positioning threaded hole of the fixing plate, and the second positioning bolt passes through the second positioning hole and is connected to the positioning threaded hole of the fixing plate.

[0013] Furthermore, the brush holder mounting plate is provided with several square slots for mounting the brush holder, the brush holder mounting plate is provided with mounting holes corresponding to the square slots, the side panel is provided with clearance holes corresponding to the mounting holes, the fixing plate is provided with a slot along the length direction, and the mounting bolts pass through the mounting holes, the slots and the clearance holes and are connected to the nuts.

[0014] Furthermore, the mounting bolts are square head bolts or hexagonal bolts.

[0015] Furthermore, the width of the slot is greater than the diameter of the mounting bolt.

[0016] In summary, this utility model has the following beneficial effects: (1) This utility model provides a fixing plate with a fixing plate fine adjustment hole, which enables fine adjustment of the height of the entire carbon brush bracket, making it easier for the carbon brush and slip ring to fit together precisely. (2) The present invention provides a square groove for the brush holder on the brush holder fixing plate. During use, the brush holder will not rotate with the shaking of the fixing bolts and the equipment, reducing the frequency of problems such as poor contact or failure to contact. (3) The brush holder groove of the brush holder fixing plate and the side panel groove provided in the side panel are positioned by positioning holes. Combined with the mounting holes provided in the square groove, the clearance holes provided in the side panel, and the slots provided in the fixing plate, the insulation effect can be directly achieved, reducing the frequency of short circuits. (4) The bolts for fixing the brush holder in this utility model are square head bolts. Preferably, the directional bolts are square head bolts. The size of the square head of the square head bolt is just right to fit into the groove of the brush holder, which plays a fixing role for the bolts. It can also be tightened more tightly when connecting the carbon brush wires, and it is not easy to loosen. Attached Figure Description

These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0023] like Figure 1-5 As shown, a carbon brush holder includes: a base 9, which has a base connection hole 92 and a base fine adjustment hole 91; a fixing plate 1, the lower part of which has a fixing plate fine adjustment hole, which includes a strip hole or a plurality of circular holes 12 arranged at intervals along the vertical direction; and a fine adjustment bolt 10, which passes through the fixing plate fine adjustment hole and is connected to the base fine adjustment hole 91 of the base 9, with the end of the fine adjustment bolt 10 abutting against the fixing plate.

[0024] In the above technical solution, a carbon brush holder is formed by a base and a fixing plate. The brush holder can be directly fixedly mounted on the fixing plate, and the carbon brushes are fixed on the brush holder. The fixing plate is connected to the base by a fine-tuning bolt, which engages with the fine-tuning holes on the fixing plate to achieve fine-tuning of the height of the carbon brush holder.

[0025] Specifically, during fine-tuning, the operator removes the fine-tuning bolts, adjusts the height of the fixing plate according to the required position of the carbon brush, and after the height of the fixing plate is determined, the fine-tuning bolts are passed through the fine-tuning holes of the fixing plate and connected to the base to fix the carbon brush at the required height, which is more conducive to the contact between the carbon brush and the slip ring.

[0026] It should be further explained that the base connection hole 92 is a countersunk hexagonal head hole, and the base fine adjustment hole 91 is a threaded hole. The fine adjustment bolt 10 passes through the round hole 12 and is directly threaded into the base fine adjustment hole 91 of the base. The fine adjustment bolt can be a shoulder bolt.

[0027] It should be further explained that the fixing plate fine-tuning holes include strip-shaped holes, which can be one, two, or even more. The fixing plate fine-tuning holes also include several circular holes arranged at intervals along the vertical direction, with at least two circular holes, to achieve fine-tuning of the fixing plate. Of course, the fixing plate fine-tuning holes can be a combination of strip-shaped holes and circular holes; for example, two fixing plate fine-tuning holes and a circular hole positioned between two fixing plate fine-tuning holes are all within the scope of protection of this application.

[0028] Specifically, such as Figure 2 As shown, the fixing plate 1 has four round holes 12 to facilitate precise alignment of the slip ring during installation. The base connection hole can be a countersunk bolt hole.

[0029] During implementation, the fixing plate 1 has a threaded hole 94 on one side, and the base 9 has an elongated hole 95. The fixing bolt 8 passes through the elongated hole 95 and is threadedly connected to the threaded hole 94 on the fixing plate, with the end of the fixing bolt 8 abutting against the base 9. In actual installation, after the height of the fixing plate is adjusted to the correct position, the fixing bolt passes through the elongated hole on the base and is threadedly connected to the threaded hole on the fixing plate, with its end abutting against the base, further enhancing the effective fixation between the fixing plate and the base. When it is necessary to fine-tune the position of the fixing plate, the fixing bolt and the fine-tuning bolt can be removed to adjust the height of the fixing plate. The use of fixing bolts, threaded holes, and elongated holes on the base effectively reduces the loosening or displacement of the support due to vibration and other factors during equipment operation, ensuring the reliable operation of the carbon brush support under complex working conditions.

[0030] As a preferred option, the fixing plate 1 is made of stainless steel, which maintains good corrosion resistance and high strength in oily environments, and provides sufficient support.

[0031] During implementation, the axis of the threaded hole 94 on the fixing plate is perpendicular to the axis of the fine-tuning hole 91 on the base. This allows for a more stable installation of the fixing plate. During equipment operation, the carbon brush holder is subjected to forces from various directions. By ensuring the axis of the threaded hole on the fixing plate is perpendicular to the axis of the connecting hole on the base, the load-bearing capacity of the carbon brush holder is improved, thereby enhancing its stability and durability.

[0032] During implementation, a brush holder mounting plate 2 is fixedly installed on one side of the fixing plate 1. The brush holder mounting plate is fixed to one side of the fixing plate, providing a positioning reference for the installation of the brush holder and facilitating the installation and removal of the brush holder.

[0033] During implementation, a side panel 7 is fixedly installed on one side of the fixing plate 1. This enhances the overall structural strength of the carbon brush holder and improves its stability.

[0034] In implementation, the brush holder mounting plate 2 has a brush holder groove 21 that mates with the fixing plate 1, and the side panel 7 has a side panel groove 22 that mates with the fixing plate 1. The brush holder mounting plate and the side panel are connected to the fixing plate through the brush holder groove and the side panel groove, respectively, enhancing the stability of the carbon brush holder and effectively reducing vibration and displacement caused by loose connections. This tightly fitted structure can also improve the insulation performance of the holder to a certain extent, reducing the frequency of short circuits and other faults, and ensuring the safe and reliable operation of the equipment.

[0035] In implementation, both ends of the fixing plate 1 are provided with positioning threaded holes 14, both ends of the brush holder mounting plate 2 are provided with first positioning holes 11, and both ends of the side panel 7 are provided with second positioning holes 13. The first positioning bolt 3 passes through the first positioning hole 11 and connects to the positioning threaded hole of the fixing plate 1, and the second positioning bolt 15 passes through the second positioning hole 13 and connects to the positioning threaded hole of the fixing plate 1. When connecting the brush holder mounting plate and the side panel to the fixing plate, the connection is achieved through the first positioning bolt and the second positioning bolt, which is stable and reliable. It should be noted that the positioning threaded hole can be a through threaded hole, with its two ends connected to the first positioning bolt and the second positioning bolt respectively; of course, the positioning bolt hole can be two blind holes, connected to the first positioning bolt and the second positioning bolt respectively, with the two blind holes coaxially arranged and opening in opposite directions.

[0036] In practice, the brush holder mounting plate 2 is provided with several square slots 16 for mounting the brush holder 5. The square slots facilitate the installation of the brush holder 5. The brush holder mounting plate 2 is provided with mounting holes 17 corresponding to the square slots. The side panel is provided with clearance holes 18 corresponding to the mounting holes. The fixing plate is provided with slots 19 along the length direction. The mounting bolts 6 pass through the mounting holes, slots and clearance holes and are connected to the nuts.

[0037] Specifically, the brush holder fixing plate is made of resin board, which has good insulation and strength. The brush holder fixing plate has grooves and positioning holes at both ends for easy fixing with the fixing plate using the first positioning bolt. The side panel is also made of resin board. The back of the brush holder fixing plate and the back of the side panel have brush holder grooves and side panel grooves respectively, and are positioned through positioning holes. Combined with the mounting holes in the square groove, the clearance holes in the side panel, and the slots in the fixing plate, insulation can be directly achieved, reducing the frequency of short circuits.

[0038] In practice, mounting bolt 6 is either a square-head bolt or a hexagonal bolt. Preferably, the mounting bolt is a square-head bolt, as the size of the square head fits perfectly into the groove of the brush holder, securing the bolt and allowing for a tighter tightening of the carbon brush wire connection, preventing loosening. This effectively prevents the bolt from loosening due to vibration during equipment operation. Furthermore, the square head provides greater torque when connecting the carbon brush wire, further improving connection reliability and effectively preventing poor contact or electrical faults caused by loose bolts. This ensures a stable connection between the carbon brush and the slip ring, as well as reliable transmission of electrical energy and signals.

[0039] During implementation, the width of the slot is greater than the diameter of the mounting bolt, which plays an important role in insulation protection.

Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
