Description

Technical Field

[0001] The invention belongs to the technical field of cable equipment, and in particular relates to a brush holder for cable equipment production and a use method thereof. Background Art

[0002] Brushes are a crucial component of electric motors, conducting current between rotating and stationary parts. Because they're often made of graphite, they're also called carbon brushes. They're typically mounted inside a brush holder in a motor. The brush holder is the device that holds the brushes, ensuring they're positioned accurately on the commutator. This ensures full, close contact between the brushes and the commutator, maintaining a constant contact voltage drop and preventing brush bounce that could cause sparks and commutation failures. Brush holders are often used to assist in the production of cable equipment.

[0003] During the production and processing process, it is often necessary to fix the brush holder, such as the brush holder for manufacturing wire and cable equipment disclosed in application No. 201811148272.0 and its use method, which cooperates with a workbench, a brush holder body, a support foot, a horizontal shaft, a first plate, a second plate, a rotating groove, a screw rod, a sprocket, a chain, a vertical hole, a movable plate and a threaded groove. Hold the anti-slip sleeve on the horizontal shaft with both hands and rotate the horizontal shaft. Since the sprocket on the horizontal shaft and the outer side of the sprocket on the screw rod are engaged with the same chain, the screw rod is driven to rotate, and the screw rod is threadedly connected to the threaded groove, driving the movable plate to move, and the movable plate drives the rectangular plate to move to achieve the fixation of the brush holder. Although it can effectively fix the brush holder, in actual use, it is necessary to manually twist the horizontal shaft to finally drive the rotation of the screw rod to achieve the fixation of the brush holder. When fixing, a large force needs to be manually applied to complete the fixing process. At the same time, when disassembling, a large force needs to be applied in the reverse direction to achieve disassembly, resulting in low fixing efficiency.

[0004] At the same time, this application can clamp and fix an irregularly shaped brush holder by adjusting the position of the clamping ball. Although this application uses multiple clamping balls, the outer side of the brush holder is contacted and fixed through the different relative positions of the multiple clamping balls, but the clamping ball is connected to the sliding plate, and the sliding plate is connected to the spring. The spring fixation is extremely unstable. When the brush holder vibrates, the vibration will be transmitted to the spring, causing the spring to stretch or compress, thereby causing the brush holder to loosen. Summary of the Invention

[0005] The object of the present invention is to provide a brush holder for cable equipment production and a method of using the same, so as to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned objectives, the present invention provides the following technical solutions: a brush holder for cable equipment production, comprising a frame, a guide rail is fixedly installed on the top of the frame, and clamps are provided on the left and right sides of the top of the guide rail, a brush holder body is provided above the guide rail between the two clamps, an oil storage pipe is provided on the inner side surface of the frame, and oil delivery components are fixedly installed on the left and right sides of the bottom end of the frame, a bottom plate located below the oil storage pipe is fixedly connected between the two oil delivery components, the outer side surface of the oil storage pipe is fixedly sleeved with a fixing frame, the bottom end of the fixing frame is fixedly connected to the top end of the bottom plate, the inside of the oil storage pipe is movably sleeved with a first piston plate, the left and right sides of the inside of the guide rail are symmetrically and movably clamped with guide blocks, the top of the guide block is connected to the bottom end of the clamp, and the bottom end of the oil storage pipe is fixedly connected to a three-way valve.

[0007] Before using the device, you must first determine the shape of the brush holder body to be clamped, and connect it with the oil delivery component through the external three-way valve, ensure that the hydraulic oil inside the oil delivery component is in a flowable state, and connect the external compressed gas tank with the input port of the external three-way valve, and place the device vertically and stably to complete the preparation.

[0008] As a further technical solution of the present invention, the bottom ends of the two guide blocks are fixedly connected to a first fixing seat, and the end of the first fixing seat away from the guide block is movably connected to a connecting rod through a rotating shaft.

[0009] As a further technical solution of the present invention, a movable rod located inside the oil storage pipe is fixedly installed in the middle of the top of the first piston plate, and the top of the movable rod passes through the top of the oil storage pipe and is fixedly installed with a movable plate.

[0010] As a further technical solution of the present invention, second fixing seats are fixedly installed on both the left and right sides of the top of the movable plate, and the interior of the second fixing seat is rotatably connected to the other end of the connecting rod through a rotating shaft.

[0011] A channel for hydraulic oil to flow in is provided between the bottom end of the first piston plate and the bottom end of the inner cavity of the oil storage tube. When the movable plate is displaced downward, the two connecting rods can be deflected inward, which can drive the two first fixed seats to be relatively close to each other, that is, the guide blocks slide relative to the guide rails and approach each other. When the movable plate is displaced upward, the two connecting rods can be deflected outward, which can drive the two first fixed seats to be relatively away from each other, that is, the two guide blocks are relatively away from each other at the same time.

[0012] As a further technical solution of the present invention, the oil delivery component includes an oil delivery tank, which stores hydraulic oil inside. The oil delivery tank is movably sleeved with a second piston plate, and hydraulic oil is provided between one end of the second piston plate close to the bottom plate and the inner cavity of the oil delivery tank.

[0013] As a further technical solution of the present invention, one end of the second piston plate away from the base plate is fixedly connected to a piston rod located inside the oil tank, the other end of the piston rod away from the second piston plate passes through one end of the oil tank and is fixedly connected to an indicator plate, and a return spring is movably sleeved on the outer side of the piston rod, and the left and right ends of the return spring are respectively fixedly connected to one end of the second piston plate and one end of the oil tank.

[0014] As a further technical solution of the present invention, the rear end of the oil tank away from the bottom plate is fixedly connected to an intake valve, and the front end of the oil tank away from the bottom plate is fixedly connected to an exhaust valve. Both the intake valve and the exhaust valve are installed with a one-way valve inside, and the directions of the valves are inward conduction and outward blocking and outward conduction and inward blocking, respectively.

[0015] When the brush holder body of a regular shape is clamped and fixed, the external compressed air tank can be opened to introduce compressed air into the interior of the two intake valves. As the compressed air continues to enter, the second piston plate is immediately displaced toward the bottom plate by pressure. At this time, the return spring is compressed and the exhaust pipe valve is closed. The hydraulic oil inside the oil tank immediately passes through the two ends of the three-way valve and enters the interior of the oil storage pipe through the output end of the three-way valve, driving the first piston plate to rise. At this time, the movable rod and the movable plate rise accordingly, and the two connecting rods deflect outward and drive the two guide blocks to move relatively away from each other until the distance between the two guide blocks is sufficient to allow the brush holder body to be placed. The valve at the top of the three-way valve is closed to complete the fixation of the brush holder body of a regular shape.

[0016] By utilizing compressed air and continuously entering compressed air to realize the transportation of hydraulic oil in a closed state, the most suitable hydraulic oil flow rate is found and the flow rate of the hydraulic oil is controlled to remain unchanged, so as to realize the fixation of the brush holder body in a regular state. During the entire fixing process, the clamping force will not change due to the constant hydraulic oil. At the same time, the whole process is completed quickly and can be completed without manually applying a large force. When disassembling, it is only necessary to open the valve and close the air source. The clamping is stable and the clamping efficiency is high, which is suitable for batch processing.

[0017] As a further technical solution of the present invention, the end of the exhaust valve away from the oil tank is fixedly connected to the air intake box, the side of the air intake box is fixedly connected to the exhaust pipe, an electromagnetic valve is installed inside the exhaust pipe, the end of the air intake box away from the exhaust valve is fixedly connected to a bellows, and the end of the bellows away from the air intake box is fixedly connected to a connecting pipe.

[0018] As a further technical solution of the present invention, anti-slip grooves are provided at equal distances on the relatively close ends of the two splints, an air storage cavity is provided in the middle of the splint, the air storage cavity is connected to the connecting pipe, and air bags are fixedly installed on the relatively close ends of the two splints, the air bags are connected to the interior of the splint, and the air bags are made of rubber.

[0019] When it is necessary to fix the irregular-shaped brush holder body, the valve of the exhaust valve can be opened to introduce compressed air into the interior of the air intake box, and then the compressed air is transported into the interior of the air storage chamber through the bellows and the connecting pipe. As the compressed air increases, the air bag is filled with air and expands, increasing its volume, filling the gap between the clamping plate and the brush holder body, increasing the contact area and completing the fixation. When disassembling, the valve of the exhaust pipe can be opened to release the compressed air, reducing the volume of the air bag so that it no longer fills the gap between the brush holder body and the clamping plate, completing the disassembly.

[0020] By further utilizing the compressed air and taking advantage of its fluidity, the volume of the airbag is increased and expanded. Relying on the action of the fluid, the outer surface of the airbag can be compressed into various shapes and always keep in contact with the brush holder body, filling the gaps, effectively increasing the contact area, and thus improving the clamping stability, so that any irregularly shaped brush holder body can still be effectively fixed, and the clamping state can be maintained by only keeping the air volume inside the airbag unchanged, avoiding the problem of loosening of the equipment caused by the spring fixing method of the traditional device, and having higher clamping stability.

[0021] A method for using a brush holder for cable equipment production, comprising the following steps:

[0022] S1: When the brush holder body needs to be clamped and fixed, first, the external three-way valve can be connected to the air inlet valve on one side of the two oil delivery components, and compressed air can be connected to one end of the external three-way valve to complete the preparation work;

[0023] S2: When fixing, the external compressed air source can be turned on to inject compressed air into the interior of the intake valve. At this time, the compressed air can exert forward pressure on the second piston plate. At this time, the return spring is compressed, and the second piston plate moves toward the bottom plate. The hydraulic oil in the oil tank then enters the oil storage pipe through the three-way valve, and the first piston plate drives the movable rod and the movable plate to rise:

[0024] S3: As the hydraulic oil is continuously injected, the movable plate rises and the connecting rod deflects outward. At this time, the angle between the two connecting rods increases, and the first fixing seat and the guide block move away from each other, driving the clamping plates to move away from each other. When the two clamping plates move away from each other to a certain distance, that is, when the brush holder body can be clamped and fixed by the two clamping plates, the valve at the top of the three-way valve is closed to complete the fixation of the brush holder body.

[0025] S4: When the shape of the guide block is irregular, the exhaust valve can be opened continuously. At this time, compressed air can be injected into the interior of the bellows through the air intake box and enter the air storage cavity through the connecting pipe, filling the airbag at the same time. The airbag expands and increases its volume, filling the gap between the brush holder body and the splint, thereby completing the fixation of the irregular-shaped brush holder body.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. The present invention utilizes compressed air and the continuously entering compressed air to realize the transportation of hydraulic oil in a closed state, thereby finding the most suitable hydraulic oil flow rate and controlling the flow rate of the hydraulic oil to remain unchanged, thereby achieving the fixation of the brush holder body in a regular state. During the entire fixing process, the clamping force will not change due to the constant hydraulic oil. At the same time, the whole process is completed quickly and can be completed without manually applying a large force. When disassembling, it is only necessary to open the valve and close the air source. The clamping is stable and the clamping efficiency is high, which is suitable for batch processing.

[0028] 2. The present invention further utilizes the fluidity of compressed air to increase the volume of the airbag and expand it. Relying on the action of the fluid, the outer surface of the airbag can be compressed into various shapes and always keep in contact with the brush holder body, and fill the gap, effectively increasing the contact area, thereby improving the clamping stability, so that any irregular-shaped brush holder body can still be effectively fixed, and the clamping state can be maintained by only keeping the air volume inside the airbag unchanged, avoiding the problem of loosening of the equipment caused by the spring fixing method of the traditional device, and the clamping stability is high.

[0041] like Figure 3 and Figure 5 as well as Figure 6 As shown, the bottom ends of the two guide blocks 4 are fixedly connected to the first fixed seat 5, and the end of the first fixed seat 5 away from the guide block 4 is movably connected to the connecting rod 7 through a rotating shaft. The middle part of the top of the first piston plate 11 is fixedly installed with a movable rod 9 located inside the oil storage pipe 10. The top of the movable rod 9 passes through the top of the oil storage pipe 10 and is fixedly installed with a movable plate 8. The left and right sides of the top of the movable plate 8 are fixedly installed with a second fixed seat 6, and the interior of the second fixed seat 6 is rotatably connected to the other end of the connecting rod 7 through a rotating shaft.

[0042] A channel for hydraulic oil to flow into is provided between the bottom end of the first piston plate 11 and the bottom end of the inner cavity of the oil storage pipe 10. When the movable plate 8 is displaced downward, the two connecting rods 7 can be deflected inward, which can drive the two first fixed seats 5 to be relatively close, that is, the guide blocks 4 slide relative to the guide rails 2 and approach each other. When the movable plate 8 is displaced upward, the two connecting rods 7 can be deflected outward, which can drive the two first fixed seats 5 to be relatively away from each other, that is, the two guide blocks 4 are relatively away from each other at the same time.

[0043] like Figure 3 and Figure 5 as well as Figure 6 and Figure 7 As shown, the oil delivery assembly 15 includes an oil delivery tank 151, the interior of the oil delivery tank 151 stores hydraulic oil, the interior of the oil delivery tank 151 is movably sleeved with a second piston plate 152, and hydraulic oil is provided between the end of the second piston plate 152 close to the bottom plate 13 and the inner cavity of the oil delivery tank 151, and the end of the second piston plate 152 away from the bottom plate 13 is fixedly connected to a piston rod 153 located inside the oil delivery tank 151, and the end of the piston rod 153 away from the second piston plate 152 passes through one end of the oil delivery tank 151 and is fixedly connected to an indicator plate 154, which is movably sleeved.

The rear end of the oil tank 151 away from the base plate 13 is fixedly connected to an intake valve 156, and the front end of the oil tank 151 away from the base plate 13 is fixedly connected to an exhaust valve 157. Both the intake valve 156 and the exhaust valve 157 are installed with a one-way valve inside, and the directions of the valves are inward conduction and outward cut-off and outward conduction and inward cut-off, respectively.

[0044] First embodiment:

[0045] When the brush holder body 3 of a regular shape is clamped and fixed, the external compressed air tank can be opened to introduce compressed air into the interior of the two air inlet valves 156. As the compressed air continues to enter, the second piston plate 152 is immediately displaced toward the bottom plate 13 by pressure. At this time, the return spring 155 is compressed, and the exhaust pipe 17 valve is closed. The hydraulic oil inside the oil tank 151 immediately passes through the two ends of the three-way valve 14 and enters the interior of the oil storage pipe 10 through the output end of the three-way valve 14, and drives the first piston plate 11 to rise. At this time, the movable rod 9 and the movable plate 8 rise accordingly, and the two connecting rods 7 deflect outward and drive the two guide blocks 4 to move relatively away from each other until the distance between the two guide blocks 4 is sufficient to allow the brush holder body 3 to be placed in. The valve at the top of the three-way valve 14 is closed to complete the fixation of the brush holder body 3 of the regular shape.

[0046] By utilizing compressed air, the continuously entering compressed air is used to transport the hydraulic oil in a closed state, thereby finding the most suitable hydraulic oil flow rate and controlling the flow rate of the hydraulic oil to remain unchanged, so as to achieve the fixation of the brush holder body 3 in the regular state. During the entire fixing process, the clamping force will not change due to the constant hydraulic oil. At the same time, the whole process is completed quickly and can be completed without manually applying a large force. When disassembling, it is only necessary to open the valve and close the air source. The clamping is stable and the clamping efficiency is high, which is suitable for batch processing.

[0047] like Figure 3 and Figure 4 as well as Figure 7 and Figure 8 As shown, the end of the exhaust valve 157 away from the oil tank 151 is fixedly connected to the air intake box 16, the side of the air intake box 16 is fixedly connected to the exhaust pipe 17, the exhaust pipe 17 is installed inside the solenoid valve, the end of the air intake box 16 away from the exhaust valve 157 is fixedly connected to the bellows 18, the end of the bellows 18 away from the air intake box 16 is fixedly connected to the connecting pipe 19, the relatively close ends of the two splints 20 are evenly spaced with anti-skid grooves 21, the middle part of the splint 20 is provided with an air storage cavity 22, the air storage cavity 22 is connected to the connecting pipe 19, the relatively close ends of the two splints 20 are fixedly installed with air bags 23, the air bags 23 are connected to the inside of the splint 20, and the air bags 23 are made of rubber.

[0048] Second embodiment:

[0049] When it is necessary to fix the irregularly shaped brush holder body 3, the exhaust valve 157 can be opened to introduce compressed air into the air inlet box 16, and then the compressed air is transported into the air storage chamber 22 through the bellows 18 and the connecting pipe 19. As the compressed air increases, the airbag 23 is filled with air and expands in volume, filling the gap between the clamping plate 20 and the brush holder body 3, increasing the contact area and completing the fixation. When disassembling, the compressed air can be released by opening the valve of the exhaust pipe 17, reducing the volume of the airbag 23 so that it no longer fills the gap between the brush holder body 3 and the clamping plate 20, completing the disassembly.

[0050] By further utilizing the compressed air and taking advantage of its fluidity, the volume of the airbag 23 is increased and expanded, and relying on the action of the fluid, the outer surface of the airbag 23 can be compressed into various shapes and always keep in contact with the brush holder body 3, and fill the gap, thereby effectively increasing the contact area and improving the clamping stability, so that any irregularly shaped brush holder body 3 can still be effectively fixed, and the clamping state can be maintained by only keeping the air volume inside the airbag 23 unchanged, avoiding the problem of loosening of the equipment caused by the spring fixing method of the traditional device, and the clamping stability is high.

[0051] A method for using a brush holder for cable equipment production, comprising the following steps:

[0052] S1: When the brush holder body 3 needs to be clamped and fixed, first, the external three-way valve can be fixedly connected to the air inlet valve 156 on one side of the two oil delivery components 15, and compressed air is connected to one end of the external three-way valve to complete the preparation work;

[0053] S2: When fixing, the external compressed air source can be turned on to inject compressed air into the interior of the air inlet valve 156. At this time, the compressed air can apply forward pressure to the second piston plate 152. At this time, the return spring 155 is compressed, and the second piston plate 152 moves toward the bottom plate 13. The hydraulic oil in the oil tank 151 then enters the interior of the oil storage pipe 10 through the three-way valve 14, and the first piston plate 11 then drives the movable rod 9 and the movable plate 8 to rise:

[0054] S3: As the hydraulic oil is continuously injected, the movable plate 8 rises and the connecting rod 7 deflects outward. At this time, the angle between the two connecting rods 7 increases, and the first fixing seat 5 and the guide block 4 move away from each other, driving the clamping plates 20 to move away from each other. When the two clamping plates 20 move away from each other to a certain distance, that is, when the brush holder body 3 can be clamped and fixed by the two clamping plates 20, the valve at the top of the three-way valve 14 is closed to complete the fixation of the brush holder body 3.

[0055] S4: When the shape of the guide block 4 is irregular, the valve of the exhaust valve 157 can continue to be opened. At this time, the compressed air can be injected into the interior of the bellows 18 through the air inlet box 16 and enter the air storage chamber 22 through the connecting pipe 19, while filling the airbag 23, causing the airbag 23 to expand and increase its volume, filling the gap between the brush holder body 3 and the splint 20, and completing the fixation of the irregular-shaped brush holder body 3.

[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

The brush holder for cable equipment production according to claim 5, characterized in that: Anti-slip grooves (21) are evenly spaced at the ends of the two splints (20) that are relatively close to each other. An air storage cavity (22) is opened in the middle of the splint (20). The air storage cavity (22) is connected to the connecting pipe (19). An air bag (23) is fixedly installed at the ends of the two splints (20) that are relatively close to each other. The air bag (23) is connected to the inside of the splint (20). The air bag (23) is made of rubber.

7. A method for using a brush holder for cable equipment production according to any one of claims 1 to 6, characterized in that: This includes the following methods: S1: When the brush holder body (3) needs to be clamped and fixed, first, an external three-way valve can be connected to the air inlet valve (156) on one side of the two oil delivery components (15) and compressed air is connected to one end of the external three-way valve to complete the preparation work; S2: When fixing, the external compressed air source can be opened to inject compressed air into the interior of the air inlet valve (156). At this time, the compressed air can apply forward pressure to the second piston plate (152). At this time, the return spring (155) is compressed, and the second piston plate (152) moves toward the bottom plate (13). The hydraulic oil in the oil tank (151) then enters the interior of the oil storage pipe (10) through the three-way valve (14). The first piston plate (11) then drives the movable rod (9) and the movable plate (8) to rise: S3: As the hydraulic oil is continuously injected, the movable plate (8) rises and the connecting rod (7) deflects outward. At this time, the angle between the two connecting rods (7) increases, and the first fixing seat (5) and the guide block (4) move away from each other and drive the clamping plate (20) to move away from each other. When the two clamping plates (20) move away from each other to a certain distance, that is, when the brush holder body (3) can be clamped and fixed by the two clamping plates (20), the valve at the top of the three-way valve (14) is closed to complete the fixation of the brush holder body (3); S4: When the shape of the guide block (4) is irregular, the exhaust valve (157) can be opened continuously. At this time, the compressed air can be injected into the interior of the bellows (18) through the air inlet box (16) and enter the air storage chamber (22) through the connecting pipe (19), and at the same time fill the airbag (23), so that the airbag (23) expands and increases in volume, filling the gap between the brush holder body (3) and the clamping plate (20), thereby completing the fixation of the irregular-shaped brush holder body (3).
