Description

Technical Field

[0001] The present invention relates to the technical field of linear motors, and particularly to a high-precision intelligent air-cooled detection motor for fatigue detection of metal parts. Background Art

[0002] Metal parts used in high-intensity working environments need to be subjected to fatigue strength detection during production. Usually, a linear motor is used to repeatedly bend or swing them to detect the anti-fatigue strength of the parts, so as to judge the service life of the parts.

[0003] However, the existing linear motors are inconvenient to adjust the operating range of the mover during operation, resulting in difficulty in flexibly adjusting the movement amplitude during the part detection process, and it is difficult to detect the service life of parts in a large-amplitude vibration environment. At the same time, since the mover assembly reciprocally slides on the stator assembly, a large amount of heat will be generated due to the friction between the two. At the same time, the Ohmic heat generated by the current passing through the windings inside the motor, as well as the heat caused by mechanical friction and internal resistance, if not dissipated in time, will cause the internal temperature of the motor to rise sharply, thereby affecting the continuous working time and service life of the motor.

Detailed implementation manners

[0028] The technical solution provided by the present invention will be further described below in conjunction with the accompanying drawings and according to the specific implementation manners.

[0029] As Figures 1 to 10 shown, a high-precision intelligent air-cooled detection motor for fatigue detection of metal parts includes a stator bracket 2. The stator bracket 2 includes a cooling bracket 203. Cooling fans 3 are fixedly installed on both sides of the cooling bracket 203. A mover bracket 1 is horizontally slidably installed inside the cooling bracket 203. A coil bracket 208 is fixedly installed inside the cooling bracket 203. The coil bracket 208 is provided with a plurality of exhaust holes. A plurality of coil partitions 209 are fixedly installed on the coil bracket 208. A magnetic flux coil 211 is wound between two coil partitions 209. The exhaust holes on the coil bracket 208 are located in the gaps between the two sides of the magnetic flux coil 211 and the coil partitions 209. A coil dust cover 210 is horizontally rotatably installed between the coil partitions 209. The coil dust cover 210 is provided with a plurality of obliquely arranged air inlets. An inclined wind deflector is arranged inside the air inlet to prevent dust from falling on the magnetic flux coil 211 from the air inlet during the placement of the device, and to make the air blow towards the magnetic flux coil 211 at an inclined angle during operation, increasing the contact area between the surface of the magnetic flux coil 211 and the air while preventing dust from entering the interior, and improving the heat dissipation effect of the magnetic flux coil 211.

[0030] As Figures 1 to 10As shown, the mover bracket 1 includes a detection connecting frame 101, which is used to load metal parts to be detected. A mover core 103 is fixedly installed on the detection connecting frame 101, and the mover core 103 is installed in a coil bracket 208 for transverse sliding. There is a certain distance between the inner wall of the coil bracket 208 and the outer wall of the mover core 103. The air in the coil dust cover 210 enters the inside of the coil bracket 208 from the exhaust port on the coil bracket 208, and is discharged through the air between the coil bracket 208 and the mover core 103. At the same time, the heat generated by the inner circle of the flux coil 211 is taken away from the inner wall of the coil bracket 208. A permanent magnet group 106 is installed in the detection connecting frame 101 for transverse sliding. The mover core 103 is fixedly installed at both ends. An anti-collision plate 104 and an adjusting screw 107 are installed horizontally and rotatably between the anti-collision plates 104. The adjusting screw 107 cooperates with the lead screw of the permanent magnet group 106. An adjusting motor 109 is fixedly installed in the detection connecting frame 101. The adjusting motor 109 is fixedly connected to the adjusting screw 107. By starting the adjusting motor 109, the adjusting screw 107 is driven to rotate. The rotation of the adjusting screw 107 drives the permanent magnet group 106 to slide in the movable core 103, and the extension distance of the movable core 103 on the heat dissipation bracket 203 can be adjusted, so as to adjust the range of movement of the movable core 103 under a fixed stroke, so that the movable core 103 can be more flexibly adjusted to the detection range during operation, so as to detect the fatigue resistance of metal parts under different bending degrees.

[0031] like Figures 1 to 10 As shown, a wind resistance push plate 108 is fixedly installed on the outer wall of the movable core 103, and the wind resistance push plate 108 is located between the movable core 103 and the coil bracket 208. The air flowing in the coil bracket 208 will generate resistance when passing through the wind resistance push plate 108, thereby slowing down the sliding speed of the movable core 103 in the coil bracket 208. The front and rear ends of the heat dissipation bracket 203 are fixedly installed with magnetic circle heat dissipation ports 204. The movable core 103 slides with the magnetic circle heat dissipation ports 204 and does not contact the movable core 103. The air in the coil bracket 208 is discharged through the magnetic circle heat dissipation ports 204, and the magnetic circle heat dissipation A heat dissipation adjustment cover 216 is installed on the outer side of the opening 204 for horizontal rotation. The heat dissipation adjustment cover 216 is used to control the efficiency of air exhaustion from the magnetic circle heat dissipation opening 204. The efficiency of air exhaustion from the magnetic circle heat dissipation opening 204 is adjusted by rotating the heat dissipation adjustment cover 216, and the flow direction of air in the coil bracket 208 is adjusted. The air flowing through the coil bracket 208 pushes the wind resistance push plate 108 to move in the direction of air flow, thereby increasing the power of the movable core 103 when sliding in the direction of air flow, thereby avoiding insufficient thrust when the movable core 103 pushes the detection part to move, resulting in failure to reach the specified stroke, thereby affecting the detection efficiency.

[0032] like Figures 1 to 10As shown, one end of the heat dissipation bracket 203 is fixedly installed with a monitoring cylinder 214. The monitoring cylinder 214 is fixedly installed on the inner wall of the magnetic ring heat dissipation port 204. A plurality of detection rods 215 are slidably installed in the monitoring cylinder 214 along the radial direction. A detection wheel is fixedly installed on the detection rod 215. The detection wheel on the detection rod 215 is in contact and cooperation with the outer wall of the mover core 103, and is used to monitor the sliding stroke of the mover core 103.

[0033] As Figures 1 to 10 As shown, a heat dissipation top cover 201 is fixedly installed on the top of the heat dissipation bracket 203. Chute grooves are provided on both the bottom of the heat dissipation bracket 203 and the top of the heat dissipation top cover 201. An upper suspension rod 102 is fixedly installed on the top of the detection connection frame 101. The upper suspension rod 102 is slidably fitted with the chute groove on the top of the heat dissipation top cover 201. A lower suspension rod 105 is fixedly installed on the bottom of the detection connection frame 101. The lower suspension rod 105 is slidably fitted with the chute groove on the bottom of the heat dissipation bracket 203. Permanent magnets are fixedly installed on the bottom and both sides of the chute grooves at the bottom of the heat dissipation bracket 203 and the top of the heat dissipation top cover 201. Permanent magnets are fixedly installed on the bottom and both sides of the upper suspension rod 102 and the lower suspension rod 105. The permanent magnet on the upper suspension rod 102 repels the permanent magnet in the chute groove of the heat dissipation top cover 201, and the permanent magnet on the lower suspension rod 105 repels the permanent magnet in the chute groove of the heat dissipation bracket 203, so as to control the overall suspension of the mover core 103 in the coil bracket 208, so that the mover core 103 does not rub against the coil bracket 208 and the magnetic ring heat dissipation port 204, further reducing the heat generated when the mover core 103 works and improving the operation time of the device.

[0034] As Figures 1 to 10As shown in the figure, the outer ring of the coil dust cover 210 is provided with gear teeth. A pair of adjustable heat dissipation plates 207 are longitudinally and slidably installed in the heat dissipation bracket 203. A compression spring is fixedly installed between the two adjustable heat dissipation plates 207. A rack is fixedly installed on the adjustable heat dissipation plate 207. The rack on the adjustable heat dissipation plate 207 meshes with the gear teeth on the outer ring of the coil dust cover 210. Two pairs of transmission racks are fixedly installed at the front and rear ends of the adjustable heat dissipation plate 207. Two pairs of transmission gears 213 are horizontally and rotatably installed in the heat dissipation bracket 203. The transmission racks on the adjustable heat dissipation plate 207 mesh with the transmission gears 213, which is used to control the synchronous relative sliding of the two adjustable heat dissipation plates 207. An adjustable rotating rod 212 is horizontally and rotatably installed on the top of the heat dissipation top cover 201. Cams are fixedly installed at both ends of the adjustable rotating rod 212. The cams at both ends of the adjustable rotating rod 212 are in contact and cooperation with the top of the adjustable heat dissipation plate 207. A gear is fixedly installed on the adjustable rotating rod 212. A rack is fixedly installed at the bottom of the upper suspension rod 102. The rack at the bottom of the upper suspension rod 102 meshes with the gear on the adjustable rotating rod 212. When the mover core 103 slides in the coil bracket 208, it drives the upper suspension rod 102 to slide in the chute on the top of the heat dissipation top cover 201, and drives the adjustable rotating rod 212 to rotate on the heat dissipation top cover 201 through the rack at the bottom of the upper suspension rod 102. The adjustable heat dissipation plates 207 at the top of the heat dissipation bracket 203 are driven by the cams on both sides of the adjustable rotating rod 212 to slide in the heat dissipation bracket 203. At the same time, the adjustable heat dissipation plate 207 at the bottom is driven to slide synchronously through the transmission gear 213. The coil dust cover 210 is driven to rotate on the coil partition 209 through the rack on the adjustable heat dissipation plate 207, so that the airflow blowing to the surface of the flux coil 211 rotates, avoiding the generation of heat dissipation dead angles and improving the heat dissipation efficiency of the flux coil 211.

[0035] As Figures 1 to 10 shown, a deceleration bracket 205 is horizontally slidably installed at the top of the heat dissipation top cover 201 and the bottom of the heat dissipation bracket 203. An electromagnet is fixedly installed inside the deceleration bracket 205. Deceleration plates 110 are fixedly installed at the front ends of the upper suspension rod 102 and the lower suspension rod 105. Permanent magnets are fixedly installed on both the front and rear sides of the deceleration plate 110. The permanent magnets on the deceleration plate 110 repel the electromagnet inside the deceleration bracket 205. When the equipment is running, the electromagnet inside the deceleration bracket 205 is started, and the speed of the mover core 103 when sliding to the extreme stroke is slowed down through this simple repulsion, improving the smoothness of the sliding of the mover core 103.

[0036] As Figures 1 to 10As shown, a pair of driving screws 206 are installed on the top of the heat dissipation cover 201 and the bottom of the heat dissipation bracket 203 for horizontal rotation. The driving screws 206 cooperate with the lead screw of the reduction bracket 205. A pulley is fixedly installed on the driving screw 206. The driving screws 206 are connected by belts. A driving motor 202 is fixedly installed on the heat dissipation bracket 203. The driving motor 202 is fixedly connected to the driving screw 206. The driving screw 206 is driven to rotate by starting the driving motor 202. The rotation of the driving screw 206 drives the reduction bracket 205 to slide at the bottom of the heat dissipation bracket 203 and the top of the heat dissipation cover 201, so that the deceleration range of the reduction bracket 205 is adjusted according to the sliding range of the movable core 103.
