[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This utility model provides a device for cleaning burrs on motor core laminations. When the cylinder is running, its output end drives the slider to move downward along the guide rail. The inclined block on the right side of the slider moves downward synchronously. The inclined surface of the inclined block pushes the roller, causing the movable rod to move to the left against the elastic force of the spring. The push plate at the front end of the movable rod presses the switch, thereby controlling the motor to stop running. At this time, the support base stops rotating, which moves one of the positioning mechanisms directly below the deburring rod, achieving precise positioning of the laminations. Multiple motor cores can be clamped at one time, resulting in high processing efficiency.

[0019] 2. This utility model provides a device for cleaning burrs on motor iron core laminations. After the fan in the adsorption assembly is started, negative pressure is generated through the telescopic hose and adsorption ring, which sucks the metal dust generated during the deburring process into the installation box. After the dust is filtered by the filter screen, the larger dust particles fall into the collection box, while the air is discharged by the fan. This effectively reduces dust pollution in the working environment, improves operating conditions, and protects the health of operators. At the same time, the fixing assembly can quickly disassemble the installation handle and filter screen through the plug-in cooperation of the plug rod and the locking structure of the limit rod and the locking block, which is convenient for cleaning and maintenance and ensures the continuity of dust reduction effect.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figure 1-7 As shown, a device for cleaning burrs on motor core laminations includes a workbench 1, a motor 2 fixedly connected to the top of the workbench 1, a support base 3 fixedly connected to the output end of the motor 2, multiple positioning mechanisms 4 arranged in a ring on the support base 3, a fixed frame 5 fixedly connected to the rear side of the top of the workbench 1, a cylinder 6 fixedly connected to the top of the fixed frame 5, a motor 7 fixedly connected to the output end of the cylinder 6, a slider 8 fixedly connected to the rear side of the motor 7, two guide rails 9 slidably connected inside the slider 8, the rear side of the guide rails 9 fixedly connected to the front side of the fixed frame 5, a fixed disk 10 fixedly connected to the output end of the motor 7, multiple deburring rods 11 fixedly connected to the bottom of the fixed disk 10, a control mechanism 12 provided on the right side of the slider 8, and a dust suppression mechanism 13 provided on the rear side of the fixed frame 5.

[0030] The control mechanism 12 includes a wedge 121, a first fixed plate 122, and a second fixed plate 123. The left side of the wedge 121 is fixedly connected to the right side of the slider 8. The rear sides of the first fixed plate 122 and the second fixed plate 123 are both fixedly connected to the front side of the fixed frame 5. A movable rod 124 is slidably connected inside the first fixed plate 122. A push plate 125 is fixedly connected to one end of the movable rod 124, and a fixed seat 126 is fixedly connected to the other end of the movable rod 124. A roller 127 is rotatably connected inside the fixed seat 126, and a spring 128 is sleeved on the outside of the roller 127. A switch 129 is fixedly connected to the left side of the second fixed plate 123.

[0031] It should be noted that when deburring is required, cylinder 6 is activated, and its output pushes motor 7 and slider 8 to move downwards along guide rail 9. The inclined block 121 on the right side of slider 8 moves downwards accordingly. The inclined surface of inclined block 121 contacts roller 127 and applies a pushing force, causing roller 127 to move movable rod 124 to the left, compressing spring 128. The push plate 125 at the front end of movable rod 124 moves to one side and presses against switch 129. Switch 129 sends a signal to stop motor 2. At this time, support base 3 stops rotating, ensuring that one of the positioning mechanisms 4 is accurately positioned below deburring rod 11, providing precise positioning for subsequent cleaning work.

[0032] The dust collection mechanism 13 includes an adsorption component 14, which is mounted on the front side of the mounting frame 5 and has mounting components 15 on both the left and right sides of the adsorption component 14.

[0033] It should be noted that during the processing, the adsorption component 14 adsorbs and filters metal dust, and the fixing component 15 facilitates the disassembly and cleaning of the filter screen 144.

[0034] like Figure 4 As shown, one end of spring 128 is fixedly connected to the side of fixed plate 122 away from fixed plate 123, and the other end of spring 128 is fixedly connected to the outside of fixed base 126.

[0035] It should be noted that spring 128 provides elastic force for the fixed base 126 to return to its original position.

[0036] like Figure 3 and Figure 4 As shown, the push plate 125 abuts against the switch 129, and the bottom of the support base 3 is slidably connected inside the worktable 1.

[0037] It should be noted that the push plate 125 and the switch 129 abut against each other, which can control the start of motor 2. The support base 3 is rotatably connected to the worktable 1, which enables the support base 3 to rotate stably.

[0038] like Figure 6 As shown, the adsorption assembly 14 includes a mounting box 141. The front side of the mounting box 141 is fixedly connected to the rear side of the mounting frame 5. A fan 142 is installed on the rear side of the mounting box 141. An installation handle 143 is slidably connected inside the mounting box 141. A filter screen 144 is fixedly connected to the bottom of the installation handle 143. A collection box 145 is slidably connected inside the mounting box 141 and below the filter screen 144. A telescopic hose 146 is fixedly connected to the right side of the outside of the mounting box 141. The end of the telescopic hose 146 away from the mounting box 141 passes through the mounting frame 5 and the slider 8 and is fixedly connected to an adsorption ring 147.

[0039] It should be noted that during the deburring process, the fan 142 is started, and a negative pressure is formed in the cleaning area through the telescopic hose 146 and the adsorption ring 147. The metal dust generated by the rotating deburring rod 11 cleaning the punch is sucked in by the adsorption ring 147, enters the installation box 141 through the telescopic hose 146, and the dust is filtered and intercepted by the filter screen 144 in the installation box 141 and falls into the collection box 145. The purified air is discharged through the fan 142, realizing efficient collection and purification of dust.

[0040] like Figure 7 As shown, the fixing component 15 includes a housing 151. The inner side of the housing 151 is fixedly connected to the outer side of the mounting box 141. A sliding groove 152 is provided on the top of the housing 151. An insert rod 153 is slidably connected inside the housing 151. A baffle 154 is fixedly connected to one end of the insert rod 153. An L-shaped block 155 is fixedly connected to the top of the baffle 154. A limiting rod 156 is sleeved inside the L-shaped block 155. A spring 157 is provided inside the housing 151. A locking block 158 is fixedly connected to the outer side of the housing 151.

[0041] It should be noted that when cleaning the filter screen 144 and the collection box 145, pull the L-shaped block 155 to one side, which will move the baffle 154 and the insertion rod 153 and compress the second spring 157 until the insertion rod 153 disengages from the mounting handle 143, releasing the fixing of the mounting handle 143. Then press down the limiting rod 156 so that the limiting rod 156 inserts into the reserved hole in the locking block 158, which makes it easy for the operator to free their hands. At this time, the mounting handle 143 and the filter screen 144 can be pulled out from the mounting box 141 for easy cleaning and maintenance. After cleaning, insert the mounting handle 143 into the mounting box 141, pull the limiting rod 156 out of the locking block 158, and release the L-shaped block 155. At this time, the second spring 157 will push the baffle 154 and the insertion rod 153 to move, and the insertion rod 153 will re-insert into the mounting handle 143 to lock the mounting handle 143 and ensure the normal operation of the dust collection mechanism 13.

[0042] like Figure 7 As shown, the outer side of the baffle 154 is slidably connected to the inside of the outer shell 151, and the outer side of the L-shaped block 155 is slidably connected to the inside of the slide groove 152.

[0043] It should be noted that the sliding connection between the baffle 154 and the outer shell 151 enables the baffle 154 to move stably, and the slide groove 152 provides a limiting function for the L-shaped block 155.

[0044] like Figure 7 As shown, the bottom end of the limiting rod 156 is slidably connected inside the locking block 158, and one end of the insertion rod 153 passes through the mounting box 141 and is inserted into the mounting handle 143.

[0045] It should be noted that the limit rod 156, in cooperation with the locking block 158, can limit the L-shaped block 155, allowing the operator to free their hands, and the insertion rod 153 enables the installation handle 143 to be installed stably.

[0046] like Figure 7 As shown, one end of spring 157 is fixedly connected to the inner wall of the outer casing 151, and the other end of spring 157 is fixedly connected to the middle of the baffle 154.

[0047] It should be noted that spring 157 provides elastic force for the baffle 154 to reset.

[0048] The working principle of this utility model is as follows: When cleaning burrs on the motor core laminations, the laminations are first placed on the positioning mechanism 4 of the support base 3. The positioning mechanism 4 fixes the laminations. Then, motor 2 is started, which drives the support base 3 to rotate, conveying the laminations to the area to be cleaned. At the same time, cylinder 6 is started, which drives motor 7, slider 8, and deburring rod 11 to move downwards. The inclined block 121 on the right side of slider 8 pushes the roller 127 of control mechanism 12, causing push plate 125 to press switch 129, stopping motor 2. The positioning mechanism 4 is accurately positioned below the deburring rod 11. Then, motor 7 is started, which drives the fixed plate. 10 and deburring rod 11 rotate to clean the burrs on the edge of the punch. At the same time, the fan 142 of the dust collection mechanism 13 starts and adsorbs the dust generated during the cleaning process through the adsorption ring 147. The dust falls into the collection box 145 after being filtered by the filter screen 144. After cleaning is completed, the cylinder 6 drives the deburring rod 11 to move upward, the inclined block 121 disengages from the roller 127, the spring 128 pushes the movable rod 124 to reset, the push plate 125 leaves the switch 129, the motor 2 restarts, and the support base 3 rotates to send out the cleaned punch, completing one cleaning operation. The filter screen 144 can be easily removed for cleaning through the fixing component 15.
