Description

Technical Field

[0001] The invention relates to the technical field of grinding equipment, in particular to a metal power supply shell grinding equipment. Background Art

[0002] The power supply shell is a protective device of the power supply. Its function is to protect the internal components of the power supply from the external environment. Therefore, the power supply shell is mostly made of metal materials. The power supply shell made of metal materials has high strength and can provide sufficient mechanical protection to prevent external impact from causing damage to the internal components of the power supply. In addition, metal has good thermal conductivity, which helps to effectively dissipate the heat generated inside the power supply to the outside and prevent the device from overheating. The production of existing metal power supply casings requires the following steps: first, select suitable metal materials according to application requirements, such as metal plates such as aluminum, iron, and stainless steel, and then use cutting equipment to cut the metal plates according to design drawings; then use a bending machine to bend the cut plates to obtain the required parts of the metal power supply casing, and then weld the parts of the power supply casing to obtain the required metal power supply casing; and the welded metal power supply casing needs to be polished before surface coating or plating treatment can be performed; this is because the welded metal power supply casing will have welding marks formed by impurities such as welding slag and splashing molten metal particles at the weld seam, and polishing can effectively remove these welding marks, making the surface of the metal casing flat and smooth, increasing the contact area between the coating or plating and the metal power supply casing, and improving the mechanical adhesion between the coating or plating and the metal substrate, thereby extending the service life of the metal power supply casing; There are many types of metal power supply casing grinding equipment. Commonly used grinding equipment include grinding wire drawing machines and belt grinders. However, the belt grinder needs to replace the sanding belt frequently, which increases maintenance costs and downtime. The grinding rollers used in grinding wire drawing machines usually have a longer life. Therefore, when grinding large quantities of metal power supply casings, grinding wire drawing machines are often used to grind the metal power supply casings. When using the existing grinding and drawing machines, the user is required to manually press the grinding roller so that the grinding roller can be in close contact with the metal power supply casing, so that the grinding roller can effectively grind the metal power supply casing; however, the friction and shock force generated between the grinding roller and the metal power supply casing due to grinding will be transmitted to the user's pressing hand through the equipment. Long-term manual pressing will cause hand fatigue of the operator, especially when processing large quantities of metal power supply casings, which will increase the labor intensity of the user. In addition, due to the influence of human errors, the operator cannot ensure the constancy of the pressing force. Therefore, during the grinding process, it is easy to cause the pressure between the grinding roller and the metal power supply casing to be large and small, which will lead to uneven grinding effect, thereby affecting the overall grinding quality of the metal power supply casing. Summary of the invention

[0003] In order to make up for the deficiencies of the prior art, the present invention proposes a metal power supply casing polishing equipment.

DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0017] like Figures 1 to 9 As shown, the present invention includes the following embodiments: Embodiment 1:

[0018] A metal power supply casing polishing device, comprising: The frame 1 is provided with a mounting plate 11 slidably connected to the upper end of the frame 1; a driving motor 12 is fixedly installed on the upper end of the mounting plate 11; a bracket 2 is rotatably connected to one side of the mounting plate 11; a grinding roller 21 is rotatably connected to the end of the bracket 2 away from the mounting plate 11; the driving motor 12 drives the grinding roller 21 to rotate through a belt 251; a supporting platform 13 is provided below the mounting plate 11; the supporting platform 13 is connected to the frame 1 through an electric guide rail 14, Detection spring 231, the lower end of the bracket 2 is provided with a mounting groove 22; the side wall of the mounting groove 22 is provided with an arc groove 23; a slider 232 is slidably connected in the arc groove 23; the grinding roller 21 and the slider 232 are rotationally connected; the upper end wall of the arc groove 23 is inlaid with a pressure sensor 233; one end of the detection spring 231 is connected to the pressure sensor 233, and the other end is connected to the slider 232; a worm gear 15 is installed on one side of the bracket 2; the worm gear 15 is located above the mounting plate 11; a worm 151 is arranged on one side of the worm gear 15; the worm 151 is meshed with the worm gear 15; a driving unit is installed on the upper end of the mounting plate 11; the driving unit is used to drive the worm 151 to rotate.

[0019] In this embodiment, the support platform 13 is configured to be in the shape of a U-shaped letter "U". A splint 131 is slidably connected to the upper end of the support platform 13. The splint 131 is made of fluororubber material. There are two splints 131. The two splints 131 are fixedly connected to a hydraulic push rod 132 on one side away from each other. The hydraulic push rod 132 is fixedly connected to the support platform 13 on one side away from the splint 131. The hydraulic push rod 132 is located in the U-shaped cavity of the support platform 13.

[0020] In this embodiment, the driving unit includes a servo motor 16; the servo motor 16 is fixedly mounted on the upper end of the mounting plate 11; the output end of the servo motor 16 is fixedly connected to the worm 151; Specifically, when using the existing grinding and drawing machine, the user is required to manually press the grinding roller 21 so that the grinding roller 21 can be in close contact with the metal power supply shell, so that the grinding roller 21 can effectively grind the metal power supply shell; however, the friction shock force generated between the grinding roller 21 and the metal power supply shell due to grinding will be transmitted to the user's pressing hand through the equipment. Long-term manual pressing will cause hand fatigue of the operator, especially when processing a large number of metal power supply shells, which will increase the labor intensity of the user. In addition, due to the influence of human errors, the operator cannot ensure the constancy of the pressing force. Therefore, during the grinding process, it is easy to cause the pressure between the grinding roller 21 and the metal power supply shell to be large and small, which will lead to uneven grinding effect, thereby affecting the overall grinding quality of the metal power supply shell; In this regard, the present invention sets a detection spring 231 and a pressure sensor 233, so that when the driving motor 12 drives the worm wheel 15 to rotate through the worm 151, the worm wheel 15 can drive the bracket 2 to rotate, so that the bracket 2 drives the grinding roller 21 to generate a squeezing force on the metal power supply shell, thereby eliminating the need for the user to manually press the grinding roller 21, reducing the operator's hand fatigue and the user's labor intensity. In addition, the grinding roller 21 in a pressed state applies pressure to the pressure sensor 233 by squeezing the detection spring 231, so the operator can control the stable pressure applied by the grinding roller 21 to the metal shell through the data transmitted by the pressure sensor 233, thereby improving the grinding uniformity of the grinding roller 21 and improving the overall grinding quality of the metal power supply shell. In the initial state, the support platform 13 is located at one end of the electric guide rail 14 away from the frame 1, and the two hydraulic push rods 132 are in a retracted state. At this time, the hydraulic push rods 132 pull the two clamping plates 131 close to the two ends of the support platform 13. Then the user places the metal power supply casing on the support platform 13, and then controls the two hydraulic push rods 132 to extend, so that the hydraulic push rods 132 push the clamping plates 131 so that the clamping plates 131 are close to the metal power supply casing, so that the clamping plates 131 clamp the metal power supply casing. The clamping plates 131 are made of fluororubber material, so that the clamping plates 131 have a good friction coefficient and wear resistance, so that the clamping effect of the clamping plates 131 is good and the service life is long; at this time The metal power supply housing is fixed on the support platform 13, and then the user controls the electric guide rail 14 to operate, so that the electric guide rail 14 drives the support platform 13 to drive the metal power supply housing to move in the direction close to the frame 1, until the edge of the metal power supply housing with welding slag is located below the grinding roller 21, and the servo motor 16 is controlled to operate, so that the servo motor 16 can drive the worm 151 to rotate, so that the worm 151 drives the worm wheel 15 meshing with it to rotate, so that the worm wheel 15 can drive the bracket 2 connected thereto to rotate downward, so that during the downward rotation of the bracket 2, the bracket 2 can drive the grinding roller 21 in the mounting groove 22 to rotate synchronously, so that the grinding roller 21 is on the bracket 2 The grinding roller 21 is driven by the metal power supply shell and rotates in the direction close to the metal power supply shell until the grinding roller 21 contacts and presses against the metal power supply shell, thereby increasing the friction between the grinding roller 21 and the metal power supply shell. At this time, the grinding roller 21 pushes the slider 232 to slide upward along the arc groove 23 under the action of the blocking force of the metal power supply shell, so that the slider 232 squeezes the detection spring 231 along the arc groove 23, so that the detection spring 231 is squeezed and compressed; since one end of the detection spring 231 is connected to the slider 232 and the other end is connected to the pressure sensor 233, the slider 232 is also pushed by the compressed detection spring 231. Similarly, the pressure sensor 233 is also The compressed detection spring 231 pushes, and the pressure sensor 233 and the slider 232 are subjected to the same pushing force at this time; because the grinding roller 21 is blocked by the metal power supply shell and then squeezes the detection spring 231 through the slider 232, and the force is mutual, the pressing force between the grinding roller 21 and the metal power supply shell is the squeezing force on the detection spring 231; then the driving motor 12 is controlled to run, so that the driving motor 12 drives the grinding roller 21 to rotate through the belt 251, and at this time the user pushes the bracket 2, so that the bracket 2 can drive the mounting plate 11 to make a linear displacement along the frame 1 on the one hand, and on the other hand, the bracket 2 drives the grinding roller 21 to move synchronously;The rotating grinding roller 21 grinds the welding slag on the surface of the metal power supply shell, so that the protruding welding slag on the metal power supply shell is smoothed by the grinding roller 21. In the process of grinding the welding slag by the grinding roller 21, the grinding roller 21 will slide downward along the arc groove 23, so that the elastic force of the detection spring 231 is released. At this time, the pushing force of the detection spring 231 on the grinding roller 21 is reduced, so that the clamping force between the grinding roller 21 and the metal power supply shell is gradually reduced, thereby preventing the grinding roller 21 from having too much pressure between the grinding roller 21 and the metal power supply shell after the welding slag is polished off, thereby preventing the metal power supply shell from being over-polished, thereby ensuring the safety of the machine. The surface quality of the metal power supply shell is protected; the grinding effect of the grinding roller 21 on the metal power supply shell is also improved; the practicality of the present invention is improved; by setting the center of the arc groove 23 to be located at the axis center of the output shaft of the drive motor 12, the slider 232 drives the grinding roller 21 to slide in the arc groove 23, and the grinding roller 21 can always rotate around the axis center of the output shaft of the drive motor 12, avoiding the problem of the belt 251 being broken or loosened due to the change in the distance between the grinding roller 21 and the output shaft of the drive motor 12, so that the distance between the grinding roller 21 and the output shaft of the drive motor 12 can remain unchanged , so that when the grinding roller 21 slides along the arc groove 23, the grinding roller 21 and the output shaft of the drive motor 12 are always stably transmitted through the belt 251, thereby ensuring that the drive motor 12 can effectively and stably drive the grinding roller 21; improve the grinding effect of the grinding roller 21 on the metal power supply shell; the practicality of the present invention is effectively improved. At the same time, when the grinding roller 21 is grinding the oxide layer such as welding slag or rust on the metal power supply shell, the pressure sensor 233 can realize the pressure monitoring between the grinding roller 21 and the metal power supply shell; to ensure that the grinding roller 21 can pass the correct The pressure grinds the oxide layers such as welding slag or rust on the metal power supply shell, which helps to ensure uniform grinding and avoid the problem of local over-grinding or insufficient wear, thereby improving the finish and consistency of the processed metal power supply shell surface; greatly improving the practical application effect of the present invention; when the grinding surface of the metal power supply shell needs to be replaced, it is only necessary to control the hydraulic push rod 132 to retract, and then the user changes the surface of the metal power supply shell on the support table 13, and then controls the hydraulic push rod 132 to push the clamping plate 131 to clamp the metal power supply shell, and then a new round of grinding can be performed on the changed metal power supply shell. ;

[0021] In this embodiment, a positioning rod 152 is fixedly connected to the upper end of the mounting plate 11; the worm wheel 15 is in sliding contact with the positioning rod 152; a support spring 153 is provided between the worm wheel 15 and the bracket 2; one end of the support spring 153 is fixedly connected to the worm wheel 15, and the other end is in rotational contact with the bracket 2; an engagement groove 27 is provided on one side of the bracket 2; and teeth 154 are fixedly connected to the surface of the worm wheel 15.

[0022] In this embodiment, the worm wheel 15 is rotatably connected to a rotating ring 155 on a side close to the bracket 2; a U-shaped plate 28 is fixedly connected to the upper end of the bracket 2; a handle 281 is provided above the grinding roller 21; the handle 281 is slidably connected to the U-shaped plate 28; the handle 281 is fixedly connected to the rotating ring 155 via a steel wire rope 29; Specifically, when the worm wheel 15 and the worm 151 are used to drive the bracket 2 to rotate, the transmission efficiency of the worm wheel 15 and the worm 151 is low, so that the rotation speed of the worm wheel 15 and the worm 151 is slow. This will affect the grinding efficiency of the metal power supply shell when processing a large number of metal power supply shells. For this reason, the present invention sets the connection between the worm wheel 15 and the bracket 2 as a detachable connection; in the initial state, the worm wheel 15 is supported by the support spring 153 and is located on one side of the bracket 2. At this time, the worm wheel 15 is in sliding contact with the positioning rod 152. At this time, the teeth 154 on the surface of the worm wheel 15 are located on one side of the bracket 2, that is, the worm wheel 15 and the bracket 2 are in a separated state; when the user controls the electric guide rail 14 to drive the support platform 1 When the bracket 2 is located below the grinding roller 21, the user pushes the U-shaped plate 28. Since the U-shaped plate 28 is located at one end of the bracket 2 close to the grinding roller 21, the pushed U-shaped plate 28 can drive the bracket 2 to rotate downward. Since the worm gear 15 is in a separated state from the bracket 2, the bracket 2 will not drive the worm gear 15 to rotate during the downward rotation of the bracket 2, so that the worm gear 15 will not interfere with the bracket 2 rotating downward, so that the user can quickly push the bracket 2 to drive the grinding roller 21 to rotate to the metal power supply housing, thereby eliminating the need for the servo motor 16 to drive the bracket 2 to drive the grinding roller 21 to rotate to the metal power supply housing through the worm gear 15 and the worm 151, which not only reduces the servo motor 16 driving the bracket 2 to rotate, but also reduces the servo motor 16 driving the bracket 2 to rotate. The time for the frame 2 to rotate downward improves the efficiency of grinding the metal power supply shell, and also reduces the running time of the servo motor 16, reduces the consumption of electric energy, and effectively improves the use of the present invention; when the grinding roller 21 contacts the metal power supply shell, the user holds the handle 281 and pulls the handle 281 close to the U-shaped plate 28, so that the handle 281 can pull the rotating ring 155 close to the bracket 2 through the wire rope 29 during the process of approaching the U-shaped plate 28; because the rotating ring 155 is in rotational contact with the worm gear 15, the rotating ring 155 pulled by the wire rope 29 can drive the worm gear 15 to move in the direction close to the bracket 2, so that the worm gear 15 drives the surface teeth 154 to approach the meshing groove 27 on one side of the bracket 2, and the worm gear 15 is in rotational contact with the worm gear 15. During the movement of the wheel 15, the worm wheel 15 is always in meshing state with the worm 151; when the teeth 154 are facing the meshing groove 27, the worm wheel 15 pulled by the wire rope 29 can drive the teeth 154 to insert into the meshing groove 27; if the teeth 154 are not facing the meshing groove 27, the user needs to control the servo motor 16 to operate, so that the servo motor 16 drives the worm wheel 15 to rotate through the worm 151, so that the worm wheel 15 drives the teeth 154 on the surface to rotate, so that the teeth 154 can rotate to face the meshing groove 27 under the drive of the worm wheel 15, so that the wire rope 29 can pull the worm wheel 15 to move through the swivel 155, so that the worm wheel 15 drives the teeth 154 to insert into the meshing groove 27;Since one end of the support spring 153 is fixedly connected to the worm wheel 15, and the other end is in rotational contact with the bracket 2, during the rotation of the worm wheel 15, the worm wheel 15 can drive the support spring 153 to rotate relative to the bracket 2, thereby preventing the support spring 153 from being driven by the worm wheel 15 and causing torsional damage between the bracket 2 and the worm wheel 15, so as to ensure that the support spring 153 can be used normally and stably, thereby improving the service life and use effect of the support spring 153; after the worm wheel 15 is plugged into the meshing groove 27 of the bracket 2 through the teeth 154, the servo motor 16 is controlled to run at this time, so that the servo motor 16 can drive the worm wheel 15 through the worm 151 to drive the bracket 2 to rotate downward, so that the bracket 2 can drive the grinding roller 21 Continue to rotate downward, so that the grinding roller 21 is pressed against the metal power supply housing, so that the grinding roller 21 pushes the slider 232 connected to it for rotation to squeeze the detection spring 231 and slide along the arc groove 23. At this time, the pressure sensor 233 detects the pressing force between the grinding roller 21 and the metal power supply housing; since an operation panel is installed on one side of the frame 1, the pressure sensor 233 can transmit the detected pressure to the operation panel in the form of an electrical signal for the user to observe; when the pressure detected by the pressure sensor 233 reaches the set value, the operation panel controls the servo motor 16 to stop; and then controls the drive motor 12 to drive the grinding roller 21 to rotate through the belt 251 and grind the metal power supply housing; For the metal power supply casing that needs to be repaired, since there is a defect of local cracking at the welding part, only the cracked part needs to be repaired. For the metal power supply casing that has been repaired, the user only needs to grind the welding slag at the repaired part. Therefore, the user needs to manually press the grinding roller 21 to grind the repaired part of the metal power supply casing, so as to prevent the grinding roller 21 from excessively grinding the non-welding slag part of the metal power supply casing. For this, the user only needs to push the bracket 2 through the U-shaped plate 28 to drive the grinding roller 21 to contact the repaired part of the metal power supply casing, and there is no need to pull the handle 281, so that the handle 281 pulls the worm gear 15 and the bracket 2 through the wire rope 29 to plug it. Therefore, the user only needs to press the bracket 2 to realize the grinding roller 21 to accurately grind the repaired part of the metal power supply casing. This allows the present invention to not only perform pressure-regulated voltage-stabilizing grinding on the metal power supply casing with more welding slag accumulation, but also perform manual pressure-pressing grinding on the repaired metal power supply casing with less welding slag, thereby further improving the practicality of the present invention.

After the user pushes the support platform 13 with the metal power supply shell installed to the bottom of the grinding roller 21, the user first pushes the U-shaped plate 28 to drive the bracket 2 to rotate downward, so that the grinding roller 21 contacts the metal power supply shell, and then holds the handle 281 so that the handle 281 can pull the worm through the wire rope 29. The wheel 15 squeezes the supporting spring 153 and approaches the bracket 2, so that the worm wheel 15 meshes with the meshing groove 27 of the bracket 2 through the teeth 154 on the surface, so that the worm wheel 15 is plugged into the bracket 2; then the user releases the grip 281, and controls the electromagnetic sheet 243 to be energized, so that the electromagnetic sheet 243 can absorb the connecting rod 24 and squeeze the connecting spring 242 into the connecting groove 241, so that the connecting rod 24 entering the connecting groove 241 extends out of the rectangular groove 252 and away from the transmission rod 25, that is, at this time, the driving motor 12 and the transmission rod 25 are in a separated state; because the end of the insertion rod 261 away from the transmission belt 18 is located in the rectangular groove 252, when the connecting rod 24 enters the connecting groove 241, the connecting rod 24 can generate an extrusion force on the hydraulic oil in the connecting groove 241, so that the pressure of the hydraulic oil increases, so that a pressure difference is generated at both ends of the plug rod 261, so that the plug rod 261 moves along the circular groove 26 away from the rectangular groove 252 under the push of the pressure difference, so that the plug rod 261 extends out of the circular groove 26 and enters the slot 181 on the inner wall of the transmission belt 18, so that the output end of the drive motor 12 is meshed with the transmission belt 18 through the plug rod 261; because the bevel gear shaft 17 is meshed with the transmission belt 18 through the protrusion 262 on the surface, the drive motor 12 is meshed with the transmission belt 18. The motor 12 can drive the bevel gear shaft 17 to rotate through the transmission belt 18, so that the bevel gear shaft 17 drives the bevel gear ring 171 meshing therewith to rotate, so that the rotating bevel gear ring 171 can drive the worm 151 fixed thereto to rotate, so that the worm 151 can drive the worm wheel 15 to rotate, so that the worm wheel 15 can drive the bracket 2 to rotate downward, so that the grinding roller 21 is driven by the bracket 2 to squeeze the metal power supply housing, so that the grinding roller 21 is affected by the blocking force of the metal power supply housing to push the slider 232 to slide along the arc groove 23, so that the slider 232 squeezes the pressure sensor 233 through the detection spring 231;Since an operation panel is installed on one side of the frame 1, the pressure sensor 233 can transmit the detected pressure to the operation panel in the form of an electrical signal for the user to observe. When the pressure detected by the pressure sensor 233 reaches the set value, the operation panel controls the drive motor 12 to stop, and at the same time controls the electromagnetic sheet 243 to cut off the power, so that the connecting rod 24 extends out of the connecting slot 241 under the push of the restoring force of the connecting spring 242 and contacts the transmission rod 25. If the connecting rod 24 is not aligned with the rectangular slot 252, the connecting rod 24 is located at the notch of the rectangular slot 252; at this time, the insertion rod 261 enters the circular slot 26 by entering the extending slot 181, that is, at this time, the output shaft of the drive motor 12 is not engaged with the transmission belt 18. At this time, the output shaft of the drive motor 12 is controlled to drive the connecting rod 24 to rotate, so that The connecting rod 24 can be rotated to a state aligned with the rectangular groove 252. At this time, the connecting rod 24 is inserted into the rectangular groove 252 under the push of the restoring force of the connecting spring 242. Since the transmission belt 18 is made of PTFE material, the surface of the transmission belt 18 is smooth and the friction coefficient is low, so that the transmission belt 18 and the output shaft of the drive motor 12 are in sliding contact, so that after the electromagnetic sheet 243 is powered off, the drive motor 12 will not drive the bevel gear shaft 17 to rotate through the transmission belt 18; after the connecting rod 24 is inserted into the rectangular groove 252 of the transmission rod 25, the drive motor 12 is controlled to continue to run, so that the drive motor 12 can drive the transmission rod 25 to rotate, so that the transmission rod 25 can drive the grinding roller 21 connected to its belt drive to rotate through the belt 251, so that the grinding roller 21 grinds the metal power supply housing; The present invention sets a connecting rod 24 so that when the connecting rod 24 is attracted by the electromagnetic sheet 243 and enters and exits the connecting groove 241, the driving motor 12 can be connected to and separated from the transmission rod 25, thereby separately driving the bracket 2 and the grinding roller 21. There is no need to add additional motor components, thereby reducing the number of motor components used in the present invention. On the one hand, it reduces the failure points of the circuit system and facilitates rapid maintenance by operators. On the other hand, it also reduces the demand for maintenance and replacement of motor components, reduces the cost of long-term operation, and further improves the practicality of the present invention.
