Description

Technical Field

[0001] This utility model relates to the field of charging pile frame processing technology, and more specifically to a grinding device for charging pile frame. Background Technology

[0002] Some new energy charging piles have a three-layer casing, with cover plates on both sides and a middle frame for fixing the cover plates.

[0003] For example, Chinese patent CN207201108U discloses a portable charging pile shell that can ensure the internal electronic components are intact, thereby ensuring the quality and stability of the product. During the production process, the frame needs to be ground around the joints to eliminate defects such as burrs. However, existing grinding devices are mostly single-sided grinding, requiring multiple grinding operations around the edges. At the same time, the position of the frame also needs to be adjusted. Burrs during the adjustment process can easily scratch workers, causing injuries. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a grinding device for the middle frame of a charging pile to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a grinding device for the middle frame of a charging pile, comprising a frame and a middle frame body. A three-axis linear module is fixed between the inner walls of both sides of the frame by bolts. The moving end of the three-axis linear module is fixed to a mounting frame by bolts. A second motor is fixed to the bottom inner wall of the mounting frame by bolts. The output shaft of the second motor passes through the mounting frame and is fixed to a grinding head by bolts. A first motor is fixed to one side of the frame by bolts. The output shaft of the first motor passes through the frame and is fixed to a bidirectional lead screw by a coupling. Two sliders are threaded to the outer circumference of the bidirectional lead screw. A clamping plate is welded to one side of the two sliders, and the middle frame body is located between the two clamping plates. A stop is fixed to the bottom inner wall of the frame by bolts.

[0006] As a further embodiment of this utility model, two door panels are rotatably connected to one side of the frame, and a heat dissipation component is provided on one side of the frame to connect the interior of the frame with the external air.

[0007] As a further embodiment of this utility model, the heat dissipation component includes two air inlets on one side of the frame, and air outlets on one side of both door panels, and an air duct can be formed between the air inlets and air outlets.

Filter plates are fixed to the inner walls of the two air inlets and outlets by bolts.

[0009] As a further embodiment of this utility model, the bottom inner wall of the frame is provided with a plurality of guide grooves that penetrate both sides of the frame, and the guide grooves are inclined from the middle to both sides.

[0010] As a further embodiment of this utility model, a baffle and a protective frame are welded between the inner walls of both sides of the frame, and the protective frame and the baffle are fixed together.

[0011] As a further embodiment of this utility model, there is a gap between the protective frame and the bottom of the frame body, and the height of the gap is the same as the height of the clamping plate.

[0012] As a further embodiment of this utility model, both sides of the mounting bracket are fixed with water spray pipes that are connected to an external water pump by bolts, and the water spray position of the water spray pipes points towards the edge grinding head.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1-3This utility model provides a grinding device for the middle frame of a charging pile, including a frame 1 and a middle frame body 2. A three-axis linear module 7, model FSL120XYZ-X, is bolted between the inner walls of both sides of the frame 1. The moving end of the three-axis linear module 7 is bolted to a mounting bracket 8. A second motor 14 is bolted to the bottom inner wall of the mounting bracket 8. The output shaft of the second motor 14 passes through the mounting bracket 8 and is bolted to a grinding head 16. Both sides of the mounting bracket 8 are bolted to... A water spray pipe 15 connected to an external water pump is fixed, and the spray position of the water spray pipe 15 is directed towards the grinding head 16. When the grinding head 16 is in use, the external water pump is started, so that coolant is sprayed from the water spray pipe 15 onto the grinding head 16 to cool it down. A first motor 12 is fixed to one side of the frame 1 by bolts. The output shaft of the first motor 12 passes through the frame 1 and is fixed to a double-acting lead screw 9 by a coupling. Two sliders 11 are threaded to the outer circumference of the double-acting lead screw 9. One side of the two sliders 11 is welded The device has clamping plates 10, with the middle frame body 2 located between the two clamping plates 10. A baffle 21 is fixed to the bottom inner wall of the frame 1 by bolts. In use, the middle frame body 2 is placed between the two clamping plates 10, with one side of the middle frame body 2 in contact with the baffle 21. The first motor 12 is started, driving the bidirectional lead screw 9 to rotate, causing the two sliders 11 to move towards each other. The sliders 11 also cause the two clamping plates 10 to move towards the middle frame body 2 simultaneously, thus clamping the middle frame body 2 and positioning it in the middle of the bottom of the frame 1. The second motor 14 is started, driving the grinding head 16 to rotate. The position of the grinding head 16 is changed by the three-axis linear module 7, allowing the rotating grinding head 16 to grind the edges of the middle frame body 2. This allows for grinding of all four sides in one operation. By simply flipping the device, the grinding operation on both sides of the middle frame body 2 can be completed, greatly reducing the chance of workers coming into contact with the middle frame body 2, thereby reducing the risk of injury to workers and improving the protective effect of the device.

[0023] In this invention, two door panels 4 are rotatably connected to one side of the frame 1. Closing the door panels 4 creates a sealed space between the frame 1 and the door panels 4, preventing debris generated during edge grinding from flying out of the frame 1 and causing injury to personnel, thus further improving the protective effect of the device. A heat dissipation assembly is provided on one side of the frame 1 to connect the interior of the frame 1 with the external air. The heat dissipation assembly includes two air inlets 17 on one side of the frame 1, and air outlets 5 on one side of each of the two door panels 4. An air duct can be formed between the air inlets 17 and the air outlets 5. Two air inlets are bolted to one side of the frame 1. The air guide frames 17 are connected. One side of each air guide frame 18 is fixed with a fan 19 by bolts. The inner walls of the two air inlets 17 and the air outlets 5 are fixed with filter plates 6 by bolts. The filter plates 6 filter the air in the air inlets 17 and the air outlets 5, which not only prevents impurities from entering the frame 1, but also prevents debris from leaving the frame 1. When the fan 19 is started, the fan 19 blows air through the air guide frames 18 and the air inlets 17 into the sealed space formed between the frame 1 and the door panel 4, and causes the internal airflow to be discharged from the air outlets 5, thus completing the replacement of the internal hot air and improving the heat dissipation effect of the device.

[0024] The frame 1 has multiple guide channels 3 extending through both sides of its bottom inner wall. The guide channels 3 are inclined from the middle to both sides. The coolant sprayed from the water spray pipe 15 falls on the bottom inner wall of the frame 1 and is discharged into the frame 1 through the guide channels 3, preventing the coolant from accumulating on the bottom inner wall of the frame 1. A baffle 13 and a protective frame 20 are welded between the inner walls of the two sides of the frame 1, and the protective frame 20 is fixed to the baffle 13. The baffle 13 is inclined to block the splashing coolant, making it less likely for the coolant to splash onto the three-axis linear module 7, thus improving the service life of the three-axis linear module 7. The protective frame 20 protects the bidirectional lead screw 9. There is a gap between the protective frame 20 and the bottom of the frame 1, and the height of the gap is the same as the height of the clamping plate 10, allowing the clamping plate 10 to move normally. At the same time, it allows airflow to pass through the gap, thereby blowing debris toward the door panel 4 and preventing debris from entering the gap between the protective frame 20 and the frame 1.

[0025] The working principle of this utility model is as follows: In use, the middle frame body 2 is placed between two clamping plates 10, with one side of the middle frame body 2 in contact with the stop 21. The first motor 12 is started, driving the bidirectional lead screw 9 to rotate, causing the two sliders 11 to move towards each other. The sliders 11 also cause the two clamping plates 10 to move simultaneously towards the middle frame body 2, thus clamping the middle frame body 2 and positioning it in the middle of the bottom of the frame 1. The second motor 14 is then started, driving the grinding head 16 to rotate. The position of the grinding head 16 is changed by the three-axis linear module 7, causing the rotating grinding head 16 to contact the middle frame body 2, thus grinding the middle frame body. When the body 2 is being edged, the external water pump is started to spray coolant from the water spray pipe 15 onto the edged head 16 to cool it down. At the same time, the fan 19 is started, and the fan 19 blows air through the air guide frame 18 and the air inlet 17 into the sealed space formed between the frame 1 and the door panel 4, and the internal airflow is discharged from the air outlet 5 to replace the internal hot air. It can directly edge the four sides in one go. It only needs to be flipped to achieve edge grinding on both sides of the middle frame body 2, which greatly reduces the chance of workers coming into contact with the middle frame body 2, thereby reducing the risk of worker injury and improving the protective effect of the device.

[0026] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
