Description

Technical Field

[0001] This utility model relates to the field of inverter chassis processing technology, and in particular to a cutting device for inverter chassis processing. Background Technology

[0002] A frequency converter mainly consists of rectification (AC to DC), filtering, inversion (DC to AC), braking unit, drive unit, detection unit, and microprocessor unit. The frequency converter adjusts the output voltage and frequency by switching its internal IGBTs, providing the required power voltage according to the actual needs of the motor, thereby achieving energy saving and speed regulation. In addition, the frequency converter has many protection functions, such as overcurrent, overvoltage, and overload protection. The frequency converter is installed in a chassis. Different models of frequency converters have different chassis dimensions. The chassis is assembled from cut steel; however, existing cutting devices are inconvenient for adjusting the cutting position and require further improvement.

[0003] Chinese patent document CN209936029U discloses a cutting device for processing inverter chassis. It features a worktable with support columns connected to its four corners. A transmission mechanism is located on the top left side of the worktable, and a cutting mechanism is connected to the top right end of the transmission mechanism. A fixed shaft is connected to the top of the worktable, and a support platform is rotatably connected to the upper end of the fixed shaft. The support platform is located below the cutting mechanism, and a limiting mechanism is provided at the front end of the support platform. This invention has a reasonable structural design. The cutting mechanism cuts steel plates using a hydraulic telescopic rod, and the cutting distance can be adjusted using an electric push rod. After the support platform disengages from the limiting block, it can rotate around the fixed shaft. The cutting angle can be adjusted without the operator moving the steel plate, thus improving work efficiency.

[0004] The existing technology has the following problems:

[0005] When adjusting the angle of the support platform and the workpiece in the above-mentioned device, the limiting screw needs to be rotated twice in opposite directions, which is time-consuming. In addition, the debris generated during cutting will be left in the four sets of sliding grooves, which requires manual cleaning, making it not very practical. Secondly, in the above-mentioned device, the surface of the workpiece cannot be washed and cooled during cutting, which can easily cause damage to the cutting disc and the retention of impurities, reducing the processing quality of the workpiece.

Adjusting plates are fixedly installed at the front ends of the two pull rods. Arc-shaped racks are fixedly installed at the rear ends of the two pull rods. The rear side of the arc-shaped rack meshes with the outer surface of the adjusting gear.

[0010] The rinsing and cooling assembly includes a water tank that can be filled with water. The upper end of the water tank is fixedly installed at the left rear position of the lower end of the workbench. A water pump is fixedly installed at the middle rear side of the water tank. A hose is fixedly installed at the output end of the water pump. A connecting sleeve is rotatably connected to the upper right side of the telescopic part of the electric telescopic rod. The top of the outer wall of the hose near the electric cutting disc is fixedly connected to the inner wall of the connecting sleeve. A gear is fixedly sleeved on the rear side of the outer wall of the connecting sleeve. A cylinder is fixedly installed on the right side of the telescopic part of the electric telescopic rod.

[0011] Preferably, the front part of the outer wall of both pull rods is movably sleeved with an elastic element.

[0012] Preferably, a collection box is fixedly installed on the lower right side of the workbench. The collection box is connected to the guide cover. A movable groove is opened on the front side of the collection box, and collection boxes are slidably connected to the left and right sides of the inner wall of the movable groove.

[0013] Preferably, the fixing mechanism includes an arc-shaped fixing plate, the lower end of which is fixedly connected to the upper edge of the guide cover, and a limit screw is threadedly connected to the side of the arc-shaped fixing plate away from the axis of the guide cover.

[0014] Preferably, two guide rods are slidably connected to the side of the arc-shaped fixing plate away from the axis of the guide cover, penetrating the side of the arc-shaped fixing plate near the axis of the guide cover.

Through the cooperation of a guide hood, a fixing mechanism, an adjusting gear, a mounting plate, a pull rod, an adjusting plate, an arc-shaped rack, elastic elements, a collection box, and a collection container, the cutting position can be quickly changed according to the workpiece's processing position. Pulling the adjusting plate forward causes the two pull rods to press against the two elastic elements and move forward, thus disengaging the arc-shaped rack from the adjusting gear. After rotating the entire guide hood to the appropriate position, releasing the adjusting plate causes the arc-shaped rack to return to its original position through the elastic restoring force of the two elastic elements. The tooth structure on the rear side of the arc-shaped rack locks the adjusting gear, thus quickly restricting the guide hood after rotation at a certain angle. Simultaneously, debris generated during workpiece cutting falls into the collection box through several drain troughs, ensuring a clean processing environment. This process not only allows for changing the workpiece's cutting position according to different cutting needs but also immediately fixes it after the guide hood rotates, saving processing time.

[0019] 2. This utility model provides a cutting device for processing inverter chassis. Through the cooperation of a water tank, water pump, hose, connecting sleeve, gear, cylinder, rack, and limit rod, it can cool the surface of the electric cutting disc and also wash away the chips and workpieces on the upper part of the guide cover. The water pump pumps cooling water from the water tank into the hose, which sprays water onto the operating electric cutting disc to prevent overheating. Simultaneously, when it is necessary to wash the upper part of the guide cover and the workpiece, the output end of the cylinder can drive the rack to move vertically. The gear, through meshing with the rack, drives the connecting sleeve to rotate. The connecting sleeve can drive the hose to rotate left or right by a certain angle, allowing the hose to avoid the cutting disc of the electric cutting disc and wash the upper part of the guide cover. Any remaining chips on the upper part can then flow with the water into the collection box for easy disposal. The above process realizes multiple uses of cooling water and improves the efficiency of material processing and waste collection, making it highly practical. Attached Figure Description

[0027] 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.

[0028] like Figures 1-6 As shown, a cutting device for processing inverter chassis includes a worktable 1. An orientation adjustment component 2 is movably connected to the upper right side of the worktable 1. A linear moving mechanism 11 is fixedly installed at the edge of the upper left side of the worktable 1. A moving plate 12 is movably connected to the top of the linear moving mechanism 11. A spiral moving mechanism 13 is movably connected to the upper and lower right sides of the moving plate 12. An electric telescopic rod 14 is threadedly connected to the right side of the spiral moving mechanism 13. An electric cutting disc 15 is fixedly installed at the bottom of the telescopic part of the electric telescopic rod 14. A flushing and cooling component 3 is fixedly installed at the rear position of the lower left side of the worktable 1.

[0029] The orientation adjustment assembly 2 includes a guide cover 21. The bottom outer wall of the guide cover 21 is rotatably connected to the inner wall of the upper right side of the workbench 1. The upper end of the guide cover 21 is provided with several linearly arranged draining grooves 22. Four fixed mechanisms 23 arranged in a ring are fixedly installed at the upper edge of the guide cover 21. An adjusting gear 24 is fixedly sleeved on the bottom outer wall of the guide cover 21. An installation plate 25 is fixedly installed on the front right side of the workbench 1. Pull rods 26 that penetrate the front of the installation plate 25 are slidably connected to the left and right sides of the front side of the installation plate 25. An adjusting plate 27 is fixedly installed at the front end of the two pull rods 26. An arc-shaped rack 28 is fixedly installed at the rear end of the two pull rods 26. The rear side of the arc-shaped rack 28 meshes with the outer surface of the adjusting gear 24.

[0030] The rinsing and cooling assembly 3 includes a water tank 31 that can be filled with water. The upper end of the water tank 31 is fixedly installed at the left side of the lower rear end of the workbench 1. A water pump 32 is fixedly installed at the middle of the rear side of the water tank 31. A hose 33 is fixedly installed at the output end of the water pump 32. A connecting sleeve 34 is rotatably connected to the upper right side of the extension and retraction point of the electric telescopic rod 14. The top of the outer wall of the hose 33 near the electric cutting disc 15 is fixedly connected to the inner wall of the connecting sleeve 34. A gear 35 is fixedly sleeved on the rear side of the outer wall of the connecting sleeve 34. A cylinder 36 is fixedly installed on the right side of the extension and retraction point of the electric telescopic rod 14. A rack 37 is fixedly installed at the output end of the cylinder 36. The left side of the rack 37 meshes with the outer surface of the gear 35.

[0031] The orientation adjustment component 2 allows for rapid switching of the cutting orientation according to the workpiece's processing position. Pulling the adjustment plate 27 forward causes the two pull rods 26 to press against the two elastic elements 29 and move forward, thus disengaging the arc-shaped rack 28 from the adjusting gear 24. After rotating the entire guide cover 21 to the appropriate position, the adjustment plate 27 is released. The adjustment plate 27, through the elastic restoring force of the two elastic elements 29, drives the arc-shaped rack 28 to return to its original position. The tooth structure on the rear side of the arc-shaped rack 28 locks the adjusting gear 24, thereby quickly restricting the guide cover 21 after rotation at a certain angle. Simultaneously, debris generated during workpiece cutting falls into the collection box 210 through several drain troughs 22, ensuring a clean processing environment. This process not only allows for changing the workpiece's cutting orientation according to different cutting requirements but also immediately fixes it after the guide cover 21 rotates, saving processing time. The rinsing and cooling assembly 3 not only cools the surface of the electric cutting disc 15, but also washes away the chips and workpieces on the upper part of the guide cover 21. The water pump 32 pumps cooling water from the water tank 31 into the hose 33, which sprays water onto the working electric cutting disc 15 to prevent overheating. Simultaneously, when rinsing the upper part of the guide cover 21 and the workpiece is required, the output end of the cylinder 36 drives the rack 37 to move vertically. The gear 35, through meshing with the rack 37, drives the connecting sleeve 34 to rotate. The connecting sleeve 34 can then rotate the hose 33 to the left or right by a certain angle, allowing the hose 33 to avoid the cutting disc of the electric cutting disc 15 and rinse the upper part of the guide cover 21. Any remaining chips on the upper part can then flow with the water into the collection box 211 for easy disposal. This process realizes multiple uses for the cooling water and improves the efficiency of material handling and waste collection, demonstrating strong practicality.

[0032] like Figure 4 As shown, elastic elements 29 are movably sleeved on the front part of the outer wall of both pull rods 26.

[0033] Both elastic elements 29 are springs, which play a resetting role on the adjusting plate 27 and the two pull rods 26. The resetting process ensures that the arc-shaped rack 28 and the adjusting gear 24 can re-mesh, thereby fixing the guide cover 21 in the required position.

[0034] like Figure 4 As shown, a collection box 210 is fixedly installed on the lower right side of the workbench 1. The collection box 210 is connected to the guide cover 21. A moving groove is opened on the front side of the collection box 210, and a collection box 211 is slidably connected to the left and right sides of the inner wall of the moving groove.

[0035] The collection box 211 is used to collect sewage and debris falling from the guide hood 21. During subsequent processing, it can be slid out of the moving tank.

[0036] like Figure 4As shown, the fixing mechanism 23 includes an arc-shaped fixing plate 231. The lower end of the arc-shaped fixing plate 231 is fixedly connected to the upper edge of the guide cover 21. A limit screw 232 is threadedly connected to the side of the arc-shaped fixing plate 231 away from the axis of the guide cover 21. A clamping plate 233 is rotatably connected to the end of the limit screw 232 near the axis of the guide cover 21.

[0037] Rotating the four limit screws 232 and the four clamping plates 233 can clamp and fix the workpiece in four directions, ensuring the stability of cutting.

[0038] like Figure 4 As shown, two guide rods 234 are slidably connected to the side of the arc-shaped fixing plate 231 away from the axis of the guide cover 21. The two guide rods 234 are fixedly connected to the side of the clamping plate 233 away from the axis of the guide cover 21 at one end. The two guide rods 234 are located on both sides of the limiting screw 232.

[0039] The two adjacent guide rods 234 serve to guide and limit the corresponding clamping plates 233.

[0040] like Figure 6 As shown, a limit rod 38 is fixedly installed at the lower end of the rack 37, and a cylindrical groove matching the limit rod 38 is provided at the upper rear part of the telescopic part of the electric telescopic rod 14.

[0041] The design of the limit rod 38 and the cylindrical slide groove ensures the stability and accuracy of the rack 37 during movement.

[0042] like Figure 6 As shown, the hose 33 has an L-shaped structure, and the vertical end of the hose 33 is located in front of the electric cutting disc 15.

[0043] The L-shaped design of the hose ensures that the water flow can be sprayed onto the surface of the electric cutting disc 15.

[0044] The working principle of this utility model is as follows: The linear moving mechanism 11 and the spiral moving mechanism 13 are common mechanisms, and their principles are the same. They both drive the corresponding moving parts to move by rotating a lead screw. The linear moving mechanism 11 can drive the moving plate 12 to move back and forth, and the spiral moving mechanism 13 can drive the electric telescopic rod 14 to move up and down. The electric telescopic rod 14 can drive the electric cutting disc 15 to move left and right. This process provides the electric cutting disc 15 with moving space, which facilitates its cutting of workpieces of different sizes.

[0045] The workpiece is placed on the upper end of the guide cover 21 beforehand. The four limit screws 232 are rotated, and the four clamping plates 233 can clamp and fix the workpiece in four directions. If the processing position of the workpiece needs to be changed quickly, the adjusting plate 27 is pulled forward, so that the two pull rods 26 squeeze the two elastic elements 29 and move forward, thereby causing the arc-shaped rack 28 to disengage from the adjusting gear 24. After rotating the entire guide cover 21 to the appropriate position, the adjusting plate 27 is released. The adjusting plate 27 drives the arc-shaped rack 28 to return to its original position through the elastic restoring force of the two elastic elements 29. The tooth structure on the rear side of the arc-shaped rack 28 locks the adjusting gear 24, so that the guide cover 21 can be quickly restricted after rotating a certain angle. At the same time, the debris generated during the workpiece cutting process falls into the collection box 210 through several draining grooves 22, ensuring the cleanliness of the processing environment. At the same time, the water pump 32 starts, and its output end pumps the cooling water in the water tank 31 into the hose 33. The hose 33 moves with the electric cutting disc 15 and sprays the cooling water onto the working electric cutting disc 15 to prevent it from overheating.

[0046] Simultaneously, when it is necessary to rinse the upper end of the guide cover 21 and the workpiece, the output end of the cylinder 36 can drive the rack 37 to move vertically. The gear 35, through meshing with the rack 37, drives the connecting sleeve 34 to rotate. The connecting sleeve 34 can drive the hose 33 to rotate to the left or right at a certain angle, so that the hose 33 can avoid the cutter head of the electric cutting disc 15 and rinse the upper end of the guide cover 21, allowing the residual debris at the upper end to flow into the collection box 211 with the water flow for easy disposal. The above rinsing steps can be used during workpiece processing and also after workpiece cutting.

[0047] The collection box 211 is used to collect sewage and debris falling from the guide hood 21. During subsequent processing, it can be slid out of the moving tank.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
