Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing and processing technology, specifically a cutting device used in motor manufacturing. Background Technology

[0002] Generators are composed of various parts. Some large generators use larger parts. During the production process, the parts need to go through processing steps such as cutting, grinding, grooving, drilling and welding. Each step requires the use of corresponding equipment.

[0003] However, the rollers on the roller brackets in existing cutting devices are all spaced at a fixed interval. The pipe sizes used in large generators are different, and the pipe sizes of different generator models are also relatively different. As a result, the roller brackets with a single interval cannot provide better support for pipe cutting.

[0004] As disclosed in Chinese Patent CN218341115U, a cutting device for producing generators uses a traction block that is threadedly connected to a lifting screw and slides through a sliding rod. This allows the lifting screw to rotate and drive a double-ring movable shaft to achieve a lifting effect. After the double-ring movable shaft is raised and lowered, it can pull a single-ring movable shaft to slide in a moving groove through the connection of double sleeve arms. This allows the main support with rollers to slide in the groove and change the distance between the rollers. The adjusted spacing can provide support for cutting generator pipes of different sizes. The movable plate, through the rotation of the L-shaped support plate, drives the roller-containing auxiliary support to contact the left and right side walls of the pipe being cut. After the extrusion screw rotates, it presses against the side wall of the movable plate, so that the two roller-containing auxiliary supports or one of them can fit tightly against the two sides of the pipe. When the pipe is cut, it can provide stability for the pipe sitting on the roller-containing main support.

[0005] However, in the existing technology, during the motor production process, it is necessary to cut tubular parts or motor housings, which are relatively cylindrical in appearance and have relatively uneven and smooth outer surfaces. In the process of cutting, the existing clamping structure is prone to the housing rotating due to the high-speed rotation of the cutting components, which affects the cutting accuracy and cutting effect.

[0006] Therefore, we urgently need to provide a cutting device for motor production. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model provides a technical solution: Example 1

[0028] A cutting device for motor production includes a support leg 1, a clamping structure mounted on the top of the support leg 1, a cutting structure on the left side of the clamping structure, and an adsorption and collection structure at the bottom of the clamping structure.

[0029] The clamping structure includes an adjustment unit and a clamping unit. The clamping unit includes a mounting plate 104. Two mounting plates 104 are close to each other, and an abutment block 105 is installed in the middle of one side. An adjustment block 106 is installed in the middle of the mounting plate 104. A transmission component 107 is connected inside the adjustment block 106. A clamping block 108 is connected to the end of the adjustment block 106 away from the mounting plate 104. The adjustment unit includes a worktable 101. A fixing plate 102 is installed in the middle of the front and back of the worktable 101. An electric push rod 103 is installed in the middle of the fixing plate 102.

[0030] The bottom surface of the workbench 101 is fixedly connected to the top of the support leg 1. The two mounting plates 104 are located on opposite sides and connected to the output end of the electric push rod 103. The adjusting block 106 is installed in the middle of the mounting plate 104, and the top and bottom of the mounting plate 104 have convex sliding grooves. The outer surfaces of the abutment block 105 and the clamping block 108 have anti-slip grooves.

[0031] By using the clamping structure, the rotary transmission component 107 drives the adjusting block 106 to move closer to each other, thereby driving the two clamping blocks 108 on the same side to move closer to each other. At the same time, the two electric push rods 103 are activated to drive the two mounting plates 104 to move closer to each other. The workpiece is clamped and fixed by the abutment block 105 and the clamping block 108. The anti-slip grooves on the outer surfaces of the abutment block 105 and the clamping block 108 prevent the workpiece from shifting during the cutting process.

[0032] When clamping and fixing the workpiece, the electric push rod 103 is activated to drive the two mounting plates 104 and the abutment block 105 to move closer to each other, thus initially clamping and fixing the workpiece. Then, the transmission component 107 is rotated, and the two-way threaded rod is threadedly connected to the adjusting block 106, so that the two adjusting blocks 106 drive the clamping block 108 to further clamp and fix the outer surface of the workpiece. During the clamping and fixing process, the anti-slip grooves on the outer surface of the abutment block 105 and the clamping block 108 can effectively prevent the workpiece from shifting due to the cutting rotation force during the cutting process, thus effectively ensuring the cutting accuracy. Example 2

[0033] Based on Embodiment 1, the cutting structure includes a cutting frame 201. A guide rail 202 is installed in the middle of the top and bottom surfaces of the cutting frame 201. A limiting block 203 is connected to the middle of the bottom surface of the guide rail 202. A hydraulic cylinder 204 is installed at the bottom end of the limiting block 203. The output end of the hydraulic cylinder 204 is connected to a cutting assembly 205. A hydraulic cylinder 206 is installed near the top of the front surface of the cutting frame 201. The bottom end of the cutting frame 201 is fixedly connected to the top surface of the worktable 101. The output end of the hydraulic cylinder 206 is connected to the middle of the front surface of the hydraulic cylinder 204. The outer surface of the limiting block 203 is slidably connected to the inner wall of a groove formed in the middle of the bottom surface of the guide rail 202.

[0034] The adsorption and collection structure includes a collection box 301, a collection drawer 302 installed at the bottom of the collection box 301, a filter plate 303 installed on the right side of the collection box 301, and an air pump 304 installed near the bottom of the right side of the collection box 301. The top surface of the collection box 301 abuts against the middle of the bottom surface of the workbench 101 near the left end. The collection drawer 302 is installed and slidably connected to the inner wall of a rectangular hole on the bottom front of the collection box 301 near the left side. The outer surface of the filter plate 303 is slidably connected to the inner wall of a rectangular through hole on the middle front of the collection box 301 near the right end.

[0035] By setting up the cutting structure and the adsorption collection structure, the cutting component 205 can be driven by the hydraulic cylinder 204 to cut the workpiece, and the cutting position can be adjusted by the limit block 203 sliding inside the guide rail 202, thereby improving the cutting effect. The air pump 304 is used to pump air into the collection box 301, and the negative pressure inside the collection box 301 can be used to adsorb and collect the debris generated by cutting through several through holes opened on the top surface of the worktable 101.

[0036] After the workpiece is clamped and fixed, hydraulic cylinder 204 is activated to drive the cutting assembly 205 to descend and cut. At the same time, hydraulic cylinder 206 pushes hydraulic cylinder 204. By using the sliding of the limiting block 203 inside the groove opened in the middle of the bottom surface of the guide rail 202, the cutting position can be effectively adjusted, thereby better completing the cutting work. During the cutting process, the air pump 304 is activated to pump air into the collection box 301. Through several through holes at the bottom of the rectangular groove opened in the middle of the top surface of the worktable 101 near the left end, the cutting debris can be adsorbed and collected. After the debris enters the collection box 301, the filter plate 303 blocks the debris, allowing the debris to enter the collection drawer 302 for centralized processing after collection.
