Description

Technical Field

[0001] This utility model belongs to the technical field of horizontal lathes, specifically relating to a lathe spindle maintenance device. Background Technology

[0002] The background technology of lathe spindle maintenance and repair devices mainly focuses on the long-term use, maintenance, and fault prevention of lathe spindles. The lathe spindle is one of the most critical components of a lathe, bearing a heavy workload and requiring long-term operation at high speeds. Therefore, proper maintenance and repair are essential to ensuring the normal operation of the lathe and extending its service life.

[0003] Patent publication number CN213915193U discloses a cleaning device for maintaining the spindle of a horizontal lathe, including a frame and movable wheels. Each of the four corners of the bottom end of the frame is equipped with a movable wheel, and the frame and movable wheels are fixedly connected by bolts. A drain pipe is provided on the right side of the frame, and a control panel is provided on the left side. This patent utilizes a buffer mechanism at each of the left and right ends inside the inner tank. During spindle cleaning, both ends of the spindle are respectively fitted into the buffer mechanisms at both ends. The buffer mechanisms at both ends securely fix the spindle, preventing it from shaking during cleaning. By incorporating buffer components inside the buffer mechanisms, the placed spindle achieves a better cushioning effect, avoiding hard contact between the spindle and the buffer mechanism under the action of water flow. This effectively improves the overall structure's protection of the spindle.

[0004] However, the current cleaning devices for the maintenance of horizontal lathe spindles have the following problems: after long-term operation, the spindle surface deforms and impurities accumulate, which seriously affects subsequent use. Even after the dimensions are corrected, there will still be a large error during grinding and maintenance. Therefore, we propose a lathe spindle maintenance device. Utility Model Content

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1-5 As shown, a lathe spindle maintenance device includes a main body plate 1. A spraying assembly for cooling and cleaning the workpiece is installed on the top of the main body plate 1. A support plate 6 is fixedly connected to the top of the main body plate 1. An extension support frame 7 is fixedly connected to the side of the support plate 6. An electric telescopic caliper 8 is fixedly connected to the side of the extension support frame 7. The electric telescopic caliper 8 has self-adjusting characteristics, which not only protects the workpiece but also effectively improves the fit of the device. A positioning device 9 is installed on the side of the support plate 6. The positioning device 9 includes an adjustment component for adjusting positioning accuracy. Two electric telescopic rulers 96 are fixedly connected to the moving end of the adjustment component. A positioning rod 97 is fixedly connected to the bottom of the two electric telescopic rulers 96. The positioning rod 97 ensures that the fixing parts at both ends are on a uniform movement trajectory. A fixing hole 99 is opened on the side of the fixing plate of the electric telescopic caliper 8, and a fixing pin 910 is inserted into the inner wall of the fixing buckle 98.

[0025] The adjustment component for adjusting positioning accuracy also includes an outer plate 91 fixedly connected to the side of the support plate 6. An adjustment knob 92 is rotatably connected through the side of the outer plate 91. A double-control gear 93 is fixedly connected to the end of the adjustment knob 92 near the support plate 6. A positioning disk 94 is rotatably connected through the side of the support plate 6. Two tension racks 95 are slidably connected to the inner wall of the slot on the side of the positioning disk 94. The two tension racks 95 are the moving ends of the adjustment component. The two tension racks 95 mesh with the double-control gear 93. A fixing buckle 98 is fixedly connected to the side of the tension racks 95. The adjustment knob 92 facilitates the operator to adjust the size.

[0026] The spraying assembly for cooling and cleaning workpieces also includes a water tank 2 fixedly connected to the top of the main plate 1. A pressure pump 3 is fixedly connected to the top of the water tank 2, and a booster box 4 is fixedly connected to the top of the pressure pump 3. A flat spray nozzle 5 is fixedly inserted through the side of the booster box 4. The flat spray nozzle 5 is connected to the inside of the booster box 4. The cooling liquid is delivered to the booster box 4 by the pressure pump 3, and then sprayed onto the workpiece by the flat spray nozzle 5 through the booster box 4, thus ensuring all-round cooling of the workpiece.

[0027] The fixing hole 99 is located on the movement trajectory of the fixing pin 910. The inner diameter of the fixing hole 99 is equal to that of the fixing buckle 98. Because the dimensions of the spindle are extremely precise, it is necessary to ensure that the fastener is very secure.

[0028] Based on the above structure, the electric telescopic caliper 8 is used to fix the spindle workpiece that needs maintenance onto the device. The pressure pump 3 is turned on, so that the flat spray nozzle 5 sprays the coolant in the water tank 2 onto the spindle workpiece that needs maintenance through the booster box 4. The adjustment knob 92 is turned, which drives the double control gear 93 to rotate. The rotation of the double control gear 93 causes the two tension racks 95 to slide towards each other along the two slots of the positioning plate 94. The sliding of the tension racks 95 towards each other causes the electric telescopic ruler 96 to slide towards each other, so that the electric telescopic ruler 96 can be positioned according to the required size of the spindle. When the limited size is reached, the fixing pin 910 is inserted into the fixing buckle 98 and the fixing hole 99, thereby limiting the position of the tension rack 95 to fix the limited size, so as to ensure the grinding accuracy when performing high-precision grinding maintenance on the surface of the spindle maintenance parts.

[0029] like Figure 1-5 As shown, a grinding device 10 is provided on the side of the support plate 6. The grinding device 10 includes a motor bracket 1001, which is fixedly connected to the side of the support plate 6. An output motor 1002 is fixedly connected to the side of the motor bracket 1001 away from the support plate 6. The output shaft of the output motor 1002 is fixedly connected to a drive gear 1003. A rotary disk 1004 is rotatably connected through the side of the support plate 6. A toothed ring 1005 is fixedly connected to the side of the rotary disk 1004. The toothed ring 1005 meshes with the drive gear 1003. Two grinding sliders 1006 are slidably connected in the two slots of the rotary disk 1004. Two grinding columns 1007 are slidably connected through the sides of the two grinding sliders 1006. The grinding columns 1007 follow the movement of the corresponding rod 97 to ensure that the specified dimensions will not deviate from the specified dimensions.

[0030] A gap is provided between the grinding column 1007 and the extension support frame 7, and a gap is provided between the grinding column 1007 and the electric telescopic caliper 8 to ensure the normal operation of the grinding column 1007 during the working process.

[0031] According to the above structure, the two electric telescopic rulers 96 slide towards the center of the positioning disk 94, causing the two corresponding rods 97 to slide towards the center of the positioning disk 94. The sliding of the corresponding rods 97 towards the center of the positioning disk 94 causes the grinding column 1007 to slide towards each other. The sliding of the grinding column 1007 towards each other causes the grinding slider 1006 to slide along the inner wall of the groove on the rotary disk 1004 towards the center of the rotary disk 1004. When the grinding column 1007 reaches the designated position, the output motor 1002 is turned on. The output shaft of the output motor 1002 rotates, causing the drive gear 1003 to rotate. The rotation of the drive gear 1003 causes the following gear ring 1005 to rotate. The rotation of the following gear ring 1005 causes the rotary disk 1004 to rotate. The rotation of the rotary disk 1004 causes the grinding slider 1006 to rotate. The rotation of the grinding slider 1006 causes the grinding column 1007 to rotate, so that the grinding blade of the grinding column 1007 can effectively and accurately grind the protruding deformation positions and impurities on the workpiece being maintained.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
