Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically to a production device for spraying anti-corrosion coating on the surface of a slewing bearing. Background Technology

[0002] Slewing bearings are core transmission components widely used in engineering machinery, wind power generation, and other fields. Their harsh working environment necessitates surface anti-corrosion coating treatment to extend their service life. Automated spraying is the primary production method for achieving efficient and uniform coating coverage.

[0003] In the spraying process, the coating quality is directly related to the cleanliness of the workpiece surface. During the processing and transportation of slewing bearings, dust, metal shavings, and other impurities inevitably adhere to their surfaces. If these impurities are not effectively removed before spraying, the adhesion of the coating will be severely affected, leading to problems such as peeling and flaking of the coating later on, and shortening the effective period of corrosion protection.

[0004] To ensure coating quality, existing production processes typically include a separate cleaning station before the spraying step, such as manual blowing or wiping, before transferring the workpiece to the spraying equipment. Similarly, after spraying, the wet coating needs time to cure; natural air drying is inefficient. Adding separate drying or air-drying equipment further increases the complexity of the process and the space required. This production model, which separates cleaning, spraying, and drying processes, results in a disjointed production flow, low automation, and not only extends the overall production cycle but also increases the labor intensity of manual handling and the potential risk of secondary contamination. Existing spraying equipment is often single-function, only capable of spraying, lacking the ability to integrate pre-spray dust removal and post-spray auxiliary drying at the same station, making it difficult to meet the demands of modern production for high-efficiency, highly integrated equipment.

[0005] Therefore, this utility model proposes a production device for spraying anti-corrosion coating on the surface of slewing bearings to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a slewing bearing surface anti-corrosion coating spraying production device, which aims to improve the existing technology's single function, inability to integrate pre-spraying dust removal and cleaning and post-spraying air drying functions at the same workstation, resulting in low automation and discontinuous production process.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a slewing bearing surface anti-corrosion coating spraying production device, comprising a support frame, a moving mechanism, the moving mechanism being disposed above the support frame, the moving mechanism including an X-axis assembly and a Y-axis assembly; the X-axis assembly including a reciprocating lead screw, a sliding rod parallel to the reciprocating lead screw, and a motor; a moving column, the moving column being threadedly engaged with the reciprocating lead screw and slidably sleeved on the sliding rod, the motor driving the reciprocating lead screw to rotate to drive the moving column to move along the X-axis; the Y-axis assembly including a slide rail and a sliding block, the slide rail being fixed to the moving column, the sliding block being slidably connected to the slide rail; a mounting box, the mounting box being fixedly connected to the sliding block; a spray head, the spray head being disposed below the mounting box; and an air blowing mechanism;

[0008] The structure of the blowing mechanism is that it includes a motor, a cam, a transmission rod, a push rod, a piston, and an air blowing cylinder mounted on the moving column.

[0009] Furthermore, the power component, transmission component, and execution component of the air blowing mechanism are combined through a complete power transmission relationship. The output end of the second motor is connected to one end of the transmission rod, and the other end of the transmission rod is connected to the cam. The cam abuts against one end of the push rod. The other end of the push rod is fixedly connected to the piston, and the piston is slidably disposed inside the air blowing cylinder. One end of the air blowing cylinder is connected to an air outlet pipe. As the key to this combination relationship, the power generation part of the air blowing mechanism moves along the X-axis with the moving column, while the airflow output part of the air blowing mechanism, i.e., the other end of the air outlet pipe, is connected to the mounting box that moves along the Y-axis with the sliding block.

[0010] Preferably, a spring is sleeved on the outer periphery of the push rod, and the two ends of the spring abut against the wall of the air blower and the push plate on one end of the spring, respectively.

[0011] Preferably, the air blowing cylinder has an air intake hole on its cylinder wall;

[0012] Preferably, the other end of the air outlet pipe is fixedly connected to the mounting box by a retaining ring;

[0013] Preferably, shock-absorbing blocks are fixedly connected to both ends of the slide rail;

[0014] Preferably, the nozzle is fixedly connected to the lower surface of the adjusting ball;

[0015] Preferably, an adjusting rod is fixedly connected to the bottom of the mounting box, and the other end of the adjusting rod is slidably connected to a groove on the upper surface of the adjusting ball;

[0016] Preferably, the outer peripheral surface of the cam is an uneven surface, and when the cam rotates, it pushes the push rod to reciprocate through the uneven surface.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problems of inconvenient dust cleaning on the surface of the slewing bearing before spraying and slow coating drying after spraying by linking the air blowing mechanism with the moving mechanism, so that the air outlet of the air blowing mechanism can move synchronously with the nozzle. It achieves the effects of automatic dust removal before spraying and auxiliary air drying after spraying, improves the bonding strength between the coating and the workpiece, and shortens the production cycle.

[0019] 2. This utility model solves the problem of traditional spraying devices having a fixed nozzle angle, making it difficult to effectively spray the side wall of the slewing bearing. It achieves the ability to easily adjust the nozzle spray angle, realize multi-angle and all-round spraying of the workpiece, and enhance the applicability of the device and the integrity of the spray coverage.

[0020] 3. This utility model integrates the main body of the air blowing mechanism and the spraying components on the same XY moving mechanism, and makes the air blowing port and the spray head move synchronously. This solves the problem that multiple equipment or complex structures are required to realize multiple processes of cleaning, spraying and drying in the prior art. It achieves the effects of compact structure, multi-purpose machine and high degree of automation, and reduces the equipment footprint and production cost. Attached Figure Description

[0028] 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.

[0029] Reference Figures 1-5 This utility model provides an embodiment of a slewing bearing surface anti-corrosion coating spraying production device, including a support frame 1 and a moving mechanism 2 disposed above the support frame 1. The moving mechanism 2 includes an X-axis assembly and a Y-axis assembly. The X-axis assembly includes a reciprocating screw 201, a sliding rod 202 parallel to the reciprocating screw 201, and a motor 207. A moving column 203 is threadedly engaged with the reciprocating screw 201 and slidably sleeved on the sliding rod 202. The motor 207 drives the reciprocating screw 201 to rotate so as to drive the moving column 203 to move along the X-axis. The Y-axis assembly includes a slide rail 204 and a sliding block 205. The slide rail 204 is fixed to the moving column 203, and the sliding block 205 is slidably connected to the slide rail 204. Anti-vibration blocks 206 are fixedly connected to both ends of the slide rail 204. A mounting box 208 is fixedly connected to the sliding block 205, and a spray head 211 is disposed below the mounting box 208.

[0030] It also includes an air blowing mechanism 3, which includes a motor 307 mounted on the moving column 203, a cam 305, a transmission rod 310, a push rod 309, a piston 304, and an air blowing cylinder 301. The output end of the motor 307 is connected to one end of the transmission rod 310, and the other end of the transmission rod 310 is connected to the cam 305. The outer peripheral surface of the cam 305 is uneven. The cam 305 abuts against one end of the push rod 309. When the cam 305 rotates, it pushes the push rod 309 to reciprocate through the uneven surface. The other end of the push rod 309 is fixedly connected to the piston 304. The piston 304 is slidably disposed inside the air blowing cylinder 301. A spring 306 is fitted around the outer periphery of the 9. The two ends of the spring 306 abut against the wall of the air blower 301 and the push plate on one end of the push rod 309, respectively. An air intake hole 302 is opened on the wall of the air blower 301. One end of the air blower 301 is connected to an air outlet pipe 303. The other end of the air outlet pipe 303 is connected to the mounting box 208. The other end of the air outlet pipe 303 is fixedly connected to the mounting box 208 through a fixing ring 308. The nozzle 211 is fixedly connected to the lower surface of the adjusting ball 210. An adjusting rod 209 is fixedly connected to the bottom of the mounting box 208. The other end of the adjusting rod 209 is slidably connected to the groove on the upper surface of the adjusting ball 210.

[0031] The air blowing mechanism 3 includes a motor 307, a cam 305, a transmission rod 310, a push rod 309, a piston 304, and an air blowing cylinder 301, all mounted on the movable column 203. The output end of the motor 307 is connected to one end of the transmission rod 310, and the other end of the transmission rod 310 is connected to the cam 305 to drive the cam 305 to rotate. The outer peripheral surface of the cam 305 is uneven. When the cam 305 rotates, it pushes the push rod 309 to reciprocate through the uneven surface. The cam 305 abuts against one end of the push rod 309, and the other end of the push rod 309 is fixedly connected to the piston 304. The piston 304 is slidably disposed inside the air blowing cylinder 301. A spring 306 is sleeved on the outer periphery of the push rod 309. The two ends of 6 abut against the wall of the air blower 301 and the push plate at one end of the push rod 309, respectively, to drive the piston 304 to reset after the uneven surface of the cam 305 rotates away. The air blower 301 has an air intake hole 302 on its cylinder wall, which is used to draw in external air when the piston 304 resets. One end of the air blower 301 is connected to an air outlet pipe 303, and the other end of the air outlet pipe 303 is fixedly connected to the mounting box 208 through a fixing ring 308. This installation structure, in which the main body of the air blowing mechanism is separated from the end of the air outlet pipe, ensures that the air outlet of the air outlet pipe 303 can move synchronously with the mounting box 208 and the nozzle 211 in the X and Y axes, thereby performing precise air blowing operations on the spraying area.

[0032] To provide air to the air pump 301, an air intake hole 302 is provided on the cylinder wall of the air pump 301. The other end of the air outlet pipe 303 is fixedly connected to the mounting box 208 through a fixing ring 308. In order to reduce the impact when the sliding block 205 moves to the end of its stroke and to protect the structure of the device, shock absorbers 206 are fixedly connected to both ends of the slide rail 204. The nozzle 211 is fixedly connected to the lower surface of the adjusting ball 210. An adjusting rod 209 is fixedly connected to the bottom of the mounting box 208. The other end of the adjusting rod 209 is slidably connected to the groove on the upper surface of the adjusting ball 210. The angle of the adjusting ball 210 can be changed by manually operating the adjusting rod 209. In order to effectively convert the rotational motion of the motor 307 into the linear reciprocating motion of the push rod 309, the outer peripheral surface of the cam 305 is an uneven surface. When the cam 305 rotates, it can periodically push the push rod 309 to reciprocate through the uneven surface.

[0033] Working principle: When performing the operation, the slewing bearing is first placed on the support frame 1. The moving mechanism 2 and the air blowing mechanism 3 are started to clean the surface before spraying. The motor 207 is started, and the motor 207 drives the reciprocating screw 201 to rotate. Since the moving column 203 is threadedly engaged with the reciprocating screw 201, the moving column 203 will move back and forth along the X-axis under the guidance of the sliding rod 202. At the same time, the Y-axis drive source drives the sliding block 205 to move along the slide rail 204 fixed on the moving column 203 in the Y-axis direction. The anti-vibration blocks 206 at both ends of the sliding block 205 play a buffering role. Through the combined movement of the X-axis and Y-axis, the mounting box 208 fixed on the sliding block 205 is driven to move in the plane above the slewing bearing.

[0034] While the mounting box 208 is moving in a plane, the air blowing mechanism 3 mounted on the moving column 203 starts to work. The motor 307 drives the cam 305 to rotate through the transmission rod 310. The uneven surface of the outer periphery of the cam 305 will periodically push the push rod 309. The push rod 309 drives the piston 304 to compress air in the air blowing cylinder 301. The gas is blown out through the air outlet pipe 303. When the uneven surface of the cam 305 rotates away from the push rod 309, the spring 306 pushes the piston 304 to reset and draws in air through the air intake hole 302, completing one air blowing cycle. Since the end of the air outlet pipe 303 is fixed to the mounting box 208 by the fixing ring 308, the blown airflow will follow the movement trajectory of the mounting box 208 and perform comprehensive dust removal on the surface of the slewing bearing.

[0035] After surface cleaning is completed, stop the air blowing mechanism 3 and start the spraying system. The paint is sprayed out through the nozzle 211. Using the planar movement capability of the moving mechanism 2, the nozzle 211 is controlled to spray a uniform anti-corrosion coating on the surface of the slewing bearing. When it is necessary to spray the side of the slewing bearing, the adjusting rod 209 connected to the bottom of the mounting box 208 can be manually operated. The adjusting rod 209 slides in the groove on the upper surface of the adjusting ball 210, thereby changing the tilt angle of the adjusting ball 210 and driving the nozzle 211 fixed on the lower surface of the adjusting ball 210 to adjust the spraying direction to meet the needs of side spraying. After the spraying operation is completed, the air blowing mechanism 3 can be restarted to use the synchronously moving airflow to dry the wet coating surface.
