Description

Technical Field

[0001] The present invention relates to the technical field of spraying processing equipment, and particularly relates to a color ribbon spraying device for an oil cylinder piston rod. Background Art

[0002] An oil cylinder can be used to achieve the steering of industrial vehicles such as forklifts and ensure the wheel alignment. In the prior art, a color ribbon groove is opened on the oil cylinder piston rod and tungsten alloy is sprayed to form a color ribbon. When the color ribbon on the piston rod moves to the sensor position, the system senses and sends a signal to the control system to quickly and accurately make corresponding actions for position control. When processing the color ribbon on the piston rod, the prior art usually uses a supersonic spraying device to spray tungsten alloy into the color ribbon groove. However, because the color ribbon groove is relatively narrow, it is easy to spray inaccurately during spraying, resulting in spraying outside the color ribbon groove, which affects the processing quality and later use of the piston rod. And the spraying method in the prior art is usually to replace the next workpiece after one workpiece is sprayed and taken off, resulting in low processing continuity, long processing interval time and low efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a color ribbon spraying device for an oil cylinder piston rod in view of the deficiencies of the prior art. The device includes a spraying mechanism and a piston rod. A color ribbon groove is opened on the piston rod. A transmission mechanism is arranged on one side of the spraying mechanism. A bearing mechanism is arranged on the transmission mechanism. A rotating component is arranged in the transmission mechanism, and a plurality of telescopic components are arranged in a circumferential array on the top of the rotating component. A lower guide rail and an upper guide rail are arranged in the bearing mechanism. A plurality of sleeve a are slidably arranged in the lower guide rail. A power component and a plurality of sleeve b slidably arranged in the upper guide rail are arranged on the upper guide rail, solving the problems in the prior art that it is easy to spray inaccurately during processing, which affects the processing quality and later use of the piston rod, as well as low processing continuity, long processing interval time and low efficiency.

Specific embodiments

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] Embodiment 1

[0022] As Figures 1 to 5 shown, an oil cylinder piston rod ribbon spraying device includes a spraying mechanism 1 and a piston rod 2. A ribbon groove 21 is formed in the piston rod 2. A transmission mechanism 3 is arranged on one side of the spraying mechanism 1, and a bearing mechanism 4 is arranged on the transmission mechanism 3. The transmission mechanism 3 includes a rotating assembly 31 fixedly arranged on one side of the spraying mechanism 1 and a plurality of telescopic assemblies 32 arranged in a circumferential array on the top of the rotating assembly 31. The bearing mechanism 4 includes a lower guide rail 41 arranged below the rotating assembly 31 and an upper guide rail 42 arranged above the rotating assembly 32. A plurality of sleeves a43 are slidably arranged in the lower guide rail 41, and a power assembly 44 and a plurality of sleeves b45 slidably arranged in the upper guide rail 42 are arranged on the upper guide rail 42. The sleeves a43 and the sleeves b45 clamp the piston rod 2 placed in the sleeves a43 during the circumferential movement driven by the rotating assembly 31. The power assembly 44 drives the sleeves a43 and the sleeves b45 to rotate. The spraying mechanism 1 sprays the ribbon groove 21 on the piston rod 2 clamped by the sleeves a43 and the sleeves b45. It solves the problems in the prior art that it is easy to spray incompletely during processing, which affects the processing quality and subsequent use of the piston rod, and the processing continuity is not high, and the processing interval time is long and the efficiency is low.

[0023] As Figure 2As shown in the figure, the rotating assembly 31 includes a base 310, a servo motor a 311 fixedly arranged inside the base 310, and a rotating disk 312 driven by the servo motor a 311. A plurality of through holes 313 are circumferentially formed on the rotating disk 312. The servo motor a 311 drives the rotating disk 312 to rotate intermittently, each time rotating 90°. A plurality of sleeves a 43 with the piston rod 2 placed therein can be automatically transferred to the processing station for spraying processing under the drive of the rotating disk 312. Workers do not need to wait for the previous workpiece to be sprayed and removed before replacing it with the next workpiece for processing. It can ensure that multiple workpieces are pre-loaded, shortening the processing interval time, making the processing more continuous, and improving the processing efficiency. The sizes of the plurality of through holes 313 circumferentially formed on the rotating disk 312 match the sleeves a 43. The sleeves a 43 can be placed in the through holes 313 and follow the rotating disk 312 to perform circular motion when the rotating disk 312 rotates, and then cooperate with the lower guide rail 41 to realize lifting and lowering.

[0024] As Figure 2 shown in the figure, the telescopic assembly 32 includes a telescopic sleeve 320 fixedly arranged on the top of the rotating disk 312 and a telescopic rod 321 slidably arranged inside the telescopic sleeve 320. A collar 322 is fixedly connected to the top of the telescopic rod 321. The telescopic rod 321 cooperates with the limiting ring 453 on the sleeve b 45 through the collar 322 at the top so that the collar 322 is sleeved on the sleeve b 45. When the rotating disk 312 rotates, the telescopic rod 321 can drive the sleeve b 45 to move synchronously, so that the sleeve b 45 can cooperate with the upper guide rail 42 to realize lifting and lowering during circular motion. The telescopic rod 321 is telescopically arranged in the telescopic sleeve 320 and can cooperate with the sleeve b 45 to lift and lower, avoiding interference.

[0025] As Figure 3As shown in the figure, an ascending section a410, a parallel section a411, and a descending section a412 are provided on the lower guide rail 41, and brackets a413 are fixedly connected to both sides of the lower guide rail 41. When the rotating disk 312 drives the sleeve a43 into the ascending section a410, the sleeve a43 gradually rises under the action of the ascending section a410, pushing up the piston rod 2 placed inside the sleeve a43. When the rotating disk 312 drives the sleeve a43 into the parallel section a411, the sleeve a43 rises in place. At this time, the sleeve b45 completes its descent under the action of the upper guide rail 42, cooperating with the sleeve a43 to clamp and fix the piston rod 2 from both the upper and lower directions. When the rotating disk 312 drives the sleeve a43, the sleeve b45, and the clamped piston rod 2 to the position of the spraying mechanism 1, the spraying mechanism 1 processes the piston rod 2. At this time, the sleeve a43 is located within the parallel section a411, and the sleeve b45 is located within the parallel section b421, which can ensure that the piston rod 2 is continuously clamped and fixed during processing. When the rotating disk 312 drives the sleeve a43 into the descending section a412, the sleeve a43 gradually descends and resets under the action of the descending section a412, facilitating the staff to remove the processed piston rod 2.

[0026] As Figure 3 shown in the figure, an ascending section b420, a parallel section b421, and a descending section b422 are provided on the upper guide rail 42, and brackets b423 are fixedly connected to both sides of the upper guide rail 42. When the rotating disk 312 drives the sleeve b45 into the descending section b422, the sleeve b45 gradually descends under the action of the descending section b422, and the servo motor b442 drives the sleeve b45 to continuously rotate by itself through the belt 443. When the rotating disk 312 drives the sleeve b45 into the parallel section b421, the sleeve b45 descends in place. At this time, the sleeve a43 completes its ascent under the action of the lower guide rail 41, cooperating with the sleeve b45 to clamp and fix the piston rod 2 from both the upper and lower directions. When the rotating disk 312 drives the sleeve a43, the sleeve b45, and the clamped piston rod 2 to the position of the spraying mechanism 1, the spraying mechanism 1 processes the piston rod 2. At this time, the sleeve a43 is located within the parallel section a411, and the sleeve b45 is located within the parallel section b421, which can ensure that the piston rod 2 is continuously clamped and fixed during processing. When the rotating disk 312 drives the sleeve b45 into the ascending section b420, the sleeve b45 gradually rises and resets under the action of the ascending section b420, releasing the clamping on the piston rod 2, facilitating the staff to remove the processed piston rod 2.

[0027] As Figure 3As shown, a sliding rod a430 is fixedly arranged at the tail end of the sleeve a43, and a convex ball a431 is fixedly arranged at the tail end of the sliding rod a430. The sleeve a43 and the sleeve b45 make a circular motion driven by the rotating assembly 31. Under the action of the lower guide rail 41 and the upper guide rail 42, the sleeve a43 and the sleeve b45 rise and fall respectively when moving, clamping and fixing the piston rod 2 placed in the sleeve a43 from the upper and lower directions, making the piston rod 2 more stable during processing and avoiding deviation. Moreover, the gap left between the sleeve a43 and the sleeve b45 after clamping the piston rod 2 exactly coincides with the ribbon groove 21 opened on the piston rod 2, making the spraying by the spraying mechanism 1 more in place and uniform when spraying into the ribbon groove 21, not polluting the periphery of the ribbon groove 21, improving the processing quality, and ensuring the good operation of the piston rod 2 during later use; the convex ball a431 is embedded in the lower guide rail 41, so that the sleeve a43 will not fall off when moving along the lower guide rail 41 and moves more smoothly.

[0028] As Figure 4 shown, a sliding rod b450 is fixedly arranged at the tail end of the sleeve b45, a convex ball b451 is fixedly arranged at the tail end of the sliding rod b450, a limiting ring 453 is fixedly arranged on the sleeve b45, and a fixing ring 454 is fixedly arranged on the sliding rod b450. The sleeve a43 and the sleeve b45 make a circular motion driven by the rotating assembly 31. Under the action of the lower guide rail 41 and the upper guide rail 42, the sleeve a43 and the sleeve b45 rise and fall respectively when moving, clamping and fixing the piston rod 2 placed in the sleeve a43 from the upper and lower directions, making the piston rod 2 more stable during processing and avoiding deviation. Moreover, the gap left between the sleeve a43 and the sleeve b45 after clamping the piston rod 2 exactly coincides with the ribbon groove 21 opened on the piston rod 2, making the spraying by the spraying mechanism 1 more in place and uniform when spraying into the ribbon groove 21, not polluting the periphery of the ribbon groove 21, improving the processing quality, and ensuring the good operation of the piston rod 2 during later use; the convex ball b451 is embedded in the upper guide rail 42, playing a supporting role for the sleeve b45 and making the sleeve b45 move more smoothly.

[0029] As Figure 3 and Figure 4As shown in the figure, the power assembly 44 includes a connecting rod 440 fixedly arranged on the top of the bracket 423 and a mounting plate 441 fixedly connected to the front end of the connecting rod 440. A servo motor b442 is fixedly connected to the mounting plate 441, and a plurality of belts 443 are connected to the servo motor b442. When the rotating disk 312 drives the sleeve a43 and the sleeve b45 to perform circular motion, the power assembly 44 can drive the sleeve b45 to achieve continuous self-rotation, so that when the piston rod 2 is transferred to the processing station, the spraying mechanism 1 can evenly spray the ribbon groove 21. A plurality of belts 443 are correspondingly connected to the sleeve b45 on the servo motor b442 in the power assembly 44. The other ends of the belts 443 are sleeved in the fixing rings 454 arranged on the sleeve b45 and connected to the sleeve b45. The sleeve b45 is driven to rotate by the belts 443, and multiple sleeves b45 can be driven to rotate by one power, effectively saving the energy cost.

[0030] As Figure 5 shown in the figure, the spraying mechanism 1 includes a support base 11, and a spray gun 12 is arranged on the support base 11. The spray gun 12 is externally connected with equipment such as a control cabinet, a powder feeder, and a chiller. The ribbon groove 21 on the piston rod 2 transferred to the position of the spraying mechanism 1 is sprayed with tungsten alloy to form a ribbon by the spray gun 12.

[0031] Embodiment 2

[0032] As Figure 3 and Figure 4 shown in the figure, the same or corresponding components as those in Embodiment 1 are marked with the corresponding reference numerals in the drawings of Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below; the difference between this Embodiment 2 and Embodiment 1 is that a baffle a432 is fixedly arranged at the front end of the sleeve a43.

[0033] A baffle b452 is fixedly arranged at the front end of the sleeve b45. After the sleeve a43 and the sleeve b45 clamp the piston rod 2, the gap left between the baffle a432 and the baffle b452 matches the size of the ribbon groove 21, which can further reduce the splashing of tungsten alloy during spraying.

[0034] The working process is as follows.

[0035] During processing, the piston rod 2 to be processed is placed in the sleeve a43. The servo motor a311 drives the rotating disk 312 to rotate intermittently. When the rotating disk 312 drives the sleeve a43 into the rising section a410, the sleeve a43 gradually rises under the action of the rising section a410, lifting the piston rod 2 placed in the sleeve a43. At the same time, when the rotating disk 312 drives the sleeve b45 into the descending section b422, the sleeve b45 gradually descends under the action of the descending section b422. When the rotating disk 312 rotates again and drives the sleeve a43 into the parallel section a411, the sleeve a43 rises in place. At this time, the sleeve b45 completes its descent under the action of the parallel section b421, clamping and fixing the piston rod 2 from both the top and bottom directions. The servo motor b442 drives the sleeve b45 to rotate continuously through the belt 443. When the rotating disk 312 drives the sleeve a43, the sleeve b45, and the clamped piston rod 2 to the position of the spraying mechanism 1, the spraying mechanism 1 processes the piston rod 2. At this time, the sleeve a43 is located in the parallel section a411, and the sleeve b45 is located in the parallel section b421. When the rotating disk 312 rotates again and drives the sleeve a43 into the descending section a412, the sleeve a43 gradually descends and resets under the action of the descending section a412. At the same time, the rotating disk 312 drives the sleeve b45 into the rising section b420, and the sleeve b45 gradually rises and resets under the action of the rising section b420, releasing the clamping of the piston rod 2. Then the worker can remove the processed piston rod 2, and the subsequent processing process circulates in turn.
