Description

Technical Field

[0001] The invention relates to the technical field of piston rod cleaning, and in particular to a piston rod cleaning device and process. Background Art

[0002] The piston rod is a connecting component that supports the piston to do work. Most of them are used in oil cylinders and cylinder motion actuators. During the piston rod processing process, the finely processed piston rods are placed together in an orderly manner. There are lathe lubricants, metal chips and other substances on the surface. Before electroplating, these substances need to be removed to ensure that the surface of the piston rod is thoroughly cleaned before electroplating. In the prior art, there are two ways to clean the piston rod: spraying and soaking. The cleaning liquid sprayed by the spray device can rinse the surface of the piston rod. However, the contact time between the cleaning liquid and the surface of the piston rod is short, which is not conducive to the full reaction of the cleaning liquid and the oil stains. Soaking can increase the time for the cleaning liquid to fully react with the oil stains, but lacks the effect of flushing, which is not conducive to removing the metal chips that adhere to the surface of the piston rod and do not react with the cleaning liquid. After the piston rod is cleaned, it is usually necessary to transfer the piston rod to a drying station to dry the piston rod to keep the surface of the piston rod clean.

[0003] The patent application document with the publication number CN114589150A discloses a cylinder piston rod cleaning device, including a cleaning rack, a cleaning liquid tank provided on the cleaning rack, a rotating shaft rotatably connected to the cleaning rack, a plurality of swing arms connected to the rotating shaft, and a driving device for driving the rotating shaft to rotate provided on the cleaning rack; one end of the swing arm is a connecting end connected to the rotating shaft, and the other end is a swing end, and an upwardly curved blocking portion is provided on the swing end; a placing rack assembly for placing the piston rod is provided on one side of the cleaning rack; and a rotating supporting mechanism for supporting and driving the piston rod to rotate is provided in the cleaning liquid tank. When the cleaning device cleans the piston rod, the entire piston rod is immersed in the cleaning liquid, and during the cleaning process, the piston rod can rotate in the cleaning liquid, but the piston rod cannot be rinsed, and the piston rod cannot be dried at the same time after cleaning. Summary of the invention

[0004] In view of this, the present invention provides a piston rod cleaning device and process, aiming to solve the technical problem in the prior art that the piston rod cannot be rinsed and soaked at the same time and dried at the same time after cleaning.

[0005] In order to solve the above technical problems, on the one hand, the present invention provides a piston rod cleaning device, comprising a body, a conveying mechanism and a cleaning mechanism arranged on the body, wherein the conveying mechanism comprises a moving seat, a linear driver 1 driving the moving seat to rise and fall, a gear transmission unit driving the moving seat to move horizontally, a moving plate slidably connected in the moving seat, a linear driver 2 driving the moving plate to rise and fall, and a stopper fixedly arranged at the bottom of the moving plate;

[0006] The cleaning mechanism comprises a cleaning tank arranged in the body and located below the moving seat, a clamping plate rotatably connected to the lower part of the moving seat, an arc-shaped supporting plate fixedly arranged in the clamping plate and capable of supporting the piston rod, a rotating roller rotatably connected to the moving plate and capable of driving the piston rod to rotate, and a spray pipe fixedly connected to the moving plate and located on one side of the rotating roller;

[0007] The upper parts of the two clamping plates are connected with elastic parts, and the lifting and lowering of the stopper can drive the two clamping plates to open or close. The other side of the rotating roller on the movable plate is fixedly connected with a high-pressure airflow nozzle.

[0008] By adopting the above technical solution, the linear driver 1 and the gear transmission unit drive the moving seat to move. At this time, the upper end of the clamping plate is closed and the lower end is opened under the action of the elastic member. When the moving seat moves to the arc-shaped support plate to contact the piston rod, the linear driver 2 drives the moving plate to move downward, and the moving plate drives the block to move downward. The block pushes the clamping plate, the upper end of the clamping plate is opened, and the lower end is tightened. The arc-shaped support plate holds up the piston rod. The linear driver 1 and the gear transmission unit drive the moving seat to move, so that the piston rod is located in the cleaning tank, the spray pipe sprays the cleaning liquid, the rotating roller drives the piston rod to rotate, and the cleaning liquid can fully rinse the piston rod. The sprayed cleaning liquid falls into the cleaning tank to soak the piston rod. The present invention can not only fully rinse the piston rod, but also remove impurities such as metal chips that do not react with the cleaning liquid attached to the surface of the piston rod, and can also soak the piston rod, which can prolong the contact time between the cleaning liquid and the piston rod, so that the cleaning liquid and the oil on the surface of the piston rod can fully react, and improve the cleaning effect. At the same time, the cleaning tank can collect the cleaning liquid, which is convenient for the recovery and utilization of the cleaning liquid. After the piston rod is cleaned, the linear actuator drives the moving seat to move upward, the piston rod moves upward, and the high-pressure airflow nozzle sprays high-pressure airflow to dry the piston rod. The piston rod of the present invention can be dried at the same time after cleaning, which reduces the steps of transferring the piston rod, improves the cleaning efficiency, and also reduces the impact on the cleanliness of the piston rod caused by dust impurities in the air falling on the wet piston rod during the transfer process.

[0009] Preferably, the linear drive 1 is provided on both sides of the cleaning tank, a support plate is slidably connected to the body, a driving shaft of the linear drive 1 is fixedly connected to the support plate, and the gear transmission unit includes a rack fixedly connected to one side of the support plate, a motor 1 fixedly connected to the moving seat, and a gear fixedly arranged on the rotating shaft of the motor 1 and meshing with the rack.

[0010] By adopting the above technical solution, the linear drive drives the support plate to rise and fall, and the support plate drives the moving seat to rise and fall, thereby realizing the lifting and lowering of the clamping plate and the arc-shaped support plate, and the piston rod can be lifted or placed; the motor drives the gear to rotate along the rack, driving the moving seat to move horizontally, thereby facilitating the horizontal movement of the piston rod.

[0011] Preferably, the second linear actuator is fixedly arranged at the lower part of the movable seat, the driving shaft of the second linear actuator is fixedly connected to the movable plate, and the width of the stopper decreases from top to bottom.

[0012] By adopting the above technical solution, linear drive 2 drives the moving plate to rise and fall, and the moving plate drives the block to rise and fall. When the block descends, the block can push the upper end of the splint to open and the lower end to close, so that the arc-shaped support plate can support the piston rod; when the block rises, under the action of the elastic part, the upper end of the splint is slowly tightened and the lower end is opened, and the piston rod can fall from the arc-shaped support plate.

[0013] Preferably, a groove is provided at the lower portion of the movable seat, a support rod is fixedly connected in the groove, and the clamping plate is rotatably connected to the support rod.

[0014] By adopting the above technical solution, the clamping plate passes through the groove and is rotatably connected to the support rod, which can be deflected, thereby achieving the lifting or loosening of the piston rod by the arc-shaped support plate.

[0015] Preferably, the upper end of the splint is fixedly connected with a connecting rod 1, and the connecting rod 1 is rotatably connected with a roller 1 that can contact the block, the lower end of the splint is fixedly connected with a connecting rod 2, and the connecting rod 2 is rotatably connected with a roller 2 that can contact the piston rod, and the elastic member is fixedly connected to the two connecting rods 1.

[0016] By adopting the above technical solution, roller one rolls on the stopper, and roller two rolls on the piston rod, which reduces the friction between the stopper and the piston rod and helps the rotating roller drive the piston rod to rotate.

[0017] Preferably, a flexible baffle is fixedly connected inside the arc-shaped supporting plate, and bristles are fixedly connected inside the arc-shaped supporting plate below the flexible baffle.

[0018] By adopting the above technical solution, the flexible baffle prevents the arc-shaped support plate from directly contacting the piston rod, which not only increases the protection of the piston rod and facilitates the rotating roller to drive the piston rod to rotate, but also the gap between the piston rod and the arc-shaped support plate is conducive to the passage of the cleaning liquid, thereby enhancing the immersion effect of the piston rod in the cleaning liquid. The bristles can clean the surface of the piston rod when washing and soaking the piston rod.

[0019] Preferably, the end of the rotating roller is fixedly connected to a pulley 1, the upper end of the movable plate is fixedly connected to a motor 2, the rotating shaft of the motor 2 is fixedly connected to a pulley 2, a synchronous belt is connected between the pulley 1 and the pulley 2, and the synchronous belt is also connected between multiple pulleys 1.

[0022] By adopting the above technical solution, the support frame is used to support and place the piston rod. Before cleaning, the arc-shaped support plate lifts the piston rod on the support frame. After cleaning and drying, the arc-shaped support plate places the piston rod on the support frame.

[0023] On the other hand, the present invention provides a piston rod cleaning process, using the piston rod cleaning device, comprising the following steps:

[0024] S1: Start motor 1, the moving seat moves to the top of the support frame, the linear actuator 1 drives the moving seat to move downward, the arc-shaped support plate contacts the piston rod, the linear actuator 2 drives the moving plate to move downward, the stopper moves downward to push the upper end of the clamping plate to open, the arc-shaped support plate holds up the piston rod, and the motor 1 and the linear actuator 1 drive the moving seat to move the piston rod into the cleaning tank;

[0025] S2: The spray pipe sprays cleaning liquid to rinse the piston rod, the motor 2 drives the rotating roller to rotate, the piston rod rotates, the bristles clean the piston rod, and the cleaning liquid falling into the cleaning tank soaks the piston rod. After cleaning, the spray pipe is closed, the linear drive 1 is started, the piston rod moves up, and the high-pressure air flow nozzle dries the piston rod. After drying, the motor 2 is closed;

[0026] S3: Motor 1 and linear drive 1 move the piston rod to the support frame, linear drive 2 drives the moving plate to move up, the block moves up, the arc support plate opens, and the piston rod falls onto the support frame.

[0027] By adopting the above technical solution, the present invention can not only fully flush the piston rod, but also remove impurities such as metal chips that do not react with the cleaning liquid and adhere to the surface of the piston rod, and can also soak the piston rod, which can extend the contact time between the cleaning liquid and the piston rod, so that the cleaning liquid and the oil on the surface of the piston rod can fully react, thereby improving the cleaning effect. After the piston rod is cleaned, the high-pressure airflow nozzle sprays high-pressure airflow to dry the piston rod, which reduces the steps of transferring the piston rod, improves the cleaning efficiency, and also reduces the impact on the cleanliness of the piston rod caused by dust impurities in the air falling on the wet piston rod during the transfer process.

[0028] The beneficial effects of the above technical solution of the present invention are as follows:

[0029] 1. The present invention can not only fully rinse the piston rod, but also remove impurities such as metal chips that adhere to the surface of the piston rod and do not react with the cleaning liquid, and can also soak the piston rod, which can prolong the contact time between the cleaning liquid and the piston rod, so that the cleaning liquid and the oil on the surface of the piston rod can fully react, thereby improving the cleaning effect. At the same time, the cleaning tank can collect the cleaning liquid, which is convenient for the recovery and utilization of the cleaning liquid. After the piston rod is cleaned, the high-pressure airflow nozzle sprays high-pressure airflow to dry the piston rod, which reduces the steps of transferring the piston rod, improves the cleaning efficiency, and also reduces the influence of dust impurities in the air falling onto the wet piston rod during the transfer of the piston rod on the cleanliness of the piston rod.

[0030] 2. A flexible baffle and bristles are provided on the arc-shaped support plate. The flexible baffle prevents the arc-shaped support plate from directly contacting the piston rod, which not only increases the protection of the piston rod and facilitates the rotating roller to drive the piston rod to rotate, but also the gap between the piston rod and the arc-shaped support plate is conducive to the passage of the cleaning liquid, thereby enhancing the immersion effect of the piston rod in the cleaning liquid; the bristles can clean the surface of the piston rod when flushing and soaking the piston rod.

[0031] 3.

In this embodiment, the linear actuator 1 4 and the linear actuator 2 9 are both one of the cylinders or hydraulic cylinders. Slide grooves are provided on both sides of the rack 7, and a slider is slidably connected to the slide groove, and the slider is fixedly connected to the moving seat 2, and the rack 7 passes through the slide groove.

[0046] like Figure 1 , Figure 3 , Figure 4 As shown, the cleaning mechanism includes a cleaning tank 5, a clamping plate 18, an arc-shaped supporting plate 16, a rotating roller 20 and a spray pipe 19. The cleaning tank 5 is arranged in the machine body 1 below the movable seat 2, and collects the cleaning liquid sprayed in the spray pipe 19, so as to facilitate the immersion of the piston rod 17. Both sides of the cleaning tank 5 are provided with a linear drive 4 to realize the lifting and lowering of the movable seat 2.

At the same time, the cleaning tank 5 can collect the cleaning liquid, which is convenient for the recovery and utilization of the cleaning liquid. After the piston rod 17 is cleaned, the linear drive 14 drives the moving seat 2 to move upward, the piston rod 17 moves upward, and the high-pressure airflow nozzle 21 sprays high-pressure airflow to dry the piston rod 17.
