Description

Technical Field

[0001] This invention relates to the field of hydraulic cylinder housing processing equipment, and in particular to a coating mechanism and method for relieving stress on the side of a hydraulic cylinder housing. Background Technology

[0002] The coating mechanism for relieving stress on the sides of hydraulic cylinder housings is typically constructed using multiple layers of materials. The hydraulic cylinder housing is the base layer, covered by a coating layer. This coating layer has high strength and rigidity, capable of withstanding the stress caused by the working fluid inside the hydraulic cylinder. The coating effectively eliminates the stress on the sides of the hydraulic cylinder housing. A common coating method involves applying adhesive to the housing and then bonding the coating steel plate material to the side surface of the housing, thereby eliminating the stress on the sides of the hydraulic cylinder housing.

[0003] In the prior art, when coating the hydraulic cylinder housing, air bubbles are easily generated in the adhesive layer during the application of adhesive, resulting in poor adhesion strength and stability between the steel plate and the surface of the hydraulic cylinder housing. This reduces the elimination of lateral stress and thus shortens the service life of the hydraulic cylinder. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art that when applying adhesive, air bubbles are easily generated in the adhesive layer, which leads to poor adhesion strength and stability between the steel plate and the surface of the hydraulic cylinder housing, reduces the elimination of lateral stress, and thus reduces the service life of the hydraulic cylinder.

One end of the telescopic rod is fixedly connected to a connecting rod. An air intake is provided at one end of the telescopic rod, and a valve is provided on the air intake. An air supply pipe is installed on the telescopic rod, and the end of the air supply pipe is connected to a connecting box. An L-shaped plate is installed on the inner wall of the connecting box. An impeller is provided inside the connecting box, and a rotating rod is fixed at the axis of the impeller. One end of the rotating rod is rotatably connected to the inner wall of the connecting box through a bearing, and a reciprocating component is provided through the L-shaped plate at one end of the rotating rod.

[0008] Preferably, the reciprocating component includes an eccentric wheel fixed to the end of the rotating rod, a T-shaped rod is attached to the surface of the eccentric wheel, a connecting plate is fixed to the bottom of the T-shaped rod, and a return spring is fixed to the top surface of the T-shaped rod on one side of the eccentric wheel. The end of the return spring is fixedly connected to the inner wall of the connecting box.

[0009] Preferably, the top of the connecting plate is provided with a conveying assembly for intermittently adding defoaming agent to the puncture needle site. The conveying assembly includes a slide rod fixed to the top of the connecting plate, the slide rod being slidably connected inside the connecting cylinder, a piston being slidably connected inside the connecting cylinder, the bottom of the piston being fixedly connected to the slide rod, a drainage tube being fixed to the top of the connecting cylinder, the end of the drainage tube passing through the connecting box and communicating with the liquid outlet, the liquid outlet being installed on the top surface of the connecting box, and a conveying component being provided on one side of the connecting cylinder.

[0010] Preferably, the conveying component includes a liquid storage box disposed on the connecting cylinder, one end of which is fixed with a liquid guide tube, and the end of the liquid guide tube passes through the connecting plate and is connected to the puncture needle.

[0011] Preferably, the interior of the connecting box is formed by an L-shaped plate, an air vent is provided on one side of the connecting box, an air vent pipe is fixed on the bottom surface of the L-shaped plate, the air vent pipe is L-shaped, a heating pipe is provided on the air vent pipe, and an inlet is provided at the top of the liquid outlet.

[0012] Preferably, the bottom surface of the arc-shaped plate is provided with an adsorption plate, the end of the adsorption plate is connected to a vacuum pump through a pipe, the vacuum pump is mounted on the mounting plate, the bottom of the mounting plate is fixedly connected to the arc-shaped plate, and the top of the mounting plate is fixedly connected to the first driving part.

[0013] Preferably, the box body is provided with a clamping cylinder, a limit block is provided on the other end of the box body located on the workpiece, and a collection box is provided on one side of the box body located on the limit block.

[0014] A method for relieving stress on the side of a hydraulic cylinder housing by coating mainly includes the following steps: Step A: During the coating operation, the workpiece is first placed and fixed at the upper limit of the box. Then, the steel plate material to be coated is placed on the bottom surface of the curved plate. The vacuum pump is started to create a vacuum. The steel plate material is adsorbed and fixed by the adsorption plate. Then, the adhesive layer required for coating is applied to the top side of the workpiece. The first drive unit is started to move the steel plate material down and bond it to the side surface of the workpiece to complete the coating operation. Step B: When the adhesive is applied, air bubbles will appear on the surface of the adhesive layer. By activating the moving component on the box, the piercing needle on the moving component moves horizontally from one side of the workpiece to the other, piercing and eliminating the air bubbles on the surface of the adhesive layer. During the operation of the moving component, the linkage component moves synchronously. The power generated by the operation of the linkage component drives the piercing needle on the moving component to move up and down reciprocally while moving horizontally. The piercing needle on the moving component is inserted into the deeper part of the adhesive layer to pierce the air bubbles in the deeper part of the adhesive layer. At the same time, the generated airflow can also be used to heat and spray out to heat the bottom surface of the connecting box. After the film is applied, it is convenient to wipe and clean the bottom of the connecting box. When the linkage component is running, it can drive the conveying component to run synchronously, so that the defoamer pre-stored in the conveying component is squeezed out and conveyed to the piercing needle to assist in the elimination of air bubbles.

[0015] Compared with the prior art, the present invention provides a coating mechanism for relieving stress on the side of a hydraulic cylinder housing, which has the following beneficial effects: 1. The coating mechanism for stress relief on the side of a hydraulic cylinder housing uses a movable component on the housing to break air bubbles on the top layer of the adhesive layer coated on the workpiece surface, thereby eliminating the air bubbles and preventing the adhesive layer from becoming thinner, which would reduce the bonding strength and cause the adhesive to fall off.

[0016] 2. This coating mechanism for relieving stress on the side of a hydraulic cylinder housing can drive a linkage component to operate synchronously when the moving component is running. The power generated by the operation of the linkage component drives the piercing needle on the moving component to move horizontally and reciprocate up and down. The piercing needle on the moving component is inserted into a deeper part of the adhesive layer to pierce the air bubbles in the deeper part of the adhesive layer, thereby effectively eliminating air bubbles in the entire adhesive layer. At the same time, the generated airflow can be used to heat the bottom surface of the connecting box and spray out to heat the bottom surface of the connecting box, preventing the adhesive on the piercing needle from adhering to the piercing needle.

[0017] 3. The film-coating mechanism for relieving stress on the side of the hydraulic cylinder housing can drive the conveying component to operate synchronously when the linkage component is running, so that the defoamer pre-stored in the conveying component is squeezed out and conveyed to the puncture needle, thereby further improving the defoaming effect of the moving component.

[0018] The parts of this device not described herein are the same as or can be implemented using existing technologies. This invention uses a moving component to break and eliminate air bubbles generated on the adhesive layer applied to the workpiece surface during the coating process. Simultaneously, the moving component drives the linkage component to operate synchronously, causing the linkage component to drive the piercing needle on the moving component to move up and down reciprocally. At the same time, a small amount of defoamer is added to the conveying component to assist in reaching into the bottom area of ​​the adhesive layer to better eliminate air bubbles in the entire adhesive layer, thereby improving the bonding strength of the coated steel plate of the hydraulic cylinder housing and preventing loosening and detachment.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] Reference Figure 1-8 A coating mechanism for relieving stress on the side of a hydraulic cylinder housing includes a housing 1, a workpiece 2 disposed on the housing 1, an arc-shaped plate 3 for coating the workpiece 2 disposed above the workpiece 2, a first driving part 4 disposed on the top of the arc-shaped plate 3, and further includes: a moving component 5 disposed on the housing 1 between the workpiece 2 and the arc-shaped plate 3 for puncturing air bubbles generated on the adhesive applied to the surface of the workpiece 2 before coating; the moving component 5 includes a power mechanism installed on the inner wall of one side of the housing 1, one end of the power mechanism is connected to a connecting box 54, a puncturing needle 55 is slidably connected to the bottom inner wall of the connecting box 54, and the bottom surface of the connecting box 54 is an arc-shaped surface.

[0024] In this invention, workpiece 2 is a hydraulic cylinder housing. During the coating operation, workpiece 2 is pre-positioned and fixed at the upper limit of the housing 1. Then, the steel plate material to be coated is placed on the bottom surface of the arc plate 3. A vacuum is drawn by starting the vacuum pump 11, and the steel plate material is adsorbed and positioned by the adsorption plate 10 to facilitate the subsequent coating operation. Then, the adhesive layer required for coating is applied to the top side of workpiece 2, so that the steel plate material can be moved down and bonded to the side surface of workpiece 2 by starting the first drive unit 4, thus completing the coating operation. When the adhesive is applied, air bubbles will be generated on the surface of the adhesive layer. By starting the moving component 5 on the housing 1, the piercing needle 55 on the moving component 5 moves horizontally from one side of workpiece 2 to the other side to puncture and eliminate the air bubbles on the surface of the adhesive layer. This automated operation is convenient to use and avoids the phenomenon that the generated air bubbles cause the adhesive layer to become thinner, thereby reducing the bonding strength. During the operation of the moving component 5, the linkage component 6 is driven to operate synchronously. The power generated by the operation of the linkage component 6 drives the piercing needle 55 on the moving component 5 to move horizontally and reciprocate up and down. The piercing needle 55 on the moving component 5 is inserted into a deeper part of the adhesive layer to pierce the air bubbles in the deeper part of the adhesive layer, thereby effectively eliminating air bubbles in the entire adhesive layer. At the same time, the generated airflow can also be used to heat the bottom surface of the connecting box 54, preventing the adhesive on the piercing needle 55 from adhering to the piercing needle 55, improving the smoothness of the operation of the piercing needle 55, and facilitating the wiping and cleaning of the bottom of the connecting box 54 after the film is coated. The operation of the linkage component 6 can drive the conveying component 7 to operate synchronously, causing the defoaming agent pre-stored in the conveying component 7 to be squeezed out and conveyed to the piercing needle 55, thereby further improving the defoaming effect of the moving component 5.

[0025] It should be noted that the arc-shaped surface at the bottom of the connecting box 54 is close to the top surface of the workpiece 2, and the length of the multiple piercing needles 55 is adapted to the arc-shaped surface of the workpiece 2. In the initial state, the bottom of the piercing needle 55 is in contact with the adhesive layer, which can perform preliminary scratching treatment on the air bubbles generated on the surface. When the piercing needle 55 moves down, it extends into the bottom of the adhesive layer but does not contact the workpiece 2, which can pierce and eliminate the air bubbles at the bottom layer of the workpiece 2.

[0026] In a preferred embodiment, refer to Figure 1-8The power mechanism includes a second drive unit 51 fixed to the inner wall of one side of the housing 1. A connecting block 52 is fixed to the output end of the second drive unit 51. A connecting rod 53 is installed on one side of the connecting block 52. The end of the connecting rod 53 is fixedly connected to the connecting box 54. A linkage assembly 6 is provided on one side of the second drive unit 51. The linkage assembly 6 includes a telescopic rod 61 fixed to the inner wall of one side of the housing 1. One end of the telescopic rod 61 is fixedly connected to the connecting rod 53. An air intake 62 is provided at one end of the telescopic rod 61. A valve 63 is provided on the air intake 62. An air supply pipe 64 is installed on the telescopic rod 61. The end of the air supply pipe 64 is connected to the connecting box 54. An L-shaped plate 65 is installed on the inner wall of the connecting box 54. An impeller 66 is provided inside the connecting box 54. A rotating rod 67 is fixed at the shaft center of the impeller 66. One end of the rotating rod 67 is rotatably connected to the inner wall of the connecting box 54 via a bearing. One end of the rotating rod 67 passes through the L-shaped plate 65 and is provided with a reciprocating component. The reciprocating component includes an eccentric wheel 68 fixed to the end of the rotating rod 67. A T-shaped rod 69 is attached to the surface of the eccentric wheel 68. A connecting plate 692 is fixed to the bottom of the T-shaped rod 69. A return spring 691 is fixed to the top surface of the T-shaped rod 69 on one side of the eccentric wheel 68. The end of the return spring 691 is fixedly connected to the inner wall of the connecting box 54. The interior of the connecting box 54 forms a separate cavity through the L-shaped plate 65. An air vent 8 is provided on one side of the connecting box 54. An air vent pipe 81 is fixed to the bottom surface of the L-shaped plate 65. The air vent pipe 81 is L-shaped and is provided with a heating tube. An inlet 9 is provided at the top of the liquid outlet 75.

[0027] Specifically, the second drive unit 51 uses a cylinder or electric push rod as a drive source instead of a drive. During operation, activating the second drive unit 51 causes the connecting block 52 to move and extend. This allows the interior of the telescopic rod 61 to draw in and store gas through the air intake port 62. Then, the gas inside the telescopic rod 61 is compressed and transported out through the air supply pipe 64 to the interior of the connecting box 54. The valve 63 is a one-way valve, and the L-shaped plate 65 allows the interior of the connecting box 54 to form a separate cavity, facilitating gas delivery. The air can drive the impeller 66 to rotate, which in turn drives the eccentric wheel 68 to rotate. Combined with the return spring 691, the piercing needle 55 slides up and down on the inner wall of the connecting box 54. With this structure, compared with the traditional method of manually cleaning air bubbles, the operation is more convenient and the work efficiency is improved. Moreover, through the cooperation of the moving component 5 and the linkage component 6, compared with some existing technologies for eliminating air bubbles, this mechanism can reach deep into the bottom of the adhesive layer to pierce and eliminate air bubbles deep in the adhesive layer. The effect of removing air bubbles is better and avoids the impact of air bubbles deep in the adhesive layer on the bonding strength of the steel material coating.

[0028] It should be noted that because the air storage capacity inside the telescopic rod 61 is greater than the volume of the connecting box 54, a strong airflow impact force is generated when the air is transported through the relatively narrow air delivery pipe 64. This force can blow the impeller 66, driving its structure. The gas blown into the cavity formed at the L-shaped plate 65 drives the impeller 66 to rotate and is then discharged through the outlet pipe 81. A heating element is installed on the outlet pipe 81 and connected to an external power source to heat the gas discharged from the outlet pipe 81. The heating temperature can be controlled by a temperature sensor. The device performs real-time monitoring. Hot air enters the interior of the connecting box 54 and heats the arc-shaped surface at the bottom of the connecting box 54. This allows the adhesive that adheres during the de-bubbling process of the puncture needle 55 to remain on the arc-shaped surface. As the arc-shaped surface is heated, it prevents the adhesive from hardening and affecting the lifting and lowering of the puncture needle 55. It also facilitates wiping and cleaning of the arc-shaped surface after the film is applied. The vent hole 8 allows for easy venting, preventing the connecting box 54 from being sealed and unable to release air. The small vent hole 8 prevents excessive heat from dissipating.

[0029] In a preferred embodiment, refer to Figure 1-8 The top of the connecting plate 692 is provided with a conveying assembly 7 for intermittently adding defoaming agent to the puncture needle 55. The conveying assembly 7 includes a slide rod 71 fixed to the top of the connecting plate 692. The slide rod 71 is slidably connected inside the connecting cylinder 72. A piston 73 is slidably connected inside the connecting cylinder 72. The bottom of the piston 73 is fixedly connected to the slide rod 71. A drainage tube 74 is fixed to the top of the connecting cylinder 72. The end of the drainage tube 74 passes through the connecting box 54 and communicates with the liquid outlet 75. The liquid outlet 75 is installed on the top surface of the connecting box 54. A conveying component is provided on one side of the connecting cylinder 72. The conveying component includes a liquid storage box 76 provided on the connecting cylinder 72. A liquid guide tube 77 is fixed to one end of the liquid storage box 76. The end of the liquid guide tube 77 passes through the connecting plate 692 and communicates with the puncture needle 55.

[0030] Specifically, when the connecting plate 692 moves downward, it can drive the slide bar 71 to move synchronously. The adsorption force generated inside the connecting cylinder 72 adsorbs the defoamer stored at the liquid inlet 9 into the connecting cylinder 72. When it moves upward, it is transported to the inside of the connecting plate 692 through the liquid guide tube 77, and then diverted to multiple puncture needles 55 to make intermittent movements, squeezing and delivering a small amount of defoamer. In this way, in conjunction with the operation of the puncture needles 55, the effect of eliminating bubbles in the adhesive layer is further improved. The defoamer used does not contain silicone and will not affect the adhesive layer.

[0031] In a preferred embodiment, refer to Figure 1-8An adsorption plate 10 is provided on the bottom surface of the arc plate 3. The end of the adsorption plate 10 is connected to a vacuum pump 11 through a pipe. The vacuum pump 11 is installed on the mounting plate 12. The bottom of the mounting plate 12 is fixedly connected to the arc plate 3, and the top of the mounting plate 12 is fixedly connected to the first driving part 4. A clamping cylinder 13 is provided on the box body 1. A limit block 14 is provided on the box body 1 at the other end of the workpiece 2. A collection box 15 is provided on the box body 1 on one side of the limit block 14.

[0032] Specifically, after the workpiece 2 is placed, the clamping cylinder 13 can be activated to clamp and limit one end of the workpiece 2, while the other end is limited by the limiting block 14 to prevent the workpiece 2 from shifting. The collection box 15 is set up to facilitate the collection of residual adhesive on the connecting box 54 when the device is reset. When the steel plate material is picked up, the adsorption plate 10 can be attached to the surface of the curved steel plate material. The vacuum pump 11 is activated to draw a vacuum, which can then adsorb and fix the steel plate material. Then, the first driving unit 4 is activated to drive the steel plate material to move down and fix the corresponding adhesive layer. The clamping cylinder 13 and the first driving unit 4 can be driven by a cylinder or other driving source instead of a drive.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

During the operation of the moving component (5), the moving component (5) drives the linkage component (6) to operate synchronously. The power generated by the operation of the linkage component (6) drives the piercing needle (55) on the moving component (5), which can puncture the air bubbles on the surface of the adhesive layer while moving horizontally. The downward reciprocating motion utilizes the piercing needle (55) on the moving component (5) to insert into the deeper part of the adhesive layer, piercing the air bubbles present in the deeper part of the adhesive layer. At the same time, the generated airflow can be used for heating treatment and sprayed out to heat the bottom surface of the connecting box (54). After the film is completed, it is convenient to wipe and clean the bottom of the connecting box (54). When the linkage component (6) is running, it can drive the conveying component (7) to run synchronously, so that the defoamer pre-stored in the conveying component (7) is squeezed out and conveyed to the piercing needle (55) to assist in the elimination of air bubbles.
