Description

Technical Field

[0001] This utility model relates to the field of plunger rust prevention technology, and in particular to a rust prevention treatment device for the surface of a plunger. Background Technology

[0002] With the continuous development of technology, the hydraulic plungers used in hydraulic equipment in various industries include cast iron plungers and general cast hollow plungers. However, these plungers have low surface hardness and are not wear-resistant. During use, the surface is prone to scratches. Therefore, the surface is treated after the plunger is manufactured.

[0003] When treating the surface of the plunger for rust prevention, the rust-preventive oil is usually brushed onto the plunger manually. Over time, the efficiency will only decrease, and it is time-consuming and labor-intensive, which will affect the overall production progress. Therefore, there is an urgent need for a rust prevention treatment device for the plunger surface. Utility Model Content

[0004] The purpose of this invention is to address the deficiencies of the prior art by providing a rust prevention treatment device for the surface of a plunger, thereby solving the problems mentioned in the background art.

[0005] A rust-prevention treatment device for a plunger surface includes a base, a drive mechanism mounted on the base, and a coating mechanism mounted on the drive mechanism. The coating mechanism includes a bracket, a second motor, a bidirectional lead screw, a first slider, a limiting rod, an oil reservoir, an oiling sponge, a connecting rod, a spring, and the second slider. The second motor is mounted on the top of the bracket, the bidirectional lead screw is mounted at the output end of the second motor, the first slider consists of two opposing components mounted on the bidirectional lead screw and sliding up and down along the bracket, the limiting rod passes through the first slider, the oil reservoir is mounted at the end of the limiting rod, the oiling sponge is mounted at the end face of the oil outlet of the oil reservoir, the second slider is located on both sides of the first slider and slides up and down along the bracket, the connecting rod is mounted on the oil reservoir and passes through the second slider, and the spring is sleeved on the connecting rod and fixedly connected to the second slider.

[0006] The drive mechanism includes a ring, a gear ring, a gear, and a motor. The ring is rotatably mounted on the base, the gear ring is fixedly mounted on the outer wall of the ring, and the gear is mounted at the output end of the motor and meshes with the gear ring for transmission.

[0007] By adopting the above technical solution, it is convenient to coat plungers of various sizes with anti-rust oil.

[0008] The base has a boss in the middle, which is a frustum structure and its height is higher than that of the ring.

[0009] By adopting the above technical solution, the plunger is supported.

[0010] The vertical cross-section of the oil-coated sponge is larger than that of the oil storage box.

[0011] By adopting the above technical solution, it is possible to coat the plunger sidewall from top to bottom.

[0012] The two upper sliders (slider 2) and the upper slider (slider 1) are set at the same horizontal height, and the two lower sliders (slider 2) and the lower slider (slider 1) are set at the same horizontal height.

[0013] By adopting the above technical solution, the plunger is coated with anti-rust oil.

[0014] The center point of the boss and the center point of the base are on the same vertical line, and the oiling sponge is set towards the vertical center line of the base.

[0015] By adopting the above technical solution, it is possible to coat the plunger with anti-rust oil.

[0016] The beneficial effects of this rust-prevention treatment device for the plunger surface are:

[0017] At this time, the connecting rod can push the oil reservoir and the oiling sponge with the elastic force of the spring, so that the oiling sponge adheres to the surface of the plunger. The second drive motor drives the two sliders to move relative to each other along the middle of the bracket through the double-acting screw. The sliders drive the oil reservoir and the oiling sponge through the limit rod, and then the oiling sponge coats the surface of the plunger with anti-rust oil. By setting the spring, it is not necessary to place the center of the plunger directly in front of the center of the convex part. Even if there is a slight deviation, the normal coating of the plunger can still be guaranteed. In addition, setting two sets of oiling sponges can speed up the oiling efficiency of the plunger and automatically coat the side wall of the plunger with anti-rust oil, saving time and effort.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0022] Reference Figs. 1-2 A rust prevention treatment device for a plunger surface includes a base 1, a drive mechanism mounted on the base 1, and a coating mechanism mounted on the drive mechanism. The coating mechanism includes a bracket 7, a second motor 8, a bidirectional lead screw 9, a first slider 10, a limiting rod 11, an oil storage box 12, an oiling sponge 13, a connecting rod 14, a spring 15, and a second slider 16. The second motor 8 is mounted on the top of the bracket 7, the bidirectional lead screw 9 is mounted at the output end of the second motor 8, two first sliders 10 are mounted opposite each other on the bidirectional lead screw 9 and slide up and down along the bracket 7, the limiting rod 11 passes through the first slider 10, the oil storage box 12 is mounted at the end of the limiting rod 11, the oiling sponge 13 is mounted at the end face of the oil outlet of the oil storage box 12, the second slider 16 is located on both sides of the first slider 10 and slides up and down along the bracket 7, the connecting rod 14 is mounted on the oil storage box 12 and passes through the second slider 16, and the spring 15 is sleeved on the connecting rod 14 and fixedly connected to the second slider 16.

[0023] The drive mechanism includes a ring 3, a gear ring 4, a gear 5, and a motor 6. The ring 3 is rotatably mounted on the base 1, the gear ring 4 is fixedly mounted on the outer wall of the ring 3, and the gear 5 is mounted at the output end of the motor 6 and meshes with the gear ring 4 for transmission.

[0024] When in use, the plunger can be placed longitudinally on the boss 2. Under normal circumstances, because the plunger itself is relatively heavy, it can be stabilized on the boss 2 by its own weight, and no additional limit is needed. Alternatively, depending on the actual size of the plunger, pressure can be applied from the top of the plunger through external brackets or other devices to help stabilize the plunger and complete the limit of the plunger.

[0025] The second slider 16 is elastically connected to the connecting rod 14 via the spring 15. At this time, the connecting rod 14 can push the oil reservoir 12 and the oiling sponge 13 by the elastic force of the spring 15, so that the oiling sponge 13 adheres to the surface of the plunger. The second drive motor 8 drives the two sliders 10 to move relative to each other along the middle of the bracket 7 via the double-acting screw 9. The sliders 10 drive the oil reservoir 12 and the oiling sponge 13 via the limit rod 11, and then apply anti-rust oil to the surface of the plunger through the oiling sponge 13.

[0026] During this period, the drive motor 6 can drive the ring 3, which is fixedly connected to the gear ring 4, to rotate on the base 1 through the gear 5. While the ring 3 is rotating, it can drive the coating mechanism to adjust its position to coat the plunger.

[0027] An oil inlet is provided on the upper surface of the oil reservoir 12, and an oil outlet is provided on the side of the oil reservoir 12 where the oiling sponge 13 is installed. The oil can be allowed to seep out from the oil outlet, so that the oiling sponge 13 can replenish the oil and coat the plunger. Excess oil on the plunger can drip into 1 for collection.

[0028] A boss 2 is provided in the middle of the base 1. The boss 2 is a frustum structure and its height is higher than that of the ring 3. The plunger is raised so that the side wall of the plunger can be coated with anti-rust oil by the oiling sponge 13.

[0029] The vertical cross-section of the oiling sponge 13 is larger than that of the oil storage box 12. The two oiling sponges 13 move relative to each other and move to the middle of the bracket 7. When the two oiling sponges 13 are slightly squeezed against each other, the two oil storage boxes 12 will not touch each other, ensuring that the oiling sponge 13 properly coats the plunger.

[0030] The two upper sliders 16 and the upper slider 10 are set at the same horizontal height, and the two lower sliders 16 and the lower slider 10 are set at the same horizontal height, so that the oil reservoir 12 and the oiling sponge 13 can move up and down stably driven by the sliders 10 and 26 to apply anti-rust oil to the plunger.

[0031] The center point of the boss 2 and the center point of the base 1 are on the same vertical line, and the oiling sponge 13 is set towards the vertical center line of the base 1, which can make the plunger centered. (It should be noted that due to the setting of the spring 15, it is not necessary to place the center of the plunger align with the center of the boss 2. Even if there is a slight deviation, normal coating of the plunger can still be guaranteed.)

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
