[0034] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.
[0035] Combined with this Figures 1 to 6 The embodiment of the cylinder cavity drying device of the hydraulic cylinder is described below. Specifically, the cylinder cavity drying device of the hydraulic cylinder is constructed as a split structure, which includes a base plate 100, a clamping unit 200, a first driving unit 300, a drying unit 400, a support member 401, a turntable 402, a heating pipe 403, an air duct 404, an air pump 405 and other components. The first driving unit 300 drives the drying unit 400 so that the heating pipe 403 and the two air ducts 404 in the drying unit 400 are extended into the cylinder body. Then, the heating pipe 403 is turned on for heating, and the air pump 405 is turned on at the same time. Gas is ejected from the inner bottom end of the cylinder body to the open end of the cylinder body through the air duct 404, thereby accelerating the flow of gas inside the cylinder body and thereby improving the drying efficiency of the cylinder cavity.
[0036] Please refer to Figures 1 to 6 , a cylinder cavity drying device of a hydraulic cylinder, comprising a bottom plate 100;
[0037] A clamping unit 200 for horizontally clamping and fixing the cylinder body is provided at one end of the bottom plate 100;
[0038] A first driving unit 300 is provided on the bottom plate 100, and a drying unit 400 is connected to the first driving unit 300. The first driving unit 300 is used to drive the drying unit 400 to move along the axis direction of the clamped cylinder. The drying unit 400 is used to extend into the cylinder and dry it.
[0039] The drying unit 400 includes a support member 401, on which a turntable 402 is rotatably connected and is placed coaxially with the cylinder body clamped by the clamping unit 200. A heating tube 403 is fixed to the turntable 402 near the clamping unit 200 and is placed coaxially therewith. A pair of air guide tubes 404 symmetrically placed about the central axis thereof are connected to the turntable 402. The ends of the air guide tubes 404 away from the clamping unit 200 are both connected to an air pump 405. The other ends of the air guide tubes 404 extend horizontally toward the end of the clamping unit 200. At the position where the heating tube 403 is away from the turntable 402, the ends of the air guide tubes 404 away from the turntable 402 are bent 180° toward the ends away from the central axis of the turntable 402.
[0040] The material of the turntable 402 is usually stainless steel, which has excellent corrosion resistance and high temperature resistance and is suitable for long-term use in industrial environments; the surface treatment of the turntable 402 can be polished to ensure smoothness during rotation and reduce friction loss.
[0041] The heating tube 403 can be a resistance heating tube, an infrared heating tube, etc.; the resistance heating tube 403 is usually used to directly heat liquids or gases, and the surface can be chrome-plated or nickel-plated to improve corrosion resistance; the infrared heating tube 403 is used to quickly heat the surface and is suitable for drying, heating and curing applications. In this application, an infrared heating tube is preferred.
[0042] Air pumps 405 are generally devices used to extract gas and eject it from the output end; they create negative pressure or compressed gas through mechanical or pneumatic drive, and then push the gas to where it is needed; common types of air pumps 405 include piston air pumps, diaphragm air pumps, rotary air pumps and vacuum pumps.
[0043] During drying, the cylinder can be placed on the clamping unit 200 for clamping and fixing by manual or robotic means, with the open end of the cylinder facing the turntable 402 horizontally;
[0044] The first driving unit 300 then drives the drying unit 400, causing the heating tube 403 and two air guide tubes 404 in the drying unit 400 to extend into the cylinder. The heating tube 403 is then turned on for heating, and the air pump 405 is simultaneously turned on to eject gas from the inner bottom end of the cylinder toward the open end of the cylinder through the air guide tubes 404, thereby accelerating the flow of gas inside the cylinder and thereby improving the drying efficiency of the cylinder cavity.
[0045] Moreover, the air flow moves from the bottom of the inner side of the cylinder to the open end of the cylinder, and no external dust is blown into the cylinder.
[0046] In order to facilitate uniform drying of the inner cavity of the cylinder, the drying unit 400 also includes a mounting base 406 fixed on the support 401, and the mounting base 406 is located at the end of the turntable 402 away from the clamping unit 200.

[0047] The air guide tube 404 is made of high-temperature resistant plastic material, and the curved section of the air guide tube 404 away from the turntable 402 is located on the side of the heating tube 403 close to the clamping unit 200; that is, when the heating tube 403 and the air guide tube 404 extend into the cylinder body, the heating tube 403 can be prevented from colliding with the bottom surface of the cylinder body and being damaged.
[0048] In order to facilitate the air guide tube 404 to be positioned close to the cylinder inner cavity diameter, so that the air guide tube 404 is close to the inner cavity wall of the cylinder, the drying unit 400 also includes a pair of first slide grooves 4021 on the turntable 402, the first slide grooves 4021 correspond to the air guide tube 404 one by one, and the first slide grooves 4021 are all placed toward the central axis of the turntable 402. The air guide tube 404 is fixedly sleeved with a first slider 408, and the first slider 408 is slidably engaged in the corresponding first slide groove 4021. The air pump 40 5 are fixed to the corresponding first sliders 408. A pair of first telescopic cylinders 409 corresponding to the first sliders 408 are fixed to the turntable 402. The first telescopic cylinders 409 are coaxially arranged with the first slide grooves 4021. The output ends of the first telescopic cylinders 409 are fixed to the corresponding first sliders 408 via connecting bars. The arrangement of the first telescopic cylinders 409 can control the air guide tube 404 to move away from or close to the central axis of the turntable 402, so as to facilitate drying of cylinder cavities with different inner diameters.
[0049] The first driving unit 300 includes a fixing plate 301 fixed on the base plate 100. The fixing plate 301 is located on the side of the mounting seat 406 away from the clamping unit 200. A second telescopic cylinder 302 is installed on the fixing plate 301 and is coaxially placed with the turntable 402. The driving rod at the output end of the second telescopic cylinder 302 is fixed to the mounting seat 406; the movement of the drying unit 400 is driven by the second telescopic cylinder 302.
[0050] The first driving unit 300 also includes a slide rail 303 fixed on the base plate 100. The slide rail 303 is placed coaxially with the turntable 402. A second slider 304 is slidably connected to the slide rail 303, and the lower end of the support member 401 is fixed on the second slider 304; this can improve the guidance of the movement of the drying unit 400.
[0051] The clamping unit 200 includes a support plate 201 vertically fixed on the base plate 100, and the support plate 201 is slidably engaged with a pair of clamping blocks 202 symmetrically placed up and down near the turntable 402 side, and the two clamping blocks 202 are symmetrically placed about the central axis of the turntable 402.

[0052] The second driving unit includes a gear 203 rotatably connected to the side away from the support plate 201. The gear 203 is placed coaxially with the turntable 402. A pair of vertically placed second sliding grooves are provided on the support plate 201. A pair of racks 204 are engaged with the gear 203 and are placed symmetrically about the central axis thereof. The racks 204 are both placed vertically.
