DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0019] In addition, in the application, the terms "first", "second", and other similar terms do not imply any order, quantity, and importance, but are only used to distinguish different elements, and the terms "upper", "lower", "left", "right", and other similar terms are only the positional relationship in the drawings.

[0020] As Figure 1 shown, the acid pickling and passivation cleaning equipment for preventing dry burning of electromagnetic valve parts production provided by the embodiments of the present application comprises: a cleaning pool 1, a guide assembly 2, a suspension assembly 3, and a driving assembly 4. The cleaning pool 1 comprises a plurality of upwardly open accommodating cavities for accommodating cleaning liquid, and each accommodating cavity is provided with a driving assembly 4 above. The guide assembly 2 is used for supporting and guiding the suspension assembly 3. The suspension assembly 3 is provided in plurality, used for supporting the parts to be processed and driving the parts to be processed to move in the horizontal direction. When the suspension assembly 3 is installed on the guide assembly 2, it can move along the direction defined by the guide assembly 2. The driving assembly 4 is used for driving the parts to be processed to move in the vertical direction.

[0021] With this setup, after the part to be processed is mounted on the suspension assembly 3, the suspension assembly 3 is moved on the guide assembly 2 by the conveying assembly (not shown in the figure). When the suspension assembly 3 moves to the area where the drive assembly 4 is located, the drive assembly 4 drives the part to be processed to move downward, so that the part to be processed enters the receiving cavity in the cleaning tank 1 for cleaning. After cleaning, the drive assembly 4 drives the part to be processed back to the initial position. Subsequently, the suspension assembly 3 drives the part to move to the next working area.

[0022] It should be noted that the aforementioned conveying components can be one or more of conveyor belts, chains, and belts. Whether the suspension assembly 3 has moved to the area where the drive assembly 4 is located can be detected by sensors or touch switches.

[0023] like Figure 2 As shown, in one embodiment of this application, the guide component 2 includes a guide rail 21 and a pulley 22. The pulley 22 is rotatably mounted on the suspension component 3, and the pulley 22 cooperates with the guide rail 21 to guide the suspension component 3.

[0024] like Figure 3 As shown, in one embodiment of this application, the suspension assembly 3 includes a bracket 31, a pull rod 34, a support plate 35, a support boss 36, a hanging plate 37, a hook 38, and an elastic element A39. The bracket 31 serves as the support component of the entire suspension assembly 3 and cooperates with the guide assembly 2 to achieve support and guidance. The support plate 35 is rotatably mounted below the bracket 31. The support plate 35 has a slot for accommodating the pull rod 34. The support boss 36 is fixedly mounted on the pull rod 34. The diameter of the platform 36 is larger than the width of the slot, so that when the pull rod 34 is located in the slot, the pull rod 34 can be supported by the support plate 35 and the support boss 36; the hanging plate 37 is fixedly connected to the bottom of the pull rod 34, and several hooks 38 for suspending the parts to be processed are fixedly connected to the hanging plate 37; one end of the elastic element A39 is fixedly connected to the bracket 31, and the other end of the elastic element A39 is fixedly connected to the support plate 35; the elastic element A39 applies a force toward the pull rod 34 to the support plate 35; With this configuration, when the pull rod 34 is located in the slot within the support plate 35 and the support boss 36 is located above the slot, the pull rod 34 and the workpiece to be processed can be supported by the support plate 35. When the support plate 35 rotates away from the pull rod 34 at a certain angle, the pull rod 34 loses its support and can move up and down.

[0025] As described above, when the support plate 35 rotates away from the pull rod 34 by a certain angle, the pull rod 34 loses its support. At this time, the pull rod 34 is connected to the drive assembly 4, and the pull rod 34 can be driven by the drive assembly 4 to move in the vertical direction.

[0026] Therefore, such as Figure 4As shown, in one embodiment of this application, the driving component 4 includes a horizontal guide rail 41, a support column 42, a vertical guide rail 43, a horizontal slider 44, a vertical slider A 45, a vertical slider B 46, and a pusher 47. The horizontal guide rail 41 is horizontally arranged, the horizontal slider 44 is slidably engaged with the horizontal guide rail 41, the vertical guide rail 43 is fixedly connected to the horizontal slider 44, the vertical slider B 46 is slidably engaged with the vertical guide rail 43, the pusher 47 is fixedly connected to the vertical slider B 46, the support column 42 is fixedly connected to the horizontal guide rail 41, and a plurality of horizontal guide rods 53 are slidably connected inside the support column 42 and fixedly connected to the vertical guide rail 43. A vertical cylinder 54 is installed on the vertical guide rail 43, and the output shaft of the vertical cylinder 54 is connected to the vertical slider B 46. A horizontal cylinder 55 is installed on the support column 42, and the output shaft of the horizontal cylinder 55 is connected to the vertical guide rail 43. With this configuration, as the support plate 35 rotates away from the pull rod 34, the horizontal cylinder 55 drives the vertical guide rail 43 to move toward the pull rod 34. Thus, when the pull rod 34 loses the support of the support plate 35, the pusher pliers 47 will support the vertical guide rail 43. At this time, the vertical cylinder 54 can drive the vertical slider B46 to move downward, allowing the workpiece to be processed to enter the cleaning tank 1 and complete the cleaning work.

[0027] like Figure 3 As shown, in one embodiment of this application, the pull rod 34 is provided with a plurality of circumferentially distributed spiral grooves, and a steering device 33 is sleeved on the pull rod 34. The steering device 33 is fixedly connected to the bracket 31 through a plurality of support rods 32. The steering device 33 cooperates with the spiral grooves so that when the pull rod 34 moves along its axial direction, the pull rod 34 will rotate. With this configuration, when the drive component 4 moves the pull rod 34, the pull rod 34 will also cause the workpiece to be processed to rotate in the cleaning tank 1, thereby increasing the cleaning efficiency and cleaning effect.

[0028] like Figure 5 As shown, in one embodiment of this application, the steering gear 33 includes a cover 331, a mounting base 332, and ball bearings 333. Each spiral groove contains a ball bearing 333. The mounting base 332 has several grooves that correspond one-to-one with the ball bearings 333. The ball bearings 333 are located in the grooves. The cover 331 is fixedly connected to the mounting base 332 and is used to seal the vertical opening of the groove. The cover 331 is also fixedly connected to the support rod 32.

[0029] like Figure 6As shown, in one embodiment of the present application, the clamping groove in the support plate 35 comprises a straight slot section 351, an inclined slot section 352 and a pushing fitting section 353, and the vertical slider B46 is rotationally connected with a converter 48, wherein the width of the straight slot section 351 is smaller than the diameter of the support boss 36, and the width of the straight slot section 351 is greater than the width of the pushing clamp 47, the width of the inclined slot section 352 is greater than the width of the support boss 36, and the width of the inclined slot section 352 is smaller than the width of the pushing fitting section 353, when the vertical slider B46 moves towards the support plate 35, the converter 48 will be in contact with the pushing fitting section 353; In this way, Figure 7 As shown, when the vertical slider B46 moves towards the support plate 35, the converter 48 will be in contact with the pushing fitting section 353, and at the same time, a part of the pushing clamp 47 has been located below the support boss 36, at this time, the vertical slider B46 continues to move, the converter 48 will push the entire support plate 35 to rotate, at this time, the support plate 35 and the pushing clamp 47 jointly support the support boss 36, when the vertical slider B46 continues to move, the contact area between the support plate 35 and the support boss 36 becomes smaller and smaller, and the contact area between the pushing clamp 47 and the support boss 36 becomes larger and larger, until the support plate 35 is completely separated from the support boss 36, at this time, the vertical slider B46 can be driven downward by the vertical cylinder 54; As shown, Figure 8 When the vertical cylinder 54 drives the vertical slider B46 to move upward, the hook 38 first contacts the pushing fitting section 353, under the pushing of the pushing fitting section 353, the converter 48 moves downward, then the support boss 36 contacts the inclined slot section 352, so that the support plate 35 rotates towards the direction away from the support boss 36, when the support boss 36 moves above the straight slot section 351, under the action of the elastic member A39, the support plate 35 returns to the initial position, at this time, the vertical slider B46 returns to the initial position by the horizontal cylinder 55, the support boss 36 falls on the support plate 35 again, and the support plate 35 supports the support boss 36 again. As described above, in the conversion process from "the support plate 35 supports the support boss 36" to "the pushing clamp 47 supports the support boss 36", only the vertical cylinder 54 and the horizontal cylinder 55 are needed to drive, without additional driving mechanism, and the vertical cylinder 54 is also used to drive the workpiece to rise or fall.

[0030] As shown, Figure 4As shown, in one embodiment of the present application, a limiting block 52 is mounted on the vertical sliding block B 46 to limit the converter 48, a vertical sliding block A 45 is slidingly mounted in the vertical guide rail 43, an elastic member B 50 is mounted between the vertical sliding block A 45 and the vertical sliding block B 46, the bottom of the vertical sliding block B 46 is further fixedly connected with an elastic member guide rod 51 for positioning the elastic member B 50, and the bottom of the converter 48 is rotatably connected with a connecting rod 49, which is rotatably connected with the vertical sliding block A 45.

[0031] Therefore, under the action of the elastic member B 50, the vertical sliding block A 45 always has a tendency to approach the vertical sliding block B 46, and the converter 48 also has a tendency to be in close contact with the limiting block 52.

[0032] Finally, it should be noted that: the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made shall be included in the protection scope of the present application.
