The drying methods of engine casings on the market mostly use wind knife water cutting or fixed-point compressed air water cutting, which can remove most of the liquid on the surface of the cylinder and in the cylinder. However, since the moisture cannot be blown dry quickly, there is still moisture remaining on the surface of the cylinder, and the problem of residual water stains on the surface of the cylinder cannot be solved. Therefore, there is a patent number: 202021517785.7, and the patent name is a vacuum drying equipment. The structure includes a box body and a box cover, a workpiece placement table is provided in the box body, and the box cover is slidably arranged on one side of the box body. After the box cover is closed on the box body, a sealed space is formed in the box body, and a plurality of heating tubes are provided on the inner wall of the box cover. A vent is provided on the body, and a vacuum pump is connected to the vent. The vacuum pump performs vacuum treatment on the sealed space formed by the box cover and the box body. However, this structure still has the following problems during use: 1. The engine casing needs to be manually and accurately inserted into the workpiece placement table. Since a box cover is provided on the side of the workpiece placement table and a guide rail is provided on the top, the placement of the workpiece is restricted, which may easily lead to the workpiece being placed inappropriately, affecting the closing of the box cover in the later stage.

[0027] Preferably, in order to facilitate movement, two guide roller brackets 25 are arranged at intervals in the annular frame 5, and one or more guide rollers 29 are rotatably connected in each guide roller bracket 25. Two guide roller brackets 30 are arranged at intervals in the upper table 401, and one or more guide rollers 31 are rotatably connected in each guide roller bracket 20.

[0028] Preferably, the upper cover lifting module 3 comprises a second cylinder 301, an upper cylinder plate 302, a lower cylinder plate 303 and four lifting rods 304, four guide sleeves 305 are arranged on the lower cylinder plate 303, the second cylinder 301 is fixed to the lower cylinder plate 303, the piston rod of the second cylinder 301 is connected to the upper cylinder plate 302, the upper ends of the four lifting rods 304 are fixed to the upper cylinder plate 302, and the four lifting rods 304 are respectively movably plugged into the corresponding guide sleeves 305. 5, the lower ends of the four lifting rods 304 are fixed on the top of the upper cover body 2. In this embodiment, the specific working principle of the upper cover lifting module 3 is as follows: the control cabinet 103 drives the second cylinder 301 to work, and the piston rod of the second cylinder 301 rises and falls, driving the upper cylinder plate 302 to rise and fall, and at the same time driving the four lifting rods 304 to rise and fall. The lifting rods 304 synchronously drive the upper cover body 2 below to rise and fall, so as to form a sealed chamber when the upper cover body 2 is lowered to fully contact the surface of the vacuum plate 7.

[0029] The overall working principle of this structure is as follows: first, place the workpiece to be vacuum dried on the movable plate 22 (in the initial state, the movable plate 22 is located on the upper table 401, and the left slider 16 and the right slider 17 are located on the left and right sides of the movable plate 22), first drive the left cylinder 18 and the right cylinder 19 on both sides to advance, and at the same time drive the left chuck 20 and the right chuck 21 to extend at the same time to clamp the movable plate 22, then drive the first cylinder 23 on both sides to work to drive the piston rod of the first cylinder 23 to move horizontally, and finally drive the left slider 16 and the right slider 17 to move the clamped movable plate 22 backwards close to the vacuum plate 7 until the movable plate 22 moves into place (that is, the two positioning sensors 9 detect the signal The movable plate 22 is in place after the number is reached), at which point the movable plate 22 is just above the vacuum plate 7, and then the left cylinder 18 and the right cylinder 19 on both sides are driven to retreat, ensuring that the left chuck 20 and the right chuck 21 are separated from the movable plate 22, and then the upper cover lifting module 3 is driven to work, and the upper cover body 2 is moved down until it is completely in contact with the upper surface of the vacuum plate 7 to form a sealed chamber. At this time, the annular frame 5, the annular heating wire 6, the movable plate 22 and the workpiece are all located in the sealed chamber, and then the annular heating wire 6 is driven to work, and the vacuum generating device 13 is driven to work synchronously, the internal sealed chamber is vacuumed, the sealed chamber is vacuum heated, the workpiece is vacuumed, sealed, heated and surface dried, and after completion , the vacuum generating device 13 and the annular heating wire 6 stop working, first drive the air intake device 14 to work for air intake, then drive the upper cover lifting module 3 to lift the upper cover body 2, and then drive the left cylinder 18 and the right cylinder 19 on both sides to advance, and at the same time drive the left chuck 20 and the right chuck 21 to extend at the same time to clamp the movable plate 22, drive the first cylinder 23 to work, and finally drive the left slider 16 and the right slider 17 to move the clamped movable plate 22 forward away from the vacuum plate 7, that is, transport it to the upper table 401. After the user removes the processed workpiece, he puts a new workpiece on it, and realizes the automatic drying of the workpiece by this reciprocating operation. This structure moves the placement position of the workpiece to the vacuum drying area In the front position, the vacuum drying area is separated from the loading area, which can avoid the safety hazard when the equipment is working when the workpiece is placed. Moreover, since the size of the movable plate 22 is smaller than the size of the vacuum plate 7, and the vacuum plate 7 cooperates with the upper cover body 2 to form a sealed chamber, the movable plate 22 can be moved to the sealed chamber, and the moving position of the movable plate 22 is limited by adding a positioning sensor 9 to avoid the movable plate 22 not moving into place and affecting the covering problem of the vacuum plate 7 and the upper cover body 2, which ultimately facilitates the operation of the equipment, makes the operation of the entire equipment more convenient, and is safer to use. It also realizes automatic feeding and conveying of workpieces, which is convenient for manual or robotic clamping of workpieces in the later stage.

[0030] It should be noted that the annular heating wire 6 may not be used, and the drying may be performed directly by vacuuming, and the annular heating wire 6 may be added to increase the drying time and efficiency.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
