[0007] A surrounding external frame is arranged outside the device body, a displacement connecting arm is arranged at the outer end of the surrounding external frame, and a manual locking frame is arranged outside the device body.

[0008] The surrounding external frame also includes a vertical limiting frame, a rack and a limiting shaft. The vertical limiting frame is fixedly installed on the side end of the surrounding external frame, the rack is fixedly installed on the inner end of the vertical limiting frame, and the limiting shaft is movably connected to the side end of the vertical limiting frame.

[0009] In some embodiments, a strip-shaped hollow groove structure is opened at the side end of the vertical limit frame, the limit shaft is a columnar structure as a whole, and a flat sheet structure is arranged at the ends of both sides, and the limit shaft passes through the strip-shaped grooves on both sides of the vertical limit frame.

[0010] In some embodiments, the displaceable connecting arm also includes a fixing frame, an adjusting gear, an adaptive support foot, a joint shaft and a rubber pad. The fixing frame is fixedly installed on the side end of the displaceable connecting arm, and the adjusting gear is penetrated by the limiting shaft to establish a movable connection relationship.

[0011] In some of the embodiments, the adaptive support leg is movably connected to the lower end of the displacement connecting arm through a joint axis, the joint axis is movably connected between the adaptive support leg and the displacement connecting arm, and contains a bearing structure inside, and the rubber pad is sleeved on the bottom side of the adaptive support leg.

[0012] In some of the embodiments, the vertical limiting frames and the displacement connecting arms are provided in four groups and are distributed in a cross shape around the periphery of the surrounding external frame.

[0013] In some embodiments, the manual locking frame also includes an insert block and an adjustment rod, the insert block is movably connected to the outer end surface of the manual locking frame through the adjustment rod, the adjustment rod penetrates the manual locking frame and the insert block from top to bottom, and a strip groove is also provided at the position in contact with the manual locking frame.

[0014] In some of the embodiments, the insert blocks and the manual locking frames are provided in four groups, and their overall shape is an arc surface structure, wherein the side of the insert blocks facing the adjacent vertical limit frame is a thin strip structure.

[0015] In some embodiments, the maximum angle that the adaptive support leg can rotate through the joint axis is 40°, and rubber rings are provided on both sides of the joint axis.

[0016] Compared with the prior art, the present invention provides an adsorption-type levelness detection device for assembly of a sheet metal shell of a machine tool:

[0017] An adsorption-type level detection device assembled on a sheet metal shell of a machine tool is provided. By setting a displacement connecting arm, a manual locking frame, an adaptive support foot, an adjustment gear, a vertical limit frame and a surrounding external frame, when the device is used, the operator rotates the level through the support of the main connecting shaft. When the device is placed at a fixed point in a non-magnetic state, the operator keeps the rubber pad parallel to the plane of the installation position and continuously presses down the device body so that the rubber pad and the adaptive support foot transmit downward pressure. If the installation position is not an overall horizontal environment, the higher point contacts the rubber pad first. After the rubber pad is blocked, the adaptive support foot at the corresponding position is squeezed and generates a vertical upward reaction force. The displacement connecting arm is pushed upward, causing the adjustment gear on this side to rotate frictionally through the meshing of the rack. Under the support of the limit shaft, the adjustment gear The wheel keeps moving upwards, and at the same time, the other three sets of displacement connecting arms contact the installation surface in turn in the same way, and push the adjustment gear upward to different degrees according to the height of the contact position of the rubber pad, until the four sets of rubber pads stably contact the installation surface, and the operator moves the plug block in turn according to the position of the adjustment gear, so that the plug block moves vertically upward or downward through the support of the adjustment rod, and then moves the plug block sideways to one end of the adjustment gear, so that the front end of the plug block is inserted into the gap between the adjustment gear and the rack. At this time, the level meter remains horizontal as a whole. When magnetic adsorption installation is required, it is only necessary to push the four sets of displacement connecting arms upwards at the same time, and then rotate the adaptive support feet through the joint axis and expand them outward. At this time, the magnetic suction block protrudes from the middle, and the adsorption installation is completed after aligning with the installation position;

[0018] The above settings and processes can make the device have the following beneficial effects:

[0019] Through the coordination of adaptive support feet, joint shafts, and displacement connecting arms, the support structure of the device can be made more flexible and highly adjustable compared to traditional fixed support structures. Through the coordination of racks, adjustment gears, manual locking frames, and adjustment rods, the device can adapt to the height of the mounting surface by adjusting the position of the gears during fixed-point installation. This ensures the stability of the level even if there is a certain height difference on the mounting surface. This not only improves environmental adaptability and flexibility of use, but also simplifies the level placement steps and reduces the difficulty of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Specifically, Figure 1 Figure 2 as well as Figure 3 As shown, the columnar structure in the middle of the limiting shaft 403 passes through the middle of the vertical limiting frame 401, and the sheet structures on both sides thereof remain at the outer ends of both sides of the vertical limiting frame 401 to ensure that the limiting shaft 403 will not fall out.

[0037] In this embodiment, the adaptive support leg 503 is movably connected to the lower end of the displacement connecting arm 5 through the joint shaft 504, and the joint shaft 504 is movably connected between the adaptive support leg 503 and the displacement connecting arm 5, and contains a bearing structure inside, and the rubber pad 505 is sleeved on the bottom side end of the adaptive support leg 503; the vertical limiting frame 401 and the displacement connecting arm 5 are each provided with four groups, and are distributed in a cross shape around the periphery of the surrounding external frame 4.

When magnetic adsorption installation is required, it is only necessary to push the four sets of displacement connecting arms 5 upward at the same time, and then rotate the adaptive support foot 503 through the joint shaft 504 and expand it outward. At this time, the magnetic block 7 protrudes from the middle, and the adsorption installation is completed after aligning with the mounting position.
