TECHNICAL FIELD

[0001] The utility model relates to numerical control machine tool technical field especially is related to a numerical control machine tool system panel frame and numerical control machine tool. BACKGROUND

[0002] With the development of science and technology, large numerical control machine tools are increasingly used in industrial production. An operator controls the operation of the numerical control machine tool by operating a machine tool control panel fixedly installed on the front of the machine tool. The existing numerical control machine tool includes a main body, a protective cover and a control panel. The protective cover is coupled to the outside of the main body to prevent metal chips and powder from splashing when the main body is performing metal cutting. An observation window is formed in the protective cover to allow the operator to observe the working condition of the main body. Since the operator generally faces the observation window when operating, the side where the observation window is located also serves as the front of the numerical control machine tool. At the same time, the control panel is generally arranged on the outside of the front of the numerical control machine tool to facilitate the operator's operation.

[0003] However, in some processes requiring high machining precision, the operator needs to observe the machining condition of the numerical control machine tool through the observation window from different angles at all times and timely operate the machine tool control panel for machining. However, the control panel of the existing numerical control machine tool is fixedly installed on the front of the main body and cannot be adjusted in angle, or the machine tool control panel can only be rotated in a single direction, which makes it difficult to switch the observation angle while operating the control panel, causing inconvenience to the operator. SUMMARY

[0004] Therefore, the utility model aims to provide a numerical control machine tool system panel frame and a numerical control machine tool.

[0005] The numerical control machine tool system panel frame comprises a support installed on one side of a numerical control machine tool, a system mounting plate for carrying a machine tool operation panel, and a rotating assembly comprising a rotating frame, a first rotating shaft with an axis extending in a vertical direction, a first sleeve, a second rotating shaft and a second sleeve. The first sleeve is sleeved outside the first rotating shaft, and the second sleeve is sleeved outside the second rotating shaft. One of the first rotating shaft or the first sleeve is arranged on the support, and the other is connected to the rotating frame. One of the second rotating shaft or the second sleeve is located on the side of the rotating frame away from the first rotating shaft or the first sleeve, and the other is connected to the system mounting plate.

[0006] The numerical control machine tool system panel frame can be rotated in two opposite directions relative to the machine tool body by setting the first rotating shaft and the second rotating shaft, which expands the rotation angle of the operation panel to meet the operating requirements of the operator.

[0007] Further, the first sleeve is provided with a first through hole extending in the vertical direction, and a positioning groove extending along the circumference of the first through hole is recessed in the inner wall of the first through hole; the outer wall of the first rotating shaft is provided with a positioning ring extending along the circumference thereof; when the first rotating shaft is inserted into the first through hole, the positioning ring and the positioning groove are nested and matched.

[0008] Through the nested matching of the positioning ring and the positioning groove, the connection between the rotating mechanism and the first sleeve is more stable.

[0009] Further, the second sleeve is provided with a second through hole extending in the vertical direction, and the outer wall is provided with a positioning hole extending in the radial direction thereof, the positioning hole being communicated with the second through hole; the outer wall of the second rotating shaft is provided with a plurality of limiting holes extending in the radial direction thereof; the second rotating shaft is inserted into the second through hole, and the axis of the positioning hole and the axis of the limiting hole can coincide.

[0010] Through the above technical solution, when the second sleeve and the second rotating shaft are relatively rotated, the positioning hole and the limiting hole are communicated, and the rotation angle can be locked by inserting the positioning pin.

[0011] Further, the system mounting plate is provided with a containing space on the side close to the support, and the second rotating shaft or the second sleeve is fixedly installed in the containing space.

[0012] Through the above technical solution, the installation space is saved, and the appearance is more beautiful.

[0013] Further, the system mounting plate is provided with an opening on the side away from the support, and the opening is communicated with the containing space.

[0014] Through the above technical solution, the operator can use the operation panel in the containing space through the opening.

[0015] Further, the rotating assembly further comprises an annular ring and a plurality of steel balls; the annular ring is located between the inner wall of the first sleeve and the outer wall of the first rotating shaft, and between the inner wall of the second sleeve and the outer wall of the second rotating shaft; a plurality of ball holes are formed along the circumference of the annular ring; the steel balls are rollingly arranged in the ball holes.

[0016] Through the above technical solution, when the first sleeve and the second sleeve rotate around the first rotating shaft and the second rotating shaft respectively, the annular ring and the steel balls play a damping role, so that the rotation is more stable.

[0017] Further, the annular ring is a bearing steel piece.

[0018] The above technical solutions make the ring more wear-resistant and extend its service life.

[0019] Furthermore, the rotating assembly also includes a pressure cap disposed on top of the first rotating shaft, the pressure cap having its plate surface abutting against the top of the first sleeve.

[0020] The above technical solution ensures that the gland presses against the first sleeve and the first rotating shaft, making the connection more stable.
