DETAILED DESCRIPTION

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a cross cutting machine of the utility model comprises a cross plate 1 and a plurality of drill bits 2, the cross plate 1 is provided with a plurality of mounting holes in a cross structure, each of the mounting holes is provided with a sealed bearing 15, an inner ring of the sealed bearing 15 is provided with a shaft rod 7, one end of the shaft rod 7 is provided with a gear 3, the gears 3 are meshingly connected, the other end of the shaft rod 7 is fixedly connected with the drill bit 2, the middle of the cross plate 1 is in a rectangular structure with a plurality of support columns 4, a fixing plate 5 is installed above the plurality of support columns 4, a shaft rod 7 is installed on the top surface of the fixing plate 5, a first motor 6 is installed on the bottom surface of the fixing plate 5, a rotating shaft of the first motor 6 is fixedly connected with the corresponding gear 3, and a driving mechanism for pushing the cross plate 1 to move in a "cross" structure is installed on the outside of the shaft rod 7.

[0022] In this embodiment, the driving mechanism includes a second motor 11, an eccentric wheel 14, a fixing ring 10, a ball bearing 16 and a plurality of compression springs 17. The ball bearing 16 is sleeved in the middle of the shaft 7. The fixing ring 10 is arranged on the outside of the ball bearing 16. A plurality of compression springs 17 distributed in an annular structure are installed between the outer ring of the ball bearing 16 and the inner ring of the fixing ring 10. The upper end of the shaft 7 protrudes to form a plurality of pressure-bearing parts 8 distributed in an annular structure. The eccentric wheel 14 is arranged between the two pressure-bearing parts 8. The second motor 11 is arranged above the shaft 7. A connecting frame 13 is installed between the rotating shaft of the second motor 11 and the eccentric wheel 14. A fixing frame 12 is installed between the second motor 11 and the fixing ring 10.

[0023] In this embodiment, positioning rings 9 are installed above and below the shaft rod 7, and the diameter of the positioning rings 9 is larger than the inner ring of the fixing ring 10. The distance between the positioning rings 9 matches the thickness of the fixing ring 10. The positioning rings can be used to position the shaft rod up and down, thereby preventing the shaft rod from falling out of the fixing ring.

[0024] In this embodiment, the pressure-bearing part 8 is arranged in an arc-shaped structure, so that the eccentric wheel can squeeze the shaft rod along the arc-shaped surface along which the pressure-bearing part can move, so that the shaft rod can move in the opposite direction. After the eccentric wheel is removed from the pressure-bearing part, the shaft rod, the fixing plate, the cross plate and the drill bit can be rebounded to their original positions through the rebound of the compression spring, wherein the compression spring is a strong spring, which can better center the shaft rod.

[0025] In this embodiment, the fixing frame 12 is provided with a plurality of fixing holes, and bolts can pass through the fixing holes to fix the fixing frame to the cylinder or other telescopic equipment.

[0026] In this embodiment, the drill bits 2 are arranged without contact with each other, thereby avoiding collision between the drill bits during rotation and increasing safety.

[0027] Among them, the diameter of the drill bit is smaller than the width of the groove to be cut. After starting the first motor, the first motor can synchronously drive the shaft rod through the gear, and the rotation of the shaft rod drives the drill bit. After the rotating drill bit moves downward, it can directly cut out a cross-shaped groove, but a protrusion of a triangular structure will remain between the drill bits. At this time, the second motor can be started. The start of the second motor drives the connecting frame and the eccentric wheel, so that the eccentric wheel can rotate with the shaft rod as the center. During the rotation of the eccentric wheel, the pressed part can be squeezed to make the shaft rod move in the opposite direction. The movement of the shaft rod drives the fixed plate, the support column, the cross plate and the drill bit below, so that the corresponding row of drill bits can cleanly cut the protruding protrusions, while the other row of drill bits can move horizontally and expand the width of the groove. After the eccentric wheel rotates together, the drill bit can move forward, backward, left and right, so that the cross groove can be quickly cut cleanly, and the groove can be widened to the required width, which greatly increases the cutting efficiency without going back and forth and changing the cutting angle.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
