Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, and in particular to a CNC lathe for machining. Background Technology

[0002] As one of the most widely used types of CNC lathes, CNC lathes occupy an important position in the field of machining. They are mainly responsible for the precision machining of shaft and disc parts, specifically covering the turning of inner and outer cylindrical surfaces, the forming of inner and outer conical surfaces with arbitrary cone angles, the fine carving of complex rotating inner and outer curved surfaces, and the precise cutting of cylindrical and conical threads.

[0003] In the prior art, such as utility model patent CN209830283U, a CNC lathe specifically designed for machining long-shaft workpieces is disclosed. A movable door is used as the lathe's opening and closing mechanism. This patent innovates upon this by incorporating a hinged structure between the door and the lathe body, allowing the door to flexibly tilt upwards. This design cleverly increases the operating space when loading workpieces onto the lathe, greatly facilitating the loading of long-shaft workpieces. However, the hinged structure is a four-bar linkage, which requires simulation optimization during design and demands high precision in the machining of each link. Utility Model Content

[0004] This utility model provides a CNC lathe for machining, which solves the problems of high machining accuracy requirements and complex design of four-bar articulated structures.

[0005] To solve the above-mentioned technical problems, this utility model provides a CNC lathe for machining, including a frame, a guide plate disposed above the frame, a switch door hinged to the front end of the guide plate, a fixed rod provided on one side of the switch door, and a support rod hinged to one side of the frame, which is connected to the fixed rod through the support rod, so as to support the switch door when it is flipped up.

[0006] In a preferred embodiment, the strut includes a fixed shaft, a first extension tube and a second extension tube fitted on both sides of the fixed shaft, a guide groove provided on the side wall of the first extension tube and the second extension tube, a fixed groove connected to the guide groove on the side of the guide groove, and a protrusion on the fixed shaft that can move along the guide groove and engage with the fixed groove.

[0007] In a preferred embodiment, the front end of the first extension tube is provided with a first fixing seat, and the first fixing seat is provided with a hole for connecting to the fixing rod. The front end of the second extension tube is provided with a second fixing seat, and the second fixing seat is hinged to one side of the frame.

[0008] In a preferred embodiment, a movable groove is provided below the frame and the switch door, and a sealing mechanism for sealing the movable groove is also provided on the frame. The sealing mechanism includes a mounting base mounted on the frame, a guide shaft provided on the mounting base, a sealing plate sleeved on the side of the guide shaft away from the mounting base, and a spring provided on the guide shaft between the sealing plate and the mounting base.

[0009] In a preferred embodiment, a wear-resistant ring is provided on the outside of the sealing plate, and the guide shaft passes through the wear-resistant ring.

[0010] In a preferred embodiment, a flange is provided at the front end of the guide shaft, and a matching hole is provided inside the sealing plate.

[0011] In a preferred embodiment, the wear-resistant ring includes a detachable left ring and a right ring, with a connection hole on the left ring for connecting to the sealing plate.

[0012] The beneficial effects of this utility model are: the hinge method between the door and the guide plate does not need to be designed as a four-bar hinge structure. The door and the guide plate only need a normal hinge method, and the position of the flipped door is fixed by the support rod, thus replacing the original working method. Compared with the original design, it does not require a precise four-bar hinge structure, which can reduce the requirements for machining accuracy. Moreover, multiple fixing grooves are provided on the first and second extension cylinders along the length direction, and the CNC lathe operator can adjust the height of the support rod according to his / her height. Compared with the fixed door height of the four-bar hinge method, it is more convenient for the operator to flip the door upward. Attached Figure Description

Detailed Implementation

[0015] Please see Figure 1-7 As shown, the present application provides a technical solution: a CNC lathe for machining, including a frame 12, a guide plate 13 disposed above the frame 12, a switch door 14 hinged to the front end of the guide plate 13, a fixing rod 15 provided on one side of the switch door 14, and a support rod 2 hinged to one side of the frame 12, which is connected to the fixing rod 15 through the support rod 2, so as to support the switch door 14 when it is flipped up.

[0016] CNC lathes also include control panels, display instruments, tool turrets, etc. CNC lathes are existing technology and will not be described in this solution.

[0017] In this way, the hinge connection between the door 14 and the guide plate 13 does not need to be designed as a four-bar hinge structure. The position of the flipped-up door 14 is fixed by the extension of the support rod 2. Compared with the original design, a precise hinge structure is not required. In a preferred embodiment, the support rod 2 includes a fixed shaft 21, a first extension tube 22 and a second extension tube 23 fitted on both sides of the fixed shaft 21, a guide groove 221 and a fixing groove 222 provided on the side walls of the first extension tube 22 and the second extension tube 23, and a protrusion 24 provided on the fixed shaft 21 that can move along the guide groove 221 and be engaged in the fixing groove 222.

[0018] The way the strut 2 is to extend the first extension tube 22 and the second extension tube 23 to both sides is to extend them. At this time, the protrusion 24 on the fixed shaft 21 moves along the length direction of the guide groove 221. Then, by rotating the fixed shaft 21, the protrusion 24 can be inserted into the fixed groove 222, thus fixing the length of the strut 2.

[0019] By providing multiple fixed slots 222 along the length of the first extension tube 22 and the second extension tube 23, the CNC lathe operator can adjust the height of the support rod 2 according to their own height. Compared with the height of the door 14 fixed by the four-bar hinge method, it is more convenient for the operator to flip the door 14 upwards.

[0020] In a preferred embodiment, the front end of the first extension tube 22 is provided with a first fixing seat 25, and the first fixing seat 25 is provided with a hole for connecting to the fixing rod 15. The front end of the second extension tube 23 is provided with a second fixing seat 26, and the second fixing seat 26 is hinged to one side of the frame 12.

[0021] When fixing the door 14, simply fit the hole of the first fixing seat 25 onto the fixing rod 15, so that the support rod 2 can support the door 14. The hinged connection between the second fixing seat 26 and the frame 12 can also be the same as the connection of the first fixing seat 25.

[0022] In a preferred embodiment, a movable groove 121 is provided below the frame 12 and the switch door 14. A sealing mechanism 3 for sealing the movable groove 121 is also provided on the frame 12. The sealing mechanism 3 includes a mounting base 31 mounted on the frame 12, a guide shaft 32 provided on the mounting base 31, a sealing plate 33 sleeved on the side of the guide shaft 32 away from the mounting base 31, and a spring 34 provided on the guide shaft 32 between the sealing plate 33 and the mounting base 31.

[0023] The movable slot can act as a stop for the switch door 14 below. At this time, the switch door 14 is in the closed position. The sealing mechanism 3 can prevent iron filings from falling into the movable slot 121 of the CNC lathe during machining.

[0024] In this way, the sealing plate 33 can move along the direction of the guide shaft 32. Through the elastic force of the spring 34, the sealing plate 33 can be pressed tightly against one side of the switch door 14. In this way, when the CNC lathe is being processed, iron filings are not likely to fall into the movable groove 121 below the switch door 14. Even when the switch door 14 is being processed while it is flipped up and opened, the sealing plate 33 can cover the movable groove 121 to prevent iron filings from falling into the movable groove 121.

[0025] In a preferred embodiment, a wear-resistant ring 35 is provided on the outer side of the sealing plate 33, and the guide shaft 32 passes through the wear-resistant ring 35.

[0026] When the sealing plate 33 moves, the friction mainly comes from the back-and-forth movement of the wear ring 35 and the guide shaft 32. Therefore, by simply improving the machining accuracy of the wear ring 35, the machining accuracy of the sealing plate 33 can be reduced.

[0027] In a preferred embodiment, a flange 36 is provided at the front end of the guide shaft 32, and a matching hole is provided in the sealing plate 33.

[0028] The flange 36 prevents the sealing plate 33 from accidentally detaching from the guide shaft 32.

[0029] In a preferred embodiment, the wear-resistant ring 35 includes a detachable left ring 351 and a right ring 352, with a connection hole 3511 on the left ring 351 for connecting to the sealing plate 33.

[0030] This allows for quick installation of the wear-resistant ring 35 by first inserting the guide shaft 32 into the sealing plate 33, then using screws to install the left ring 351 onto the sealing plate 33 through the connecting hole 3511, and then connecting the right ring 352.

[0031] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
