Description

Technical Field

[0001] This utility model relates to the field of machine tool column technology, specifically a vertical machining column structure. Background Technology

[0002] The column is one of the five core components of a machine tool and an important structural component. The column is usually mounted on the machine tool base and supports the machining spindle box by connecting to the bed, satisfying the spindle's Z-axis movement. Herringbone columns are commonly used. The column is generally made of cast iron or welded steel plate and has highly stable performance, capable of bearing the weight of the upper part of the machine tool and various machining forces.

[0003] A search revealed that patent document CN222569902U discloses a machine tool column with a protective cover structure, including a column base, a column body fixedly mounted above the column base (the column body being suspended in the air), a machining base movably mounted on the front of the column body for mounting a machining head, a lifting structure vertically mounted on the front of the column body for driving the lifting movement of the machining base, and a protective cover structure positioned between the machining base surface and the column base to prevent chips and coolant from contacting the lifting structure. The protective cover structure is telescopic. This invention utilizes a protective cover structure positioned on the front of the column to separate chips and coolant from the lifting structure, preventing contact between the chips and coolant generated during machining, thus protecting the lifting structure from damage, improving overall machining accuracy and production efficiency, and extending the service life of the lifting structure.

[0004] However, the protective cover structure in this utility model can only protect the bottom of the machining spindle box. When the spindle box moves downward, the top of the spindle box lacks protection, and foreign objects generated during machining can enter the lifting mechanism, making the protection incomplete and insufficient. Therefore, a vertical machining column structure is proposed to solve the problems mentioned above. Utility Model Content

This solves the problem of incomplete protection in existing machine tool column mechanisms.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vertical machining column structure, comprising a column body, a lifting mechanism provided on the front side of the column body, a spindle base fixedly installed on the front side of the column body via the lifting mechanism, an annular mounting plate fixedly installed on the front side of the column body around the spindle base, sliding grooves provided on the left and right inner walls of the annular mounting plate, two sets of protective mechanisms symmetrically distributed above and below the spindle base provided on the inner side of the annular mounting plate, and symmetrically distributed limiting mechanisms provided at the top and bottom of the spindle base; the upper protective mechanism includes a fixed baffle and several stacked movable baffles, the fixed baffle being fixedly installed on the inner top wall of the annular mounting plate, the several movable baffles being Z-shaped and slidably installed in the sliding grooves on both sides and nested together, and a top plate fixedly installed at the bottom of the last movable baffle, which is fixed to the top of the spindle base via the limiting mechanism.

[0007] Furthermore, the lifting mechanism includes a drive motor, a threaded rod, and two guide rails. The drive motor is fixedly installed on the top of the column body with its output end facing downwards. The threaded rod is rotatably installed on the inner bottom wall of the column body with its top end fixedly connected to the output end of the drive motor. Both guide rails are fixedly installed on the front side of the column body and located inside the annular mounting plate. The main shaft base is slidably installed on the front side of the guide rails and threadedly installed on the outer side of the threaded rod.

[0008] Furthermore, the aforementioned limiting mechanism includes a mounting block, an inner groove of which is provided. A cross-shaped limiting block is movably mounted on the inner side of the movable groove. The front and rear ends of the limiting block extend to the front and rear sides of the mounting block, respectively. The rear side of the limiting block is located at the top of the top plate and forms a limiting position therewith. A spring is fixedly installed between the front side of the limiting block and the front wall of the inner side of the movable groove.

[0009] Furthermore, the rear end of the limiting block is arc-shaped, and the front end of the limiting block is provided with a pull ring.

[0010] Furthermore, side baffles are fixedly installed at both ends of the spindle base by two positioning screws. Both side baffles extend into the slide groove, and the length of the side baffles is adapted to the size of the spindle base.

[0011] Furthermore, a positioning hole is provided on the front side of the side panel, and the positioning screw is located in the positioning hole with a fixing nut threaded at its front end.

[0012] Furthermore, hooks are fixedly installed on the top left and right sides of the column body, and weight reduction holes are opened on the left, right, and rear three sides of the column body.

[0013] Compared with the prior art, this utility model provides a vertical processing column structure, which has the following beneficial effects: This vertical machining column structure, through the setting of a ring mounting plate and the combination of upper and lower protective mechanisms, allows the upper and lower movable baffles to retract and expand respectively when the spindle base moves up and down, effectively protecting the lifting mechanism exposed above and below the spindle base. In addition, the side baffles on the left and right sides of the spindle base provide further comprehensive protection for the gaps on the left and right sides of the spindle base, preventing the waste chips and debris generated during machining from entering the lifting mechanism and affecting machining accuracy and production efficiency. This solves the problem of incomplete protection in existing machine tool column mechanisms. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 6This embodiment of a vertical machining column structure includes a column body 1. A lifting mechanism 2 is provided on the front side of the column body 1. A spindle base 3 is fixedly installed on the front side of the column body 1 through the lifting mechanism 2. An annular mounting plate 4 is fixedly installed on the front side of the column body 1, located around the spindle base 3. Sliding grooves 5 are provided on the left and right inner walls of the annular mounting plate 4. Two sets of protective mechanisms 6 are provided on the inner side of the annular mounting plate 4, respectively located above and below the spindle base 3 and symmetrically distributed. A symmetrically distributed limiting mechanism 7 is provided at the top and bottom of the spindle base 3. The upper protective mechanism 6 includes a fixed baffle 61 and several stacked... The movable baffle 62 and the fixed baffle 61 are fixedly installed on the inner top wall of the annular mounting plate 4. Several movable baffles 62 are Z-shaped and are slidably installed in the sliding grooves 5 on both sides and are nested together. The bottom of the last movable baffle 62 is fixedly installed with a top plate 63 that is fixed to the top of the spindle base 3 by a limiting mechanism 7. Two sets of upper and lower protective mechanisms 6 provide comprehensive protection for the upper and lower parts of the spindle base 3. When the spindle base 3 moves up and down, the spindle base 3 pulls the upper and lower top plates 63, thereby causing the several movable baffles 62 above and below to retract and unfold respectively, so as to keep protecting the lifting mechanism 2 exposed above and below the spindle base 3 at all times.

[0018] The lifting mechanism 2 includes a drive motor 21, a threaded rod 22, and two guide rails 23. The drive motor 21 is fixedly installed on the top of the column body 1 with its output end facing downward. The threaded rod 22 is rotatably installed on the inner bottom wall of the column body 1 with its top end fixedly connected to the output end of the drive motor 21. The two guide rails 23 are fixedly installed on the front side of the column body 1 and located inside the annular mounting plate 4. The spindle base 3 is slidably installed on the front side of the guide rails 23 and threadedly installed on the outer side of the threaded rod 22. The output end of the drive motor 21 rotates to drive the threaded rod 22, thereby driving the spindle base to move along the Z-axis on the guide rails 23.

[0019] In this embodiment, the upper limiting mechanism 7 includes a mounting block 71. A movable groove 72 is provided on the inner side of the mounting block 71. A cross-shaped limiting block 73 is movably installed on the inner side of the movable groove 72. The front and rear ends of the limiting block 73 extend to the front and rear sides of the mounting block 71, respectively. The rear side of the limiting block 73 is located on the top of the top plate 63 and forms a limiting position therewith. A spring 74 is fixedly installed between the front side of the limiting block 73 and the inner front wall of the movable groove 72. By pulling the limiting block 73, the top plate 63 is limited, so that the main shaft base 3 can move up and down and drive the movable baffle 62 to move simultaneously. The top plate 63 can be released from the limiting position simply by pulling the limiting block 73, which facilitates the installation and disassembly of the protective mechanism 6. The rear end of the limiting block 73 is arc-shaped, which makes it easy to push the limiting block 73 to retract into the movable groove 72 when the top plate 63 moves to the inner side of the limiting block 73. The front end of the limiting block 73 is provided with a pull ring, which makes it easier to pull the limiting block 73.

[0020] In this embodiment, side baffles 9 are fixedly installed on both the left and right ends of the spindle base 3 by two positioning screws 8. Both side baffles 9 extend into the slide groove 5, and the length of the side baffles 9 is adapted to the size of the spindle base 3. The two side baffles 9 provide comprehensive protection for the gaps on the left and right sides of the spindle base 3. The front side of the side baffle 9 is provided with a positioning hole 10. The positioning screw 8 is located in the positioning hole 10 and the front end is threaded with a fixing nut 11. The side baffle 9 can be easily removed by installing and removing the fixing nut 11. The positioning hole 10 has enough room to move the side baffle 9 into the slide groove when it is inserted.

[0021] In this embodiment, hooks 12 are fixedly installed on both the left and right sides of the top of the column body 1. The hooks 12 facilitate the lifting of the column body 1 for installation. Weight reduction holes 13 are opened on the left, right and rear sides of the column body 1. The inside of the column body 1 is hollow and reinforced with ribs to reduce the overall weight while ensuring the stability of the column body 1.

[0022] The working principle of the above embodiments is as follows: With the ring mounting plate 4 and the two sets of upper and lower protective mechanisms 6, when the spindle base 3 moves up and down, the two sets of movable baffles 62 retract and expand respectively, effectively protecting the lifting mechanism 2 exposed above and below the spindle base 3. Together with the side baffles 9 on the left and right sides of the spindle base 3, the gaps on the left and right sides of the spindle base 3 are further fully protected, preventing the waste chips and debris generated during processing from entering the lifting mechanism 2 and affecting the processing accuracy and production efficiency.

[0023] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented. It should be noted that the orientation or positional relationship indicated herein is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
