[0002] The extrusion cylinder is the core pressure-bearing component in non-ferrous metal (such as aluminum and copper) extrusion forming equipment. Its main function is to contain metal billets (such as aluminum ingots) during the extrusion process and, together with the extrusion shaft (pressure rod), form a closed high-pressure chamber. Under high temperature and high pressure, the metal billet is extruded into products of the required shape, such as pipes, profiles, and plates, through specific orifices in the front die. These are usually large cylindrical components, and multiple processing steps are required during production. The vertical lathe is an important processing device in the extrusion cylinder processing, and corresponding fixtures are needed to clamp and fix the extrusion cylinder during processing.

[0003] Existing vertical lathe fixtures used for extrusion cylinder production have limitations when clamping and fixing extrusion cylinders. Since extrusion cylinders come in various specifications, the fixtures are generally a single, integrated structure. This makes it difficult to arbitrarily disassemble and change the fixture's specifications according to the different specifications of the extrusion cylinders. Therefore, improvements are needed.

[0012] 1. This adjustable vertical lathe fixture for extrusion cylinder production is equipped with a fixed cover plate, a movable slide bar, a fixed pressure plate, and a fixed screw sleeve. By rotating the fixed screw sleeve to remove it from the top of the fixed stud, the fixed pressure plate is removed from the surface of the fixed stud, causing the fixed cover plate to move away from the turntable. The movable slide bar is then removed from between the turntable and the fixed cover plate. A movable slide bar of the corresponding length is replaced according to the part specifications. The replaced movable slide bar is inserted into the corresponding position between the turntable and the fixed cover plate. The fixed cover plate is lowered to fit snugly against the turntable, covering the top of the movable slide bar.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: an adjustable vertical lathe fixture for extrusion cylinder production, including a mounting base 1. A rotating column 2 is rotatably mounted at the center of the mounting base 1 via a bearing. The top of the rotating column 2 passes through the mounting base 1 and is fixedly connected to a turntable 6, which is pressed against the top of the mounting base 1. A fixing plate 17 is fixedly mounted at the center of the top of the turntable 6. A fixing cover plate 8 covers the surface of the fixing plate 17 on the top of the turntable 6. Multiple movable slide bars 9 are provided at equal angles between the turntable 6 and the fixing cover plate 8. Multiple limiting slide grooves 14 are provided at the bottom of the fixing cover plate 8, and the movable slide bars 9 are slidably connected inside the limiting slide grooves 14. By providing the fixing cover plate 8, the movable slide bars 9 are pressed and fixed between the turntable 6 and the fixing cover plate 8, so that the movable slide bars 9 are stuck inside the corresponding limiting slide grooves 14. When the turntable 6 drives the movable slide bars 9 to slide, the movable slide bars 9 slide inside the limiting slide grooves 14, ensuring that the movable slide bars 9 will not tilt or deviate during the sliding process.

[0020] A fixing stud 19 is fixedly connected to the center of the top of the fixing plate 17. A fixing pressure plate 20 is sleeved on the surface of the fixing stud 19 and is pressed against the top of the fixing cover plate 8 and the fixing plate 17. A fixing screw sleeve 21 is threaded through the surface of the fixing stud 19 on the top of the fixing pressure plate 20. Because of the fixing screw sleeve 21, after the fixing cover plate 8 and the fixing plate 17 are placed on the top of the turntable 6 in sequence, the fixing screw sleeve 21 is tightened to press against the top of the fixing plate 17, so that the fixing plate 17 is pressed against the top of the fixing cover plate 8, and the fixing cover plate 8 is fixed on the top of the turntable 6, thereby pressing and fixing the moving slide bar 9 between the turntable 6 and the fixing cover plate 8.

[0021] A worm gear 3 is fixedly connected to the surface of the rotating column 2 inside the mounting base 1. A rotating motor 4 is fixedly connected to one side inside the mounting base 1. A worm 5 is fixedly connected to the output end of the rotating motor 4, and the worm 5 meshes with the worm gear 3. Because of the worm gear 3 and the worm 5, the rotating motor 4 is started to drive the worm 5 to rotate. Through the meshing of the worm gear 3 and the worm 5, the rotating column 2 is controlled to drive the turntable 6 to rotate.

[0022] The top of the turntable 6 is provided with multiple arc-shaped grooves 7 at equal angles. One end of the movable slide bar 9 is fixedly connected to a movable protrusion 10, and the movable protrusion 10 is slidably connected inside the arc-shaped groove 7. By providing the arc-shaped groove 7, when the turntable 6 rotates, it pushes the movable protrusion 10 to slide inside the arc-shaped groove 7, thereby limiting the sliding of the movable protrusion 10 and allowing the movable slide bar 9 to slide along the limiting groove 13, which facilitates the control of the opening or closing of multiple movable slide bars 9.

[0023] The mounting base 1 has multiple limiting grooves 13 at equal angles on its top. The bottom of the movable slide bar 9 away from the movable protrusion 10 is fixedly connected to a limiting slider 11, and the limiting slider 11 is slidably connected inside the limiting groove 13. The top of the movable slide bar 9 away from the movable protrusion 10 is fixedly connected to a clamping post 12. Because of the limiting slider 11, the turntable 6 rotates and pushes the movable slide bar 9 to drive the limiting slider 11 inside the limiting groove 13, thereby limiting the sliding of the movable slide bar 9 and ensuring that the movable slide bar 9 moves in a straight line.

[0024] The inner wall of the fixed cover plate 8 is provided with multiple positioning slots 16, and the outer surface of the fixed plate 17 is fixedly connected with multiple positioning protrusions 18. The positioning protrusions 18 and the positioning slots 16 are correspondingly engaged with each other. Because of the positioning slots 16 and the positioning protrusions 18, when the fixed cover plate 8 is clamped on the surface of the fixed plate 17, the positioning slots 16 are tightly clamped on the surface of the corresponding positioning protrusions 18, ensuring that the fixed cover plate 8 is fixed on the top of the turntable 6 without misalignment or deflection.

[0025] Multiple positioning pins 15 are fixedly installed at equal angles on the top of the fixed cover plate 8. Multiple positioning holes 22 are provided through the surface of the fixed pressure plate 20 at equal angles, and the positioning holes 22 are corresponding to the positioning pins 15 and are engaged with each other. By providing the fixed pressure plate 20 and tightening the fixed screw sleeve 21, the fixed pressure plate 20 is tightly fixed to the top of the fixed cover plate 8, so that the positioning holes 22 are engaged with the corresponding positioning pins 15, ensuring that the fixed pressure plate 20 is fixed to the top of the fixed cover plate 8 without misalignment or deflection.

[0026] The working principle of this utility model is as follows:

[0027] Select a suitable length of movable slide bar 9 according to the specifications of the extrusion cylinder parts. Place the movable slide bar 9 tightly against the top of the turntable 6, so that the movable protrusion 10 and the limiting slider 11 are respectively inserted into the arc-shaped slide groove 7 and the first limiting slide groove 13. Move the fixed cover plate 8 to cover the top of the turntable 6, so that the movable slide bar 9 is inserted into the corresponding second limiting slide groove 14. Then move the fixed pressure plate 20 to cover the top of the fixed cover plate 8, so that the positioning insertion hole 22 is engaged with the surface of the corresponding positioning pin 15. Tighten the fixing screw sleeve 21 to press and fix the fixed pressure plate 20 to the fixed cover plate. After the movable slide bar 9 is pressed and fixed between the turntable 6 and the fixed cover plate 8 at the top, the movable extrusion cylinder part is placed on the top of the mounting base 1 on the outside of multiple clamping columns 12. The control motor 4 drives the worm 5 to rotate. Through the meshing of the worm 5 and the worm wheel 3, the control column 2 drives the turntable 6 to rotate, pushing the movable protrusion 10 to slide inside the corresponding arc-shaped slide groove 7, so that multiple movable slide bars 9 push the clamping columns 12 to unfold and stick to the inner wall of the extrusion cylinder part, clamping and fixing the extrusion cylinder part, which facilitates the processing of the extrusion cylinder part.
