Description

Technical Field

[0001] This invention relates to the field of milling machine technology, specifically to a vertical milling machine for long shaft parts. Background Technology

[0002] A milling machine is a machine tool that uses a milling cutter to machine various surfaces of a workpiece. Typically, the rotation of the milling cutter is the primary motion, while the movement of the workpiece and the milling cutter constitutes the feed motion. It can machine planes, grooves, various curved surfaces, gears, etc. A milling machine is a machine tool that uses a milling cutter to perform milling operations on a workpiece. Besides milling planes, grooves, gear teeth, threads, and splined shafts, milling machines can also machine relatively complex profiles. They are more efficient than planers and are widely used in mechanical manufacturing and repair departments. A milling machine is a versatile machine tool that can machine planes (horizontal and vertical), grooves (keyways, T-slots, dovetail grooves, etc.), geared parts (gears, splined shafts, sprockets), helical surfaces (threads, helical grooves), and various curved surfaces. Furthermore, it can be used for machining rotating surfaces, internal holes, and cutting operations. When a milling machine is working, the workpiece is mounted on the worktable or indexing head, and the rotation of the milling cutter is the primary motion, supplemented by the feed motion of the worktable or milling head, thus obtaining the desired machined surface. Because of its multi-bladed, intermittent cutting mechanism, milling machines have high productivity. Simply put, a milling machine is a machine tool that can perform milling, drilling, and boring operations on workpieces.

[0003] Currently, most existing technologies on the market still have some shortcomings. For example, Chinese patent application number CN201621397444.4 discloses "a milling fixture for shaft parts", which includes a fixture plate, a spindle box, a three-jaw chuck and a tailstock. The spindle box is located on one side of the fixture plate and is fixed to the fixture plate by a rib. The spindle box is connected to the spindle, and the spindle is connected to the three-jaw chuck. A slide rail is opened on the surface of the fixture plate and the tailstock is installed on the slide rail.

[0004] However, the above-mentioned existing technical solutions have the following defects: the shaft parts are mounted on the three-jaw chuck 5, but the three-jaw chuck 5 lacks a protective mechanism, which can easily lead to the three-jaw chuck 5 becoming loose, resulting in unstable clamping and thus affecting the quality of milling.

[0005] Therefore, we propose a vertical milling machine for long shaft parts to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a vertical milling machine for long shaft parts to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a vertical milling machine for long shaft parts, including a machine tool base, wherein a vertical frame is fixedly installed on the upper end of the machine tool base; It also includes a clamping mechanism for clamping and fixing long shaft parts. The clamping mechanism includes two fixed seats arranged symmetrically in the vertical frame. A cylinder is fixedly installed on the upper end of the upper fixed seat and the upper end of the cylinder is fixedly installed on the vertical frame. A motor is provided at the lower end of the lower fixed seat and the lower end of the motor is fixedly installed on the vertical frame. Fixed clamping plates are symmetrically slidably installed on both fixed seats. It also includes a protective mechanism for protecting the long shaft parts after fixing the fixed clamp plate. The protective mechanism includes a stabilizing plate disposed on the side of the fixed seat that is far apart from each other. The ends of the stabilizing plates that are close to each other abut against the fixed clamp plate on the left side, and one corner of the stabilizing plate is set at an angle.

[0008] Preferably, a milling cutter is provided on the right side of the upright frame, a hydraulic cylinder is fixedly installed on the right end of the milling cutter, a movable seat is fixedly installed on the right end of the hydraulic cylinder, the right end of the movable seat is slidably installed on the upright frame, and a lifting device is provided inside the upright frame corresponding to the movable seat.

[0009] Preferably, a hydraulic cylinder 2 is fixedly installed on the left end of each of the fixed clamps on the left side, and the left end of the hydraulic cylinder 2 is fixedly installed on the fixed seats on the upper and lower sides respectively.

[0010] Preferably, each of the fixed clamps has a rack fixedly installed at its rear end, and gears mesh between the racks, with the gears rotatably mounted on opposite ends of the fixed base.

[0011] Preferably, a positioning plate is slidably installed at the end of each of the fixed clamps on the left side that are close to each other, and a magnetic plate is fixedly installed at the left end of each positioning plate.

[0012] Preferably, a guide rod two is slidably mounted through the middle of the magnetic plate, the right end of the guide rod two is fixedly mounted on the fixed clamping plate, and a spring two is sleeved on the outer side of the guide rod two.

[0013] Preferably, an adjusting strip is slidably installed on the rear side of the upper end of the fixed clamp on the left side, and a spring is fixedly installed at the front end of each adjusting strip, with the front end of the spring fixedly installed on the fixed clamp.

[0014] Preferably, a protrusion is fixedly installed at the rear end of the adjusting strip, and a top block is fixedly installed at each of the protrusions at the adjacent ends of the fixing seat.

[0015] Preferably, a guide rod is slidably installed through the middle of each of the stabilizing plates, and the ends of the guide rods that are close to each other are fixedly installed on the fixed base, and a spring is sleeved on the outer side of each guide rod.

[0016] Preferably, magnetic strips are fixedly installed at the ends of the stabilizing plates that are far apart from each other, and a movable magnetic frame is slidably installed on the front side of the upright corresponding to the magnetic strips and magnetic plates.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the long shaft part is placed between the fixed seats on both sides. The hydraulic cylinder one is activated to drive the upper fixed seat to descend, so that the two ends of the long shaft part are respectively abutted and attached to the fixed seats on both sides. The hydraulic cylinder two is activated to drive the left fixed clamping plate to move to the right, and through the rack and gear, drive the right fixed clamping plate to move to the left, so that the long shaft part is automatically clamped and fixed on the fixed seats on both sides, which facilitates subsequent processing and milling operations and has high work efficiency.

[0018] 2. In this invention, after the two fixed clamping plates have finished clamping the long shaft part, the fixed clamping plates will stop moving. The left fixed clamping plate will slide to the left side of the stabilizing plate and stop. At this time, the spring will push the stabilizing plate and the magnetic strip to rise. The right end of the stabilizing plate will abut against the left end of the fixed clamping plate, which will play a stable protective role for the fixed clamping plate and prevent the fixed clamping plate from becoming loose, which would result in the long shaft part on the fixed seat not being firmly clamped. It provides a very stable clamping force when milling the long shaft part, ensuring the quality of milling.

[0019] 3. In this invention, when the left-side fixing clamp moves to the right, it also drives the adjusting bar to move synchronously. The adjusting bar drives the protrusion to move synchronously. The protrusion is blocked by the top block, which pushes the adjusting bar forward. The adjusting bar is made of a deformable elastic material. The right end of the adjusting bar automatically engages in the grooves on the outer surfaces of both ends of the long shaft part, pushing the long shaft part to rotate on the fixing seat. At the same time, when the fixing clamp clamps and fixes the long shaft part, the positioning plate first abuts against and adheres to the outer surfaces of both ends of the long shaft part, and at the same time, it automatically pushes the magnetic... The plate moves outward on the guide rod two, compressing the spring two. At this time, the spring two is in a charged state. When the adjusting bar pushes the long shaft part to rotate on the fixed seat, the grooves on the outer surfaces of both ends of the long shaft part will automatically rotate to the right side of the positioning plate. The right end of the positioning plate is triangular in shape. Under the action of the spring two, it will reset and insert into the grooves on the outer surfaces of both ends of the long shaft part. It cooperates with the fixed clamping plate to clamp and fix the long shaft part on the fixed seat, avoiding the long shaft part from rotating during subsequent milling operations, thereby ensuring the milling quality of the long shaft part.

[0020] 4. In this invention, after clamping and fixing, the hydraulic cylinder pushes the distance between the milling cutter and the long shaft part, activates the lifting device to drive the milling cutter up and down, and starts the motor to drive the fixed seat and the long shaft part to rotate, completing the automatic milling of the long shaft part, improving work efficiency and quality. When disassembling, simply push the movable magnetic frame backward. When the motor drives the long shaft part to rotate, the magnetic strip and magnetic plate will move to the upper and lower sides and the inner front side of the movable magnetic frame, respectively, generating magnetic repulsion on the magnetic strip and magnetic plate. This causes the magnetic strip to drive the stabilizing plate to reset, and the magnetic plate to drive the positioning plate to move out of the groove of the long shaft part. Activating the hydraulic cylinder will drive the fixed clamping plate to reset, thus quickly disassembling the milled long shaft part and improving work efficiency. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-10 This invention provides a technical solution: a vertical milling machine for long shaft parts, including a machine base 1, with a stand 2 fixedly mounted on the upper end of the machine base 1; it also includes a clamping mechanism for clamping and fixing the long shaft parts, the clamping mechanism including two fixed seats 7 arranged symmetrically inside the stand 2, a cylinder 8 fixedly mounted on the upper end of the upper fixed seat 7, the upper end of the cylinder 8 fixedly mounted on the stand 2, a motor 9 fixedly mounted on the lower end of the lower fixed seat 7, the lower end of the motor 9 fixedly mounted on the stand 2, fixed clamping plates 10 symmetrically and slidably mounted on both fixed seats 7, a milling cutter 3 is provided on the right side of the stand 2, a hydraulic cylinder 4 is fixedly mounted on the right end of the milling cutter 3, a movable seat 5 is fixedly mounted on the right end of the hydraulic cylinder 4, the right end of the movable seat 5 is slidably mounted on the stand 2, a lifting device 6 is provided inside the stand 2 corresponding to the movable seat 5, and a hydraulic cylinder 11 is fixedly mounted on the left end of each of the fixed clamping plates 10 on the left side. The left end of the pressure cylinder 11 is fixedly installed on the upper and lower fixed seats 7 respectively. The rear end of each fixed clamping plate 10 is fixedly installed with a rack 12. A gear 13 meshes between the racks 12. The gear 13 is rotatably installed on the opposite ends of the fixed seats 7. The opposite ends of the left fixed clamping plates 10 are slidably installed with positioning plates 18. The left end of each positioning plate 18 is fixedly installed with a magnetic plate 19. A guide rod 20 is slidably installed through the middle of the magnetic plate 19. The right end of the guide rod 20 is fixedly installed on the fixed clamping plate 10, and a spring 21 is sleeved on the outer side of each guide rod 20. An adjusting strip 23 is slidably installed on the rear side of the upper end of each fixed clamping plate 10. A spring 3 24 is fixedly installed at the front end of each adjusting strip 23. The front end of each spring 3 24 is fixedly installed on the fixed clamping plate 10. A protrusion 25 is fixedly installed at the rear end of the adjusting strip 23. A top block 26 is fixedly installed on the opposite ends of each fixed seat 7 corresponding to the protrusion 25. During operation, the long shaft part is placed between the two fixed seats 7. Hydraulic cylinder 4 is activated to lower the upper fixed seat 7, causing both ends of the long shaft part to abut against and fit against the two fixed seats 7. Hydraulic cylinder 11 is then activated to move the left fixed clamping plate 10 to the right, which, through rack 12 and gear 13, moves the right fixed clamping plate 10 to the left, automatically clamping and fixing the long shaft part onto the two fixed seats 7. This facilitates subsequent milling operations and increases work efficiency. When the left fixed clamping plate 10 moves to the right, it also drives the adjusting bar 23 to move synchronously, which in turn drives the protrusion 25 to move synchronously. Block 25 is blocked by top block 26, which pushes adjusting bar 23 forward. Adjusting bar 23 is made of deformable elastic material. The right end of adjusting bar 23 automatically engages in the grooves on the outer surfaces of both ends of the long shaft part, pushing the long shaft part to rotate on the fixed seat 7. At the same time, when the fixed clamping plate 10 clamps and fixes the long shaft part, the positioning plate 18 first abuts against and adheres to the outer surfaces of both ends of the long shaft part. Simultaneously, it automatically pushes magnetic plate 19 to move outward on guide rod 20, compressing spring 21. At this time, spring 21 is in a charged state. When adjusting bar 23 pushes the long shaft part to rotate on the fixed seat 7... During operation, the grooves on the outer surfaces of both ends of the long shaft part automatically rotate to the right side of the positioning plate 18. The right end of the positioning plate 18 is triangular in shape and, under the action of the spring 21, resets and inserts into the grooves on the outer surfaces of both ends of the long shaft part. It cooperates with the fixing clamp 10 to clamp and fix the long shaft part on the fixing seat 7, preventing the long shaft part from rotating during subsequent milling operations, thus ensuring the milling quality of the long shaft part. After clamping and fixing, the hydraulic cylinder 4 pushes the distance between the milling cutter 3 and the long shaft part, starts the lifting device 6 to drive the milling cutter 3 to move up and down, and starts the motor 9 to drive the fixing seat 7 and the long shaft part. The component rotates to complete the automatic milling of the long shaft part, improving work efficiency and quality. When disassembling, simply push the movable magnetic frame 22 backward. When the motor 9 drives the long shaft part to rotate, the magnetic strip 17 and magnetic plate 19 will move to the upper and lower sides and the inner front side of the movable magnetic frame 22 respectively, generating magnetic repulsion on the magnetic strip 17 and magnetic plate 19. This causes the magnetic strip 17 to drive the stabilizing plate 14 to reset, and the magnetic plate 19 to drive the positioning plate 18 to move out of the groove of the long shaft part. Then, the hydraulic cylinder 11 is activated to drive the fixed clamping plate 10 to reset, which can quickly disassemble the milled long shaft part, improving work efficiency.

[0024] As an embodiment of the present invention, a protective mechanism is also provided for protecting the long shaft parts after fixing the fixed clamp plate 10. The protective mechanism includes a stabilizing plate 14 disposed on the opposite side of the fixed seat 7. The ends of the stabilizing plates 14 that are close to each other are abutted against the fixed clamp plate 10 on the left side, and one corner of the stabilizing plate 14 is set at an angle. A guide rod 15 is slidably installed through the middle of the stabilizing plate 14. The ends of the guide rods 15 that are close to each other are fixedly installed on the fixed seat 7, and a spring 16 is sleeved on the outer side of the guide rods 15. A magnetic strip 17 is fixedly installed on the opposite side of the stabilizing plates 14, and a movable magnetic frame 22 is slidably installed on the front side of the frame 2 corresponding to the magnetic strip 17 and the magnetic plate 19. During operation, once the two fixed clamping plates 10 have finished clamping the long shaft part, the fixed clamping plates 10 will stop moving. The left fixed clamping plate 10 will slide on the stabilizing plate 14 to the left side of the stabilizing plate 14 and then stop. At this time, the spring 16 will push the stabilizing plate 14 and the magnetic strip 17 to rise. The right end of the stabilizing plate 14 will abut against the left end of the fixed clamping plate 10, providing stable protection for the fixed clamping plate 10 and preventing the fixed clamping plate 10 from becoming loose, which would result in the long shaft part on the fixed seat 7 not being firmly clamped. It provides a very stable clamping force when milling the long shaft part, ensuring the quality of milling.

[0025] Working principle: The long shaft part is placed between the two fixed seats 7. Hydraulic cylinder 4 is activated to lower the upper fixed seat 7, causing both ends of the long shaft part to abut against the two fixed seats 7. Hydraulic cylinder 11 is activated to move the left fixed clamping plate 10 to the right, which, through rack 12 and gear 13, moves the right fixed clamping plate 10 to the left, automatically clamping and fixing the long shaft part to the two fixed seats 7. This facilitates subsequent milling operations and increases work efficiency. Simultaneously, after the two fixed clamping plates 10 have finished clamping the long shaft part, they stop moving. The left fixed clamping plate 10 slides onto the stabilizing plate 14 and stops on its left side. At this point, spring 16 pushes the stabilizing plate 14 and the magnetic... As bar 17 rises, the right end of stabilizing plate 14 abuts against the left end of fixed clamping plate 10, providing stable protection for fixed clamping plate 10 and preventing it from becoming loose, which could lead to insecure clamping of the long shaft part on fixed seat 7. This provides a very stable clamping force during milling of the long shaft part, ensuring milling quality. When the left fixed clamping plate 10 moves to the right, it also drives adjusting bar 23 to move synchronously. Adjusting bar 23 then drives protrusion 25 to move synchronously. Protrusion 25 is blocked by top block 26, pushing adjusting bar 23 forward. Adjusting bar 23 is made of deformable elastic material, and its right end automatically engages in the grooves on the outer surfaces of both ends of the long shaft part, causing the long shaft part to rotate on fixed seat 7. Meanwhile, when the fixing clamp 10 clamps and fixes the long shaft part, the positioning plate 18 will first abut against and adhere to the outer surfaces of both ends of the long shaft part. At the same time, it will automatically push the magnetic plate 19 to move outward on the guide rod 20, compressing the spring 21. At this time, the spring 21 is in a charged state. When the adjusting bar 23 pushes the long shaft part to rotate on the fixed seat 7, the grooves on the outer surfaces of both ends of the long shaft part will automatically rotate to the right side of the positioning plate 18. The right end of the positioning plate 18 is triangular in shape. Under the action of the spring 21, it will reset and insert into the grooves on the outer surfaces of both ends of the long shaft part, cooperating with the fixing clamp 10 to clamp and fix the long shaft part on the fixed seat 7. This avoids the long shaft part from rotating during subsequent milling operations, thus ensuring the long shaft part... To improve milling quality, after clamping and fixing, hydraulic cylinder 4 increases the distance between the milling cutter 3 and the long shaft part, activating lifting device 6 to move the milling cutter 3 up and down. Motor 9 then rotates the fixed seat 7 and the long shaft part, completing the automatic milling of the long shaft part, thus improving work efficiency and quality. For disassembly, simply push the movable magnetic frame 22 backward. When motor 9 rotates the long shaft part, the magnetic strip 17 and magnetic plate 19 will move to the upper and lower sides and the inner front side of the movable magnetic frame 22, respectively, generating magnetic repulsion on the magnetic strip 17 and magnetic plate 19. This causes the magnetic strip 17 to move the stabilizing plate 14 back to its original position, and the magnetic plate 19 to move the positioning plate 18 out of the groove of the long shaft part. Hydraulic cylinder 11 then activates to reset the fixed clamping plate 10.This allows for quick disassembly of long shaft parts after milling, improving work efficiency.
