Description

Technical Field

[0001] This invention relates to the technical field of machine tool structures, and in particular to a threaded sleeve machining machine tool. Background Technology

[0002] Threaded sleeves, as a key connecting and reinforcing element, are widely used in machinery manufacturing, aerospace, automotive, energy equipment, and maintenance. During processing, threaded sleeves require a tap to create threads inside them to facilitate use with other bolts, screws, and other structures. However, in traditional processing methods, after the tap passes through the blank, a tap-removal process is required, which involves returning the tap along its original path to separate it from the threaded sleeve. Since the tap-removal operation occurs after the threading process is completed, it only occupies the threading time and does not participate in the threading work itself. This results in wasted time and reduced work efficiency. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a threaded sleeve processing machine tool, the specific technical solution of which is as follows: The present invention provides a threaded sleeve processing machine tool, comprising a turntable and a frame, wherein the turntable has a plurality of fixing positions for fixing blanks, and the turntable rotates to transport the blanks to the position of the frame; The frame has two clamping parts arranged opposite to each other, and a tap is arranged between the two clamping parts. The tap is used to tap the blank. Both ends of the tap are provided with connecting rods for cooperating with the two clamping parts. The tap moves alternately between the two clamping parts via the two connecting rods.

[0004] Furthermore, the cross-sectional shape of the connecting rod is one of ellipse, rhombus, or polygon; The clamping part is a sleeve used in conjunction with the connecting rod, and the sleeve contains an electromagnetic coil.

[0005] Furthermore, two movable seats are arranged opposite each other on the frame, and the movable seats slide within a specified stroke on the frame. The sleeve is rotatably mounted on the movable seats, and the two movable seats are connected by a spring. The frame is equipped with a push unit for providing power for the movement of the movable seat and a power unit for providing power for the rotation of the sleeve.

[0006] Furthermore, the fixed position on the turntable includes a fixed groove formed on the outer circumference of the turntable and two side clamps located in the fixed groove. The two side clamps are used to clamp and fix the blank. The fixed groove is conical in shape. When the two side clamps are close to or away from the axis of the turntable, the two side clamps slide in the fixed groove, and the two side clamps are close to or away from each other. The turntable is hollow inside and communicates with the fixed slot. Several electromagnetic thrusters are provided inside the turntable. The movable end of each electromagnetic thruster is provided with a moving plate. The moving plate is rotatably connected to the two side clamps in the corresponding fixed slot through two connecting arms.

[0007] Furthermore, the bottom of the turntable is provided with a plurality of support plates corresponding to each of the fixing slots, and the support plates are located below or offset from the fixing slots.

[0008] Furthermore, a secondary clamping body is movably disposed on the side clamping body. During the process of the pallet deviating from the fixed groove, the secondary clamping body performs preliminary compression on the blank. The secondary clamping body and the side clamping body are connected by an elastic body.

[0009] Furthermore, two conical strips are provided on each of the opposite side walls of the fixing groove, and the two conical strips are oriented in opposite directions. The side wall of the side clamp is provided with an outward protrusion that cooperates with the two conical strips. When the two side clamps move upward or downward, the conical strips in the fixing groove guide the two side clamps, so that the two side clamps move closer to each other. The two side clamps are connected by an elastic body, and the side clamps are connected to the connecting arm by a slider, which slides vertically on the side clamps.

[0010] Furthermore, one end of the pallet is rotatably mounted on the bottom of the turntable, and the other end of the pallet is used to support the blank. A second slider is slidably arranged on the side wall of the pallet. The moving plate and the second slider are rotatably connected by an adjusting arm, and the adjusting arm and the pallet are connected by an elastic body. The pallet has an arc-shaped groove, the center of which coincides with the axis of the turntable. The turntable has a clamping body at the unloading position. When the pallet moves to the clamping body position, the clamping body slides into the arc-shaped groove and the electromagnetic thruster extends.

[0011] The beneficial effects of this invention are as follows: By making the tap reciprocate up and down, and by using two clamping parts to alternately clamp the tap, it is convenient to complete the tapping of two blanks within one cycle of the tap's reciprocating motion. This avoids the need for wire removal after tapping in the traditional method, and ensures that the tap is in working condition when moving in any direction, simplifying the movement and improving work efficiency. The alternating clamping of the tap by the two clamping parts allows the blank to be moved away normally when the tap is separated from the blank. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 9 As shown, a threaded sleeve processing machine tool of the present invention includes a turntable 1 and a frame 2. The turntable 1 has a plurality of fixing positions for fixing a blank 37. The turntable 1 rotates and transports the blank 37 to the position of the frame 2. Two clamping parts 3 are arranged opposite each other on the frame 2, and a tap 4 is arranged between the two clamping parts 3. The tap 4 is used to tap the blank 37. Both ends of the tap 4 are provided with connecting rods 5 for cooperating with the two clamping parts 3. The tap 4 moves alternately between the two clamping parts 3 via the two connecting rods 5; In this invention, the turntable 1 is located on the side of the frame 2 and rotates horizontally. Several fixed positions on the turntable 1 can be used to install several blanks 37, thereby sequentially conveying the blanks 37 to the position of the frame 2. The two clamping parts 3 on the frame 2 can alternately clamp the two connecting rods 5 on the tap 4, thereby realizing the alternating clamping operation of the tap 4. The two clamping parts 3 are located on the upper and lower sides of the turntable 1, respectively, and the directions of the two clamping parts 3 are opposite. In operation, the turntable 1 rotates and transports the billet 37 to the position of the frame 2. At this time, the billet 37 is aligned with the tap 4 on the frame 2. Taking the tap 4 initially located on the upper clamping part 3 as an example, the upper clamping part 3 moves down and carries the tap 4 and the two connecting rods 5 in a synchronous motion. The tap 4 rotates and uses the threads on its outer wall to tap the billet 37. When the connecting rod 5 on the lower side of the tap 4 passes through the billet 37, the lower connecting rod 5 connects with the lower clamping part 3, and the upper clamping part 3 stops clamping the upper connecting rod 5. The lower clamping part 3 continues to carry the tap 4 down, and the tap 4 continues to rotate until it passes through the billet. At this point, the tapping of the blank 37 is completed. The lower clamping part 3 continues to move the tap 4 until the connecting rod 5 on the upper side of the tap 4 moves out of the blank 37. The turntable 1 rotates and removes the finished tapped blank 37. The blank 37 to be processed is moved back to the position of the frame 2. The lower clamping part 3 moves the tap 4 upward. The tap 4 passes through the blank 37 again and taps the blank 37. The upper clamping part 3 fixes the tap 4 and the lower clamping part 3 separates from the tap 4. Thus, within one cycle of the tap 4 moving up and down, it can perform tapping processing on two blanks 37, avoiding the unwinding operation. It should be noted that when the tap 4 is tapping the blank 37, the tap 4 moves slowly. When the tap 4 is detached from the blank 37, the tap 4 moves faster. This makes it easier for the connecting rod 5 to quickly detach from the blank 37. By making the tap 4 reciprocate up and down, and by having the tap 4 be alternately clamped by the two clamping parts 3, the tapping work of the two blanks 37 can be completed within one cycle of the tap 4's reciprocating up and down movement. This avoids the need for wire removal after tapping in the traditional method, and ensures that the tap 4 is in working condition when moving in any direction, simplifying the movement method and improving work efficiency. The alternating clamping of the tap 4 by the two clamping parts 3 allows the blanks 37 to be moved away normally when the tap 4 is separated from the blanks 37.

[0019] Furthermore, the cross-sectional shape of the connecting rod 5 is one of ellipse, rhombus, or polygon; The clamping part 3 is a sleeve 7 used in conjunction with the connecting rod 5, and the sleeve 7 has an electromagnetic coil inside; The inner wall shape of the sleeve 7 is consistent with the outer shape of the connecting rod 5. When the connecting rod 5 is inserted into the sleeve 7, due to its shape characteristics, the connecting rod 5 and the sleeve 7 can rotate synchronously. Since there is an electromagnetic coil inside the sleeve 7, when the electromagnetic coil is energized, it will generate a magnetic force and attract and fix the connecting rod 5, thereby fixing the tap 4 on the sleeve 7. The rotation and movement of the sleeve 7 will drive the tap 4 to move synchronously. When the electromagnetic coil is de-energized, the sleeve 7 and the connecting rod 5 can separate naturally.

[0020] Furthermore, two movable seats 6 are arranged opposite each other on the frame 2, and the movable seats 6 slide within a specified stroke on the frame 2. The sleeve 7 is rotatably mounted on the movable seats 6, and the two movable seats 6 are connected by a spring 8. The frame 2 is provided with a push unit for providing power for the movement of the movable seat 6 and a power unit for providing power for the rotation of the sleeve 7; The movable seat 6 provides support for the sleeve 7. Since the movable seat 6 slides within a specified stroke on the frame 2, it stops moving when it reaches the end of its stroke. The two movable seats 6 are connected by the spring 8. In the natural state, due to the action of the spring 8, the two movable seats 6 are located at their respective ends and are close to each other. The pushing unit can contact one movable seat 6 and push it away from the other movable seat 6. At this time, the movable seat 6 will carry the sleeve 7 on it to move synchronously. When the pushing unit pushes the movable seat 6 to move in the opposite direction, the two movable seats 6 move closer to each other. When the pushing unit separates from the movable seat 6 and contacts the other movable seat 6, it will push the other movable seat 6 to move. Thus, the spring 8 and the pushing unit can alternately push the two movable seats 6 to move. When one movable seat 6 moves, the other movable seat 6 is in a fixed state and the fixed movable seat 6 is close to the turntable 1. The pushing unit can be a threaded rod 10 rotatably mounted on the frame 2 and a pushing body 9 slidably mounted on the frame 2. The threaded rod 10 passes through the pushing body 9 and is threadedly connected to each other. When the threaded rod 10 is driven to rotate by the motor, the threaded rod 10 will push the pushing body 9 to move. The pushing body 9 will move between the two moving seats 6. The pushing body 9 will push one of the moving seats 6 to move. The power unit includes a worm gear 11 rotatably mounted on the frame 2. Two worm wheels 12 are meshed on the worm gear 11, and each worm wheel 12 is equipped with a worm gear 13. The worm gear 13 is rotatably mounted on the corresponding movable seat 6. A worm wheel 14 is provided on the sleeve 7, and the worm gear 13 is meshed with the corresponding worm wheel 14. When the worm gear 11 is driven to rotate by the motor, the worm gear 11 will drive the sleeve 7 to rotate through the worm wheels 12, worm gear 13 and worm wheel 14. When the movable seat 6 and the sleeve 7 move, the movable seat 6 will drive the worm wheel 12 to move on the worm gear 11 through the worm gear 13, thereby keeping the worm gear 11 and worm wheel 12 in a transmission state.

[0021] Furthermore, the fixing position on the turntable 1 includes a fixing groove formed on the outer circumference of the turntable 1 and two side clamps 15 located in the fixing groove. The two side clamps 15 are used to clamp and fix the blank 37. The fixing groove is conical in shape. When the two side clamps 15 are close to or away from the axis of the turntable 1, the two side clamps 15 slide in the fixing groove, and the two side clamps 15 are close to or away from each other. The turntable 1 is hollow inside and communicates with the fixed groove. Several electromagnetic thrusters 16 are provided inside the turntable 1. The movable end of the electromagnetic thruster 16 is provided with a moving plate 17. The moving plate 17 is rotatably connected to the two side clamps 15 in the corresponding fixed groove through two connecting arms 18. Each side clamp 15 has a clamping groove on its side wall, and clamping teeth are provided in the clamping groove. When the two sides clamp 15 approach each other, the two sides clamp 15 clamp and fix the blank 37 between them. When the two sides clamp 15 separate, the blank 37 between the two sides clamp 15 falls off freely. Since the fixing groove is conical, when the electromagnetic thruster 16 retracts, it will pull the two sides clamp 15 closer to the axis of the turntable 1 through the moving plate 17 and the two connecting arms 18, and the two sides clamp 15 will approach each other, thereby completing the clamping work. Conversely, when the electromagnetic thruster 16 extends, the two sides clamp 15 separate.

[0022] Furthermore, the bottom of the turntable 1 is provided with a plurality of support plates 19 corresponding to each of the fixing slots, and the support plates 19 are located below or offset from the fixing slots; When the two clamps 15 are separated, the billet 37 is placed between the two clamps 15. At this time, the bottom of the billet 37 can contact the support plate 19. The support plate 19 positions and lifts the billet 37, which not only facilitates the positioning effect, but also avoids the operation of manually supporting the billet 37 for a long time. The worker only needs to put the billet 37 between the two clamps 15 to complete the loading work, which simplifies the operation and avoids the injury to the worker caused by the clamping work of the side clamps 15 when the billet 37 is manually supported. When the two clamps 15 approach and clamp the billet 37, the support plate 19 deviates from the fixing groove, thereby exposing the bottom of the billet 37, which makes it convenient for the tap 4 to pass through the billet 37 and move.

[0023] Furthermore, a secondary clamping body 20 is movably disposed on the side clamping body 15. During the process of the pallet 19 deviating from the fixed groove, the secondary clamping body 20 performs preliminary compression on the blank 37. The secondary clamping body 20 and the side clamping body 15 are connected by an elastic body 21. The elastic body 21 provides elastic thrust to the secondary clamp 20, which can slide and insert onto the side clamp 15, or... Figure 8 As shown, the auxiliary clamp 20 is rotatably mounted on the side clamp 15; In use, when the billet 37 is placed between the two clamps 15, the support plate 19 lifts the bottom of the billet 37. As the two clamps 15 move closer to each other, the two clamps 20 first clamp the billet 37. At this time, the support plate 19 can be moved away normally. The two clamps 15 continue to move closer and finally rely on the two clamps 15 to complete the clamping of the billet 37. At this time, the support plate 19 has completed the offset work. Thus, the support plate 19 can be removed before the two clamps 15 clamp the billet 37.

[0024] Furthermore, two conical strips 22 are provided on each of the opposite side walls of the fixing groove, and the two conical strips 22 are oriented in opposite directions. The side wall of the side clamp 15 is provided with an outward protrusion 23 that cooperates with the two conical strips 22. When the two side clamps 15 move upward or downward, the conical strips 22 in the fixing groove guide the two side clamps 15, so that the two side clamps 15 move closer to each other. The two side clamps 15 are connected by an elastic body 24, and the side clamps 15 and the connecting arm 18 are connected by a slider 25, which slides vertically on the side clamps 15. Two cones 22 form a vertical trapezoidal groove, and the outward protrusion 23 is located in the trapezoidal groove. When the outward protrusion 23 moves upward, the inclined area on the upper side of the trapezoidal groove guides the outward protrusion 23, so that the two clamping bodies 15 tend to move closer to each other. When the outward protrusion 23 moves downward, the inclined area on the lower side of the trapezoidal groove also guides the outward protrusion 23, so that the two clamping bodies 15 tend to move closer to each other. Thus, by using the trapezoidal groove, the two clamping bodies 15 can move closer to each other when they move upward or downward. The elastic body 24 provides elastic force to the two clamping bodies 15, keeping the outer protrusion 23 within the corresponding two tapered bars 22. When tapping, regardless of whether the force exerted by the tap 4 on the blank 37 is upward or downward, the side clamping bodies 15 will tend to move upward or downward. At this time, the tapered bars 22 and the outer protrusion 23 can make the two clamping bodies 15 closer together, that is, the clamping force of the two clamping bodies 15 on the blank 37 is stronger. Thus, the clamping stability of the blank 37 can be greatly improved regardless of whether the tapping direction of the blank 37 is upward or downward, and the blank 37 can be prevented from slipping and moving.

[0025] Furthermore, one end of the pallet 19 is rotatably mounted on the bottom of the turntable 1, and the other end of the pallet 19 is used to support the blank 37. A slider 29 is slidably arranged on the side wall of the pallet 19. The moving plate 17 and the slider 29 are rotatably connected by an adjusting arm 26, and the adjusting arm 26 and the pallet 19 are connected by an elastic body 30. The pallet 19 is provided with an arc-shaped groove 27, the center of which coincides with the axis of the turntable 1. The unloading position of the turntable 1 is provided with a clamping body 28. When the pallet 19 moves to the position of the clamping body 28, the clamping body 28 slides into the arc-shaped groove 27 and the electromagnetic thruster 16 extends. In its natural state, slider 29 is located at one end of its stroke. At this time, using elastic body 30, slider 29 and support plate 19 can remain relatively stationary. When electromagnetic thruster 16 extends, moving plate 17 will pull support plate 19 to rotate through adjusting arm 26. The end of support plate 19 away from turntable 1 will gradually move to the bottom of the fixed groove. When electromagnetic thruster 16 retracts, moving plate 17 will push support plate 19 to rotate in the opposite direction through adjusting arm 26. The end of support plate 19 will deviate from the fixed groove. Since the movement of the pallet 19 is powered by the electromagnetic thruster 16, when the billet 37 is placed between the two clamps 15, the electromagnetic thruster 16 retracts and pulls the two clamps 15 closer to each other. The pallet 19 moves synchronously, and the two clamps 20 first fix the billet 37. At this time, the side clamps 15 have not yet fixed the billet 37, and the pallet 19 deviates from the fixing groove. As the electromagnetic thruster 16 continues to retract, the two clamps 15 will come into contact with the billet 37. Thus, after the pallet 19 deviates from the billet 37, the two clamps 15 fix the billet 37, avoiding the situation where the pallet 19 has not yet shifted when the two clamps 15 have completed fixing, or the pallet 19 has shifted before the two clamps 15 have completed fixing, causing the billet 37 to slip. When the turntable 1 rotates and moves the billet 37 to the unloading position, the pallet 19 moves to the position of the clamp 28, and the clamp 28 slides into the arc-shaped groove 27. At this time, the clamp 28 fixes the pallet 19. When the electromagnetic actuator 16 extends, the pallet 19 cannot move. At this time, the adjusting arm 26 will pull the slider 29 to slide on the pallet 19, and the elastic body 30 will undergo elastic deformation. The clamps 15 on both sides will gradually separate from each other. Since the pallet 19 will not lift the bottom of the billet 37 at this time, the billet 37 can fall off naturally, and the billet 37 achieves the effect of automatic unloading.

[0026] Furthermore, a core column 31 is inserted through the middle of the turntable 1, and the turntable 1 is rotatably mounted on the core column 31. The clamping body 28 is fixed relative to the core column 31. Several arc-shaped conductors 32 are provided on the outer wall of the core column 31 on the inner side of the turntable 1. Each electromagnetic thruster 16 is provided with a conductive sheet 33. When the conductive sheet 33 contacts the arc-shaped conductor 32, the electromagnetic thruster 16 is energized and retracts. When the conductive sheet 33 is located between two arc-shaped conductors 32, the electromagnetic thruster 16 is de-energized and extends. The electromagnetic thruster 16 has a spring, an electromagnetic coil and an iron core inside. When energized, the electromagnetic coil generates a magnetic force and pulls the iron core into the coil. At this time, the electromagnetic thruster 16 retracts, and the iron core acts as the movable end to pull the moving plate 17 to move. When the electromagnetic thruster 16 is de-energized, the spring pushes the iron core to move outward, and the electromagnetic thruster 16 extends. The core column 31 can support the turntable 1. As the turntable 1 rotates, the conductive plate 33 on the electromagnetic thruster 16 rotates synchronously. When the conductive plate 33 contacts the arc-shaped conductor 32, the electromagnetic thruster 16 is energized and retracts. When the conductive plate 33 moves between two adjacent arc-shaped conductors 32, the electromagnetic thruster 16 is de-energized and extends. Thus, the extension and retraction of the electromagnetic thruster 16 is automatically controlled by the rotation position of the turntable 1. Since the turntable 1 needs to rotate, a transmission sleeve 34 can be set at the bottom of the turntable 1. The transmission sleeve 34 is fitted on the outside of the core column 31. A transmission wheel 35 is set on the transmission sleeve 34, and a drive motor 36 is set on the transmission wheel 35. The drive motor 36 provides rotational power to the transmission wheel 35 and the transmission sleeve 34, thereby driving the turntable 1 to move. In actual use, a worktable can be set at the bottom of the core column 31 and the transmission wheel 35 to facilitate the support of each structure.

[0027] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
