Description

Technical Field

[0001] This invention relates to the field of casting processing technology, specifically to a stabilizing device for casting processing. Background Technology

[0002] Castings are metal parts or semi-finished products obtained by pouring molten metal into a mold and allowing it to cool and solidify. Common casting processes include sand casting, precision casting, die casting, low-pressure casting, gravity casting, and centrifugal casting. Commonly used casting materials include cast iron, cast steel, aluminum alloys, and copper alloys.

[0003] After casting is completed, castings generally require cleaning, heat treatment, machining, surface treatment, inspection, and other processes. Different fixtures are needed to hold the castings in place. This means that users need to constantly switch between different fixtures when processing the castings. This increases the user's workload and affects the processing efficiency of the castings. Furthermore, most of the operation of the fixtures is currently done manually, which can lead to errors and affect the clamping accuracy of the fixtures on the castings. Summary of the Invention

[0014] Compared with the prior art, the present invention provides a stabilizing device for casting processing, which has the following advantages: 1. In use, this invention clamps the cast hollow shaft by cooperating with the clamping turntable and the tailstock. Then, a moving drive motor drives the clamping turntable to rotate, facilitating grinding or other processing of the cast hollow shaft's surface. When quenching is required, an electric push rod is driven to move, moving the clamping turntable, tailstock, and cast hollow shaft. As the tailstock moves, a trapezoidal wedge block drives it to reset, ensuring the end of the cast hollow shaft away from the clamping turntable is no longer obstructed. The clamping turntable and cast hollow shaft then move to a position concentric with the induction hardening mechanism and the receiving plate. Finally, the fixed drive motor and the moving drive motor are activated. The rotating motor drives the clamping turntable to rotate, while the fixed drive motor drives the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw causes the push rod and the receiving plate to move. Since the moving speed of the push rod is greater than that of the receiving plate, the push rod pushes the cast hollow shaft out of the clamping turntable while the receiving plate clamps both ends of the cast hollow shaft. Afterward, the cast hollow shaft passes through the induction hardening mechanism for surface hardening. Then, the push rod completely pushes the cast hollow shaft out. This allows for easy switching of the clamping method for the cast hollow shaft, making it easier for users to process the cast hollow shaft and greatly reducing the frequency of manual operation, thereby improving the processing efficiency of the cast hollow shaft.

[0015] 2. In this invention, when the clamping turntable and tailstock clamp the cast hollow shaft, the rotation of the drive motor is used to rotate the clamping turntable and the cast hollow shaft, thereby facilitating the user's processing of the cast hollow shaft. At the same time, after the electric push rod drives the clamping turntable to be concentric with the receiving plate, the drive motor is restarted. At this time, the drive motor drives the cast hollow shaft to rotate again. With the assistance of the air blowing pipe, the surface debris of the cast hollow shaft is cleaned, thereby improving the efficiency of subsequent quenching of the cast hollow shaft.

[0016] 3. In the initial state, the tailstock is guided by the trapezoidal wedge block and positioned close to the clamping turntable. When the tailstock clamps the cast hollow shaft, it significantly improves the fixing effect on the cast hollow shaft. When the electric push rod drives the clamping turntable to move, the tailstock is in a clamping state on the cast hollow shaft. At this time, the tailstock is connected to the clamping turntable through the cast hollow shaft. When the clamping turntable moves, the tailstock is driven to move synchronously. As the tailstock moves, it slides on the surface of the trapezoidal wedge block. When the tailstock moves to another position of the trapezoidal wedge block, the trapezoidal wedge block can drive the tailstock to reset. At this time, the tailstock and the cast hollow shaft are automatically separated, which facilitates the subsequent quenching of the cast hollow shaft. Attached Figure Description

[0019] 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.

[0020] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a stabilizing device for casting processing.

[0021] Example 1: Please refer to Figures 1-11 A stabilizing device for casting processing includes a square tube frame 1, an induction hardening mechanism 9 on the square tube frame 1, a clamping turntable 2 movably mounted on the square tube frame 1, a tailstock 3 slidably mounted on the other side of the square tube frame 1, the length of the ejector pin on the tailstock 3 being adjustable, a plurality of clamping plates 21 circumferentially distributed on the clamping turntable 2 for clamping objects, the tailstock 3 for clamping one end of the casting, a trapezoidal wedge block 35 slidably mounted on the outer side of the tailstock 3, the trapezoidal wedge block 35 being fixedly mounted on the square tube frame 1, and a reset component mounted on the trapezoidal wedge block 35 for driving the tailstock 3 to reset. The square tube frame 1 is also equipped with a moving drive motor 4, an electric push rod 5, and an air blowing pipe 8. The moving drive motor 4 is used to drive the clamping turntable 2 to rotate, and the air blowing pipe 8 is used to clean the surface of the casting with air. When the electric push rod 5 extends, it can drive the clamping turntable 2 to move along the vertical direction of the square tube frame 1. The square tube frame 1 is also equipped with a moving mechanism 6, which includes a push rod 61, a bidirectional guide screw 62, a receiving plate 63 and a fixed drive motor 64. The fixed drive motor 64 is used to drive the bidirectional guide screw 62 to rotate. The push rod 61 and the receiving plate 63 are slidably mounted on the bidirectional guide screw 62. The push rod 61 is used to push the casting on the clamping turntable 2 toward the receiving plate 63. When the bidirectional guide screw 62 rotates, the push rod 61 and the receiving plate 63 can move in the same direction, and the push rod 61 can move toward the receiving plate 63 at a speed greater than that of the receiving plate 63. The electric actuator 5 includes a clamping stroke and a moving stroke; During the clamping stroke, the electric push rod 5 can drive the clamping plate 21 to move towards the center of the clamping turntable 2; During the travel, the electric push rod 5 drives the clamping turntable 2 to be concentric with the axis of the receiving plate 63 by storing force through the tension spring. During the movement of the clamping turntable 2 driven by the electric push rod 5, the clamping turntable 2 drives the casting to move through the clamping plate 21, and the casting drives the tailstock 3 to move synchronously. When the tailstock 3 moves to the inclined surface position of the trapezoidal wedge block 35, the tailstock 3 releases the clamping of the casting. At this time, the reset member can drive the tailstock 3 to reset. Then, the fixed drive motor 64 drives the bidirectional guide screw 62 to rotate. At this time, the bidirectional guide screw 62 can drive the push rod 61 and the receiving plate 63 to push the casting on the clamping turntable 2 out of the clamping turntable 2 by clamping at both ends, and drive the casting hollow shaft to pass through the induction hardening mechanism 9.

[0022] Initially, the tailstock 3 is positioned at the top horizontal plane of the trapezoidal wedge block 35. The trapezoidal wedge block 35 then presses against the tailstock 3, forcing it to be close to the clamping turntable 2. During use, the user places one end of the cast hollow shaft at the center of the clamping turntable 2 and then drives the electric push rod 5 to perform the clamping stroke. The electric push rod 5 then drives the clamping plate 21 on the clamping turntable 2 to move towards the center of the turntable 2, clamping one end of the cast hollow shaft. The other end of the cast hollow shaft is then tightened by adjusting the length of the ejector pin on the tailstock 3. Finally, the surface of the cast hollow shaft is processed. When other parts of the cast hollow shaft need to be processed, the movable drive motor 4 drives the clamping turntable 2 to rotate, thereby facilitating the processing of different parts of the cast hollow shaft. Then, when the surface of the cast hollow shaft needs to be quenched, the electric push rod 5 is driven to move. At this time, the electric push rod 5 drives the clamping turntable 2, the tailstock 3, and the cast hollow shaft to move along the air blowing pipe 8. When the tailstock 3 moves to the inclined surface of the trapezoidal wedge block 35, the compressive force on the tailstock 3 decreases, and the tailstock 3 gradually separates from one end of the cast hollow shaft. Then, the electric push rod 5 drives the clamping turntable 2, the cast hollow shaft, the receiving plate 63, and the induction hardening mechanism 9 to be concentric. Then, the movable drive motor 4 operates, and the air blowing pipe 8 cleans the surface of the cast hollow shaft. Finally, the fixed drive motor 64 drives the bidirectional guide screw 62 to rotate, bidirectionally... The rotation of the lead screw 62 drives the push rod 61 and the receiving plate 63 to move. Since the moving speed of the push rod 61 is greater than that of the receiving plate 63, the push rod 61, while pushing the casting hollow shaft out of the clamping turntable 2, can also clamp both ends of the casting hollow shaft with the cooperation of the receiving plate 63. Then, the casting hollow shaft is driven by the push rod 61 through the induction hardening mechanism 9 for surface hardening. As the push rod 61 moves, the casting hollow shaft is completely pushed out of the clamping turntable 2, realizing the complete hardening of the casting hollow shaft. This allows for easy switching of the clamping method of the casting hollow shaft, making it easier for users to process the casting hollow shaft, and greatly reducing the frequency of manual operation, thereby improving the processing efficiency of the casting hollow shaft. At the same time, the setting of the air pipe 8 can also clean the surface of the casting hollow shaft, thereby improving the effect of subsequent induction hardening.

[0023] Example 2: See Figures 1-11Unlike the first embodiment described above, the square tube frame 1 is provided with several slide rails, and a sliding frame 22 is rotatably connected to the outer side of the clamping turntable 2. The sliding frame 22 is vertically slidably connected to the slide rails. Several limiting holes are opened around the circumference of the clamping turntable 2, and the clamping plate 21 is slidably connected to the inner side of the limiting holes. A positioning plate 23 is also fixedly connected to the clamping turntable 2. Several fixed rollers 212 are provided on both the positioning plate 23 and the clamping plate 21. A mounting bracket is fixedly connected to the outer side of the electric push rod 5, and a baffle 51 is fixedly connected to the output shaft of the electric push rod 5. The mounting bracket is installed on the square tube frame 1. One end of the clamping plate 21 passes through the limiting hole and is threadedly connected to the clamping screw 24. The clamping screw 24 is rotatably connected to the clamping turntable 2 through a bearing seat, and one end of the clamping screw 24 is fixedly connected to... There is a driven bevel gear 25, and the outer sides of multiple driven bevel gears 25 mesh together with a driving bevel gear 26. The inner side of the driving bevel gear 26 passes through and is fixedly inserted into a hollow round tube 27. The outer side of the hollow round tube 27 is fixedly connected to a clamping gear 28. The outer side of the clamping gear 28 meshes with a rack 29. The rack 29 is fixedly connected to the output shaft of the electric push rod 5. The outer side of the hollow round tube 27 is also rotatably connected to a bearing bracket 211. The bearing bracket 211 is fixedly mounted on a sliding frame 22. A return spring 210 is fixedly connected to one side of the bearing bracket 211. The end of the return spring 210 away from the bearing bracket 211 is fixedly connected to a mounting frame. The return spring 210 applies a pulling force to the bearing bracket 211, so that the bearing bracket 211 maintains a tendency to move closer to the mounting frame. A through hole is provided at the center of the clamping turntable 2, allowing the push rod 61 to pass through the clamping turntable 2 to push the casting. The specific operation is as follows: the push rod 61 first passes through the hollow round tube 27 and the through hole in sequence, and then abuts against one end of the casting. The push rod 61 continues to move, thereby pushing the casting to move and allowing the casting to pass through the induction hardening mechanism 9. When the electric push rod 5 is running, the rack 29 first pushes the clamping gear 28 to rotate to complete the clamping of the casting. Then the rack 29 separates from the clamping gear 28. At this time, the baffle 51 can contact the bearing bracket 211. A toothed ring is provided on the outer side of the clamping turntable 2. The moving drive motor 4 is mounted on the sliding frame 22, and a drive gear 41 is fixedly connected to the output shaft of the moving drive motor 4. The drive gear 41 meshes with the toothed ring on the outer side of the clamping turntable 2. The reset component includes a movable frame 31 and a connecting spring 32. The movable frame 31 is slidably connected to the square tube frame 1. The tailstock 3 is slidably connected to the movable frame 31 via a guide rail. The tailstock 3 can move linearly along the guide rail towards or away from the clamping turntable 2. The movable frame 31 is vertically slidably connected to the slide rail on the square tube frame 1. The tailstock 3 and the clamping turntable 2 are concentrically arranged. The connecting spring 32 is symmetrically fixedly connected to the bottom of the tailstock 3. Initially, the connecting spring 32 is in a compressed state. The connecting spring 32 applies a spring force to the tailstock 3, so that the tailstock 3 maintains a tendency to move away from the clamping turntable 2. The end of the connecting spring 32 away from the tailstock 3 is fixedly connected to the movable frame 31. A bending plate 33 is fixedly connected to the tailstock 3. A limiting roller 34 is provided on the inner side of the bending plate 33. The limiting roller 34 is rotatably connected to the trapezoidal wedge block 35. The trapezoidal wedge block 35 is fixedly connected to the square tube frame 1. A limiting bolt 36 is fixedly connected to the trapezoidal wedge block 35. A connecting piece 37 is slidably connected to the limiting bolt 36. The connecting piece 37 is slidably engaged with the bending plate 33. A fixing spring 38 is fixedly connected to the outer side of the connecting piece 37. The end of the fixing spring 38 away from the connecting piece 37 is fixedly connected to the trapezoidal wedge block 35 through a support block. When the bending plate 33 moves along the guide rail on the square tube frame 1, it can drive the connector 37 to slide along the limit bolt 36, and at the same time the connector 37 squeezes the fixing spring 38. When the limiting roller 34 moves to the inclined surface of the trapezoidal wedge block 35, it pushes the tailstock 3 away from the clamping turntable 2 under the elastic force of the connecting spring 32, thus releasing the clamping of the casting.

[0024] The spring force of the fixed spring 38 is greater than that of the connecting spring 32. When the tailstock 3 loosens its clamping force on the casting, the tailstock 3 can return to its initial state. In the initial state, the end of the trapezoidal wedge block 35 is horizontally pressed against the limiting roller 34, the bending plate 33, and the tailstock 3. At this time, the connecting spring 32 is in the state of being compressed to its limit, and the tailstock 3 is also located on the side of the moving frame 31 close to the clamping turntable 2. In use, one end of the cast hollow shaft is placed on the positioning plate 23, and then the electric push rod 5 is driven to perform the clamping stroke. At this time, the electric push rod 5 drives the rack 29 to move, the rack 29 moves and drives the clamping gear 28 to rotate, the clamping gear 28 rotates and drives the hollow tube 27 to rotate, the hollow tube 27 rotates and drives the driving bevel gear 26 to rotate, the driving bevel gear 26 rotates and drives the driven bevel gear 25 to rotate, the driven bevel gear 25 rotates and drives the clamping screw 24 to rotate, the clamping screw 24 rotates and drives the clamping plate 21 to move along the limiting hole. The clamping plate 21 moves to clamp the cast hollow shaft, and then the tailstock 3 is used to tighten the other end of the cast hollow shaft. After that, the surface of the cast hollow shaft is processed.

[0025] When it is necessary to process other surfaces of the cast hollow shaft, the drive motor 4 drives the drive gear 41 to rotate, and the rotation of the drive gear 41 drives the gear ring and the clamping turntable 2 to rotate, thereby realizing the processing of other surfaces of the cast hollow shaft.

[0026] When the electric push rod 5 moves, the rack 29 separates from the clamping gear 28. At this time, the baffle 51 on the electric push rod 5 contacts the bearing bracket 211 and drives the bearing bracket 211, the clamping turntable 2, and the sliding bracket 22 to move along the slide rail. At this time, the return spring 210 is stretched, thereby moving the clamping turntable 2 and the casting hollow shaft to the concentric position of the induction hardening mechanism 9. Since the tailstock 3 is in a state of pressing against the casting hollow shaft at this time, the tailstock 3 is driven to move when the clamping turntable 2 moves. The movement of the tailstock 3 drives the moving bracket 31, the bending plate 33, and the connecting piece 37 to move along the slide rail. Meanwhile, the limiting roller 34 rolls on the surface of the trapezoidal wedge block 35, and the connecting piece moves 37 to compress the fixing spring 38. When the limiting roller 34 moves to the inclined surface of the trapezoidal wedge block 35, the compressive force of the trapezoidal wedge block 35 on the bending plate 33, the limiting roller 34, and the connecting spring 32 decreases. At this time, the connecting spring 32 rebounds, thereby forcing the tailstock 3 to gradually separate from one end of the cast hollow shaft. After the tailstock 3 separates from the cast hollow shaft, the fixing spring 38 drives the tailstock 3 to reset, thereby realizing the automatic separation of the tailstock 3 from the cast hollow shaft, which facilitates the subsequent quenching of the cast hollow shaft.

[0027] It should be noted that a magnet is provided on the side of the clamping turntable 2 near the clamping gear 28, and a magnet is also provided on the side of the clamping gear 28 near the clamping turntable 2. The magnet on the clamping turntable 2 is located at the end point of the circumferential movement of the clamping gear 28. After the clamping gear 28 rotates multiple times to complete the clamping, the magnet on the clamping turntable 2 can attract the magnet on the clamping gear 28 to lock the clamping gear 28.

[0028] Example 3, see Figures 1-11 Unlike Embodiment 2 described above, the bidirectional lead screw 62 is rotatably connected to the square tube frame 1 via a bearing seat. The bidirectional lead screw 62 has two sets of leads with different pitches. The groove spacing near the top rod 61 is larger than the groove spacing near the receiving plate 63. A fixed drive motor 64 is installed at one end of the bidirectional lead screw 62, mounted on a bearing seat at that end. The output shaft of the fixed drive motor 64 is fixedly connected to the bidirectional lead screw 62. A connecting plate 622 is threaded onto the bidirectional lead screw 62. One end of the connecting plate 622 is slidably connected to the slide rail, and the other end of the connecting plate 622 is fixedly connected to the top rod 61. The inner side of the top rod 61 is provided with a slide groove, and a slide rod 611 is slidably connected to the inner side of the slide groove. A short spring 612 is fixedly connected to the slide rod 611. The end of the short spring 612 away from the slide rod 611 is fixedly connected to the top rod 61. When the slide rod 611 moves, it can pass through the hollow round tube 27. A sleeve 631 is fixedly connected to one side of the receiving plate 63. The length of the sleeve 631 can be selected according to actual needs, as long as it can support the casting without interfering with the normal operation of the equipment. The inner side of the sleeve 631 is provided with several rolling balls 632. The bottom of the receiving plate 63 is fixedly connected to a slide block. The slide block is threaded at the end of the bidirectional guide screw 62 away from the connecting plate 622. The outer side of the receiving plate 63 is provided with a placement seat 633. The placement seat 633 is fixedly connected to the square tube frame 1. When the casting needs to be quenched, the receiving plate 63, the top rod 61, and the induction quenching mechanism 9 are arranged concentrically. The air blowing pipe 8 is installed on the square tube frame 1, and several air blowing nozzles are provided on the air blowing pipe 8. The air blowing pipe 8 is connected to an external air compressor. When the electric push rod 5 moves, the clamping turntable 2, the cast hollow shaft and the receiving plate 63, and the induction hardening mechanism 9 are concentric. Then, the moving drive motor 4 and the air pipe 8 are started. The moving drive motor 4 drives the drive gear 41 to rotate, which in turn drives the clamping turntable 2 to rotate. The rotation of the clamping turntable 2 drives the cast hollow shaft to rotate. At this time, the air pipe 8 can clean the surface of the cast hollow shaft. Then, the fixed drive motor 64 drives the bidirectional guide screw 62 to rotate. The rotation of the bidirectional guide screw 62 drives the receiving plate 63 and the push rod 61 to move. The movement of the push rod 61 causes the slide rod 611 to insert into the hollow round tube 27. Since the moving speed of the push rod 61 is greater than the moving speed of the receiving plate 63, the slide rod 611, in cooperation with the short spring 612 and the slide groove, presses one end of the cast hollow shaft. During the pressing process, the slide rod 611 pushes the cast hollow shaft toward the receiving plate 63. Then, with the cooperation of the sleeve 631, both ends of the cast hollow shaft are clamped. Then, as the push rod 61 moves, the cast hollow shaft slowly passes through the induction hardening mechanism 9. At this time, the induction hardening mechanism 9 quenches it. When the push rod 61 completely pushes the cast hollow shaft out of the induction hardening mechanism 9, the placement seat 633 receives one end of the cast hollow shaft.
