Description

Technical Field

[0001] This application relates to the field of sand-vibrating equipment, and in particular to a sand-vibrating machine for castings used in subframes. Background Technology

[0002] The subframe can be seen as the skeleton of the front and rear axles, and is a component of the front and rear axles. The subframe is not a complete frame, but only a bracket that supports the front and rear axles and suspension, allowing the axles and suspension to be connected to the "main frame" through it. It is conventionally called the "subframe".

[0003] There is a cast subframe, referring to Figure 1 The system includes a frame 01 and a reinforcing beam 02 located within the inner ring of the frame 01. The frame 01 is approximately rectangular, with a maximum dimension of 1.6 m in the transverse direction and 1.2 m in the longitudinal direction. The reinforcing beam 02 is positioned transversely along the vehicle body. Mounting rings 03 are located at the four corners of the frame 01, and each mounting ring 03 contains a striking block 05. Striking strips 04 are located near the rear and front of the frame 01, extending transversely along the vehicle body. Each striking strip 04 contains several striking blocks 05. Several striking blocks 05 are also located within the inner ring of the frame 01 and on one side of the reinforcing beam 02.

[0004] After the subframe is cast, the molding sand on the subframe needs to be cleaned off. This can be done by hammering the striking block on the subframe to remove the molding sand from the casting.

[0005] In the process of developing this application, the inventors discovered that the technology has at least the following problems: the current sandblasting machine can only sandblast small subframes, and the sandblasting efficiency is low, making it inconvenient to perform efficient sandblasting operations on the aforementioned large subframes. Summary of the Invention

[0006] To facilitate efficient sand vibrating operations on large subframes, this application provides a sand vibrating machine for casting subframes.

[0007] The technical solution provided in this application for a casting vibrating sand machine for subframes is as follows: A casting vibratory sand machine for subframes, comprising: The base frame includes two vertically arranged support boxes and several connecting beams connecting the two support boxes, wherein the connecting beams are horizontally arranged; A support frame is disposed between two support boxes. The support frame includes a plurality of support beams horizontally disposed between the two support boxes and connecting plates disposed at both ends of the support beams. The connecting plates are connected to the support boxes. The vibration frame includes a connecting steel plate connected to the support beam, a base plate connected to the connecting steel plate, a plurality of positioning heads disposed on the base plate, and a vibration motor disposed on one side of the base plate. One connecting steel plate is disposed on one side of each support beam, and the two ends of the connecting steel plate are elastically connected to the ends of the support beam. The positioning heads are used to insert and fit a mounting ring. A hammering mechanism is mounted on the underframe and is used to hammer a striking block on the subframe.

[0008] By adopting the above technical solution, the entire cast subframe is placed on a vibrating frame. The subframe is positioned by the insertion and engagement of the positioning head and the mounting ring. Then, a hammering mechanism strikes the striking blocks on the subframe, causing the molding sand to crack and detach. The vibrating motor then operates. Due to the elastic connection between the two ends of the connecting steel plate and the end of the support beam, not only can the steel plate itself move significantly, but its deformation also increases the vibration amplitude, allowing the entire vibrating frame to vibrate dramatically. This ensures more thorough detachment of the molding sand from the subframe, improving the efficiency of sand vibration. After sand vibration is complete, all striking blocks are separated, effectively protecting the subframe body.

[0009] Optionally, a flipping mechanism is provided between the two support boxes. The flipping mechanism includes a turntable and a drive assembly for driving the turntable to rotate. One turntable is provided inside each of the two support boxes. The two turntables are coaxially arranged, and the connecting plate is detachably connected to the turntable.

[0010] By adopting the above technical solution, the support frame is set between two turntables. The state of the vibrating frame can be adjusted by rotating the turntables, which facilitates the loading and unloading of the subframe. At the same time, during the operation of the vibrating motor, the turntable drives the subframe to rotate, which makes the sand on the surface of the subframe more thoroughly removed, thus helping to improve the sand-vibrating effect.

[0011] Optionally, a first through hole is provided on the side wall of the two support boxes that are close to each other, and a second through hole is provided on the side wall of the two support boxes that are far from each other. The diameter of the first through hole is smaller than the diameter of the turntable. A plurality of limiting rollers are provided around the turntable along its circumferential direction. The limiting rollers are rotatably connected inside the support box. The drive assembly includes a drive motor mounted on the base frame, a drive sprocket mounted on the motor shaft of the drive motor, and a chain. A guide rail arranged in a ring is fixedly connected to the turntable near the drive motor. The chain is wrapped around the outer circumference of the guide rail, and both ends of the chain are fixedly connected to the turntable. The drive sprocket meshes with the chain.

[0012] By adopting the above technical solution, the turntable is limited by the cooperation of the support box and several limiting rollers, so that the turntable can only rotate along its own axis. When the drive motor drives the drive sprocket to rotate, the chain drives the turntable to rotate.

[0013] Optionally, each of the supporting beams has two parallel mounting plates at both ends. The mounting plates are arranged parallel to the connecting steel plates. One of the mounting plates is connected to the supporting beam. Several connecting columns are fixedly arranged between the two mounting plates. The end of the connecting steel plate is located between the two mounting plates. Several elastic columns are arranged between the connecting steel plate and each mounting plate.

[0014] By adopting the above technical solution, the two ends of the connecting steel plate are connected to the mounting plate by elastic columns, thereby realizing the elastic connection between the vibrating frame and the support frame, increasing the vibration amplitude of the connecting steel plate, making it easier to vibrate the molding sand, and improving the efficiency of sand vibration.

[0015] Optionally, the base plate is provided with protrusions near the connecting steel plate, the protrusions are arranged parallel to the connecting steel plate, and the protrusions are connected to the center position of the connecting steel plate in the length direction.

[0016] By adopting the above technical solution, the base plate and the connecting steel plate are connected at the center along the length direction, thereby increasing the amplitude of the elastic deformation of the connecting steel plate itself, which in turn increases the vibration amplitude of the vibrating frame and improves the effect of sand vibration.

[0017] Optionally, two of the support beams are disposed opposite each other at the bottom of the base plate, and a plurality of support brackets are disposed between the two support beams, each of the support brackets being provided with a support air cushion.

[0018] By adopting the above technical solution, the support air cushion provides elastic support to the center of the base plate, thereby making the base plate more stable and reducing the possibility of deformation.

[0019] Optionally, the hammering mechanism includes a rotating shaft rotatably disposed between the two support housings, a hammering frame connected to the rotating shaft, a hammering mounting beam disposed on the hammering frame, and a plurality of hammering components disposed on the hammering mounting beam. The rotating shaft is horizontally disposed, the plurality of hammering mounting beams are disposed along the length direction of the rotating shaft, the length direction of the hammering mounting beams is perpendicular to the axis of the rotating shaft, and a plurality of hammering components are disposed on each of the hammering mounting beams. The hammering components are used to hammer the striking block.

[0020] By adopting the above technical solution, the entire hammering mechanism can be rotated by a rotating shaft mounted on the support box, which facilitates the clamping of the subframe. Several hammering mounting beams are set on the hammering frame, and several hammering components are set on each hammering mounting beam, so that several hammering blocks can be hammered at the same time, which helps to improve the effect of sand vibration.

[0021] Optionally, a drive cylinder is provided on the connecting beam near the top of the support box. The cylinder body of the drive cylinder is hinged to the connecting beam. A V-shaped plate is connected to the rotating shaft. The piston rod of the drive cylinder is hinged to the end of the V-shaped plate away from the rotating shaft.

[0022] By adopting the above technical solution, when the piston rod of the drive cylinder extends or retracts, it drives the V-shaped plate to rotate, thereby realizing the rotation of the shaft.

[0023] Optionally, each of the hammering components includes a mounting base disposed on the hammering mounting beam and a pneumatic hammer body detachably connected to the mounting base. The mounting base is perpendicular to the rotating shaft. A locking plate is disposed on one side of the mounting base. The hammering mounting beam is located between the mounting base and the locking plate. A T-shaped groove is formed on the mounting base along its length. Two locking bolts are disposed inside the T-shaped groove along its length. The heads of the locking bolts are located inside the T-shaped groove. The screws of the locking bolts rotate through the locking plate and are connected to a locking nut. The locking nut abuts against the locking plate.

[0024] By adopting the above technical solution, the locking plate is connected to the mounting base by locking bolts and locking nuts. Loosening the locking nuts not only allows the mounting base to slide along the length of the mounting beam, increasing the adjustable range of the hammering assembly, but also allows the head of the locking bolt to slide inside the T-slot, allowing the mounting base to move along the width of the mounting beam to match hammering blocks of different heights, ultimately greatly improving the applicability of a single hammering assembly.

[0025] Optionally, the air hammer body is provided with a fixing plate, and the mounting base, except for the side with the T-shaped groove, has several threaded holes along its length on the other side walls. The fixing plate is detachably connected to the mounting base by bolts.

[0026] By adopting the above technical solution, the air hammer body can be installed in different positions on the mounting base as needed, which facilitates matching with the striking block and thus improves the adaptability of the hammering component.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. The cast subframe is placed entirely on the vibrating frame. The subframe is positioned by the insertion and engagement of the positioning head and the mounting ring. Then, a hammering mechanism strikes the striking blocks on the subframe, causing the molding sand to crack and detach. The vibrating motor then operates. Due to the elastic connection between the two ends of the connecting steel plate and the end of the support beam, not only can the steel plate itself move significantly, but its deformation also increases the vibration amplitude, allowing the entire vibrating frame to vibrate dramatically. This ensures more thorough detachment of the molding sand from the subframe, improving the efficiency of sand vibration. After sand vibration is complete, all striking blocks are divided, effectively protecting the subframe body. 2. The two ends of the connecting steel plate are connected to the mounting plate by elastic columns, thereby realizing the elastic connection between the vibrating frame and the support frame, increasing the vibration amplitude of the connecting steel plate, making it easier to vibrate the molding sand, and improving the efficiency of sand vibration. 3. Connect the locking plate to the mounting base using locking bolts and locking nuts. Loosening the locking nuts allows the mounting base to slide along the length of the mounting beam, increasing the adjustable range of the hammering assembly. At the same time, the head of the locking bolt can slide inside the T-slot, allowing the mounting base to move along the width of the mounting beam to match hammering blocks of different heights, ultimately greatly improving the applicability of a single hammering assembly.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 2-8 This application will be described in further detail.

[0038] This application discloses a casting vibratory sand machine for subframes.

[0039] Reference Figure 2 and Figure 3 A casting sand vibrating machine for subframes includes a base frame 1, a tilting mechanism 5, a support frame 2, a vibrating frame 3, and a hammering mechanism 4. The tilting mechanism 5 is mounted on the base frame 1, the support frame 2 is mounted on the tilting mechanism 5, the vibrating frame 3 is mounted on the base frame 1, and the hammering mechanism 4 is mounted on the base frame 1. The subframe is placed on the vibrating frame 3, and the hammering mechanism 4 hammers the striking blocks 05 on the subframe, causing the molding sand covering the subframe to crack. After hammering, the vibrating frame 3 vibrates, and simultaneously the tilting mechanism 5 tilts the subframe, thereby causing the molding sand on the subframe to completely fall off.

[0040] Reference Figure 2The base frame 1 includes a support box 11 and a connecting beam 12. The support box 11 is vertically arranged, and there are two support boxes 11 arranged vertically at intervals. The connecting beam 12 is horizontally arranged between the two support boxes 11. The two ends of the connecting beam 12 are welded to the support box 11. In this embodiment, there are three connecting beams 12, two of which are distributed at two corners of the bottom of the support box 11, and the other is near one corner of the top of the support box 11, so that the base frame 1 has an opening for easy placement of the subframe. When in use, the base frame 1 is placed directly on the conveyor belt, and the falling molding sand falls onto the conveyor belt through the gap between the two connecting beams 12.

[0041] Reference Figure 2 and Figure 4 The flipping mechanism 5 includes a turntable 51 and a drive assembly 52. ​​Each of the two support housings 11 has a first through hole 111 on its adjacent sidewalls and a second through hole 112 on its distant sidewalls. The axis of the first through holes 111 is horizontal, and all the first through holes 111 and all the second through holes 112 are coaxially arranged. The diameter of the first through hole 111 is smaller than the diameter of the second through hole 112. One turntable 51 is provided inside each support housing 11. The diameter of the first through hole 111 is smaller than the diameter of the turntable 51, and the turntable 51 is coaxially arranged with the first through hole 111. Several limiting rollers 113 are provided inside each support box 11. The limiting rollers 113 are distributed along the circumference of the turntable 51. The limiting rollers 113 are rotatably connected to the support box 11. The edge of the turntable 51 abuts against the limiting rollers 113. The limiting rollers 113 limit the turntable 51 so that the turntable 51 can only rotate on its own.

[0042] Reference Figure 2 and Figure 4 The drive assembly 52 includes a drive motor 521, a drive sprocket 522, and a chain 523. The drive motor 521 is fixedly mounted on the support housing 11. The drive sprocket 522 is coaxially fixedly connected to the motor shaft of the drive motor 521. A ring-shaped guide rail 511 is fixedly connected to a turntable 51 near the drive motor 521. The chain 523 is wound around the outer circumference of the guide rail 511, and both ends of the chain 523 are fixedly connected to the turntable 51. The drive sprocket 522 meshes with the chain 523. Two guide sprockets 512 are rotatably mounted inside the support housing 11. The guide sprockets 512 are located between the turntable 51 and the drive sprocket 522. The side of the two guide sprockets 512 that is close to each other meshes with the chain 523, thereby guiding and limiting the chain 523.

[0043] Reference Figure 2 and Figure 4The support frame 2 is bolted between the two turntables 51. When the drive motor 521 is working, the drive sprocket 522 and chain 523 drive the turntables 51 to rotate, thereby causing the entire support frame 2 and the subframe to flip.

[0044] Reference Figure 2 and Figure 5 The support frame 2 includes support beams 21 and connecting plates 22. Several support beams 21 are horizontally arranged between the two support boxes 11. In this embodiment, three support beams 21 are provided, two of which are arranged opposite each other at the bottom of the vibration frame 3, and the other is located above one of the support beams 21 at the bottom of the vibration frame 3. Alternatively, only two support beams 21 can be provided at the bottom of the vibration frame 3. Connecting plates 22 are welded to both ends of each support beam 21. The connecting plates 22 are arranged parallel to the surface of the turntable 51 and are detachably connected to the turntable 51 by bolts.

[0045] Reference Figure 2 , Figure 5 and Figure 6 Two mounting plates 211 are provided on each support beam 21. The mounting plates 211 are located on the side of the two support beams 21 that are far apart from each other. The two mounting plates 211 are arranged in parallel and perpendicular to the surface of the turntable 51. Several connecting columns 212 are fixedly connected between the two mounting plates 211. This embodiment takes four as an example, and one of the mounting plates 211 is fixedly connected to the support beam 21.

[0046] Reference Figure 2 , Figure 5 and Figure 6 The vibrating frame 3 includes a connecting steel plate 31, a base plate 32, a positioning head 33, and a vibrating motor 34. One connecting steel plate 31 is provided on one side of each support beam 21. The connecting steel plates 31 are perpendicular to the surface of the turntable 51. Both ends of each connecting steel plate 31 are located between two mounting plates 211. Several elastic columns 213 are fixedly installed between each mounting plate 211 and the connecting steel plate 31. This embodiment uses two as an example. The base plate 32 is located on two opposing support beams 21. A protrusion 321 is fixedly installed on the base plate 32 near each connecting steel plate 31. The protrusion 321 is parallel to the connecting steel plate 31, and the protrusion 321 is bolted to the center of the connecting steel plate 31 along its length.

[0047] Reference Figure 3 , Figure 5 and Figure 6A positioning frame 322 is fixedly mounted on the base plate 32. Several positioning heads 33 are mounted on the positioning frame 322. In this embodiment, four are used as an example. Each positioning head 33 is used to insert and mate with a single mounting ring 03. Each positioning head 33 includes a base plate 331 bolted to the positioning frame 322 and a positioning post 332 fixedly mounted on the base plate 331. Each positioning post 332 has a stepped surface at its top, which can be freely selected according to the diameter of the mounting ring 03. Two vibration motors 34 are fixedly mounted on the side of the base plate 32 near the support beam 21 above it.

[0048] Reference Figure 3 , Figure 5 and Figure 6 The entire subframe is placed on the vibration frame 3, and the subframe is positioned by inserting the positioning head 33 into the mounting ring 03. The base plate 32 is connected to the center of the connecting steel plate 31 along its length by the protrusion 321, and both ends of the connecting steel plate 31 are elastically connected to the ends of the support beam 21. When the vibration motor 34 is working, not only can the connecting steel plate 31 move significantly as a whole, but the connecting steel plate 31 itself can also undergo significant deformation, thereby enabling the vibration frame 3 to vibrate significantly and improve the sand-vibrating effect.

[0049] Reference Figure 5 In order to provide elastic support for the middle position of the base plate 32, several support frames 23 are provided below the base plate 32. In this embodiment, two support frames are used as an example. The support frames 23 are fixedly connected to the support beam 21. Each support frame 23 is provided with a support air cushion 231. The support air cushion 231 abuts against the bottom of the base plate 32, and the support air cushion 231 provides elastic support for the base plate 32.

[0050] Reference Figure 3 and Figure 7 The hammering mechanism 4 includes a rotating shaft 41, a hammering frame 42, a hammering mounting beam 43, and a hammering assembly 44. The rotating shaft 41 is rotatably mounted between two support housings 11, and is horizontally positioned. The rotating shaft 41 is located near the connecting beam 12 at the top of the support housing 11. A drive cylinder 411 is mounted on the connecting beam 12 near the top of the support housing 11. The cylinder body of the drive cylinder 411 is hinged to the connecting beam 12. A V-shaped plate 412 is fixedly connected to the rotating shaft 41, and the piston rod of the drive cylinder 411 is hinged to the end of the V-shaped plate 412 away from the rotating shaft 41. The extension and retraction of the piston rod of the drive cylinder 411 drives the rotating shaft 41 to rotate.

[0051] Reference Figure 7 and Figure 8The hammering frame 42 is fixedly connected to the rotating shaft 41. Several hammering mounting beams 43 are arranged on the hammering frame 42 along the axis of the rotating shaft 41. In this embodiment, four are used as an example. The hammering mounting beams 43 are located in a vertical plane, and their length direction is perpendicular to the axis of the rotating shaft 41. Each hammering mounting beam 43 has two locking blocks 431 at one end near the hammering frame 42. The two locking blocks 431 are distributed on both sides of the length direction of the hammering mounting beam 43. Each locking block 431 is connected to the hammering mounting beam 43 by bolts. The side of the two locking blocks 431 that are close to each other is pressed against the hammering frame 42, thereby realizing the positioning of the hammering mounting beam 43. The number and installation position of the hammering mounting beams 43 can be adjusted.

[0052] Reference Figure 7 and Figure 8 Several hammer-bearing components 44 are provided on each hammer-bearing mounting beam 43. In this embodiment, two are used as an example. Each hammer-bearing component 44 includes a mounting base 441 and a pneumatic hammer body 442. The mounting base 441 is arranged perpendicularly to the rotating shaft 41. A locking plate 4412 is provided on one side of each mounting base 441. The hammer-bearing mounting beam 43 is located between the mounting base 441 and the locking plate 4412. A T-shaped groove 4411 is formed on each mounting base 441 along its length direction. Two locking bolts 4413 are arranged along the length of the mounting base 4411. The head of the locking bolt 4413 is located inside the T-slot 4411, and the thread of the locking bolt 4413 extends out of the T-slot 4411. The hammer mounting beam 43 is located between the two locking bolts 4413. The thread of the locking bolt 4413 rotates through the locking plate 4412. Each locking bolt 4413 has a locking nut 4414 connected to its thread, and the locking nut 4414 abuts against the locking plate 4412. The locking bolts 4413 and the locking nuts 4414 cooperate to position the mounting base 441, which facilitates the adjustment of the number and position of the hammering components 44 on a single hammer mounting beam 43.

[0053] Reference Figure 7 and Figure 8 The mounting base 441 is a cuboid. Except for one side with a T-slot 4411, each of the other three side walls of the mounting base 441 has several threaded holes 4415 along its length. A fixing plate 4421 is fixedly mounted on each air hammer body 442, and the fixing plate 4421 is detachably connected to the mounting base 441 by bolts. Connecting the air hammer bodies 442 to the mounting base 441 by bolts allows for easy repositioning of each air hammer body 442 as needed.

[0054] Reference Figure 3 , Figure 7 and Figure 8After the subframe is positioned, the drive cylinder 411 drives the rotating shaft 41 to rotate, so that several hammering components 44 are located above the subframe. At this time, the hammering components 44 are distributed in several groups along the length of the rotating shaft 41. Each group is distributed in the horizontal direction, and the position of each hammering component 44 can be adjusted in the horizontal plane. At the same time, the height of each mounting base 441 can also be adjusted to accommodate the striking blocks 05 at various positions. Each air hammer body 442 corresponds to one striking block 05. The air hammer body 442 directly strikes the striking block 05 to perform sand vibration operation.

[0055] The implementation principle of a casting vibrating sand machine for a subframe according to an embodiment of this application is as follows: The cast subframe is placed on a vibrating frame 3, and the positioning head 33 is inserted and engaged with the mounting ring 03 to position the subframe. Then, the drive cylinder 411 drives the rotating shaft 41 to rotate, so that several hammering components 44 are positioned directly above the subframe. The hammering components 44 simultaneously hammer several striking blocks 05, causing the molding sand on the subframe to crack and fall off. After hammering, the vibrating motor 34 operates, causing the entire vibrating frame 3 to vibrate significantly. At the same time, the two turntables 51 drive the vibrating frame 3 to rotate, thereby making the molding sand on the subframe more thoroughly detached and improving the efficiency of sand vibration. After sand vibration is completed, all striking blocks 05 are divided.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
