Description

Technical Field

[0001] This utility model belongs to the field of aluminum casting straightening technology, and in particular relates to a straightening tooling for aluminum casting processing. Background Technology

[0002] Aluminum castings are produced by melting aluminum alloys or pure aluminum at high temperatures, pouring the melted material into a mold, and then allowing it to cool and solidify. Aluminum castings possess excellent corrosion resistance, light weight, and superior mechanical properties, making them widely used in various industries.

[0003] According to the search, the application (publication) number: CN202322877228.6 discloses: an aluminum casting straightening fixture, which "includes an operating table, an installation mechanism and a clamping mechanism, and a mechanical arm is fixedly connected to the upper surface of the operating table", and has technical effects such as "facilitating the limiting of aluminum castings and facilitating the replacement of brush heads".

[0004] In actual use, it was found that although the "clamping mechanism" can achieve the adjustment purpose, it does not clamp the aluminum casting in all four directions of the horizontal plane. This causes the aluminum casting to shift when the robotic arm moves and grinds. In addition, some aluminum castings are thin, and relying on the clamping pressure to position them may cause deformation of the clamping position and produce indentations.

[0005] To address the aforementioned issues, this application proposes a straightening fixture for machining aluminum castings. Utility Model Content

[0006] The purpose of this utility model is to provide a straightening fixture for processing aluminum castings, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a straightening fixture for aluminum casting processing, comprising a support platform. Two opposing first and second positioning plates are respectively provided on the support platform. The support platform includes an outer casing and a base plate fixed to the bottom inner side of the outer casing. A top plate is fixed to the top inner side of the outer casing. Transmission boxes are fixed on both sides between the base plate and the top plate. An adjusting plate is provided on the support platform, adjustablely connected to the second positioning plate. A first guide rail, inclined relative to the first and second positioning plates, is fixed to the top surface of the base plate. Two movable seats fixed to the first positioning plates are provided inside the support platform. Two third guide rails fixed to the adjusting plate are also provided inside the support platform. A driving component is provided in the support platform to drive the two movable seats to move simultaneously. Transmission columns slide in the first guide rails, movable seats, and third guide rails.

[0009] Furthermore, the movable seat is provided with a second guide rail parallel to the first positioning plate, and the movable seat is slidably connected to the transmission column through the second guide rail. The third guide rail is parallel to the second positioning plate and is perpendicular to the second guide rail.

[0010] Furthermore, the drive component includes two bidirectional lead screws symmetrically arranged in two transmission boxes. One end of the two bidirectional lead screws is linked by a synchronous pulley set, and one end of one of the bidirectional lead screws is fixed with a motor located inside the transmission box.

[0011] Furthermore, the bidirectional lead screw is threadedly connected to the internal thread sleeve on the movable seat, and the spiral of both drives the two movable seats at their upper ends to move inward or outward synchronously.

[0012] Furthermore, a linear guide hole is provided through the movable seat, and a fixed linear guide rod is provided between the two transmission boxes. The linear guide hole is penetrated by the linear guide rod and the two are slidably engaged.

[0013] Furthermore, the second positioning plate is rotatably provided with a screw and a guide rod is fixed thereon, and the adjusting plate is provided with a threaded hole and a guide hole through it.

[0014] Furthermore, the threaded hole is threadedly engaged with the guide hole, and the screw is also provided with a turning wheel, while the guide rod is slidably engaged with the guide hole.

[0015] This utility model has the following beneficial effects:

[0016] This utility model, through the driving of the driving component, can drive the two first positioning plates on the left and right and the two second positioning plates in front and behind to move inward or outward simultaneously. After the aluminum casting is placed on the support platform, the positioning plates tighten and position the aluminum template, but do not apply clamping force, so as to ensure the limiting effect while avoiding indentation on the aluminum casting.

[0017] The second positioning plate and the adjustment plate in this invention are adjustable to accommodate the positioning of aluminum castings of different sizes, providing reliability and flexibility. This invention can drive the aluminum castings to move in four directions (front, back, left, and right) through a single motor, thus enabling convenient, stable, and reliable positioning.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please see Figure 1-4As shown, this utility model is a straightening fixture for aluminum casting processing, including a support platform 1. The support platform 1 is provided with two opposing first positioning plates 2 and second positioning plates 3. The support platform 1 includes an outer cover 11 and a bottom plate 12 fixed to the bottom of the inner side of the outer cover 11. A top plate 13 is fixed to the top of the inner side of the outer cover 11. Transmission boxes 14 are fixed on both sides between the bottom plate 12 and the top plate 13. The support platform 1 is provided with an adjustment plate 4 that is adjustablely connected to the second positioning plate 3. A first guide rail 5 is fixed to the top surface of the bottom plate 12 and is inclined relative to the first positioning plate 2 and the second positioning plate 3. The support platform 1 is provided with two movable seats 6 fixed to the first positioning plate 2. The support platform 1 is also provided with two third guide rails 7 fixed to the adjustment plate 4. The support platform 1 is provided with a driving component 8 that drives the two movable seats 6 to move simultaneously. Transmission columns 9 slide in the first guide rail 5, the movable seats 6 and the third guide rails 7.

[0029] The movable seat 6 has a second guide rail 62 parallel to the first positioning plate 2. The movable seat 6 is slidably connected to the transmission column 9 through the second guide rail 62. The third guide rail 7 is parallel to the second positioning plate 3 and perpendicular to the second guide rail 62. In this embodiment, when the transmission column 9 moves inside the second guide rail 62, the transmission column 9 slides along the first guide rail 5 and drives the third guide rail 7 to move, thereby realizing the linkage when the first positioning plate 2 and the second positioning plate 3 move in different directions.

[0030] The drive component 8 includes two bidirectional lead screws 81 symmetrically arranged in two transmission boxes 14. One end of the two bidirectional lead screws 81 is linked by a synchronous pulley group 82. One end of one of the bidirectional lead screws 81 is fixed with a motor 83 located inside the transmission box 14. In this embodiment, two bidirectional lead screws 81 are arranged and distributed at the end of the movable seat 6, which enhances the movement stability of the movable seat 6 while ensuring the transmission effect.

[0031] The bidirectional lead screw 81 is threadedly connected to the internal threaded sleeve 61 on the movable seat 6, and the two movable seats 6 at their upper ends move inward or outward synchronously through the spiral of the two screws. In this embodiment, the synchronous pulley group 82 drives the two bidirectional lead screws 81 to rotate in the same direction, and the spiral directions on the two bidirectional lead screws 81 are opposite, so that the two movable seats 6 can move inward or outward simultaneously.

[0032] The movable seat 6 is provided with a linear guide hole 63, and a fixed linear guide rod 141 is provided between the two transmission boxes 14. The linear guide hole 63 is penetrated by the linear guide rod 141 and the two slide together. In this embodiment, by setting the cooperation between the linear guide hole 63 and the linear guide rod 141, the stability of the movable seat 6 in the support platform 1 is effectively improved. It also makes the internal thread sleeve 61 and the second guide rail 62 cooperate more smoothly with the bidirectional lead screw 81 and the transmission column 9. Of course, in order to make it smoother, lubricating oil can be applied to its friction contact position.

[0033] The second positioning plate 3 is rotatably equipped with a screw 31 and a guide rod 32 is fixed thereon. The adjusting plate 4 is provided with a threaded hole 41 and a guide hole 42 through it. The threaded hole 41 and the guide hole 42 are threadedly engaged. The screw 31 is also provided with a screw wheel. The guide rod 32 is slidably engaged with the guide hole 42. The adjustment method in this embodiment has a simple structure and high adjustment accuracy. In order to further improve the stability after adjustment, a threaded sleeve can be set on the outside of the screw 31. When the position of the screw 31 and the threaded hole 41 is determined, the threaded sleeve and the screw 31 are pressed together with the threaded hole 41 to achieve a strengthening effect on stability.

[0034] Understandably, a single motor can drive the first and second positioning plates in different directions to move inward or outward simultaneously, thereby achieving omnidirectional positioning of the aluminum casting in the horizontal direction. This ensures the stability and reliability of the aluminum casting during straightening, and the controllability and consistency of the single motor are improved. Furthermore, the second positioning plate can be adjusted independently to adapt to the positioning of aluminum castings of different sizes, offering high flexibility and practicality.

[0035] One specific application of this embodiment is:

[0036] Preparations before continuous straightening: Place the aluminum casting on the top plate 13, and drive the two first positioning plates 2 and the two second positioning plates 3 to move inward simultaneously through the drive component 8 until the aluminum casting of the two first positioning plates 2 is in contact with each other. At this time, the second positioning plates 3 are not in contact with the aluminum casting. By rotating the screw 31 and the screw hole 41, the moving force generated by the screw makes the two second positioning plates 3 also in contact with the aluminum casting. At this time, a restrictive space that matches the aluminum casting is formed between the two first positioning plates 2 and the two second positioning plates 3.

[0037] Correction work: The robotic arm and motor drive the brush head to move and rotate, and perform correction work on the positioned aluminum casting. After the correction work is completed, the drive component 8 works in reverse to drive the two first positioning plates 2 and the two second positioning plates 3 to move outward at the same time, so as to facilitate the removal of the aluminum casting. Then the aluminum casting to be processed is placed again. At this time, the positioning of the aluminum casting can be completed by directly driving the drive component 8, and the grinding work can be carried out directly. The above steps can be repeated continuously.

[0038] The specific structural workflow is as follows: The output of motor 83 drives two bidirectional lead screws 81 to rotate synchronously through synchronous pulley group 82. At this time, under the helical movement force of bidirectional lead screw 81 and internal threaded sleeve 61, the two movable seats 6 are driven to move synchronously in opposite directions. The first positioning plate 2 fixed at the upper end of the movable seat 6 moves synchronously. The movable seat 6 drives the transmission column 9 to move under the action of the second guide rail 62. At this time, the transmission column 9 is still sliding inside the first guide rail 5 and the third guide rail 7. After the transmission column 9 slides, it drives the second positioning plate 3 and the adjusting plate 4 to move synchronously, thereby forming synchronous positioning and release work.
