Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, and in particular to a multi-directional support fixture for preventing deformation of thin-walled castings. Background Technology

[0002] In the modern casting industry, with the continuous improvement of product performance requirements, thin-walled castings have been widely used in various fields due to their advantages such as light weight, high material utilization, and compact structure. However, thin-walled castings have thin walls and complex structures. During the processing, factors such as cutting forces and thermal stress generated during machining, as well as gravity and external collisions during handling and storage, can easily cause them to deform. Once a thin-walled casting deforms, it will not only cause its dimensional accuracy to fail to meet design requirements, affecting subsequent assembly and use, but may also lead to the scrapping of the casting, resulting in resource waste and increased costs.

[0003] Currently, most existing support fixtures on the market have relatively simple structures, typically only supporting thin-walled castings from a single direction, and cannot effectively limit deformation of thin-walled castings in multiple directions. Furthermore, these fixtures often lack adjustment capabilities, making them difficult to adapt to thin-walled castings of different specifications, shapes, and sizes, resulting in poor versatility. In addition, the contact points between traditional support fixtures and thin-walled castings are prone to scratches, indentations, and other damage to the casting surface during the support process due to the hardness of the material or the lack of smoothness, further reducing the quality and yield of the castings. Therefore, this utility model proposes a multi-directional support fixture for preventing deformation of thin-walled castings. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a multi-directional support fixture for preventing deformation of thin-walled castings. Through innovative design of the fixture structure, it solves the problems of existing support fixtures being unable to provide multi-directional support, having poor versatility, and being prone to damaging the surface of castings. It achieves all-round effective support for thin-walled castings, ensuring that thin-walled castings maintain stable shape and dimensional accuracy during processing, handling, and storage, thereby improving the quality of castings and production efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a multi-directional support fixture for preventing deformation of thin-walled castings is provided, including a base, a support seat and a drive mechanism are bolted to the top center of the base, the support seat is wrapped around the drive mechanism, and the top of the drive mechanism passes through the top of the support seat.

[0006] The top circumference of the support base is uniformly slidably connected with multiple positioning components, one end of each positioning component is slidably connected to the top of the drive mechanism, and the other end is pressed against the inner wall of the casting body.

[0007] The present invention is further provided that: an anti-slip rubber pad is adhered to the bottom of the base.

[0008] The above technical solution uses anti-slip rubber pads to stabilize the base after placement, preventing shaking during processing.

[0009] The present invention is further configured such that: the support base includes multiple Z-shaped frames, the top of the multiple Z-shaped frames is bolted to a support plate, the top of the support plate is evenly provided with multiple sliding grooves in the circumferential direction, and multiple positioning components are slidably connected to the inside of the sliding grooves respectively, and the bottom of the multiple sliding grooves is provided with a sluice.

[0010] The above technical solution allows multiple Z-shaped frames to support the entire tooling, while facilitating the installation of internal structural components. Additionally, the grooves inside the slide allow for easy cleaning of debris trapped inside the slide after processing.

[0011] The present invention is further configured such that: the positioning component includes a slide bar slidably connected inside the slide groove, a connecting rod is threadedly connected to the end face of the slide bar, a limiting shaft is fixedly connected to the end face of the connecting rod, a roller is symmetrically rotatably connected to the end face of the limiting shaft, the limiting shaft is rotatably connected to the top of the drive mechanism through the roller, a buffer component is provided at the top of the slide bar near the middle position, and a positioning block is bolted to the top of the buffer component.

[0012] The above technical solution facilitates the movement of the slider on the connecting rod by using the limiting shaft, which can slide stably inside the slide groove, thereby ensuring stable support and fixation of the casting body. Furthermore, under the action of the rollers, the limiting shaft can be smoothly pushed when the platform is raised or lowered.

[0013] The present invention is further configured such that: the buffer assembly includes two slide rods, the outer walls of the two slide rods are wrapped with springs and slidably connected to sliders, and the sliders are pressed against the end face of the springs.

[0014] The above technical solution facilitates the use of a top positioning block to slide on a sliding rod via a slider when the casting body is pressed and supported, thereby compressing the spring and using the elasticity of the spring to achieve compression buffering and improve the protection of the casting body.

[0015] The present invention is further configured such that: the positioning block is L-shaped, and the vertical sidewall is symmetrically provided with protective strips that abut against the inner wall of the casting body at a position away from the center.

[0016] The above technical solution facilitates the use of protective strips to compress and protect the inner wall of the casting body when the positioning block is driven, thus preventing compression damage.

[0017] The present invention is further configured such that: the driving mechanism includes a driving motor installed on the top of the base, a lead screw is fixedly connected to the end face of the driving shaft of the driving motor, a threaded sleeve is threadedly connected to the outer wall of the lead screw, the inner wall of the threaded sleeve is rotatably connected to the platform near the top, and a plurality of limiting grooves are evenly opened on the outer wall of the platform, and the limiting shaft is rotatably connected to the inner wall of the limiting groove through rollers.

[0018] With the above technical solution, the drive motor is started, and its output shaft drives the lead screw on the end face to rotate, thereby causing the threaded sleeve connected to the outer wall to rise and fall, which in turn causes the top platform to rise and fall. Furthermore, the limiting groove on its outer wall drives the connecting rod and slide bar connected to the limiting shaft to move laterally, thereby enabling the external casting body to be pressed, supported and fixed.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. The multi-directional support fixture for preventing deformation of thin-walled castings proposed in this utility model has positioning components in multiple directions on the support plate, which can simultaneously clamp and fix the inner wall of castings of different sizes, thereby effectively limiting the deformation trend of thin-walled castings in various directions.

[0021] 2. The multi-directional support fixture for preventing deformation of thin-walled castings proposed in this utility model further adds a buffer structure inside the positioning component, so that the positioning component can be buffered to a certain extent when it applies pressure to the thin-walled casting, preventing damage to the casting after being squeezed to a certain extent.

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0030] like Figures 1-5 As shown, a multi-directional support fixture for preventing deformation of thin-walled castings includes a base 1. An anti-slip rubber pad 11 is adhered to the bottom of the base 1, stabilizing the base 1 after placement and preventing shaking during processing. A support seat 2 and a drive mechanism 3 are bolted to the top center of the base 1. The support seat 2 includes multiple Z-shaped frames 21, with a support plate 22 bolted to the top of each Z-shaped frame 21. Multiple grooves 23 are evenly distributed around the top circumference of the support plate 22, and multiple positioning components 4 are slidably connected to the inside of each groove 23. A drainage groove 24 is provided at the bottom of each groove 23. The multiple Z-shaped frames 21 support the entire fixture and facilitate the installation of internal structural components. The drainage grooves 24 inside the grooves 23 facilitate the cleaning of debris trapped inside after processing. The support seat 2 encloses the drive mechanism 3, and the top of the drive mechanism 3 penetrates the top of the support seat 2.

[0031] like Figure 2 and Figure 4As shown, the drive mechanism 3 includes a drive motor 31 mounted on the top of the base 1. A lead screw 32 is fixedly connected to the end face of the drive shaft of the drive motor 31. A threaded sleeve 33 is threadedly connected to the outer wall of the lead screw 32. The inner wall of the threaded sleeve 33 is rotatably connected to the platform 34 near the top. Multiple limiting grooves 35 are evenly opened on the outer wall of the platform 34. The limiting shaft 43 is rotatably connected to the inner wall of the limiting groove 35 through a roller 44. When the drive motor 31 is started, its output shaft drives the lead screw 32 on the end face to rotate, thereby causing the threaded sleeve 33 threadedly connected to the outer wall to rise and fall, thereby causing the platform 34 at the top to rise and fall. The limiting grooves 35 on its outer wall drive the connecting rod 42 and the slide bar 41 connected to the limiting shaft 43 to move laterally, thereby providing a tight support and fixation for the external casting body 5.

[0032] like Figure 5 and Figure 6 As shown, multiple positioning components 4 are slidably connected to the top circumference of the support base 2. One end of each positioning component 4 is slidably connected to the top of the drive mechanism 3, and the other end is pressed against the inner wall of the casting body 5. The positioning component 4 includes a slide bar 41 slidably connected to the inside of the slide groove 23. The end face of the slide bar 41 is threadedly connected to a connecting rod 42. The end face of the connecting rod 42 is fixedly connected to a limiting shaft 43. The end face of the limiting shaft 43 is symmetrically rotatably connected to a roller 44. The limiting shaft 43 is slidably connected to the top of the drive mechanism 3 through the roller 44. This allows the slide bar 41 on the connecting rod 42 to move using the limiting shaft 43, so that it can slide stably inside the slide groove 23, thereby ensuring stable support and fixation of the casting body 5. Furthermore, under the action of the roller 44, the limiting shaft 43 can be smoothly pushed when the platform 34 is raised and lowered.

[0033] like Figure 6 As shown, a buffer assembly 45 is provided at the top of the slide bar 41 near the middle. The buffer assembly 45 includes two slide rods 451. The outer walls of the two slide rods 451 are wrapped with springs 452 and slidably connected to sliders 453. The sliders 453 abut against the end face of the springs 452. When the casting body 5 is pressed and supported, the top positioning block 46 can slide on the slide rods 451 through the sliders 453 and press against the springs 452. The elasticity of the springs 452 is used to achieve compression buffering and improve the protection of the casting body 5. The top of the buffer assembly 45 is bolted to the positioning block 46. The positioning block 46 is L-shaped, and the vertical side wall is symmetrically provided with protective strips 461 that abut against the inner wall of the casting body 5 away from the middle. When the positioning block 46 is driven, it can press against the inner wall of the casting body 5 through the protective strips 461 to prevent compression damage.

[0034] In use, the ladder platform 34 is initially positioned at the bottom. The casting body 5, which needs to be supported and fixed, is then placed on the support plate 22, and multiple positioning components 4 are enclosed inside. The drive motor 31 is then started, and its output shaft drives the lead screw 32 on the end face to rotate, thereby causing the threaded sleeve 33 connected to the outer wall to rise and fall. This causes the top ladder platform 34 to rise and fall. The limiting groove 35 on its outer wall drives the connecting rod 42 and the slide bar 41 connected to the limiting shaft 43 to move laterally. The positioning block 46 on the slide bar 41 presses against the inner wall of the casting body 5 through its protective strip 461. The spring 452 provides a buffering effect during the pressing, thus slowly applying pressure and allowing the positioning components 4 to support and fix the external casting body 5.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
