Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, and in particular to a three-point hydraulic support fixture for preventing casting deformation. Background Technology

[0002] During the machining process of castings, due to their large weight and the external forces such as cutting forces, they are prone to deformation, which affects the machining accuracy and product quality.

[0003] Most existing support clamps adopt rigid support structures, which are difficult to adjust flexibly according to castings of different shapes and sizes, cannot achieve uniform support for castings, and cannot effectively prevent casting deformation. Some support clamps, while possessing certain adjustment functions, have complex structures, are inconvenient to operate, have high costs, and poor practicality. Therefore, this utility model proposes a three-point hydraulic support clamp for preventing casting deformation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a three-point hydraulic support fixture for castings to prevent deformation. By setting three mutually cooperating hydraulic clamping mechanisms, it can clamp and fix castings of different shapes at fixed points to avoid deformation and ensure the firmness of the castings during processing. Furthermore, a receiving component is set at the bottom of the casting to adjust and fix the bottom position of the casting, and together with the hydraulic clamping mechanisms, clamp and fix the casting at the appropriate outer wall position.

[0005] To solve the above-mentioned technical problems, the present invention provides a three-point hydraulic support fixture for casting anti-deformation, including a support ring frame, wherein the inner wall of the support ring frame is smoothly fitted with an adjustment component to fix the casting in the vertical direction.

[0006] The top of the support ring frame is fixedly connected to a mounting plate. The outer wall of the mounting plate is evenly provided with three protrusions, and a hydraulic clamping mechanism is bolted to each of the three protrusions. The casting is clamped and fixed by the three hydraulic clamping mechanisms.

[0007] The present invention is further configured such that: the outer wall of the support ring frame is uniformly fixedly connected with mounting corner blocks in the circumferential direction near the bottom position.

[0008] The above technical solution allows for the installation and fixation of the support ring frame using multiple mounting corner blocks.

[0009] The present invention is further configured such that: the hydraulic clamping mechanism includes a hydraulic cylinder bolted to the top of the mounting plate, a clamping block is fixedly connected to the end face of the drive rod of the hydraulic cylinder, and multiple anti-slip strips and anti-slip balls are evenly fixedly connected to the side wall of the clamping block.

[0010] By using the above technical solution, the hydraulic cylinder is activated, and its drive rod moves the clamping block on the end face, thereby allowing the anti-slip strip and anti-slip ball on the end face to clamp and fix the outer wall of castings of different shapes, thus achieving three-point positioning and fixing.

[0011] The present invention is further configured such that the clamping block is V-shaped as a whole, and multiple anti-slip balls are located on the two inner sidewalls of the V-groove.

[0012] The above technical solution facilitates the clamping of castings of different shapes, using V-grooves for clamping and anti-slip balls for protective clamping and fixing, thus avoiding damage to the outer wall of the casting.

[0013] The present invention is further configured such that the plurality of anti-slip strips are arranged in two groups and are respectively located at the two protruding positions of the V-shaped clamping block.

[0014] The above technical solution facilitates the use of anti-slip strips to clamp and fix the outer wall of castings of different shapes in an anti-slip manner, preventing them from shaking and falling off.

[0015] The present invention is further configured such that: the adjustment assembly includes an adjustment plate, the outer wall of the adjustment plate is uniformly and fixedly connected with a plurality of sliding connecting parts, each of the plurality of sliding connecting parts is slidably connected with a slide rod, and the plurality of slide rods are respectively installed inside the movable groove opened in the circumferential direction of the support ring frame, and the outer wall of each of the plurality of slide rods is sleeved with a spring.

[0016] The above technical solution involves placing the casting onto the adjusting plate, using its own weight to make the adjusting plate slide on the slide rod through the sliding connection, compressing the spring, and using the spring's restoring elasticity to make the adjusting plate tend to be stable. At the same time, a hydraulic clamping mechanism is used to clamp and fix the casting.

[0017] The present invention is further configured such that: multiple through holes are equidistantly opened in the circumferential direction on the adjustment plate, and the two ends of the multiple springs respectively abut against the inner bottom of the movable groove and the bottom of the sliding connection.

[0018] The above technical solution utilizes multiple through holes to reduce the weight of the adjustment plate, while multiple springs can drive the adjustment plate to reset its position via a sliding connection, thereby achieving clamping and fixing adjustment of the casting at different positions.

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

[0028] 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.

[0029] like Figures 1-4As shown, a three-point hydraulic support fixture for casting deformation prevention includes a support ring frame 1. Mounting corner blocks 11 are evenly fixedly connected circumferentially to the outer wall of the support ring frame 1 near its bottom position. Multiple mounting corner blocks 11 can fix the position of the support ring frame 1. An adjustment component 4 is smoothly fitted to the inner wall of the support ring frame 1 to fix the casting in a vertical position. The adjustment component 4 includes an adjustment plate 41 with multiple through holes 42 evenly spaced circumferentially. These through holes 42 can reduce the weight of the adjustment plate 41. Multiple sliding connecting parts 43 are evenly fixedly connected to the outer wall of the adjustment plate 41. Each sliding connecting part 43 is slidably connected to a sliding rod 44. Rods 44 are respectively installed inside the movable slots 12 opened in the circumferential direction of the support ring frame 1. Springs 45 are sleeved on the outer walls of multiple sliding rods 44. When the casting is placed on the adjusting plate 41, its own weight causes the adjusting plate 41 to slide on the sliding rods 44 through the sliding connection part 43, compressing the springs 45. The restoring elasticity of the springs 45 stabilizes the adjusting plate 41. Simultaneously, a hydraulic clamping mechanism 3 clamps and fixes the casting. The two ends of the multiple springs 45 are respectively pressed against the inner bottom of the movable slot 12 and the bottom of the sliding connection part 43. The multiple springs 45 can drive the adjusting plate 41 to perform positional adjustment through the sliding connection part 43, thus achieving clamping and fixing adjustment of the casting at different positions.

[0030] like Figure 2 and Figure 3 As shown, a mounting plate 2 is fixedly connected to the top of the support ring frame 1. Three protrusions are evenly distributed on the outer wall of the mounting plate 2, and hydraulic clamping mechanisms 3 are bolted to each of the three protrusions. The casting is clamped and fixed by the three hydraulic clamping mechanisms 3. Each hydraulic clamping mechanism 3 includes a hydraulic cylinder 31 bolted to the top of the mounting plate 2. A clamping block 32 is fixedly connected to the end face of the drive rod of the hydraulic cylinder 31. Multiple anti-slip strips 33 and anti-slip balls 34 are evenly fixedly connected to the side wall of the clamping block 32. When the hydraulic cylinder 31 is activated, its drive rod moves the clamping block 32 on its end face, thereby causing the anti-slip strips on the end face to... The clamping blocks 33 and anti-slip balls 34 clamp and fix the outer walls of castings of different shapes, thereby achieving three-point positioning and fixing. The clamping block 32 is V-shaped, and multiple anti-slip balls 34 are located on the two inner side walls of the V-groove, which facilitates clamping the outer walls of castings of different shapes. The V-groove is used for clamping, and the anti-slip balls 34 are used for protective clamping and fixing to avoid damage to the outer walls of the castings. Multiple anti-slip strips 33 are set in two groups and are located on the two protruding positions of the V-shaped clamping block 32, which facilitates anti-slip clamping and fixing of the outer walls of castings of different shapes using the anti-slip strips 33 to prevent shaking and falling off.

[0031] In use, the casting is first placed on the adjusting plate 41 inside the support ring frame 1. Its own weight causes the adjusting plate 41 to slide on the slide rod 44 through the sliding connection part 43, and compresses the spring 45. The spring 45's return elasticity makes the adjusting plate 41 tend to be stable. The pressure or lifting is adjusted according to the clamping position. At the same time, the hydraulic cylinder 31 is activated, and its drive rod drives the clamping block 32 on the end face to move, so that the anti-slip strip 33 and anti-slip ball 34 on the end face clamp and fix the outer wall of the casting of different shapes, thereby achieving three-point positioning and fixing.
