Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical processing application technology, and in particular to an adaptive flexible clamping milling platform for large castings. Background Technology
[0002] Large castings occupy a key position in high-end equipment manufacturing fields such as aerospace, energy and power, and heavy machinery. Their processing quality directly affects the performance and reliability of the equipment. As industrial manufacturing develops towards higher precision and complexity, the demand for milling of large castings is increasing, which puts forward higher requirements for the precision, stability and adaptability of processing equipment.
[0003] In the milling process of large castings, due to their large size, heavy weight, and irregular shape, traditional fixed clamping methods are difficult to adapt to different shapes and sizes of castings, which can easily lead to unstable clamping, displacement of the casting during milling, affecting machining accuracy, and even causing safety accidents. At the same time, traditional clamping methods cannot automatically adjust the clamping force according to the stress on the casting, which may damage the surface of the casting and reduce the quality of the finished product. Therefore, this utility model proposes an adaptive flexible clamping milling platform for large castings. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an adaptive flexible clamping milling platform for large castings. The platform has a receiving component in the middle to fix the bottom of the placed casting, and the height can be adjusted according to the size of the casting to improve its stability during the milling process. Clamping mechanisms are provided on both sides of the milling platform, which can clamp the casting with anti-slip through the internal flexible clamping blocks. In addition, multiple pressure sensors are provided to adaptively clamp and fix the casting according to the changes in clamping force.
[0005] To solve the above-mentioned technical problems, the present invention provides a technical solution: a large casting adaptive flexible clamping milling platform, including a base, and a support frame fixedly connected to the top of the base, the support frame being an H-shaped structure; The top of the support frame is bolted to a receiving component, and the top of the support frame is provided with a clamping mechanism to flexibly clamp and fix the casting.
[0006] The present invention is further configured such that: mounting grooves are symmetrically provided on the top of the base near the end face.
[0007] The above technical solution facilitates the use of bolts to fix the position of the base using the mounting slot.
[0008] The present invention is further configured such that: the receiving component includes a receiving plate, and adjusting screws are symmetrically fixedly connected to the bottom of the receiving plate near the end face; two adjusting screws respectively penetrate the top of the support frame; a fixing nut is threadedly connected to the outer wall of each of the two adjusting screws, and the fixing nut is pressed against the top of the support frame; a stabilizing spring is wrapped around the outer wall of each of the two adjusting screws; and a stop block is fixedly connected to the bottom of each of the two adjusting screws.
[0009] The above technical solution uses a fixed nut to adjust the screw for lifting and lowering, and under the action of a stabilizing spring, the adjusted screw can remain stable, and the receiving plate can position and fix the bottom of the casting.
[0010] The present invention is further configured such that the end faces of the two stabilizing springs abut against the bottom of the support frame and the top of the stop block, respectively.
[0011] The above technical solution utilizes a stabilizing spring to reinforce and stabilize the position of the adjusted screw, preventing it from shaking during clamping.
[0012] The present invention is further configured such that: the clamping mechanism includes a rotating block rotatably connected to the center of the top of the support frame; connecting rods are rotatably connected to both ends of the rotating block; sliding plates are rotatably connected to the end faces of the two connecting rods; clamping blocks are bolted to the top of the two sliding plates; and a cylinder is connected to the middle of one of the sliding plates via a connecting block bolted to it.
[0013] The above technical solution involves starting the cylinder, which drives the connecting block at the end face to move, causing it to slide the top-connected slide plate. This, in turn, uses the connecting rod to drive the rotating block to rotate on the support frame, causing the connecting rod at the other end to drive the slide plate to slide, thereby completing the clamping and fixing of the casting.
[0014] The present invention is further configured such that: the bottom of each of the two slide plates is bolted to a slide seat near the end face, and the slide seat is slidably connected to a guide rail bolted to the top of the support frame.
[0015] The above technical solution facilitates stable sliding of the slide block on the guide rail when the slide is driven, thereby enabling stable clamping and fixing of the placed casting.
[0016] The present invention is further configured such that: both clamping blocks are L-shaped, and multiple anti-slip grooves are provided on their opposite surfaces, and multiple pressure sensors are installed inside them, with the multiple anti-slip grooves and pressure sensors being arranged alternately.
[0017] The above technical solution facilitates the use of multiple anti-slip grooves to prevent slippage of the casting during clamping, thus preventing it from shifting during milling. Furthermore, the multiple pressure sensors can provide timely feedback on the pressure generated during clamping and provide adaptive flexible clamping and fixation.
[0018] The beneficial effects of this utility model are as follows: 1. The large casting adaptive flexible clamping milling platform proposed in this utility model has a receiving component set in the middle of the milling platform, which can fix the bottom of the placed casting and adjust the appropriate height according to the size of the casting, thereby improving its stability during the milling process. 2. The large casting adaptive flexible clamping milling platform proposed in this utility model has clamping mechanisms on both sides of the milling platform, which can clamp the casting in an anti-slip manner through the internal flexible clamping blocks, and has multiple pressure sensors that can adaptively clamp and fix the casting according to the changes in clamping force.

[0021] 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.
[0022] likeFigures 1-5 As shown, a large casting adaptive flexible clamping milling platform includes a base 1. The top of the base 1 has symmetrically arranged mounting slots 11 near its end face, facilitating the fixing of the base 1 in position using bolts. A support frame 2 is fixedly connected to the top of the base 1. The support frame 2 has an H-shaped structure, and a clamping mechanism 4 is provided on the top of the support frame 2 for flexible clamping and fixing of the casting. The clamping mechanism 4 includes a rotating block 41 rotatably connected to the center of the top of the support frame 2. Connecting rods 42 are rotatably connected to both ends of the rotating block 41, and the end faces of both connecting rods 42 are rotatable. Two slide plates 43 are connected, and each slide plate 43 has a slide block 431 bolted to its bottom near the end face. The slide block 431 is slidably connected to the guide rail 21 bolted to the top of the support frame 2, so that when the slide plate 43 is driven, it can slide stably on the guide rail 21 via the slide block 431, thereby stably clamping and fixing the placed casting. Each slide plate 43 has a clamping block 44 bolted to its top. Both clamping blocks 44 are L-shaped and have multiple anti-slip grooves 441 on their opposite surfaces. Multiple Kistlers are installed inside each clamping block 44. The pressure sensor 442 of model 9321B has multiple anti-slip grooves 441 and pressure sensors 442 arranged alternately. This facilitates the anti-slip treatment of the casting in the clamping by using the multiple anti-slip grooves 441, preventing displacement during milling. The multiple pressure sensors 442 can provide timely feedback on the pressure generated during clamping and provide adaptive flexible clamping and fixation. A cylinder 45 is connected to the middle of one of the slide plates 43 through a connecting block 432 bolted to it. When the cylinder 45 is activated, its drive rod moves the connecting block 432 at the end face, causing it to slide the slide plate 43 connected to the top. This, in turn, causes the rotating block 41 to rotate on the support frame 2 through the connecting rod 42 at its other end, causing the slide plate 43 to slide, thereby completing the clamping and fixation of the casting.
[0023] like Figure 3As shown, the top of the support frame 2 is bolted to a receiving component 3, which includes a receiving plate 31. Two adjusting screws 32 are symmetrically fixed to the bottom of the receiving plate 31 near its end face. The two adjusting screws 32 pass through the top of the support frame 2, and each adjusting screw 32 has a threaded fixing nut 33 on its outer wall, which abuts against the top of the support frame 2. Each adjusting screw 32 has a stabilizing spring 34 wrapped around its outer wall, with the end faces of the two stabilizing springs abutting against the bottom of the support frame 2 and the top of the stop block 35, respectively. The stabilizing springs 34 reinforce and stabilize the position of the adjusted screws 32 after adjustment, preventing wobbling during clamping. Each adjusting screw 32 has a stop block 35 fixedly connected to its bottom. The fixing nut 33 is used to adjust the screws 32 by raising and lowering them, and the stabilizing springs 34 ensure the adjusted screws 32 remain stable, allowing the receiving plate 31 to position and fix the bottom of the casting.
[0024] In use, this invention first uses the fixing nut 33 to adjust the screw 32 for lifting and lowering. Under the action of the stabilizing spring 34, the adjusted screw 32 can remain stable. Then, the casting is placed on the receiving plate 31, and the cylinder 45 is started. Its drive rod drives the connecting block 432 on the end face to move, which drives the top connected slide plate 43 to slide. Thus, the connecting rod 42 drives the rotating block 41 to rotate on the support frame 2, so that the connecting rod 42 connected to its other end drives the slide plate 43 to slide, thereby completing the clamping and fixing of the casting.
