Description

Technical Field

[0001] This utility model belongs to the field of tooling for mechanical processing equipment, and specifically relates to a dual-station, three-process thin-walled shell drilling, milling, and reaming integrated hydraulic clamp. Background Technology

[0002] Thin-walled shells typically refer to structures where the ratio of shell thickness *t* to its radius of curvature *R* is ≤1 / 20. Due to the thinness and lightness of the workpiece, ordinary manual clamping can easily cause micro-deformation, making it impossible to guarantee machining accuracy. Furthermore, manual clamping, multiple processes, multiple machine tools, and multiple personnel involved in the operation result in significant errors, ultimately failing to guarantee the dimensional accuracy of the thin-walled shell during machining and affecting product quality. Simultaneously, drilling, milling, and reaming require three separate processes, consuming more machine tools and personnel, resulting in high time and labor costs, low production efficiency, and high processing costs. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a dual-station, three-process thin-walled shell drilling, milling, and reaming integrated hydraulic clamp that has a simple structure, ensures machining dimensional accuracy, and has high production efficiency.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: a dual-station, three-process thin-walled shell drilling, milling, and reaming integrated hydraulic chuck includes an oil circuit base plate. Its characteristic is that an oil circuit is provided within the oil circuit base plate, and two stations are provided on the left side of the oil circuit base plate. The front left side is station one for process one, and the rear left side is station two for process one. A centering support sleeve is installed at station one for process one, and two hydraulic lever cylinders are symmetrically fixedly installed around the centering support sleeve. A movable pressure plate is installed on each of the hydraulic lever cylinders. A limiting rod is provided on the upper edge of the centering support sleeve one. The components and component structures installed at the second station of the first process are the same as those at the first station of the first process. An oil circuit vertical plate is provided on the oil circuit base plate on the right side of the two stations of the first process. An oil circuit is provided inside the oil circuit vertical plate. Two stations are provided on the right side of the oil circuit vertical plate. The rear part of the right side is the second station of the second process, and the front part of the right side is the first station of the second process. The centering support sleeve two is installed on the second station of the second process. A hydraulic angle cylinder is fixedly installed on the right side of the centering support sleeve two. One end of the rotating pressure rod is installed at the top of the cylinder, and the other end of the rotating pressure rod is equipped with a pressure cap. A limiting pin and an anti-misalignment guide rod are provided on the edge of the second centering support sleeve. The equipment components and component structures installed at the first station of the second process are the same as those at the second station of the second process. Two stations are located on the right side of the two stations of the second process; the front right side is the first station of the third process, and the rear right side is the second station of the third process. A third centering support sleeve is installed at the first station of the third process, and two hydraulic lever cylinders are fixedly installed around the third centering support sleeve. A pressure plate is movably mounted on lever cylinder two. An anti-misalignment stop is provided on the upper edge of centering support sleeve three. A limit pin two is provided between the anti-misalignment stop and hydraulic lever cylinder two. The equipment components and component structures installed at station two of the third process are the same as those at station one of the third process.

Oil port one and oil port two are connected to the oil circuit in the oil circuit base plate, the oil circuit in the oil circuit vertical plate, hydraulic lever cylinder one, hydraulic lever cylinder two, and hydraulic angle cylinder.

[0005] The beneficial effects of this utility model are: the dual-station three-process thin-walled shell drilling, milling and reaming integrated hydraulic clamp is a modified design of the existing three-process manual clamping thin-walled shell drilling, milling and reaming into a hydraulic clamping thin-walled shell drilling, milling and reaming integrated hydraulic clamping thin-walled shell, which ensures the processing quality. At the same time, it integrates the three processes of drilling, milling and reaming into one machine tool, and processes them on one machine, saving time and effort, improving equipment utilization, increasing production capacity, and thus greatly improving production efficiency.

One end of a rotatable rotating pressure rod 12 is installed on the top of the hydraulic angle cylinder 10, and a pressure cap 11 is installed on the other end of the rotating pressure rod 12. After the workpiece 19 is installed in the centering support sleeve 2 9, the pressure cap 11 is pressed onto the workpiece 19 by rotating the rotating pressure rod 12. The components and component structures installed at the first station 2-1 of the second process and the second station 2-2 of the second process are the same. On the right side of the two workstations in the second process, on the oil circuit base plate 1, are two workstations for the third process. The first workstation for the third process is located at the front right, and the second workstation for the third process is located at the rear right. A centering support sleeve 3 16 is installed on the first workstation for the third process 1 1 3. Two hydraulic lever cylinders 2 17 are fixedly installed around the centering support sleeve 3 16.

[0010] The working procedure of this utility model is as follows: When using the dual-station, three-process thin-walled shell drilling, milling, and reaming integrated hydraulic chuck, one side of the large cavity of two workpieces 19 is placed downwards into the centering support sleeve 1 of the first process station 1-1 and the first process station 1-2, respectively. The workpieces 19 are limited by the limiting rod 7, and then the pressure plate 15 is pressed on the workpieces 19. The small ends of the two workpieces 19 are inserted into the centering support sleeve 2 of the second process station 2-1 and the second process station 2-2, respectively. The limiting pin 18 is used to limit them, and the anti-misalignment guide rod 13 is used to position the workpieces 19. Then the pressure cover 11 is pressed on the workpieces 19. The small ends of the two workpieces 19 are inserted into the centering support sleeve 3 of the third process station 1-3 and the third process station 1-4, respectively. The limiting pin 25 is used to limit them, and the anti-misalignment stop rod 14 is used to position the workpieces 19. Then the pressure plate 28 is pressed on the workpieces 19. Start the hydraulic system and introduce oil from port 3-1 of the hydraulic circuit block 3. The oil is supplied to the hydraulic lever cylinder 6, hydraulic lever cylinder 17, and hydraulic angle cylinder 10 through the oil circuit in the hydraulic circuit base plate 1 and the hydraulic circuit vertical plate 2. This causes the pressure plate 5 to press the two workpieces 19 at station 1-1 of the first process and station 1-2 of the first process. The pressure cover 11 presses the two workpieces 19 at station 2-1 of the second process and station 2-2 of the second process. The pressure plate 18 presses the two workpieces 19 at station 1-3 of the third process and station 1-4 of the third process. After pressing, the drilling, milling, and reaming processes can be performed simultaneously to process the six workpieces 19. After processing, the oil is discharged from port 3-2, and the workpieces 19 can be released and removed. The above process can be repeated.
