[0002] When CNC machine tools process workpieces, a fixture is needed to fix the workpiece so that the cutting tool can process the workpiece.

[0003] Patent application CN102343506A discloses a method and clamping tool for machining motor housings using a CNC machine tool. This method completes the machining of the motor housing blank in a single clamping operation. The clamping tool includes a tool base with outwardly extending lower and upper fixed arms. The lower fixed arm is a flat plate structure with four symmetrically arranged motor housing foot fixing components on both sides. A motor housing clamping and fixing device is provided on the upper fixed arm. This method offers high efficiency and good machining quality. The dedicated clamping tool has a simple structure, provides secure fixing, and is stable and reliable during operation.

[0004] Since the clamping tool involves multiple components (such as the lower fixed arm, upper fixed arm, and motor housing foot fasteners), each component needs to be adjusted and fixed individually when clamping the workpiece, which may consume a lot of time and effort. The cumbersome installation process may reduce the overall production efficiency. To address the above issues, we have introduced a clamping tool for machining motor housings on CNC machine tools.

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] The clamping tool disclosed in this utility model for machining motor housings on CNC machine tools is mainly used in mechanical equipment scenarios.

[0023] Reference Figures 1 to 4 A clamping tool for machining motor housings on a CNC machine tool includes: a fixed mounting frame 1, a motor housing 2 disposed inside the fixed mounting frame 1, a fixed base 3 disposed at the bottom of the motor housing 2, a connecting plate 4 fixedly connected to the top of the fixed base 3, one side of the connecting plate 4 being fixed to one side of the motor housing 2 by bolts, a placement groove 18 being provided at the bottom of the inner wall of the fixed mounting frame 1, the interior of the placement groove 18 being slidably connected to the exterior of the fixed base 3, and a first fixing component and a second fixing component being respectively disposed at the top of the fixed mounting frame 1 and the bottom of the inner wall, the first fixing component being used to fix the motor housing 2, and the second fixing component being used to restrict the fixed base 3.

[0024] In the above technical solution, considering that the clamping tool involves multiple components (such as the lower fixed arm, upper fixed arm, and motor housing foot fixing parts), each component needs to be adjusted and fixed one by one when clamping the workpiece, which may consume a lot of time and effort. The cumbersome installation process may lead to a decrease in overall production efficiency. To solve this problem, the specific operation is as follows: the connecting plate 4 is fixed to the motor housing 2 with bolts, the fixing base 3 is installed under the motor housing 2, and then the fixing base 3 is slid into the placement groove 18. The first fixing component is used to fix it from the top of the motor housing 2, and then the second fixing component is used to fix the fixing base 3 from both sides. The operator can complete the clamping process more quickly, reducing the complexity of the operation. This is especially user-friendly for novice or less skilled operators, reducing the clamping time for each workpiece, thereby improving overall production efficiency and meeting the needs of mass production.

[0025] Reference Figures 1 to 4 In a preferred embodiment, the first fixing component further includes a cylinder 5, which is disposed on the top of the fixing bracket 1. The bottom of the cylinder 5 extends into the interior of the fixing bracket 1 and is fixedly connected to a pressing plate 6. A rubber pad 7 is fixedly connected to the bottom of the pressing plate 6, and the bottom of the rubber pad 7 abuts against the top of the motor housing 2. The second fixing component includes two mounting plates 8, which are equidistantly disposed on the bottom of the inner wall of the fixing bracket 1. Two mounting blocks 9 are fixedly connected to the top of the mounting plates 8, and a rocker arm 10 is rotatably connected between one side of the two mounting blocks 9. A groove 13 is provided on one side of the rocker arm 10. A gravity block 14 is slidably connected inside the groove 13. Connecting blocks 17 are fixedly connected to both sides of the mounting plate 8. The connecting blocks 17 are fixed to the fixed mounting bracket 1 by bolts. A fixing block 11 is fixedly connected to the bottom of the rocker 10. A fixing groove 12 is opened on the top of the fixed base 3. The bottom of the fixing block 11 abuts against the bottom of the inner wall of the fixing groove 12. A threaded rod 15 is threadedly connected inside the mounting plate 8. One end of the threaded rod 15 extends to the outside of the mounting plate 8 and is rotatably connected to a movable block 16. The bottom of the movable block 16 is slidably connected to the top of the mounting plate 8. One side of the movable block 16 is set as an inclined surface.

[0026] In the above technical solution, considering that the clamping tool involves multiple components (such as the lower fixed arm, upper fixed arm, and motor housing foot fixing parts), each component needs to be adjusted and fixed individually when clamping the workpiece, which may consume a lot of time and effort. The cumbersome installation process may lead to a decrease in overall production efficiency. To solve this problem, the specific operation is as follows: Use bolts to fix the connecting plate 4 to the motor housing 2, install the fixing base 3 under the motor housing 2, then slide the fixing base 3 into the placement groove 18, and then start the cylinder 5 to extend downwards, thereby driving the pressing plate 6 to move downwards, using the rubber pad 7 to lift the press plate from the motor housing. Press and fix the top of 2, then rotate the two sets of threaded rods 15 to drive the movable block 16 to move on the mounting plate 8, so that the inclined surface of the movable block 16 contacts the gravity block 14 and applies pressure to it, lifting the gravity block 14 along the inclined surface and lifting one side of the rocker 10. The other side of the rocker 10 rotates downward, while the fixing block 11 enters the fixing groove 12 and abuts against it, thereby fixing the fixing base 3. Multiple fixation is achieved to ensure the stability of the motor housing during the processing, reduce vibration and displacement, improve processing accuracy, and make it easier for operators to complete the clamping, reducing the complexity of operation.

[0027] Working principle: In use, the connecting plate 4 is fixed to the motor housing 2 with bolts, and the fixing base 3 is installed under the motor housing 2. Then, the fixing base 3 is slid into the placement groove 18. Then, the cylinder 5 is activated to extend downward, thereby driving the pressing plate 6 to move downward. The rubber pad 7 is used to press and fix it from the top of the motor housing 2. Then, the two sets of threaded rods 15 are rotated to drive the movable block 16 to move on the mounting plate 8, so that the inclined surface of the movable block 16 contacts the gravity block 14 and applies pressure to it, lifting the gravity block 14 along the inclined surface and lifting one side of the rocker 10. The other side of the rocker 10 rotates downward, and at the same time, the fixing block 11 enters the fixing groove 12 and abuts against it, thereby fixing the fixing base 3. The operator can complete the clamping process more quickly. All contents not described in detail in this manual are existing technologies known to those skilled in the art.

[0028] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
