Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder manufacturing technology, specifically to a positioning fixture for hydraulic cylinder manufacturing. Background Technology

[0002] A hydraulic cylinder, also known as a hydraulic actuator, is a hydraulic actuator that converts hydraulic energy into mechanical energy to perform linear reciprocating motion (or oscillating motion). It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device and has no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. Precise positioning is required during the production process of hydraulic cylinders.

[0003] The patented technology, authorized by announcement number CN202684571U, is a hydraulic cylinder production positioning fixture. This technology solves the problems of existing fixtures and jigs being cumbersome to operate, affecting production progress, and prone to inaccurate clamping and positioning, which seriously affects processing quality and impacts the efficiency of production enterprises.

[0004] However, the aforementioned device has the following problems in use: During clamping, it relies on a hydraulic rod for fixation, lacking a good protective structure and making it difficult to adjust to different shapes of the hydraulic cylinder edges. This leads to deformation of the hydraulic cylinder during positioning. Furthermore, after positioning, the hydraulic cylinder production positioning fixture has a fixed position for processing and cannot be adjusted. Therefore, we propose a new hydraulic cylinder production positioning fixture. Utility Model Content

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Please see Figure 1-3This utility model provides a technical solution: a hydraulic cylinder production positioning fixture, comprising: a worktable 1, with an installation groove 2 in the middle of the top of the worktable 1, and symmetrical sliding grooves 3 on both sides of the top of the worktable 1, the sliding grooves 3 being located on both sides of the installation groove 2; a moving component 4, the moving component 4 being disposed in the inner cavity of the installation groove 2, the top of the moving component 4 being fixedly connected to an installation platform 5, the top of the installation platform 5 being symmetrically fixedly connected to a vertical plate 6 on one side, and the top of the installation platform 5 being fixedly connected to a fixing groove 9 on the other side; and a fixing component 7, the fixing component 7 being disposed on the top of the fixing groove 9, and having a plurality of adaptive components 8 disposed on the fixing component 7.

[0021] Specifically, such as Figure 2 , Figure 3 As shown, the fixing assembly 7 includes a worm gear ring 7.1, fixing posts 7.2, connecting plate 7.3, rotating block 7.4, fixing plate 7.5, and sliding plate 7.6. The worm gear ring 7.1 is rotatably connected to the top of the fixing groove 9 via bearings. Several fixing posts 7.2 are arranged circumferentially around the worm gear ring 7.1, and the bottom of the fixing posts 7.2 is fixedly connected to the top of the mounting platform 5. The top of the fixing posts 7.2 is rotatably connected to the connecting plate 7.3, which slides against the top of the worm gear ring 7.1. One side of the top of the connecting plate 7.3 is rotatably connected to a... A rotating block 7.4 is fixedly connected to a fixing plate 7.5 on one side. The fixing plate 7.5 is located in the inner cavity of the worm gear ring 7.1. The bottom of the fixing plate 7.5 slides against the bottom of the inner cavity of the fixing groove 9. Several sliding plates 7.6 are rotatably connected to the top edge of the worm gear ring 7.1 through bearings. A connecting plate 7.3 slides through and is connected to the inner cavity of the sliding plate 7.6. The sliding plate 7.6 plays a good limiting and guiding role for the connecting plate 7.3. Several limiting grooves 10 are evenly opened on the side wall of the fixing plate 7.5. The adaptive component 8 is set in the inner cavity of the limiting groove 10.

[0022] The fixing assembly 7 also includes a worm gear 7.7 and a second motor 7.8. The worm gear 7.7 is rotatably connected between the two vertical plates 6 via bearings, and is meshed with the worm wheel ring 7.1. The second motor 7.8 is fixedly connected to one side of the vertical plate 6, and its output end passes through the vertical plate 6 and is fixedly connected to the worm gear 7.7. After the hydraulic cylinder is placed into the inner cavity of the fixing groove 9, the second motor 7.8 is started, driving the worm gear 7.7 to rotate, thereby driving the worm wheel ring 7.1 to rotate. At this time, the sliding plate 7.6 drives the connecting plate 7.3 to retract inward, so that the rotating block 7.4 drives the fixing plate 7.5 to rotate to a suitable angle and squeeze the side wall of the hydraulic cylinder. At the same time, the adaptive component 8 on the fixing plate 7.5 can adapt its shape according to the specific shape of the hydraulic cylinder side wall, thereby fixing the hydraulic cylinder more stably. The multiple fixing plates 7.5 are arranged in a ring to fix the side wall of the hydraulic cylinder, so that the clamping force can be evenly distributed and the fixation is stable.

[0023] Specifically, such as Figure 3As shown, the adaptive component 8 includes a spring 8.1, a baffle 8.2, a connecting rod 8.3, a limiting plate 8.4, and a retaining ring 8.5. One end of the spring 8.1 is fixedly connected to the inner wall of the limiting groove 10. The baffle 8.2 is fixedly connected to one end of the spring 8.1 and is slidably connected to the inner wall of the limiting groove 10. The connecting rod 8.3 is fixedly connected to one side of the baffle 8.2, and the limiting plate 8.4 is fixedly connected to one side of the connecting rod 8.3. The retaining ring 8.5 is fixedly connected to the opening of the limiting groove 10, and the connecting rod 8.3 slides through the retaining ring 8.5. The inner diameter of the retaining ring 8.5 is smaller than the diameter of the baffle 8.2, which can play a good limiting and guiding role for the connecting rod 8.3 and prevent the connecting rod 8.3 from coming out of the inner cavity of the limiting groove 10. When the hydraulic cylinder is fixed by the fixing component 7, as the fixing plate 7.5 approaches the side wall of the hydraulic cylinder, the limiting plate 8.4 comes into contact with the side wall of the hydraulic cylinder. As the fixing plate 7.5 continues to move, the limiting plate 8.4 pushes the connecting rod 8.3 and the baffle 8.2 into the inner cavity of the limiting groove 10, thereby compressing the spring 8.1. The spring 8.1 generates a reaction force that allows the limiting plate 8.4 to fit tightly against the side wall of the hydraulic cylinder. This makes it suitable for fixing hydraulic cylinders with different outer surfaces, and the fixing is more stable.

[0024] Specifically, such as Figure 2 As shown, the moving component 4 includes a motor 4.1, a threaded rod 4.2, a moving block 4.3, and a slider 4.4. The threaded rod 4.2 is rotatably connected to the inner cavity of the mounting groove 2 via a bearing. The moving block 4.3 is meshed onto the threaded rod 4.2. The slider 4.4 is slidably connected to the inner cavity of the slide groove 3, and the tops of the moving block 4.3 and the slider 4.4 are respectively fixedly connected to the bottom of the mounting platform 5. The slider 4.4 provides good limiting and guiding for the mounting platform 5, making the mounting platform 5 more stable when moving. The motor 4.1 is fixedly connected to one side of the worktable 1, and the output end of the motor 4.1 passes through the inner cavity of the mounting groove 2 and is fixedly connected to one end of the threaded rod 4.2. When it is necessary to adjust the processing position of the hydraulic cylinder, the motor 4.1 is started to drive the threaded rod 4.2 to rotate, thereby driving the moving block 4.3 and its mounting platform 5, fixed component 7, and hydraulic cylinder to move. When it moves to the appropriate position, the motor 4.1 is stopped, and the processing work can continue.

[0025] It should be noted that this utility model is a positioning fixture for hydraulic cylinder production. When positioning the hydraulic cylinder, the hydraulic cylinder is placed in the inner cavity of the fixing groove 9. The motor 7.8 is started, driving the worm gear 7.7 to rotate, which in turn drives the worm wheel ring 7.1 to rotate. At this time, the sliding plate 7.6 drives the connecting plate 7.3 to retract inward, so that the rotating block 7.4 drives the fixing plate 7.5 to rotate to a suitable angle and squeeze the side wall of the hydraulic cylinder. At the same time, the adaptive component 8 on the fixing plate 7.5 can adapt its shape according to the specific shape of the side wall of the hydraulic cylinder, thereby fixing the hydraulic cylinder more stably. The multiple fixing plates 7.5 are arranged in a ring to fix the side wall of the hydraulic cylinder, so that the clamping force can be evenly distributed and the fixation is stable.

[0026] When the hydraulic cylinder is fixed by the fixing component 7, as the fixing plate 7.5 approaches the side wall of the hydraulic cylinder, the limiting plate 8.4 comes into contact with the side wall of the hydraulic cylinder. As the fixing plate 7.5 continues to move, the limiting plate 8.4 pushes the connecting rod 8.3 and the baffle 8.2 into the inner cavity of the limiting groove 10, thereby compressing the spring 8.1. The spring 8.1 generates a reaction force that allows the limiting plate 8.4 to fit tightly against the side wall of the hydraulic cylinder. This makes it suitable for fixing hydraulic cylinders with different outer surfaces, and the fixing is more stable.

[0027] When the machining position of the hydraulic cylinder needs to be adjusted, start motor 4.1 to drive the threaded rod 4.2 to rotate, thereby moving the moving block 4.3 and its mounting platform 5, fixing component 7 and hydraulic cylinder. When it moves to the appropriate position, stop motor 4.1 and the machining work can continue.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
