Description

Technical Field

[0001] This utility model relates to the field of guide ring processing technology, specifically a fixture for processing guide rings of hydraulic cylinders. Background Technology

[0002] Hydraulic cylinder guide rings, also known as support rings or guide sleeves, are one of the core sealing and guiding components of hydraulic cylinders. Among them, the open-ended annular guide ring can be directly locked into the groove of the piston rod or cylinder barrel through elastic deformation, without the need to disassemble the end connectors, which greatly simplifies the assembly and replacement process. It is especially suitable for structures with fixed sealing caps at both ends of the piston rod that cannot be installed as a whole, or for scenarios that require frequent maintenance, such as construction machinery and small hydraulic actuators. The final stage of processing the open-ended annular guide ring requires cutting the opening.

[0003] Currently, in order to provide stable support for the guide ring and improve cutting accuracy, the guide ring is usually placed on the outside of the cylindrical mold for sequential cutting. However, different molds need to be changed when processing guide rings of different sizes, which limits the scope of application and requires the use of different types of molds. This problem has not been solved in the existing technology. Utility Model Content

By setting up a clamping component, the guide ring can be clamped and fixed, thereby improving the cutting accuracy. By setting up an adjustment component, the spacing of the clamping component can be adjusted to accommodate guide rings of different diameters.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3 This utility model provides a technical solution:

[0024] A clamping fixture for machining a hydraulic cylinder guide ring includes two sets of clamping components for clamping the guide ring body 1. The clamping components include a placement seat 2 and a clamping block 3 symmetrically arranged on the inner and outer sides of the guide ring body 1. The clamping block 3 is slidably engaged with a placement groove opened on the top of the placement seat 2. The placement seat 2 is fixedly installed on a first mounting seat 4, and the clamping block 3 is fixedly installed on a second mounting seat 5. A cutting groove 16 is opened on one side of the clamping components for an external cutting blade to pass through.

[0025] By setting up a clamping assembly, the guide ring body 1 can be stably positioned. The clamping assembly clamps the guide ring body 1 through the symmetrical cooperation of the placement seat 2 and the clamping block 3. The placement groove at the top of the placement seat 2 provides a bottom support surface for the guide ring body 1, while the inner clamping block 3 can slide along the placement groove, applying a clamping force from the inner ring of the guide ring outward, forming a clamping effect with the support of the placement seat 2. This design can not only avoid excessive clamping force causing deformation of the guide ring body 1, but also ensure that the guide ring body 1 maintains coaxiality during processing through two sets of symmetrically distributed clamping points. Especially when cutting the opening, it can prevent the displacement caused by vibration and ensure the cutting accuracy. At the same time, the cutting groove 16 reserved on one side of the clamping assembly provides a dedicated channel for the cutting blade, avoiding interference between the tool and the clamping assembly, further improving processing safety and cutting quality.

[0026] It also includes an adjustment assembly for adjusting the spacing of the clamping components. The adjustment assembly includes a first bidirectional lead screw 6 and a second bidirectional lead screw 7. Two sets of first movable seats 8 are symmetrically mounted on the surface of the first bidirectional lead screw 6. The first movable seats 8 are fixedly connected to the bottom of the first mounting base 4. Two sets of second movable seats 9 are symmetrically mounted on the surface of the second bidirectional lead screw 7. The second movable seats 9 are fixedly mounted to the bottom of the second mounting base 5. The first mounting base 4 and the second mounting base 5 are slidably engaged with the top of the processing table 10. The processing table 10 has a moving groove 11. The first movable seats 8 and the second movable seats 9 pass through the moving groove 11 and are slidably engaged with the moving groove 11. The lead screw 6 and the second bidirectional lead screw 7 are vertically distributed. Both ends of the first bidirectional lead screw 6 and the second bidirectional lead screw 7 are rotatably mounted inside the mounting plate 12. The mounting plate 12 is fixedly mounted on the bottom of the processing table 10. A first motor 13 and a second motor 14 are respectively fixedly mounted on the outer sides of the two sets of mounting plates 12. The output end of the first motor 13 is connected to one end of the first bidirectional lead screw 6, and the output end of the second motor 14 is connected to one end of the second bidirectional lead screw 7. The second movable seat 9 has a through hole 15, which slides with the first bidirectional lead screw 6 with a clearance fit. The processing table 10 is fixedly mounted on the top of the base 17. The first motor... Motor 13 and Motor 14 have a self-locking function and are electrically connected to the control box at the bottom of base 17. The control box is used to control Motor 13 and Motor 14. The control box adopts a modular layout, with a microprocessor integrated main control circuit board at its core. A central control chip, motor drive chip, and signal conditioning circuit are soldered onto this circuit board. The central control chip is responsible for receiving external operation commands (such as manual adjustment buttons and CNC system signals) and outputting motor forward / reverse rotation, start / stop, and speed control signals according to a preset program. Two independent motor drive modules are electrically connected to the main control circuit board. Each drive module... Each motor is equipped with a power amplifier transistor and a relay, which respectively drive the first motor 13 and the second motor 14. The relays are connected in series with the motor power supply circuit. The normally closed contacts of the relays and the self-locking structures of the first motor 13 and the second motor 14 form a double self-locking mechanism. When the first motor 13 and the second motor 14 stop running, the relays automatically cut off the power supply. At the same time, the self-locking mechanism inside the motor (such as worm gear transmission or electromagnetic braking device) locks the output shaft to prevent the first bidirectional lead screw 6 and the second bidirectional lead screw 7 from reversing due to external force, which would cause the clamping distance to shift. In addition, the control box is also equipped with a power conversion module, which can convert the external 220V AC power into the DC voltage (such as 24V) required for motor drive and the low-voltage DC power (such as 5V) required for the main control circuit. It is also equipped with an overload protection fuse and a leakage protection chip. When the motor load is too large or a short circuit or leakage occurs in the circuit, the fuse blows quickly and the leakage protection chip is triggered to cut off the power, so as to avoid damage to the motor and control components.The inner wall of the control box is also equipped with terminal blocks and a cooling fan. The terminal blocks are used to organize the wiring between the motor, external control panel, and main control board. The cooling fan creates air convection through ventilation holes in the box wall, reducing the heat generated by the drive module and power module during operation and ensuring the control box maintains stable performance during long-term operation.

[0027] By setting up adjustment components, the versatility of this device is improved. Through the coordinated action of the first bidirectional lead screw 6 and the second bidirectional lead screw 7, two sets of clamping components are driven to complete synchronous spacing adjustment. The first bidirectional lead screw 6 drives the two sets of first moving seats 8 to move in opposite directions or towards each other through the symmetrical thread on the surface, thereby controlling the opening and closing spacing of the outer placement seat 2 to adapt to guide ring bodies 1 with different outer diameters. The second bidirectional lead screw 7 drives the inner pressing block 3 to move synchronously through the same principle to adjust the inner ring clamping size. The two adopt a vertically distributed layout. The through hole 15 on the second moving seat 9 slides with the first bidirectional lead screw 6 to ensure that the two sets of adjustment actions do not interfere with each other. The lead screw structure driven by the first motor 13 and the second motor 14 can achieve precise spacing fine adjustment to meet the clamping requirements of guide rings of different specifications. Multiple models of products can be processed without changing the fixture, which greatly reduces changeover time and improves equipment utilization and production efficiency.

[0028] In practical use, install the device in the designated position. First, according to the dimensions of the guide ring body 1 to be processed, start the first motor 13 and the second motor 14 via the control box: The first motor 13 drives the first bidirectional lead screw 6 to rotate, causing the two sets of first movable seats 8 and the first mounting seats 4 and placement seats 2 connected to them to move synchronously, adjusting the distance between the two sets of placement seats 2 to match the outer diameter of the guide ring; The second motor 14 drives the second bidirectional lead screw 7 to rotate, causing the second movable seat 9 and the second mounting seats 5 and the clamping block 3 connected to it to move synchronously, so that the clamping block... 3 and the placement groove on the top of the placement seat 2 form a clamping space that matches the inner diameter of the guide ring; then the guide ring body 1 is placed into the placement groove, and the second motor 14 is finely adjusted again through the control box so that the clamping block 3 presses against the guide ring body 1 from the inside. The clamping of the placement seat 2 and the clamping block 3 from the inside and outside achieves a stable clamping. After clamping, the blade of the external cutting device extends into the cutting groove 16 on one side of the clamping component to cut the guide ring body 1. When changing guide rings of different sizes, the above motor adjustment steps can be repeated. There is no need to change the clamping component, making the operation convenient and efficient.
