Description

Technical Field

[0001] This utility model relates to a dual-station zero-point quick-change alignment device, belonging to the field of mechanical processing technology. Background Technology

[0002] In the field of machining, especially in the processing of complex structural parts, clamping and alignment are crucial steps to ensure machining accuracy and production efficiency. The burner tailpipe, a typical irregularly shaped thin-walled part, has a complex structure, composed of multiple welded components, including the outlet flange, irregularly shaped cylinder, inlet guide ring, guide block, and outlet positioning block. Due to its wall thickness of only 3mm and a 30° angle between the inlet and outlet, clamping and alignment on the machining equipment is time-consuming, typically requiring about 4 hours. This not only reduces the efficiency of the machining equipment but also affects the mass production of the product.

[0003] Traditional machining equipment involves complex and time-consuming clamping and alignment processes, failing to meet the high efficiency and precision requirements of modern manufacturing. Especially in mass production, the lengthy alignment process severely restricts production efficiency and increases production costs. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-station zero-point quick-change alignment device to address the above-mentioned problems. This device can effectively solve the problem of low equipment efficiency caused by long alignment time of parts on the processing equipment, thereby improving the utilization value of the processing equipment. The device has a simple structure and reasonable design. Parts are not prone to vibration during clamping and alignment, which reduces the processing cycle of the workpiece, improves processing efficiency, and reduces the production and manufacturing cost of the product.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A dual-station zero-point quick-change alignment device includes a worktable, on which three-axis adjustment components are respectively provided on both sides along the X-axis direction, and dial indicators are provided on the three-axis adjustment components; the worktable is also provided with two rotating platforms, which are located between the two three-axis adjustment components, and zero-point quick-change bases are provided on the rotating platforms.

[0007] Alternatively, the bottom of the workbench may be provided with anchor bolts.

[0008] Alternatively, the three-axis adjustment assembly includes an X-axis track, a Z-axis guide rail on the X-axis track, a Y-axis extension rod on the Z-axis guide rail, and a dial indicator at the end of the Y-axis extension rod.

[0009] Alternatively, the X-axis track can be a lead screw.

[0010] Alternatively, the Z-axis guide rail can be a linear guide rail.

[0011] Alternatively, the Y-axis extension rod can be detachably connected to the Z-axis guide rail.

[0012] Alternatively, the rotating platform may be connected to a rotary shaft servo motor via a speed reducer.

[0013] Optionally, the workbench is also equipped with a grating ruler for measuring the angle of the rotating platform.

[0014] Alternatively, a control cabinet may be included, which connects the three-axis adjustment assembly and the rotary platform.

[0015] Alternatively, the control cabinet may be connected to a control handwheel for controlling the three-axis adjustment assembly and / or the rotary platform, the control handwheel being an electronic handwheel.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] 1. The dual-station zero-point quick-change alignment device provided by this utility model, by adopting a zero-point base system, can quickly connect with processing equipment to achieve rapid clamping and alignment of parts. Simultaneously, the dual-station design allows the device to serve two processing machines at the same time, further improving alignment efficiency, realizing efficient utilization of processing equipment, and providing strong support for mass production.

[0018] 2. This utility model provides a dual-station zero-point quick-change alignment device, which transfers the alignment time originally spent on the processing equipment to the quick-change alignment device. This not only solves the problem of excessively long alignment time in traditional processing equipment, but also improves operational convenience and safety through structural optimization and automated control, reducing the difficulty and risk for workers. The application of this device significantly enhances the usability of processing equipment and shortens the product production cycle. The X-axis lead screw and Z-axis guide rail have an accuracy of within 0.04mm, ensuring alignment precision. Combined with the functions of the rotary platform and PLC controller, the dial indicator not only measures the positional deviation of the part for precise position alignment, but also establishes the zero-point position of the part; equivalently, the adjustment component can not only align but also establish a zero point.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] A dual-station zero-point quick-change alignment device, such as Figure 1 As shown, the system includes a worktable 1, on which three-axis adjustment components are respectively provided on both sides along the X-axis direction, and dial indicators 2 are provided on the three-axis adjustment components; the worktable 1 is also provided with two rotating platforms 3, which are located between the two three-axis adjustment components, and zero-point quick-change bases 4 are provided on the rotating platforms 3.

[0024] The worktable 1 is equipped with two rotary platforms 3, each with a zero-point quick-change base 4. This dual-station design allows the device to serve two processing machines simultaneously, significantly improving alignment efficiency. Three-axis adjustment components (X, Y, and Z axes) are located on both sides of the worktable 1, each equipped with a dial indicator 2. These three-axis adjustment components allow for precise positional adjustment of the part in the X, Y, and Z directions, ensuring the part's clamping position meets processing requirements. The rotary platforms 3 are driven by servo motors, enabling precise rotational movement. The zero-point quick-change base 4 matches the zero-point base of the processing equipment, enabling rapid clamping and positioning of the part, reducing the time required for traditional clamping and alignment. The dial indicator 2 measures the part's positional deviation; combined with the three-axis adjustment components and rotary platforms 3, it allows for precise alignment of the part. Through a human-machine interface and electronic handwheel control, the operator can adjust the part's position in real time to ensure alignment accuracy. Furthermore, the zero-point quick-change base 4 set on the rotary platform 3 can be the same base or different bases to match the positioning of the same processing equipment or different processing equipment.

[0025] In another specific embodiment, the bottom of the workbench 1 is provided with anchor bolts 5. The anchor bolts 5 can firmly fix the workbench 1 to the ground, preventing the device from shifting or shaking due to vibration or external interference during operation. In addition, the anchor bolts 5 are usually adjustable, and the levelness of the workbench 1 can be corrected by adjusting the height of the bolts.

[0026] In another specific implementation, the three-axis adjustment assembly includes an X-axis track 6, a Z-axis guide rail 7 mounted on the X-axis track 6, a Y-axis extension rod 8 mounted on the Z-axis guide rail 7, and a dial indicator 2 at the end of the Y-axis extension rod 8. The axis adjustment assembly, through the combination of the X-axis track 6, the Z-axis guide rail 7, and the Y-axis extension rod 8, achieves precise adjustment of the part in the X, Y, and Z directions. The X-axis track 6 is used for horizontal left-right movement, the Z-axis guide rail 7 for vertical up-down movement, and the Y-axis extension rod 8 for forward and backward extension and adjustment. This multi-directional adjustment capability allows the device to adapt to parts of different shapes and sizes, ensuring that the part's position can be accurately aligned in all directions, meeting the requirements of high-precision machining. The design of the Y-axis extension rod 8 allows the dial indicator 2 to flexibly extend to different positions on the part, especially in the alignment of complex-shaped parts, covering more measurement points.

[0027] In another specific implementation, the X-axis track 6 is a lead screw. The lead screw can efficiently transmit the power of the servo motor to the X-axis track 6, driving the Z-axis guide rail 7 and the Y-axis extension rod 8 to move in the X-axis direction. The lead screw drive has high transmission efficiency, ensuring smooth movement and fast response speed, and is suitable for transmitting power over long track distances, covering a large working range and meeting the needs of dual-station devices.

[0028] In another specific implementation, the Z-axis guide rail 7 is a linear guide rail. Linear guide rails possess high precision and low friction characteristics, ensuring smooth movement of the Y-axis extension rod 8 in the vertical direction. Furthermore, they are more precise, ensuring that the dial indicator 2 achieves high-precision vertical position adjustment, thus improving the reliability of the alignment results. Further, the Z-axis guide rail 7 is connected to a track-type cover, which protects the wiring connected to the Z-axis guide rail 7.

[0029] In another specific implementation, the Y-axis extension rod 8 is detachably connected to the Z-axis guide rail 7. The detachable design of the Y-axis extension rod 8 allows the operator to flexibly adjust its length or position according to specific alignment requirements. Furthermore, the Y-axis extension rod 8 is secured by clips and bolts, ensuring that the dial indicator 2 can accurately align with the measuring points of the part, thereby improving the efficiency and accuracy of the alignment operation.

[0030] In another specific implementation, the rotary platform 3 is connected to a rotary shaft servo motor 9 via a reducer. This significantly improves the rotational accuracy, motion smoothness, and load capacity of the device. The combination of the servo motor and the reducer ensures high precision and high torque output of the rotary platform 3 at low speeds, meeting the requirements for aligning complex parts.

[0031] In another specific implementation, the workbench 1 is also equipped with a grating ruler for measuring the angle of the rotating platform 3. The real-time feedback function of the grating ruler makes the angle control of the rotating platform 3 more precise and reliable. The grating ruler is installed at the bottom of the rotating platform 3 to measure the angular position of the rotating platform 3 in real time. The PLC reads and displays the correct position information of the grating ruler; manual coordinate compensation is performed according to the measured position; and the monitoring and operation of the rotation axis coordinate data are realized.

[0032] In another specific implementation, a control cabinet 12 is also included, which connects the three-axis adjustment assembly and the rotary platform 3. The control cabinet 12 serves as the core control unit of the device, centrally managing the motion control of the three-axis adjustment assembly and the rotary platform 3. The operator can easily adjust the position of each motion axis and the angle of the rotary platform 3 through the control cabinet 12, without needing to operate multiple independent control systems separately. In this embodiment, this is achieved by controlling a servo motor, which in turn controls the X-axis lead screw 6, the Z-axis guide rail 7, and the rotary table. The control cabinet 12 is a PLC or similar automated control system, capable of automatically controlling the motion of the three-axis adjustment assembly and the rotary platform 3 according to a preset program. The operator only needs to input the target parameters, and the system can automatically complete the alignment operation. Furthermore, the PLC can read the position of the grating ruler and the X-axis and Z-axis. Further, a control cabinet connecting all electrical equipment is also included. The control cabinet 12 is also connected to a human-machine interface 10, which can interact with and display data from the control cabinet 12, showing the position of the Y-axis extension rod 8 relative to the X-axis lead screw 6 and the Z-axis guide rail 7.

[0033] In another specific implementation, the control cabinet 12 is connected to a control handwheel 11 for controlling the three-axis adjustment assembly and / or the rotary platform 3. The control handwheel 11 is an electronic handwheel. The electronic handwheel is used to manually control the movement of the three-axis adjustment assembly (X and Z axes) and the rotary platform 3. The operator can gradually adjust the position of each motion axis or the angle of the rotary platform 3 by rotating the handwheel. Manual operation uses a hand-cranked pulse controller; parameters are monitored and modified using a touchscreen. The electronic handwheel is integrated with a PLC, enabling real-time feedback of the operator's manual adjustment data and displaying relevant parameters through a human-machine interface. The operator can further adjust the movement state of the device based on the feedback data. Furthermore, the control cabinet 12 and the control handwheel 11 are communicatively connected, and the control handwheel 11 is located at the human-machine interface 10 for convenient operation.

[0034] The dual-station zero-point quick-change alignment device provided in this embodiment operates as follows:

[0035] (1) First, load the part to be aligned onto the machine tool tray, so that the part is in a lightly tightened state but not clamped. Move the part as a whole to the zero point quick change base 4, and place the whole part on the corresponding rotary table 1 through the zero point quick change base 4.

[0036] (2) After adjusting the clamping state between the clamped parts and the rotating platform 3, adjust the Y-axis extension rod 8, which is fixed to the Z-axis guide rail 7 by buckles and bolts; ensure that its extended state can be used to place the dial indicator 2 for alignment.

[0037] (3) After adjusting the Y-axis extension rod 8, use the control handwheel 11 to control the Z-axis guide rail 7 or the Y-axis extension rod 8 to slide on the corresponding X-axis rail 6 or the Z-axis guide rail 7. At the same time, in conjunction with the rotation of the corresponding rotary platform 3, the dial indicator 2 will align the various machining surfaces of the clamped parts. The alignment process involves adjusting the clamping state on the pallet and adjusting the mechanical parameters of the alignment process in conjunction with the feedback data from the human-machine interface.

[0038] (4) After the alignment result of the part and tooling on the rotary platform 3 meets the processing requirements, fix the clamping state between the tooling and the pallet, and at the same time fix the clamping state between the part and the tooling.

[0039] (5) Remove the clamped parts and tooling tray, and move the whole assembly to a processing equipment with the same zero-point reference.

[0040] (6) Quickly place the workpiece on the corresponding processing equipment according to the alignment status, and carry out the subsequent processing steps.
