Description

Technical Field

[0001] This utility model relates to the field of tooling, and in particular to a flow meter production assembly tooling. Background Technology

[0002] Electromagnetic flowmeters use the principle of electromagnetic induction to measure the flow rate of conductive fluids. They mainly consist of an inner tube and a measuring instrument mounted on the outer wall of the inner tube. The measuring instrument measures the flow rate of the fluid passing through the inner tube. During the production of electromagnetic flowmeters, the inner tube needs to be clamped and its posture adjusted; traditional clamping methods are inconvenient for adjusting the posture of the electromagnetic flowmeter.

[0003] Chinese Patent (Publication No. CN109176066A, Publication Date 20190111) discloses a small-diameter electrode assembly fixture for an electromagnetic flowmeter. It includes a placement unit on which the electromagnetic flowmeter flange is placed to prevent it from rotating during operation. A positioning unit positions the flange to ensure operational accuracy. A drive unit moves the positioning unit relative to the flange, facilitating quick positioning and disassembly of the electromagnetic flowmeter. However, positioning requires a positioning shaft and the flange at the end of the electromagnetic flowmeter to work together. The positioning shaft is fixedly mounted on a positioning plate, resulting in poor compatibility with electromagnetic flowmeters of different diameters. When clamping larger diameter flowmeters, the distance between the positioning plate and the placement slot is insufficient, making clamping the flowmeter inconvenient. Furthermore, when adjusting the flowmeter's posture, due to the uneven mass distribution within the flowmeter, the heavier component tends to move towards the bottom. The positioning plate requires operator assistance to prevent the flowmeter from rotating and resetting the plate, hindering processing of the flowmeter. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a flow meter manufacturing assembly fixture. In this fixture, the clamping discs of each clamping mechanism are rotatably mounted on a support via a rotating shaft. A rotary drive is connected to the rotating shaft of one of the clamping discs via a worm gear mechanism, enabling the clamping discs to rotate. The sliding jaws allow adjustment of the dimensions of the resulting clamping portion, adapting to electromagnetic flow meters of different diameters. Furthermore, the distance between the clamping discs and the base can be adjusted using a lifting rod, providing ample space for the electromagnetic flow meter arrangement. The unidirectional transmission of the worm gear mechanism facilitates attitude adjustment of the electromagnetic flow meter without the need for auxiliary fixing. The worm gear mechanism provides self-locking position constraints, facilitating the processing of the electromagnetic flow meter and improving operational convenience and processing efficiency.

[0005] To achieve the above objectives, the following technical solution is adopted:

[0006] A flow meter manufacturing assembly fixture, comprising:

[0007] The base is equipped with a lead screw and slider mechanism, which has two sliders spaced apart and move in opposite directions along the lead screw axis when driven by the lead screw.

[0008] The clamping assembly includes two sets of clamping mechanisms arranged opposite to each other, each mounted on one of the two sliders. Each clamping mechanism includes a telescopic rod, a clamping disc, grippers, and a rotary drive. One end of the telescopic rod is fixed to the slider, and the other end is mounted on a support. The clamping disc is rotatably mounted on the support via a rotating shaft. Two grippers are slidably mounted on the side of the clamping disc facing the other set of clamping mechanisms, forming a clamping part between the grippers. The rotary drive is connected to the rotating shaft of one of the clamping discs via a worm gear mechanism to drive the clamping disc to rotate via the rotating shaft.

[0009] Furthermore, the clamping disk is equipped with a bidirectional telescopic component, and the two ends of the bidirectional telescopic component are respectively connected to grippers to drive the grippers installed on the same clamping disk to move closer or further away.

[0010] Furthermore, the gripper includes a mounting plate and a clamping plate. The mounting plate is attached to and slidably abuts against the end face of the clamping disk. The two ends of the mounting plate are respectively connected to clamping plates. All the clamping plates of the two grippers on the same clamping disk are arranged around the clamping part. The mounting plate is connected to the end of the bidirectional telescopic member through a movable block.

[0011] Furthermore, the clamping parts formed by the two sets of clamping mechanisms and the clamping disks are coaxially distributed, and the clamping parts, the rotating shaft and the clamping disks are coaxially distributed.

[0012] Furthermore, the rotary drive is mounted on the support, and a worm is connected to the output end of the rotary drive. The worm wheel is mounted on the rotating shaft, and the worm wheel cooperates with the worm.

[0013] Furthermore, one end of the rotating shaft is connected to the clamping disc, and the other end passes through the support and is connected to the worm gear.

[0014] Furthermore, the lead screw is rotatably mounted on the base, the base is provided with a sliding groove, the slider is threaded with the outer ring of the lead screw and slides with the sliding groove, and one end of the slider extends to the outside of the sliding groove to connect with the telescopic rod.

[0015] Furthermore, the outer ring of the lead screw is provided with two sections of threads with opposite directions of rotation, one of which is engaged with one section of the thread and the other is engaged with the other section of the thread.

[0016] Furthermore, the clamping disc is mounted above the base via a rotating shaft and a telescopic rod, with a gap between the bottom of the clamping disc and the top surface of the base.

[0017] Furthermore, the base is slidably fitted with a slide rail, which is arranged on the worktable.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are:

[0019] To address the issues of poor applicability and instability after attitude adjustment in current flow meter tooling equipment, the clamping mechanism in the clamping assembly features a clamping disc mounted on a support via a rotating shaft. A rotary drive is connected to the shaft of one of the clamping discs via a worm gear mechanism, enabling the clamping disc to rotate. The sliding jaws allow adjustment of the size of the resulting clamping portion, accommodating electromagnetic flow meters of different diameters. Furthermore, the lifting rod allows adjustment of the distance between the clamping disc and the base, providing ample space for the electromagnetic flow meter arrangement. The unidirectional transmission of the worm gear mechanism facilitates attitude adjustment of the electromagnetic flow meter without the need for auxiliary fixing. The worm gear mechanism provides self-locking position constraints, simplifying the machining operation of the electromagnetic flow meter and improving operational convenience and processing efficiency.

[0020] The screw-slider mechanism on the base enables two sliders to move in opposite directions along the screw axis, thereby adjusting the distance between the two sets of clamping mechanisms arranged oppositely to accommodate electromagnetic flowmeters with different axial lengths, thus improving the adaptability of the tooling to electromagnetic flowmeters of different specifications.

[0021] By installing a bidirectional telescopic component on the clamping plate, with clamps connected to both ends of the bidirectional telescopic component, the clamps on the same clamping plate can be driven to move closer or further away. The clamp spacing can be precisely adjusted according to the actual size of the electromagnetic flowmeter, achieving stable clamping of electromagnetic flowmeters of different sizes and improving the versatility and adaptability of the tooling.

[0022] The rotary drive is mounted on the support, and the output end is connected to the worm gear. The worm wheel is mounted on the rotating shaft and cooperates with the worm gear, so that the rotary drive can stably drive the clamping disk to rotate, realizing precise adjustment of the electromagnetic flowmeter's attitude. At the same time, the worm wheel and worm gear mechanism has a self-locking function, which can effectively prevent the electromagnetic flowmeter from rotating and resetting due to uneven mass distribution after the attitude is adjusted, thus facilitating processing operations.

[0030] In a typical embodiment of this utility model, such as Figures 1-5 As shown, a flow meter manufacturing assembly fixture is proposed.

[0031] Currently, in the production of electromagnetic flowmeters, the clamping fixtures are not convenient to adapt to different specifications of electromagnetic flowmeters, and it is also inconvenient to adjust and stabilize the posture of the electromagnetic flowmeter after clamping. Based on this, this embodiment provides a flowmeter production assembly fixture, which is equipped with a rotatable clamping plate 802. The clamping plate 802 has slidably mounted clamping jaws. The size of the clamping part can be changed by adjusting the distance between the jaws to adapt to electromagnetic flowmeters of different diameters. The clamping plate 802 is driven to rotate by a rotary drive 806 through a worm gear mechanism. The self-locking function of the worm gear mechanism is used to keep the clamping plate 802 and the electromagnetic flowmeter stable after adjusting their posture, thus meeting production requirements.

[0032] like Figure 1 As shown, the flow meter production assembly fixture includes a base 3, a lead screw and slider mechanism, and a clamping assembly. The base 3 serves as the basic support structure for the entire fixture, providing mounting positions for other components and ensuring the fixture's stability. The clamping assembly includes two sets of clamping mechanisms arranged opposite each other. Each clamping mechanism includes a telescopic rod 6, a clamping disc 802, grippers, and a rotary drive 806. One end of the telescopic rod 6 is fixed to the slider 403 via a base plate 5, and the other end is mounted on a support 7. The clamping disc 802 is rotatably mounted on the support 7 via a rotating shaft 801. Two grippers are slidably mounted on the side of the clamping disc 802 facing the other set of clamping mechanisms, forming a clamping section between the grippers. The rotary drive 806 is connected to the rotating shaft 801 of one of the clamping discs 802 via a worm gear mechanism, driving the clamping disc 802 to rotate via the rotating shaft 801.

[0033] The lead screw and slider mechanism is mounted on the base 3. The lead screw and slider mechanism has two sliders 403 that are spaced apart and move in opposite directions along the axis of the lead screw 402 when driven by the lead screw 402. The lead screw 402 provides driving force by rotating, so that the sliders 403 can move along their axis, thereby adjusting the distance between the two sets of clamping mechanisms.

[0034] The slider 403 is threaded with the outer ring of the lead screw 402. Driven by the lead screw 402, it moves in opposite directions along the axis of the lead screw 402, thereby driving the clamping mechanism mounted on it to move closer or further away to accommodate flow meters of different sizes.

[0035] One end of the telescopic rod 6 is connected to the slider 403, and the other end is fitted with a support 7 to support the clamping disc 802. The height of the clamping disc 802 can be adjusted as needed to accommodate flow meters of different heights. The clamping disc 802 is rotatably mounted on the support 7 via a rotating shaft 801, used to mount the grippers. It can also rotate around the rotating shaft 801 under the action of the rotary drive 806, thus adjusting the flow meter's attitude. The grippers are mounted on the clamping disc 802, forming a clamping section between the two grippers for clamping the flow meter. By sliding on the clamping disc 802, the clamping distance can be adjusted according to the flow meter's size, ensuring stable clamping of flow meters of different diameters.

[0036] The rotary drive component 806 is connected to the rotating shaft 801 of the clamping disk 802 via a worm gear mechanism, providing power for the rotation of the clamping disk 802 and enabling precise adjustment of the flowmeter's attitude. The worm gear mechanism transmits power from the rotary drive component 806 to the rotating shaft 801, driving the clamping disk 802 to rotate; simultaneously, it utilizes the self-locking characteristics of the worm gear 803 and worm 807 to prevent the flowmeter from rotating and resetting due to uneven mass distribution after the flowmeter's attitude has been adjusted.

[0037] like Figure 4 As shown, the bidirectional telescopic component 901 is mounted on the clamping disk 802, with clamping jaws connected to both ends. It can drive the clamping jaws on the same clamping disk 802 to move closer or further apart, thereby achieving precise clamping of flow meters of different sizes. The spacing of the clamping jaws is adjusted according to the outer diameter of the flow meter to ensure that the jaws can firmly grip the flow meter and prevent it from moving during assembly. The bidirectional telescopic component 901 can employ components such as a double-acting pneumatic cylinder or a double-acting hydraulic cylinder. By extending or shortening the bidirectional telescopic component 901, the clamping jaws connected to both ends move along a pre-set groove on the clamping disk 802, thus adjusting the clamping jaw spacing.

[0038] The gripper includes a mounting plate 903 and a clamping plate 904. The mounting plate 903 is attached to and slides against the end face of the clamping disk 802, serving as the mounting carrier for the clamping plate 904. At the same time, it is connected to the end of the bidirectional telescopic member 901 through the movable block 902. Driven by the bidirectional telescopic member 901, it slides on the clamping disk 802, ensuring that the clamping plate 904 can move accurately as the gripper spacing is adjusted to accommodate flow meters of different sizes.

[0039] like Figure 4 As shown, an installation cavity is provided on the clamping plate 802, and a sliding groove communicating with the installation cavity is provided on the end face of the clamping plate 802. The bidirectional telescopic member 901 is installed in the installation cavity, the movable block 902 slides with the sliding groove, and the sliding block protrudes out of the sliding groove to connect with the installation plate 903.

[0040] Clamping plates 904 are installed at both ends of the mounting plate 903, with all clamping plates 904 surrounding the clamping portion on the same clamping disc 802. The clamping plates 904 directly contact the electromagnetic flowmeter, increasing the contact area to improve clamping stability and reliability, and preventing the flowmeter from shaking or rotating during assembly. Figure 5 As shown, in order to prevent damage caused by collision when the clamping plate 904 comes into contact with the electromagnetic flowmeter, an anti-slip pad 905 is installed on the clamping plate 904. The anti-slip pad 905 can be made of rubber. On the one hand, it can prevent slippage and slippage during clamping, and on the other hand, it can reduce damage caused by collision or minor deformation defects caused by clamping force.

[0041] When the bidirectional telescopic component 901 drives the mounting plate 903 to slide on the clamping plate 802, the mounting plate 903 drives the clamping plate 904 to move synchronously, thereby adjusting the distance between the clamping plates 904 and realizing the clamping or loosening of the flow meter.

[0042] The two sets of clamping mechanisms are coaxially distributed with respect to the clamping portions formed by the clamping discs 802. Furthermore, the clamping portions, rotating shaft 801, and clamping discs 802 are coaxially distributed, ensuring that the flowmeter is centered when clamped. This results in uniform force on the flowmeter during attitude adjustment or other operations, leading to greater stability and improved assembly accuracy, avoiding assembly errors caused by flowmeter positional deviation. During the design and manufacture of the tooling, precise machining and assembly processes ensure the coaxiality of all components. During use, after the flowmeter is clamped, the coaxial distribution of the clamping portions causes the flowmeter's axis to coincide with the axis of the rotating shaft 801, ensuring the accuracy and stability of attitude adjustment.

[0043] The rotary drive component 806 is mounted on the support 7 and provides a power source for the rotation of the clamping disk 802. The rotary drive component 806 can be a stepper motor, servo motor, etc., and is connected to the worm gear 807 through the output shaft to transmit power to the worm gear 807, thereby driving the worm wheel 803 and the rotating shaft 801 to rotate, realizing the rotation of the clamping disk 802 and achieving the purpose of adjusting the attitude of the flow meter.

[0044] The worm gear 807, as an intermediate component for power transmission, transmits the rotational motion of the rotary drive 806 to the worm wheel 803. It is connected to the output shaft of the rotary drive 806 and meshes with the worm wheel 803, driving the worm wheel 803 to rotate through the interaction of their teeth. In this embodiment, fixed plates 805 are rotatably connected to both ends of the worm gear 807. The fixed plates 805 are arranged on the mounting bracket to form a rotational support for the worm gear 807. The mounting bracket is fixed to the support 7. Simultaneously, the rotary drive 806 can also be arranged on the mounting bracket. The worm wheel 803 is mounted on the rotating shaft 801 and cooperates with the worm gear 807. Driven by the worm gear 807, the worm wheel 803 drives the rotating shaft 801 to rotate, thereby causing the clamping disc 802 to rotate around the rotating shaft 801. The self-locking characteristic of the worm gear mechanism prevents the flowmeter from rotating back to its original position due to its own weight or other external forces after the flowmeter's attitude has been adjusted, ensuring the stability of its attitude.

[0045] When the rotary drive 806 is activated, its output shaft drives the worm gear 807 to rotate. The worm gear 807 meshes with the worm wheel 803, transmitting power to the worm wheel 803. The worm wheel 803 then drives the rotating shaft 801 and the clamping plate 802 to rotate, thereby adjusting the flow meter's attitude. After adjustment, due to the self-locking characteristic of the worm gear mechanism, the clamping plate 802 and the flow meter can maintain the adjusted attitude.

[0046] like Figure 2 As shown, one end of the rotating shaft 801 is connected to the clamping disk 802, and the other end passes through the support 7 and connects to the worm gear 803, serving as both the support shaft and the power transmission shaft for the rotation of the clamping disk 802. The rotating shaft 801 transmits the rotation of the worm gear 803 to the clamping disk 802, enabling the rotational movement of the clamping disk 802, while simultaneously supporting the clamping disk 802 to ensure its rotational stability and accuracy. When the worm gear 803 rotates under the drive of the worm 807, it drives the rotating shaft 801 to rotate via a key connection or other fixing method. The rotating shaft 801 then drives the clamping disk 802 to rotate around its axis, thereby achieving the adjustment of the flowmeter's attitude.

[0047] like Figure 2As shown, the lead screw 402 is rotatably mounted on the base 3, and its outer ring has two sections of threads with opposite directions of rotation. By rotating the lead screw 402, driving force is provided for the movement of the slider 403, thereby adjusting the distance between the two sets of clamping mechanisms to accommodate flow meters of different diameters. In this embodiment, one end of the lead screw 402 is connected to a pitch adjustment drive 401, which drives the lead screw 402 to rotate. The lead screw 402 is mounted on the base 3 via bearings. The pitch adjustment drive 401 can be a stepper motor, servo motor, etc.

[0048] The slider 403 is threaded into the outer ring of the lead screw 402 and slides into a groove on the base 3. Driven by the lead screw 402, the slider 403 moves in opposite directions along the axis of the lead screw 402 within the groove, thereby causing the clamping mechanism mounted on it to move closer to or away from the lead screw. One end of the slider 403 extends out of the groove and connects to the telescopic rod 6, transmitting the movement of the slider 403 to the clamping mechanism. When the lead screw 402 is rotated, due to the different directions of the two threads on the outer ring of the lead screw 402, the two sliders 403, which are engaged with the two threads, will move in opposite directions along the axis of the lead screw 402 under the action of the threads. The slider 403 slides within the groove, ensuring the direction and stability of its movement, while simultaneously driving the clamping mechanism to move through the connected telescopic rod 6, thus adapting to flow meters of different diameters.

[0049] like Figure 1 and Figure 3 As shown, the clamping disc 802 is mounted above the base 3 via a rotating shaft 801 and a telescopic rod 6. A gap is left between the bottom of the clamping disc 802 and the top surface of the base 3 to prevent interference between the clamping disc 802 and the base 3 during rotation. This provides sufficient space for the rotation of the clamping disc 802 and also facilitates cleaning and maintenance of the tooling. During use, when the clamping disc 802 rotates, it will not contact the base 3 due to the gap, ensuring smooth rotation.

[0050] The base 3 is slidably fitted with a slide rail 2, which is arranged on the worktable 1, allowing the tooling to move flexibly on the worktable 1. This facilitates switching between different workstations, improving the efficiency and flexibility of production assembly, and also makes it easy to adjust and arrange the tooling according to actual production needs.

[0051] The base 3 is equipped with a sliding groove structure that mates with the slide rail 2. When the tooling needs to be moved, the base 3 slides on the slide rail 2 to adjust the position of the tooling. After movement, the position is locked by a locking device, which can be a positioning pin, a positioning bolt, or a positioning screw hole.

[0052] This invention solves the problems of inaccurate and unstable clamping of flow meters of different sizes caused by traditional clamps. Through the bidirectional telescopic component 901 and adjustable grippers, it can adapt to the clamping requirements of flow meters of different diameters. It overcomes the assembly error problem caused by misalignment of the clamping parts. The coaxial distribution of the clamping part, rotating shaft 801, and clamping plate 802 ensures the positional accuracy of the flow meter during assembly. It avoids operational difficulties caused by unstable power transmission or inability to lock the attitude when adjusting the flow meter's posture. Through the cooperation of the rotary drive component 806, the worm gear mechanism, and the rotating shaft 801, precise adjustment and locking of the attitude are achieved.

[0053] During operation, firstly, according to the diameter of the flow meter to be assembled, the lead screw 402 is rotated. The lead screw 402 drives the slider 403 to move in opposite directions along the axis of the lead screw 402 within the slide groove, thereby causing the two sets of clamping mechanisms to move closer or further apart, so that the distance between the jaws adapts to the size of the flow meter. Then, the flow meter is placed in the clamping part between the two sets of jaws, and the jaws are driven by the bidirectional telescopic component 901 to clamp the flow meter.

[0054] If the flow meter's attitude needs to be adjusted, the rotary drive 806 is activated. The rotary drive 806 drives the rotating shaft 801 to rotate via a worm gear mechanism, which in turn causes the clamping plate 802 to rotate around the rotating shaft 801, thus adjusting the flow meter's attitude. After adjustment, due to the self-locking characteristic of the worm gear mechanism, the flow meter can maintain the adjusted attitude.

[0055] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
