[0004] In the prior art, including the aforementioned patent, the inner wall of the vortex flow meter housing needs to be polished after production to ensure that there are no protrusions on the inner wall of the housing that interfere with the flow of water. Currently, most of the polishing is done manually by workers. However, during manual polishing, the degree of polishing on different parts of the inner wall is not the same, which makes it difficult to keep the inner wall of the housing in a perfect circle, which is not conducive to the subsequent production process of the flow meter.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-3As shown, a vortex flowmeter housing grinding device includes a base 1, on which a fixed seat 11 and a movable seat 12 are respectively provided. The fixed seat 11 is movably provided with a plurality of clamping rods 111 for clamping workpieces. The movable seat 12 is rotatably provided with a mounting plate 121 concentric with the workpieces clamped by the plurality of clamping rods 111. The mounting plate 121 is movably provided with a plurality of grinding rods 122. The plurality of clamping rods 111 move synchronously to clamp the workpieces, and the clamping rods 111 drive the plurality of grinding rods 122 to move synchronously, and the outer edge of the grinding rods 122 is tangent to the inner wall of the workpiece.

[0025] Specifically, the movable base 12 is equipped with a motor that is self-locking when power is off, and the mounting plate 121 is fixedly installed on the output end of the motor.

[0026] Furthermore, in the above embodiments, the workpiece is specifically the housing of a vortex flow meter, and the grinding rod 122 is specifically a metal rod with a wire brush on it.

[0027] In the above technical solution, during the grinding operation, the workpiece is placed in the through hole on the fixed seat 11, and the clamping rod 111 is driven to move. Multiple clamping rods 111 move synchronously and abut against the outer wall of the workpiece. The workpiece, the fixed seat 11, and the mounting plate 121 are all concentric. The clamping rod 111 drives multiple grinding rods 122 to move synchronously, so that the outer edge of the grinding rod 122 is tangent to the inner wall of the workpiece. At this time, the operator pushes the movable seat 12, so that the grinding rod 122 extends into the workpiece. The motor outputs torque to drive the mounting plate 121 to rotate. The mounting plate 121 drives the grinding rod 122 to rotate to grind the inner wall of the workpiece. Pushing the movable seat 12 allows the grinding rod 122 to reciprocate to grind the inner wall of the workpiece, ensuring that there are no protrusions on the inner wall of the workpiece and that the inner wall of the workpiece remains perfectly round.

[0028] As a further embodiment of this utility model, the bottom of the movable seat 12 is provided with a first tenon 123, and the base 1 is provided with a mortise that matches the first tenon 123.

[0029] Specifically, the first tenon 123 engages with the tenon groove on the base 1, restricting the movement direction of the movable seat 12, so that the mounting plate 121 always remains concentric with the workpiece, making it convenient for the mounting plate 121 to drive the grinding rod 122 to move and grind the inner wall of the workpiece.

[0030] As a further embodiment of this utility model, the fixed base 11 is rotatably provided with a first drive ring 112 for driving multiple clamping rods 111 to move synchronously. The first drive ring 112 is provided with a first planar thread, and the clamping rods 111 are provided with a sliding groove adapted to the first planar thread.

[0031] Specifically, the first drive ring 112 is provided with a rocker arm 126 extending to the outside of the fixed base 11.

[0032] Furthermore, when fixing the workpiece, the workpiece is placed in the through hole on the fixed seat 11, and the rocker arm 126 is manually pushed to rotate the first drive ring 112. The first planar thread on the first drive ring 112 moves along the sliding groove on the clamping rod 111, pushing the clamping rod 111 closer to the center of the fixed seat 11 and gradually abutting against the outer wall of the workpiece. Multiple clamping rods 111 abut against the outer wall of the workpiece at the same time, fixing the workpiece on the fixed seat 11, which facilitates the grinding work.

[0033] As another embodiment further provided by this utility model, a second drive ring 124 is rotatably provided on the mounting plate 121 for driving multiple grinding rods 122 to move synchronously. A second tenon 125 is provided on the grinding rod 122 and extends into the mounting plate 121. A tenon groove adapted to the second tenon 125 is provided on the mounting plate 121. A second planar thread is provided on the second drive ring 124. A sliding groove adapted to the second planar thread is provided on the second tenon 125.

[0034] Specifically, while the first drive ring 112 rotates, the second drive ring 124 rotates. The second planar thread on the second drive ring 124 moves along the groove on the second tenon 125 and pushes the second tenon 125 along the tenon groove on the mounting plate 121 toward the center of the mounting plate 121 until the clamping rod 111 abuts against the outer wall of the workpiece. At this time, the outer edge of the grinding rod 122 on the second tenon 125 is tangent to the inner wall of the workpiece.

[0035] As another embodiment further provided by this utility model, a shaft 13 is rotatably provided inside the base 1, and a first gear 131 and a second gear 132 are respectively provided at both ends of the shaft 13. The side wall of the first drive ring 112 is provided with gear teeth that mesh with the first gear 131, and the side wall of the second drive ring 124 is provided with gear teeth that mesh with the second gear 132.

[0036] Specifically, during the process of manually pushing the rocker arm 126 to drive the first drive ring 112 to rotate, the gear teeth on the side wall of the first drive ring 112 drive the first gear 131 to rotate, which in turn drives the second gear 132 to rotate via the shaft 13. The second gear 132 drives the second drive ring 124 to rotate via the gear teeth that mesh with it, causing the grinding rod 122 to move until the clamping rod 111 abuts against the outer wall of the workpiece. At this time, the outer edge of the grinding rod 122 on the second tenon 125 is tangent to the inner wall of the workpiece. At this time, the movable seat 12 can be pushed to separate the second gear 132 from the second drive ring 124. At this time, the motor can drive the mounting plate 121 to rotate, so that the grinding rod 122 grinds the inner wall of the workpiece.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
