Description

Technical Field

[0001] The utility model belongs to the technical field of flow meter production equipment and relates to a flow meter impeller assembly tool. Background Art

[0002] The flow meter is mainly composed of Hall elements, magnetic materials and plastic structural parts. When the impeller is driven to rotate by the directional water flow, the magnet inside the impeller senses the Hall element and outputs a pulse signal. The number of pulse signals generated by the speed of the impeller rotation frequency is converted into the water output per unit time. Figure 1 As shown, it includes an impeller body a, a magnet b installed in the impeller body a, and a cap c for realizing the magnet b, and the cap c is installed on the top of the impeller body a through interference fit. Therefore, when assembling the impeller, the worker needs to place the cap c on the top of the impeller body a, and then press or hammer it hard to complete the installation of the cap c. However, since the impeller body a, especially the cap c, is extremely small, it is very time-consuming and laborious to manually assemble it by workers. At the same time, since the downward pressure is difficult to control, it is easy to cause unnecessary damage. Utility Model Content

[0003] The purpose of the utility model is to provide a flow meter impeller assembly tool to solve the above problems in the existing technology, so as to assist workers in assembling the flow meter impeller, thereby improving production efficiency.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a flow meter impeller assembly tool, characterized in that the tool comprises a base, a support plate and a positioning seat are fixed on the upper surface of the base; a vertical slide rail is fixed on a side wall of the support plate, a slider is slidably connected to the slide rail, an adsorption block is fixed on the slider, an adsorption head is fixed to the bottom of the adsorption block, and an adsorption groove opening downward is provided at the bottom of the adsorption head; a negative pressure pipe is provided on the adsorption block, and the negative pressure pipe is connected to the top of the adsorption groove; a mounting plate is fixed on the top of the support plate, a cylinder is fixed on the mounting plate, and the cylinder can drive the adsorption block to slide up and down; a positioning groove is provided on the top of the positioning seat just below the adsorption head.

[0006] The utility model has the advantages:

[0007] 1. This tooling uses a suction head with negative pressure to achieve fixed clamping of the cap which is small in size and difficult to grasp, greatly improving the assembly efficiency of the impeller.

[0008] 2. This tooling adopts a cylinder to realize the pressing installation of the cover cap, which not only saves time and labor, but also further improves production efficiency.

[0009] 3. This tooling uses adjusting parts to connect the push rod and adsorption block of the cylinder respectively, and the thread directions at both ends are opposite.

DETAILED DESCRIPTION

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 2 and Figure 3 As shown, a flow meter impeller assembly tool comprises a base 1, a support plate 2 and a positioning seat 3 are fixed on the upper surface of the base 1; a vertical slide rail 21 is fixed on one side wall of the support plate 2, a slider 4 is slidably connected to the slide rail 21, an adsorption block 41 is fixed on the slider 4, an adsorption head 42 is fixed to the bottom of the adsorption block 41, and an adsorption groove with an opening downward is provided at the bottom of the adsorption head 42; a negative pressure pipe 43 is provided on the adsorption block 41, and the negative pressure pipe 43 is connected to the top of the adsorption groove; a mounting plate 5 is fixed on the top of the support plate 2, a cylinder 6 is fixed on the mounting plate 5, and the cylinder 6 can drive the adsorption block 41 to slide up and down; a positioning groove 31 is provided on the top of the positioning seat 3 just below the adsorption head 42.

[0016] Working principle: When this tool is working, the negative pressure pipe 43 needs to be connected to the exhaust pipe so that there is always airflow in the adsorption tank. We can first place the impeller body a with the permanent magnet b installed in the positioning groove 31 at the top of the positioning seat 3, and the inner diameter of the bottom of the positioning groove 31 just fits the outer diameter of the positioning groove 31, so it can realize the positioning of the impeller body a; then place the cap c under the adsorption head 42, and under the action of the continuous airflow inside, the cap c will be adsorbed in the adsorption tank. Then start the cylinder 6, its push rod extends outward, driving the slider 4 downward, and then buckling the cap c on the top of the impeller body a to complete the installation of the impeller.

[0017] The tooling adopts a suction head 42 with negative pressure to achieve fixed clamping of the cap c which is small in size and difficult to grasp, greatly improving the assembly efficiency of the impeller. The cylinder 6 is used to realize the pressing installation of the cap c, which not only saves time and effort, but also further improves production efficiency.

[0018] like Figure 2 and Figure 3 As shown, an adjusting member 7 is provided between the push rod of the cylinder 6 and the adsorption block 41, a screw hole is provided at the top of the adjusting member 7, and a screw 71 is fixed at the lower end of the adjusting member 7; the screw hole and the push rod of the cylinder 6, and the screw 71 and the adsorption block 41 are all threadedly connected, and the screw hole and the screw 71 have opposite thread directions, and the push rod of the cylinder 6 and the screw 71 are both provided with a locking nut 72. The two ends of the adjusting member 7 are respectively threadedly connected to the push rod of the cylinder 6 and the adsorption block 41, and the thread directions of the two ends are opposite, so we can achieve the lowest position of the adsorption block 41 by rotating the cover link, thereby avoiding damage to the cover cap c due to excessive downward pressure during installation, and improving the assembly yield rate. The locking nut 72 is used for locking after adjustment.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
