Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic flowmeter processing, in particular to a sandblasting device used for an electromagnetic flowmeter. Background Art

[0002] The electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow rate of conductive fluid based on the electromotive force induced when the conductive fluid passes through an external magnetic field. It is mainly composed of a casing, a magnetic circuit system, a measuring conduit, electrodes, a casing, a lining and a converter.

[0003] During the production and processing of electromagnetic flowmeters, sand is sprayed on the outer shell through sandblasting equipment. At present, when the sandblasting equipment sprays the outer shell of the electromagnetic flowmeter, the electromagnetic flowmeter outer shell is placed in a sealed box. After the nozzle sprays one side of the electromagnetic flowmeter outer shell, the operator manually flips it over and uses the nozzle to spray the outer shell of the electromagnetic flowmeter again. This processing method makes the sandblasting equipment only able to spray one electromagnetic flowmeter outer shell at a time, which is time-consuming and labor-intensive when facing multiple electromagnetic flowmeters. The electromagnetic flowmeter outer shell needs to be manually flipped when sandblasting in the whole area, which makes it difficult to spray the paint on the electromagnetic flowmeter outer shell evenly, which not only increases the operator's workload, but also affects the efficiency of sandblasting the electromagnetic flowmeter outer shell. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the shell of the electromagnetic flowmeter is directly placed in the sandblasting equipment, which makes it difficult to spray the sand material evenly, and proposes a sandblasting device for the electromagnetic flowmeter.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 5 A sandblasting device for an electromagnetic flowmeter comprises a processing table 1, a sand storage box, and a sandblasting port 2. A frame 3 and a sealing seat 4 are fixedly installed in the processing table 1, and three evenly distributed rotating shafts 7 are rotatably installed in the frame 3. It is supplemented that the sand in the sand storage box is ejected through the sandblasting port 2, which is a prior art;

[0023] Supplementary explanation: the length of the frame 3 is adjusted according to the specifications of the processing table 1, so that the number of the rotating shafts 7 can be adjusted according to the specifications of the frame 3, so that the processing table 1 can perform synchronous sandblasting on multiple flow meter housings;

[0024] A clamping plate 8 and a positioning rod 9 corresponding to the flow meter housing are fixedly mounted on the rotating shaft 7, and the rotating shaft 7 and the driven rod 10 are arranged horizontally corresponding to each other, and the clamping plate 8 and the rotating shaft 7 extend to one side outside the frame 3;

[0025] A hydraulic cylinder 5 is fixedly installed in the sealing seat 4, and a support plate 6 is fixedly installed at the output end of the hydraulic cylinder 5. A sealing door is installed on a pin shaft on one side of the processing table 1, and the frame 3 is vertically arranged corresponding to the support plate 6. Three evenly distributed driven rods 10 are rotatably installed on the support plate 6, and a clamping plate 2 11 and a positioning rod 2 12 corresponding to the flow meter housing are respectively fixedly installed on the driven rod 10. When the center hole of the flow meter housing corresponds to the positioning rod 1 9, the left side of the flow meter housing is movably opposed to the clamping plate 1 8, and when the hydraulic cylinder 5 drives the support plate 6 to move, the positioning rod 2 12 is extended to the center hole of the flow meter housing and is movably opposed to the positioning rod 1 9, so that the two sides of the flow meter housing correspond to the clamping plate 1 8 and the clamping plate 2 11, respectively, thereby limiting the flow meter housing;

[0026] A frame useful for collecting the coating is placed on the processing table 1. The positioning rod 1 9 and the positioning rod 2 12 are cylindrical structures adapted to the center hole of the flow meter housing. The positioning rod 1 9 and the positioning rod 2 12 are both provided with rubber convex strips 13 corresponding to the center hole of the flow meter housing. The rubber convex strips 13 can increase the friction between the clamping plate 1 8, the clamping plate 2 11 and the center hole of the flow meter housing, so that the positioning rod 1 9 can transmit power to the flow meter housing when rotating, so that the flow meter housing can drive the positioning rod 2 12 and the driven rod 10 to rotate synchronously;

[0027] A reinforcement component for reinforcing the housing of the flow meter is installed on the positioning rod 2 12;

[0028] The reinforcement assembly includes a reinforcement plate 14 fixedly mounted on the second clamping plate 11, and a reinforcement rod 15 extending to the connection ear of the flow meter housing is fixedly mounted on the reinforcement plate 14, and the reinforcement rod 15 extends to the connection ear of the flow meter housing, so that when the flow meter housing rotates, the second clamping plate 11 can also be driven to rotate through the reinforcement rod 15 and the reinforcement plate 14;

[0029] A rotating assembly for driving the rotating shaft 7 is installed on the frame 3;

[0030] The rotating assembly includes a gear 16 fixedly mounted on the rotating shaft 7, a guide rod 17 fixedly mounted on the frame 3, and a rack 18 meshingly connected to the three gears 16 is slidably sleeved on the guide rod 17, and a cylinder 19 connected to the rack 18 is fixedly mounted on the frame 3. The rack 18 can be lifted and moved by extending and retracting the output end of the cylinder 19, so that the flow meter housing can be rotated in the processing table 1, which not only eliminates the need for the operator to manually flip the flow meter housing, but also enables the sand material to be evenly sprayed on the flow meter housing during spraying, thereby improving the efficiency of sandblasting the flow meter housing;

[0031] It should be noted that the specific models and specifications of the sand storage box, the sandblasting port 2, the hydraulic cylinder 5, and the air cylinder 19 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0032] The functional principle of the utility model can be explained through the following operation modes:

[0033] Lift the flow meter housing and place the flow meter housing on one of the positioning rods 9 so that the positioning rod 9 can correspond to the center hole of the flow meter housing;

[0034] When the left side of the flow meter housing is movably against the clamping plate 8, the positioning rod 9 and the rubber convex strip 13 can limit the flow meter housing;

[0035] Repeat the above steps to allow another flow meter housing to be sleeved on another positioning rod 9;

[0036] The output end of the hydraulic cylinder 5 is extended and retracted to drive the support plate 6 to slide in the sealing seat 4. When the support plate 6 moves, it drives the three driven rods 10 and the second positioning rod 12 to move synchronously. When the positioning rod 12 moves, it can extend into the center hole of the flow meter housing and move against the positioning rod 1 9. At the same time, the support plate 6 drives the second clamping plate 11 to move against the right side of the flow meter housing. When the clamping plate 11 moves, it drives the reinforcement plate 14 and the reinforcement rod 15 to move, so that the reinforcement rod 15 can extend into the connecting ear of the flow meter housing.

[0037] When the three flow meter housings are limited, the output end of the cylinder 19 is extended and retracted to drive the rack 18 to slide on the guide rod 17. When the rack 18 moves, it is meshed and connected with the three gears 16, so that the gears 16 drive the three shafts 7 to rotate, and the shaft 7 drives the positioning rod 1 9, the flow meter housing, the positioning rod 2 12, and the driven rod 10 to rotate;

[0038] The paint in the sand storage box is sprayed out through the sand blasting port 2 and sprays the flow meter housing;

[0039] When the flow meter housing is sprayed, the sealing door is pulled to deflect and the processing table 1 is opened, and the hydraulic cylinder 5 drives the support plate 6 and the positioning rod 12 back to the initial position, and the flow meter housing is taken out.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
