Technical Field

[0001] This utility model relates to a vertical aluminum shell explosion-proof testing fixture. Background Technology

[0002] With market development, the demand for products with explosion-proof valve aluminum shells is increasing. Existing explosion-proof pressure testing fixtures are mostly horizontal fixtures. The top cover of these horizontal fixtures can be easily removed, resulting in poor sealing. This allows workshop debris and dust to easily enter the equipment and flow into the oil pump. Consequently, the oil pump needs to be disassembled and cleaned periodically; otherwise, it will affect the normal operation of the oil pump. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a vertical aluminum shell explosion-proof testing fixture. This fixture uses a sealing component to enclose and seal the test location, resulting in good overall sealing and reducing the entry of debris and dust.

[0023] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0024] like Figure 1-7 As shown, a vertical aluminum shell explosion-proof testing fixture includes a pressure-measuring aluminum shell 23, an upper fixing plate 1, a lower fixing plate 2, and a base plate 3. The upper fixing plate 1 and the lower fixing plate 2 are connected and fixed by a first support rod 201, and the lower fixing plate 2 and the base plate 3 are connected and fixed by a second support rod 301. An oil pump 32 is mounted on the base plate 3 and fixed by an oil pump fixing column 33.

[0025] A sealing assembly is installed on the lower fixing plate 2, and the pressure measuring aluminum shell 23 is installed inside the sealing assembly;

[0026] A top material assembly is installed on the upper fixing plate 1, and the functional end of the top material assembly is connected to the upper end of the sealing assembly.

[0027] A pressure gauge 11 is installed on the upper fixed plate 1. The pressure gauge 11 is connected to the oil pump and the sealing assembly through the oil pressure pipeline. An oil pump switch 31 is installed on the base plate 3.

[0028] Furthermore, the upper end of the oil pump 32 is a pump station connection block 321, and the pump station connection block 321 has an oil pump connector that communicates with the inside of the oil pump 32. The oil pump fixing column 33 is vertically set on the base plate 3 on both sides of the oil pump 32, and the upper end of the oil pump fixing column 33 is connected and fixed to the pump station connection block 321.

[0029] Furthermore, the sealing assembly includes an oil pan 25, a pad 24, an explosion-proof fixed baffle 21, and an explosion-proof movable baffle 22 fixed on the lower fixed plate 2. The lower fixed plate 2 has a clearance hole 251, and the oil pan 25 has a nut connector 241 corresponding to the clearance hole 251. The pad 24 is installed in the middle of the oil pan 25. The upper end of the nut connector 241 passes through the pad 24, and the lower end of the nut connector 241 passes through the clearance hole 251. The pressure-measuring aluminum shell 23 is installed on the pad 24 and covers the nut connector 241. The explosion-proof fixed baffle 21 and the explosion-proof movable baffle 22 are inserted into the edge of the oil pan 25 to cover and seal the pressure-measuring aluminum shell 23. The pressure-measuring aluminum shell is stably installed by the pad 24, and the explosion-proof fixed baffle 21 and the explosion-proof movable baffle 22 seal the interior to prevent dust from entering.

[0030] Furthermore, both the explosion-proof fixed baffle 21 and the explosion-proof movable baffle 22 are cylindrical with openings at the top and bottom, and both have notches on their surfaces. The diameter of the explosion-proof fixed baffle 21 is slightly larger than that of the explosion-proof movable baffle 22, and the two together form a cylinder to seal the pressure measuring aluminum shell 23. The explosion-proof movable baffle 22 can rotate along the edge of the oil pan 25 to open or close the notch.

[0031] Furthermore, the top-feeding assembly includes a handwheel 101, a lead screw 102, an explosion-proof baffle cover 104, and a top-feeding block 105. The lead screw 102 is connected to the middle of the upper fixed plate 1 via a flange 103 and passes downward through the upper fixed plate 1. The handwheel 101 is connected to the upper end of the lead screw 102. A connecting block 106 is connected to the lower end of the lead screw 102. A bearing 107 is sleeved on the lead screw 102 within the connecting block. The top-feeding block 105 is connected and fixed to the lead screw 102 via a bearing stop 108. The explosion-proof baffle cover 104 is disposed on the lead screw 102 and covers the upper ends of the explosion-proof fixed baffle 21 and the explosion-proof movable baffle 22. The lower end of the top-feeding block 105 can abut against the pressure-measuring aluminum shell 23. Rotating the handwheel 101 rotates the lead screw 102, causing the lead screw 102 to feed downward, thereby pressing the top-feeding block 105 against the pressure-measuring aluminum shell 23.

[0032] Furthermore, the upper end of the bearing stop 108 is provided with a connecting edge 1081 that is fixed to the end of the lead screw 102, the inside of the top material block 105 has a pressure step 1051, and the lower edge of the bearing stop 108 is provided with a pressing step 1082 that presses against the pressure step 1051.

[0033] In the above structure, the top material block 105 is fixed to the lower end of the lead screw 102 by means of bearing stop 108 and by means of extrusion step 1082 and pressure step 1051.

[0034] Furthermore, the hydraulic pipeline includes a first oil pipe 111 connecting the pressure gauge 11 to the oil pump connector and a second oil pipe 112 connecting the pressure gauge 11 to the nut connector 241.

[0035] Principle: Place the pressure testing aluminum shell 2323 with its opening facing down into the support block 24. Turning the handwheel 101 rotates the lead screw 102, causing the top block 105 to press down and contact the upper end of the pressure testing aluminum shell 2323, thus tightening it. Then, rotate the explosion-proof movable baffle 22 to cover the notch and form a cylindrical sealing structure with the explosion-proof fixed baffle 21. Set the pressure gauge 11 to the required pressure value. Press the oil pump switch 31 to start the oil pump 32. The oil in the oil pump 32 flows into the pressure gauge 11 through the first oil pipe 111, and then flows into the pressure testing aluminum shell 2323 through the second oil pipe 112 and the nut connector 241, thus opening the product. At this time, the pressure gauge 11 displays the required pressure value.

[0036] This fixture mainly consists of a fixed explosion-proof baffle 21 and a movable explosion-proof baffle 22 forming a cylindrical sealing structure to reduce the entry of garbage and dust.
