Description

Technical Field

[0001] The utility model belongs to the field of reverse osmosis membrane element detection equipment, and particularly relates to a polysulfone end cover outer diameter detection tool. Background Art

[0002] As an environmentally friendly and efficient water treatment technology, RO (reverse osmosis) technology can complete the water treatment process with minimal resource consumption. It has been widely used in industrial wastewater treatment and domestic drinking water production. With the continuous advancement of technology, reverse osmosis membrane elements are gradually being applied to the treatment of high-temperature and corrosive industrial wastewater. These elements are typically made of polysulfone material for the end caps. Polysulfone has excellent properties such as excellent heat resistance, corrosion resistance, and mechanical strength, but it is relatively expensive. Therefore, the requirements for testing standards have been correspondingly strengthened to reduce the impact of defective products on the cost of use.

[0003] During the manufacturing process of polysulfone end caps, the outer diameter of the end caps is a critical parameter, directly affecting the product's assembly process and final product performance. Therefore, the outer diameter of the end caps must be 100% inspected during the manufacturing process to ensure that each end cap meets the standards. Current inspection methods rely on manual labor, using handheld calipers to measure the dimensions of the end caps. However, in actual measurements, the angle of operation can easily lead to inflated test results. Furthermore, polysulfone, as a plastic, has a certain degree of toughness and relatively low hardness. When subjected to large forces, it easily deforms, causing deviations in the test results. Both of these factors can lead to errors in the test results, resulting in defective products entering the application scenario, increasing user costs while also affecting the manufacturer's reputation. Traditional inspection methods often fail to meet the requirements for efficient and accurate testing. Therefore, designing a dedicated inspection tool to improve detection accuracy and ease of operation has become an urgent issue to be addressed. Utility Model Content

[0004] The utility model provides a polysulfone end cap outer diameter inspection tool, including a base plate, side plates, baffles and inspection parts. The side plates and baffles are vertically connected to the side edges of the base plate. When connected, the side plates and baffles are located on adjacent edges. The side edges and baffles can provide two vertical fulcrums for the polysulfone end cap, pre-fixing the position of the polysulfone end cap from two directions. In order to realize the function, the inspection part is composed of a guide rail, a slider, a dial base and a digital dial indicator. The slider is mounted on the guide rail in a slidable manner, and then the dial base is mounted on the slider. The digital dial indicator is mounted on the dial base as a measuring component. Two slide grooves are opened on the end face of the base plate. The two slide grooves are parallel to each other and perpendicular to the baffle. The two points of the guide rail are respectively mounted on the two slide grooves in a slidable manner so that the guide rail is parallel to the baffle. The outer diameter of the polysulfone end cap can be measured by a digital dial indicator. At the same time, the position of the guide rail on the slide and the position of the slider on the guide rail can be adjusted, and the distance and position of the digital dial indicator relative to the baffle can be moved to adapt to the detection of polysulfone end caps of different sizes.

[0005] Since polysulfone end caps have different shapes and sizes, the outer diameters of the polysulfone end caps that need to be measured are different. In order to perform accurate measurements, a movable reference block is set on the side of the baffle facing the guide rail. The reference block is installed by opening two vertical slots on the baffle so that the two vertical slots are parallel to each other, and then opening two screw holes on the side of the reference block close to the baffle. The positions of the screw holes correspond to the positions of the vertical slots, and then butterfly screws are passed through the vertical slots to install them on the screw holes. The reference block is connected to the baffle by the butterfly screws. The reference block can move up and down along the vertical slots and then fixed in position by the butterfly screws.

[0006] In order to cooperate with the movable reference block to measure the outer diameter of polysulfone end covers of different heights, a vertical slot is set on the base, and a connecting block is installed in the slot. A clamping block is provided on the side of the connecting block, and the connecting block can be moved up and down in the slot through the clamping block. Then a fixing screw is installed on the side of the clamping block. The head diameter of the fixing screw is larger than the width of the slot. The connecting block can be fixed to the base through the fixing screw, and the digital dial indicator is installed on the connecting block to realize the height adjustment of the digital dial indicator.

[0007] In order to better adjust the connecting block and limit it to remain horizontal, the width of the card block is consistent with the width of the slot and inserted into the slot. In this way, the angle of the card block will be firmly fixed by the slot, so that the connecting block always maintains a horizontal angle.

[0008] As the best way to install the guide rail, two bolt holes are opened on the guide rail, and their positions correspond to the two slide grooves respectively. An avoidance groove is set at the lower end of the slide groove. The fixing bolt is inserted from above the bolt hole, and the end of the fixing bolt is inserted into the avoidance groove. A fixing nut is put on the end of the fixing bolt. By adjusting the tightness of the fixing bolt, the guide rail position can be released and fixed.

[0009] The polysulfone end cap outer diameter gauge provided by the utility model is designed with ease of operation in mind, avoiding the problem of inaccurate measurements caused by inconvenient operation and human errors when using calipers for detection, and greatly improving the repeatability and reliability of the detection. It can effectively avoid the deformation of plastic products when subjected to force, making the detection results more accurate, greatly reducing errors, and ensuring the accurate measurement of the outer diameter dimensions of the end caps of reverse osmosis membrane elements. The device has a simple structure and is easy to use, which can significantly reduce the workload of operators. By simplifying the operating process, the possibility of errors is reduced and the detection efficiency is improved. The detection process is simplified and the detection speed is accelerated, thereby greatly improving the overall detection efficiency, and is suitable for high-frequency detection of reverse osmosis membrane elements in large-scale production processes. By improving detection accuracy and reducing scrap rates, the utility model indirectly reduces production costs and improves economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] To further illustrate the concept of the present invention, the following will further describe the specific implementation of the present invention with reference to the accompanying drawings:

[0019] A polysulfone end cap outer diameter gauge, such as Figure 2As shown, the apparatus comprises four parts: a bottom plate 1, a side plate 2, a baffle 3, and a detection member 4. The bottom plate 1, side plate 2, and baffle 3 are two rectangular plates. The baffle 3 is vertically mounted on the right side of the bottom plate 1, and the side plate 2 is vertically mounted on the rear side of the bottom plate 1. Two chute grooves 9 are opened in the bottom plate 1 in a direction parallel to the side plate 2, and the bottom half of the chute grooves 9 is widened to form an avoidance groove 19.

[0020] Take a long block as the reference block 10, open a screw hole at each end of the reference block 10, and then open two vertical slots 11 on the baffle 3 at the positions corresponding to the two screw holes. Make the reference block 10 located on the inside of the baffle 3 and attached to the side wall, so that the screw hole positions correspond to the vertical slots 11. Install the butterfly screws 12 from the outside of the baffle 3 into the screw holes, and tighten the butterfly screws 12 to fix the reference block 10 on the baffle 3. Figure 6 shown.

[0021] Take a guide rail 5 with a slider 6, and make two stepped holes on the guide rail 5 at a distance equivalent to the distance between the two slide grooves 9 as bolt holes 17. Place the guide rail 5 on the bottom so that the two bolt holes 17 correspond to the two slide grooves 9 respectively, and then put the fixing bolts 18 into the bolt holes 17. Put the fixing nuts 20 on the ends of the fixing bolts 18 from the direction of the avoidance groove 19, and tighten the fixing nuts 20 to fix the guide rail 5 on the base plate 1. Figure 3 、 Figure 5 shown.

[0022] An L-shaped plate is installed on the left side of the slider 6 as a table base 7, so that the two sides of the table base 7 are perpendicular to the horizontal line and parallel to the baffle 3 and the side plate 2 respectively. A vertical slot 14 is opened on the side of the table base 7 parallel to the side plate 2. A rectangular block is taken as a connecting block 13, and a clamping block 15 is milled on the front side of the connecting block 13. The width of the clamping block 15 is consistent with the width of the slot 14, and then a screw hole is opened on the clamping block 15. The clamping block 15 is inserted into the slot 14, and then a fixing screw 16 is installed on the screw hole. Tighten the fixing screw 16 to fix the position of the clamping block 15, as shown in FIG. Figure 4 As shown, a digital dial indicator 8 is installed on the connecting block 13, and the measuring end of the digital dial indicator 8 is directed toward the baffle 3 to obtain the detection part 4.

[0023] When testing, first loosen the fixing bolt 18, move the guide rail 5 to the leftmost side of the slide 9, then place the polysulfone end cap on the base plate 1, and loosen the butterfly screw 12 at the same time. Adjust the position of the reference block 10 so that the reference block 10 is at the test height and then tighten the butterfly screw 12. Adjust the polysulfone end cap to contact the reference block 10 and the base plate 1 respectively, loosen the fixing screw 16 and adjust the position of the connecting block 13 so that the digital dial indicator 8 is at the test height and then tighten the fixing screw 16. Move the guide rail 5 left and right so that the digital dial indicator 8 contacts the highest point of the measured outer diameter and pre-load it by about 1mm. Then tighten the fixing bolt 18 and fix the guide rail 5. After returning the digital dial indicator 8 to zero, the calibration of the inspection tool is completed. Fit one end of the polysulfone end cap to the reference block 10, as shown in the figure. Figure 1 As shown, the digital display dial indicator 8 can be slided back and forth by the slider 6 to find the extreme value to determine whether the size is qualified.
