Description

Technical Field

[0001] This utility model relates to the field of valve handwheel processing technology, specifically to an adjustable fixture for valve handwheel processing. Background Technology

[0002] During the processing of valve handwheels, some handwheels require a protective paint coating. Currently, after the protective coating is applied, the handwheels are often placed on a support for natural drying. However, most of the current supports for placing handwheels are fixed, which is not conducive to the placement of handwheels of different shapes. Furthermore, some handwheels still have surface defects after the protective coating is applied, requiring surface grinding or polishing to improve the appearance of the valve. Existing supports often have poor stability, necessitating the removal of the handwheel from the support for further processing. This not only increases the workload but also affects the processing efficiency. Therefore, an adjustable fixture for valve handwheel processing is proposed. Utility Model Content

[0003] The purpose of this invention is to address the issue that some valve handwheels still have surface defects after the protective coating is applied, requiring further grinding or polishing to improve their appearance. Existing supports often have poor stability, necessitating the removal of the valve handwheel from the support for further processing, which is labor-intensive and reduces processing efficiency. This invention provides an adjustable fixture for processing valve handwheels.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] An adjustable fixture for machining valve handwheels includes a base plate. A snap-fit ​​groove is formed on the side wall of the base plate, and a support column is inserted and installed in the snap-fit ​​groove. A height adjustment mechanism is provided on the side wall of the support column, and multiple connecting crossbars are provided on the height adjustment mechanism. Multiple connecting square holes are formed on the side wall of the multiple connecting crossbars, and a handwheel positioning mechanism is provided in the connecting square holes. A handwheel locking mechanism is provided on one side of the handwheel positioning mechanism on the connecting crossbar.

[0006] Preferably, an annular groove is formed on the side wall of the base plate, and an annular air filter element is provided in the annular groove. An assembly hole is formed on the side wall of the base plate, and the assembly hole is connected to the annular groove. A vent pipe is inserted into the assembly hole.

[0007] Preferably, an annular slot is provided on one side of the annular groove on the side wall of the base plate, and a protective ring plate is inserted and installed in the annular slot.

[0008] Preferably, the height adjustment mechanism includes a support ring, which is slidably sleeved on the side wall of the support column, and the side wall of the support ring is provided with an adjustment screw hole. The side wall of the support column is provided with a plurality of insertion screw holes, and the insertion screw holes and the adjustment screw holes are matched and arranged in a matching manner. Adjustment bolts are provided in the insertion screw holes and the adjustment screw holes.

[0009] Preferably, the handwheel positioning mechanism includes a connecting square rod, which is slidably inserted into a connecting square hole, and both ends of the connecting square rod are provided with locking screws, and locking screw rings are screwed into the locking screws.

[0010] Preferably, the handwheel locking mechanism includes a locking component, and a plurality of locking screw holes are provided on the connecting crossbar around the connecting square hole. The locking component includes a tapered column, one end of which is fixedly installed with a locking bolt, and the locking bolt is matched with the locking screw hole. The other end of the tapered column is fixedly installed with a rotating column.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, the valve handwheel after being coated with a protective layer of paint can be placed on the connecting crossbar, so that the locking screw on the upper side passes through the central ring of the valve handwheel, and then it is fixed by the locking screw ring. The distance between the connecting crossbars can be easily adjusted by the multiple insertion screw holes and support rings on the support column, and fixed by adjusting bolts. The distance between two adjacent valve handwheels can be adjusted by the connecting square hole and connecting square rod, so as to facilitate the clamping and fixing of valve handwheels of different shapes, and thus facilitate their natural air drying. At the same time, the vent pipe can be connected to an external air suction device, and under the protection of the protective ring plate, the air is drawn away through the annular air filter, thereby reducing the amount of odor and harmful gas leakage generated by the paint during the drying process.

[0013] 2. In this utility model, when it is necessary to reprocess the surface of individual valve handwheels, the locking bolts on the locking components are screwed into the locking screw holes of the connecting crossbar. The tapered column then presses against the connecting rib on the valve handwheel, and the two locking components can be used to complete the left and right locking of the valve handwheel. This allows the valve handwheel to be stably clamped on the connecting crossbar, making it easier for workers to perform surface grinding or polishing and other repair processing. This saves workers the workload of transportation and repositioning of the valve handwheel, and also improves the processing efficiency of the valve handwheel. Attached Figure Description

[0024] like Figure 1-5 As shown, an adjustable fixture for processing valve handwheels includes a base plate 1. An annular groove 6 is formed on the side wall of the base plate 1, and an annular air filter element 7 is disposed in the annular groove 6. An assembly hole 4 is formed on the side wall of the base plate 1, and the assembly hole 4 is connected to the annular groove 6. A vent pipe 5 is inserted into the assembly hole 4. An annular slot 2 is formed on one side of the annular groove 6 on the side wall of the base plate 1, and a protective ring plate 3 is inserted into the annular slot 2. An air suction device can be connected to the vent pipe 5, and under the protection of the protective ring plate 3, the air is drawn away through the annular air filter element 7, thereby reducing the amount of odor and harmful gas leakage generated by the paint during the drying process.

[0025] A snap-fit ​​groove 14 is provided on the side wall of the base plate 1, and a support column 8 is inserted and installed in the snap-fit ​​groove 14. A height adjustment mechanism is provided on the side wall of the support column 8. The height adjustment mechanism includes a support ring 10, which is slidably sleeved on the side wall of the support column 8. An adjustment screw hole 11 is provided on the side wall of the support ring 10. Multiple insertion screw holes 9 are provided on the side wall of the support column 8, and the insertion screw holes 9 are matched with the adjustment screw holes 11. An adjustment bolt 12 is provided in the insertion screw holes 9 and the adjustment screw holes 11. By providing multiple insertion screw holes 9 and support ring 10 on the support column 8, the distance between the upper and lower connecting crossbars 13 can be easily adjusted, and then fixed by the adjustment bolt 12, so as to adapt to the placement and clamping of valve handwheels of different heights.

[0026] The support ring 10 is provided with multiple connecting crossbars 13. Multiple connecting square holes 15 are opened on the side walls of the multiple connecting crossbars 13. A handwheel positioning mechanism is provided in the connecting square holes 15. The handwheel positioning mechanism includes a connecting square rod 16, which is slidably inserted into the connecting square hole 15. Both ends of the connecting square rod 16 are provided with locking screws 17. Locking screw rings 18 are screwed into the locking screws 17. The distance between two adjacent valve handwheels can be adjusted through the connecting square holes 15 and the slidably set connecting square rods 16, so as to facilitate the clamping and fixing of valve handwheels of different widths and shapes.

[0027] A handwheel locking mechanism is provided on one side of the handwheel positioning mechanism on the connecting crossbar 13. The handwheel locking mechanism includes locking components 20. Multiple locking screw holes 19 are opened on the periphery of the connecting square hole 15 on the connecting crossbar 13. The locking component 20 includes a tapered column 2002. A locking bolt 2003 is fixedly installed at one end of the tapered column 2002, and the locking bolt 2003 is matched with the locking screw hole 19. A rotating column 2001 is fixedly installed at the other end of the tapered column 2002. The left and right locking of the valve handwheel can be completed by means of two locking components 20. By cooperating with the upper and lower locking of the locking screw ring 18, it is convenient for workers to perform surface grinding or polishing and other repair processing. This can save workers the workload of transportation and repositioning of the valve handwheel, and can also improve the processing efficiency of the valve handwheel.

[0028] In summary: After applying a protective coating, the valve handwheel is installed on the connecting crossbar 13, with the upper locking screw 17 passing through the central ring of the valve handwheel. The locking ring 18 is then used for vertical fixation. Based on the size of the valve handwheel, a support ring 10 is installed on the support column 8. Multiple insertion screw holes 9, combined with the adjusting screw holes 11 on the support ring 10, facilitate adjustment of the distance between the upper and lower connecting crossbars 13. This is then secured with adjusting bolts 12. Furthermore, by inserting the connecting square rod 16 into different connecting square holes 15, the distance between adjacent valve handwheels can be adjusted, allowing for the clamping and fixing of valve handwheels of different sizes. By connecting the vent pipe 5 to an external air intake device, and then allowing the air to be filtered through the annular air filter element 7 under the protection of the protective ring plate 3, the amount of odor and harmful gas leakage generated by the paint during the drying process is reduced, thus facilitating its natural air drying. When it is necessary to reprocess the surface of individual valve handwheels, the locking bolts 2003 on the locking parts 20 are screwed into the locking screw holes 19 of the connecting crossbar 13, thereby using the tapered column 2002 to press against the connecting rib on the valve handwheel. Then, the left and right locking of the valve handwheel can be completed with the help of the two locking parts 20. This can stably clamp the valve handwheel on the connecting crossbar 13, thus facilitating the workers to perform surface grinding or polishing and other repair processing.
