Description

Technical Field

[0001] This utility model relates to the field of high-pressure cleaning technology for multi-way valves, and in particular to a fixed fixture for high-pressure cleaning of multi-way valves. Background Technology

[0002] After the honing process, the multi-way valve needs to be cleaned of iron filings and honing fluid from the valve body, and rust needs to be removed. It needs to be cleaned in a high-pressure cleaning equipment. Therefore, it is necessary to develop a fixed fixture for high-pressure cleaning of multi-way valves to facilitate thorough cleaning of multi-way valves in high-pressure cleaning equipment. Utility Model Content

[0003] To address the issue of securing multi-way valves during high-pressure cleaning, this invention provides a high-pressure cleaning fixture for multi-way valves. The fixture uses support pins to hold the workpiece in place and four positioning seats to engage the front and rear sides of the workpiece. By incorporating sensing screws and pin holes, when the fixture is conveyed into the high-pressure cleaner via rollers, the cleaner automatically inserts its positioning pins into the pin holes upon sensing the screws, locking the fixture in place. This prevents movement during high-pressure cleaning, making cleaning more convenient, faster, and more thorough.

[0004] To achieve the above objectives, this utility model provides a multi-way valve high-pressure cleaning fixing fixture, comprising an upper base plate, a lower base plate, a first positioning seat, a second positioning seat, and a third positioning seat. The upper and lower base plates are arranged in parallel, and the four corners of the upper base plate are fixedly connected to the lower base plate via connecting rods. The lower base plate has a first square through-groove in the middle and a second square through-groove in the middle, the second square through-groove being smaller than the first square through-groove. A square boss extending into the groove is provided on the inner wall of the right front side of the second square through-groove, and a first arc-shaped boss extending into the groove is provided on the inner wall of the left front corner. Second arc-shaped bosses extending into the groove are provided on both the left and right sides of the rear inner wall. Supporting pins are provided on the square bosses, the first arc-shaped bosses, and the second arc-shaped bosses for support. The workpiece has two first positioning seats, symmetrically positioned on the left front and right front sides of the second square through slot on the upper base plate, for workpiece positioning. The second and third positioning seats are respectively positioned on the left rear and right rear sides of the second square through slot on the upper base plate, for engaging with the first positioning seats to engage the workpiece and prevent it from tipping over during high-pressure cleaning. A sensing screw is located in the middle of the right side of the upper base plate, and a pin hole is located in the middle of the right side of the lower base plate. The high-pressure cleaner is equipped with a sensor and a positioning pin. The sensor sends a sensing signal to the controller of the high-pressure cleaner when it approaches the sensing screw. After receiving the signal, the controller issues a control command to automatically insert the positioning pin on the high-pressure cleaner into the pin hole, locking the multi-way valve high-pressure cleaning fixture.

[0005] Furthermore, the first positioning seat includes a first mounting plate and a positioning post. The positioning post is a square post and is fixedly connected to the right rear corner of the upper surface of the first mounting plate. The right side and rear side of the positioning post are flush with the right side and rear side of the first mounting plate, respectively. The upper end of the right side of the positioning post is provided with a first inclined surface that tilts to the left, and the upper end of the rear side is provided with a second inclined surface that tilts to the front. The first mounting plate has a first through hole at the right front corner and the left rear corner. The upper base plate has a first threaded hole at the corresponding position of the first through hole. A first bolt is provided in the first through hole. The lower end of the first bolt is threadedly connected to the first threaded hole, so that the first positioning seat is detachably and fixedly connected to the upper base plate.

[0006] Furthermore, the right rear corner edge of the positioning post is provided with a first chamfer, and the left front corner of the first mounting plate is provided with a second chamfer.

[0007] Furthermore, the second positioning seat includes a second mounting plate and a first upright plate. The first upright plate is fixedly connected to the middle of the upper surface of the second mounting plate. The front side of the first upright plate is flush with the front side of the second mounting plate. The upper end of the front side of the first upright plate is provided with a third inclined surface that slopes backward. The second mounting plate has first oblong holes on both the left and right sides. The upper base plate has second threaded holes at positions corresponding to the first oblong holes. A second bolt is inserted into the first oblong hole, and the lower end of the second bolt is threadedly connected to the second threaded hole, so that the second positioning seat is detachably and fixedly connected to the upper base plate.

[0008] Furthermore, the third positioning seat includes a third mounting plate and a second upright plate. The second upright plate is fixedly connected to the middle of the upper surface of the third mounting plate. The front side of the second upright plate is flush with the front side of the third mounting plate. The upper end of the front side of the second upright plate is provided with a fourth inclined surface that slopes backward. The third mounting plate has second oblong holes on both the left and right sides. The upper base plate has third threaded holes at positions corresponding to the second oblong holes. A third bolt is inserted into the second oblong hole, and the lower end of the third bolt is threadedly connected to the third threaded hole, so that the third positioning seat is detachably and fixedly connected to the upper base plate.

[0009] Furthermore, the support pin includes an upper support column and a lower fixing column coaxially connected. The outer diameter of the upper support column is larger than the outer diameter of the lower fixing column. The lower fixing columns at the lower ends of the four support pins are respectively inserted into a square boss, a first arc-shaped boss, and two second arc-shaped bosses. The outer cylindrical surface of the upper support column is provided with a clearance cutting plane.

[0010] Furthermore, the connecting rod is a double-ended screw rod with a middle outer diameter larger than the outer diameter of the threads at both ends. The lower end is threaded to the lower base plate, and the upper end passes through the upper base plate. The upper and lower base plates are fixedly connected by a flat washer, a spring washer, and a locking nut. The middle outer circular surface of the connecting rod has two symmetrically arranged tangent planes for engaging with a wrench, facilitating the rotation of the connecting rod to the threaded connection with the lower base plate, and simultaneously adjusting the height of the upper base plate to make the upper base plate parallel to the lower base plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model supports the workpiece by setting support nails and sets four positioning seats to lock the front and rear sides of the workpiece. By setting sensing screws and pin holes, when the multi-way valve high-pressure cleaning fixture is conveyed into the high-pressure cleaner by the roller belt, the high-pressure cleaner senses the sensing screw through the sensor and automatically inserts the positioning pin of the high-pressure cleaner into the pin hole to lock the multi-way valve high-pressure cleaning fixture. This can prevent the fixture from moving during high-pressure cleaning, making cleaning more convenient, faster and more thorough. Attached Figure Description
