Description

Technical Field

[0001] This utility model relates to the field of valve body technology, and in particular to a clamp for cleaning ABS valve bodies. Background Technology

[0002] A valve is defined as a device in a fluid system used to control the direction, pressure, and flow rate of a fluid. Valves allow the flow or stop of media (liquid, gas, powder) within piping and equipment, and can control their flow rate. The cleanliness requirements for ABS valve bodies in automotive parts are extremely high (excessive cleanliness can affect product safety performance), and ordinary ultrasonic cleaning cannot meet these requirements.

[0003] The patent search revealed a hydraulic clamp for machining automotive valve bodies (202123231099.0). This device uses two clamping blocks to fix the center positions of both sides of the automotive valve body, making the valve body more secure during machining and preventing constant adjustments due to valve body misalignment. The hydraulic clamp's lead screw and motor are also adjustable, facilitating left and right adjustments during different machining operations. This makes adjusting the machining position more convenient and saves time. However, fixing the valve body at two points results in instability during rinsing due to the different angles of the rinsing pressure acting on the valve body. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems and shortcomings by proposing a clamp for cleaning ABS valve bodies. This clamp, composed of a support assembly, a pressing assembly, and another support assembly, provides multi-faceted fixation of the valve body, improving the stability of the rinsing process. Simultaneously, the multi-point fixation reduces the clamp's obstructed area, facilitating cleaning. This also solves the problem of instability caused by two-point support.

After adjustment, the nut is screwed into the threaded protrusion 6 to fix the support strip 7. Then, the knob is rotated to adjust the position of the contact head 10.

[0025] The support bar 7 has equally spaced adjustment holes at the threaded protrusion 6, and the outer wall of the threaded protrusion 6 is threaded with a nut. The bottom outer wall of the support screw 9 is welded with a knob. Rotating the knob adjusts the position of the contact head 10 of the support screw 9, and adjusts the position of the valve body in the mounting frame 1. The valve body is placed in the mounting frame 1, and the bottom outer wall of the valve body is placed on the contact head 10, which facilitates the placement of the valve body and reduces the obstruction area of ​​the valve body.

[0026] Example 2:

[0027] Reference Figure 1-3 The fixing component 5 includes an extension rod 11 installed on the top outer wall of the mounting frame 1, sliding grooves 12 opened on the outer walls of both ends of the extension rod 11, a piston groove 13 opened on the inner wall of the other end of the sliding groove 12, a piston 15 slidably connected to the inner wall of the piston groove 13, a sliding rod 16 installed at the center of the other end of the piston 15, and a contact piece 17 installed at the other end of the sliding rod 16. Gas is sent to the outer piston groove 13 through the gas passage 19 and the delivery pipe 18. The gas in the piston groove 13 supports the movement of the piston 15. The piston 15 pushes the sliding rod 16 and the contact piece 17 to contact the outer wall of the valve body, thereby supporting and fixing the side of the valve body.

[0028] The outer wall of the sliding rod 16 is slidably connected to the inner wall of the sliding groove 12, and the other end of the piston 15 is welded with a return spring 14, the other end of which is installed on the inner wall of one end of the piston groove 13.

[0029] Both ends of the extension rod 11 are provided with air passages 19, and one end of the extension rod 11 located in the air passage 19 is connected to a delivery pipe 18, and the other end of the delivery pipe 18 is connected to the piston groove 13.

The piston 15 drives the sliding rod 16 and the contact piece 17 to contact the outer wall of the valve body, which facilitates pneumatic support, facilitates fixing the valve body and improves stability.

[0030] The pressing assembly 4 includes a pressing rod 21 installed on the outer wall of the mounting frame 1, a piston groove 22 opened on the top outer wall of the pressing rod 21, a piston 24 slidably connected to the inner wall of the piston groove 22, a descending rod 25 installed on the top outer wall of the piston 24, and a return spring 23 installed on the bottom outer wall of the piston 24.

[0031] The other end of the return spring 23 is installed on the inner wall of the bottom of the piston groove 22, and the outer wall of the other end of the descending rod 25 is bonded with a protective pad 26. The bottom outer wall of the pressing rod 21 is provided with an air passage 27, and one end of the pressing rod 21 located in the air passage 27 is provided with an inflation head 28. The other end of the air passage 27 is connected to the piston groove 22. The gas in the piston groove 22 is drawn out through the inflation head 28 and the air passage 27, so that the descending rod 25 and the piston 24 descend. The protective pad 26 at the other end of the descending rod 25 contacts the outer wall of the valve body, and the valve body is restricted in conjunction with the support assembly 3 for easy fixation.

[0032] Working principle: During use, the support bar 7 is adjusted by adjusting the position of the support screw 9 through the adjustment hole in the threaded protrusion 6 according to the size of the valve body. After adjustment, the nut is screwed into the threaded protrusion 6 to fix the support bar 7. Then, the support screw 9 is rotated to adjust the position of the contact head 10, adjusting the position of the valve body in the mounting frame 1. The valve body is placed in the mounting frame 1, with the bottom outer wall of the valve body resting on the contact head 10, which facilitates the placement of the valve body and reduces the obstruction area of ​​the valve body. Then, gas is injected into the air passage 19 in the extension rod 11 through the air inlet 20. The gas is sent to the outer piston groove 13 through the air passage 19 and the delivery pipe 18. The gas in piston groove 13 supports the movement of piston 15. Piston 15 pushes sliding rod 16 and contact piece 17 to contact the outer wall of valve body, supporting and fixing the side of valve body. Air is drawn into piston groove 22 through air inlet 28. Air passage 27 draws gas from piston groove 22, causing descending rod 25 and piston 24 to descend, so that the protective pad 26 at one end of descending rod 25 contacts the top outer wall of valve body. The combination of support component 3, pressing component 4 and fixing component 5 fixes the valve body in multiple ways, improving the stability of the flushing process. At the same time, the multi-point fixing reduces the obstruction area of ​​the clamp, making cleaning easier.
