[0002] Currently, there is no effective way to detect the condition of the extrusion surface after the hydraulic tappet ball / plunger inner hole is extruded. The only way to confirm whether there is leakage is through performance testing after assembly, which reduces the subsequent qualification rate. Rework reduces production efficiency and causes certain damage to other normal parts. Summary of the invention

[0003] The purpose of the utility model is to provide a technical solution for a hydraulic tappet ball plunger inner hole air tightness rapid detection device in response to the existing design and production methods. The solution can realize online rapid detection of air tightness of the hydraulic tappet ball / plunger inner hole after extrusion processing, so that the extrusion processing size can be effectively controlled and the production efficiency can be improved.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a device for quickly detecting the air tightness of the inner hole of a hydraulic tappet ball plug plunger, comprising a base plate (1), a fixing seat a (2), a fixing seat b (3), an air pressure regulating valve (4), a glass rotor flowmeter (5), a toggle clamp (6), a ball / plunger (7), a mounting seat (8), an O-ring a (9), a steel ball (10), a tower spring (11), an O-ring b (12), a base (13), and a pillar (14); the air pressure regulating valve, the glass rotor flowmeter, and the base are connected in sequence through an air pipe; the air pressure regulating valve is mounted on the base plate through a self-provided bracket; the glass rotor flowmeter is mounted on the base plate through the fixing seats a and the fixing seats b; the mounting seat is mounted on the base through bolts and then mounted on the base plate through pillars; the tower spring is connected to the steel ball and mounted on the base; and the toggle clamp is mounted on the base plate through a screw.

[0005] As a preferred embodiment of this solution: the mounting seat is connected to the base by bolts, an O-ring mounting groove is designed on the base, and an O-ring b is installed to prevent air leakage.

[0006] As a preferred embodiment of this solution: an O-ring installation groove is designed in the mounting hole of the mounting seat, and an O-ring a is installed. When the ball / plunger is installed, the O-ring effectively seals the outer cylindrical surface of the ball / plunger to prevent air leakage, so that the gas can only be discharged through the inner hole.

[0007] As a preferred embodiment of this solution: the tower-shaped spring connected steel ball is installed on the base to ensure that the steel ball is basically located at the center of the mounting hole of the mounting seat, so that it can better contact with the ball / plunger extrusion surface.

[0008] The beneficial effects of the utility model are as follows: the device has low cost and strong versatility, and can realize online rapid detection of air tightness of the hydraulic tappet ball / plunger inner hole after extrusion processing, so that the extrusion processing size can be effectively controlled, thereby ensuring product performance while improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a front view of the structure schematic diagram of the utility model.

[0010] In the figure: 1-base plate, 2-fixed seat a, 3-fixed seat b, 4-air pressure regulating valve, 5-glass rotor flowmeter, 6-elbow clamp, 7-ball / plunger, 8-mounting seat, 9-O-ring a, 10-steel ball, 11-tower spring, 12-O-ring b, 13-base, 14-pillar. DETAILED DESCRIPTION

[0011] In order to clearly illustrate the technical features of this solution, the solution is described below through a specific implementation method and in conjunction with the accompanying drawings.

[0012] like Figure 1 As shown, a device for quickly detecting the air tightness of the inner hole of a hydraulic tappet ball plunger comprises a base plate (1), a fixing seat a (2), a fixing seat b (3), an air pressure regulating valve (4), a glass rotor flowmeter (5), an elbow clamp (6), a ball / plunger (7), a mounting seat (8), an O-ring a (9), a steel ball (10), a tower spring (11), an O-ring b (12), a base (13), and a support (14). The air pressure regulating valve (4), the glass rotor flowmeter (5), and the base (13) are connected in sequence through an air pipe. The air pressure regulating valve (4) is mounted on the base plate (1) through a self-provided bracket. The glass rotor flowmeter (5) is mounted on the base plate (1) through a fixing seat a (2) and a fixing seat b (3). An O-ring a (9) is arranged in the mounting hole of the mounting seat (8). After the ball / plunger (7) is rotated into the mounting hole, the O-ring a (9) seals the outer cylindrical surface of the ball / plunger (7) to prevent air leakage. The mounting seat (8) is installed by bolts. The base (13) is mounted on a base with an O-ring b (12) to prevent air leakage, and then mounted on a bottom plate (1) via a support (14); a tower-shaped spring (11) is connected to a steel ball (10) and mounted on the base (13); when the ball / plunger (7) is mounted on a mounting seat (8), the steel ball (10) simulates the actual assembly situation and is pressed against the extrusion processing surface of the ball / plunger (7); the elbow clamp (6) is mounted on the bottom plate (1) via a screw rod, and the height is adjusted via the screw rod so that it just presses the ball / plunger (7).

[0013] When the device is working, the high-pressure gas is adjusted to a suitable pressure through the pressure regulating valve (4), and then flows into the inlet end of the glass rotor flowmeter (5), and then enters the base (13) from its outlet end, and then enters the mounting seat (8). At this time, the steel ball (10) is pressed against the extrusion processing surface of the ball / plunger (7) through the tower spring (11), playing a sealing role. The gas leakage here will be intuitively reflected on the glass rotor flowmeter (5), thereby achieving a rapid detection of the air tightness of the inner hole of the ball / plunger (7) after extrusion processing.

[0014] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
