Description

Technical Field

[0001] This utility model relates to the field of valve core testing technology, and in particular to a testing device for valve core processing. Background Technology

[0002] A search revealed a patent (application number: 201821577368.4) that discloses "a hardness testing device for valve core processing." This device applies pressure to the valve core by having a pressure testing rod slide down from inside a pressure rod adjustment box, ensuring that the valve core is not damaged during measurement. This effectively solves the problems of mediocre measurement results and surface damage when measuring valve core hardness. However, this device has the following problems during use:

[0003] First, the device mainly provides lateral force to the valve core through two valve core fixing patches. However, most existing valve cores are irregularly shaped parts, which rely solely on opposing clamping and are prone to shaking during the testing process, resulting in poor stability.

[0004] In addition, because the device uses a single hardness test, the test results only include hardness data, making the test method too simplistic and the data insufficient. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a testing device for valve core processing, which overcomes the shortcomings of the prior art and effectively solves the problems of poor stability and insufficient testing data.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A valve core processing testing device includes a testing table, an electric guide rail is installed on the top outer wall of the testing table, and an arm is fixedly connected to the slider of the electric guide rail. A slide block is fixedly connected to the outer wall of one end of the arm, and a stand is provided on one side of the slide block.

[0008] The top outer wall of the testing platform is welded with symmetrically distributed side plates, and a horizontal cylinder is fixedly connected to the inner wall of one of the side plates. The piston rod of the horizontal cylinder is fixedly connected to a connector, and a sealing cover is welded to the inner wall of one end of the connector. An air pipe is fixedly connected to the outer wall of one side of the sealing cover.

[0009] The top outer wall of the testing platform is rotatably connected to a main shaft, and the outer wall of the main shaft is fixedly connected to a top pressure claw. An oblique cylinder is hinged between the top pressure claw and the testing platform.

[0010] Preferably, a valve core body is placed between the slide and the stand.

[0011] Preferably, the inner wall of the slide is provided with a slot, and the valve core body is disposed on the inner wall of the slot.

[0012] Preferably, a top frame is welded between the two side plates, and an electrical control screen is installed on the outer wall of the top of the top frame.

[0013] Preferably, a hydraulic push rod is installed on the top outer wall of the top frame inside the electronic control panel, and the piston rod of the hydraulic push rod is fixedly connected to a pressure detection head.

[0014] Preferably, a support frame is fixedly connected to the top outer wall of the testing platform, and a slide block is slidably connected to the outer wall of the support frame.

[0015] Preferably, a solenoid valve is installed on the outer wall of the trachea, and the solenoid valve and the electronic control panel are connected by a signal line.

[0016] Preferably, a pressure gauge is installed on the outer wall of the trachea on one side of the solenoid valve.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. The valve core processing inspection device designed in this paper has a slide and a stand that can be well adapted to the valve core.

[0019] 2. The valve core processing testing device designed in this paper can detect the air tightness of the valve core during the air filling process by simultaneously pushing the pressure testing head downward with the hydraulic push rod to squeeze the valve core to test its hardness and pushing the sealing cover close to the valve core with the horizontal cylinder. This increases the air tightness data, reflects the versatility of the device design, and enriches the test data.

[0020] 3. The valve core processing testing device designed in this paper has high stability, is well adapted to the irregular structure of the valve core, which helps to improve the accuracy of the device's testing results. In addition, it adopts a variety of testing methods, which can provide a comprehensive understanding of the valve core's quality. Attached Figure Description

[0039] Working principle: First, the valve core is placed between the slide 4 and the stand 5, with one end of the valve core placed in the slot 19. The slide 4 is pushed by the electric guide rail 2 to press the valve core between the slide 4 and the stand 5. Then, the top pressure claw 12 is pushed by the inclined cylinder 13 to fix the top of the valve core, thus completing the positioning operation of the valve core. Afterwards, the pressure detection head 17 is pushed down by the hydraulic push rod 16 to press the valve core and detect the hardness of the valve core.
