The testing table of folding key

Technical field

The present invention relates to a kind of testing table of folding key, especially a kind of testing table that is used to detect the endurance quality of folding key.

Background technology

At present, folding key on the market various in style, obviously the security of folding key is a matter of utmost importance, and the endurance quality of folding key itself determines its serviceable life, also directly influence its security, so must mainly be that the endurance quality of the hyoid tooth rotation of folding key detects test to each parts in the folding key.At present folding key is carried out the endurance quality test and do not appear in the newspapers as yet, the special purpose test equipment of domestic this respect still belongs to blank.

Summary of the invention

The object of the present invention is to provide that a kind of simple in structure, dirigibility is strong, easy operating, be convenient to safeguard, the testing table of folding key that reliability is high.

The objective of the invention is to be achieved through the following technical solutions:

A kind of testing table of folding key, it is characterized in that: this testing table comprises stand, is fixed on control module and topworks on the stand, stand is provided with worktable, on worktable, be provided with the anchor clamps that are used for fixing folding key, topworks is made up of pressing mechanism and rotating mechanism, and the pneumatic element that the drive signal that control module provides is formed through solenoid valve drives pressing mechanism and rotating mechanism and is in and presses down the location status of opening folding key or rotating closed folding key cycle alternation.

The invention has the advantages that: in the testing table of folding key, be provided with pressing mechanism and be used to press down the button of opening on the folding key, be provided with the hyoid tooth that rotating mechanism is used to stir folding key, cooperate PLC programming Control module, simple in structure, this testing table can imitate the basic status that people normally use folding key, and cyclic test constantly, dirigibility is strong, easy operating.

Embodiment

A kind of testing table of folding key, comprise stand 10, be fixed on control module 20 and topworks on the stand 10, as shown in Figure 1, stand 10 is provided with worktable 11, on worktable 11, be provided with the anchor clamps 12 that are used for fixing folding key 50, topworks is made up of pressing mechanism 30 and rotating mechanism 40, as shown in Figure 2, the pneumatic element formed through solenoid valve of the drive signal that provides of control module 20 drives pressing mechanism 30 and rotating mechanism 40 and is in and presses down the location status of opening folding key 50 or rotating closed folding key 50 cycle alternations.

Described rotating mechanism 40 comprises a rotary cylinder 41 that is fixed in the stand 10, as shown in Figure 1, a pivot arm 42 of postponing and have to be used to stir the hyoid tooth 52 of folding key 50 in its lower end, pivot arm 42 adopts eccentric the setting, be that pivot arm 42 is in apart from the centre of gyration of rotary cylinder 41 position at regular intervals, and the running orbit of the hyoid tooth 52 of its running orbit and folding key 50 is consistent, can imitate the basic status that people normally use folding key 50.

Described pressing mechanism 30 comprises a linear cylinder 31 that is fixed in the stand 10, as shown in Figure 1, linear cylinder 31 is arranged on the side of rotary cylinder 41, and its axis direction is consistent with the axis direction of rotary cylinder 41, a press rods 32 that postpones and have to be used to press down the button 51 on the folding key 50 in the lower end of linear cylinder 31, press rods 32 is the knuckle shape of 90 degree, the one end is connected in the lower end of linear cylinder 31, the other end is positioned at the top of the button 51 on the folding key 50, the stroke that press rods 32 moves up and down is less than the lower end of rotary cylinder 41 and the spacing between the folding key 50, to avoid press rods 32 and pivot arm 42 in motion process, to interfere, simultaneously, made full use of the inner space of testing table.

Described control module 20 is positioned at the side of the running orbit of press rods 32 and pivot arm 42, as shown in Figure 1, hinders press rods 32 and pivot arm 42 to move to avoid control module 20.

Among the present invention, stand 10 is made by aluminium section, worktable 11 is made by iron material, and control module 20 is selected PLC programmable control module 20 for use, before the test, as shown in Figure 1, folding key 50 is fixed on the worktable 11 by anchor clamps 12, and tightens with bolt, and the hyoid tooth 52 of folding key 50 contacts with the arm body of pivot arm 42, at this moment, press rods 32 is in a high position.

During test, the input end of PLC programmable control module 20 is connected the AC power of 220V, make its inside transform out the 24V direct supply, the input point receiving position signal of PLC programmable control module 20, by its internal processes computing, its output point is exported corresponding signal, and the break-make of this signal controlling solenoid valve is to control the motion of linear cylinder 31, rotary cylinder 41.After 20 energisings of PLC programmable control module, solenoid valve is charged, linear cylinder 31 air inlets, linear cylinder 31 drives press rods 32 and moves down until the button of pushing on the folding key 50 51, as shown in Figure 2, subsequently, rotary cylinder 41 air inlets, rotary cylinder 41 driven rotary arms 42 rotate and stir the hyoid tooth 52 of folding key 50, and hyoid tooth 52 is entered in the cavity of folding key 50, as shown in Figure 3, folding key 50 closures, subsequently, linear cylinder 31 drive press rods 32 move upward and get back to initial position, as shown in Figure 4, press rods 32 is separated with button 51, and subsequently, original state is got back in 42 rotations of rotary cylinder 41 driven rotary arms, as shown in Figure 5, pivot arm 42 separates with folding key 50.Hereto, a test period finishes.Then, the air inlet once more of linear cylinder 31, and drive press rods 32 and press down button 51 on the folding key 50, as shown in Figure 6, folding key 50 is opened, and its hyoid tooth 52 contacts with the arm body of pivot arm 42, repeats above-mentioned loop cycle subsequently and tests.As seen, the present invention can either imitate the basic status that people normally use folding key 50, can constantly open again or closed folding key 50, test again and again, and simple in structure, easy operating of the present invention, dirigibility is strong.

As mentioned above, core of the present invention is to reach the purpose that the permanance of folding key 50 is tested by control module 20 driving pressing mechanisms 30 and rotating mechanism 40.
