Abstract
The utility model relates to a testing device for a piano descent control device, which comprises a motion mechanism and a controller (7). The motion mechanism comprises a stent (1), a fixed plate (2), a moving plate (3) and a balance cylinder (5); and one end of the balance cylinder (5) is articulated with the moving plate (3) through a push rod (4) and the other end thereof is articulated with the stent (1). The utility model relates to a testing device for detecting the descent control device by simulating the slow descent process of the piano keyboard cover; the operation is simple, as long as the descent control device is mounted, a switch is turned on and testing conditions are set, the testing result can be obtained quickly and no people are needed to watch aside; and the testing result is high reliable, unqualified descent control devices are prevented from being applied to the piano and the quality of the piano is ensured.
Description
Technical field
The utility model belongs to piano parts detection range, particularly relates to a kind of piano key lid descending lifeline pick-up unit.
Background technology
Piano in use, and the security consideration of opening for key lid all can be loaded onto a piano key lid descending lifeline; The switch of key lid is very flat numerous simultaneously, so the quality of piano key lid descending lifeline is with regard to very important; Piano key lid descending lifeline being installed in real key the quality of tested steel keyboard cover descending lifeline the time in the prior art covers and tests, such test period is long, relatively waste, and cost is also high, mostly existing method of testing is to operate manually simultaneously, very inconvenient.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of piano key lid descending lifeline pick-up unit, to solve the high defective of testing cost in the prior art.
A kind of Sustained piano closer pick-up unit, comprise motion and controller (7), described motion comprises support (1), fixed head (2), portable plate (3) and compensating cylinder (5), one end of described compensating cylinder (5) is hinged by push rod (4) and portable plate (3), and the other end and support (1) are hinged.
Described Sustained piano closer pick-up unit, described controller (7) comprises time controller, counter, pressure controller.
Beneficial effect
The utility model is the test unit that detects descending lifeline by the slow process of falling of simulation piano key lid, simple to operate, as long as descending lifeline is loaded onto, starting switch sets test condition, just can obtain test findings very soon, and do not choose and aside see always, test findings with a high credibility stopped underproof descending lifeline and used on the piano, and the quality of piano is guaranteed.
Description of drawings
View when Fig. 1 is positioned at horizontal level for portable plate;
View when Fig. 2 is positioned at the upright position for portable plate;
Fig. 3 is the synoptic diagram of controller.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
A kind of Sustained piano closer pick-up unit comprises motion and controller 7, and described motion comprises support 1, fixed head 2, portable plate 3 and compensating cylinder 5, and an end of described compensating cylinder 5 is hinged by push rod 4 and portable plate 3, and the other end and support 1 are hinged; Described controller 7 comprises time controller, counter, pressure controller, and counter is used for controlling frequency (whenever finishing the time of an action), the weight when pressure controller setting analog key lid falls of setting test number (TN), time controller setting test.
During use Sustained piano closer 6 is contained in simulation piano key lid on fixed head 2 and the portable plate 3, the power switch 71 on the start-up control device 7, power light 72 is bright, and machine begins to start.Portable plate 3 is positioned at Fig. 2 state, begins to charge into gases at high pressure in second cylinder 52, promotes push rod 4 and moves to the K direction, push rod 4 pushes away portable plate 3 by free bearing and rotates, Sustained piano closer 6 rotates thereupon, and when portable plate 3 is up to the standard state as shown in Figure 1 the time, the process of push rod 4 is intact must; Then second cylinder 52 stops air inlet, the 51 beginning air inlets of first cylinder, and gases at high pressure promote push rod 4 and move to "-K " direction, and extremely to getting back to stationary state, push rod resets, compensating cylinder 5 venting, portable plate 3 is got back to Fig. 2 state.A workflow is finished, and counts display screen 73 on the controller this moment and shows numerical value 1, and time display screen 74 is for to finish the time that backhaul is required.Action above repeating is to the test number (TN) that reaches setting.When reaching test number (TN), properties of product do not change, and then qualified pilot lamp 75 is bright, illustrates that this product is qualified; If do not reach test number (TN), variation has just taken place in the performance of product, and then defective pilot lamp 76 is bright, illustrates that this product is defective.
Claims (2)
1. Sustained piano closer pick-up unit, it is characterized in that: comprise motion and controller (7), described motion comprises support (1), fixed head (2), portable plate (3) and compensating cylinder (5), one end of described compensating cylinder (5) is hinged by push rod (4) and portable plate (3), and the other end and support (1) are hinged.
2. Sustained piano closer pick-up unit as claimed in claim 1, it is characterized in that: described controller (7) comprises time controller, counter, pressure controller.
