Abstract
The invention relates to a contact head height measurement device which comprises a bottom plate (1), a vertical rod (6) and a scale (5). The vertical rod (6) is vertically installed on one side of the upper end face of the bottom plate (1), a scale installation seat (4) is sleeved on the outer side of the vertical rod (6), a screwing rod (7) is transversely installed on one side of the scale installation seat (4), the scale (5) is vertically installed at one end of the scale installation seat (4), an ejector pin (3) is installed at the lower end of the scale (5), and a contact locating block (2) is arranged below the ejector pin (3) and at the upper end of the bottom plate (1). The contact head height measurement device is simple in structure, reliable in operation, and fast and accurate in measurement, and greatly improves efficiency of contact ex-factory detection.
Description
Technical field
The present invention relates to the checkout equipment field of relay contact, particularly relate to a kind of contact height of head measurement mechanism.
Background technology
The contact is ingredient important in the relay, its performance is subjected to very large impact of following factor, material such as the contact, size, institute's making alive and current value (voltage and current waveform when particularly making contact excitation and de-energisation), the type of load, frequency of operation, atmospheric environment, contact configurations and beating.
At present, relay contact generally all adopts copper and the silver alloy composition that combines, the structure of contact is divided into head and foot, ag alloy layer is arranged in head more, therefore the height of head has a great impact the performance of contact, after produce the contact, all will measure the height of the head of contact, but the volume of contact is generally less, measurement is got up very inconvenient, and measurement is difficult to reach very accurate.
Summary of the invention
Technical matters to be solved by this invention provides a kind of contact height of head measurement mechanism, and is simple in structure, reliable, measures fast, accurately, greatly improved the efficient of contact factory testing.
The technical solution adopted for the present invention to solve the technical problems is: provide to comprise base plate, montant and scale, one side of the upper surface of described base plate vertically is equipped with a montant, the outside cover of described montant has the scale mount pad, described scale mount pad is fixed on the montant by swing arm, the elongation end of described scale mount pad vertically is equipped with scale, the lower end of described scale is equipped with a thimble, and the below of described thimble, the upper ends of base plate have a contact locating piece.
Be evenly arranged some row pilot holes on the upper surface of described contact locating piece, each is listed as the layout that tapers off to the size of described pilot hole to both sides by middle column.
The upper surface flush of the lower end of described thimble and contact locating piece.
The size of described pilot hole matches with the foot size of corresponding contact.
Beneficial effect
The present invention relates to a kind of contact height of head measurement mechanism, simple in structure, easy to operate, can measure rapidly and accurately the height of contact head, greatly improved the efficient of contact finished product detection, and the contact locating piece can change according to dissimilar contact, interchangeability is good.

Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As Figure 1-3, embodiments of the present invention relate to a kind of contact height of head measurement mechanism, comprise base plate 1, montant 6 and scale 5, one side of the upper surface of described base plate 1 vertically is equipped with a montant 6, the outside cover of described montant 6 has scale mount pad 4, described scale mount pad 4 is fixed on the montant 6 by swing arm 7, the elongation end of described scale mount pad 4 vertically is equipped with scale 5, the lower end of described scale 5 is equipped with a thimble 3, and the upper ends of the below of described thimble 3, base plate 1 has a contact locating piece 2.
Be evenly arranged some row pilot holes 21 on the upper surface of described contact locating piece 2, each is listed as the layout that tapers off to the size of described pilot hole 21 to both sides by middle column.
The upper surface flush of the lower end of described thimble 3 and contact locating piece 2.
The size of described pilot hole 21 matches with the foot size of corresponding contact.
Adopt the two composite contact foot of fine copper and silver-colored joint compound to be placed in the pilot hole corresponding on the contact locating piece 2 21 down with one, the foot of contact is inserted in the pilot hole 21, and head exposes on the surface of contact locating piece 2.The upper surface flush of the lower end of thimble 3 and contact locating piece 2, take the upper surface of contact locating piece 2 as reference field scale 5 is returned to zero, then current collector locating piece 2 makes thimble 3 tops be the height of contact head by the height of jack-up to the distance of centre position, head upper end thimble 3 risings of contact, and height value just is presented on the scale 5 accurately.
Claims (4)
1. contact height of head measurement mechanism, comprise base plate (1), montant (6) and scale (5), one side of the upper surface of described base plate (1) vertically is equipped with a montant (6), the outside cover of described montant (6) has scale mount pad (4), described scale mount pad (4) is fixed on the montant (6) by swing arm (7), the elongation end of described scale mount pad (4) vertically is equipped with scale (5), the lower end of described scale (5) is equipped with a thimble (3), it is characterized in that the below of described thimble (3), the upper ends of base plate (1) has a contact locating piece (2).
