Abstract
The utility model discloses a kind of testing pressure head detent mechanism, it comprises base (1), horizontal location post (2), measuring head locating piece (3), dog screw (4) and dog screw supporting seat (5), measuring head locating piece (3) is placed on base (1), and the lower surface that contacts with base (1) of measuring head locating piece (3) offers square groove (6), horizontal location post (2) is arranged on the upper surface of base (1), and with square groove (6) sliding connection, measuring head locating piece (3) left and right sides side is provided with location screw support seat (5), dog screw supporting seat (5) internal thread is connected with a dog screw (4), dog screw supporting seat (5) is arranged on the upper surface of base (1) by screw.The beneficial effects of the utility model are: it has the advantage that adjustment position is convenient, measuring head can be avoided to tilt and save production cost.
Description
Technical field
The utility model relates to detent mechanism, particularly a kind of testing pressure head detent mechanism.
Background technology
Wafer having multiple contact, when testing, needing contact to contact with contact, but in existing proving installation, after repeatedly using, easily there are wearing and tearing in measuring head, causes test crooked to easily occurring in moving process, thus can not be vertically downward during die pressing product under making measuring head, cause the contact to be measured on contact and wafer not in place, affect the accuracy of product test, serious also can causing scratches contact, cause product rejection, improve production cost.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of and adjusts the testing pressure head detent mechanism that position is convenient, measuring head can be avoided to tilt and save production cost.
The purpose of this utility model is achieved through the following technical solutions: a kind of testing pressure head detent mechanism, it comprises base, horizontal location post, measuring head locating piece, dog screw and dog screw supporting seat, described measuring head locating piece is placed on base, and the lower surface of measuring head locating piece and base contacts offers square groove, described horizontal location post is arranged on the upper surface of base, and with square groove sliding connection, described measuring head locating piece left and right sides side is provided with a location screw support seat, dog screw supporting seat internal thread is connected with a dog screw, dog screw supporting seat is arranged on the upper surface of base by screw.
The square groove of described measuring head locating piece lower surface is twice.
Described horizontal location post is four, and the horizontal location post be slidably matched in each square groove is two.
The utility model has the following advantages: detent mechanism of the present utility model, the position of measuring head locating piece is regulated by dog screw, and be provided with horizontal location post, measuring head locating piece horizontal parallel is moved, thus test is forbidden and tests not in place caused product rejection when avoiding measuring head inclination, thus it has the advantage that adjustment position is convenient, can avoid measuring head inclination and save production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that schematic diagram figure is looked on a left side of the present utility model;
Fig. 3 is the cross-sectional schematic of A-A in Fig. 1;
In figure, 1-base, 2-horizontal location post, 3-measuring head locating piece, 4-dog screw, 5-dog screw supporting seat, 6-square groove.
Embodiment
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As depicted in figs. 1 and 2, a kind of testing pressure head detent mechanism, it comprises base 1, horizontal location post 2, measuring head locating piece 3, dog screw 4 and dog screw supporting seat 5, described measuring head locating piece 3 is placed on base 1, and the lower surface that contacts with base 1 of measuring head locating piece 3 offers square groove 6, described horizontal location post 2 is arranged on the upper surface of base 1, and with square groove 6 sliding connection, described measuring head locating piece 3 left and right sides side is provided with a location screw support seat 5, dog screw supporting seat 5 internal thread is connected with a dog screw 4, dog screw supporting seat 5 is arranged on the upper surface of base 1 by screw.
As shown in Figure 3, in the present embodiment, the square groove 6 of described measuring head locating piece 3 lower surface is twice, and horizontal location post 2 is four, and the horizontal location post 2 be slidably matched in each square groove 6 is two.
The course of work of the present utility model is as follows: by regulating dog screw 4, measuring head locating piece is slided, because horizontal location post 2 and square groove sliding connection, move so the movement of measuring head locating piece 3 is parallel, horizontal, vertical depression when ensure that measuring head presses down test products, when avoiding measuring head locating piece 3 to tilt, test is inaccurate or test not in place and waste product that is that cause.
