Abstract
The utility model relates to a wire clamp of a comparing measurement instrument of a three-dimensional shape track. The wire clamp comprises a chassis (1), a support (1a) and a swing arm (6), wherein a locking screw rod (9) penetrates the support (1a) and the swing arm (6) and is linked and matched with a locking nut (14); a pull rod (7) and a spring matched with the pull rod (7) are arranged in swing arm seats (6a) at two ends of the swing arm; adjustment hand wheels (2) are connected to an outward end of the pull rod (7); and a workpiece top ring is connected with one inward end of the pull rod (7). The wire clamp of the comparing measurement instrument of the three-dimensional shape track has the advantages that due to the connection design of a combined structure, the multidirectional revolving observing to the measured wire is realized, the working requirement of the comparing measurement instrument is satisfied; and the wire clamp of the comparing measurement instrument of the three-dimensional shape track is simple in structure, stable in performance, simple and convenient in operation, and available for quality detection of microelectronic and micromechanic precise members.
Description
Technical field
The utility model relates to police criminal detection appreciation field, particularly relates to a kind of wire clamp that on three-dimensional appearance vestige matching measurement appearance, uses.
Background technology
China is to the comparison and the detection of the aspects such as bullet, shell case and instrument line trace of bullet at present; Still be in the situation of analyzing with sample storage in kind; Detection to mark information still rests on the technological layer by single instrument Direct observation two dimensional image comparison, can't solve an accurate location survey difficult problem that in three dimensions object appearance technology and vestige comparison technology, exists.When using three-dimensional appearance vestige matching measurement appearance, because the needs of the multiple instrument lines of observation lack a kind of anchor clamps of being convenient to wire rod observation.
The utility model content
The purpose of the utility model is exactly in order to solve the shortcoming that three-dimensional appearance vestige matching measurement appearance lacks wire rod observation anchor clamps, a kind of wire clamp that is used for three-dimensional appearance vestige matching measurement appearance to be provided.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of wire clamp of three-dimensional appearance vestige matching measurement appearance is characterized in that comprising:
A, chassis, chassis are provided with a pair of bearing;
B, swing arm, swing arm take the shape of the letter U and are arranged between a pair of bearing, and tie down screw is connected cooperation after wearing and passing a side bearing, swing arm bottom and opposite side base successively with set nut, are provided with holding screw bottom the swing arm and wear with tie down screw and cooperate;
C, swing arm two ends respectively are provided with a swing arm seat; Be provided with the pull bar of a perforation in the cavity of each swing arm seat; Sheathed spring on the pull bar; Spring one end cooperates with the cavity end face of swing arm seat, the other end cooperates with locating ring on the pull bar, and the outside end of pull bar is connected with adjustment handwheel, an inside end joining work pieces apical ring, and the end face of workpiece apical ring is provided with anti-slip tank.
During use, this wire clamp is placed on the universal stage of matching measurement appearance, draws back pull bar, will measure wire rod and be placed between the workpiece apical ring, rely on spring force will measure wire rod and step up; Swing arm taken up decide screw rod and rotate to correct position, tighten set nut; Use control hand wheel to be rotated adjustment to measuring wire rod.
Employing the utility model has the advantages that through adopting the connection design of unitized constructions such as swing arm and pull bar; Realized measuring the multi-directional rotation observation of wire rod; The measuring instrument requirements of one's work have been satisfied; It is rational in infrastructure, stable performance, easy and simple to handle, can be used for the quality testing of microelectronics micromechanics precision part, thereby improves the quality inspection technology level and work efficiency.

Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
Like Fig. 1-shown in Figure 4, the wire clamp of a kind of three-dimensional appearance vestige matching measurement appearance that the utility model provides comprises following ingredient:
A, chassis 1, chassis 1 are provided with a pair of bearing 1a that keeps at a certain distance away;
B, swing arm 6, swing arm 6 takes the shape of the letter U, and its bottom also is arranged between a pair of bearing 1a; Referring to Fig. 4,, by a tie down screw wear 9 pass a side bearing, swing arm bottom and opposite side base successively after; Be connected cooperation with set nut 14, swing arm bottom is provided with holding screw 10 and wears 9 with tie down screw and cooperate;
C, referring to Fig. 3; Swing arm 6 two ends respectively are provided with a swing arm seat 6a, are provided with the pull bar 7 of a perforation in the cavity of each swing arm seat, sheathed spring 5 on the pull bar 7; Spring 5 one ends cooperate with the cavity end face plug 4 of swing arm seat, the other end cooperates with locating ring 7a on the pull bar 7; Pull bar 7 outside ends are connected with adjustment handwheel 2 and fixing by screw 3 connections, pull bar 7 inside end joining work pieces apical rings 8, and the end face of workpiece apical ring is provided with anti-slip tank 8a.
Above-described only is the preferred implementation of the utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be regarded as belonging to the protection domain of the utility model.
