[0022] The technical solution of this utility model will be clearly and completely described below through specific embodiments.

[0023] This utility model discloses a fixture for an image measuring instrument, comprising a housing 1, a lateral adjustment assembly, a base plate 8, an electric push rod 12, and a clamping block 13; the specific structure is as follows: Figures 1-3 As shown, the housing 1 is a horizontally arranged hollow cuboid structure, and its upper surface is also provided with rectangular horizontally symmetrical base plates 8. Horizontal adjustment components are also provided between the lower surfaces of each pair of adjacent base plates 8 and the housing 1, and each base plate 8 moves horizontally on the housing 1 through the horizontal adjustment components. Electric push rods 12 are also provided horizontally on the upper surface of each base plate 8 near the center of the housing 1. The tail of each electric push rod 12 is fixedly installed on the corresponding position on the upper surface of the corresponding base plate 8 by a fixing rod, and the fixing rod ensures the fixed stability of the corresponding electric push rod 12. The pushing end of each electric push rod 12 is set towards the center of the housing 1 and is screwed to the corresponding clamping block 13, thereby driving the corresponding clamping block 13 to perform horizontal and vertical position adjustments, thereby clamping and fixing the product to be tested.

[0024] like Figure 3 As shown, each clamping block 13 is a horizontally arranged hollow cuboid structure, with its upper surface, one side near the lateral center of the housing 1, and one side near the longitudinal center of the housing 1 all being open. The side away from the longitudinal center of the housing 1 is screwed to the pushing end of the corresponding electric push rod 12. Driven by the corresponding electric push rod 12, each clamping block 13 moves horizontally longitudinally to adjust its position in the Y-axis direction. Each clamping block 13 is made of a transparent plate, ensuring that it does not affect the product to be tested placed on the inner bottom surface of the four clamping blocks 13. During the clamping process, the side away from the lateral center of the housing 1 is used for lateral positioning of the product to be tested.

[0025] Each lateral adjustment component of this utility model includes a housing 1, a support column 2, a slide rail 3, a rack 4, a rib plate, a motor 6, a slider 5, and a gear 7; for example... Figure 1, Figure 2 As shown, inside the shell 1, there are also vertically arranged support columns 2 arranged in a rectangular symmetrical pattern, and each support column 2 is fixedly connected to the inner bottom surface and the corresponding inner surface of the shell 1. In the middle position between each pair of adjacent support columns 2, there is also a horizontally arranged rack 4, and the tooth surface of each rack 4 is arranged facing the front. The two ends of each rack 4 are fixedly connected to the inner side of the corresponding support column 2. In addition, several ribs for supporting the rack 4 are arranged vertically at intervals along its length between its lower surface and the inner bottom surface of the shell 1. In addition, there are horizontally arranged slide rails 3 on the front and rear sides directly above each rack 4 and inside the shell 1. The two ends of each pair of adjacent slide rails 3 are screwed and fixed to the left and right inner sides of the shell 1, and the two ends of their lower surfaces are fixedly connected to the upper surface of the corresponding support column 2.

[0026] like Figure 1 , Figure 2 As shown, at the four right angles on the lower surface of each base plate 8, sliders 5 matching the slide rails 3 are vertically and symmetrically fixed. The position of each slider 5 corresponds to the position of each slide rail 3, and they extend vertically downward into the interior of the housing 1 and are connected to the corresponding slide rails 3, so that the base plate 8 is horizontally and laterally connected to the corresponding slide rails 3 through the sliders 5. On the upper surface of each base plate 8, away from the middle of the housing 1 and between the two slide rails 3, a motor 6 is vertically fixed. The output end of each motor 6 extends vertically downward into the interior of the housing 1 and is connected to the corresponding rack 4 through gears 7. Driven by the motor 6, the four base plates 8 reciprocate horizontally on the housing 1 through the meshing of gears 7 and rack 4, and drive the clamping block 13 to reciprocate horizontally. Each motor 6 does not interfere with the movement of the corresponding electric push rod 12, and each pair of adjacent slide rails 3 does not interfere with the movement of the corresponding gear 7.

[0027] like Figure 1 , Figure 2 As shown, four horizontally arranged first strip grooves 10 are vertically embedded in the upper surface of the housing 1 from front to back. Each first strip groove 10 is matched with each slider 5, and its setting position corresponds to the horizontal sliding trajectory of the corresponding slider 5. Thus, by setting the first strip grooves 10, it is ensured that the housing 1 does not interfere with the horizontal movement of the four base plates 8.

[0028] like Figure 1 , Figure 2As shown, a second strip groove 11 is also horizontally and vertically embedded between each two adjacent first strip grooves 10 on the upper surface of the housing 1. Each second strip groove 11 is matched with the output end of the corresponding motor 6, and its setting position is corresponding to the horizontal sliding trajectory of each motor 6. Thus, by setting the second strip groove 11, it is ensured that the housing 1 does not interfere with the horizontal movement of the four base plates 8.

[0029] like Figure 1 , Figure 2 As shown, mounting plates 9 are symmetrically arranged horizontally on the left and right outer sides of the housing 1 near its bottom end, and each mounting plate 9 is located near the front and rear edges of the housing 1. The housing 1 is screwed and fixed to the detection platform of the image measuring instrument through the mounting plates 9.

[0030] The working principle of this utility model is as follows: First, the housing 1 is screwed and fixed to the detection platform of the image measuring instrument by the mounting plate 9. Then, the X-axis and Y-axis positions of the four clamping blocks 13 are adjusted by the cooperation of the lateral adjustment component and the electric push rod 12 to adapt to the product to be tested. Then, the product to be tested is placed horizontally on the inner bottom surface of the four clamping blocks 13. Then, by further driving the lateral adjustment component and the electric push rod 12, the four clamping blocks 13 clamp and fix the product to be tested, and then the image measuring instrument can be used to measure the product to be tested.

[0031] The beneficial effects of this utility model are:

[0032] (1) By using the lateral adjustment component and the electric push rod 12 together, this utility model can realize the horizontal lateral and vertical movement of the clamping block 13, which makes it easy to clamp and fix products of different specifications to be tested, and has a wide range of applications.

[0033] (2) By setting the clamping block 13, this utility model facilitates the positioning and clamping of the product to be tested. At the same time, because it is made of transparent plate, it will not affect the measurement of the image measuring instrument, thus improving the measurement accuracy.
