[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1: Reference Figure 1-Figure 3 , a mechanical parts dimension detection device, which is used in the field of mechanical parts detection technology, includes a base plate 1. A fixed baffle 3 is fixed to the top of the base plate 1, and a first groove 4 is opened in the base plate 1. Two second limiting rods 16 are fixed in the first groove 4, and the surface of the two second limiting rods 16 is slid with the same movable baffle 5. The fixed baffle 3 and the movable baffle 5 are used to position and measure the dimensions of mechanical parts. A group of positioning components are provided in the movable baffle 5, and the positioning components are used to position the movable baffle 5. It also includes an extrusion component used in conjunction with the positioning component, and the extrusion component is provided in the movable baffle 5 to release the positioning of the movable baffle 5 by the positioning component. A height measuring component is provided in the fixed baffle 3 to detect the height of mechanical parts.

[0026] The positioning assembly includes a U-shaped frame 2 fixed to the top of the base plate 1. A third groove 8 is defined on both sides of the U-shaped frame 2. A fifth groove 18 is defined in the movable baffle 5. Two extrusion blocks 17 slide within the fifth groove 18. A positioning spring 19 is fixed between the two extrusion blocks 17. The two extrusion blocks 17 are in pressurized contact with the inner walls of the two third grooves 8, respectively. When the movable baffle 5 moves into the U-shaped frame 2, the two extrusion blocks 17 are squeezed inward by the inner walls of the third grooves 8, compressing the positioning springs 19. When the third groove 8 moves completely below the extrusion blocks 17, the extrusion blocks 17 pop out under the action of the positioning springs 19 and contact the inner walls of the third groove 8, thereby positioning the movable baffle 5.

[0027] In order to increase the friction between the third grooves 8 and the extrusion blocks 17 and prevent the movable baffle 5 from sliding after being positioned, anti-slip pads are fixed to the ends of the two third grooves 8 and the two extrusion blocks 17 that are away from each other.

[0028] The extrusion assembly includes a second groove 6 defined within the movable baffle 5, within which a pressing block 7 slides. Two extrusion rods 21 are fixed to the bottom end of the pressing block 7. An extrusion groove 20 is defined within each of the two extrusion blocks 17. The two extrusion rods 21 respectively move downwardly and penetrate the two extrusion grooves 20. The two extrusion rods 21 respectively come into contact with the inclined surfaces of the two extrusion blocks 17. A second scale 13 is provided at the side end of the U-shaped frame 2. When the movable baffle 5 needs to be moved, the pressing block 7 is pressed, which drives the two extrusion rods 21 downward. The two extrusion rods 21 respectively come into contact with and squeeze the inclined surfaces of the two extrusion blocks 17, causing the two extrusion blocks 17 to move inward and compress the positioning spring 19. At this point, the movable baffle 5 can be moved, and the movement distance of the movable baffle 5 can be observed using the second scale 13.

[0029] In order to enable the pressing block 7 to automatically reset when no force is applied, two reset springs 22 are fixed to the bottom end of the pressing block 7 , and both reset springs 22 are fixed in the second groove 6 .

[0030] Example 2: Reference Figure 1-Figure 3, based on the improvement of Example 1: the height measuring assembly includes a first scale 12 provided on the side end of the fixed baffle 3, a fourth groove 10 is provided in the fixed baffle 3, two first limit rods 14 are fixed in the fourth groove 10, the same top plate 9 slides on the surface of the two first limit rods 14, a lifting screw 15 rotates in the fourth groove 10, the top plate 9 is threadedly connected to the surface of the lifting screw 15, the side end of the lifting screw 15 moves outward to penetrate the fixed baffle 3 and is fixed to the rotating rod 11. When it is necessary to measure the height of the mechanical part, the mechanical part is placed on the base plate 1 with one side in contact with the fixed baffle 3, the rotating rod 11 is rotated, the rotating rod 11 drives the lifting screw 15 to rotate, and the lifting screw 15 drives the top plate 9 to move upward until the top plate 9 contacts the mechanical part. At this time, the height of the mechanical part can be read by the first scale 12.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
