DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5 , provides a workpiece size detection device, which aims to solve the defects of traditional detection, which generally requires manual inspection of workpieces one by one, with high labor intensity and low efficiency. In addition, it is affected by the unstable factors of manual operation and the detection accuracy of the workpiece cannot be accurately grasped. The specific embodiments are as follows:

[0026] Example 1

[0027] The support platform 10 is provided with a plurality of sets of embedding grooves 11 for placing workpieces. A limited material assembly 50 is disposed in each set of embedding grooves 11 , and a base plate 12 is provided at the end of each set of embedding grooves 11 .

[0028] By providing multiple sets of embedding grooves 11, multiple processed workpieces can be placed in one embedding groove 11 respectively, so as to realize batch measurement of workpieces, and the base plate 12 is the first base point for the size detection of the workpieces.

[0029] The pushing assembly 20 includes an electric cylinder body 21 mounted on the support platform 10 and a push plate 22 slidingly connected to the support platform 10. A plurality of flexible protrusions 23 are arranged at intervals on the push plate 22. The plurality of flexible protrusions 23 extend downward into a group of embedded grooves 11 respectively. The movable end of the electric cylinder body 21 is connected to the push plate 22, which is used to drive the plurality of flexible protrusions 23 to push the workpiece against the substrate 12 respectively.

[0030] The flexible protrusion 23 is preferably made of rubber material. After the workpiece is placed in the groove 11, the electric cylinder body 21 drives the push plate 22 to move toward the substrate 12, so that the flexible protrusion 23 moves along the groove 11 and pushes the workpiece against the substrate 12. Since the workpiece has different sizes after processing, the flexible protrusion 23 can deform to adapt to the workpiece. After the workpiece is against the substrate 12 in the groove 11 to determine the first base point position for detection, the electric cylinder body 21 drives it to push away from the substrate 12, so that the flexible protrusion 23 detaches from the workpiece.

[0031] The frame 30 is set on the support platform 10. The frame 30 is provided with a guide rod 31. The guide rod 31 is movably connected to a moving block 32. Two groups of spotlight bodies 34 are set on the moving block 32. The two groups of spotlight bodies 34 can emit two rays with a distance of allowable size tolerance downward.

[0032] The straight-line distance between the rays emitted by the two groups of spotlight bodies 34 and the substrate 12 is the minimum limit size and the maximum limit size. For example, the workpiece design has a given size of 30 cm, an upper deviation of 0.1 cm, and a lower deviation of 0.1 cm. Then the maximum limit size is 30.1 cm, the minimum limit size is 29.9 cm, and the allowable size tolerance value is 0.2 cm. It should be noted that the width of the rays emitted by the spotlight body 34 can be ignored for size detection.

[0033] The power assembly 40 is used to adjust the lateral distance between the moving block 32 and the substrate 12. The moving block 32 has a second base point. The lateral distance between the first base point and the second base point is the size given by the workpiece design. The moving block 32 can be adjusted according to the size given by the workpiece design.

[0034] The workpiece is placed in the embedding groove 11, and the electric cylinder body 21 drives multiple flexible protrusions 23 to push the workpiece and the substrate 12 to respectively determine the first base point position for detection and then reset. The power component 40 is controlled to adjust the lateral distance between the moving block 32 and the substrate 12 according to the given size of the part design. The two groups of spotlight bodies 34 emit two rays with a distance of allowable size tolerance downward. By observing the existence of rays exceeding the maximum limit size and rays not exceeding the minimum limit size, the workpiece is deemed unqualified, thereby realizing batch detection of workpiece size, with high detection accuracy, reduced labor intensity, and improved detection efficiency.

[0035] Example 2

[0036] The material limiting component 50 keeps the workpiece flush in the embedding groove 11 to prevent tilting. The material limiting component 50 includes multiple telescopic rods 51 arranged on the inner wall of the embedding groove 11. The multiple telescopic rods 51 are connected to the partition 52, and each telescopic rod 51 is wrapped with a spring 53. Under the elastic force of the spring 53, the partition 52 is driven to push the workpiece to remain flush.

[0037] A plurality of supporting balls 111 are provided at the bottom of each set of embedding grooves 11 to reduce the movement resistance of the workpiece in the embedding grooves 11 .

[0038] Example 3

[0039] The two groups of spotlight bodies 34 are slidably connected to the moving block 32 through the slider 33 respectively, and each group of spotlight bodies 34 is screwed with an adjustment column 331 that can be against the moving block 32. The moving block 32 is provided with positive scale lines and negative scale lines.

[0040] The second base point is the zero point between the positive scale line and the negative scale line. By adjusting the positions of the two groups of spotlight bodies 34 on the moving block 32, the upper deviation and the lower deviation can be adjusted and adapted.

[0041] The power assembly 40 includes a power source 41 mounted on the frame 30 . The output end of the power source 41 is connected to a screw rod 42 . The screw rod 42 is screwed to a seat 43 . The seat 43 is connected to the moving block 32 . The power source 41 signal is connected to the controller.

[0042] The power source 41 is preferably a servo motor, which drives the screw rod 42 to rotate to drive the base body 43 to move laterally, thereby driving the movable plate to move and adjust the lateral distance from the base plate 12.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
