Description

Technical Field

[0001] The utility model relates to the technical field of nut size detection, in particular to a size detection device used for producing nuts. Background Art

[0002] In the highly precise nut manufacturing industry, accurate measurement of nut dimensions is essential to ensuring that the final product meets quality standards. However, the traditional nut dimension detection equipment currently in widespread use faces the dual challenges of insufficient measurement accuracy and flexibility. Specifically, these devices are often limited by a fixed measuring head design and can only measure nut dimensions within a specific range. Once faced with diverse production requirements, such as nuts of varying diameters and thread depths, frequent measuring head replacement or complex mechanical adjustments are required. This process is not only time-consuming and labor-intensive, but also prone to human error, reducing measurement accuracy.

[0003] Furthermore, conventional equipment has significant shortcomings when distinguishing the outer diameter of a nut from the outer diameter of the thread groove. Due to design limitations, these devices often struggle to accurately distinguish and measure these two critical dimensions, which, to a certain extent, limits their application in precision manufacturing. To address this, we offer a dimensional inspection device for nut production. Utility Model Content

[0004] In order to solve the above problems, the present invention proposes a size detection device for producing nuts, so as to more accurately solve the problems raised in the above background technology.

[0005] The utility model is realized by the following technical solutions: a size detection device for producing nuts, comprising a fixed block and a guide slide fixedly installed between the two fixed blocks, a middle load block fixedly installed between the two guide slides and in the middle, a mounting rod slidably sleeved on the periphery of the guide slide, a prismatic groove is formed at the end of the mounting rod, a prismatic insert is inserted at the inner wall of the prismatic groove, a detection rod is fixedly installed at the end of the prismatic insert, and the detection rod has two designs, cylindrical and triangular. The cylindrical rod is used to measure the outer diameter of the nut, and the triangular rod is used to measure the outer diameter of the nut thread groove. A disassembly structure is connected between the mounting rod and the prismatic insert;

[0006] The disassembly and assembly structure includes a limiting groove opened on the side of the mounting rod, and the limiting groove is connected to the prismatic groove. A rectangular groove is opened horizontally on the prismatic plug-in block, and an arc-shaped limiting block is slidably connected to the inner wall of the rectangular groove, and the arc-shaped limiting block is reset and inserted into the inner wall of the limiting groove to prevent the prismatic plug-in block from being pulled out. A reset component is connected between the rectangular groove and the arc-shaped limiting block.

[0007] As a further technical solution of the present invention, the reset component includes a placement groove opened on the inner side wall of the rectangular through groove, a transverse fixing rod is fixedly connected between the two end walls of the placement groove, the outer sleeve of the transverse fixing rod is provided with a spring, the outer sliding sleeve of the transverse fixing rod is connected with a sliding sleeve block, and the sliding sleeve block is slidably connected at the inner wall of the placement groove.

[0008] As a further technical solution of the present invention, a measuring ruler is fixedly installed between the fixed block and the middle load block, and the measuring ruler is designed to be directly above the mounting rod. A pointer is fixedly connected to the upper end surface of the mounting rod for indicating a specific scale value.

Users can quickly select the appropriate inspection rod based on the specific specifications of the nut to be tested without having to replace the entire inspection device, thereby improving work efficiency.

[0014] 2. A dimension inspection device for producing nuts effectively enhances the stability and durability of the device by introducing reset components such as Spring 2 and Spring 1. Spring 2 provides elastic support for the mounting rod, reducing its shaking during the sliding process and improving measurement stability and accuracy.

[0019] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1-Figure 3 As shown, an embodiment of the present invention proposes a size detection device for producing nuts. First, two fixed blocks 1 are prepared, and two guide slides 2 are fixedly installed between the two fixed blocks 1 to ensure that the two guide slides 2 are parallel and stable. Then, a hole is punched on the middle load block 3 so that it can be fixedly installed in the middle position of the two guide slides 2. The mounting rod 4 is designed to be able to slide freely along the guide slide 2, and the prismatic groove 5 opened at its end is used to receive the prismatic insert 6. The design of the prismatic insert 6 allows it to be firmly inserted into the prismatic groove 5. At the same time, the detection rod 7 connected to its end can be selected as a cylindrical or triangular design according to needs, which are used to measure the outer diameter of the nut and the outer diameter of the thread groove respectively. The disassembly structure realizes the rapid installation and disassembly of the prismatic insert 6 through the cooperation of the limiting groove 8 and the rectangular groove 9, and the arc-shaped limiting block 14 under the action of the reset component.

[0021] Furthermore, the reset component includes a receiving slot 10 formed in the inner wall of the rectangular through-slot 9, and a transverse fixing rod 11 fixedly connected at both ends of the receiving slot 10. A spring 12 is sleeved around the periphery of the transverse fixing rod 11, and a sliding sleeve 13 is slidably engaged therewith. The sliding sleeve 13 is connected to an arcuate stopper 14. When the arcuate stopper 14 is inserted into the stopper slot 8, the elastic force of the spring 12 maintains its stability, preventing the prismatic insert 6 from being accidentally removed.

[0022] The reset component ensures the stability and reliability of the assembly and disassembly mechanism, allowing the prismatic insert 6 to remain securely attached to the mounting rod 4 when not pushed by external forces. One end of spring 12 is fixedly connected to the end wall of the mounting groove 10, while the other end is fixedly connected to one end surface of the sliding sleeve 13. This design allows spring 12 to directly apply elastic force to the sliding sleeve 13, thereby pushing the arc-shaped stopper 14 to achieve its locking and unlocking functions.

[0023] Furthermore, to improve measurement accuracy, a measuring ruler 15 is fixedly mounted between the fixed block 1 and the intermediate load block 3, and is designed to be directly above the mounting rod 4. A pointer 16 is fixedly connected to the upper end surface of the mounting rod 4. When the mounting rod 4 slides along the guide rod 2, the pointer 16 can indicate the specific scale value on the measuring ruler 15.

[0024] Furthermore, to enhance the stability of the mounting rod 4 during sliding, an annular plate 17 is fixedly connected to the periphery of one guide rod 2, and a second spring 18 is provided. One end of the second spring 18 is connected to the end of the fixed block 1, and the other end is connected to the annular plate 17, forming an elastic support for the mounting rod 4.

[0025] The design of the second spring 18 effectively reduces the shaking of the mounting rod 4 during the sliding process, thereby improving the stability and accuracy of the measurement. The connection method of the second spring 18 is further refined, specifically, one end of the second spring 18 is directly fixedly connected to the end surface of the fixing block 1, and the other end is fixedly connected to the surface of the annular piece 17. This connection method ensures that the second spring 18 can fully exert its elastic support function.
