Description

Technical Field

[0001] This utility model relates to the field of measuring tool technology, and more specifically, to a depth gauge structure. Background Technology

[0002] A depth gauge is a high-precision measuring tool used to quickly and accurately measure dimensions such as hole depth, step height, and groove depth. The measuring rod of the depth gauge must be strictly perpendicular to the bottom surface of the base; tilting will cause measurement errors. In existing technologies, the parts where the depth gauge base and body, body and frame are fixedly connected are processed through multiple separate processes. This makes it difficult to guarantee the perpendicularity of the measuring rod to the bottom surface of the base, resulting in low processing efficiency and high production costs. Summary of the Invention

[0003] This invention aims to at least partially solve one of the aforementioned technical problems in the prior art. Therefore, one objective of this invention is to provide a depth gauge structure that is simple in structure, requires fewer processing steps, has good perpendicularity between the measuring rod and the base surface, high processing efficiency, and low production cost.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] The depth gauge structure is characterized by comprising a base and a gauge body. One end of the base is provided with a base surface, and the end away from the base surface is provided with the gauge body, which is fixedly connected to the base and perpendicular to the base surface. The end of the gauge body away from the base is provided with a gauge frame, and the gauge frame is provided with a sliding groove along its length direction. The two ends of the gauge body extend out of the two ends of the gauge frame through the sliding groove, and the gauge frame can move along the length direction of the gauge body.

[0006] The beneficial effects of this utility model are: it optimizes the basic structure of the depth gauge, improves product stability, and when the gauge body and the gauge frame slide relative to each other after assembly, the sliding of the gauge frame is smooth and not easily jammed, which is conducive to mass production, improves assembly efficiency and product qualification rate, and reduces production costs.

[0007] Based on the above technical solution, the present invention can be further improved as follows:

[0008] The base has a waist-shaped groove perpendicular to the base surface at one end away from the base surface, and the ruler body has a waist-shaped boss at one end connected to the base. The ruler body and the base are fastened together by the waist-shaped boss and the waist-shaped groove.

[0009] The beneficial effects of adopting the above-mentioned further solution are: when the arc-shaped side of the waist-shaped groove mates with the side of the waist-shaped boss, it can effectively restrict the radial movement of the ruler body and ensure the alignment of the ruler body on the base. At the same time, the contact between the end face of the waist-shaped boss and the waist-shaped groove can restrict the axial degree of freedom of the ruler body and simplify assembly positioning.

[0010] Furthermore, the waist-shaped boss is a tapered waist-shaped boss, with a tapered side that gradually decreases in size from the inner end face to the outer end face.

[0011] The beneficial effects of adopting the above-mentioned further scheme are: the waist-shaped boss gradually decreases in size from the inner end face to the outer end face; the fit between the tapered waist-shaped boss and the waist-shaped groove gradually transitions from clearance fit to interference fit; the preload and the mechanical locking of the waist-shaped boss work together to prevent loosening; the tapered guide makes assembly easier; the combination of the tapered waist-shaped boss and the waist-shaped groove provides a larger friction contact surface; and the structure is more robust and reliable.

[0012] Furthermore, a C-shaped groove and a measuring rod are provided at the end of the ruler frame near the base. The measuring rod is parallel to the ruler body and is fastened to the ruler frame through the C-shaped groove.

[0013] The advantages of adopting the above-mentioned further solution are as follows: The C-shaped circular groove has a "C"-shaped cross-section with an opening on one side. This allows for the simultaneous machining of the sliding groove and the C-shaped circular groove using equipment with better performance and faster processing speed, effectively ensuring the parallelism of the sliding groove and the C-shaped circular groove, and further ensuring the perpendicularity of the measuring rod to the base surface. Furthermore, the C-shaped groove enables rapid assembly of the measuring rod, and welding technology is used to reinforce the ruler frame and measuring rod at the "C"-shaped opening, better ensuring the concentricity and stability of the measuring rod and the C-shaped circular groove, preventing rotation and loosening of the measuring rod.

[0014] Furthermore, a clearance space is provided at one end of the C-shaped circular groove near the center of the ruler frame 3.

[0015] The beneficial effects of adopting the above-mentioned further solution are: the clearance position is located at the end of the C-shaped groove, providing space for the tool to retract. The tool can retract from here without having to return from the C-shaped groove along the machining path, ensuring machining accuracy and surface quality, and facilitating accurate alignment of the measuring rod during assembly.

[0016] Furthermore, the base is provided with a measuring rod hole communicating with the base surface. The measuring rod hole is concentric with the C-shaped groove. The measuring rod can movably pass through the measuring rod hole, extend out of the base surface, and be perpendicular to the base surface.

[0017] The beneficial effect of adopting the above-mentioned further solution is that it can manufacture measuring rods of various sizes according to measurement needs, and quickly and accurately measure various dimensions such as hole depth, step height, and groove depth.

[0030] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0031] like Figures 1 to 7 As shown, a depth gauge structure includes a base 1 and a gauge body 2. One end of the base 1 is provided with a base surface 101, and the end away from the base surface 101 is provided with the gauge body 2, which is fixedly connected to the base 1 and perpendicular to the base surface 101. The end of the gauge body 2 away from the base 1 is provided with a gauge frame 3. The gauge frame 3 is provided with a sliding groove 301 along its length direction. The two ends of the gauge body 2 extend out of the two ends of the gauge frame 3 through the sliding groove 301. The gauge frame 3 can move on the gauge body 2 along the length direction of the gauge body 2.

[0032] In the above embodiment, the base 1 is provided with a waist-shaped groove 102 perpendicular to the base surface 101 at one end away from the base surface 101; the ruler body 2 is provided with a waist-shaped boss 201 at one end connected to the base 1, and the ruler body 2 and the base 1 are fastened together by the waist-shaped boss 201 and the waist-shaped groove 102.

[0033] In the above embodiments, the waist-shaped boss 201 is a tapered waist-shaped boss with a tapered side that gradually decreases in size from the inner end face to the outer end face.

[0034] In the above embodiment, the ruler frame 3 is provided with a C-shaped circular groove 302 and a measuring rod 4 near the end of the base 1. The measuring rod 4 is parallel to the ruler body 2 and is fastened to the ruler frame 3 through the C-shaped circular groove 302.

[0035] In the above embodiment, a clearance position 303 is provided at one end of the C-shaped circular groove near the center of the ruler frame 3.

[0036] In the above embodiment, the base 1 is provided with a measuring rod hole 103 communicating with the base surface 101. The measuring rod hole 103 is concentric with the C-shaped circular groove 302. The measuring rod 4 extends movably through the measuring rod hole 103 out of the base surface 101 and is perpendicular to the base surface 101.

[0037] In this embodiment, the basic structure of the depth gauge is optimized to improve product stability. When the gauge body 2 and the gauge frame 3 slide relative to each other after assembly, the sliding of the gauge frame 3 is smooth and not easily jammed, which is conducive to mass production, improves assembly efficiency and product qualification rate, and reduces production costs.

[0038] When the curved side of the waist-shaped groove 102 mates with the side of the waist-shaped boss 201, it can effectively restrict the radial movement of the ruler body 2 and ensure the alignment of the ruler body 2 on the base 1. At the same time, the contact between the end face of the waist-shaped boss 201 and the waist-shaped groove 102 can restrict the axial degree of freedom of the ruler body 2 and simplify assembly positioning.

[0039] The waist-shaped boss 201 gradually decreases in size from the inner end face to the outer end face. The fit between the tapered waist-shaped boss 201 and the waist-shaped groove 102 gradually transitions from a clearance fit to an interference fit. The preload and the mechanical locking of the waist-shaped boss 201 work together to prevent loosening. The tapered guide makes assembly easier. The combination of the tapered waist-shaped boss 201 and the waist-shaped groove 102 provides a larger friction contact surface, making the structure more robust and reliable.

[0040] The C-shaped circular groove 302 has a "C"-shaped cross-section and is open on one side. This allows for the simultaneous machining of the sliding groove 301 and the C-shaped circular groove 302 using higher-performance, faster equipment, effectively ensuring the parallelism of the sliding groove 301 and the C-shaped circular groove 302, and further ensuring that the measuring rod 4 is perpendicular to the base surface 101. On the other hand, the C-shaped groove enables the rapid assembly of the measuring rod 4, and welding technology is used to reinforce the ruler frame 3 and the measuring rod 4 at the "C"-shaped opening, better ensuring the concentricity and stability of the measuring rod 4 and the C-shaped circular groove 302, and preventing the measuring rod 4 from rotating or loosening.

[0041] The clearance position 303 is located at the end of the C-shaped groove 302, providing space for the tool to retract. The tool can retract from here without having to return from the C-shaped groove 302 along the machining path, ensuring machining accuracy and surface quality, and facilitating the accurate fit of the measuring rod 4 during assembly.

[0042] Various sizes of measuring rods 4 can be manufactured according to measurement needs to quickly and accurately measure various dimensions such as hole depth, step height, and groove depth.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
