Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and particularly relates to a needle gauge clamp for measuring. Background Art

[0002] When processing casing blade slots, it is often encountered that the blade slot area is too small to be measured with conventional measuring tools, and a pin gauge can only be used instead of a conventional measuring tool. The pin gauge is a round rod with a specific size and high hardness made of stainless steel, tool steel, ceramic, tungsten steel, bearing steel or other materials, which is suitable for measuring the width of the bending slot. However, since the blade slot interval height is 33.5mm, the length of the pin gauge of suitable size is 50mm. In order to avoid interference between the pin gauge and the blade slot, the method adopted is to cut the pin gauge shorter. However, the shortened pin gauge has a small diameter and short length. Direct handheld measurement usually results in low measurement efficiency and unstable measurement due to factors such as hand slippage. In addition, the pin gauge will be affected by changes in hand temperature, resulting in thermal expansion, which further increases the measurement error. Utility Model Content

[0003] In response to the above-mentioned drawbacks, the present invention aims to provide a pin gauge clamp for measurement. The device fixes the pin gauge through the clamp body, which not only solves the blade slot measurement problem but also improves the measurement accuracy.

[0004] In order to achieve the above technical objectives, the following technical solutions are adopted:

[0005] A pin gauge clamp for measuring includes a clamp body, wherein clamping ends are respectively provided at both ends of the clamp body, and the clamping ends are provided with elongated elastic grooves. The elastic grooves are connected to a circular mounting groove for accommodating a pin gauge at the outward end. The mounting groove is open outward and a threaded hole passing through the clamping end is provided on the lower side of the mounting groove, and a locking screw matching the threaded hole is provided in the threaded hole.

[0006] Furthermore, the through-end needle gauge and the stop-end needle gauge are oriented in opposite directions.

[0007] Furthermore, a notch is provided on the end surface of the clamping end for accommodating the through-end needle gauge, for distinguishing the through-end needle gauge from the stop-end needle gauge.

[0008] Furthermore, the letter "T" is engraved on the end of the clamping end that accommodates the through-end needle gauge, and the letter "Z" is engraved on the end of the clamping end that accommodates the stop-end needle gauge to distinguish between the through-end needle gauge and the stop-end needle gauge.

[0009] Furthermore, the locking screw is a hexagon socket head screw.

[0010] Furthermore, the clamp body is a rectangular parallelepiped that is easy to hold in hand.

[0011] The beneficial effects achieved by the utility model are:

[0012] Compared to existing technologies, the present invention utilizes a rectangular clamp to secure the through-end and stop-end gauges at their respective ends, which are then secured with locking screws. This handheld clamp eliminates the issues of slippage during measurement after shortening the gauge and the gauge's temperature being affected. By placing both the through-end and stop-end gauges simultaneously on the clamp, measurements can be made simply by rotating the gauge clamp, making testing more convenient and eliminating the need to repeatedly remove the gauges. Consequently, the present invention's gauge clamp improves measurement accuracy and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The embodiments described are merely a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0020] like Figure 1-3 As shown, a measuring needle gauge clamp of the present invention includes a clamp body 1, a needle gauge 2 and a locking screw 3.

[0021] The clamp body 1 is a rectangular structure that is easy to hold by hand, and is provided with a clamping end 10 at each end. The clamping end 10 is provided with a long elastic groove 110, and the elastic groove 110 is connected to a circular mounting groove 120 at the outward end. The mounting groove 120 is open to the outside and has a threaded hole 130 passing through the clamping end 10 on the side below the mounting groove 120. A locking screw 3 that matches it is provided in the threaded hole 130.

[0022] There are two needle gauges 2, which are respectively accommodated in the mounting grooves 120 at both ends of the fixture body 1, wherein one end is a through-end needle gauge 21 and the other end is a stop-end needle gauge 22; the through-end needle gauge 21 and the stop-end needle gauge 22 face opposite directions for easy detection.

[0023] The locking screw 3 is matched with the threaded hole 130 on the clamp body 1 and is a hexagon socket head screw used to lock the needle gauge 2.

[0024] In order to facilitate the distinction between the through-end needle gauge 21 and the stop-end needle gauge 22, a notch 140 is provided on the end face of the clamping end 10 that accommodates the through-end needle gauge 21; it is also possible to engrave the letter "T" on the end body of the clamping end 10 that accommodates the through-end needle gauge 21, and engrave the letter "Z" on the end body of the clamping end 10 that accommodates the stop-end needle gauge 22.

[0025] The working principle of this utility model is:

[0026] Place the through-end needle gauge 21 and the stop-end needle gauge 22 in opposite directions in the mounting groove 120 on the clamping end 10 of the fixture body 1, and use the locking screw 3 to pass through the corresponding threaded hole 130 and tighten the locking screw 3. The locking force of the locking screw 3 will press the elastic groove 110 and the mounting groove 120 toward the outer circle of the needle gauge 2, thereby locking the through-end needle gauge 21 and the stop-end needle gauge 22, and then they can be used to detect the blade groove size. When using, if Figure 4 As shown, it is only necessary to rotate the fixture body 1 to select whether to use the through-end needle gauge 21 or the stop-end needle gauge 22 for measurement.

[0027] The needle gauge clamp of this utility model is universal. It can complete the measurement of blade slots of different sizes by simply replacing the needle gauge. The simple structure and easy operation solve the problem of blade slots being too small to measure, while also ensuring the accuracy and efficiency of the measurement.

[0028] Other aspects of the present invention that are not described in detail are all conventional technologies known to those skilled in the art.

[0029] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or elements that are inherent to such process, method, article, or apparatus.

Any modifications, equivalent replacements, improvements, etc. made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
