Description

Technical Field

[0001] This utility model belongs to the technical field of measuring instruments for irregularly shaped heads, and in particular, it is a measuring instrument for irregularly shaped heads. Background Technology

[0002] Irregular-shaped heads refer to non-standard heads that differ from standard heads (such as elliptical, spherical, dish-shaped, and other regular geometric shapes). Their core characteristic is that they are designed and manufactured in a personalized manner according to the structural, functional, or operating requirements of specific equipment.

[0003] Inspection gauges for irregular-shaped heads refer to specialized tools or devices used to measure and inspect the geometric dimensions, shape deviations, and key characteristic parameters of non-standard (irregular-shaped) heads. Existing inspection gauges for irregular-shaped heads generally measure key parameters such as depth, radius of curvature, profile, port flatness, and local concavity and convexity of irregular-shaped heads, and determine whether they meet the design tolerance requirements.

[0004] After the end caps are manufactured, their depth needs to be measured. Currently, the traditional method for measuring the depth of end caps is to use a full template. Different specifications of end caps require the creation of templates of different specifications for measuring their shape and dimensions. At the same time, when using existing measuring tools for irregular-shaped end caps to measure the depth, the depth must be measured at different positions. Since the measuring tools generally use a full template for measurement, when it is necessary to measure the depth at different angles, templates of different angles need to be made for measuring the shape and dimensions, which leads to a decrease in work efficiency.

[0005] The purpose of this invention is to provide a measuring tool for irregularly shaped heads to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a measuring tool for irregularly shaped heads to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a measuring tool for irregularly shaped heads, comprising a first ruler and a second ruler; The first ruler has slide rails on both sides, and slide plates are provided in both slide rails. The two slide plates are connected by an adjustment mechanism. The adjustment mechanism is equipped with a second ruler and a limit mechanism. One of the slide plates has multiple limit holes. After the limiting rod in the limiting mechanism moves upward and disengages from its limiting hole, the spring in the limiting mechanism will be stretched. At the same time, when the rotating shaft in the adjusting mechanism is driven to rotate, the second ruler rotates synchronously with the rotating shaft.

[0008] Furthermore, after the limiting rod is inserted into the corresponding limiting hole by the spring return of each spring, the rotating shaft and the second ruler on the rotating shaft are fixed, which facilitates the stability of the second ruler during measurement.

[0009] Furthermore, the adjustment mechanism includes a pivot and a handle. A pivot is provided between the two slides, and a handle is provided at the upper end of the pivot. A second ruler is provided on the pivot and is located between the two slides to facilitate multi-angle adjustment of the second ruler.

[0010] Furthermore, the limiting mechanism includes a limiting rod, a baffle, and a spring. The grip is provided with a limiting rod, and the upper end of the limiting rod is provided with a baffle. The baffle and the grip are connected by multiple springs to facilitate the fixing of the second ruler.

[0011] Furthermore, one of the slide plates has multiple limiting holes circumferentially centered on the pivot shaft at its upper end, and the limiting rod can be located in any of the limiting holes, which facilitates fixing by using a second ruler at different angles.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes an adjustment mechanism positioned between two sliding plates and a limiting mechanism on the handle. A baffle moves outward, pulling the limiting rod outward as well, simultaneously stretching each spring until the limiting rod disengages from its corresponding limiting hole. Next, the handle rotates, causing a connected shaft to rotate, which in turn rotates a connected second ruler until it reaches a suitable angle. This allows for the measurement of depths at different angles, solving the problem in the prior art where measuring depths at different angles required creating templates of different angles, leading to reduced work efficiency.

[0016] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0017] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0018] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0019] Please see Figures 1 to 3 As shown, this utility model provides a measuring tool for irregularly shaped heads, including a first ruler 1 and a second ruler 5, which are used to provide a first support for measuring the diameter of the head, and the second ruler 5 for measuring the depth of the head.

[0020] The first ruler 1 has slide rails 2 on both sides to ensure the stable sliding of the two slide plates 3. Each slide rail 2 has a slide plate 3. The two slide plates 3 are connected by an adjustment mechanism 4. The adjustment mechanism 4 has a second ruler 5 and a limit mechanism 6. One of the slide plates 3 has multiple limit holes 7. After the limiting rod 601 in the limiting mechanism 6 moves upward and disengages from the limiting hole 7, the spring 603 in the limiting mechanism 6 will complete its stretching. At the same time, when the rotating shaft 401 in the adjusting mechanism 4 is driven to rotate, the second ruler 5 will rotate synchronously with the rotating shaft 401. After the limiting rod 601 is inserted into the corresponding limiting hole 7 by the spring 603, the rotating shaft 401 and the second ruler 5 on the shaft are fixed. It is used to move outward through the baffle 602 and move the limiting rod 601 outward, while stretching each spring 603 until the limiting rod 601 disengages from the limiting hole 7. Then, the handle 402 is rotated, which causes the connected rotating shaft 401 to rotate. When the rotating shaft 401 rotates, it causes the connected second ruler 5 to rotate until the second ruler 5 is rotated to a suitable angle, thereby achieving the measurement of depth at different angles. It can effectively and quickly measure the depth of the end cap at different angles, thereby improving work efficiency. The adjustment mechanism 4 includes a rotating shaft 401 and a handle 402. The rotating shaft 401 is provided between the two slide plates 3, which is used to rotate the second ruler 5. The handle 402 is provided at the upper end of the rotating shaft 401, which is used to increase the friction when the operator holds the hand, thereby ensuring the stability during rotation. The second ruler 5 is provided on the rotating shaft 401, and the second ruler 5 is located between the two slide plates 3. The limiting mechanism 6 includes a limiting rod 601, a baffle 602, and a spring 603. The grip 402 is provided with a limiting rod 601, which is used to fix the position of the second ruler 5 by inserting the limiting rod 601 into the corresponding limiting hole 7. The upper end of the limiting rod 601 is provided with a baffle 602, which is used to prevent the limiting rod 601 from entering the grip 402 completely, and also to improve the anti-slip effect for the operator. The baffle 602 and the grip 402 are connected by multiple springs 603, which are used to fix the limiting rod 601 when it is inserted into the limiting hole 7. One of the slide plates 3 has multiple limiting holes 7 circumferentially centered on the pivot 401 at its upper end. These holes are used to facilitate fixing the second ruler 5 at any angle. The limiting rod 601 can be located in any of the limiting holes 7.

[0021] Working principle: When it is necessary to measure the depth at other angles, first hold the baffle 602 and move it outward. When the baffle 602 moves outward, it will move the limiting rod 601 outward. At the same time, when the baffle 602 moves, it will stretch each connected spring 603 until the limiting rod 601 is disengaged from the limiting hole 7. Next, grasp the handle 402 and rotate it. When the handle 402 rotates, the connected shaft 401 will rotate. When the shaft 401 rotates, the connected second ruler 5 will rotate until the second ruler 5 is rotated to the appropriate angle. Next, the baffle 602 is released. At this time, each stretched spring 603 rebounds, causing the limit rod 601 to insert into the corresponding limit hole 7. This fixes the angle of the second ruler 5, thereby measuring the depth at different angles.
