Description

Technical Field

[0001] This utility model belongs to the field of testing tooling technology, specifically relating to a rapid testing tooling for hole-to-edge distance. Background Technology

[0002] In fields such as machinery manufacturing and parts processing, the distance from irregularly shaped holes on parts to their edges is an important indicator for measuring the machining accuracy and assembly performance of parts. Its test results directly affect the accuracy of subsequent assembly and the overall quality of the product.

[0003] Currently, the conventional method for detecting the distance from irregularly shaped holes to the edge is as follows: the part is fixed on a horizontal plane with the edge as a reference, a mandrel is inserted into the hole to simulate the center position of the hole, and then the height of the mandrel is measured with a height gauge. The distance from the hole to the edge is calculated.

[0004] However, this detection method has obvious shortcomings:

[0005] 1. The operation process is cumbersome, requiring multiple adjustments to the fixed position of the parts to ensure accurate reference, and the process of inserting the mandrel also requires repeated calibration, which consumes a lot of time.

[0006] 2. The measurement process relies on manual operation of a height gauge, which is not only labor-intensive, but also prone to affecting the accuracy of the measurement due to human reading errors and differences in operating techniques.

[0007] 3. For mass-produced parts, the detection efficiency of this method is extremely low, making it difficult to meet the rapid quality inspection needs of modern production lines.

[0008] Therefore, in order to solve the problems of existing detection methods being cumbersome, inefficient, and easily affected by human factors, developing a tooling that can quickly and accurately detect the distance from irregularly shaped holes to the edge has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0009] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a rapid detection fixture for hole-to-edge distance.

[0010] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0011] A rapid detection fixture for hole-to-edge distance includes a substrate on which a marker post, a battery box, and a mounting block are mounted.

[0012] The battery box is equipped with a negative terminal contact strip, a positive terminal contact strip, and two indicator lights;

[0013] The mounting block is equipped with a pressure gauge, and two straight rods are slidably mounted on the mounting block. The lower ends of the two straight rods are connected to a movable box. A spring is installed between the mounting block and the movable box, and the spring is sleeved on the outside of the straight rods.

[0014] A positive electrode plate is installed on the top of the mobile box, and the positive electrode plate is electrically connected to the positive electrode contact strip. Two top columns are slidably installed in the mobile box, and a negative electrode plate is installed on the top of each of the two top columns. Both negative electrode plates are electrically connected to the negative electrode contact strip.

[0015] Furthermore, the side of the mobile box is equipped with copper contacts, which are electrically connected to the positive electrode plate and the positive electrode contact strip.

[0016] Furthermore, the battery box contains two AA batteries.

[0017] Further specifying, the back side of the mobile box is provided with two sliding grooves, and the negative electrode plate is located in the sliding grooves.

[0018] Further specifying, the movable box is provided with a guide tube inside, and the top column is located in the guide tube.

[0019] The beneficial effects of using this utility model are as follows:

[0020] Once the standard is established, this utility model allows for the direct and repeated insertion of components into the gauge post. By observing the data on the pressure gauge, it is possible to determine whether the components are qualified. This method is simple, convenient, and quick, while also having low technical requirements, low strength, and high efficiency. Because the judgment is made by reading the pressure gauge, the probability of human error is small, and the probability of incorrect judgment is also low. Attached Figure Description

[0031] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] Example 1:

[0033] like Figures 1-4 As shown, a rapid detection fixture for hole-to-edge distance according to the present invention includes a base plate 1, on which a marker post 2, a battery box 3 and a mounting block 4 are mounted.

[0034] The battery box 3 is equipped with a negative terminal contact strip 31, a positive terminal contact strip 32, and two indicator lights 33;

[0035] The mounting block 4 is equipped with a pressure gauge 41. Two straight rods 42 are slidably mounted on the mounting block 4. The lower ends of the two straight rods 42 are connected to a movable box 43. A spring 44 is installed between the mounting block 4 and the movable box 43. The spring 44 is sleeved on the outside of the straight rods 42.

[0036] A positive electrode plate 431 is installed on the top of the mobile box 43. The positive electrode plate 431 is electrically connected to the positive electrode contact strip 32. Two top posts 432 are slidably installed in the mobile box 43. A negative electrode plate 433 is installed on the top of each of the two top posts 432. Both negative electrode plates 433 are electrically connected to the negative electrode contact strip 31.

[0037] In this implementation case, before testing, the specifications of the marker 2 need to be determined and the zero position is aligned using a standard block, which serves as the standard for subsequent testing. This operation is a commonly used method in the existing technology and is not difficult for those skilled in the relevant field to understand and use.

[0038] After the standard is established, the hole of the test piece is placed outside the scale post 2, and then the edge is moved close to the top post 432. When both top posts 432 are in contact, observe the data on the pressure gauge 41. If it is zero or within the allowable tolerance range, it indicates that it is qualified; otherwise, it indicates that it is unqualified.

[0039] Regarding the question of whether the two top posts 432 are in correct contact, skilled personnel may be able to quickly identify this, while less skilled personnel may not be able to grasp it well. Therefore, a battery can be installed in the battery box 3. With the power supply of the battery, when the top post 432 is in correct contact, its installed negative plate 433 will contact the positive plate 431, thus forming a circuit. The corresponding indicator light 33 will light up, and the inspector can judge the accuracy of the position by reading the indicator light 33. When both indicator lights 33 are lit, the reading on the pressure gauge 41 can be read.

[0040] Example 2:

[0041] like Figure 1 , Figure 3 As shown, copper contacts 434 are installed on the side of the mobile box 43, and the copper contacts 434 are electrically connected to the positive plate 431 and the positive contact strip 32.

[0042] In this embodiment, the positive plate 431 is first connected to the copper contact 434, and the connection between the copper contact 434 protruding from the movable box 43 and the positive contact strip 32 becomes more convenient. Moreover, when connecting, there is no need to open the movable box 43, which is conducive to the disassembly and maintenance of the battery box 3.

[0043] Example 3:

[0044] like Figure 1 As shown, battery box 3 contains two AA batteries.

[0045] In this implementation case, AA batteries are common batteries, and they have strong power supply and battery life, ensuring their service life.

[0046] Example 4:

[0047] like Figure 2 , Figure 4 As shown, the back side of the mobile box 43 is provided with two sliding grooves 435, and the negative electrode plate 433 is located in the sliding grooves 435.

[0048] In this embodiment, the electrical connection point is led out of the movable box 43 without affecting the movement of the top column 432. The way the electrical connection point is led out makes it easy to complete the connection of the wires without disassembling the movable box 43.

[0049] Example 5:

[0050] like Figure 1 As shown, the movable box 43 is equipped with a guide tube 436 inside, and the top column 432 is located in the guide tube 436.

[0051] In this embodiment, the guide tube 436 can limit the movement of the top post 432 to prevent axial displacement, while also limiting the distance between the negative electrode plate 433 and the positive electrode plate 431 on the top post 432, ensuring that contact does not require a long distance of movement.

[0052] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
