Description

Technical Field

[0001] This utility model relates to the field of height difference detection technology, specifically to a measuring device for measuring the height difference of components in a new energy battery box. Background Technology

[0002] In the automotive battery box manufacturing industry, it is usually necessary to measure the height difference of parts to meet assembly quality requirements. For example, the mounting sleeve is one of the parts that must be measured after it is installed on the battery box, as it determines whether the battery can be stably installed on the car.

[0003] After the mounting sleeve is installed on the battery box, a ring-shaped boss will protrude from the surface of the battery box. To ensure that the mounting sleeve is installed properly, a height difference test of the ring-shaped boss is required.

[0004] In existing technologies, height difference detection is often performed using an "L"-shaped measuring block. Specifically, the measuring block is placed vertically on the surface of the battery box in the pattern of the number "7". The installation of the mounting sleeve is determined by observing whether the horizontal plane of the measuring block is in contact with the top of the mounting sleeve.

[0005] However, in actual operation, due to the structure of the measuring block itself, it cannot be placed stably on the surface of the battery box and is prone to tipping over. Secondly, the cross-sectional dimension of the measuring block in the horizontal direction is smaller than the cross-sectional dimension of the top of the mounting sleeve. For the same mounting sleeve, the direction of the measuring block needs to be adjusted multiple times to ensure more accurate measurement. When measuring in a certain direction, a gap appears between the measuring block and the top of the mounting sleeve, and a feeler gauge needs to be inserted for further inspection. The whole operation process is very time-consuming and laborious. Utility Model Content

[0006] In view of this, the present invention provides a measuring device for measuring the height difference of parts in a new energy battery box, which aims to detect the height difference of parts more quickly and conveniently.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A measuring device for measuring the height difference of components in a new energy battery box, characterized in that: it includes a cylindrical body with an open lower end for mounting space, the cylindrical body being used to cover the component to be tested; a measuring pad capable of sliding up and down within the mounting space is provided inside the cylindrical body; a dial indicator is provided at the top of the cylindrical body, the measuring rod of the dial indicator extending downward through the mounting space and positioned above the measuring pad; during the process of the cylindrical body covering the component to be tested, the measuring pad is forced to slide upward by the obstruction of the component to be tested, and pushes the measuring rod upward synchronously.

[0009] Using the above structure, during the process of the cylinder covering the part to be tested, the highest point of the part can first contact the bottom surface of the measuring pad. The resistance of the part to be tested can force the measuring pad and the testing rod to move upward synchronously. When the cylinder is completely covering the part to be tested, the bottom surface of the measuring pad is the surface where the highest point of the part to be tested is located. By comparing the data measured by the dial indicator with the data parameters of the part under standard installation conditions, it can be determined whether there is a height difference in the part to be tested and by how much. Compared with the traditional line segment detection using an "L"-shaped measuring block, using a dial indicator to detect the surface where the highest point of the part to be tested is located is not only simple to operate, but also provides more intuitive detection data.

[0010] Preferably, the top center of the cylinder has a mounting hole that connects downwards to the mounting space. A linear bearing is installed inside the mounting hole, and a sliding support shaft is installed inside the linear bearing. The lower end of the support shaft is fixedly connected to the center of the measuring pad. With this structure, the cooperation of the linear bearing and the support shaft ensures stable vertical movement of the measuring pad, preventing it from tipping over due to height differences in the parts being tested. This ensures that when the measuring pad contacts the part being tested, the bottom surface of the measuring pad is always at the highest point of the part being tested.

[0011] Preferably, the measuring pad is adapted to the cross-sectional dimensions of the mounting space. This structure ensures that the top of the part to be tested is completely placed under the measuring pad, thereby guaranteeing the accuracy of the test.

[0012] Preferably, the measuring pad is made of a rigid material and has a thickness of 10 mm. This structure ensures the accuracy of the dial indicator measurement.

[0013] Preferably, the bottom surface of the measuring pad is parallel to the bottom surface of the cylinder. This structure ensures that when the measuring pad contacts the part to be tested, the bottom surface of the measuring pad is the plane containing the highest point of the part.

[0014] Preferably, the dial indicator is fixedly mounted on the top of the cylinder using a mounting bracket. This structure allows the dial indicator to be positioned correctly, facilitating the use of the testing device.

[0015] Preferably, a limiting block is provided at the lower end of the inner cavity of the cylinder, and the lower end of the measuring pad can abut against the top of the limiting block. This structure allows the entire detection device to be designed as a single unit, thus facilitating its use.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The measuring device provided by this utility model for measuring the height difference of new energy battery box parts allows the highest point of the part to contact the bottom surface of the measuring pad first during the process of the cylinder covering the part to be tested. The resistance of the part to be tested forces the measuring pad and the measuring rod to move upward synchronously. When the cylinder completely covers the part to be tested, the bottom surface of the measuring pad is the surface where the highest point of the part to be tested is located. By comparing the data measured by the dial indicator with the data parameters of the part under standard installation conditions, it can be determined whether there is a height difference and how much the height difference is. Compared with the traditional line segment detection using an "L"-shaped measuring block, using a dial indicator to detect the surface where the highest point of the part to be tested is located is not only simple to operate, but also provides more intuitive detection data. Attached Figure Description

[0018] Figure 1 This is a cross-sectional view of the height difference measuring device.

[0019] Figure 2 This is a reference diagram showing the actual usage of the height difference measuring device. Detailed Implementation

[0020] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0021] This embodiment uses the detection of the mounting sleeve 6 as an example for illustration. Figure 2 As shown, the mounting sleeve 6 is fixedly mounted on the box frame 7.

[0022] A measuring device for measuring the height difference of components in a new energy battery box includes a cylinder 1 with an open mounting space 1a at the lower end. When measuring the height difference, the lower end of the cylinder 1 is close to the top of the box frame 7. At this time, the mounting sleeve 6 can be placed inside the mounting space 1a. A measuring pad 2 that can slide up and down in the mounting space 1a is installed inside the cylinder 1. A dial indicator 3 is installed on the top of the cylinder 1. The measuring rod 3a of the dial indicator 3 extends downward through the mounting space 1a and is located above the measuring pad 2.

[0023] During the process of the cylinder 1 covering the mounting sleeve 6, the top of the mounting sleeve 6 will first come into contact with the bottom surface of the measuring pad 2. Due to the obstruction of the mounting sleeve 6, the measuring pad 2 and the detection rod 3a can move upward synchronously. When the bottom of the cylinder 1 is completely in close contact with the surface of the box frame 7, the bottom surface of the measuring pad 2 corresponds to the plane where the highest point of the mounting sleeve 6 is located. By comparing the data measured by the dial indicator 3 with the height difference parameter measured under the standard installation state of the mounting sleeve 6, it can be determined whether there is a height difference in the mounting sleeve 6 and what the specific value of the height difference is. Compared with the traditional line segment detection using the "L" shaped measuring block, the dial indicator 3 can detect the plane where the highest point of the mounting sleeve 6 is located. The whole detection process is not only simple to operate, but also the detection data is more intuitive.

[0024] Specifically, a mounting hole 1b is formed at the middle of the top of the cylinder 1, which connects downward to the mounting space 1a. A linear bearing 4 is fixedly installed inside the mounting hole 1b, and a support shaft 5 that can slide up and down passes through the linear bearing 4. The lower end of the support shaft 5 is fixedly connected to the middle of the measuring pad 2. Through the cooperation of the linear bearing 4 and the support shaft 5, the measuring pad 2 can be stably moved up and down within the mounting space 1a. The measuring pad 2 will not tilt along with the mounting sleeve 6 due to the height difference, thus ensuring that when the measuring pad 2 is in contact with the mounting sleeve 6, the bottom surface of the measuring pad 2 is always the surface where the highest point of the mounting sleeve 6 is located.

[0025] In this embodiment, the measuring pad 2 is adapted to the horizontal cross-sectional dimensions of the installation space 1a, so as to ensure that the top surface of the mounting sleeve 6 can be completely placed inside the bottom surface of the measuring pad 2, thereby ensuring that when the measuring pad 2 contacts the mounting sleeve 6, the contact point is the highest point of the mounting sleeve 6.

[0026] Furthermore, the bottom surface of the measuring pad 2 is set parallel to the bottom surface of the cylinder 1, so as to ensure that the measuring pad 2 can be set parallel to the surface of the box frame 7, thereby ensuring that when the measuring pad 2 contacts the mounting sleeve 6, the contact point is the highest point of the mounting sleeve 6.

[0027] In this embodiment, the measuring pad 2 is made of a rigid material, which can be hard plastic or metal. In this embodiment, the thickness of the measuring pad 2 is set to 10mm. This design can ensure the accuracy of the dial gauge 3 measurement.

[0028] like Figure 1 As shown, the dial gauge 3 is fixedly installed on the top of the cylinder 1 by the mounting bracket 3b. In this embodiment, the bottom end of the detection rod 3a is suspended on the top surface of the measuring pad 2. In addition, the bottom end of the detection rod 3a can also be in contact with the top surface of the measuring pad 2. At this time, the blocking effect of the hanging sleeve 6 forces the measuring pad 2 to move upward, which can immediately drive the detection rod 3a to move upward.

[0029] like Figure 1 As shown, a limiting block 1c is formed at the lower end of the inner side of the cylinder 1. The lower end of the measuring pad 2 can abut against the top of the limiting block 1c. Through the limiting block 1c, the cylinder 1 and the measuring pad 2 can be connected as one unit, which facilitates the use of the measuring device.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
