Description

Technical Field

[0001] This utility model belongs to the field of measuring device technology, and specifically relates to an auxiliary measuring device. Background Technology

[0002] In industrial fields such as machining, equipment installation and maintenance, it is often necessary to measure the height or depth of specific points on workpieces or equipment. Currently, the most commonly used measuring tools are steel rulers and vernier calipers. When using a steel ruler, the ruler must be placed directly against the workpiece being measured, and the measurer's line of sight should be as perpendicular as possible to the scale on the ruler and aligned with the point being measured to take the reading.

[0003] When the measured point is in a dangerous environment such as high temperature, electric, sharp burrs or chemical contamination, close contact by the operator poses a serious safety hazard. Moreover, due to factors such as the angle of sight and the brightness of the light, visual errors are easily generated, affecting the accuracy of the reading.

[0004] While measuring tools such as vernier calipers offer high precision, they still require the jaws to directly contact the potentially dangerous measuring point during measurement. Furthermore, in situations where space is limited or internal depth dimensions need to be read from the side, the use of vernier calipers is extremely inconvenient and readings are difficult. Therefore, we propose an auxiliary measuring device. Utility Model Content

[0005] To address the serious safety hazards posed by close contact between the operator and the measured point in hazardous environments such as high temperature, electrical contact, sharp edges, or chemical contamination, as mentioned in the background, and the inherent visual errors due to factors like line-of-sight angle and lighting conditions that affect reading accuracy, vernier calipers, while highly accurate, still require direct contact between the measuring jaws and the potentially dangerous measured point. Furthermore, their use is extremely inconvenient and difficult in confined spaces or when reading internal depth dimensions from the side. This invention provides an auxiliary measuring device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary measuring device, comprising a base, a standard scale rod, and a fine scale rod. The standard scale rod and the fine scale rod are vertically fixed on the upper end of the base, and a measuring block that can slide along the outer side of the standard scale rod and the fine scale rod is sleeved thereon. A lifting push plate is fixed to one end of the measuring block, and a positioning screw is passed through one side of the lifting push plate. One end of the positioning screw is connected to a limit clamping block through a positioning bearing.

[0007] The measuring block has a mounting groove at one end, and a lifting frame is movably installed in the mounting groove. A magnifying glass is installed in the lifting frame.

[0008] As a preferred auxiliary measuring device of this utility model, a limiting block is fixed at the top of the standard scale rod and the fine scale rod.

[0009] As a preferred auxiliary measuring device of this utility model, the graduation accuracy on the fine graduation rod is higher than that on the standard graduation rod.

[0010] As a preferred auxiliary measuring device of this utility model, the inner side of the limiting clamp is bonded with an anti-slip sheet, and the shape of the limiting clamp matches the outer wall of the standard scale rod. Rotating the positioning screw can drive the limiting clamp to clamp or loosen the standard scale rod.

[0011] As a preferred auxiliary measuring device of this utility model, the clamping surface of the limiting clamp block that contacts the standard scale rod is an arc-shaped surface to increase the contact area and enhance clamping stability.

[0012] As a preferred auxiliary measuring device of this utility model, anti-slip rubber strips are provided on both sides of the mounting groove, and the anti-slip rubber strips are in close contact with both sides of the lifting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This application uses a lockable measuring block as an intermediary to separate the contact of the measuring point from the reading position. After the top of the measuring block contacts the point to be measured, it can be fixed by the positioning screw and the limiting clamp. Then the device can be moved to a safe and comfortable position for reading, avoiding prolonged exposure of the operator's body or eyes to the dangerous measuring environment, greatly ensuring personal safety. The device is equipped with a dual reading system: a standard scale rod for quick coarse reading and a fine scale rod for precise fine reading. Combined with a high-precision scale of 0.1 mm, it can obtain high-precision data, preventing the problems of poor operational safety and difficulty in guaranteeing reading accuracy under certain working conditions caused by the integrated operation of the measuring point and the reading position of existing direct contact measuring tools.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figures 1-4 As shown;

[0023] An auxiliary measuring device includes a base 1, a standard scale rod 2, and a fine scale rod 3. The standard scale rod 2 and the fine scale rod 3 are vertically fixed on the upper end of the base 1. A measuring block 5 that can slide along the outer side of the standard scale rod 2 and the fine scale rod 3 is sleeved thereon. A lifting push plate 6 is fixed to one end of the measuring block 5. A positioning screw 7 is inserted through one side of the lifting push plate 6. One end of the positioning screw 7 is connected to a limit clamping block 8 through a positioning bearing 10. A mounting groove 11 is opened at one end of the measuring block 5. A lifting frame 12 is movably installed in the mounting groove 11. A magnifying glass 13 is installed in the lifting frame 12.

[0024] In this implementation scheme, the locking measuring block 5 serves as an intermediary, achieving separation between the measurement point contact and the reading position. Simply contact the top of the measuring block 5 with the point to be measured, and it can be fixed by the positioning screw 7 and the limiting clamp 8. Subsequently, the device can be moved to a safe and comfortable position for reading, avoiding prolonged exposure of the operator's body or eyes to the dangerous measurement environment, greatly ensuring personal safety. The device is equipped with a dual reading system: the standard scale rod 2 is used for quick coarse reading, and the fine scale rod 3 is used for precise fine reading. Combined with the high-precision scale of 0.1 mm, it can obtain high-precision data.

[0025] In an optional embodiment, a limiting block 4 is fixed to the top of the standard scale lever 2 and the fine scale lever 3.

[0026] In this implementation scheme: the limiting block 4 can effectively prevent the measuring block 5 from accidentally slipping off the top of the standard scale rod 2 and the fine scale rod 3 during the sliding process, thus avoiding the loss or collision damage of the measuring block 5.

[0027] In an optional embodiment, the graduation accuracy on the fine graduation lever 3 is higher than that on the standard graduation lever 2.

[0028] In this implementation plan, the operator can first use the standard scale rod 2 for rapid, wide-range coarse readings at the millimeter level, and then use the fine scale rod 3 for precise readings at the 0.1 millimeter level. This ensures measurement efficiency and achieves high-precision measurement with a single device, eliminating the hassle of changing measuring tools and broadening the application range.

[0029] In an optional embodiment, the inner side of the limiting clamp 8 is bonded with an anti-slip sheet 9, and the shape of the limiting clamp 8 matches the outer wall of the standard scale rod 2. Rotating the positioning screw 7 can drive the limiting clamp 8 to clamp or loosen the standard scale rod 2.

[0030] In this implementation scheme: the anti-slip plate 9 greatly enhances the reliability of locking. When the rotating positioning screw 7 drives the limit clamping block 8 to clamp, the anti-slip plate 9 can generate huge friction force. The matching shape ensures that the clamping force is evenly distributed, thereby firmly fixing the measuring block 5 on the standard scale rod 2 and preventing any displacement when reading.

[0031] In an optional embodiment, the clamping surface of the limiting clamping block 8 that contacts the standard scale rod 2 is an arc-shaped surface to increase the contact area and enhance clamping stability.

[0032] In this implementation scheme: the arc-shaped surface can maximize the contact area with the cylindrical standard scale rod 2, making the clamping force distribution more uniform. This not only significantly enhances the clamping stability and anti-slip effect, but also avoids local wear on the rod wall that may be caused by point contact.

[0033] In an optional embodiment, anti-slip strips 14 are provided on both sides of the mounting groove 11, and the anti-slip strips 14 are in close contact with both sides of the lifting frame 12.

[0034] In this implementation scheme: the friction provided by the anti-slip rubber strip 14 enables the lifting frame 12 to remain stable after being adjusted to a suitable height, preventing the magnifying glass 13 from slipping due to gravity or slight contact, ensuring that it is always in the best observation position, making the process of fine reading convenient and stable, without the need for additional support from the operator.

[0035] Working principle:

[0036] The operator holds the device and places the base 1 stably on the reference plane of the workpiece to be measured. Then, the operator pushes the measuring block 5 up or down so that it slides along the standard scale rod 2 and the fine scale rod 3 until the top of the measuring block 5 contacts the point to be measured.

[0037] After the measuring block 5 is initially positioned, a coarse reading is performed. The operator can quickly read the measurement value accurate to the millimeter level through the scale on the standard scale rod 2, or rotate the positioning screw 7. The rotation of the positioning screw 7 will push the limiting clamp 8 connected to its end through the positioning bearing 10 to move towards the outer wall of the standard scale rod 2. The inner side of the limiting clamp 8 is bonded with an anti-slip plate 9, and its shape matches the outer wall of the standard scale rod 2. When the limiting clamp 8 tightly clamps the standard scale rod 2 under the drive of the positioning screw 7, a huge frictional force will be generated, thereby firmly fixing the measuring block 5 in the current measurement position.

[0038] Then, after the device is fixed, the operator can remove the entire measuring device from the workpiece, especially from the measuring point that may be hot, electrified, or inconvenient to observe, and move it to a safe environment with sufficient light and a comfortable position. The operator can confirm the millimeter-level reading by using the standard scale rod 2, and then focus their gaze on the fine scale rod 3, which is equipped with a precision scale of 0.1 millimeters, allowing the operator to make more precise readings and obtain high-precision measurement values.

[0039] Finally, the operator can lift the lifting frame 12 installed in the mounting slot 11 of the measuring block 5, so that the magnifying glass 13 inside the frame is aligned with the scale line of the fine scale rod 3. By observing through the magnifying glass 13, the scale can be magnified, further reducing visual errors and ensuring accurate readings. The anti-slip rubber strips 14 set on both sides of the mounting slot 11 can provide sufficient friction, so that the lifting frame 12 can be stably maintained at the required height after being lifted and will not slip off by itself.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
