Description

Technical Field

[0001] This utility model relates to the field of protective structure technology, and in particular to a probe protection structure with anti-collision buffer function. Background Technology

[0002] In precision measurement and automated inspection, probes, as core components for dimensional inspection and positioning, are widely used in various inspection equipment and production lines. Their performance directly determines the accuracy and reliability of the inspection results, playing a crucial role in ensuring product quality. Currently, most common probe structures on the market adopt a direct exposed installation method, meaning the probe's detection end is directly exposed to the outside of the equipment or the working environment. This structural design faces a high risk of damage during practical applications. Because probes typically need to be in close contact with the workpiece being measured or operate under complex conditions, external objects can easily collide directly with the exposed probe during equipment debugging, workpiece loading and unloading, and accidental collisions.

[0003] Because the probe integrates a large number of precision sensing elements and structural components, its impact resistance is relatively weak. Once impacted, it can cause anything from a decrease in sensing element sensitivity and a shift in detection accuracy to severe damage to the internal structure, rendering the probe completely inoperable. Damaged probes not only require downtime for replacement, increasing equipment maintenance costs and downtime, and impacting production efficiency, but also necessitate recalibration and adjustment after replacement, further extending production interruptions and resulting in significant economic losses for the company. Therefore, this invention proposes a probe protection structure with anti-collision buffering function. Utility Model Content

[0004] The purpose of this utility model is to address the problem that commonly used probes on the market are installed in a directly exposed manner, which makes them susceptible to direct impact during equipment debugging, workpiece loading and unloading, etc., resulting in damage to their internal precision components, reduced detection accuracy, or even complete failure, thereby increasing enterprise maintenance costs and downtime and causing economic losses. The present invention proposes a probe protection structure with anti-collision buffer function.

[0005] The technical solution of this utility model is as follows: a probe protection structure with anti-collision buffer function, including a probe body and a mounting box fixedly sleeved on its outer side, the mounting box being hollow; an adjustment mechanism disposed in the mounting box, the adjustment mechanism being sleeved on the outer ring of the probe body for its protection; and a buffer assembly installed on the outer ring of the adjustment mechanism, the buffer assembly being used to buffer external impacts.

[0006] Optionally, the adjustment mechanism includes a fixed cylinder sleeved on the outer ring of the probe body, a movable ring fixedly connected to the top of the fixed cylinder, the movable ring being located inside the mounting box, the movable ring sleeved on the outer ring of the probe body, multiple sets of limiting sleeves installed on the movable ring, a limiting rod slidably connected in the limiting sleeve, and the limiting rod being fixedly connected to the inner wall of the mounting box.

[0007] Optionally, the adjustment mechanism further includes a push rod motor mounted on the top wall of the mounting box, the output end of which is fixedly connected to the moving ring.

[0008] Optionally, the buffer assembly includes a protective cylinder sleeved on the outer ring of the fixed cylinder, and the bottom of the mounting box has a through hole, through which the protective cylinder passes, and the inner diameter of the through hole is larger than the outer diameter of the protective cylinder.

[0009] Optionally, multiple sets of synchronizing blocks are fixedly connected to the top of the protective cylinder. The synchronizing blocks are located on the outside of the protective cylinder and are arranged in a circular array. A sliding rod is slidably connected to each synchronizing block. A movable frame is fixedly connected to both ends of the sliding rod. The movable frame is U-shaped. A slider is fixedly connected to the top of the movable frame. A fixed rod is slidably connected to the slider. The sliding rod and the fixed rod are perpendicular to each other. One end of the fixed rod is fixedly connected to the fixed cylinder.

[0010] Optionally, two sets of first springs are sleeved on the slide rod, with the two sets of first springs located on both sides of the synchronization block.

[0011] Optionally, a limiting plate is fixedly connected to the end of the fixed rod away from the fixed cylinder, and a second spring is sleeved on the outer ring of the fixed rod, the second spring being located between the slider and the limiting plate.

[0012] Optionally, a first rubber plate is fixedly connected to the top of the synchronization block, and a second rubber plate is fixedly connected to the bottom of the moving frame, with the first rubber plate in contact with the second rubber plate.

[0013] In summary, this application includes at least one of the following beneficial technical effects: This utility model, through the setting of the adjustment mechanism, can drive the fixed cylinder to move up and down along the probe body, and precisely adjust its extension length from the bottom of the mounting box. When the probe body is performing testing operations, the protection range can be adjusted to the optimal state without affecting the testing accuracy according to the size of the workpiece being tested and the testing scenario. In non-testing state or during handling and debugging, the extension length of the fixed cylinder can be extended to expand the protection area, thereby improving the versatility and practicality of the protection structure. Furthermore, through the setting of protective components, when the protective cylinder is subjected to external impact, the first and second springs on the mutually perpendicular sliding rod and the fixed rod can absorb the impact energy from different directions in all directions through elastic deformation, thereby achieving multi-level buffering; at the same time, the contact friction between the first rubber plate on the synchronization block and the second rubber plate on the moving frame can consume the kinetic energy generated by the spring rebound. In summary, this invention can effectively protect the precision components inside the probe, maintain stable detection accuracy, reduce equipment maintenance costs and downtime, ensure production efficiency, and reduce economic losses for enterprises.

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0017] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Example like Figure 1 and Figure 2 As shown, the probe protection structure with anti-collision buffer function proposed in this utility model includes a probe body 1 and a mounting box 2 fixedly sleeved on its outer side. The mounting box 2 moves synchronously with the probe body 1. The mounting box 2 is hollow and is fixed on the mechanism for moving the probe body 1.

[0022] For further details, please refer to Figure 2 and Figure 3The aforementioned protective structure includes an adjustment mechanism 3 housed in the mounting box 2, which is fitted around the outer ring of the probe body 1 for protection. The adjustment mechanism 3 includes a fixed cylinder 31 fitted around the outer ring of the probe body 1, with a movable ring 32 fixedly connected to the top of the fixed cylinder 31. The movable ring 32 moves synchronously with the fixed cylinder 31. The movable ring 32 is located inside the mounting box 2, fitted around the outer ring of the probe body 1, and has multiple sets of limiting sleeves 33 installed on it. The movable ring 32 moves synchronously with the limiting sleeves 33. A limiting rod 34 is slidably connected within the limiting sleeve 33, and the limiting rod 34 is fixedly connected to the inner wall of the mounting box 2. The position of the limiting rod 34 is fixed, and the movement of the movable ring 32 is smooth due to the limiting effect of the limiting sleeves 33 and the limiting rod 34. The adjustment mechanism 3 also includes a push rod motor 35 installed on the top wall of the mounting box 2. The output end of the push rod motor 35 is fixedly connected to the moving ring 32. After the push rod motor 35 is started, it drives the moving ring 32 to move up and down, thereby driving the fixed cylinder 31 to move synchronously. The extension length of the fixed cylinder 31 from the bottom of the mounting box 2 is adjusted to provide the maximum protection area without affecting the detection effect of the probe body 1.

[0023] Furthermore, such as Figures 2 to 4 As shown, the above-mentioned protective structure also includes a buffer assembly 4 installed on the outer ring of the adjusting mechanism 3. The buffer assembly 4 is used to buffer external impacts. The buffer assembly 4 includes a protective cylinder 41 sleeved on the outer ring of the fixed cylinder 31. The protective cylinder 41 is the first to receive external impacts. A through hole 21 is opened at the bottom of the mounting box 2. The protective cylinder 41 passes through the through hole 21. The inner diameter of the through hole 21 is larger than the outer diameter of the protective cylinder 41, so that the protective cylinder 41 can move without contacting the mounting box 2 after being impacted. Multiple sets of synchronizing blocks 42 are fixedly connected to the top of the protective cylinder 41. The synchronizing blocks 42 move synchronously with the protective cylinder 41. The synchronizing blocks 42 are arranged on the outside of the protective cylinder 41, and the multiple sets of synchronizing blocks 42 are distributed in a ring array. A sliding rod 43 is slidably connected to the synchronization block 42. Moving frames 44 are fixedly connected to both ends of the sliding rod 43. The moving frames 44 are U-shaped. A slider 45 is fixedly connected to the top of the moving frames 44. A fixed rod 46 is slidably connected to the slider 45. The sliding rod 43 and the fixed rod 46 are perpendicular to each other. One end of the fixed rod 46 is fixedly connected to the fixed cylinder 31. Two sets of first springs 47 are sleeved on the sliding rod 43, located on opposite sides of the synchronization block 42. A limiting disc 48 is fixedly connected to the end of the fixed rod 46 away from the fixed cylinder 31. A second spring 49 is sleeved on the outer ring of the fixed rod 46, located between the slider 45 and the limiting disc 48.

[0024] With the first spring 47 and the second spring 49 arranged such that the sliding rod 43 and the fixed rod 46 are perpendicular to each other, when the protective cylinder 41 is impacted, the first spring 47 and the second spring 49 on the compression buffer assembly 4 achieve a buffering effect, preventing direct impact on the fixed cylinder 31 and causing its deformation, thereby preventing the impact from affecting the probe body 1. The top of the synchronization block 42 is fixedly connected to the first rubber plate 410, and the bottom of the moving frame 44 is fixedly connected to the second rubber plate 411. The first rubber plate 410 and the second rubber plate 411 are in contact. Through the friction between the first rubber plate 410 and the second rubber plate 411, and through the cooperation of the first rubber plate 410 and the second rubber plate 411 in the multiple sets of buffer assemblies 4, the elastic force of the first spring 47 and the second spring 49 is prevented from causing reciprocating motion.

[0025] In this embodiment, the push rod motor 35, installed on the top wall of the mounting box 2, is first activated. The output end of the push rod motor 35 drives the movable ring 32, which is fixedly connected to it, to move up and down along the outer ring of the probe body 1. The fixed cylinder 31, which is fixedly connected to the movable ring 32, moves synchronously with it. During this process, multiple sets of limiting sleeves 33 installed on the movable ring 32 slide along the limiting rods 34 fixed to the inner wall of the mounting box 2. Through the cooperation of the limiting sleeves 33 and the limiting rods 34, the movable ring 32 and the fixed cylinder 31 are kept moving smoothly and avoid deviation. By controlling the extension and retraction of the push rod motor 35, the length of the fixed cylinder 31 extending from the bottom of the mounting box 2 can be precisely adjusted, so as to achieve the optimal protection range without interfering with the detection effect of the probe body 1.

[0026] When an external object impacts the device, the protective cylinder 41, fitted around the outer ring of the fixed cylinder 31, first receives the impact and displaces. Multiple sets of synchronizing blocks 42, fixedly connected to the top of the protective cylinder 41, move synchronously with it. These blocks slide along the sliding rod 43, causing the two sets of first springs 47 fitted on the sliding rod 43 to compress or stretch, utilizing the elastic deformation of the springs to initially buffer the impact energy. Simultaneously, the movable frames 44, fixedly connected to both ends of the sliding rod 43, move synchronously with it. The slider 45 at the top of the movable frame 44 slides along the fixed rod 46 fixed to the fixed cylinder 31, compressing the second spring 49 fitted on the fixed rod 46 and further buffering the impact energy. Because the sliding rod 43 and the fixed rod 46 are perpendicular to each other, omnidirectional buffering against impacts at different angles in the horizontal direction can be achieved. In addition, the first rubber plate 410 at the top of the synchronization block 42 contacts the second rubber plate 411 at the bottom of the moving frame 44. The friction between the two consumes the energy generated by the spring rebound, preventing the protective cylinder 41 from reciprocating due to the spring force, avoiding secondary impact on the probe body 1, and ultimately achieving effective anti-collision protection for the probe body 1.

[0027] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
