Description

Technical Field

[0001] This utility model relates to the field of automatic sampling inspection technology, specifically, it mainly relates to a quality sampling inspection mechanism applied in the automated production of Cartesian coordinate robots. Background Technology

[0002] In the automated production of brake discs, Cartesian coordinate robots can automatically load and unload brake disc parts, mainly used for handling, loading / unloading, and sampling inspection. They achieve precise positioning through linear motion along the X, Y, and Z axes, working in conjunction with a centering gripper to pick up and place brake disc parts, significantly improving production efficiency and automation levels. The quality sampling inspection mechanism, as a crucial component of this process, requires the cooperation of a slide assembly and a centering mechanism to achieve accurate inspection of brake disc parts. However, the structural design of the slide assembly and centering mechanism is critical to ensuring the stability and adaptability of the inspection process. Currently, conventional quality sampling inspection mechanisms have relatively small slide assemblies, only suitable for brake disc parts with a diameter ≤350mm. With the increasing number of brake disc parts in industrial production, this small-sized slide assembly is insufficient to meet inspection requirements, necessitating structural improvements. Meanwhile, the centering mechanism of the existing quality inspection agency is fixed by locking bolts, and the centering mechanism corresponding to each brake disc part is single and independent. In the actual inspection process, when it is necessary to switch brake disc parts, the operator must replace the corresponding centering mechanism. This operation method is not only cumbersome, but also seriously affects the inspection efficiency. This makes it impossible to efficiently adapt brake disc parts of different disc diameters, thus leading to a decrease in inspection efficiency. Utility Model Content

[0011] According to one embodiment of the present invention, the frame includes a main body, four foot brackets, a left sealing plate, a right sealing plate, a rear sealing plate, a bottom plate, an oil receiving plate, a left opening door, a right opening door, and a transition plate; the four foot brackets are located at the bottom of the four corners of the main body, the left sealing plate, the right sealing plate, the rear sealing plate, and the bottom plate are respectively located on the left side, the right side, the rear side, and the bottom of the main body, the oil receiving plate is parallel to the top of the main body and is located at about 1 / 3 of the way from the top, the left opening door and the right opening door are respectively hinged to the left sealing plate and the right sealing plate, the transition plate is located on the top of the main body, and the pneumatic slide rail is located on the transition plate.

[0028] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings:

[0029] like Figure 1 As shown, Figure 1 This is a three-dimensional structural diagram of the quality inspection mechanism in this embodiment. This embodiment provides a quality inspection mechanism applied to automated production using Cartesian coordinate robots, aiming to solve the problems of insufficient adaptability and low switching efficiency of existing conventional inspection mechanisms for large-diameter parts, thereby achieving efficient and accurate inspection of brake disc parts of different specifications. The quality inspection mechanism includes: a frame 1, at least two pneumatic slide rails 2, at least two slide table assemblies 3, and a protective assembly 4; at least two pneumatic slide rails 2 are installed side by side on the top of the frame 1, and each pneumatic slide rail 2 is provided with a slide table assembly 3, so that the slide table assembly 3 can be driven by the pneumatic slide rail 2 to achieve reciprocating movement, thereby completing the automatic transfer and inspection process of brake disc parts; the protective assembly 4 is fixedly connected to the top of the frame 1, and all slide table assemblies 3 are enclosed inside the protective assembly 4. The protective assembly 4 can not only effectively isolate the interference of dust and impurities in the external environment on the inspection process, but also prevent brake disc parts from accidentally falling during the inspection process, significantly improving the safety of equipment operation.

[0030] Please refer to the following: Figure 2 As shown, Figure 2This is a three-dimensional structural diagram of a slide assembly in this embodiment. Each slide assembly 3 includes a slide base plate 31, a centering base 32, and a centering sleeve 33. The slide base plate 31 serves as the basic load-bearing structure and is connected to a corresponding set of pneumatic slide rails 2 to support the brake disc component to be tested. The centering base 32 is fixedly installed on the side of the slide base plate 31 facing away from the pneumatic slide rails 2, and its core function is to provide precise positioning support for the centering sleeve 33. A protrusion 321 is integrally formed at the center of the side of the centering base 32 facing away from the pneumatic slide rails 2, and grooves 331 that are adapted to the protrusion 321 are respectively formed at both ends of the centering sleeve 33. During assembly, the protrusion 321 on the centering base 32 extends into the groove 331 at one end of the centering sleeve 33. Through this tight fitting structure of "protrusion-groove", the centering sleeve 33 can be stably installed. This design effectively prevents the slide assembly from shifting during slide movement, allowing it to stably accommodate brake disc parts with diameters exceeding 350mm. This overcomes the limitations of traditional mechanisms on brake disc part dimensions. Furthermore, the use of a boltless "protrusion-groove" fitting structure replaces the traditional locking bolt method. When switching between different brake disc parts for testing, only the centering sleeve 33 adapted to the different brake disc parts needs to be replaced; there is no need to replace the entire centering base 32 and centering sleeve 33, significantly simplifying the operation and improving testing efficiency. Moreover, the diameter of the centering sleeve 33 is designed to be smaller than that of the centering base 32. This size combination allows the centering sleeve 33 to be fully supported by the centering base 32, further enhancing the overall structural stability. This allows for the replacement of centering sleeves 33 with corresponding diameters within the specified range, making the process highly efficient and convenient.

[0031] Furthermore, the slide assembly 3 also includes multiple fixing pins 34, a mounting bracket 35, and a proximity sensor 36. The multiple fixing pins 34 are evenly arranged on the slide base plate 31 around the centering base 32. These fixing pins 34 can simulate the positioning function of the centering claw, and provide auxiliary clamping and positioning from multiple points on the outer periphery of the brake disc part to prevent the part from shifting laterally during detection or movement. A part material groove 311 is provided between each pair of fixing pins 34 on the slide base plate 31. Its shape is adapted to the outer contour of the brake disc part to be detected, further improving the positioning accuracy. The mounting bracket 35 is located on the slide base plate 31 near the outer side of one of the part material grooves 311. The proximity sensor 36 passes through the mounting bracket 35 and is located inside the part material groove 311. It can detect whether the brake disc part is in place in real time and provide signal feedback for automated detection.

[0032] Please refer to the following: Figure 3 As shown, Figure 3This is a cross-sectional schematic diagram of the usage scenario between the centering base and the centering sleeve in this embodiment. To further improve the connection stability between the centering base 32 and the centering sleeve 33, the protrusion 321 on the centering base 32 is provided with several friction stripes 320 evenly distributed axially in the vertical direction. Correspondingly, the inner walls of the grooves 331 at both ends of the centering sleeve 33 are also provided with friction stripes 320 that match the friction stripes 320 on the protrusion 321. When the centering base 32 and the centering sleeve 33 are engaged, the two sets of friction stripes 320 mesh with each other, significantly increasing the static friction of the contact surface. Even if the equipment experiences severe vibration or frequent start-stop during high-speed operation, it can effectively prevent the centering sleeve 33 from axially shifting or radially deviating, fundamentally avoiding accidental detachment during the testing process and providing continuous and stable support for part positioning.

[0033] Furthermore, the diameter of the protrusion 321 and the diameter of the grooves 331 at both ends of the centering sleeve 33 are precisely calculated and machined. This zero-dimensional design ensures that the contact surfaces fit evenly when the two are engaged, with the gap controlled within a minimum range, effectively avoiding installation misalignment caused by dimensional deviations. At the same time, the height of the protrusion 321 is precisely designed to be slightly smaller than the height of the groove 331, usually leaving a corresponding assembly gap. This gap does not affect the connection strength between the two, and provides sufficient operating space for the installation and removal of the centering sleeve 33. Operators can easily and quickly pick up and put down the centering sleeve 33 without the need for special tools, significantly reducing the operational difficulty during the replacement process.

[0034] Furthermore, a central hole 332 penetrating the entire sleeve is provided between the grooves 331 at both ends of the centering sleeve 33. The inner diameter of the central hole 332 is strictly controlled to be smaller than the diameter of the grooves 331 at both ends, typically 1 / 3 to 1 / 2 of the diameter of the grooves 331. The central hole 332 can significantly reduce the overall weight of the centering sleeve 33 while ensuring its structural strength, thereby reducing the load on the slide assembly 3 during movement, reducing the driving force consumption of the pneumatic slide rail 2, and improving the operating efficiency of the equipment. Secondly, for some special-shaped parts with shaft-like protrusions or requiring center positioning, the central hole 332 can serve as a precise positioning reference, enabling rapid calibration of the part's center position in conjunction with an external detection device, further expanding the equipment's adaptability to different types of brake disc parts.

[0035] like Figure 4 As shown, Figure 4This is a three-dimensional structural diagram of a pneumatic slide rail in this embodiment. Each pneumatic slide rail 2 includes a pneumatic drive cylinder 21 and two slide rail bodies 22. The pneumatic drive cylinder 21 and the two slide rail bodies 22 are arranged parallel to each other on the top of the frame 1. The two slide rail bodies 22 are respectively arranged on both sides of the pneumatic drive cylinder 21. This parallel arrangement can ensure the straightness of the movement of the slide assembly 3 and avoid the impact of movement trajectory deviation on the detection accuracy. The slide rail bodies 22 distributed on both sides can balance the force on the slide assembly 3 and reduce the shaking during the movement. One side of the bottom of the slide base plate 31 is fixed to the moving end of the pneumatic drive cylinder 21, and the other side is slidably connected to the two slide rail bodies 22. The pneumatic drive cylinder 21 provides power output, and the slide rail bodies 22 guide the movement direction. The two work together to achieve smooth and efficient movement of the slide assembly 3.

[0036] Furthermore, each slide rail body 22 includes a slide rail 221 and two sliding connecting blocks 222. The slide rail 221 is fixed to the top of the frame 1 by screws, serving as the basic track for sliding movement. The two sliding connecting blocks 222 are spaced apart on the slide rail 221 and can slide freely along the length of the slide rail 221. The bottom of the slide table base plate 31 is fixedly connected to the two sliding connecting blocks 222. The pressure of the slide table base plate 31 is distributed by the two sliding connecting blocks 222, reducing single-point wear and improving the stability of sliding.

[0037] The pneumatic drive cylinder 21 includes a cylinder 211, a limit sensor 212, and a fixed connecting block 213. The cylinder 211 is fixed to the top of the frame 1 by bolts and serves as a power source to provide reciprocating driving force to the slide assembly 3. The limit sensor 212 is installed at one end of the cylinder 211 and is used to detect the moving position of the slide assembly 3. When the slide assembly 3 moves to a preset limit position, the limit sensor 212 will send a signal to control the cylinder 211 to stop moving and prevent the slide assembly 3 from overtraveling. The fixed connecting block 213 is fixed on the side of the limit sensor 212 facing the slide assembly 3, and the bottom of the slide base plate 31 is fixedly connected to the fixed connecting block 213. The fixed connecting block 213 realizes a rigid connection between the pneumatic drive cylinder 21 and the slide assembly 3, ensuring the stability of power transmission.

[0038] like Figure 5 As shown, Figure 5This is a three-dimensional structural diagram of the frame in this embodiment. The frame 1 includes a main body 10, four foot brackets 11, a left sealing plate 12, a right sealing plate 13, a rear sealing plate 14, a bottom plate 15, an oil receiving plate 16, a left opening door 17, a right opening door 18, and a transition plate 19. The main body 10 is a cubic frame structure, welded from square steel, possessing high strength and rigidity. The four foot brackets 11 are located at the bottom of the four corners of the main body 10. The bottom of the foot brackets 11 is equipped with adjustable screws. By rotating the screws, the levelness of the frame 1 can be adjusted to ensure that the equipment is placed stably. The left sealing plate 12, right sealing plate 13, rear sealing plate 14, and bottom plate 15 are respectively fixed to the left side, right side, rear side, and bottom of the main body 10 by bolts, forming a closed side protection structure, which can effectively prevent external dust and debris from entering the equipment. Additionally, the top 101 is a square frame structure with a blank center, while the oil receiving plate 16 is made of stainless steel plate, parallel to the top 101 of the main body 10 and located at about 1 / 3 of the way from the top 101. Its edges are reinforced to catch oil or coolant dripping from the upper slide assembly 3 during sampling, preventing contamination of the lower structure of the main body 10. The left-opening door 17 and the right-opening door 18 are hinged to the left sealing plate 12 and the right sealing plate 13, respectively. The door panels have observation windows and handles for easy access to parts and observation of equipment operation. The transition plate 19 is located on the top 101 of the main body 10, made of thick steel plate, and its surface is ground to ensure flatness. The pneumatic slide rail 2 is bolted to the transition plate 19, providing a stable mounting base.

[0039] Furthermore, the transition plate 19 includes a left narrow long plate 191, a middle wide long plate 192, a right narrow long plate 193, and at least four transition short plates 194. The left narrow long plate 191, the middle wide long plate 192, and the right narrow long plate 193 are all long strip steel plates, parallel to each other and spaced apart, and are arranged sequentially on the left, middle, and right sides of the top 101, with their upper surfaces remaining at the same horizontal plane. The four transition short plates 194 are all fixed to the top 101 by welding and are perpendicular to the left narrow long plate 191, the middle wide long plate 192, and the right narrow long plate 193. The four transition plates 194 are evenly divided into two pairs. One pair of transition plates 194 is located between the left narrow long plate 191 and the middle wide long plate 192, while the other pair is located between the middle wide long plate 192 and the right narrow long plate 193. In each pair of transition plates 194, one transition plate 194 faces the other, and the spacing is adapted to the width of the pneumatic drive cylinder 21. The two pairs of transition plates 194 are axially symmetrical about the middle wide long plate 192 to ensure balanced force distribution. The slide rail body 22 on the pneumatic slide rail 2 is bolted to the left narrow long plate 191, the middle wide long plate 192 and the right narrow long plate 193 respectively to ensure the straightness of the slide rail; the pneumatic drive cylinder 21 is located between each pair of transition short plates 194 and is fixed to the transition short plates 194 by bolts. This layout not only ensures the installation stability of each component of the pneumatic slide rail 2, but also reduces the overall weight of the transition plate 19, optimizes the structural stress, and also helps the oil receiving plate 16 below to receive the dripping oil.

[0040] In summary, the quality sampling inspection mechanism of this utility model, by designing the centering sleeve diameter to be smaller than the centering base diameter and adopting a centering sleeve that can be quickly adapted and replaced, can better adapt to the universality of different brake disc parts, thereby significantly improving the efficiency of automated sampling inspection. At the same time, it effectively solves the pain points of the prior art and is suitable for efficient quality inspection in the automated production of Cartesian coordinate robots.
