Description

Technical Field

[0001] This utility model relates to the field of equipment assembly, and in particular to a limiting unit and limiting tooling for limiting a sliding pallet. Background Technology

[0002] A three-section slide rail is a precision sliding device composed of an outer rail, a middle rail, and an inner rail nested together. The outer rail, as the fixed rail, has a cross-section with an [-shaped structure and is usually made of cold-rolled steel plate with a thickness of 1.2-1.5mm. The surface is galvanized or chrome-plated, providing strong rust resistance. It is fixed to the cabinet through pre-set screw holes, providing basic support for the entire slide rail. The middle rail, as the transition rail, connects the outer rail and the inner rail. It contains two or three rows of high-precision steel balls, which are separated by a cage to ensure even force distribution during rolling. At the same time, the guide edges on both sides of the middle rail are bent to effectively limit the sliding direction and prevent track deviation. The inner rail is directly connected to the pull-out sliding tray, forming a stable nested structure.

[0003] In the prior art, before assembling the AFD module of an ATM, the tray and guide rail for installing the AFD module have already been assembled. When the AFD module is placed on the sliding tray and its position is adjusted, the sliding tray will shift along the guide rail and slide towards the inside of the safe. This makes it impossible to accurately position the AFD module during installation. Therefore, the prior art requires manual assistance to fix the tray. One assembly worker is required to manually apply force to prevent the tray from sliding, while another assembly worker places the AFD module on the tray and adjusts its position to complete the installation.

[0004] The above technical solutions require at least two operators to assemble the AFD module and the sliding tray, resulting in high labor costs. Furthermore, manual assistance in fixing the sliding tray occupies installation space, affecting the installation efficiency of the AFD module and posing certain safety risks. Utility Model Content

[0005] To address the technical problem of inconvenience in manually fixing sliding trays in the prior art, this utility model provides a limiting unit and limiting fixture for limiting sliding trays, which can prevent sliding trays from sliding during the installation of AFD modules and reduce labor costs during assembly.

[0006] In a first aspect, this utility model provides a limiting unit for limiting a sliding tray to solve the above-mentioned technical problems. It includes a limiting plate and a hook connected together. The hook is used to hook onto the middle rail. The hook has an L-shaped structure and includes a connecting part and a limiting part connected together. The limiting part is vertical and is arranged opposite to the limiting plate. The limiting plate can be located between the sliding tray and the outer rail.

[0007] This invention can prevent the sliding tray from sliding under the force of the AFD module during installation by setting a limiting plate between the sliding tray and the outer rail. This improves the accuracy and convenience of AFD module position adjustment, and can be operated by one person without the need for assistance from others, greatly reducing labor costs, minimizing space occupation during assembly, and significantly improving assembly efficiency.

[0008] Furthermore, a guide rod is vertically connected to the limiting plate, the guide rod extends into the connecting part and can move axially, and a spring is provided between the limiting plate and the connecting part.

[0009] This utility model, through the guide rod and spring, can adjust the distance between the limiting plate and the limiting part, and is suitable for intermediate rails of various thicknesses, thus expanding the application range of this tooling. It also ensures that the limiting plate is clamped on the intermediate rail and will not fall off during equipment assembly.

[0010] Furthermore, the edges of the limiting plate are all provided with rounded corners.

[0011] Furthermore, the edges of the limiting portion are all provided with rounded corners.

[0012] Secondly, this utility model also provides a limiting fixture for limiting a sliding pallet, comprising two of the aforementioned limiting units for limiting a sliding pallet, wherein the two limiting units for limiting a sliding pallet are connected by a telescopic component.

[0013] This utility model, by setting two limiting units for limiting the sliding tray connected by telescopic components, can adjust the length of the tooling according to the length of the middle rail, meet the limiting requirements of various types of three-section slide rails, and improve the applicability and flexibility of the tooling.

[0014] Furthermore, the telescopic assembly includes a hollow rod one and a hollow rod two. The rod one is fitted onto the outside of the rod two. One end of the rod one and the rod two are respectively horizontally set on the end face of the corresponding limiting plate. The rod one has a plurality of pin holes along its axial direction. The rod two has a spring pin that can extend into any of the pin holes.

[0015] This invention effectively limits the length of the telescopic component through the cooperation of the pin hole and the spring pin, preventing it from retracting under external force and improving the reliability of the sliding tray position limit.

[0016] Furthermore, ball bearings are rotatably disposed on the opposing surfaces of the limiting plate and the limiting part, with the ball bearings of the limiting plate and the ball bearings of the limiting part being disposed opposite to each other, and the ball bearings protruding from the corresponding surfaces.

[0017] This invention reduces the friction between the limiting plate / limiting part and the middle rail when adjusting the length by incorporating ball bearings, thus preventing scratches on the middle rail and affecting product quality.

[0018] Furthermore, mounting holes are provided on the opposing surfaces of the limiting plate and the limiting part, a mounting seat is provided in the mounting hole, a spring is provided between the mounting seat and the bottom of the mounting hole, and the ball bearing is rotatably provided in the mounting seat.

[0019] This invention, by incorporating a second spring, can compensate for manufacturing and installation errors in components and prevent ball bearings from jamming.

[0020] Furthermore, the mounting base includes two detachably connected sub-bases, and the sub-bases are capable of rolling friction with the ball bearing.

[0021] This invention facilitates the assembly of ball bearings by using a modular mounting base.

[0022] Furthermore, two of the telescopic components are arranged in parallel.

[0023] As can be seen from the above technical solutions, this utility model has the following advantages:

[0024] This utility model provides a limiting unit and limiting fixture for limiting a sliding pallet. By setting a limiting plate between the sliding pallet and the outer rail, it can prevent the sliding pallet from sliding under the force of the AFD module during installation, improving the accuracy and convenience of AFD module position adjustment. Furthermore, it can be operated by one person without the need for assistance from others, greatly reducing labor costs, minimizing space occupation during assembly, and significantly improving assembly efficiency. The distance between the limiting plate and the limiting part can be adjusted using a guide rod and a spring, making it suitable for various thicknesses of the middle rail, expanding the application range of this fixture, and ensuring that the limiting plate is clamped onto the middle rail, preventing it from falling off during equipment assembly. Two limiting units connected by telescopic components for limiting the sliding tray are provided. The length of this tooling can be adjusted according to the length of the center rail, meeting the limiting requirements of various types of three-section slide rails and improving the applicability and flexibility of this tooling. The cooperation of pin holes and spring pins can effectively limit the length of the telescopic components, preventing retraction under external force and improving the reliability of limiting the position of the sliding tray. The ball bearings reduce the friction between the limiting plate and the limiting part and the center rail during length adjustment, preventing scratches on the center rail and affecting product quality. The second spring can compensate for manufacturing and installation errors of parts and prevent the ball bearings from jamming. The use of a modular mounting base facilitates the assembly of the ball bearings. Attached Figure Description

Detailed Implementation

[0036] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent. Specific Implementation Method 1

[0038] like Figure 1 and Figure 2 As shown, this specific embodiment provides a limiting unit for limiting a sliding tray, including a limiting plate 1 and a hook 2 connected together. The hook 2 is used to hook onto the middle rail 5. The hook 2 has an L-shaped structure and includes a connecting part 201 and a limiting part 202 connected together. The limiting part 202 is vertical and opposite to the limiting plate 1. The limiting plate 1 can be located between the sliding tray 11 and the outer rail 12. In this specific embodiment, the length L1 of the limiting plate 1 is determined according to the distance L2 between the end faces of the sliding tray 11 and the outer rail 12 after the three sections of the slide rail are fully extended. L1 is slightly smaller than L2 to ensure that it can be placed between the tray 11 and the outer rail 12. Furthermore, the distance between the corresponding end of the limiting plate 1 and the end of the outer rail 12 and the end of the tray 11 is less than 1mm to reduce the assembly error of the AFD module.

[0039] This specific embodiment sets a limiting plate 1 between the sliding tray 11 and the outer rail 12 to limit the sliding tray 11, preventing it from moving or causing a small displacement. This avoids the sliding tray 11 sliding under the force of the AFD module during installation, improving the accuracy and convenience of AFD module position adjustment. Furthermore, this tooling unit can be operated by one person without the need for assistance from others, greatly reducing labor costs, minimizing space occupation during assembly, and significantly improving assembly efficiency.

[0040] In this specific embodiment, the limiting plate 1 and the hanging part 2 are integrated bending structures. Specific Implementation Method Two

[0042] Since the three-section slide rails vary in model, size, and structure among different product types, this specific embodiment provides a limiting unit for limiting the sliding tray to broaden the applicability of the tooling unit. Figure 3 and Figure 4As shown, the structure of this specific embodiment is basically the same as that of specific embodiment one, except that: in this specific embodiment, the limiting plate 1 and the hanging part 2 are two separate structures, the hanging part 2 is a bent integrated structure, a guide rod 4 is vertically connected to the limiting plate 1 by welding, the guide rod 4 extends into the connecting part 201 and can move axially, a spring 3 is provided between the limiting plate 1 and the connecting part 201, one end of the spring 3 is connected to the end of the guide post near the limiting plate 1, and the other end of the spring 3 is connected to the connecting part 201, and the spring 3 has a tension force The function of this device also allows the limiting plate 1 and the limiting part 202 to clamp the middle rail 5, increasing the static friction between this tooling unit and the middle rail 5, making it less likely to move under external force. During installation, first pull the limiting plate 1 and the hook part 2 apart in two directions. The spring 3 is stretched and clamps the middle rail 5. Then, release the spring 3, and the limiting plate 1 and the limiting part 202 will move closer to each other and clamp on both sides of the middle rail 5. Furthermore, to facilitate the separation of the limiting plate 1 and the hook part 2 by hand, the width D1 of the limiting plate 1 is greater than the width D2 of the limiting part 202, and the width D2 of the limiting part 202 is greater than the edge thickness D3 of the middle rail 5.

[0043] To avoid scratching hands, such as Figure 6 As shown in this specific embodiment, both the edge of the limiting plate 1 and the edge of the limiting part 202 are provided with rounded corners 6.

[0044] The usage method of this tooling unit is as follows:

[0045] During installation, first pull out the sliding tray 11 to fully open the three-section slide rail. Pull the limiting plate 1 and the hook 2 in two directions. The spring 3 is stretched and locks onto the flange on the middle rail 5. Release the spring 3, and it will retract. The limiting plate 1 and the limiting part 202 will move closer to each other and lock onto the middle rail 5, so that the end of the limiting plate 1 is close to the end of the sliding tray 11. Place the AFD module on the sliding tray 11 and adjust its position as needed. At this time, the sliding tray 11 is constrained by the limiting plate 1 and will not move, which facilitates the accurate adjustment of the AFD module position. Specific Implementation Method 3

[0047] Because the extension lengths of different models of three-section slide rails vary in existing technology, various lengths of limiting units for limiting the sliding tray 11 are required to meet usage requirements. For ease of use and tooling management, such as... Figure 5 As shown, this specific embodiment provides a limiting fixture for limiting a sliding pallet, including two limiting units for limiting a sliding pallet according to the second specific embodiment, and the two limiting units for limiting a sliding pallet are connected by a telescopic component 7.

[0048] This specific embodiment sets up two limiting units for limiting the sliding tray, which are connected by telescopic components 7. The length of this tooling can be adjusted according to the length of the middle rail 5 (three-section slide rail), so as to meet the limiting requirements of various types of three-section slide rails and improve the applicability and flexibility of this tooling.

[0049] like Figure 5 As shown, in this specific embodiment, the telescopic component 7 can adopt the following specific structure: The telescopic component 7 includes a hollow rod 1 701 and a rod 2 703. The rod 1 701 is sleeved on the outside of the rod 2 703. One end of the rod 1 701 and the rod 2 703 are respectively horizontally welded to the end face of the corresponding limiting plate 1. The rod 1 701 is provided with a plurality of pin holes 704 along its axial direction. The rod 2 703 is provided with a spring pin 702. The spring pin 702 can extend into any of the pin holes 704. The distance between two adjacent pin holes 704 corresponds to the size distance between two adjacent models of three-section slide rails in the prior art, so that the position of each pin hole 704 can match the extension length of the corresponding model of three-section slide rail. After this setting, the length of the telescopic component 7 can be effectively limited, avoiding retraction under external force and improving the reliability of limiting the position of the sliding tray 11.

[0050] As a preferred option, such as Figures 6 to 9 As shown in this specific embodiment, ball bearings 8 are rotatably disposed on the opposing surfaces of the limiting plate 1 and the limiting part 202. The ball bearings 8 of the limiting plate 1 and the ball bearings 8 of the limiting part 202 are disposed opposite to each other, and the ball bearings 8 protrude from the corresponding surfaces. By setting the ball bearings 8, when adjusting the length of this tooling, the friction between the limiting part 202, the limiting plate 1 and the middle rail 5 can be changed from sliding friction to rolling friction, avoiding scratching the surface of the middle rail 5 and affecting the quality. Furthermore, to ensure the smooth rotation of the ball bearings 8, mounting holes are provided opposite to each other on the opposing surfaces of the limiting plate 1 and the limiting part 202. The mounting holes are blind holes, and mounting seats 9 are provided in the mounting holes. A second spring 10 is provided between the mounting hole and the bottom of the mounting hole. The elastic coefficient of the second spring 10 is smaller than that of the first spring 3, making it more responsive. The ball bearing 8 is rotatably disposed inside the mounting base 9. For ease of assembly, the mounting base 9 includes two detachably connected sub-bases 901. The sub-bases 901 and the ball bearing 8 can roll and rub against each other. Specifically, the sub-base 901 includes a base plate 902, one of which is connected to the second spring 10. The inner wall of the sub-base 901 is provided with an arc-shaped groove. The two sub-bases 901 are connected by bolts 903. With this arrangement, the second spring 10 can be compressed under the action of the ball bearing 8, preventing the ball bearing 8 from jamming and ensuring the rotation of the ball bearing 8.

[0051] In this specific embodiment, two sets of telescopic components 7 are arranged in parallel.

[0052] Because a telescopic component 7 is provided between the two tooling units, in order to achieve weight reduction, the length L1 of the limiting plate 1 is less than the length of the limiting plate 1 in the first specific embodiment. When the length L1 of the limiting plate 1 is less than one-quarter of L2, and the length of the telescopic component 7 is at its shortest, the length L3 of this tooling is between 10cm and 15cm, which is convenient for the operator to operate.

[0053] The usage process of this tooling is as follows:

[0054] During installation, first pull out the sliding tray 11 to fully open the three-section slide rail. At this time, the telescopic component 7 is at its shortest position. Pull the limiting plate 1 and the hook 2 in two directions with both hands. The spring 3 is stretched and locks the upper flange of the middle rail 5. Release the spring 3, and it will retract. The limiting plate 1 and the limiting part 202 will move closer to each other and lock onto the middle rail 5, so that the end of the limiting plate 1 is close to the end of the sliding tray 11. The ball bearing 8 rolls and rubs against the middle rail 5. Pull another tooling unit close to the end of the outer rail 12. The corresponding ball bearing 8 rolls and rubs against the middle rail 5 until they are close. At this time, the spring pin 702 pops out from the corresponding pin hole 704.

[0055] As can be seen from the above specific embodiments, this utility model has the following beneficial effects:

[0056] 1. By setting a limiting plate 1 between the sliding tray 11 and the outer rail 12, the sliding tray 11 can be prevented from sliding under the force of the AFD module when installing the AFD module, which improves the accuracy and convenience of AFD module position adjustment. Moreover, it can be operated by one person without the need for assistance from another person, which greatly reduces labor costs, reduces space occupation during assembly, and improves assembly efficiency.

[0057] 2. The distance between the limiting plate 1 and the limiting part 202 can be adjusted by the guide rod 4 and the spring 3. It is suitable for the middle rail 5 of various thicknesses, which expands the application range of this tooling and makes the limiting plate 1 clamped on the middle rail 5 so that it will not fall off during the equipment assembly process.

[0058] 3. By setting two limiting units for limiting the sliding tray 11 connected by the telescopic component 7, the length of this tooling can be adjusted according to the length of the middle rail 5, meeting the limiting requirements of various types of three-section slide rails, and improving the applicability and flexibility of this tooling.

[0059] 4. The cooperation between the pin hole 704 and the spring pin 702 can effectively limit the length of the telescopic component 7, prevent it from retracting under external force, and improve the reliability of limiting the position of the sliding tray 11.

[0060] 5. By setting the ball bearing 8, the friction between the limiting plate 1, the limiting part 202 and the middle rail 5 can be reduced when adjusting the length, so as to avoid scratching the middle rail 5 and affecting the product quality.

[0061] 6. By setting spring 2, manufacturing and installation errors of parts can be compensated for, and ball bearing 8 can be prevented from jamming;

[0062] 7. The assembly of the ball bearings 8 is facilitated by using the modular mounting base 9.
