Description

Technical Field

[0001] This utility model relates to the technical field of metal parts storage equipment, and in particular to a storage rack for metal parts. Background Technology

[0002] Metal parts (such as bushings, gears, bearings, precision valve cores, etc.) are widely used in precision machinery, automobiles, aerospace, and medical devices. They have a wide range of sizes and high precision requirements. Stainless steel and alloy steel are easily scratched and deformed by collisions when there is no protection. In actual production, parts need to go through temporary storage, storage before assembly, and turnover storage from processing to assembly. All of these require special storage racks to achieve classification and positioning, as well as to ensure the quality of parts and the efficiency of circulation and use.

[0003] However, existing metal parts storage still largely relies on traditional fixed-shelf storage racks, and the core problems have not been effectively solved: on the one hand, the efficiency of parts retrieval and placement is low and they are easily damaged. The shelf height of traditional storage racks is fixed and cannot adapt to the storage needs of parts of different heights. Especially for large-sized heavy parts weighing 5-20kg, due to the lack of lifting and adjustment functions, operators need to climb the racks or use forklifts to assist in retrieval and placement. Not only is it time-consuming to retrieve and place each time, but collisions are also prone to occur during handling and placement, resulting in damage to the precision of parts, such as scratches on gear meshing surfaces and deformation of shaft parts. As a result, the scrap rate of parts remains high, significantly increasing production costs.

[0004] Therefore, a storage rack for metal fittings is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a storage rack for metal parts, which can solve the core problems of existing metal parts storage that still rely heavily on traditional fixed-shelf storage racks: on the one hand, the efficiency of parts retrieval and placement is low and they are easily damaged. The shelf height of traditional storage racks is fixed and cannot adapt to the storage needs of parts of different heights. Especially for large-sized heavy parts weighing 5-20kg, due to the lack of lifting and adjustment functions, operators need to climb the racks or use forklifts to assist in retrieval and placement. Not only is it time-consuming to retrieve and place each time, but collisions are also prone to occur during handling and placement, resulting in damage to the precision of the parts, such as scratches on the meshing surfaces of gears and deformation of shaft parts. As a result, the scrap rate of parts remains high, significantly increasing production costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a storage rack for metal parts, including a base, wherein a lifting shelf mechanism is provided on the top of the base;

[0007] The lifting shelf mechanism includes support frames welded to both sides of the top of the base. Four sets of auxiliary sliding locking structures are evenly spaced from top to bottom on the front and rear sides of the inner side of the support frames. A bearing shelf is provided inside the auxiliary sliding locking structure. Four support plates are evenly spaced from top to bottom on the right side of the support frames, and the length of the four support plates increases sequentially from top to bottom. A servo motor is bolted to the top of the support plate. A lifting plate is welded to the right side of the bearing shelf. An internal thread block is embedded in the top of the lifting plate. A lead screw is fixedly connected to the output end of the servo motor. The bottom of the lead screw is threaded into the inside of the internal thread block. The bottom of the lead screw is rotatably connected to the top of the base.

[0008] Preferably, the auxiliary sliding locking structure includes a T-shaped groove, which is respectively opened on the front and rear sides of the inner side of the support frame. Slider blocks are evenly spaced from top to bottom inside the T-shaped groove, and the inner side of the slider is welded to the outer side of the bearing plate.

[0009] Preferably, the outer side of the T-shaped groove is provided with a number of locking holes evenly spaced from top to bottom, and the outer side of the slider is provided with a receiving groove.

[0010] Preferably, an electromagnetic lock is embedded inside the receiving groove, the bolt of the electromagnetic lock is located inside the corresponding lock hole, and the bolt of the electromagnetic lock is completely aligned with the axis of the lock hole.

[0011] Preferably, each of the four corners of the base is bolted with a caster wheel, and the caster wheel has a self-locking function.

[0012] Preferably, the base has counterweight grooves on both the front and rear sides of the top, and counterweight blocks are provided inside the counterweight grooves.

[0016] Preferably, the top of the bearing plate is provided with a plurality of positioning grooves, which are circular grooves, square grooves and irregular grooves.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets up a base and a lifting shelf mechanism. The auxiliary sliding locking structure on both sides of the support frame provides stable lifting guidance for the load-bearing shelf. The servo motors on the support plates at different positions drive the lead screws to rotate, which in turn drives the lifting plate and the internal thread block to achieve automatic lifting and adjustment of the load-bearing shelf. The design of the support plate length increasing from top to bottom is adapted to the installation of servo motors and lead screws of each layer, avoiding component interference. When each load-bearing shelf is lifted to a suitable position (it can be lowered to the bottom of the inner side of the support frame), it is locked by the auxiliary sliding locking structure to ensure that the load-bearing shelf is reliably fixed after stopping. Then it is easy to pick up and put down metal parts. This structure solves the problem that traditional fixed shelves cannot adapt to parts of different heights. No climbing or forklift assistance is required, which greatly shortens the time for picking up and putting down large and heavy parts, reduces the precision damage caused by handling collisions, and reduces the scrap rate.

[0019] 2. By setting up a load-bearing shelf, this application can meet the needs of classifying and placing metal parts of different specifications, so as to meet the needs of temporary storage, storage before assembly and turnover of parts, which not only ensures the quality of high-precision parts, but also improves the turnover efficiency.

[0027] 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.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A storage rack for metal fittings includes a base 1, and a lifting shelf mechanism 2 is provided on the top of the base 1.

[0030] The lifting shelf mechanism 2 includes a support frame 201 welded to both sides of the top of the base 1. Four sets of auxiliary sliding locking structures 202 are evenly spaced from top to bottom on the front and rear sides of the inner side of the support frame 201. A bearing shelf 203 is provided inside the auxiliary sliding locking structure 202. Four support plates 204 are evenly spaced from top to bottom on the right side of the support frame 201, and the length of the four support plates 204 increases sequentially from top to bottom. A servo motor 205 is bolted to the top of the support plate 204. A lifting plate 206 is welded to the right side of the bearing shelf 203. An internal thread block 207 is embedded in the top of the lifting plate 206. A lead screw 208 is fixedly connected to the output end of the servo motor 205. The bottom of the lead screw 208 is threadedly connected to the inside of the internal thread block 207. The bottom of the lead screw 208 is rotatably connected to the top of the base 1.

[0031] In this embodiment: By setting the base 1 and the lifting shelf mechanism 2, when it is necessary to adjust the height of the bearing shelf 203, the servo motor 205 on the support plate 204 is activated. The output end of the servo motor 205 drives the lead screw 208 to rotate. Since the bottom of the lead screw 208 is rotatably connected to the base 1 and the middle part is threadedly engaged with the internal thread block 207 embedded in the lifting plate 206, the rotation of the lead screw 208 will be converted into the vertical movement of the lifting plate 206, thereby driving the bearing shelf 203 to rise and fall synchronously. At this time, the auxiliary sliding locking structure 202 is in the unlocked position, which plays a role in ensuring that the four sets of auxiliary sliding locking structures 202 on the front and rear sides of the inner side of the support frame 201 are in the bearing position during the lifting process. The carrier plate 203 provides guidance to ensure smooth movement along the preset trajectory and avoid deviation. At the same time, the design of the support plate 204 with increasing length from top to bottom allows the servo motors 205 and lead screws 208 of each layer to be staggered in vertical space, preventing interference between components during operation. When the carrier plate 203 reaches the target height, its position is fixed by the auxiliary sliding locking structure 202, completing the height adjustment and positioning. This avoids the problem of not being able to adapt to accessories of different heights. In addition, when placing metal accessories, there is no need to climb or use a forklift, which greatly shortens the time for picking up and placing large and heavy accessories, reduces the precision damage caused by handling collisions, and lowers the scrap rate.

[0032] Specifically, such as Figure 4 As shown, the auxiliary sliding locking structure 202 includes a T-shaped groove 2021. The T-shaped groove 2021 is respectively opened on the front and rear sides of the inner side of the support frame 201. The slider 2022 is evenly spaced from top to bottom inside the T-shaped groove 2021. The inner side of the slider 2022 is welded to the outer side of the bearing plate 203.

[0033] Specifically, such as Figure 4 As shown, the outer side of the T-slot 2021 is provided with several locking holes 2023 evenly spaced from top to bottom, and the outer side of the slider 2022 is provided with a receiving groove 2024.

[0034] Specifically, such as Figure 4 As shown, an electromagnetic lock 2025 is embedded inside the receiving groove 2024. The latch of the electromagnetic lock 2025 is located inside the corresponding lock hole 2023, and the latch of the electromagnetic lock 2025 is completely aligned with the axis of the lock hole 2023.

[0035] In this embodiment: by setting an auxiliary sliding locking structure 202, when the load-bearing shelf 203 is raised and lowered, the slider 2022 welded on its outer side slides along the T-slot 2021 on the inner side of the support frame 201. The T-slot 2021 provides stable guidance for the slider 2022, preventing the load-bearing shelf 203 from shifting during raising and lowering. When the load-bearing shelf 203 reaches the target height, the electromagnetic lock 2025 in the slider 2022 receiving groove 2024 is activated, the locking tongue extends and precisely engages with the corresponding lock hole 2023 on the outer side of the T-slot 2021 (the locking tongue and the axis of the lock hole 2023 are completely aligned), thereby locking the position of the load-bearing shelf 203 and preventing it from sliding accidentally. This ensures both the smoothness of raising and lowering and the stability of the position when the accessories are stored.

[0036] Specifically, such as Figure 5 As shown, casters 3 are bolted to the four corners of the bottom of the base 1, and the casters 3 have a self-locking function.

[0037] Specifically, such as Figure 5 As shown, counterweight grooves 4 are provided on the front and rear sides of the top two sides of the base 1, and counterweight blocks 5 are provided inside the counterweight grooves 4.

[0038] In this embodiment: by setting up casters 3, counterweight grooves 4 and counterweight blocks 5, when the device needs to be moved, the casters 3 with self-locking function at the bottom of the base 1 can be used to easily push the device to the target position. After pushing it into place, the casters 3 are locked to prevent the device from moving accidentally. At the same time, the counterweight blocks 5 in the counterweight grooves 4 at the top of the base 1 can lower the overall center of gravity of the storage rack. Especially when carrying heavy accessories, it can reduce the risk of the storage rack tipping over, taking into account both the ease of movement and the stability of placement.

[0039] Specifically, such as Figure 5As shown, a rotating handle 6 is provided on the top of the counterweight 5, and the rotating handle 6 is made of metal.

[0040] Specifically, such as Figure 1 As shown, a protective shell 7 is bolted to the right side of the top of the base 1. The protective shell 7 is located outside the support plate 204, the servo motor 205 and the lead screw 208.

[0041] In this embodiment: by setting a rotating handle 6 and a protective shell 7, when it is necessary to pick up or put down the counterweight 5, the counterweight 5 can be easily taken out or put into the counterweight slot 4 by holding the metal rotating handle 6, avoiding slippage when carrying the counterweight 5 by hand. The protective shell 7 on the top right side of the base 1 covers the outside of the support plate 204, servo motor 205 and lead screw 208, which can prevent dust and debris from entering the drive components, and at the same time prevent the operator from accidentally touching the running servo motor 205 or lead screw 208, thus taking into account both the convenience of operation and the safety of use.

[0042] Specifically, such as Figure 1 As shown, a controller 8 is provided on the front side of the protective shell 7. The controller 8 is electrically connected to the electromagnetic lock 2025 and the servo motor 205 respectively.

[0043] Specifically, such as Figure 3 As shown, the top of the bearing plate 203 is provided with several positioning grooves 9, which are circular grooves, square grooves and irregular grooves.

[0044] In this embodiment: By setting up a controller 8 and a positioning slot 9, the operator can send commands to the electromagnetic lock 2025 and the servo motor 205 through the controller 8. If it is necessary to adjust the height of the support shelf 203, the controller 8 controls the start and stop of the servo motor 205 and the unlocking / locking of the electromagnetic lock 2025. There is no need to manually operate the drive components. When storing accessories, the positioning slots 9 (circular slots, square slots and irregular slots) on the top of the support shelf 203 can be adapted to shafts, plates and irregular metal accessories respectively, so as to realize the classified and positioned storage of accessories, avoid the stacking and squeezing of accessories, improve the operation efficiency and ensure the storage quality of accessories.

[0045] Working principle: During the use of the metal parts storage rack, the device position is first determined according to the storage requirements: using the four self-locking casters 3 at the bottom corners of the base 1, the device is pushed to the target area and the casters 3 are locked to prevent accidental movement during use. At the same time, the metal rotating handles 6 in the counterweight slots 4 on both sides of the top of the base 1 facilitate the removal and placement of the counterweights 5. The counterweights 5 lower the overall center of gravity of the device (especially when carrying large-sized heavy parts weighing 5-20kg), reducing the risk of tipping over and balancing ease of movement and placement stability. Next, the height of the support shelf 203 is adjusted before the parts are stored: the operator sends a command through the controller 8 on the front of the protective shell 7, and the controller 8 synchronously controls the servo motor 205 on the support plate 204 to start (the protective shell 7 covers the support plate 204). 04. The outer side of the servo motor 205 and the ball screw 208 can block dust and prevent accidental contact. The output end of the servo motor 205 drives the ball screw 208 (model SFU2005, diameter 20mm, lead 5mm, positioning accuracy ≤0.05mm, repeatability ≤0.02mm) to rotate. Because the bottom of the ball screw 208 is rotatably connected to the base 1 and the middle part is threadedly engaged with the internal thread block 207 embedded in the lifting plate 206 on the right side of the bearing plate 203, and the high-precision lead design of the ball screw 208 can control the lifting height error of the bearing plate 203 within ±0.5mm, the rotation of the ball screw 208 can be smoothly converted into the vertical movement of the lifting plate 206, thereby driving the bearing plate 203 to rise and fall synchronously. During the lifting process, the support frame 201 The sliders 2022 (welded to the outer side of the bearing plate 203) within the inner front and rear T-slots 2021 slide along the slots, providing stable guidance for the bearing plate 203 and preventing deviation. Simultaneously, the design of the support plate 204, with its length increasing from top to bottom, allows the servo motors 205 and lead screws 208 of each layer to be staggered in vertical space, preventing component interference. When the bearing plate 203 reaches the target height, the controller 8 sends a locking command to the electromagnetic lock 2025 within the slider 2022 receiving slot 2024. At this time, the lead screw 208 achieves instant braking (braking response time ≤ 10ms) through pulse control of the servo motor 205, stably stopping the bearing plate 203 at the target height (error ≤ 0.5mm). The electromagnetic lock 2025's locking tongue (6mm in diameter) engages with the T-slot. The outer locking hole 2023 (8mm diameter) of the groove 2021 is fully aligned with the axis, and the locking tongue is inserted into the locking hole 2023 without deviation to avoid misalignment and jamming, ensuring reliable fixation of the shelf. Finally, the accessories are stored: shafts, plates, and irregular metal accessories are placed into the corresponding circular, square, and irregular grooves on the top of the load-bearing shelf 203, respectively. By classifying and positioning, the accessories are prevented from being stacked, squeezed, or deformed. When picking up or turning over the parts, the above height adjustment steps are repeated. The controller 8 is conveniently operated without climbing or forklift assistance. The repeatability of the lead screw 208 (≤0.02mm) ensures that the load-bearing shelf 203 will still accurately return to the preset height after multiple adjustments. This not only shortens the time for picking up and putting down large-sized accessories, but also reduces the precision damage caused by handling collisions, effectively reducing the scrap rate.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
