Description

Technical Field

[0001] This utility model relates to the technical field of machine tool worktable locking equipment, specifically to a pneumatic release type multi-worktable quick interchange mechanism. Background Technology

[0002] In the field of CNC (Computer Numerical Control) single-machine small-batch parts processing, a dual-station manual worktable exchange method is traditionally used to improve production efficiency. This technology, through the configuration of two movable bases, each with a fixed worktable, allows the operator to pre-clamp the parts to be processed on the other worktable while the machine tool is processing. This layout effectively utilizes machine tool downtime, increasing machine uptime and operator efficiency.

[0003] In actual operation, the worktable is moved manually by means of linear bearings as the track, while the feeding uses needle roller bearings, which makes the movement process smoother and the manual operation easier.

[0004] However, in the design of traditional dual-station manual exchange worktables, an inverted locking device must be installed to fix the worktable in place due to the need for the internal locking mechanism of the in-machine part fixture set. This design prevents the worktable from being quickly and directly removed from the base, limiting the number of parts that can be pre-clamped and thus failing to meet the needs of large-scale or high-efficiency production. Utility Model Content

[0005] In view of this, the present invention provides a pneumatic release type multi-worktable quick interchange mechanism. The present invention can indirectly realize the locking or unlocking of the material tray through the telescopic component, thereby facilitating the removal of the material tray and quick replacement of the new material tray, thereby increasing the material processing efficiency or equipment maintenance efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides a pneumatic release-type multi-worktable quick-change mechanism, including a base that slides on a machine tool, a material tray fixed on the base by a locking structure, the material tray being used to place materials to be processed, the locking structure including several sets of clamping plates set at the bottom of the material tray, each set of clamping plates having two plates arranged symmetrically, a telescopic component provided on the upper surface of the base, the telescopic component including several sets of clamping blocks, each set of clamping blocks having two plates located between two clamping plates, the telescopic component can cause the two clamping blocks to move relative to each other or back to back, the two clamping blocks moving back to back can respectively abut against the two clamping plates so that the position of the material tray is fixed.

[0007] The pallet has an L-shaped structure, with the corner of the pallet located at the end furthest from the material tray. The pallet blocks can be moved into the corner of the pallet. The L-shaped structure of the pallet also prevents the material tray from moving up and down after it is fixed.

[0008] The end of the pallet away from the material tray has a conical structure with an inclined surface that faces the material tray, making it easy to insert the pallet blocks into the corner of the pallet.

[0009] The end of the card block near the card plate has a conical structure with an inclined surface. This inclined surface is located on the side of the card block away from the material tray. The two inclined surfaces work together to make it easier for the card block to be inserted into the corner of the card plate.

[0010] The telescopic assembly includes a fixed block corresponding to each locking block. The fixed block has an air chamber on its side. The locking block is slidably mounted in the air chamber. Each air chamber is connected to an air supply pipe. Multiple air supply pipes are connected to a cylinder mounted on the base. Multiple locking blocks can be simultaneously controlled to extend or retract in the air chamber by the cylinder.

[0011] Each fixed block is equipped with a guide block above it, and the corresponding guide block has a guide groove at the bottom of the material tray. The guide groove can prevent the lateral position of the material tray from deviating when it is placed.

[0012] The guide block and / or guide groove have a conical structure, which can automatically correct deviations when the material tray is placed in a wrong position.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. Enables rapid interchange of multiple workbenches, improving production efficiency: This invention enables the vertical lifting and rapid interchange of multiple worktables (material trays) by setting a retractable locking block assembly on the base and combining it with the L-shaped locking plate structure at the bottom of the material tray.

[0014] Operators can pre-load the parts to be processed onto multiple material trays and automatically lock or release them by controlling the extension and retraction of the clamps with cylinders. The time for a single table change is reduced to the second level, which significantly improves the machine uptime and material processing efficiency.

[0015] 2. Pneumatic automated control reduces labor costs: This invention employs a cylinder-driven mechanism to extend and retract the locking blocks, with multiple blocks moving synchronously under centralized control via an air supply pipe, replacing the cumbersome operation of traditional manual locking devices. The operator only needs to control the cylinder's start and stop to fix and release the worktable, achieving an automated loading and unloading process. Combined with robots or robotic arms, it can further construct unmanned processing units, reducing manual intervention and lowering labor costs.

[0016] 3. Optimized structural design to enhance system stability: L-shaped pallet and tapered guide structure: The pallet is designed in an L-shape, and the corner can accommodate the pallet block to prevent the material tray from moving up and down; both the ends of the pallet and the pallet block adopt a tapered structure and are provided with inclined surfaces to form a self-guiding function, making it easier for the pallet block to be inserted into the corner of the pallet, thus improving assembly accuracy and reliability.

[0017] Guide block and conical groove correction: The conical guide block above the fixed block cooperates with the guide groove at the bottom of the material tray to automatically correct lateral deviation when the material tray is placed, avoiding locking failure due to positional offset and further improving the stability of system operation.

[0018] 4. Highly modular and expandable, adaptable to diverse production needs: The base and material tray of this utility model adopt a standardized design, and can be flexibly adapted to the processing needs of workpieces of different sizes by adjusting the specifications of the material tray.

[0019] Meanwhile, the pneumatic control system supports independent or coordinated control of multiple card blocks, providing technical reserves for future upgrades to more complex flexible manufacturing systems (FMS), and has high industrial promotion value. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-2 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0023] This embodiment provides a pneumatic release-type multi-table quick-interchange mechanism, such as... Figure 1As shown: A base 2 is slidably mounted on the machine tool 1. A material tray 3 is fixed to the base 2 via a locking structure. The material tray 3 is used to place workpieces. The locking structure includes two sets of clamping plates 4 located at the bottom of the material tray 3. Each set of clamping plates 4 has two plates, and the two sets of clamping plates 4 are arranged in a rectangular structure at the bottom of the material tray 3, i.e., the four clamping plates 4 are located at the four corners of the bottom of the material tray 3. Each set of clamping plates 4 is symmetrically arranged. Corresponding to the two sets of clamping plates 4, a telescopic component is also provided on the upper surface of the base 2. The telescopic component is connected to two sets of clamping blocks 5, each set of clamping blocks 5 has two blocks, and each set of clamping blocks 5 is located between the corresponding set of clamping plates 4. Furthermore, the telescopic component allows each set of locking blocks 5 to move relative to each other or in opposite directions. When the telescopic component drives the two sets of locking blocks 5 to move in opposite directions synchronously, the locking blocks 5 can abut against the side wall of the clamping plate 4, thereby indirectly fixing the material tray 3. The base 2 can then slide the material tray 3 on the machine tool 1, thus enabling normal processing of workpieces. When the telescopic component controls the two sets of locking blocks 5 to move relative to each other synchronously, the fixing effect of the locking blocks 5 on the material tray 3 can be canceled, making it easier to replace or disassemble the material tray 3, thereby increasing maintenance efficiency.

[0024] Preferably, each card plate 4 is an L-shaped structure with a corner end located at the end of the card plate 4 away from the material tray 3. The corner portions on each group of card plates 4 are arranged opposite to each other, so that the card blocks 5 can move into the corner portion on the card plate 4 when they move in opposite directions. The card blocks 5 can then be located between the card plate 4 and the bottom plate of the material tray 3. Thus, after each group of card blocks 5 moves in opposite directions, not only can the material tray 3 be fixed, but the vertical vibration of the material tray 3 can also be further prevented.

[0025] Specifically, the end of the pallet 4 away from the material tray 3 is a conical structure with an inclined surface facing the material tray 3. When the pallet 5 moves toward the inner corner of the pallet 4, if the position of the material tray 3 is slightly deviated, the pallet 5 can contact the inclined surface on the pallet 5. This not only corrects the deviation of the material tray 3 but also makes it easy for the pallet 5 to be quickly inserted into the corner of the pallet 4.

[0026] Correspondingly, the end of the card block 5 near the card plate 4 is a conical structure. This conical structure forms an inclined surface, which is located on the side of the card block 5 away from the material tray 3. As the card block 5 moves toward the corner of the card plate 4, the two inclined surfaces on the card block 5 and the card plate 4 can abut against each other, making the movement of the card block 5 into the corner of the card plate 4 smoother.

[0027] Furthermore, the telescopic component includes a fixing block 6 corresponding to each locking block 5. The fixing block 6 has an air chamber on its side, and the locking block 5 is slidably mounted in the air chamber. Each air chamber is connected to an air supply pipe 7. Multiple air supply pipes 7 are connected to a cylinder 8 mounted on the base 2. When the cylinder 8 works, it supplies gas to the air chamber through the air supply pipe 7. The air pressure will push the locking block 5 to slide out of the air chamber, thereby indirectly creating a fixing effect on the material tray 3. When the cylinder 8 controls the air supply pipe 7 to draw in air, a negative pressure environment can be formed in the air chamber, thereby allowing the locking block 5 to retract into the air chamber, thus canceling the fixing effect on the material tray 3.

[0028] It is worth mentioning that each fixed block 6 is equipped with a guide block 9 above it, such as Figure 2 As shown: The guide block 9 is provided with a guide groove 10 at the bottom of the material tray 3; and the guide block 9 and the guide groove 10 are conical structures, so that if the position of the material tray 3 is slightly tilted during the downward placement of the material tray 3, the top of the guide block 9 can contact the inner wall of the guide groove 10 to automatically correct the material tray 3.

[0029] Furthermore, it should be noted that, in the description of this utility model, 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 according to the specific circumstances.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
