Description

Technical Field

[0001] This utility model belongs to the field of machining fixture technology, and in particular relates to a vacuum chuck for processing titanium plates. Background Technology

[0002] Titanium plates, as an important industrial material, are widely used in high-precision manufacturing fields such as aerospace, medical devices, and chemical equipment due to their high strength, light weight, and excellent corrosion resistance. In the CNC machining, milling, and cutting processes of titanium plates, they must be stably and securely fixed to the worktable using fixtures. Vacuum chuck fixtures have become the mainstream clamping method in titanium plate processing because they provide full-range contact, uniform clamping force, and do not cause mechanical scratches or deformation to the surface of the titanium plate.

[0003] Existing vacuum chucks for titanium plate processing still have some problems during use. For example, during the processing of titanium plates, small metal chips or cutting fluid residues are generated. If these impurities fall into the intended adsorption area of ​​the chuck, the chuck's sealing strip cannot fully adhere to the surface of the titanium plate, causing local air leakage. This leads to insufficient vacuum, reduced adsorption force, and even workpiece displacement, seriously affecting processing accuracy and safety. Secondly, traditional vacuum chucks are usually designed with a single, continuous sealed cavity. This design has extremely stringent requirements for the flatness of the workpiece surface. Since the titanium plate itself may have slight warping or local depressions generated during processing, the vacuum in a single sealed cavity will be quickly lost due to leakage at any point, causing the vacuum of the entire chuck and even the entire adsorption system to fail, making reliable adsorption impossible. This forces additional time and cost to pre-level the plate during production, significantly reducing production efficiency.

[0004] To address these issues, we provide a vacuum chuck for processing titanium plates. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum suction cup for titanium plate processing. By combining a partitioned adsorption mechanism and a cleaning mechanism, it solves the problem in the existing vacuum suction cups where impurities falling into the predetermined adsorption area of ​​the suction cup can cause local air leakage, minor warping deformation, or local depressions during processing, leading to vacuum failure of the entire suction cup and even the entire adsorption system, thus making reliable adsorption impossible.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a vacuum suction cup for processing titanium plates, comprising a main rod, a first slider slidably connected to the surface of the main rod, a crossbar fixedly connected to the bottom of the first slider, a second slider slidably connected to the surface of the crossbar, a vacuum tube fixedly connected to one side of the second slider, a suction cup disposed at the bottom of the vacuum tube, a partitioned adsorption mechanism disposed at the bottom of the suction cup, the partitioned adsorption mechanism comprising a first sealing strip fixedly connected to the bottom of the suction cup, a second sealing strip fixedly connected to the bottom of the suction cup, and a vacuum suction component disposed at the bottom of the suction cup, a cleaning mechanism disposed on one side of the second slider, the cleaning mechanism comprising a vertical plate fixedly connected to one side of the second slider, a telescopic component disposed inside the vertical plate, and a blowing component disposed at the bottom of the telescopic component.

[0008] The present invention is further configured such that the first sealing strip is arc-shaped, three of the first sealing strips are arranged in a group at the bottom of the suction cup, and seven of the second sealing strips are arranged in a group at the bottom of the suction cup. The cross-sectional shape of the first sealing strip and the second sealing strip is semi-circular, and the first sealing strip and the second sealing strip are designed to intersect perpendicularly to form a cross grid.

[0009] The present invention is further configured such that the vacuum suction assembly includes a circular tube fixedly connected to the bottom of the suction cup, and a suction nozzle connected to the bottom of the circular tube.

[0010] The present invention is further configured such that the telescopic assembly includes a telescopic rod slidably connected inside the vertical plate, and a spring sleeved on the surface of the telescopic rod.

[0011] The present invention is further configured such that the blowing assembly includes a blowing plate disposed on one side of the suction cup and a blower nozzle connected to one side of the blowing plate.

[0012] The present invention is further configured such that two second sliders are arranged in a group on the surface of the crossbar, the number of crossbars is four, and the number of suction cups is eight.

[0013] The present invention is further provided that a rubber pad is fixedly connected to the bottom of the blowing plate, and the rubber pad is square in design.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses a partitioned adsorption mechanism where the first and second sealing strips intersect perpendicularly to form a cross grid, dividing the bottom of the suction cup into multiple independent sealed chambers. In conjunction with a vacuum suction component, each chamber is independently evacuated. When the suction cup descends to adhere to the titanium plate, each chamber simultaneously establishes negative pressure. If a leak occurs in a certain area due to unevenness of the plate or the presence of impurities, that local chamber fails, while the remaining chambers maintain a certain level of adsorption force. This achieves redundant backup of adsorption force, effectively improving the adaptability of the vacuum suction cup to titanium plates with surface defects, effectively avoiding overall adsorption failure due to single-point leakage, and ensuring the safety and stability of the processing.

[0016] 2. This utility model achieves surface self-cleaning before adsorption by linking the blowing component and the telescopic component in the cleaning mechanism. During the descent of the suction cup, the rubber pad at the bottom of the blowing plate contacts the titanium plate first, and the blowing nozzle sprays air outward to remove impurities. Then the suction cup continues to descend, and the reaction force compresses the spring to retract the telescopic rod, which drives the blowing plate to retract upward to avoid the adsorption area. This can automatically blow away debris and other impurities on the surface of the titanium plate before adsorption, eliminating the risk of sealing failure caused by impurity contamination from the source, and effectively improving the clamping success rate and processing reliability.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figures 1-5 This utility model is a vacuum suction cup for titanium plate processing, including a main rod 1, a first slider 2 slidably connected to the surface of the main rod 1, a crossbar 3 fixedly connected to the bottom of the first slider 2, a second slider 4 slidably connected to the surface of the crossbar 3, a vacuum tube 5 fixedly connected to one side of the second slider 4, a suction cup 6 provided at the bottom of the vacuum tube 5, a partitioned adsorption mechanism 7 provided at the bottom of the suction cup 6, the partitioned adsorption mechanism 7 including a first sealing strip 71 fixedly connected to the bottom of the suction cup 6, a second sealing strip 72 fixedly connected to the bottom of the suction cup 6, and a vacuum suction component 73 provided at the bottom of the suction cup 6, a cleaning mechanism 8 provided on one side of the second slider 4, the cleaning mechanism 8 including a vertical plate 81 fixedly connected to one side of the second slider 4, a telescopic component 82 provided inside the vertical plate 81, and a blowing component 83 provided at the bottom of the telescopic component 82.

[0028] Specifically, the partitioned adsorption mechanism 7 divides the adsorption surface into numerous independent sealed chambers through a cross-grid design of the first sealing strip 71 and the second sealing strip 72. The bottom of each chamber is connected to the suction nozzle 732 of the vacuum suction assembly 73. When the suction cup 6 descends to the surface of the titanium plate, each sealed chamber independently completes the vacuuming process. If a leak occurs in a certain area due to unevenness of the titanium plate surface or the presence of impurities, only the vacuum in that local chamber will fail, while all other independent chambers will still maintain strong adsorption force, thus avoiding the failure of the entire adsorption process due to a single point of leakage. When the suction cup 6 loses its adsorption function, the cleaning mechanism 8 is responsible for pre-treating the surface of the titanium plate before adsorption. It removes impurities in the adsorption area by blowing. Before the suction cup 6 descends to adsorb, the blower nozzle 832 at the bottom of the blowing assembly 83 approaches the surface of the titanium plate and blows air outward. When the suction cup 6 continues to descend and enter the adsorption process, the blowing plate 831 compresses the spring 822 under the reaction force and retracts upward to avoid the working area of ​​the suction cup 6. This process realizes automatic cleaning before adsorption, avoids the risk of leakage caused by impurities, and improves the clamping success rate.

[0029] Example 2

[0030] Please see Figures 1-5 Based on Embodiment 1, the first sealing strip 71 is arc-shaped, and three first sealing strips 71 are arranged in a group at the bottom of the suction cup 6. Seven second sealing strips 72 are arranged in a group at the bottom of the suction cup 6. Both the first and second sealing strips 71 and 72 have semi-circular cross-sections and are designed to intersect perpendicularly, forming a cross-grid. The vacuum suction assembly 73 includes a circular tube 731 fixedly connected to the bottom of the suction cup 6, and a suction nozzle 732 connected to the bottom of the circular tube 731. Five circular tubes 731 are arranged in a group at the bottom of the suction cup 6. The bottom of the suction nozzle 732 extends to the bottom of the suction cup 6. The vacuum tube 5 is connected to the circular tube 731 through a pipe. The telescopic assembly 8... 2 includes a telescopic rod 821 slidably connected inside the vertical plate 81, and a spring 822 sleeved on the surface of the telescopic rod 821. The blowing assembly 83 includes a blowing plate 831 set on one side of the suction cup 6, and a blower nozzle 832 connected to one side of the blowing plate 831. The blowing plate 831 is connected to an external fan through a pipe. The bottom of the telescopic rod 821 is fixedly connected to the top of the blowing plate 831. The second slider 4 is set in groups of two on the surface of the horizontal bar 3. There are four horizontal bars 3 and eight suction cups 6. The blowing assembly 83 is set in groups of two on one side of the horizontal bar 3. Both sets of blower nozzles 832 are designed to blow air outward. A rubber pad 9 is fixedly connected to the bottom of the blowing plate 831. The rubber pad 9 has a square design.

[0031] Specifically: The first sealing strip 71 and the second sealing strip 72 divide the bottom of the suction cup 6 into multiple sealing cavities. Combined with the vacuum suction component 73, the bottom of the suction cup 6 is divided into multiple vacuum suction cavities, preventing the suction cup 6 from failing to effectively adsorb the titanium plate due to unevenness. The vacuum suction component 73 draws air out of each vacuum suction cavity at the bottom of the suction cup 6, creating a vacuum state to complete the adsorption of the titanium plate. The telescopic component 82 retracts the telescopic rod 821 into the vertical plate 81 when the suction cup 6 adsorbs downwards, causing the blowing component to retract upwards, thus avoiding interference with the suction cup 6's adsorption of the titanium plate. The blowing component 83 blows air onto the surface of the titanium plate, preventing impurities from falling onto the surface and preventing the suction cup 6 from adsorbing the titanium plate. The outward-facing blow nozzles 832 allow impurities to be blown outwards. The rubber pad 9 prevents the bottom of the blowing plate 831 from making hard contact with the surface of the titanium plate.

[0032] The working principle of this utility model is as follows: the operator drives the equipment to move through the external control system. The main rod 1 drives the entire device to be positioned above the titanium plate. The external driving device drives the main rod 1 to move downward. At this time, the rubber pad 9 on the top of the blowing plate 831 contacts the titanium plate. The blowing nozzle 832 connected to one side of the blowing plate 831 sprays out a high-speed airflow to blow the surface of the titanium plate. The airflow blows away the debris and other impurities in the adsorption area, preparing for subsequent adsorption.

[0033] Subsequently, the suction cup 6 continues to descend, and the purge plate 831, under the reaction force of the titanium plate, presses the telescopic rod 821 upward. The telescopic rod 821 retracts into the vertical plate 81, causing the purge plate 831 to retract upward to avoid affecting the suction of the suction cup 6. The bottom of the suction cup 6 is in contact with the cleaned surface of the titanium plate. The vacuum tube 5 simultaneously evacuates multiple independent sealing cavities formed by the intersecting grid of the first sealing strip 71 and the second sealing strip 72 through the annular tube 731 and the suction nozzle 732. Each cavity independently establishes a negative pressure. Even if some cavities are not sealed well due to minor indentations in the titanium plate, the remaining cavities can still provide sufficient suction force, thereby firmly adsorbing and fixing the titanium plate, completing the clamping.

[0034] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
