[0002] Currently, the standard worktable on machine tools is a general-purpose T-slot platform. When clamping workpieces, various fixtures are required to position the workpiece on the worktable. In addition, the workpiece position needs to be manually measured and communicated to the machine tool, a process commonly known as workpiece alignment. For some special products, such as thin sheet metal workpieces, clamping methods are not allowed to fix the workpiece, and separate vacuum gripping equipment is required.

[0003] Vacuum gripping and quick-positioning clamping fixtures already exist on the market, but they are used separately, and their main drawback is:

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example

[0030] like Figure 1-6 As shown, the vacuum quick-lock function table includes a mounting plate 1, a number of assembly bolts 2 and a cavity plate 3. The number of assembly bolts 2 are embedded in the lower wall of the mounting plate 1. The cavity plate 3 is located at the upper end of the mounting plate 1 and is fitted onto the number of assembly bolts 2. A pneumatic fixing structure is installed at the upper end of the cavity plate 3.

[0031] The pneumatic fixing structure includes: an air inlet chamber, a positioning plate 5, an adsorption chamber, several mounting holes 7, several quick-lock components, an air inlet connector 8, an adsorption connector 9, a pressure gauge 10, an adsorption switch 11, several fixing holes 12, and several adsorption air passages 13.

[0032] The air intake chamber is located between the mounting plate 1 and the cavity plate 3. The positioning plate 5 is installed on the upper end of the cavity plate 3 and is fitted onto the upper ends of several assembly bolts 2. The adsorption chamber is located between the positioning plate 5 and the cavity plate 3. Several mounting holes 7 are all opened on the upper wall surface of the cavity plate 3. The bottom ends of several quick-lock components are all installed in several mounting holes 7, and their upper ends are all connected to the lower end of the positioning plate 5. The air intake connector 8 is embedded in the front wall surface of the cavity plate 3 and is connected to the air intake... The cavity is connected, the adsorption connector 9 is embedded in the front wall of the cavity plate 3 and is connected to the adsorption cavity, the pressure gauge 10 is embedded in the front wall of the cavity plate 3 and is connected to the adsorption cavity, the adsorption switch 11 is embedded in the front wall of the cavity plate 3 and is connected to the adsorption cavity, a plurality of fixing holes 12 are opened on the upper wall of the positioning plate 5 and correspond to the quick lock assembly, and a plurality of adsorption air passages 13 are opened on the lower wall of the positioning plate 5 and are connected to the adsorption connector 9.

[0033] It should be noted that during use, the operator first places the device in the designated position and then assembles the mounting plate 1, cavity plate 3, and positioning plate 5 using several assembly bolts 2. This creates an air intake chamber and an adsorption chamber between the mounting plate 1, cavity plate 3, and positioning plate 5. When positioning the workpiece, the pull stud is connected to the workpiece or fixture. The conical surface of the pull stud engages with several fixing holes 12 on the upper end of the positioning plate 5 to achieve precise positioning. Gas is then injected into the air intake chamber through the air intake connector 8, which activates the quick-lock assembly, tightening the bottom end of the pull stud to achieve rapid positioning and clamping of the workpiece. When adsorption and fixation of the workpiece are required, the workpiece is placed on the upper end of the positioning plate 5, the adsorption connector 9 is connected to the designated adsorption equipment, and the adsorption switch 11 is turned on. The adsorption equipment then... The gas in the adsorption chamber is extracted and the workpiece is quickly adsorbed and fixed through several adsorption air channels 13 connected to the adsorption chamber. Several vacuum components are specially arranged in an array in the several adsorption air channels 13 at the upper end of the positioning plate 5. The vacuum components can intelligently determine whether there is an object blocking the components to determine whether the adsorption air channel 13 is open. If there is an object blocking the adsorption air channel 13, the adsorption air channel 13 is open to ensure the adsorption function of the object. If there is no object blocking the adsorption air channel 13, the adsorption air channel 13 is closed to ensure the stability of the vacuum adsorption function. The positioning and locking functions of any workpiece or tooling can be realized through multiple positioning and locking mechanisms arranged in a matrix. By combining the vacuum holding function with the function table, various workpiece positioning and locking functions can be realized. For special workpieces, positioning and locking and vacuum holding can be used at the same time, making the processing more stable and eliminating the need to change fixtures to adapt to different products.

[0034] In a specific implementation, one of the quick-lock components includes: mounting block 14, six springs 15, support body 16, conversion disc 17, rotating shaft 18, three locking blocks 19, and three positioning slides 20;

[0035] The mounting block 14 is installed in one of the mounting holes 7. All six springs 15 are installed on the upper end of the mounting block 14. The support body 16 is installed on the upper end of the springs 15. The conversion disc 17 is installed on the upper wall of the support body 16. The upper end of the rotating shaft 18 is installed on the lower wall of the positioning plate 5 through a bearing, and the bottom end is movably embedded in the conversion disc 17. One end of each of the three locking blocks 19 is installed on the upper wall of the rotating shaft 18 through a mounting shaft. All three positioning grooves 20 are opened on the lower wall of the positioning plate 5 and correspond to the other end of each of the three locking blocks 19.

[0036] It should be noted that when the workpiece is quickly locked, pressurized gas is delivered to the air intake chamber through the air intake connector 8. The gas pushes the support body 16 and the conversion plate 17 to move upward. The three actuating rods 6 at the upper end of the conversion plate 17 cooperate with the three actuating grooves 4 at the upper end of the rotating shaft 18, causing the rotating shaft 18 to rotate in the bearing. This causes the three locking blocks 19 to unfold under the action of the three positioning slides 20. The operator inserts the positioning pin of the workpiece between the three locking blocks 19. Then, the gas in the air intake chamber is discharged, causing the support body 16 and the conversion plate 17 to move downward under the action of the six springs 15. This causes the rotating shaft to rotate in the opposite direction, causing the three locking blocks 19 to close under the action of the three positioning slides 20. This clamps and fixes the positioning pin between the three locking blocks 19, achieving the purpose of quick locking of the workpiece.

[0037] The vacuum quick-locking functional table is composed of multiple components, mainly divided into three parts: a positioning plate 5 and its components, and a cavity plate 3 and its components. It integrates vacuum holding, pneumatic locking, and precise positioning functions into a multi-functional worktable. The positioning and locking function connects the pull stud to the workpiece or fixture, achieving precise positioning through the conical surface of the pull stud and the conical surface of the functional table. The locking mechanism then tightens the pull stud. The vacuum holding function utilizes a special array of 378 vacuum components that intelligently determine whether an object is obstructing the vacuum holes. If an object obstructs the holes, the vacuum holes open to ensure the suction function; otherwise, they close to ensure stable vacuum suction. Multiple positioning and locking mechanisms arranged in a matrix can achieve positioning and locking of any workpiece or tooling. By combining the vacuum holding function with the functional table, it can achieve various workpiece positioning and locking functions. For special workpieces, positioning, locking, and vacuum holding can be used simultaneously, making processing more stable and eliminating the need to change fixtures to adapt to different products.

[0038] a) When the workpiece requires precise positioning and quick locking, connect the air source to the air inlet. At this time, the quick locking mechanism will be opened through the air passage inside the worktable.

[0039] b) Fix the rivet in the designated position on the workpiece, and then insert the rivet into the conical positioning hole 23;

[0040] c) Remove the air source, tighten the rivet by locking the locking mechanism, and position it by positioning it with the worktable and the conical positioning hole 23 to fix and position the workpiece;

[0041] d) When the workpiece requires vacuum holding function, insert the vacuum air source into the vacuum chamber pump connector to form a vacuum negative pressure in the vacuum chamber inside the function table;

[0042] e) Place the workpiece to be processed on the worktable surface and determine its position;

[0043] f) Turn on the vacuum switch and observe the negative pressure gauge to stabilize. The function table will automatically determine the position of the workpiece and fix it on the worktable surface by the suction force of the vacuum hole under the workpiece.

[0044] g) When special workpieces require the simultaneous use of precise positioning, quick locking, and vacuum holding functions, they can be used at the same time;

[0045] h) The positioning and locking function can also be switched by changing the pull pin.

[0046] In the specific implementation process, the number of mounting holes 7 corresponds to the number of fixing holes 12.

[0047] In the specific implementation process, a protective pull stud 21 is movably embedded in the fixing hole 12.
