Description

technical field [0001] The invention belongs to the technical field of stainless steel circular plate processing equipment, in particular to passive self-centering heavy stainless steel circular plate drilling and clamping equipment. Background technique [0002] At present, before punching a large and heavy circular stainless steel plate, in order to ensure the accuracy of punching, the circular stainless steel plate needs to be centered. The relative displacement affects the accuracy of punching, and the circular stainless steel plate needs to be fixed on the workbench. In the prior art, in order to realize the centering operation, the workers mostly adjust the position of the stainless steel plate by manually pushing and pulling the stainless steel plate. , After the adjustment is completed, the worker clamps and fixes the circular stainless steel plate by manually adjusting the clamping mechanism. In this way, the worker needs to adjust it repeatedly. Because the circula...

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a passive self-centering equipment for drilling and clamping thick and heavy stainless steel circular plates. For thick and heavy circular stainless steel plates, workers need to manually perform centering operations before drilling and the technical problems of time-consuming, labor-intensive and poor accuracy caused by the clamping operation. Without any sensors and driving sources, this solution skillfully utilizes the gravity of the thick and heavy circular stainless steel plate itself, and is placed on the circular stainless steel plate. After receiving the upper surface of the plate, the gravity of the circular stainless steel plate itself is automatically converted into the power source for the centering operation and clamping operation through the passive self-fixing clamping mechanism, and the automatic alignment is realized only through a simple mechanical structure. The technical effect of the centering operation and clamping operation of the circular stainless steel plate does not require workers to manually perform the centering operation and clamping operation on the heavy stainless steel plate, which not only saves time and effort, but also ensures the accuracy of the centering operation

[0005] Aiming at the contradictory problem of neither too much cutting fluid (watering too much cutting fluid can ensure the cooling effect, but it will cause waste) nor too little (when the cutting fluid is too little, it needs to stop frequently to apply cutting fluid, which is time-consuming, laborious and inefficient). , this solution creatively introduces the Venturi effect. When the gas flows through the pipe whose diameter changes from thick to thin, the flow velocity of the gas increases and the pressure decreases, thereby forming a vacuum zone at the end of the ejection cavity close to the acceleration cavity, and at the end of the vacuum zone Under the action of negative pressure suction, the cutting fluid is sucked into the injection chamber. At this time, driven by the high-speed flowing compressed air, the cutting fluid is sprayed to the designated area that needs to be cooled. When the drilling speed is faster, the drill bit and The greater the calorific value of the contact position of the stainless steel circular plate, the more cutting fluid is sprayed. When the drilling speed is slower, the calorific value of the contact position between the drill bit and the stainless steel circular plate is smaller, and the less cutting fluid is sprayed. This scheme uses centrifugal The combined use of the open and close cutting fluid control drilling assembly and the cutting fluid injection assembly cleverly introduces the effect of centrifugal force. Only through a simple mechanical structure and without any sensors and detection elements, this scheme can be used when drilling It can automatically spray an appropriate amount of cutting fluid according to the calorific value without spraying excess cutting fluid, which ensures a good cooling effect and avoids the waste of cutting fluid
