Description

Technical Field

[0001] The present application belongs to the technical field of plate processing equipment, and in particular, relates to a spindle pressure plate device. Background Art

[0002] When processing plates with a cutting machine or six-sided drill, the plates often warp and deform, and cannot completely fit the plane. This is especially true for thinner plates, which are more susceptible to external factors and warp during processing. When the plate warps, the contact area and contact angle between the tool and the plate will change, thus affecting the depth of the processed hole. In order to ensure consistent depth during plate processing, an auxiliary pressure device is usually required to fix the workpiece. Flat auxiliary pressure plates are widely used for their stability and large contact area. However, when there is dust or particles on the plate, the dust or particles will form an obstacle between the plate and the pressing plate when the pressing plate is pressed down, resulting in a failure to press tightly or indentations on the surface of the plate, affecting the plate processing yield rate. Therefore, the existing flat auxiliary pressing plate is improved and designed into an air-floating pressing plate. The main function of the air-floating pressing plate is to fix the plate by jetting air downward to prevent the movement of the plate during processing. Since it does not directly contact the table, scratches and friction are avoided. In addition, the plate can move relative to the pressing plate to facilitate processing processes such as grooves. However, since the air-floating pressing plate needs to continuously generate high-speed airflow to fix the plate, its power consumption is relatively high, which will increase the operating cost of the equipment. It can be seen that the existing technology needs to be further improved and enhanced. Utility Model Content

[0003] The utility model provides a spindle pressing plate device for solving the problem of high power consumption and increased operation cost when fixing the plate only by introducing continuous airflow into the air floating pressing plate during the plate processing hole groove process.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A spindle pressure plate device comprises a cylinder mechanism and a spindle pressure plate perpendicular to the spindle, the cylinder mechanism is arranged on both sides of the spindle, the spindle pressure plate is connected to the piston rod of the cylinder mechanism, so that the spindle pressure plate can move vertically relative to the spindle, the spindle pressure plate is provided with a plurality of air outlet holes, and the plurality of air outlet holes are connected to an air intake pipeline, characterized in that the air intake pipeline comprises a first air intake pipeline and a second air intake pipeline, the first air intake pipeline and the second air intake pipeline are connected to the same air pressure source and are respectively provided with a first solenoid valve and a second solenoid valve, the first solenoid valve and the second solenoid valve are electrically connected to a controller, the controller is connected to a spindle control system, the spindle control system determines whether the spindle pressure plate and the plate have / have relative movement, so that the first solenoid valve is disconnected and the second solenoid valve is connected, the spindle pressure plate generates a continuous airflow to position the plate without contact or the first solenoid valve is connected and the second solenoid valve is disconnected, and the spindle pressure plate contacts and positions the plate after blowing dust on the surface of the plate.

[0006] The spindle pressing plate device of the utility model is designed with a first air intake pipeline and a second air intake pipeline, and respectively sets a first solenoid valve and a second solenoid valve, and flexibly adjusts the supply of airflow by controlling the on-off state of the two solenoid valves. The spindle control system is linked with the controller, and the spindle control system can judge whether there is relative movement between the spindle pressing plate and the plate. Specifically, when processing shapes such as grooves on the surface of the plate, relative movement between the spindle pressing plate and the plate is required. At this time, the controller disconnects the first solenoid valve and connects the second solenoid valve, and the spindle pressing plate generates continuous airflow to position the plate without contact, ensuring that the plate is stably suspended during the processing to avoid scratches and friction. When processing shapes such as holes on the surface of the plate, no relative movement is required between the spindle pressing plate and the plate. At this time, the controller connects the first solenoid valve and disconnects the second solenoid valve. After the spindle pressing plate blows dust on the surface of the plate, it can directly contact and position the plate for fixing without causing any pressure injuries. Since it is not necessary to continuously generate high-speed airflow to suspend the plate at this time, it can significantly reduce power consumption and reduce the operating cost of the equipment.

[0007] In a preferred implementation, the controller is provided with a timing module to control the first solenoid valve to open and close for a designed time to achieve dust blowing off the surface of the plate.

[0008] By introducing a timing module to control the opening time of the first solenoid valve to achieve circuit breaking after the dust on the plate surface is blown off, it is more intelligent and energy-saving.

[0009] In a preferred implementation, the first air inlet pipeline is further provided with a flow control valve to control the air flow size of the air outlet hole.

[0010] The flow control valve can be used to control the airflow required for dust blowing, so that it can meet the needs of dust blowing and avoid unnecessary waste. During the dust blowing stage, only enough airflow needs to be provided to remove dust and impurities on the surface of the plate, without the need to continuously supply a large amount of airflow.

[0011] In a preferred implementation, pressure plate sliding plates are slidably provided on both sides of the main shaft, the pressure plate sliding plates are vertically connected to the main shaft pressure plate, and the first gas pipeline and the second gas pipeline are arranged inside the pressure plate sliding plates.

[0012] The first gas pipeline and the second gas pipeline are built into the pressure plate sliding plate, which can effectively protect the pipelines from interference and damage from the external environment. During the processing, the pipelines may be invaded by pollutants such as dust and cutting fluid. The built-in design can avoid these problems and extend the service life of the pipelines. At the same time, the design of built-in pipelines makes the entire system more beautiful, reduces the clutter of external pipelines, reduces the occupation of operating space by pipelines, and improves the overall appearance of the equipment.

[0013] In a preferred implementation, the air inlet of the first air pipeline / the second air pipeline is arranged on the side of the pressure plate sliding plate, and the air outlet is arranged on the bottom surface of the pressure plate sliding plate.

[0014] In a preferred implementation, an air groove is provided in the spindle pressure plate, the air groove is connected to a plurality of air outlet holes, and the air outlet holes located at the bottom of the pressure plate sliding plate are connected to the air groove.

[0015] The gas can directly enter the interior of the pressing plate sliding plate 4 from the gas source, and then be distributed to each gas outlet hole through the gas groove. The gas introduced through one gas outlet hole can be evenly distributed to multiple gas outlet holes, thereby achieving uniform blowing on the surface of the plate.

[0016] In a preferred implementation, the pressure plate sliding plate is provided with a slide rail / sliding block, and sliding blocks / sliding rails are provided on both sides of the main shaft, and the slide rails and the sliding blocks are cooperatively connected.

[0017] In a preferred implementation, the cylinder mechanism includes two groups of cylinders and a pressure plate cylinder bracket, the pressure plate cylinder bracket is connected to the main shaft, and the two groups of cylinders are connected to the pressure plate cylinder bracket to realize independent operation of the two main shaft pressure plates.

[0018] The independent design of the two sets of cylinders allows the two spindle clamps to move and be controlled independently, and different operations can be performed in parallel, such as one clamp for fixing and the other for loosening or moving. If one cylinder fails, the other can still continue to work, thus reducing production interruptions caused by equipment failure. The independent cylinder design makes maintenance and replacement more convenient.

[0019] In a preferred implementation, the spindle pressure plate includes a pressure block mounting plate and a pressure block detachably connected to the pressure block mounting plate, and the pressure block is made of rubber.

[0020] The rubber clamp and the clamp mounting plate are connected in a detachable manner, which is convenient for installation and removal. When the clamp needs to be replaced or repaired, it can be done quickly and easily, reducing maintenance costs and time. At the same time, the rubber material has natural viscoelasticity and high damping properties, which can effectively absorb and alleviate the vibration and impact generated by mechanical equipment during operation, helping to protect the equipment and plates from damage.

Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

In the present invention, unless otherwise clearly specified and limited, a first feature being "upper" or "lower" than a second feature may be the first and second features directly contacting, or the first and second features indirectly contacting through an intermediate medium.

[0030] In the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are connected to form a whole only through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0031] In the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0032] The utility model is described below in conjunction with the accompanying drawings.

[0033] The specific plans adopted are:

[0034] like Figure 1-4 As shown, the utility model provides a spindle pressure plate device, including a cylinder mechanism 5 and a spindle pressure plate 2 perpendicular to the spindle 1, the cylinder mechanism 5 is arranged on both sides of the spindle, the spindle pressure plate 2 is connected to the piston rod of the cylinder mechanism 5, so that the spindle pressure plate 2 can move vertically relative to the spindle, the spindle pressure plate 2 is provided with a plurality of air outlet holes 22, and the plurality of air outlet holes 22 are connected to an air intake pipeline, characterized in that the air intake pipeline includes a first air intake pipeline 30 and a second air intake pipeline 31, the first air intake pipeline 30 and the second air intake pipeline 31 are connected to the same air pressure source and are respectively provided with a first solenoid valve 32 and a second solenoid valve 33, the first solenoid valve 32 and the second solenoid valve 33 are electrically connected to a controller, the controller is connected to a spindle control system, the spindle control system determines whether the spindle pressure plate 2 and the plate have / have relative movement, so that the first solenoid is disconnected and the second solenoid valve 33 is connected, the spindle pressure plate 2 generates a continuous airflow to position the plate without contact or the first solenoid valve 32 is connected and the second solenoid valve 33 is disconnected, and the spindle pressure plate 2 contacts and positions the plate after blowing dust on the surface of the plate.

[0035] The spindle pressure plate device of the utility model is designed with a first air intake pipeline 30 and a second air intake pipeline 31, which are respectively connected to the same air pressure source, and a first solenoid valve 32 and a second solenoid valve 33 are respectively provided. By controlling the on-off state of the two solenoid valves, the supply of air flow can be flexibly adjusted. The spindle control system is linked with the controller. The controller is not shown in the figure. Common solenoid valve controller brands such as Siemens, ABB, Schneider, Omron, etc. can be selected. Personnel in the field can understand that the spindle control system can determine whether there is relative movement between the spindle pressure plate 2 and the plate. Specifically, For example, when processing shapes such as grooves on the surface of the plate, relative movement between the spindle plate 2 and the plate is required. At this time, the controller disconnects the first solenoid valve 32 and connects the second solenoid valve 33. The spindle plate 2 generates continuous airflow to position the plate without contact, ensuring that the plate is stably suspended during processing to avoid scratches and friction. When processing shapes such as holes on the surface of the plate, relative movement between the spindle plate 2 and the plate is not required. At this time, the controller connects the first solenoid valve 32 and disconnects the second solenoid valve 33. After the spindle plate 2 blows dust off the surface of the plate, it can directly contact and position the plate to fix it. Since there is no need to continuously generate high-speed airflow to suspend the plate at this time, power consumption can be significantly reduced, reducing the operating cost of the equipment.

[0036] Furthermore, in this embodiment, the controller is provided with a timing module, and the timing module is introduced to control the opening time of the first solenoid valve 32 to realize the circuit breaking after the dust is blown off the surface of the plate, which is more intelligent and energy-saving. The timing module can accurately control the opening time of the first solenoid valve 32 to ensure that the air source can be disconnected in time after the dust is blown off, and unnecessary long-term air supply can be avoided, thereby reducing power consumption. Specifically, when processing shapes such as holes on the surface of the plate, there is no need for relative movement between the spindle plate 2 and the plate. At this time, the controller first turns on the first solenoid valve 32, and the spindle plate 2 blows dust on the surface of the plate. After the dust blowing process lasts for a period of time (for example, 1-3 seconds), the timing module is triggered to disconnect the first solenoid valve 32 and cut off the air source. Subsequently, the platen directly contacts the plate to fix it, and then performs subsequent processing operations.

[0037] In addition, a flow control valve is further provided in the first air inlet pipeline 30 to control the air flow of the air outlet hole 22. In the air-floating pressure plate system, the flow control valve can be used to control the air flow required for dust blowing, so that it can meet the dust blowing needs and avoid unnecessary waste. In the dust blowing stage, only sufficient air flow needs to be provided to remove dust and impurities on the surface of the plate, and there is no need to continuously supply a large amount of air flow. This can significantly reduce the power consumption of the air-floating pressure plate system and reduce operating costs.

[0038] See also Figure 2A pressure plate sliding plate 4 is slidingly provided on both sides of the main shaft, and the first gas pipeline and the second gas pipeline are built into the pressure plate sliding plate 4. The air inlet of the first gas pipeline / the second gas pipeline is arranged on the side of the pressure plate sliding plate 4, and the air outlet is arranged on the bottom surface of the pressure plate sliding plate 4, which can effectively protect the pipeline from interference and damage from the external environment. During the processing, the pipeline may be invaded by pollutants such as dust and cutting fluid. The built-in design can avoid these problems and extend the service life of the pipeline. At the same time, the design of the built-in pipeline makes the whole system more beautiful, reduces the clutter of the external pipeline, reduces the occupation of the operating space by the pipeline, and improves the overall appearance of the equipment.

[0039] See also Figure 3 An air groove 23 is provided in the spindle pressing plate 2, and the air groove 23 is connected to multiple air outlet holes 22. The air outlet hole located at the bottom of the pressing plate sliding plate 4 is connected to the air groove 23. The air outlet hole is located at the bottom of the pressing plate sliding plate 4 and is connected to the air groove 23, so that the gas can directly enter the inside of the pressing plate sliding plate 4 from the air source, and then be distributed to each air outlet hole 22 through the air groove 23. The gas introduced through one air outlet hole can be evenly distributed to multiple air outlet holes 22, thereby achieving uniform blowing on the surface of the plate.

[0041] In addition, the cylinder mechanism 5 includes two groups of cylinders 50 and a platen cylinder bracket 51. The platen cylinder bracket 51 is connected to the main shaft. The two groups of cylinders are connected to the platen cylinder bracket 51 to realize the independent operation of the two main shaft platens 2. The independent design of the two groups of cylinders allows the two main shaft platens 2 to be independently moved and controlled, and different operations can be performed in parallel, such as one platen is fixed and the other platen is loosened or moved. If one cylinder fails, the other cylinder can still continue to work, thereby reducing production interruptions caused by equipment failure. The independent cylinder design makes maintenance and replacement more convenient. If a cylinder has a problem, it only needs to be repaired or replaced separately, without the need for large-scale disassembly and repair of the entire mechanism. When the side edge of the platen is pressed, only one cylinder can be controlled to work, reducing power consumption.

When the pressure block 21 needs to be replaced or repaired, it can be completed quickly and easily, reducing maintenance costs and time. At the same time, the rubber material has natural viscoelasticity and high damping properties, which can effectively absorb and alleviate the vibration and impact generated by mechanical equipment during operation, and help protect the equipment and plate from damage.
