Description

Technical Field

[0001] The present application relates to the field of machine tools, and in particular to a chip collection device and method for a double-station CNC machine tool. Background Art

[0002] Dual-station CNC machine tools have the function of processing two workpieces at the same time, or processing workpieces through two sets of cutting tools. They are mainly used for processing complex workpieces.

[0003] In the related art, a Chinese patent with publication number CN118493084A discloses a duplex CNC machine tool, which arranges two pairs of slide rails on the machine tool base, and assembles two working parts on each pair of slide rails, including a spindle assembly and a turret structure. The spindle assembly and the turret structure are both slidably connected in the slide rails through the base. The two turret structures can process the workpieces of the two spindle assemblies respectively, or the two turret structures can cooperate to synchronously process the workpieces on any spindle assembly at the same time. It has the characteristics of high processing efficiency and strong adaptability, but there are great difficulties in collecting and cleaning the debris at the slide rails. If the debris is not completely cleaned, it will affect the stability and processing accuracy of the working parts on the slide rails, especially when the workpiece is cut with coolant. The coolant has a certain viscosity, and the debris falls to the slide rails along with the splashing coolant, thereby sticking to the guide rails, making it more difficult to clean. Therefore, there is still room for improvement. Summary of the invention

[0004] In order to improve the situation where debris is stuck to the slide rail, the present application provides a chip collection device and method for a duplex CNC machine tool.

[0005] The present application provides a dual-station CNC machine tool chip collection device and method using the following technical solutions: A chip collection device for a double-station CNC machine tool includes a plurality of foldable baffles for covering the surface of a slide rail and a collection trough arranged between two adjacent slide rails. The foldable baffles correspond to the slide rails one by one, and the two ends of the foldable baffles are respectively connected between two working parts on the corresponding slide rails. The foldable baffles can be folded or unfolded along the length direction of the slide rail. The side of the foldable baffles extends to the notch of the collection trough, and the bottom of the collection trough is connected to a drain pipe.

[0006] By adopting the above technical scheme, the two ends of the foldable baffle are respectively installed between the two working parts on the corresponding slide rail, and cover the corresponding slide rail surface at the same time, so as to shield the slide rail, reduce the coolant and debris from falling directly on the slide rail, which is beneficial to improve the situation where the debris is adhered to the slide rail, and the foldable baffle can be folded and retracted as the two working parts on the slide rail move relative to each other, which is beneficial to maintain the shielding effect on the slide rail without affecting the normal movement of the working parts of the machine tool, and the folded state of the foldable baffle forms a plurality of guide grooves, which can not only collect the coolant splashed onto the surface of the foldable baffle and guide it into the collecting groove, but also independently collect the coolant, so that the foldable baffle is balanced in force, and the collecting groove discharges the coolant and debris out of the machine tool through the drain pipe, which is beneficial to improve the processing efficiency of the coolant and debris.

[0007] Preferably, one end of the drain pipe away from the collecting tank is connected to a pumping mechanism, and the pumping mechanism is used to extract the coolant in the collecting tank.

[0008] By adopting the above technical solution, the coolant in the collection tank can be quickly sucked out under the drive of the pumping mechanism, which is beneficial for the collection tank to always maintain sufficient accommodation space and reduce the situation where the coolant overflows the collection tank.

[0009] Preferably, the collecting tank is divided into a plurality of compartments, and the plurality of compartments are all connected to a drainage pipe.

[0010] By adopting the above technical solution, when the base of the machine tool adopts an inclined work table, the coolant is quickly concentrated on one side of the collection tank under the influence of its own gravity, making it difficult to utilize all the space in the collection tank. There is a risk of coolant overflow. By dividing the collection tank into multiple compartments, the coolant can be collected independently. The compartments are connected to the drain pipe to discharge the coolant in time, which is beneficial to improve the space utilization of the collection tank.

[0011] Preferably, the foldable baffle is bent toward the collecting groove at one side close to the collecting groove and connected with the notch edge of the collecting groove.

[0012] By adopting the above technical solution, by bending the side of the foldable baffle close to the collecting groove, the foldable baffle is made to be at a certain angle and connected with the edge of the groove of the collecting groove, which is conducive to the coolant on the surface of the foldable baffle to be smoothly guided into the collecting groove and reduce the leakage of the coolant.

[0013] Preferably, the foldable baffle comprises a plurality of baffle units connected in sequence, and elastic members are arranged between adjacent baffle units.

[0014] By adopting the above technical solution, the foldable baffle is divided into a plurality of baffle units connected in sequence. While improving the telescopic flexibility of the foldable baffle, adjacent baffle units are also connected by elastic parts. Under the interaction of multiple elastic parts, the stability of the foldable baffle is improved as a whole, and the situation of excessive concave of the foldable baffle under its own gravity and the gravity of the coolant is improved, which is conducive to maintaining the connection between the foldable baffle and the collection tank.

[0015] Preferably, it further comprises a plurality of push-pull assemblies, which are disposed at two working parts on the slide rail and act on both ends of the foldable baffle respectively, and the push-pull assemblies adjust the downward bending degree of both sides of the foldable baffle by pushing and pulling.

[0016] By adopting the above technical scheme, a push-pull assembly is installed on the working part, and the pushing and pulling methods of the push-pull assembly are used to adjust the downward bending degree of the two sides of the foldable baffle, so that the bending shape of the foldable baffle can be adjusted according to the processing conditions. For example, when coolant is used for workpiece cutting, the side of the foldable baffle can be pressed down to the collection groove through the push-pull assembly and connected with the edge of the collection groove, thereby facilitating the diversion and collection of the coolant. When coolant is not needed for workpiece cutting, the downward bending degree of the foldable baffle can be increased, so that the two sides of the foldable baffle are bent to the two sides of the slide rail, thereby wrapping the slide rail as a whole, which is beneficial to reduce the situation where flying debris falls to the two sides of the slide rail, and is beneficial to improve the applicability of the foldable baffle.

[0017] Preferably, the push-pull assembly includes an electric push rod and a pressure plate connected to the telescopic end of the electric push rod through a ball joint, the pressure plate is connected to the surface of the side of the foldable baffle, and the electric push rod presses down the side of the foldable baffle by extending in the direction of the slide rail.

[0018] By adopting the above technical solution, the pressure plate is connected to the telescopic end of the electric push rod by a ball joint, and the surface of the pressure plate and the foldable baffle are connected. When the electric push rod is extended toward the slide rail, the pressure plate presses down on the side of the foldable baffle. The angle between the pressure plate and the electric push rod can be changed according to the force, which is conducive to bending the side of the foldable baffle toward one side of the slide rail.

[0019] A chip collection method for a double-station CNC machine tool, using a chip collection device for a double-station CNC machine tool, comprising the following steps: The foldable baffle blocks the surface of the slide rail. When the workpiece is processed, the coolant and debris fall onto the surface of the foldable baffle. The foldable baffle folds and expands as the two working parts on the slide rail move relative to each other. Multiple guide grooves formed on the surface of the foldable baffle in the folded state collect the coolant and guide it into the collection tank. The collection tank discharges the coolant and debris through the drain pipe.

[0020] By adopting the above technical scheme, the foldable baffle can be folded and retracted as the two working parts on the slide rail move relative to each other, which is beneficial to maintaining the shielding effect on the slide rail without affecting the normal movement of the working parts of the machine tool. The guide groove formed on the surface of the foldable baffle has a collecting and guiding effect on the coolant, so that the coolant can be smoothly drained into the collection tank, which is beneficial to improving the processing efficiency of the coolant and debris.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. By installing the two ends of the foldable baffle between the two working parts on the corresponding slide rail and covering the corresponding slide rail surface, the slide rail is shielded, reducing the coolant and debris from falling directly on the slide rail, which is conducive to improving the situation where the debris is stuck on the slide rail; 2. The foldable baffle can be folded and retracted as the two working parts on the slide rail move relative to each other, which is beneficial to maintain the shielding effect on the slide rail without affecting the normal movement of the working parts of the machine tool. The folded state of the foldable baffle forms multiple guide grooves, which have a collection and guiding effect on the coolant, so that the coolant can be smoothly drained into the collection tank, which is beneficial to improve the processing efficiency of the coolant and debris; 3. By installing a push-pull assembly on the working part, the downward bending degree of both sides of the foldable baffle is adjusted by using the push and pull method of the push-pull assembly, so that the bending shape of the foldable baffle can be adjusted according to the processing conditions. The side of the foldable baffle is pressed down to the collecting groove by the push-pull assembly to connect with the edge of the collecting groove, so as to facilitate the diversion and collection of the coolant. By increasing the downward bending degree of the foldable baffle, the two sides of the foldable baffle are bent to the two sides of the slide rail, so as to wrap the slide rail as a whole, which is conducive to reducing the situation where scattered debris falls to both sides of the slide rail, and is conducive to improving the applicability of the foldable baffle; 4. By dividing the foldable baffle into multiple baffle units connected in sequence and connecting adjacent baffle units through elastic members, the interaction of multiple elastic members is beneficial to improving the stability of the foldable baffle as a whole, and when the push-pull component presses down the end of the foldable baffle, the elastic member can act on the middle of the foldable baffle, thereby improving the control and adjustment of the bending angle of the middle position of the foldable baffle by the push-pull component.

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] The present application discloses a chip collection device and method for a double-station CNC machine tool, referring to Figure 1 The machine tool structure includes a base 1, two pairs of slide rails 2 installed on the working surface of the base 1, and a working component 3 slidably connected to the slide rails 2, wherein the working surface of the base 1 is inclined at 45 degrees, and the two pairs of slide rails 2 are distributed up and down and extend horizontally. There are two working components 3 sliding on each pair of slide rails 2, namely a turret structure and a spindle assembly, the spindle assembly is used to clamp the workpiece, and the turret structure is used to process the workpiece.

[0029] Reference Figure 2 and Figure 3 The chip collecting device includes a plurality of foldable baffles 4 for covering the surface of the slide rail 2 and a collecting trough 6 arranged between two adjacent slide rails 2. The foldable baffles 4 correspond to the slide rails 2 one by one. The two ends of the foldable baffles 4 are connected between the two working components 3 on the corresponding slide rails 2 through rubber strips 43 respectively, wherein the middle part of the rubber strip 43 is fixed to the end surface of the working component 3 by screws, and the two ends of the rubber strip 43 are movable.

[0030] The foldable baffle 4 includes a plurality of baffle units 41 connected in sequence, and the foldable baffle 4 can be folded or unfolded along the length direction of the slide rail 2. The foldable baffle 4 can be folded and retracted as the two working parts 3 on the slide rail 2 move relative to each other, which is beneficial to maintain the shielding effect on the slide rail 2 without affecting the normal movement of the machine tool working parts 3. In this embodiment, the foldable baffle 4 is a paper sheet with a waterproof film on the surface, and the paper sheet can have a certain hardness so as to support the falling coolant, and the paper sheet can be bent under the downward pressure.

[0031] An elastic member 42 is connected between adjacent baffle units 41. In the present embodiment, the elastic member 42 is an elastic rope, which can improve the contraction ability of the foldable baffle 4 and improve the overall stability of the foldable baffle 4, thereby improving the situation where the foldable baffle 4 is excessively concave under the action of its own gravity and the gravity of the coolant.

[0032] In this embodiment, the collecting trough 6 is fixed on the work surface of the base 1 and extends horizontally, distributed in the gap between the two slide rails 2. In addition, a collecting trough 6 is also installed at the inclined lower end of the base 1. The two collecting troughs 6 respectively collect the coolant received by the foldable baffles 4 above the two slide rails 2, and the side of the foldable baffles 4 extends to the corresponding notches of the collecting troughs 6. The folded state of the foldable baffles 4 forms a plurality of guide grooves, which can not only collect the coolant splashed on the surface of the foldable baffles 4 and guide it into the collecting trough 6, but also independently collect the coolant so that the foldable baffles are balanced.

[0033] In this embodiment, a drain pipe is connected to the bottom of the collecting tank 6, and the collecting tank 6 discharges the coolant and the debris out of the machine tool through the drain pipe, which is beneficial to improving the processing efficiency of the coolant and the debris.

[0034] Since the base 1 of the machine tool adopts an inclined worktable, the coolant is quickly concentrated on one side of the collection tank 6 under the influence of its own gravity, so it is difficult to use all the space in the collection tank 6, and there is a risk of coolant overflow. The collection tank 6 is divided into a plurality of compartments 61, and the plurality of compartments 61 are connected to the drainage pipe. The plurality of compartments 61 can independently collect the coolant, and the compartments 61 are connected to the drainage pipe to discharge the coolant in time, which is conducive to improving the space utilization rate of the collection tank 6.

[0035] In this embodiment, a pumping mechanism is connected to one end of the drain pipe away from the collecting tank 6, and the pumping mechanism is used to extract the coolant in the collecting tank 6. The pumping mechanism uses a conventional pumping pump and a filter box, and the coolant is sucked into the filter box by the pumping pump. The filter box can filter the coolant to facilitate the recycling of the coolant. In addition, the pumping pump can quickly suck the coolant in the collecting tank 6 clean, which is conducive to the collecting tank 6 always maintaining sufficient accommodation space and reducing the situation where the coolant overflows the collecting tank 6.

[0036] Reference Figure 3 and Figure 4In this embodiment, the chip collecting device further includes a plurality of push-pull assemblies 5, which are disposed at two working parts 3 on the slide rail 2 and act on the two ends of the foldable baffle 4 respectively. The push-pull assemblies 5 adjust the downward bending degree of the two sides of the foldable baffle 4 by pushing and pulling. Specifically, the push-pull assembly 5 includes an electric push rod 51 and a pressure plate 52 connected to the telescopic end of the electric push rod 51 through a ball joint. The electric push rod 51 is arranged perpendicular to the working surface of the base 1 and close to the side of the slide rail 2. The pressure plate 52 is connected to the surface of the side of the rubber strip 43 of the foldable baffle 4, and the electric push rod 51 presses down the side of the foldable baffle 4 by extending toward the slide rail 2. During the pressing process, the pressing plate 52 swings toward the side of the slide rail 2 to adjust the degree of bending of the foldable stopper 4. At the same time, a protrusion can be fixed on the end surface of the working part 3, and the protrusion is located below the foldable stopper 4. While pushing the end of the foldable stopper 4 to play a supporting role, it can also work with the push-pull assembly 5 on the foldable stopper 4 to increase the degree of bending of the side of the foldable stopper 4. In this way, the bending shape of the foldable stopper 4 can be adjusted according to the processing conditions. For example, when the coolant is used for workpiece cutting, the side of the foldable stopper 4 can be pressed down to the collecting tank 6 by the push-pull assembly 5 to connect with the edge of the collecting tank 6, so as to facilitate the diversion and collection of the coolant. When the coolant is not needed for workpiece cutting, the downward bending degree of the foldable stopper 4 can be increased, so that the two sides of the foldable stopper 4 are bent to the two sides of the slide rail 2, thereby wrapping the slide rail 2 as a whole, which is conducive to reducing the situation where the scattered debris falls to the two sides of the slide rail 2, and is conducive to improving the applicability of the foldable stopper 4.

[0037] A chip collection method for a double-station CNC machine tool adopts a chip collection device for a double-station CNC machine tool, wherein a foldable baffle 4 blocks the surface of a slide rail 2. When a workpiece is processed, coolant and debris fall onto the surface of the foldable baffle 4. The foldable baffle 4 folds and retracts as the two working components 3 on the slide rail 2 move relative to each other. A plurality of guide grooves formed on the surface of the foldable baffle 4 in the folded state collect the coolant and guide it into a collection tank 6. The collection tank 6 discharges the coolant and debris through a drain pipe, and accelerates the discharge speed of the coolant in the collection tank 6 through a pumping mechanism. It should be emphasized that in order to achieve full coverage of the slide rail 2, a foldable baffle 4 can also be arranged between the inner side wall of the machine tool body and the rear end face of the working component 3.
