Description

Technical Field

[0001] The present application belongs to the technical field of mechanical processing equipment, and in particular, relates to a four-axis processing equipment. Background Art

[0002] At present, in the domestic manufacturing industry, multi-faceted workpieces need to be processed during the processing, and these multi-faceted non-coaxial surfaces are usually processed using five-axis processing equipment. However, for a small number of processing parts, the cost of using five-axis processing equipment is too high and it occupies production resources. In this regard, four-axis processing equipment is generally used for two clamping to replace the processing method of five-axis processing equipment. Therefore, two four-axis processing equipment are required, and the workpiece is transferred between the two four-axis processing equipment for secondary clamping.

[0003] It can be seen that this method is not only complicated to operate, but also after the second clamping, the fixed position of the processing part is prone to deviation, resulting in defects in the finished product after processing, affecting product quality. In addition, when there are fewer processing parts on each axis surface, the operator needs to load and unload materials frequently, which makes the operator very easy to get tired. It is not suitable for batch processing, and the labor cost investment is not proportional. Summary of the invention

[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0045] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0046] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0047] In the production operation of multi-faceted processing, for workpieces with fewer processing parts, if the five-axis processing equipment is used, the cost is too high and it occupies production resources, so the four-axis processing equipment is used instead. However, the use of four-axis processing equipment requires the installation of two units and requires two clamping operations. The staff needs to switch between the two devices and perform loading and unloading operations, which is very cumbersome.

[0048] As an example, Figure 1 The workpiece 100 shown has a processing requirement of one groove and one hole, specifically, a groove X and a through hole Y are processed on different processing surfaces of the workpiece 100 respectively. Since the tool on the commonly used CNC processing head adopts a top-down cutting method, the workpiece 100 is fixed below the tool, and the tool can only be driven by the CNC processing head to move horizontally. Therefore, corresponding to the above two cutting processing actions, two clampings are required to make the processing parts of the workpiece 100 respectively under the tool and facing the tool. Specifically, for the processing of the groove X on the workpiece 100, the workpiece 100 needs to be arranged vertically so that the tool can cut the groove from top to bottom. For the through hole Y on the workpiece 100, the through hole Y is a side opening of the upper half of the workpiece 100, and the lower half of the workpiece 100 is inclined with respect to the upper half. Since the clamped and fixed part is the lower half of the workpiece 100, it is necessary to set the workpiece 100 horizontally and then roll and rotate the workpiece 100 at a certain angle so that the tool can be perpendicular to the top of the through hole Y, so as to facilitate the tool to cut directly into the hole.

[0049] It can be seen that the above-mentioned processing using traditional four-axis processing equipment is very complicated. After the secondary clamping, the fixed position of the processing part is also prone to deviation, which leads to defects in the processed workpiece 100 and affects the product quality.

[0050] The embodiment of the present application provides a new type of four-axis machining equipment to solve the problem that the traditional four-axis machining equipment needs secondary clamping to meet the processing method of the five-axis machining equipment, which makes the machining process complicated, requires large labor and equipment investment, and is not conducive to batch processing. It is now described in detail.

[0051] See also Figure 2The four-axis machining equipment includes a workbench 200 and a CNC machining head 300. The CNC machining head 300 is provided with a tool 301. The CNC machining head 300 is located above the workbench 200. The tool 301 on the CNC machining head 300 can perform cutting or drilling on the workpiece 100 clamped on the workbench 200 from top to bottom.

[0052] Please also read Figure 2 , Figure 3 and Figure 4 The workbench 200 is preferably a mobile machine set on a conventional CNC machine base 400, and the workbench 200 is provided with a flipping device 1 and a rotating seat 2 for clamping the workpiece 100. In this embodiment, the flipping device 1 is equivalent to a single-side driving seat on a conventional four-axis machining device, and an output terminal 11 is provided on the side of the flipping device 1.

[0053] like Figure 4 As shown, the rotating seat 2 is arranged on the output end 11 of the flipping device 1, and the rotating seat 2 extends horizontally from the output end 11 to the first direction F, and the flipping device 1 is used to drive the rotating seat 2 to roll and rotate. The "first direction F" here can be understood as the axial direction S of the output end 11 of the flipping device 1, and the axial direction S is parallel to the surface M of the workbench 200.

[0054] The rotating seat 2 is provided with a driver 3 and a swing arm 4, and the two ends of the swing arm 4 are respectively provided with a fixed end 41 and a free end 42. The driver 3 is connected to the fixed end 41 of the swing arm 4 through a linkage mechanism, and the free end 42 of the swing arm 4 is provided with a clamping jaw 5 for mounting the workpiece 100. The driver 3 drives the swing arm 4 to rotate and swing in the first direction F mentioned above, so that the swing arm 4 can stand upright below the tool 301, or be arranged horizontally below the tool 301, thereby changing the axial surface of the workpiece 100 arranged on the clamping jaw 5.

[0055] Compared with the prior art, the four-axis processing equipment provided by the embodiment of the present application is that the workpiece 100 only needs to be clamped on the swing arm 4 of the rotating seat 2 once, and the driver 3 can drive the swing arm 4 to rotate and swing, so as to change the two axial surfaces of the workpiece 100, so that the workpiece 100 can be switched between the vertical setting and the horizontal setting, so as to meet the requirements of multi-faceted processing. In this way, it is not necessary to disassemble the workpiece 100 after the first axial surface of the workpiece 100 is processed, transfer it to another four-axis processing equipment for re-clamping, and then process the second axial surface of the workpiece 100, which effectively improves the processing efficiency.

[0056] Since there is no need for secondary clamping, the workpiece 100 always remains in the original clamping position, thereby eliminating the problem of deviation of the clamping position caused by secondary clamping, ensuring the consistency of the fixed posture of the workpiece 100 and effectively improving the quality of the finished product.

[0057] In addition, the turning device 1 is used to drive the rotating seat 2 to roll and rotate to correct the axial direction of the workpiece 100, thereby increasing the fine-tuning function of the processed surface, which is beneficial to meeting the processing requirements of inclined surfaces and further improving the adjustability of the equipment.

[0058] In this embodiment, the processing requirements of the workpiece 100 are as follows: Figure 3 and Figure 4 As shown, the blank is clamped on the clamping jaw 5 of the free end 42 of the swing arm 4, and then the CNC machining head 300 is started to start the tool 301 to cut the machining part on the first axial surface of the blank to obtain the groove X.

[0059] Then, if Figure 4 and Figure 5 As shown, the driver 3 drives the swing arm 4 to rotate and swing in the first direction F, so that the swing arm 4 changes from the vertical direction to the horizontal direction, so that the second axial surface of the blank faces the CNC machining head 300 .

[0060] like Figure 6 As shown, the turning device 1 drives the rotating seat 2 to make the swing arm 4 roll and rotate to adjust the tilt angle, and then cuts the processing position on the second axial surface of the blank to open a through hole Y. After the processing is completed, the driver 3 drives the swing arm 4 to reset, remove the finished product and replace it with a new blank for a new round of operation.

[0061] It can be seen that the entire processing process only requires one device to be clamped once, and the processing of the two processing parts on different axial surfaces of the workpiece 100 can be completed in one go, which is simple to operate. The technical problem of the deviation of the fixed position of the processing part of the workpiece 100 caused by secondary clamping, which affects the quality of the finished product, is eliminated, and the processing quality is effectively improved.

[0062] The four-axis machining equipment of the present application simplifies the structure of the traditional four-axis machining device, adopts the design of a single-sided drive base, and only sets a single-sided flip device 1, which directly uses the single-sided flip device 1 to drive the horizontally arranged rotating base 2 to roll and rotate. The driver 3 on the rotating base 2 can drive the swing arm 4 to rotate to quickly complete the work surface conversion of the workpiece 100, meeting the processing requirements of a small and lightweight workpiece 100 with fewer work surfaces. It can be seen that one device can complete the functions of the original two four-axis machines with double-sided drive bases, effectively reducing production costs.

[0063] For the linkage mechanism between the driver 3 and the swing arm 4, in the embodiment of the present application, please refer to Figure 7 The linkage mechanism includes a rack 6 and a gear portion 411 disposed on the fixed end 41 of the swing arm 4, and the rack 6 meshes with the gear portion 411. It can be understood here that: a circle of convex teeth is provided on the fixed end 41 of the swing arm 4, and the convex teeth of the circle constitute the gear portion 411, and the rack 6 meshes with the convex teeth of the gear portion 411.

[0064] The driver 3 may preferably be a linear cylinder, the output shaft 31 of which is connected to the rack 6 and drives the rack 6 to move linearly, thereby driving the swing arm 4 to rotate and swing.

[0065] In this way, the teeth engagement force between the rack 6 and the gear part 411 is utilized to facilitate the swing arm 4 to arbitrarily hover within the swing range, and automatically lock the rotation angle of the swing arm 4, so that the swing arm 4 can swing stably and automatically position. There is no need to install a mechanism to lock the swing amplitude of the swing arm 4, which effectively saves the space occupied by installing an additional mechanism.

[0066] In other embodiments (not shown), a gear set may be used, or a combination of a gear set and a transmission belt may be used, or the driver 3 may even be directly connected to the swing arm 4. Any structure that can drive the swing arm 4 to swing and rotate is acceptable and is not specifically limited here.

[0067] For the structure of the rotating seat 2, please refer to the embodiment of the present application. Figure 8 and Fig. 9 The rotating seat 2 includes a bracket 21 and fixing plates 22 installed on both sides of the bracket 21. The fixing plates 22 can be fixed on both sides of the bracket 21 by adding fasteners such as screws.

[0068] The swing arm 4 is disposed on the bracket 21 and is located between the fixing plates 22 on both sides of the bracket 21. A rotating shaft 412 is also disposed on the fixing end 41 of the swing arm 4, and an axial hole 221 is provided on the fixing plate 22. The rotating shaft 412 on the swing arm 4 is plugged into the axial hole 221 of the fixing plate 22, so that the swing arm 4 can rotate and swing on the bracket 21 with the rotating shaft 412 as the axis.

[0069] In this way, the rotation direction of the swing arm 4 on the rotating seat 2 is limited, so that the swing arm 4 can be perpendicular to the axis of the bracket 21 when vertical, and can be parallel to the axis of the bracket 21 when horizontal, avoiding the swing arm 4 from exceeding the range of the CNC machining head 300 driving the tool 301 to move horizontally.

[0070] In one embodiment of the present application, please refer to Fig. 9 and Fig.10 The bracket 21 is provided with a mounting seat 211 and a through slot 212 for arranging the rack 6, and the mounting seat 211 is provided with a communication port 213 communicating with the through slot 212. In this embodiment, the mounting seat 211 has a C-shaped mounting portion, and the fixed end 41 of the swing arm 4 is embedded in the C-shaped mounting portion, and the communication port 213 is an opening on the mounting portion that partially surrounds the outer periphery of the fixed end 41 of the swing arm 4.

[0071] The swing arm 4 is arranged on the mounting seat 211, and the gear part 411 on the swing arm 4 is located at the communication port 213. The rack 6 is received in the through slot 212 of the bracket 21. When the driver 3 drives the rack 6 to move, the rack 6 moves linearly in the through slot 212, and the teeth on the rack 6 are exposed from the communication port 213 and meshed with the gear part 411, thereby driving the swing arm 4 to rotate.

[0072] It can be seen that the linkage mechanism between the driver 3 and the swing arm 4 has a simple and compact structure and can be easily installed on the rotating base 2 .

[0073] Please also read Figure 8 , Fig. 9 and Fig.10 A fixing frame 214 for mounting the driver 3 is also provided at the bottom of the bracket 21 , and a first mounting hole 215 is opened on the fixing frame 214 .

[0074] One end of the rack 6 has a connecting portion 61 extending to the fixing frame 214 , and specifically, the connecting portion 61 may be provided on an end away from the connecting port 213 of the mounting seat 211 .

[0075] The driver 3 is fixedly connected to the fixing frame 214 , and the output shaft 31 of the driver 3 passes through the first mounting hole 215 on the fixing frame 214 and is connected to the connecting portion 61 of the rack 6 .

[0076] In this embodiment, if Fig. 9 and Fig.10 As shown, the fixing frame 214 is an L-shaped frame, including a vertical plate and a horizontal plate, and the vertical plate is provided with the first mounting hole 215 and the first fixing hole for mounting and connecting with the driver 3. The horizontal plate is provided with a second fixing hole connected with the bottom of the bracket 21, and the horizontal plate is provided with an avoidance groove for the connecting portion 61 of the rack 6 to pass through and approach the first mounting hole 215 of the vertical plate. The connecting portion 61 is provided with a connecting hole 62, which is used to correspond to the position of the first mounting hole 215, so that the output shaft 31 of the driver 3 can pass through the first mounting hole 215 and be fixed to the connecting hole 62 on the connecting portion 61 by fasteners such as screws or bolts.

[0077] In this way, the driver 3 is compactly fixed on the bracket 21, reducing the occupied space. In particular, the structure of the single-sided flip device 1 of the present application is conducive to reducing the weight of the rotating base 2, avoiding the rotating base 2 being too heavy and affecting the balance.

[0078] Preferably, in the embodiments of the present application, please refer to Fig. 9 , Fig.11 and Fig.12The fixed plate 22 is also provided with an arc groove 222 for limiting the swing trajectory of the swing arm 4. The swing arm 4 is provided with a limit shaft 43, which is protruding from the swing arm 4 and can be embedded in the arc groove 222 of the fixed plate 22.

[0079] In this way, the swing arm 4 is embedded in the arc groove 222 with the limiting shaft 43 and swings along the groove shape of the arc groove 222, thereby limiting the swing amplitude of the swing arm 4.

[0080] In one embodiment of the present application, see Figure 8 A track cover 23 for limiting the swing range of the swing arm 4 is provided on the bracket 21. A groove rail 231 is provided on the track cover 23. The free end 42 of the swing arm 4 passes through the groove rail 231 and can move in the groove rail 231, thereby limiting the swing trajectory of the swing arm 4 and preventing the swing arm 4 from tilting sideways during the swinging process.

[0081] In this embodiment, the track cover 23 is a corner piece on the extended end of the rotating seat 2, which is a frame structure, and the groove rail 231 is equivalent to an L-shaped track on the corner frame. Therefore, it is preferred to limit the swing amplitude of the swing arm 4 to within 90 degrees, so that the swing arm 4 can be set vertically or horizontally to meet the processing requirements.

[0082] See also Figure 8 The track cover 23 is also provided with a stretchable dust cover 232, which covers the groove track 231. The dust cover 232 is provided with a through hole 233, and the clamping claw 5 on the swing arm 4 passes through the through hole 233.

[0083] The dust cover 232 may preferably be an elastic shielding member such as an accordion protective cover or an accordion flexible shielding plate. The dust cover 232 is installed on the track cover 23 through a fixed pressing member 234, and can keep shielding the opening on the groove track 231 during the movement of the swing arm 4 to ensure a sealing effect.

[0084] For the structure of the clamping jaw 5, Figure 7 As shown, the clamping jaw 5 can be integrally connected to the free end 42 of the swing arm 4, or can be detachably arranged on the free end 42 of the swing arm 4, so that the clamping jaw 5 of different specifications can be replaced according to different shapes of the workpiece 100 or clamping requirements.

[0085] In the embodiments of this application, please refer to Fig.12 and Fig.13 The clamping jaw 5 is a rectangular body, including two connected halves, with a joint seam 51 and a clamping groove 52 for mounting the workpiece 100 between the two halves, and the joint seam 51 is connected to the clamping groove 52.

[0086] Among them, the shape of the groove body of the clamping groove 52 can be set according to the shape of the workpiece 100, so that at least part of the workpiece 100 is embedded in the clamping groove 52, and the upper half of the workpiece 100 is exposed to the outside, and the clamping jaw 5 is used to clamp and fix the lower half of the workpiece 100 embedded in the clamping groove 52.

[0087] like Fig.12 and Fig.13 As shown, the clamping jaw 5 is also provided with an operating hole 53 for installing a fastener N, and the operating hole 53 penetrates from one half of the clamping jaw 5 to the other half of the clamping jaw 5 .

[0088] A fastener N such as a screw can extend from the operating hole 53 into the interior of the clamping jaw 5 to bring the two halves of the clamping jaw together to close the joint seam 51 , thereby clamping the workpiece 100 in the clamping groove 52 .

[0089] It can be seen that the structure of the clamping jaw 5 is very simple and easy to process and shape. The clamping operation only requires tightening or loosening the fastener N on the operating hole 53, which not only ensures the fixing effect of the workpiece 100, but also simplifies the clamping operation and improves the operating efficiency.

[0090] For the connection structure between the flip device 1 and the rotating seat 2, in one embodiment of the present application, please refer to Figure 8 , Fig.10 and Fig.14 A turntable 12 is also provided on the output end 11 of the flipping device 1 , and the rotating seat 2 is detachably provided on the turntable 12 and extends horizontally in the first direction F mentioned above.
