Description

Technical Field

[0001] The present application relates to the technical field of numerically controlled machine tools, and in particular to a positioning and flipping device for numerically controlled machine tools. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process the parts according to the shape and size required by the drawing.

[0003] CNC machine tools usually have a positioning seat for positioning parts. When a part needs to be processed, the worker first fixes the part on the positioning seat, and then the CNC machine tool processes it. However, some specific parts need to be processed on both sides. During the processing of these specific parts, the worker needs to first fix the part on the positioning seat for the first processing, then take the part out of the positioning seat, flip it 180°, and then fix it on the positioning seat for the second processing. This process is cumbersome and greatly reduces the processing efficiency of the parts. This problem needs to be solved urgently. Utility Model Content

During the processing of the front and back sides of the part, there is no need to repeatedly take and place the part on the supporting plate, the operation is simple, which is beneficial to improve the processing efficiency of parts that need to be processed on both the front and back sides.

[0009] By adopting the above technical solution, the output shaft of the driving motor drives the driving rod to rotate, and the rotating driving rod drives the carrying plate to perform a flipping operation, and the flipping operation of the carrying plate is simple and convenient.

[0010] Preferably, the braking mechanism includes a locking gear, a locking rod and a driving assembly, the locking gear is fixedly sleeved on the driving rod, and the driving assembly is installed on the mounting seat to drive the locking rod to move toward or away from the locking gear. When the locking rod is close to the locking gear, the locking rod is locked into the tooth gap of the locking gear.

[0011] By adopting the above technical solution, when the part is subjected to the first processing operation, the driving component drives the clamping rod to be close to the clamping gear, so that the clamping rod is clamped into the tooth gap of the clamping gear, which is beneficial to improve the stability of the part during the first processing operation. When the first processing operation of the part is completed, during the process of the supporting plate flipping 180°, the driving component drives the clamping rod away from the clamping gear so that the supporting plate can be flipped. When the flipping operation of the supporting plate is completed, the driving component drives the clamping rod close to the clamping gear again, so that the clamping rod is clamped into the tooth gap of the clamping gear again, which is beneficial to improve the stability of the part during the second processing operation.

[0013] By adopting the above technical scheme, the upper support plate and the lower support plate support the support rod, the sleeve block, the connecting rod, the driving cylinder and the clamping rod. When the driving cylinder drives the sleeve block to move vertically downward along the length direction of the support rod, the sleeve block drives the clamping rod to move in the direction close to the clamping gear through the connecting rod, thereby fixing the load-bearing plate. When the driving cylinder drives the sleeve block to move vertically upward along the length direction of the support rod, the sleeve block drives the clamping rod to move in the direction away from the clamping gear through the connecting rod, thereby releasing the fixation of the load-bearing plate.

During the processing of the front and back sides of the parts, there is no need to repeatedly take and place the parts on the carrying plate, the operation is simple, and thus it is beneficial to improve the processing efficiency of parts that need to be processed on both the front and back sides.

[0024] 2.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a positioning and flipping device for a CNC machine tool, referring to Figure 1 , including a bearing plate 1 and two mounting seats 2, the two mounting seats 2 support the bearing plate 1, and the bearing plate 1 is flipped and connected to a position between the two mounting seats 2.

[0033] Reference Figure 1 , the carrier plate 1 is provided with a fixing mechanism for fixing the parts. Specifically, the fixing mechanism includes an air suction hole 6 and a vacuum suction system (not shown in the figure), the air suction hole 6 is provided on the board surface of the carrier plate 1, and the air suction hole 6 is connected to the vacuum suction system. When the parts need to be processed, the staff places the parts on the board surface of the carrier plate 1 and covers the air suction hole 6, and the vacuum suction system generates a vacuum negative pressure through the air suction hole 6 so that the parts are adsorbed and fixed on the board surface of the carrier plate 1. Furthermore, an air expansion groove 7 is provided around the side of the air suction hole 6, and the air expansion groove 7 is connected to the air suction hole 6 to improve the adsorption force of the vacuum suction system on the parts through the air suction hole 6, thereby helping to improve the stability of the parts when they are fixed on the carrier plate 1. In addition, a protective pad layer 8 is attached to the board surface of the carrier plate 1. In this embodiment, the protective pad layer 8 is selected as a silicone pad.

[0034] Reference Figure 1 and Figure 2The mounting seat 2 is provided with a driving mechanism 3. In order to reduce the space occupied by the driving mechanism 3, the driving mechanism 3 is arranged inside the mounting seat 2. The driving mechanism 3 is used to drive the carrier plate 1 to flip, and the flip angle of the carrier plate 1 is 180°. Specifically, the driving mechanism 3 includes a driving motor 31 and a driving rod 32. The driving motor 31 is horizontally fixedly connected to the mounting seat 2, and the driving rod 32 is horizontally rotatably connected to the mounting seat 2. One end of the driving rod 32 is fixedly connected to the edge of the carrier plate 1, and the other end of the driving rod 32 is coaxially fixedly connected to the output shaft of the driving motor 31, so that the rotation of the output shaft of the driving motor 31 can drive the carrier plate 1 to flip through the driving rod 32.

[0035] Reference Figure 1 and Figure 3 The mounting seat 2 is also provided with a brake mechanism 4, which is used to position the carrier plate 1 after flipping 180 degrees. Specifically, the brake mechanism 4 includes a clamping gear 41, a clamping rod 42 and a driving assembly 43. The clamping gear 41 is fixedly sleeved on one end of the driving rod 32 close to the driving motor 31. The driving assembly 43 is installed inside the mounting seat 2 and is used to drive the clamping rod 42 to move horizontally toward or away from the clamping gear 41. When the clamping rod 42 is close to the clamping gear 41, the clamping rod 42 is clamped into the tooth gap of the clamping gear 41. When the carrier plate 1 needs to be flipped, the driving component 43 drives the clamping rod 42 to move in the direction away from the clamping gear 41, so that the carrier plate 1 can be flipped under the drive of the driving mechanism 3; after the carrier plate 1 is flipped 180°, the driving component 43 drives the clamping rod 42 to move in the direction close to the clamping gear 41, so that the clamping rod 42 is clamped in the tooth gap of the clamping gear 41, and the carrier plate 1 cannot continue to flip, thereby facilitating the subsequent second processing operation of the parts by the CNC machine tool.

[0036] Reference Figure 3The driving assembly 43 includes an upper support plate 431, a lower support plate 432, a support rod 433, a sleeve block 434, a linkage rod 435 and a driving cylinder 436. The upper support plate 431 and the lower support plate 432 are horizontally fixedly connected to the inner side wall of the mounting seat 2, and the upper support plate 431 is located directly above the lower support plate 432. The support rod 433 is vertically arranged, and the upper end of the support rod 433 is fixedly connected to the lower surface of the upper support plate 431, and the lower end of the support rod 433 is fixedly connected to the upper surface of the lower support plate 432. The sleeve block 434 is movably sleeved on the support rod 433 and moves vertically up and down along the length direction of the support rod 433. One end of the linkage rod 435 is rotatably connected to the side wall of the sleeve block 434, and the other end of the linkage rod 435 is rotatably connected to the side wall of the clamping rod 42, and the clamping rod 42 is horizontally movably arranged on the lower support plate 432. The driving cylinder 436 is fixedly disposed on the lower plate surface of the upper support plate 431 , and the piston rod of the driving cylinder 436 is vertically disposed downward, and the sleeve block 434 is fixedly connected to the piston rod of the driving cylinder 436 .

[0037] When the piston rod of the driving cylinder 436 is stretched, the piston rod of the driving cylinder 436 drives the sleeve block 434 to move vertically downward, and the sleeve block 434 moving vertically downward drives the clamping rod 42 to move horizontally toward the clamping gear 41 through the connecting rod 435, so that the clamping rod 42 can be clamped into the tooth gap of the clamping gear 41 to achieve positioning; when the piston rod of the driving cylinder 436 is contracted, the piston rod of the driving cylinder 436 drives the sleeve block 434 to move vertically upward, and the sleeve block 434 moving vertically upward drives the clamping rod 42 to move horizontally toward the direction away from the clamping gear 41 through the connecting rod 435, thereby releasing the positioning of the supporting plate 1.

[0038] Reference Figure 1 The carrier plate 1 is provided with avoidance holes 5 for the CNC machine tool to process the front and back sides of the part. After the CNC machine tool completes the front side processing operation of the part, the carrier plate 1 is turned 180°, and then the CNC machine tool processes the back side of the part through the avoidance holes 5. It should be noted that the air suction holes 6 surround the side of the avoidance holes 5, so that the suction function of the air suction holes 6 on the part and the avoidance function of the avoidance holes 5 do not interfere with each other.

[0039] The implementation principle of a positioning and flipping device for a CNC machine tool in an embodiment of the present application is as follows: when it is necessary to process both the front and back sides of a part, the staff first places the part on a carrier plate 1 so that the front side of the part faces upward, and the vacuum suction system fixes the part on the carrier plate 1 through the suction hole 6, and then the CNC machine tool performs the first processing operation on the front side of the part. After the first processing operation on the front side of the part is completed, the piston rod of the driving cylinder 436 is retracted to drive the sleeve 434 to move vertically upward, and the sleeve 434 moving vertically upward drives the clamping rod 42 to move horizontally in the direction away from the clamping gear 41 through the connecting rod 435, thereby releasing the positioning of the carrier plate 1, and the driving motor 31 drives the carrier plate 1 to flip 180° through the driving rod 32, so that the back side of the part faces upward, and then the piston rod of the driving cylinder 436 is stretched to drive the sleeve 434 to move vertically downward, and the sleeve 434 moving vertically downward drives the clamping rod 42 to move horizontally in the direction close to the clamping gear 41 through the connecting rod 435, so that the clamping rod 42 is clamped into the tooth gap of the clamping gear 41 to achieve positioning, so that the CNC machine tool can perform the second processing operation on the back side of the part. In the process of processing the front and back sides of the part, it is not necessary to repeatedly take and place the part on the carrier plate 1, and the operation is simple, which is conducive to improving the processing efficiency of the parts that need to be processed on both the front and back sides.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
