Description

Technical Field

[0001] The utility model relates to the technical field of CNC equipment, in particular to a CNC multi-position rotary processing fixture. Background Art

[0002] The feed path for a CNC lathe is the path the tool follows from the tool reference point (or the machine's fixed origin) until it returns to that point and the machining process ends. This includes both the cutting path and the non-cutting idle travel path, such as tool entry and exit. The feed path for finishing is essentially along the part wheel sequence, so determining the feed path focuses on determining the feed path for roughing and idle travel.

[0003] At present, in order to ensure the processing efficiency, CNC machines on the market are generally equipped with multiple stations when performing cutting processing. The products are installed on the stations, and the stations can be moved by a rotary table or some rotating mechanism to achieve smooth processing of the products. However, traditional products are generally fixed by squeezing and clamping the products during installation and fixing. In actual use, the following problems exist:

[0004] First, squeezing and clamping may cause scratches on the product surface, causing surface damage and affecting product quality. Secondly, after the product is processed, the debris generated is located on the surface or inside the clamping mechanism, affecting the next use. Therefore, a CNC multi-station rotary processing fixture is proposed to address the above problems. Utility Model Content

[0005] The purpose of the present invention is to provide a CNC multi-position rotary machining fixture to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: a CNC multi-station rotary processing fixture, comprising a rotary table, a mounting plate and a reinforcement plate,

[0007] The outer side of the rotating table is fixedly connected to a uniformly distributed mounting plate, the upper part of the mounting plate is fixedly connected to a support column, and the top of the support column is fixedly connected to a positioning plate, the inner side of the positioning plate is fixedly connected to a limiting cylinder, the bottom of the limiting cylinder is fixedly connected to a fixing mechanism, and the bottom of the fixing mechanism is connected to an air pipe, a guide frame and a guide cylinder are provided on the outer side of the air pipe, and the top of the guide frame is fixedly connected to the mounting plate, and the bottom of the guide frame is fixedly connected to the guide cylinder;

[0008] The fixing mechanism includes a fixing frame, a top cover and a placement plate. The outer side of the fixing frame is fixedly connected to the mounting plate, the top of the fixing frame is fixedly connected to the limiting cylinder, the interior of the fixing frame is rotatably connected to a hollow tube, and a fixing cylinder is installed at the bottom of the hollow tube. The outer side of the fixing cylinder is fixedly connected to the fixing frame, and the bottom of the fixing cylinder is connected to the air pipe.

[0009] The top of the hollow tube is connected to a placement tray.

[0010] Furthermore, the inner diameter of the top cover is consistent with the inner diameter of the limiting cylinder.

[0011] Furthermore, a rubber disc is fixedly connected to the top of the placement disc, and both the placement disc and the rubber disc are arranged in a disc shape.

[0012] At present, in order to ensure processing efficiency, CNCs on the market generally have multiple workstations when performing cutting processing. The product is installed on the workstation, and the workstation can be driven to move through a rotary table or some rotating mechanisms, thereby realizing smooth processing of the product. Traditional products are generally fixed by squeezing and clamping the product during installation and fixation. The following problems exist in actual use: first, squeezing and clamping may cause scratches on the surface of the product, causing surface damage and affecting product quality. Secondly, after the product is processed, the debris generated is located on the surface or inside of the clamping mechanism, affecting the next use. When this device is used, an external power supply is connected, and the product is placed inside the limit cylinder. When fixed, an air pump device on the outside of the air pipe is used for vacuuming. At this time, the bottom of the product is in contact with the rubber disc, and the product can be effectively fixed under negative pressure. This setting does not require squeezing to fix the product, which not only does not cause damage to the product surface, but also is very convenient to release.

[0013] Furthermore, ventilation holes are provided on the upper surfaces of the placement plate and the rubber plate, and the ventilation holes of the placement plate and the rubber plate are arranged to overlap.

[0014] Furthermore, a micro motor is fixedly connected to the interior of the fixed frame, a driving gear is fixedly connected to the end of the main shaft of the micro motor, and a driven gear is meshed on the outside of the driving gear, and the inside of the driven gear is fixedly connected to the hollow tube.

[0015] Furthermore, a sealing sleeve is fixedly connected to the outer side of the lower portion of the hollow tube, and a limiting ring fixedly connected to the fixing tube is provided below the sealing sleeve.

[0016] After the product is taken out, the external air pump equipment is used to exhaust the air. At this time, the air is discharged from the placement plate and the rubber plate, which can clean the inside of the limit cylinder and discharge the debris and impurities smoothly. The micro motor can drive the driving gear to rotate, and then the driven gear drives the hollow tube to rotate. The hollow tube can drive the placement plate and the rubber plate to rotate, so that the debris inside the limit cylinder is fully discharged, achieving the purpose of sufficient cleaning. When the hollow tube rotates, the sealing sleeve and the limit ring provided at the bottom of the hollow tube cooperate to play a certain sealing role, ensuring that the air passes through the fixed tube smoothly into the interior of the hollow tube.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] When the utility model is in use, the product is placed inside the limiting cylinder. When fixed, the air pump device outside the air pipe is used to pump air. At this time, the bottom of the product contacts the rubber disc, and the product can be effectively fixed under negative pressure. This setting does not require squeezing to fix the product, not only does it not cause damage to the product surface, but it is also very convenient to release.

[0019] After the product is taken out, the external air pump equipment is used to perform exhaust. At this time, the air is discharged from the placement plate and the rubber plate, which can clean the inside of the limit cylinder and discharge debris and impurities smoothly. The micro motor can drive the driving gear to rotate, and then the driven gear drives the hollow tube to rotate. The hollow tube can drive the placement plate and the rubber plate to rotate, so that the debris inside the limit cylinder is fully discharged, achieving the purpose of full cleaning.

[0020] When the hollow tube rotates, the sealing sleeve and the limit ring provided at the bottom of the hollow tube cooperate with each other to play a certain sealing role, ensuring that the air can smoothly pass through the fixed cylinder into the interior of the hollow tube.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figure 1 、 Figure 2 and Figure 3 , the utility model provides a technical solution:

[0029] A CNC multi-station rotary processing fixture, comprising a rotary table 1, a mounting plate 2 and a reinforcement plate 3.

[0030] The outside of the above-mentioned rotating table 1 is fixedly connected with evenly distributed mounting plates 2, and the tops of the above-mentioned mounting plates 2 are fixedly connected with support columns 6, and the tops of the support columns 6 are fixedly connected with positioning plates 4, and the inner sides of the above-mentioned positioning plates 4 are fixedly connected with limiting cylinders 5, and the bottoms of the above-mentioned limiting cylinders 5 are fixedly connected with fixing mechanisms 7, and the bottoms of the fixing mechanisms 7 are connected with air pipes 10, and the outsides of the above-mentioned air pipes 10 are provided with guide frames 8 and guide cylinders 9, and the tops of the guide frames 8 are fixedly connected to the mounting plates 2, and the bottoms of the above-mentioned guide frames 8 are fixedly connected to the guide cylinders 9;

[0031] The fixing mechanism 7 includes a fixing frame 701, a top cover 702, and a placement plate 703. The outer side of the fixing frame 701 is fixedly connected to the mounting plate 2, and the top of the fixing frame 701 is fixedly connected to the limiting cylinder 5. The interior of the fixing frame 701 is rotatably connected to a hollow tube 705, and a fixing cylinder 707 is installed at the bottom of the hollow tube 705. The outer side of the fixing cylinder 707 is fixedly connected to the fixing frame 701, and the bottom of the fixing cylinder 707 is connected to the air pipe 10.

[0032] The top of the hollow tube 705 is connected to a placement tray 703 .

[0033] The inner diameter of the top cover 702 is consistent with the inner diameter of the limiting cylinder 5 .

[0034] A rubber disc 704 is fixedly connected to the upper side of the placement disc 703 , and both the placement disc 703 and the rubber disc 704 are arranged in a disc shape.

[0035] At present, in order to ensure the processing efficiency, CNC machines on the market generally set up multiple stations when doing cutting processing. The products are installed on the stations, and the stations can be driven to move by a rotary table or some rotating mechanisms, thereby realizing the smooth processing of the products. Traditional products are generally fixed by squeezing and clamping the products during installation and fixing. There are the following problems in actual use: first, squeezing and clamping may cause scratches on the surface of the product, causing surface damage and affecting product quality. Secondly, after the product processing is completed, the debris generated is located on the surface or inside of the clamping mechanism, affecting the next use. The device is connected to an external power supply when in use, and the product is placed inside the limit cylinder 5. When fixed, it uses an air pump device on the outside of the air pipe 10 to perform an air pumping action. At this time, the bottom of the product is in contact with the rubber disc 704, and the product can be effectively fixed under negative pressure. This setting does not require squeezing to fix the product, not only will it not cause damage to the product surface, but it is also very convenient to release.

[0036] In this embodiment, an existing product air pump device is installed on one side of the air pipe 10, which can perform normal air intake and exhaust, and the guide frame 8 and the guide cylinder 9 can guide the air pipe 10 to prevent it from being entangled, and the inner diameter of the top cover 702 is consistent with the inner diameter of the limiting cylinder 5 to ensure that the product can be installed smoothly therein, and the placement plate 703 and the rubber plate 704 can ensure that it can rotate smoothly under the drive of the hollow tube 705.

[0037] Example 2: This example is an improvement on Example 1. Figure 3 、 Figure 4 and Figure 5 Specifically, ventilation holes are provided on the upper surfaces of the placement plate 703 and the rubber plate 704, and the ventilation holes of the placement plate 703 and the rubber plate 704 are arranged to overlap.

[0038] A micro motor 709 is fixedly connected to the interior of the fixed frame 701 , a driving gear 710 is fixedly connected to the end of the main shaft of the micro motor 709 , and a driven gear 711 is meshed with the outside of the driving gear 710 , and the inside of the driven gear 711 is fixedly connected to the hollow tube 705 .

[0039] A sealing sleeve 706 is fixedly connected to the outer side of the lower portion of the hollow tube 705 , and a limiting ring 708 fixedly connected to the fixing tube 707 is provided below the sealing sleeve 706 .

[0040] After the product is taken out, the external air pump device is used to perform exhaust. At this time, the air is discharged from the placement plate 703 and the rubber plate 704, which can clean the interior of the limiting cylinder 5 and discharge debris and impurities smoothly. The micro motor 709 can drive the driving gear 710 to rotate, and then the driven gear 711 drives the hollow tube 705 to rotate. The hollow tube 705 can drive the placement plate 703 and the rubber plate 704 to rotate, so that the debris inside the limiting cylinder 5 is fully discharged, achieving the purpose of sufficient cleaning. When the hollow tube 705 rotates, the sealing sleeve 706 and the limiting ring 708 provided at the bottom of the hollow tube 705 cooperate to play a certain sealing role, ensuring that the air can smoothly pass through the fixing tube 707 and enter the interior of the hollow tube 705.

[0041] In this embodiment, the vent holes of the placement plate 703 and the rubber plate 704 are arranged to overlap, which can ensure that the gas is discharged smoothly, or a negative pressure suction action can be performed. At the same time, the rubber plate 704 can play a certain buffering role, which can ensure that the product is in close contact with the rubber plate 704 and effectively fixed. The setting of the sealing sleeve 706 and the limiting ring 708 can fix the interior of the cylinder 707 in a maze-like distribution, effectively preventing air leakage and ensuring its sealing.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
