Description

Technical Field

[0001] The utility model relates to the technical field of auger blade processing, in particular to auger blade processing equipment. Background Art

[0002] The auger (screw) is mainly composed of a central shaft and blades welded on the central shaft. The blades are wound around the central shaft in a spiral line. It is the main part of various conveyors. It is widely used in agricultural machinery, grain machinery, feed machinery, chemical machinery, mining machinery, centrifugal separators and other equipment. For auger conveyors with high precision requirements, the outer circle of the auger blades must be processed.

[0003] For example, patent number CN 217290580 U discloses a processing device for the outer circle of an auger blade, including a CNC lathe and a rotary milling device, a connecting mechanism is installed between the rotary milling device and the CNC lathe, and the connecting mechanism is used to drive the rotary milling device to move along the length direction and width direction of the CNC lathe. The utility model adds a rotary milling device, and the processing tool can perform continuous and rapid cutting along the shape of the auger blade, changing the previous turning processing of the outer circle of the auger blade into milling processing, and the processing tool has no idle stroke, shortening the processing cycle, improving the processing efficiency by more than 10 times, and reducing the cutting force by about 50%, reducing the processing energy consumption.

[0004] When the device is grinding, the distance of each feed in the axial milling process is small, which requires a long processing time. In addition, since the structure is unidirectional, the outer circle of the blade needs to be processed reciprocally, and the tool needs to be re-aligned when processing the other side of the blade, which is inconvenient.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] See also Figure 1-7 A kind of auger blade processing equipment includes a machine tool 1, a slideway connected to a rodless cylinder 4 is symmetrically opened on the top of the machine tool 1, a pneumatic clamp 2 is rotatably installed on one side of the top of the machine tool 1, and an auger blade 3 is clamped in the pneumatic clamp 2, one of the rodless cylinders 4 is connected to a top plate 5 at the outer end, and the end of the top plate 5 is in another slideway, and a movable bin 6 is movably connected to the outer end of the rodless cylinder 4, and a groove is opened in the center of the outer side of the movable bin 6, and a hydraulic cylinder 7 is connected to the middle end of the groove wall, and the output end of the hydraulic cylinder 7 is connected to an "L The connecting plate 8 is bent inwardly into the "" shape, the end of the connecting plate 8 is connected with an adjusting disk 11, the end of the adjusting disk 11 is rotatably connected with a fixed disk 12, the end of the fixed disk 12 is connected with a transmission device 9, and the output end of the transmission device 9 is connected with a grinding device 10. Before processing, the auger blade 3 is first fixed inside the pneumatic clamp 2, and then the rodless cylinder 4 drives the top plate 5 to move to ensure that the side of the top plate 5 is supported, and then the pneumatic clamp 2 and the grinding device 10 are rotated for processing, wherein the machine tool 1 is a CNC machine tool.

[0030] The vertical height of the connecting plate 8 remains unchanged when connected, which can ensure that the grinding devices 10 corresponding to different types of auger blades 3 are always at the same height during processing, thereby adapting to the processing of auger blades 3 of different diameters. Since the torsion degrees of different auger blades 3 are different, in order to ensure that the grinding tool fits tangentially with them, it is necessary to adjust the processing angle, unscrew the bolts on the adjusting disk 11, and rotate the fixed disk 12 until the threaded hole on the fixed disk 12 corresponds to a threaded hole with a different deflection angle on the adjusting disk 11. After ensuring that the grinding device 10 is adjusted to the corresponding angle, tighten the bolts to complete the angle adjustment.

[0031] Since the thickness of the auger blade 3 of different signals is also different, before processing, the rodless cylinder 4 is started to make the movable bin 6 correspond to the auger blade 3, and then the motor 1 902 is started to drive the gear column 903 to rotate, drive the rack 1 904 and the rack 2 905 to retract inward, and start the hydraulic cylinder 7 at the same time to feed the knife. Driven by the motor 1 902, the rack 1 904 and the rack 2 905 move along the inner wall of the transmission bin 901, and then drive the connecting column 1 1002 to move, and drive the mounting plate 1004 to move along the outer end surface of the transmission bin 901 through the connecting column 2 1003, so that the two mounting plates 1004 are close to each other. When the grinding knife and the auger are close, the grinding knife and the auger are close to each other. When the blade 3 contacts, the transmission of motor 1 902 is stopped and the locking is completed. Then, motor 2 1005 and the external transmission equipment are started synchronously to drive the pneumatic clamp 2 to rotate, and cooperate with the controller of the machine tool 1 itself to drive the rodless cylinder 4 to synchronously transmit the mobile bin 6, thereby ensuring that the two grinding knives are in contact with the auger blade 3 during processing and move synchronously with the rodless cylinder 4, so that the two surfaces of the entire auger blade 3 are processed synchronously, and after one stroke, the motor 2 1005 and the rodless cylinder 4 are started in reverse and the pneumatic clamp 2 is rotated in reverse, and the accuracy is adjusted by motor 1 902, so that the auger blade 3 is processed for the second time, thereby ensuring work efficiency.

[0032] After the processing is completed, the motor 902 rotates in the opposite direction to drive the two racks to cooperate with the extension of the hydraulic cylinder 7 to complete the retraction of the tool, and the auger blade 3 can be removed.

[0033] Furthermore, when the motor 2 1005 is started, it will drive the grinding tool to rotate, and it is necessary to ensure that the two motors 2 1005 rotate in the same direction and in the opposite direction to the pneumatic clamp 2, which can ensure that the friction can be greatly increased during grinding, making the processing faster.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
