Description

Technical Field

[0001] The present invention relates to the field of conveying technology, and in particular to an auger-type chip conveying device and method for machine tools. Background Art

[0002] The gap between the auger and the housing is a crucial element in screw conveyors, affecting both the conveying efficiency and the output flow rate. Therefore, when selecting the auger and setting the gap, it's important to determine the appropriate gap based on actual conditions and adjust it through repeated testing to ensure proper operation of the screw conveyor.

[0003] The publication number is CN207917920U. A auger-type chip removal device for machine tools has the following problems raised in its background technology: the existing auger-type chip removal device has poor processing effect on low-density chips generated by non-metallic parts processing and is prone to entanglement during the processing of longer strip chips, thereby damaging the equipment. It uses an auger-type chip removal, which has a simple structure, requires a small installation space, and is convenient for accurately collecting chips and making them fall into a U-shaped conveying pipe to prevent chips from splashing and polluting the environment. In addition, tooth-like protrusions are provided on the edge of the auger blades to reduce the entanglement between chips and equipment.

[0004] Based on the existing technology, the following problems exist: The size of the gap between the auger and the shell directly affects the operating efficiency and output flow of the screw conveyor. If the gap between the auger and the shell is too large, the material may be retained and cause the conveying to be stuck, reducing the efficiency of the conveying; if the gap is too small, it will increase the friction of the screw conveyor, consume a lot of power, and also affect the production efficiency. When the screw conveyor adjusts the gap between the auger and the shell, it is necessary to ensure the parallelism of the auger and the shell. The adjustment process is relatively cumbersome and it is not easy to grasp the parallelism after adjustment. After the adjustment is completed, it is not easy to block the moving trajectory of the rotating shaft, which leads to the leakage of materials during the subsequent conveying of materials. Referring to the above application documents, it is only convenient for materials to enter the screw conveyor and reduce the entanglement and splashing of chips. There is no mechanism for adjusting the distance between the auger and the shell, which has certain shortcomings. In order to solve the above problems, an auger-type chip conveying device and method for machine tools are proposed. Summary of the Invention

Space is left between the bottom inner wall of the mounting frame 91 and the bottom of the adjustment plate 92 for the threaded tube to move vertically.

[0026] During specific implementation, the staff rotates the first threaded rod 61 by a wrench or the like, and the first threaded rod 61 causes the first threaded rods 61 at both ends of the housing 1 to rotate synchronously through the transmission mechanism 62, thereby driving the threaded tube and the adjustment plate 92 to move vertically under the limit of the slide groove 93 and the slider, so as to adjust the height of the rotating shaft 11 and the auger blade 2, so as to adjust the distance between the auger blade 2 and the bottom inner wall of the housing 1, so as to facilitate the conveying of different materials, reduce material accumulation and improve conveying efficiency, etc., and facilitate adjustment according to the actual conveyed materials; The adjusting plate 92 is rotatably connected to the rotating shaft 11, so that the height of the auger blade 2 can be adjusted by adjusting the height of the adjusting plate 92.

[0027] See also Figure 8 、 Figure 10 and Figure 11 , the limiting component 5 includes: The base plate 51 is rotatably provided on the side wall of the first threaded rod 61 and is fixedly connected to the bottom of the mounting frame 91. A ratchet is rotatably provided on the top of the base plate 51, and the inner wall of the ratchet is fixedly sleeved on the side wall of the first threaded rod 61. The ratchet is located at the bottom of the transmission mechanism 62. A locking assembly 52 is provided on the top of the base plate 51 and is symmetrically arranged with the center point of the ratchet to cooperate with the ratchet to lock the rotation of the first threaded rod 61.

[0028] The locking assembly 52 includes: The sleeve plate 521 is rotatably mounted on the top of the base plate 51. A locking plate 522 is sleeved on the side of the sleeve plate 521 close to the ratchet. The side of the locking plate 522 close to the ratchet is bent inward to form a pawl structure 524 that cooperates with the ratchet. A spring is fixed to the inner side of the locking plate 522, and the side of the spring away from the locking plate 522 is fixedly connected to the top of the base plate 51. A groove for sleeved on the side of the sleeve plate 521 close to the ratchet is provided, and the longitudinal section of the side wall of the end of the locking plate 522 located in the groove is rectangular. The second threaded rod 523 is threadedly connected to the outer side of the sleeve plate 521, and the end of the second threaded rod 523 is rotatably connected to the outer side of the locking plate 522, so that when the second threaded rod 523 is rotated, the locking plate 522 is driven to move along the inner wall of the sleeve plate 521.

[0029] In a specific implementation, when adjusting the height of the adjustment plate 92 and the auger blade 2 by rotating the first threaded rod 61, the locking plate 522 is first separated from the ratchet to cancel the locking of the first threaded rod 61, and the first threaded rod 61 can be rotated; When the first threaded rod 61 is rotated, the locking plate 522 is released, so that the pawl structure 524 of the locking plate 522 engages with the ratchet under the action of the spring, thereby locking the ratchet and the first threaded rod 61. The symmetrically arranged locking assembly 52 facilitates locking the forward and reverse rotation of the ratchet to avoid the first threaded rod 61 from rotating incorrectly due to vibration or other reasons during the rotation of the auger blade 2, thereby avoiding affecting the stability of the height adjustment of the auger blade 2. The second threaded rod 523 is provided to drive the locking plate 522 to move along the inner wall of the sleeve plate 521 when the second threaded rod 523 is rotated to adjust the position of the pawl structure 524, thereby avoiding the situation where the pawl structure 524 cannot engage with the ratchet due to the degree of rotation of the first threaded rod 61, so as to facilitate the actual adjustment and use of the first threaded rod 61.

[0030] See also Figure 9 , the support assembly 4 includes: The cylinder 43 is fixed to the bottom of the mounting frame 91 for storing pressurized gas; The support rod 41 is fixed to the bottom of the adjustment plate 92 and is located on the outside of the threaded tube.

[0031] In specific implementation, after the adjustment is completed, the adjustment plate 92 drives the support rod 41 and the piston to squeeze the pressurized gas along the inner wall of the cylinder 43, thereby supporting the adjustment plate 92 through the reverse force to support the auger blade 2, thereby improving the stability of the auger blade 2 and avoiding the influence of the gap between the first threaded rod 61 and the threaded tube on the stability of the auger blade 2, further improving the stability of the auger blade 2, and thus improving the stability of the conveying; The side walls of the cylinder body 43 are provided with pipes and valves to facilitate filling high-pressure gas into the cylinder body 43, so as to support the piston block 42 and adjust the supporting force according to actual use. The pipes and valves on the outer wall of the cylinder body 43 are conventional technologies in this field and are existing technologies, so they will not be described here.

[0032] The diameter of the side wall of the piston block 42 is larger than the diameter of the side wall of the support rod 41, so that the piston block 42 and the cylinder body 43 are locked, thereby preventing the support rod 41 from separating from the cylinder body 43; The top of the cylinder body 43 and the top of the mounting frame 91 are both provided with through holes for sleeve mounting the support rod 41 .

[0034] During specific implementation, when the adjustment plate 92 moves, the identification block 82 is driven to move, so that the height of the rotating shaft 11 and the auger blade 2 can be judged by the position of the identification block 82 pointing to the scale plate 81, which is convenient for actual adjustment and use. In addition, by arranging identification components 8 at both ends of the outer shell 1, it is convenient to grasp the height of the two ends of the rotating shaft 11, so as to judge whether the rotating shaft 11 is parallel, so as to grasp the parallelism of the auger blade 2 and the outer shell 1.

[0035] For example 2, please refer to Figure 4 、 Figure 5 and Figure 6 The difference between this embodiment and the first embodiment is that the blocking component 10 includes: The movable through slot 103 is opened at both ends of the shell 1. The first baffle 102 is fixedly provided on the inner wall of the shell 1 and close to the movable through slot 103. The top of the first baffle 102 is located at the bottom of the rotating shaft 11 and is located at the bottom of the rotating shaft 11 at the lowest position.

The second baffle 101 and the adjustment plate 92 are fitted together on the side close to each other. The rotating shaft 11 passes through the second baffle 101, and the side wall of the rotating shaft 11 is rotatably connected to the side wall of the second baffle 101.

[0037] In a specific implementation, the movement of the adjustment plate 92 simultaneously drives the rotation shaft 11 and the second baffle 101 to move, so that while adjusting the height of the rotation shaft 11, the second baffle 101 moves along the inner wall of the movable slot 103, so that the second baffle 101 blocks the moving trajectory of the rotation shaft 11, thereby preventing debris and other materials from leaking out along the moving trajectory of the rotation shaft 11, i.e., the movable slot 103, without affecting the adjustment of the height of the rotation shaft 11; The first baffle 102 blocks the moving through slot 103 at the bottom of the rotating shaft 11 to prevent the second baffle 101 from leaving a gap when moving upward, thereby improving the effect of preventing material leakage.

After the adjustment is completed, the first threaded rod 61 is self-locked by the limiting assembly 5 to prevent it from affecting the stability of the auger blade 2 due to external forces, and the adjusting plate 92 is supported by the supporting assembly 4 to further improve the stability of the auger blade 2, thereby avoiding affecting the stability of conveying. The height of the auger blade 2 is grasped from both ends of the rotating shaft 11 by the marking assembly 8, thereby facilitating the grasping of whether the auger blade 2 is parallel, thereby avoiding affecting subsequent conveying use.
