[0026] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments 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 creative work should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so as to describe the embodiments of the present invention described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0029] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0030] like Figures 1 to 4 As shown, the present invention provides a deburring tool, including: a workbench 1, a grinding device 2 and an adjustment structure. Among them, the grinding device 2 is arranged on the workbench 1, the adjustment structure is arranged on the workbench 1, and the adjustment structure can adjust the relative position of the claw pole and the workbench 1, so that the grinding device 2 can process all the areas to be ground on the claw pole. When in use, the claw pole is placed on the workbench 1, and the claw pole is continuously adjusted to its relative position on the workbench 1 (the relative position includes moving on the workbench 1 and rotating on the workbench 1) through the drive of the adjustment structure, so that the grinding device 2 can grind all the areas to be ground (areas with burrs) on the claw pole according to the preset running trajectory, and finally complete the deburring operation of the claw pole.

[0031] Specifically, the claw pole has a circular bottom plate and a plurality of claw rulers, all of which are distributed on the bottom plate in a ring shape with the axis of the circular bottom plate as the axis, wherein each claw ruler has burrs at the connection portion with the bottom plate, that is, each claw ruler forms an area to be polished at the connection portion with the bottom plate. When the claw pole is placed on the workbench 1, the adjustment structure can move all the areas to be polished on the claw pole to the processing position of the polishing device 2 by moving the position of the claw pole and rotating the claw pole, effectively overcoming the problems of high strength, low efficiency and poor quality in the prior art that the claw pole needs to be polished manually.

[0032] Furthermore, a fixing structure is provided on the workbench 1, and when the grinding device 2 processes the claw pole, the claw pole is fixed to the workbench 1 through the fixing structure. The fixing of the fixing structure can prevent the claw pole from moving relative to the grinding device 2 when the grinding device 2 processes the claw pole, thereby preventing the grinding effect of the grinding device 2 from being affected.

[0033] More specifically, the fixing structure includes a fixing plate 3, on which a mounting groove 31 is provided, and the claw pole is engaged with the mounting groove 31. After the moving structure moves the claw pole to the corresponding grinding device 2, the claw pole is placed in the mounting groove 31, and the mounting groove 31 is engaged with the claw pole to avoid relative movement between the claw pole and the workbench 1.

[0034] Optionally, the number of the mounting grooves 31 is the same as the number of claw rulers on the claw pole, and each claw ruler can be inserted into the mounting groove 31, thereby fixing the claw pole.

[0035] Furthermore, the adjustment structure includes a gripping mechanism 4, which is disposed on the workbench 1, and has a first state in which the claw pole is placed in the mounting groove 31 for clamping and a second state in which the claw pole is removed from the mounting groove 31. Driven by the gripping mechanism 4, the claw pole can be automatically fixed in the mounting groove 31 and removed from the mounting groove 31, thereby realizing the automation of the fixing of the claw pole.

[0036] In order to prevent the grabbing mechanism 4 from being above the adjustment structure and the grinding device 2 and affecting the normal operation of the grinding device 2, the present application provides an avoidance hole 32 on the fixed disk 3, and the grabbing mechanism 4 is arranged below the fixed disk 3, and the grabbing mechanism 4 can protrude from the fixed disk 3 through the avoidance hole 32. The claw pole is moved by the protrusion or escape of the grabbing mechanism 4 in the avoidance hole 32. In the process of switching to the first state, the grabbing mechanism 4 protrudes from the avoidance hole 32 to grab the claw pole, and then the grabbing mechanism 4 gradually retracts below the avoidance hole 32. At this time, the claw pole is driven by the grabbing mechanism 4 to move to the set position of the fixed structure, so that the claw pole is clamped and fixed with the mounting groove 31. When in the first state, the grinding device 2 starts to grind the corresponding position on the claw pole. In the process of switching from the first state to the second state, the grabbing mechanism 4 gradually extends above the avoidance hole 32, and at this time, the claw pole is driven to disengage from the mounting groove 31. Finally, in the second state, the claw pole is placed on the moving structure.

[0037] Preferably, the gripping mechanism 4 includes an airbag. In the first state, the airbag extends into the claw pole and abuts and fixes with the corresponding structure in the claw pole. In the second state, the airbag escapes from the claw pole. An inner hole for installing a rotating shaft is provided on the bottom plate of the claw pole. In the first state, after the airbag extends into the inner hole, the airbag begins to inflate and become larger until the airbag and the inner surface of the inner hole are squeezed and matched. At this time, the airbag completes the fixation of the claw pole, and the gripping mechanism 4 can drive the claw pole to move through the airbag. In the second state, the airbag deflates and becomes smaller, gradually detaching from the inner hole, completing the detachment of the airbag from the claw pole.

[0038] Among them, the gripping mechanism 4 also includes a push-pull rod, and the airbag is arranged on the push-pull rod. Before the airbag starts to inflate, the push-pull rod sends the airbag into the inner hole, and drives the airbag and the claw pole to move after the airbag is completely inflated. After the airbag is completely deflated, the push-pull rod pulls the airbag out of the inner hole to complete the separation of the airbag and the claw pole.

[0039] In order to facilitate the grinding process of the grinding device 2 on the areas to be ground at different positions of the claw pole, the adjustment structure also includes a rotating mechanism (not shown in the figure), which is arranged on the workbench 1, and the gripping mechanism 4 is arranged on the rotating mechanism, and the gripping mechanism 4 can be rotated under the drive of the rotating mechanism. By rotating and adjusting the relative position of the area to be ground on the claw pole on the workbench 1, after a region to be ground on the claw pole is finished being ground by the grinding device 2 and before the claw pole is fixed to the fixed structure, the rotating mechanism can drive the gripping mechanism 4 and the claw pole on the gripping mechanism 4 to rotate by a set angle at the same time, that is, the position of the un-grinded area to be ground and the finished area to be ground on the claw pole is changed, so that the un-grinded area to be ground is moved to the processing position of the grinding device 2 for processing.

[0040] For example, there are 8 evenly distributed areas to be polished on the claw pole, and the central angle formed by two adjacent areas to be polished is 45°. At this time, the rotating mechanism drives the claw pole to rotate 45° each time.

[0041] Due to the different shapes of the areas to be polished on the claw pole, the required running paths of the polishing device 2 are different, or the use of a single polishing device 2 for processing has the problem of too high replacement frequency of the polishing device 2. Therefore, the number of polishing devices 2 in the present application is at least two, and the adjustment structure includes a moving mechanism. All polishing devices 2 are arranged on the workbench 1. The moving mechanism is arranged on the workbench 1, and the moving mechanism is used to drive the claw pole to pass through all polishing devices 2 in sequence. By setting up multiple polishing devices 2, the replacement frequency of the polishing device 2 can be reduced, and different preset processing paths can also be set on each polishing device 2 to perform polishing processing on different areas to be polished of the claw pole.

[0042] Assuming that the preset processing paths of all grinding devices 2 are the same, the claw pole completes the grinding processing of an area to be polished at one grinding device 2. At this time, the moving mechanism can drive the claw pole to move to the next grinding device 2 to perform grinding processing on another area to be polished. In the process of the claw pole being moved by the moving mechanism, the position of the claw pole can be adjusted by the rotation of the rotating mechanism. Therefore, when two grinding devices 2 are installed on the workbench 1 in the same state, different areas to be polished of the claw pole can be polished.

[0043] More specifically, the mobile structure includes a conveyor belt 5, which is arranged on the workbench 1, and all the grinding devices 2 are evenly distributed on both sides of the conveyor belt 5, and the grinding devices 2 correspond to the areas to be ground on the claw poles one by one. When the grinding devices 2 are processing, the conveyor belt 5 is in a stopped state.

[0044] Furthermore, the grinding device 2 includes a grinding head, a horizontal motion mechanism and a lifting mechanism, wherein the horizontal motion mechanism is arranged on the workbench 1, the lifting mechanism is arranged on the horizontal motion mechanism, and the grinding head is arranged on the lifting mechanism. The multi-degree-of-freedom movement of the grinding head is realized by the horizontal motion mechanism and the lifting mechanism, so that the grinding head can perform grinding processing according to a preset path.

[0045] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0046] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0047] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
