Technical Field

[0001] The utility model relates to the technical field of weld processing, in particular to a weld grinding device. Background Art

[0002] Friction stir welding is a process in which a cylindrical or other shaped stirring needle is inserted into the joint of the workpiece. The high-speed rotation of the welding head causes it to rub against the welding workpiece material, thereby raising the temperature of the material at the connection point and softening it to complete the welding. At the same time, the edge of the workpiece weld adheres to the stirring tool, forming burrs.

[0003] Aluminum alloy friction stir welding is a common welding method, which is widely used in the manufacture of lightweight structural parts in the fields of aviation, aerospace, and automobiles. However, aluminum alloy friction stir welding will produce burrs and spatters during the welding process, which will affect the surface quality and aesthetics of the weld.

[0004] Traditional deburring methods are mostly manual operations, which are inefficient and difficult to ensure quality. With the development of mechanical automation, the existing technology uses a mechanical arm to drive a grinding head to grind and remove burrs on the weld. However, the existing grinding equipment has certain problems in the process of removing burrs:

[0005] 1. The efficiency of product loading and unloading is low because the product transportation equipment and grinding equipment are not on the same production line. Therefore, the product needs to be transferred to the grinding equipment.

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0040] Reference Figure 1 As shown, the utility model discloses a weld grinding device, comprising: a bearing mechanism 1, a transfer mechanism 2 and a grinding mechanism 3, wherein: the bearing mechanism 1 is used to support and fix the product to be ground, and the transfer mechanism 2 cooperates with the bearing mechanism 1. After the product to be ground is placed on the bearing mechanism 1, the transfer mechanism 2 drives the product to be ground to move to the grinding mechanism 3 until it works, and finally the grinding process of the product to be ground is completed by the grinding mechanism 3, so that the product is ground and the burrs on the weld are removed.

[0041] Reference Figure 2 As shown, in this embodiment, the supporting mechanism 1 includes a tray 11, and the tray 11 is provided with a supporting positioning component and a clamping component. The supporting positioning component positions and supports the product, and the clamping component clamps and fixes the tray 11 and the product. When grinding and deburring, the position of the product is fixed to prevent the product from moving, thereby improving the grinding accuracy.

[0042] Specifically, the support and positioning assembly includes: two elastic positioning pins 12, an anti-mistake pin 13 and multiple support columns. Pin holes that cooperate with the elastic positioning pins 12 and the anti-mistake pin 13 are arranged on the product. The product is placed on multiple support columns 14, and the elastic positioning pins 12 and the anti-mistake pins 13 are respectively inserted into the pin holes to position the product. Among them: the placement position of the product can be determined by the two elastic positioning pins 12 to prevent the product from moving. However, some processed products are centrally symmetrical. When the two elastic positioning pins 12 are inserted into the corresponding pin holes, the placement position of the product may be reversed. Therefore, the anti-mistake pin 13 is also provided. In this way, the unique position of the product can be determined by three pins. The anti-mistake pin 13 is actually an anti-mistake measure.

[0043] Specifically, the clamping assembly includes: an automatic clamping assembly 15 and a manual clamping assembly 16. The automatic clamping assembly 15 clamps and fixes the product. The automatic clamping assembly 15 is arranged on the tray 11. The automatic clamping assembly 15 includes a rotating cylinder and a clamping block driven by the rotating cylinder. In the process of placing the product on the tray 11, the rotating cylinder drives the clamping block to avoid the reserved placement space. After the product is placed on the tray 11, the rotating cylinder drives the clamping block to move above the product, and the clamping block presses and clamps the product; the manual clamping assembly 16 clamps and fixes the tray 11 to limit the moving position of the tray 11.

[0044] In this embodiment, a sealing component 17 is also provided on the tray 11. The sealing component 17 is set corresponding to the processing hole on the product. After the product is placed on the tray 11, the sealing component 17 can cover the processing hole to prevent dust and waste chips after grinding from entering the processing hole and affecting the subsequent processing technology.

[0045] Reference Figure 3As shown, the blocking assembly 17 includes: a base 171, a sleeve 172, a plug 173, an elastic member 174 and a stopper bolt 175, wherein: the base 171 is arranged on the tray 11 and extends in a direction perpendicular to the tray 11, the sleeve 172 is slidably sleeved outside the base 171 along the extension direction of the base 171, the elastic member 174 is arranged between the base 171 and the sleeve 172, and is used to elastically support the sleeve 172. When no external force is applied, the elastic member 174 supports the sleeve 172, and when an external force is applied, the sleeve 172 can slide relative to the base 171. The plug 173 is arranged on the top of the sleeve 172. The size and shape of the plug 173 are the same as the size and shape of the processing hole of the product. The product is placed on the tray 11, and the plug 173 can be inserted into the processing hole of the product and completely block the processing hole. The limit bolt 175 is slidingly arranged in the base 171. The end of the limit bolt 175 protrudes from the base 171 and is connected to the sleeve 172. The sliding direction of the sleeve 172 relative to the base 171 can be limited by the limit bolt 175, thereby ensuring that the sleeve 172 will not tilt or deviate, and ensuring that the plug 173 can be inserted into the processing hole of the product.

[0046] In this embodiment, a sensor assembly 18 is also provided on the tray 11. The sensor assembly 18 is a proximity sensor for detecting the presence of a product. Only after a product is detected on the tray 11, the clamping assembly will clamp and fix the product, and the transfer mechanism 2 will drive the carrying mechanism 1 to move.

[0047] Reference Figure 4 As shown, the transfer mechanism 2 is arranged below the supporting mechanism 1, and the transfer mechanism 2 drives the pallet 11 to move back and forth in a directional manner. In this embodiment, the transfer mechanism 2 includes: a linear guide rail 21 and a driving source 22. The pallet 11 is placed on the linear guide rail 21 through a slider, and the pallet 11 is supported by the linear guide rail 21, and the pallet 11 is driven to slide along the linear guide rail 21 by the slider. The driving source 22 provides driving force for the pallet 11, and drives the pallet 11 to slide back and forth along the extension direction of the linear guide rail 21, thereby realizing rapid loading and unloading of products.

[0048] Specifically, in this embodiment, the product needs to be polished. The dust and waste generated during the polishing can easily enter the linear guide rail 21, thereby affecting the sliding of the tray 11 on the linear guide rail 21. Therefore, the linear guide rail needs to be sealed. The transfer mechanism 2 also includes an accordion cover 23, which is arranged outside the linear guide rail 21. The accordion cover 23 is connected to the pallet 11. When the pallet 11 moves, it can drive the accordion cover 23 to shrink and expand, thereby protecting the linear guide rail 21 without affecting the movement of the pallet 11.

[0049] Specifically, in the embodiment, in order to improve the working efficiency of the equipment, two groups of transfer mechanisms 2 are set, and each group of the transfer mechanisms 2 is provided with a carrying mechanism 1. The two groups of the transfer mechanisms 2 respectively complete the loading and unloading actions, and can achieve rhythm coordination with the grinding mechanism 3, thereby improving the equipment utilization rate, thereby increasing the output and achieving the purpose of reducing costs and increasing efficiency.

[0050] Reference Figure 5 As shown, the grinding mechanism 3 includes a grinding robot arm 31 and a grinding tool 32 driven by the grinding robot arm 31, the transfer mechanism 2 drives the tray 11 to move under the grinding tool 32, the grinding robot arm 31 drives the grinding tool 32 to grind along the weld on the product, and the grinding robot arm 31 is a multi-axis rotating robot arm, which can adjust the position, angle and working posture of the grinding tool 32 in real time according to the position of the weld on the product.

[0051] Specifically, the grinding tool 32 includes a grinding head and a blowing air knife 33. The grinding head is in contact with the weld. The grinding head is a hydraulically controlled adaptive force-controlled grinding head, which can achieve efficient and precise floating force-controlled stable deburring. The blowing air knife 33 provides compressed gas in the direction of the grinding head, which can blow the dust and waste generated by grinding off the product to prevent it from falling on the product and affecting subsequent processing technology.

[0052] In one embodiment of the utility model, the grinding mechanism 3 also includes: a tool changing magazine 34, in which the grinding head in the grinding tool 32 can be replaced. The tool changing magazine 34 is a 6-position mechanical tool changer, which can realize automatic tool changing when combined with a robot and can be suitable for grinding different forms of welds.

[0053] Reference Figure 1As shown, in order to better collect the dust and waste chips generated by grinding, the weld grinding equipment of this embodiment also includes: a profile frame 4, the supporting mechanism 1, the transfer mechanism 2 and the grinding mechanism 3 are all arranged in the profile frame 4, and a dust removal system 5 is also arranged in the profile frame 4, which is used to absorb the dust in the profile frame 4. After the dust removal system 5 collects the dust, it is discharged after dust removal treatment through the filter element, which can effectively control the leakage of dust and improve the production environment.

[0054] Specifically, the profile frame 4 is provided with an opening at a position corresponding to the transfer mechanism 2, and a safety grating 6 is provided at the opening. When the grinding equipment is working, the safety grating 6 is opened. When a staff member mistakenly enters the profile frame 4, the safety grating 6 can detect the entry of a person, and the grinding equipment will be stopped immediately to prevent damage to the personnel.

[0055] In addition, a code reader 7 is provided at the opening position of the profile frame 4 corresponding to the transfer mechanism 2, which can identify and detect the products entering and leaving, thereby determining the product information.

[0056] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
