Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Refer to Figure 1-7The diagram shows an automatic burr removal assembly for 7-axis machining of automotive parts, comprising an adapter plate 1, an adapter ring 2 on one side of the adapter plate 1, a grinding assembly body 6 fixedly installed inside the adapter ring 2, a positioning groove 21 fixedly connected to one side of the adapter ring 2, a positioning block 11 fixedly connected to one side of the adapter plate 1, the positioning block 11 being movably engaged inside the positioning groove 21, a positioning component 3 slidably connected to one side of the positioning groove 21, one end of the positioning component 3 movably penetrating inside the positioning block 11, and a locking device 4 rotatably connected to one side of the adapter plate 1. The positioning component 3 includes a first side plate 31 and several positioning rods 32, the several positioning rods 32 being fixedly connected to one side of the first side plate 31, several circular holes 111 being formed inside the positioning block 11, the positioning rods 32 movably penetrating inside the circular holes 111, one end of the positioning rods 32 having a positioning hole 321, and one end of the locking device 4 movably penetrating inside the positioning hole 321. Two positioning plates 12 are fixedly connected to one side of the adapter plate 1. The two ends of the locking device 4 are threadedly connected to the inside of the positioning plate 12. The locking device 4 includes a long rod 41, a threaded rod 42 and a rotating ring 43. The rotating ring 43 and the threaded rod 42 are fixedly connected to the two ends of the long rod 41. The long rod 41 has a thread on the outer side near the rotating ring 43. The long rod 41 is threadedly connected to the inside of one positioning plate 12, and the threaded rod 42 is threadedly connected to the inside of the other positioning plate 12. The grinding assembly body 6 includes a drive motor 61, a drive shaft 62, a grinding disc 63 and a mounting chamber 64. The drive end of the drive motor 61 is fixedly connected to one end of the drive shaft 62, and the other end of the drive shaft 62 is fixedly connected to the center of the grinding disc 63. The drive shaft 62 is located inside the mounting chamber 64, and the drive motor 61 is fixedly installed at one end of the mounting chamber 64. The inner side of the adapter ring 2 is fixedly connected to the outer side of the mounting chamber 64.

[0022] In this embodiment, during the installation of the grinding component body 6, the positioning block 11 of the adapter plate 1 is first snapped into the positioning groove 21; then the gripping extension pusher 33 drives the first side plate 31 and the positioning rod 32 to slide, so that the positioning rod 32 passes through the round hole 111 inside the positioning block 11 and extends out from the other side of the positioning groove 21, thereby completing the locking of the positioning component 3 to the positioning groove 21 and the positioning block 11; then the rotating ring 43 is gripped and the long rod 41 and the threaded rod 42 are rotated, so that the long rod 41 and the threaded rod 42 pass through the positioning hole 321, and one end of the threaded rod 42 is threaded to the inside of another positioning plate 12, thereby completing the locking operation of the locking device 4 on the positioning component 3.

[0024] The positioning and installation of the grinding component body 6 are all completed on one side, avoiding the risk of collision between the operator's hands and equipment parts in traditional confined spaces. At the same time, it reduces misoperations such as incorrect bolt installation and misalignment of positioning rods caused by obstructed vision and limited operation, thereby reducing the probability of damage during component installation and improving the safety and reliability of assembly operations. The snap-fit ​​engagement between the positioning block 11 and the positioning groove 21, and the guide structure of the positioning rod 32 passing through the circular hole 111, form a double positioning constraint, which can accurately control the relative position of the grinding component body 6 and the multi-axis drive end of the processing equipment, ensuring the coaxiality and flatness of the connection between the two, effectively avoiding problems such as grinding trajectory deviation and workpiece processing dimension deviation caused by installation deviation, and providing a basic guarantee for the accuracy and stability of subsequent grinding operations.

The positioning protrusion 332 is movably engaged in the rectangular groove 313. The four corners of the adapter plate 1 are respectively provided with mounting holes 13. Bolts movably pass through the mounting holes 13.

[0026] In this embodiment, after the sliding operation between the first side plate 31 and the positioning rod 32 is completed, the extension pusher 33 can be pushed laterally, causing the positioning protrusion 332 at one end of the extension pusher 33 to slide out from inside the rectangular groove 313, and then the extension pusher 33 can be removed. The detachable design of the extension pusher 33 can release the space redundancy of the grinding area and avoid the obstruction or restriction of the grinding path by traditional fixed auxiliary components. Especially for the grinding needs of automotive parts such as complex curved shells and deep cavity structural parts, it can ensure that the grinding head of the grinding component body 6 can accurately cover the workpiece edges, corners, grooves and other key areas, reduce grinding dead angles caused by spatial interference, and improve the integrity and consistency of the workpiece surface processing.

[0027] Example 3: According to Figure 1-6 As shown, the 7-axis automatic burr removal assembly for automotive parts in this invention includes an adapter plate 1. An adapter ring 2 is provided on one side of the adapter plate 1. A grinding assembly body 6 is fixedly installed inside the adapter ring 2. A positioning groove 21 is fixedly connected to one side of the adapter ring 2. A positioning block 11 is fixedly connected to one side of the adapter plate 1. The positioning block 11 is movably engaged inside the positioning groove 21. A positioning component 3 is slidably connected to one side of the positioning groove 21. One end of the positioning component 3 movably passes through the interior of the positioning block 11. A locking device 4 is rotatably connected to one side of the adapter plate 1. The positioning component 3 includes a first side plate 31 and several positioning rods 32. The several positioning rods 32 are fixedly connected to one side of the first side plate 31. Several circular holes 111 are opened inside the positioning block 11. The positioning rods 32 movably pass through the interior of the circular holes 111. One end of the positioning rod 32 has a positioning hole 321. The locking device 4... One end of the locking device 4 is movable through the interior of the positioning hole 321. Two positioning plates 12 are fixedly connected to one side of the adapter plate 1. The two ends of the locking device 4 are respectively threaded to the interior of the positioning plates 12. An isolation cover 5 is provided on the outside of the two positioning plates 12. One side of the isolation cover 5 is fixedly connected to one side of the adapter plate 1. The isolation cover 5 includes a second side plate 51 and a third baffle 52. One end of the second side plate 51 is fixedly connected to one end of the third baffle 52. The third baffle 52 is a transparent baffle and is made of acrylic sheet. The locking device 4 includes a long rod 41, a threaded rod 42 and a rotating ring 43. The rotating ring 43 and the threaded rod 42 are respectively fixedly connected to the two ends of the long rod 41. The long rod 41 is threaded on the outside of the end near the rotating ring 43. The end of the long rod 41 near the rotating ring 43 is threaded to the interior of one positioning plate 12, and the threaded rod 42 is threaded to the interior of the other positioning plate 12.

[0028] In this embodiment, when the operator rotates the locking device 4, the rotation status of the long rod 41 and the threaded rod 42 can be observed in real time through the third baffle 52, effectively avoiding the problems of excessive rotation or insufficient rotation, thereby ensuring the stability and reliability of the locking effect of the locking device 4 on the positioning component 3; in addition, the positioning component 3 can effectively protect the locking device 4 and reduce the impact of external environmental factors on the locking device 4.

This avoids damage to the thread profile and deformation of the threaded rod 42 or the threaded hole of the positioning plate 12 due to excessive rotation, and also prevents insufficient thread engagement depth due to insufficient rotation. This eliminates problems such as displacement of the positioning component 3 and shaking of the grinding component body 6 caused by loose locking during grinding operations, and provides precision guarantee for the long-term stability of the locking structure.

[0030] The usage and working principle of this device are as follows: During the installation of the main body 6 of the grinding component, the positioning block 11 of the adapter plate 1 is first snapped into the positioning groove 21; then, the gripping extension pusher 33 drives the first side plate 31 and the positioning rod 32 to slide, so that the positioning rod 32 passes through the round hole 111 inside the positioning block 11 and extends out from the other side of the positioning groove 21, thereby completing the locking of the positioning component 3 to the positioning groove 21 and the positioning block 11; then, the rotating ring 43 is gripped and the long rod 41 and the threaded rod 42 are rotated, so that the long rod 41 and the threaded rod 42 pass through the positioning hole 321, and one end of the threaded rod 42 is threaded to the inside of another positioning plate 12, thereby completing the locking operation of the locking device 4 to the positioning component 3. When the operator rotates the locking device 4, the rotation status of the long rod 41 and the threaded rod 42 can be observed in real time through the third baffle 52, effectively avoiding the problems of excessive rotation or insufficient rotation.

[0031] After the sliding operation between the first side plate 31 and the positioning rod 32 is completed, the extension pusher 33 can be pushed laterally so that the positioning protrusion 332 at one end of the extension pusher 33 slides out from the inside of the rectangular groove 313, and then the extension pusher 33 can be removed.

[0032] The drive motor 61 in the tube of the main body 6 of the grinding component drives the drive shaft 62 to rotate, and the drive shaft 62 drives the grinding disc 63 to perform surface processing on the surface of the automotive parts.
