The coating head 105 accumulates the curing material stored in the storage box 102 through the conveyance of the hose and the hollow tube 104, so as to facilitate the one-time full coating of the inner hole of the workpiece. A movement groove is provided on the outer circumferential wall of the hollow tube 104, and a moving rod is slidably connected in the movement groove. An ear plate is provided on the adjustment frame 103, and a contact rod 106 is movably connected to the ear plate. A pad is provided at the left end of the contact rod 106. The setting of the pad increases the contact area between the workpiece and the workpiece when the workpiece is in extrusion contact with the workpiece during the coating operation, so as to avoid damaging the outer surface of the workpiece. A convex plate is fixedly connected to the right end of the contact rod 106, and a reset spring 2 located on the contact rod 106 is sleeved between the convex plate and the ear plate, and the top end of the moving rod is fixedly connected to the convex plate. The moving rod and the contact rod 106 cooperate with the reset spring 2, thereby driving the coating head 105 to rotate when coating the inner hole of the workpiece, thereby ensuring the uniformity of the coating of the curing material.

[0078] See also Figure 8 , Fig. 9 and Fig.11 In the embodiment of the present invention, the cleaning mechanism 11 includes a vacuum cleaner body 111 disposed on the bottom shell wall of the substrate 5. A three-way connector 112 is installed at the output end of the vacuum cleaner body 111, and a blocking member 113 for blocking is provided inside the three-way connector 112. The blocking member 113 is composed of a rod body, a blocking ball, an end cap and a reset spring, wherein the rod body, the blocking ball and the end cap are integrally arranged, the blocking ball is located inside the three-way connector 112, and the end cap is located at the other end of the rod body. The reset spring is set on the rod body, and then the blocking ball is driven by the movement of the rod body to block the ventilation pipe of the three-way connector 112. A force rod 114 is installed at the left end of the blocking member 113, and a ball is rollingly connected to the left end of the force rod 114, and the ball is in active contact with the special-shaped plate 445. An auxiliary frame is set on the force rod 114, and the auxiliary frame is fixed to the bottom shell wall of the substrate 5 by bolts, thereby ensuring the movement stability of the force rod 114.

[0079] A combined gas pipe 115 for gas delivery is commonly connected between the hollow cross bar 1 63 and the hollow cross bar 2 73. The combined gas pipe 115 is connected to the three-way connector 112 via a hose. The setting of the combined gas pipe 115 realizes synchronous gas control of the hollow cross bar 1 63 and the hollow cross bar 2 73.

[0080] The working principle of the present invention is: when the equipment performs grinding processing on the inner hole of the end face of the workpiece, each workpiece to be processed is first discharged in sequence into the storage bin 61 in the feeding mechanism 6. At this time, the bottom layer of the workpiece to be processed is located on the bottom inner wall of the storage bin 61.

[0081] After the pre-stored loading of the workpiece to be processed is completed, the switching mechanism 4 is turned on through the external controller body. The motor 431 of the driving member 43 in the switching mechanism 4 operates and the vacuum cleaner body 111 in the cleaning mechanism 11 operates. The operation of the motor 431 drives the rotating shaft to rotate clockwise. At this time, the half gear 1 432 and the half gear 2 433 located on the rotating shaft move synchronously. The half gear 2 433 contacts the transmission gear 82 in the transmission mechanism 8 during the rotation process, thereby driving the transmission shaft 81 and the movable rod 83 to rotate synchronously. During the activity process, the movable rod 83 drives the adjustment plate 93 in the integration mechanism 9 to move to the left through the movement of the guide rod 85 in the movable groove, compressing the reset spring 1 94. During the movement process, the adjustment plate 93 realizes the synchronous driving of the hollow cross rod 1 63 in the feeding mechanism 6 and the hollow cross rod 2 73 in the unloading mechanism 7 through the connecting plate 91, so that they are displaced.

[0082] During the movement, the hollow cross bar 1 63 drives the strong electromagnetic disk 1 64 to contact the workpiece to be processed in the storage bin 61, and the hollow cross bar 2 73 drives the strong electromagnetic disk 2 74 to move during the movement. The strong electromagnetic disk 1 64 and the strong electromagnetic disk 2 74 are energized to produce a strong magnetic effect when moving, and then the strong electromagnetic disk 1 64 realizes stable loading of the workpiece to be processed. After the workpiece to be processed is pushed out of the storage bin 61, its left end contacts the fixed fixture 443 of the corresponding station, and the corresponding fixed fixture 443 automatically clamps the workpiece to be processed. In this way, the loading of the workpiece to be processed is completed.

[0083] The adjusting plate 93 synchronously drives the connecting arm to move during the movement, and the strong spring in the connecting arm ensures the stability of the round rod 66 during the initial movement of the connecting arm. In the initial movement of the connecting arm, the protruding rod moves along the guide groove on the abutment plate 65, so that the abutment plate 65 can be quickly retracted, thereby pre-supporting and limiting the workpiece to be processed on the next side, so as to prevent it from directly sliding down due to lack of support after the workpiece to be processed on the bottom layer is loaded and causing damage.

[0084] During the operation of the vacuum cleaner body 111, the suction force generated by it is transmitted to the combined air pipe 115 through the three-way connector 112 and the hose, so that the hollow cross rod 1 63 and the hollow cross rod 2 73 have strong suction force at the same time. The hollow cross rod 1 63 not only adsorbs and cleans the dust and other substances adhering to the inner hole of the workpiece to be processed, but also negatively adsorbs the strong electromagnetic disk 1 64 when it contacts the workpiece to be processed, further improving the stability of the workpiece to be processed when loading.

[0085] When the protruding rod moves to the end of the guide groove, the connecting arm continues to move. At this time, the strong spring is compressed, and the round rod 66 shrinks into the receiving groove on the fixing frame 67, thereby ensuring that the adjustment plate 93 has a sufficient movement range.

[0086] After the rotating shaft drives the half gear 1 432 and the half gear 2 433 to rotate two-thirds of a circle, when it continues to rotate, the half gear 2 433 disengages from the meshing with the transmission gear 82 in the transmission mechanism 8. Then the reset spring 1 94 in the integration mechanism 9 performs a reset movement, at which time the adjustment plate 93 drives the connecting plate 91 to perform a reset movement through the screw rod 92. In this way, the reset movement of the feeding mechanism 6 and the unloading mechanism 7 is realized. When the feeding mechanism 6 is in the reset operation, the connecting arm on it is reset, and then each abutment plate 65 is reset, so that the workpiece to be processed limited thereon falls under the action of gravity, so as to facilitate the subsequent loading operation of the workpiece to be processed. When the strong electromagnetic disk 1 64 and the strong electromagnetic disk 2 74 complete the reset, the power is canceled, and at this time, it lacks the magnetic attraction effect.

[0087] After the rotating shaft completes two-thirds of the rotation, the half gear 1 432 meshes with the driven gear 441 during its continuous rotation, thereby driving the rotating shaft to move counterclockwise, thereby causing the carrier plate 442 to rotate counterclockwise. The contact distance between the half gear 1 432 and the driven gear 441 is one-third of the rotation, thereby causing the carrier plate 442 to move accordingly. After the carrier plate 442 is adjusted, the multiple stations set on it are switched and adjusted, and the station for loading is moved to the displacement for processing, while the other stations are switched in sequence.

[0088] During the rotation of the carrier plate 442, the shaped plate 445 on it contacts the force-bearing rod 114 in the cleaning mechanism 11 during the movement, and squeezes it, so as to drive the blocking member 113 to move, thereby realizing the intermittent blocking of the three-way connector 112, so that the combined air pipe 115 stops sucking air intermittently. At this time, if there is a processed workpiece in the unloading mechanism 7, the workpiece is unloaded, and the workpiece directly falls into the carrier 75 arranged below under the action of gravity. The carrier 75 below is displaced on the bottom plate 72 under the action of the electric push rod 76 and pushed out of the unloading channel 71. The carrier 75 drives the unloaded workpiece to move right. When the workpiece on the carrier 75 moves to a certain distance, the processed inner hole on the workpiece contacts the coating head 105 on the coating mechanism 10, and other parts of the workpiece contact the contact rod 106. Then, as the carrier 75 continues to move, the contact rod 106 moves, stretching the reset spring 2. During the movement of the contact rod 106, the moving rod connected thereto slides in the moving groove, thereby driving the hollow tube 104 to rotate, so that the coating head 105 rotates in the inner hole, thereby realizing the convenient coating of the maintenance material to the inner hole.

[0089] After the coating of the inner hole of the workpiece is completed, the electric push rod 76 performs a reset movement, driving the carrier 75 to reset and move, and then when the workpiece on the carrier 75 leaves the coating head 105, the coated workpiece is unloaded.

[0090] After the workstation is switched, when the loading mechanism 6 and the unloading mechanism 7 perform repetitive motions, the external controller drives and adjusts the sliding seat 2 and the grinding structure body 3 on the worktable 1, thereby achieving inner hole grinding of the workpiece at the processing station.

[0091] After the workpiece has completed the grinding process, it enters the unloading station under the operation of the switching mechanism 4, and then unloading is achieved under the action of the unloading mechanism 7.

[0092] The process repeats itself repeatedly, thereby realizing the automatic and continuous loading, processing, unloading, coating and unloading operations of the workpiece.

[0093] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
