[0027] Further, the rotary driving device comprises a rotary cylinder 3 installed on the rack, and the power output end of the rotary cylinder 3 is in transmission connection with one end of the product fixing rod 21. Specifically, the rotary cylinder 3 and the product fixing rod 21 are respectively installed on the two sides of the rack, one end of the product fixing rod 21 penetrates through the rack and is in transmission connection with the power output end of the rotary cylinder 3, the product fixing rod 21 is in rotary cooperation with the rack, and a bearing is installed between the product fixing rod 21 and the rack.

[0028] Further, the rotary limiting device comprises a limiting disc 4 fixedly installed on the product fixing rod 21, and the rack is provided with a fixed limiting assembly and a movable limiting assembly matched with the limiting disc 4; the movable limiting assembly comprises a limiting cylinder 51, and the power output end of the limiting cylinder 51 is installed with a movable limiting block 52.

[0029] The limiting disc 4 comprises a disc body 41, and the disc body 41 is provided with a limiting lug 42 matched with the fixed limiting assembly and the movable limiting assembly for limiting. The fixed limiting assembly comprises two end limiting blocks 53 respectively limiting the rotary stroke of both ends of the product fixing rod 21, and the fixed limiting assembly further comprises an auxiliary limiting block 54 limiting the movable limiting block 52. The auxiliary limiting block 54 is located outside the rotary radius of the limiting lug 42, the movable limiting block 52 abuts against the auxiliary limiting block 54, and the limiting end portion of the movable limiting block 52 is located within the rotary radius of the limiting lug 42.

[0030] Two end limit blocks 53 cooperate with the limit disc 4 to limit two end positions of the rotating stroke of the product fixing rod 21, i.e. to limit the start position and the end position of the rotating stroke of the product fixing rod 21, and each position corresponds to a processing station of the product 8; the auxiliary limit block 54 is located outside the rotating scanning range of the limit disc 4, i.e. the auxiliary limit block 54 does not directly limit the product fixing rod 21, and the auxiliary limit block 54 is used to limit the position of the movable limit block 52, which is used to limit an intermediate arbitrary position of the rotating stroke of the product fixing rod 21. Through the position and shape design of the auxiliary limit block 54 and the movable limit block 52, at least one intermediate limit point can be set in the rotating stroke of the product fixing rod 21, which corresponds to a processing station of the product 8, and the number of intermediate limit points can be determined according to the processing requirements of the product 8. For example, when the product 8 needs three processing stations, i.e. three limit points, in addition to the two processing stations limited by the two end limit blocks 53, only one intermediate limit point needs to be designed to limit the intermediate processing station; when the product 8 needs four processing stations, two intermediate limit points are needed to correspond to the positions of the intermediate two processing stations.

[0031] In the present embodiment, the product 8 has three processing stations, so only one intermediate limit point is provided, and the movable limit block 52 is of a T-shaped structure, including a limit seat connected with the power output end of the limit cylinder 51, and an interference protrusion extending to the limit disc 4 is arranged on the limit seat; the auxiliary limit block 54 is provided with two, which are located on the two sides of the interference protrusion. In the process of driving the movable limit block 52 to move to the limit disc 4 by the limit cylinder 51, the movable limit block 52 first contacts the auxiliary limit block 54, the interference protrusion extends from between the two auxiliary limit blocks 54, and the limit seat abuts against the auxiliary limit block 54 when the movable limit block 52 reaches the limit working position; the product fixing rod 21 is driven to rotate by the rotating cylinder 3, so as to drive the limit disc 4 to rotate, and when the limit protrusion 42 of the limit disc 4 abuts against the interference protrusion, the product 8 reaches the intermediate processing station.

[0032] Further, the clamping driving device comprises a clamping cylinder 61, and the power output end of the clamping cylinder 61 is in transmission connection with the clamping support assembly. A cylinder fixing plate 62 is installed on the rack, and the clamping cylinder 61 is fixedly installed on the cylinder fixing plate 62.

[0033] Further, the clamping support assembly comprises a bearing seat 63, a clamping block 64 is installed in the bearing seat 63, a rotating bearing 65 is installed between the clamping block 64 and the bearing seat 63, and the bearing seat 63 is in transmission connection with the clamping driving device; the clamping block 64 is provided with a clamping cavity 66 which is open at the end of the product fixing rod 21, and an avoiding opening 67 is arranged on the outer wall of the clamping cavity 66 to facilitate the connection with the end of the product fixing rod 21, so that the product fixing rod 21 can be placed at the entrance of the clamping cavity 66, and the product fixing rod 21 is convenient to disassemble and assemble.

[0034] The outer ring of the rotating bearing 65 is fixedly connected with the bearing seat 63, and the inner ring of the rotating bearing 65 is fixedly connected with the clamping block 64. After the product 8 is installed on the product fixing rod 21, when the product fixing rod 21 needs to be clamped, the plunger of the clamping cylinder 61 moves backward to drive the clamping support assembly to move backward, one end of the product fixing rod 21 is connected with the rotating driving device, the other end of the product fixing rod 21 is placed at the entrance of the clamping cavity 66 of the clamping block 64 through the avoiding opening 67, and then the clamping cylinder 61 is started. The plunger of the clamping cylinder 61 drives the clamping support assembly to move to the product fixing rod 21, and the space inside the clamping cavity 66 provides a depth space for the end of the product fixing rod 21. When the end of the clamping block 64 abuts against the product 8, the clamping cylinder 61 stops working, and the product 8 is clamped between the clamping block 64 and the product limiting boss 23 of the product fixing rod 21.

[0035] Further, the rack comprises a base 11, two vertical plates 12 are fixedly installed on the base 11, and the product fixing rod 21 is installed between the two vertical plates 12. The rotating driving device and the rotating limiting device are installed on one vertical plate 12 and are respectively installed on the two sides of the vertical plate 12, and the clamping device is installed on the other vertical plate 12. The rotating limiting device is preferably installed below the product fixing rod 21.

[0036] Working principle: the product 8 is placed on the product fixing rod 21 in sequence, and a certain number of products 8 can be placed in each string; the whole string of products 8 is clamped between the product limiting boss 23 and the clamping block 64; after the product 8 is placed, the clamping cylinder 61 is ejected to drive the rotating bearing 65 and the connecting block to move, so as to press the product 8 tightly, and the existence of the bearing ensures that the whole string of products 8 can rotate smoothly when the product 8 is pressed tightly; after the product 8 is pressed tightly, the product 8 is in the first processing station, that is, the limiting boss 42 of the limiting disc 4 is in the limiting position of the limiting groove 22 of the product fixing rod 21, and the product 8 is in the first processing station. Figure 4The end limit block 53 at the starting end on the middle left side is in close fit, and the dry ice deburring action is performed on the No. 1 processing station of the product 8; after the burrs at the No. 1 processing station are removed, the limit cylinder 51 drives the dynamic limit block 52 to be ejected, and then the rotating cylinder 3 drives the product 8 to rotate until the limit protrusion 42 of the limit plate 4 is in close contact with the interference protrusion of the dynamic limit block 52. At this time, the product 8 is in the No. 2 processing station, and then the burrs are removed from the No. 2 processing station of the product 8; after the burrs at the No. 2 processing station are removed, the limit cylinder 51 drives the dynamic limit block 52 to retract, and the rotating cylinder 3 drives the product 8 to continue to rotate to the next processing position until all positions are fully processed. The rotating cylinder 3 drives the product fixing rod 21 to rotate to the initial position, and the product 8 is removed. At this point, all processing actions are completed.

[0037] like Figures 1 to 5 As shown, the tooling solution uses a rotary cylinder 3 to drive the product 8 to rotate. When the product 8 rotates to the angle required for processing, the product 8 is fixed at a specific angle by adding a mechanical limit, and then the robot 7 deburrs the product 8 along a fixed trajectory. In this way, the product 8 is clamped once, that is, dry ice deburring processing at multiple angles is achieved.

[0038] This technical solution has the following advantages:

[0039] 1. The tooling structure is simple and practical. The product 8 is driven to rotate automatically by the rotating cylinder 3. For products 8 that need to be processed in multiple positions, one or more limiters are added, and the reciprocating motion of the robot 7 along the fixed track is cooperated to realize multi-station sequential processing of the product 8. There is no need to disassemble the product 8 multiple times, and multiple parts of the product 8 can be automatically processed with one clamping. No manual operation is required during the period, which improves the operating efficiency of the personnel; at the same time, with the sequential movement of the robot 7 along the fixed track, continuous automatic processing is realized, without the need for human intervention, reducing the generation of defective products, greatly improving the processing quality of the product 8, and improving the yield of the product 8.

[0040] 2. It has a wide range of applications. When replacing product 8, you only need to change the corresponding limit device. The angle adjustment is more flexible and has strong versatility.

[0041] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
