[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will combine the accompanying drawings of the embodiments of the present utility model Figures 1-4 , and clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.

[0027] Such as Figures 1-4As shown: This embodiment provides a pneumatic tooling for machining automotive flanges, including a base 100 and a driving cylinder 101 disposed on the upper surface of the base 100. The driving cylinder 101 is fixed to the base 100 by welding. It is characterized in that: a clamping cylinder 102 is disposed on the upper surface of the driving cylinder 101, and the upper surface of the driving cylinder 101 provides fixation for the clamping cylinder 102 by welding. A clamping assembly is disposed inside the clamping cylinder 102. The clamping assembly includes a rotating disk 106 disposed inside the clamping cylinder 102. The rotating disk 106 can rotate inside the clamping cylinder 102. Three arc-shaped grooves 107 are disposed on the rotating disk 106. Clamping members 200 are disposed inside the arc-shaped grooves 107. The three arc-shaped grooves 107 can drive the clamping members 200 to move. A connecting portion is disposed inside the clamping cylinder 102 and the driving cylinder 101. The connecting portion is connected to the middle part of the rotating disk 106. The connecting portion provides partial support for the rotating disk 106 and can drive the rotating disk 106 to rotate at the same time. A rotating member is disposed inside the driving cylinder 101. The rotating member is fixedly disposed at the end of the connecting portion. The rotating member can drive the connecting portion to rotate. A cylinder 105 is fixedly disposed at the top inside the driving cylinder 101. A transmission member 400 is disposed inside the driving cylinder 101. The output end of the cylinder 105 is fixedly disposed with the transmission member 400. The transmission member 400 is in transmission with the rotating member. Under the action of the cylinder 105, the transmission member 400 is driven, so that the transmission member 400 drives the rotating member, and then because the rotating member drives the connecting portion to rotate, when the connecting portion drives the rotating disk 106 to rotate, the rotating disk 106 drives the clamping members 200, so that the clamping members 200 fix the flange, thus simplifying some operations for fixing the flange and improving the work efficiency of personnel;

[0028] First, place the flange on the upper surface of the driving cylinder 101. By the operation of the cylinder 105, the output shaft of the cylinder 105 drives the transmission member 400, so that the transmission member 400 drives the rotating member, and the rotating member drives the connecting portion to rotate. Indirectly, the connecting portion drives the arc-shaped grooves 107 on the rotating disk 106 to rotate, so that the clamping members 200 can quickly clamp the flange. Then drive the cylinder 105 again so that the cylinder 105 operates in reverse, so that the flange can be released, thus simplifying some operations for fixing the flange and improving the work efficiency of personnel.

[0029] The clamping member 200 is as Figure 2 shown

[0030] The clamping member 200 includes moving columns 201 disposed in three arc-shaped grooves 107. When the rotating disk 106 drives the three arc-shaped grooves 107 to rotate, the moving columns 201 in the arc-shaped grooves 107 move along the tracks in the arc-shaped grooves 107. Fixed blocks 204 are provided at both ends of the moving columns 201. The fixed blocks 204 are located on the outer arc surface of the rotating disk 106. The moving columns 201 are fixed to the fixed blocks 204 by welding, which serves to connect the moving columns 201 and the rotating disk 106 and ensures that the moving columns 201 do not disengage from the arc-shaped grooves 107 during movement. Fixed columns 202 are provided at the side ends of the fixed blocks 204. Three through holes are provided on the arc surface of the clamping cylinder 102. The fixed columns 202 all penetrate through the three through holes. The fixed columns 202 are fixed to the fixed blocks 204 by welding. The fixed columns 202 not only strengthen the connection between the fixed blocks 204 and the rotating disk 106, but also limit the radial movement of the fixed blocks 204 and the moving columns 201 by penetrating through the through holes of the clamping cylinder 102. Arc-shaped blocks 203 are provided at the ends of the fixed columns 202. The arc-shaped blocks 203 are used to fit the flange, so that the flange can be effectively fixed.

[0031] When the rotating disk 106 rotates, since both ends of the moving column 201 are connected to the rotating disk 106 and the clamping cylinder 102 through the fixed blocks 204 and the fixed columns 202, they can only move along the tracks of the arc-shaped grooves 107. As the rotating disk 106 rotates, the moving column 201 gradually approaches or moves away from the workpiece, thereby realizing the clamping or releasing of the workpiece.

[0032] The driving cylinder 101 is as Figure 1 shown.

[0033] The connecting portion includes a rotating rod 300 disposed between the tops of the driving cylinder 101 and the clamping cylinder 102. The rotating rod 300 penetrates through the middle of the rotating disk 106. The rotating rod 300 is fixedly arranged with the rotating disk 106. Thus, the rotating rod 300 is installed on the tops of the driving cylinder 101 and the clamping cylinder 102 through bearings, thereby providing the rotating function for the rotating disk 106.

[0034] The rotating rod 300 is as Figure 2 shown.

[0035] The rotating member includes a gear 500 disposed at the end of the rotating rod 300. One side of the gear 500 is fixed to the rotating rod 300 by welding, thereby facilitating the driving of the gear 500 by the transmission assembly.

[0036] The transmission member 400 is as Figure 2 shown.

[0037] The transmission member 400 includes a chute 401 disposed within the drive cylinder 101. The chute 401 is fixed to the fixed wall within the drive cylinder 101 by welding. A sliding block 402 is slidably disposed within the chute 401 and can move within the chute 401. A rack plate 403 is provided at the end of the sliding block 402. The sliding block 402 within the chute 401 provides a guiding function for the rack plate 403. The side end of the rack plate 403 is fixedly provided with the output end of the air cylinder 105. The rack plate 403 is meshed with the gear 500. The movement of the rack plate 403 provides a driving function for the gear 500;

[0038] The mounting opening 104 is as Figure 1 shown.

[0039] A plurality of mounting openings 104 are provided on the base 100, and the mounting openings 104 facilitate the fixing of the base 100 on the mounting table;

[0040] The connecting door 103 is as Figure 1 shown.

[0041] A connecting door 103 is hingedly provided on the outer arc surface of the drive cylinder 101. When in use, by opening the connecting door 103, the intake pipe and the exhaust pipe can be inserted onto the air cylinder 105;

[0042] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly defined and limited, the terms "mounted", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0043] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
