DETAILED DESCRIPTION

[0029] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figures 1 to 5 As shown, a quick clamping device for mechanical manufacturing includes a driving frame 1, a transmission frame 2 and a working frame 3; one end of the transmission frame 2 is connected to the driving frame 1, and the transmission frame 2 is provided with a through hole that matches the driving frame 1; the working frame 3 is arranged at the end of the transmission frame 2 away from the driving frame 1, and the working frame 3 is provided with a through hole that matches the transmission frame 2; a driving component 11 is arranged in the driving frame 1, and the output end of the driving component 11 extends toward one end, and a fixing portion 12 is arranged on the top of the driving frame 1, and the fixing portion 12 is transmission-connected with the driving component 11; a transmission component 21 is arranged in the transmission frame 2, and one end of the transmission component 21 is connected to the driving component 11, and the end of the transmission component 21 away from the driving component 11 extends to the inside of the working frame 3; a rotating component 31 is arranged in the working frame 3, and one end of the rotating component 31 is transmission-connected with the transmission component 21, and a clamping claw 32 is arranged at the end of the rotating component 31 away from the transmission component 21.

[0031] When it is necessary to clamp the workpiece to be processed for inspection, the staff drives the fixed part 12 to rotate, and drives the driving component 11 to work through the fixed part 12, so that the driving component 11 can drive the transmission component 21 to work, and drive the rotating component 31 to rotate through the transmission component 21, so that the rotating component 31 can drive the clamping jaw 32 to clamp. After the workpiece to be processed is clamped, the staff can fix the driving component 11, the transmission component 21 and the rotating component 31 through the fixed part 12, so that the staff does not need to apply rotational force to the fixed part 12 when checking the workpiece to be processed. Through the arrangement of the driving component 11, the transmission component 21 and the rotating component 31, when the staff needs to check the workpiece to be processed, the driving component 11 can transmit the force to the transmission component 21, and the transmission component 21 can drive the rotating component 31 to rotate, so that the clamping jaw 32 can clamp, and at the same time, the fixed part 12 can fix the clamping jaw 32, so that the staff does not need to continue to apply rotational force to the fixed part 12 when checking the workpiece to be processed.

[0032] Reference Figure 3 As shown, the driving assembly 11 includes a rotating rod 111; the rotating rod 111 is arranged on the driving frame 1, one end of the rotating rod 111 is provided with a fixing portion 12, the driving frame 1 is provided with a through hole for the rotating rod 111 to pass through, the rotating rod 111 is provided with a rotating block 1111, and the end of the rotating rod 111 away from the fixing portion 12 is provided with a connecting rod 112, and the connecting rod 112 is provided with a rotating groove 1121 that cooperates with the rotating block 1111, the rotating rod 111 can move up and down in the rotating groove 1121, and the end of the connecting rod 112 away from the rotating rod 111 is connected to the transmission assembly 21.

[0033] When the driving assembly 11 needs to be driven, the staff drives the rotating rod 111 to rotate, and the rotating block 1111 starts to rotate at the same time through the rotating rod 111. The cooperation between the through hole rotating block 1111 and the rotating groove 1121 enables the connecting rod 112 to start rotating at the same time as the rotating rod 111 rotates, so that the connecting rod 112 can drive the transmission assembly 21.

[0034] Reference Figure 3 As shown, the fixing portion 12 includes a knob 121 , a protrusion 1211 is provided on the knob 121 , and a fixing seat 122 matching with the knob 121 and the protrusion 1211 is provided on the driving frame 1 .

[0035] When the staff needs to drive the rotating rod 111 to rotate, the rotating rod 111 can be driven to rotate by rotating the knob 121. At the same time, when the clamp 32 clamps the workpiece to be processed, the staff can press the knob 121 down, so that the knob 121 is fixed in the fixed seat 122 through the cooperation of the protrusion 1211 and the fixed seat 122, and the clamp 32 is fixed, so that the staff does not need to apply rotational force to the knob 121 when they need to check the workpiece to be processed.

[0036] Reference Figure 4 and Figure 5 As shown, the transmission assembly 21 includes a driving pulley 211; the driving pulley 211 is arranged at the bottom of the connecting rod 112, the driving pulley 211 is connected to the connecting rod 112, a driven pulley 212 is arranged in the transmission frame 2, a synchronous belt 213 is sleeved on the driving pulley 211 and the driven pulley 212, a driving gear 214 is arranged below the driven pulley 212, one end of the driving gear 214 is connected to the driven pulley 212, a driven gear 215 meshed with the driving gear 214 is arranged on one side of the driving gear 214, a rack 216 cooperating with the driving gear 214 and the driven gear 215 is respectively arranged on one side of the driving gear 214 and the driven gear 215, a moving frame 217 is arranged at the end of the rack 216 away from the driving frame 1, a hinged rod 2171 is arranged at the end of the moving frame 217 away from the rack 216, and the hinged rod 2171 is connected to the rotating assembly 31.

[0037] When the connecting rod 112 rotates, the driving pulley 211 rotates simultaneously with the rotation of the connecting rod 112. Through the setting of the synchronous belt 213, the driven pulley 212 starts to rotate simultaneously with the rotation of the driving pulley 211. When the driven pulley 212 rotates, the driving gear 214 starts to rotate at the same time. At the same time, through the meshing of the driving gear 214 and the driven gear 215, the driven gear 215 rotates simultaneously with the rotation of the driving gear 214. When the driving gear 214 and the driven gear 215 rotate, through the meshing of the driving gear 214 and the driven gear 215 with their corresponding rack 216, the rack 216 moves toward the direction of the driving frame 1 as the driving gear 214 and the driven gear 215 rotate. The rack 216 moves and drives the moving frame 217 to start moving at the same time. The moving frame 217 moves and drives the articulated rod 2171 to move at the same time.

[0038] Reference Figure 4 As shown, the end of the driving pulley 211 away from the connecting rod 112 and the end of the driven pulley 212 away from the gear are respectively provided with a first limiting rod 2111, and the first limiting rod 2111 is respectively connected to the inside of the driving frame 1 and the inside of the transmission frame 2, and the bottom of the driving gear 214 and the two ends of the driven gear 215 are respectively provided with a second limiting rod 2141, and the second limiting rod 2141 is connected to the inside of the transmission frame 2.

[0039] By setting the first limiting rod 2111 and the second limiting rod 2141, the driving pulley 211, the driven pulley 212, the driving gear 214 and the driven gear 215 are more stable during operation, ensuring that the driving pulley 211, the driven pulley 212, the driving gear 214 and the driven gear 215 will not deviate during operation, thereby improving the stability of operation.

[0040] Reference Figure 4 As shown, a moving rod 2161 is provided at one end of the rack 216 away from the moving frame 217, and the moving rod 2161 extends to the outside of the transmission frame 2. A spring 2162 is sleeved on the moving rod 2161, and one end of the spring 2162 is abutted against the rack 216, and the end of the spring 2162 away from the rack 216 is abutted against the inside of the transmission frame 2.

[0041] By setting the moving rod 2161, the rack 216 will not be offset when moving, thereby ensuring the stability of the rack 216. At the same time, by setting the spring 2162, when the rack 216 moves toward the driving frame 1, the spring 2162 is compressed, and the clamping claw 32 clamps the workpiece to be processed. When the clamping is completed, the rack 216 can be reset by the setting of the spring 2162, without the need for manual reset, thereby improving work efficiency.

[0042] Reference Figure 4 and Figure 5 As shown, the rotating assembly 31 includes a rotating frame 311; a rotating ring 312 is provided at one end of the rotating frame 311 away from the transmission frame 2, a fixed rod 313 rotatably connected to the rotating ring 312 is provided in the rotating ring 312, the fixed rod 313 is connected to the inside of the working frame 3, a clamping rod 314 is provided at one end of the rotating ring 312 away from the rotating frame 311, the end of the clamping rod 314 away from the rotating ring 312 is connected to the clamping claw 32, a fixing ring 315 is provided at the upper and lower ends of the rotating ring 312, the fixing ring 315 is connected to the fixing rod 313, a sliding block 3112 is provided at one end of the rotating frame 311, a sliding groove 3111 cooperating with the sliding block 3112 is provided in the rotating frame 311, an articulated seat 3113 is provided at one end of the sliding groove 3111, and the articulated seat 3113 is connected to the articulated rod 2171.

[0043] When the rack 216 moves toward the driving frame 1, the moving frame 217 moves at the same time, and the movement of the moving frame 217 drives the hinged rod 2171 to move at the same time. Through the cooperation of the hinged rod 2171 and the hinged seat 3113, the slider 3112 moves upward with the movement of the moving frame 217, so that the slider 3112 can slide in the slide groove 3111. When the slider 3112 moves, the rotating frame 311 starts to rotate with the movement of the slider 3112. The rotation of the rotating frame 311 drives the rotating ring 312 to rotate at the same time, and the clamping rod 314 starts to rotate at the same time through the rotating ring 312. The clamping jaw 32 is driven to move through the clamping rod 314, so that the clamping jaw 32 can clamp the workpiece to be processed.

[0044] Reference Figure 2 As shown, an anti-slip pad 321 is provided on the working end of the clamping jaw 32 .
