Description

Technical Field

[0001] The utility model relates to the technical field of fitter processing, and specifically relates to a clamping tooling for fitter processing. Background Technique

[0002] Fitter processing refers to a process of performing a series of technological operations such as cutting, welding, grinding, and forming on materials such as metals and plastics by using fitter tools and equipment. During this process, a clamping tooling is used to clamp and fix the workpiece.

[0003] During the use of some existing clamping toolings for fitter processing, when adjusting the processing angle of the workpiece, it is necessary to disassemble and re-clamp and fix the workpiece, which is time-consuming and laborious, and thus is likely to have a certain impact on the processing efficiency of the workpiece.

[0004] Chinese Patent with the application number 202222502714.5 discloses a clamping tooling for fitter processing. By setting a rotating mechanism, the effect of adjusting the angle of the workbench is achieved. By setting a fixing mechanism, the effect of clamping and fixing workpieces of different sizes is achieved. By setting an adjusting mechanism, the effect of adjusting the angle of the workpiece is achieved.

[0005] The above patent solves the existing technical problems. However, when adjusting the angle of the workpiece, it is necessary to first start the air cylinder to release the limit state of the rotating shaft. After the rotating shaft rotates, start the air cylinder again to fix the position of the rotated rotating shaft. During this process, the operation is time-consuming, resulting in inconvenient angle adjustment of the workpiece. And when clamping the workpiece through the connecting plate, since the connecting plate can move on the sliding rod, when the workpiece is clamped and fixed, the sliding rods are on both sides of the workpiece, which makes it difficult to effectively process the outer surface of the workpiece close to the sliding rod. Therefore, we propose a clamping tooling for fitter processing. Content of the Utility Model

[0042] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in Figure 5 , the flipping mechanism 6 includes a first bevel gear 61 arranged on the upper surface of the mounting plate 1. Two one-way bevel gears 62 are meshed and connected to the outer surface of the first bevel gear 61. A worm 63 is arranged on the end face of the one-way bevel gear 62.

Two slide bars 74 are arranged on the upper surface of the slide plate 73, and the two slide bars 74 are slidably connected to the support frame 4. A support plate 75 is arranged at the upper ends of the two slide bars 74.

[0045] Specifically, as Figure 1 and Figure 4As shown, a protective cover 8 is provided on the lower surface of the support plate 75. The protective cover 8 is in contact with the first rotating plate 2. Through the protective cover 8, the main gear 653, the fixed gear 654, and the one-way gear 72 can be protected.

[0046] Working principle: During use, start the motor 651. The output end of the motor 651 rotates in reverse to drive the rotating shaft 652 to rotate in reverse. Then, the rotating shaft 652 rotates in reverse to drive the main gear 653 to rotate in reverse, thereby driving the fixed gear 654 to rotate in reverse and the one-way gear 72 to rotate. Then, the one-way gear 72 rotates to drive the reciprocating lead screw 71 to rotate, thereby driving the slide plate 73 to move upward. Then, the slide plate 73 moves upward to drive the slide rod 74 to move upward, thereby driving the support plate 75 to move upward to the highest position. At the same time, the fixed gear 654 rotates in reverse to drive the first rotating plate 2 to rotate in reverse. Then, the first rotating plate 2 rotates in reverse to drive the fixed plate 3, the second rotating plate 51, the cylinder 52, the clamping plate 53, the limit telescopic rod 54, the one-way bevel gear 62, the worm 63, and the worm gear 64 to rotate in reverse with the center of the first rotating plate 2 as the center. During this process, the one-way bevel gear 62 is in a non-rotating state and will not drive the worm 63 to rotate;

[0047] After the support plate 75 moves upward to the highest position, place the rectangular workpiece on the support plate 75. Then start the cylinder 52. The output end of the cylinder 52 extends to drive the clamping plate 53 to move, and clamps and fixes the rectangular workpiece on the support plate 75. During this process, through the setting of the limit telescopic rod 54, the clamping plate 53 is limited, so that the clamping plate 53 moves stably;

[0048] After the rectangular workpiece is clamped and fixed, start the motor 651. The output end of the motor 651 rotates in reverse to drive the rotating shaft 652 to rotate in reverse, causing the one-way gear 72 to rotate. Then, the one-way gear 72 rotates to drive the reciprocating lead screw 71 to rotate, so that the support plate 75 moves downward to the lowest position. At this time, the clamped and fixed rectangular workpiece can be processed;

[0049] After one side surface of the rectangular workpiece is processed, the motor 651 is started. The output end of the motor 651 rotates forward to drive the rotating shaft 652 to rotate forward. Then, the main gear 653 is driven to rotate forward by the forward rotation of the rotating shaft 652, and further drives the fixed gear 654 to rotate forward. Then, the rotating plate one 2 is driven to rotate forward by the forward rotation of the fixed gear 654, and further drives the fixed plate 3, the rotating plate two 51, the air cylinder 52, the clamping plate 53, the limit telescopic rod 54, the one-way bevel gear 62, the worm 63 and the worm gear 64 to rotate forward with the center of the rotating plate one 2 as the center. Because the one-way bevel gear 62 is meshed and connected with the bevel gear one 61, the one-way bevel gear 62 rotates self while rotating forward. Then, the worm 63 is driven to rotate by the self-rotation of the one-way bevel gear 62, and further drives the worm gear 64 to rotate. Then, the rotating plate two 51, the air cylinder 52, the clamping plate 53 and the limit telescopic rod 54 are driven to rotate by the rotation of the worm gear 64, so that the clamped and fixed rectangular workpiece is turned over, and then the unprocessed surface of the rectangular workpiece can be processed. During this process, the one-way gear 72 is in a non-rotating state, which can ensure that the positions of the reciprocating lead screw 71, the sliding plate 73, the sliding rod 74 and the support plate 75 remain unchanged;

[0050] When machining the clamping surface of the rectangular workpiece, the motor 651 is started. The output end of the motor 651 rotates reversely to drive the rotating shaft 652 to rotate reversely, so that the one-way gear 72 rotates. Then, the reciprocating lead screw 71 is driven to rotate by the rotation of the one-way gear 72, so that the support plate 75 moves up to the highest position. At this time, the air cylinder 52 is started. The output end of the air cylinder 52 contracts to drive the clamping plate 53 to move reversely, releasing the fixed state of the rectangular workpiece. The rectangular workpiece is supported by the support plate 75 that has moved up to the highest position. At the same time, the rotating plate one 2 rotates reversely by the reverse rotation of the rotating shaft 652. Then, the fixed plate 3, the rotating plate two 51, the air cylinder 52, the clamping plate 53, the limit telescopic rod 54, the one-way bevel gear 62, the worm 63 and the worm gear 64 are driven to rotate reversely with the center of the rotating plate one 2 as the center. When the clamping plate 53 rotates to a suitable position, the motor 651 stops. The air cylinder 52 is started. The output end of the air cylinder 52 extends to drive the clamping plate 53 to move, clamping and fixing the rectangular workpiece. At this time, the clamping surface of the rectangular workpiece is the processed surface, and the unprocessed surface can be exposed. Then, the output end of the motor 651 rotates reversely to drive the rotating shaft 652 to rotate reversely, so that the one-way gear 72 rotates, and then the support plate 75 can move down to the lowest position, and then the surface machining treatment can be carried out.

[0051] Embodiment 2

[0053] Different from Embodiment 1, a plurality of universal wheels 9 are arranged between the rotating plate one 2 and the mounting plate 1.
