Description

Technical Field

[0001] This utility model belongs to the field of pneumatic clamping technology, and more specifically, it relates to a flipping mechanism for machining parts with an auxiliary structure. Background Technology

[0002] Some small parts require double-sided processing during manufacturing. In the traying process, flipping fixtures are often used to replace manual flipping, which helps automated production lines improve the efficiency and alignment accuracy of double-sided processing of parts. Existing flipping fixtures for parts processing generally consist of a support base, a flipping cylinder, a clamping cylinder, and grippers.

[0003] Existing application number: CN202121246710.4. This utility model relates to the field of automated manufacturing, and in particular to an automatic part flipping mechanism. The mechanism includes a base, a linear mechanism, a rotating mechanism, and a clamping mechanism. The base is welded from a base plate, a vertical plate, and square tubing. The base is used to mount the linear mechanism; the linear mechanism consists of a servo motor, a motor mount, a base, a guide rail, a ball screw, and a slider. The linear mechanism is mounted on the vertical plate, with its servo motor facing upwards, and drives the rotating mechanism to move vertically in a linear fashion. The rotating mechanism consists of a connecting plate and a rotating cylinder, and is used to drive the clamping mechanism to rotate, thus flipping the part. The connecting plate is mounted on the slider, and the rotating cylinder is mounted above the connecting plate. The clamping mechanism consists of a connecting angle plate, pneumatic grippers, pads, and clamping plates. The clamping mechanism is mounted on the rotating mechanism and rotates with it. The clamping mechanism is used to clamp the workpiece. The purpose of this utility model is to flip parts that need to be flipped during automated machining processes, and it can be applied to the flipping process in automated machining.

[0004] Based on the above, since the small parts to be processed have differences in size and shape, it is often necessary to change the corresponding model of the gripper. Most of the grippers are connected to the clamping cylinder by bolts. Therefore, workers need to use tools to loosen the fixing bolts of the old grippers one by one, remove the old grippers, and then align the bolt holes of the new grippers with the bolt holes of the clamping cylinder. Finally, they need to tighten the bolts one by one. The whole process has many steps and low efficiency, which seriously slows down the changeover rhythm of processing multi-specification parts and makes it difficult to adapt to the production line's need for rapid workpiece switching. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a flipping mechanism for parts processing with an auxiliary structure. This addresses the issue that existing small parts to be processed often require changing the corresponding model of grippers due to differences in size and shape. The grippers are mostly connected to the clamping cylinder by bolts, so workers need to use tools to loosen the fixing bolts of the old grippers one by one, remove the old grippers, align the bolt holes of the new grippers with the bolt holes of the clamping cylinder, and finally tighten the bolts one by one. The whole process involves many steps and low efficiency, which seriously slows down the changeover rhythm of multi-specification parts processing and makes it difficult to adapt to the needs of rapid workpiece switching on the production line.

[0006] The purpose and effect of this utility model's flipping mechanism for parts processing with an auxiliary structure are achieved by the following specific technical means: A flipping mechanism for machining parts with auxiliary structures includes a base plate, a back plate, a flipping cylinder, a clamping cylinder, a gripper, a first adjusting handwheel, a quick-change assembly, and an auxiliary adjusting assembly. The back plate is disposed above the base plate. The flipping cylinder is disposed on the right side of the back plate. The clamping cylinder is rotatably connected to the right side of the flipping cylinder. The gripper is disposed on the right side of the clamping cylinder. The first adjusting handwheel is rotatably connected above the back plate. The quick-change assembly is disposed above the clamping cylinder and the gripper. The auxiliary adjusting assembly is disposed inside the base plate and the back plate.

[0007] Furthermore, the quick-change assembly includes: a first docking box, a sliding plate, and an operating column; the left end of the first docking box is fixedly connected above the clamping cylinder; two sliding plates are provided, and the two sliding plates are slidably connected inside the first docking box respectively; two operating columns are provided, and the two operating columns are fixedly connected to the outside of the two sliding plates respectively.

[0008] Furthermore, the quick-change assembly also includes: docking posts, a reset spring, and a second docking box; two docking posts are provided, and the two docking posts are respectively fixedly connected to the outside of the two sliding plates; the left and right ends of the reset spring are respectively fixedly connected to the inside of the two sliding plates; the second docking box is fixedly connected above the gripper, and the right end of the first docking box is inserted into the inside of the second docking box.

[0009] Furthermore, the auxiliary adjustment component includes: a longitudinal transmission screw and a lifting slider; the longitudinal transmission screw is coaxially fixedly connected below the first adjustment handwheel; the lifting slider is fixedly connected behind the tilting cylinder, the lifting slider is slidably connected inside the back plate, and the lifting slider is threadedly connected to the longitudinal transmission screw.

[0010] Furthermore, the auxiliary adjustment assembly also includes: a second adjustment handwheel, a driving bevel gear, and a driven bevel gear; the second adjustment handwheel is rotatably connected to the upper left end of the base plate; the driving bevel gear is coaxially fixedly connected to the lower part of the second adjustment handwheel; the driven bevel gear is rotatably connected inside the base plate, and the driven bevel gear meshes with the driving bevel gear.

[0011] Furthermore, the auxiliary adjustment component also includes: a transverse transmission screw and a displacement slider; the transverse transmission screw is coaxially fixedly connected to the right end of the driven bevel gear; the displacement slider is fixedly connected to the bottom of the back plate, the displacement slider is slidably connected to the inside of the base plate, and the displacement slider is threadedly connected to the transverse transmission screw.

[0012] Compared with the prior art, the present invention has the following beneficial effects: First, by setting up quick-change components, when replacing the gripper, there is no need to use tools to remove the bolts. The old gripper can be quickly removed by simply moving the operating column inward. After inserting the second docking box into the first docking box, the operating column is released to complete the installation of the new gripper. The whole process is simplified and convenient, which greatly shortens the time spent on gripper replacement and improves the changeover efficiency of processing multi-specification parts.

[0013] Secondly, by setting up auxiliary adjustment components, the flipping cylinder and grippers can be moved up and down and left and right, easily adjusting the distance between the grippers and the operating surface. This solves the problem of insufficient longitudinal space when flipping large workpieces. The entire adjustment process does not require disassembling or modifying the overall structure of the fixture. It can flexibly adjust the gripper position for workpieces of different sizes and specifications, ensuring stable clamping and precise flipping of the workpiece. This further enhances the adaptability of the fixture to the processing of parts in multiple scenarios and ensures the quality of double-sided processing.

[0014] This invention enables tool-free quick replacement of grippers through quick-change components, significantly reducing gripper replacement time and improving the efficiency of processing and changing multiple specifications of parts. The auxiliary adjustment components enable flexible adjustment of the gripper's up-down and left-right positions, solving the problem of insufficient flipping space for large workpieces and adapting to the processing of multiple specifications of workpieces to ensure double-sided processing quality. It provides equipment support for flexible production of double-sided processing of small parts, reducing production debugging time and maintenance costs. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] Example 1: As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a flipping mechanism for machining parts with an auxiliary structure, including a base plate 1, a back plate 2, a flipping cylinder 3, a clamping cylinder 4, a gripper 5, a first adjusting handwheel 7, and a quick-change assembly; the back plate 2 is disposed above the base plate 1; the flipping cylinder 3 is disposed on the right side of the back plate 2; the clamping cylinder 4 is rotatably connected to the right side of the flipping cylinder 3; the gripper 5 is disposed on the right side of the clamping cylinder 4; the first adjusting handwheel 7 is rotatably connected above the back plate 2; and the quick-change assembly is disposed above the clamping cylinder 4 and the gripper 5.

[0024] The quick-change assembly also includes: docking post 602, reset spring 603, and second docking box 501; two docking posts 602 are provided, and the two docking posts 602 are respectively fixedly connected to the outside of the two sliding plates 6; the left and right ends of the reset spring 603 are respectively fixedly connected to the inside of the two sliding plates 6; the second docking box 501 is fixedly connected above the gripper 5, and the right end of the first docking box 401 is inserted into the second docking box 501.

[0025] The specific usage and function of this embodiment are as follows: When using, if it is necessary to change the model of the gripper 5, first disconnect the wiring harness connecting the gripper 5 and the clamping cylinder 4, and then manually move the two operating columns 601 inward at the same time, which will drive the two sliding plates 6 and the two docking columns 602 to move inward. The two docking columns 602 will retract completely into the first docking box 401. Then, move the gripper 5 to the right to remove it. Take out the new gripper 5, and then insert the second docking box 501 into the outside of the first docking box 401. Release the two operating columns 601. Under the rebound action of the return spring 603, the two docking columns 602 will move outward and insert into the second docking box 501, thereby fixing the gripper 5 and the clamping cylinder 4. Then, reconnect the wiring harness connecting the gripper 5 and the clamping cylinder 4.

[0026] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5 As shown, it also includes an auxiliary adjustment component, which is disposed inside the base plate 1 and the back plate 2.

[0027] The auxiliary adjustment components include: a longitudinal transmission screw 701 and a lifting slider 8; the longitudinal transmission screw 701 is coaxially fixedly connected below the first adjustment handwheel 7; the lifting slider 8 is fixedly connected behind the tilting cylinder 3, the lifting slider 8 is slidably connected inside the back plate 2, and the lifting slider 8 is threadedly connected to the longitudinal transmission screw 701.

[0030] The specific usage and function of this embodiment: After the gripper 5 is replaced, if the workpiece to be flipped is large and the longitudinal distance between the gripper 5 and the operating surface is insufficient to support the workpiece flipping, the first adjusting handwheel 7 can be rotated. The longitudinal transmission screw 701 and the lifting slider 8 together form a threaded transmission mechanism to drive the flipping cylinder 3 to move up and down, thereby adjusting the longitudinal distance between the gripper 5 and the operating surface. Alternatively, the second adjusting handwheel 9 can be rotated. The bevel gear transmission mechanism formed by the meshing of the driving bevel gear 901 and the driven bevel gear 10 drives the transverse transmission screw 1001 to rotate.
