[0018] The present utility model will be further described below in conjunction with the drawings and embodiments.
[0019] Please refer to Figures 1 to 3 , where Figure 1 is the overall structural schematic diagram of the synchronous fixture provided by the present utility model; Figure 2 is the overall right-view structural schematic diagram of the synchronous fixture provided by the present utility model; Figure 3 is Figure 2 the cross-sectional structural schematic diagram of A-A in
[0020] In the specific implementation process, as Figures 1 to 3As shown in the figure, a synchronous fixture includes a bottom plate 5, a fixture body 1, a driving mechanism 2, a first fixture block 3, a second fixture block 4, a moving push plate 7 and a driven push plate 6. The fixture body 1 is fixedly connected to the bottom plate 5. The driving mechanism 2 is fixed on one side of the fixture body 1. The moving push plate 7 and the driven push plate 6 are respectively slidably connected to both sides of the fixture body 1. The first fixture block 3 is fixedly connected to the driven push plate 6. The second fixture block 4 is fixedly connected to the active push plate. The driving rod of the driving mechanism 2 is fixedly connected to the active push plate. An active rack 12 is arranged below the active push plate. A driven rack 13 is arranged below the driven push plate 6. A gear 14 is arranged on the fixture body 1. The gear 14 meshes with the active rack 14 and the driven rack 13 at the same time. The first fixture block 3 and the second fixture block 4 are symmetrically arranged. The driving mechanism 2 is drivingly connected to the active push plate, and is linked by the active rack 12, the gear 14 and the driven rack 13, so that the driven push plate 6 moves in the opposite direction, that is, the first fixture block 3 and the second fixture block 4 approach each other simultaneously to perform a clamping action. This structure is simple, practical and convenient.
[0021] A cavity 15 for synchronous transmission is arranged in the fixture body 1. The cavity 15 is used to match the movements of the active rack 12, the gear 14 and the driven rack 13. The gear 14 is located at the center of the cavity 15. The active rack 12 meshes with the gear 14 on one side, and the active rack 12 meshes with the gear 14 on the other side. The active rack 12 and the driven rack 13 are respectively located on the left and right sides of the gear 14. The gear 14, the active rack 12 and the driven rack 13 are horizontally installed in the fixture body 1, which can reduce the height of the fixture body 1 and the volume.
[0022] Convex blocks 11 for serving as guide rails are arranged on both sides of the fixture body 1. The moving push plate 7 is provided with a first clamping plate 71 that cooperates with the convex block 11. A second clamping plate 61 is arranged below the driven push plate 6. The first clamping plate 71 and the second clamping plate 61 are L-shaped plates. The moving push plate 7 and the driven push plate 6 are located above the cavity 15. After the active rack 12, the gear 14 and the driven rack 13 are installed on the fixture body 1, the first clamping plate 71 and the second clamping plate 61 can limit the moving push plate 7 and the driven push plate 6 to slide within the fixture body 1. After the moving push plate 7 and the driven push plate 6 are equipped with the first clamping plate 71 and the second clamping plate 61, the shaking of the active rack 12, the gear 14 and the driven rack 13 can be limited, so as to facilitate the smooth movement of the first fixture block 3 and the second fixture block 4, and has good convenience.
[0023] A detachable first clamping block 31 is arranged on the first fixture block 3. A detachable second clamping block 41 is arranged on the second fixture block 4. The first clamping block 31 and the second clamping block 41 have the same structure. There is a V-shaped groove on both the first clamping block 31 and the second clamping block 41 to facilitate clamping.
[0024] The driving mechanism 2 is an oil cylinder, and the oil cylinder controls the telescopic movement of the driving rod to realize the clamping or loosening of the synchronous fixture.
[0025] The working principle provided by the present utility model is as follows: Place the workpiece 8 between the first fixture block 3 and the second fixture block 4. The driving mechanism 2 drives the driving rod to extend and move the pushing plate 7. The driving rack 12 fixedly connected to the pushing plate 7 advances forward. Under the synchronous transmission of the gear 14, the driven gear 14 moves in the opposite direction, that is, the driven pushing plate 6 and the first fixture block 3 move in the opposite direction. The first fixture block 3 and the second fixture block 4 approach each other, indicating that the first clamping block 31 of the first fixture block 3 and the second clamping block 41 of the second fixture block 4 perform a clamping action to clamp the workpiece 8. After clamping, other devices process the workpiece 8. After the processing is completed, the driving mechanism 2 drives the driving rod to retract and move the pushing plate 7. The driving rack 12 fixedly connected to the pushing plate 7 retracts. Similarly, the driven gear 14 moves in the opposite direction, that is, the driven pushing plate 6 and the first fixture block 3 move in the opposite direction. The first fixture block 3 and the second fixture block 4 move away from each other, indicating that the first clamping block 31 of the first fixture block 3 and the second clamping block 41 of the second fixture block 4 perform a loosening action, and the workpiece 8 is taken off, completing a series of clamping and loosening actions.
[0026] The synchronous fixture provided by the present utility model integrates the transmission components in the fixture body 1. The gear 14, the driving rack 12, and the driven rack 13 are horizontally installed in the fixture body 1, which can reduce the height of the fixture body 1, reduce the occupied volume, and has a compact structural design. Driven and controlled by a driving mechanism 2 and cooperating with the V-groove clamping block, it can stably clamp the workpiece 8, has a simple structure and is convenient to install, and has good convenience.
