DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0017] Please refer to Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of the overall cross-sectional structure of the synchronous clamp provided by the utility model; Figure 2 This is a schematic diagram of the overall right side structure of the synchronous clamp provided by the utility model.

[0018] In the specific implementation process, Figure 1 and Figure 2 As shown, a synchronous clamp includes a clamp body 7, a telescopic mechanism 6, a first moving member 1, a second moving member 2, a synchronous transmission mechanism 3, a first synchronous clamp block 4 and a second synchronous clamp block 5. The first moving member 1, the second moving member 2 and the synchronous transmission mechanism 3 are all arranged in the clamp body 7. The telescopic rod 61 of the telescopic mechanism 6 is fixedly connected to the first moving member 1. The synchronous transmission mechanism 3 is respectively connected to the first moving member 1 and the second moving member 2. The first synchronous clamp block 4 is arranged on the first moving member 1, and the second synchronous clamp block 5 is arranged on the second moving member 2. The first synchronous clamp block 4 and the second synchronous clamp block 5 form a clamp cavity for clamping a special-shaped pipe. Specifically, the clamp body 7 is provided with an installation cavity 73. The first moving member 1, the second moving member 2 and the synchronous transmission mechanism 3 are transmission-connected in the installation cavity 73. When the telescopic mechanism 6 pushes the first moving member 1 to close, the first moving member 1 moves in the opposite direction synchronously with the second moving member 2 based on the synchronous transmission mechanism 3, that is, the first synchronous clamp block 4 and the second synchronous clamp block 5 synchronously clamp the workpiece. The structure is simple and has good practicality.

[0019] It should be noted that the clamp body 7 is provided with a bottom plate 72 for fixing. The synchronous clamp is installed on the workbench based on the bottom plate 72.

[0020] The telescopic mechanism 6 is fixedly connected to the clamp body 7. Specifically, the telescopic mechanism 6 is a cylinder, and the telescopic mechanism 6 and the clamp body 7 can be fixedly connected by connecting members such as bolts. The telescopic mechanism 6 is provided with an active cavity 62 for the first movable member to move, which can reduce the volume of the synchronous clamp.

[0021] A guide plate 9 for guiding is arranged on the clamp body 7. Specifically, the guide plate 9 is arranged on both sides of the first moving member 1 and the second moving member 2, and can guide the two moving members to move.

[0022] The synchronous transmission mechanism 3 is a synchronous gear. Specifically, the first moving member 1 is provided with a first tooth row 11 that meshes with the synchronous gear, and the second moving member 2 is provided with a second tooth row 21 that meshes with the synchronous gear. Based on the meshing relationship between the synchronous gear and the first tooth row 11 and the second tooth row 21, the first moving member 1 and the second moving member 2 achieve synchronous opposite movement, that is, the first clamp and the second clamp close to clamp the workpiece.

[0023] It should be noted that the first movable member 1 is in a "Z" shape and is arranged at the bottom of the installation cavity 73. A clamp pressure block 71 is arranged on the first movable member 1. The first tooth row 11, the second tooth row 21 and the synchronous gear are all on the left side of the clamp pressure block 71. The second movable member 2 is on the left side of the clamp pressure block 71, and the telescopic rod 61 of the telescopic mechanism 6 is connected to the first connecting member on the right side of the first movable member 1.

[0024] The first clamp block is provided with a first clamping groove for clamping, and the second clamp block is provided with a second clamping groove for clamping. The clamping cavity 8 is composed of the first clamping groove and the second clamping groove, and the shapes of the first clamping groove and the second clamping groove are both triangular, that is, the clamping cavity 8 is rhombus-shaped, and can clamp pipes of various shapes. Specifically, the first clamp block and the second clamp block are both provided with a through hole for convenient installation, and correspondingly, the first moving member 1 and the second moving member 2 are provided with a mounting groove, and the bolts are screwed into the mounting groove through the through holes to complete the fixing of the first clamp block and the second clamp block.

[0025] The working principle provided by the utility model is as follows: when a tubular workpiece is placed in the clamping cavity 8, the telescopic mechanism 6 extends the telescopic rod 61, and the telescopic rod 61 pushes the first movable member 1. At this time, the first movable member 1 drives the gear to rotate under the action of the first tooth row 11. At the same time, the gear moves in the second tooth row 21 to drive the second movable member 2 to move, that is, the first clamp block and the second clamp block are in the position of reducing the clamping cavity 8 until the tubular workpiece is clamped, and the workpiece is fixed and then processed. After the processing is completed, the telescopic mechanism 6 retracts the telescopic rod 61, and the first movable member 1 drives the gear to rotate in the opposite direction under the action of the first tooth row 11. At the same time, the gear synchronously drives the second movable member 2, that is, the first clamp block and the second clamp block release the clamping cavity 8 to remove the workpiece.

[0026] The synchronous clamp provided by the utility model places the components in a clamp body 7, has a compact structure design, occupies a small volume, is easy to operate, and the clamping cavity 8 is diamond-shaped and can clamp special-shaped workpieces. It has a simple structure, is easy to install, and has good convenience.
