[0002] The worktable of a machining center is usually equipped with an automatic clamp to meet the needs of rapid clamping of workpieces, making it convenient to build an automated loading and unloading system together with a robot, thereby improving production efficiency and reducing workers' labor intensity. Currently, for machining centers equipped with a fourth-axis rotary table and an A (B) / C cradle turntable, the power medium required for its supporting automatic clamp must reach the rotary worktable surface through a continuous rotary axis. This requires special design or modification of the existing rotary table to meet the above requirements and ensure the safety and reliability of the power transmission device.

[0003] The current fixture power transmission device still has the following shortcomings:

[0004] At present, specially designed rotary worktables are non-standard customizations, and their costs are relatively high. In addition, non-standard customized rotary worktables also have complex structures and stability issues that need to be tested. Moreover, the current worktables cannot guarantee high precision when clamping and limiting the workpiece, which will have a certain impact on the processing quality and has certain limitations. Utility Model Content

[0005] In order to solve the above technical problems, the present invention provides an automatic clamp power transmission device for a machining center to solve the problem raised in the above background technology that the current workbench cannot guarantee high accuracy when clamping and limiting the workpiece, which will have a certain impact on the processing quality and has certain limitations.

[0006] The purpose and effect of the automatic clamping power transmission device for machining centers of this utility model are achieved by the following specific technical means:

[0007] The power transmission device of the automatic clamp of the machining center includes: a workbench; the workbench adopts an internal hollow cylindrical structure; a cylindrical power transmission sleeve is rotatably provided on the inner side of the workbench, and the flange end face of the power transmission sleeve is provided with four power output interfaces, and the front end of the power transmission sleeve has four power input interfaces radially distributed; the front end of the power transmission sleeve is rotatably connected with a rotary distributor; the rotary distributor consists of a rotating inner ring and a fixed outer ring, and the rotating inner ring of the rotary distributor is sleeved on the outside of the power transmission sleeve; four joints are provided on the outside of the fixed outer ring of the rotary distributor in a ring array.

[0008] Furthermore, an adapter is fixedly installed on the rear side of the workbench by bolts, and a guide and centering method is used between the adapter and the workbench; an automated base is fixedly connected to the rear side of the adapter; a clamp is fixedly connected to the rear side of the automated base, and the clamp and the automated base are connected by hydraulic power transmission; a workpiece is provided on the rear side of the clamp, and the workpiece and the clamp can be pre-installed in advance; an auxiliary bracket is fixedly provided on the front side of the workbench.

[0009] Furthermore, a fixing ring with an annular structure is fixedly provided on the outside of the joint, and a circular groove structure is opened on one side of the fixing ring. Four groups of through-type rectangular sliding groove structures are opened on the outside of the fixing ring in an annular array.

[0010] Furthermore, a limiting ring with a circular structure is rotatably arranged in the circular groove of the fixing ring, and a threaded groove structure is provided on one side of the limiting ring; a connecting block with a rectangular block structure is slidably arranged in the rectangular sliding groove outside the fixing ring, and a threaded groove structure is provided on one side of the connecting block to engage with the limiting ring; a splint with an arc-shaped plate structure is fixedly provided on the inner section of the connecting block; an end cover is fixedly connected to the front end of the rotary distributor by bolts, and the end cover is fixedly connected to the auxiliary bracket.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this application, the automated base can be connected to the workbench through the provided adapter, and the medium power (such as oil circuit, gas circuit, etc.) can be transferred to the automated base to ensure the reliability and sealing of the power during the transmission process, and no leakage will occur. In addition, the workbench, the adapter and the automated base all use guided positioning, which makes installation and positioning convenient and highly accurate.

[0013] The gripper and workpiece are pre-assembled and fixed in place. During loading, air is blown through to clean the gripper before the workpiece is placed. The gripper is then tightened by hydraulic oil supply. After it is in place, an air inspection is performed to confirm stability before processing begins. After processing is complete, the pressure is released to remove the workpiece, and the automated base is cleaned with air again. The entire loading and unloading process is scientific and orderly, with each link working closely together, effectively improving processing efficiency. During the loading and unloading process, air is blown through the connection between the automated base and the gripper to ensure that the interface is free of chips and dust, avoiding any impact on the connection and positioning accuracy. This helps ensure subsequent processing quality and improves equipment reliability.

[0014] The outside of the joint is equipped with a retaining ring, a limiting ring, a connecting block, and a clamping plate. Rotating the limiting ring causes the connecting block to slide, allowing the clamping plate to securely clamp the pipe to the outside of the joint. This maintains the stability of the pipe-to-joint connection, helps ensure normal operation of the equipment, and improves its overall reliability. Furthermore, the end cap at the front of the rotary distributor is fixedly connected to an auxiliary bracket, further enhancing the stability of the equipment structure.

[0025] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples.

[0026] Example 1: As shown in the attached Figure 1 To the attached Figure 9 As shown:

[0027] The utility model provides a power transmission device for an automatic clamp of a machining center, comprising: a workbench 1; the workbench 1 adopts a cylindrical structure with a hollow interior; a power transmission sleeve 105 with a cylindrical structure is rotatably provided on the inner side of the workbench 1, and the flange end face of the power transmission sleeve 105 is provided with four power output interfaces, and four power input interfaces are radially distributed at the front end of the power transmission sleeve 105; a rotary distributor 2 is rotatably provided at the front end of the power transmission sleeve 105; the rotary distributor 2 is composed of a rotating inner ring and a fixed outer ring, and the rotating inner ring of the rotary distributor 2 is sleeved on the outer side of the power transmission sleeve 105; four joints 201 are provided in a ring array on the outer side of the fixed outer ring of the rotary distributor 2.

[0028] Among them, the back side of the workbench 1 is fixedly installed with an adapter adapter 101 by bolts, and the adapter adapter 101 and the workbench 1 are guided and centered; the back side of the adapter adapter 101 is fixedly connected with an automated base 102; the back side of the automated base 102 is fixedly connected with a clamper 103, and the clamper 103 and the automated base 102 are connected by hydraulic power transmission; the back side of the clamper 103 is provided with a workpiece 104, and the workpiece 104 and the clamper 103 can be pre-installed in advance; the front side of the workbench 1 is fixedly provided with an auxiliary bracket 106.

[0029] The specific usage and function of this embodiment are as follows:

[0030] The clamp 103 and the workpiece 104 are pre-assembled and fixed in advance. When processing and loading, air is first introduced through the air inlet pipe, and the connection between the automation base 102 and the clamp 103 is blown clean to ensure that there is no chips and dust at the interface to avoid affecting the connection and positioning accuracy of the clamp 103 and the automation base 102, which is conducive to ensuring the subsequent processing quality. Then, the clamp 103 and the workpiece 104 are placed on the automation base 102 by the manipulator, and then oil is introduced through the hydraulic oil inlet pipe. The hydraulic oil passes through the joint 201, the rotary distributor 2, the power transmission sleeve 105 and the transfer adapter 101 in sequence, and finally reaches the automation base 102. At the base 102, the automated base 102 tightens the clamp 103 through oil pressure, and after it is in place, air is taken in through another set of air pipes for air inspection to confirm the stability of the connection between the clamp 103 and the workpiece 104. After the confirmation is completed, the workpiece 104 can be processed according to the established procedure. After the processing is completed, the oil pressure is relieved at the automated base 102, and the limiting effect on the clamp 103 is lost. The clamp 103 and the workpiece 104 can be taken out by the robot arm, and then the automated base 102 is blown clean again through the air intake pipe to ensure that the automated base 102 remains clean, completing the entire loading and unloading process.
