Description

Technical Field

[0001] The utility model relates to the technical field of clamping mechanisms, in particular to a multi-station clamping mechanism for a tungsten rod used for thread milling cutter processing. Background Art

[0002] Tungsten alloy rod is made of metal powder at a specific high temperature. Using special high temperature powder metallurgy technology, tungsten rod has special properties, such as low thermal expansion and good thermal conductivity, and has sufficient electrical resistance and high elastic modulus. Therefore, tungsten rod is widely used in various fields, such as some thread milling cutter processing.

[0003] The patent specification with announcement number CN211490527U discloses a clamping tool for tungsten rod milling cutter processing. The clamping tool for tungsten rod milling cutter processing drives a driving tooth pattern block to move through a cylinder, and a small wheel on the driving tooth pattern block cooperates with the small wheel to move. The driving tooth pattern block drives the transmission gear for transmission, and the transmission gear drives the passive tooth pattern block to move. The passive tooth pattern block drives the connecting plate and the first clamping block to move, and cooperates with the second clamping block to clamp or loosen, thereby achieving the purpose of convenient batch clamping and higher processing efficiency.

[0004] However, in the implementation of relevant technologies, it was found that the clamping tooling for tungsten rod milling cutter processing designed above has the following problems: the first clamping block and the second clamping block in the above scheme are of fixed sizes, while the tungsten rod used for thread milling cutter processing has different diameters. Therefore, in the process of clamping the tungsten rod by the first clamping block and the second clamping block, only a relatively fixed tungsten rod diameter can be clamped, which has certain limitations. In view of this, a multi-station clamping mechanism for tungsten rods for thread milling cutter processing is provided to overcome the above defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a multi-station clamping mechanism for a tungsten rod used for thread milling.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a multi-station clamping mechanism for tungsten rods for thread milling cutter processing, including a mounting frame, a driving assembly is installed inside the mounting frame, a first clamping plate is fixedly installed above the driving assembly, a second clamping plate is arranged on one side of the first clamping plate, an adjustment structure is arranged between the first clamping plate and the second clamping plate, the adjustment structure includes a rotating rod, the rotating rod is threadedly installed between the first clamping plate and the second clamping plate, and a third clamping plate is rotatably installed on one side of the rotating rod through a bearing.

[0007] As a further description of the above technical solution: the second clamping plate is fixedly mounted on the mounting frame, and the second clamping plate is fixedly mounted on the mounting frame, so only the first clamping plate needs to be moved.

[0008] As a further description of the above technical solution: the driving component includes a driving motor, the driving motor is fixedly installed on one side of the mounting frame, a screw is fixedly installed on the output end of the driving motor, a bearing seat is threadedly installed on the outer side of the screw, a sliding groove is provided at the connection between the bearing seat and the first clamping plate, and the sliding groove is provided on the bearing seat, and the driving component can adjust the position of the first clamping plate.

[0009] As a further description of the above technical solution: the bearing seat is fixedly mounted on the inner wall of the mounting frame, and the bearing seat is fixedly mounted on the mounting frame, so that when the driving motor rotates or the mounting frame is flipped, the bearing seat will not shake or move.

[0010] As a further description of the above technical solution: a slider is fixedly installed inside the slide groove, the first clamping plate is fixedly installed on the slider, and the slider and the screw are threadedly installed, and the slider can drive the upper first clamping plate to move.

[0011] As a further description of the above technical solution: a slide rail matching the slide groove is provided at the connection between the mounting frame and the slide groove, and the slide rail is provided on the mounting frame. The provision of the slide rail facilitates the movement of the first clamping plate.

[0012] As a further description of the above technical solution: a fixing ring is installed at the connection between the slider and the slide groove, a fixing rod is passed through the middle of the fixing ring, and the fixing rod is fixedly installed inside the bearing seat. The fixing ring and the fixing rod can fix the position of the slider to prevent the slider from escaping from the slide groove when sliding.

[0013] The utility model has the following beneficial effects:

[0014] 1) Rotate the rotating rod of the adjustment structure. Since the connection between the first clamping plate, the second clamping plate and the rotating rod is a fixed thread, when the rotating rod rotates, it will push the third clamping plate at the front end to move. In this way, by adjusting the distance between the third clamping plate and the first clamping plate and the second clamping plate, or directly removing the third clamping plate through the rotating rod, tungsten rods of different diameters can be clamped;

[0015] 2) The driving motor of the driving assembly drives the screw to rotate. Since the slider and the screw are threadedly installed, when the screw rotates, the slider will also rotate and drive the first clamping plate to move, thereby shortening the distance between the first clamping plate and the second clamping plate to clamp the tungsten rod. A fixing rod is provided inside the bearing seat, and a fixing ring is provided outside the fixing rod. The fixing ring is fixedly installed on the slider. Therefore, the fixing rod can fix the position of the fixed block and the slider to prevent the slider from falling when the slider slides. BRIEF DESCRIPTION OF THE DRAWINGS
