Description

Technical Field

[0001] The utility model relates to the field of turning fixtures, in particular to a workpiece turning fixture for a numerically controlled machine tool. Background Art

[0002] When a tee workpiece is processed by a CNC machine tool, a tee flip fixture is required. At present, there are still certain problems when using the tee flip fixture. For example, when the tee is clamped inside the tee flip fixture, the tee can be flipped on the X axis, but cannot be rotated on the Y axis. This results in that when processing the tee, only one branch of the tee can be processed, and the other branches of the tee cannot be processed quickly. When other branches of the tee need to be processed, the staff needs to re-clamp, resulting in a decrease in processing efficiency. At the same time, the traditional tee flip fixture has a fixed arc groove structure on the fixture that clamps the tee pipe, and can only be used for tee clamps of the same size. When it is necessary to process tees of other sizes, it is necessary to replace the fixture clamp head. However, the existing fixture clamp heads are mostly fixed to the mounting seat with bolts, which is relatively troublesome to replace. Utility Model Content

[0003] The utility model aims to provide a workpiece turning fixture for a numerically controlled machine tool, which has the advantages of improving processing efficiency and facilitating replacement.

[0004] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a workpiece flipping fixture for a CNC machine tool, comprising a flipping disk, the front side of the flipping disk is bolted with a frame, the interior of the frame is rotatably connected with a bidirectional threaded rod through a bearing, a connecting seat is symmetrically arranged on the front side of the frame, the two connecting seats on the opposite sides are rotatably connected with a rotating rod through a bearing, one end of the rotating rod passes through the other side of the connecting seat and is fixedly sleeved with a mounting seat, a clamping seat is arranged on the opposite side of the two mounting seats, limit blocks are symmetrically bolted on the clamping seat and the connecting seat, a limit seat is sleeved between the two limit blocks, grooves are symmetrically opened inside the limit seat, a plug is slidably connected inside the groove, and a slot for cooperating with the plug is opened on the opposite side of the two limit blocks.

[0005] The utility model adopts the above technical scheme, by installing a rotating rod on the connecting seat, and the rotating rod is installed on the mounting seat, which cooperates with the clamping seat installed on the mounting seat. When the turning plate is connected to the external rotating equipment, the clamp can be driven to rotate on the X-axis. When it is necessary to process other branches of the tee head, it is only necessary to rotate the rotating rod to drive the clamping seat on the mounting seat to rotate, so as to drive the tee head workpiece to rotate on the Y-axis with the rotating rod as the axis, which is convenient for the staff to quickly switch different tee head branches and improve the processing efficiency. By installing limit blocks on both the mounting seat and the clamping seat, a limit seat is designed between the two limit seats. When the bolt is pulled out from the slot, the limit seat no longer limits the limit block. When the limit seat is removed from the two limit blocks, the mounting seat and the clamping seat can be separated, which is convenient for replacing the clamping seat, so as to achieve the purpose of quickly replacing clamps of different sizes and improve convenience.

[0006] The utility model is further configured as follows: a sliding block is symmetrically bolted on the connecting seat, and a sliding groove used in cooperation with the sliding block is symmetrically opened on the surface of the frame.

[0007] The above technical solution is adopted to slide and limit the connection seat.

[0008] The utility model is further configured as follows: a connection block is symmetrically threadedly connected on the surface of the bidirectional threaded rod, and the connection block is bolted to the connection seat.

[0009] The above technical solution is adopted to facilitate the movement of the connecting seat.

[0010] The utility model is further configured as follows: a limit bolt threadedly connected to the connecting seat is arranged on the front side of the frame, one end of the limit bolt passes through the other side of the connecting seat and is rotatably connected to a clamping block, and a clamping slot used in conjunction with the clamping block is opened on the mounting seat, and the number of the clamping slots is four.

[0011] The above technical solution is adopted to limit the rotation of the mounting seat.

[0012] The utility model is further configured as follows: a sliding rod is symmetrically bolted to the bottom of the clamping block, and the sliding rod is slidably connected to the connecting block.

[0013] The above technical solution is adopted to slide and limit the block.

[0014] The utility model is further configured as follows: a return spring is sleeved on the surface of the plug and located inside the groove, and a support block is fixedly sleeved on the surface of the plug and located inside the groove.

[0015] By adopting the technical solution, the supporting force of the plug is improved.

[0016] The utility model is further configured as follows: a limiting protrusion is bolted on the clamping seat, and a limiting inner groove used in conjunction with the limiting protrusion is provided on the mounting seat.

[0017] The above technical solution is adopted to limit the clamping seat.

[0018] The utility model is further configured as follows: a rotating disk is arranged on the front side of the frame, and the rotating rods are fixedly sleeved with each other.

[0019] The adoption of the technical solution makes it convenient for the rotating rod to rotate.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The utility model has a rotating rod installed on the connecting seat, a mounting seat installed on the rotating rod, and a clamping seat installed on the mounting seat. When the turning plate is connected to an external rotating device, the fixture can be driven to rotate along the X axis. When other branches of the tee head need to be processed, only the rotating rod needs to be rotated to drive the clamping seat on the mounting seat to rotate, so as to drive the tee head workpiece to rotate along the Y axis with the rotating rod as the axis, which is convenient for the staff to quickly switch between different tee head branches and improve the processing efficiency.

[0022] 2. The utility model installs limit blocks on both the mounting seat and the clamping seat, and designs a limit seat between the two limit seats. When the plug is pulled out from the slot, the limit seat no longer limits the limit block. When the limit seat is removed from the two limit blocks, the mounting seat and the clamping seat can be separated, which is convenient for replacing the clamping seat, thereby achieving the purpose of quickly replacing clamps of different sizes and improving convenience.
