Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a slow wire cutting rapid positioning tooling. Background Art

[0002] Slow wire cutting, also known as low-speed wire cutting, is a numerical control machine tool that uses a continuously moving thin metal wire (called the electrode wire, generally copper wire) as the electrode to perform pulsed spark discharge on the workpiece, generating a temperature above 6000 degrees Celsius to erode the metal and cut the workpiece.

[0003] The processing principle of slow wire cutting is the phenomenon of continuous discharge to remove metal in the slit gap between the online electrode and the workpiece. In the prior art, after clamping the workpiece, it is necessary for the staff to manually calibrate and position the workpiece. And since the calibration and positioning are carried out on the processing table, a large part of the processing time is occupied by the calibration and positioning, resulting in a relatively long overall clamping process time and being not conducive to improving production efficiency. In view of this, we propose a slow wire cutting rapid positioning tooling. Summary of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a slow wire cutting rapid positioning tooling, which can solve the problem that after clamping the workpiece, it is necessary for the staff to manually calibrate and position the workpiece, and since the calibration and positioning are carried out on the processing table, a large part of the processing time is occupied by the calibration and positioning, resulting in a relatively long overall clamping process time.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A slow wire cutting rapid positioning tooling includes a bottom plate. Two limiting grooves are opened on the upper surface of the bottom plate, and a driving groove is opened on the upper surface of the bottom plate. A threaded rod is rotatably connected to the inner wall of the driving groove. The right end of the threaded rod rotatably penetrates into the interior of a driving box. The right side surface of the bottom plate is fixedly connected with the driving box. The upper surface of the bottom plate is fixedly connected with two clamping bottom plates. Two sliding blocks are fixedly connected to the lower surface of the clamping bottom plates. The two sliding blocks are respectively slidably connected to the two limiting grooves. Two driving blocks are respectively fixedly connected to the lower surfaces of the two clamping bottom plates. The two driving blocks are both slidably connected to the interior of the driving groove. The two driving blocks are both threadedly sleeved on the outer surface of the threaded rod. A motor is arranged inside the driving box, and the output end of the motor is fixedly connected with the threaded rod. A workpiece is arranged on the clamping bottom plate, and a clamping assembly is arranged on the clamping bottom plate.

[0006] Preferably, the clamping assembly includes two sliding bottom plates. The two sliding bottom plates are both slidably connected to the upper surface of the clamping bottom plate. Two second sliding grooves are opened on the upper surface of the clamping bottom plate. A movement cavity is opened inside the clamping bottom plate. The movement cavity is communicated with the interiors of the two second sliding grooves.

[0007] Preferably, a second sliding block is fixedly connected to the lower surface of the sliding bottom plate. The second sliding block extends into the interior of the second sliding groove and is slidably connected to the second sliding groove. The front and rear inner walls of the movement cavity are respectively rotatably connected to second threaded rods.

[0008] Preferably, first bevel gears are respectively fixedly connected to the adjacent ends of the two second threaded rods. A second motor is fixedly connected to the right side surface of the clamping bottom plate. The output end of the second motor is fixedly connected to a rotating rod.

[0009] Preferably, the left end of the rotating rod rotatably penetrates into the interior of the movement cavity, and a second bevel gear is fixedly connected to the left end of the rotating rod.

[0010] Preferably, both of the first bevel gears are meshed with the second bevel gear, and the two second sliding blocks are respectively threadedly sleeved on the outer surfaces of the two second threaded rods.

[0011] Preferably, a clamping block is slidably connected to the upper surface of the sliding bottom plate. A through groove extending out of its lower surface is formed in the upper surface of the clamping block.

[0012] Preferably, a bolt is threadedly sleeved in the interior of the sliding bottom plate. The upper end of the bolt extends out of the through groove movably. The side surface of the clamping block close to the workpiece is arc-shaped.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] (1). When processing a workpiece with this wire cut rapid positioning tooling, the workpiece is placed on the clamping bottom plate, and then it is clamped and calibrated by the clamping assembly. Then, the motor is used to drive the threaded rod to rotate synchronously. Since the movement trajectories of the two driving blocks are restricted by the driving grooves, when the threaded rod rotates, the two driving blocks will be driven to move horizontally synchronously. When the two driving blocks move, they drive the two clamping bottom plates to move synchronously. At the same time, when the clamping bottom plate moves, the movement trajectory is restricted by means of the two sliding blocks and in cooperation with the limiting grooves. When one of the clamping bottom plates moves to the processing position, processing starts. At the same time, the workpiece is placed on the restricted clamping bottom plate, and the positioning and calibration are completed again by means of the clamping assembly. When the workpiece is processed, the motor is used to move the positioned and calibrated workpiece to the processing position. Through the above structure, it can be made that when this positioning tooling processes with one clamping bottom plate, another part can be placed on the clamping bottom plate to complete the off-machine calibration, and the part can be replaced more quickly after processing without re-calibration, solving the problem that repeated calibration will affect the efficiency.

[0015] (2) After the workpiece is placed, the second motor synchronously drives the rotating rod to rotate. After the rotating rod rotates, it synchronously drives the second bevel gear to rotate. After the second bevel gear rotates, it synchronously drives the two first bevel gears to rotate. The two first bevel gears respectively drive the two second threaded rods to rotate. After the two second threaded rods rotate, they synchronously drive the two second sliding blocks to move. Then, the two second sliding blocks are used to drive the two sliding bottom plates to move in opposite directions. With the two sliding bottom plates, the two clamping blocks are driven to complete clamping. At the same time, the position of the clamping blocks can be finely adjusted by bolts or the clamping blocks can be directly replaced. Through the above structure, clamping can be quickly completed after the workpiece is finished to facilitate subsequent positioning and calibration. At the same time, when processing different workpieces, the clamping blocks can be quickly replaced by bolts. Brief Description of the Drawings

[0025] Working principle: When machining the workpiece 10, the workpiece 10 is placed on the clamping bottom plate 6, and then it is clamped and calibrated by the clamping assembly. Subsequently, the motor 9 synchronously drives the threaded rod 4 to rotate. Since the movement trajectories of the two driving blocks 8 are restricted by the driving grooves 3, when the threaded rod 4 rotates, it will synchronously drive the two driving blocks 8 to move horizontally.
