[0004] In daily life, it is found that during the process of electrospark machining of workpieces, the workpiece needs to be relatively fixed with the clamping tool on the workbench surface before the machining operation is performed. In this process, due to the poor clamping effect of the usual clamping tools, the clamped workpiece is prone to loose deviation, resulting in unqualified workpiece machining. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that during the electrospark machining of a workpiece, the workpiece needs to be relatively fixed with a clamping tool on the surface of a workbench before the machining operation is performed. During this process, due to the poor clamping effect of the conventional clamping tool, the clamped workpiece is prone to loosening and shifting, resulting in unqualified machining of the workpiece.

[0006] In order to solve the above technical problems, the utility model provides a precision CNC electric spark forming machine tool, including: a machine base and an auxiliary device, the upper surface of the machine base is fixedly connected to a support frame, the lower surface of the support frame is installed with a forming frame, the upper surface of the machine base is installed with a bearing plate with the aid of the auxiliary device, the surface of the bearing plate is provided with an adjusting device, the adjusting device includes four fixed plates, the bottom surfaces of the four fixed plates are fixedly connected to the surface of the bearing plate, the surfaces of the fixed plates are slidably connected to a moving frame, the cross-section of the moving frame is arc-shaped, the upper end surfaces of the four moving frames are fixedly connected to a connecting plate, the arc surfaces of the four connecting plates are threadedly connected with the same fixing ring, and the cross-sectional size of the fixing ring is adapted to the cross-sectional size of the four connecting plates combined.

[0007] The effect achieved by the above-mentioned components is: in the process of electrospark machining of the workpiece, it will be necessary to relatively fix the workpiece to be machined and the clamping tool on the surface of the workbench before performing the machining operation. In this process, due to the poor clamping effect of the usual clamping tools, the clamped workpiece is prone to loose deviation, resulting in unqualified workpiece machining. First, through the support frame on the machine base, the forming frame installed on the lower surface of the support frame is close to the position of the carrier plate. At this time, the moving frame that slides relatively between the surface of the carrier plate and the fixed plate is pulled to place the workpiece in the middle position of the moving frame, and the four moving frames are close to each other to form a complete circle. At this time, the moving frame can be used to squeeze the entire workpiece, and then the fixed ring is used to thread and connect with the connecting plate at the upper end of the moving frame. At this time, the position of the entire moving frame cannot be moved, and at the same time, the position of the workpiece is also firmly fixed, so that the machining components in the forming frame can be used effectively and conveniently for machining.

[0008] Preferably, the inner wall surface of the connecting plate is fixedly connected with a compression pad, and the surface of the compression pad is provided with a plurality of anti-slip grooves.

[0009] The effect achieved by the above components is that in the process of squeezing the moving frame and the workpiece, the squeezing pad fixed on the surface of the moving frame can facilitate and increase the friction, thereby facilitating better processing operations on the workpiece.

[0010] Preferably, a screw rod is threadedly penetrated through one side surface of the movable frame, and the bottom end of the screw rod abuts against the surface of the fixed plate.

[0011] The effect achieved by the above components is that when the position of the moving frame is moved and adjusted, the screw rod on the surface of the moving frame is rotated to temporarily limit and fix the position of the moving frame.

[0012] Preferably, a rotating ring is rotatably connected to the surface of the fixing ring, a fixing belt is fixedly connected to one side of the rotating ring, and one end of the fixing belt away from the rotating ring is fixedly connected to the side wall of the supporting plate.

[0013] The effect achieved by the above components is that when the position of the fixing ring is auxiliary limited, auxiliary fixation can be performed through the rotating ring rotating on the surface of the fixing ring and the fixing belt.

[0014] Preferably, the auxiliary device includes a mounting frame, the bottom end of the mounting frame is fixedly connected to the upper surface of the machine base, a servo motor is fixedly connected to one side of the mounting frame, the output end of the servo motor is fixedly connected to a driving rod, both ends of the driving rod are rotatably connected to the bottom surface of the inner wall of the mounting frame, a connecting block is fixedly connected to the bottom surface of the supporting plate, the inner wall of the connecting block is threadedly connected to the arc surface of the driving rod, a sliding block is fixedly connected to one end of the bottom surface of the supporting plate away from the connecting block, the inner wall of the sliding block slides through a limiting rod, and both ends of the limiting rod are fixedly connected to the inner wall of the mounting frame.

At this time, the driving rod will drive the connecting block at the bottom end of the carrier plate to move its position, so that the carrier plate can slide along the limit rod through the sliding block on one side of the bottom surface, so that the entire carrier plate can easily correspond to the bottom surface of the forming frame.

[0016] Preferably, a protective sleeve is fixedly connected to the inner wall of the sliding block, and the inner wall of the protective sleeve is slidably connected to the surface of the limiting rod.

[0017] The effect achieved by the above components is that when the carrying plate slides through the sliding block and the limiting rod at the bottom, the protective sleeve fixed on the inner wall of the sliding block can effectively protect the sliding block and the limiting rod from sliding, thereby avoiding wear of the inner wall of the sliding block.

[0018] Preferably, both sides of the bottom surface of the carrying plate are rotatably connected with pulleys, and the arc surfaces of the pulleys are slidably connected to both sides of the inner wall of the installation frame.

[0019] The effect achieved by the above components is that in the process of moving and adjusting the position of the carrying plate, the rotating pulleys on both sides of the carrying plate can reduce friction, thereby facilitating better sliding of the position of the carrying plate.

[0020] Compared with the related art, the precision CNC EDM machine tool provided by the utility model has the following beneficial effects:

[0021] The utility model provides a precision CNC electric spark forming machine tool. In the process of electric spark processing of a workpiece, it will be necessary to relatively fix the processed workpiece and the clamping tool on the surface of the worktable before processing. In this process, due to the poor clamping effect of the usual clamping tool, the clamped workpiece is prone to loose deviation, thereby causing unqualified processing of the workpiece. First, through the support frame on the machine base, the forming frame installed on the lower surface of the support frame is close to the position of the bearing plate. At this time, the moving frame on the surface of the bearing plate and the fixed plate are pulled to slide relatively, and the processed workpiece is placed in the middle position of the moving frame, so that four moving frames are close to each other to form a complete circle. At this time, the moving frame can be used to squeeze the entire processed workpiece, and then the fixing ring is used to perform threaded rotation docking with the connecting plate at the upper end of the moving frame. At this time, the position of the entire moving frame cannot be moved, and the position of the processed workpiece is also fixed firmly. The processing components in the forming frame are effectively and conveniently used for processing. By operating the adjusting device, the fixed limit of the processed workpiece on the surface of the bearing plate is achieved, and the position of the processed workpiece is prevented from being offset, thereby causing unqualified processing size.

[0022] During the processing of the workpiece on the surface of the carrier plate, in order to facilitate the adjustment of the position of the carrier plate so that the workpiece can be effectively aligned with the bottom end of the forming frame, the servo motor on one side of the mounting frame is started through the mounting frame fixed on the upper surface of the machine base, and the servo motor drives the driving rod to rotate. At this time, the driving rod will drive the connecting block at the bottom end of the carrier plate to move its position, so that the carrier plate can slide along the limit rod through the sliding block on one side of the bottom surface, so that the entire carrier plate can be easily aligned with the bottom surface of the forming frame. By operating the auxiliary device, the driving rod is rotated, so that the driving rod drives the carrier plate to adjust and limit its position, which is convenient for better regulation of the workpiece.

[0034] The working principle of a precision CNC EDM forming machine tool provided by the utility model is as follows: in the process of EDM processing of a workpiece, it is necessary to relatively fix the workpiece to be processed and the clamping tool on the surface of the workbench before the processing operation is performed.
