Technical Field
[0001] This utility model belongs to the field of workpiece processing, specifically, it relates to a machine tool auxiliary tensioning device. Background Technology
[0002] Machine tool auxiliary tensioning equipment is mainly used to fix workpieces or cutting tools during machine tool processing to ensure their stability and accuracy.
[0003] Commonly used tensioning equipment tightens and fixes workpieces by clamping them with pressure on both sides. This means that after each workpiece is tightened and processed by the robotic arm, it needs to be released, during which the machine stops working, resulting in slowed processing efficiency. Therefore, there is an urgent need for an auxiliary tensioning device that does not affect the processing efficiency of machine tools.
[0004] In view of this, this utility model is proposed. Utility Model Content
[0005] To solve the technical problems existing in the above-mentioned tensioning equipment, the basic concept of the technical solution adopted by this utility model is as follows:
[0006] A machine tool auxiliary tensioning device, comprising:

Each guide rod is parallel and flush with the inclined surface of the pressure block. Limiting blocks are fixedly connected to the inclined surface of each guide rod. Limiting blocks are rectangular blocks.
[0008] Push blocks are symmetrically arranged on both sides of the pressure block. The push blocks are rods with a right-angled triangular cross-section. The inclined surface of the push block can be parallel to the inclined surface of the pressure block. Guide rails are symmetrically fixed to the inclined surface of the push blocks. The guide rails are rods with an inverted L-shaped cross-section. Each guide rail can slide along the corresponding guide rail notch. A limiting groove is opened at the opening of the guide rail.

The rotating plate is fixedly connected to the bottom of the flip plate and is also rotatably connected to the wall of the mounting frame. The servo motor is fixedly connected to the side wall of the mounting frame. The bottom of the rotating plate mirrors the structure of the top.
[0010] In a preferred embodiment of this utility model, the flap is a rectangular plate, and a threaded groove adapted to the size of the screw is opened through the center of the top of the flap. The screw can pass through the center of all flaps and the threaded groove at the same time and be threadedly connected.
[0011] In a preferred embodiment of this utility model, the clamping block is a rectangular rod, which is symmetrically fixedly connected to both sides of the flip plate.

The same limiting plate is also mirrored on the wall surface of the flip plate below, and the same retaining groove is also opened on the wall surface of the pressure block below.
[0013] In a preferred embodiment of this utility model, the limiting plate is a rectangular plate, and the symmetrical limiting plates are located on both sides of the central screw groove of the flip plate. Each set of symmetrical limiting plates can pass through the symmetrical retaining groove of the corresponding pressing block wall.
[0014] In a preferred embodiment of the present invention, the side wall plane of the push block is symmetrically fixedly connected with movable rods, the movable rods being rectangular strips, and each clamping block is symmetrically fixedly connected with a clamping rod on the side wall plane facing the push block plane.
[0015] In a preferred embodiment of this utility model, the fixing rod is also in the form of a rectangular strip, and the upper and lower symmetrical fixing rods of each group are flush with the corresponding movable rods of each group.
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] 1. By setting up a conversion structure, the position of the workpiece can be changed by rotating the positions of the upper and lower symmetrical flip plates.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a machine tool auxiliary tensioning device includes: a pressure block 20, which is in the shape of an inverted isosceles trapezoid; guide rods 21 are symmetrically fixedly connected to the front and rear walls of the pressure block 20; the guide rods 21 are rectangular rods; each guide rod 21 is parallel and flush with the inclined surface of the pressure block 20; and a limiting block 22 is fixedly connected to the inclined surface of each guide rod 21; the limiting block 22 is rectangular.
[0029] Push blocks 23 are symmetrically arranged on both sides of pressure block 20. Push blocks 23 are rods with a right-angled triangular cross-section. The inclined surface of push blocks 23 can be parallel to the inclined surface of pressure block 20. Guide rails 24 are symmetrically fixedly connected to the inclined surface of push blocks 23. Guide rails 24 are rods with an inverted L-shaped cross-section. Each guide rod 21 can slide along the notch of the corresponding guide rail 24. A limiting groove 25 is opened at the opening of the guide rail 24. The limiting groove 25 can be adapted to the sliding of the corresponding limiting block 22. This is existing technology, so it will not be described in detail here.
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the conversion structure is set on the wall of the pressure block 20 for changing the position of the workpiece. The conversion structure includes: a flip plate 30, a screw 32, a threaded groove 33, a clamping block 35, a rotating plate 36, a fixed frame 37, and a servo motor 38. The flip plate 30 is set below the pressure block 20. The screw 32 is threaded to the wall of the flip plate 30. The threaded groove 33 is opened through the top center of the pressure block 20. The clamping block 35 is symmetrically fixed to the top of the flip plate 30. The rotating plate 36 is fixedly connected to the bottom of the flip plate 30. The rotating plate 36 is also rotatably connected to the wall of the fixed frame 37. The servo motor 38 is fixedly connected to the side wall of the fixed frame 37. The bottom of the rotating plate 36 is mirrored with the same structure as the top.
[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the flap 30 is a rectangular plate, and a threaded groove adapted to the size of the screw 32 is opened through the center of the top of the flap 30. The screw 32 can pass through the center of all flaps 30 and the threaded groove 33 and be threaded together simultaneously. The clamping block 35 is a rectangular rod, and the clamping block 35 is symmetrically fixedly connected to both sides of the flap 30. The rotating plate 36 is a rectangular plate, and the rotating plate 36 is symmetrically arranged on both sides of the flap 30. The frame 37 is a U-shaped frame, and the symmetrical rotating plates 36 can be rotated and connected within the cavity of the frame 37. The servo motor 38 can... The drive plate 36 rotates, and the conversion structure also includes a limiting plate 31 and a retaining groove 34. The limiting plate 31 is symmetrically fixedly connected to the top of the flip plate 30, and the retaining groove 34 is symmetrically opened through the top of the pressure block 20. The wall surface of the flip plate 30 below is also mirrored with the same limiting plate 31, and the wall surface of the pressure block 20 below is also opened with the same retaining groove 34. The limiting plate 31 is a rectangular plate, and the symmetrical limiting plates 31 are located on both sides of the central screw groove of the flip plate 30. Each set of symmetrical limiting plates 31 can pass through the symmetrical retaining groove 34 on the wall surface of the corresponding pressure block 20.
[0032] In practical use, first place the workpiece to be clamped between the upper push block 23 and the fixed clamping block 35. Then, turn the screw 32 downwards. As the screw 32 rotates, the upper pressure block 20 moves downwards simultaneously through the threads on its wall. The retaining groove 34 on the wall of the pressure block 20 moves downwards along the limiting plate 31. As the pressure block 20 moves, the symmetrical push blocks 23 on both sides move smoothly to the sides due to the downward pressure. When the push blocks 23 move, the guide rail 24 moves relative to the guide rod 21. As the push blocks 23 move toward the fixed clamping block 35, the workpiece is clamped and tightened. At this time, the workpiece can be processed. The push block 23 and the fixed clamping block 35 on the other side can also be used to place the workpiece to be processed. After the workpiece above is processed... Start the servo motor 38, which drives the rotating plate 36 to rotate 180 degrees. As the rotating plate 36 rotates, the upper and lower structures of the rotating plate 36 will be swapped. The finished workpiece will be located directly below. Then, the next workpiece to be processed is placed between the two push blocks 23 and the clamping block 35 above. Then, the screw 32 is turned downwards. At this time, the pressure block 20 located above will move downwards due to the rotation of the screw 32, and in the same process, it will drive the push blocks 23 on both sides to move towards the clamping block 35, thereby clamping and fixing the workpiece above. During this process, the pressure block 20 located below will move downwards at the same time. As the pressure block 20 moves downwards, the push blocks 23 on both sides will move closer to each other, thereby releasing the workpiece below.
[0033] In summary, by setting up a conversion structure, the position of the workpiece can be changed by rotating the positions of the upper and lower symmetrical flip plates 30. Furthermore, when fixing the unprocessed workpiece, the processed workpiece can be released synchronously. Therefore, this solution will not reduce processing efficiency due to changing the workpiece for processing.
[0034] like Figure 4 and Figure 5 As shown, the side wall plane of the push block 23 is symmetrically fixed with movable rods 40, which are rectangular strips. Each clamping block 35 is symmetrically fixed with fixed rods 41 on the side wall facing the plane of the push block 23. The fixed rods 41 are also rectangular strips. Each set of symmetrical fixed rods 41 is flush with the corresponding movable rods 40.
[0035] In practical use, when the push block 23 moves, it will drive the symmetrical movable rod 40 on its wall to move synchronously toward the corresponding fixed rod 41, and can also clamp the workpiece when it is placed horizontally between the fixed rod 41 and the movable rod 40.
[0036] In summary, by setting up the movable rod 40 and the fixed rod 41, the solution can clamp and hold both vertically placed and horizontally placed workpieces through symmetrical arrangement, thereby effectively improving the applicability of the solution.
[0037] Working principle: First, place the workpiece to be clamped between the upper push block 23 and the fixed clamping block 35. Then, turn the screw 32 downwards. As the screw 32 rotates, it drives the upper pressure block 20 to move downwards simultaneously through the threads on its wall. The retaining groove 34 on the wall of the pressure block 20 can move downwards along the limiting plate 31. As the pressure block 20 moves, the downward pressure causes the symmetrical push blocks 23 on both sides to move smoothly to both sides. When the push blocks 23 move, the guide rail 24 moves relative to the guide rod 21. As the push blocks 23 move toward the fixed clamping block 35, the workpiece is clamped and tightened. At this time, the workpiece can be processed. The push block 23 and the fixed clamping block 35 on the other side can also place the workpiece to be processed at the same time. After the workpiece above is processed, start the servo motor 38. 38 can drive the rotating plate 36 to rotate 180 degrees. As the rotating plate 36 rotates, the upper and lower structures of the rotating plate 36 will be swapped. The finished workpiece will be located directly below. Then, the next workpiece to be processed will be placed between the two push blocks 23 and the clamping block 35 above. Then, the screw 32 will be turned downwards. At this time, the pressure block 20 located above will move downwards due to the rotation of the screw 32, and in the same process, it will drive the push blocks 23 on both sides to move towards the clamping block 35, thereby clamping and fixing the workpiece above. During this process, the pressure block 20 located below will move downwards at the same time. As the pressure block 20 moves downwards, the push blocks 23 on both sides will move closer to each other, thereby releasing the workpiece below. After the workpiece above is processed, the same process is repeated.
