[0038] like Figure 3 to Figure 4 As shown, the vertical plate 6 is fixedly connected to the top outer wall of the base 1, the motor 4 is fixedly connected to the outer wall of the vertical plate 6, the output shaft of the motor 4 is fixedly connected to the outer wall of the fixed plate 201, and the fixed plate 201 is rotatably connected to the outer wall of the vertical plate 6.

[0041] The above scheme is adopted: four groups of clamping blocks 206 in the clamping mechanism 2 are provided, and four groups of corresponding guide grooves 202 are provided. The four groups of clamping blocks 206 can contact and clamp the four surfaces of the steel billet body 5; the sliding rod 205 can move in the inner wall of the guide groove 202, and the rotating plate 203 is provided with two groups, one group is arranged horizontally, and the other group is arranged vertically, and both can rotate in the inner wall of the fixed plate 201, and each group of rotating plates 203 is provided with two groups of inclined grooves 204. When the rotating plate 203 rotates, the inner wall of the inclined groove 204 will produce pressure on the sliding rod 205 to move it, and under the guiding action of the guide groove 202, it moves to the middle or both sides at the same time; the limit assembly is arranged on the outer wall of the synchronous wheel A207, and the rotatable limit assembly drives the synchronous wheel A207 to rotate, and drives the synchronous wheel B209 and the corresponding rotating plate 203 to rotate synchronously through the transmission effect of the synchronous belt 208.

[0042] like Figure 5 As shown, the limit assembly includes a rotating rod 2001, the inner wall of the rotating rod 2001 is elastically connected to a block 2003 through a connecting spring 2002, the inner wall of the rotating rod 2001 is slidably connected to a ramp block 2004, the outer wall of the ramp block 2003 is fixedly connected to a moving rod 2005, the outer wall of the ramp block 2004 is fixedly connected to a control rod 2006, the outer wall of the fixed plate 201 is fixedly connected to a fixed block 2007, and the outer wall of the fixed block 2007 is provided with a slot 2008.

[0043] The above scheme is adopted: the rotating plate 203 can be driven to rotate and fixed by the limiting assembly, so as to fix the positions of the four groups of clamping blocks 206; two groups of limiting assemblies are provided, which are fixed on the outer walls of the two groups of synchronous wheels A207; the rotating rod 2001 is rotatably connected with the fixed block 2007, and the rotating rod 2001 can be fixed and limited by the clamping block 2003 inside the rotating rod 2001 and the clamping groove 2008 opened on the outer wall of the fixed block 2007; the clamping groove 2008 is opened on the outer wall of the fixed block 2007 in a circular array shape, and multiple groups are provided, so that the rotating plate 203 can be rotated to multiple positions for fixing, so as to adjust the clamping block 206 to different positions to adapt to the steel billet body 5 of different sizes.

[0044] like Figure 5 As shown, the rotating rod 2001 is fixedly connected to the outer wall of the synchronous wheel A207, one end of the connecting spring 2002 is fixedly connected to the outer wall of the block 2003, and the other end of the connecting spring 2002 is fixedly connected to the inner wall of the rotating rod 2001; the block 2003 is slidably connected to the inner wall of the rotating rod 2001, the block 2003 is engaged with the slot 2008, the moving rod 2005 is slidably connected to the outer wall of the inclined block 2004, and the control rod 2006 is slidably connected to the inner wall of the rotating rod 2001.

[0045] The above scheme is adopted: the rotating rod 2001 passes through the outer wall of the fixed plate 201, and the control rod 2006 passes through the outer wall of the rotating rod 2001. When the control rod 2006 is pressed, the inclined surface block 2004 can be driven to move synchronously; under normal conditions, the connecting spring 2002 drives the card block 2003 to remain in a state of popping out and engaging with a group of card slots 2008 due to its own elastic force. At this time, the moving rod 2005 is in contact with the long side inclined surface of the inclined surface block 2004; the moving rod 2005 can only be moved vertically in the inner wall of the rotating rod 2001. When the control rod 2006 is pressed to drive the inclined plane block 2004 to move, the moving rod 2005 will move along the inclined plane of the inclined plane block 2004 and move to the short side of the inclined plane block 2004, thereby driving the card block 2003 to move synchronously into the inner wall of the rotating rod 2001 and disengage from the card slot 2008, so that the limit can be released and the rotating rod 2001 can be rotated; when it is rotated to the appropriate position, the connecting spring 2002 drives the card block 2003 to pop out and engage with the corresponding card slot 2008 to complete the limit.

[0046] like Figure 6 to Figure 7As shown, the inner wall of the protrusion 301 is elastically connected to the trapezoidal block 303 through the telescopic spring 302, the inner wall of the protrusion 301 is slidably connected to the connecting rod 304, the inner wall of the protrusion 301 is slidably connected to the plug block 305, and the outer wall of the rubber block 306 is provided with a slot 307; the buffer block 308 is fixedly connected to the top outer wall of the base 1, one end of the telescopic spring 302 is fixedly connected to the outer wall of the trapezoidal block 303, and the other end of the telescopic spring 302 is fixedly connected to the inner wall of the protrusion 301; the trapezoidal block 303 is slidably connected to the inner wall of the protrusion 301, one end of the connecting rod 304 is fixedly connected to the outer wall of the plug block 305, and the other end of the connecting rod 304 is slidably connected to the outer wall of the trapezoidal block 303, the plug block 305 is engaged with the slot 307, and the rubber block 306 contacts the inner wall of the groove 309.

[0047] The above scheme is adopted: the buffer mechanism 3 is provided with four groups, and a group of protrusions 301 are provided on the outer wall of the fixed plate 201 every ninety degrees. When the motor 4 drives the fixed plate 201 to rotate, the protrusions 301 and the rubber blocks 306 will contact the buffer blocks 308 when rotating ninety degrees or one hundred and eighty degrees, thereby increasing the friction and reducing the vibration when the steel billet body 5 is flipped into place; the outside of the groove 309 is set as an arc surface, and when the rubber block 306 contacts the arc surface of the groove 309, it will produce a certain deformation and thereby increase the friction.

[0048] like Figure 7 As shown, two groups of plug blocks 305 and connecting rods 304 are provided, which are symmetrically distributed on both sides of the trapezoidal block 303. Due to the elastic force of the telescopic spring 302 itself, the trapezoidal block 303 is kept at a certain position in the protrusion 301. At this time, the two groups of connecting rods 304 are in contact with the short side slopes of the trapezoidal block 303, so that the plug block 305 is always engaged with the slot 307 to fix the rubber block 306; the outer wall of the trapezoidal block 303 is provided with a long rod, which passes through the outer wall of the protrusion 301. When the long rod is turned, the trapezoidal block 303 can be driven to move The inclined surface squeezes the two groups of connecting rods 304 to move them horizontally to both sides, which can drive the plug block 305 to move synchronously and disengage from the slot 307, so that the rubber block 306 can be easily and quickly removed for replacement; the rubber block 306 will wear out due to long-term contact and friction with the inner wall of the groove 309. When installing a new rubber block 306, the long rod is also moved to drive the trapezoidal block 303 to move, so that the rubber block 306 can be inserted into the protrusion 301, and the installation is completed by the plug block 305 and the slot 307. The operation is simple.

[0049] The working principle and use process of the present invention:

[0050] According to the size specifications of the steel billet body 5 to be turned over, the clamping mechanism 2 is adjusted. The control rod 2006 can be pressed first to drive the inclined surface block 2004 to move, so that the moving rod 2005 moves along the inclined surface of the inclined surface block 2004, and drives the clamping block 2003 to move toward the inner wall of the rotating rod 2001, and disengages from the clamping groove 2008, thereby releasing the limit on the rotating rod 2001; then the rotating rod 2001 is rotated, and the synchronous wheel A207 rotates and the transmission effect of the synchronous belt 208 drives the synchronous wheel B209 and the rotating plate 203 to rotate. When the rotating plate 203 rotates, the inclined groove 204 generates pressure on the sliding rod 205. Under the guiding effect of the guide groove 202, the clamping block 206 moves to the middle or both sides at the same time until it is adjusted to a suitable position that can contact the surface of the steel billet body 5; the control rod 2006 is released, and the connecting spring 2002 drives the clamping block 2003 to pop out, and engages with the corresponding clamping groove 2008 to fix the position of the clamping block 206.

[0051] Clamping the steel billet: Move the clamping mechanism 2 with the clamping blocks 206 adjusted to the steel billet body 5, so that the four groups of clamping blocks 206 contact the four surfaces of the steel billet body 5 respectively, to complete the clamping and fixing of the steel billet body 5; then start the motor 4, and the output shaft of the motor 4 drives the fixed plate 201 to rotate, thereby driving the clamping mechanism 2 and the clamped steel billet body 5 to rotate, and the control system is used to set the motor 4 to rotate ninety degrees or one hundred and eighty degrees to realize the flipping of the steel billet body 5.

[0052] When the motor 4 drives the fixed plate 201 to rotate close to the target angle, the rubber block 306 on the outer wall of the fixed plate 201 contacts the buffer block 308 on the outer wall of the top end of the base 1. The outer arc surface of the groove 309 of the buffer block 308 causes the rubber block 306 to deform when it contacts it, increasing the friction and resistance of rotation, reducing the inertia of the steel billet body 5 during rotation, causing it to gradually slow down and stop accurately at the target angle, reducing the vibration amplitude.

[0053] After the billet body 5 is turned over, the limit assembly is operated to rotate the rotating rod 2001 in the opposite direction, so that the clamping block 206 releases the billet body 5, and the billet body 5 is placed at a designated position, thus completing a billet turning operation.

[0054] When the rubber block 306 is seriously worn due to long-term friction with the groove 309, the long rod on the outer wall of the trapezoidal block 303 is moved to drive the trapezoidal block 303 to move, and its inclined surface squeezes the connecting rod 304 to make the plug block 305 disengage from the slot 307. The old rubber block 306 is removed and a new rubber block 306 can be installed. After replacing the new rubber block 306, the long rod is moved again, and the rubber block 306 is inserted into the protrusion 301, and the installation is completed by the plug block 305 and the slot 307 being engaged.
