[0002] Before the alloy bars are processed by machine tools, in order to prevent the alloy bars from moving during the processing and affecting the processing accuracy, the alloy bars need to be clamped and positioned before subsequent processing.

[0003] The Chinese patent with publication number CN218225661U discloses a positioning fixture for processing special alloy bars, which relates to the technical field of clamping devices. The positioning fixture for processing special alloy bars includes a first fixed seat, and a bar matching installation assembly is welded above the first fixed seat; the bar matching installation assembly is fixedly connected to the bar clamping assembly through a crossbeam. Although the above patent can clamp and position the alloy bars, during the clamping and positioning process, one end of the alloy bar is first in a fixed disk, and then the alloy bar is in a suspended state and is clamped and fixed by the clamping disk.

There are four connecting springs 107 evenly spaced between the right side surface of the movable plate 106 and the right side surface of the movable seat 3. The middle of the bottom of the movable seat 3 The embedded sliding connection is provided with a slide bar 104, the upper part of which contacts the inclined surface of the movable plate 106. When the slide bar 104 moves upward, the slide bar 104 can drive the movable plate 106 to move to the left. A trigger plate 105 is fixedly connected to the inner side of the machine tool 1. The trigger plate 105 corresponds to the slide bar 104, and the right side of the trigger plate 105 is an inclined surface. When the slide bar 104 moves to the left and contacts the inclined surface of the trigger plate 105, the trigger plate 105 can drive the slide bar 104 to move upward.

[0033] First, place the alloy rod between the upper and lower arc-shaped plates 5, and make one end of the alloy rod be in the electric rotating disk 4, and then use a tool to twist the bidirectional screw 8 to rotate forward to drive the upper and lower one-dimensional hole plates 7 to move inward, and the upper and lower one-dimensional hole plates 7 move inward to drive the upper and lower positioning frames 6 to move inward, and the upper and lower positioning frames 6 move inward to contact the alloy rod, and drive the alloy rod to move to the center position to complete the positioning, and the center point of the end of the alloy rod corresponds to the center position of the tailstock 2. Stop twisting the bidirectional screw 8 to reverse, and the upper and lower positioning frames 6 stop moving inward, then the machine tool 1 can be operated to drive the movable seat 3 to move to the left, and the movable seat 3 moves to the left to drive the slide bar 104 and the electric rotating disk 4 to move to the left, and the slide bar 104 moves to the left and contacts the inclined surface of the trigger plate 105, the trigger plate 105 drives the slide bar 104 to move upward, the slide bar 104 moves upward and drives the movable plate 106 to move to the left, the connecting spring 107 is compressed, the movable plate 106 moves to the left and drives the disc 103 to move to the left, the disc 103 moves to the left and drives the elastic telescopic frame 102 to move to the left, the elastic telescopic frame 102 moves to the left and drives the trigger ring 101 to move to the left, the trigger ring 101 moves to the left and drives the elastic clamping rod 10 to move inward and contact the alloy rod, the elastic clamping rod 10 also clamps the alloy rod, and due to the setting of the elastic clamping rod 10, alloy rods of different sizes can be clamped and fixed, the elastic clamping rod 10 clamps the alloy rod After being fixed, it stops moving inward, the elastic clamping rod 10 limits the elastic telescopic frame 102 through the trigger ring 101, the disc 103 continues to move to the left to compress the elastic telescopic frame 102, the sliding rod 104 continues to move to the left and disengages from the inclined surface of the trigger plate 105, and the sliding rod 104 stops moving upward. At the same time, the movable seat 3 also drives the fixed frame 9 to move to the left, and the fixed frame 9 drives the arc plate 5 to move to the left through the U-shaped plate 91, and the arc plate 5 drives the alloy rod to move to the left through the positioning frame 6. The alloy rod and the electric rotating disk 4 move to the left synchronously, and the electric rotating disk 4 is started to drive the elastic clamping rod 10 to rotate, and the rotation of the elastic clamping rod 10 drives the alloy rod to rotate, and the alloy rod moves to the left and rotates to contact the tip of the tail end. At this time, the tip of the tailstock 2 will drill into the alloy rod. Since the alloy rod has been positioned, the tailstock 2 will not draw a circle at the end of the alloy rod, and the precise positioning is completed. The machine tool 1 stops driving the movable seat 3 to move to the left, and the alloy rod stops moving to the left. Then the bidirectional screw 8 is reversed to drive the upper and lower side slotted hole plates 7 to move outward and reset. The positioning frame 6 also moves outward and resets to release the alloy rod, and the U-shaped plate 91 is pushed to drive the arc plate 5 to move backward. The arc plate 5 drives the positioning frame 6 to move backward to a suitable position, and then the subsequent processing of the precisely positioned alloy rod can be started. In this way, the alloy rod can be positioned quickly and accurately to prevent deviations, thereby improving positioning efficiency.When the alloy rod is processed, the electric rotating disk 4 is turned off, and the machine tool 1 is operated to drive the movable seat 3 to move to the right and reset. The elastic clamping rod 10 also drives the alloy rod to move to the right and reset, and the movable seat 3 also drives the sliding rod 104 to move to the right and disengage from the trigger plate 105. Due to the action of the connecting spring 107, the movable plate 106 moves to the right and resets, and drives the elastic telescopic frame 102 to move to the right and reset through the disc 103. The elastic telescopic frame 102 drives the trigger ring 101 to reset, and the elastic clamping rod 10 also moves outward and resets to release the alloy rod, so that the alloy rod can be removed.

The piston rods of the single-rod hydraulic cylinders Ⅱ112 on the left and right sides are in contact with the inclined surfaces of the ratchet 113 on the left and right sides respectively. When the piston rod of the single-rod hydraulic cylinder Ⅱ112 moves, the movement of the piston rod of the single-rod hydraulic cylinder Ⅱ112 can drive the ratchet 113 to move. The front sides of the single-rod hydraulic cylinders Ⅱ112 on the left and right sides are connected with a hose 111. The single-rod hydraulic cylinder Ⅰ11 is fixedly connected to the upper rear side of the right side of the movable seat 3. The left rear side of the single-rod hydraulic cylinder Ⅰ11 is fixedly connected and connected to the tail end of the hose 111.

[0035] See also Figure 8As shown, it also includes a material blocking component installed between the machine tool 1 and the movable seat 3, the material blocking component includes a discharge frame 12, a shell 121, a rotating shaft 122, a spiral spring II 123, a blocking cloth 124 and a trigger member. The discharge frame 12 is fixedly connected to the upper left side of the rear side of the machine tool 1, and the discharge frame 12 can discharge the debris. The shell 121 is fixedly connected to the middle of the left part of the movable seat 3, and the rotating shaft 122 is rotatably connected between the middle parts of the front and rear sides of the shell 121. A blocking cloth 124 is wound around the rotating shaft 122. The blocking cloth 124 is inclined, and the tail end of the blocking cloth 124 slides through the left side of the shell 121 and is fixedly connected to the upper right part of the discharge frame 12. When the debris falls, the blocking cloth 1 24 can block the debris, and rubber strips are arranged on the edges of the front and rear sides of the blocking cloth 124. The front and rear sides of the rotating shaft 122 are respectively connected with the front and rear side surfaces in the shell 121 with a spiral spring II 123. A triggering member is arranged between the movable seat 3 and the electric rotating disk 4. When the triggering member rotates, the triggering member can vibrate the blocking cloth 124. The triggering member is a push rod 125, and the push rod 125 is rotatably connected to the middle part of the left side of the movable seat 3. When the push rod 125 rotates and contacts with the blocking cloth 124, the push rod 125 can drive the blocking cloth 124 to move downward for vibration. The middle part of the push rod 125 and the central axis of the electric rotating disk 4 are driven by a synchronous belt assembly.

[0036] Initially, the reset spring Ⅰ116 is in a stretched state. When the operator twists the bidirectional screw 8 to rotate forward to drive the up and down moving slotted orifice plate 7 to move inward, the bidirectional screw 8 rotates forward to reel in the volute spring Ⅰ115, and the bidirectional screw 8 also drives the ratchet 114 to rotate forward and spin on the ratchet bar 113. Then, after the positioning frame 6 clamps the alloy bar in place, the twisting of the bidirectional screw 8 to rotate forward is stopped. The bidirectional screw 8 stops driving the ratchet 114 to rotate forward, and the machine tool 1 can be operated to drive the movable seat 3 to move left, which also causes the alloy bar to move left. When the alloy bar moves left, it first contacts the piston rod of the single-rod hydraulic cylinder Ⅰ11, and the alloy bar drives the piston rod of the single-rod hydraulic cylinder Ⅰ11 to move left. The liquid is pushed into the hose 111, and the liquid in the hose 111 is discharged into the single-rod hydraulic cylinder II 112. As the liquid is discharged, the piston rod of the single-rod hydraulic cylinder II 112 moves backward, driving the ratchet 113 to move outward, and the reset spring II 117 is compressed, and the ratchet 113 moves outward and disengages from the ratchet 114. Due to the action of the volute spring I 115, the bidirectional screw 8 reverses and drives the upper and lower side slotted orifice plates 7 to move outward and reset, which also causes the positioning frame 6 to move outward and reset and disengage from the alloy rod. Due to the action of the reset spring I 116, the U-shaped plate 91 is driven to move backward and the arc plate 5 is driven to move outward, which also causes the positioning frame 6 to move backward to a suitable position without affecting the processing of the alloy rod. When the alloy bar is processed, the alloy bar moves to the right and disengages from the tailstock 2, and the alloy bar also disengages from the piston rod of the single-rod hydraulic cylinder Ⅰ11. Due to the action of the reset spring Ⅱ117, the ratchet 113 moves inward and resets, driving the piston rod of the single-rod hydraulic cylinder Ⅱ112 to move forward and reset, so that the liquid in the single-rod hydraulic cylinder Ⅱ112 is discharged back to the single-rod hydraulic cylinder Ⅰ11 through the hose 111. As the liquid is discharged, the piston rod of the single-rod hydraulic cylinder Ⅰ11 moves to the right and resets. After the processed alloy bar is removed, the U-shaped plate 91 is pulled forward and reset, the reset spring Ⅰ116 is stretched, and the bidirectional screw 8 moves forward and resets, driving the ratchet 114 to move forward and reset, and the ratchet 114 moves forward and resets and meshes with the ratchet 113 again. In this way, there is no need to manually make the positioning frame 6 loosen the alloy bar and move it backward to a suitable position, thereby further improving work efficiency.

[0037] Initially, the volute spring II 123 is in a compressed state. When the movable seat 3 moves to the left, the movable seat 3 also drives the shell 121 to move to the left. The shell 121 moves to the left and drives the shaft 122 to move to the left. The shaft 122 moves to the left and drives the cloth 124 to move to the left to relax. Due to the action of the volute spring II 123, the shaft 122 rotates forward to reel in the relaxed cloth 124. Then, when the movable seat 3 stops moving to the left, the movable seat 3 stops driving the shell 121 to move to the left, and the cloth 124 also stops relaxing. When the electric rotating disk 4 rotates, the electric rotating disk 4 rotates and drives the push rod 125 to rotate through the synchronous belt assembly. The push rod 125 rotates with the cloth 1 24, the push rod 125 drives the blocking cloth 124 to move downward. When the push rod 125 continues to rotate and disengages from the blocking cloth 124, the blocking cloth 124 moves upward to reset, and this is repeated, so that the blocking cloth 124 can continuously move up and down to vibrate, and then when the alloy bar is being processed, the debris generated during the processing falls onto the blocking cloth 124, and the up and down movement of the blocking cloth 124 also vibrates the debris, and the debris after the vibration falls into the discharge frame 12, and the collection container can be placed under the discharge port of the discharge frame 12, and the discharge frame 12 discharges the debris into the collection container. Because the edge of the blocking cloth 124 is provided with a rubber strip, the debris can be prevented from falling from the blocking cloth 124. When the alloy bar is processed, the electric rotating disk 4 stops rotating, the push rod 125 also stops rotating, the blocking cloth 124 stops moving up and down, the movable seat 3 moves to the right to drive the housing 121 to move to the right, so that the rotating shaft 122 moves to the right to reverse and release the blocking cloth 124, and the spiral spring II 123 is compressed. In this way, it can prevent the debris generated during the processing from falling onto the machine tool 1 and affecting the movement of the movable seat 3, thereby ensuring the smooth movement of the movable seat 3.

[0038] See also Fig. 9 As shown, a rubber pad 13 is also included. The rubber pad 13 is fixedly connected to the middle of the right side surface of the electric rotating disk 4. When the end of the alloy rod contacts the rubber pad 13, the rubber pad 13 can protect the alloy rod.

[0039] See also Fig. 9 As shown, a force-bearing rod 14 is also included. The rear side of the top of the upper U-shaped plate 91 is fixedly connected with the force-bearing rod 14, and the force-bearing rod 14 can drive the U-shaped plate 91 to move.

[0040] When the end of the alloy bar moves into the electric rotating disk 4, the end of the alloy bar contacts the rubber pad 13, and the rubber pad 13 protects the alloy bar. In this way, the end of the alloy bar can be prevented from rubbing against the electric rotating disk 4 to cause wear, thereby ensuring the integrity of the alloy bar.

[0041] When the U-shaped plate 91 needs to be pulled forward to reset, the force rod 14 can be held to drive the U-shaped plate 91 to move forward. The force rod 14 provides a force point for the operator, so that the U-shaped plate 91 can be pulled more conveniently to move.
