TECHNICAL FIELD

[0001] The present application relates to the technical field of metal shaft clamps, in particular to a groove cylinder shaft positioning tool clamp. BACKGROUND

[0002] A lathe is a machine tool that utilizes the rotation of a workpiece and the linear feed motion of a cutting tool to machine the workpiece. The clamps used in ordinary lathes are generally three-jaw or four-jaw chucks. The chuck rotates with the main shaft of the lathe, and the workpiece is fixed by the jaws and rotates with the chuck. The principle of clamping the workpiece by the chuck of the lathe is that multiple jaws provide sufficient clamping force along the radial direction of the workpiece. The surface of the general jaw has a thread that increases friction, and the resulting friction prevents the workpiece from moving or becoming eccentric during machining.

[0003] Among them, after the clamp completes the clamping of the groove cylinder shaft, the clamp drives the groove cylinder shaft to rotate at a constant speed, and the tool of the machine tool cuts the groove of the groove cylinder shaft. The resistance of the above cutting is in a relatively stable area. When the machine tool appears the punch phenomenon, the tool contacts the new area of the groove cylinder shaft, which causes the machining resistance of the two to increase sharply, and finally the tool is damaged and the workpiece is broken. To solve the above problems, the following scheme is proposed. SUMMARY

[0009] Preferably, the fixing mechanism comprises:

[0010] The accumulation assembly is fixedly connected to the inner wall of the chuck;

[0011] The pushing assembly is slidingly connected to the inner wall of the accumulation assembly;

[0012] When the threaded disc rotates in the inner wall of the chuck, the accumulation assembly is deformed under pressure and accumulates potential energy.

[0013] Preferably, the positioning mechanism comprises:

[0014] The buckle assembly is slidingly connected to the side wall of the accumulation assembly.

[0015] The limiting assembly is fixedly connected to the side wall of the chuck.

[0016] When the bevel gear disc drives the threaded disc to rotate, the buckle assembly will fit the outer wall of the bevel gear disc and limit the rotation of the bevel gear disc to a single direction.

[0017] Preferably, the power mechanism comprises:

[0018] The rotating assembly is fixedly connected to the side wall of the chuck.

[0019] The driving assembly is rotatably connected to the side wall of the rotating assembly.

[0020] The driving assembly is fixedly connected to the external device to fix the device and provide rotating power.

[0021] Preferably, the accumulation assembly comprises a torsion spring fixedly connected to the inner wall of the chuck, one end of the torsion spring away from the chuck is fixedly connected to the inner wall of the threaded disc, and four sliding grooves are formed in the inner wall of the chuck.

[0022] When the threaded disc rotates in the inner wall of the chuck, the torsion spring is deformed under pressure and accumulates potential energy.

[0023] Preferably, the pushing assembly comprises a fixed disc fixedly connected to the side wall of the sliding column, a spring is fixedly connected to the side wall of the fixed disc, and one end of the spring away from the fixed disc is fixedly connected to the inner wall of the chuck.

[0024] Under normal circumstances, the spring is in a state of being pulled and always generates a shrinking pulling force.

[0025] Preferably, the buckle assembly comprises a contact block slidingly connected to the inner wall of the fixed disc, an inclined surface is formed in the side wall of the contact block, a fitting surface is formed in the side wall of the contact block, and a spring sheet is fixedly connected to the bottom of the contact block.

[0026] When the threaded disc rotates forward, the teeth of the bevel gear disc are in contact with the outer wall of the bevel, and the contact block is forced to slide downward along the inner wall of the fixed disc, and the elastic sheet is deformed to accumulate potential energy.

[0027] Preferably, the limiting assembly comprises a sliding groove two opened at the side wall of the chuck, a sliding plate one is slidingly connected to the inner wall of the sliding groove two, a spring two is fixedly connected to the side wall of the sliding plate one, an arc-shaped plate is fixedly connected to the end of the spring two away from the sliding plate one, the outer wall of the arc-shaped plate is slidingly connected to the inner wall of the sliding groove two, and a bevel one is opened at the side wall of the arc-shaped plate.

[0028] During use, the spring two is always in a compressed state and always generates an outward pushing force to force the arc-shaped plate to push outward.

[0029] Preferably, the rotating assembly comprises a sliding plate two fixedly connected to the side wall of the chuck, the sliding plate two is slidingly connected to the inner wall of the inclined plate two, a fixed block is fixedly connected to the side wall of the inclined plate two, a screw is rotatably connected to the side wall of the sliding plate one, a nut is fixedly connected to the side wall of the chuck, and the outer wall of the screw is threadedly connected to the inner wall of the nut.

[0030] In the normal state, the side wall of the inclined plate two is in contact with the side wall of the sliding column to limit the sliding of the sliding column along the inner wall of the sliding groove one. When the clamp bears too much resistance, the arc-shaped plate limits the rotation of the inclined plate two. When the rotating resistance of the device is small, the rotating pressure of the driving assembly is transmitted to the arc-shaped plate through the rotating assembly, the arc-shaped plate drives the chuck to rotate. When the rotating resistance is too large, the inclined plate two is rotated by the fitting of the bevel one and the inclined surface of the side wall of the inclined plate two, the pressure of the rotating inclined plate two forces the arc-shaped plate to slide inward along the inner wall of the sliding groove two, and finally the inclined plate two slides along the inner wall of the sliding plate two to the position of the outer wall of the arc-shaped plate, and the restriction of the inclined plate two to the sliding column is removed. The spring one drives the sliding column to slide downward along the inner wall of the sliding groove one, and the restriction of the buckle assembly to the bevel gear disc is removed.

[0031] Preferably, the driving assembly comprises a rotating ring rotatably connected to the outer wall of the sliding plate two, a driving column is fixedly connected to the side wall of the rotating ring, a fixed frame is rotatably connected to the side wall of the driving column, and the side wall of the rotating ring is fixedly connected to the side wall of the fixed block.

[0032] Wherein, before using, the fixed frame needs to be fixedly connected to the inner wall of the machine tool, and the rotating force of the external driving shaft can be transmitted to the driving column, when the driving column drives the rotating ring to rotate counterclockwise, the rotating ring drives the inclined plate two to impact the side wall of the arc plate along the inner wall of the sliding plate two, when the rotating ring drives the fixed block to rotate clockwise, the rotating ring drives the inclined plate two to slide along the inner wall of the sliding plate two, and directly releases the restriction of the inclined plate two on the sliding column.

[0033] The present application has the following advantages:

[0034] (1) The present application is aimed at the problem that when the punching machine phenomenon occurs during the machining of the groove cylinder shaft, the resistance between the groove cylinder shaft and the tool increases, and finally the tool is damaged. A positioning mechanism and a power mechanism are arranged in the equipment. The rotating force of the external driving shaft is transmitted to the rotating ring through the driving column, and the rotating ring drives the inclined plate two to slide along the inner wall of the sliding plate two through the fixed block. However, due to the restriction of the arc plate, the arc plate drives the chuck to rotate in the same direction. When the punching machine phenomenon occurs in the machine tool, the resistance between the tool and the groove cylinder shaft will be converted into the counter-pressure of the inclined plate two and the arc plate, such as Figure 12 the inclined surface one position, the inclined surface of the inclined plate two will contact the inclined surface one, when the extrusion resistance is greater than the pressure of the arc plate restricting the sliding of the inclined plate two, the arc plate will be pressed to slide downward along the inner wall of the sliding groove two, so that the inclined plate two slides along the inner wall of the sliding plate two, away from the original position, and at the same time, the restriction of the inclined plate two on the sliding column is released. The spring one drives the sliding column to slide downward along the sliding groove one inner wall and contacts the buckle assembly to restrict the inclined surface gear disc. At this time, the torsional spring will release potential energy and drive the threaded disc to rotate and reset. The threaded disc will force the three sliding clamps to quickly move away from each other. Through the application of the above-mentioned components, when the equipment appears the punching machine phenomenon, the sliding clamps quickly loosen the clamping of the groove cylinder shaft, reducing the damage degree of the groove cylinder shaft to the tool.

[0035] (2) When the external equipment drives the chuck to rotate quickly, the torsional spring will drive the inclined surface gear disc to have a tendency to slide back. At this time, the contact surface will be in contact with the inner wall of the inclined surface gear disc and limit the rotation of the inclined surface gear disc. Through the application of the above-mentioned components, it is prevented that when the chuck rotates quickly, the threaded disc rotates due to rotation, resulting in a decrease in the clamping force of the sliding clamp on the groove cylinder shaft.

[0036] (3) The present application utilizes the characteristics of the above-mentioned contact block to limit the inclined surface gear disc. Four fixed discs are unevenly distributed inside the chuck, and five contact blocks are unevenly distributed on the top of the four fixed discs. Each contact block is in contact with the inclined surface gear disc. However, due to the uneven distribution of each contact block, there are differences in the contact state between most of the contact blocks and the inclined surface gear disc, such as Figure 7The state of the contact block is different from the state of the middle G, and the contact block with different state will effectively limit the bevel gear plate during the rotation of the bevel gear plate. Through the application of the above components, the large width of the tooth groove of the bevel gear plate is prevented, so that the self-rotation of the thread plate occurs when the chuck rotates;

[0037] (4) The staff can drive the sliding plate one to slide upward along the inner wall of the sliding groove two by twisting the screw. Since the outer wall of the arc-shaped plate is limited by the inner wall of the sliding plate two, when the sliding plate one approaches the arc-shaped plate, the pressure of the spring two will be increased, and the potential energy of the spring two will be increased. The resistance of the arc-shaped plate to slide along the inner wall of the sliding groove two to the sliding plate one will be increased. Through the application of the above components, the device can change the outward thrust of the spring two according to the contact force of the tool and the groove cylinder shaft, so that the device can adapt to the machining efficiency of grooves with different depths.

[0071] Embodiment two, please refer to Figure 4 - Figure 12 The present application is a groove cylinder shaft positioning tool clamp, based on example one, the accumulation assembly 11 comprises a torsion spring 111 fixedly connected at the inner wall of the chuck 13, the end of the torsion spring 111 away from the chuck 13 is fixedly connected with the inner wall of the threaded disc 15, four sliding grooves one 112 are arranged at the inner wall of the chuck 13, and the sliding column 113 is slidingly connected at the inner wall of the four sliding grooves one 112.

[0072] Wherein, when the threaded disc 15 rotates in the inner wall of the chuck 13, the torsion spring 111 will be compressed to generate deformation and accumulate potential energy.

[0073] The pushing assembly 12 comprises a fixed disc 121 fixedly connected at the side wall of the sliding column 113, a spring I 122 fixedly connected at the side wall of the fixed disc 121, and the end of the spring I 122 away from the fixed disc 121 fixedly connected with the inner wall of the chuck 13.

[0074] Wherein, in the normal state, the spring I 122 is in a state of being pulled, and always generates a shrinking pulling force.

[0075] The buckle assembly 21 comprises a contact block 211 slidingly connected at the inner wall of the fixed disc 121, a bevel 212 formed at the side wall of the contact block 211, a fitting surface 213 formed at the side wall of the contact block 211, and a spring sheet 214 fixedly connected at the bottom of the contact block 211.

[0076] Wherein, by using the above-mentioned characteristics of the contact block 211 limiting the bevel tooth disc 16, four fixed discs 121 are unevenly distributed inside the chuck 13, and five contact blocks 211 are unevenly distributed at the top of the four fixed discs 121, and each contact block 211 is fitted with the bevel tooth disc 16, but due to the uneven distribution of each contact block 211, the contact state of most of the contact blocks 211 with the bevel tooth disc 16 is different, showing the state of Figure 7 Wherein, the contact blocks 211 in different states will effectively buckle and limit the bevel tooth disc 16 during the rotation of the bevel tooth disc 16, and by using the above-mentioned assembly, it is prevented that the large width of the tooth groove of the bevel tooth disc 16 causes the threaded disc 15 to rotate when the chuck 13 rotates.

[0077] The limiting assembly 22 comprises a sliding groove two 221 formed at the side wall of the chuck 13, a sliding plate one 222 slidingly connected at the inner wall of the sliding groove two 221, a spring two 223 fixedly connected at the side wall of the sliding plate one 222, an arc-shaped plate 224 fixedly connected at the end of the spring two 223 away from the sliding plate one 222, and the outer wall of the arc-shaped plate 224 slidingly connected with the inner wall of the sliding groove two 221, and a bevel one 225 formed at the side wall of the arc-shaped plate 224.

[0078] Wherein, when the chuck 13 is rapidly rotated by the external device, the torsion spring 111 will drive the bevel tooth disc 16 to have a tendency of resetting sliding, at this time, the fitting surface 213 will be fitted with the inner wall of the bevel tooth disc 16 and limit the rotation of the bevel tooth disc 16, and by using the above-mentioned assembly, it is prevented that the threaded disc 15 rotates due to rotation when the chuck 13 rapidly rotates, resulting in the decrease of the clamping force of the sliding clamp jaw 14 on the groove cylinder shaft.

[0079] The rotating assembly 31 comprises a sliding plate two 311 fixedly connected at the side wall of the chuck 13, an inner wall of the sliding plate two 311 is slidingly connected to an inclined plate two 312, a side wall of the inclined plate two 312 is fixedly connected with a fixed block 313, a side wall of the sliding plate one 222 is rotatably connected with a screw 314, a side wall of the chuck 13 is fixedly connected with a nut 315, and an outer wall of the screw 314 is threadedly connected with an inner wall of the nut 315;

[0080] Wherein, the worker can drive the sliding plate one 222 to slide upwards along the inner wall of the sliding groove two 221 by twisting the screw 314, and since the outer wall of the arc-shaped plate 224 is limited by the inner wall of the sliding plate two 311, when the sliding plate one 222 approaches the arc-shaped plate 224, the pressure on the spring two 223 will be increased, and the potential energy generated by the spring two 223 will be increased, which will increase the resistance of the arc-shaped plate 224 to slide along the inner wall of the sliding groove two 221 towards the sliding plate one 222. Through the application of the above-mentioned assembly, the device can change the outward thrust of the spring two 223 according to the contact force between the tool and the groove shaft, so that the device can adapt to the machining efficiency of grooves with different depths.

[0081] The driving assembly 32 comprises a rotating ring 321 rotatably connected at the outer wall of the sliding plate two 311, a driving column 322 fixedly connected at the side wall of the rotating ring 321, a fixed frame 323 rotatably connected at the side wall of the driving column 322, and the side wall of the rotating ring 321 is fixedly connected with the side wall of the fixed block 313;

[0082] Wherein, in the process of machining the groove shaft by the machine tool, when the punch phenomenon occurs, the resistance between the groove shaft and the tool will increase, and finally the tool will be damaged. In the device, a positioning mechanism 2 and a power mechanism 3 are arranged, wherein the external rotating force is transmitted to the rotating ring 321 through the driving column 322, and the rotating ring 321 drives the inclined plate two 312 to slide along the inner wall of the sliding plate two 311 through the fixed block 313, but due to the limitation of the arc-shaped plate 224, this makes the arc-shaped plate 224 drive the chuck 13 to rotate in the same direction. When the punch phenomenon occurs in the machine tool, the resistance between the tool and the groove shaft will be converted into the counter-pressure of the inclined plate two 312 and the arc-shaped plate 224, as shown in Figure 12At the position of the inclined surface 225, the inclined surface of the inclined plate 312 will contact the inclined surface 225. When the squeezing resistance is greater than the pressure of the arc plate 224 restricting the sliding of the inclined plate 312, the arc plate 224 will be pressed and slide down along the inner wall of the sliding groove 221, so that the inclined plate 312 slides along the inner wall of the sliding plate 311, away from the original position. At the same time, the restriction of the inclined plate 312 on the sliding column 113 is released. The spring 122 drives the sliding column 113 to slide down along the inner wall of the sliding groove 112 and releases the restriction of the buckle assembly 21 on the inclined gear plate 16. At this time, the torsion spring 111 will release potential energy and drive the threaded plate 15 to rotate and reset. The threaded plate 15 will force the three sliding jaws 14 to quickly move away from each other. Through the application of the above components, when the equipment experiences a punching phenomenon, the sliding jaws 14 quickly release the clamping of the grooved cylinder shaft, reducing the damage of the grooved cylinder shaft to the tool.

[0083] A specific application of this embodiment is as follows: Before using the equipment, the power mechanism 3 is fixed inside the machine tool. Then, the operator rotates the helical gear 17. The helical gear 17 drives the threaded disc 15 to rotate through the helical gear plate 16. Since the outer wall of the threaded disc 15 is threadedly connected to the inner wall of the sliding jaw 14, when the threaded disc 15 rotates, the sliding jaw 14 will move closer to each other along the inner wall of the groove of the chuck 13 and position and clamp the grooved cylinder shaft in the center position, thus completing the basic positioning and clamping process.

[0084] like Figure 5 As shown, when the threaded disc 15 rotates in the forward direction, causing multiple sliding jaws 14 to approach each other, the edge of the tooth groove of the inclined toothed disc 16 will contact the outer wall of the inclined surface 212, and press the contact block 211 to slide downward along the inner wall of the fixed disc 121, and squeeze the spring 214 to generate deformation and accumulate potential energy. When the device completes clamping, the torsion spring 111 releases potential energy under pressure, which will drive the threaded disc 15 to rotate in the reverse direction. At this time, the side wall of part of the contact surface 213 will contact the inner wall of the torsion spring 111 and restrict the reverse rotation of the threaded disc 15.

[0085] To address the issue of increased resistance between the slotted shaft and the cutting tool during the machining process of a slotted shaft, which can lead to tool damage due to a punching phenomenon, a positioning mechanism 2 and a power mechanism 3 are installed inside the equipment. The external rotational force is transmitted to the rotating ring 321 via the drive column 322. The rotating ring 321, through the fixed block 313, drives the inclined plate 312 to slide along the inner wall of the sliding plate 311. However, due to the constraint of the arc plate 224, the arc plate 224 causes the chuck 13 to rotate in the same direction. When a punching phenomenon occurs on the machine tool, the resistance between the cutting tool and the slotted shaft is transformed into a punching pressure between the inclined plate 312 and the arc plate 224. Figure 12When the extrusion resistance is greater than the pressure of the arc-shaped plate 224 limiting the sliding of the inclined plate two 312, the arc-shaped plate 224 will be pressed to slide downward along the inner wall of the sliding groove two 221, so that the inclined plate two 312 slides along the inner wall of the sliding plate two 311 away from the original position, and the restriction of the inclined plate two 312 on the sliding column 113 is released, the spring one 122 drives the sliding column 113 to slide downward along the inner wall of the sliding groove one 112, and the restriction of the buckle assembly 21 on the inclined tooth disc 16 is released, at this time the torsional spring 111 will release potential energy to drive the threaded disc 15 to rotate and reset, and the threaded disc 15 will force the three sliding clamping jaws 14 to quickly move away from each other, through the application of the above-mentioned assembly, when the equipment appears punch phenomenon, the sliding clamping jaw 14 quickly loosens the clamping of the groove cylinder shaft, reducing the damage degree of the groove cylinder shaft to the tool.

[0086] When the chuck 13 is rapidly rotated by the external device, the torsional spring 111 will drive the inclined tooth disc 16 to generate a reset sliding trend, at this time the abutting surface 213 will abut with the inner wall of the inclined tooth disc 16 and limit the rotation of the inclined tooth disc 16, through the application of the above-mentioned assembly, preventing the threaded disc 15 from rotating due to rotation when the chuck 13 is rapidly rotated, resulting in a decrease in the clamping force of the sliding clamping jaw 14 on the groove cylinder shaft.

[0087] By utilizing the feature that the contact block 211 limits the inclined tooth disc 16, four fixed discs 121 are unevenly distributed inside the chuck 13, and five contact blocks 211 are unevenly distributed on the top of the four fixed discs 121, and each contact block 211 abuts with the inclined tooth disc 16, but due to the uneven distribution of the contact blocks 211, most of the contact blocks 211 have different contact states with the inclined tooth disc 16, presenting a state like Figure 7 The contact blocks 211 in different states will effectively buckle and limit the inclined tooth disc 16 during the rotation of the inclined tooth disc 16, through the application of the above-mentioned assembly, preventing the threaded disc 15 from rotating due to rotation when the chuck 13 is rapidly rotated, resulting in a decrease in the clamping force of the sliding clamping jaw 14 on the groove cylinder shaft.
