[0025] The first screw rod 31 of the adjusting mechanism 3 is rotationally connected to the inside of the sliding groove 2, the inner end of the first screw rod 31 is fixedly connected with the first bevel gear 32, the first bevel gear 32 is in transmission connection with the driving mechanism 4, the outer surface of the first screw rod 31 is threadedly connected with the sliding block 33, and the sliding block 33 is connected with the clamping mechanism 5. During use, when the driving mechanism 4 is started, the driving mechanism 4 drives the first bevel gear 32 in transmission connection to rotate, because the first bevel gear 32 is fixedly connected to the inner end of the first screw rod 31, the rotation of the first bevel gear 32 can synchronously drive the first screw rod 31 to rotate in the sliding groove 2. Because the outer surface of the first screw rod 31 is threadedly connected with the sliding block 33, along with the rotation of the first screw rod 31, the sliding block 33 will displace along the sliding groove 2. The sliding block 33 is connected with the clamping mechanism 5, and the displacement of the sliding block 33 will drive the clamping mechanism 5 to act. At the same time, the displacement mechanisms 6 at the top of both sides of the base disc 1 are interconnected with the clamping mechanism 5, when it is necessary to adjust the position or state of the clamping mechanism 5, the displacement mechanisms 6 are operated, the clamping mechanism 5 is further adjusted through the interconnection with the clamping mechanism 5, in the whole process, the sliding grooves 2 arranged in a ring shape on the base disc 1 provide installation and running tracks for the adjusting mechanism 3, the stable work of the adjusting mechanism 3 is guaranteed, thereby the one-way locking of the workpiece and the flexible adjustment of the locking state according to different requirements are realized.

When the sliding block 33 in the adjusting mechanism 3 moves in the sliding groove 2, the base plate 51 fixedly connected to the top of the sliding block 33 moves, the movement of the base plate 51 drives the sleeve 52 installed on the top of the base plate 51 to move synchronously. Since the sliding rod 53 is slidingly connected to the inner side of the sleeve 52, the displacement of the sleeve 52 causes the sliding rod 53 to move correspondingly. The sliding rod 53 and the sleeve 52 are both fixedly provided with the clamping plate 54 on the inner side upper end. With the change of the relative position of the sliding rod 53 and the sleeve 52, the distance between the two clamping plates 54 changes. When the workpiece is clamped, the workpiece is placed between the two clamping plates 54. With the approach of the clamping plates 54, the anti-skid plate 56 fixedly installed in the clamping groove 55 contacts the workpiece. The anti-skid plate 56 increases the friction between the workpiece, so that the clamping plate 54 can stably fix the workpiece in the clamping groove 55, realizing the one-way locking of the workpiece, ensuring that the workpiece remains stable during the machining process and preventing displacement or loosening.

[0027] Reference Figures 2-4The driving mechanism 4 comprises a fixing frame 41 fixedly connected to the bottom of the base disc 1, a first motor 42 fixedly installed at the bottom of the fixing frame 41, a second bevel gear 43 fixedly connected to the output end of the first motor 42 and penetrating through the fixing frame 41, the top of the second bevel gear 43 and the first bevel gear 32 being in meshing connection, a synchronous wheel 44 and a side arm 45, the side arm 45 being fixedly connected to one side of the bottom of the base disc 1, the synchronous wheel 44 being rotatably connected to both sides of the bottom of the base disc 1 and being in driving connection through a synchronous belt 47, the second motor 46 being fixedly connected to the bottom of the side arm 45, the output end of the second motor 46 being connected to the bottom of the synchronous wheel 44, the top of the synchronous wheel 44 being connected to the displacement mechanism 6, and the working of the driving mechanism 4 being based on the cooperative operation of the two motors, the first motor 42 being installed at the bottom of the fixing frame 41, the fixing frame 41 being connected to the bottom of the base disc 1, when the first motor 42 is started, the output end of the first motor 42 drives the second bevel gear 43 to rotate, the second bevel gear 43 is in meshing connection with the first bevel gear 32, thereby driving the first bevel gear 32 to rotate, the rotation of the first bevel gear 32 drives the first lead screw 31 connected thereto to rotate, the driving of the adjusting mechanism 3 is realized, and finally the clamping mechanism 5 is driven to clamp the workpiece, at the same time, the second motor 46 is fixedly connected to the bottom of the side arm 45, the side arm 45 is connected to one side of the bottom of the base disc 1, after the second motor 46 is started, the output end of the second motor 46 drives the synchronous wheel 44 to rotate, the two synchronous wheels 44 are in driving connection through the synchronous belt 47, the synchronous rotation is ensured, the rotation of the synchronous wheel 44 transmits power to the displacement mechanism 6, thereby driving the displacement mechanism 6, and through the linkage of the displacement mechanism 6 and the clamping mechanism 5, the position or state of the clamping mechanism 5 is adjusted, different machining requirements are met.

[0028] Reference Figures 2-3The displacement mechanism 6 comprises an upright rail 61 fixedly connected to the top of the base disc 1, a second lead screw 62 rotatably connected inside the upright rail 61, a movable block 63 threadedly connected to the outer surface of the second lead screw 62, the movable block 63 being slidably connected to the inside of the upright rail 61, a fixed arm 64 fixedly connected to the outer side of the movable block 63, a push ring 65 fixedly connected to the top of the fixed arm 64, a connecting rod 66 slidably connected to the push ring 65 in a ring shape at equal intervals, the outer end of the connecting rod 66 penetrating through the push ring 65, and the inner end of the connecting rod 66 and the outer side upper end of the sliding rod 53 being fixedly connected, and the top of the synchronous wheel 44 and the bottom of the second lead screw 62 being connected. When the second motor 46 in the driving mechanism 4 is started, the synchronous wheel 44 is driven to rotate. Since the top of the synchronous wheel 44 is connected to the bottom of the second lead screw 62, the rotation of the synchronous wheel 44 drives the second lead screw 62 to rotate inside the upright rail 61. The outer surface of the second lead screw 62 is threadedly connected to the movable block 63. With the rotation of the second lead screw 62, the movable block 63 slides up and down in a straight line along the lead screw inside the upright rail 61. The fixed arm 64 fixedly connected to the outer side of the movable block 63 moves with the movement of the movable block 63. The push ring 65 at the top of the fixed arm 64 also moves up and down. The connecting rod 66 slidably connected to the push ring 65 in a ring shape has its outer end penetrating through the push ring 65 and its inner end fixedly connected to the outer side upper end of the sliding rod 53. When the push ring 65 moves up and down, the sliding rod 53 is pushed to slide in the sleeve 52 through the connecting rod 66, the relative position of the sliding rod 53 and the sleeve 52 is changed, and the clamping range and state of the clamping mechanism 5 are adjusted to adapt to the clamping needs of workpieces of different lengths.

[0029] Reference Figures 1-4 The bottom of the base disc 1 is fixedly provided with mounting arms 7, and the outer end of the mounting arm 7 is provided with a mounting hole 8. The mounting hole 8 is a countersunk hole. The mounting arms 7 at the bottom of the base disc 1 mainly serve to connect and fix the entire machining center one-way locking device with external equipment. The countersunk hole at the outer end of the mounting arm 7 can make the head of the connecting bolt sink into the hole and flush with the surface of the mounting arm 7, so as to avoid the protruding connecting bolt affecting the overall structural stability of the device and the normal operation of other components. During installation, the bolt is passed through the countersunk hole and connected with the corresponding threaded hole on the external equipment. By tightening the bolt, the mounting arm 7 is tightly attached to the external equipment, and then the entire one-way locking device is firmly installed at the specified position, so as to ensure that the device will not be displaced or loosened during work due to external force, and ensure its stable operation, providing a solid foundation for subsequent workpiece clamping and machining operations.

[0030] Working principle and advantages: the device combines the driving mechanism 4 with the clamping mechanism 5, which significantly improves the workpiece clamping performance during processing. When the device is running, start the first motor 42. The power generated by the motor operation drives the second bevel gear 43 to rotate. Since the second bevel gear 43 is in meshing connection with the first bevel gear 32, the first bevel gear 32 rotates under the drive of the second bevel gear 43. The rotation of the first bevel gear 32 further synchronously drives the four first lead screws 31 to rotate simultaneously. With the rotation of the first lead screw 31, the sliding block 33 cooperated with it stably slides in the inner side of the sliding groove 2. The synchronous sliding of the sliding block 33 further drives the sleeve 52 and the slide rod 53 in the clamping mechanism 5 to displace, finally realizing the stable clamping and positioning of the clamping plate 54 to different size workpieces.

[0031] The four sets of clamping plates 54 play a key role in the process of mutual displacement. The anti-skid plate 56 arranged in the inner clamping groove 55 increases the friction between the workpiece and the clamping plate 54, so that it can more stably clamp workpieces of various sizes. This design greatly improves the convenience of the device in actual use, enabling it to quickly and accurately adapt to diversified workpiece clamping needs, significantly enhancing the adaptability of the device and providing a solid guarantee for efficient and accurate processing.

[0032] The device cooperates the displacement mechanism 6 with the driving mechanism 4 to realize flexible clamping and adaptation to workpieces of different lengths. When the device needs to adjust the sliding of the sleeve 52 and the slide rod 53, start the second motor 46. After the second motor 46 operates, the synchronous pulley 44 at its output end rotates. Since the synchronous pulleys 44 are transmission connected by the synchronous belt 47, the rotation of one synchronous pulley 44 can synchronously drive the second lead screw 62 inside the vertical rail 61 to rotate. The rotation of the second lead screw 62 drives the movable block 63 to stably slide up and down inside the vertical rail 61 through thread cooperation.

[0033] The sliding of the movable block 63 drives the fixed arm 64 to displace, and then the push ring 65 at the front end of the fixed arm 64 realizes up and down movement. The up and down displacement of the push ring 65 can flexibly adjust the relative sliding of the connecting rod 66, the slide rod 53 and the sleeve 52, thereby realizing effective adjustment of the extension length of the slide rod 53 and the sleeve 52. This design enables the device to accurately clamp workpieces of different lengths and meet diversified processing needs. In addition, during clamping, the connecting rod 66 and the push ring 65 are connected in a sliding manner. This connection enables the connecting rod 66 to maintain reciprocating clamping function through its sliding during length adjustment, effectively improving the clamping and adaptation performance of the device during overall use, greatly facilitating the operation and application of the device in actual production, and providing strong support for improving processing efficiency and processing precision.
