Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts processing, in particular to a novel clamp. Background Art

[0002] Some parts need to be clamped with pliers before they can be ground, drilled, welded, or processed. Due to the limited clamping force and the lack of a locking safety function, continuous processing will easily cause the clamped parts to gradually loosen due to vibration and torque, resulting in safety accidents where parts are thrown out and injure people. After welding, fixed assemblies will experience large tensile stress, causing displacement, which can easily lead to the final size not meeting the requirements and causing quality accidents. In addition, the overall structure is heavy and the use process is more laborious.

[0003] The force clamps in the existing technology can only adjust the jaws in a single motion when clamping parts, and the efficiency of opening and closing the jaws is low. In addition, there is no anti-loosening function when clamping parts for continuous processing. At the same time, the overall weight is large, and the loosening unloading structure is prone to getting stuck, making the use process more laborious. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside” are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] A new type of clamp, such as Figure 1 、 2 As shown, it includes a tightening bolt 1, a toothed forward and reverse screw 2, a reverse splint 3, a connecting plate 4, a locking link 5, a locking screw 6, and a forward splint 7; the forward splint 7 and the reverse splint 3 are relatively arranged on both sides of the connecting plate 4; the toothed forward and reverse screw 2 crosses and is threadedly arranged in the forward splint 7 and the reverse splint 3, and the toothed forward and reverse screw 2 rotates to drive the forward splint 7 and the reverse splint 3 to open and close; the locking screw 6 cooperates with the thread to rotatably pass through the connecting plate 4, and fixes the locking link 5 on the teeth of the toothed forward and reverse screw 2.

[0022] Specifically, the toothed positive and negative thread screw 2 drives the positive clamping plate 7 and the negative clamping plate 3 at the same time to realize the synchronous opening and closing of the jaws, which greatly improves the efficiency of clamping parts. The teeth of the toothed positive and negative thread screw 2 are fixed by the combination of the locking screw 6 and the locking connecting block 5, which effectively prevents the loosening problem caused by vibration and torsion, not only improving the safety during the processing, but also avoiding dimensional deviation and quality accidents caused by loose parts. The reasonable structural layout realizes the reduction of the overall weight, making it more lightweight and flexible during use, optimizing the design of the unloading structure, reducing the risk of getting stuck, and making operation easier. It is smoother and can adapt to parts of different sizes and shapes by adjusting the rotation direction of the toothed forward and reverse screw 2 and the tightness of the locking screw 6, thereby improving the versatility and adaptability of the clamp. Due to its powerful anti-loosening function and two-way rapid adjustment capability, the clamp can ensure that the parts always maintain a stable position and size during the processing, thereby improving the processing accuracy and product quality. On the basis of the two jaw plates being able to open and close at the same time, the jaws can add force to lock the parts, and have a worm gear self-locking anti-loosening function. The use process is efficient and fast, the overall structure is simple and reasonable, and it is easy to use.

[0023] As a preferred embodiment of the above, Figure 2As shown, the locking screw 6 is vertically arranged in the connecting plate 4 and fixes the connecting plate 4. The locking screw 6 cooperates with the thread to rotatably pass through the connecting plate 4 and support the locking screw 6. The locking screw 6 fixes the locking link 5 on the teeth of the toothed forward and reverse screw 2.

[0024] Specifically, the locking screw 6 is vertically set in the connecting plate 4 and fixed to the connecting plate 4 by a threaded connection, ensuring that the locking screw 6 will not shake or shift when bearing load. When the locking screw 6 is rotated to a certain position, it will support the locking block 5, and the locking block 5 will then transmit the force to the teeth of the toothed forward and reverse screw 2, thereby fixing the position of the toothed forward and reverse screw 2 to prevent it from loosening due to vibration or torsion. The locking screw 6 ensures the stability of the clamp when clamping parts. Even under high load or continuous processing, the locking screw 6 can effectively prevent the toothed forward and reverse screw 2 from loosening, thereby maintaining stable clamping of the parts. The locking screw 6 also makes the locking and loosening operations of the clamp easier. The operator only needs to rotate the locking screw 6 to lock and loosen the clamp without using other tools or performing complicated operations.

[0025] As a preferred embodiment of the above, Figure 1 As shown, the locking screw 6 changes its front and rear position in the connecting plate 4 through the groove.

[0026] Specifically, by allowing the locking screw 6 to move back and forth within the connecting plate 4, the flexibility of the clamp is significantly enhanced. The operator can adjust the position of the locking screw 6 according to the size and shape of the part to ensure that the part is firmly clamped, simplifying the operation of the clamp. The operator only needs to rotate the locking screw 6 to complete the clamping and loosening operations, without the need for other tools or additional steps.

[0027] As a preferred embodiment of the above, Figure 2 As shown, the locking block 5 is L-shaped and is fixed below the locking screw 6 through threads.

[0028] Specifically, the locking block 5 adopts an L-shaped structure, so that the locking block 5 can better cooperate with the teeth of the toothed forward and reverse screw 2, providing stable support and locking force. The locking block 5 is fixed under the locking screw 6 by a thread, which can ensure that the locking block 5 will not loosen or shift when bearing load. Since the locking block 5 is connected by a thread, its position on the locking screw 6 can be easily adjusted to meet the needs of different parts. The locking block 5 with an L-shaped structure can better cooperate with the teeth of the toothed forward and reverse screw 2, providing greater locking force and stability, ensuring that the parts will not loosen due to vibration or torque during processing. The operator only needs to rotate the locking screw 6 to achieve the up and down movement and locking of the locking block 5, without the need to use other tools or perform complicated operations, thereby simplifying the operation process.

[0029] As a preferred embodiment of the above, Figure 1 As shown, locking connecting block matching teeth are provided on the vertical surface of the locking connecting block 5 that is in contact with the teeth of the toothed positive and negative thread screw 2.

[0030] Specifically, the provision of the locking link's mating teeth significantly improves the clamp's locking effect. Due to the tight engagement of the mating teeth, parts are less likely to loosen due to vibration or torsional forces during machining, thereby ensuring machining accuracy and product quality, and enhancing the locking force of the locking link 5 on the toothed forward and reverse threaded screw 2. When the locking screw 6 rotates and pushes the locking link 5 downward, the locking link's mating teeth tightly engage with the teeth of the toothed forward and reverse threaded screw 2, providing greater locking force and stability.

[0031] As a preferred embodiment of the above, Figure 1 As shown, both ends of the toothed screw 2 are provided with hexagonal holes.

[0032] Specifically, the toothed forward and reverse thread screw 2 is provided with a hexagonal hole at each end thereof, so that the toothed forward and reverse thread screw 2 can be tightened with an hexagonal wrench.

[0033] As a preferred embodiment of the above, Figure 1 As shown, the front ends of the orthodontic splint 7 and the anterior splint 3 are respectively tilted inward and fitted together.

[0034] When the workpiece is tightened, the toothed screw 22 is tightened and the workpiece is put into the workpiece, and the toothed screw 22 with the inner hexagonal holes at both ends can be tightened. Then the toothed locking block 4 is slid to the toothed screw 2, and the two teeth are engaged under the grooved anti-up and anti-down locking bolt 6. Finally, the tightening bolt 1 is tightened to support the locking block 4, forming a self-locking and anti-loosening function similar to the worm gear transmission structure with a 90-degree transmission. After clamping, the clamped workpiece can always maintain a large clamping force and anti-loosening self-locking effect under various forces. The overall structure is reasonable and light, and the use safety is good.

[0035] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
