[0001] The utility model relates to the technical field of flat-nose pliers, in particular to an integrated reverse-pull angle-fixed precision flat-nose pliers. Background Art
[0002] Flat-nose pliers are a common clamping tool that is widely used in various machining and manufacturing processes. Its main function is to fix and clamp the workpiece to keep it stable and prevent movement during the machining process.
[0003] At present, there is an integrated reverse-pull angle-fixed precision flat-nose pliers in the prior art. When the traditional angle-fixed flat-nose pliers clamp the workpiece, the front end of the screw is not fixed to the pliers body. When the screw drives the movable body to move for clamping, the movable body will generate thrust and pressure of the principle product. At this time, the screw will generate a backward thrust, and the pliers body will bear the thrust, which can easily lead to deformation of the pliers body and wear of the screw, greatly reducing its service life and poor practicality. Utility Model Content
[0004] The purpose of the utility model is to solve the problem that when the traditional angle-fixed flat-nose pliers in the prior art clamp a workpiece, the front end of the lead screw is not fixed to the pliers body, and when the lead screw drives the movable body to move for clamping, the movable body will generate thrust and pressure of the principle product, and at this time the lead screw will generate a backward thrust, and the pliers body bears the thrust, which easily leads to deformation of the pliers body and wear of the lead screw, greatly reducing its service life, and an integrated reverse-pull angle-fixed precision flat-nose pliers is proposed.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an integrated reverse-angle-fixed precision flat-nose pliers, comprising a pliers body, a first jaw pad is provided in the pliers body, a lead screw is installed in the pliers body, a nut body is threadedly connected to the outer wall of the lead screw, a semi-circular ball is installed on the top of the nut body, the semi-circular ball is connected to a movable body, and a second jaw pad is provided at one end of the movable body.
[0006] Preferably, a nut main body is installed at the top end of the nut auxiliary group guide rail in the pliers body, and the movable body is arranged on the outside of the nut main body.
[0007] Preferably, a semi-circular ball is installed at one end of the nut body, and the movable body is connected to the nut body at a semi-circular angle.
[0008] Preferably, the first jaw pad and the second jaw pad are respectively fixed to the jaw body and the movable body by locking bolts.
[0009] Preferably, a thrust bearing is installed at the front end of the caliper body, the front end of the lead screw is rotatably connected to the thrust bearing, and the other end of the lead screw is connected to the nut body.
[0010] Compared with the prior art, the advantages and positive effects of the utility model are:
[0011] In the utility model, the length of the lead screw is relatively long. When the angle-fixed flat-nose pliers clamp a workpiece, the front end of the lead screw is rotatably connected to the pliers body through the thrust bearing. When the lead screw rotates and drives the movable body to move and clamp, the thrust and pressure generated by the movable body on the lead screw are converted into tensile force by the action of the thrust bearing. The pressure or thrust at the connection at the rear end of the lead screw is converted into the tensile force generated by the front end of the lead screw and the thrust bearing. Therefore, the deformation of the pliers body is small, and the overall accuracy is improved. This device has an angle-fixed design. The semi-circular ball can generate a 30° downward component force during the tightening process to ensure that the workpiece does not float. The first jaw pad and the second jaw pad are respectively fixed to the pliers body and the movable body by locking bolts, thereby reducing the dynamic deformation. The entire device is quenched to maintain long-term wear resistance and accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0018] Embodiment 1, as Figure 1-3As shown, the utility model provides an integrated inverted angle fixed precision flat-nose pliers, including a pliers body 1, a first jaw pad 2 is provided in the pliers body 1, a lead screw 7 is installed in the pliers body 1, a nut body 5 is threadedly connected to the outer wall of the lead screw 7, a semicircular ball 6 is installed on the top of the nut body 5, the semicircular ball 6 is connected to a movable body 3, and a second jaw pad 4 is provided at one end of the movable body 3.
[0019] The effect achieved by the entire embodiment 1 is that, through the rotation of the screw 7, the nut auxiliary guide rail 9 is moved under the limit of the limit cavity opened in the pliers body 1, thereby driving the nut main body 5 to pull the movable body 3 to move in the direction of the first jaw pad 2, and clamping and fixing the workpiece between the second jaw pad 4 and the first jaw pad 2. In this device, the screw 7 and the pliers body 1 bear the tensile force, so the deformation of the pliers body 1 is small, and the overall accuracy is improved.
[0020] Embodiment 2, as Figure 1-3 As shown, a nut main body 5 is installed on the top of a nut auxiliary guide rail 9 in the pliers body 1, a movable body 3 is arranged on the outside of the nut main body 5, a semicircular ball 6 is installed on one end of the nut main body 5, the movable body 3 and the nut main body 5 are connected at an angle with the semicircular ball 6, the first jaw pad 2 and the second jaw pad 4 are respectively fixed to the pliers body 1 and the movable body 3 by locking bolts, a thrust bearing 8 is installed at the front end of the pliers body 1, the front end of the screw 7 is rotatably connected to the thrust bearing 8, and the other end of the screw 7 is connected to the nut main body 5.
[0021] The effect achieved by the entire embodiment 2 is that when the angle-fixed flat-nose pliers clamp the workpiece, the screw 7 and the pliers body 1 bear the tensile force, so the pliers body 1 is slightly deformed, which improves the overall accuracy. The force-bearing surface of the screw 7 is in front of the pliers body 1. Rotating the screw 7 drives the nut body 5 to pull the movable body 3 to add force to the workpiece between the two jaw pads. Through the setting of the thrust bearing 8, the friction is reduced and the clamping force reaches. Since the clamping force is a tensile force, it has the advantages of large clamping force, the workpiece is not easy to float, high repeated positioning accuracy, and the overall deformation is not easy. This device is angle-fixed in design, and the semicircular ball 6 can generate a 30° downward component of force during the tightening process to ensure that the workpiece does not float. The first jaw pad 2 and the second jaw pad 4 are respectively fixed to the pliers body 1 and the movable body 3 by locking bolts, which reduces the dynamic deformation. The device as a whole is quenched to maintain long-term wear resistance and accuracy.
[0022] Working principle: When the device is used, the screw 7 is rotated to make the nut auxiliary group guide rail 9 move under the limit of the limit cavity opened in the pliers body 1, thereby driving the nut main body 5 to pull the movable body 3 to move in the direction of the first jaw pad 2, and clamp the workpiece between the second jaw pad 4 and the first jaw pad 2. The screw 7 is relatively long. When the angle-fixed flat-nose pliers clamp the workpiece, the front end of the screw 7 is rotatably connected to the pliers body 1 through the thrust bearing 8. When the screw 7 rotates and drives the movable body 3 to move and clamp, the thrust and pressure generated by the movable body 3 on the screw 7 due to the action of the thrust bearing 8 , the lead screw 7 and the pliers body 1 will be transformed into bearing tension, and the pressure or thrust on the connection at the rear end of the lead screw 7 is transformed into the tension generated by the front end of the lead screw 7 and the thrust bearing 8. Therefore, the pliers body 1 is slightly deformed, and the overall accuracy is improved. This device is angle-fixed in design. The semicircular ball 6 can generate a 30° downward component of force during the tightening process to ensure that the workpiece does not float. The first jaw pad 2 and the second jaw pad 4 are respectively fixed to the pliers body 1 and the movable body 3 by locking bolts, reducing the dynamic deformation. The entire device is quenched to maintain long-term wear resistance and accuracy. The lead screw 7 and the pliers body 1 bear tension, so the pliers body 1 is slightly deformed, and the overall accuracy is improved.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
