[0002] In the field of machining, vises are commonly used workpiece clamping devices, and their performance directly affects machining accuracy and efficiency. Traditional vises mainly consist of a base, a fixed clamp body, a movable clamp body, and a drive screw. By rotating the drive screw, the movable clamp body moves, thus clamping the workpiece.

[0003] Traditional vises typically feature rigid translation of their moving jaws. If the workpiece blank has dimensional tolerances or shape errors, it can easily lead to uneven distribution of clamping force, causing workpiece deformation or insecure clamping. Furthermore, for non-rectangular or irregularly shaped workpieces, traditional vises have a small clamping contact area and poor stability. In addition, traditional vises have limited positioning accuracy and repeat clamping accuracy, making it difficult to meet the needs of high-precision machining. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing vise clamps that easily cause workpiece deformation or insecure clamping, poor stability and low clamping accuracy, and to propose an adjustable precision vise clamp.

[0005] To achieve the above objectives, the present invention employs the following technology: an adjustable precision vise clamp, comprising a vise body, a fixed jaw at one end of the top of the vise body, and a movable jaw at the other end of the top of the vise body.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-5 This embodiment provides an adjustable precision vise clamp, including a vise body 1, a fixed jaw 2 fixed at one end of the top of the vise body 1, and a movable jaw 3 set at the other end of the top of the vise body 1. Jaw plates 4 are provided on the sides of the fixed jaw 2 and the movable jaw 3 that are close to each other. Anti-slip teeth are provided on one side of the jaw plates 4. The floating connection component 7 is made of high-quality alloy steel, such as chromium-molybdenum steel, and is quenched and tempered to ensure its overall rigidity and strength and to prevent deformation during clamping. Mounting holes 8 are provided at the four corners of the bottom of the vise body 1. The mounting holes 8 are waist-shaped holes to adapt to the installation requirements of different sizes of workbenches. A clamping drive component 5 for driving the movable jaw 3 to move horizontally is provided on one side of the vise body 1. A floating connection component 7 is provided between the clamping drive component 5 and the movable jaw 3. A positioning component 6 is provided at the top of the vise body 1 near the fixed jaw 2. The clamping drive assembly 5 includes a first screw 51 threaded to one side of the clamp body 1 and a first slide groove 54 opened on the top of the clamp body 1. A first slider 55 is slidably connected in the first slide groove 54. A first knob 52 is fixedly connected to one end of the first screw 51. A movable plate 53 fixed to the top of the first slider 55 is rotatably connected to the other end of the first screw 51 through a bearing. The floating connection assembly 7 includes a first fixing rod 73 fixed to one side of the movable plate 53 and a second fixing rod 74 fixed to one side of the movable jaw 3. One end of the first fixing rod 73 is fixedly connected to a ball socket 71, and a locking screw 75 is threaded onto the ball socket 71. One end of the second fixing rod 74 is fixedly connected to a ball head 72 that is movably nested in the ball socket 71. The ball socket 71 and the ball head 72 are locked together by the locking screw 75.

[0017] Specifically, in use, the clamp is fixed to the processing table with bolts through the mounting hole 8 at the bottom of the clamp body 1, ensuring that the clamp body 1 is horizontal. Then, the workpiece is placed in the vise, with its reference edge close to the positioning baffle 65 and the jaw plate 4 of the fixed jaw 2, which can position the workpiece. Then, the first knob 52 is turned, which drives the first screw 51 to rotate. The first screw 51 drives the moving plate 53 to move towards the fixed jaw 2. The first slider 55 slides along the first slide groove 54, making the horizontal movement of the moving plate 53 more stable, thereby driving the movable jaw 3 to move forward and contact the workpiece. The floating connection assembly 7 starts to work. The ball head 72 can be rotated and finely adjusted along the inner wall of the ball socket 71, which makes it easy to adjust the tilt angle of the movable jaw 3. Through the automatic swing of the movable jaw 3, the working surface of the jaw plate 4 of the movable jaw 3 is completely in contact with the surface of the workpiece. Then, by rotating the locking screw 75, the bottom of the locking screw 75 abuts against the ball head 72, thereby locking the entire floating connection assembly 7 at the optimal angle, which facilitates subsequent processing operations. After the first piece is processed, the efficient batch cycle begins. The operator places the new workpiece into the vise and positions it against the positioning surface formed by the positioning baffle 65 and the jaw plate 4. This allows for rapid workpiece placement and positioning, improving the quality and efficiency of workpiece positioning. Rotating the first screw 51 moves the movable jaw 3 forward. If the workpieces are of uniform shape, the locked movable jaw 3 will contact and clamp the workpieces in the same posture. If the workpieces are of different shapes and sizes, after placing the workpieces on the top of the vise body 1 near the fixed jaw 2, the second screw 62 is rotated to adjust the position. Positioning the positioning baffle 65 so that one side of the positioning baffle 65 is in close contact with the workpiece, and after positioning the workpiece, rotate the first screw 51 to drive the movable jaw 3 forward, loosen the locking screw 75, release the lock on the ball head 72, and the movable jaw 3 will be finely adjusted again to adapt, so that the working surface of the jaw plate 4 of the movable jaw 3 is in contact with the surface of the workpiece, and the workpiece can be clamped, which is convenient for subsequent processing, easy to operate, and can automatically adapt to the dimensional deviation and shape error of the workpiece, so that the clamping force is evenly distributed, greatly reducing the processing error caused by workpiece deformation or insecure clamping.

[0018] Furthermore, the positioning component 6 includes a second slide groove 61 opened on the top of the clamp body 1, and a second screw 62 rotatably installed in the second slide groove 61. One end of the second screw 62 is fixedly connected to a second knob 63, and the other end of the second screw 62 located in the second slide groove 61 is threadedly connected to a second slider 64. The top of the second slider 64 is fixedly connected to a positioning baffle 65. The working surface of the positioning baffle 65 is perpendicular to the working surface of the fixed clamp jaw 2, and the working surface of the positioning baffle 65 is provided with an anti-slip pad.

[0019] Specifically, by rotating the second knob 63, the second screw 62 rotates, and the second slider 64 moves horizontally along the second slide groove 61, thereby moving the positioning baffle 65. After adjusting the position of the positioning baffle 65, the workpiece is placed close to the side of the positioning baffle 65 and the jaw plate 4 to complete the positioning. Therefore, in batch processing, each workpiece is placed in the exact same absolute position, eliminating human positioning errors and ensuring the high uniformity of part dimensions. When processing different workpieces, simply rotate the second knob 63 to adjust the position of the positioning baffle 65 to move it to the new position, thereby providing a highly repeatable and rapid positioning reference, which facilitates the improvement of processing accuracy and efficiency.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
