[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] refer to Figure 1-5A positioning vise includes a fixed base 1, a mounting block 2 provided at one end of the fixed base 1, a fixed block 3 provided at the other end of the fixed base 1, and a movable block 4 provided between the mounting block 2 and the fixed block 3. The movable block 4 and the fixed block 3 form a clamping space to clamp and fix a workpiece on the fixed base 1. Clamping plates are provided on the top of the movable block 4 and the top of the fixed block 3. The workpiece can be clamped and released by moving the two clamping plates closer and farther from each other. This is a prior art and will not be described in detail here.

[0040] An adjusting device 6 is provided between the fixed block 3 and the mounting block 2 . The adjusting device 6 is connected to the movable block 4 . The movable block 4 is moved on the fixed seat 1 through the adjusting device 6 , thereby adjusting the size of the clamping space.

[0041] A positioning component 5 is also provided between the mounting block 2 and the fixed block 3. The positioning component 5 is provided on one side of the clamping space. When clamping the workpiece, it can limit the movement of one side of the workpiece, thereby realizing the positioning of the workpiece on one side of the fixed seat 1, and then realizing fast and accurate positioning of the workpiece when clamping, thereby improving processing efficiency.

[0042] In some embodiments, the positioning assembly 5 includes a slider 51, which is slidably arranged on the fixed seat 1; a positioning block 52 is provided on the slider 51, and the positioning assembly 5 also includes a lifting member, which can realize the lifting and lowering of the positioning block 52, thereby realizing the change of the height of the positioning block 52 in the clamping space, and then realizing the positioning of the workpiece when the positioning block 52 protrudes, and avoiding the influence on the workpiece processing when the positioning block 52 is hidden.

[0043] Specifically, the lifting member includes a lifting groove 53, which is provided on the side of the slider 51 close to the clamping space, and the positioning block 52 is inserted into the lifting groove 53; the cross-section of the lifting groove 53 can be T-shaped, which can prevent the positioning block 52 from sliding out of the lifting groove 53; a reset spring 54 is provided between the bottom wall of the lifting groove 53 and the bottom of the positioning block 52, which can provide a force for the positioning block 52 to reset, so that the positioning block 52 protrudes, thereby providing the side positioning of the workpiece when clamping the workpiece, thereby realizing fast and accurate positioning of the workpiece when clamping, and improving processing efficiency.

[0044] The positioning block 52 is provided with a limit groove 55 on the side close to the clamping space, and a slidable limit block 56 is provided in the limit groove 55; a limit spring 57 is provided between the side wall of the limit groove 55 and the limit block 56, and the limit spring 57 can provide the force for the limit block 56 to reset; the slider 51 is provided with a docking groove 58 on the side close to the clamping space, and the docking groove 58 can be plugged into and matched with the limit block 56. When the limit groove 55 and the docking groove 58 are located in the same horizontal plane, the limit block 56 slides toward the docking groove 58 under the action of the limit spring 57 and is plugged into and matched with the docking groove 58, thereby realizing the fixation of the positioning block 52 in the lifting groove 53, and then realizing the hiding of the positioning block 52, avoiding the protrusion of the positioning block 52 and the influence on the workpiece processing.

[0045] In some embodiments, the adjusting device 6 includes an adjusting screw 61, one end of which is rotatably connected to the fixed block 3, and the other end passes through the mounting block 2 and is threadedly engaged with the movable block 4. Two fixed rods 62 can be symmetrically provided between the mounting block 2 and the fixed block 3, and the fixed rods 62 pass through the movable block 4; the adjusting screw 61 is fixedly connected to a rotating wheel 63 at one end away from the fixed block 3, and the rotation of the rotating wheel 63 drives the adjusting screw 61 to rotate. Due to the limiting effect of the two fixed rods 62, the rotation of the adjusting screw 61 is converted into the movement of the movable block 4, thereby adjusting the position of the movable block 4, realizing the change of the distance between the fixed block 3 and the movable block 4, and then realizing the adjustment of the size of the clamping space.

[0046] In some embodiments, the outer surface of the rotating wheel 63 is provided with a scale to visualize the change in the size of the clamping space and facilitate adjustment.

[0047] In some embodiments, a transmission assembly 7 is further included. The transmission assembly 7 includes a sliding groove 71 and a transmission screw 72. The sliding groove 71 is provided on the side of the fixed base 1 near the slider 51. The sliding groove 71 contains the slidable slider 51. One end of the transmission screw 72 is rotatably connected to the fixed block 3, and the other end is rotatably connected to the mounting block 2. The transmission screw 72 passes through the slider 51 and is threadedly engaged with the slider 51. By rotating the transmission screw 72, the slider 51 is driven to slide within the sliding groove 71. This facilitates adjustment of the position of the positioning block 52, so that the force applied to the workpiece during clamping is more uniform, thereby improving the positioning accuracy of the workpiece.

[0048] A transmission cavity is provided in the mounting block 2, and a transmission member is provided in the transmission cavity. The transmission member includes a driving gear 73 and a driven gear 74. The driving gear 73 is sleeved on the adjusting screw 61, and the driven gear 74 is sleeved on the transmission screw 72 and meshes with the driving gear 73; through the meshing between the driving gear 73 and the driven gear 74, the adjusting screw 61 and the transmission screw 72 can be rotated simultaneously, thereby realizing the simultaneous movement of the slider 51 and the movable block 4, thereby improving the convenience of the workpiece clamping process.

[0049] In some embodiments, the symmetry axis of the positioning block 52 is coaxial with the symmetry axis of the clamping space, and the transmission ratio of the driving gear 73 and the driven gear 74 can be 0.5, so that the positioning block 52 is always coaxial with the clamping space during the adjustment process, thereby improving the uniformity of the force during the workpiece clamping process, thereby further improving the clamping accuracy of the workpiece.

[0050] The specific working principle is as follows:

[0051] During specific adjustment, the rotating wheel 63 is rotated to drive the adjusting screw 61 to rotate. Since the adjusting screw 61 is threadedly engaged with the movable block 4, the movable block 4 will slide along the fixed rod 62 toward the mounting block 2, making the clamping space larger than the workpiece.

[0052] Place the workpiece within the clamping space and rotate the wheel 63 in the opposite direction, driving the adjusting screw 61 in the opposite direction. The movable block 4 will slide along the fixing rod 62 away from the mounting block 2, thereby securing the workpiece within the clamping space. As the movable block 4 slides away from the mounting block 2, the meshing transmission of the driven gear 74 and the driving gear 73 causes the adjusting screw 61 to drive the driving screw 72, causing the positioning block 52 to follow the movable block 4. During the clamping process, the workpiece's sides are always restrained by the positioning block 52, preventing lateral movement of the workpiece and achieving rapid and precise positioning of the workpiece.

[0053] After the workpiece is clamped and fixed, the positioning block 52 is pressed, the return spring 54 is deformed by the force, and the positioning block 52 moves toward the bottom wall of the lifting groove 53. When the limit groove 55 and the docking groove 58 are located in the same horizontal plane, the limit block 56 slides toward the docking groove 58 under the action of the limit spring 57 and engages with the docking groove 58, thereby fixing the positioning block 52 in the lifting groove 53, and then hiding the positioning block 52, avoiding the protrusion of the positioning block 52 and affecting the workpiece processing.

[0054] After the workpiece is processed, the wheel 63 is rotated to open the clamping space, the processed workpiece is taken out, and the limit block 56 is pressed. The limit block 56 squeezes the limit spring 57 to deform, and the limit block 56 moves in the limit groove 55 away from the docking groove 58. The limit groove 55 loses the constraint on the limit block 56. The positioning block 52 slides in the lifting groove 53 away from the bottom wall of the lifting groove 53 under the action of the reset spring 54, and the protruding slider 51 can provide the function of side positioning of the workpiece when clamping the workpiece.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
