Abstract
Description
Technical Field
[0001] This utility model belongs to the field of machining technology, specifically relating to a vise clamping device. Background Technology
[0002] Vise clamping is a common operation in machining. It is used to fix workpieces in place for cutting, milling, drilling and other machining processes to achieve efficient and precise operation.
[0003] For mass-produced parts, each time a part is clamped, it needs to be readjusted and positioned, which not only increases processing time but also raises production costs. This leads to a significant cumulative error in workpiece positioning, which in turn affects the machining accuracy of the workpiece.
[0004] There is a workpiece with a hexagonal head that needs to be mass-produced. When machining the hexagonal workpiece by CNC, each clamping of a part requires readjustment and positioning. In order to meet the machining requirements, a new multi-piece clamping and positioning fixture needs to be designed. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] The technical problem this invention aims to solve is: how to reduce the number of clamping operations during mass production of parts and improve production efficiency.
[0007] (II) Technical Solution
[0008] To solve the above-mentioned technical problems, this utility model provides a vise clamping device, including a screw 1, a limiting block 2, a support plate 3, a V-block 4, and a base 6;
[0009] The V-block 4 is a cuboid structure with several V-grooves on its left and right sides, which are used to place the workpiece to be processed. The support plate 3 is fixed to the bottom of the V-block 4. The base 6 is an L-shaped structure with a guide rail groove in its horizontal part. The limiting block 2 and the support plate 3 are slidably engaged with the guide rail groove of the base 6. The V-block 4 is positioned between the limiting block 2 and the base 6. The screw 1 is inserted into the limiting block 2 to push the limiting block 2 to slide, thereby clamping the V-block 4 between the limiting block 2 and the base 6.
[0010] Furthermore, the support plate 3 and the V-block 4 are fixedly connected by bolts.
[0011] Furthermore, the base 6 is fixed on the processing platform.
[0012] Furthermore, the workpiece to be processed is clamped between the V-block 4 and the limiting block 2, and between the V-block 4 and the base 6.
[0013] (III) Beneficial Effects
[0014] Compared with existing technologies, this utility model has the following beneficial effects: it enables mass production, which not only reduces the labor intensity of workers but also greatly shortens auxiliary time, improving production efficiency and reducing production costs while ensuring product quality; secondly, by reducing the number of clamping operations and tool change frequency, it reduces production costs and improves economic efficiency. For some easily deformable parts, multi-piece clamping can reduce the force on a single piece by evenly distributing the cutting force, thereby reducing workpiece deformation; simultaneous processing of multiple parts can ensure the consistency and interchangeability of processing between workpieces, etc. Attached Figure Description

[0023] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0024] The vise clamping device of this embodiment includes a screw 1, a limiting block 2, a support plate 3, a V-block 4, a countersunk bolt 5, and a base 6.
[0025] The V-block 4 is a rectangular plate structure with V-grooves on its left and right sides for fixing the workpiece. Four holes are located on the upper surface of the V-block, which fit tightly with the threaded holes in the support plate 3, restricting the workpiece's movement in the XZ directions. The workpiece has a hexagonal head and a cylindrical tail. A single screw with a cylindrical thread structure is included. The screw, limit block, support plate, and V-block work together to tightly position the workpiece in the X direction.
[0026] One limiting block is provided. The limiting block is an I-shaped plate structure with a central hole in the middle. It cooperates with the screw through the central hole to press the workpiece and achieve the positioning of the workpiece in the X direction.
[0027] One support plate, which is an I-shaped plate structure, fits with the base 6 with a clearance and can slide left and right. There are 4 threaded holes on the upper surface of the support plate, which fit with the V-block.
[0028] One base piece, with a guide rail groove on the bottom surface.
[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
