Description

Technical Field

[0001] This utility model relates to the field of machine tool fixture technology, specifically a dual-station adjustable stroke automatic clamping vise. Background Technology

[0002] In the field of machining, bench vises are the most commonly used workpiece clamping devices. Currently, bench vises on the market are mainly divided into two types: single-station and double-station.

[0003] Single-station bench vises are currently the most widely used products. They are simple in structure and easy to operate, but they can only clamp one workpiece at a time, resulting in low processing efficiency. Especially in batch processing, frequent workpiece changes are required, which seriously affects production efficiency. In addition, traditional single-station bench vises mostly use manual clamping, resulting in unstable clamping force, which is difficult to meet the requirements of high-precision machining.

[0004] To address the inefficiency of single-station bench vises, dual-station bench vises have emerged on the market. While these products can clamp two workpieces simultaneously, they generally employ a fixed reference design. When the two workpieces are of different dimensions, one side may be clamped while the other is not fully clamped, severely impacting machining accuracy. Utility Model Content

[0005] The purpose of this invention is to provide a dual-station adjustable stroke automatic clamping vise to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The bench vise base has adjustment seats on both sides of its top, and an adjustment mechanism is provided between the adjustment seats and the bench vise base.

[0009] A fixed base is fixedly connected to the top middle part of the bench vise base, and a hydraulic clamping mechanism is provided between the fixed base and the adjusting base.

[0010] Preferably, the adjustment mechanism includes a movable groove formed inside the lower part of the adjustment seat, and a spring fixedly connected inside the lower part of the movable groove. The upper end of the spring is elastically abutted against a steel ball. The top end of the adjustment seat is threadedly connected to an adjustment screw, and the end of the adjustment screw extends into the movable groove and abuts against the steel ball.

[0011] Preferably, the adjustment mechanism further includes a guide groove opened along the length direction of the bench vise base, the bottom ends of the adjustment seat extend to the inner walls of the guide groove on both sides and slide in cooperation with them, and a plurality of tapered countersunk holes are opened at equal intervals in the middle of the guide groove.

[0012] Preferably, the bench vise base has pressure grooves on both sides of its outer surface, and pressure blocks are movably arranged inside the pressure grooves, with standard bolt holes on the pressure blocks;

[0013] Preferably, the hydraulic clamping mechanism includes a hydraulic cylinder fixedly connected to the top of the adjusting seat, and a first insert plate symmetrically fixedly connected to the outside of both sides of the fixed seat. The output shaft end of the hydraulic cylinder is fixedly connected to a movable seat, and the side of the movable seat facing the first insert plate is fixedly connected to a second insert plate.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-3 As shown, this utility model provides a technical solution:

[0024] A dual-station adjustable-stroke automatic clamping bench vise includes a vise base 1 with adjusting seats 2 on both sides of its top. An adjusting mechanism is provided between the adjusting seats 2 and the vise base 1. The adjusting mechanism includes a movable groove 4 formed inside the lower part of the adjusting seat 2, and a spring 5 fixedly connected inside the lower part of the movable groove 4. A steel ball 6 is elastically abutted at the upper end of the spring 5. An adjusting screw 7 is threaded to the top of the adjusting seat 2, and the end of the adjusting screw 7 extends into the movable groove 4 and abuts against the steel ball 6. The adjusting mechanism also includes a guide groove 8 formed along the length of the vise base 1. The bottom sides of the adjusting seat 2 extend to the inner walls of the guide groove 8 and slide therewith. Several... A tapered countersunk hole 9 is provided. A pressure groove 10 is provided on both sides of the bench vise base 1. A pressure block 11 is movably arranged inside the pressure groove 10. A standard bolt hole is provided on the pressure block 11. A fixed seat 3 is fixedly connected to the top of the middle part of the bench vise base 1. A hydraulic clamping mechanism is provided between the fixed seat 3 and the adjusting seat 2. The hydraulic clamping mechanism includes a hydraulic cylinder 12 fixedly connected to the top of the adjusting seat 2, and a first plate 13 symmetrically fixedly connected to the outside of both sides of the fixed seat 3. A movable seat 14 is fixedly connected to the output shaft end of the hydraulic cylinder 12. A second plate 15 is fixedly connected to the side of the movable seat 14 facing the first plate 13. The lower end surfaces of both sides of the movable seat 14 slide in contact with the upper end surfaces of both sides of the bench vise base 1.

[0025] In this embodiment, by adjusting the combination of set screw 7 and steel ball 6, independent and precise adjustment of the dual-station stroke is achieved, which solves the problem of unstable clamping of workpieces on one side caused by fixed reference in traditional dual-station bench vises. This allows the clamping positions on both sides to be adaptively adjusted according to workpieces of different sizes, significantly improving clamping reliability and machining accuracy.

[0026] Furthermore, by driving the moving seat 14 and the fixed seat 3 to work together through the hydraulic cylinder 12, synchronous automatic clamping of the two stations is realized, which solves the problem of low processing efficiency of the single-station hydraulic vise. At the same time, the structure is compact and saves workbench space.

[0027] Working principle: The vise base 1 is fixed to the workbench surface by the clamping block 11 in the clamping groove 10 and the standard bolt hole. When the clamping stroke needs to be adjusted, first loosen the adjusting screw 7 so that its end moves upward, releasing the downward pressure on the steel ball 6. At this time, the elastic force of the spring 5 will push the steel ball 6 upward, causing it to disengage from the current conical countersunk hole 9. Then, manually push the adjusting seat 2 to slide along the guide groove 8 to the target position. When positioning, tighten the adjusting screw 7 so that its end presses down on the steel ball 6. The steel ball 6 moves downward against the elastic force of the spring 5 until the lower end of the steel ball 6 is inserted into the target conical countersunk hole. Position locking is achieved in hole 9; when clamping the workpiece, hydraulic cylinder 12 drives moving seat 14 to slide along the upper end face of bench vise base 1, driving insert plate 2 15 to move closer to insert plate 1 13 on both sides of fixed seat 3, and clamping the workpiece through the cooperation of insert plate 1 13 and insert plate 2 15; when releasing, hydraulic cylinder 12 moves in the opposite direction to make insert plate 2 15 move away from insert plate 1 13, completing the release of the workpiece. The whole process is automatically clamped and released through hydraulic clamping mechanism. The dual-station design can adjust the clamping stroke on both sides synchronously or independently to adapt to the processing requirements of workpieces of different sizes.
