AI Technical Summary
Existing bench vises tend to tilt upwards when clamping workpieces, resulting in poor clamping accuracy and difficulty in producing qualified products. Furthermore, high-precision vises are expensive, making them unaffordable for small and medium-sized enterprises.
An improved precision bench vise was designed. By setting T-slots and slider structures on the vise body and cover, the connection between the slider and the T-slot ensures that the vise cover and vise body are fixed together and do not separate, thereby preventing the workpiece from tilting upwards. It combines the lightness of ordinary vises with the high precision of precision vises.
It achieves stable workpiece clamping, preventing upward tilting, and its clamping accuracy is comparable to that of a precision vise. It reduces costs and is suitable for the machining needs of small and medium-sized enterprises.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0021] Please refer to Figures 1-4 A technical scheme provided by the utility model:
[0022] An improved precision bench vice without upwarping, comprising a bottom plate 1,
[0023] The bottom plate 1 is provided with a vice body 2 on the surface, the vice body 2 is provided with a fixed jaw 3 at one end of the surface, the vice body 2 is provided with a movable jaw 5 at the end away from the fixed jaw 3, the movable jaw 5 is connected with a vice cover 6, the vice body 2 is provided with a first T-shaped groove 8, the vice cover 6 is provided with a second T-shaped groove 9 at the end close to the vice body 2, and the vice cover 6 is further connected with a sliding block 7.
[0024] Preferably, the fixed jaw 3 and the movable jaw 5 are placed with a workpiece 4 to be processed.
[0025] Preferably, the movable jaw 5 is further connected with a lead screw 10.
[0026] More preferably, the lead screw 10 is connected with a connecting handle.
[0027] The screw rod 10 is connected with the connecting handle, and the screw rod 10 is driven to rotate by clockwise rotation, the screw rod 10 drives the clamp cover 6 and the movable jaw 5 to move forward, cooperates with the fixed jaw 3, and thus clamps the workpiece 4 to be processed.
[0028] Through force analysis on the workpiece 4 to be processed, it is easy to know that if the workpiece 4 to be processed is clamped little and bears large force, the movable jaw will be upwarping due to no resistance in the upward direction, and thus the workpiece is clamped askew and the surface is uneven.
