Description

This invention relates to the art of vises, and more particularly to a vise device having a digital display mechanism for clamping force that is immediately perceptible and capable of displaying a numerical value of the vise's clamping force. In conventional vise structures and operating methods, as shown in Figure 1, the workpiece 200 is placed within the jaw opening range on the vise body 101 of the vise 100, and when the operator rotates the handle 102 at the rear end of the vise 100, the screw rod 103 is made to rotate in synchronous conjunction, and the nut seat 104 and movable jaw 105 are driven to move toward the workpiece 200 via the screw rod 103. When the workpiece 200 is gripped by the contact of the clamping surfaces of the movable jaw 105 and the fixed jaw 106, the operator can activate the pressure boosting mechanism 107 connected to the rear end of the screw rod 103 by continuously rotating the handle 102 again. The pressure boosting mechanism 107 may generally be a hydraulic pressure boosting mechanism, a mechanically operated pressure boosting mechanism, a pneumatic pressure boosting mechanism, a screw pressure boosting mechanism, or other types of mechanisms. By continuously pushing the screw rod 103, the movable jaw 105 can be pressurized toward the fixed jaw 106, thereby gripping the workpiece. Please refer to the following literature on conventional vice technology. U.S. Patent No. 2,771,803US Patent No. 9095958 (B2)US Patent No. 6773003 (B2)U.S. Patent No. 6,053,490 This is a side cross-sectional view showing a conventional vise structure and operating method.This is a perspective view showing a preferred embodiment of the vise device of the present invention.This is a side cross-sectional view showing a preferred embodiment of the vice device of the present invention.This is a plan view showing a preferred embodiment of the vise device of the present invention.This is a rear view showing a preferred embodiment of the vise device of the present invention.This is a block diagram showing the units of the digital display device for the vice apparatus of the present invention. Hereinafter, a vise device according to an embodiment of the present invention will be described with reference to the drawings. As shown in Figures 2 to 6, a preferred specific embodiment of the vice device of the present invention comprises a vice 10, a sensor element 20, and a digital display device 30. One preferred embodiment of the vise 10 comprises a vise body 11, a nut seat 12, a screw rod support seat 13, a screw rod 14, and two clamp jaws 15 and 16. The upper end of the vise body 11 has two slide rails 111 extending parallel to each other at both the front and rear ends, and a housing groove 112 extending at both the front and rear ends is formed between the two slide rails 111. The nut seat 12 is installed in the housing groove 112 of the vise body 11, so that the nut seat 12 can be linked to the movement of the clamp jaws 16 back and forth within the housing groove 112. The screw rod support seat 13 is connected to the rear end of the vise body 11 via a screw fastening structure and acts as a fulcrum for supporting and rotating the screw rod 14. The screw rod 14 is inserted through the screw rod support seat 13, so that the front end of the screw rod 14 is screwed into the nut seat 12, and the rear end of the screw rod 14 protrudes from the rear surface of the screw rod support seat 13, and is configured to move in conjunction with the rotation of the screw rod 14 so that the nut seat 12 moves back and forth. One of the two clamp jaws 15 and 16, clamp jaw 15, is fixedly coupled to both slide rails 111 at the front end of the vise body 11 and operates as a fixed jaw, while the other clamp jaw 16 operates as a movable jaw by being screwed onto a nut seat 12. Furthermore, the vise 10 may be configured to include a pressure booster 17. The pressure booster 17 may be a conventional item, such as a hydraulic pressure booster, a mechanically powered pressure booster, a pneumatic pressure booster, a screw pressure booster, or other structure. The pressure booster 17 is coupled to the rear end of the screw rod 14, and a tool hole for the operator to connect the handle 18 to the rear end of the pressure booster 17 is used to rotate the pressure booster 17 and the screw rod 14 synchronously. As the screw rod 14 rotates, one of the clamp jaws 16 is driven to move onto the vise body 11, thereby creating an opening between the two clamp jaws 15 and 16 sufficient to clamp a workpiece. The sensor element 20 is installed on the screw rod support seat 13 of the vise 10. Specifically, it may be one of a pressure sensor, an electromagnetic induction sensor, or a capacitive sensor. It is used to sense the reaction force transmitted from the screw rod 14 to the screw rod support seat 13 when the clamp jaws 16 are driven by the screw rod 14 to clamp a workpiece, thereby causing the sensor element 20 to generate a signal.
