Abstract
The invention discloses a manual combined clamping device. The device is characterized by comprising a pressing plate, a spherical washer, an adjusting nut, a screw rod, a locking nut, a rotating wheel, a pin, a gasket, a pressure spring, a screw rod locking nut, a tapered wedge, a standard steel wire ring, a support, a force application screw, a fastening screw, a base plate, guide rails, first countersunk head screws and second countersunk head screws. The base plate is connected to a clamp body through the second countersunk head screws, and the two guide rails are connected to the two sides of the upper portion of the base plate through the first countersunk head screws; the support is arranged on the base plate; the force application screw vertically penetrates through the support; and the top of the force application screw is connected with the tapered wedge. According to the clamping device, three-stage reinforcement manual clamping of a spiral-tapered wedge-pressing plate combination is adopted, and larger clamping force can be obtained. When the height size of the clamping face of a workpiece is changed, the workpiece can be clamped only by replacing the base plate, the design requirement of a flexible clamp is met, and therefore the design and manufacturing cost of the clamping device is effectively reduced, and the production preparation period of the clamping device is effectively shortened.
Description
technical field [0001] The invention relates to the technical field of machine tool fixtures, in particular to a manual combined clamping device. Background technique [0002] The adoption of green design and manufacturing is the only way for the manufacturing industry to implement sustainable development strategies and solve environmental pollution problems. Before the parts are processed, the parts need to be fixed. Machine tool fixture is an indispensable process equipment in the manufacturing industry, so it must develop in the direction of greening. At present, the characteristics of incoming parts are usually adopted, and the parts processed on behalf of others are manually clamped to the bench vise or fixture. From the perspective of energy form, the manual clamping device can be said to be the most green fixture. A fatal shortcoming of the traditional manual clamping device is that the clamping force is not strong due to the limitation of the force of the human ha...
