The lead screw is divided into four parts in the circumferential direction, external threads are arranged on two opposite sides, smooth surfaces are arranged on the two opposite sides, and the arrangement of the internal threads in the screw hole of the nut is matched with the external threads of the lead screw. Compared with the prior art, the invention has the beneficial effects that: the invention provides a rapid clamping bench vice, which can rapidly change the distance between a movable jaw and a fixed jaw through linear pushing when a workpiece is replaced, so that the movable jaw and the fixed jaw are rapidly close to each other, and then the clamping is realized through a thread part.
Description
Technical Field
The invention relates to the technical field of machining, in particular to a quick clamping bench vice.
Background
The clamping bench vice comprises a movable jaw, a fixed jaw, a turntable seat, a clamping disc, a lead screw, a nut and other components (see figure 1). The screw rod is connected with the movable jaw, the nut is installed in the fixed jaw, the screw rod and the nut are screwed and fed to drive the movable jaw to slide back and forth along the slideway, and the movable jaw and the fixed jaw are opened and closed to clamp. The screw rod and the nut of the clamping bench vice in the prior art are all in full thread screw connection, when the movable jaw is clamped and fed, the movable jaw needs to be screwed a bit, if the size change of a machined workpiece is large, the changed stroke is large, and time and labor are wasted when the clamping distance is changed.
Disclosure of Invention
The invention aims to provide a rapid clamping bench vice, which can rapidly change the distance between a movable jaw and a fixed jaw by linear pushing when a workpiece is replaced, so that the movable jaw and the fixed jaw can be rapidly close to each other, and then the clamping is realized through a thread part.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a rapid clamping bench vice, includes movable vice jaw, fixed vice jaw, lead screw, nut, the lead screw is connected with movable vice jaw, the nut is installed in fixed vice jaw, lead screw and nut spiro union, the lead screw passes through half threaded connection with the nut.
The lead screw is divided into four parts in the circumferential direction, external threads are arranged on two opposite sides, smooth surfaces are arranged on the two opposite sides, and the arrangement of the internal threads in the screw hole of the nut corresponds to the smooth surfaces of the external threads of the lead screw.
Compared with the prior art, the invention has the beneficial effects that:
the invention provides a rapid clamping bench vice, which can rapidly change the distance between a movable jaw and a fixed jaw through linear pushing when a workpiece is replaced, so that the movable jaw and the fixed jaw are rapidly close to each other, and then the clamping is realized through a thread part.
Drawings
FIG. 1 is a schematic view of a clamping vise;
FIG. 2 is a schematic view of the head of the clamping vise;
FIG. 3 is a schematic view of the nut of the present invention;
FIG. 4 is a schematic view of the structure of the lead screw of the present invention.
In the figure: 1-movable jaw, 2-fixed jaw, 3-nut, 4-screw smooth surface, 5-clamping disc, 6-turntable seat, 7-screw, 8-handle, 9-screw head, 10-internal thread, 11-screw hole, 12-nut smooth surface and 13-external thread.
Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings:
referring to fig. 1-4, the rapid clamping bench vice comprises a movable jaw 1, a fixed jaw 2, a lead screw 7 and a nut 3, wherein the lead screw 7 is connected with the movable jaw 1, the nut 3 is installed in the fixed jaw 2, the lead screw 7 is in threaded connection with the nut 3, and the lead screw 7 is in half-threaded connection with the nut 3.
The lead screw 7 is divided into four parts in the circumferential direction, external threads 13 are arranged on two opposite sides, smooth surfaces are arranged on the other two opposite sides, and the arrangement of the internal threads 10 in the nut screw hole 11 corresponds to the smooth surfaces of the external threads 13 of the lead screw.
When the clamping distance between the movable jaw 1 and the fixed jaw 2 is changed, the external thread 13 of the screw rod 7 is rotated to be opposite to the nut smooth surface 12 through the handle, the movable jaw 1 is pushed, the movable jaw 1 is directly leaned against a workpiece, the screw rod 7 is screwed by the handle 8, the clamping action of the workpiece can be completed, and the workpiece can be loosened through reverse rotation.
As shown in fig. 3 and 4, two sections of external threads 13 on the screw 7 are longer than the other section of external threads. The position of the internal thread 10 of the nut corresponds to the smooth part of the external thread 13 of the screw rod, and 360-degree screwing and locking can be realized during locking.
The invention greatly reduces the workpiece clamping time, reduces the production cost and improves the working efficiency; the safety and the reliability are realized; generally for hand vise; generally for moderate clamping forces.
