Description
Technical Field
The utility model relates to a floating type clamping mechanism, and belongs to the technical field of mechanical tool fixtures.
Background
In the machine manufacturing process, a clamping mechanism is used for fixing a processing object to enable the processing object to occupy the correct position to receive construction or detection. At present, clamping jaws on the market are generally directly screwed on a sliding block through bolts, and the sliding block drives the clamping jaws to clamp or loosen a processing object when moving; the phenomenon of locking can appear when removing, has reduced the tight efficiency of clamp, has increased cost of maintenance.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to provide a floating type clamping mechanism aiming at the prior art, which has simple structure and convenient operation, avoids the phenomenon of locking during moving and improves the processing efficiency.
The technical scheme adopted by the utility model for solving the problems is as follows: the utility model provides a floating clamping mechanism, includes mounting plate, the last lead screw that the level was arranged that is equipped with of mounting plate, be equipped with the screw that two intervals were arranged on the lead screw, be equipped with the movable plate on the screw respectively, pass through positioning bolt fixed connection between movable plate and the screw, set up the clamping jaw unit on the movable plate respectively, the drive when the lead screw rotates for two screws, two movable plates are close to each other and make two clamping jaw units be close to and press from both sides tight work piece or two screws, two movable plates keep away from each other and make two clamping jaw units keep away from and loosen the work piece.
The guide rail is symmetrically provided with two sides of the screw rod, the guide rail is respectively provided with two sliding blocks which are arranged front and back, the moving plate respectively stretches across the two guide rails, and the moving plate is fixed on the sliding blocks which are arranged left and right.
The clamping jaw unit comprises two clamping jaws, and the clamping jaws are fixed on two sides of the moving plate.
And the screw rod is provided with two thread sections with opposite rotation directions.
Compared with the prior art, the utility model has the advantages that: a movable plate is fixedly connected with a nut through a positioning bolt, the nut and the movable plate are in floating installation, and the phenomenon of blocking during movement is avoided. This application simple structure, the simple operation has improved and has pressed from both sides tight efficiency, has reduced cost of maintenance.
Drawings

Detailed Description
The utility model is described in further detail below with reference to the accompanying examples.
As shown in fig. 1, 2, and 3, the floating clamping mechanism in this embodiment includes an installation base plate 2, a screw rod 9 horizontally disposed on the installation base plate 2, two screw thread sections with opposite rotation directions on the screw rod 9, two bearings 8 with seats disposed on the installation base plate 2, and two ends of the screw rod 9 penetrate through the bearings 8 with seats disposed on corresponding sides, so that the screw rod 9 can rotate in the bearings 8 with seats. The screw rod 9 is provided with two nuts 3 which are arranged at intervals, and the nuts 3 are in threaded connection with the corresponding threaded sections. The screw 3 is respectively provided with a movable plate 5, the movable plate 5 is fixedly connected with the screw 3 through a positioning bolt 10, the movable plate 5 is provided with a clamping jaw unit, the mounting bottom plate 2 is provided with a motor base, a motor 1 is arranged in the motor base, an output shaft of the motor 1 is connected with a screw rod 9, and when the motor 1 drives the screw rod 9 to rotate, the two screws 3 and the two movable plates 5 are driven to mutually approach to enable the clamping jaw unit to clamp a workpiece or the two screws 3 and the two movable plates 5 are mutually far away to enable the clamping jaw unit to loosen the workpiece.
Still set up the direction unit on mounting plate 2, the direction unit includes two linear guide 7 that lead to long, and two linear guide 7 symmetric arrangement are equipped with two sliders 4 of arranging around respectively on the linear guide 7 on the lead screw both sides and being fixed in mounting plate 2, and left and right side slider 4 symmetric arrangement. The moving plates 5 respectively span the two guide rails 7, and the moving plates 5 are fixed on the sliders 4 which are symmetrically arranged left and right. When the moving plate 5 moves, the sliding block 4 is driven to move along the linear guide rail 7, the moving plate 5 is guided, and the moving plate 5 is prevented from shaking in the moving process.
The clamping jaw unit comprises two clamping jaws 6, and the clamping jaws 6 are fixed on two sides of the moving plate 5.
The movable plate is fixedly connected with the screw through the positioning bolt, the screw and the movable plate are in floating installation, and the phenomenon of blocking during moving is avoided. This application simple structure, the simple operation has improved and has pressed from both sides tight efficiency, has reduced cost of maintenance.
In addition to the above embodiments, the present invention also includes other embodiments, and any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of the claims of the present invention.
