Detailed Description
In order that the invention may be more fully understood, reference will now be made to the accompanying drawings. The invention may be embodied in different forms and is not limited to the embodiments described herein. Rather, the embodiments are provided so that this disclosure will be thorough and complete.
As shown in the attached drawings, the manual combination clamping device comprises a pressure plate 3, a spherical washer 4, an adjusting nut 5, a screw 6, a locking nut 7, a rotating wheel 9, a pin 10, a gasket 11, a pressure spring 12, a screw locking nut 13, a wedge 14, a standard steel wire ring 15, a support 16, a force application screw 17, a fastening screw 18, a backing plate 19, a guide rail 21, a first countersunk screw 22 and a second countersunk screw 23.
The backing plate is connected and arranged on the clamp body 20 through second countersunk head screws 23, two guide rails 21 are arranged, and the two guide rails are connected and arranged on two sides above the backing plate 19 through first countersunk head screws 22 to form guide grooves; the backing plate 19 is provided with a support 16, and the support 16 and the backing plate 19 are fixedly connected through a fastening screw 18; the force application screw 17 vertically penetrates through the support 16 in a threaded connection mode.
The top of the force application screw 17 is connected with the wedge 14 through a standard steel wire ring 15, and the wedge 14 is fixed in a guide groove formed by a guide rail 21. It can be ensured that the wedge 14 can only move left and right along with the rotation of the force application screw 17 and can not rotate.
One end of the screw rod 6 is in threaded connection with the screw rod locking nut 13 and is fixed on the clamp body 20 in a threaded connection mode; the screw rod 6 is sleeved with a pressure spring 12, a gasket 11, a pressing plate 3, a spherical washer 4, an adjusting nut 5 and a locking nut 7 from bottom to top, and the adjusting nut 5 and the locking nut 7 are both in threaded connection with the screw rod 6.
The pressing plate 3 is connected with the rotating wheel 9 through the pin 10 in the end groove close to the wedge 14, so that rolling friction is generated between the pressing plate 3 and the wedge 14, large resistance caused by sliding friction is reduced, and manual operation is more convenient. The inclined plane of the inclined wedge 14 is provided with a groove, and the bottom of the rotating wheel 9 is arranged in the groove of the inclined wedge 14, so that the deflection of the pressing plate 3 in the process of clamping the workpiece 2 can be avoided, and the left end of the pressing plate 3 can only move up and down. The end of the pressure plate 3 far away from the wedge 14 is of a downwardly convex arc surface structure. The left end of the pressing plate 3 adopts a convex arc surface structure and is matched with the spherical washer 4, so that the same batch of workpieces 2 can not be influenced by the height dimension error of the clamping surface when being clamped, and the workpieces 2 can be effectively clamped. And a long hole 8 is formed in the middle of the pressing plate 3. The middle part of the pressure plate 3 is designed by a long hole 8, so that the pressure plate can adapt to the change of the position of a clamping point. The design of the guide rail 21 can ensure that the inclined wedge 14 can only move left and right, and deflection in the moving process is avoided.
In operation, the workpiece 2 is first positioned on the positioning device 1. The force application screw 17 is screwed by a wrench to push the wedge 14 to move leftwards along a guide groove formed by the two guide rails 21, the rotating wheel 9 in the inclined groove of the wedge 14 is driven to rotate around the pin 10, the right end of the pressing plate 3 is forced to move upwards, and meanwhile, the pressing plate 3 rotates anticlockwise by taking the contact part of the pressing plate 3 and the screw 6 as a fulcrum, so that the left end of the pressing plate 3 downwards clamps the workpiece 2. After the workpiece is machined, the force application screw 17 is reversely screwed by a wrench to drive the wedge 14 to move rightwards along the guide groove formed by the two guide rails 21, the rotating wheel 9 moves downwards along the inclined groove of the wedge 14 due to self weight to drive the right end of the pressing plate 3 to move downwards, meanwhile, the pressing plate 3 rotates clockwise by taking the contact part of the pressing plate and the screw rod 6 as a fulcrum, and the workpiece is upwards loosened at the left end of the pressing plate 3 under the cooperation of the pressure spring 12, so that the workpiece can be freely assembled and disassembled.
When the height dimension of the clamping surface of the workpiece 2 changes, the depth dimension of the screw 6 screwed into the clamp body 20 needs to be adjusted to a proper position in advance, and then the screw is locked by the screw locking nut 13; and (3) finely adjusting the adjusting nut 5 to enable the pressing plate 3 to be basically in a horizontal position after clamping the workpiece 2, and then locking by using a locking nut 7. When the height dimension of the clamping surface of the workpiece 2 is greatly changed, the screw rods 6 with different length dimensions and the backing plates 19 with different height dimensions need to be replaced, so that the design and manufacturing cost and the production preparation period of the clamp are effectively reduced.
In the above embodiments, all functions may be implemented, or a part of the functions may be implemented as necessary.
It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. The invention is not described in detail in order to avoid unnecessary repetition.
