Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a technical solution: the utility model provides a frock clamp convenient to change, includes bottom plate 1 and sets up the bar groove on bottom plate 1, bar inslot rotation is connected with two-way screw rod 2, and threaded connection has two swivel nuts 3 on two-way screw rod 2, is connected with U type frame 4 on the swivel nut 3, and it is provided with movable plate 5 to slide in the U type frame 4, and the side of movable plate 5 is provided with splint 6, is connected with two location on the splint 6 and colludes 7, is provided with on the movable plate 5 to be used for colluding 7 to the location and carries out the locating component who fixes.

As shown in fig. 1, when the workpiece needs to be clamped and fixed, the workpiece is firstly placed between two clamping plates 6, and then the two-way screw 2 is rotated, because the two-way screw 2 is in threaded connection with two thread sleeves 3 and the rotation of the thread sleeves 3 is limited by the strip-shaped grooves, the two thread sleeves 3 can drive the two clamping plates 6 to move close to each other, so that the workpiece can be clamped and fixed.

The positioning hook 7 comprises a positioning block 71 and a notch formed in the positioning block 71, and the positioning assembly is convenient to fix the positioning hook 7 through the notch.

The movable plate 5 is provided with a threaded through hole, the U-shaped frame 4 is rotatably connected with a screw 8 in threaded connection with the threaded through hole through a bearing sleeve, the movable plate 5 is connected with a limiting plate 9, and the inner wall of the U-shaped frame 4 is provided with a limiting groove 10 for the limiting plate 9 to slide.

As fig. 2, when the height of splint 6 needs to be adjusted, screw 8 rotates, because screw 8 and screw thread through-hole threaded connection, and limiting plate 9 and spacing groove 10 have restricted the rotation of moving plate 5 for moving plate 5 can reciprocate along screw 8, thereby drives splint 6 and reciprocates, has changed splint 6's position, conveniently carries out the centre gripping to the work piece of different height dimensions.

Fixedly connected with scale 11 on U type frame 4, scale 11 makes the more accurate in position of adjusting splint 6.

The locating component comprises a cavity arranged inside the moving plate 5, a locating plate 12 is arranged in the cavity in a sliding mode, an inserting opening 16 for the locating hook 7 to penetrate through is formed in the locating plate 12, a locating hole communicated with the cavity is formed in the moving plate 5, the inner diameter of the inserting opening 16 is slightly larger than the outer diameter of the locating hook 7, and a spring 13 used for pushing the locating plate 12 to move upwards is arranged in the cavity.

The top of the moving plate 5 is provided with a threaded hole opposite to the cavity, a threaded column 14 is connected in the threaded hole in a threaded manner, the threaded column 14 is rotated, and the threaded column 14 is rotated to push the positioning plate 12 to be clamped in the notch on the positioning block 71 downwards.

As shown in fig. 3, the positioning plate 12 is pushed to move upwards under the action of the elastic force of the spring 13, so that the insertion hole 16 is aligned with the positioning hole, after a proper splint is selected, the positioning hook 7 passes through the positioning hole and penetrates through the insertion hole 16, then the threaded column 14 rotates downwards by rotating the threaded column 14, the positioning plate 12 is pushed to move downwards, the spring 13 is compressed and accumulates elastic potential energy, so that the positioning plate 12 is clamped into the groove on the positioning block 71, the locking and fixing of the positioning hook 7 are realized, and the installation and the fixing of the splint 6 can be realized.

When splint 6 is dismantled to needs, rotate screw thread post 14 for screw thread post 14 moves upwards soon, can promote locating plate 12 and move up under the effect of spring 13 elasticity potential energy, makes locating plate 12 break away from the notch on locating piece 71, has removed the locking to location collude 7, can take off splint 6 afterwards, is convenient for according to the concrete shape of work piece, selects suitable splint, more firm stable to the work piece centre gripping.

The bottom on the screw thread post 14 is provided with rubber lag 15, and rubber lag 15 has played the guard action to moving plate 5, and rubber lag 15 has played the guard action to locating plate 12, has avoided screw thread post 14 to move down soon, can harm the surface of locating plate 12.
