As shown in fig. 1 to 3, the wedge-type clamp according to the embodiment of the first aspect of the present invention includes a base 100, a first clamping portion 200 and a second clamping portion 300, wherein the upper surface of the base 100 is provided with a sliding slot 110 disposed in front and at the back, the second clamping portion 300 includes a movable block 310, a wedge block 320, a locking mechanism 330 and a clamping bolt 340, and a sliding block 311 matched with the sliding slot 110 is disposed at the bottom of the movable block 310, so that the movable block 310 can be slidably connected to the sliding slot 110. Specifically, the sliding groove 110 is a T-shaped groove, the width of the upper groove of the T-shaped groove is smaller than that of the lower groove thereof, the locking mechanism 330 includes a locking bolt 331 and a locking block 332, the locking block 332 is disposed in the T-shaped groove in a limiting manner, that is, the locking block 332 is located in the lower groove of the T-shaped groove, and the width of the locking block 332 is greater than that of the upper groove thereof; the movable block 310 is provided with a second counter bore 312 corresponding to the sliding groove 110, the locking block 332 is provided with a second threaded hole 3321, and the locking bolt 331 sequentially penetrates through the second counter bore 312 and the upper groove downwards and is in threaded connection with the second threaded hole 3321. When the user gradually tightens the locking bolt 331, since the vertical position of the locking block 332 is not changeable, the locking bolt 331 can gradually press the movable block 310 against the slide groove 110, so that the movable block 310 can be locked to the slide groove 110 by the locking mechanism 330 to temporarily fix the position of the movable block 310. Meanwhile, the connection manner of the first clamping portion 200 and the base 100 is consistent with the connection manner of the second clamping portion 300 and the base 100, so that the first clamping portion 200 can be temporarily fixed on the base 100, but the present invention does not limit the connection manner of the first clamping portion 200 and the base 100, and the first clamping portion 200 can also be fixedly connected on the base 100, but is not limited thereto. In addition, regardless of the manner in which the first clamping portion 200 is connected to the base 100, when a workpiece needs to be clamped, the position of the first clamping portion 200 must be fixed to the base 100.
In some embodiments of the present invention, in order to improve the locking effect of the movable block 310, the number of the locking mechanisms 330 may be two.
As shown in fig. 3 and 4, the rear side surface of the first clamping portion 200 is a first clamping surface 210, the movable block 310 is provided with a first inclined surface 302 facing the first clamping surface 210, and the first inclined surface 302 is inclined backward from bottom to top; the wedge block 320 is located between the first clamping surface 210 and the first inclined surface 302, the front side surface of the wedge block 320 is a second clamping surface 321, the rear side surface of the wedge block 320 is a second inclined surface 322 matched with the first inclined surface 302, the second clamping surface 321 is opposite to the first clamping surface 210, the wedge block 320 is provided with a first countersunk hole 323 which is vertically communicated, the movable block 310 is provided with a horizontal plane 301 below the wedge block 320, the horizontal plane 301 is connected with the first inclined surface 302, the horizontal plane 301 is provided with a first threaded hole 313 corresponding to the first countersunk hole 323, and the clamping bolt 340 downwards penetrates through the first countersunk hole 323 and is in threaded connection with the first threaded hole 313. When a workpiece is clamped for the first time, the workpiece to be machined is firstly placed between the two clamping surfaces, then the position of the second clamping surface 321 is rapidly adjusted by sliding the movable seat until the workpiece to be machined is abutted to the first clamping surface 210 and the second clamping surface 321, and then the position of the movable seat is locked by the locking mechanism 330; since the wedge press block 320 can be gradually moved downward as the clamping screw 340 is gradually tightened, during which the second clamping surface 321 gradually approaches the first clamping surface 210 under the action of the wedge, the position of the second clamping surface 321 can be finely adjusted by tightening the clamping screw 340 until both clamping surfaces clamp the workpiece to be machined. When the utility model needs to change the positioning direction of the workpiece, the movable block 310 needs to be unlocked first, i.e. the locking bolt 331 is loosened, and at this time, the user can adjust the position of the movable block 310 at will; and putting the workpiece with the adjusted positioning direction into the wedge-pressing type clamp again, then quickly adjusting the position of the second clamping surface 321 by sliding the movable seat until the workpiece to be machined is abutted to the first clamping surface 210 and the second clamping surface 321, locking the position of the movable seat by the locking mechanism 330, and finally clamping the workpiece according to the clamping steps.
It should be further noted that, since the front and rear positions of the clamping bolt 340 are not changed in the process of clamping the workpiece, but the first counter sink 323 moves back and forth along with the wedge block 320, in order to avoid interference between the two, the clamping bolt 340 is in clearance fit with the first counter sink 323, and a certain margin is left between the two.
In some embodiments of the present invention, for the convenience of the user, the locking bolt 331 and the clamping bolt 340 may be selected as a butterfly bolt, so that the user can manually tighten or loosen the bolt. However, the utility model discloses do not prescribe a limit to the type of bolt, locking bolt 331 with clamping bolt 340 still can be hexagon socket head cap screw or cross bolt, if nevertheless locking bolt 331 with clamping bolt 340 is hexagon socket head cap screw or cross bolt, the user then need rely on the instrument to screw or unscrew the bolt.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
