Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

With reference to fig. 1 to 4, a bar clamp of the present invention is schematically shown, which includes a base 3, a first nut 1 and a first clamping member 2, wherein the base 3 is plate-shaped.

The base 3 is provided with a positioning plate 31, a guide screw 32 and a second clamping piece 33, and the guide screw 32 is arranged perpendicular to the base 3. The first clamping member 2 is slidably sleeved on the guide screw rod 32, the first nut 1 is movably connected to the guide screw rod 32 in a matching manner, the end surface of the first nut 1 movably abuts against the side wall of the first clamping member 2, and when the first nut 1 is rotated, the first nut 1 moves along the axial direction of the guide screw rod 32 to push the first clamping member 2 to slide on the guide screw rod 32. The end part of the first clamping piece 2 and the end part of the second clamping piece 33 are abutted to the side wall of the bar 4, the end face of the bar 4 is abutted to the positioning plate 31, the first clamping piece 2 and the second clamping piece 33 can limit the degree of freedom of the bar 4 together, and the clamp can stably clamp the bar 4.

Specifically, the first clamping member 2 has a through hole 21, and the guide screw 32 slidably penetrates through the through hole 21. The number of the second clamping pieces 33 is two, the two second clamping pieces 33 are arranged oppositely, the first clamping piece 2 and the two second clamping pieces 33 are arranged adjacently in pairs, and the three clamping claws are used for clamping the end part of the bar 4.

Referring to fig. 2 and 4, the lead screw 32 is sleeved with an elastic member 321, two ends of the elastic member 321 are respectively connected to the base 3 and the first clamping member 2, and the elastic member 321 is preferably a spring. The elastic member 321 and the first nut 1 are movably abutted to two sides of the first clamping member 2, and when the first nut 1 pushes the first clamping member 2 to approach the second clamping member 33, the first clamping member 2 overcomes the elastic force of the elastic member 321 to compress the elastic member 321. Conversely, when the first nut 1 is moved in a direction away from the first clamping member 2, the first clamping member 2 slides along the lead screw 32 under the elastic force of the elastic member 321, i.e. the elastic member 321 is used for resetting the first clamping member 2.

The base 3 is further provided with an adjusting assembly 34, the adjusting assembly 34 includes a second nut 341 fixedly connected to the base 3 and an adjusting screw 342 movably connected to the second nut 341 in a matching manner, and the adjusting screw 342 is rotated and rotated relative to the second nut 341 so that the adjusting screw 342 moves relative to the second nut 341 along the axial direction thereof. The end of the adjusting screw 342 is movably connected to the first clamping member 2, and the adjusting screw 342 is rotated to push the first clamping member 2, so that the first clamping member 2 is always horizontally disposed.

Furthermore, one end of the first clamping member 2 abuts against the side wall of the bar 4, the other end is movably connected to the adjusting screw 342 in a matching manner, and the through hole 21 is formed in the middle of the first clamping member 2. The end of the adjusting screw 342 is provided with a connecting member 3421, the first clamping member 2 is provided with a groove 22 movably connected to the connecting member 3421, the shape of the groove 22 matches with the shape of the connecting member 3421, and preferably, the cross section of the connecting member 3421 is arc-shaped.

The first clamp 2 and the two second clamps 33 clamp only at the ends of the bar 4, which allows the cutting saw blade of the sawing machine to cut a bar 4 of thinner thickness (thickness refers to the distance between the two end faces of the bar 4).

To sum up, the utility model discloses a bar anchor clamps, be equipped with locating plate 31 on its base 3, lead screw 32 and second holder 33, the terminal surface butt of bar 4 in locating plate 31, locating plate 31 can restrict the degree of freedom of bar 4 promptly, lead screw 32 is located to first holder 2 activity ground cover, can adjust the position of first holder 2 on lead screw 32 through adjusting first nut 1 on the lead screw 32, make the equal butt of tip of first holder 2 and the tip of second holder 33 in the lateral wall of bar 4, in order to press from both sides tight bar 4, locating plate 31, first holder 2 and second holder 33 can restrict the degree of freedom of bar 4 jointly, ensure that this anchor clamps can stably centre gripping bar 4.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
