Detailed Description

The technical solutions in the embodiments of the present invention are described below clearly and completely, 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, the present embodiment provides a sawing machine clamp convenient and fast to adjust, which includes a base 1, wherein the base 1 is provided with two sliding grooves along a length direction, the base 1 is provided with two opposite clamping members 2, and the clamping members 2 have sliding portions, and are slidably connected with the sliding grooves through the sliding portions; the base 1 is internally provided with a driving structure for driving the two clamping pieces 2 to approach to or separate from each other, in this embodiment, the driving structure is specifically a stud in threaded connection with the two clamping pieces 2, and is driven to rotate manually or by a motor so as to drive the two clamping pieces 2 to act, so that the effect of clamping a workpiece is realized.

In the application of the sawing machine, especially for the bar-shaped irregular object, such as a whole section of tree trunk, when it is not a straight cylinder, it is difficult to clamp it in the radial direction only by two clamping members 2, and the clamping surface of the clamping members 2 is a plane, so that it is difficult to clamp the irregular bar in the desired direction, and the bar is easy to shift due to uneven force, which affects the angular position of sawing, as shown in fig. 3.

In this embodiment, the clamping members 2 are further provided with a structure for adjustment, specifically, a plurality of slots 21 are formed in two opposite walls of the two clamping members 2, in this embodiment, three slots 21 are respectively formed in the two clamping members 2, and the two clamping members are opposite to each other; the clamping device is characterized in that a supporting block 31 is arranged in the open groove 21, two opposite side walls of the two clamping pieces 2 are fixedly provided with telescopic pieces 3 corresponding to the open groove 21, and the telescopic ends of the telescopic pieces 3 extend into the open groove 21 and are fixedly connected with the supporting block 31.

Wherein, the telescopic member 3 includes but not limited to a cylinder, a cylinder or an electric push rod, etc., providing a stable telescopic function with a certain strength.

An irregular long workpiece is placed on the base 1 according to a required machining position angle, the workpiece is located between the two clamping pieces 2, the two clamping pieces 2 are close to lightly clamp the workpiece without moving the workpiece, at the moment, the clamping surfaces of the clamping pieces 2 and the workpiece have positions which cannot be contacted, the expansion and contraction of the expansion piece 3 are controlled to enable the abutting blocks 31 located at the positions to extend out of the grooves 21 to abut against the workpiece to form support, and then the workpiece is clamped at the required machining position through the combined action of the clamping pieces 2 and the abutting blocks 31, and the reference figure 3 shows that.

In order to ensure that the abutting block 31 is stably contacted and clamped with the workpiece, a plurality of anti-slip ribs 32 are arranged on the abutting surface of the abutting block 31 abutting against the workpiece, so that the friction force on the surface of the workpiece is increased.

In another embodiment, the telescopic end of the telescopic member 3 is hinged to the middle of the abutting block 31, the side wall of the telescopic end is connected with two springs 33 up and down oppositely, the free ends of the two springs 33 are connected to the upper side and the lower side of the abutting block 31 respectively, and when the abutting block 31 abuts against the surface of a workpiece, the abutting block rotates to a certain extent according to the shape of the surface of the workpiece, so as to increase the contact area with the workpiece and increase the clamping strength and stability, as shown in fig. 2.

It is necessary to supplement, in order to facilitate the adjustment of the position and the angle of the workpiece and reduce manual operations, an index plate 11 is disposed in the middle of the base 1, the index plate 11 is rotatable relative to the base 1, and a motor for driving the index plate 11 to rotate is disposed in the base 1; the upper wall of the indexing disc 11 is flush with the upper wall of the base 1; a plurality of positioning holes 12 for mounting positioning pieces are formed in the indexing disc 11, the positioning pieces can be bolts, and bolt caps are positioned on the indexing disc 11 by screwing the positioning pieces into the positioning holes 12; according to the size of the workpiece, bolts are screwed into the corresponding positioning holes 12, so that when the workpiece is placed on the index plate 11, the bolts abut against the workpiece from the side edge, that is, the stability of the workpiece is improved, and when the index plate 11 rotates, the workpiece can be effectively driven to rotate through the bolts, so that the angle position can be adjusted.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
