Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

Example (b):

referring to fig. 1, the present embodiment provides a clamping apparatus for diamond production for clamping a diamond square sheet (hereinafter referred to as a sheet); comprises a base 1, wherein the upper wall of the base 1 is provided with a cutting marked line 11, wherein the cutting marked line 11 is arranged along the moving path of the cutting head of the cutting machine, in other words, the cutting head moves along the direction of the cutting marked line 11 when in cutting displacement.

Two slide rails 12 perpendicular to the cutting marked line 11 are fixedly installed on the upper wall of the base 1, and the slide rails 12 may be dovetail slide rails 12, or may be other types of slide rails 12.

A sliding seat 2 sliding along the length direction of the sliding rail 12 is slidably mounted on the two sliding rails 12, and the sliding seat 2 is perpendicular to the sliding rails 12; the slide carriage 2 is driven to slide by a driving mechanism 3 mounted on the base 1, specifically:

the driving mechanism 3 comprises a support 31 fixedly arranged on the front side of the base 1, a screw rod 32 which is in threaded connection and is arranged on the support 31 in a penetrating way, and a first hand wheel 33 fixedly arranged at the outer end of the screw rod 32; wherein the inner end of the threaded rod 32 is rotatably connected to the front side of the slide 2. The first hand wheel 33 drives the screw rod 32 to rotate, and then under the action of the thread of the support 31, the screw rod 32 performs axial displacement, so as to push the sliding seat 2 to displace along the length direction of the sliding rail 12, thereby adjusting the position of the sliding seat 2.

Two clamping blocks 4 which are arranged on the sliding seat 2 in a sliding mode are symmetrically arranged on the sliding seat 2, wherein V-shaped notches 41 are formed in the side walls of the two clamping blocks 4 on the opposite sides, and the included angle of each V-shaped notch 41 is a right angle.

The side of the clamp block 4 near the notch side of the V-shaped notch 41 is a smooth plane for clamping both sides of the sheet when the sheet is cut horizontally, as shown in fig. 6.

The upper wall of the sliding seat 2 is provided with a movable groove 21 extending along the length direction of the sliding seat 2; and a locking mechanism 5 which drives the two clamping blocks 4 to move towards opposite directions simultaneously is arranged on the sliding seat 2.

The locking mechanism 5 comprises a driving shaft 51 rotatably arranged in the movable groove 21, one end of the driving shaft 51 is rotatably connected to the wall of the movable groove 21, and the other end penetrates out of the movable groove 21 and is fixedly connected with a second hand wheel 52.

As shown in fig. 3, two thread segments with opposite thread directions are symmetrically arranged on the shaft wall of the driving shaft 51 in the movable groove 21; the two thread sections are both in threaded connection with sliding blocks 53 which are slidably arranged in the movable grooves 21, and each sliding block 53 is fixedly connected with one clamping block 4.

As shown in fig. 3, it is only necessary to rotate the second wheel 52 to rotate the driving shaft 51, so that the two sliding blocks 53 are driven to move in opposite directions by the two threaded sections, and the two sliding blocks 53 drive the two clamping blocks 4 to move in opposite directions; it can be seen that the sheet need only be placed on the slide 2 so that a set of diagonal corners of the sheet are aligned with the V-shaped grooves of the two clamping blocks 4, and then the two clamping blocks 4 are driven towards each other. Until the two angles of the sheet material are respectively abutted against the V-shaped grooves, so that one of the other opposite angles of the sheet material is positioned at the cutting station (one side of the cutting marked line 11), and the angle can be cut off only by controlling the cutting machine to start cutting, so that chamfering cutting is realized.

Referring to fig. 4, in order to control the cut-off amount of the chamfer more accurately, in the present embodiment, a positioning mechanism 6 is installed on a side of the cutting mark 11 away from the sliding seat 2, the positioning mechanism 6 includes a fixing seat 61 installed on the base 1, wherein the fixing seat 61 is located on a side of the cutting mark 11 away from the sliding seat 2; specifically, the fixing base 61 may be mounted on the base 1 by means of screw mounting.

Referring to fig. 5, a scale bar 62 extending in a direction perpendicular to the cutting mark 11 is fixedly mounted on the fixing base 61, wherein a scale 621 is disposed on an upper wall of the scale bar 62, and the upper wall of the scale bar 62 is not higher than the upper wall of the slide base 2.

A limiting block 63 which can slide along the length direction of the scale bar 62 is arranged on the scale bar 62 in a sliding way; the upper wall of the limiting block 63 is higher than the plane of the upper wall of the sliding seat 2.

Wherein, the side walls at the two sides of the scale bar 62 are both provided with sliding grooves 622 extending along the length direction of the scale bar 62; the lower parts of the two sides of the limiting block 63 are fixedly connected with sliding parts 631 which are slidably connected in the sliding grooves 622. The slide portion 631 slides in the slide groove 622.

A threaded through hole (not shown in the figure) vertically penetrating through the upper wall of the limiting block 63 is formed in the upper wall of the limiting block 63; a locking bolt 64 is screwed into the threaded through-hole, wherein the inner end of the locking bolt 64 abuts against the upper wall of the scale bar 62.

It can be seen that as the cutting head of the cutting machine travels along the path of the cutting reticle 11, the amount of chamfer cut of the sheet is approximately equal to the distance between the cutting reticle 11 and the stop 63, which can be read by the graduation marks 621 on the graduation stripe 62.

Thus, before cutting, the locking bolt 64 is firstly loosened according to the cutting amount of the chamfer to be cut, the limiting block 63 is moved until the limiting block 63 moves to the position with the required scale, the locking bolt 64 is screwed, the position of the limiting block 63 is locked, the sheet is clamped by the two clamping blocks 4 according to the steps described above, and then the screw 32 is rotated to push the sliding seat 2 to advance until the corner point of the front corner (the corner to be cut) of the sheet is abutted against the limiting block 63. Thus, the chamfer can be quantitatively cut off.

Above only the typical example of the utility model discloses, in addition, the utility model discloses can also have other multiple concrete implementation manners, all adopt the technical scheme that equivalent replacement or equivalent transform formed, all fall in the utility model discloses the scope of claiming.
