Description

Clamp for cutting PCD (Poly Crystal Diamond) cutter

Technical Field

The utility model relates to a cutting jig especially relates to a anchor clamps that cutting PCD sword was used.

Background

The PCD cutter is a polycrystalline diamond cutter, has the characteristics of high hardness, high compressive strength, good heat conductivity, good wear resistance and the like, and can obtain high processing precision and processing efficiency in high-speed cutting. In the process of manufacturing a PCD cutter, the PCD cutter is fixed to a jig and cut using a laser cutter to form various grooves.

However, most of the existing clamps are integrally formed, and are only suitable for positioning one type of PCD cutter, and the cutting position is relatively fixed, so that the universality is poor.

SUMMERY OF THE UTILITY MODEL

The utility model discloses technical scheme is to above-mentioned condition, provides a anchor clamps that cutting PCD sword was used in order to solve above-mentioned problem, anchor clamps include: the positioning device comprises a female positioning seat, a secondary positioning seat, a female screw and a secondary screw, wherein the female positioning seat is provided with a female positioning channel and a female thread groove, the female positioning channel extends from the front surface to the rear surface of the female positioning seat, the female thread groove extends from the upper surface of the female positioning seat to the female positioning channel, a part of the secondary positioning seat is positioned in the female positioning channel, the female screw is meshed with the female thread groove, the female screw is in contact with the secondary positioning seat, the secondary positioning seat is provided with a secondary positioning channel and a secondary thread groove, the secondary positioning channel extends from the front surface to the rear surface of the secondary positioning seat, the secondary thread groove extends from the upper surface of the secondary positioning seat to the secondary positioning channel, and the secondary screw is meshed with the secondary thread groove.

Furthermore, the female positioning channel is an inclined channel, and an included angle between the female positioning channel and the horizontal plane is 20-60 degrees.

Further, the height of the female positioning channel is greater than that of the sub-positioning seat.

Further, the lower extreme of female positioning seat has two backup pads, the backup pad has the support screw hole.

Further, the lower end of the sub-positioning channel is a tip.

After the technical scheme is adopted, the beneficial effects of the utility model are that:

1. because the PCD sword is fixed in the sub-positioning seat through the mode of locking the screw, consequently to the PCD sword of different sizes, all can adapt to through the degree of locking of adjustment screw, the commonality is better.

2. Because the PCD cutter is mainly fixed in the secondary positioning seat, even if the secondary positioning seat is abraded in the using process, the primary positioning seat does not need to be replaced, and the cost is saved.

Detailed Description

It is specifically noted that, in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise; the meaning of "several" is at least one. All directional indicators (such as up, down, left, right, front, and rear … …) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, and the like in a specific posture, and if the specific posture is changed, the directional indicator is changed accordingly.

The technical solution of the present invention is further described below by way of examples:

the utility model provides a anchor clamps that cutting PCD sword was used, it is shown to combine figure 1~5, above-mentioned anchor clamps include: the female positioning seat comprises a female positioning seat 1, a male positioning seat 2, a female screw 3 and a male screw 4, wherein the female positioning seat 1 is provided with a female positioning channel 11 and a female thread groove 12, the female positioning channel 11 extends from the front surface to the rear surface of the female positioning seat 1, the female thread groove 12 extends from the upper surface of the female positioning seat 1 to the female positioning channel 11, a part of the male positioning seat 2 is positioned in the female positioning channel 11, the female screw 3 is meshed with the female thread groove 12, the female screw 3 is in contact with the male positioning seat 2, the male positioning seat 2 is provided with a male positioning channel 21 and a female thread groove 22, the male positioning channel 21 extends from the front surface to the rear surface of the male positioning seat 2, the female thread groove 22 extends from the upper surface of the male positioning seat 2 to the male positioning channel 21, and the male screw 4 is meshed with the male thread groove 22.

When the clamp is used, firstly, the PCD cutter is placed in the sub-positioning channel 21 of the sub-positioning seat 2, then the PCD cutter is fixed by locking the sub-screw 4, then the sub-positioning seat 2 is placed in the main positioning channel 11 of the main positioning seat 1, then the sub-positioning seat 2 is fixed by locking the main screw 3, and finally the PCD cutter is cut by using a laser cutter.

The PCD knives are fixed in the sub-positioning seats in a screw locking mode, so that the PCD knives of different sizes can be adapted by adjusting the locking degree of screws, and the universality is better.

In addition, at the in-process of cutting PCD sword, the condition of wearing and tearing anchor clamps can take place occasionally the utility model discloses in, because the PCD sword is mainly fixed in sub-positioning seat, even consequently sub-positioning seat produces wearing and tearing in the use, also need not change female positioning seat, practice thrift the cost.

Specifically, the female positioning channel 11 is an inclined channel, and an included angle theta between the female positioning channel 11 and the horizontal plane is 20-60 degrees. Through the setting, be the tilt state after the fixed completion of PCD sword, the vertical downcut of laser sword compares with the horizontality, under the condition that the laser sword removed the same fore-and-aft distance, can cut bigger area, so cutting control's precision is higher.

More specifically, the height H1 (i.e. the distance between the upper surface and the lower surface) of the female positioning passage 11 is greater than the height H2 of the child positioning socket 2. The above-mentioned dimension arrangement can make the female positioning passage 11 suitable for a plurality of different sizes of the child positioning seats 2.

Specifically, the lower end of the female positioning seat 1 has two support plates 13, and the support plates 13 have support threaded holes 14. The worker can fix the two supporting plates 13 on the worktable of the cutting device by means of locking screws to fix the female positioning seat 1.

Specifically, the lower end of the sub-positioning passage 21 is pointed. The handle of the PCD cutter is generally cylindrical, and the lower end of the sub-positioning channel 21 is arranged to be pointed compared with the cylindrical channel, so that a buffer space can be provided for the handle of the PCD cutter. Specifically, since the PCD cutter needs to be heated and softened during the cutting process, and a vertical downward force is applied during the cutting process, the PCD cutter is provided with a buffer space to avoid deformation caused by excessive compression.

The above-mentioned embodiments are merely preferred examples of the present invention, and do not limit the scope of the present invention, so all equivalent changes or modifications made by the structure, features and principles of the present invention should be included in the claims of the present invention.
