Description

PCB drill bit grinding clamp

Technical Field

The utility model belongs to the technical field of anchor clamps, especially, relate to a PCB bores and chews grinding fixture.

Background

The PCB drill bit is extremely important to grind, the standard drill bit is suitable for drilling processing of printed circuit boards, the raw material adopts hard alloy materials, the drill bit has the advantages of high hardness, high wear resistance, high strength, bending resistance and breakage resistance, the service life of the cutter is long, the cutting edge of the drill bit is sharp, cutting force can be reduced, the broken drill rate is reduced, the hole wall quality is improved, the conditions of board thickness, copper thickness, board structures and the like of the PCB produced by various board manufacturers are different, the drill bit is broken due to overlarge stress caused by too fast drilling speed, the production efficiency is reduced due to too slow drilling speed, and therefore the PCB needs to select the most appropriate drilling parameters according to specific conditions.

When the drill bit of the existing PCB is ground, the angle of the clamped drill bit is fixed, the use range of the drill bit grinding is influenced, the operation is complex, and the production cost is increased.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned problem that prior art exists, this application provides a PCB drill bit grinds anchor clamps.

The technical scheme of the utility model as follows:

the utility model provides a PCB drill bit grinding fixture, includes chuck A seat, and chuck B seat is connected to chuck A seat, and chuck B seat is supporting to have universal chuck, and universal chuck is equipped with clamping piece and lower clamping piece, goes up the clamping piece and sets up the through-hole down between the clamping piece, and the regulation elasticity screw is installed to universal chuck, and the inside of chuck B seat is equipped with precision bearing.

As a preferred embodiment of the present invention: the chuck A seat is connected with the induction pin through a set screw.

As a preferred embodiment of the present invention: the induction pin is connected with the set screw.

As a preferred embodiment of the present invention: the precision bearing is provided with a bearing cap.

As a preferred embodiment of the present invention: the chuck A seat is provided with a precision adjusting screw.

The utility model discloses profitable technological effect as follows:

the utility model relates to a PCB bores and chews grinding fixture through the last clamping piece of universal chuck and lower clamping piece cooperation, can carry out universal regulation to the drill point angle of clamping, has enlarged the application range that the PCB bore chews and grinds, and convenient operation can accurate regulation size, has ensured PCB's product quality.

FIG. 1 is a schematic view of the structure of the PCB drill grinding fixture of the present invention;

fig. 2 is an assembly diagram of the present invention.

Reference numerals are as follows: 1-universal chuck, 2-chuck A seat, 3-chuck B seat, 4-precision adjusting screw, 5-tightness adjusting screw, 6-set screw, 7-precision bearing, 8-positioning screw and 9-induction pin.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples. It is to be understood that the embodiments described are only some embodiments of the invention, and 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. 1-2, the present invention relates to a grinding fixture for a PCB drill: including chuck A seat 2, chuck B seat 3 is connected to chuck A seat 2, and chuck B seat 3 is supporting to have universal chuck 1, and universal chuck 1 is equipped with clamping piece and lower clamping piece, goes up the clamping piece and sets up the through-hole down between the clamping piece, and universal chuck 1 is installed and is adjusted elasticity screw 5, and chuck B seat 3's inside is equipped with precision bearing 7.

Specifically, the tightness adjusting screw 5 is a fastening piece for adjusting position change, can be used for preventing relative movement, is convenient to disassemble, can work in severe environment, has various structural forms and good universality and interchangeability, and can be used for adjusting the tightness of a drill point arranged on the universal chuck 1.

Specifically, the set screw 8 is machined by a numerically controlled lathe, has a smooth surface and accurate dimension, has a material performance grade of 8.8, and has the advantages of simple construction, good stress performance, fatigue resistance and no looseness under the action of dynamic load.

Specifically, the precision of the precision bearing 7 is controlled within 1 μm, and the precision of the precision bearing is required to be very high in size precision and shape precision with a matching machine part, particularly the precision of a matching surface is controlled within the same level as that of the bearing, so that the cost can be saved, the service life can be prolonged, the maintenance is not needed, and the operation reliability is improved.

The chuck A seat 2 is connected with the induction pin 9 through the positioning screw 8, and has the advantages of strong anti-interference capability, high sensitivity, high reliability and quick response; the induction pin 9 is connected with the set screw 6, does not damage the surface of the part and can transfer larger load; the precision bearing 7 is provided with a bearing cover which can prevent dust and foreign matters from invading the roller path of the rolling body; the chuck A seat 2 is provided with an adjusting precision screw 4, and the operation is convenient.

To sum up, the utility model relates to a PCB bores and chews grinding fixture, last clamping piece and lower clamping piece cooperation through universal chuck can carry out universal regulation to the drill point angle of clamping, has enlarged the application range that the PCB bore and chews the grinding, can accurate regulation size, has ensured PCB's product quality, convenient high efficiency.
