Abstract
The utility model discloses a lead frame press die transmission column grinding fixture. A frock clamp for the grinding machine. Location and the fixed problem of transmission column in abrasive machining is solved to its purpose, realizes pinpointing with reliable fixed, guarantees grinding precision, and then put forward lead frame punching precision. The utility model discloses constitute by locating plate and locking screw. The locating plate is box -like spare, and the system has the parallelogram locating hole above it, and the both sides face sets up corresponding locking screw. After transmission column packs the locating hole into, screw up the screw, can pinpoint and reliable fixing. The utility model discloses an important auxiliary of lead frame press die for it uses to play to pass the masterpiece in the press die.
Description
Technical field
This utility model is related to grinding machine frock clamp, specifically lead frame stamping die force-transmitting pole clamp.
Background technology
Lead frame is the chip carrier of semiconductor integrated circuit, is important base components in telecommunication industry, its making
Method has pressing and two kinds of etching method, and pressing application is at most.Punching press adopts high velocity ram machine and blanking die in making, raw
After continuous production some in product, grinding tool weares and teares, and leads to the problems such as product is overproof, and waste material backfills, needs mould is ground
Mill is repaired.Change due to grinding rear mold closure height, so will be ground repairing to the auxiliary component in mould simultaneously
Reason.Force-transmitting pole is the important auxiliary of transmission power, and its dimensional accuracy is very big on Product Precision impact, and its usage quantity is big, one pair
More than 20 are contained in mould.These force-transmitting poles must assure that end face is smooth and contour, wants clamped one time on grinding machine during grinding
Complete.And existing clamp is the magneticaction clamping by means of grinder chuck, because grinder chuck size is big in practical operation
And power transmission column diameter little it is impossible to reliably fixing and affect grinding accuracy, thus affecting the punching precision of lead frame.So needing
The clamp of force-transmitting pole is improved.
Content of the invention
This utility model provides a kind of lead frame stamping die force-transmitting pole clamp, by positioning and being total to of retaining mechanism
Same-action ensureing the grinding accuracy of force-transmitting pole, thus ensureing the punching quality of lead frame.
The technical solution of the utility model is as follows：Lead frame stamping die force-transmitting pole clamp includes keeper, described
Keeper is location-plate, and location-plate is box part, is formed with several location holes thereon, in order to lay force-transmitting pole, location-plate on box face
Two sides arrange several lock-screws, and the quantity of lock-screw is consistent with location hole, and its position is corresponding with location hole, works as force-transmitting pole
After loading location hole, tighten lock-screw and fixed.This fixture is placed on grinding machine and can be ground processing.
The beneficial effects of the utility model are：1st, structure is simple, easy to use, low cost of manufacture；2nd, due to clamped one time
Force-transmitting pole four sides stress after positioning and clamping, therefore uniform force, positioning is reliable, can be good at ensureing force-transmitting pole grinding quality,
And then be conducive to improving the punching quality of lead frame product；3rd, the location hole on location-plate can be multiple, a location hole
In can fill multiple force-transmitting poles, production efficiency is high, can meet the needs of production in enormous quantities.

Drawing explanation：In Fig. 2：1- force-transmitting pole 2- location-plate 3- lock-screw
Specific embodiment
Specific embodiment of the present utility model is described below in conjunction with the accompanying drawings, as shown in Fig. 2 this utility model includes positioning
Plate 2 and lock-screw 3, location-plate 2 is box part, and upper box face is formed with 5 location holes, and location hole is parallelogram, parallel
The less interior angle of tetragon, towards the two sides of location-plate 2, location-plate 2 two side arranges lock-screw 3, lock-screw 3
Quantity is consistent with positioning hole number, and its position interior angular range little with parallelogram location hole is corresponding.When force-transmitting pole 1 loads positioning
Kong Hou, tightens lock-screw 3, threaded end crown post force-transmitting pole 1, makes the surface uniform stressed of four force-transmitting poles 1, positioning fixation can
Lean on, will not swing in grinding, thus ensureing grinding accuracy.The stress of force-transmitting pole is as shown in Figure 3.
This utility model use state in a mold is as shown in Figure 1.
