Therefore, the circuit board is smaller and smaller, the contact points on the circuit board are smaller and smaller, the distance between the contact points is narrower and narrower, and the passing current is larger and larger. Conventional test needle is because the easy atress inequality of structural constraint leads to collapsing absolutely, intensity can't satisfy more meticulous test requirement, for this the sheet needle that is used for the test of booth clearance has appeared on the market, it is most advanced including integrated into one piece's contact in proper order, the connecting portion and the female end of wave line type, the whole of sheet needle is slice, thickness is 0.1mm to 1mm, make the installation more stable and adapt to the test environment of more booth apart from through slice structure, the connecting portion of wave line type can absorb the impact force and prevent collapsing absolutely. As shown in fig. 1, mounting of the wafer pins requires a plurality of small-spaced connecting grooves for clamping and fixing, most of the conventional connecting groove processing methods are milling cutter processing and linear cutting processing, wherein the fixing clamp is made of an insulating non-metallic material in order to avoid interference of current between the wafer pins, so that the wire cutting processing cannot be used; in addition, the thickness of the blade needle is small, the gap is small, so that a milling cutter with a specific size can be used for machining, the blade length of the milling cutter is far larger than the diameter of the blade part due to the limitation of the depth of the groove, the blade part is easy to break, only one connecting groove can be machined in a single machining process, if the clamp needs to be grooved on two sides, the number of the connecting grooves is large, the machining time of the single clamp is long, and the production cost is too high.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a sheet type machining cutter and a machining operation method thereof, wherein the sheet type machining cutter can perform small-spacing grooving, and is low in machining cost, high in efficiency and stable in work.
The technical scheme adopted by the invention is as follows: the piece formula processing cutter includes handle of a knife, fixed head and a plurality of saw bit, and is a plurality of the saw bit is all set on the handle of a knife, the fixed head with the handle of a knife cooperation is with a plurality of the saw bit is pressed from both sides tightly, the fixed head through fixed screw with handle of a knife fixed connection, adjacent two all be provided with the spacer between the saw bit.
It is thus clear that by above-mentioned scheme, through adopting the saw bit to rotate to saw cut the processing that carries out the spread groove, set up the spacer simultaneously and make adjacent two leave the interval between the saw bit, and then process out the spread groove of little interval on anchor clamps. A plurality of connecting grooves are machined simultaneously by arranging a plurality of saw blades simultaneously, and the production efficiency is effectively improved. The saw blade is adopted for slotting, so that the phenomenon that the cutter is broken by lateral force due to the fact that the diameter of the machined cutter is small in the machining process can be effectively avoided, and meanwhile, the production cost of the cutter is reduced. When the saw cutting machine is used for saw cutting, the saw blades can be tightly abutted to each other through the side walls of the connecting grooves, no gap exists, the phenomenon of cutter bouncing and cutter shaking cannot be generated, the work is stable, the damage is not easy to damage, and the qualified rate of processed finished products is high. Due to the adoption of laminated sawing, the combination of the blades is flexible and variable, the thickness of the grooves is from 0.1mm to 1mm, the number of the grooves is not limited, and more complicated clamps can be sawed.
According to a preferable scheme, the fixing head is provided with a through hole matched with the maximum diameter of the thread part of the fixing screw, the through hole is a stepped hole, and the edge of one end, far away from the handle, of the through hole is in a chamfer shape.
The scheme shows that the fixing head is further limited by the fixing screws through the design of the chamfer shape, and the radial runout caused by production errors is reduced.
According to a preferable scheme, the cutter handle is a stepped shaft, the saw blades are provided with connecting holes matched with the small-diameter end of the cutter handle, and the saw blades are sleeved at the small-diameter end of the cutter handle.
One preferred scheme is that the saw blade is disc-shaped, a plurality of saw teeth are arranged on the outer edge of the saw blade, and the thickness of the saw blade is 0.1mm to 1 mm.
According to the scheme, the thickness of the saw blade is set according to the requirement of a product.
The processing operation method comprises the following steps:
A. assembling the sheet type machining cutter according to the number of the sheet pins to be clamped by the clamp, the thickness of the sheet pins and the distance between the clamping grooves;
B. sequentially loading the saw blades with corresponding thicknesses into the cutter handle, sleeving the fixing head on the cutter handle, enabling the fixing head to be matched with the step on the cutter handle to limit all the saw blades, and screwing the fixing screw to enable the fixing head to tightly press all the saw blades;
C. clamping the assembled sheet type machining cutter on machining equipment;
D. carrying out finish machining on five surfaces of the clamp and rough machining on the grooving surface by an external numerical control machine tool, and driving the sheet type machining cutter to sequentially carry out primary grooving with the depth of 0.2mm, secondary grooving with the depth of 0.5mm and intermittent sawing on the grooving surface of the clamp by machining equipment, wherein the sawing depth of the remaining part is greater than the preset grooving depth minus the grooving depths of the first two times;
E. and after the grooving is finished, milling the grooving surface to enable the grooving depth to reach a set value.
According to the scheme, all grooves of the same grooving surface are machined at one time in a transverse saw cutting mode, and the machining time is short. During sawing, the saw blades can be tightly abutted without gaps, the phenomenon of cutter bouncing and cutter shaking cannot be caused, and the qualified rate of processed finished products is high. In addition, because the laminated sawing is adopted, the blade combination is flexible, the grooves with the thickness of 0.1mm to 1mm can be sawed simultaneously, the number of the grooves is not limited, and more complicated parts can be sawed. Compared with the traditional milling process, the machining cost is lower, the requirement on the strength of the cutter is lower, the production cost of the cutter is low, and meanwhile, the machining efficiency is high. And meanwhile, the milling of the grooved surface subjected to rough machining can ensure the surface flatness of the cover surface, and meanwhile, the machining allowance is provided, so that a remediation space is provided for errors generated by machining.
Preferably, the step D further includes the following steps: slotting the finish machining face of the clamp far away from the slot face, and sequentially slotting by 0.2mm of depth for the first time, slotting by 0.5mm of depth for the second time and intermittently sawing the rest set depth by the sheet type machining cutter.
According to the scheme, for the clamp with the grooves on the two sides, the groove is firstly formed in the finish machining surface of the clamp far away from the groove surface, the groove on the existing finish machining surface is used as a reference, and then the allowance of the rough machining surface is utilized to enable the product to correct errors, so that the quality of the product is guaranteed.
