The milling machine fixture used for machining the sleeve end face straight chute is characterized in that levers (10) are arranged below the fixture body (2) and between the rotating rods (5) and the right side of the fixture body (2) is provided with a tool setting rod (7). According to the milling machine fixture, different cylindrical pins are selected to achieve milling processing of sleeve parts of similar shapes and different sizes, the production preparation cycle is shortened, two-point linkage axial clamping is conducted on sleeves through a lever mechanism, the sleeves can be assembled and disassembled rapidly and reliably, labor intensity of workers is relieved, and work efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of fraise jig, relates in particular to a kind of for processing the fraise jig of sleeve end face straight trough.
Background technology
The sleeve part in batch that I take charge of processing as shown in Figure 1.This part material is 45 steel, annual production is about 10 000 left and right, because this batch of part shape is similar, size is different, its cylindrical, the processing of end face and endoporus can adopt scroll chuck clamping turning processing, and end face straight trough is necessary for Milling Process, therefore, must design Holding appliance specially for milling machine, but find aborning, though special fixture has guarantee part processing precision, the advantages such as compact conformation and rigidity are strong, but it is special that it can only be the machining of a certain size parts, in the time that accessory size changes, just need to again make other special fixture, and it is long to redesign the manufacturing cycle, the amount of labour is large.
Utility model content
For the problems referred to above, I take charge of the fraise jig that has designed a kind of new structure, and this fixture, based on modular fixture principle design, can overcome the deficiency of special fixture effectively, can meet machining accuracy, has again certain flexibility.In production, greatly improve economic benefit, improved the enterprise product market competitiveness.
The purpose of this utility model is achieved through the following technical solutions:
A kind of for processing the fraise jig of sleeve end face straight trough, comprise clamp body (2), support nail (3), pressing plate (4), dwang (5), spring (8) and positioning seat (9), described support nail (3) and dwang (5) quantity are 2, be arranged symmetrically in the two ends of clamp body (2), on dwang (3), be socketed with spring (8), spring (8) top is provided with pressing plate (4), pressing plate (4) end support is on support nail (3), innovation is: described clamp body (2) below, between dwang (5), be provided with lever (10), described clamp body (2) the right is provided with knife bar (7).
Further, described lever (10) is connected on dwang (5) by pin, clamp body (2) bottom is provided with bearing (12), bearing (12) plays a fulcrum, can make lever (10) rotate around bearing (12), realize left and right two end clamp plates (4) interlock of sleeve is clamped.
Further, described positioning seat (9) lower end is provided with alignment pin, alignment pin and positioning seat are designed to one, positioning seat (9) is connected on clamp body (2) by alignment pin, positioning seat (9) upper end is provided with straight pin, and it is upper that straight pin is movably connected in positioning seat (9), in the time of sleeve diameter of bore change in size, by changing straight pin, can ensure the positioning precision of another batch of sleeve.
Further, described knife bar (7) is threaded connection at clamp body (2) upper, upper with being threaded in clamp body (2) to knife bar (7), can facilitate tool setting, thereby meet the status requirement of cutter with respect to part, the crudy of guarantee sleeve.
Compared with prior art, the beneficial effects of the utility model are:
The utility model, by selecting different straight pins, can be realized the sleeve part Milling Process that shape is similar, size is different, has shortened the production preparatory period.Adopt leverage to carry out 2 interlock axial grips to sleeve, handling sleeve is reliable rapidly, has reduced workman's labour intensity, has greatly improved production efficiency.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is further elaborated.
A kind of for processing the fraise jig of sleeve end face straight trough, comprise clamp body (2), support nail (3), pressing plate (4), dwang (5), spring (8) and positioning seat (9), described support nail (3) and dwang (5) quantity are 2, be arranged symmetrically in the two ends of clamp body (2), on dwang (3), be socketed with spring (8), spring (8) top is provided with pressing plate (4), pressing plate (4) end support is on support nail (3), described clamp body (2) below, between dwang (5), be provided with lever (10), described clamp body (2) the right is provided with knife bar (7).
When the utility model uses, as shown in Figure 2, clamp body (2) is fixed on milling machine table (1), be provided with left side pressing plate and right side pressing plate in clamp body (2) bilateral symmetry, the lower end of supporting nail (3) is arranged on clamp body (2) by screw thread, the upper end of supporting nail (3) is supported on the outer end of left side pressing plate, the lower end of left side dwang is connected with one end of lever (10) with after clamp body (2) through the middle part of left side pressing plate, upper end at left side dwang is provided with clamp nut, the other end of lever with through the middle part of right side pressing plate and the dwang lower end, right side of clamp body, upper end at right side dwang is provided with nut, bearing (12) is arranged on clamp body (2) goes up and is supported on the middle part of lever (10), positioning seat (9) is arranged on clamp body (2) and goes up and be positioned at left side pressing plate and right side pressing plate middle section, and the straight pin suitable with sleeve (6) is arranged on positioning seat (9).Upper with being threaded in clamp body (2) to knife bar (7), can facilitate tool setting, thereby meet the status requirement of cutter with respect to part, ensure the crudy of part.
Operation principle of the present utility model is: before processing, first according to the radially basic size in the sleeve part hole of required processing, design processing column pin (hole in piece part radially basic size changes time, need to change straight pin), then on positioning seat (9) and straight pin (being blocked by the sleeve in figure), complete location with sleeve (6) bottom surface and endoporus; Fastening nut, makes the left side downward clamp sleeve of pressing plate (6), and left side dwang drives lever (10) to clockwise rotate around bearing (12) simultaneously, makes right side dwang drive right side pressing plate interlock clamp sleeve (6).After the straight trough of sleeve (6) machines, unscrew nut, by the spring (8) on dwang (5), sleeve is unclamped, can realize freely loading and unloading of sleeve (6).In the time that the axial dimension of sleeve (6) seal face changes, need adjust in advance the size of stretching out of supporting nail (3), and suitably adjusting nut is horizontal pressing plate substantially.
