Description
Technical field
The utility model relates to a kind of machine-building special fixture, the special milling fixture of specifically a kind of brake valve upper shell upper surface processing.
Background technology
Special fixture is a certain procedure processing of part and manufacturing and designing, and uses in the production relatively stable at product, batch is larger; Labour intensity when it can reduce work effectively in process of production, raise labour productivity and obtain higher machining accuracy.
Fraise jig is mainly used in plane, groove, spline and various forming surface on processing parts, is one of the most frequently used fixture.Primarily of positioner, clamping device, clamp body, Connection Element, tool setting element composition.During Milling Process, cutting force is comparatively large, is again interrupted cut, and vibration is comparatively large, and therefore the clamping force of fraise jig requires comparatively large, and fixture rigidity, requirement of strength are all higher.
The fixture that use is in the past common, because of the difference of workpiece size, cause clamping extremely inconvenient, loading, unloading workpiece is very difficult, and production efficiency is very low, and frequently clamp by hand, the labour intensity of workman is quite large.
Utility model content
For the deficiency on plain clamp clamping workpiece, the special milling fixture that the utility model provides a kind of brake valve upper shell upper surface to process, this workpiece adopts two vertical plates, mandrel and rhombus pin integrated positioning scheme on clamp body, and plane and two pits targeting scheme, adopt the cooperation of mandrel, pad and nut, can Quick holding part be realized.
The purpose of this utility model can be achieved through the following technical solutions:
A special milling fixture for brake valve upper shell upper surface processing, comprises bindiny mechanism, detent mechanism, clamp system and tool setting device,
Described detent mechanism comprises and is fixed on two relative two vertical plates of position on clamp body, wherein, a two vertical plates is provided with the mandrel corresponding with part valve opening and rhombus pin;
Described clamp system comprises the nut be arranged on for clamping parts on mandrel;
Described tool setting device comprises the pin and screw that feeler block are installed to another two vertical plates upper end.
Described mandrel, rhombus pin respectively with two vertical plates interference fit.
Described bindiny mechanism comprises and clamp body is fixed on T-slot bolt on milling machine and directional bond.
Pad is provided with between described clamping parts and nut.
Clearance gauge is provided with above described feeler block.
The beneficial effects of the utility model: the utility model clamping is solid and reliable, centering precision is high, labor intensity alleviates greatly, and special milling fixture major part is all standard component, is convenient to choose, and can obtain the achievement of low cost high yield.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is that the utility model faces structural representation;
Fig. 2 is the utility model plan structure schematic diagram;
Fig. 3 is the utility model brake valve design of part schematic diagram.
Detailed description of the invention
Brake valve is the primary control in running brakes, in the braking procedure and dispose procedure of double loop primary brake system, realize sensitive servo antrol.As shown in Figure 1, Figure 2, Figure 3 shows, the special milling fixture of a kind of brake valve upper shell upper surface processing, comprises bindiny mechanism, detent mechanism, clamp system and tool setting device.
The bindiny mechanism of fixture and milling machine is made up of with milling machine T-slot bolt 9, directional bond 10.First by T-slot bolt 9, directional bond 10 is connected with the T-shaped groove on milling machine, realizes the fixing of whole clamp body 1.
Detent mechanism is made up of two vertical plates 13, mandrel 2 and rhombus pin 3 on clamp body 1, and the locate mode of plane and two pits can guarantee the fixing of fixture.Again by mandrel 2, rhombus pin 3 is connected with clamp body 1 by temperature differential method or plunging, because do not need frequent dismounting, therefore selects interference fit.
Clamp system is made up of pad 11, nut 12, part 8 is passed through the constraint clamping of two axialities on fixture, puts into pad 11 successively again, nut 12 clamps after installing.
Tool setting device is made up of pin 4, screw 5, clearance gauge 6, feeler block 7.Feeler block 7 by pin 4, screw 5 is respective installs to for a pair on two vertical plates, then place up after clearance gauge 6 carries out tool setting and can carry out milling upper surface.
Conventional method adopts universal fixturing clamping workpiece, and class yields poorly, and adopt this novel rear class output to significantly improve, production efficiency obviously promotes at double.This Novel brake valve end face processing special milling fixture is widely used in the processing of brake valve upper surface in machining manufacturing industry, to realize the self-centering quick-clamping of workpiece.
The utility model utilizes two vertical plates, nut and pad Clamp blocks on mandrel, rhombus pin, clamp body, has reliable operation, efficiency is high, and handling safety, laborsaving, clamping are rapidly and be convenient to the feature of manufacture and maintenance.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
