Abstract
The invention relates to a casting camshaft machining center locating device, in particular to a locating device suitable for simultaneous multi-station machining of a pin hole in the outer circle face of a journal, and belongs to the technical field of camshaft machining. The casting camshaft machining center locating device is mainly characterized in that the device is composed of a circumferential locating base and a circumferential locating block with a peach-shaped molded line matched with the molded line of a blank cam, the circumferential locating block above the circumferential locating base is connected in a vertical step hole in the center of the bottom of the circumferential locating base in a screwed mode through a bolt sleeved with a spring, and guide pins are inserted into holes, in the two sides of the bolt, of the circumferential locating base, wherein the holes correspond to the circumferential locating block. The cam peach shape of the circumferential locating block is completely matched with the molded line of the blank cam, locating precision is improved, the problem that the cam cannot be rounded is effectively solved, and therefore machining efficiency and quality can be improved.
Description
Technical field
The present invention relates to a kind of foundry goods camshaft machining center positioner, be applicable to pin-and-hole and be positioned at the positioner that the multistation on axle journal periphery processes simultaneously, belong to camshaft processing technique field.
Background technology
When engine assembly, alignment pin assembles through the hole on cylinder body and pinhole of camshaft, now determines the phase place (angle between pin-and-hole and nose) of camshaft.Air/fuel gaseous mixture enters engine and waste gas discharge engine all will pass through valve, as the cam shaft rotates, camshaft cam promotes valve makes it open, and valve spring is then responsible for valve to back into closed position, produces tremendous influence to the performance of engine under different rotating speeds.The pin-and-hole of camshaft is all on end face usually, the pin-and-hole of the camshaft product had now is positioned on axle journal periphery, machining center selects blank cam to locate as circumference when machining hole system, due to camshaft impact because of die joint in blank manufacture process, eave tile can be formed at nose position, the location of pin-and-hole phase place is had a great impact, finally can cause the not round-formed waste product of S-CAM grinder.
Summary of the invention
The object of this invention is to provide a kind of foundry goods camshaft machining center positioner, when solving existing machining center is positioned on axle journal periphery camshaft product at pin hole processing circumference location inaccurate cause mutually biased, S-CAM grinder not circle easily forms the deficiency of waste product, circumferential accurate positioning is ensured by the present invention, phase place zero deflection, improve positioning precision, effectively solve the defect that S-CAM grinder is not justified, thus improve working (machining) efficiency and quality.
The object of the invention is to be achieved through the following technical solutions, a kind of foundry goods camshaft machining center positioner, it is characterized in that, described device is made up of circumferential positioning base and the circumferential locating piece with the peach-shaped molded line coincide with blank cam profile, through the circumferential locating piece that cover has the bolt of spring to spin above it in the vertical shoulder hole of bottom center of circumference positioning base, in the hole that the circumferential positioning base of bolt both sides is corresponding with circumferential locating piece, insert guide finger.
Gap is had between described circumferential positioning base and circumferential locating piece.
On described circumferential locating piece, the two ends height of peach-shaped molded line differs.
The present invention is by selecting location blank camshaft mould polar coordinates lift by the molded line of circumferential locating piece, make the cam peach-shaped of circumferential locating piece completely identical with blank cam profile, positioning precision improves, effective solution S-CAM grinder not circle, positioning cam is selected becoming the blank in 180 ° of directions to locate with pin-and-hole by we simultaneously, reduce the workpiece of answering blank Action of Gravity Field to cause greatly to rotate, pin-and-hole phase place is inaccurate.The present invention has the following advantages: 1. the molded line of positioning tool selects blank camshaft mould polar coordinates lift, make the cam peach-shaped of frock completely identical with blank cam profile, positioning precision improves, 2. the blank cam orientation becoming 180 ° of directions with pin-and-hole is selected in circumference location, easy to setup, also efficiently solve because gravity and workpiece rotate the not round waste product problem of the S-CAM grinder caused in clamping process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1 circumferential positioning base, 2 circumferential locating pieces, 3 peach-shaped molded line, 4 blank cams, 5 bolts, 6 springs, 7 guide fingers.
Detailed description of the invention
Further illustrate the present invention in conjunction with the accompanying drawings and embodiments, as shown in Figure 1, the present invention is made up of with the circumferential locating piece 2 with the peach-shaped molded line 3 coincide with blank cam 4 molded line circumferential positioning base 1, through the circumferential locating piece 2 that cover has the bolt 5 of spring 6 to spin above it in the vertical shoulder hole of bottom center of circumference positioning base 1, in the hole that the circumferential positioning base 1 of bolt 5 both sides is corresponding with circumferential locating piece 2, insert guide finger 7.The effect of spring 6 allows circumferential locating piece 2 remain under spring force and the laminating of blank cam 4 surface, plays the effect of location; Now circumferential locating piece 2 can move up and down, and peach-shaped molded line 3 and the blank cam 4 of circumferential locating piece 2 fit tightly positioning workpieces, play circumferential positioning action, pin hole processing.Have gap between circumference positioning base and circumferential locating piece, use is interfered to prevent in gap, and on circumferential locating piece 2, the two ends height of peach-shaped molded line 3 differs, and requires to facilitate during clamping workpiece, territory, locating area envelope cam peach lumbar region.
Claims (3)
