Abstract
The invention discloses a technical equipment positioning press cake used for processing the end surface of an automotive engine cylinder block, belonging to the technical field of machining. The technical equipment positioning press cake is composed of a connecting block and a cone frustum press cake, wherein the connecting block is connected with a fixture, and the cone frustum press cake is respectively connected with the press cake and the automotive engine cylinder block. The technical equipment positioning press cake is suitable for processing, positioning and pressing the end surface of the automotive engine cylinder block, has the advantages of simple structure and high strength and is easy to manufacture. In the milling process, a cutter does not colloid with the positioning press cake so as to accurately position the cylinder block, and thus the technical equipment positioning press cake performs the action on improving production efficiency.
Description
Technical field
What the present invention relates to is the technological equipment in a kind of Machining Technology field, specifically a kind of technological equipment location briquetting for automobile engine cylinder body end face processing.
Background technology
After the motor cylinder casting moulding, carry out roughing, semifinishing and fine finishining to its front and rear end, satisfying the matching requirements of front and rear end, and require certain machining accuracy and crudy.For crudy and the production efficiency that improves front/rear end, the feed path of its operation is optimized, during according to the new route feed after optimizing, cutter and the collision of locating briquetting can occur, thereby the design of location briquetting will not satisfied and the cutter collision, and can play the requirement of accurate location.
In actual production, often the roughing of engine cylinder-body will be adopted thick benchmark, and the locating piece on the anchor clamps will satisfy the requirement of processing technology like this, not only will satisfy the requirement of locating surface on the cylinder body on the external form, and the intensity of locating piece also will guarantee.For automatic production line, the improvement of locating piece is not only wanted so that be convenient to change, and does not affect production efficiency.
When the engine cylinder-body production technology being optimized improvement, associated technological equipment also will redesign or improve, and satisfies the requirement that technological equipment carries out smoothly to explained hereafter with this.
Find through the retrieval to prior art, existing most technological equipments location briquetting, the Chinese invention patent publication number is " complex surface glue-joint process tool positioning block " that CN101462362A is delivered by Zhu's three low-priced grades, belong to the Aircraft tooling designing technique, relate to a kind of improvement to complex surface glue-joint process tool positioning block.But do not relate to a kind of improvement of technological equipment location briquetting of automobile engine cylinder body end face processing.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of technological equipment location briquetting for automobile engine cylinder body end face processing is proposed, be applicable to engine cylinder-body end face processing positioning compression, simple in structure, be easy to make, intensity is high, the requirement that cutter does not collide with the location briquetting in the milling process, thereby reach the accurate location to cylinder body, for effect has been brought into play in the raising of production efficiency.
The present invention is achieved by the following technical solutions, the present invention by the contiguous block that is connected with anchor clamps be connected the round platform compact heap that is connected with engine cylinder-body with contiguous block and form.
Described round platform compact heap is quadrant platform structure, and the round platform top half-angle of this round platform compact heap and the tool cutting edge angle of face milling cutters be complementary angle each other.
The bottom surface diameter of described round platform compact heap is the twice of optimization after advancing path arc section radius (being the face milling cutters cutter radius) with the difference of face milling cutters radius of clean-up; The upper bottom surface diameter is long-pending twice poor of cotangent value of the tool cutting edge angle of the thickness of bottom surface diameter and round platform compact heap and face milling cutters.
Described round platform compact heap bottom surface and engine cylinder-body processing end face are affixed.
The present invention adopts round platform compact heap structure, has following advantage: the compression area of compact heap is large, thereby makes the intensity of compact heap obtain enhancing, and is more accurate to the location of cylinder body; According to the feed path requirement after optimizing, when cutter at briquetting position, location through out-of-date, with location briquetting collision, thereby reach accurate location to cylinder body; The present invention is applicable to engine cylinder-body end face processing positioning compression, and is simple in structure, is easy to make, and intensity is high, satisfies simultaneously the technological requirement after optimizing, for effect has been brought into play in the raising of production efficiency.
Description of drawings
Fig. 1 is the structural representation of present embodiment.
Fig. 2 is the structural representation of the round platform compact heap of present embodiment.
Fig. 3 is location briquette structure and the process figure after feed path is optimized.
Fig. 4 is the partial enlarged drawing of circular portion among Fig. 3.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, present embodiment is implemented under take technical solution of the present invention as prerequisite, provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, contiguous block 1 is connected with anchor clamps 3 in the present embodiment, and round platform compact heap 2 and contiguous block 1 are connected with engine cylinder-body and are connected.
Described round platform compact heap 2 is quadrant platform structure, the round platform top half-angle α of this compact heap 2/number of degrees of 2 and the tool cutting edge angle κ of face milling cutters 5
rNumber of degrees sum be 90 °.
The bottom surface diameter D of described round platform compact heap 2 is the twice of the difference of optimizing after advancing path 6 arc section radius Rs and face milling cutters 5 radius of clean-up r, i.e. D=2 * (R-r); The upper bottom surface diameter d is the thickness h of bottom surface diameter D and round platform compact heap 2 and the tool cutting edge angle κ of face milling cutters 5
rLong-pending twice poor of cotangent value, i.e. d=D-2hcot κ
r
Described round platform compact heap 2 bottom surface round platforms and engine cylinder-body 4 processing end faces are affixed.
As shown in Figure 3, contiguous block 1 is by being installed on the anchor clamps 3, and compact heap 2 contacts with cylinder body 4 end faces.Face milling cutters 5 carry out milling according to 6 pairs of cylinder body 4 end faces of feed path after optimizing, when Tool in Milling during to briquetting position, location, because the tool cutting edge angle of cutter and the round platform top half-angle of compact heap 2 be complementary angle each other, cutter is along with circular arc path can be carried out milling around round platform, thereby can not bump, thereby guaranteed carrying out smoothly of milling.
As shown in Figure 4, cutter does not bump near the briquetting of circular table location, and can pass through smoothly according to the feed path 6 after optimizing.
Adopt round platform compact heap 2 structures, have following advantage: the compression area of compact heap 2 is large, thereby makes the intensity of compact heap 2 obtain enhancing, and is more accurate to the location of cylinder body 4; According to the feed path requirement after optimizing, when cutter at briquetting position, location through out-of-date, with location briquetting collision, thereby reach accurate location to cylinder body.
