The task for the control work number 2
In engineering drawing
Verification work number 2 consists of 4 tasks (5 sheets).
All tasks are performed on sheets of A3. each sheet is made in accordance with GOST 2.301-68. on each sheet drawn inner frame and title block is executed in the form 1 (GOST 2.104-68) s.156-157 Figure 6.5; 6.6 [1] 19 [2].
Column (1) is written the name of the parts (for drawings of parts).
All entries in the main signatures are performed in GOST 2.304-81.
Quest 2-1 (sheet 2-1) to perform a sketch detail. Setting is performed on a sheet of paper into the cell either on graph paper A3. The sheet is made in accordance with GOST 2.301-68. Details thumbnail contains the same information as the details of the drawing, only done by hand (without the use of drawing tools) and for the eyes. The item can be increased or decreased in any scale, if necessary. Assigning sketch - production details once, to work on the design drawing. The number and type of images selected depending on design details.
Once all the images are put the actual dimensions of the items, which should measure the item.
Detail sketch for students selected independently. The item type "Val", "Widget" has to have a cylindrical, stepped form. There may be faceted surface to be thread (internal or external).
Example of sketching and playing c.214ris.10.1,10.2 s.217,218 Figure 10.3; 10.5 s.272-277 ris.10.20-10.21 [1] ris.357 p.283 [2].
Setting 2-2 (2-2 leaf). Run a workpiece drawing. Detail to perform the drawing to pick their own. The part should be of the "housing", "flange", etc. It should have an internal cavity opening thread. Plans to perform at A3. Example of a drawing in the c / 287-288 ris.10.24, b. [1]
Fig. 357 p.283 [2].
Target 2-3 (2-3 leaf) drawing a threaded connection.
Run, drawing the connection of two parts with the bolt. See sample. Ris.10.18 on p.266 a, b, c; s.206-208 Figure 9.4 [1] str.241 ris.311 [2]. In this figure, performed two types of images bolting left - constructive - as it looks really left - uproschennoe- as it is drawn on the assembly drawings. You must perform the two images on a sheet of A3.
the dimensions of the parts taken arbitrarily. The size of the bolt choose from table 25 mtr.231 [1] depending on the diameter of the thread of the bolt d. Variants of the bolt thread diameters d have the top row of the table 10.3, s.262,263 or Table 25 str.231 [2]. According to the selected diameter of the bolt thread nuts find the dimensions of the table 26 str.233 [1].
The size of the table to pick up the puck 31 str.238 [1]. Plans to perform at a scale 1: 1. the thickness of the parts to take not less than 30mm. Below pictures sign full designation of bolts, nuts and washers specifying font №5 GOST GOST 2.304-81.s.266 ris.10.18 [1] (sm.str.226 [2])
Setting 2-4 (2-4 leaf, sheet 2-5). Performing assembly it is drawing (sheet 2-4). Drawing up specifications (list 2-5).
Sheets 2-4 - Assembly drawing of the product. To make the product assembly drawing is selected by students themselves. Recommended item "valve", consisting of 5-8 parts connected to each other.
An assembly drawing is performed on the product A3 in two forms with a simple full cut in accordance with the standards ESKD. P.228 Fig. 10.10, p.226 [1] (str.284 [2]).
On the assembly drawing tabulated only the dimensions of the entire product. Numerals stamped parts according to specification.
Sheets 2-5 - Spetsifikatsiyac. Ris.10.10 228 (below) [1] (str.285 [2]) is performed on a separate sheet of A4 in accordance with GOST 2.108-68. The main inscription in the specification of the first sheet is carried out in form 2 (height = 40 mm.), The next sheet in form 2a (height = 15mm. (Str.289 ris.359 [2]). The specification includes all details of standard products included a subassembly.
