Tools 1

[nithink]

We are planning to create a CAD database of standard tools[Wrenches,sockets, adapters etc.].

Have couple of questions.

Is ASME B107 stanadad followed by all the tool suppliers like Snap on,Norbar etc?

Can we get the External dimensions [such as OD of handle] for Impact wrenches,torque wrenches etc?


don't have access to ASME B107 documents.

You also may want to post this on the Siemens: UG/NX forum since someone there may already have at least a partial library that they may be willing to share with you or may have found a source either for the actual models or for the specs that you're looking for.

We sell tools and we have over 20,000 different tools on our web site at

http://www.carbideprocessors.com

Our best estimate is that there are millions of different tools in the world at any one time and the number is growing. As an example, the electronics industry opened up a whole new tool field field for anti-static tools.

Screwdrivers sound easy except that there are a couple dozen common screws plus security screws. A security screw takes a special screwdriver. There are companies that specialize in developing new security screws, each of which requires a new screwdriver.

I suspect that nithink's real issue, since he specifically mentioned wrenches and sockets, is that the 3D size of these need to be taken into consideration when designing machinery which has to be both assembled and disassembled for servicing so that they can reach the fasteners and that there is sufficient clearance for them to actually be used properly.

But to help the cause along, I've attached a couple of files, one for sockets and the other is a combination box end/open end wrench (these are NX family-table parts but I can't vouch for them complying to any particular standard since they were 'gifted' to me several years ago).

I've found that the wrench clearances suggested in my (very old) copy of Machinery's Handbook are conservative, i.e. they allow room for thick-walled sockets and wrenches produced before WW2. Modern tools (except impact types) are much thinner, and differ considerably from one manufacturer to another.

I.e., if you are going to make your assemblies so tight that only your standard CAD wrenches will fit, then it may be necessary to pick a single tool manufacturer, make your CAD models look like their tools, supply those specific tools to your service people, and make those specific tools available for sale to your customers too.

Make your CAD wrenches oversized, comprising the union of all the common name brand tools of that type.

Call the vendor and ask??

I checked the Part Family files that I provided in my earlier post and it appears that whoever created them was basing them on 'Snap-On' tools. Note that they only cover Imperial, or what in the tool world would be called SAE sizes, (i.e. Inch units).

John, thanks a lot for the files we can use them as template.This is the precise thing what we intended to do [Part family].I will re post this thread in NX forum as you mentioned.
We use lot of tools from Snap-on.

MikeHalloran,making wrenches oversize in CAD is bit tricky as managers here wants this project goes per process . As for Machinery handbook is concerned one of the pictures they shown is where wrench is used directly,but if we use sockets we gain more clearance[two bolts can be used close to each other]

Miketheengineer Its not easy to get the catalogues with all the outside dimensions required to create a UG model [example - Impact wrenches]

tomwalz As John said i mainly interested in regularly used standrad tools used in my field.

I missed the "in your field" and the mention of what your field is.

As usual, my point seems to have been better made by some of the other posts.

What Mike said. Last time I did the excersize, I found that the o.d. of a typical socket varied in size roughly as (smallest od to largest): Snap-On < Craftsman < Cheap chrome-plated sockets from the hardware store < Impact sockets.

 

[nithink]

btrueblood,how much variation?

I can't believe that someone is actually designing a machine so it can be disassembled using standard tools. Most of the machines I work on require custom tools for at least some of the fasteners. We regularly have to modify tools (turn down the OD of a socket) or make custom tools from scratch. Split line fasteners for large turbo-machinery are notorious for this. Thank you for thinking of the poor maintenance guy.

Perhaps the 'special tools' could be by-design to prevent any 'driveway mechanics' from performing repair jobs which should only be done by trained professionals with the proper tools. Sort of like the use of 'security' screws when a manufacturer wishes to prevent access to the internals of some device yet still allow for maintenance and repair by qualified technicians.

We also use many custom tools made by a supplier fro us.
The 'Machine' we build is big and have option to use many standard tools, so requires clearance checks during design stage.
