1. Ok! @Kieran and @Rarst, here it is 🙂

   function stoppostedition_filter( $capauser, $capask, $param){
   
     global $wpdb;   
   
     $post = get_post( $param[2] );
   
     if( $post->post_status == 'publish' ){
   
         // Disable post edit only for authore role
         if( $capauser['author'] == 1 ){
   
           if( ( $param[0] == "edit_post") || ( $param[0] == "delete_post" ) ) {
   
             // How much time have passed since post publication
             $post_time_unix = strtotime( str_replace('-', ':', $post->post_date ) );
             $current_time_unix = time();
             $diff = $current_time_unix - $post_time_unix; 
             $hours_after_publication = floor( $diff / 60 / 60 );
   
             // If 24 hours have passed since the publication than remove capability to edit and delete post
             if( $hours_after_publication >= 24 ){
   
               foreach( (array) $capask as $capasuppr) {
   
                 if ( array_key_exists($capasuppr, $capauser) ) {
   
                   $capauser[$capasuppr] = 0;
   
                 }
               }
             }
           }
         }
     }
     return $capauser;
   }
   add_filter('user_has_cap', 'stoppostedition_filter', 100, 3 );

2. Nice, @Alexey. Here is a simplified version, that does not disallow Administrators from editing. This version is more in the style of WordPress core, as I took it from the example code on the WordPress user_has_cap filter codex page and modified it.

   function restrict_editing_published_posts( $allcaps, $cap, $args ) {
   
       // Bail out if we're not asking to edit a post ...
       if( 'edit_post' != $args[0]
         // ... or user is admin
         || !empty( $allcaps['manage_options'] )
         // ... or user already cannot edit the post
         || empty( $allcaps['edit_posts'] ) )
           return $allcaps;
   
       $post = get_post( $args[2] );
   
       // Bail out if the post isn't published:
       if( 'publish' != $post->post_status )
           return $allcaps;
   
       // If post is older than a day ...
       if( strtotime( $post->post_date ) < strtotime( '-1 day' ) ) {
           // ... then disallow editing.
           $allcaps[$cap[0]] = false;
       }
       return $allcaps;
   }
   add_filter( 'user_has_cap', 'restrict_editing_published_posts', 10, 3 );
