Show Only Grouped Products in Woocommerce

Question

In Woocommerce, Due to an inventory sku issue with clothing size, we have two different products for ultimately the same product. Let's call it a blue shirt, but it is 2 different products in our store due to an ordering decision. I've created a grouped product to handle the display of this.
However I can't seem to hide the linked products from my shop. When I use the WC_Product_query class and the get_products function, it doesn't seem to return all 46 products that are being queried. I'm wondering what exactly, I'm doing wrong and/or if there is a better solution.

Placed the following in my functions.php child theme:

add_action( 'woocommerce_product_query', 'only_grouped_products_query' );
function only_grouped_products_query( $q ) {
    $query = new WC_Product_Query(array($q));   

    $products = $query->get_products();

    $linked_array = array();
    $i = 0;
    foreach($products as $product){     
        $i++;
        /*
        echo $product->get_name() .' - ' . $product->product_type .'<br>';
        $is_grouped = $product->product_type;
        if ( $is_grouped == 'grouped' )
        {
            // echo $product->get_name() .' - ' . $product->product_type;
            $get_child_id = $product->get_children();
            if (is_array($get_child_id)){
                foreach($get_child_id as $child_id){
                    $linked_array[] = $child_id;
                }
            } else {
                $linked_array[] = $get_child_id;
            }
        }
        */
    }
    echo $i;
    // $q->set( 'post__not_in', $linked_array );
}

The above code snippet does work, but it doesn't pull in all 46 results that the query is showing when I dump the original $query variable. $i only returns 10 results.

Your question body explanations are not so clear… So I base this answer on your question title.

As the product type in Woocommerce is handled by product_type custom taxonomy, you need to use a Tax query instead.

The following code will display only grouped product types on all Woocommerce archive pages:

add_filter( 'woocommerce_product_query_tax_query', 'only_grouped_products', 20, 1 );
function only_grouped_products( $tax_query ){
    $tax_query[] = array(
        'taxonomy'  => 'product_type',
        'field'     => 'name',
        'terms'     => array('grouped'),
    );
    return $tax_query;
}

Code goes in function.php file of your active child theme (active theme). Tested and works.

Woocommerce default product types (and other custom product types)

So you can handle any product type:

For Simple products you will use: 'terms' => array('simple'),
For Variable products you will use: 'terms' => array('variable'),
For Grouped products you will use: 'terms' => array('grouped'),
For External products you will use: 'terms' => array('external'),

And also all these custom product types (from known 3rd party plugins):

For Composite products you will use: 'terms' => array('composite'),
For Simple Subscriptions products you will use: 'terms' => array('subscriptions'),
For Variable Subscription products you will use: 'terms' => array('Variable Subscription'),
For Booking products you will use: 'terms' => array('booking'),

You can combine multiple product types too like for example simple and grouped products types only:
You will use: 'terms' => array('simple', 'grouped'), … and so on.
