Fixtureworks Expands Range of Workholding Clamps

Fixtureworks, a North American manufacturer and supplier of clamps, fixturing accessories, machine tool components, rollers and bumpers, has expanded its array of manual-style fixture clamps. With over 80 varieties of clamps, including, swing, thrust, side toggle, pneumatic, form holding, pull and strap, these clamps are adaptable to different industrial applications and systems. They are designed to provide quick, secure and precise workpiece workholding and are manufactured to the highest quality specifications.

The product mix includes many clamp accessories such as mounting brackets, adaptors, bars and caps. In both mini and heavy-duty styles, the various clamp configurations provide clamping forces from as little as 2 lb. on a toggle switch to as much as 9,000 lb. on a side clamp and come with a variety of handle materials from steel to plastic.

Swing clamps provide an expansive range of arm travel and length of arm options, making these clamps a versatile choice for a variety of clamping, fixturing and workholding application, and especially useful for highly repetitive clamping jobs. The swing clamps are said to offer ease of operation — the rotation of an ergonomic handle simultaneously swings the clamp arm out and over the workpiece and into the clamping position, then a final pressure on the arm draws the arm down and applies direct downward force on the part.

Precision thrust clamps can clamp at the same position by precise projection of clamping bars. The spring-loaded clamp provides constant clamping force. The handle features a click alert to indicate complete clamping.

Side clamps use smaller clamping space, which enables greater machine clearance. Mounting screws can be under the workpiece, minimizing clamping space. Tightening the ball screw forces the clamp forward and downward. The hex socket setscrew works to prevent the clamp from sliding back when clamping. They are made from alloy steel with a black-oxide finish.

Toggle clamps offer a high-quality, durable alternative to other clamps. The non-slip ergonomic handle allows for easy and comfortable use with smooth edges to prevent snagging. These clamps feature high-quality bushings that won’t score and are designed to withstand over 300,000 cycles. Their attractive appearance provides a high-quality look to finished products.

Pneumatic pull clamps provide very quick and secure fastening for repetitive machining operations. The clamp base receives a customized pin based on the thickness of the part you are clamping. When air pressure is applied, the pin is pulled downward and secured into position by a wedge mechanism, which provides a high clamping force.

Form-holding clamps are designed to clamp onto the circumference of oddly shaped workpieces. Expanding ID clamps are designed to clamp onto the inside of workpieces, ideal for parts with varying inside diameters. These part holding clamps come in round or square wedge styles and in mini or standard sizes.

The pull clamps are designed to provide high-accuracy workpiece locating, utilizing precision ground clamping pins that are used in conjunction with the fixture-mounted clamp mechanisms.  The clamp devices apply downward pressure on the pins via a quarter turn of the clamp’s handle that actuates a spiral cam (ball and groove) design. This, in turn, applies downward pressure on the workpiece and secures it in position. 

The versatile strap clamp assembly provides high clamping force. Used to hold down dies, fixtures and workpieces on a wide variety of machines. The long mounting slot offers a wide range of clamp movement and positioning. The strap end is tapped for support.
