Overview of Work Locating Components

This document provides detailed technical specifications, usage instructions, and product data for various types of work locators, locating pins, and related components used in precision mechanical setups.

1. Spring-Loaded Work Locators (CP710 Series)

• Types: Standard (CP710-A) and Accurate (CP710-B).
• Material: Body made of quenched and tempered steel (S45C or SK95) with black oxide finish.
• Locating Pins: Tapered pins designed to eliminate clearance between pin and locating hole, ensuring precise vertical and horizontal positioning.
• Dimensions & Parameters: Various part numbers correspond to different through-hole diameters (φ3.8 to φ10.2 mm), spring constants (1.3 to 9.9 N/mm), support capacities (up to 100 N), and weights (up to 170 g).
• Usage Notes: The tapered pin is pressed down to locate the workpiece securely. Chamfering of through holes up to 1x1 mm is allowed. Use with supports 2 mm higher than the workpiece to ensure proper clearance.

2. Work Locators CP700 Series

• Material: Body made of SCM440 steel, handle of SCM435 steel with ABS resin ball knob, black oxide finish.
• Features: Locating pin projects only after the workpiece is set on supports, preventing galling and damage during loading/unloading.
• Dimensions: Various sizes with locating pin diameters from 12 to 14 mm, weights ranging from 0.42 to 1.04 kg, and allowable operating loads up to 300 N.
• Usage: Rough locating with guides followed by pin projection for precise centering.

3. Extendable Work Locators CP701 Series

• Material: Body and piston crank shaft made of quenched and tempered steel (S45C), black oxide finish.
• Features: Adjustable handle position (clockwise or counterclockwise), piston locks in projected or retracted position until handle is operated again.
• Applications: Suitable for heavy steel or cast iron workpieces, no tools required for operation, customizable with extension shafts and shaft holders for limited space environments.
• Dimensions & Load: Pin diameters from 12 to 16 mm, weights up to 1.31 kg, allowable operating loads up to 300 N.

4. Locating Screws (BJ700 Series)

• Material: SCM435 steel, quenched and tempered, black oxide finish, precision ground.
• Sizes: Various thread sizes (M12×1.75, M16×2) and dimensions to fit different locating requirements.
• Usage: Used to secure components with multiple locating screw holes.

5. Locating Pins

• Round Locating Pins (BJ720 Series): Quenched and tempered SKS93 equivalent steel, precision ground, Rc 55-60 hardness.
• Diamond Locating Pins (BJ722 and BJ723 Series): Similar material and hardness as round pins, designed for precise locating with diamond-shaped heads.
• Features: Use of pin extractors recommended for removal, various sizes and weights provided for different applications.

6. Flat Keys (BJ712 Series)

• Material: S45C steel, quenched and tempered (Rc 39-45), black oxide finish.
• Application: Used with D-socket-head cap screws for machine tables and fixture plates.
• Dimensions: Various sizes with precision ground surfaces.

Critical Usage Recommendations and Best Practices

• When clamping, hold down the workpiece manually to prevent lift caused by spring force.
• Use tapered pins to eliminate clearance and ensure secure locating.
• For accurate positioning, use the Accurate Type locators that allow vertical and horizontal alignment.
• Locating pins should be pressed down only after the workpiece is roughly positioned to avoid galling and damage.
• Adjustable handles on extendable locators allow flexible operation in confined spaces.
• Chamfer through holes up to 1x1 mm to facilitate pin insertion.
• Use supports 2 mm higher than the workpiece to maintain proper clearance.
