Abstract:
A tension testing kit for testing the holding force of a drawbar assembly on a HSK spindle, comprising:a. a grip-housing capable of connecting to the HSK spindle, said grip-housing having a longitudinally aligned threaded bore and opposite distal and proximal ends, said distal end including a protruding lip that can be selectively engaged by the drawbar assembly on the HSK spindle to hold said grip-housing on the HSK spindle; b. a guide piece longitudinally aligned over said grip-housing, said guide piece including an internal cavity that receives said grip-housing, said guide piece including a bore longitudinally aligned with said threaded bore on said grip-housing, said guide piece including an upper support surface; c. an upper frame member disposed over said guide piece; d. a transfer rod used to threadingly connect said grip-housing to said upper frame member; e. a clevis disposed between said upper frame member and extending to said support surface on said guide piece; f. a force-measuring means disposed between said clevis and said upper frame member used to measure the amount of pulling force exerted on said grip-housing by the drawbar assembly.
