Description

Technical Field

[0001] The invention relates to the technical field of machine tool processing, in particular to a special machine tool for broaching a chuck jaw stop. Background Art

[0002] During the machining process, traditional broaching machines cannot process the workpiece in one go due to its large diameter. Instead, repeated machining is required to achieve the optimal machining state. During repeated machining, manual workpiece clamping and tool replacement are usually required. This method is not only inefficient, but also prone to operational errors, affecting machining accuracy and product quality consistency. Especially when processing a variety of different materials or performing multiple machining operations with different specifications, manual adjustment and tool replacement become key factors restricting production efficiency.

[0003] In addition, traditional broaching machines often lack adjustment functions and are difficult to adapt to diverse processing needs. For example, when processing the outer surfaces of different metal materials, it is impossible to automatically clamp the workpiece and cannot meet the clamping processing of workpieces of different diameters. The clamping components need to be replaced or adjusted, and these adjustments usually depend on the operator's experience and technical level, which increases the uncertainty and complexity of production.

[0004] Therefore, the present invention provides a special machine tool for broaching the stop of a chuck jaw to solve the above problems. Summary of the Invention

At this time, the driving gear 402 drives the linkage shaft 403 to rotate, so that the eccentric wheel 404 hits the sealing slide 406, so that the sealing The sealing slide 406 squeezes the coolant on its upper part, so that the coolant is sprayed out from the spray pipe 409 to achieve cooling of the workpiece during processing; through the setting of the linkage shaft 403, the device can automatically start the coolant when the device is started, and it will only start automatically when the workpiece is processed, which can avoid the waste of coolant. At the same time, the sealing slide 406 of the device squeezes the coolant to achieve the pressurization function, and the lower pressure plate 407 can make its bottom abut against the outer surface of the coolant, which is convenient for the pressurization function of the sealing slide 406.
