The protrusion of the left shifting block is matched with the first groove, the protrusion of the right shifting block is matched with the second groove, the lower surface of the pressing block is connected with the gasket and the clamp spring, the screw is inserted into the middle hole, the gasket and the clamp spring of the pressing block, the other end of the screw is connected with the middle screw hole of the tool body, the left inclined plane of the pressing block is in contact with the inclined plane of the left shifting block in an inosculating mode, the right inclined plane of the pressing block is in contact with the inclined plane of the right shifting block in an inosculating mode, the protrusion of the left shifting block is in contact with the first groove. The screw is screwed in downwards, the pressing block moves downwards, the pressing block enables the right shifting block and the left shifting block to move outwards (slide towards two sides) downwards, the right shifting block abuts against and fixes the second knife handle, and the left shifting block abuts against and fixes the first knife handle. The processing method can be used for simultaneously processing in two vertical type processing centers, the processing time is shortened by half while the product quality is ensured, the production efficiency is improved, and the delivery date is ensured.
Description
Technical Field
The utility model relates to a handle of a knife shifting block groove processingequipment belongs to mechanical technical field.
Background
For the tool shanks with more processing parts, the precision requirement is high, the procedure is complex, the common vertical processing center cannot process the tool shanks, and the turning and milling combined processing is used at present.
The turning and milling composite processing time is long, the quantity of the cutter handles produced and processed every day is small during batch processing, the efficiency is low, and the subsequent processing arrangement and delivery date are influenced.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a processing device for a knife handle shifting block groove.
A tool body is provided with a left cavity, a right cavity and a middle screw hole, the left cavity is placed into a first tool handle, the right cavity is placed into a second tool handle, the first tool handle is provided with a first groove, the second tool handle is provided with a second groove, a pressing block is provided with a left inclined surface and a right inclined surface, one end of a right shifting block is provided with an inclined surface, the other end of the right shifting block is provided with a bulge, one end of the left shifting block is provided with an inclined surface, the other end of the left shifting block is provided with a bulge, the left inclined surface of the pressing block is matched with the inclined surface angle of the left shifting block, the right inclined surface of the pressing block is matched with the inclined surface of the right shifting block, the bulge of the left shifting block is matched with the first groove, the bulge of the right shifting block is matched with the second groove, a gasket and a clamp spring are connected to the lower surface of the pressing block, a screw is inserted into the middle hole, the gasket and the clamp spring of the pressing block, the other end of, the protrusion of the left shifting block is in contact connection with the first groove, and the protrusion of the right inclined plane is in contact connection with the second groove.
The utility model has the advantages that with this type of handle of a knife from turning and milling combined machining center to two ordinary vertical machining center processing. A vertical machining center machines a shifting fast opening and a balance groove on the excircle, and the process can be finished by one-time clamping; the other vertical machining center uses the tool clamp. Because the size requirement of the end face key groove of the knife handle is strict and has a requirement on the form and position tolerance of the excircle shifting block port, the tool can be used for positioning the machined excircle shifting block port, the end face key grooves of 2 knife handles can be machined simultaneously, the size is ensured during machining, and the requirement on symmetry of the excircle shifting block port is also ensured. The tool can be suitable for machining most tool handles. The processing method can be used for simultaneously processing in two vertical type processing centers, the processing time is shortened by half while the product quality is ensured, the production efficiency is improved, and the delivery date is ensured.
