Description

A turret type four chuck knife grinder

technical field

The invention belongs to the field of mechanical engineering, and more specifically relates to a turret-type four-clamp knife grinder.

Background technique

In the machinery manufacturing industry, machining is inseparable from a variety of cutting tools. There are many types of cutting tools, such as turning tools, drilling tools, end mills, end mills and planers. The tool will gradually become blunt during the machining process. If the blunted tool cannot be replaced or sharpened in time, not only the accuracy and surface quality of the workpiece will be affected, but also the tool will be easily damaged and the tool will be scrapped. A sharpener is a device used to sharpen a tool that has been blunted during machining to restore its processing characteristics. Since the cost of the tool occupies an important position in the machining cost, the sharpening of the tool is very important. The current universal knife grinder can process different types of tools such as computer engraving knives, milling cutters, and turning tools. Different fixtures need to be replaced during sharpening, time-consuming and labor-intensive disassembly and installation, complicated fixture structure, increased cost, and reduced processing efficiency.

Contents of the invention

The present invention aims to design a turret-type four-clamp knife sharpener that can eliminate the above-mentioned shortcomings, has a relatively simple structure, avoids the need to replace different fixtures when sharpening different tools, and has high work efficiency and excellent economic performance.

In order to achieve the above object, the present invention provides the following improvements: the power mechanism is mainly composed of a motor, a V-belt, a V-belt, a grinding wheel shaft, a grinding wheel, a bearing, etc., and the motor passes through the V-belt pulley, the V-belt and the grinding wheel shaft. Power, the grinding wheel is placed on the grinding wheel shaft, fastened on the grinding wheel shaft through threaded connection, and rotates with the grinding wheel shaft; the overall tool holder is mainly composed of a turntable, a turntable seat, a locking handle, and a tool holder. The slide shaft is connected with the whole of the sharpener, wherein the turntable seat A is connected with the slide shaft, the turntable seat B is connected with the turntable seat A through the screw shaft, the turntable is connected with the turntable seat B through the turntable shaft, and the knife clamping device is connected by screws, The turret shaft is connected with the turntable. The tool clamping device is composed of three boxes. The clamping between the boxes is realized by the tightening rod, the spring and other mechanisms to realize the clamping of the three boxes. The body is connected, and with the rotation of the upper box, the processing position of different types of tools can be changed.

The effective gain produced by the present invention is: when sharpening different tools, the upper box can be rotated around the turret axis through the turret-type tool holder, so that the corresponding tool holder can be transferred to the processing position, which is convenient and quick without disassembly Corresponding to the installation of the fixture, the turret-type tool clamping device has a simple structure, which effectively improves the processing efficiency.

detailed description

The present invention will be described in detail below in conjunction with the accompanying drawings: as shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of turret-type four chuck sharpening machine, main structure comprises: 1 fine-tuning mechanism, 2 motors, 3 Grinder casing, 4 Grinding wheel shaft sleeve, 5 Deep groove ball bearing, 6 Grinding wheel shaft, 7 Grinding wheel cover, 8 Grinding wheel, 9 Turntable, 10 Turntable seat B, 11 Turntable seat A, 12 Sliding shaft, 13 micro Feed mechanism, 14 locking seat, 15V belt, 16V pulley, 17 upper box, 18 middle box, 19 lower box, 20 lock handle a, 21 lock handle b, 22 lock handle c, 23 dial shaft , 24 round handle fixtures, 25 tapered handle fixtures, 26 turning tool fixtures, 27 carving knife fixtures, 28 tightening rods, 29 turning handles. When the universal knife grinder starts to work, the 2 motor drives the 16V pulley to rotate through the 15V type belt, thereby driving the 6 grinding wheel shaft to rotate, and the 8 grinding wheel is fixed on the 6 grinding wheel shaft and rotates with it.
