The utility model content
The utility model technical issues that need to address provide the vertical knife sharpener that a kind of alternative workman whets a knife, thereby reduce industrial accident, improve degree of safety.
For addressing the above problem, technical solution adopted in the utility model is: a kind of vertical knife sharpener, comprise frame, rack-mounted workbench and grinding and feeding mechanism, wherein workbench is connected with the round driving mechanism of workbench by the tooth bar of bottom surface, and end face is equipped with the fixing and grinding angle regulating device of cutter.
This novel grinding cooling device that also comprises, this device comprises the water pump that is connected with motor, connects the conduit and the cooling spray of water pump.
Described workbench comes and goes driving mechanism and comprises motor, the reducing gear that links to each other with motor, and the belt gear that links to each other with reducing gear is by the gear of belt gear driving.
Described grinding and feeding mechanism comprises grinding mechanism, feed mechanism and fixed mount, and wherein grinding mechanism comprises motor, is fixed on the abrasive wheel chuck on the motor shaft, and motor is fixed on the motor slide plate; Feed mechanism comprises handwheel, connects the leading screw of handwheel, and with the leading screw nut engaged, wherein the motor slide plate of nut and fixed electrical machinery links together; The motor slide plate is fixed in the chute of fixed mount.
Described cutter is fixing to comprise the cutter fixation clip with the grinding angle regulating device, adjusts the cutter of tool grinding angle and adjusts plate, rotary table top, and wherein the cutter fixation clip is fixed on cutter on the rotary table top, adjusts plate by cutter and adjusts the grinding angle.
Adopt the beneficial effect that technique scheme produced to be: this is novel by motor and transmission mechanism drive tooth bar back and forth movement, thereby makes workbench do the horizontal linear back and forth movement, need not personnel's manual operation; The emery wheel of grinding mechanism is by motor direct-drive, and feed mechanism and grinding mechanism are fixed together, and drives emery wheel by feed mechanism and moves up and down, thereby reach the purpose of processing; Cutter is fixed and the grinding angle regulating device is used for fixing and adjust the tool grinding angle, thereby can process the different angles cutter, and fixture is the clamping cutter firmly, and cutter can't be moved in process, has good security.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
As shown in Figure 1, this novel frame 25 that comprises is installed in workbench and grinding and feeding mechanism on the frame 25, and wherein workbench is connected with the round driving mechanism of workbench by the tooth bar of bottom surface, and end face is equipped with the fixing and grinding angle regulating device of cutter.
Wherein grinding and feeding mechanism is shown in Fig. 2 a, 2b, comprise grinding mechanism, feed mechanism and fixed mount, wherein grinding mechanism comprises motor 2, is fixed on the abrasive wheel chuck 3 on the motor shaft, abrasive wheel chuck 3 is used for fixing abrasive grinding wheel, motor 2 directly drives, grinding is carried out in rotation at a high speed, and motor 2 is fixed on the motor slide plate 10 simultaneously; Motor slide plate 10 is fixed in the chute of fixed mount, can slide up and down along chute.Feed mechanism comprises handwheel 1, connects the leading screw 8 of handwheel 1, and with leading screw 8 nut engaged 9, wherein nut 9 is fixed on the motor slide plate 10, rotates handwheel, and the leading screw rotation drives the nut motion, moves up and down the amount of feeding when changing grinding thereby drive grinding mechanism.
This novel workbench and be installed on the fixing and tool grinding angle regulating device of the cutter of workbench shown in Fig. 3 a, 3b, 3c, wherein, workbench underrun tooth bar connecting plate 11 is connected with tooth bar, workbench 11 carries out grinding by fulcrum 13, bearing 12 left and right sides back and forth movement in the track that is made of back protecting crust 16, side protecting crust 17.Fixing and the grinding angle regulating device of end face mounting cutter on the workbench, it comprises cutter fixation clip 23, adjust the cutter of tool grinding angle and adjust plate 22, rotary table top 24, wherein cutter fixation clip 23 is fixed on cutter on the rotary table top 24, adjusts plate 22 by cutter and adjusts the grinding angle.
Figure 4 shows that tool grinding angle adjustment schematic diagram, cutter is fixed on the rotary table top 24 by pressing plate 23, rotary table top 24 is connected with table top adjustable plate 20 by regulating bolt, regulate rotary table top 24 to needed angle, tighten the adjusting bolt then, rotary table top and table top adjustable plate 20 are fixed.
Originally novel also be furnished with the grinding cooling device in order to guarantee the normal grinding of workpiece, and this device comprises the water pump that is connected with motor, connects the conduit and the cooling spray of water pump.
This novel table top comes and goes driving mechanism and comprises motor, reducing gear, belt gear, the axle that connects belt gear, be installed in the gear (wheel and rack cooperation) on the axle, wherein reducing gear directly is connected with motor, and belt gear connects reducing gear by belt pulley, drives the gear that is connected on the axle by another belt pulley simultaneously.Certainly, this is this novel a kind of embodiment just, can also be other driving mechanism.Round for controlling, stroke adjustment seat 18 is installed on backplate, travel switch is installed above, change motor steering by circuit, thereby change the working table movement direction.
