Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
The edging head device of a kind of auto-feed of the present embodiment, as shown in figure 1, including grinding subassembly 1, feeder assembly 2 With fixed seat 4, the grinding subassembly 1 is arranged on the inside of fixed seat 4, and the feeder assembly 2 is arranged on the outside of fixed seat 4;
As shown in Fig. 2 the grinding subassembly 1 includes grinding motor 11, grinding head shaft 12, edging wheel 13, slip cap 14 and connected Acting flange disk 16, the grinding motor 11 is installed on one end and its output shaft of slip cap 14 by the mounting flange 16 Towards the other end of the slip cap 14, the pivot bush unit of slip cap 14 is in the fixed seat 4, and the one of the grinding head shaft 12 Connected in the end insertion slip cap 14 and with the output shaft of the grinding motor 11, the edging wheel 13 is arranged on the bistrique The other end of axle 12;
As shown in Figure 2 and Figure 3, the feeder assembly 2 includes feeding motor 21, turbine 22, worm screw 23 and adjusting screw rod 24, The feeding motor 21 is arranged on the top of the fixed seat 4, and one end of the adjusting screw rod 24 is installed on mounting flange 16, The worm screw 23 and the output shaft connection of the feeding motor 21, the turbine 22 and the engagement connection of the worm screw 23, it is described to adjust The other end set of section screw rod 24 inserts in the turbine 22;The feeding motor 21 drives the adjusting screw rod 24 to move axially, from And drive the slip cap 14 to move axially.
In the grinding subassembly 1, the grinding motor 11 drives the grinding head shaft 12 around own axes rotation, so that band Move the edging wheel 13 to rotate, realize the grinding to adobe.In the feeder assembly 2, the feeding motor 21 drives The worm screw 23 rotates, and drives the turbine 22 engaged with worm screw 23 to rotate, the screw thread and the turbine 22 of the adjusting screw rod 24 Inner hole thread be engaged, so as to drive the adjusting screw rod 24 to move axially.One end of the adjusting screw rod 24 passes through described Mounting flange 16 is fixedly connected with slip cap 14, so that drive endoporus of the slip cap 14 along the fixed seat 4 to slide, it is real The existing loss of edging wheel 13 auto-feed compensation.The edging head device of the auto-feed is by the feeder assembly 2, in edging wheel Drive the edging wheel 13 to forward extend out when 13 front end is worn and torn to realize that auto-feed is compensated, it is ensured that adobe after edging Size is consistent, improves the quality of product, and reduces the workload of operative employee.
Preferably, as shown in Figure 1, Figure 3, in addition to pneumatic clamping component 3, the pneumatic clamping component 3 includes compressing gas Cylinder 31, active joint 32 and elastic press 33, the compression cylinder 31 are installed on the outside of the fixed seat 15, and the pressure The piston rod of tight cylinder 31 is towards the slip cap 14;The active joint 32 is installed on the piston rod of the compression cylinder 31, The elastic press 33 is socketed on the active joint 32.
In use, the edging head device of the auto-feed is fixed on the crossbeam of conveyer belt, adobe along brick-entering direction from The side of edging wheel 13, is steadily moved to its opposite side.In 13 high speed rotary grinding adobe of edging wheel, adobe can be to edging wheel 13 1 reaction forces;This reaction force can be delivered on slip cap 14, and slip cap 14 can be pressed on to the endoporus of fixed seat 4 On wall;When edging wheel 13 is not ground adobe, this reaction force disappears, slip cap 14 and the endoporus side wall point of fixed seat 4 From so as to gap occur;When 13 interrupted grinding adobe of edging wheel, slip cap 14 is constantly sent out with the endoporus side wall of fixed seat 4 It is raw to compress and separate, vibrations are formed, ground effect are influenceed, and easily cause the bore wear of fixed seat 4.
Therefore, the pneumatic clamping component 3 is set, and the piston rod of the compression cylinder 31 stretches out when in use, so that band Move the elastic press 33 on the active joint 32 and compress the side of the slip cap 14 so that the opposite side of slip cap 14 with The endoporus side wall of fixed seat 4 is adjacent to, so as to will not produce vibrations when being ground adobe, it is ensured that ground effect, extends described slide Set 14 and the service life of fixed seat 4.The elastic press 33 is flexible and flexibility, is more pasted with slip cap 14 during compression Close, and flexible contact can prevent from causing the slip cap 14 during compression abrasion.
Preferably, as shown in figure 1, the compression cylinder 31 is installed on the brick-entering direction A of the fixed seat 4 side.By Towards brick output direction (brick-entering direction A opposite direction) when reaction force of the adobe to edging wheel 13, therefore can be by slip cap 14 are pressed on the inner hole wall in brick output direction of fixed seat 4.The compression cylinder 31 is installed on the brick-entering direction of the fixed seat 4 A side, so that slip cap 14 is pressed on the inner hole wall in brick output direction of fixed seat 4, it is to avoid the compression cylinder 31 is made The force direction for acting on edging wheel 13 used in the power of slip cap 14 and adobe is mutually formed on the contrary to be contended with, and better profits from adobe to mill The reaction force of cincture 13.
Preferably, the active joint 32 is removably installed in the piston rod of the compression cylinder 31, the elasticity pressure Block 33 is removably socketed on the active joint 32.The active joint 32 and the elastic press 33 are consumable accessory, if Demountable structure is put to change.
Preferably, as shown in Fig. 2 the grinding subassembly 1 also includes dust cover 17, the outside at the two ends of the slip cap 14 The dust cover 17 is equipped with, the two ends of the slip cap 14 are connected by the dust cover 17 and the fixed seat 15;Institute Dust cover 17 is stated for retractable and flexible material.
Because the relatively described fixed seat 15 of the slip cap 14 is moved axially, easily by things such as chip dust during grinding adobe Matter is splashed in the gap between the slip cap 14 and the fixed seat 15, therefore sets the dust cover 17, prevents the cunning There is the materials such as chip dust and influence to move effect or occur stuck in the gap between dynamic set 14 and the fixed seat 15.It is described Dust cover 17 is retractable and flexible material, in order to which the dust cover 17 stretches with the movement of the slip cap 14.
Preferably, as shown in Fig. 2 the grinding subassembly 1 also includes shaft coupling 18 and elastic connection sleeve 19, the grinding head shaft 12 one end is connected by the output shaft of the shaft coupling 18 and the grinding motor 11;The elastic connection sleeve 19 is socketed on institute State the outside of shaft coupling 18.The elastic connection sleeve 19 is made using high polymer material, can with transmission moment of torsion, vibration-absorbing function Make the power of grinding motor 11 is steady effectively to pass to grinding head shaft 12 by shaft coupling 18, drive the steady operation of edging wheel 13, The impact brought during 13 intermittent grinding adobe of edging wheel to grinding motor 11 can also be eliminated simultaneously, protected grinding motor 11, prolonged The service life of long grinding motor 11.
Preferably, as shown in figure 3, the feeder assembly 2 also includes reductor 25, the worm screw 23 passes through the reductor 25 and it is described feeding motor 21 output shaft connection.25 pairs of the reductor feeding motor 21 plays reduction rotating speed and increase The effect of torque, making the rotating speed of the worm screw 23 reduces, and in order to which the turbine 22 drives adjusting screw rod 24 slowly mobile, realizes Fine setting to the amount of feeding of edging wheel 13.
The technical principle of the present invention is described above in association with specific embodiment.These descriptions are intended merely to explain the present invention's Principle, and limiting the scope of the invention can not be construed in any way.Based on explanation herein, the technology of this area Personnel, which would not require any inventive effort, can associate other embodiments of the present invention, and these modes are fallen within Within protection scope of the present invention.
