Examples
In this embodiment, there is provided a polishing apparatus for an engine cylinder head of an automobile, comprising a conveying mechanism 100 for moving in a first direction with the engine cylinder head of the automobile, and a polishing mechanism disposed above the conveying mechanism 100 for polishing an upper surface of the engine cylinder head of the automobile when passing therethrough.
In one or more embodiments, as shown in fig. 1, the conveying mechanism 100 is a conveyor of the prior art, preferably, the conveying mechanism 100 is a roller conveyor. The roller conveyor is horizontally arranged, and comprises a bracket 110, a transmission roller 120 and a driving device (not shown), wherein the two ends of the conveying direction of the roller conveyor are respectively a feeding end 130 and a discharging end 140. When the automobile engine cylinder cover needs to be polished, the automobile engine cylinder cover is placed on the roller conveyor at the feeding end 130 conveyed by the roller conveyor, the driving roller 120 of the automobile engine cylinder cover is driven to rotate by the driving device of the roller conveyor, so that the automobile engine cylinder cover moves from the feeding end 130 of the conveying mechanism to the discharging end 140 of the automobile engine cylinder cover, and when the automobile engine cylinder cover passes through the polishing mechanism, the polishing can finish the polishing treatment on the upper surface of the automobile engine cylinder cover.
Further, in one or more embodiments, the loading end 130 and the unloading end 140 are provided with a loading mechanism (not shown) and a unloading mechanism (not shown), respectively. The feeding mechanism and the discharging mechanism can respectively and continuously place the automobile engine cylinder cover on the roller conveyor and take down the automobile engine cylinder cover from the roller conveyor, so that the automobile engine cylinder cover can be polished in a pipelining manner, and the polishing efficiency of the automobile engine cylinder cover is greatly improved. In one or more embodiments, the loading mechanism and the unloading mechanism may be manipulators in the prior art, and of course, not limited thereto, and the loading mechanism and the unloading mechanism may be other mechanisms capable of completing loading and unloading operations on the cylinder head of the automobile engine.
As shown in fig. 2 and 3, the polishing mechanism includes a polishing roller 200, a first driving mechanism 300, and a second driving mechanism 400; the polishing roller 200 is parallel to the upper surface of the cylinder cover of the automobile engine, the axial direction of the polishing roller 200 is perpendicular to the first direction, a polishing layer is arranged on the outer peripheral surface of the polishing roller 200, and the axial length of the polishing layer is greater than the length of the upper surface of the cylinder cover of the automobile engine in the direction perpendicular to the first direction; the first driving mechanism 300 is used for driving the polishing roller 200 to move in a second direction so as to keep a set distance between the polishing roller 200 and the upper surface of the cylinder cover of the automobile engine, and the second direction is perpendicular to the first direction; the second driving mechanism 400 includes a shaft sleeve 410, a driving motor 420, and a damping assembly 430, where the shaft sleeve 410 is rotationally connected with one end of the polishing roller 200, the driving motor 420 is used to drive the shaft sleeve 410 to rotate circumferentially, the damping assembly 430 is disposed between the shaft sleeve 410 and the polishing roller 200, and can provide damping when the polishing roller 200 rotates relative to the shaft sleeve 410, and the damping assembly 430 further includes a detecting component, where the detecting component can monitor the relative rotation of the polishing roller 200 and the shaft sleeve 410 during polishing operation, and the speed of the conveying mechanism 100 for conveying the cylinder cover of the automobile engine gradually decreases as the relative rotation degree of the polishing roller 200 and the shaft sleeve 410 increases gradually.
Before polishing, the first driving mechanism 300 can drive the polishing roller 200 to move along the second direction, so that a set distance is kept between the polishing roller 200 and the upper surface of the automobile engine cylinder cover, the set distance is adaptively set by a worker according to polishing requirements, during polishing, the driving motor 420 drives the shaft sleeve 410 to circumferentially rotate, the circumferential rotation of the shaft sleeve 410 can drive the polishing roller 200 to rotate through the damping component 430, when the automobile engine cylinder cover is conveyed to the lower part of the polishing roller 200 by the roller conveyor, the polishing layer of the polishing roller 200 can be contacted with the upper surface of the automobile engine cylinder cover and polished through the polishing layer when the polishing roller 200 rotates, in the process, friction force is generated between the polishing layer and the upper surface of the automobile engine cylinder cover and acts on the polishing roller 200 through the polishing layer, so that the polishing roller 200 transmits acting force to the damping component 430 and rotates relative to the shaft sleeve 410, in this process, the angle detecting means can monitor the angle of relative rotation between the polishing roller 200 and the shaft sleeve 410, when the angle detecting means monitors the angle of relative rotation to increase, it is indicated that the roughness of the contact portion between the polishing roller 200 and the upper surface of the engine cylinder cover of the automobile increases, the friction force is larger, at this time, the conveying mechanism 100 can reduce the speed of conveying the engine cylinder cover of the automobile, ensure that the polishing roller 200 can sufficiently polish the rough portion of the cylinder cover surface, and when the angle detecting means monitors the angle of relative rotation to decrease, the contact portion between the polishing roller 200 and the upper surface of the engine cylinder cover of the automobile is smoother, the friction force is smaller, at this time, the conveying mechanism 100 can increase the speed of conveying the engine cylinder cover of the automobile, so that the device can automatically control the feeding amount according to the roughness of the upper surface of the engine cylinder cover of the automobile, thereby sufficiently polishing the head surface.
In the technical scheme, the polishing roller 200 is adopted to carry out polishing treatment, compared with the polishing disc adopted to carry out polishing treatment in the prior art, the polishing roller 200 is in linear contact with the upper surface of the cylinder cover of the automobile engine in the technical scheme, and the polishing disc is in surface contact with the upper surface of the cylinder cover of the automobile engine. As shown in fig. 9 and 10, a region of greater roughness is at a, and a smoother portion is at B. When the polishing pad moves from a to B, since the feed amount is controlled according to the roughness, i.e., according to the magnitude of the frictional force, the frictional force formula f=μ×fn, i.e., the magnitude of the frictional force is related to the pressure and the roughness only. Thus, when the polishing pad is moved between the a and B positions, the friction force is not changed, i.e., the slow moving speed is maintained between the a and B positions. Therefore, the polishing time of the polishing disc at the position B is too long, the position B is a smooth part, the excessive polishing condition can be caused by too long polishing time, and the polishing effect on the cylinder cover of the automobile engine is further affected. The technical scheme is that when the linear contact is in linear contact with the position A and the position B is moved, the friction force can be changed along with the change, so that the possibility of transitional polishing can be avoided, and the polishing efficiency is improved.
In addition, in order to improve polishing efficiency, in the technical scheme, the length of the polishing layer in the axial direction is larger than the length of the upper surface of the cylinder cover of the automobile engine in the direction perpendicular to the first direction. Therefore, the polishing process of the automobile engine cylinder cover can be completed only through the polishing roller 200, and the polishing disc in the prior art can finish polishing the upper surface of the automobile engine cylinder cover by one horizontal movement, and the diameter of the polishing disc is larger than the width of the upper surface of the automobile engine cylinder cover, so that the contact area between the polishing disc and the upper surface of the automobile engine cylinder cover is further increased, and the possibility of transitional polishing is further increased.
In this specific embodiment, as shown in fig. 1, a gantry 500 is disposed at a middle position of the top of the support 110 in the length direction, vertical sliding grooves 510 are formed on two sides of the gantry 500, a polishing fixing seat 520 is disposed between the two vertical sliding grooves 510, two ends of the polishing fixing seat 520 are slidably connected with the vertical sliding grooves 510 through a sliding block, the polishing roller 200 is rotationally disposed in the polishing fixing seat 520, and a first driving mechanism 300 is disposed between the top of the polishing fixing seat 520 and the top of the inner side of the gantry 500 and is used for driving the polishing fixing seat 520 to move along the length direction of the vertical sliding grooves 510.
In one or more embodiments, the first drive mechanism 300 includes two motorized telescopic rods symmetrically disposed at both ends between the top of the polishing mount 520 and the gantry 500. Of course, the first driving mechanism 300 may be other mechanisms, such as an air cylinder or a hydraulic telescopic cylinder, for driving the polishing holder 520 to move along the length direction of the vertical chute 510.
In this embodiment, as shown in fig. 3, one end of the polishing roller 200 is fixed at one end inside the polishing fixing seat 520 through a bearing seat, the other end of the polishing roller 200 is provided with a rotating column 210 through a connecting disc, the shaft sleeve 410 is rotatably disposed at the outer side of the rotating column 210, the shaft sleeve 410 is fixed at the other end inside the polishing fixing seat 520 through the bearing seat, and the shaft sleeve 410 extends through the side wall of the polishing fixing seat 520 and is fixedly connected with the output end of the driving motor 420.
In this embodiment, as shown in fig. 4-6, the damping assembly 430 includes a stop collar 431 fixed on the outer side of the rotary column 210, a swing rod 432 is vertically disposed on the outer side of the stop collar 431, and a fixing column 433 facing the shaft sleeve 410 is vertically disposed on an end of the swing rod 432 away from the stop collar 431. The damping assembly 430 further includes a positioning block 434, the positioning block 434 is disposed along a tangential direction of the shaft sleeve 410 and is located at one side of the swing rod 432, a sliding groove 435 is formed on one side of the positioning block 434, which is close to the limiting ring 431, and a sliding bar 436 is slidably disposed in the sliding groove 435. One end of the sliding bar 436 extends out of the sliding groove 435 and extends to one side of the fixed column 433, and a bar-shaped hole 437 which is directed to the axis of the shaft sleeve 410 and is adapted to the fixed column 433 is formed.

When the shaft sleeve 410 and the polishing roller 200 relatively rotate, the rotary column 210 moves towards one end of the rotary column 210 in the bar-shaped hole 437 through the swing rod 432, so that the sliding bar 436 moves towards one end of the pressure sensor 439 in the sliding groove 435, and the pressure spring 438 and the pressure sensor 439 are pressed, so that the numerical value of the pressure sensor 439 is changed; that is, when the cylinder head surface is rougher, the larger the angle at which the sleeve 410 and the polishing roller 200 are relatively rotated, the larger the deformation amount of the compression spring 438, the larger the value of the pressure sensor 439; and as the value of the pressure sensor 439 increases, the speed at which the delivery mechanism 100 delivers the vehicle engine head decreases. Compared with the prior art that a torque spring is adopted to identify the change of torque, namely the generated acting force acts on the spiral direction of the torque spring, when the shaft sleeve 410 and the polishing roller 200 of the technical scheme rotate relatively, the sliding strip 436 can convert deflection on the angle of the swinging rod 432 into uniform horizontal force which acts on the axial direction of the compression spring 438 and the pressure sensor 439, and the fatigue resistance and the detection performance are better.
