Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
Referring to fig. 1 to 14 together, the polishing apparatus 1 includes a base assembly 2, a polishing head assembly 3 and a dust removing assembly 4. The base assembly 2 may be used to adjust the height of the sanding head assembly 3 disposed thereon, the sanding head assembly 3 being used to sand a surface to be sanded, and the sanded debris or dust being collected by the dust collection assembly 4.
In order to improve the mobility of the polishing apparatus 1, as shown in fig. 1, the polishing apparatus 1 may be installed on a manually operated cart, or may be installed on a self-moving apparatus capable of automatically moving, depending on the use requirement of the polishing apparatus 1.
The base assembly 2 will be described first. As shown in fig. 2-5, in this embodiment, the base assembly 2 may be used to adjust the height of the sanding head assembly 3 so that the sanding head assembly 3 is self-adapting to the height of the surface to be sanded. Specifically, the base assembly 2 includes a housing 21, a lock cylinder 22, a lift table 23, a pilot rod 24, a floating cylinder 25, and a pivot 26.
The housing 21 has a circuit switch, in this embodiment, all the related control buttons of the polishing apparatus 1 are integrated into the circuit switch on the housing 21, and the user can control the operation of each component of the polishing apparatus 1 through the aforementioned circuit switch, while in other embodiments, the control buttons of each component can be provided separately, and this is not limited herein.
Describing the structural composition of the base assembly 2 in detail, the locking cylinder 22 is fixedly disposed on the housing 21, for example, the cylinder of the locking cylinder 22 is fixedly disposed on the housing 21, and the piston rod of the locking cylinder 22 is fixedly connected to the lifting platform 23, so that the lifting platform 23 can be driven to move up and down by the operation of the locking cylinder 22 (the up-and-down movement of the piston rod) to match the working height required by the sanding head assembly 3.
In order to ensure the stable direction of the lifting platform 23 during the up-and-down movement, at least one guiding rod 24 is further disposed on one side of the lifting platform 23 located on the locking cylinder 22, as shown in fig. 4, a corresponding through hole is disposed on the housing 21, and 4 guiding rods 24 extend into the housing 21 through the through holes, thereby ensuring the stable direction of the lifting platform 23 during the height adjustment.
However, since the surface to be ground by the grinding device 1 is not generally a flat surface, often a curved surface (e.g., an arc-shaped surface of the bottom of an airplane) or a slope with a certain drop and continuity in the height of the bottom, and the lock cylinder 22 is generally used for a wide range of up-and-down adjustment, the floating cylinder 25 is also required to accurately adjust the height of the grinding head assembly 3. The floating cylinder 25 is fixed on the housing 21 and is suspended on the pivot member 26 through a suspension member 251, for example, on a shaft 262, and the pivot member 26 is pivotally connected to a corresponding pivot seat 231 (generally 2) on the lifting platform 23 through a pivot shaft 261.
Thus, the internal pressure of the floating cylinder 25 is controlled by using a precise pressure regulating valve and an overflow valve, so that the required pressure is ensured in the floating cylinder 25, when the polishing head assembly 3 is raised, the pressure in the floating cylinder 25 is reduced, the air is supplemented through the pressure regulating valve, so that the floating cylinder 25 floats upwards to drive the pivoting piece 26 to float upwards, and finally the pivoting piece 26 is driven to pivot to realize the raising of the polishing head assembly 3; similarly, when the sanding head assembly 3 is lowered, the internal pressure of the floating cylinder 25 increases, which allows for constant internal pressure and automatic change of height through relief valve venting. Thus, through the arrangement of the floating cylinder 25, the polishing head assembly 3 can be ensured to be always kept in constant-force stable contact with the polishing surface, and the polishing effect is better.
That is, the base assembly 2 realizes a large-scale height adjustment through the locking cylinder 22, and realizes an automatic height fine adjustment through the floating cylinder 25, so that a constant force height self-adapting function of the polishing device 1 can be realized, the contact with the polishing surface is more stable, and the polishing effect is better.
The sanding head assembly 3 is described next. As shown in fig. 1 and 7 to 14, in the present embodiment, the sanding head assembly 3 includes a protective hood 30, a multi-position cylinder 31, a rack 32, a carrier 33, a gear 34, a gear shaft 35, a rotary member 36, a sanding head connecting seat 37, a sanding head rotary seat 38 and a sanding head 39. Moreover, the base assembly 2 has the height adjusting function, but in other embodiments, the base assembly 2 may not have the height adjusting function; if the base assembly 2 has the height adjustment function described above, the sanding head assembly 3 may be a conventional sanding head without the rotation function described below.
In the present embodiment, the hood 30 is an organ type hood, so that the requirement of increasing the polishing range by the rotation of the polishing head assembly 3 can be satisfied. The multi-position cylinder 31 and the rack 32 are synchronously arranged, that is, the multi-position cylinder 31 can drive the rack 32 to synchronously move. The carrier 33 is fixed on the pivot member 26, as shown in fig. 10, the carrier 33 has a through hole 331 through which the rack 32 can pass and a gear space 332 for carrying the gear 34, and the gear space 332 further has a corresponding through hole for the gear shaft 35 to pass through the carrier 33 and the gear 34 together.
In the present embodiment, the rack 32 is, for example, a cylindrical rack, and the cylindrical rack is provided with a rack engaged with the gear 34. Moreover, the pivot member 26 is also provided with a through hole 263 corresponding to the rack 32, so that the rack 32 is inserted into the through hole 263 of the pivot member 26 and the through hole 331 of the carrier 33, thereby ensuring that the moving direction of the rack 32 is kept stable, and ensuring that the rack 32 can be always meshed with the gear 34.
When the multi-position cylinder 31 moves the rack 32, the rack 32 rotates the gear 34 engaged therewith, so that the gear shaft 35 fixed to the gear 34 also rotates, and further rotates the rotary member 36 fixed to the gear shaft 35, and the rotary member 36 is, for example, Contraband-type clamping design to be fixed to the gear shaft 35. Finally, the rotating member 36 rotates the polishing head 39 to increase the polishing range, and the rotation direction of the polishing head 39 is parallel to the plane of the gear 34.
In other words, the multi-position cylinder 31 drives the rack 32 to move linearly, and the above-mentioned linear movement is converted into a rotational movement by the gear 34 engaged with the rack 32. The sanding range is increased by the rotation of the sanding head 39 (roughly understood as right-left rotation), and the sanding effect is stabilized by the coaxial rotation. Specifically, the multi-position cylinder 31 is, for example, a two-position cylinder, that is, it is stopped at three positions, so that the sanding head 39 can rotate around the gear shaft 35, and thus the sanding range thereof becomes large, and the rotation radius of the sanding head 39 can be determined according to the use requirement because the sanding range is proportional to the distance (rotation radius) between the sanding head 39 and the gear shaft 35. And the polishing head 39 can keep a coaxial state at the starting point, the middle point and the end point, and the polishing effect is stable. In addition, the multi-position cylinder 31 can adjust the speed of the cylinder through a speed regulating valve, and further adjust the grinding rotation speed of the front grinding head 39.
In order to make the polishing head 39 fit to the polishing surface in real time, a rotating shaft 371 is disposed on the polishing head connecting seat 37 fixedly connected to the rotating member 36, the other end of the rotating shaft 371 is fixedly connected to the polishing head rotating seat 38, and the polishing head rotating seat 38 can rotate around the rotating shaft 371, i.e. the rotating shaft 371 is perpendicular to the polishing head rotating seat 38. The polishing heads 39 are disposed on the polishing head rotary base 38, for example, two polishing heads 39 are provided, and when the polishing heads 39 work, the rotary shaft 371 can be driven to rotate by the adhesion force between the polishing heads 39 and the polishing surface, so that the polishing heads 39 can be ensured to adhere to the polishing surface in real time, and the polishing heads can be better adapted to polishing of an inclined plane with a certain drop and continuity in height of the arc surface or the bottom. In some embodiments, the polishing apparatus 1 may have only the function of real-time attachment, but not the above-mentioned height adjustment or selection function, i.e., the polishing apparatus 1 may also select a common base assembly or a polishing head assembly without rotation function on the basis of real-time attachment. For example, the sanding head attachment base 37 is secured to the base assembly 2.
In this embodiment, the polishing head connecting seat 37 is further provided with a limiting block 372, so that the rotation angle of the polishing head 39 is within a certain range. As shown in fig. 14, the number of the stoppers 372 is two, and the central axes of the two stoppers 372 pass through the rotation axis 371, that is, the stoppers 372 are symmetrically disposed about the rotation axis 371.
In summary, the polishing device of the present invention utilizes the polishing head assembly capable of rotating left and right to increase the polishing range, and the coaxial arrangement thereof can ensure good polishing effect. Further, the base component in the polishing device realizes large-scale height adjustment through the locking cylinder, and realizes automatic height fine adjustment through the floating cylinder, so that the constant-force height self-adaption function of the polishing device can be realized, the contact with the polishing surface is more stable, and the polishing effect is better. Furthermore, the polishing head assembly can rotate under the action of the bonding force between the polishing head and the polished surface, so that the polishing head can be bonded with the polished surface in real time.
It should be understood that although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description is for clarity only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can also be combined appropriately to form other embodiments understood by those skilled in the art.
The above-listed detailed description is only a specific description of a possible embodiment of the present invention, and they are not intended to limit the scope of the present invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included in the scope of the present invention.
