Detailed Description
The drawings are for illustrative purposes only and are not to be construed as limiting the present patent; for the purpose of better illustrating the present embodiment, certain elements of the drawings may be omitted, enlarged or reduced and do not represent the actual product dimensions.
It will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The technical scheme of the invention is further described below with reference to the accompanying drawings and examples.
The polishing device suitable for stainless steel tableware comprises a frame 1 and a polishing head 2, wherein a driven wheel 3 is rotatably connected to the frame 1, a power mechanism in transmission connection with the driven wheel 3 is arranged on the frame, a spline hole penetrates through the axis of the driven wheel 3, a rotary shaft 4 is slidably connected in the spline hole, the bottom end of the rotary shaft 4 is integrally connected with the axis of the polishing head 2, and a damping mechanism 5 is arranged at the top end of the rotary shaft 4;
The damping mechanism 5 comprises an excitation wire group 51 integrally sleeved at the bottom of the rotating shaft 4 and an induction wire group 52 integrally sleeved at the top of the rotating shaft 4, the excitation wire group 51 is electrically connected with the induction wire group 52, an annular permanent magnet sleeve 53 is sleeved at the outer side of the induction wire group 52, and the permanent magnet sleeve 53 is integrally connected with the frame 1;
the induction line group 52 can cut the magnetic induction line of the permanent magnet cover 53 in the process of reciprocating up and down along with the rotation shaft 4.
When the power mechanism drives the rotary shaft 4 to rotate through the driven wheel 3, the polishing head 2 at the bottom end of the rotary shaft 4 polishes stainless steel tableware, the polishing head 2 can vibrate due to uneven material removal of the polishing head 2, and then the rotary shaft 4 is driven to reciprocate up and down, so that the induction line group 52 on the rotary shaft 4 cuts the magnetic induction line of the permanent magnet sleeve 53, part of kinetic energy of the rotary shaft 4 is converted into electric energy, and vibration caused by the polishing head 2 is reduced and transmitted to other parts.
Stainless steel tableware may have residual magnetism due to mechanical deformation, heat treatment and other factors during the course of rough machining, and the residual magnetism of stainless steel tableware may have some undesirable effects on the use of stainless steel tableware, so that the stainless steel tableware after rough machining needs to be demagnetized. While it is known that a diminishing alternating magnetic field can to some extent eliminate remanence in the material.
As described above, the induction wire group 52 of the present embodiment cuts the magnetic induction wire of the permanent magnet sleeve 53 to generate a current, and the current is transferred to the excitation wire group 51, so that the excitation wire group 51 is electrified and generates a magnetic field. Because the induction line group 52 reciprocates up and down, the current direction on the induction line group 52 also changes alternately, and along with the improvement of the smoothness of the polished stainless steel tableware, the vibration generated by the polishing head 2 is gradually reduced, so that the current generated by the induction line group 52 is also gradually reduced, the exciting line group 51 generates a gradually reduced alternating magnetic field, the effect of demagnetizing the polished tableware is further achieved to a certain extent, and other power supplies are not required to be externally connected to the exciting line group 51, thereby being beneficial to saving electric energy.
It can be seen that the present embodiment not only can reduce the vibration caused by the sanding head 2 from being transmitted to other components, but also achieves the purpose of demagnetizing the sanded tableware to a certain extent.
Specifically, the power mechanism (not shown in the drawings) of the present embodiment includes a motor, wherein a driving wheel is integrally connected to a rotation shaft of the motor, and the driving wheel and the driven wheel 3 are connected through a transmission chain.
Preferably, the damping mechanism 5 further comprises a pressure cavity extending along the axial line of the rotating shaft 4, the pressure cavity is slidably and hermetically connected with a piston head 55, the piston head 55 divides the pressure cavity into an upper cavity 541 and a lower cavity 542, a piston rod 56 coincident with the axial line of the rotating shaft 4 is integrally connected to the piston head 55, and one end of the piston rod 56 extends to the outside of the pressure cavity and is rotatably connected with the rotating shaft 4 through a rolling bearing. It will be appreciated that as another example, the pressure chamber may be flushed with high pressure gas to cushion the movement of the piston head 55, thereby reducing the transmission of vibrations caused by the piston head 55 to other components. Specifically, the damper mechanism 5 further includes a cylinder in which the pressure chamber is formed. And since the specific connection structure of the piston head 55, the piston rod 56 and the cylinder is well known to those skilled in the art, it is not further described in the present specification.
As the embodiment, the pressure chamber stores the cooling liquid, an elastic member 57 is connected between the piston head 55 and the pressure chamber, a first liquid drain channel 561 extending along the axis of the piston rod 56 is formed in the piston rod 55, an upper liquid guide channel 551 communicating the upper chamber 541 and the first liquid drain channel 561 is formed at the top end of the piston head 55, a first upper check member 58 is arranged in the upper liquid guide channel 551, the first upper check member 58 is used for limiting the fluid from entering the upper chamber 541 from the first liquid drain channel 561, a lower liquid guide channel 552 communicating the lower chamber 542 and the first liquid drain channel 561 is formed at the bottom end of the piston head 55, a first lower check member 59 is arranged in the lower liquid guide channel 552, and the first lower check member 59 is used for limiting the fluid from entering the lower chamber 542 from the first liquid drain channel 561;
the upper cavity 541 and the lower cavity 542 are connected to the liquid storage cavity 63 through a second upper check member 61 and a second lower check member 62, respectively, the second upper check member 61 being configured to restrict fluid from entering the liquid storage cavity 63 from the upper cavity 541, and the second lower check member 62 being configured to restrict fluid from entering the liquid storage cavity 63 from the lower cavity 542;
A second drain channel 41 extending along the axis of the rotation shaft 4 and communicating with the first drain channel 561 is formed in the rotation shaft 4, and a drain hole 21 communicating with the second drain channel 41 is formed in the axis of the polishing head 2.
Specifically, the vibration of the sanding head 2 can be decomposed into upward and downward movements of the sanding head 2. When the sanding head 2 moves upward, the sanding head 2 drives the piston head 55 to move upward through the rotating shaft 4 and the piston rod 56, so that the volume of the upper cavity 541 is reduced, the volume of the lower cavity 542 is increased, and then the cooling liquid in the upper cavity 541 enters the first liquid drain channel 561, and the cooling liquid in the liquid storage cavity 63 enters the lower cavity 542. Conversely, when the sanding head 2 moves downward, the sanding head 2 drives the piston head 55 to move downward through the rotating shaft 4 and the piston rod 56, so that the volume of the upper cavity 541 is increased, the volume of the lower cavity 542 is decreased, and then the cooling liquid in the liquid storage cavity 63 enters the upper cavity 541, and the cooling liquid in the lower cavity 542 enters the first liquid drain 561.
The cooling liquid introduced into the first liquid drain 561 flows to the second liquid drain 41 by gravity, and finally flows into the contact portion of the sanding head 2 and the stainless steel tableware through the liquid drain hole 21.
It should be noted that, the cooling liquid spray head of the existing polishing device is disposed at the outer side of the polishing head 2, and in the polishing process, the cooling liquid sprayed by the cooling liquid spray head is often difficult to effectively enter the contact position between the polishing head 2 and the stainless steel tableware due to the action of the centrifugal force generated by the rapid rotation of the polishing head 2. In the present embodiment, the liquid drain hole 21 is disposed at the axis of the polishing head 2, and during polishing, the centrifugal force generated by the rapid rotation of the polishing head 2 can act on the cooling liquid flowing out from the liquid drain hole 21, so that the cooling liquid flows through the contact portion between the polishing head 2 and the stainless steel tableware at a relatively high speed, thereby rapidly taking away the heat and the chips between the polishing head 2 and the stainless steel tableware, being beneficial to preventing the polishing head 2 from overheating and improving the polishing quality.
In addition, when the cooling liquid flows through the second liquid drain channel 41, heat transferred to the rotating shaft 4 by the induction line group 52 and the excitation line group 51 is taken away, so that the induction line group 52 and the excitation line group 51 are cooled, and the operation stability of the induction line group 52 and the excitation line group 51 is guaranteed.
It will be appreciated that the amount of coolant that enters the first fluid passageway 561 from the pressure chamber is affected by the magnitude of the up and down reciprocation of the piston head 55. In the initial stage of polishing, since the surface of the stainless steel tableware is rough, the heat and debris amount at the contact position of the polishing head 2 and the stainless steel tableware are also large, and at this time, the movement range of the piston head 55 is also large, so that more cooling liquid enters the first liquid drain channel 561, and the amount of cooling liquid flowing through the contact position of the polishing head 2 and the stainless steel tableware is also large, thereby rapidly taking away the heat and debris between the polishing head 2 and the stainless steel tableware. In the latter stage of polishing, the contact part of the polishing head 2 and the stainless steel tableware has less heat and less chips because the surface of the stainless steel tableware is smooth, and the movement amplitude of the piston head 55 is smaller, so that the amount of the cooling liquid entering the first liquid drain 561 is reduced. Therefore, the embodiment can automatically adjust the liquid discharge amount of the cooling liquid according to the polishing degree, thereby being beneficial to saving the cooling liquid and reducing the production cost of the stainless steel tableware.
Specifically, the first upper check member 58, the first lower check member 59, the second upper check member 61, and the second lower check member 62 are all check valves, and this type of check valve is well known to those skilled in the art, and will be further described herein.
In order to improve the centrifugal acceleration of the cooling liquid flowing out from the liquid discharge hole 21 so as to ensure that the cooling liquid can smoothly enter the contact part of the polishing head 2 and the stainless steel tableware, a cone-shaped liquid throwing piece 22 is integrally connected in the liquid discharge hole 21, a liquid throwing channel is formed between the liquid discharge hole 21 and the liquid throwing piece 22, an inclined part 23 is formed at the bottom end of the polishing head 2 at the liquid discharge hole 21, the bottom end of the liquid throwing piece 22 is higher than the bottom end of the polishing head 2, and the top point of the inclined part 23 is higher than the bottom end of the liquid throwing piece 22.
Preferably, the outer side of the grinding head 2 is sleeved with a protection ring 71, which can prevent coolant and scraps driven by the grinding head 2 from splashing at a large angle, and damage the eyes of an operator. Second, friction between the sanding head 2 and the stainless steel cutlery generates a lot of heat, causing part of the cooling liquid to change from liquid to vapor. If the vaporous cooling liquid is inhaled by the operator, the respiratory tract of the operator is damaged, in order to avoid the phenomenon, an air inlet channel 711 is formed between the protecting ring 71 and the polishing head 2, the top end of the polishing head 2 is integrally connected with a wind wheel 72 acting on the air inlet channel 711, a gas collecting cover is connected between the rotating shaft 4 and the protecting ring 71, and an air inlet hole 42 for communicating the second liquid drain 41 with the inside of the gas collecting cover is penetrated on the rotating shaft 4. During polishing, the wind wheel 72 can rotate rapidly along with the polishing head 2, and vapor cooling liquid outside the polishing head 2 is sucked into the gas collecting hood through the air inlet channel 711. Subsequently, the vaporous cooling liquid in the gas collecting hood re-enters the second liquid drain channel 41 through the gas inlet hole 42 and is mixed with the liquid cooling liquid in the second liquid drain channel 41, so that the vaporous cooling liquid caused by the overflow of the vaporous cooling liquid is effectively prevented from being inhaled by an operator. In addition, in order to prevent the coolant in the second drain 41 from being thrown away, a sidewall of the second drain 41 is formed with a baffle wall 43 extending downward and shielding the air intake hole 42.
Preferably, the gas-collecting channel comprises a supporting frame 731 for connecting the guard ring 71 and the rotary shaft 4 into a whole, an elastic sleeve 732 is covered on the outer side of the supporting frame 731, the top end of the elastic sleeve 732 is integrally connected with the supporting frame 731, and the bottom end of the elastic sleeve 732 is integrally connected with the guard ring 71. Specifically, the supporting frame 731 includes a supporting plate integrally sleeved on the outer side of the rotating shaft 4, and the bottom end of the supporting plate is integrally connected with the protecting ring 71 through a supporting beam, wherein the bottom end of the elastic sleeve 732 is integrally connected with the supporting plate. The guard ring 71 is provided with a non-return ring 74, and the non-return ring 74 is used to restrict fluid flow from the interior of the gas-collecting channel to the exterior via an inlet channel 711. It can be appreciated that during polishing, the elastic sleeve 732 will rotate rapidly along with the polishing head 2, so that the elastic sleeve 732 will expand under the action of its own centrifugal force, and the elastic sleeve 732 will tend to shrink to its original state. When polishing is completed, the polishing head 2 stops rotating immediately (if the polishing head 2 rotates under the action of inertia after polishing is completed, the safety of operators nearby is endangered, so the polishing head 2 of the present embodiment stops rotating immediately after polishing is completed), and the elastic sleeve 732 rapidly contracts to an original state and applies pressure to the air inside. Due to the presence of the check ring 74, air cannot flow from the inside of the hood to the outside through the inlet duct 711. Then, during the process of contracting the elastic sleeve 732 to the original state, the air inside thereof passes through the air inlet hole 42, the second fluid discharge channel 41 and the fluid discharge hole 21 in order, and is finally sprayed to the stainless steel tableware just finished with the sanding. This helps to blow away the cooling liquid and debris that remain on the exterior of the stainless steel cutlery, which serves to clean the exterior of the stainless steel cutlery.
Specifically, the check ring 74 is an elastic ring having a V-shaped cross-sectional profile, one end of which is integrally connected to the guard ring 71, and the other end of which abuts against the polishing head 2.
Preferably, the frame 1 is provided with a dial indicator 81, a meter rod of the dial indicator 81 points to the excitation wire group 51 and is integrally connected with a permanent magnet column 82, and when the excitation wire group 51 is electrified, magnetic acting force is generated on the permanent magnet column 82.
Specifically, during the polishing process, the induction wire set 52 cuts the induction wire of the permanent magnet sleeve 53, thereby generating an alternating current, and the alternating current is transferred to the excitation wire set 51, so that the excitation wire set 51 is electrified and generates an alternating magnetic field. Under the action of the alternating magnetic field, the permanent magnet column 82 drives the dial indicator rod of the dial indicator 81 to move, so that the pointer of the dial indicator 81 jumps. When stainless steel tableware is gradually polished smoothly, the vibration of the polishing head 2 is weakened, so that the current generated by the induction line set 52 becomes smaller, the alternating magnetic field generated by the excitation line set 51 becomes weaker, and correspondingly, the jump amplitude of the pointer of the dial indicator 81 becomes smaller. Based on this principle, the operator can know the finish degree of polishing of the stainless steel tableware by observing the jump amplitude of the pointer of the dial indicator 81.
It is understood that the specific structure of the dial indicator 81 of the present embodiment is well known to those skilled in the art, and thus the description thereof will not be further described.
It is to be understood that the above examples of the present invention are provided by way of illustration only and not by way of limitation of the embodiments of the present invention. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the invention are desired to be protected by the following claims.
