Description
Technical Field

Background
Titanium is a metal with light weight, high strength and corrosion resistance, and is chemically denoted by Ti. Titanium has low density, high melting point and good mechanical properties, and is an ideal structural material and engineering material. Titanium has good corrosion resistance and can be stably used in various mediums such as acid, alkali, oxidant and the like for a long time. The corrosion resistance of the titanium alloy enables titanium to be widely applied to the fields of chemical industry, ocean engineering, aerospace, medical appliances and the like. Titanium is commonly used in industry as a billet in the form of a titanium rod that is processed by a processor into various parts. However, the titanium rod is contacted with air to form an oxide layer with higher hardness, so that the difficulty in processing the titanium rod is increased, and the titanium rod needs to be subjected to rough grinding before being processed so as to remove the oxide layer.
In the current society, a processing staff uses a grinding tool such as a grinding wheel or polishing gauze to grind the titanium rod to remove an oxide layer on the surface of the titanium rod, and the grinding tool cuts into the titanium rod along the radial direction in the process of grinding the titanium rod so as to generate a back force perpendicular to the titanium rod. For example, one of the chinese patent entitled polishing apparatus for removing oxide from titanium rod, having publication No. CN217317472U, uses a spiral rubber roller to support the titanium rod, uses a bar-shaped block to move polishing gauze to make the polishing gauze contact with the oxide layer on the surface of the titanium rod, and starts a servo motor to drive the spiral rubber roller to rotate so as to drive the titanium rod to rotate, and the contact portion between the titanium rod and the polishing gauze is ground during the rotation process of the titanium rod so as to remove the oxide layer of the titanium rod.
The inventor found that the polishing gauze in the prior art always contacts with the titanium rod to generate high temperature during the grinding process, and the phenomenon of surface crystallization may occur after the titanium metal is polished at the high temperature. The surface crystallization of the titanium rod may cause an increase in the roughness of the surface of the titanium rod, thereby affecting the smoothness and the decorativeness of the surface of the titanium rod, and on the other hand, the surface crystallization of the titanium rod may also adversely affect the mechanical properties of the titanium metal, such as hardness and tensile strength. In addition, the titanium rod can generate a spark sputtering phenomenon in the polishing process, and the spark sputtering can cause burn to human skin on the surface of a human body, thereby causing adverse effects on the health of processing personnel.

When the grinding wheel grinds the titanium rod, the back force is transmitted to the third connecting rod through the grinding wheel and is transmitted to the third rotation source through the connecting block, the adapter block and the driving shaft respectively. However, the back force generated by the grinding wheel grinding the titanium rod is reduced by the compression spring, so that the back force transmitted to the driving shaft is smaller than the sum of the pretightening force and the gravity of the third rotation source.

The first spring is released to drive the first spring pressure to release to drive the slide bar to rise, and the slide bar rises to the limit disc to press the reversing button, so that the second rotation source reverses to drive the grinding wheel to be separated from the titanium rod. Finally, the second rotation source drives the sliding rod to descend and reset under the action of self gravity, the sliding rod descends to the bottom of the limiting sleeve to press the forward rotation button, and the motor is driven to continue to rotate forward so that the grinding wheel grinds the titanium rod.
The back force generated by the grinding wheel and the titanium rod enables the supporting plate to drive the first unlocking block to ascend, the locking block is unlocked, and the pressure of the first reset spring is released. In addition, the back force generated by the grinding wheel and the titanium rod is transmitted to the first reset spring to transmit the back force of the grinding wheel and the titanium rod to the sliding rod, so that the sliding rod can ascend to press the reversing button to enable the third rotation source to reversely rotate to drive the grinding wheel to ascend, and the grinding wheel is separated from the titanium rod to stop grinding of the titanium rod.

When the locking block is unlocked, the first reset spring releases the limit of the pressing plate to eject the pressing plate, and the pressing plate drives the sliding rod to eject, so that the sliding rod extrudes the button. At this time, the elastic force of the first reset spring has a certain impact force on the pressing plate, and then has a certain impact on the button. The sliding speed of the sliding rod is slowed down by the vent hole and the sealing plug, and the impact force born by the button can be reduced, so that the probability of damage of the button due to impact is reduced.
Optionally, the drive rod stretches into the second support part is fixedly connected with limiting plate, the second support bottom wall is just right to third rotation source department installs can let the third rotation source stop rotating's brake button.
Through adopting above-mentioned technical scheme, the actuating lever rises in-process, and the limiting plate rises along with the actuating lever, and the limiting plate removes to brake button department and continues to rise and press brake button, and brake button starts and makes the third rotation source stop rotating.
The driving rod can drive the grinding wheel to rise, so that the limiting plate presses the brake button in the rising process to stop the third rotation source from rotating, and the probability of production accidents caused by the fact that the grinding wheel continues to rise and collides with the second bracket is reduced.
Optionally, the supporting mechanism is kept away from second support one end is provided with the observation platform that supplies operating personnel to observe titanium stick processing state, the rotation of observation platform lower extreme is connected with a plurality of can drive the gyro wheel that observation platform axially moved along the titanium stick.
By adopting the technical scheme, when the grinding mechanism polishes the titanium rod, a processing person observes the processing condition of the titanium rod at the observation table. The second support moves along the axial direction of the titanium rod to change the processing position of the titanium rod, and the observation table moves from the roller to the corresponding processing position of the titanium rod to continue observation.
Because the titanium rod can generate sparks in the grinding process, the sparks are sputtered on the surface of the human body to burn the skin of the human body, thereby damaging the health of the processing personnel. The setting of observing the platform can stop the spark and get into the inside of observing the platform to can reduce the probability that the processing personnel is sputtered the spark, improve the processing environment, protect the health safety of processing personnel.

The second bracket 3 drives the grinding mechanism 4 to move to the position where the titanium rod needs to be ground, and the intermittent mechanism 5 drives the grinding mechanism 4 to descend so that the grinding mechanism 4 abuts against the titanium rod to grind. When the grinding tool cuts into the titanium rod, a back force is generated, and the back force is transmitted to the intermittent mechanism 5 through the grinding mechanism 4, so that the intermittent mechanism 5 drives the grinding mechanism 4 to be separated from the titanium rod, and the titanium rod stops being ground and dissipates heat.

Each second sliding groove 571 is slidably provided with a locking block 572, and the portion of the locking block 572 extending out of the second sliding groove 571 along the second sliding groove 571 can extend into the locking groove 561. The side wall of the locking block 572, which is positioned inside the second sliding groove 571, is fixedly connected with a second return spring 573, and one end of the second return spring 573, which is far away from the locking block 572, is fixedly connected with the bottom wall of the sliding rod 57, in which the second sliding groove 571 is arranged. A third supporting rod 58 is vertically and fixedly arranged at two ends of the top wall of the third supporting frame near the locking groove 561 respectively, a first unlocking block 581 is connected to the top end of each third supporting rod 58 in a sliding mode, and the first unlocking blocks 581 can extend into the locking groove 561 to enable the locking blocks 572 to prop out of the locking blocks 572. A second unlocking block 514 is fixedly connected to the two ends of the supporting plate 51 near the third supporting rod 58, and each second unlocking block 514 can move along with the supporting plate 51 to push the first unlocking block 581 into the locking groove 561.
The adjusting nut 513 abuts against the pressing plate 54, and the pressing plate 54 compresses the first reset spring 55, at this time, the compression force of the spring is pretightening force, and the adjusting nut 513 can rotate to control the descending height of the pressing plate 54, so that the pretightening force is adjusted. The third rotation source 52 rotates positively to drive the driving rod 53 to rotate and simultaneously drive the driving rod 53 to descend, the driving rod 53 drives the adapter block 532 to descend, the driving rod 53 extrudes the compression spring 533 to enable the compression spring 533 to generate pressure to extrude the connecting block 534 to descend, the connecting block 534 slides on the third connecting rod 511 and simultaneously drives the third connecting rod 511 to descend, and the third connecting rod 511 drives the grinding wheel 43 to descend to tightly press the side wall of the titanium rod, so that the grinding wheel 43 grinds the titanium rod.
When the grinding wheel 43 grinds the titanium rod, the back force is transmitted to the third link 511 through the grinding wheel 43, and is transmitted to the third rotation source 52 via the connection block 534, the adapter block 532, and the driving lever 53, respectively. However, the back force generated by grinding wheel 43 grinding the titanium rod is reduced by compression spring 533, so that the back force transmitted to drive rod 53 is less than the sum of the preload force and the weight force of third rotation source 52. The third rotation source 52 continues to rotate forward to drive the driving rod 53 to squeeze the compression spring 533, when the compression spring 533 is squeezed to a certain extent, the driving rod 53 abuts against the adapter 532, at this time, the pretightening force is directly transferred to the adapter 532 to the driving rod 53 through the connecting block 534, and the sum of the pretightening force and the gravity of the third rotation source 52 is smaller than the back force, and the back force drives the driving rod 53 to drive the third rotation source 52 to rise.
The third rotation source 52 drives the support plate 51 to rise in the rising process, the support plate 51 drives the two second unlocking blocks 514 to rise, the upper surface of the second unlocking block 514 close to the third support rod 58 is an inclined plane gradually falling along the direction close to the first unlocking block 581, and the lower surface of the second unlocking block 514 close to the third support rod 58 is an inclined plane gradually rising along the direction close to the first unlocking block 581. The upper surface of the second unlocking block 514 abuts against the first unlocking block 581 in the process of ascending the second unlocking block 514, and the second unlocking block 514 is extruded into the locking groove 561 by the inclined plane along with the ascending of the second unlocking block 514, and the locking block 572 is extruded out of the locking groove 561 in the process of the second unlocking block 514 entering the locking groove 561, so that the unlocking of the first reset spring 55 is achieved. The first reset spring 55 is released to drive the slide bar 57 to ascend, the slide bar 57 ascends to the position of the limiting ring 563 to press the reversing button 564, so that the second rotation source 44 reverses to drive the grinding wheel 43 to be separated from the titanium rod. Finally, the second rotation source 44 drives the slide bar 57 to descend and reset under the action of self gravity, the slide bar 57 descends to the bottom of the limit sleeve 56 to press the forward rotation button 562, and the motor is driven to rotate forward continuously to enable the grinding wheel 43 to grind the titanium rod.
The backing force generated by the grinding wheel 43 and the titanium rod causes the support plate 51 to drive the first unlocking block 581 to ascend, unlock the locking block 572, and release the pressure of the first return spring 55. In addition, the back force generated by the grinding wheel 43 and the titanium rod is transmitted to the first return spring 55 to transmit the back force of the grinding wheel 43 and the titanium rod to the slide rod 57, so that the slide rod 57 can ascend to press the reversing button 564 to reversely rotate the third rotation source 52 to drive the grinding wheel 43 to ascend, and the grinding wheel 43 is separated from the titanium rod to stop grinding the titanium rod. Therefore, the intermittent mechanism 5 not only unlocks the locking block 572 by using the back force, but also drives the slide rod 57 to ascend, so that the grinding wheel 43 can be separated from the titanium rod by using the back force necessarily generated by part machining, and the structure has better innovation.
In addition, the adjusting nut 513 moves up and down along the third sliding rod 57 during the rotation of the third connecting rod 511, the adjusting nut 513 abuts against the pressing plate 54, and the first return spring 55 abuts against the pressing plate 54, so that the pressing plate 54 moves up and down, the first return springs 55 can be compressed to different heights during the movement of the pressing plate 54, and the compression force of the first return springs 55 can be changed, so that the pretightening force can be adjusted.
Referring to fig. 6, a vent hole 565 for allowing air to slowly pass through is formed at the lower end of the side wall of each limiting sleeve 56, and a sealing plug 574 is fixedly connected to the bottom surface of each sliding rod 57.
In the sliding process of the slide rod 57 in the limit sleeve 56, the sealing plug 574, the inner side wall and the bottom wall of the limit sleeve 56 form a closed space, the air vent 565 communicates the closed space with the outside atmosphere, when the slide rod 57 slides, air flows through the air vent 565, and because the air in the closed space slowly flows through the air vent 565, the air completely flows out of or flows into the closed space, and a certain time is required in the sliding process, so that the sliding of the slide rod 57 is damped.
When the locking block 572 is unlocked, the first return spring 55 releases the restriction of the pressing plate 54 to eject the pressing plate 54, and the pressing plate 54 drives the sliding rod 57 to eject, so that the sliding rod 57 presses the reversing button 564. At this time, the elastic force of the first return spring 55 has a certain impact force on the pressing plate 54, and thus has a certain impact on the reversing button 564. The vent 565 and the sealing plug 574 reduce the sliding speed of the slide rod 57, and can reduce the impact force applied to the reversing button 564, thereby reducing the probability of damage to the reversing button 564 due to impact.
Referring to fig. 4, a limiting plate 535 is fixedly connected to a portion of the driving rod 53 extending into the second bracket 3, and a brake button 32 capable of stopping rotation of the third rotation source 52 is mounted on a position of the bottom wall of the second bracket 3 opposite to the third rotation source 52.
During the lifting of the driving rod 53, the limiting plate 535 lifts along with the driving rod 53, the limiting plate 535 moves to the position of the brake button 32 to continuously lift to press the brake button 32, and the brake button 32 is started to stop the rotation of the third rotation source 52.
Since the driving rod 53 is lifted to lift the grinding wheel 43, the stop plate 535 is pressed to stop the third rotation source 52 by pressing the brake button 32 during the lifting process, so as to reduce the probability of production accident caused by the collision between the grinding wheel 43 and the second bracket 3.
Referring to fig. 1 and 2, an observation table 6 for an operator to observe the processing state of the titanium rod is arranged at one end of the supporting mechanism 2 away from the second bracket 3, and a plurality of rollers 31 capable of driving the observation table 6 to move along the axial direction of the titanium rod are rotatably connected to the lower end of the observation table 6.
When the grinding mechanism 4 grinds the titanium rod, a worker observes the working condition of the titanium rod on the observation stand 6. The second bracket 3 moves along the axial direction of the titanium rod to change the processing position of the titanium rod, and simultaneously, the observation table 6 moves from the roller 31 to the corresponding processing position of the titanium rod to continue observation.
Because the titanium rod can generate sparks in the grinding process, the sparks are sputtered on the surface of the human body to burn the skin of the human body, thereby damaging the health of the processing personnel. The arrangement of the observation table 6 can prevent sparks from entering the observation table 6, so that the probability that a processing person is sputtered to sparks can be reduced, the processing environment is improved, and the body safety of the processing person is protected.
The embodiment of the application provides a bar polishing device, which is implemented by the following principle: the first support plates 23 and the second support plates 24 rotate, and the second support frame 3 moves to move the polishing device to a position right above the position where the titanium rod needs to be polished. The third rotation source 52 rotates forward to drive the driving rod 53 to descend, and then drive the grinding wheel 43 to descend to polish the titanium rod. At this time, the driving rod 53 continues to lower the compression spring 533 under the drive of the third rotation source 52 until the driving rod 53 abuts the abutment block 532, at which time the titanium rod abuts the grinding wheel 43 and moves the driving rod 53 upward under the drive of the third rotation source 52. The driving rod 53 drives the third rotation source 52, and further drives the support plate 51, the third connecting rod 511 and the pressing plate 54 to move upwards, and in the moving process, the second unlocking block 514 abuts the first unlocking block 581 against the locking groove 561, so that the locking block 572 abuts against the locking groove 561 to unlock the sliding rod 57. The third rotation source 52 is reversed by pressing the reversing button 564 by the lifting of the slide bar 57 Jie Suoshang to lift the grinding wheel 43 off the titanium rod, and then the third rotation source 52 is lowered by its own power to drive the slide bar 57 to press the forward rotation button 562 to continue grinding the titanium rod by the grinding mechanism 4.
