Description

Technical Field

[0001] The present invention belongs to the technical field of the maintenance of the outer wall of tie bars, and relates to a lubricating device for tie bars, in particular to a lubricating device for the outer wall surface of tie bars. Background Art

[0002] A tie bar is a rod-shaped member installed on a machine or a building to play a traction role. In order to ensure the normal use of the tie bar, it is necessary to regularly apply oil lubrication treatment to its outer wall to ensure the guiding stability of the tie bar.

[0003] However, at present, when performing lubricating oil application treatment on the outer wall of the tie bar, the operator needs to hold a corresponding brush to apply the lubricating oil on the surface of the tie bar. Such an operation not only increases the labor consumption of the operator, but also easily causes uneven application of the lubricating oil on the surface of the tie bar, resulting in insufficient stability quality of the tie bar in the mold clamping mechanism and affecting the subsequent normal work.

[0004] After retrieval, as disclosed in a Chinese patent document, a lubricating device for the outer wall surface of a tie bar [Application No.: 202321219176.7; Publication No.: CN220135183U]. A servo motor is fixedly installed on the top surface of this installation frame, a transmission gear is fixedly sleeved on the top surface of the transmission shaft of the servo motor, support rods are fixedly installed on both side surfaces of the top of the installation table, a guiding gear ring is fixedly installed between the top surfaces of the two groups of support rods, and the outer side of the guiding gear ring meshes with the outer side of the transmission gear. Storage tanks are fixedly installed on both ends of the side surface of the installation plate.

[0005] Although the meshing transmission of the transmission gear and the guiding gear ring disclosed in this patent can drive the application brush arranged on the side of the installation plate to rotate synchronously in a circle, however, this device cannot lubricate the working tie bar and has a low automation level.

[0006] Therefore, we propose a lubricating device for the outer wall surface of a tie bar, which can perform automated operations such as stable clamping, automatic enclosing, automatic commutation, dust scraping, and uniform application on the tie bar, with stable operation, good lubrication quality, and high efficiency and convenience. Summary of the Invention

Then the two scraping mechanisms are adjusted in size so that the two scraping mechanisms are not attached to the column to be lubricated, and are driven by the moving mechanism to return to the far right. Then the driving mechanism drives the four flip track mechanisms to move, so that the two scraping mechanisms are flipped at a certain angle. Then the two scraping mechanisms are adjusted in size so that the two scraping mechanisms are again attached to the column to be lubricated. Then the two scraping mechanisms are driven by the moving mechanism to move to the far left, and the two scraping mechanisms cooperate with each other to scrape off the remaining dust on the surface of the column to be lubricated. The scraped dust is collected and returned to the initial position.

[0011] When cleaning the end and applying lubricating oil, the two clamping mechanisms drive the moving mechanism to move away from the Corinthian column, and then the driving mechanism moves to drive the two coating mechanisms and the two scraping mechanisms to flip 180°, and then the two clamping mechanisms drive the moving mechanism to move close to the Corinthian column, and the two coating mechanisms and the two scraping mechanisms re-encircle the Corinthian column driven by the driving mechanism, and the two scraping mechanisms move to adjust their sizes and fit on the surface of the Corinthian column to remove most of the dust on the end, and then the two scraping mechanisms adjust their sizes so that the two scraping mechanisms do not fit on the Corinthian column to be lubricated, and return to the far left driven by the moving mechanism, and then the driving mechanism drives the four flipping track mechanisms to move so that the two The scraping mechanism flips a certain angle, and then the two scraping mechanisms adjust their sizes so that the two scraping mechanisms are re-attached to the Corinthian column to be lubricated, and then the two coating mechanisms and the two scraping mechanisms move to the far right driven by the moving mechanism, and the two scraping mechanisms cooperate with each other to scrape off the remaining dust on the surface of the Corinthian column to be lubricated, and at the same time, the two coating mechanisms adjust their sizes so that the two coating mechanisms are attached to the surface of the Corinthian column to be lubricated, and lubricating oil is applied to the surface of the Corinthian column after cleaning. After the coating is completed, the two scraping mechanisms and the two coating mechanisms no longer fit the surface of the Corinthian column, and then leave the Corinthian column and return to the initial position, and then surround the Corinthian column again, and apply lubricating oil to the remaining end of the Corinthian column.

A support plate is provided on the electric gripper, and the support plate is located between the two arc-shaped jaws.

[0023] With the above structure, when the electric gripper clamps, the anti-slip pads on the two arc-shaped jaws abut against the surface of the to-be-lubricated tie rod, increasing the friction force to prevent sliding. When clamping, the support plate abuts against the surface of the to-be-lubricated tie rod and cooperates with the two arc-shaped jaws of the electric gripper to stably clamp the to-be-lubricated tie rod.

[0041] In this embodiment, the staff places the device on the greasing tie rod to be lubricated. The two clamping mechanisms 4 clamp the greasing tie rod to be lubricated. The moving mechanism 3 drives the driving mechanism 1 to move to the rightmost side. The driving mechanism 1 drives the four flipping track mechanisms 7 to move. The four flipping track mechanisms 7 drive the coating mechanisms 8 and the cleaning mechanisms 6 at the corresponding positions to move. The coating mechanisms 8 on the same side cooperate with each other to surround the outside of the greasing tie rod to be lubricated. The cleaning mechanisms 6 on the same side cooperate with each other to surround the outside of the greasing tie rod to be lubricated. Subsequently, the cleaning mechanisms 6 adjust their sizes according to the size specifications of the greasing tie rod to be lubricated, so that both cleaning mechanisms 6 are attached to the greasing tie rod to be lubricated. Subsequently, the moving mechanism 3 drives the driving mechanism 1 to move to the leftmost side, so that the two cleaning mechanisms 6 move to the leftmost side. The two cleaning mechanisms 6 cooperate with each other to scrape off most of the dust on the surface of the greasing tie rod to be lubricated. Subsequently, the two cleaning mechanisms 6 adjust their sizes so that the two cleaning mechanisms 6 are not attached to the greasing tie rod to be lubricated, and return to the rightmost side under the drive of the moving mechanism 3. Subsequently, the driving mechanism 1 drives the four flipping track mechanisms 7 to move, so that the two cleaning mechanisms 6 flip by a certain angle. Subsequently, the two cleaning mechanisms 6 adjust their sizes so that the two cleaning mechanisms 6 are reattached to the greasing tie rod to be lubricated. Subsequently, the two cleaning mechanisms 6 move to the leftmost side under the drive of the moving mechanism 3. The two cleaning mechanisms 6 cooperate with each other to scrape off the remaining dust on the surface of the greasing tie rod to be lubricated. The scraped dust is collected and returned to the initial position;

[0042] When cleaning the dust at the ends and applying lubricating oil, the two clamping mechanisms 4 drive the moving mechanism 3 to move away from the tie rod. Subsequently, the driving mechanism 1 moves to drive the two coating mechanisms 8 and the two cleaning mechanisms 6 to flip 180°. Subsequently, the two clamping mechanisms 4 drive the moving mechanism 3 to move closer to the tie rod. The two coating mechanisms 8 and the two cleaning mechanisms 6 are driven by the driving mechanism 1 to re-surround the tie rod. The two cleaning mechanisms 6 move to adjust their sizes and attach to the surface of the tie rod to remove most of the dust at the ends. Subsequently, the two cleaning mechanisms 6 adjust their sizes so that the two cleaning mechanisms 6 are not attached to the greasing tie rod to be lubricated, and return to the leftmost side under the drive of the moving mechanism 3. Subsequently, the driving mechanism 1 drives the four flipping track mechanisms 7 to move, so that the two cleaning mechanisms 6 flip by a certain angle. Subsequently, the two cleaning mechanisms 6 adjust their sizes so that the two cleaning mechanisms 6 are reattached to the greasing tie rod to be lubricated. Subsequently, the two coating mechanisms 8 and the two cleaning mechanisms 6 move to the rightmost side under the drive of the moving mechanism 3. The two cleaning mechanisms 6 cooperate with each other to scrape off the remaining dust on the surface of the greasing tie rod to be lubricated. At the same time, the two coating mechanisms 8 adjust their sizes so that the two coating mechanisms 8 are attached to the surface of the greasing tie rod to be lubricated, and lubricating oil is applied to the surface of the tie rod after dust cleaning. After the application is completed, the two cleaning mechanisms 6 and the two coating mechanisms 8 are no longer attached to the surface of the tie rod, and then leave the tie rod and return to the initial position. Subsequently, they surround the tie rod again and apply lubricating oil to the remaining ends of the tie rod.

[0050] In this embodiment, the telescopic ends of a number of electric push rods 21 drive the second fixed seat 27 to move. The second fixed seat 27 drives a number of first connecting rods 23 and a number of first connecting linkages 25 to move, adjusting the distance between the second fixed seat 27 and the first fixed seat 26. When a number of first connecting rods 23 move, the first connecting rods 23 drive the flexible smearing plate 20 to move, thereby adjusting the size of the flexible smearing plate 20 to control the flexible smearing plate 20 to fit the surface of the to-be-lubricated tie rod. After the flexible smearing plate 20 fits on the surface of the to-be-lubricated tie rod, the oil pump 9 sprays the lubricating oil from the oil outlet 28 onto the tie rod, and the flexible smearing plate 20 smears the sprayed lubricating oil on the surface of the tie rod during the movement.

When clamping, the support plate 3 abuts against the surface of the to-be-lubricated tie rod and cooperates with the two arc-shaped grippers of the electric gripper 42 to stably clamp the to-be-lubricated tie rod. The moving mechanism 3 drives the driving mechanism 1 to move to the rightmost side, that is, the moving screw member 39 drives the sliding seat one 11 to move. The sliding seat one 11 drives the rotating motor 40 and the double-threaded screw member 12 to move to the rightmost side. The double-threaded screw member 12 drives the two fixed seats two 27 to move in opposite directions, thereby driving the mounting plates 16 at the corresponding positions and the driving motors 2 and the double-shaft reducers 14 on the mounting plates 16 to move. The mounting plate 16 drives the four flipping slide rails 17 and the arc-shaped sliders 18 at the corresponding positions to move. The four arc-shaped sliders 18 drive the fixed seats one 26 and the fixed seats four 35 at the corresponding positions to move. The coating mechanisms 8 on the same side cooperate with each other to surround the outside of the to-be-lubricated tie rod. The cleaning mechanisms 6 on the same side cooperate with each other to surround the outside of the to-be-lubricated tie rod. That is, the double-threaded screw member 12 drives the two fixed seats two 27 to move in opposite directions, thereby driving the mounting plates 16 at the corresponding positions. The mounting plate 16 drives the fixed seats one 26 and the fixed seats four 35 at the corresponding positions to move. Subsequently, the two fixed seats one 26 on the same side cooperate to form a ring to surround the tie rod. The two fixed seats four 35 on the same side cooperate to form a ring to surround the tie rod. Subsequently, the cleaning mechanism 6 adjusts its size according to the size specification of the to-be-lubricated tie rod so that the two cleaning mechanisms 6 are both attached to the to-be-lubricated tie rod. The telescopic ends of several electric push rods two 32 drive the fixed seat three 30 to move. The fixed seat three 30 drives several connecting rods two 31 and several connecting linkages two 34 to adjust the distance between the fixed seat three 30 and the fixed seat four 35. When several connecting rods two 31 move, several connecting rods two 31 drive the cleaning plates 29 at the corresponding positions to move, adjusting the distance between several cleaning plates 29 to control several cleaning plates 29 to be attached to the surface of the to-be-lubricated tie rod. Subsequently, the moving screw member 39 drives the double-threaded screw member 12 to move to the leftmost side, so that the two cleaning mechanisms 6 move to the leftmost side. The two cleaning mechanisms 6 cooperate with each other to scrape off most of the dust on the surface of the to-be-lubricated tie rod. Subsequently, the two cleaning mechanisms 6 adjust their sizes so that the two cleaning mechanisms 6 are not attached to the to-be-lubricated tie rod and return to the rightmost side under the drive of the moving screw member 39. Subsequently, the driving mechanism 1 drives the four flipping track mechanisms 7 to move, causing the two cleaning mechanisms 6 to flip by a certain angle, that is, the arc-shaped rack 19 drives the arc-shaped slider 18 to slide on the flipping slide rail 17, thereby driving the two cleaning mechanisms 6 to flip by a certain angle. Subsequently, the two cleaning mechanisms 6 adjust their sizes so that the two cleaning mechanisms 6 are re-attached to the to-be-lubricated tie rod. Subsequently, the two cleaning mechanisms 6 adjust their sizes so that the two cleaning mechanisms 6 are re-attached to the to-be-lubricated tie rod. Subsequently, the two cleaning mechanisms 6 move to the leftmost side under the drive of the moving mechanism 3.Two scraping mechanisms 6 cooperate with each other to scrape off the remaining dust on the surface of the greasing column to be lubricated. The scraped dust is collected and returned to the initial position;

[0057] When cleaning the dust at the end and applying lubricating oil, the two clamping mechanisms 4 drive the moving mechanism 3 to move away from the column, that is, the telescopic end of the electric push rod three 41 extends, which in turn drives the moving screw member 39 to move, so that the moving screw member 39 drives the sliding seat one 11 and the rotating motor 40 thereon to move, thereby driving the flexible coating plate 20 and several scraping plates 29 away from the column. Subsequently, the driving mechanism 1 drives the two coating mechanisms 8 and the two scraping mechanisms 6 to flip 180°. Then the two clamping mechanisms 4 drive the moving mechanism 3 to move closer to the column. The two coating mechanisms 8 and the two scraping mechanisms 6 are driven by the driving mechanism 1 to re-surround the column. The two scraping mechanisms 6 move to adjust their sizes and fit on the surface of the column to remove most of the dust at the end. Then the two scraping mechanisms 6 adjust their sizes so that the two scraping mechanisms 6 do not fit on the greasing column to be lubricated, and return to the leftmost side under the drive of the moving mechanism 3. Subsequently, the driving mechanism 1 drives the four flipping track mechanisms 7 to move, so that the two scraping mechanisms 6 flip by a certain angle. Then the two scraping mechanisms 6 adjust their sizes so that the two scraping mechanisms 6 re-fit on the greasing column to be lubricated. Then the two coating mechanisms 8 and the two scraping mechanisms 6 move to the rightmost side under the drive of the moving mechanism 3. The two scraping mechanisms 6 cooperate with each other to scrape off the remaining dust on the surface of the greasing column to be lubricated. At the same time, the two coating mechanisms 8 adjust their sizes so that the two coating mechanisms 8 fit on the surface of the greasing column to be lubricated, that is, the telescopic ends of several electric push rods one 21 drive the fixed seat two 27 to move, and the fixed seat two 27 drives several connecting rods one 23 and several connecting linkages one 25 to move, adjusting the distance between the fixed seat two 27 and the fixed seat one 26. When several connecting rods one 23 move, several connecting rods one 23 drive the flexible coating plate 20 to move, thereby adjusting the size of the flexible coating plate 20 to control the flexible coating plate 20 to fit on the surface of the greasing column to be lubricated, and apply lubricating oil on the surface of the column after dust cleaning. After the application is completed, the two scraping mechanisms 6 and the two coating mechanisms 8 do not fit on the surface of the column, then leave the column and return to the initial position, and then surround the column again to apply lubricating oil to the remaining end of the column.

[0058] In summary, through the cooperation of the two clamping mechanisms 4, the greasing column to be lubricated is stably clamped to ensure the stable operation of the device. When adjusting the direction, the driving mechanism is separated from the column, which is convenient for dust cleaning and lubricating oil application;

[0059] The driving mechanism 1 provides power to surround the two scraping mechanisms 6 and the two coating mechanisms 8 outside the column, which is convenient for dust cleaning and lubricating oil application, and cooperates with the two clamping mechanisms 4 to adjust the direction, which is convenient for dust cleaning and lubricating oil application at the end of the column and ensures the lubrication quality;

[0060] Two scraping mechanisms 6 are attached to the surface of the tie bar, cooperate with the moving mechanism 3 to scrape off most of the dust on the surface of the tie bar to be lubricated, and cooperate with the flipping track mechanism 7 to scrape off the remaining dust on the surface of the tie bar to be lubricated, ensuring the lubrication quality.

[0061] Two coating mechanisms 8 are attached to the surface of the tie bar, cooperate with the moving mechanism 3, and the coating mechanisms 8 evenly coat the lubricating oil on the surface of the tie bar, which is efficient and convenient.
