[0001] The invention relates to the technical field of grinding and polishing, and in particular to a double-station deburring device for an elevator guide rail end. Background Art

[0002] Elevator guide rails are elevator components consisting of steel rails and connecting plates. From the perspective of cross-sectional shape, elevator guide rails are mainly divided into three types: T-shaped, L-shaped and hollow. Among them, T-shaped guide rails are commonly used in elevators because of their strong rigidity, high reliability, safety and low cost. In order to reduce the friction generated by the guide rails, both ends of the guide rails need to be deburred.

[0003] The Chinese patent application number CN201910272030.0 discloses an elevator guide rail deburring device, which includes a manipulator and two feeding devices, which are respectively arranged on both sides of the manipulator.

When the iron ring does not rotate, the baffle is reset under the action of the elastic shaft seat, thereby expanding the blocking ring and causing the debris to fall off; 6. The baffle is used to block the generated debris, and the collection box is used to collect the debris falling from the magnetic component, which is convenient for one-time cleaning.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not used to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of the present invention without substantially changing the technical content.

[0022] Reference Figure 1-Figure 9 , a double-station deburring device for the end of an elevator guide rail, comprising: two symmetrically arranged mounting frames 1, a control box 12 fixed inside the mounting frames 1, and a driving device 2 fixed on the mounting frames 1, wherein the driving device 2 is provided with a grinding device 3, and the grinding device 3 comprises a motor 31, a connecting rod 32 and a grinding end 33, wherein the motor 31 is mounted on the upper end of the driving device 2, the connecting rod 32 is mounted on the output end of the motor 31, and the grinding end 33 is fixedly connected to the end of the connecting rod 32; A magnetic attraction component 4 is arranged on the connecting rod 32, and the magnetic attraction component 4 includes a mounting tube 41, a core sleeve 42, an iron ring 43 and a spiral tube 44. The mounting tube 41 is fixedly sleeved on the connecting rod 32, and the end away from the grinding end 33 is fixedly connected to the connecting rod 32, the core sleeve 42 is sleeved on the connecting rod 32, and is located inside the mounting tube 41, the iron ring 43 is fixedly connected to the end of the core sleeve 42 close to the grinding end 33, and the spiral tube 44 is fixedly arranged between the mounting tube 41 and the core sleeve 42.

[0023] A cleaning assembly 5 is disposed at one end of the spiral tube 44 close to the grinding end 33 , and the cleaning assembly 5 is used to clean the debris collected on the iron ring 43 .

[0024] In the embodiment of the application of the above technical solution, the two mounting frames 1 are symmetrically arranged, and the two grinding devices 3 respectively arranged on the two mounting frames 1 can perform grinding and deburring processing from both ends of the guide rail. During grinding, the connecting rod 32 is driven to rotate by controlling the motor 31, and the grinding end 33 is used for rotational grinding.

[0025] When the motor 31 is driven, the spiral tube 44 is energized, so that the iron core sleeve 42 generates a magnetic field, and magnetism is formed on the surface of the iron ring 43. When the guide rail is deburred, debris will be generated. Since the burr debris is metal debris with a certain volume and weight, the metal debris is magnetically absorbed and collected by the strong magnetism of the iron ring 43. At the same time, the powder debris floating in the air is magnetically absorbed and collected during the movement. When the grinding is completed, the spiral tube 44 is powered off, and the iron ring 43 loses its magnetism, so that the debris falls under the action of gravity.

[0026] The present invention can collect and clean the generated debris during the grinding process, thereby preventing the debris from flying, reducing the use of manual labor, and improving the deburring efficiency.

[0027] The preferred technical solution in this embodiment is: Reference Figure 4 The driving assembly includes a fixed frame 21, a pushing module 22, a horizontal sliding frame 23 and a lifting frame 24. The fixed frame 21 is fixedly installed on one side of the mounting frame 1, the lifting frame 24 is fixedly installed on one side of the fixed frame 21, the horizontal sliding frame 23 is slidably arranged above the lifting frame 24, the pushing module 22 is fixedly connected to the upper end of the horizontal sliding frame 23, and the grinding assembly is fixedly installed on the side of the pushing module 22.

[0028] During the deburring process, the movement of the lifting frame 24, the horizontal sliding frame 23 and the pushing module 22 is controlled by the numerical control module, so that the position movement of the grinding device 3 can be controlled, so that the side ends of guide rails of different shapes can be grinded and deburred, realizing automatic grinding and improving the efficiency of deburring.

[0029] Reference Figure 5-7 The cleaning assembly 5 includes a sliding ring 51, two connecting strips 52 and a cleaning ring 53. The sliding ring 51 is fixedly connected to one end of the spiral tube 44 close to the grinding end 33. Two openings are symmetrically opened on the iron ring 43. The two connecting strips 52 pass through the iron ring 43. The cleaning ring 53 is sleeved on the grinding end 33 and fixedly connected to the end of the connecting strip 52.

[0030] The cleaning ring 53 is made of insulating material, and the inner side close to the grinding end 33 is set to a trapezoidal cross-section, and is in contact with the grinding end 33.

[0031] The debris generated by grinding is magnetically attracted to the iron ring 43 by the magnetic attraction component 4. In order to quickly clean the magnetically attracted debris and prevent the magnetically attracted debris from wearing the iron ring 43 during rotation, a cleaning ring 53 is provided between the iron ring 43 and the debris to avoid direct contact between the debris and the iron ring 43. This can quickly clean the debris and reduce the wear on the iron ring 43.

[0032] When the spiral tube 44 is not energized, the cleaning ring 53 is located at the front end of the grinding end 33 and is not in contact with the iron ring 43. When the spiral tube 44 is energized, the spiral tube 44 will shrink due to the power supply. The shrinking spiral tube 44 drives the sliding ring 51 to move to the side away from the grinding end 33, thereby driving the cleaning ring 53 to move in the direction of the iron ring 43. The cleaning ring 53 contacts the iron ring 43, and the iron ring 43 generates magnetism to magnetically attract the debris generated by grinding, thereby removing the debris generated by grinding. When the grinding is completed, the spiral tube 44 is powered off and reset, causing the cleaning ring 53 to separate from the iron ring 43. The debris is not attracted by the magnet and falls under the action of gravity and is then collected. At the same time, the cleaning ring 53 cleans the debris on the grinding end 33 during the outward movement, thereby preventing the debris from adhering to the grinding end 33. After one grinding is completed, the debris will be collected once, avoiding the accumulation of debris and ensuring the collection effect of the debris.

[0033] In order to prevent the debris from being magnetically attracted to the cleaning ring 53 due to static electricity, the cleaning ring 53 is made of an insulating material to ensure that the debris can fall off after grinding is completed.

[0034] Reference Figure 7-8 The edge of the iron ring 43 is annularly provided with a plurality of shielding components 6, and the plurality of shielding components 6 are used to form a shielding ring. The shielding components 6 include an elastic shaft seat 61 and a side plate 62. The elastic shaft seat 61 is fixedly connected to the outer edge of the iron ring 43, and the side plate 62 is rotatably connected to the elastic shaft seat 61.

[0035] The iron ring 43 is provided with a plurality of sliding openings 9 in an annular shape. Adjustment components 7 are respectively arranged inside the plurality of sliding openings 9 . The adjustment components 7 are used to control the rotation of the side plate 62 .

[0036] The regulating component 7 includes a slider 71, an elastic rope 72, an extrusion bar 73, a deflection bar 74 and a scraping bar 75. The sliding opening 9 and the slider 71 are both I-shaped. The slider 71 is slidably arranged inside the sliding opening 9. One end of the elastic rope 72 is fixedly connected to the side of the slider 71 close to the center of the iron ring 43, and the other end is fixedly connected to the inner side of the sliding opening 9. The extrusion bar 73 is an arc-shaped bar, and is fixedly connected to the side of the slider 71 away from the grinding end 33. The deflection bar 74 is fixedly connected to the side of the side plate 62 away from the grinding end 33. The extrusion bar 73 is used to extrude the deflection bar 74. The scraping bar 75 is fixedly connected to the side of the slider 71 close to the grinding end 33.

[0037] In order to avoid the situation that when the grinding end 33 is being ground, one side of the iron ring 43 is unable to adsorb the debris due to the adsorption of a large amount of debris, thereby affecting the collection of the debris, the core sleeve 42 is fixedly connected to the connecting rod 32 so that the iron ring 43 is rotated, and the debris is evenly distributed on the iron ring 43, thereby ensuring the collection effect of the debris.

[0038] However, since the iron ring 43 rotates, the debris adsorbed on the iron ring 43 will also rotate, and it is easy to be thrown out of the iron ring 43 under the action of centrifugal force, making it impossible to collect the debris. By providing a shielding component 6, the iron ring 43 can block the debris during the rotation process. When the iron ring 43 stops rotating, the debris accumulated on the edge of the iron ring 43 can be quickly cleaned.

[0039] When the iron ring 43 does not rotate, the baffle 10 is located on the same plane as the iron ring 43 through the fixed position of the elastic shaft seat 61. During the rotation of the iron ring 43, the slider 71 will pull the elastic rope 72 due to the outward centrifugal force, so that the slider 71 moves outward, and the extrusion bar 73 squeezes the deflection bar 74 during the movement, so that the side plate 62 is perpendicular to the iron ring 43. Multiple side plates 62 will form a blocking ring located at the edge of the iron ring 43 to block the adsorbed debris. When the iron ring 43 does not rotate, the slider 71 is reset under the elastic pull of the elastic rope 72, the extrusion bar 73 is separated from the deflection bar 74, and the baffle 10 is reset under the action of the elastic shaft seat 61, thereby unfolding the blocking ring to make the debris fall.

[0040] Reference Fig. 9 A positioning assembly 8 is provided on the side of the mounting frame 1 away from the driving device 2, and the positioning assembly 8 is used to move and position the elevator guide rail.

[0041] The positioning assembly 8 includes a positioning frame 81, a positioning plate 82, a telescopic frame 83 and a translation frame 84. The positioning frame 81 is fixedly connected to the middle of the mounting frame 1, the positioning plate 82 is fixedly connected to the side of the positioning frame 81 away from the grinding device 3, the telescopic frame 83 is fixedly installed on the side of the mounting frame 1 away from the driving device 2, and the translation frame 84 is slidably set on the telescopic frame 83.

[0042] Multiple sets of guide rails are rotated by transmission belts. When they reach the specified position, the guide rails are transferred to the translation frame 84 through the telescopic frame 83, and then the translation frame 84 is controlled to slide to clamp the guide rails in the positioning plate 82. After the guide rails are clamped on the positioning plate 82, the ends of the guide rails are polished by the polishing device 3.

[0043] Reference Fig. 9A baffle 10 is arranged in the middle of the positioning frame 81. The baffle 10 is arranged vertically and has an operation opening in the middle for the grinding end 33 to pass through. A collection box 11 is connected to the middle of the positioning frame 81, and the collection box 11 is used to collect grinding debris.

[0044] The baffle 10 is used to block the generated debris, and the collection box 11 is used to collect the debris dropped from the magnetic component, so as to facilitate one-time cleaning.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
