Description

Technical Field

[0001] The present invention relates to the technical field of processing of hoist accessories, and specifically to an intelligent positioning device for processing hoist accessories. Background Technique

[0002] A hoist is a light and small lifting device that winds a wire rope or chain around a drum to lift or tow heavy objects. It is also called a winch. Hoists are divided into manual hoists and electric hoists, etc. Now, electric hoists are mainly used. They can be used alone or as components in machinery such as lifting and road construction and mine hoisting. They are mainly used for material lifting or flat towing in construction and docks, etc. The structure of a hoist is complex and consists of multiple accessories. When processing accessories, it is necessary to position and fix the hoist accessories for processing.

[0003] There are a wide variety of hoist accessories. Traditional jigs need to design special tooling for different specifications. When changing models, it is necessary to disassemble / install stoppers and re-calibrate the reference plane. The average switching time exceeds 40 minutes, which seriously restricts the multi-variety and small-batch production mode. Moreover, it requires operators to manually calibrate based on experience, resulting in low processing efficiency and poor accuracy.

[0047] The air chamber 19 is connected with a pump body 20 through a pipeline. The pump body 20 is fixedly connected to the fixed ring 13. The pump body 20 sucks air from the air chamber 19. After the air pressure in the air chamber 19 decreases, the air holes 18 are further sucked, thereby forming a negative pressure at the air holes 18 to adsorb the fittings.

[0048] A circular guide rail module one 21 is fixedly connected to the side of the fixed ring 13 away from the turntable 6;

[0049] Such as Figure 5 , the circular guide rail module one 21 includes a circular guide rail one 22.

[0050] A driving motor two 25 is fixedly connected to the upper side of the sliding seat one 23. The output end of the driving motor two 25 is fixedly connected with a gear two 26. A gear ring two 27 is fixedly connected to the circumferential outer wall of the circular guide rail one 22. The gear two 26 is matched with the gear ring two 27, so that the driving motor two 25 drives the sliding seat one 23 to move on the circular guide rail one 22;

[0051] Electromagnets that can control opening and closing are embedded on both sides of the sliding seat one 23 close to the circular guide rail one 22. The electromagnets generate magnetic force when turned on and are magnetically attracted and locked with the circular guide rail one 22, so as to lock and fix the sliding seat one 23.

[0052] A clamping assembly 28 is arranged on each sliding seat one 23. The clamping assembly 28 includes a connecting block one 29. The connecting block one 29 is rotatably connected to the sliding seat one 23. A circular hole is opened on the connecting block one 29. A hydraulic telescopic cylinder four 30 is arranged in the circular hole.

[0054] On the lower side of each second sliding seat 33, four second rollers 34 are rotatably connected to the "I"-shaped groove of the arc-shaped guide rail 32 corresponding thereto. The four second rollers 34 are symmetrically arranged in two groups with the perpendicular bisector of the cross-sectional shape of the arc-shaped guide rail 32 as the reference, so that the second sliding seat 33 slides on the arc-shaped guide rail 32;

[0055] A third driving motor 35 is fixedly connected to the upper side of the second sliding seat 33. The output end of the third driving motor 35 penetrates through the second sliding seat 33 and is fixedly connected with a third gear 36. An arc-shaped gear rack 37 is fixedly connected to the circumferential outer wall of the arc-shaped guide rail 32. The third gear 36 is matched with the arc-shaped gear rack 37, so that the second sliding seat 33 is driven to move on the arc-shaped guide rail 32 by the third driving motor 35;

[0056] Electromagnets that can control opening and closing are embedded on both sides of the lower side of the second sliding seat 33 close to the arc-shaped guide rail 32. The electromagnets generate magnetic force to magnetically lock with the arc-shaped guide rail 32 when turned on, so as to lock and fix the second sliding seat 33;

[0057] The center of the arc-shaped guide rail 32 is concentric with the rotation axis of the first connecting block 29. In this way, by driving the slider 31 to move, the fourth hydraulic telescopic cylinder 30 is driven to rotate around the axis of the first connecting block 29.

[0059] A suction plate 39 is fixedly connected to the side of the clamping block 38 close to the turntable 6. The suction plate 39 is located on the side of the clamping block 38 away from the center disc 12. The suction plate 39 is in direct contact with the support block 16. After the clamping block 38 radially clamps the fitting, the air holes 18 adsorb the suction plate 39 to improve the clamping stability of the clamping block 38 on the fitting.

[0060] Such as Figure 6 , on the side of the fixed ring 13 away from the turntable 6, a second circular guide rail module 40 is provided;

The four third rollers 43 are symmetrically arranged in two groups with the perpendicular bisector of the cross-sectional shape of the second circular guide rail 41 as the reference, so that the third sliding seat 42 slides on the second circular guide rail 41;

[0062] A driving motor four 44 is fixedly connected to the upper side of the third sliding seat 42. The output end of the driving motor four 44 penetrates through the third sliding seat 42 and is fixedly connected with a gear four 45.

[0063] On both sides of the lower side of the third sliding seat 42 close to the circular guide rail two 41, electromagnets that can control opening and closing are embedded. By generating magnetic force when the electromagnets are turned on, magnetic attraction locking is carried out with the circular guide rail two 41, so as to lock and fix the third sliding seat 42.

[0064] On one side of the circular guide rail two 41 close to the fixed ring 13, a number of hydraulic telescopic cylinders five 47 are arranged. The number of hydraulic telescopic cylinders five 47 is evenly distributed in a circle with the central axis of the fixed ring 13 as the reference.

The fixed ends of the hydraulic telescopic cylinders five 47 are fixedly connected in the installation holes, and the output ends of the hydraulic telescopic cylinders five 47 are fixedly connected with the circular guide rail two 41.

[0065] On one side of the third sliding seat 42 away from the circular guide rail two 41, a pressing and fixing assembly is arranged. The pressing and fixing assembly includes a connecting block two 48. The connecting block two 48 is fixedly connected to the third sliding seat 42.

The output end of the hydraulic telescopic cylinder six 55 is fixedly connected with a pressing block 56. A pressure sensor two is embedded in the pressing block 56.

[0067] On the side of the connecting bar 50 away from the turntable 6, a hydraulic telescopic cylinder seven 58 is arranged. A fixing rod 57 is fixedly connected to the upper side of the connecting block two 48. One end of the fixing rod 57 away from the connecting block two 48 is hinged to the fixed end of the hydraulic telescopic cylinder seven 58. The upper part of the side of the connecting bar 50 facing the center of the circular guide rail two 41 is hinged to the output end of the hydraulic telescopic cylinder seven 58;

[0068] The triangular structure of the hydraulic telescopic cylinder seven 58, the fixing rod 57 and the connecting bar 50 is used to strengthen the stability of the pressure of the pressing block 56 on the fitting by the hydraulic telescopic cylinder six 55.

[0069] One end of the fixed rod 57 far away from the second connecting block 48 is fixedly connected with a laser scanning sensor 59. The laser scanning sensor 59 is a conventional existing technology. It irradiates a laser at the target object and receives the reflected light and the changes after refraction through a photosensitive element, so as to integrally scan the outer contour of the hoist accessories in a non-contact manner;

[0070] The laser scanning sensor 59 is signal-connected to a processor. The processor calculates the outer contour of the hoist accessories after being scanned by the laser scanning sensor 59 and constructs a three-dimensional model, and marks the specific information to be processed of the hoist accessories, including but not limited to: the position coordinates of the accessories processing, the processing method, etc.

[0071] In this embodiment, the accessories to be processed are hoisted and placed on the support plate composed of the central disk 12 and the annular support group 15. In the initial state, the fifth hydraulic telescopic cylinder 47 is in the extended state. During the hoisting process, the outer contour of the accessories is scanned by the laser scanning sensor 59, and a three-dimensional model is constructed by the processor;

[0072] The processor calculates the center point of the hoist accessories, and controls the movement of the hoist accessories through the hoisting tool, so that its center point coincides with the center point of the central disk 12. Then, according to the outer contour shape of the side of the accessories close to the turntable 6, the corresponding support blocks 16 are controlled to rise or fall, providing the maximum support area for the accessories without damaging and affecting the processing of the accessories, so as to increase the stability of the support for the accessories; Exemplarily, when drilling is required for the accessories processing, the relevant support blocks 16 at the corresponding positions of the accessories are controlled to descend, leaving a certain gap to prevent damage to the drill bit during drilling

[0073] Subsequently, the hoist accessories are placed on the support plate, and then the pump body 20 is started, and the air valve of the corresponding air hole 18 is opened, and the hoist accessories are negatively pressured through the air hole 18.

[0074] Then, the accessories are positioned and clamped. Control a corresponding number of the first sliding seats 23 to slide to the corresponding positions. The clamped positions should be the positions on the accessories that are not processed, not weak, without holes and without grooves, so as to avoid damage and deformation of the accessories during the positioning and clamping process.

[0075] Subsequently, the angle of the clamping block 38 is effectively adjusted according to the shape of the surface of the accessories clamped by the clamping assembly 28. Exemplarily, when the surface of the accessories clamped by the clamping assembly 28 is a plane, the clamping block 38 clamps at an angle perpendicular to the plane.

[0076] During the process of the clamping block 38 clamping the accessories, the pressure sensor I monitors the pressure of the clamping block 38 clamping the accessories to prevent overpressure clamping of the accessories and causing damage to the accessories.

[0077] After the clamping block 38 finishes clamping the fitting, the air valve of the air pipe controlling the corresponding air hole 18 is opened, so that the air hole 18 adsorbs the suction plate 39, thereby improving the clamping stability of the clamping block 38 for the fitting during the processing.

[0078] Then, the output end of the hydraulic telescopic cylinder five 47 is controlled to retract, so that the circular guide rail two 41 descends to a position at a corresponding height, the corresponding number of sliding seats three 42 are controlled to move to corresponding positions, and at the same time, the driving motor five 53 is respectively controlled to rotate, and the rack 51 drives the connecting bar 50 to move towards the side close to the center of the circular guide rail two 41. According to the shape of the fitting, the stroke of each connecting bar 50 is controlled to move. Subsequently, the output end of the hydraulic telescopic cylinder six 55 is controlled to extend, so that the pressing block 56 descends to complete the positioning and clamping of the fitting in the vertical direction.
