Description

Technical Field

[0001] The utility model belongs to the field of hole-opening auxiliary devices, and particularly relates to a bucket seat hole-opening auxiliary device. Background Technique

[0002] The bucket seat is a key component connecting the bucket part of the excavator and the fuselage. It ensures that the bucket teeth can be firmly installed on the excavator fuselage, providing a solid foundation for the excavation operation of the bucket teeth. The firm connection of the bucket seat enables the excavator to remain stable under complex working conditions, thus ensuring the safety and continuity of the excavation operation; according to the different sizes of the bucket teeth equipped with different buckets, the sizes of the bucket seats for installing the bucket teeth are also different. The connection part of the bucket seat mainly relies on the holes on it. When producing the bucket seat, the hole positions of the small bucket seats are directly processed by a stamping machine. However, when stamping the hole positions of the medium and large bucket seats, it is easy to cause extrusion deformation, resulting in the overall deformation of the bucket seat. Only after the bucket seat cools down can it be processed by a drilling machine or a milling machine; and both of these processing devices require auxiliary jigs for positioning drilling, which leads to a very large workload for one person to operate multiple machines in a continuous rotation. Moreover, the large bucket seats weigh more than 10 kg, and it is extremely easy to injure the waist or legs when employees work in a hurry and chaos. Content of the Utility Model

[0020] Embodiment 1

[0021] As Figure 1 shown; A bucket seat hole-opening auxiliary device includes a fixed frame 1, a hole-opening auxiliary device 2 and a drilling machine. A plurality of the hole-opening auxiliary devices 2 are installed on the fixed frame 1, and a plurality of the drilling machines are installed on the fixed frame 1 and cooperate with the hole-opening auxiliary devices 2; The hole-opening auxiliary device 2 includes a positioning mechanism 3 and a clamping mechanism 4. The positioning mechanism 3 and the clamping mechanism 4 are both connected to the fixed frame 1, and the clamping mechanism 4 cooperates with the positioning mechanism 3; The positioning mechanism 3 includes a C-shaped clamping and positioning seat 31, a fixed clamping plate 32, a movable clamping plate 33, an adjusting plate 34 and a locking bolt 35. The C-shaped clamping and positioning seat 31 is connected to the fixed frame 1. One end inner side of the C-shaped clamping and positioning seat 31 is connected with a plurality of fixed clamping plates 32. A plurality of the movable clamping plates 33 are connected to the adjusting plate 34 and cooperate with the fixed clamping plates 32 to clamp the bucket seat. The locking bolt 35 penetrates through the other end of the C-shaped clamping and positioning seat 31 and is movably connected to the adjusting plate 34. The fixed clamping plates 32 and the movable clamping plates 33 are arranged alternately; The clamping mechanism 4 includes a fixed seat 41, a locking oil cylinder 42, a slide plate 43, a positioning frame 44, a cylinder fixing frame 46, a pushing and clamping oil cylinder 47, a replacement positioning plate 48 and a clamping top strip 49. Two of the fixed seats 41 are connected to the fixed frame 1 and are located on both sides of the C-shaped clamping and positioning seat 31. Two of the locking oil cylinders 42 are connected to the corresponding fixed seats 41 and the piston rods are both connected to the slide plate 43. Both ends of the slide plate 43 are slidably connected to the corresponding fixed seats 41. Two of the positioning frames 44 are symmetrically connected to the slide plate 43 and are used for stacking and positioning of the bucket seat. The pushing and clamping oil cylinder 47 is connected to the slide plate 43 through the cylinder fixing frame 46 and the piston rod penetrates through the replacement positioning plate 48 and is connected to the clamping top strip 49. The replacement positioning plate 48 is connected to the cylinder fixing frame 46 and is used for positioning of the bucket seat; A discharge hopper 36 is connected to the C-shaped clamping and positioning seat 31; A plurality of limiting strips 45 are connected to the positioning frame 44; A plurality of screw holes for connecting the positioning frame 44 are opened on the slide plate 43; A chip removal hole is opened on the fixed frame 1 below between the fixed clamping plate 32 and the movable clamping plate 33.

[0022] Previously, the stacked bucket seats are lifted by the overhead crane to between the two positioning frames 44, and the stacked bucket seats are limited by the limiting strips 45 on the two positioning frames 44. Then, adjust the locking bolt 35 to drive the moving clamping plate 33 to move by the adjusting plate 34. It mainly adjusts the distance between the moving clamping plate 33 and the fixed clamping plate 32 according to the head condition of the bucket seat, which is convenient for installing various bucket seats. Since the sizes between the head and the tail of the bucket seat are different, positioning interference will occur without adjustment. The bucket seat closest to the slide plate 43 is not restricted by the limiting strip 45 in the direction close to the C-shaped clamping and positioning seat 31, so that the bucket seat can be pushed towards the C-shaped clamping and positioning seat 31; drive the clamping top bar 49 to move by the pushing and clamping oil cylinder 47, and the bucket seat closest to the slide plate 43 is pushed towards the C-shaped clamping and positioning seat 31. At the same time, the bucket seat is pushed until its head is against the moving clamping plate 33 and the fixed clamping plate 32. The verticality of the hole opening of the bucket seat is ensured by positioning the head of the bucket seat with several moving clamping plates 33 and the fixed clamping plate 32. After the bucket seat is pushed out, the upper stacked bucket seats are supported by the clamping top bar 49. Then, the drilling machine drills the bucket seat. After the bucket seat is drilled, the pushing and clamping oil cylinder 47 drives the clamping top bar 49 to move a little further, so that the bucket seat moves out of the bucket seat stacking area. Then, the locking oil cylinder 42 drives the slide plate 43 to move away from the C-shaped clamping and positioning seat 31, so that the bucket seat falls on the export bucket 36 and slides out. Finally, the locking oil cylinder 42 drives the slide plate 43 to reset, and the hole positions of the bucket seats are processed in this cycle; adjust the distance between the two positioning frames 44 according to the size of the bucket seat; the iron shavings generated by drilling fall and are exported through the chip removal hole.
