Problems solved by technology

[0003] Moreover, excavators mostly work in the field, and the conditions for replacing bushings on site cannot be guaranteed.
In order to shorten the replacement time, some operators weld the processing device on the bucket for processing, or heat the bucket to cause thermal expansion and deformation, and then take out the bushing by knocking, which will have a negative impact on the shape, size and metallographic structure of the bucket. Adverse effects, reduced bucket life
If the bucket is disassembled and transported to the workshop for processing, the maintenance time will be greatly increased
Moreover, the machine tool needs to be positioned and clamped by the shape of the bucket. Due to the complex deformation of the bucket during use, the positioning accuracy and the machining accuracy of the shaft hole cannot be guaranteed, thereby reducing the processing efficiency and economic benefits of the bucket shaft hole.

Embodiment 1

[0065] See Figure 1-3 A field processing apparatus for excavator bucket shaft holes, including positioning processing mechanisms and locking mechanisms including positioning shafts 8, bearings 11, motor 7, boring knife 10 and for positioning shaft holes 30 center The positioning sleeve 9, the positioning shaft 8 penetrating the shaft hole 30, the positioning shaft 8 is connected to the motor 7, and the other end is connected to the bearing 11, the bearing 11 is mounted on the boring arm 27 through the casing 12, said The positioning sleeve 9 is arranged on the positioning shaft 8 and placed in the shaft hole 30, and the positioning shaft 8 is provided with a step portion that is fitted with the positioning sleeve 9, and the outer surface of the positioning sleeve 9 is provided with a taper. Motor 7 external generator, the locking mechanism locks the processing device to the bucket body 5, and replaces the positioning sleeve 9 to achieve the boring processing of the axis hole 30.

...

Embodiment 2

[0074] See Figure 1 - Figure 3 When machining the lower boring of the first set of shaft holes 30, a processing method of a field processing apparatus of an excavator tutoring shaft hole as described in Example 1, comprising the steps of: assembling a processing device, positioning processing Device, locking processing means, replacing the boring knife and the boring processing step.

[0075] Preferably, the steps of:

[0076] Step S1, assemble the processing device, the specific steps are as follows:

[0077] S11, assemble the base 17, placed the inner sleeve 22, the outer casing 23 on the bucket main body 5, and the left ferric 13 is fixed to the inner sleeve 22, and the base 17 is assembled with the side plate 15 with bolts. ;

[0078] S12, assemble the right trick 24, adjust the position of the right base 17 and the bucket main body 5 to ensure that there is a 5 mm gap, and the right tric wattle 24 is welded to the outer casing 23;

[0079] S13, assemble the cylinder 4, mount ...

Embodiment 3

[0110] A 20-ton excavator works in the wild, after four months of the sediment environment, the bushing of the bucket main body 5, the pin and the shaft hole 30 wear is serious, and the site is required. The field processing apparatus of the excavator bucket shaft hole according to Example 1 was operated by the transport vehicle to the site, and the on-site machining and bushing replacement of the shaft hole 30 was carried by the carrier and the engine. First, the excavator lifts the bucket to the transport vehicle and removes the bucket from the excavator and placed on the transport vehicle. Adjust the roof position, follow image 3 As shown, the above-mentioned shaft hole 30 is based on the machining method of Example 2, and the positioning shaft 8 and the positioning sleeve 9 are positioned, and the side surface of the bucket body 5 is clamped. Connect the hydraulic pump and the engine while machining the shaft holes 30 on the upper surface of the bucket body 5. The lower shaft ...

Abstract

The invention discloses an on-site machining device for a shaft hole of an excavator bucket. The on-site machining device comprises a positioning machining mechanism and a locking mechanism, the positioning machining mechanism comprises a positioning shaft, a bearing, a motor, a boring cutter and a positioning sleeve used for positioning the center of the shaft hole, the positioning shaft penetrates through the shaft hole, one end of the positioning shaft is connected with the motor, and the other end of the positioning shaft is connected with the bearing; and the bearing is installed on a boring arm through a clamping base, the positioning sleeve is arranged on the positioning shaft and placed in the shaft hole, and the positioning shaft is provided with a step part matched with the positioning sleeve. The machining device is locked to an excavator bucket body through a hydraulic mechanism and the boring arm, boring machining of the shaft hole is achieved by replacing the positioning sleeve with the boring cutter, and rapid clamping and locking are achieved through a pipe-in-pipe structure and a sleeve-in-sleeve structure. The invention further discloses an on-site machining method for the shaft hole of the excavator bucket. According to the on-site machining device for the shaft hole of the excavator bucket and the method, the consistency of positioning and machining is guaranteed, and the machining precision of the shaft hole is improved.

Description

Technical field [0001] The present invention relates to the daily maintenance of construction machinery, and more particularly to the field processing apparatus of excavator harbing shaft holes and its processing methods. Background technique [0002] The bucket refers to a bucket member for excavating soil, Huangsha, stone and construction waste, which is mounted on an excavator for excavating. However, the excavator works more in the sediment environment, and the four shaft hole lubs on the bucket hanging ear is extremely easy to contaminate. After the hard particles enter the shaft hole, the shaft, the bushing is in the abrasive particle wear, accelerate the shaft , The wear of the bushing and the shaft hole needs to be repaired in time. Since wear and deformation occurs due to the shaft hole, the boring processing needs to be performed before the replacement of the excavated bushing. [0003] Moreover, the excavator is more in the field, and the conditions for replacement bus...
