Problems solved by technology

[0003] The scraping method is usually manually scraped with a triangular scraper, a flat scraper or a snake head scraper. Scraping is a compulsory course for fitters. Manual scraping and maintenance takes a long time, the efficiency is low, and the technical level of the operators is different, resulting in large temperature differences between the bearings. Poor maintenance effect, etc.

Embodiment 1

[0038] Such as Figure 1-5 As shown, an electromechanical scraping device of the present invention includes a scraping shoe base 1, a lifting pillar 2, a bearing pad clamping platform 3 and a hob shaft 4. The tile base 1 is used to support the entire scraping device, and the scraping shoe base The four corners of 1 are provided with elevating motors 5 respectively, and each elevating motor 5 is connected with elevating struts 2, and the upper end of said elevating struts 2 is provided with elevating sleeves 7, and elevating sleeves 7 can rotate on elevating struts 2, because there are The lifting shaft of the table lifting motor 5 is rotated to raise or lower, and the four lifting sleeves 7 are connected end to end by two transverse bars 8 and two longitudinal bars 9 to form a square frame structure. The two transverse bars 8 are symmetrically arranged in parallel, Two longitudinal rods 9 are symmetrically arranged in parallel, two horizontal rods 8 and two longitudinal rods 9...

Embodiment 2

[0056] Such as Figure 1-5 Shown, a kind of electromechanical scraping tile method of the present invention comprises steps:

[0057] Step 1 Place the bearing bush 17 on the clamping table 20, and set the two ends of the bearing bush 17 corresponding to the sliding clamp block 21, and firmly clamp the bearing bush 17 by turning the hand wheel or the hand wheel motor 23, and control the rotation of the clamping table rotating motor 19 The end face of the bearing bush 17 is set at an angle of 45° with the hob shaft 4;

[0058] Step 2 Install the matching hob 18 on the hob shaft 4 according to the model of the bearing bush 17, then start the moving motor 11 and the lifting motor 5 to drive the hob 18 and the scraping arc surface of the bearing bush 17 to perform knife alignment, and determine the scraping tile through the knife alignment The three-dimensional coordinates of the arc bottom and the upper arc edge of the arc surface, so as to determine the spatial position of the s...

Abstract

The invention discloses an electric mechanical bearing bush grinding device and a bearing bush grinding method. According to the electric mechanical bearing bush grinding device, the four corners of abearing bush grinding base are correspondingly provided with lifting motors, each lifting motor is connected with a lifting supporting column, and lifting sleeves are arranged at the upper ends of the lifting supporting columns; the four lifting sleeves are connected end to end through two transverse rods and two longitudinal rods to form a square frame structure, longitudinal moving blocks are correspondingly arranged on the two longitudinal rods in a sleeving mode, the two longitudinal moving blocks are correspondingly provided with moving motors, and the two moving motors synchronously drive the two longitudinal moving blocks to move left and right on the longitudinal rods; the lower portions of the longitudinal moving blocks are correspondingly connected with lifting rods, a hobbing cutter shaft is installed at one ends of the two lifting rods through a rotating seat, and a hobbing cutter shaft gear is arranged at one end of the hobbing cutter shaft; a hobbing cutter shaft motor is arranged on one of the longitudinal moving blocks, a rotating shaft gear is arranged on a rotating shaft of the hobbing cutter shaft motor, and the rotating shaft gear is in transmission connectionwith the hobbing cutter shaft gear through a chain; and a bearing bush clamping table is arranged in the middle of the bearing bush grinding base and is used for clamping a bearing bush, and the hobbing shaft is provided with a hobbing cutter for performing grinding on the bearing bush.

Description

technical field [0001] The invention relates to the technical field of grinding and scraping applied to hydropower station sliding bearings (alloy sliding bearings), in particular to an electromechanical shoe scraping device and a shoe scraping method. A time-saving and labor-saving scraping mechanical tool is provided for the maintenance of sliding bearings in hydropower stations. Background technique [0002] Sliding bearings (alloy sliding bearings) of hydroelectric generator sets generally need to be ground and scraped. The purpose of grinding and scraping the bearing pad is to make the pad surface into a circular arc geometry. There is a wedge-shaped gap between the bearing bush and the shaft strength to ensure that when the shaft rotates, a wedge-shaped oil film can be formed between the friction surfaces, so that the shaft diameter is separated from the pad surface and operates under the buoyancy of the oil film to reduce friction with the tile surface. There is a w...
