Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of roll installation, and specifically belongs to a roll bearing installation workbench. BACKGROUND

[0002] The roll is the main working component and tool for the metal to produce continuous plastic deformation on the rolling mill. It is mainly composed of roll body, roll neck and shaft head three parts, wherein the roll body is the middle part of the roll actually participating in rolling metal, having a smooth cylindrical or surface with rolling groove.

[0003] The roll neck at both ends of the roll is used for installing the bearing, so that the roll can stably rotate and roll. After the roll works for a period of time, it needs to be disassembled to polish the roll body or replace a new roll, so as to ensure the quality of the rolled product. In the prior art, after the roll is placed on the V-shaped seat, the height of the V-shaped seat is adjusted, the roll is centered with the bearings on both sides, and finally the slide table where the bearing is located is moved to center and install the bearing on the end of the roll. In order to prevent the roll from slipping axially during the installation of the bearing and damaging the surface of the roll body, a baffle abutting against the end face of the roll shoulder is arranged on both sides of the V-shaped seat, so as to limit the sliding of the roll. However, the baffle is fixedly arranged on the V-shaped seat and cannot adapt to the use of various types of rolls (for example, the roll body of the shorter roll cannot abut against the baffle, so the sliding of the roll cannot be limited), so it is necessary to design a roll bearing installation workbench capable of adjusting the position of the baffle.

[0024] The following combination Figures 1-4 The utility model is described in detail.

[0025] Example

[0026] A roller bearing mounting workbench includes a bracket 1, a support plate 4 mounted on the top of the bracket 1, a roller placement platform 20 disposed on the support plate 4, and a first V-shaped seat 2001. The bottom of the first V-shaped seat 2001 is provided with a groove 2008 along its length. A forward and reverse screw rod 2005 is rotatably disposed in the groove 2008. Two Y-shaped baffles 2004 that move relative to each other are threadedly connected to the forward and reverse screw rod 2005. A first bevel gear 2006 is fixedly mounted on the forward and reverse screw rod 2005. The first bevel gear 2006 is meshed with a second bevel gear 2007. The second bevel gear 2007 is connected to a connecting shaft 2010 that rotates through the first V-shaped seat 2001. The connecting shaft 2010 is connected to a first handwheel 2009. A lifting device 3 is connected to the bottom of the roller placement platform 20. The first V-shaped seat 2001 is used to place a roller 19.

[0027] The operator can rotate the second bevel gear 2007 via the first hand wheel 2009, causing the first bevel gear 2006 meshing with the second bevel gear 2007 to rotate simultaneously. The forward and reverse screw rods 2005 rotate synchronously with the first bevel gear 2006, which drives the two Y-shaped baffles 2004 to adjust the spacing to accommodate the use of different rollers 19. Before placing the roller 19, the spacing between the two Y-shaped baffles 2004 is adjusted according to the length of the roller body of the roller 19. After the adjustment is completed, the roller 19 is placed. After the roller 19 is placed, the two Y-shaped baffles 2004 are adjusted so that the two Y-shaped baffles 2004 clamp the shaft shoulder of the roller 19, thereby better limiting the slippage of the roller 19.

[0028] Slide rails 6 are provided on both sides of the roll placement platform 20 along the length of the first V-shaped seat 2001. A first slide 5 slides on the slide rails 6. A second V-shaped seat 18 is provided on the first slide 5. A baffle 16 is connected to the side of the second V-shaped seat 18 facing away from the roll placement platform 20. The baffle 16 has a through hole 15 and is connected to a telescopic cylinder 13 for driving the movement of the first slide 5. The second V-shaped seat 18 is used to accommodate a bearing 17.

[0029] Telescopic cylinder 13 drives first slide 5 toward roller placement platform 20, allowing bearing 17 on second V-shaped seat 18 to be aligned and inserted onto the shaft head at the end of roller 19. Baffle 16 assists in stabilizing bearing 17 and, during installation, presses bearing 17 to insert it onto roller 19. Through hole 15 is provided for the end of roller 19 to pass through, preventing baffle 16 from obstructing bearing 17 installation.

[0030] The telescopic end of the telescopic cylinder 13 is connected with a top cover 14, the top cover 14 is fixedly connected with the baffle 16 and the top cover 14 covers the through hole 15. In order to better push the bearing 17, the telescopic cylinder 13 needs to be arranged at the shaft center of the through hole 15, and in order to ensure that the end of the roller 19 can normally pass through the through hole 15, a top cover 14 needs to be arranged to avoid.

[0031] The end of the telescopic cylinder 13 away from the baffle 16 is fixedly connected with a vertical plate 12, the lower end of the vertical plate 12 is connected with a second sliding table 9 matched with the slide rail 6, the second sliding table 9 vertically movably penetrates a screw rod 10, and a plurality of threaded insertion holes 8 matched with the screw rod 10 are arranged on the support plate 4 along the length direction of the slide rail 6.

[0032] The second sliding table 9 can adjust the position of the telescopic cylinder 13, and the locking of the second sliding table 9 is realized by screwing the screw rod 10 into the threaded insertion hole 8. The telescopic cylinder 13 can adjust the position according to the requirement, so as to adapt to different installation conditions, for example, the overall length of part of the roller 19 is relatively short, the telescopic cylinder 13 cannot extrude the bearing 17 to the accurate position, so after adjusting the position of the telescopic cylinder 13, the telescopic cylinder 13 can be ensured to be installed to the specified position after being elongated.

[0033] The side of the vertical plate 12 away from the telescopic cylinder 13 is provided with a reinforcing support plate 11 connected with the second sliding table 9. The reinforcing support plate 11 strengthens the connection strength of the vertical plate 12, so as to avoid the deformation of the vertical plate 12 due to the extrusion reaction force of the telescopic cylinder 13.

[0034] The lifting device 3 comprises a gear reversing box 301, one output end of the gear reversing box 301 is connected with a vertical stud 303, the bottom of the first V-shaped seat 2001 is connected with a square plug 2002, the bottom of the square plug 2002 is provided with a screw hole 2003 matched with the stud 303, the support plate 4 is provided with a square hole 7 matched with the square plug 2002, and the other output end of the gear reversing box 301 is connected with a second hand wheel 302.

[0035] The square plug 2002 is driven to rotate by the square hole 7, and the square plug 2002 is driven to vertically move by the square hole 7. The first V-shaped seat 2001 is driven to vertically move by the screw post 303 and the screw hole 2003, and the first V-shaped seat 2001 is driven to vertically move by the square hole 7. The height of the roller 19 can be adjusted by the first V-shaped seat 2001, so that the roller 19 can be conveniently centered according to the size of the bearing 17. The mounting plate 2 is arranged between the supports 1 and is used for mounting the gear reversing box 301. The gear reversing box 301 is provided with a pair of meshing bevel gears. The output shaft of one bevel gear is connected with the screw post 303, and the output shaft of the other bevel gear is connected with the second hand wheel 302.

[0036] In order to avoid the impurities from gathering in the groove 2008 and affecting the rotation of the positive and negative screw rods 2005, the groove 2008 is arranged as a through groove, and the impurities can directly fall on the support plate 4.

[0037] The above is only the preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
