Detailed Implementation

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0033] Example:

[0034] A bearing housing grinding and polishing equipment, such as Figure 1 As shown, it includes: a housing 1, a grinding tool changing device 5, and a control device; a fixing device 2 is installed at the lower end of the housing 1; the fixing device 2 is used to fix the bearing housing; a moving device 3 is installed at the upper end of the housing 1 corresponding to the fixing device 2; a grinding and polishing device 4 is installed at the lower end of the moving device 3; the moving device 3 drives the grinding and polishing device 4 to perform grinding and polishing treatment on the bearing housing; the grinding tool changing device 5 is installed on one side of the grinding and polishing device 4 and is used to replace the grinding tools on the grinding and polishing device 4; the control device is used to control the operation of the entire bearing housing grinding and polishing equipment except for itself.

[0035] Specifically, such as Figure 2-4 As shown, the fixing device 2 includes: two reciprocating threaded screws 201, a clamping plate 202, and a motor 204; the two reciprocating threaded screws 201 are symmetrically rotated and mounted on the lower end face of the housing 1, and are connected by a belt 203; the output end of the motor 204 is fixedly connected to one of the reciprocating threaded screws 201; the clamping plate 202 is composed of two symmetrical semicircular plates; the reciprocating threaded screws 201 are divided into reciprocating threads from the middle position; two semicircular plates are symmetrically slidably mounted on each reciprocating threaded screw 201, and each of the two semicircular plates is connected to one of the threads, and the two semicircular plates move under the rotation of the reciprocating threaded screws 201 to achieve clamping and loosening of the bearing housing; the clamping plates 202 on the two reciprocating threaded screws 201 are symmetrically arranged to jointly fix the bearing housing;

[0036] The operator places the unpolished bearing housing between two clamping plates 202. The motor 204 starts, driving the two forward and reverse screws 201 to rotate, which in turn drives each semicircular plate to move towards each other, thereby fixing the front and rear ends of the bearing housing through the two clamping plates 202.

[0037] Specifically, such as Figure 5-7As shown, the mobile device 3 includes: a mounting frame 301; the mounting frame 301 is fixedly mounted on the upper end of the housing 1; a fixed frame 303 is slidably mounted on both the front and rear ends of the mounting frame 301, and is driven by two electric telescopic frames 302 fixedly mounted on the mounting frame 301 respectively; the two fixed frames 303 are symmetrically arranged.

[0038] Each fixed frame 303 is equipped with an electric lead screw device 304, which is placed horizontally. A slider is slidably mounted on the electric lead screw device 304. An electric cylinder 305 is vertically fixed on the slider, with its output end pointing vertically downwards. A grinding and polishing device 4 is fixedly connected to the output end of the electric cylinder 305. When the electric telescopic frame 302 is activated, it can drive the grinding and polishing device 4 to move back and forth. When the electric lead screw device 304 is activated, it can drive the grinding and polishing device 4 to move left and right. When the electric cylinder 305 is activated, it can drive the grinding and polishing device 4 to move up and down. The electric cylinder 305 is a servo electric cylinder. The moving device 3 drives the two grinding and polishing devices 4 to grind the bearing box simultaneously, thereby improving the grinding efficiency of the bearing box.

[0039] Specifically, such as Figure 7-16 As shown, the polishing device 4 includes: a second mounting frame 401, a second belt 402, a rotating disk 404, and polishing tools; the upper end of the second mounting frame 401 is fixedly connected to the output end of the first electric cylinder 305; a rotating shaft 406 is rotatably mounted on the second mounting frame 401; the rotating shaft 406 is connected to the output end of the second motor 403 fixedly mounted on the second mounting frame 401 via the second belt 402; a hexagonal groove is provided on the lower end face of the rotating shaft 406.

[0040] The rotating disk 404 is rotatably mounted on the mounting bracket 401 and located below the mounting bracket 401, and is driven by the motor 405 fixedly mounted on the mounting bracket 401. The rotating disk 404 is symmetrically provided with two mounting holes for mounting grinding tools. The rotating disk 404 is provided with an automatic locking mechanism corresponding to the mounting holes. The automatic locking mechanism is used to fix the grinding tools on the rotating disk 404. The mounting holes correspond intermittently with the hexagonal groove below the rotating shaft 406 during the rotation of the rotating disk 404.

[0041] As a specific implementation method of this embodiment, such as Figure 9 and 11 As shown in Figure 13, the automatic locking mechanism includes: a locking plate 407 and a compression spring 408; the two locking plates 407 are symmetrically and elastically slidably mounted on the rotating disk 404 through the compression spring 408; the grinding tool is placed in the mounting hole and fixed by the automatic locking mechanism; the front end of the locking plate 407 is pointed, which makes it easy to push the locking plate 407 to move left and right.

[0042] Specifically, such as Figure 9 and 15 As shown in Figure -16, the grinding tool includes a grinding unit and a polishing unit; the grinding unit includes a collar 409, a grinding rod 410, and a compression spring 411; the upper end of the grinding rod 410 is provided with an external hexagonal protrusion that corresponds to the hexagonal groove at the lower end of the rotating shaft 406; the upper end of the grinding rod 410 is slidably and rotatably installed in the collar 409, and is elastically connected to the collar 409 through the compression spring 411; the upper end of the compression spring 411 is fixedly connected to the grinding rod 410, and the lower end abuts against the inner side of the collar 409;

[0043] The only difference between the polishing unit and the grinding unit is that the grinding rod 410 is replaced with a polishing rod. The upper end of the polishing rod is provided with an external hexagonal protrusion that corresponds to the hexagonal groove at the lower end of the rotating shaft 406. The upper end of the polishing rod is slidably and rotatably installed in the collar 409 and is elastically connected to the collar 409 through a compression spring 411. The upper end of the compression spring 411 is fixedly connected to the polishing rod, and the lower end abuts against the inner side of the collar 409. The collar 409 is intermittently fixed in the mounting hole 1 of the rotating disk 404. When the grinding tool changing device 5 sends the grinding tool into the mounting hole 1 on the rotating disk 404, the clamping plate 407 squeezes the collar 409 under the action of the compression spring 408, fixing the collar 409 in the mounting hole 1. The outer side of the collar 409 is provided with an annular groove that matches the mounting hole 1, which prevents the collar 409 from sliding up and down in the mounting hole 1, making it easier for the clamping plate 407 to fix the collar 409.

[0044] When grinding the bearing housing, the grinding tool changing device 5 feeds the required grinding tool into the mounting hole one, and the collar 409 is fixed in the mounting hole one by the clamping plate 407; the motor three 405 starts, driving the rotating disk 404 to rotate, the rotating disk 404 drives the collar 409 to rotate, and in turn drives the grinding rod 410 to rotate; during the rotation of the grinding rod 410, it abuts against the bottom end of the mounting bracket two 401, the grinding rod 410 moves downward, and the compression spring two 411 is compressed; when the rotating disk 404 rotates to the designated position, the mounting hole one corresponds to the hexagonal groove on the rotating shaft 406. Under the action of the compression spring 411, the grinding rod 410 moves upward, and the hexagonal protrusion at the upper end of the grinding rod 410 is inserted into the hexagonal groove on the rotating shaft 406; the rotating shaft 406 is driven to rotate by the motor 403, which in turn drives the grinding rod 410 to rotate; the moving device 3 starts, driving the grinding rod 410 to move along the axial direction inside the housing to grind the bearing housing; similarly, when the bearing housing needs to be polished, the grinding tool changing device 5 sends the polishing rod into the mounting hole 1, and repeats the above operation, with the moving device 3 driving the polishing rod to polish the bearing housing.

[0045] Specifically, such as Figure 5-6As shown in Figures 17-18, the two grinding tool changing devices 5 are respectively fixedly installed on the mounting frame 301 corresponding to the two grinding and polishing devices 4.

The lower end of mounting block 502 is rotatably mounted with mounting plate 2 505. The mounting plate 2 505 is provided with a connecting shaft in the middle for mounting... Plate 2 is rotatably mounted on mounting block 502 via a connecting shaft; Gear 1 (not shown in the figure) is fixedly mounted on the connecting shaft; Motor 4 504 is fixedly mounted on the lower end face of mounting block 502, and Gear 2 (not shown in the figure) is fixedly connected to the output end of motor 4 504; Gear 1 and Gear 2 mesh with each other; Mounting plate 2 505 is driven to rotate by motor 4 504; At the same time, in order to prevent dust from falling into motor 4 504 during grinding and polishing, a protective cover is provided at the lower end of mounting block 502, and motor 4 504, gear 1 and gear 2 are all located inside the protective cover;

[0046] Mounting plate 2 505 has six mounting holes 2, and an automatic locking mechanism 2 is provided at the corresponding position of each mounting hole 2; the automatic locking mechanism 2 has the same structure and working principle as the automatic locking mechanism 1; three mounting holes 2 are equipped with grinding tools for grinding the bearing housing, and the grinding rods 410 on the three grinding tools are of different shapes; the other three mounting holes 2 are equipped with grinding tools for polishing the bearing housing, and the polishing rods on the three grinding tools are of different shapes; by changing the grinding rods 410 or polishing rods of different shapes, different structures inside the bearing housing can be ground or polished;

On 507; the electric cylinder 3 506 drives the semi-annular electromagnet 507 to continue moving, causing the collar 409 to push open the automatic locking mechanism 2, and then push open the automatic locking mechanism 1 on the rotating disk 404, sending the grinding tool into the mounting hole 1 on the rotating disk 404. The automatic locking mechanism 1 fixes the grinding tool on the rotating disk 404; the semi-annular electromagnet 507 is de-energized, and the electric cylinder 3 506 drives the semi-annular electromagnet 507 to reset; the grinding and polishing device 4 and the moving device 3 cooperate to drive the grinding tool to grind or polish the bearing box;

[0049] When the polishing tool on the polishing device 4 needs to be replaced, motor 3 405 starts, driving the rotating disk 404 to rotate, so that the mounting hole 1 on the rotating disk 404 moves to the position corresponding to the polishing tool replacement device 5; motor 4 504 starts, driving the mounting plate 2 505 to rotate, so that the mounting hole 2 of the polishing tool originally placed on the rotating disk 404 rotates to the position corresponding to the rotating disk 404; the semi-annular electromagnet is energized, and the electric cylinder 3 506 drives the semi-annular electromagnet 507 to move, moving the polishing tool on the rotating disk 404 to the mounting plate 2 505; the automatic locking mechanism 2 on the mounting plate 2 505 fixes the polishing tool.
