Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing technology, and in particular to a bearing manufacturing end face grinding device. Background Technology

[0002] In the bearing manufacturing process, the inner and outer rings of the bearing are usually obtained by cutting steel pipes to a fixed length, followed by precision machining and heat treatment. The two cut end faces of the bearing rings need to be ground. Grinding can improve the flatness and perpendicularity of the end faces, ensure proper alignment during bearing installation, reduce friction and wear during operation, remove manufacturing defects, improve surface quality, thereby extending the bearing's service life and improving overall performance. Existing bearing end face grinding equipment can basically meet daily usage needs, but there are still some shortcomings that need to be improved.

[0003] Traditional bearing ring end face grinding processes typically involve placing the bearing rings in a circular grinding platform. This platform can only hold a limited number of bearing rings of the same diameter at a time, and the finished products cannot be removed before the machine stops. This results in inconsistent and continuous processing, low grinding efficiency, and inconvenient handling, further impacting overall efficiency. To address these issues, we propose a bearing production end face grinding device. Utility Model Content

[0004] The purpose of this invention is to provide a bearing manufacturing end face grinding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bearing end face grinding device, comprising a processing table, a base plate installed at the bottom of the processing table, a guide column installed at the rear end of the top of the processing table, a grinding machine installed inside the guide column via a lifting assembly, a grinding disc installed at the bottom of the grinding machine, a rotating base rotatably connected to the front side of the top of the processing table, multiple sets of mounting platforms installed at equal intervals outside the rotating base, each mounting platform having a positioning pin installed at its top, a bearing sleeve provided outside each positioning pin, a positioning hole adapted to the positioning pin being opened at the bottom of each bearing sleeve, a connecting ring connecting the multiple sets of bearing sleeves, both sides of the rotating base being connected to the bearing sleeves via locking assemblies, a driven gear connected to the bottom of the rotating base via a rotating shaft, a first motor installed at the bottom of the processing table, a driving gear installed at the output end of the first motor, and the driven gear meshing with the driving gear.

[0006] As an improved technical solution, the lifting assembly includes a movable inner cavity formed inside the guide column, a lead screw rotatably connected inside the movable inner cavity, a threaded sleeve threadedly connected to the outside of the lead screw, guide grooves formed on both the front and rear sides of the movable inner cavity, guide plates installed on both the front and rear outer walls of the threaded sleeve, and a second motor installed at the top of the guide column, with the output end of the second motor connected to the top of the lead screw.

[0007] As an improved technical solution, the locking assembly includes slide blocks fixed on both sides of the rotating base. Slip rings are slidably connected in both sets of slide blocks. Locking rods are fixed inside the slip rings. Handles are installed at opposite ends of both sets of locking rods. Locking cylinders are installed on the outer walls of opposite ends of both sets of bearing sleeves. Opposite ends of both sets of locking rods are embedded in the two sets of locking cylinders. Return springs are wound around the outside of both sets of locking rods.

[0008] As an improved technical solution, the grinding machine is equipped with a control panel, and the input terminals of the first motor and the second motor are electrically connected to the control panel through wires.

[0009] As an improved technical solution, the outer surface of the interlocking rings is provided with anti-slip rubber sleeves.

[0010] As an improved technical solution, the two ends of the return spring are respectively connected to the outer wall of the slip ring and the inner wall of the slide block, and the slip ring is elastically connected to the inside of the slide block through the return spring.

[0011] As an improved technical solution, the outer wall of the slip ring is fully fitted with the inner wall of the slide block.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are:

[0013] I. This utility model features a rotatable base mounted on a processing table, with multiple mounting platforms on the base. Multiple sets of bearing sleeves, linked together, are mounted on these platforms. Positioning holes at the bottom of the bearing sleeves are inserted into positioning pins on the mounting platforms, quickly positioning the bearing sleeves and placing the bearings inside. A first motor drives a drive gear, which in turn drives a driven gear to intermittently rotate a shaft and the base. This causes the bearings to be ground on the sleeves to sequentially enter below a grinding disc, allowing the grinding disc to precisely grind the bearings within the sleeves. Once the ground bearings are moved to the front of the processing table by the rotating base, they can be removed from the sleeves, enabling continuous production and improving equipment processing efficiency.

[0014] II. This utility model features sliding blocks installed on both sides of a rotating base, with movable locking rods installed inside the sliding blocks. When it is necessary to replace the bearing sleeve, two sets of handles can be pulled in opposite directions, causing the two sets of locking rods to move the two sets of slip rings in opposite directions along the sliding blocks. When the ends of both sets of locking rods leave the locking cylinders on the bearing sleeves, multiple sets of bearing sleeves can be quickly removed from the mounting table and replaced with bearing sleeves of the corresponding size. This facilitates quick disassembly and assembly of bearing sleeves and adapts to the production needs of bearings of different specifications. Attached Figure Description

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] This utility model provides a technical solution: such as Figures 1 to 7As shown in this embodiment, a bearing production end face grinding device includes a processing table 1, a base plate 2 installed at the bottom of the processing table 1, a guide column 3 installed at the rear end of the top of the processing table 1, a grinding machine 4 installed inside the guide column 3 via a lifting assembly, a grinding disc 5 installed at the bottom of the grinding machine 4, a rotating base 6 rotatably connected to the front side of the top of the processing table 1, multiple sets of mounting platforms 7 are installed at equal intervals on the outside of the rotating base 6, each mounting platform 7 has a positioning pin 8 installed at the top, each positioning pin 8 has a bearing sleeve 9 installed on the outside, each bearing sleeve 9 has a positioning hole 10 at the bottom end that matches the positioning pin 8, multiple sets of bearing sleeves 9 are connected by a link 11, both sides of the rotating base 6 are connected to the bearing sleeves 9 via a locking assembly, the bottom of the rotating base 6 is connected to a driven gear 14 via a rotating shaft 13, a first motor 15 is installed at the bottom of the processing table 1, a driving gear 16 is installed at the output end of the first motor 15, and the driven gear 14 and the driving gear 16 mesh with each other.

[0025] By installing a rotatable rotating base 6 on the processing table 1, and multiple sets of mounting platforms 7 on the rotating base 6, and multiple sets of bearing sleeves 9 connected together by a linkage 11 on the multiple sets of mounting platforms 7, the positioning holes 10 at the bottom of the multiple sets of bearing sleeves 9 are inserted into the multiple sets of positioning pins 8 on the mounting platforms 7, and the bearing sleeves 9 are quickly positioned. The bearings can then be placed in the bearing sleeves 9. Then, the first motor 15 drives the drive gear 16 to rotate, which in turn drives the driven gear 14 to drive the rotating shaft 13 and the rotating base 6 to rotate intermittently. This causes the bearings to be ground on the bearing sleeves 9 to enter the underside of the grinding disc 5 in sequence, allowing the grinding disc 5 to precisely grind the bearings in the bearing sleeves 9. When the ground bearings are moved to the front end of the processing table 1 by the rotating base 6, the ground bearings in the bearing sleeves 9 can be removed, thereby achieving non-stop production and improving the processing efficiency of the equipment.

[0026] In other embodiments, the lifting assembly includes a movable inner cavity 17 formed in the guide column 3, a lead screw 18 rotatably connected in the movable inner cavity 17, a threaded sleeve 19 threadedly connected to the outside of the lead screw 18, guide grooves 20 formed on both the front and rear sides of the movable inner cavity 17, guide plates 21 installed on both the front and rear outer walls of the threaded sleeve 19, and a second motor 22 installed at the top of the guide column 3, with the output end of the second motor 22 connected to the top of the lead screw 18.

[0027] By installing a lead screw 18 inside the guide column 3, the second motor 22 drives the lead screw 18 to rotate, which allows the threaded sleeve 19 to move vertically under the action of the thread and the guide groove 20. This allows the guide plate 21 to drive the grinding machine 4 and the grinding disc 5 to perform precise lifting and lowering, thereby improving the vertical feed accuracy of the grinding disc 5 and enhancing the flatness of the end face.

[0028] In other embodiments, the locking assembly includes slide blocks 23 fixed on both sides of the rotating base 6, with slide rings 24 slidably connected in both slide blocks 23, and locking rods 25 fixed inside each slide ring 24. A handle 26 is installed at the opposite end of each of the two sets of locking rods 25, and locking cylinders 12 are installed on the outer wall of the opposite end of each of the two sets of bearing sleeves 9. The opposite ends of each of the two sets of locking rods 25 are embedded in the two sets of locking cylinders 12, and a return spring 27 is wound around the outside of each of the two sets of locking rods 25.

[0029] By installing slide blocks 23 on both sides of the rotating base 6 and installing movable locking rods 25 inside the slide blocks 23, when the bearing sleeve 9 needs to be replaced, the two sets of handles 26 can be pulled in opposite directions, causing the two sets of locking rods 25 to drive the two sets of slip rings 24 to move in opposite directions along the slide blocks 23, and causing the two sets of slip rings 24 to squeeze the two sets of return springs 27. When the ends of the two sets of locking rods 25 leave the inside of the locking cylinder 12 on the bearing sleeve 9, multiple sets of bearing sleeves 9 can be quickly removed from the mounting table 7 and the bearing sleeves 9 of the corresponding size can be quickly replaced. Then, the pulling force on the two sets of handles 26 is released, allowing the two sets of return springs 27 to release their elasticity and push the mass locking rods 25 to move in opposite directions, so that the ends of the two sets of locking rods 25 are inserted into the locking cylinder 12 on the replaced bearing sleeve 9, thereby facilitating the quick disassembly and assembly of the bearing sleeve 9 and adapting to the production needs of bearings of different specifications.

[0030] In other embodiments, the grinding machine 4 is provided with a control panel, and the input terminals of the first motor 15 and the second motor 22 are both electrically connected to the control panel through wires;

[0031] This design allows the control panel to precisely control the start and stop of the first motor 15 and the second motor 22, thereby ensuring that the first motor 15 and the second motor 22 can be used normally.

[0032] In other embodiments, the outer side of the chain 11 is provided with an anti-slip rubber sleeve;

[0033] This design effectively increases the friction between the chain 11 and the user's hand, making it easier to pick up and put down the chain 11 by hand.

[0034] In other embodiments, the two ends of the return spring 27 are respectively connected to the outer wall of the slip ring 24 and the inner wall of the slide block 23, and the slip ring 24 is elastically connected to the inside of the slide block 23 through the return spring 27;

[0035] This design allows the return springs 27 outside the two sets of locking rods 25 to apply opposing elastic forces to the two sets of locking rods 25, so that the opposite ends of the two sets of locking rods 25 can be quickly inserted into the locking cylinders 12 on the two sets of bearing sleeves 9.

[0036] In other embodiments, the outer wall of the slip ring 24 is fully fitted with the inner wall of the slide block 23;

[0037] This design effectively prevents the slip ring 24 from shaking within the slide block 23, thereby improving the stability of the slip ring 24 within the slide block 23.

[0038] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
