Description

Technical Field

[0001] This utility model relates to the technical field of bearing processing, and in particular to an end face support device for bearing processing. Background Technology

[0002] The end face support device for bearing machining is a precision fixture used for positioning and supporting the bearing rings (inner or outer rings) from the end face of the part during machining such as turning and grinding.

[0003] In related technologies, existing end-face support devices for bearing machining typically employ a structure combining strong magnetic adsorption and mechanical pressure arms. The strong magnetic force easily causes elastic deformation of thin-walled bearing rings, resulting in accurate shape during machining, but the workpiece springs back after removal, leading to a loss of precision. Furthermore, their centering mechanisms are mostly fixed, lacking versatility; changing product models often requires tooling replacement, which is cumbersome and inefficient. Independent pressure arm mechanisms not only obstruct the machining path and limit the grinding head's approach to the workpiece from multiple angles, affecting the flexibility of the machining process, but also pose a risk of concentrated clamping force, damaging the workpiece's finished surface and reducing bearing machining accuracy and efficiency.

Detailed Implementation

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The end face support device for bearing processing according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0017] like Figures 1-4 As shown, the end face support device for bearing processing according to this utility model embodiment may include a support plate 1, a bearing ring 2, a drive adjustment component 3, and a positioning mechanism 4.

[0018] The bearing ring 2 is rotatably connected to the support plate 1 and is located at the center of the support plate 1. The drive adjustment component 3 is movably connected to the support plate 1 and drives the positioning mechanism 4 to move and adjust synchronously.

[0019] It should be noted that the bearing ring 2 described in this embodiment is made of magnetic material, which can magnetically adsorb bearing workpieces made of iron, steel and their alloys, and can assist in positioning and pressing the bearing workpieces during centering and separation.

[0020] The positioning mechanism 4 includes a pressing component 41 and an adjustable centering component 42.

[0021] The pressing component 41 is mounted on the drive adjustment component 3, and the adjustable centering component 42 is movably connected to the support plate 1 and is positioned opposite to the pressing component 41.

[0022] It should be noted that the pressing component 41 described in this embodiment is located above the support plate 1, and the adjustable centering component 42 is located below the support plate 1. By driving the adjustment component 3, the pressing component 41 and the adjustable centering component 42 can be moved and adjusted perpendicularly to the support plate 1 to achieve centering or pressing of the bearing workpiece.

[0023] Specifically, in practical applications, when relevant personnel install the device, they connect and fix it through the through-hole bolts in the mounting bracket 34 on one side of the support plate 1. In the initial state, the first drive device 33 is in a retracted state, the adjustment frame 32 is at the highest point, and the rotating pressing component 41 is at the highest point. The positioning column 421 passes through the bearing ring 2 and extends to the upper part of the bearing ring 2.

[0024] When positioning the bearing workpiece, the inner or outer ring of the bearing is placed on the positioning post 421, so that the inner or outer ring of the bearing contacts the outer wall of the positioning post 421, thus centering the workpiece. As the first driving device 33 extends, it pushes the adjusting frame 32 to slide along the height direction of the limiting frame 31, and uses two symmetrically arranged limiting frames 31 to limit the downward movement, so that the inner or outer ring of the bearing contacts the bearing ring 2 and is magnetically attracted to the bearing ring 2. As the positioning post 421 moves downward, it gradually separates from the bearing workpiece. At the same time, multiple pressing rods 413 press on the upper part of the bearing to achieve the positioning of the bearing workpiece.

[0025] When machining bearing workpieces, grinding is performed on the inner wall, outer wall and raceway of the inner or outer ring. The second drive device 411 rotates, driving multiple connecting plates 412 to rotate. At the same time, multiple pressing rods 413 make frictional contact with the upper part of the bearing workpiece, causing the bearing workpiece and the bearing ring 2 to rotate synchronously. The grinding head performs grinding on the outside of the bearing on one side of the support plate 1, or extends into the bearing ring 2 through the lower part of the support plate 1 to perform grinding on the inner wall of the bearing.

[0026] In one embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the drive adjustment assembly 3 includes two symmetrically arranged limit frames 31, an adjustment frame 32, two sets of symmetrically arranged first drive devices 33, and a mounting bracket 34.

[0027] Two symmetrically arranged limiting frames 31 are mounted on the support plate 1. The mounting bracket 34 is mounted on the two symmetrically arranged limiting frames 31 and is located on one side of the support plate 1. The adjusting frame 32 is movably connected to the two symmetrically arranged limiting frames 31 and passes through the two symmetrically arranged limiting frames 31. Two sets of symmetrically arranged first driving devices 33 are respectively mounted on the two symmetrically arranged limiting frames 31, and the output ends of the two sets of symmetrically arranged first driving devices 33 are mounted on the adjusting frame 32.

[0028] It should be noted that the first driving device 33 proposed in the above embodiment is a cylinder, and two symmetrically arranged limiting frames 31 are distributed on both sides of the support plate 1. The adjusting frame 32 is set in the form of a rectangular frame, which runs through the upper and lower parts and slides within the two symmetrically distributed limiting frames 31. The adjusting frame 32 can be moved up and down by the extension and retraction adjustment of the output end of the first driving device 33, which simultaneously drives the positioning mechanism 4 to move up and down for adjustment.

[0029] In one embodiment of this utility model, such as Figures 1-4 As shown, the pressing assembly 41 includes a second driving device 411, multiple connecting plates 412, and multiple pressing rods 413.

[0030] The second driving device 411 is mounted on the adjustment frame 32, multiple connecting plates 412 are mounted on the output end of the second driving device 411, and multiple pressing rods 413 are respectively mounted on the multiple pressing rods 413.

[0031] It should be noted that the second driving device 411 proposed in the above embodiment adopts a rotary motor, the output end of which is connected to multiple connecting plates 412. The connecting plates 412 are bent at an obtuse angle and are respectively connected to multiple pressing rods 413 at the bottom. The pressing rods 413 are made of rubber to increase the friction with the bearing workpiece, and it is easy to drive the workpiece to rotate after pressing.

[0032] In one embodiment of this utility model, such as Figures 2-4 As shown, the adjustable centering assembly 42 includes a positioning post 421 and an adjusting stud 422.

[0033] The adjusting stud 422 is disposed on the adjusting frame 32 and passes through the adjusting frame 32 and is threadedly connected to the adjusting frame 32. The positioning pin 421 is rotatably connected to the adjusting stud 422.

[0034] It should be noted that the positioning post 421 described in this embodiment is made of rubber and is located inside the adjustment frame 32. The height of the positioning post 421 can be adjusted by rotating the adjusting stud 422, thereby adjusting the length of the positioning post 421 extending into the bearing ring 2.

[0035] In one embodiment of this utility model, such as Figures 1-4 As shown, the positioning post 421 is arranged in the shape of a frustum, and the maximum diameter of the positioning post 421 is equal to the inner diameter of the bearing ring 2.

[0036] It should be noted that the positioning column 421 described in this embodiment supports bearing parts of different diameters through a frustum-shaped structure.

[0037] In summary, the end face support device for bearing processing according to this utility model adopts an integrated structure of dynamic centering and flexible clamping. By driving the adjustment component to move and adjust the positioning mechanism, the device improves the positioning accuracy of the workpiece, while also improving versatility and processing accessibility. It enables rapid production changeover of bearings of different specifications and all-round one-time clamping and processing of the inner and outer walls and raceways of the bearing, effectively avoiding workpiece deformation and ensuring processing accuracy.
