Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of bearing processing, and more specifically, to an adjustable positioning and clamping device for bearing processing. Background Technology

[0002] In the bearing manufacturing process, polishing of the inner and outer diameters is a crucial step in ensuring bearing precision and service life. This step requires stable clamping and positioning of the bearing to ensure it does not shift under the action of the high-speed rotating polishing tool, thereby avoiding quality problems such as scratches and dimensional deviations on the polished surface.

[0003] Currently, most positioning and clamping devices used in bearing polishing processes are fixed structures, with relatively simple clamping dimensions and positioning methods. For bearings of different specifications, corresponding fixtures must be changed to achieve effective clamping, which not only increases tooling changeover time and reduces production efficiency but also raises equipment investment costs. A more prominent problem is that existing devices have significant shortcomings in meeting the clamping and positioning requirements for both inner and outer diameter polishing: if an outer diameter clamping method is used, although it can meet the outer diameter polishing requirements, it will obstruct the inner diameter machining area, requiring secondary clamping for inner diameter polishing, leading to accumulated positioning errors; if an inner diameter support method is used, the bearing is prone to shaking due to radial forces during outer diameter polishing, affecting polishing accuracy.

[0004] With the increasing demand for multi-variety, small-batch production in the bearing industry, the inconvenience of existing positioning and clamping devices has become an important factor restricting the improvement of production efficiency and product quality. Therefore, there is an urgent need for an adjustable clamping device that can flexibly adapt to bearings of different specifications and meet the positioning requirements for polishing of inner and outer diameters. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide an adjustable positioning and clamping device for bearing processing, which solves the technical problem in the prior art that it is inconvenient to clamp and position the bearing during the polishing of the inner and outer diameters.

[0006] According to one aspect, at least one embodiment of this disclosure provides an adjustable positioning and clamping device for bearing machining, comprising:

[0007] The frame and the conveyor belt, wherein the conveyor belt is disposed inside the frame;

[0008] A sliding plate and an infeed / outfeed positioning assembly, wherein the sliding plate is fixed inside the frame and the infeed / outfeed positioning assembly is disposed inside the frame and the sliding plate;

[0009] A clamping assembly is disposed inside the slide plate and the frame;

[0010] The clamping assembly includes an elongated hole formed on the flat portion of the slide plate. A base frame is provided at the bottom of the slide plate, and a lifting frame connected by a vertical linear drive is provided on the base frame. A pair of clamping rods are provided inside the lifting frame.

[0011] As a further technical solution, a screw is rotatably connected to the inside of the lifting frame. The screw is driven to rotate by electricity. A pair of guide rods are arranged laterally inside the lifting frame. The clamping rods are respectively connected to both ends of the screw through threaded engagement.

[0012] As a further technical solution, the lower ends of the clamping rods are all slidably connected to the guide rods, the surface of the sliding plate is provided with a horizontal groove, the horizontal groove is connected to the elongated hole, and a support plate is provided on the clamping rods.

[0013] As a further technical solution, the feeding and discharging positioning component includes a pair of side holes, which are opened on both sides of the frame and located above the conveyor belt. Both ends of the top of the frame are provided with pusher frames that are driven to rotate by electricity.

[0014] As a further technical solution, the pusher is located inside the side hole, and an outer plate is provided at one end of the frame. A positioning frame connected by a horizontal linear drive is installed on the outer plate, and the positioning frame is located at the end of the slide plate.

[0015] As a further technical solution, the inclined part of the slide plate has a discharge port, and a flat plate is rotatably connected to the discharge port by a pin. A cylinder is rotatably connected between the bottom of the flat plate and the bottom of the slide plate by a pin.

[0016] As a further technical solution, the clamping rod has concave and convex arc-shaped transition surfaces at its two opposite ends.

[0017] As a further technical solution, a sliding hopper is provided inside the frame.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] In this disclosure, the clamping assembly, through its adjustable structure, solves the problem of poor adaptability of traditional devices. The screw drives the clamping rod to move along the guide rod, and the spacing can be adjusted according to the bearing specifications. The concave and convex arc surfaces respectively adapt to the outer and inner diameters of the bearing, ensuring stable clamping without obstructing the machining area and meeting the polishing requirements of both inner and outer diameters. The height adjustment of the lifting frame adapts to bearings of different thicknesses, and the support plate provides bottom support to prevent wobbling during machining. This design eliminates the need to change fixtures, reduces tooling time, improves machining accuracy and efficiency, adapts to the production of bearings of various specifications, and has excellent auxiliary machining effects.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-3 As shown, an adjustable positioning and clamping device for bearing machining is illustrated in one embodiment of this disclosure, comprising:

[0032] The frame 1 and the conveyor belt 2 are disposed inside the frame 1;

[0033] The slide plate 3 and the infeed / outfeed positioning component 5 are provided. The slide plate 3 is fixed inside the frame 1, and the infeed / outfeed positioning component 5 is provided inside the frame 1 and the slide plate 3.

[0034] Clamping assembly 4, which is disposed inside the slide plate 3 and the frame 1;

[0035] The clamping assembly 4 includes an elongated hole 4-1, which is formed on the flat portion of the slide plate 3. A base frame 4-2 is provided at the bottom of the slide plate 3. A lifting frame 4-3 connected by a vertical linear drive is provided on the base frame 4-2. A pair of clamping rods 4-4 are provided inside the lifting frame 4-3. A screw 4-5 is rotatably connected to the inside of the lifting frame 4-3. The screw 4-5 is driven to rotate by electricity. A pair of guide rods 4-6 are provided to the inside of the lifting frame 4-3. The clamping rods 4-4 are respectively connected to both ends of the screw 4-5 by threaded engagement. The lower ends of the clamping rods 4-4 are slidably fitted with the guide rods 4-6. A transverse groove 4-7 is formed on the surface of the slide plate 3. The transverse groove 4-7 is connected to the elongated hole 4-1. A support plate 4-8 is provided on the clamping rods 4-4.

[0036] In some examples, a clamping assembly 4 is designed to achieve precise clamping of the bearing's inner and outer diameters. This assembly includes a U-shaped base frame 4-2 at the bottom of the slide plate 3. A lifting frame 4-3 is connected to the base frame 4-2 via a vertical linear drive device (such as a hydraulic cylinder), which can drive the lifting frame 4-3 to rise and fall vertically. After clamping the bearing, it can be raised to facilitate polishing of the inner and outer diameters. The screw 4-5 inside the lifting frame 4-3 is connected to the bearing for lateral rotation. The threads at both ends are in opposite directions and are threaded into a pair of clamping rods 4-4. The screw 4-5 is driven to rotate by a motor, causing the clamping rods 4-4 to move laterally.

[0037] The guide rod 4-6 inside the lifting frame 4-3 is parallel to the screw 4-5, and both ends are fixed to the inner wall of the lifting frame 4-3. The sliding sleeve at the lower end of the clamping rod 4-4 slides and fits with the guide rod 4-6, restricting the clamping rod 4-4 to only move along the guide rod 4-6 and preventing rotation. The elongated hole 4-1 on the surface of the slide plate 3 is opened laterally to form a moving channel for the clamping rod 4-4. The support plate 4-8 at the upper end of the clamping rod 4-4 is located above the elongated hole 4-1. When it moves downward, it can enter the transverse groove 4-7 to avoid affecting the sliding of the bearing. The support plate 4-8 can support the bottom of the bearing.

[0038] During operation, the vertical linear drive pushes the lifting frame 4-3 upward, causing the support plate 4-8 to fit against the bearing. The motor drives the screw 4-5 to rotate, and the clamping rods 4-4 at both ends move towards each other under the constraint of the guide rod 4-6, clamping the inner or outer diameter of the bearing from both sides of the support plate 4-8. Reversing the rotation of the screw 4-5 causes the clamping rods 4-4 to move in the opposite direction, releasing the bearing. The guide rod 4-6 ensures a smooth and non-offset clamping process. The height adjustment of the lifting frame 4-3 adapts to bearings of different thicknesses, and the elongated hole 4-1 and the transverse groove 4-7 provide sufficient movement space for the clamping rods 4-4. This assembly, through adjustable clamping, meets the positioning requirements during the processing of bearings of different specifications, ensuring processing accuracy.

[0039] like Figures 1-3As shown in the figure, the feeding and discharging positioning component 5 in this embodiment includes a pair of side holes 5-1. The side holes 5-1 are opened on both sides of the frame 1 and are located above the conveyor belt 2. Both ends of the top of the frame 1 are provided with pusher frames 5-2 that are driven by electricity to rotate. The pusher frames 5-2 are located in the side holes 5-1. One end of the frame 1 is provided with an outer plate 5-3. A positioning frame connected by a horizontal linear drive is installed on the outer plate 5-3. The positioning frame is located at the end of the slide plate 3. The inclined part of the slide plate 3 has a discharge port 5-5. A flat plate 5-6 is rotatably connected to the discharge port 5-5 by a pin. A cylinder 5-7 is rotatably connected between the bottom of the flat plate 5-6 and the bottom of the slide plate 3 by a pin.

[0040] In some examples, to achieve the effect of bearing feeding and discharging positioning, a feeding / discharging positioning component 5 is designed. This component includes side holes 5-1 on both sides of the frame 1, which are symmetrically distributed. The pusher frame 5-2 is driven to rotate by a motor. The rotating end extends into the frame 1 through the side holes 5-1, and can push the bearing towards the center of the slide plate 3, and can push the bearing to the centered position during the process. The outer plate 5-3 at one end of the frame 1 is fixed laterally. The cylinder of the horizontal linear drive device (such as a cylinder) is fixed on the outer plate 5-3. The piston rod is connected to the positioning frame. The positioning frame is located at the end of the slide plate 3 and can extend and retract in the horizontal direction. It can extend the positioning frame to determine the position where the bearing slides on the surface of the slide plate 3.

[0041] The inclined portion of slide plate 3 smoothly transitions to the flat portion. The discharge port 5-5 is located at the end of the inclined portion. The flat plate 5-6 is rotatably connected to the edge of the discharge port 5-5 via a pin, and can be flipped downwards to open the discharge port 5-5. The cylinder body of cylinder 5-7 is connected to the bracket at the bottom of slide plate 3 via a pin, and the piston rod is connected to the lug at the bottom of flat plate 5-6 via a pin, driving flat plate 5-6 to flip. After opening, the positioning frame can push the processed bearing to be discharged to the outside at the discharge port 5-5.

[0042] During operation, the conveyor belt 2 delivers the bearing to the planar portion of the slide plate 3. The pushers 5-2 on both sides rotate synchronously, pushing the bearing to align and center it on the slide plate 3. The positioning frame extends under horizontal linear drive, blocking the bearing's forward direction and cooperating with the clamping assembly 4 to complete positioning. After processing, the cylinder 5-7 drives the plate 5-6 to flip downwards, opening the discharge port 5-5. The positioning frame then pushes the bearing outwards along the discharge port 5-5 of the slide plate 3. This assembly, through the coordinated positioning, pushing, and guiding discharge, achieves automated positioning of the bearing's infeed and discharge, adapting to the continuous processing requirements.

[0043] For example, such as Figure 1 As shown, the clamping rod 4-4 has concave and convex arc-shaped transition surfaces at its two opposite ends.

[0044] In some examples, the concave and convex arc-shaped transition surfaces of the clamping rod 4-4 at opposite ends are adapted to the outer and inner diameters of the bearing, respectively. The concave surface fits against the outer ring of the bearing, while the convex surface embeds into the inner ring, increasing the contact area. This structure ensures uniform force during clamping, preventing damage to the bearing surface, while also increasing friction to prevent slippage, ensuring the bearing remains stable and does not shift during machining, and adapting to the clamping requirements of bearings of different specifications.

[0045] For example, such as Figure 1 As shown, a sliding hopper 6 is provided inside the frame 1.

[0046] In some examples, the sliding hopper 6 inside the frame 1 is tilted and positioned directly below the discharge port 5-5. The smooth inner wall of the sliding hopper 6, combined with the tilt angle, ensures that the bearing slides smoothly while avoiding collisions caused by excessive speed, thus enabling smooth material discharge.

[0047] In actual use: the bearing is fed into the frame 1 by the conveyor belt 2, the pusher 5-2 rotates in the side hole 5-1 to push the bearing to the slide plate 3, the positioning frame extends to limit the bearing position, the vertical linear drive pushes the lifting frame 4-3 to rise, the support plate 4-8 supports the bearing, the motor drives the screw 4-5 to rotate, the clamping rod 4-4 moves towards each other along the guide rod 4-6, and clamps the bearing through the concave and convex arc surfaces. After processing is completed, the screw 4-5 reverses to release the clamping rod 4-4, the lifting frame 4-3 descends, the cylinder 5-7 drives the plate 5-6 to flip and open the discharge port 5-5, the positioning frame pushes the bearing, the bearing falls into the sliding hopper 6 through the discharge port 5-5 along the inclined part of the slide plate 3, and the plate 5-6 resets to wait for the next bearing to enter.
