Description

A bending device for processing automotive engine bearing parts Technical Field

[0001] This utility model relates to the field of bearing parts processing technology, specifically a bending device for processing automotive engine bearing parts. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Based on the different frictional properties of the moving elements, bearings can be divided into two main categories: rolling bearings and sliding bearings.

[0003] In existing processing procedures, folding operations are often performed manually or with semi-automatic equipment. This not only consumes a lot of manpower and resources, but also makes it difficult to guarantee the accuracy and consistency of the folding. During processing, the already processed parts must be removed before the unprocessed parts can be installed for folding. This operation is too cumbersome and not conducive to large-scale folding processing.

[0004] Therefore, this utility model provides a bending device for processing automotive engine bearing parts to solve the above problems. Summary of the Invention

A third hydraulic telescopic rod is fixedly installed on the second mounting frame, and an extrusion head is fixedly installed on the lower telescopic rod of the third hydraulic telescopic rod.

[0009] As a preferred technical solution of this application, the diameter of the lower outer wall of the folding head is larger than the diameter of the upper outer wall, and the lower side of the extrusion head is higher than the upper surface of the lower end of the folding head.

[0014] (III) Beneficial Effects

[0015] 1. The bearing parts to be folded are clamped and fixed by multiple calipers and clamps on multiple chucks.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a bending device for processing automotive engine bearing parts, as shown in Figures 1-4. The bending device for processing bearing parts includes a bending machine body 1. A bracket 2 is fixedly installed on the right end of the bending machine body 1. A drive frame 3 is installed on the upper end of the bracket 2 via a slide rail. A bending assembly is provided on the lower end of the drive frame 3. A clamping assembly is installed on the upper left side of the bending machine body 1 via a slide rail. The bending assembly includes a first mounting frame 4. The first mounting frame 4 is fixedly installed on the lower left side of the drive frame 3. A first hydraulic telescopic rod 5 is fixedly installed inside the left side of the first mounting frame 4. A bending head 6 is fixedly installed on the lower telescopic rod of the first hydraulic telescopic rod 5. Multiple sets of second hydraulic telescopic rods 7 are symmetrically installed on the left end of the first mounting frame 4. A second mounting frame 8 is fixedly installed on the left telescopic rod of the multiple sets of second hydraulic telescopic rods 7. A third hydraulic telescopic rod 9 is fixedly installed on the second mounting frame 8. A pressing head 10 is fixedly installed on the lower telescopic rod of the third hydraulic telescopic rod 9.

[0025] The bearing component to be folded is fixed in the clamping assembly, and the clamping assembly moves to align the bearing component to be folded with the folding head 6 and the pressing head 10. Then, the first hydraulic telescopic rod 5 and the third hydraulic telescopic rod 9 drive the folding head 6 and the pressing head 10 to move down into the inner and outer walls of the bearing component to be folded. At the same time, multiple sets of second hydraulic telescopic rods 7 drive the second mounting bracket 8, the third hydraulic telescopic rod 9 and the pressing head 10 to move closer to the first hydraulic telescopic rod 5 and the folding head 6. Then, the clamping assembly drives the bearing component to be folded to rotate, so that the rotating bearing component to be folded is folded by the folding head 6 and the pressing head 10.

[0026] The diameter of the lower outer wall of the folding head 6 is larger than the diameter of the upper outer wall, and the lower side of the extrusion head 10 is higher than the upper surface of the lower end of the folding head 6.

[0027] Based on the size of the upper and lower ends of the folding head 6, when the slide plate 11 approaches the folding head 6, it clamps and bends the bearing component to be folded. As the clamping assembly rotates the bearing component to be folded, the folding of the bearing component is completed.

[0028] The clamping assembly includes a slide plate 11, which is mounted on the upper side of the folding machine body 1 via a slide rail. Multiple positioning plates 13 are fixedly installed on the upper side of the slide plate 11. Positioning frames 14 are fixedly installed on the upper side of each of the multiple positioning plates 13. Each of the multiple positioning frames 14 has an opening 15. A chuck 16 is installed between the multiple positioning plates 13 and the multiple positioning frames 14. Multiple clamps 17 are provided on the upper side of each of the multiple chucks 16. A clamping plate 18 is fixedly installed on the opposite side of each of the multiple clamps 17. A motor 19 is fixedly installed on the upper side of each of the multiple positioning frames 14. The multiple motors 19 are fixedly connected to the multiple chucks 16.

[0029] In use, the bearing parts to be processed are placed on multiple sets of chucks 16, and then clamped and fixed by multiple sets of clamps 17 and multiple sets of clamping plates 18. The slide plate 11 moves multiple sets of positioning plates 13, multiple sets of positioning frames 14 and multiple sets of chucks 16 to the underside of the folding head 6 and the pressing head 10 via the slide rail. At this time, the folding head 6 and the pressing head 10 are in contact with the inner and outer walls of the bearing parts to be processed. Then, the motor 19 drives the chucks 16 to rotate, thereby driving the bearing parts to be processed held by the multiple sets of clamps 17 and multiple sets of clamping plates 18. As the bearing components rotate, multiple sets of second hydraulic telescopic rods 7 drive the second mounting bracket 8, the third hydraulic telescopic rod 9, and the extrusion head 10 to approach the folding head 6, thus completing the folding process of the bearing components to be processed. At the same time, while the bearing components to be processed are being folded, the processed bearing components can be removed from between multiple sets of clamping plates 18, and the unprocessed bearing components can be placed on multiple sets of chucks 16 and clamped and fixed by multiple sets of clamps 17 and multiple sets of clamping plates 18 without interrupting the processing flow.

[0030] The inner diameter of the multiple sets of ports 15 is larger than the outer diameter of the multiple sets of chucks 16, and the center point of the multiple sets of chucks 16 and the center point of the multiple sets of ports 15 are on the same vertical line.

[0031] Multiple sets of chucks 16 can rotate within multiple sets of ports 15, ensuring that the multiple sets of chucks 16 drive the bearing parts to be processed to rotate stably without jamming, thereby ensuring the folding effect of the bearing parts to be processed.

[0032] Multiple sets of calibration instruments 12 are fixedly installed on the upper left side of the slide plate 11, and the multiple sets of calibration instruments 12 are arranged parallel to the left side of the multiple sets of positioning plates 13.

[0033] By setting multiple sets of calibration instruments 12, the positions of multiple sets of positioning plates 13 on the slide plate 11 are positioned to avoid the position of multiple sets of positioning plates 13 on the slide plate 11 being offset, thus preventing the bearing parts to be processed from being accurately aligned with the folding head 6 and the extrusion head 10.

[0034] The surfaces of the clamps 18 on opposite sides of the multi-clamp 17 are all frosted, and the surfaces of the clamps 18 on opposite sides of the multi-clamp 17 are all curved.

[0035] The frosted texture on the opposite side of the multiple clamping plates 18 increases the friction between the clamping plates 18 and the bearing components, making the clamping more stable. The arc shape allows for better contact with the surface of the bearing components, preventing slippage or displacement during rotation and further ensuring the accuracy and stability of the folding.

[0036] Working Principle: When performing edge bending processing on automotive engine bearing parts, the bearing parts to be processed are first placed on multiple sets of chucks 16 of the clamping assembly. Multiple sets of clamps 17 and their clamping plates 18 securely hold the bearing parts. The slide plate 11 moves to the left along the bending machine body 1 via the slide rail, bringing the bearing parts below and aligned with the bending head 6 and pressing head 10 of the bending assembly. At this time, the bending head 6 and pressing head 10 are located on the inner and outer walls of the bearing parts, respectively, preparing for the subsequent bending operation. After the device is started, the first hydraulic telescopic rod 5 and the third hydraulic telescopic rod 9 drive the bending head 6 and pressing head 10 downwards, tightly fitting the inner and outer walls of the bearing parts. Simultaneously, multiple sets of second hydraulic telescopic rods... When lever 7 is activated, it drives the second mounting bracket 8, the third hydraulic telescopic lever 9, and the extrusion head 10 to move towards the folding head 6, gradually reducing the distance between the extrusion head 10 and the folding head 6 and bringing them into contact with the inner and outer walls of the bearing component. The folding operation on the bearing component begins. During this process, motor 19 drives chuck 16 to rotate, which in turn drives the clamped bearing component to rotate. It is worth noting that while the bearing component to be processed is being folded, the operator can easily remove the folded bearing component from between multiple sets of clamps 17 and multiple sets of clamping plates 18 on another set of chucks 16, and place the next bearing component to be processed on the chuck 16 on which the folded bearing component has been removed, thus achieving continuous processing and greatly improving production efficiency.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
