Description

Technical Field

[0001] This utility model relates to the field of end face toothed bell-shaped shell processing, specifically, to an end face toothed bell-shaped shell tooth profile processing device. Background Technology

[0002] As a crucial component in automotive transmissions and industrial machinery drive systems, the precision and quality of the end-face tooth profile of bell-shaped housings play a key role in transmission performance. With continuous technological advancements in this field, the requirements for machining the end-face tooth profiles of bell-shaped housings are becoming increasingly stringent. Not only are higher precision sought to ensure smooth transmission, but new demands are also placed on machining efficiency, making the development of highly efficient and precise machining equipment an urgent priority.

[0003] The fixtures of existing processing equipment usually adopt a fixed structure, which is inconvenient to clamp and fix bell-shaped shells with different specifications of end face teeth. They lack versatility, which means that the fixtures need to be adjusted or the matching parts need to be replaced frequently when changing workpieces. This not only increases the complexity of operation, but also reduces production efficiency.

[0004] Furthermore, during the machining of the end face bell-shaped shell teeth, if the metal shavings generated during cutting are not removed in time, they will adhere to the workpiece surface or the tooth grooves. These residual shavings will interfere with subsequent machining processes and affect the machining accuracy and surface quality of the tooth grooves.

[0005] Therefore, we have made improvements to this and proposed a device for machining the end face of bell-shaped shell teeth. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a tooth profile processing device for bell-shaped shells with end faces, which solves the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A toothed bell-shaped shell machining device is provided to solve the above problems.

[0009] The application is as follows:

[0010] The system includes a processing table, a fixed frame fixedly mounted on the upper surface of the processing table, and a rotating cylinder rotatably connected inside the fixed frame. The upper surface of the rotating cylinder is provided with a bell-shaped shell body with end face teeth, and a clamping mechanism is provided between the bell-shaped shell body and the rotating cylinder. A rotating mechanism is provided between the rotating cylinder and the fixed frame. A support rod is fixedly mounted on the upper surface of the processing table, and an integrated base is fixedly mounted on the upper surface of the support rod. A waste blowing mechanism is fixedly mounted on one side surface of the integrated base, and a processing head is mounted on the lower surface of the integrated base.

[0011] The clamping mechanism includes four sliding grooves, all of which are located on the upper surface of the rotating cylinder. An I-shaped slider is slidably connected inside the sliding groove, and a fixing block is fixedly installed on the upper surface of the I-shaped slider. A rubber block is fixedly installed on one side surface of the fixing block.

[0012] As a preferred technical solution of this application, a rotating block is rotatably connected to the top of the rotating cylinder, and the rotating block is rectangular in shape. Connecting rods are rotatably connected to the surfaces of the four corners of the rotating block, and the other end of the connecting rod is rotatably connected to the lower surface of the I-shaped slider. The connecting rod is L-shaped.

[0013] As a preferred technical solution of this application, an installation block is fixedly installed on the lower surface of the I-shaped slider on one side, and a hydraulic rod is fixedly installed inside the rotating cylinder, with the telescopic end of the hydraulic rod fixedly connected to the installation block.

[0014] As a preferred technical solution of this application, the rotating mechanism includes a worm gear ring, which is fixedly installed on the outside of the rotating cylinder. A motor is fixedly installed inside the fixed frame, and a worm is fixedly connected to the output end of the motor. The other end of the worm is rotatably connected to the fixed frame, and the worm is meshed with the worm gear ring.

[0015] As a preferred technical solution of this application, the waste blowing mechanism includes a fixed frame, and an installation pipe is rotatably connected inside the fixed frame. Several nozzles are fixedly installed on the surface of the installation pipe. A blower is fixedly installed on one side surface of the integrated base, and an air outlet pipe is located on the lower surface of the blower.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. The clamping mechanism, with its hydraulic drive and linkage structure design, allows the four fixed blocks to move radially synchronously, quickly adapting to changes in workpiece diameter. This eliminates the need for manual adjustment of the fixture or replacement of components, significantly reducing changeover time. The rubber blocks prevent excessive clamping force from deforming the workpiece while providing stable friction to prevent machining displacement, making the clamping process safer and more reliable.

[0020] 2. By using the waste blowing mechanism, high-pressure airflow forms a fan-shaped airflow curtain covering the processing area through multiple sets of nozzles, blowing away metal waste attached to the surface of the workpiece or in the toothed grooves in real time, avoiding dimensional errors and surface scratches caused by waste embedding. The adjustable nozzle angle and blowing height can adapt to different toothed structures, ensuring cleaning without dead angles. Attached Figure Description

In addition, the terms "first" and "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] To address the technical problems in the background art, the following end-face toothed bell-shaped shell tooth profile machining apparatus is provided:

[0033] Combination Figure 1 - Figure 4 As shown, the end face toothed bell-shaped shell tooth processing device provided by this utility model includes a processing table 1. A fixed frame 2 is fixedly installed on the upper surface of the processing table 1, and a rotating cylinder 3 is rotatably connected inside the fixed frame 2. An end face toothed bell-shaped shell body 4 is provided on the upper surface of the rotating cylinder 3, and a clamping mechanism 5 is provided between the toothed bell-shaped shell body 4 and the rotating cylinder 3. A rotating mechanism 6 is provided between the rotating cylinder 3 and the fixed frame 2. A support rod 7 is fixedly installed on the upper surface of the processing table 1, and an integrated seat 8 is fixedly installed on the upper surface of the support rod 7. A waste blowing mechanism 9 is fixedly installed on one side surface of the integrated seat 8, and a processing head 10 is installed on the lower surface of the integrated seat 8. The clamping mechanism 5 includes a sliding groove 501, and four sliding grooves 501 are provided. All four sliding grooves 501 are provided on the upper surface of the rotating cylinder 3. An I-shaped slider 502 is slidably connected inside the sliding groove 501, and a fixing block 503 is fixedly installed on the upper surface of the I-shaped slider 502. A rubber block 504 is fixedly installed on one side surface of the fixing block 503.

[0034] In this embodiment: In the clamping mechanism 5, the I-shaped sliders 502 sliding in the four grooves 501 drive the fixed blocks 503 to synchronously retract or expand radially, which can quickly adapt to bell-shaped shells of different diameters. The rubber block 504 buffers the clamping force and increases the friction, ensuring that the workpiece is stable and free from deformation. At the same time, the waste blowing mechanism 9 covers the processing area in real time through the high-pressure airflow nozzle on the side of the integrated seat 8, effectively removing the residual metal waste in the toothed grooves, avoiding precision loss and surface scratches. The synergistic effect of the two improves the equipment's versatility, processing stability and finished product quality.

[0035] In a preferred embodiment, a rotating block 505 is rotatably connected to the top of the rotating cylinder 3, and the rotating block 505 is rectangular. Connecting rods 506 are rotatably connected to the four corner surfaces of the rotating block 505, and the other end of the connecting rod 506 is rotatably connected to the lower surface of the I-shaped slider 502. The connecting rod 506 is L-shaped.

[0036] In this embodiment, the top of the rotating cylinder 3 forms a linkage clamping structure with a rectangular rotating block 505 and four sets of L-shaped connecting rods 506. When the rotating block 505 is driven to rotate, the L-shaped connecting rods 506 connected at its four corners push or pull back the four I-shaped sliders 502 in sync, so as to realize the radial synchronous displacement of the fixed block 503, ensuring that the clamping process is accurate and synchronous without deviation. When adapting to workpieces of different diameters, no complicated adjustment is required, which significantly improves the clamping efficiency and stability.

[0037] In a preferred embodiment, an mounting block 507 is fixedly installed on the lower surface of one side of the I-shaped slider 502, and a hydraulic rod 508 is fixedly installed inside the rotating cylinder 3, with the telescopic end of the hydraulic rod 508 fixedly connected to the mounting block 507.

[0038] In this embodiment: by setting an mounting block 507 on the lower surface of the single-sided I-shaped slider 502, and directly driving its extension and retraction movement by the hydraulic rod 508 inside the rotating cylinder 3, the automatic control of the clamping mechanism 5 is realized; the pushing and pulling force of the hydraulic rod 508 is converted into the linear displacement of the I-shaped slider 502 through the mounting block 507, which drives the four sets of fixing blocks 503 to complete the clamping or releasing action simultaneously, ensuring the stability and accuracy of the clamping force, simplifying the power transmission path, and avoiding multi-axis linkage errors.

[0039] In a preferred embodiment, the rotating mechanism 6 includes a worm gear ring 601, which is fixedly installed on the outside of the rotating cylinder 3. A motor 602 is fixedly installed inside the fixed frame 2, and a worm 603 is fixedly connected to the output end of the motor 602. The other end of the worm 603 is rotatably connected to the fixed frame 2, and the worm 603 is meshed with the worm gear ring 601.

[0040] In this embodiment: the motor 602 drives the worm gear 603 to rotate, which in turn drives the worm wheel ring 601 fixed to the outside of the rotating cylinder 3, so that the rotating cylinder 3 can rotate stably, which is convenient for machining different tooth grooves. The self-locking characteristic of the worm wheel effectively prevents reverse rotation caused by external force during the machining process, ensuring machining accuracy.

[0041] In a preferred embodiment, the waste blowing mechanism 9 includes a fixed frame 901, and an installation pipe 902 is rotatably connected inside the fixed frame 901. A plurality of nozzles 903 are fixedly installed on the surface of the installation pipe 902. A blower 904 is fixedly installed on one side surface of the integrated base 8, and an air outlet pipe 905 is located on the lower surface of the blower 904. The air outlet pipe 905 is connected to the installation pipe 902.

[0042] In this embodiment, the blower 904 delivers high-pressure airflow to the mounting pipe 902 through the air outlet pipe 905, and forms a fan-shaped airflow curtain through multiple sets of nozzles 903 on the surface, which accurately covers the workpiece surface and toothed grooves, and blows away metal waste in real time to avoid interference with processing accuracy. The mounting pipe 902 is rotatable, which can flexibly adjust the blowing angle of the nozzles 903 to adapt to the cleaning needs of different toothed structures and improve the waste removal efficiency.

[0043] In a preferred embodiment, a first knob 906 is threadedly connected to one side surface of the fixing bracket 901, a fixing sleeve 907 is fixedly installed on one side surface of the integrated base 8, and a connecting plate 908 is slidably connected inside the fixing sleeve 907, and the lower end surface of the connecting plate 908 is fixedly connected to the fixing bracket 901. A second knob 909 is threadedly connected to the outside of the fixing sleeve 907.

[0044] In this embodiment: rotating the first knob 906 can finely adjust the tilt angle of the mounting tube 902 inside the fixing frame 901, precisely control the airflow spray direction of the nozzle 903, and adapt to the cleaning needs of different toothed structures; at the same time, by releasing the second knob 909 to allow the connecting plate 908 to slide up and down inside the fixing sleeve 907, the installation height of the fixing frame 901 can be quickly adjusted to ensure that the airflow coverage covers the entire processing area.

[0045] Specifically, the working principle of this solution is as follows:

[0046] In use, the telescopic end of the hydraulic rod 508 pushes the single-sided I-beam slider 502 to move linearly along the slide groove 501 through the mounting block 507. Through the mechanical linkage of four sets of L-shaped connecting rods 506, the rotating block 505 rotates synchronously, causing the four I-beam sliders 502 to move radially synchronously. This drives the fixed block 503 to clamp or release the workpiece. The rubber block 504 buffers the clamping force and increases the friction, ensuring that the workpiece is stable and free from deformation. The motor 602 drives the worm gear 603 to rotate. Through meshing with the worm wheel ring 601 fixed outside the rotating cylinder 3, the rotating cylinder 3 achieves stable low-speed rotation. This, in conjunction with the machining head 10, completes the tooth profile machining. The self-locking characteristic of the worm wheel prevents reverse rotation during machining, ensuring accuracy.

[0047] The blower 904 delivers high-pressure airflow to the mounting pipe 902 through the air outlet pipe 905. The airflow forms a fan-shaped airflow curtain through multiple sets of nozzles 903 on the surface, blowing away waste from the processing area in real time and avoiding precision loss. Rotating the first knob 906 can finely adjust the tilt angle of the mounting pipe 902 and precisely control the airflow direction of the nozzles 903. Releasing the second knob 909 allows the connecting plate 908 to slide within the fixing sleeve 907, which can quickly adjust the height of the fixing frame 901 to ensure that the airflow covers the entire processing area.

[0048] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0049] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
