Description

Technical Field

[0001] This utility model relates to the field of gearbox processing technology, specifically a gearbox housing rotation positioning device. Background Technology

[0002] A gearbox housing rotation positioning device is a specialized piece of equipment used for precise positioning and rotation control of the gearbox housing during machining or assembly. Through a sophisticated mechanical structure or sensor system, it achieves accurate positioning of the gearbox housing in space, ensuring machining or assembly precision. It can rotate the gearbox housing at preset angles or speeds to meet different requirements during machining or assembly. During rotation and positioning, it maintains the stability of the gearbox housing, preventing machining errors or assembly problems caused by vibration or misalignment.

[0003] A search revealed that the patent document (authorization announcement number CN208246286U) includes a connecting plate for fixing on a lathe. A first positioning post and a second positioning post are connected to the connecting plate. The first positioning post can be inserted into a first through hole and fits against the inner wall of the first inner ring layer. The second positioning post can be inserted into a second through hole and fits against the inner wall of the second inner ring layer. A threaded rod is fixedly connected to the first positioning post, and a clamping post is threadedly connected to the threaded rod. The clamping post can be inserted into the first through hole and fits against the inner wall of the first through hole. This solves the problem of inaccurate positioning and easy misalignment of the gearbox housing blank during lathe machining, achieving stable and accurate positioning of the blank and preventing misalignment during machining, thus improving product quality.

[0004] However, the above-mentioned device still has shortcomings:

[0005] The dimensions of the gearbox housing vary depending on the application scenario, which means that the mounting device needs to be changed according to different gearbox housings. If the mounting device is not changed, the gearbox housing will shift during processing, resulting in processing failure. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a gearbox housing rotation positioning device, which solves the problem that the size of the gearbox housing varies according to different usage scenarios, leading to the need to replace the fixing device according to different gearbox housings. If the fixing device is not replaced, the gearbox housing will shift during processing, resulting in processing failure.

[0007] To achieve the above objectives, this utility model proposes a gearbox housing rotation positioning device, including a tooling table, and a positioning component is disposed above the tooling table, wherein:

[0008] The positioning component includes an outer cylinder with a groove inside. An inner cylinder is rotatably connected inside the groove. A venting groove is provided at the bottom of the inner cylinder. A pressure groove is provided on the side wall of the outer cylinder. A fixing plate is slidably connected inside the pressure groove. The positions of the venting groove and the pressure groove correspond one-to-one.

[0009] Preferably, the bottom of the tooling table is fixedly connected with several bottom supports.

[0010] Preferably, the top of the tooling table is rotatably connected to a rotating shaft, the top of the rotating shaft is fixedly connected to a placement tray, and the outer cylinder is fixedly connected to the upper surface of the placement tray.

[0011] Preferably, a rotating handle is fixedly connected to the top of the inner cylinder.

[0012] Preferably, a pipe is fixedly connected to the top of the inner cylinder, and an air pump is fixedly connected to the end of the pipe away from the inner cylinder.

[0013] Preferably, the bottom of the tooling table is provided with a fixed slide groove, the bottom of the inner cylinder is provided with a fixed slot, a fixed block is slidably connected inside the fixed slide groove, a spring is provided inside the fixed slide groove, the two ends of the spring are respectively fixedly connected to the fixed block and the fixed slide groove, and the fixed block is engaged in the fixed slot.

[0014] Preferably, a gearbox housing is disposed above the positioning component, the positioning component is disposed entirely inside the gearbox housing, and a suction cup is fixedly connected to the end of the fixing plate, the suction cup abutting against the inner sidewall of the gearbox housing.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By setting up the positioning component, when fixing the gearbox housing, the gearbox housing is inserted into the positioning component, and then the inner cylinder is rotated to connect the vent groove and the pressure groove. At this time, the fixing block is inserted into the fixing slot to prevent the inner cylinder from deflecting during inflation. Then, the air pump is controlled to inject gas into the groove. As the gas is injected, it slowly rushes into the pressure groove, pushing the fixing plate out of the groove so that it abuts against the inner wall of the gearbox housing. After fixing, the inner cylinder is rotated to make the fixing block engage in the vent groove. At this time, the gas in the pressure groove is blocked by the side wall of the inner cylinder, which ensures that the fixing plate cannot move again, thus achieving the positioning effect.

[0017] The advantage of this design is that the device can accurately fix the gearbox housing of different sizes, achieving precise positioning. This precise positioning significantly reduces positioning errors during the machining process. This helps ensure the dimensional and positional accuracy of machined holes, surfaces, and other components, thereby improving the overall performance of the gearbox housing. For gearbox housings of different sizes, the precise positioning device ensures that they have the same or similar machining accuracy during processing, thus guaranteeing product consistency. It also significantly shortens the positioning and clamping time before machining, improving production efficiency. Accurate positioning also reduces machining errors and rework caused by inaccurate positioning, saving debugging time and costs. Attached Figure Description

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] like Figure 1-5 As shown, a gearbox housing rotation positioning device includes a tooling table 1, and a plurality of bottom supports 101 are fixedly connected to the bottom of the tooling table 1.

[0026] The top of the tooling table 1 is rotatably connected to a rotating shaft 4, and the top of the rotating shaft 4 is fixedly connected to a placement tray 41. The outer cylinder 51 is fixedly connected to the upper surface of the placement tray 41.

[0027] A positioning component 5 is provided above the tooling table 1. The positioning component 5 includes an outer cylinder 51. A groove 501 is provided inside the outer cylinder 51. An inner cylinder 52 is rotatably connected inside the groove 501. A pipe 201 is fixedly connected to the top of the inner cylinder 52. An air pump 2 is fixedly connected to the end of the pipe 201 away from the inner cylinder 52.

[0028] The bottom of the inner cylinder 52 is provided with a venting groove 54. When fixing the gearbox housing 3, the gearbox housing 3 is inserted into the positioning component 5. Then, the inner cylinder 52 is rotated so that the venting groove 54 and the pressure groove 55 are connected. Then, the air pump 2 is controlled to inject gas into the groove 501. The side wall of the outer cylinder 51 is provided with a pressure groove 55. The inside of the pressure groove 55 is slidably connected with a fixing plate 56. The opening position of the venting groove 54 corresponds one-to-one with the opening position of the pressure groove 55. As the gas is injected, the gas slowly rushes into the pressure groove 55. The gas pushes the fixing plate 56 to move out of the groove 501, so that it abuts against the inner side wall of the gearbox housing 3, thereby achieving the positioning effect.

[0029] When faced with gearbox housings 3 of different sizes, the device can accurately fix them, achieving precise positioning. This precise positioning significantly reduces positioning errors during the machining process. This helps ensure the dimensional and positional accuracy of machined holes, surfaces, and other parts, thereby improving the overall performance of the gearbox housing 3. For gearbox housings 3 of different sizes, the precise positioning device ensures they have the same or similar machining accuracy during processing, thus guaranteeing product consistency. It also significantly shortens the positioning and clamping time before machining, improving production efficiency. Accurate positioning also reduces machining errors and rework caused by inaccurate positioning, saving debugging time and costs.

[0030] A rotating handle 7 is fixedly connected to the top of the inner cylinder 52.

[0031] The bottom of the tooling table 1 is provided with a fixed slide groove 6, and the bottom of the inner cylinder 52 is provided with a fixed slot 53. A fixed block 61 is slidably connected inside the fixed slide groove 6. When the venting groove 54 and the pressure groove 55 are connected, the fixed block 61 is inserted into the fixed slot 53 to prevent the inner cylinder 52 from deflecting during the inflation process, thus achieving the effect of fixing the inner cylinder 52. When the gas pushes against the inner side wall of the gearbox housing 3, the positioning effect is achieved. First, rotate the inner cylinder 52 so that the fixed block 61 is engaged in the venting groove 54. At this time, the gas in the pressure groove 55 is blocked by the side wall of the inner cylinder 52, thus ensuring that the fixed plate 56 cannot move again, thereby achieving the positioning effect. A spring 62 is provided inside the fixed slide groove 6. The two ends of the spring 62 are fixedly connected to the fixed block 61 and the fixed slide groove 6, respectively. The fixed block 61 is engaged in the fixed slot 53.

[0032] A gearbox housing 3 is provided above the positioning component 5. The positioning component 5 is set inside the gearbox housing 3. A suction cup 57 is fixedly connected to the end of the fixing plate 56. The suction cup 57 abuts against the inner wall of the gearbox housing 3. The suction cup 57 is made of soft material, which can better fit the inner wall of the gearbox housing 3. In addition, the suction cup 57 also has a fixing effect, playing an auxiliary fixing role.

[0033] Working principle: When fixing the gearbox housing 3, the gearbox housing 3 is inserted into the positioning component 5. Then, the inner cylinder 52 is rotated to connect the vent groove 54 and the pressure groove 55. At this time, the fixing block 61 is inserted into the fixing slot 53 to prevent the inner cylinder 52 from deflecting during the inflation process. Then, the air pump 2 is controlled to inject gas into the groove 501. As the gas is injected, the gas slowly rushes into the pressure groove 55. The gas pushes the fixing plate 56 to move out of the groove 501, so that it drips onto the inner wall of the gearbox housing 3. After fixing, the inner cylinder 52 is rotated to make the fixing block 61 engage in the vent groove 54. At this time, the gas in the pressure groove 55 is blocked by the side wall of the inner cylinder 52, which ensures that the fixing plate 56 cannot move again, thereby achieving the positioning effect.

[0034] The above embodiments are only used to illustrate the technical methods 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 methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
