Description

Technical Field

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

[0002] The gearbox housing is a major component of a car's gearbox, providing protection and support for the core parts of the transmission. This component is typically made of metal and can withstand mechanical stress and temperature changes. The housing is designed with internal space to accommodate various critical components such as gears, shafts, and bearings, and also includes corresponding mounting positions. During the machining of the outer surface of the gearbox housing, a fixing and positioning device is generally required for its internal cavity.

[0003] During processing, the gearbox housing needs to be positioned. While existing positioning devices can quickly fix the gearbox housing, they have significant limitations in use, making it inconvenient to fix different models of gearbox housings. This necessitates the design of specific positioning devices for each model. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a positioning device for the inner cavity end face of the gearbox housing. This solves the technical problem that although the current positioning device can achieve rapid fixation of the gearbox housing, it has great limitations in use and is not convenient for fixing different models of gearbox housings, so that different models of gearbox housings need to be fixed by specific positioning devices.

[0005] To achieve the objective of this utility model, the technical solution adopted by this utility model is as follows: A positioning device for the inner cavity end face of a gearbox housing is designed, comprising: Processing table; A tensioning mechanism is provided on the surface of the processing table. The tensioning mechanism integrates a positioning mechanism. The positioning mechanism is moved by the tensioning mechanism to achieve positioning of the end face of the inner cavity of the gearbox housing. The positioning mechanism includes: A connecting plate has symmetrical connecting grooves at both ends. Each of the two connecting grooves is equipped with an extrusion assembly. Both ends of the extrusion assembly are fixedly connected to a connecting shaft, and the other end of the connecting shaft is rotatably connected to the inner wall of the connecting groove through a bearing. An arc-shaped groove is formed on the connecting plate and communicates with the inner cavity of the connecting groove; A first screw is fixedly connected to the end of the extrusion assembly near the arc shape. The first screw passes through the arc groove, and a first nut is threaded onto the outer side of the first screw above the arc groove.

[0006] Preferably, the tensioning mechanism includes: A mounting plate is provided on the surface of the processing table. A through hole is provided on the mounting plate, and a second screw is slidably connected in the through hole. A connecting plate is fixedly connected to the bottom of the second screw. The second nut is threaded onto the outside of the second screw.

[0007] Preferably, the extrusion assembly includes a first extrusion plate and a second extrusion plate. The second extrusion plate has a hollow structure and an opening at one end near the first extrusion plate. The second extrusion plate is slidably sleeved on the outside of the first extrusion plate. A lead screw is rotatably connected to the inner cavity of the second extrusion plate through a bearing. The lead screw rotatably passes through the first extrusion plate and is located on the outside of the first extrusion plate. The lead screw is threadedly connected to the first extrusion plate.

[0008] Preferably, the surface of the processing table is symmetrically provided with adjustment holes, the mounting plate is slidably connected in the adjustment holes, the two ends of the processing table are symmetrically provided with threaded holes, and the threaded holes are connected to the adjustment holes, and a third screw is threadedly connected in the threaded holes.

[0009] Preferably, a rubber pad is fixedly connected to the end of the second extrusion plate away from the first extrusion plate, and the rubber pad is elastic.

[0010] Preferably, an anti-slip pad is fixedly connected to one end of the mounting plate near the third screw, and the anti-slip pad is integrally molded from rubber material.

[0011] Preferably, the two ends of the perforated inner cavity are symmetrically fixedly connected with limiting blocks, and the two ends of the first screw are symmetrically provided with limiting grooves, and the limiting blocks are slidably connected in the limiting grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the arrangement of a tensioning mechanism, a positioning mechanism, and extrusion components, allows two extrusion components to move in opposite directions by rotating a nut. These extrusion components then contact the two end faces of the inner cavity of the gearbox housing, achieving tensioning and positioning of the gearbox housing. During positioning, rotating the first nut allows for angle adjustment of the symmetrically distributed extrusion components on both sides of the connecting plate. Once a suitable angle is reached, tightening the first nut fixes the adjusted angle of the extrusion components. This allows the extrusion components to be positioned appropriately against the inner cavity end face of the gearbox housing, enabling them to adapt to different models of gearbox housings and further avoiding limitations in positioning different models of gearbox housings caused by the fixed positioning mechanism.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: A positioning device for the inner cavity end face of a gearbox housing, see [link / reference] Figures 1 to 5 The system includes: a processing table 1; a tensioning mechanism disposed on the surface of the processing table 1, wherein a positioning mechanism 3 is integrated on the tensioning mechanism, and the positioning mechanism 3 is moved by the tensioning mechanism to achieve positioning of the end face of the inner cavity of the gearbox housing; the positioning mechanism 3 includes: a connecting plate 31, wherein connecting grooves 32 are symmetrically opened at both ends, and each of the two connecting grooves 32 is provided with a pressing component, wherein both ends of the pressing component are fixedly connected to a connecting shaft 33, and the other end of the connecting shaft 33 is rotatably connected to the inner wall of the connecting groove 32 through a bearing; and an arc-shaped groove 4 opened on the connecting plate 31. The first screw 41 is fixedly connected to the end of the extrusion assembly near the arc shape, and the first screw 41 passes through the arc groove 4. A first nut 42 is threaded on the outer side of the first screw 41 above the arc groove 4. The tensioning mechanism includes: a mounting plate 2, which is disposed on the surface of the processing table 1. A through hole 25 is provided on the mounting plate 2. A second screw 22 is slidably connected in the through hole 25. The connecting plate 31 is fixedly connected to the bottom of the second screw 22. A second nut 23 is threaded on the outer side of the second screw 22.

[0016] During operation, the positioning mechanism 3 is placed inside the gearbox housing. By rotating the nut, the two pressing components can be moved in opposite directions. The two pressing components contact the two end faces of the gearbox housing, thereby tightening and positioning the gearbox housing. During positioning, the angle of the pressing components symmetrically distributed on both sides of the connecting plate 31 can be adjusted by rotating the first nut 42. When the appropriate angle is reached, the angle of the pressing components is fixed by tightening the first nut 42. This allows the pressing components to be adjusted to correspond to the suitable positioning position of the end face of the gearbox housing cavity, enabling the pressing components to adapt to the end face of the gearbox housing cavity of different models. This further avoids the limitation of positioning different models of gearbox housings due to the fixation of the positioning mechanism 3.

[0017] For details, see Figure 2 and Figure 3 The extrusion assembly includes a first extrusion plate 34 and a second extrusion plate 35. The second extrusion plate 35 has a hollow structure and an opening at one end near the first extrusion plate 34. The second extrusion plate 35 is slidably sleeved on the outside of the first extrusion plate 34. A lead screw 5 is rotatably connected to the inner cavity of the second extrusion plate 35 through a bearing. The lead screw 5 rotatably passes through the first extrusion plate 34 and is located on the outside of the first extrusion plate 34. The lead screw 5 is threadedly connected to the first extrusion plate 34. By rotating the lead screw 5, the length of the connection between the first extrusion plate 34 and the second extrusion plate 35 can be adjusted, thereby independently adjusting the overall length of the extrusion assembly on both sides of the same connecting plate 31. This ensures the stability of the extrusion assembly with the inner cavity end face of the gearbox housing, allowing the extrusion assembly to adapt to various types of gearbox housings and further expanding the applicability of the positioning mechanism 3.

[0018] Further, see Figure 4 The surface of the processing table 1 is symmetrically provided with adjustment holes 6. The mounting plate 2 is slidably connected in the adjustment holes 6. The two ends of the processing table 1 are symmetrically provided with threaded holes 61, and the threaded holes 61 are connected to the adjustment holes 6. A third screw 62 is threadedly connected in the threaded holes 61. The mounting plate 2 can slide laterally along the adjustment holes 6. By rotating the third screw 62, the position of the mounting plate 2 is locked through the friction between the mounting plates 2. It can accurately align the inner cavity center of different models of housings, avoid the positioning deviation problem caused by the different depths of the housings in fixing the mounting holes, and realize the processing needs of multiple specifications of gearboxes with one device.

[0019] It is worth noting that, see Figure 2…A rubber pad 36 is fixedly connected to the end of the second extrusion plate 35 away from the first extrusion plate 34, and the rubber pad 36 is elastic. By setting the rubber pad 36, not only is wear caused by the second extrusion plate 35 directly contacting the end face of the inner cavity of the gearbox housing, but the friction between the second extrusion plate 35 and the end face of the inner cavity of the gearbox housing is also increased, further improving the firmness of the gearbox housing positioning.

[0020] It is worth noting that, see Figure 5 An anti-slip pad 64 is fixedly connected to one end of the mounting plate 2 near the third screw 62. The anti-slip pad 64 is integrally formed from rubber material. By setting the anti-slip pad 64, the friction between the end face of the third screw 62 and the mounting plate 2 is increased, thereby further improving the stability of the positioning of the mounting plate 2.

[0021] It is worth mentioning that, see Figure 1 and Figure 5 The inner cavity of the perforation 25 is symmetrically fixedly connected to the two ends of the limiting block 24. The two ends of the first screw 41 are symmetrically provided with limiting grooves 21. The limiting block 24 is slidably connected in the limiting groove 21. Through the cooperation of the limiting block 24 and the limiting groove 21, the movement of the first screw 41 is guided, so as to avoid the first screw 41 rotating and causing the extrusion component to be unable to accurately correspond to the positioning position of the end face of the inner cavity of the gearbox housing.

[0022] The first screw 41, the second screw 22, the third screw 62, and the lead screw 5 are all fitted with rubber telescopic tubes on their outer sides to protect them and prevent impurities from getting stuck on their outer sides and affecting normal rotation.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
