Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and more specifically, to an airtight fixture for turning the front housing of a differential. Background Technology

[0002] During the machining of the differential front housing, such as in turning, a fixture is used to fix the position of the differential front housing to ensure stable machining and prevent movement that could lead to machining deviations. However, existing fixtures use an internal expansion positioning method. In this method, the distance from the internal expansion positioning to the edge is too far, resulting in slight deformation of the part during tightening and causing errors. This leads to deviations in subsequent machining, resulting in a decrease in part quality. To solve this problem, the fixture needs to be improved. Therefore, we propose an airtight fixture for turning the differential front housing. Utility Model Content

[0003] The main purpose of this invention is to provide an airtight fixture for turning the front housing of a differential, which can effectively solve the problem that slight changes occur when the existing fixture is used to fix the front housing of the differential, thus affecting the machining process.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A gas-tight fixture for turning the front housing of a differential includes a base. The upper surface of the base has several sets of first screw holes. A positioning component for defining the position of the product housing is installed on the upper side of each first screw hole by bolts. A fixing component for fixing the product housing is installed between every two sets of first screw holes. The product housing is located inside the positioning component. A connecting seat is fixedly installed at the lower end of the base.

[0006] Preferably, the fixing components are provided in three equally distributed on the upper surface of the base. Each fixing component includes an adjustment groove, which is inclined. An adjustment seat is installed inside the adjustment groove, and a clamping block for holding the product shell is provided on the upper side of the adjustment seat.

[0007] Preferably, the clamping block has a plurality of second through holes inside, and the adjusting seat has a plurality of second screw holes inside. Bolts are installed inside the second through holes and the bolts are threadedly engaged with the adjacent second screw holes.

[0008] Preferably, the positioning component includes a positioning fixture disk, the outer side of which is provided with a plurality of first through holes, and bolts are provided inside the first through holes and the bolts are threadedly engaged with adjacent first screw holes, and the product housing is located inside the positioning fixture disk.

[0009] Preferably, the positioning fixture disk has a mounting hole in the middle, and a positioning mandrel is installed inside the mounting hole, with the positioning mandrel aligned with the center of the product housing.

[0010] Preferably, the lower end of the positioning fixture disk is provided with a combination seat, which is aligned with the center of the base.

[0011] Preferably, the outer side of the positioning fixture disk is provided with a number of airtight holes, and a first connecting hole is connected in series between every two adjacent airtight holes. A second connecting hole is provided in the middle of the first connecting hole, and the second connecting holes are connected in series with a lower through hole at the connection point.

[0012] Preferably, the upper side of the inner wall of the positioning fixture disk is provided with an anti-misoperation slot.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) By adjusting the groove to be inclined, the distance between the clamping block and the center of the base can be adjusted when the adjusting seat is adjusted up and down, so that the clamping block can adaptively clamp the product shell. There are three sets of fixing components. After adjusting the clamping block, the product shell is clamped to ensure stable clamping. By changing the clamping position from the inner expansion of the center to the outer circle, the slight deformation of the parts can be reduced, thus avoiding affecting the quality. The anti-error slot can only clamp in one direction, which can ensure that the product shell is in the correct direction when stored in the positioning fixture plate. This makes the fixture of this application have an anti-error function, which is more convenient for personnel to clamp and reduces clamping time.

[0015] (2) The combination seat can ensure that the positioning fixture plate is aligned with the base during assembly, avoiding positional deviation after the product housing is clamped. The positioning mandrel can also ensure that the product housing is aligned when it is stored in the positioning fixture plate. The above structure can achieve the alignment of the positioning fixture plate, the product housing and the base. The above structure, together with the fixing components, can quickly fix the product housing and reduce clamping time.

[0016] (3) The lower through hole, the second connecting hole, the first connecting hole and each airtight hole are interconnected, which facilitates personnel to perform multi-hole inspection. Among them, multiple airtight holes can be used to check whether the parts are clamped and balanced. Compared with the existing fixtures, this application can use multiple airtight holes to check after clamping to ensure that the product shell is clamped in place and reduce clamping errors, thereby avoiding deviations in subsequent processing and improving product quality.

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0028] like Figures 1 to 9 As shown, the airtight fixture for turning the front housing of the differential includes a base 1. Several sets of first screw holes 7 are opened on the upper surface of the base 1. A positioning component 2 for defining the position of the product housing 4 is installed on the upper side of each first screw hole 7 by bolts. A fixing component 3 for fixing the product housing 4 is installed between every two sets of first screw holes 7. The product housing 4 is located inside the positioning component 2. A connecting seat 5 is fixedly installed at the lower end of the base 1.

[0029] In this embodiment, three fixing components 3 are provided and are evenly distributed on the upper surface of the base 1. The fixing components 3 include an adjustment groove 301, which is inclined. An adjustment seat 302 is installed inside the adjustment groove 301. A clamping block 303 for clamping the product housing 4 is provided on the upper side of the adjustment seat 302.

[0030] The clamping block 303 has several second through holes 304 inside, and the adjusting seat 302 has several second screw holes 305 inside. The second through holes 304 are provided with bolts and the bolts are threadedly engaged with the adjacent second screw holes 305.

[0031] By adjusting the groove 301 to be inclined, the distance between the clamping block 303 and the center of the base 1 can be adjusted when the adjusting seat 302 is adjusted up and down. This allows the clamping block 303 to adaptively clamp the product housing 4. The fixing component 3 is provided with three sets. After adjusting the clamping block 303, the product housing 4 is clamped to ensure stable clamping. By changing the clamping position from the inner center to the outer circle, the slight deformation of the parts can be reduced, thus avoiding affecting the quality.

[0032] In this embodiment, the positioning component 2 includes a positioning fixture disk 201. The positioning fixture disk 201 has several first through holes 202 on its outer side. Bolts are provided inside the first through holes 202 and the bolts are threadedly engaged with the adjacent first screw holes 7. The product housing 4 is located inside the positioning fixture disk 201.

[0033] The positioning fixture disk 201 has a mounting hole 205 in the middle, and a positioning mandrel 6 is installed inside the mounting hole 205. The positioning mandrel 6 is aligned with the center of the product housing 4.

[0034] The positioning fixture disk 201 has a combination seat 206 at its lower end, which is aligned with the center of the base 1.

[0035] The combination seat 206 ensures that the positioning fixture plate 201 is aligned with the base 1 during assembly, preventing positional deviations after the product housing 4 is clamped. The positioning mandrel 6 ensures that the product housing 4 is also aligned when it is placed in the positioning fixture plate 201. The above structure enables the positioning fixture plate 201, the product housing 4, and the base 1 to be aligned. The above structure, together with the fixing component 3, enables the product housing 4 to be quickly fixed, reducing clamping time.

[0036] In this embodiment, the outer side of the positioning fixture disk 201 is provided with several sets of airtight holes 204. A first connecting hole 2041 is connected in series between every two adjacent airtight holes 204. A second connecting hole 2042 is provided in the middle of the first connecting hole 2041. The second connecting holes 2042 are connected in series and a lower through hole 2043 is provided at the connection point. The lower through hole 2043, the second connecting hole 2042, the first connecting hole 2041 and each airtight hole 204 are interconnected, which facilitates personnel to perform multi-hole inspection. The multiple airtight holes 204 can be used to check whether the part is clamped and balanced. Compared with the existing fixtures, this application can use multiple airtight holes 204 to check after clamping to ensure that the product shell 4 is clamped in place, reduce clamping errors, and thus avoid deviations in subsequent processing and improve product quality.

[0037] In this embodiment, an anti-mistake slot 203 is provided on the upper side of the inner wall of the positioning fixture disk 201. The anti-mistake slot 203 allows clamping in only one direction, which can ensure that the product housing 4 is in the correct orientation when stored in the positioning fixture disk 201. This makes the fixture of this application have an anti-mistake function, making it easier for personnel to clamp and reducing clamping time.

[0038] Working principle of the airtight fixture for machining the front housing of the differential:

[0039] In use, the product housing 4 is first placed into the positioning jig disk 201, where the positioning spindle 6 is positioned and engaged with the product housing 4, eliminating the need for manual alignment. During this process, three clamping blocks 303 are used to clamp the outer circle of the product housing 4, and the positioning jig disk 201 enables quick clamping of the product housing 4. After clamping, the sealing detection device is connected to the corresponding second connecting hole 2042 to detect the airtight hole 204 at the corresponding position, thereby ensuring that the clamping position of the product housing 4 is in place.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
