[0002] With the improvement of people's requirements for product processing quality and quality, as well as people's yearning for a green ecological environment, labor costs have increased accordingly. Modern concepts such as the traceability of product problems have higher and higher requirements for equipment. Therefore, the processing costs that enterprises need to spend are getting higher and higher. In order to save labor costs and time costs, this undoubtedly puts forward higher requirements for production efficiency.

[0003] In the machining process of the axle housing reducer assembly, the fixture that matches it during automatic loading and unloading must clamp the product. However, how to define whether the product fits the positioning surface of the fixture and whether the positioning is reliable. The traditional method is that a product of one model corresponds to a positioning disk to connect with the fixture. When it is necessary to replace products of different models or different products, the corresponding positioning disk needs to be replaced, and then rinsed and assembled, which is time-consuming, laborious and costly. Content of the Utility Model

[0010] As a further technical solution, a second sealing washer is provided on the positioning disc, and the second sealing washer is provided at one end of the second connection hole communicating with the end face positioning block.

[0011] As a further technical solution, the air inlet hole is connected to an airtightness detection device through a ventilation pipe.

[0012] As a further technical solution, the clamping element is hinge-type, and the pressing plate on the clamping element presses the product onto the positioning disc.

[0013] As a further technical solution, the connecting piece is a flexible hose.

[0014] The beneficial effects of the present utility model are as follows: air is introduced through the air inlet hole to the air outlet hole to detect whether the airtightness between the product and the end face positioning block meets the requirements, improving the stability and reliability of the product positioning by the fixture, and reducing the difficulty of fixture manufacturing;

[0015] In addition, in the present utility model, the first through hole, the second through hole, and the connecting piece are connected to the fixture body in a way to achieve the flexibility of the fixture;

[0029] To solve the problems in the prior art that the corresponding positioning disk 3 needs to be replaced and re-assembled for the processing of different products, this embodiment provides a tooling fixture. Refer to Figures 1 - 5 , including a fixture body 1, a clamping element 2, a positioning disk 3, and a connecting member 4;

[0030] The positioning disk 3 is provided on one end face of the fixture body 1. Both ends of the connecting member 4 are respectively inserted into a first through hole 31 and a second through hole 32 on the positioning disk 3. An air inlet hole 11 on the fixture body 1 is communicated with the first through hole 31. An air outlet hole 331 communicated with the second through hole 32 is provided on an end face positioning block 33 on the positioning disk 3, so that gas sequentially passes through the air inlet hole 11, the first through hole 31, the second through hole 32, and the air outlet hole 331 to detect the air pressure value between the end face positioning block 33 and the product joint surface. The clamping element 2 is provided on the fixture body 1 and acts above the product positioning surface, so that the end face positioning block 33 is attached to the product positioning surface without loosening. After the air pressure value is qualified, the product can be placed into a specified station for processing, and the product is unloaded after the fixture returns to the loading station; when different processed products need to be replaced, the positioning disk 3 is disassembled and a new positioning disk is replaced. The size of the positioning disk changes with the size of the product. Since the gas path is penetrated through the first through hole 31 and the second through hole 32, it will not be affected by the fixed air inlet hole 11 on the fixture body 1, realizing the flexibility of the fixture. Preferably, the air inlet hole 11 is connected to an airtightness detection device through an air pipe 5, and a first pipe joint 6 is provided on one side where the air pipe 5 is communicated with the air inlet hole 11; the connecting member 4 is preferably a hose, and second pipe joints 7 are provided at the communication positions between the hose and the first through hole 31 and the second through hole 32.

[0031] In the specific implementation process, referring to Figure 2 , to strengthen the airtightness, a first sealing washer 12 is provided on the fixture body 1, and the first sealing washer 12 is provided at one end of the air inlet hole 11 communicated with the positioning disk 3.

[0032] In the specific implementation process, for the smooth flow of gas, referring to Figure 2 、 Figure 4 、 Figure 5 , a first connecting air hole 34 with both ends respectively communicated with the air inlet hole 11 and the first through hole 31 is further opened on the positioning disk 3; a second connecting air hole 35 with both ends respectively communicated with the second through hole 32 and the air outlet hole 331 is further opened on the positioning disk 3. Correspondingly, a second sealing washer 36 is provided on the positioning disk 3, and the second sealing washer 36 is provided at one end of the second connecting air hole 35 communicated with the end face positioning block 33.

[0033] In the specific implementation process, referring to Figure 1 , the clamping element 2 is of a hinge type, and a pressing plate 21 on the clamping element 2 presses the product on the positioning disk 3.

[0034] It can be realized that: referring to Figure 1, in this embodiment, there are four clamping elements 2, the positioning disks 3 are two symmetrical arc-shaped structures, and two of the clamping elements 2 are symmetrically arranged on each positioning disk 3.

[0035] The present utility model is implemented as follows:

[0036] 1. Loading: Fit the positioning disk 3 onto the fixture body 1 so that the first connection hole communicates with the first through hole 31; then connect the two ends of the connecting piece 4 to the second pipe joint 7 respectively, insert them into the first through hole 31 and the second through hole 32, place the product on the positioning disk 3 and clamp and position it through the clamping element 2;

[0037] 2. Ventilation: Vent air into the fixture body 1 (the airtightness detection device can be turned on here), and judge whether the fit degree between the end face positioning block 33 and the product meets the requirements (that is, whether the gap between the two exceeds the standard) through the air pressure value;

[0038] 3. Continuously adjust the gas volume until the detection is qualified, and then put the fixture with the product into the designated station for processing;

[0039] 4. Unloading: After processing, the fixture returns to the loading station and unloads the material;

[0040] 5. When different products need to be replaced, repeat steps 1-3 until the ventilation meets the requirements, and then subsequent processing work can be carried out.

[0041] It should be noted that in the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0042] Although the preferred embodiments of the present utility model have been described, those skilled in the art can make additional changes and modifications to these embodiments once they know the basic creative concept. Therefore, the appended claims are intended to be construed as including the preferred embodiments and all changes and modifications falling within the scope of the present utility model.

[0043] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
