Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to a positioning fixture for the bonding process of automatic gearbox partition plates. Background Technology

[0002] Automatic transmission partitions, often simply called transmission dividers or baffles, are crucial components within the transmission. Their primary function is to connect and separate the oil passages of the upper and lower valve plates. The partitions also feature numerous throttling orifices for regulating pressure and flow. Partitions are typically composed of a rubber fiber composite material bonded to a metal surface, providing a stronger seal compared to a metal surface. They are widely used in various types of automatic transmissions. The production of automatic transmission partitions involves assembling multiple parts using a high-temperature, high-pressure bonding process. The acrylic adhesive applied to the composite material is non-adhesive at room temperature but develops its properties under high temperature and pressure, bonding tightly to the metal surface. Currently, the bonding process for these multiple partition parts involves manual assembly followed by direct placement into a hot press for high-temperature, high-pressure bonding. However, without proper positioning of the multiple parts, misalignment can easily occur during bonding, and adjacent parts may not adhere tightly, resulting in poor-quality partitions or even a low yield rate. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a positioning fixture for the bonding process of automatic transmission partition plates, so as to solve the problem of poor quality of partition plate manufacturing in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides a positioning fixture for the bonding process of automatic transmission partition plates, including a base, the base including a lower positioning base surface, the lower positioning base surface having a plurality of upwardly protruding positioning pins, and the lower positioning base surface also having a plurality of downwardly protruding positioning portions; a cover plate, the cover plate including an upper positioning base surface, the upper positioning base surface having a plurality of positioning holes, the positions of the plurality of positioning holes corresponding one-to-one with the positions of the plurality of positioning pins, and the upper positioning base surface also having a plurality of upwardly protruding positioning portions.

[0005] Furthermore, handles are provided on the left and right sides of the cover plate respectively.

[0006] Furthermore, the cross-section of the positioning pin gradually decreases from bottom to top.

[0007] Furthermore, the base is provided with a plurality of upwardly extending guide posts, and the cover plate is provided with a plurality of guide holes corresponding to the guide posts.

[0008] As described above, the positioning fixture of this utility model for the bonding process of automatic transmission partition plates has the following beneficial effects: the positioning fixture of this utility model can achieve the positioning of multiple pieces of material laid and stacked during the high temperature and high pressure bonding process of the partition plate, thereby preventing the multiple pieces of material from shifting or misaligning. Moreover, the multiple pieces of material are clamped between the base and the cover plate, which can also make the two adjacent pieces of material bond more tightly, thereby greatly improving the quality of partition plate manufacturing.

[0025] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] Please see Figure 1 and Figure 2 It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0027] This utility model provides a positioning fixture (hereinafter referred to as "positioning fixture") for the bonding process of automatic transmission partition plates, such as... Figure 1 and Figure 2 As shown, the positioning fixture includes a base 10 and a cover plate 20. The base 10 includes a lower positioning base surface 101, on which a plurality of upwardly protruding positioning pins 11 are provided, and a plurality of downwardly protruding positioning portions 12 are also provided on the lower positioning base surface 101. The cover plate 20 includes an upper positioning base surface 201, on which a plurality of positioning holes 21 are provided. The positions of the plurality of positioning holes 21 correspond one-to-one with the positions of the plurality of positioning pins 11 provided on the base 10, and a plurality of upwardly protruding positioning portions 22 are provided on the upper positioning base surface 201.

[0028] The beneficial effects of this utility model for the positioning fixture in the bonding process of automatic transmission partition plates are as follows: During the high-temperature and high-pressure bonding process of the partition plates, multiple pieces of material are first laid layer by layer on the base 10, so that multiple positioning pins 11 on the base 10 are embedded in the positioning holes of each piece of material. Considering that the lowest layer of material generally has a groove, a lower protruding positioning part 12 is provided on the base 10. When laying the lowest layer of material, the lower protruding positioning part 12 passes through the groove in the lowest layer of material, so that the lower protruding positioning part 12 is aligned with the groove in the lowest layer of material. The upper layer of material contacts each other, thus making the force on the multi-layer material more uniform. After the multiple materials are laid and stacked, the cover plate 20 is placed on top of the multiple materials, and the multiple positioning pins 11 on the base 10 are inserted into the corresponding positioning holes 21 on the cover plate 20. Also, considering that the top layer of material usually has a groove, a protruding positioning part 22 is provided on the cover plate 20, so that the protruding positioning part 22 passes through the groove on the top layer of material and contacts the lower layer of material, thereby improving the uniformity of the force on the multi-layer material. After the cover plate 20 is in place, the entire positioning fixture is sent into the hot press. The entire positioning fixture is subjected to high temperature and high pressure. During the high temperature and high pressure bonding process in the hot press, the positioning pins 11 can be used to position the multiple pieces of material that are laid and stacked, thereby preventing the multiple pieces of material from shifting or misaligning. The multiple pieces of material are clamped between the base and the cover plate, which also makes the two adjacent pieces of material fit more tightly, thereby greatly improving the quality of the partition board manufacturing.

[0029] Specifically, it should be noted that the shape of the lower positioning protrusion 12 on the base 10 and the shape of the upper positioning protrusion 22 on the cover plate 20 can be specifically designed according to the shape and structure of the groove on the material.

[0030] Furthermore, such as Figure 2 As shown, in order to facilitate the taking and putting away of the cover plate 20, in this embodiment, handles 24 are provided on the left and right sides of the cover plate 20 respectively.

[0031] Furthermore, to improve the ease of laying materials on the base, i.e., the lower positioning base 101, preferably, in this embodiment, the positioning pin 11 is tapered, meaning the cross-section of the positioning pin 11 gradually decreases from bottom to top. With this structural design, because the cross-section of the positioning pin 11 gradually decreases from bottom to top—that is, the upper cross-section of the positioning pin 11 is smaller and the lower cross-section is larger—the upper part of the positioning pin 11 serves as a guide. Therefore, when laying materials on the lower positioning base 101, the positioning holes on the material can easily fit onto the positioning pin, greatly improving the efficiency of laying and stacking multiple layers of material on the base.

[0032] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the base 10 is provided with a plurality of upwardly extending guide posts 13, and correspondingly, the cover plate 20 is provided with a plurality of guide holes 23 corresponding to the plurality of guide posts 13. That is, the positions of the plurality of guide holes 23 on the cover plate 20 correspond one-to-one with the positions of the plurality of guide posts 13 on the base 10. With this design, when the cover plate 20 is placed on, the plurality of guide holes 23 on the cover plate 20 and the plurality of guide posts 13 on the base 10 respectively engage one-to-one. Thus, when the cover plate 20 is placed on, the guide posts 13 guide the positioning pins 11 on the base 10 to engage perfectly with the positioning holes 21 on the cover plate 20, improving the fit accuracy between the cover plate and the base, thereby improving the positioning accuracy of multiple materials and improving the quality of the partition plate manufacturing.

[0033] On the other hand, when the positioning fixture is not used for a long time, a washer can be fitted on each of the guide columns to make a certain gap between the base 10 and the cover plate 20, so as to avoid the base 10 and the cover plate 20 from sticking together and being difficult to separate due to long-term stacking.

[0034] Specifically, such as Figure 1 As shown, in this embodiment, three guide posts 13 are provided, and the three guide posts 13 are respectively arranged on the three sides of the base 10, so that the three guide posts 13 form a triangle. Correspondingly, guide holes 23 corresponding to the guide posts 13 are provided on the three sides of the cover plate 20. In this way, the stability of positioning can be improved.

[0035] In summary, the positioning fixture of this invention for the bonding process of automatic transmission partition plates enables the positioning of multiple stacked materials during the high-temperature and high-pressure bonding process. This prevents the stacked materials from shifting or misaligning, and the clamping of the stacked materials between the base and the cover plate ensures a tighter bond between adjacent materials, thus significantly improving the quality of partition plate manufacturing. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial applicability.

[0036] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
