Description

Technical Field

[0001] The utility model relates to the technical field of single-part size detection, in particular to a sliding multifunctional detection fixture. Background Art

[0002] Metal injection molding (MIM) is a new forming technology that has developed rapidly internationally in recent years. Its advantage is that it is suitable for mass production of metal parts with precision, complex three-dimensional shapes and special performance requirements. The products formed and sintered by it not only have the same complex shape and high precision as the products obtained by plastic injection molding, but also have physical, chemical and mechanical properties close to those of forgings.

[0003] The general process is: mix the selected powder with the binder, then granulate the feed and inject it into the required shape. After forming, remove the binder and sinter the defatted powder. Sintering is a high-temperature treatment process that strengthens and densifies the formed powder blank, which directly affects the quality of the product.

[0004] Due to the influence of factors such as heating rate, sintering temperature and time, cooling rate, sintering atmosphere and sintering pressure conditions during the sintering process, sintered parts will have adverse reactions such as dimensional deviation and deformation.

[0005] For parts with high precision requirements, if the product does not meet the size requirements, it will be impossible to install, get stuck or loose after installation, etc. Although the existing fixtures can solve the problem of identifying defective products, due to the large number of products and the slow detection efficiency of the three-dimensional coordinate measuring machine, it is impossible to achieve mass production and cannot perform stable production well.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1:

[0028] See also Figure 1-6 The utility model provides a technical solution: a sliding multifunctional detection fixture, including: a bottom plate fixing plate 1, a PIN gauge detection block 2, a guide fixing plate 3, a guide column 4, an arc detection block 5, a fast pressing head device 7, a positioning pin 8, a fixing seat 9, and a pressing head fixing seat 10;

[0029] The guide fixing plate 3 is fixedly connected to the left side of the upper surface of the bottom plate fixing plate 1, the guide column 4 is connected to the side wall of the guide fixing plate 3, the arc detection block 5 is slidably connected to the guide column 4, and the PIN gauge detection block 2 is slidably plugged on the guide fixing plate 3; the fixing seat 9 and the pressure head fixing seat 10 are installed in the middle and right side of the upper surface of the bottom plate fixing plate 1, the fixing seat 9 is used to install the part itself 6, and the pressure head fixing seat 10 is provided with a fast pressure head device 7. The arc detection block 5 is provided with an arc track groove.

[0030] Analysis of the above content: When in use, the part itself 6 is placed on the fixing seat 9, and the fixing seat 9 is set to a shape that matches the part itself 6. After the part itself 6 is clamped on the fixing seat 9, the part itself 6 is not easy to move. Then the quick pressing head device 7 is folded downward so that the quick pressing head device 7 is pressed tightly on the part itself 6, and the part itself 6 will be completely fixed.

[0031] Push the PIN gauge detection block 2 on the guide fixing plate 3 toward the part itself 6 until the PIN gauge detection block 2 contacts the part itself 6, and read the reading of the PIN gauge detection block 2. When the reading is not within the qualified size range, it is considered that the size of the part itself 6 is inaccurate (the qualified size range is pre-set for comparison).

[0032] Slide the arc detection block 5 so that the arc track groove of the arc detection block 5 passes through the arc structure of the part itself 6. When the position of the arc structure of the part itself 6 and the arc track groove do not correspond, the arc track groove cannot slide through the arc structure of the part itself 6. This means that the arc structure size or arc of the part itself 6 does not meet the requirements.

[0033] Embodiment 2:

[0034] See also Figure 1-6 The utility model provides a technical solution based on the first embodiment: the guide pillar 4 is cylindrical, two guide pillars 4 are provided, and the two guide pillars 4 are parallel to each other.

[0035] Analysis of the above content: In order to keep the arc detection block 5 sliding smoothly without rotating relative to the guide pillar 4, two guide pillars 4 are set so that the arc detection block 5 can slide smoothly.

[0036] Alternatively, the guide post 4 may be in the shape of a polygonal column, so that the arc detection block 5 cannot rotate relative to the guide post 4 due to the shape of the guide post 4 .

[0037] Embodiment three:

[0038] See also Figure 1-6 The utility model provides a technical solution based on the first embodiment: a positioning pin 8 is longitudinally inserted on the fixing seat 9, the bottom end of the positioning pin 8 is inserted on the bottom plate fixing plate 1, the positioning pin 8 protrudes to the upper surface of the fixing seat 9, and a positioning hole matching the positioning pin 8 is provided on the part itself 6.

[0039] Analysis of the above content: By inserting the positioning pin 8 into the positioning hole of the component itself 6, the component itself 6 is initially installed on the fixing seat 9 to be more stable.

[0040] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
