Description

Technical Field

[0001] This utility model patent relates to the field of parts processing, and in particular to a tooling for processing MIM parts. Background Technology

[0002] Metal powder injection molding (MIM) technology, a novel technology deeply integrating plastic injection molding and powder metallurgy, has been widely applied in various fields such as electronics, automobiles, and medical devices due to its significant advantages in mass production of miniaturized, high-precision, and complex-structured metal parts. Among these applications, metal parts with unique structures, such as electronic device trays, which require high dimensional accuracy and structural complexity, are typical targets for MIM technology. These parts manufactured using MIM technology are collectively referred to as MIM parts.

[0003] In the actual production process of MIM parts, due to the functional requirements and assembly precision requirements of the final product, after being formed by the MIM process, they usually need to undergo subsequent secondary processing steps such as welding, grinding, and drilling to meet the final performance requirements of the product. However, existing MIM parts are characterized by their diverse types and irregular shapes, which makes it difficult to use conventional fixing methods to stably and reliably position and install MIM parts during secondary processing. Utility Model Content

[0004] In order to achieve the positioning and installation of MIM parts, this utility model patent provides a tooling for processing MIM parts.

[0005] This utility model patent provides a tooling solution for machining MIM parts, which adopts the following technical solution:

[0006] A tooling for machining MIM parts includes a carrier plate having at least one positioning groove for placing the MIM part, a cover plate having at least a partial projection that coincides with the projection of the MIM part in the positioning groove, a through hole for the head of the MIM part to extend into, and the cover plate being fixed to the carrier plate by a fastener.

[0007] By adopting the above technical solution, when processing MIM parts, the MIM parts are installed in the positioning groove, and then the cover plate is placed on the MIM parts. At the same time, the head of the MIM parts is inserted into the through hole, and finally the fastener is locked. This allows for convenient and quick positioning and installation of the MIM parts.

[0008] Optionally, the bottom wall of the positioning groove protrudes partially towards the top wall of the carrier plate to form a positioning boss on the bottom wall of the groove.

[0009] By adopting the above technical solution, the positioning boss is used to support the MIM part to adapt to the bottom installation of the MIM part.

[0010] Optionally, the positioning groove has a receiving notch on its sidewall, the receiving notch extending away from the center line of the positioning groove, the receiving notch being used for the insertion of the corner protrusion of the MIM part;

[0011] And / or the positioning groove wall is provided with at least one clearance notch, the clearance notch extends away from the center line of the positioning groove, and the clearance notch is provided corresponding to the corner of the MIM part.

[0012] By adopting the above technical solution, the accommodating notch facilitates the installation of the protrusion of the MIM part; in addition, after the MIM part is processed, in order to facilitate the removal of the MIM part, the worker can use a jig to remove the MIM part from the positioning groove through the clearance notch.

[0013] Optionally, the through hole has a conformal notch on its wall for inserting MIM protrusions.

[0014] By adopting the above technical solution, the conformal notch is to facilitate the mounting of the protrusion of the MIM component.

[0015] Optionally, the top wall of the cover plate has at least one through-hole, which penetrates two opposite sides of the cover plate. The fastener includes multiple locking elements, and the through-hole is located between two adjacent locking elements.

[0016] By adopting the above technical solution, when locking the MIM part, due to the small size of the MIM part and the high assembly precision requirements, as well as the manufacturing tolerances in the machining of the through holes on the cover plate and the positioning grooves on the carrier plate, there will also be assembly tolerances when installing the cover plate. The superposition of manufacturing tolerances and assembly tolerances makes the cover plate difficult to install. Therefore, a through notch is made in the cover plate. The through notch can be used to divide the cover plate into multiple interconnected small cover plates, reducing the strength of the cover plate and making it easier for workers to fit all the through holes on the cover plate onto the head of the MIM part. While reducing the strength of the cover plate, it is necessary to fix multiple interconnected small cover plates at the same time. Therefore, multiple locking parts are used to fix the corresponding small cover plates to improve the stability of the cover plate.

[0017] Optionally, the carrier plate has at least two locating pins, and the cover plate has pin holes into which the locating pins are inserted.

[0018] By adopting the above technical solution, the locating pin is inserted into the pin hole to facilitate the pre-positioning of the cover plate and the subsequent locking of the cover plate.

[0019] Optionally, the carrier plate has a support platform on the side away from the cover plate, the support platform has a pin, and the carrier plate has a mounting hole for inserting the pin;

[0020] It also includes a cylinder, on which a gripper is hinged to the piston rod, and on which a swing rod is hinged to the gripper, and the swing rod is rotatably connected to the cylinder body.

[0021] By adopting the above technical solution, when installing the support, the pin is inserted into the mounting hole, and at the same time, the cylinder pushes out the gripper, which rotates around the swing rod, thereby clamping the support.

[0022] Optionally, the support platform is provided with a plurality of pads, the pads are arranged along the height direction of the support platform, and the carrier plate is arranged on the pads.

[0023] By adopting the above technical solution, since a large amount of debris is generated during the processing of MIM parts, the carrier plate is raised by the pad on the support platform, making it easier for workers to clean the carrier plate with a spray gun.

[0024] Optionally, the support platform has a support base on the side away from the carrier plate, the support platform has multiple connection holes, the support base is provided with a support column, and the support column is connected to the connection holes.

[0025] By adopting the above technical solution, the corresponding connection holes can be selected to connect with the support base according to the shape of the support platform, so as to increase the adaptability of the support base or the support platform.

[0026] In summary, this utility model patent includes at least one of the following beneficial technical effects: when processing MIM parts, the MIM parts are installed in the positioning groove, then the cover plate is placed on the MIM parts, and the head of the MIM parts is inserted into the through hole. Finally, the fixing member is locked, which can facilitate the positioning and installation of MIM parts. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-5 This utility model patent will be described in further detail.

[0034] This utility model patent embodiment discloses a tooling for machining MIM parts.

[0035] like Figure 1-5 A tooling for machining MIM parts includes a carrier plate 2, which has at least one positioning groove 3 for placing MIM parts 1. The bottom wall of the positioning groove 3 has a through hole 4 for easy chip removal.

[0036] Since the bottom of the MIM part 1 has four support parts 5, and there is a height difference between two support parts 5 and the other two support parts 5, a positioning boss 6 is formed on the bottom wall of the positioning groove 3 and protrudes partially towards the top wall of the carrier plate 2. The positioning boss 6 and the bottom wall of the positioning groove 3 are formed with a height difference, so that the positioning boss 6 and the bottom wall of the positioning groove 3 can support the four support parts 5 of the MIM part 1 respectively.

[0037] The positioning groove 3 has four groove walls, which are fitted and fixed to the four peripheral walls of the MIM part 1.

[0038] One of the groove walls of the positioning groove 3 is provided with a receiving notch 7, which extends away from the center line of the positioning groove 3. The receiving notch 7 is used for the corner protrusion 29 of the MIM part 1 to be inserted.

[0039] The positioning groove 3 has at least one clearance notch 9 on its wall. In this embodiment, there are three clearance notches 9. The clearance notches 9 extend away from the center line of the positioning groove 3. The three clearance notches 9 are set one-to-one with the three corners of the MIM component 1.

The diameter of the through hole 11 is larger than the minimum width of the MIM part 1 and smaller than the maximum width of the MIM part 1, so that at least part of the projection of the cover plate 10 coincides with the projection of the MIM part 1 in the positioning groove 3, thereby pressing the MIM part onto the carrier plate 2. In this embodiment, each cover plate 10 has twelve through holes 11. The hole wall of the through hole 11 has an enlarged hole 12. The enlarged hole 12 can facilitate the up and down movement of the tool and also facilitate chip removal. The hole wall of the through hole 11 has a conformal notch 13 for the protrusion 30 of the MIM part 1 to be inserted. There are two conformal notches 13, including a strip notch communicating with the through hole 11 and an arc notch communicating with the strip notch.

In this embodiment, the cover plate 10 has two through notches 14, which are arranged along the width direction of the cover plate 10, and the two through notches 14 divide the cover plate 10 into three interconnected sections.

[0043] The cover plate 10 is fixed to the carrier plate 2 by the fastener 15. The fastener 15 includes a plurality of locking elements 16, and the locking elements 16 are set one-to-one with the plates. The through notch 14 is located between two adjacent locking elements 16. In this embodiment, the locking element 16 is a bolt. The bolt passes through each plate and connects to the carrier plate 2. In order to improve the connection stability of each plate, four through holes 11 on each plate are opened around the bolt.

[0044] The carrier plate 2 has at least two positioning pins 17. In this embodiment, there are two positioning pins 17. The cover plate 10 has pin holes 18. The positioning pins 17 are inserted into the pin holes 18. The pin holes 18 are located at both ends near the length direction of the cover plate 10.

[0045] The carrier plate 2 is provided with a support platform 19 on the side away from the cover plate 10. The support platform 19 has a pin 20, and the carrier plate 2 has a mounting hole 21 for inserting the pin 20. The support platform 19 is provided with a plurality of pads 22, each pad 22 is arranged along the height direction of the support platform 19, and the carrier plate 2 is arranged on the pads 22. The multiple pads 22 arranged on the support platform 19 can accommodate different carrier plates 2.

[0046] The support platform 19 has a support base 23 on the side away from the carrier plate 2. The support platform 19 has multiple connection holes 24. The support base 23 is provided with a support column 25. The support column 25 is connected to the connection hole 24 by bolts.

[0047] The support base 23 is also equipped with a cylinder 26. A gripper 27 is hinged to the piston rod of the cylinder 26, and a swing rod 28 is hinged to the gripper 27. The swing rod 28 and the cylinder body of the cylinder 26 are rotatably connected.

[0048] The above are all preferred embodiments of this utility model patent, and are not intended to limit the scope of protection of this utility model patent.
