[0002] During gearbox assembly, the parts need to be cleaned to remove impurities such as metal shavings and oil stains. After cleaning, the parts need to be inspected to ensure that their quality meets the requirements.
[0003] During gearbox assembly, metal shavings removed from the gearbox accumulate on the base plate guide rails, potentially causing the fixture to slide unevenly. Existing technology involves operators stopping assembly and cleaning the guide rails with a cloth or similar tools. However, this method interferes with the clamping and securing of the gearbox during assembly. Therefore, this paper proposes an auxiliary tooling fixture for gearbox assembly, providing an alternative technical solution to this problem. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0035] like Figure 1 As shown, this type of auxiliary tooling fixture for gearbox assembly includes a base plate 1, a fixed clamping plate 3, two sliding members 4, a follower assembly 5, a transmission member 6, a chip removal mechanism 7, and a receiving mechanism 8. The fixed clamping plate 3 is fixed to one side of the top of the base plate 1 without moving. The follower assembly 5 is located on the other side of the top of the base plate 1 opposite to the fixed clamping plate 3 through the two sliding members 4, so that a clamping space is formed on the base plate 1 between the fixed clamping plate 3 and the follower assembly 5. The clamping space is used to place the gearbox body to be assembled and processed. The follower assembly 5 can move closer to the fixed clamping plate 3 through the two sliding members 4 to further reduce the clamping space and fix the gearbox in the clamping space.
[0036] The transmission component 6 is used to drive the follower component 5 to move closer to the fixed clamping plate 3 and limit the changed position of the follower component 5 so that the gearbox body is continuously fixed in the clamping space. Conversely, the transmission component 6 is also used to reduce the fixing force between the follower component 5 and the gearbox so that the gearbox can be disengaged from the clamping space.
[0037] The chip removal mechanism 7 is located on the sliding member 4 and is used to remove the iron filings that fall on the sliding member 4 to keep the sliding member 4 clean and allow the follower component 5 to move smoothly on the sliding member 4. Specifically, the chip removal mechanism 7 includes a push-pull part that can move linearly on the base plate 1 and two adsorption parts connected to one end of the push-pull part. The adsorption parts move along the length direction of the sliding member 4 by the push-pull part to pass almost completely over the sliding member 4 and adsorb almost all the iron filings on the sliding member 4 by magnetic attraction to remove them.
[0038] The receiving mechanism 8 is located on the base plate 1 and is used to collect the debris removed by the chip removal mechanism 7 into the receiving mechanism 8 so as to process the collected iron filings in a targeted manner. Specifically, the push-pull part not only drives the adsorption part to move past the sliding part 4, but also drives the adsorption part to the receiving mechanism 8. When the adsorption part comes to the receiving mechanism 8, the iron filings adsorbed on the adsorption part will be removed from the receiving mechanism 8 and fall into its interior.
[0039] like Figure 2 As shown, and for reference Figure 1 The sliding member 4 consists of a guide rail 41 fixed on the base plate 1 and a slider 42 (including but not limited to) slidably disposed on the guide rail 41; the follower assembly 5 includes a rod 51 disposed between at least two sliders 42 and a plate 53 that can be telescopically moved on the rod 51 by at least two elastic members 52; the transmission member 6 consists of an extrusion block 61 eccentrically rotatably connected to the base plate 1 and a handle 62 fixed on the extrusion block 61 to drive the extrusion block 61 to rotate.
[0040] The handle 62 drives the pressing block 61 to rotate. Due to the eccentric setting of the pressing block 61, the rotation of the pressing block 61 will cause it to rotate and feed a certain distance towards the fixed clamping plate 3 on one side of the rod 51. This will push the rod 51 to slide on the guide rail 41 through the slider 42, allowing the plate 53 indirectly connected to the rod 51 through the elastic element 52 to move into the clamping space formed between the rod 51 and the fixed clamping plate 3, so as to reduce the width or length of the clamping space and fix the gearbox that is in contact with the fixed clamping plate 3 and the rod 51 in the clamping space respectively.
[0041] Furthermore, such as Figure 3 As shown, and for reference Figure 1 and Figure 2 The plate 53 and the fixed clamping plate 3 are provided with several equally spaced rubber strips on the side that contacts the gearbox. The rubber strips are used to increase the friction between the plate 53 and the gearbox and effectively prevent the appearance of fixing marks on the surface of the gearbox. On this basis, the elastic element 52 is used to reduce the intensity of the plate 53 directly rigidly contacting the gearbox, making it even less likely to leave fixing marks on the gearbox.
[0042] The elastic element 52 is specifically composed of a guide rod 521 fixed to the plate 53 and passing through the rod 51, and a spring 522 sleeved outside the guide rod 521 and located between the rod 51 and the plate 53. When the extrusion block 61 initially rotates and drives the plate 53, the plate 53 will follow and move to contact the gearbox under the connection and cooperation of the spring 522 and the guide rod 521. When the extrusion block 61 further drives the plate 53, the plate 53 cannot move further due to the obstruction of the gearbox. At this time, the continuous feeding motion of the extrusion block 61 will be forceful on the spring 522, causing the spring 522 to be compressed for buffering.
[0043] Furthermore, such as Figure 4 As shown, and for reference Figure 1 and Figure 2 The extrusion block 61 is provided with a groove 611, and a limiting rod 612 fixed to the base plate 1 is provided in the groove 611. The limiting rod 612 is used to limit the rotation angle of the extrusion block 61. The side of the extrusion block 61 is provided with a cut surface 613, which is used to fit the rod body 51 to limit the rotation of the extrusion block 61.
[0044] In the initial state, the limiting rod 612 is located at one end of the slide groove 611, and the cut surface 613 is located on the side that intersects the rod body 51 at a 90-degree angle. The handle 62 can drive the extrusion block 61 to rotate at a certain angle, which is the angle at which the limiting rod 612 moves from one end of the slide groove 611 to the other end. At the same time, the cut surface 613 is rotated to a state of full contact with the rod body 51, and in this contact state, the original line contact between the extrusion block 61 and the rod body 51 is changed to a surface contact of a certain area, so that the rod body 51 and the cut surface 613 are in contact. The 13 forms a self-locking state after rotating a certain angle. In this self-locking state, the pressing block 61 is not easily rotated by external force, and the cooperation between the slide groove 611 and the limit rod 612 also restricts the rotation to either clockwise or counterclockwise, so as to ensure that the rod 51 does not move. However, after applying a certain force to the handle 62, the pressing block 61 can be driven to rotate quickly in the opposite direction to the initial angle when the spring 522 is reset. At this time, the plate 53 cancels the contact with the gearbox, and the gearbox can be disengaged from the clamping space.
[0045] like Figure 5 and Figure 6 As shown, and for reference Figure 1 The push-pull part of the chip removal mechanism 7 includes two carriers 71 located on the base plate 1, a handle 72 fixed between the two carriers 71, and a slide rod 73 fixed to the two carriers 71 respectively. The slide rod 73 is slidably connected to the base plate 1 through a blind hole opened in the base plate 1. A first magnet 75 is fixed to one side of the base 74, a converter seat 76 is rotatably connected to the top of the base 74, and a second magnet 77 is fixed to one side of the converter seat 76. A torsion spring 78 is connected between the base 74 and the converter seat 76. The second magnet 77 is rotatably limited on the base 74 through the converter seat 76 and the torsion spring 78.
[0046] The handle 72 drives the slide rod 73 to slide and extend within the blind hole in the base plate 1. The carrier 71 moves on the top surface of the base plate 1, and as the carrier 71 moves, the first magnet 75 and the second magnet 77 on the base 74 attract iron filings on the guide rail 41. To improve the iron filings attraction effect, the first magnet 75 and the second magnet 77 can repeatedly move forward and backward under the drive of the carrier 71. However, because the guide rail 41 is equipped with a slider 42, the obstruction of the slider 42 will limit the first magnet 75 and the second magnet 77 to only be able to remove iron filings from one side of the slider 42 to one end of the guide rail 41. However, because the second magnet 77 is connected to the adapter 76 and the torsion spring 7 The rotation limit is located on the base 74. When the second magnet 77 moves to attract and contact the slider 42, a slight lifting force is applied. The second magnet 77 will rotate on the base 74 through the adapter 76 and twist the torsion spring 78. At this time, the second magnet 77 can pass through the slider 42 and come to the other side of the slider 42. The torsion spring 78 resets the second magnet 77 and removes iron filings from the length from one side of the slider 42 to the other end of the guide rail 41. Thus, the iron filings on the guide rail 41 can be removed without the slider 42 disengaging from the guide rail 41 and without the fixed clamping plate 3 and the follower component 5 performing clamping and fixing, so as to maintain the cleanliness of the guide rail 41 and allow the slider 42 to slide smoothly on the guide rail 41.
[0047] like Figure 7 As shown, and for reference Figure 6 and Figure 5 An adsorption region 2 is formed between the first magnet 75 and the second magnet 77 of the two adsorption parts. The adsorption region 2 is larger than the cross-sectional path (i.e. the outer circumference of the end face) of the guide rail 41 in the vertical direction. The adsorption region 2 is preferably 1 to 3 cm away from the surface of the guide rail 41, so that the iron filings on the guide rail 41 are adsorbed on the side of the first magnet 75 and the second magnet 77 opposite to the guide rail 41.
[0048] The receiving mechanism 8 consists of a collection box 81 fixed on the base plate 1 and a scraper seat 82 fixed on the collection box 81. The scraper seat 82 is adapted to the adsorption area 2. After the first magnet 75 and the second magnet 77 adsorb too much iron filings, their magnetism will decrease, so they cannot continue to adsorb iron filings on the guide rail 41. When the first magnet 75 and the second magnet 77 adsorb too much iron filings, the lifting stroke can be increased so that the entire adsorption part moves to the scraper seat 82. At this time, the adsorption surfaces of the first magnet 75 and the second magnet 77 are in contact with the scraper seat 82. As the first magnet 75 and the second magnet 77 move further, the iron filings are blocked by the scraper seat 82 and fall off the first magnet 75 and the second magnet 77 and enter the collection box 81.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described.
