[0026] Schematic brake cam

[0027] refer to Figure 1 According to a preferred embodiment of the brake cam of the utility model, it should be noted that the structure of the brake cam is as follows Figure 1 As shown, it includes an insertion portion 10 and an extension portion 20, the insertion portion 10 is connected to the extension portion 20, and the cross-sectional dimension of the insertion portion 10 is larger than the cross-sectional dimension of the extension portion 20. In addition, two protrusions 21 are provided on both sides of the extension portion 20. It is worth mentioning that the insertion portion 10 and the extension portion 20 are integrally formed. In addition, it should be noted that the structure of the extension portion 20 is as shown in FIG. Figure 1As shown, the end of the extension portion 20 away from the insertion portion 10 is a profiled surface, and those skilled in the art should understand that the position of the profiled surface is located at the end, so milling and turning are usually used. Since the processing accuracy of the profiled surface is not high, our company uses milling. It should also be noted that the minimum cross-sectional dimension of the extension portion 20 is 30mm, and the cross-sectional dimension of the insertion portion 10 is 40mm, so that the distance between the extension portion 20 and the insertion portion 10 is only 5mm, so it will be difficult to use conventional clamping methods. Figure 5 The previous clamping method of our company includes a workbench 200 and two pressure plate assemblies, each of which includes a plate body 300, a supporting rod 400 and a rotating rod 500. The end of the insertion portion 10 away from the extension portion 20 is placed on the workbench 200, one end of the plate body 300 contacts the side of the insertion portion 10 close to the extension portion 20, and one end of the supporting rod 400 is threadedly connected to the side of the plate body 300 close to the workbench 200. Once the other end of the supporting rod 400 is abutted against the workbench 200, the plate body 300 is screwed to the side of the extension portion 20. On the plate body 300, one end of the rotating rod 500 passes through the plate body 300 and is threadedly connected to the workbench 200, and the other end is located at the top of the plate body 300, that is, the user can adjust the abutting rod 400 to limit the position of the plate body 300, and press the insertion part 10 by rotating the rotating rod 500. However, the above clamping method is difficult to press the side of the insertion part 10 close to the extension part 20 because the distance between the extension part 20 and the insertion part 10 is only 5mm. Therefore, our company designed a new clamp to ensure that the position of the brake cam can be limited, and at the same time, the structure of the brake cam has been partially improved to match the new clamp.

[0028] It is worth mentioning that Figure 3-4 The new clamp shown includes a placement plate 30, which is fixed by the above-mentioned multiple pressure plate assemblies. In addition, the center of the placement plate 30 also has a first installation groove 301, and the insertion part 10 cooperates with the first installation groove 301.

[0029] Furthermore, the side wall of the insertion portion 10 also has two limiting grooves 101, and the two limiting grooves 101 are respectively located on both sides of the insertion portion 10, and the side wall forming the first mounting groove 301 also has two second mounting grooves 302 arranged in phase, and the two second mounting grooves 302 correspond to the two limiting grooves 101 one by one. It is worth mentioning that a moving component is also arranged in each of the second mounting grooves 302, and each of the moving components includes a movable block 41 and an elastic member 42, and the wall surface forming the second mounting groove 302 and away from the extension portion 20 also has a guide block 3021, and the movable block 41 is movably arranged on the second mounting groove 302. The movable block 41 is provided with a first connection part on the top of the guide block 3021, and the movable block 41 is provided with a second connection part on the side close to the first connection part. The elastic member 42 is located on the upper side of the guide block 3021, and the two ends of the elastic member 42 are respectively connected to the first connection part and the second connection part. It should be understood by those skilled in the art that the movable block can be subjected to an external force and move a predetermined distance in the direction close to the limiting groove 101, so that the end of the movable block 41 away from the elastic member 42 is placed in the corresponding limiting groove 101, thereby limiting the position of the insertion part 10. The movable block 41 is provided on one side of the second connection part and also has a pressure surface, and the pressure surface is an inclined surface. The elastic member 42 can be a tension spring, that is, when the movable block 41 is no longer subjected to an external force, the elastic member 42 can pull the movable block 41 back to its original position.

[0030] Furthermore, the insertion portion 10 has two oppositely arranged notches 101 at one end close to the extension portion 20, and the two sides of the notches 101 facing away from each other are both connected to the outside. In addition, each bottom wall forming the notch 101 also has a first insertion hole 102, and the two first insertion holes 102 both penetrate the insertion portion 10. It is worth mentioning that the top of the placement plate 30 also has two oppositely arranged second insertion holes 303, and the two second insertion holes 303 correspond to the two first insertion holes 102 one by one, and the two second insertion holes 303 are also respectively corresponding to the two second mounting grooves 302. When the insertion portion 10 is placed in the first mounting groove 301, the first insertion hole 102 is directly opposite to the second insertion hole 303, thereby providing conditions for subsequent installation and pushing the guide block 3021 of the moving component, and the new fixture also includes two insertion rods 43, the two insertion rods 43 respectively pass through the two first insertion holes 102 and the two second insertion holes 303, and are respectively placed in the two second mounting grooves 302.

[0031] It should be noted that each of the first insertion holes 102 has a small hole and a large hole, the large hole is connected to the small hole, and the small hole is a threaded hole, so that the insertion rod 43 can be threadedly connected to the small hole, and then the threaded connection is used to control the position of the insertion rod 43, that is, the user can rotate the insertion rod 43 to squeeze the pressure surface of the movable block 41, so that the movable block 41 cooperates with the limiting groove 101, thereby limiting the position of the brake cam. In addition, the above-mentioned small hole can also be implemented as a conventional hole, and the second insertion hole 303 is implemented as a threaded hole. The end of the insertion rod 43 away from the movable block 41 is also located in the large hole.

[0032] In addition, the elastic member 42 can also be implemented as a conventional spring, and the two insertion rods 43 can be removed, that is, the elastic member 42 can stack the movable block 41 to a predetermined angle, that is, the end of the movable block 41 away from the elastic member 42 is placed outside, that is, when the insertion portion 10 is matched with the first mounting groove 301, the movable block 41 will be squeezed and retracted until the movable block 41 is matched with the corresponding limiting groove 101. In addition, if the above scheme is adopted, the bottom wall forming the first mounting groove 301 also has a matching block 3011, and the end of the insertion portion 10 away from the extension portion 20 also has a third mounting groove 103, the third mounting groove 103 is matched with the matching block 3011, so that it is worth limiting the position of the insertion portion 10, and the bottom wall forming the third mounting groove 103 also has a through hole 105. In addition, the bottom wall forming the third installation groove 103 also has a positioning hole 104, and the above-mentioned matching block 3011 can be provided with a positioning protrusion for matching with the positioning block, so as to limit the position of the brake cam.

[0033] In summary, the brake cam according to the embodiment of the present application is explained, which provides the brake cam with advantages such as easy cooperation with an external fixture, not easy to loosen, and easy processing.

[0034] It is worth mentioning that in the embodiment of the present application, the brake cam has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency.
