[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0038] Example: Please refer to Figures 1-8 A small excavator connecting rod processing and grinding device includes a locking block 1, and an adjustment component 2 is slidably installed at the end of the locking block 1. The angle of the connecting rod is adjusted by the adjustment component 2.
[0039] In this design, both ends of the locking block 1 are equipped with bolts or other fixing components for locking the adjusting component 2 and the locking component 3. The side of the support plate 28 has a movable groove, and the inner wall of the movable groove fits into the outer surface of the end of the locking block 1, thus facilitating the adjustment of the position of the adjusting component 2 on the support plate 28, making it suitable for different scenarios.
[0040] Furthermore, the locking component 3 is assembled on one side of the snap-fit block 1, and the end of the locking component 3 is slidably connected to the end of the adjusting component 2. The locking component 3 guides the processing end of the connecting rod. The locking component 3 includes a base plate 31 fixedly connected to the snap-fit block 1. The cross-section of the base plate 31 is concave. A power component 32 is fixedly installed on one side of the base plate 31, and a rotating shaft 33 is fixedly installed at the output end of the power component 32.
[0041] In this embodiment, the power component 32 is a device with power output, such as a motor, and is connected to an external control device. When the power component 32 is started, it synchronously drives the rotating shaft 33, which is fixedly installed at its output end, to rotate.
[0042] Meanwhile, a cover plate 311 is fixedly installed at the end of the base plate 31 to isolate it from the outside and prevent external particles from entering its interior.
[0043] Furthermore, a rotating cylinder 331 is fixedly installed on the outer surface of the rotating shaft 33, and a guide groove 332 is provided on the outer surface of the rotating cylinder 331.
[0044] Specifically, when the rotating shaft 33 is subjected to force and rotates, it synchronously drives the rotating cylinder 331, which is fixedly installed on its outer surface, to rotate, and in conjunction with the guide groove 332 opened on its outer surface, drives the drive rod 35 to move.
[0045] Furthermore, a protective block 34 is rotatably mounted on the end of the base plate 31 away from the power component 32, and protective grooves 341 are symmetrically opened on the outer surface of the protective block 34.
[0046] Specifically, the end of the protective block 34 is provided with bolts and other fixing components. The angle between the protective block 34 and the base plate 31 can be adjusted according to different needs to make it suitable for different scenarios. After the adjustment is completed, it is locked with bolts.
[0047] Meanwhile, the drive rod 35 is constrained by the protective groove 341 on the outer surface of the protective block 34, so that the whole remains stable when the drive rod 35 moves.
[0048] Furthermore, a drive rod 35 is slidably installed on the inner wall of the protective groove 341, and a docking block 351 is fixedly installed at the end of the drive rod 35. The outer surface of the end of the docking block 351 is slidably connected to the inner wall of the guide groove 332.
[0049] Specifically, when the rotating drum 331 rotates, it synchronously drives the guide groove 332 to rotate, and drives the drive rod 35, which is slidably installed on the inner wall of the guide groove 332, to move. Since the outer surface of the drive rod 35 is slidably connected to the inner wall of the protective groove 341, the drive rod 35 extends and retracts along the inner wall of the protective groove 341 after being subjected to force.
[0050] Furthermore, the end of the drive rod 35 extends through and to the outside of the protective block 34, while the end of the drive rod 35 is fixedly mounted with a power block 36.
[0051] Specifically, the end of the power block 36 is provided with a docking groove, and the inside of the docking groove is provided with bolts and other components that have a fixing function, and the fixing plate 38 is locked by the bolts.
[0052] Furthermore, the guide groove 332 is concave in its unfolded state, and a locking plate 37 is fixedly installed at the middle position of the end of the protective block 34, so that the drilling position can be adjusted by the locking plate 37.
[0053] Specifically, the position of the rotating hole is calibrated by locking plate 37, and the position of the rotating hole at both ends of the connecting rod is limited by power block 36 to ensure that the two rotating hole positions maintain relative position and dimensional accuracy.
[0054] Furthermore, a fixing plate 38 is fixedly installed on one side of the power block 36, and a fixing groove 381 is formed on one side of the fixing plate 38. A movable block 39 is fixedly installed at one end of the fixing plate 38, and a movable rod 391 is rotatably installed at the end of the movable block 39. A guide plate 392 is symmetrically rotatably installed on the outer surface of the movable rod 391. The outer surface of the end of the guide plate 392 is slidably connected to the inner wall of the fixing groove 381, and the outer surface of the guide plate 392 is in contact with the end of the connecting rod.
[0055] Specifically, the inner wall of the movable block 39 is equipped with a power output device such as a motor. The motor drives the movable rod 391 to rotate, thereby synchronously driving the guide plate 392, which is rotated and installed on its outer surface, to move. The movable rod 391 is a bidirectional threaded rod with opposite thread directions at both ends.
[0056] Since the outer surface of the guide plate 392 is slidably connected to the inner wall of the fixing groove 381, the guide plate 392 moves along the inner wall of the fixing groove 381 after being subjected to force, thereby locking the end of the connecting rod.
[0057] A locking ring is rotatably mounted on the end of the guide plate 392. The locking ring rotates in the opposite direction to the movement direction of the power block 36. Thus, when the power block 36 moves, the angle of the connecting rod can be adjusted without affecting the grinding state. This allows the grinding part of the connecting rod to be adjusted when the power block 36 moves in the locked state, making it suitable for the current scenario.
[0058] Furthermore, the adjusting assembly 2 includes a support plate 28 that is slidably connected to the snap-fit block 1. A groove 282 is formed at the end of the support plate 28, and a ball 27 is rotatably mounted on the inner wall of the groove 282. A rotating block 24 is fixedly mounted on the outer surface of the ball 27, and a support rod 23 is rotatably mounted on the end of the rotating block 24.
[0059] In this embodiment, the ball 27 is constrained by the groove 282 at the middle position of the end of the support plate 28, so that the support plate 28 can rotate around the ball 27 after being subjected to force, thereby adjusting the angle between the connecting rod and the grinding equipment, making it suitable for different scenarios.
[0060] At the same time, the rotating block 24 and the support rod 23 support the ball 27, so that the ball 27 is stably in the designated position.
[0061] Furthermore, a fixing block 21 is rotatably mounted on the end of the support rod 23, the end of the support rod 23 passes through and extends to the outside of the fixing block 21, and a driving member 211 is fixedly mounted on the end of the fixing block 21, the output end of the driving member 211 is fixedly connected to the end of the support rod 23.
[0062] Specifically, the drive component 211 is a device with power output, such as a motor, and is connected to an external control device. When the drive component 211 is started, it synchronously drives the support rod 23 set at its output end to rotate, and drives the rotating block 24 fixedly installed on the outer surface of the support rod 23 to rotate.
[0063] Furthermore, a positioning plate 22 is symmetrically fixedly installed at the end of the fixing block 21. The end of the positioning plate 22 is inclined, and a positioning groove 221 is provided at the end of the positioning plate 22.
[0064] Specifically, the positioning plate 22 is symmetrically arranged on the fixed block 21 and is slidably connected to the outer surface of the adjusting block 251 through the positioning groove 221, thereby adjusting the position of the adjusting plate 25 to suit the current scenario.
[0065] Furthermore, rotating rods 241 are rotatably mounted on both ends of rotating block 24, and connecting blocks 242 are rotatably mounted on the ends of rotating rods 241, and adjusting plates 25 are fixedly mounted on the ends of connecting blocks 242; the ends of adjusting plates 25 are inclined, and adjusting blocks 251 are fixedly mounted on the ends of adjusting plates 25, and the outer surface of adjusting blocks 251 is slidably connected to the inner wall of positioning groove 221.
[0066] Specifically, since the ends of the adjusting plate 25 and the positioning plate 22 are inclined, the adjusting plate 25 moves up and down as it slides along the end of the positioning plate 22. Simultaneously, the adjusting plate 25 is constrained by the connecting block 242 fixedly installed at the end of the adjusting plate 25 in conjunction with the rotating rod 241. The end of the rotating rod 241 is rotatably connected to the end of the rotating block 24, allowing the rotating rod 241 to rotate synchronously with the rotating block 24, providing power to the adjusting plate 25.
[0067] Furthermore, telescopic rods 26 are symmetrically fixedly installed at the ends of the adjusting plate 25, and an annular groove 281 is provided at the ends of the support plate 28. The inner wall of the annular groove 281 is slidably connected to the outer surface of the ends of the telescopic rods 26.
[0068] Specifically, the telescopic rod 26 has a rod that can be freely adjusted in height. The outer surface of the end of the telescopic rod 26 is fitted into the inner wall of the annular groove 281, so that when the telescopic rod 26 moves up and down with the adjusting plate 25, it drives the support plate 28 to rotate around the ball 27, thereby adjusting the angle of the connecting rod to make it suitable for different scenarios.
[0069] The control device can be a microcontroller as the control terminal. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., essentially a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantage is its small size, allowing it to be placed inside the instrument, but it has limited storage capacity, simple input / output interfaces, and low power consumption.
[0070] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
