Description

Technical Field

[0001] The invention relates to a fittings processing technology, in particular to a connecting rod processing and polishing device for a small excavator. Background Art

[0002] Excavators primarily excavate soil, coal, silt, and pre-loosened soil and rock. In recent years, the development of construction machinery has seen relatively rapid growth in excavators, making them one of the most important types of machinery in engineering construction. To facilitate excavation, excavators are typically equipped with connecting rods, which facilitate bucket angle adjustment. These connecting rods are polished during production to prevent significant friction between the connecting rod and the excavator after installation.

[0003] A Chinese patent with publication number CN220145519U discloses a grinding device for processing connecting rods of small excavators. The grinding device for processing connecting rods of small excavators causes four adjusting rods to slide outward respectively by pulling four pull rings in sequence, and at the same time, four limit plates slide along the inner walls of four second sliding holes respectively. When the four clamping rods are separated from the four clamping holes respectively, the two slides can be slid out of the inner walls of the two first sliding grooves respectively, and then the grinding roller can be quickly disassembled to facilitate replacement according to small excavator connecting rods of different specifications. It has a wider range of applications and is convenient for staff to perform inspection and maintenance.

[0004] When existing equipment is in use, if the contact angle of the connecting rod is too large or too small, it will affect the quality of the workpiece surface, and then it will not be able to adapt to connecting rods of different specifications during grinding, resulting in differences from the set conditions after grinding. At the same time, the connecting rod needs to have two connecting holes ground at its end, and the two connecting holes have a certain positional relationship, but they cannot be accurately calibrated during grinding, resulting in deviations between the two connecting holes, affecting subsequent use. Therefore, a small excavator connecting rod processing and grinding device has been developed. Summary of the Invention

[0037] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] Example: See Figures 1-8 A small excavator connecting rod processing and grinding device includes a clamping block 1, and an adjusting component 2 is slidably installed on the end of the clamping block 1, and the angle of the connecting rod is adjusted by the adjusting component 2.

[0039] In this solution, bolts and other fixing components are provided at both ends of the clamping block 1 to clamp the adjustment assembly 2 and the locking assembly 3. A movable groove is provided on the side of the support plate 28, and the inner wall of the movable groove fits into the outer surface of the end of the clamping block 1, thereby facilitating the adjustment of the position of the adjustment assembly 2 on the support plate 28 to adapt it to different scenarios.

[0040] Furthermore, the locking assembly 3 is assembled on one side of the clamping block 1, and the end of the locking assembly 3 is slidably connected to the end of the adjusting assembly 2, and the processing end of the connecting rod is guided by the locking assembly 3; wherein, the locking assembly 3 includes a base plate 31 fixedly connected to the clamping block 1, and the cross-section of the base plate 31 is concave, and at the same time, a power part 32 is fixedly installed on one side of the base plate 31, and a rotating shaft 33 is fixedly installed on the output end of the power part 32.

[0041] In this embodiment, the power member 32 is a device with power output, such as a motor, and is connected to an external control device. When the power member 32 is started, it synchronously drives the rotating shaft 33 fixedly installed at its output end to rotate.

[0042] At the same time, a cover plate 311 is fixedly installed at the end of the bottom plate 31, which is isolated from the outside by the cover plate 311 to prevent external particles from entering the inside.

[0043] Furthermore, a rotating drum 331 is fixedly mounted on the outer surface of the rotating shaft 33 , and a guide groove 332 is formed on the outer surface of the rotating drum 331 .

[0044] Specifically, when the rotating shaft 33 is rotated by force, it synchronously drives the rotating drum 331 fixedly mounted on its outer surface to rotate, and cooperates with the guide groove 332 provided on its outer surface to drive the driving rod 35 to move.

[0045] Furthermore, a protection block 34 is rotatably mounted on the end of the bottom plate 31 away from the power member 32 , and protection grooves 341 are symmetrically formed on the outer surface of the protection block 34 .

[0046] Specifically, the end of the protective block 34 is provided with a fixing component such as a bolt. The angle between the protective block 34 and the base plate 31 is adjusted according to different needs to make it suitable for different scenarios, and it is locked by the bolt after the adjustment is completed.

[0047] At the same time, the driving rod 35 is limited by the protection groove 341 provided on the outer surface of the protection block 34, so that the driving rod 35 remains stable as a whole when the driving rod 35 moves.

[0048] Furthermore, a driving rod 35 is slidably mounted on the inner wall of the protection groove 341 , a docking block 351 is fixedly mounted on the end of the driving rod 35 , and an 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, the guide groove 332 is synchronously driven to rotate, and the driving rod 35 slidably installed on the inner wall of the guide groove 332 is driven to move. Since the outer surface of the driving rod 35 is slidingly connected to the inner wall of the protective groove 341, the driving rod 35 can telescopically move along the inner wall of the protective groove 341 after being subjected to force.

[0050] Furthermore, the end of the driving rod 35 passes through and extends to the outside of the protection block 34 , and the end of the driving rod 35 is fixedly mounted with a power block 36 .

[0051] Specifically, a docking groove is provided at the end of the power block 36 , and a fixing component such as a bolt is provided inside the docking groove, and the fixing plate 38 is locked by the bolt.

[0052] Furthermore, the guide groove 332 is concave in the expanded state, and a locking plate 37 is fixedly installed at the middle position of the end of the protective block 34, and the drilling position is adjusted by the locking plate 37.

[0053] Specifically, the position of the rotating hole is calibrated by the locking plate 37, and the positions of the rotating holes at both ends of the connecting rod are limited in cooperation with the power block 36, so as to ensure that the relative position and dimensional accuracy of the two rotating holes are maintained.

[0054] Furthermore, a fixed plate 38 is fixedly mounted on one side of the power block 36, and a fixing slot 381 is defined on one side of the fixed plate 38. A movable block 39 is fixedly mounted on one end of the fixed plate 38, and a movable rod 391 is rotatably mounted on the end of the movable block 39. A guide plate 392 is symmetrically rotatably mounted 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 slot 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 provided with a device with power output such as a motor, which drives the movable rod 391 to rotate, thereby synchronously driving the guide plate 392 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 end 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 installed at the end of the guide plate 392, and the rotation direction of the locking ring is consistent with the moving direction of the power block 36. Therefore, when the power block 36 moves, the angle of the connecting rod can be adjusted without affecting the grinding state. When the power block 36 moves in the locked state, the grinding position of the connecting rod can be adjusted to make it suitable for the current scene.

[0058] Furthermore, the adjustment assembly 2 includes a support plate 28 that is slidably connected to the clamping block 1. The end of the support plate 28 is provided with a groove 282, and the inner wall of the groove 282 is rotatably mounted with a ball 27. The outer surface of the ball 27 is fixedly mounted with a rotating block 24, and the end of the rotating block 24 is rotatably mounted with a support rod 23.

[0059] In this embodiment, the sphere 27 is limited by the groove 282 in the middle position of the end of the support plate 28, so that after the support plate 28 is subjected to force, it can rotate around the sphere 27, thereby adjusting the angle between the connecting rod and the grinding equipment, making it suitable for different scenarios.

[0060] At the same time, the sphere 27 is supported by the rotating block 24 and the supporting rod 23 so that the sphere 27 is stably located in a designated position.

[0061] Furthermore, a fixed block 21 is rotatably installed at the end of the support rod 23, and the end of the support rod 23 passes through and extends to the outside of the fixed block 21. At the same time, a driving member 211 is fixedly installed at the end of the fixed block 21, and the output end of the driving member 211 is fixedly connected to the end of the support rod 23.

[0062] Specifically, the driving member 211 is a device with power output such as a motor, and is connected to an external control device. When the driving member 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 mounted on the end of the fixing block 21 . The end of the positioning plate 22 is inclined, and a positioning groove 221 is formed on the end of the positioning plate 22 .

[0064] Specifically, the positioning plate 22 is symmetrically arranged on the fixing block 21 and is slidably connected to the outer surface of the adjustment block 251 through the positioning slot 221, thereby adjusting the position of the adjustment plate 25 to make it suitable for the current scene.

[0065] Furthermore, rotating rods 241 are rotatably installed at both ends of the rotating block 24, connecting blocks 242 are rotatably installed at the ends of the rotating rods 241, and adjusting plates 25 are fixedly installed at the ends of the connecting blocks 242; the ends of the adjusting plates 25 are inclined, and adjusting blocks 251 are fixedly installed at the ends of the adjusting plates 25, and the outer surface of the adjusting block 251 is slidably connected to the inner wall of the positioning groove 221.

[0066] Specifically, the adjustment plate 25 is inclined relative to the end of the positioning plate 22, and when the adjustment plate 25 slides along the end of the positioning plate 22, the adjustment plate 25 moves up and down. At the same time, a connecting block 242 fixedly mounted on the end of the adjustment plate 25 cooperates with a rotating rod 241 to restrain the adjustment plate 25. The end of the rotating rod 241 is rotatably connected to the end of the rotating block 24, so that the rotating rod 241 rotates synchronously with the rotating block 24 to provide power for the adjustment plate 25.

[0067] Furthermore, a telescopic rod 26 is symmetrically fixedly mounted on the end of the adjustment plate 25 , and an annular groove 281 is formed on the end of the supporting plate 28 . The inner wall of the annular groove 281 is slidably connected to the outer surface of the end of the telescopic rod 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 embedded in the inner wall of the annular groove 281, so that when the telescopic rod 26 moves up and down following the adjustment plate 25, the support plate 28 is driven to rotate around the sphere 27, thereby adjusting the angle of the connecting rod to make it suitable for different scenarios.

[0069] The control device can use a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (MCU), consisting of an arithmetic unit, a controller, memory, and input / output devices, equivalent to a miniature computer. Compared to the general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its greatest advantages are its small size, allowing it to be placed inside the instrument, low memory capacity, simple input / output interfaces, and low functional consumption.

[0070] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
