Description

Technical Field

[0001] This utility model relates to the technical field of excavator bucket tooth installation and disassembly, and in particular to an auxiliary device for excavator bucket tooth installation and disassembly. Background Technology

[0002] Excavator bucket teeth are an important component of excavators, similar to human teeth. They are also wear parts and are connected to the tooth holder by a pin. Since the worn and failed part is the tip of the bucket tooth, it is only necessary to replace the bucket tooth. The bucket teeth and tooth holder of existing excavator buckets are connected by a pin, and the pin hole on the tooth holder and the bucket tooth is slightly smaller than the pin. Since the bucket teeth are consumables, they need to be installed and disassembled many times during excavation.

[0003] To ensure the stability of the bucket teeth after installation, the grooves inside the bucket teeth are usually matched with the specifications of the protruding parts of the tooth seat. During disassembly, a hammer is usually used with auxiliary tools to knock off the pin, and then the bucket teeth are hammered to disassemble them. During installation, the bucket teeth are fitted onto the outside of the tooth seat, and then the pin is hammered into the pin hole to complete the installation.

[0004] However, during installation, the outer side of the tooth holder and the bucket tooth installation position lacks auxiliary structures. When the pin is hammered, the force generated during hammering may cause the bucket tooth to shift position outside the tooth holder, which in turn causes the pin hole on the side wall of the tooth holder and the bucket tooth to shift position. As a result, the pin cannot be completely inserted into the pin hole, thus affecting the installation process of the bucket tooth.

[0005] To address this issue, we propose an auxiliary device for installing and removing excavator bucket teeth. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary device for installing and disassembling excavator bucket teeth.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An auxiliary device for installing and removing excavator bucket teeth includes a set of clamps, a tooth base, and a tooth retainer. The set of clamps is respectively sleeved on the outside of the tooth base and the tooth retainer. Each clamp includes a set of C-shaped fixing frames. A fixing pin is provided between the set of fixing frames to connect and fix the two. A set of guide rods is connected to one side wall of the clamp, and a guide frame is connected to the other side wall of the clamp. The other end of the set of guide rods extends through the guide frame to the other side. An adjusting tooth is provided between the guide rod and the guide frame.

[0009] Preferably, the fixed frame includes a set of support rods and a pad. The set of support rods are respectively disposed on both sides of the tooth seat, and the pad is rotatably disposed between the support rods on both sides. The pad is made of rubber material, and a friction layer is covered on the lower end surface of the pad.

[0010] Preferably, a limiting frame is connected to the lower side wall of the fixed frame, the upper side of the fixed frame extends into the limiting frame, and the adjacent side wall surfaces of the two are covered with a sealing ring structure. A fixing screw hole is provided on the side wall of the limiting frame, and the fixing pin is screwed into the fixing screw hole.

[0011] Preferably, one end of the guide rod located on the other side of the guide frame is connected to a limiting plate.

[0012] Preferably, the adjusting tooth is rotatably mounted on the inner wall of the guide frame, and the guide rod has a tooth groove on the side wall corresponding to the position of the adjusting tooth. The adjusting tooth meshes with the tooth groove, and an adjusting knob is connected to the outer end of the adjusting tooth shaft.

[0013] Preferably, pin holes are provided on both the tooth base and the sidewall of the tooth holder, and a coating plate is provided inside the pin hole. The surface of the coating plate is covered with a brush layer and the sidewall is in contact with the inner wall of the pin hole.

[0014] Preferably, a connecting rod is rotatably connected to the side wall of the mounting frame, and the coating plate is rotatably connected to the lower end face of the connecting rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In use, this invention utilizes the coordinated action of the adjusting teeth and tooth grooves to move the guide rod along the guide frame, thereby bringing the clamps on both sides closer together. This allows the clamp teeth to be fitted onto the tooth base. After the clamp teeth are installed, the clamps, guide rod, and guide frame work together to form a fixed structure on the outside of the clamp teeth and tooth base, ensuring stability during the hammering of the pin shaft. This prevents the pin holes on the tooth base and the sidewalls of the bucket teeth from shifting. Furthermore, the included applicator allows lubricant to be applied to the inside of the pin holes, facilitating the smooth insertion of the pin shaft. The combination of the fixing pin and fixing screw hole allows adjustment of the relative positions of the upper and lower fixing frames, thereby changing the size of the clamps and making them suitable for clamp teeth of different sizes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-3 An auxiliary device for installing and removing excavator bucket teeth, comprising the following structure:

[0028] A set of clamps 1, a tooth base, and a tooth are provided. The tooth has a groove on its sidewall for fitting onto the tooth base. The clamps 1 are respectively fitted onto the outer sides of the tooth base and the tooth. Each clamp 1 includes a C-shaped fixing frame 2. The fixing frame 2 contains a set of support rods 201 and a pad 202. The support rods 201 are respectively positioned on both sides of the tooth base. The pad 202 is rotatably positioned between the support rods 201 on both sides. The pad 202 can be rotated to adjust its angle, thus ensuring it always fits against the sidewalls of the tooth and tooth base. The pad 202 is made of hard rubber to ensure structural stability while preventing damage to the tooth and tooth base structure. Furthermore, the lower surface of the pad 202 is covered with a friction layer to increase friction and ensure the fixing frame 2 fits snugly against the tooth. To ensure the stability of the outer side of the tooth seat, a fixing pin 3 is provided between a set of fixing frames 2 to connect and fix the two. A limit frame 301 is connected to the side wall of the lower fixing frame 2, and the upper fixing frame 2 extends into the limit frame 301. The adjacent side wall surfaces of the two are covered with a sealing ring structure, so that there is a certain friction between the two to prevent slippage. A fixing screw hole 302 is provided on the side wall of the limit frame 301, and the fixing pin 3 is screwed into the fixing screw hole 302. By adjusting the distance between the upper and lower fixing frames 2, the size of the clamp 1 can be changed, so that the clamp 1 can be used for different sizes of clamp teeth. The fixing pin 3 can be used to fix the position of the fixed frame 2 after adjustment, so that the size of the clamp 1 remains stable.

[0029] Based on the above structure, the present invention has the following embodiments:

[0030] In use, move the clamping teeth to the outside of the tooth base, and then fit a set of clamps 1 onto the outside of the tooth base and the clamping teeth respectively. Then, according to the size of the tooth base and the clamping teeth, push the support rods 201 in the upper and lower fixing frames 2 towards the middle at the same time, and rotate the angle of the adjustment pad 202 so that the pad 202 fits against the side wall of the tooth base and the clamping teeth. At this time, the clamps 1 formed by the upper and lower fixing frames 2 fit and fix with the tooth base and the clamping teeth. Then, screw the fixing pin 3 to cooperate with the fixing screw hole 302 to fix the position of the adjusted support rods 201 on the upper and lower sides, thereby fixing the position of the upper and lower fixing frames 2, thus ensuring the structural stability of the clamps 1 and fixing them to the outside of the tooth base and the clamping teeth 1.

[0031] Reference Figure 4An auxiliary device for installing and removing bucket teeth of an excavator, further comprising the following structure: a set of guide rods 4 are connected to the side wall of one clamp 1, and a guide frame 5 is connected to the side wall of the other clamp 1. The other end of the set of guide rods 4 extends through the guide frame 5 to the other side. A limit plate 501 is connected to the end of the guide rod 4 on the other side of the guide frame 5 to prevent the guide rod 4 from leaving the working range of the guide frame 5. An adjusting tooth 6 is provided between the guide rod 4 and the guide frame 5. The adjusting tooth 6 is rotatably mounted on the inner wall of the guide frame 5. A tooth groove 601 is provided on the side wall of the guide rod 4 corresponding to the position of the adjusting tooth 6. The adjusting tooth 6 meshes with the tooth groove 601. The guide rod 4 moves along the guide frame 5, which in turn moves the clamps 1 on both sides closer together, causing the clamping teeth to be fitted onto the tooth seat. The outer end of the adjusting tooth 6 is connected to the adjusting knob 602. The adjusting knob 602 has a damping structure at its rotation point. The damping effect prevents the adjusting knob 602 and the adjusting tooth 6 from reversing, thus ensuring that the clamps 1 on both sides are fixed after adjustment. After the clamping teeth are fitted and installed, a fixed structure is still formed on the outside of the clamping teeth and the tooth seat, thus ensuring the stability of both during the hammering of the pin shaft and preventing the pin hole position on the tooth seat and the side wall of the bucket tooth from shifting, so that the pin shaft can be hammered in smoothly.

[0032] Based on the above structure, the present invention has the following embodiments:

[0033] Turning the adjustment knob 602 causes the adjustment gear 6 to rotate, and the adjustment gear meshes with the tooth groove 601, causing the guide rod 4 to move along the direction of the guide frame 5. This causes the clamp 1 on the outside of the clamp tooth to move closer to the clamp 2 on the outside of the tooth seat, thus moving the clamp tooth and gradually fitting it onto the outside of the tooth seat. When the clamp tooth is completely fitted onto the outside of the tooth seat, the pin holes on the side walls of both are aligned. At this time, the damping structure of the adjustment knob 602 is used to stabilize the tooth seat and the outside of the clamp tooth on both sides, forming a fixed structure to ensure the stability of the connection. Then, the pin is inserted into the pin hole, and a hammer is used to hammer the pin so that it is fully inserted into the pin hole to fix the tooth seat and the clamp tooth. After the clamp tooth is installed, loosening the fixing pin 3 can release the position fixation of the upper and lower support rods 201, so that the upper and lower fixing frames 2 are moved away from the size of the enlarged clamp 1, and then the device can be removed.

[0035] Based on the above structure, the present invention has the following embodiments:

[0036] Before inserting the pin, first squeeze the lubricating material onto the coating plate 7, then rotate the connecting rod 701 to make the coating plate 7 rotate into the pin hole. Rotate the coating plate 7 to apply the lubricating material into the pin hole. After the application is complete, rotate the coating plate 7 out to start the pin installation.
