Technical Field

[0001] This utility model relates to the field of long-handled grinding head technology, specifically a detachable structure for a long-handled grinding head. Background Technology

[0002] A long-handled grinding head is a grinding tool typically used in conjunction with equipment such as electric grinders, overhead grinders, or hand drills for grinding, lapping, and polishing various materials. Long-handled grinding heads also have wide applications in industrial production, such as long-handled polishing machines, which are highly efficient robotic polishing devices that can automatically complete complex polishing tasks, improving production efficiency and product quality.

[0003] However, in current technology, long-handled grinding heads are manufactured as a single piece, and the grinding head often needs to be replaced due to wear during use. Since the grinding head is a single piece, the entire grinding head and handle need to be replaced, which wastes material in the handle and increases the cost of grinding head replacement. Utility Model Content

[0004] The purpose of this invention is to provide a separable structure for a long-handled grinding head to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A separable structure for a long rod grinding head includes a rod body and a grinding head. A connecting assembly for connecting the rod body and the grinding head is provided between them. The connecting assembly includes a plurality of protrusions disposed at one end of the rod body. An insertion rod is disposed at one end of the rod body, and a positioning groove is disposed at the end of the insertion rod away from the rod body.

[0007] The grinding head has multiple mating grooves near one end of the rod body. Each of the multiple mating grooves has a through hole, and a tapered screw is installed inside the through hole. The grinding head has a cavity inside, and a locking block is installed inside the cavity.

[0008] As a preferred embodiment of this utility model, a plurality of the protruding plates are arranged in a ring on one end of the rod near the grinding head, and a plurality of the mating grooves are arranged on the outside of the grinding head and correspond to the protruding plates at one end of the rod.

[0009] As a preferred embodiment of this utility model, one end of the plurality of protruding plates can be embedded in the docking groove outside the grinding head and slide to dock with the inner wall of the docking groove. After docking, the bolt holes in the protruding plates correspond to the through holes inside the docking groove. The through holes are tapered and communicate with the cavity.

[0010] As a preferred embodiment of this utility model, one end of the insertion rod is connected to the rod body by welding, and the other end can be embedded in the cavity at one end of the grinding head, and the positioning groove at one end of the insertion rod corresponds to the locking block structure on the inner wall of the cavity.

[0011] As a preferred embodiment of this utility model, when the protruding plate on the outside of the rod body is inserted into the mating groove on the outside of the grinding head, the insertion rod at one end of the rod body is linked and embedded in the cavity, and the positioning groove at one end of the insertion rod is mated and embedded with the locking block.

[0012] As a preferred embodiment of this utility model, the outer wall of the insertion rod is provided with a plurality of bolt holes distributed in a ring, which correspond to the through holes in the mating groove after being embedded in the cavity. The tapered screw passes through the protrusion plate and the through hole in sequence, extends into the cavity, and is embedded in the bolt holes on the outer wall of the insertion rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In response to the problems raised in the background art, this application adopts a connecting component. By setting the long rod grinding head as a split structure, the grinding head and the rod are embedded and connected by the protrusion plate and the insert rod at the joint of the rod and the grinding head, and installed and fixed with screws. This allows the grinding head and the rod to be assembled and connected, which facilitates the quick replacement of the grinding head. Through the split assembly structure, the long rod grinding head can be replaced by only replacing the grinding head, while the rod is retained. This allows the rod to be used for replacing multiple grinding heads, saving replacement materials and reducing the replacement cost of the grinding head.

[0014] This invention transforms the long-handled grinding head into a split structure, which is then assembled and connected by inlay. When the grinding head is replaced, the handle is retained, allowing the handle to be used multiple times, thus saving replacement costs and material requirements. Attached Figure Description

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Example

[0022] Please see Figure 1-5 This utility model provides a technical solution: a separable structure for a long rod grinding head, including a rod body 1 and a grinding head 4. A connecting assembly for connecting the rod body 1 and the grinding head 4 is provided between them. The connecting assembly includes multiple protruding plates 2 disposed at one end of the rod body 1. An insert rod 3 is provided at one end of the rod body 1. A positioning groove 301 is provided at the end of the insert rod 3 away from the rod body 1. The protruding plates 2 can be inserted into the docking groove 5 outside the grinding head 4 when the rod body 1 and the grinding head 4 are docked. At the same time, the insert rod 3 at one end of the rod body 1 is simultaneously embedded into the cavity 6 of the grinding head 4, and the positioning groove 301 at one end of the insert rod 3 corresponds to the locking block 7 clamp in the cavity 6. The rod body 1 is assembled by inserting it into the grinding head 4. After insertion, the bolt holes on the outside of the protrusion plate 2 and the insertion rod 3 correspond to and communicate with the through hole 501 in the grinding head 4. Then, the protrusion plate 2 and the through hole 501 are finally embedded into the insertion rod 3 through the tapered screw 8, thereby fixing the rod body 1 and the grinding head 4. The deeper the tapered structure of the tapered screw 8 is inserted, the tighter the connection between the grinding head 4 and the rod body 1. By changing the long rod grinding head into a split structure and assembling it by insertion, when it is damaged and needs to be replaced, only the grinding head 4 needs to be disassembled and replaced, while the rod body 1 is retained so that it can be used multiple times, saving replacement material consumption and replacement costs.

[0023] The grinding head 4 has multiple mating grooves 5 near the end of the rod body 1. Each of the multiple mating grooves 5 has a through hole 501 inside. A tapered screw 8 is installed inside the through hole 501. The grinding head 4 has a cavity 6 inside. A locking block 7 is installed inside the cavity 6.

[0024] In this embodiment, all electrical components are controlled by a conventional controller.

[0025] For an example, please refer to... Figure 1-5Multiple protruding plates 2 are annularly distributed on one end of the rod 1 near the grinding head 4. Multiple mating grooves 5 are annularly distributed on the outside of the grinding head 4, corresponding to the protruding plates 2 at one end of the rod 1. One end of each protruding plate 2 can be embedded into the mating groove 5 on the outside of the grinding head 4 and slide to engage with the inner wall of the mating groove 5. After engagement, the bolt holes in the protruding plates 2 correspond to the through holes 501 inside the mating groove 5. The through holes 501 are tapered and communicate with the cavity 6. One end of the insertion rod 3 is connected to the rod 1 by welding, and the other end can be embedded into the cavity 6 at one end of the grinding head 4. The positioning groove 301 at one end of the insertion rod 3 corresponds to the locking block 7 structure on the inner wall of the cavity 6. When the protrusion 2 on the outside of the rod body 1 is inserted into the mating groove 5 on the outside of the grinding head 4, the insertion rod 3 at one end of the rod body 1 is linked and embedded into the cavity 6. The positioning groove 301 at one end of the insertion rod 3 is mated and embedded with the locking block 7. The outer wall of the insertion rod 3 has multiple bolt holes distributed in a ring, and after being embedded into the cavity 6, they correspond to the through hole 501 in the mating groove 5. The tapered screw 8 passes through the protrusion 2 and the through hole 501 in sequence and extends into the cavity 6 and is embedded with the bolt hole on the outer wall of the insertion rod 3. When using the new grinding head 4, simply remove it and keep the rod body 1. Then, connect the new grinding head 4 with the retained rod body 1, so that the protruding plate 2 and the insert rod 3 on the outside of the rod body 1 are inserted into the mating groove 5 and cavity 6 of the grinding head 4, so that the grinding head 4 and the rod body 1 are inserted and connected. After insertion, ensure that the bolt holes on the outside of the protruding plate 2 and the insert rod 3 are connected to the through hole 501 in the mating groove 5. Then, the tapered screw 8 passes through the protruding plate 2 and the through hole 501 and is inserted into the insert rod 3 to connect and fix the rod body 1 and the grinding head 4.

[0026] The working process of this utility model is as follows: When replacing the grinding head, simply remove the grinding head 4 while retaining the rod body 1. Then, align the new grinding head 4 with the retained rod body 1, ensuring that the external protrusion 2 and insert rod 3 of the rod body 1 are inserted into the mating groove 5 and cavity 6 of the grinding head 4, thus connecting the grinding head 4 to the rod body 1. After insertion, ensure that the bolt holes on the external protrusion 2 and insert rod 3 communicate with the through hole 501 in the mating groove 5. Then, insert the tapered screw 8 through the protrusion 2 and through hole 501 into the insert rod 3 to connect and fix the rod body 1 to the grinding head 4. This utility model transforms the long rod grinding head into a split structure, which is assembled and connected through inlay. The rod body is retained when the grinding head is replaced, allowing for multiple uses and saving replacement costs and material requirements.
