In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0019] Example
[0020] Combination Figure 1-5 A tool with a tool head replacement function shown in the figure comprises a tool rod 1 and a tool head 2 arranged at the front end of the tool rod 1, and a fixing component 3 is provided at the connection between the tool rod 1 and the tool head 2. The tool rod 1 and the tool head 2 of the utility model adopt a split design, and the tool head 2 and the tool rod 1 can be separated and replaced. Not only can the processing be achieved by replacing the tool head 2 according to the processing type of the workpiece, the application scope of the tool rod 1 is increased. At the same time, the tool rod 1 does not need to be disassembled on the tool holder during the replacement process, which reduces the time spent on tool adjustment, improves production efficiency, and thus reduces enterprise costs.
[0021] like Figure 3 The tool rod 1 shown in the figure has a first assembly block 11 at the front end thereof, first threaded rods 111 are symmetrically provided on the left and right sides of the first assembly block 11, and a docking groove 112 is provided on the end surface of one side of the first assembly block 11 close to the tool head 2.
[0022] like Figure 4 The cutter head 2 shown in the figure has a second assembly block 21 at the end thereof, a docking plate 211 matched with the docking groove 112 is provided on the second assembly block 21, second threaded rods 212 which can cooperate with the first threaded rod 111 to form a complete threaded rod are symmetrically provided on the left and right sides of the second assembly block 21, and reinforcing plates 113 with a trapezoidal structure are symmetrically provided on the upper and lower end surfaces of the second assembly block 21 and the first assembly block 11.
[0023] like Figure 5 The fixing assembly 3 shown in the figure comprises a symmetrically arranged fixing part 31, and the fixing part 31 comprises an assembly plate 311 of a rectangular structure. The upper and lower sides of the assembly plate 311 are folded inward to form a symmetrical fixing plate 312. The fixing plate 312 has an inner end surface provided with a reinforcing groove 313 for plugging the reinforcing plate 113 on the tool rod 1 with the reinforcing plate 113 on the tool head 2 when the tool rod 1 is connected to the tool head 2. By arranging the reinforcing plate 113 and the reinforcing groove 313, the connection strength between the fixing assembly 3 and the tool rod 1 and the tool head 2 is further improved.
[0024] Furthermore, the assembly plate 311 is provided with a plurality of fastening grooves 315 for the reinforcing plate 113 to be inserted therethrough, and the fastening grooves 315 are connected one by one with the reinforcing grooves 313. By providing the fastening grooves 315, the connection strength between the fixing assembly 3 and the tool rod 1 and tool head 2 is further strengthened.
[0025] A further optimized solution is that a fixing hole 314 is formed on the assembly plate 311, through which a complete threaded rod composed of the first threaded rod 111 and the second threaded rod 212 can pass when the tool rod 1 is connected to the tool head 2, and then be fixed by a fixing nut 4. The double fixation of the connection between the tool head 2 and the tool rod 1 by the fixing piece 31 and the fixing nut 4 further enhances the firmness between the tool head 2 and the tool rod 1.
[0026] The working principle of the tool with the function of replacing the tool head in the utility model is as follows:
[0027] The tool bar 1 and the tool head 2 of the utility model adopt a split design, and the tool head 2 and the tool bar 1 can be separated and replaced. When it is necessary to install the tool head 2 that meets the processing type on the tool bar 1, the docking plate 211 on the end of the tool head 2 is aligned with the docking groove 112 on the front end of the tool bar 1 for plugging, so that the tool head 2 and the tool bar 1 are initially fixedly connected, and then the fixing hole 314 on the fixing member 31 is aligned with the complete threaded rod formed by the first threaded rod 111 and the second threaded rod 212 when the tool bar 1 and the tool head 2 are connected, and the reinforcing plates 113 on the tool bar 1 and the tool head 2 are plugged into the reinforcing groove 313 and the fastening groove 315 on the fixing member 31 in turn. The tool head 2 can be replaced and installed by screwing the fixing nut 4 onto the complete threaded rod formed by the first threaded rod 111 and the second threaded rod 212 when the tool head 2 is connected. The tool head 2 and the tool rod 1 after replacement and installation are firm and reliable. When the tool head 2 needs to be replaced and disassembled, the above operation can be reversed to complete the replacement and disassembly of the tool head 2. The structural design of the utility model is reasonable and simple. It can not only realize processing by replacing the tool head 2 according to the processing type of the workpiece, but also increase the application scope of the tool rod 1. At the same time, the tool rod 1 does not need to be disassembled on the tool holder during the replacement process, which reduces the time spent on tool adjustment, improves production efficiency, and thus reduces enterprise costs.
[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
