DETAILED DESCRIPTION

[0021] The technical scheme in the utility model will be further described below in combination with the drawings and embodiments.

[0022] As shown in Figure 1 and Figure 2 shown, the utility model embodiment proposes an assembly structure of a taper shank gear shaping cutter, used for connecting a tool handle 1 and a tool head 2, comprising:

[0023] A mounting portion 6 is arranged at the end of the tool handle 1, and the tool head 2 is sleeved on the mounting portion 6.

[0024] The fixing unit comprises a plurality of fixing blocks 3 and an adjusting member, the mounting portion 6 is provided with a plurality of mounting grooves 601 penetrating the side surface thereof, the plurality of fixing blocks 3 are respectively arranged in the plurality of mounting grooves 601 in a sliding mode, and the adjusting member is arranged in the mounting portion 6 in a sliding mode and abuts against the plurality of fixing blocks 3; when the adjusting member slides along the axis of the mounting portion 6, the plurality of fixing blocks 3 are synchronously expanded to abut against the inner side of the tool head 2.

[0025] In the embodiment of the utility model, the tool head 2 and the tool handle 1 are processed separately in the production of the taper shaper cutter, the tool head 2 is provided with through holes penetrating both ends thereof, the mounting portion 6 is arranged at the end of the tool handle 1 and fixedly connected with the tool handle 1, the tool head 2 can be directly assembled to the mounting portion 6 during the assembly of the taper shaper cutter, the quick assembly is realized, and when the tool head 2 is damaged during the subsequent work or transportation, the tool head 2 can be directly separated from the tool handle 1 and replaced, the tool handle 1 does not need to be discarded, material waste is reduced, and the production or maintenance cost is reduced.

[0026] Secondly, the taper shaper cutter generally performs frequent reciprocating motion during work, in order to ensure the stability of the tool head 2 during the work of the taper shaper cutter, the adjusting member is adjusted along the axial direction of the mounting portion 6 under the cooperation of the fixing unit, the fixing blocks 3 are synchronously extruded by the adjusting member and expanded, the side surface of the fixing block 3 gradually protrudes from the mouth of the mounting groove 601, until the fixing blocks 3 abut against the inner wall of the tool head 2, the extrusion and fixation of the tool head 2 are realized, the stability of the installation of the tool head 2 is ensured, the safety of the tool head 2 during work is ensured, when the tool head 2 is disassembled subsequently, the adjusting member is moved reversely in the position of the mounting portion 6, the adjusting member is separated from the fixing blocks 3, the limitation of the fixing blocks 3 is released, the limitation of the tool head 2 is quickly released, and the tool head 2 can be taken out.

[0027] Based on the above scheme, as shown in Figure 2 The adjusting member comprises an adjusting screw 4 arranged in rotation in the mounting portion 6 and a driving block 5 arranged in sliding between the mounting grooves 601, the driving block 5 is provided with a threaded sleeve 501, the driving block 5 is in transmission connection with the adjusting screw 4 through the threaded sleeve 501, the fixing blocks 3 and the driving block 5 both have guide inclined surfaces, and the two guide inclined surfaces are in sliding abutment.

[0028] Specifically, when each fixing block 3 is adjusted by the action of the adjusting member, the fixing block 3 is provided with a guide slope, which is inclined upward, so that the top of the fixing block 3 is small and the bottom is large. The driving block 5 also has a guide slope, which is inclined downward, so that the top of the driving block 5 is large and the bottom is small. Thus, the guide slope of the fixing block 3 can be fitted with the guide slope of the fixing block 3. Therefore, by rotating the adjusting screw 4, the adjusting screw 4 is automatically installed on the mounting portion 6, and under the cooperation of the threaded sleeve 501, the threaded sleeve 501 drives the driving block 5 to move along the axis of the adjusting screw 4. When the driving block 5 moves downward, the guide slope of the driving block 5 presses the guide slope of the fixing block 3 downward, so that the fixing block 3 is pressed to move transversely in the mounting groove 601, so that the fixing block 3 gradually abuts against the inner wall of the tool head 2. The plurality of fixing blocks 3 are arranged circumferentially around the axis of the mounting portion 6. When the driving block 5 is adjusted, the plurality of fixing blocks 3 can be simultaneously driven to move, thereby fixing the tool head 2 and ensuring the centering adjustment of the tool head 2 to ensure the working accuracy.

[0029] Specifically, as shown in Figure 2 , the end of the mounting portion 6 is provided with a groove 604, and the end of the adjusting screw 4 is located in the groove 604. The adjusting hole at the end of the adjusting screw 4 can be located in the groove 604, which facilitates adjustment and allows the end of the adjusting screw 4 to be stored in the groove 604, thereby facilitating the machining of the tool head 2.

[0030] Specifically, as shown in Figure 3 , the two sides of the mounting groove 601 are provided with sliding grooves 602, and the two sides of the fixing block 3 are provided with sliding blocks which are slidingly connected to the sliding grooves 602. Under the action of the sliding grooves 602, the movement of the fixing block 3 can be guided, so that the fixing block 3 can only move along the length direction of the sliding groove 602, thereby improving the limiting effect of the fixing block 3.

[0031] Specifically, as shown in Figure 1 , the side of the fixing block 3 close to the tool head 2 is an arc surface; since the inner wall surface of the tool head 2 is a complete circular structure, the side of the fixing block 3 close to the tool head 2 is an arc surface, which can increase the contact area between the fixing block 3 and the inner wall surface of the tool head 2, thereby increasing the fixing effect of the fixing block 3 on the tool head 2.

[0032] Specifically, as shown in Figure 2 , the end of the fixing block 3 is provided with a limiting block 301 which abuts against the tool head 2; the limiting block 301 extends laterally along the fixing block 3, so that the limiting block 301 is perpendicular to the fixing block 3. The limiting block 301 can axially limit the tool head 2, so that the tool head 2 can be more stably installed on the mounting portion 6, thereby ensuring the stability and improving the machining accuracy.

[0033] Based on the above scheme, as shown in Figure 3 Further comprising a plurality of springs 7, the mounting portion 6 is provided with a plurality of limiting grooves 603 corresponding to the plurality of fixing blocks 3, the plurality of springs 7 are respectively arranged in the plurality of limiting grooves 603, the fixing block 3 is provided with a connecting block 302, the connecting block 302 is clamped in the limiting groove 603 and abuts against the spring 7; when the adjusting screw 4 drives the driving block 5 to move downward and makes each fixing block 3 expand outward, the connecting block 302 of the fixing block 3 extrudes the spring 7 in the limiting groove 603, so that the connecting block 302 can be subjected to the force caused by the deformation of the spring 7, when the adjusting screw 4 drives the driving block 5 to move upward, the connecting block 302 can be reset under the action of the spring 7, drive the fixing block 3 to return to the mounting groove 601, make the fixing block 3 separate from the tool bit 2, facilitate the disassembly of the tool bit 2.

[0034] Meanwhile, as shown in Figure 3 The limiting groove 603 is fixedly provided with a limiting rod 701, the spring 7 and the connecting block 302 are sleeved on the limiting rod 701, the limiting rod 701 can better limit the connecting block 302 and the spring 7, not only ensure the movement track of the fixing block 3, but also make the spring 7 not be bent.

[0035] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all should be covered in the scope of the claims of the present application.
