Description

Technical Field

[0001] The utility model relates to a locking mechanism, in particular to a spinning turret locking mechanism, and belongs to the technical field of IPC classification No. B23B. Background Art

[0002] When the spinning turret assembled on the existing lathe rotates to change tools, there is a distance of 1mm between the turret main box and the turret base to ensure that the bottom of the turret main box does not contact the turret base when rotating. When one of the tools is in use, the turret main box is locked with the turret base. This ensures the stability of the tool during use, thereby ensuring the accuracy of lathe processing.

[0003] At present, in order to lock the turret main box and the turret base, the structure adopted is roughly to insert the locking part into the positioning hole. In this kind of setting, the locking part has a large exposed part and poor anti-twisting ability. The life of the locking structure between the turret main box and the turret base will be affected with the increase of use, which will reduce the reliability of the turret. Summary of the invention

[0004] The purpose of the utility model is to solve the above-mentioned problems and provide a spinning turret locking mechanism with strong anti-twisting ability of the corresponding mechanism after the turret main box and the turret base are locked.

[0005] The technical solution to the problem to be solved by the utility model is as follows:

[0006] The spinning turret locking mechanism includes a main box, a main shaft arranged inside the main box and a base, and is characterized in that: on the docking surface between the main box and the base, a plurality of male card blocks are arranged in a ring array with the main shaft as the center, and corresponding female card blocks are arranged on the base corresponding to the gaps between the male card blocks. When the main box and the base are docked, the male card blocks are inserted into the gaps between the female card blocks, and the male and female card blocks are combined to form a locking ring.

[0007] Preferably, an outer wall is further provided on the outer side of the annular array of male card blocks, and an outer wall and / or an inner wall with a sealing groove are provided on the base corresponding to the outer side of the outer wall.

[0009] Preferably, a chamfer is provided at the insertion point of the male card block and / or the female card block.

[0010] Preferably, in the male and female card blocks, the volume of the male card block is larger than that of the female card block or the volume of the female card block is larger than that of the male card block.

[0011] The beneficial effects of the utility model are as follows:

[0012] Compared with the prior art, the utility model successfully improves the anti-torsion capability of the spinning turret during operation by setting a ring-shaped array of male card blocks and a ring-shaped array of female card blocks with matching gaps on the docking surface between the main box and the base, so that the turret can remain stable during operation and can always maintain good anti-torsion performance even when subjected to external torque. The gaps between the male card blocks and the female card blocks match each other, ensuring that the two can directly form a solid locking ring after docking and plugging.

[0017] The following will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, that is, a large number of specific details are given to provide a more thorough understanding of the present invention. However, for those skilled in the art, the present invention can be implemented without one or more of these details. In these examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0018] It should be understood that the present invention can be implemented in different forms and should not be construed as being limited to the embodiments presented herein. Therefore, they are only used as examples and cannot be used to limit the scope of protection of the present invention.

[0019] In addition, it should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0020] See also Figures 1 to 3 The spinning turret locking mechanism mainly includes a main box body 1 of the turret, a spindle 2 arranged inside the main box body 1, and a structure composed of relevant parts of a base 3. On the docking surface between the main box body 1 and the base 3, a plurality of male card blocks 4 are designed in a ring array with the spindle 2 as the center. The gaps between these male card blocks 4 are carefully calculated and designed to match the rotation angle of the turret, and they are docked and plugged with corresponding female card blocks 5 arranged on the base 3.

[0021] When the main box 1 is docked with the base 3, the male block 4 can be smoothly inserted into the gap 6 between the female blocks, and the two engage with each other in the direction of rotation of the spindle 1 to form a complete locking ring. This design makes the spinning turret locking mechanism have excellent stability and safety when working, and effectively prevents the turret from displacement or vibration during operation.

[0022] Furthermore, as an improvement to the present invention, an outer wall 7 is provided outside the annular array of male card blocks 4, and a barrier wall 8 having an outer wall and / or an inner wall with a sealing groove 81 is provided on the base 3 corresponding to the outer side of the outer wall 7.

[0023] In implementation, an outer wall 7 is cleverly set outside the annular array of the male card block 4, and then a barrier wall 8 is set by the base 3 to protect the male card block 4 and the female card block 5 on the base 3 inside, and when the main box 1 is separated from the base 3, it can prevent debris from entering between the male card block 4 and the female card block 5, affecting the docking and plugging of the male card block 4 and the female card block 5 and destroying the stability. The sealing and dustproof and waterproof capabilities of the spinning turret locking mechanism are further improved.

[0024] In addition, the barrier wall 8 can also be set as a composite structure with a sealing groove 81 on the contact surface with the outer wall 7, so that during operation, it can effectively prevent coolant, cuttings, dust and other debris from entering the interior of the mechanism, protecting the yin and yang blocks and even the main shaft part from wear and corrosion.

[0025] Furthermore, as an improvement to the present invention, the male card block 4 is cleverly arranged in a step surface 9 formed by the inward depression of the main box body 1, and an annular isolation groove is also provided on the outer side of the step surface 9, and a matching isolation wall is provided on the base corresponding to the annular isolation groove.

[0026] When implemented, the annular isolation groove and the matching inserted isolation wall on the base cooperate with each other to form a complete isolation system. This design is intended to reduce the contact of the spinning turret locking mechanism with external impurities during operation, reducing the risk of wear and failure. This combined design achieves excellent locking performance and isolation effect.

[0027] Furthermore, as an improvement to the present invention, a chamfer is provided at the insertion position of the male card block 4 and / or the female card block 5 .

[0028] During implementation, it is convenient for the female and male card blocks to be butted and plugged together.

[0029] Further, as an improvement to the present invention, in the male and female clamping blocks, the volume of the male clamping block is larger than that of the female clamping block or the volume of the female clamping block is larger than that of the male clamping block.

[0030] In the design of the male and female clamping blocks of the spinning turret locking mechanism, the volume relationship between the male and female clamping blocks is cleverly adjusted according to the mechanical principles and actual application requirements. This design aims to achieve good complementarity and synergy between the male and female clamping blocks during the locking process, and further improve the performance of the spinning turret locking mechanism.

[0031] According to specific application scenarios and performance requirements, the volume of the male card block 4 is either greater than the volume of the female card block 5, or the volume of the female card block 5 is greater than the volume of the male card block 4. This volume difference design has the following advantages:

[0032] Improved locking force: The larger male block 4 (or female block 5) can generate greater friction during the locking process, thereby improving the locking force. This is crucial to ensure the stability and safety of the spinning turret under high-speed rotation conditions.

[0033] Good complementarity: The difference in volume between the male block 4 and the female block 5 enables them to better complement each other during the locking process. When the turret is subjected to external shock or vibration, the complementary effect between the male block 4 and the female block 5 helps to maintain the stability of the locking force, so that the turret always remains in the correct position.

[0034] Prevent axial movement: The larger male block 4 (or female block 5) generates greater resistance in the axial direction, effectively preventing the turret from moving in the axial direction. This plays an important role in ensuring the precision and processing quality of the spinning turret.

[0035] Improve wear resistance: The difference in volume between the male clamp block 4 and the female clamp block 5 enables the two to better disperse the load during the locking process, reduce the wear rate of a single part, and thus improve the overall service life of the spinning turret locking mechanism.

[0036] In summary, by cleverly adjusting the volume relationship between the male clamping block 4 and the female clamping block 5, the spinning turret locking mechanism improves the locking performance, stability and safety while also having excellent wear resistance and service life.
