[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement and ensure their rotation accuracy. Rolling bearings are generally composed of four parts: an outer ring, an inner ring, rolling elements and a cage.

[0003] The inner and outer rings are processed by lathes, and multiple turning tools are needed to be used in sequence during the processing. Therefore, different turning tools need to be constantly replaced during the processing, which greatly prolongs the processing time and greatly reduces production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0034] The following is a further detailed description of 1-4 of this application in conjunction with the accompanying drawings.

[0035] The embodiment of the present application discloses a composite turning tool for machining inner and outer rings of a bearing.

[0036] Example 1

[0037] Reference Figure 1 The composite turning tool for processing the inner and outer rings of the bearing includes a tool holder 1 and a tool 2. A plurality of tools 2 are arranged at intervals along the length direction of the tool holder 1. The plurality of tools 2 are also arranged at intervals according to the processing sequence and can process the products in sequence. Therefore, the moving path of the tool 2 is shorter during the processing, and the distance between the plurality of tools 2 and the tool holder 1 gradually changes according to the processing sequence, so that a single tool 2 can avoid other tools 2 when processing.

[0038] The tool 2 includes a tool rod 21 and a blade 22. One end of the tool rod 21 is fixedly mounted on the side wall of the tool handle 1, and a fixing groove is opened at the end of the tool rod 21 away from the tool handle 1. The blade 22 is clamped and mounted on the fixing groove and fixed by a fixing screw, so that the blade 22 can be replaced. The tool rod 21 has different lengths and the distance between each blade 22 and the tool handle 1 is different, so that other tools 2 can be avoided when a single tool 2 is processed.

[0039] The working principle of the embodiment of the present application is as follows:

[0040] Processing is performed sequentially by using a plurality of different tools 2 without changing tools, thus saving the time spent on tool changing. Moreover, the installation sequence of the tools 2 is also performed according to the processing sequence, thereby making the moving path of the tools 2 shorter during processing. At the same time, the distances between the blades 22 at different positions and the tool holder 1 are designed to be different, so that a single tool 2 will not interfere with other tools 2 during processing, making the operation more stable, thereby greatly improving the production efficiency.

[0041] Example 2

[0042] Reference Figure 2 The difference between this embodiment and embodiment 1 is that the multiple cutting tools 2 can be detachably mounted on the tool handle 1.

[0043] Reference Figure 2 and Figure 3 A plurality of mounting grooves 3 are provided on the side wall of the tool handle 1 at intervals along the length direction of the tool handle 1. The plurality of mounting grooves 3 are arranged one by one corresponding to the plurality of knives 2. The mounting grooves 3 are for the tool rod 21 to be inserted and positioned. The mounting grooves 3 include a rotating portion 31 with a circular cross-section and a positioning portion 32 with a regular polygonal cross-section. The regular polygon is a regular hexagon. The rotating portion 31 and the positioning portion 32 are arranged at intervals along the length direction of the tool rod 21.

[0044] The tool rod 21 includes a rotating section 23 rotatably connected to the rotating part 31 and a positioning section 24 plugged into the positioning part 32 for positioning, and the rotating section 23 and the positioning section 24 are arranged at intervals along the length direction of the tool rod 21; the axis of the rotating part 31 and the center line of the positioning part 32 coincide, and the projection of the positioning part 32 along the axis of the rotating part 31 is located in the rotating part 31, so after the tool rod 21 is pulled to disengage the positioning section 24 from the positioning section 32, the positioning section 24 is also moved into the rotating part 31 and can rotate on the rotating part 31, so as to adjust the angle of the tool 2. After the adjustment is completed, the tool 2 is pushed back so that the positioning section 24 is plugged and installed on the positioning part 32 for positioning, thereby realizing the adjustment of the angle of the tool 2.

[0045] The depths of the multiple installation grooves 3 are different, and the depths of the multiple installation grooves 3 gradually change along the length direction of the tool handle 1 and the change range is consistent. Therefore, the lengths of the multiple tool rods 21 are consistent. The different depths of the installation grooves 3 are used to achieve different distances between the blade 22 and the tool handle 1, so that other tools 2 can be avoided when a single tool 2 is processed, so that there is no interference when multiple tools 2 are processed.

[0046] Reference Figure 2 and Figure 3 A clamping hole 11 penetrating the mounting groove 3 is provided at one end of the tool handle 1, and clamping pieces 12 for clamping the tool 2 for positioning are formed on both sides of the clamping hole 11. The tool handle 1 is made of metal material, so that the two clamping pieces 12 have a certain resilience. The two clamping pieces 12 are provided with a clamping assembly 4 for driving the two clamping pieces 12 to approach each other. After the clamping assembly 4 is unlocked, the two clamping pieces 12 move away from each other under the action of the resilience, so that the tool 2 can be removed or the angle of the tool 2 can be adjusted.

[0047] The clamping assembly 4 includes a clamping screw 41 and a clamping nut 42. The clamping screw 41 passes through the two clamping pieces 12 in sequence, and the clamping nut 42 is threadedly connected to the clamping screw 41, so that the two clamping pieces 12 are close to each other to clamp the tool 2. The clamping screw 41 is screwed in the opposite direction, so that the two clamping pieces 12 are separated from each other under the action of the rebound force. A clamping groove 43 is provided on the clamping piece 12, and the clamping nut 42 is inserted and installed in the clamping groove 43 for positioning, so that when the clamping screw 41 rotates, the clamping nut 42 will not be driven to rotate.

[0048] The working principle of the embodiment of the present application is as follows:

[0049] When adjustment is required, turn the clamping screw 41 to loosen the clamping of the tool 2, pull the tool rod 21 to disengage the positioning section 24 from the positioning portion 32, rotate the tool rod 21, and after the adjustment is completed, push the tool rod 21 back to make the positioning section 24 and the positioning portion 32 plug and cooperate, turn the clamping screw 41 to clamp the tool 2, so that the angle of the tool 2 can be adjusted, thereby further improving production efficiency.

[0050] At the same time, the tool 2 can be removed and replaced with a tool 2 with different requirements, so as to adapt to different processing requirements of the product, thereby improving the convenience of product processing and improving production efficiency.

[0051] Example 3

[0052] Reference Figure 4 The difference between this embodiment and embodiment 2 is that the depths of the multiple installation grooves 3 are the same, and a positioning member 5 for positioning the position of the tool 2 is provided on the tool handle 1. The positioning member 5 is a positioning screw threadedly connected to the upper surface of the tool handle 1 and pressed against the tool rod 21.

[0053] The working principle of the embodiment of the present application is as follows:

[0054] The positioning screw is turned away from the tool rod 21, and then the tool rod 21 is moved. After the movement is completed, the positioning screw is turned tightly against the tool rod 21 for positioning, thereby adjusting the position of the tool 2, and it can be infinitely adjusted according to needs within the adjustable range, which improves the convenience of adjusting the tool 2 and improves production efficiency.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
