[0002] In the field of mechanical processing, the eccentric bearing is a part with a special structure, and its processing accuracy and surface quality requirements are extremely high. The processing of the eccentric bearing involves precise boring of the inner arc surface, which is the key to ensure a good fit between the eccentric bearing and the mating shaft. Therefore, the inner arc processing of the eccentric bearing is particularly important. However, due to the special shape and processing requirements of the eccentric bearing, traditional turning tools are often difficult to meet its processing needs.

[0035] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in this application. Obviously, the embodiments described are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] Traditional automotive tool bars are usually fixed in design and are difficult to adapt to the processing of special parts such as eccentric bearings. Traditional tool bars lack sufficient adjustment flexibility and cannot adjust the position and angle of the tool according to actual needs. This makes it difficult to ensure the dimensional accuracy and shape accuracy of the inner hole when processing eccentric bearings, and is also not conducive to improving processing efficiency.

[0037] It should be noted that the eccentric bearings made of the vehicle tool bar for processing eccentric bearings in this application are preferably used on centerless grinders, and can also be used on other grinders, without specific limitation here.

[0038] Based on this, the present application provides a turning tool rod for processing eccentric bearings. The turning tool rod is provided with through slots and holes, as well as openings connected thereto, so that an adjustable boring tool can be flexibly placed in the slots and fixed by screws, so that the operator can accurately adjust the position of the adjustable boring tool according to the processing requirements, thereby greatly improving the processing accuracy of the inner hole of the eccentric bearing.

[0039] See also Figures 1 to 7 The present application provides a vehicle tool bar for processing eccentric bearings, comprising: a tool bar 1, a screw 2 and an adjustable boring tool 14; the tool bar 1 is provided with a through slot 11 and a through hole 15, and the through slot 11 and the through hole 15 are arranged perpendicular to each other; the through slot 11 is provided with an opening connected to the through hole 15; the adjustable boring tool 14 is placed in the through slot 11, and the screw 2 is placed in the through hole 15, and the screw 2 is used to press the adjustable boring tool 14 through the opening so that the adjustable boring tool 14 is fixed in the tool bar 1.

[0040] First, the role and function of each component are explained:

[0041] Tool bar 1: As the main structure of the entire lathe tool bar 1, the tool bar 1 provides a stable installation and support platform for the adjustable boring tool 14. The tool bar 1 can withstand the cutting force and vibration generated during the processing to ensure the stability of the processing.

[0042] Among them, the tool rod 1 is provided with a through slot 11 and a hole 15. The four corners of the through slot 11 are set as rounded corners. The slot 11 is used to accommodate and guide the movement of the adjustable boring tool 14. The hole 15 is used to insert the screw 2 to fix the adjustable boring tool 14 on the tool body 3.

[0043] Screw 2: Screw 2 is a fastener connecting the adjustable boring tool 14 and the tool arbor 1. Through its tightening action, the adjustable boring tool 14 is firmly fixed to the tool arbor 1. Screw 2 is inserted through the opening 15 in the tool arbor 1 and connected to the adjustable boring tool 14 through the opening in the slot 11. When screw 2 is tightened, the tightening force it generates presses the adjustable boring tool 14 tightly into the slot 11 of the tool arbor 1, preventing it from moving or shaking during the machining process.

[0044] Adjustable boring tool 14: This is a modular tool that actually performs the cutting process. It is placed in slot 11 of tool arbor 1. Adjusting its position within slot 11 changes its cutting position. Once the adjustable boring tool 14 is properly positioned, it is secured to tool arbor 1 with screws 2 to ensure stability during machining.

[0045] Specifically, the slot 11 and hole 15 on the tool bar 1 are arranged perpendicular to each other, allowing the adjustable boring tool 14 to move and adjust along a certain direction within the slot 11. The shape and size of the slot 11 match those of the adjustable boring tool 14, ensuring that the adjustable boring tool 14 can be smoothly inserted into the slot 11 and is not obstructed during movement and adjustment. The position and size of the hole 15 also match those of the screw 2, ensuring that the screw 2 can be smoothly inserted into the hole 15 and connected to the adjustable boring tool 14 through the opening, thereby securing the adjustable boring tool 14 to the tool body 3.

[0046] Optionally, the adjustable boring tool 14 includes a tool body 3 , a tool head 4 and an alloy blade 6 ; the alloy blade 6 is welded to the tool head 4 , and the tool head 4 is detachably mounted on both sides of the tool body 3 .

[0047] In the embodiment of the present application, the adjustable boring tool 14 is a key component for processing eccentric bearings. The adjustable boring tool 14 consists of three parts: a tool body 3, a tool head 4 and an alloy blade 6. Among them, the tool body 3 is the main structure of the adjustable boring tool 14, which provides a basis for installation and support for the tool head 4.

[0048] The blade body 3 is made of high-strength and high-rigidity materials, such as alloy steel or tungsten carbide, to ensure its stability and durability during use. The blade heads 4 are detachably mounted at both ends of the blade body 3, and the alloy blades 6 are welded to the blade heads 4.

[0049] The cutter head 4 is designed to be detachable and is made of wear-resistant and heat-resistant alloy material to ensure good cutting performance and durability during the processing. The cutter head 4 is firmly installed on the cutter body 3 to ensure that it will not loosen or fall off during the processing.

[0050] It should be noted that the position of the cutter head 4 can be adjusted according to processing requirements. By changing the installation position of the cutter head 4 on the cutter body 3, the cutting diameter and cutting depth of the adjustable boring tool 14 can be changed. The alloy blade 6 is welded to the cutter head 4 to ensure that the alloy blade 6 will not fall off or loosen during the processing. The alloy blade 6 can withstand high-speed cutting and high-temperature environments and maintain stable cutting performance.

[0051] In summary, the tool body 3, tool head 4 and alloy blade 6 in the adjustable boring tool 14 cooperate with each other to complete the precision processing of the eccentric bearing. The tool body 3 provides the basis for installation and support, the tool head 4 can be replaced or adjusted according to the processing requirements, and the alloy blade 6 actually performs the cutting processing, so that the adjustable boring tool 14 can adapt to the processing requirements of eccentric bearings of different specifications and shapes, improve the processing accuracy and efficiency, and ensure the stability and durability during the processing.

[0052] Optionally, a first mounting area 8 and a second mounting area 9 are provided on both sides of the blade body 3, the first mounting area 8 and the second mounting area 9 are symmetrically arranged up and down, and the blade head 4 is detachably installed in the first mounting area 8 and the second mounting area 9.

[0053] In the embodiment of the present application, the cutter body 3 serves as the main structure of the adjustable boring tool 14, and can provide a basis for installation and support for the cutter head 4 and the alloy blade 6. Specifically, a first installation area 8 and a second installation area 9 are provided on both sides of the cutter body 3. The first installation area 8 and the second installation area 9 are both provided with rounded corners. The two installation areas are symmetrically arranged up and down. The cutter head 4 is detachably installed in the first installation area 8 or the second installation area 9 of the cutter body 3 by means of a threaded connection, so that the cutter head 4 can be replaced or adjusted according to processing requirements to adapt to eccentric bearings of different specifications and shapes.

[0054] It should be noted that two cutter heads 4 or one cutter head 4 can be installed on the cutter body 3, which is not specifically limited here and can be set according to actual conditions.

[0055] Optionally, a positioning threaded hole 7 and a through waist-shaped countersunk hole 5 are provided on the cutter head 4, and the through waist-shaped countersunk hole 5 and the positioning threaded hole 7 are arranged perpendicular to each other. The first mounting area 8 and the second mounting area 9 are both provided with mounting threaded holes. The cutter head 4 is installed in the first mounting area 8 and the second mounting area 9 by a clamping screw 12 and a positioning screw 13. The clamping screw 12 is connected to the mounting threaded hole through the through waist-shaped countersunk hole 5, and the positioning screw 13 is connected to the cutter body 3 through the positioning threaded hole.

[0056] In the embodiment of the present application, a positioning threaded hole 7 and a through waist-shaped countersunk hole 5 are provided on the cutter head 4. The two holes are arranged perpendicular to each other. The through waist-shaped countersunk hole 5 is used to accommodate a clamping bolt 12 and provide sufficient space for it so that the bolt head of the clamping bolt can sink into the waist-shaped countersunk hole 5 and will not protrude from the surface of the cutter head 4, thereby avoiding interference with the workpiece during the processing process. The positioning threaded hole 7 is used to accommodate a positioning screw 13. The clamping bolt 12 and the positioning screw 13 are used together to connect the cutter head 4 to the cutter body 3.

[0057] The cutter body 3 is provided with a first mounting area 8 and a second mounting area 9, both of which are used to mount the cutter head 4. Each mounting area is provided with a mounting threaded hole. The mounting threaded holes in the first mounting area 8 and the second safety area 9 correspond to the waist-shaped countersunk holes 5 extending through the cutter head 4. The clamping bolt 12 is connected to the mounting threaded hole in the cutter body 3 through the waist-shaped countersunk holes 5 extending through the cutter head 4. When the clamping bolt 12 is tightened, the tightening force it generates firmly presses the cutter head 4 against the mounting area of ​​the cutter body 3, ensuring that the cutter head 4 does not move or shake during the machining process. The positioning screw 13 is connected to one side of the cutter body 3 through the positioning threaded hole 7 on the cutter head 4. The positioning screw 13 further secures the cutter head 4, ensuring its stability and reliability during the installation process. Through the combined action of the clamping bolt 12 and the positioning screw 13, the cutter head 4 is firmly mounted on the cutter body 3 and can withstand the cutting forces and vibrations generated during the machining process.

[0058] To sum up, through the combined action of the clamping bolt 12 and the positioning screw 13, the cutter head 4 can be firmly mounted on the cutter body 3, thereby withstanding the cutting force and vibration generated during the machining process. At the same time, the through waist-shaped countersunk hole 5 prevents the bolt head from protruding from the surface of the cutter head 4, thereby avoiding interference with the eccentric bearing.

[0059] Optionally, V-shaped inclined surfaces 10 are provided on both sides of the blade body 3, and the inclination angle of the V-shaped inclined surface 10 is set to a preset angle. The blade body 3 is placed in the through slot 11, and the screw 2 presses the V-shaped inclined surface on the blade body 3 through the through slot 11 and the opening. A cone structure is provided on the screw 2, and the angle of the cone structure is adapted to the preset angle of the V-shaped inclined surface 10.

[0060] In the embodiment of the present application, in order to ensure the stable installation of the blade body 3 in the slot 11 of the blade rod 1 and enable the screw 2 to firmly fix the blade body 3, the V-shaped inclined surface 10 provided on the blade body 3 is adapted to the conical structure on the screw 2.

[0061] Specifically, a V-shaped inclined surface 10 is provided on both sides of the blade body 3. The V-shaped inclined surface 10 is V-shaped, and its two side surfaces form a certain angle, that is, an inclination angle. The inclination angle of the V-shaped inclined surface 10 is preferably set to 130°, but can also be set to other angles, which is not specifically limited here.

[0062] The conical structure on screw 2 is located near the head of screw 2. Its shape matches the V-shaped inclined surface 10 and is also inclined at a certain angle. When screw 2 is screwed into opening 15 of tool arbor 1 and passes through the opening in slot 11 to contact cutter body 3, the conical structure tightly abuts against V-shaped inclined surface 10, forming a stable, secure connection. Because the angle of the conical structure matches the angle of the V-shaped inclined surface 10, screw 2 generates sufficient tightening force to securely fix cutter body 3 in slot 11 of tool arbor 1. This fit ensures the stability of cutter body 3 during machining, preventing it from moving or shaking under the influence of cutting forces or vibrations.

[0063] Among them, the first installation area and the second installation area are both provided with rounded corners, and the four corners of the through slots are set as rounded corners. The purpose of setting the rounded corners is to facilitate processing and ensure processing quality. At the same time, interference can be avoided during the assembly process. The position of the rounded corners can also be used to accommodate the edge and corner areas of the cutter head to avoid direct contact.

[0064] It should be noted that the above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of the present application.
