Description

Technical Field

[0001] This utility model relates to the field of roughing tooling technology, specifically to a roughing tooling. Background Technology

[0002] Rough turning fixtures are specialized equipment used for workpiece clamping and positioning in machining. Based on their application scenarios and functions, they can be divided into machining fixtures and testing fixtures, and are widely used in automobile manufacturing, electronics, logistics, and other fields. Machining fixtures, such as VL-type universal joint outer star wheel rough turning fixtures, mainly solve the problem of clamping stability for complex parts; testing fixtures, such as rough handling test devices, are used to simulate product durability testing under extreme environments.

[0003] Existing equipment has difficulty ensuring consistent axial machining allowance when machining rotor hubs, and the machining of the inner and outer end faces of the rotor hubs needs to be carried out in stages, which increases the machining time of the rotor hubs. Furthermore, deviations are prone to occur during the multi-stage machining process, thus affecting the quality of the rotor hubs. Utility Model Content

[0004] The purpose of this invention is to provide a roughing tool to solve the problems mentioned in the background art.

[0007] The 10-inch hydraulic internal support chuck has a first positioning groove and a second positioning groove evenly distributed throughout its inner side. A circular groove is formed at the center of the inner side of the 10-inch hydraulic internal support chuck, and a through groove is formed at the center of the circular groove. Adjustment grooves are evenly distributed on the outer side of the 10-inch hydraulic internal support chuck.

[0008] A further improvement of this utility model is that the second positioning groove is located on both sides of the first positioning groove, and the second positioning groove is also located on both sides of the adjustment groove.

[0009] Using the above technical solution, the position of the three-jaw modified fixture on the side of the ten-inch hydraulic internal support chuck can be adjusted by adjusting the groove, that is, adjusting the size of the notch.

[0010] A further improvement of the present invention is that the limiting component includes a three-jaw modified clamp and a V-shaped limiting block clamp disposed on the outside of a 10-inch hydraulic inner support chuck. The outer edge of the three-jaw modified clamp is provided with a first slot, the inner edge of the three-jaw modified clamp is provided with a second slot, the inner edge of the three-jaw modified clamp is notched, the center position of the outer side of the V-shaped limiting block clamp is provided with a third slot, and the outer edge of the V-shaped limiting block clamp is provided with a fourth slot.

[0011] By adopting the above technical solution, the position of the missing groove is adjusted by changing the position of the modified three-jaw fixture on the adjustment groove, thereby adjusting the size of the missing groove at the connection of the four sets of modified three-jaw fixtures.

[0012] A further improvement of the present invention is that: the V-shaped limiting block clamp is located on the outside of the three-jaw modified clamp; the first slot and the second slot are both connected to the adjustment slot; the corner of the V-shaped limiting block clamp is located on the inside of the first positioning slot; and the fourth slot is connected to the second positioning slot.

[0013] Using the above technical solution, the V-shaped limiting block clamp can be fixed to one side of the 10-inch hydraulic internal support chuck by the bolts placed in the fourth slot and the second positioning slot. The three-jaw modified clamp can be restricted between the V-shaped limiting block clamps by the adjusting slot. The three-jaw modified clamp can be positioned by the bolts placed in the first slot and the second slot. The outer end of the V-shaped limiting block clamp acts on the inner wall of the rotor hub body to perform outer diameter machining on the inner wall of the rotor hub body.

[0014] A further improvement of the present invention is that the rotor hub assembly includes a rotor hub body disposed on the outside of a 10-inch hydraulic inner support chuck, a fifth slot is uniformly opened through the outer edge of the inner end of the rotor hub body, a spindle is fixedly connected to the center of the inner end of the rotor hub body, and a sixth slot is uniformly opened through the inner end of the rotor hub body.

[0015] A further improvement of the present invention is that the sixth slot is located on the outside of the mandrel, the mandrel is connected to the notched slot, and the sixth slot is connected to the third slot.

[0016] By adopting the above technical solution, the mandrel is placed inside the notch, so that the notch can be processed on the mandrel. By changing the size of the notch, different steps can be formed by the notch acting on the mandrel.

[0017] A further improvement of this utility model is that the fifth slot is connected to the first positioning slot.

[0018] Using the above technical solution, the 10-inch hydraulic internal support chuck can be limited and fixed by the external bolts in the fifth slot and the first positioning slot.

[0019] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0020] 1. This utility model provides a rough machining fixture, which uses a limiting component, a modified three-jaw fixture, a first slot, a second slot, a V-shaped limiting block fixture, a third slot, and a fourth slot to perform outer circle machining on the inner wall of the rotor hub body by the outer end of the V-shaped limiting block fixture acting on the inner wall of the rotor hub body. The position of the modified three-jaw fixture is changed by adjusting the slot to adjust the size of the missing slot.

[0021] 2. This utility model provides a rough machining fixture, which uses a rotor hub assembly, rotor hub body, fifth slot, sleeve and sixth slot to cooperate. The sleeve is placed inside the notch, so that the notch can form different steps for the sleeve when it is placed in different sizes. The mandrel is clamped by the through slot, and the axial position is positioned by the blank end face. This ensures that the axial machining allowance of the product is consistent during the processing, that is, the machined outer circle is concentric with the mandrel in the middle of the clamp. After clamping and axially positioning the product, the inner and outer end faces, i.e. the outer circle and the step, can be machined in one go, thereby ensuring the form and position tolerance requirements of the product.

[0033] The limiting component 2 includes a three-jaw modified clamp 21 and a V-shaped limiting block clamp 24 disposed on the outside of the 10-inch hydraulic inner support chuck 1. The outer edge of the three-jaw modified clamp 21 is provided with a first slot 22, the inner edge of the three-jaw modified clamp 21 is provided with a second slot 23, the inner edge of the three-jaw modified clamp 21 is notched 27, the center position of the outer side of the V-shaped limiting block clamp 24 is provided with a third slot 25, and the outer edge of the V-shaped limiting block clamp 24 is provided with a fourth slot 26.

[0034] The V-shaped limiting block clamp 24 is located outside the three-jaw modified clamp 21. The first slot 22 and the second slot 23 are both connected to the adjustment slot 15. The corner of the V-shaped limiting block clamp 24 is located inside the first positioning slot 11. The fourth slot 26 is connected to the second positioning slot 12.

[0035] In this embodiment, the position of the modified three-jaw clamp 21 on the side of the 10-inch hydraulic internal support chuck 1 can be adjusted by adjusting the groove 15, that is, adjusting the size of the notch 27. By changing the position of the modified three-jaw clamp 21 on the adjusting groove 15, the position of the notch 27 is adjusted, thereby adjusting the size of the notch 27 at the connection of the four sets of modified three-jaw clamps 21. The V-shaped limiting block clamp 24 can be fixed on one side of the 10-inch hydraulic internal support chuck 1 by the bolts externally placed in the fourth slot 26 and the second positioning slot 12. The modified three-jaw clamp 21 can be restricted between the V-shaped limiting block clamps 24 by adjusting the groove 15. The modified three-jaw clamp 21 can be positioned by the bolts externally placed in the first slot 22 and the second slot 23. The outer end of the V-shaped limiting block clamp 24 acts on the inner wall of the rotor hub body 31 to perform outer circle machining on the inner wall of the rotor hub body 31.

[0036] Example 2

[0037] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the rotor hub assembly 3 includes a rotor hub body 31 disposed on the outside of the 10-inch hydraulic inner support chuck 1, a fifth slot 32 is uniformly opened through the outer edge of the inner end of the rotor hub body 31, a spindle 33 is fixedly connected to the center position of the inner end of the rotor hub body 31, and a sixth slot 34 is uniformly opened through the inner end of the rotor hub body 31.

[0039] In this embodiment, the mandrel 33 is placed inside the notch 27, so that the notch 27 can be processed on the mandrel 33. By changing the size of the notch 27, different steps can be formed on the mandrel 33. The ten-inch hydraulic inner support chuck 1 can be limited and fixed by the external bolt in the fifth slot 32 and the first positioning slot 11.

[0040] The working principle of this roughing tooling will be explained in detail below.

[0041] like Figure 1-5 As shown, when the tooling needs to be processed, the mandrel 33 is first clamped through the through slot 14, and the axial position is positioned by the blank end face to ensure that the axial machining allowance is consistent during the processing of the product, that is, the outer circle being processed is concentric with the mandrel 33 in the clamping middle. The outer end of the V-shaped limiting block clamp 24 acts on the inner wall of the rotor hub body 31 to process the outer circle of the inner wall of the rotor hub body 31. By placing the mandrel 33 inside the notch 27, the notch 27 can process the mandrel 33. The position of the three-jaw modified clamp 21 is changed by adjusting the slot 15 to change the size of the notch 27, so that the notch 27 can form different steps on the mandrel 33. After clamping and axially positioning the product, the inner and outer end faces, i.e., the outer circle and the steps, can be processed in one go to ensure the form and position tolerance requirements of the product.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
