Description

Technical Field

[0001] This utility model relates to the field of machining, specifically to a radial support frame structure for an automatic machining equipment for slender shafts. Background Technology

[0002] In the machining of slender shaft parts (such as guide rods and lead screws), in order to provide continuous radial support to the slender shaft to counteract the cutting force, prevent the workpiece from bending deformation and vibration due to excessive length-to-diameter ratio, and improve the machining accuracy and surface quality of slender shaft parts, auxiliary devices such as follow post are often used to radially support the rotating workpiece. Existing follower posts and other auxiliary radial support tools generally use two to three support claws to make contact with the workpiece surface, forming multi-point dynamic constraints. This support method results in direct hard contact between the follower post and the workpiece surface. During the movement of the follower post, it may cause damage to the workpiece surface, affecting the surface quality of the workpiece. Furthermore, when the surface quality of the workpiece is poor, jamming may occur between the follower post and the workpiece. In addition, the support points of existing follower posts for the workpiece cannot be adjusted, which is inconvenient for users. Utility Model Content

[0003] To solve the above-mentioned technical problems, a radial support frame structure for an automatic machining equipment for slender shafts is provided, which solves the technical problems of existing follower posts wearing down the workpiece surface, jamming between the follower post and the workpiece surface, and the inability to adjust the support position of the follower post on the workpiece.

[0004] To achieve the above objectives, the following solutions are provided: A radial support frame structure for an automatic machining equipment for slender shafts includes a base, a support cantilever, several support modules, and several adjustment modules. The adjustment modules are evenly installed on the support cantilever, and the adjustment modules are adapted to the support modules. The support modules are installed at the adjustment modules. The adjustment module includes a threaded sleeve, a connecting sleeve, and a guide sleeve. The guide sleeve is fixedly installed inside the support cantilever and passes through the support cantilever. A connecting sleeve is threadedly installed on the outer wall of the support cantilever. One end of the threaded sleeve is rotatably installed inside the connecting sleeve. The threaded sleeve and the guide sleeve are coaxially arranged and communicate with each other. An internal threaded hole is provided inside the threaded sleeve. The support module includes a mounting base, ball bearings, a guide rod, and an adjusting screw. The outer wall of the mounting base is fixedly connected to one end of the guide rod. The guide rod is adapted to a guide sleeve. The other end of the guide rod is fixedly connected to one end of the adjusting screw. The guide rod is inserted into the guide sleeve. The adjusting screw is screwed into the inner threaded hole of the threaded sleeve. Two mounting cavities are opened on the side of the mounting base away from the guide rod. The mounting cavities are adapted to the ball bearings. Ball bearings are embedded in both mounting cavities. The guide rod is coaxial with the axis of symmetry of the two ball bearings and the center of the support cantilever.

[0005] Furthermore, the supporting cantilever has an arc-shaped structure.

[0006] Furthermore, the mounting base is adapted to the inner wall of the support cantilever, so that the mounting base can fit against the inner side of the support cantilever.

[0007] Furthermore, the through hole of the guide sleeve has a square structure.

[0008] Furthermore, the mounting base is provided with an oil cavity, which is connected to the mounting cavity. The surface of the mounting base is provided with an oil injection hole, which is connected to the oil cavity. A rubber plug is provided at the oil injection hole.

[0009] Furthermore, the base includes a fixed seat and a connecting seat, with the connecting seat provided on the fixed seat and fixedly connected to one end of the supporting cantilever.

[0010] The working principle and advantages of this utility model are as follows: The radial support frame structure of this slender shaft automatic processing equipment is fixedly installed at the corresponding processing equipment through a fixed seat. Then, the corresponding support modules are installed at the predetermined adjustment modules as needed, so as to meet the support of the support frame structure for different positions of the shaft workpiece under various conditions. The ball bearings of the support module are adjusted to abut against the surface of the shaft workpiece through the adjustment module. During the relative movement between the support frame structure and the shaft workpiece, the ball bearings are in direct contact with the shaft workpiece, which can effectively reduce the friction between the shaft workpiece and the support frame structure. While meeting the radial support of the shaft workpiece, it makes the relative movement between the support frame structure and the shaft workpiece more stable and smooth, and reduces the possibility of damage to the surface of the shaft workpiece.

[0013] The following detailed explanation illustrates the specific implementation methods: like Figures 1 to 2 As shown: A radial support frame structure for an automatic machining equipment for slender shafts includes a base, which includes a fixed seat 1 and a connecting seat 2. The fixed seat 1 is provided with the connecting seat 2. The fixed seat 1 is used to install the support frame structure at the corresponding automatic machining equipment for slender shafts (such as a lathe). The equipment also includes a support cantilever 3 with several support modules and several adjustment modules. The connecting seat 2 is fixedly connected to one end of the support cantilever 3. The support cantilever 3 has an arc-shaped structure with an opening so that the shaft workpiece can be placed into the center of the support cantilever 3, and at the same time, it is convenient for the cutting tool to process the shaft workpiece. The adjustment modules are evenly installed on the support cantilever 3. The adjustment modules are adapted to the support modules. The support modules are installed at the adjustment modules. The support modules can be disassembled at the support modules so that the support modules can be installed at different adjustment modules, thereby providing radial support for the slender shaft on the machining equipment at different positions and angles. The adjustment module includes a threaded sleeve 4, a connecting sleeve 5, and a guide sleeve 11. The guide sleeve 11 is fixedly installed inside the support cantilever 3 and passes through the support cantilever 3. The connecting sleeve 5 is threadedly installed on the outer wall of the support cantilever 3. One end of the threaded sleeve 4 is rotatably installed inside the connecting sleeve 5, so that the threaded sleeve 4 will not detach from the connecting sleeve 5 and the support rod cantilever when rotating. The threaded sleeve 4 and the guide sleeve 11 are coaxially arranged and are connected to each other. The threaded sleeve 4 is provided with an internal threaded hole 14. The support module includes a mounting base 6, ball bearings 10, guide rod 12, and adjusting screw 13. The outer wall of the mounting base 6 is fixedly connected to one end of the guide rod 12. The guide rod 12 is adapted to the guide sleeve 11. The through hole of the guide sleeve 11 is square, allowing the guide rod to move at the guide sleeve 11 without rotating. The other end of the guide rod 12 is fixedly connected to one end of the adjusting screw 13. The guide rod 12 is inserted into the guide sleeve 11. The adjusting screw 13 is screwed into the inner thread hole 14 of the threaded sleeve 4. Under the limiting action of the guide sleeve 11 and the guide rod 12, the rotation of the threaded sleeve 4 can drive the mounting base 6 to move. Two mounting cavities 9 are opened on the side of the mounting base 6 away from the guide rod 12. The two mounting cavities 9 are arranged side by side. The mounting cavities 9 are adapted to the ball bearings 10. The ball bearings 10 are embedded in both mounting cavities 9. The guide rod 12 is coaxial with the axis of symmetry of the two ball bearings 10 and the center of the support cantilever 3. This allows the mounting base 6 and the two ball bearings 10 to move only radially along the support cantilever 3, thereby enabling the support modules to work together to provide radial support to the peripheral workpiece. Mounting base 6 is adapted to the inner wall of support cantilever 3, so that mounting base 6 can fit against the inner side of support cantilever 3.

[0014] The mounting base 6 is provided with an oil cavity 8, which is connected to the mounting cavity 9. The surface of the mounting base 6 is provided with an oil injection hole 7, which is connected to the oil cavity 8. A rubber plug is provided at the oil injection hole 7. Lubricating oil can be injected into the oil injection hole 7 and the oil cavity 8 through a syringe, so that the ball 10 moves more smoothly relative to the shaft workpiece.

[0015] The specific implementation process is as follows: When using the radial support frame structure of this slender shaft automatic machining equipment, firstly, install the support frame structure on machining equipment such as a lathe via the fixed seat 1. Then, install each support module to the appropriate adjustment module. Insert the guide rod 12 and the screw into the guide sleeve 11 and the threaded sleeve 4. By rotating the threaded sleeve 4, the inner threaded hole 14 of the threaded sleeve 4 engages with the adjusting screw 13. Then, install the shaft workpiece to be machined into the machining equipment, so that the shaft workpiece enters from the opening of the support cantilever 3 to the center position of the support cantilever 3. Then, rotate the threaded sleeve 4, which drives the adjusting screw 13 to move. The screw pushes the mounting seat 6 toward the shaft workpiece through the guide rod 12, so that the balls 10 on the mounting seat 6 abut against the surface of the shaft workpiece. After adjusting each support module, a stable radial support can be formed for the shaft workpiece.

[0016] The radial support frame structure of this slender shaft automatic machining equipment is fixedly installed at the corresponding machining equipment via a fixed base 1. Subsequently, the corresponding support modules are installed at the predetermined adjustment modules as needed to meet the support requirements of the support frame structure for different positions of the shaft workpiece under various conditions. The ball bearings 10 of the support module are adjusted to abut against the surface of the shaft workpiece through the adjustment module. During the relative movement between the support frame structure and the shaft workpiece, the ball bearings 10 are in direct contact with the shaft workpiece, which can effectively reduce the friction between the shaft workpiece and the support frame structure. While meeting the radial support requirements for the shaft workpiece, it makes the relative movement between the support frame structure and the shaft workpiece more stable and smooth, reducing the possibility of surface damage to the shaft workpiece.
