Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a left and right milling assembly for a round bar drilling, tapping and milling machine. Background Technology

[0002] In the field of machining, the processing steps are very extensive. Due to the different structures of various parts, the required equipment varies. Currently, two types of equipment are typically used for processing: ordinary machine tools combined with specific tooling fixtures, and specially designed machines. Ordinary machine tools have the characteristics of low investment but low processing efficiency; while special-purpose machines generally have higher investment and longer design cycles, but higher processing efficiency. Furthermore, in the machining of round bars, for the milling process, existing equipment often suffers from insufficient precision, low efficiency, and unstable clamping of the round bars, easily causing clamping damage or processing deviations, making it difficult to meet the requirements of efficient and precise machining. Utility Model Content

[0003] The purpose of this invention is to provide a left and right milling assembly for a round bar drilling, tapping and milling machine, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a left and right milling assembly for a round bar drilling, tapping, and milling machine, comprising a mounting base plate, guide rails, and a position adjustment plate. Guide rails and a position adjustment plate are respectively mounted on both sides of the top of the mounting base plate. A servo motor mounting plate is fixed to the side of the mounting base plate, and a feed servo motor is mounted on the servo motor mounting plate. A slider plate is slidably connected to the guide rails. The output end of the feed servo motor passes through the servo motor mounting plate and is fixedly connected to one end of a lead screw. The lead screw is fixed to the bottom of the slider plate. The nut is threadedly connected. A spindle mounting base is installed on the top of the slider plate. A spindle body is fixed on the top of the spindle mounting base. A sprocket drive box is installed at one end of the spindle body. A spindle motor is installed on one side of the top of the sprocket drive box. A milling cutter is provided at the other end of the spindle body. The milling cutter is fixedly connected to the spindle inside the spindle body. A positioning cylinder is also installed on the spindle mounting base. A clamp mounting base is fixed on the position adjustment plate. A hydraulic cylinder and a hydraulic clamp assembly are respectively installed on both sides of the top of the clamp mounting base.

[0005] The feed servo motor drives the lead screw to rotate, which in turn drives the sliding block to move back and forth, thereby moving the main spindle body back and forth. The spindle motor rotates through a sprocket transmission box, driving the spindle inside the main spindle body to rotate, which in turn drives the milling cutter to rotate. A hydraulic clamp holds the round bar, and a positioning cylinder initially controls the length positioning of the round bar. Utilizing a high-strength mechanical spindle body and advanced milling cutters, it enables fast and precise machining, improving production efficiency.

[0006] Preferably, the output end of the spindle motor meshes with the sprocket inside the sprocket drive box, and the sprocket inside the sprocket drive box meshes with the spindle inside the spindle body. The output end of the spindle motor rotates to drive the sprocket inside the sprocket drive box, and the sprocket group rotates in sequence to drive the spindle inside the spindle body to rotate, thereby driving the milling cutter to rotate.

[0007] Preferably, the surface of the mounting base plate is provided with an adjustment groove, and the position adjustment plate is connected to the adjustment groove by bolts. When it is necessary to process round bars of different lengths, the bolts are loosened, the position adjustment plate is moved along the adjustment groove to a suitable position, and then the bolts are tightened to fix the position adjustment plate, so as to adapt to the processing requirements of round bars of different lengths.

[0008] Preferably, the hydraulic clamp assembly includes a fixed clamping plate, an anti-slip pad, and a movable clamping plate. The fixed clamping plate is fixedly installed on the clamping mounting base, and the movable clamping plate is slidably connected to the fixed clamping plate. Anti-slip pads are provided on the opposite sides of the fixed clamping plate and the movable clamping plate.

[0009] Preferably, one side of the movable clamp is fixedly connected to the output end of the hydraulic cylinder.

[0010] Preferably, the milling cutter is correspondingly arranged with the hydraulic clamp assembly.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes a feed servo motor to drive a lead screw, which in turn drives a slider plate to move back and forth along a guide rail. This, in turn, moves the main spindle body back and forth, allowing for the adjustment of the milling cutter's feed. The main spindle motor, via a sprocket transmission box, drives the spindle within the main spindle body to rotate, which in turn drives the milling cutter to perform milling. This design offers convenient control, enabling fast and precise machining and improving production efficiency. A hydraulic clamping assembly is used to clamp the round bar. A hydraulic cylinder drives a moving clamping plate to cooperate with a fixed clamping plate to clamp the round bar. Anti-slip pads are provided on opposite sides of both the fixed and moving clamping plates to increase friction, making clamping more stable and preventing damage to the round bar. A positioning cylinder provides initial control of the round bar's length positioning, ensuring consistency and accuracy in the round bar machining process. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Please see Figure 1-3 This utility model provides a left and right milling assembly for a round bar drilling, tapping, and milling machine, including a mounting base plate 1, guide rails 4, and a position adjustment plate 15. Guide rails 4 and position adjustment plates 15 are respectively mounted on both sides of the top of the mounting base plate 1. A servo motor mounting plate 3 is fixed to the side of the mounting base plate 1, and a feed servo motor 2 is mounted on the servo motor mounting plate 3. A slider plate 6 is slidably connected to the guide rails 4. The output end of the feed servo motor 2 passes through the servo motor mounting plate 3 and is fixedly connected to one end of a lead screw 5. The lead screw 5 is threadedly connected to a nut fixed to the bottom of the slider plate 6. A spindle mounting base 7 is installed on the top of the spindle mounting base 7, and a spindle body 10 is fixed on the top of the spindle mounting base 7. A sprocket drive box 9 is installed at one end of the spindle body 10, and a spindle motor 8 is installed on one side of the top of the sprocket drive box 9. A milling cutter 12 is provided at the other end of the spindle body 10, and the milling cutter 12 is fixedly connected to the spindle inside the spindle body 10. A positioning cylinder 11 is also installed on the spindle mounting base 7, and a clamp mounting base 14 is fixed on the position adjustment plate 15. A hydraulic cylinder 13 and a hydraulic clamp assembly 16 are respectively installed on both sides of the top of the clamp mounting base 14.

[0019] The output end of the main spindle motor 8 engages with the sprocket inside the sprocket transmission box 9 for transmission, and the sprocket inside the sprocket transmission box 9 engages with the main spindle inside the main spindle body 10 for transmission.

[0020] Specifically, the output of the spindle motor 8 rotates to drive the sprocket inside the sprocket transmission box 9. The sprocket set rotates in sequence, driving the spindle inside the spindle body 10 to rotate, thereby driving the milling cutter 12 to rotate.

[0021] An adjustment groove is provided on the surface of the mounting base plate 1, and the position adjustment plate 15 is connected to the adjustment groove by bolts.

[0022] Specifically, when it is necessary to process round bars of different lengths, loosen the bolts, move the position adjustment plate 15 along the adjustment groove to the appropriate position, and then tighten the bolts to fix the position adjustment plate 15 to adapt to the processing requirements of round bars of different lengths.

[0023] The hydraulic clamp assembly 16 includes a fixed clamping plate 161, an anti-slip pad 162, and a movable clamping plate 163. The fixed clamping plate 161 is fixedly installed on the clamping mounting base 14, and the movable clamping plate 163 is slidably connected to the fixed clamping plate 161. Anti-slip pads 162 are provided on the opposite side of the fixed clamping plate 161 and the movable clamping plate 163.

[0024] Specifically, the anti-slip pad 162 can increase the friction between the pad and the round bar, preventing the round bar from sliding during processing, and at the same time avoiding the clamping plate from causing damage to the surface of the round bar.

[0025] One side of the movable clamp 163 is fixedly connected to the output end of the hydraulic cylinder 13.

[0026] Specifically, when the hydraulic cylinder 13 is working, its output end extends and retracts, causing the movable clamping plate 163 to slide along the fixed clamping plate 161, thereby achieving the clamping and releasing action of the round bar.

[0027] The milling cutter 12 is set to correspond with the hydraulic fixture assembly 16.

[0028] Specifically, this ensures that the milling cutter 12 can accurately align with the end face of the round bar to be machined, which is clamped by the hydraulic fixture assembly 16, thus guaranteeing the accuracy of the milling process.

[0029] Working principle: When using this left and right milling assembly, firstly, the position of the position adjustment plate 15 on the mounting base plate 1 is adjusted according to the length of the round bar to be processed, and then fixed with bolts. Next, the round bar is placed between the fixed clamping plate 161 and the movable clamping plate 163 of the hydraulic clamping assembly 16, and the positioning cylinder 11 is activated to initially position the length of the round bar. Then, the hydraulic cylinder 13 operates, pushing the movable clamping plate 163 towards the fixed clamping plate 161, which, in conjunction with the fixed clamping plate 161, clamps the round bar. The anti-slip pad 162 serves to prevent slipping and pinching. Afterwards, the spindle motor 8 starts, and its output rotates, driving the sprocket drive inside the sprocket transmission box 9. The sprocket assembly then drives the spindle inside the spindle body 10 to rotate, and the spindle rotation drives the milling cutter 12 to rotate. Simultaneously, the feed servo motor 2 starts, and its output end drives the lead screw 5 to rotate. The lead screw 5 engages with the nut at the bottom of the slider plate 6, driving the slider plate 6 to slide along the guide rail 4, thereby moving the spindle mounting base 7 and the spindle body 10. This causes the rotating milling cutter 12 to feed towards the end face of the round bar for milling. After the machining is completed, the feed servo motor 2 reverses, driving the milling cutter 12 to retract. The spindle motor 8 stops working, the hydraulic cylinder 13 drives the moving clamp 163 to reset and release the round bar, and the positioning cylinder 11 resets, completing one milling machining operation.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
