Description

Technical Field

[0001] This utility model relates to the field of ball screw blank processing technology, and in particular to a ball screw blank cutting machine with automatic feeding function. Background Technology

[0002] A lead screw is a mechanical transmission element whose main function is to convert rotary motion into linear motion, or vice versa. It can also transmit torque and axial force. Its core function is to achieve the conversion of motion form through the thread structure, and it is widely used in industrial scenarios that require precise control and high transmission efficiency.

[0003] The working principle of a lead screw blank cutting machine with automatic feeding function: The blank is transported to the feed port in an orderly manner by a conveyor belt. The conveying mechanism may use rollers, chains or pneumatic pushers to ensure that the blank enters the cutting area at a set rhythm. After the blank is positioned, the clamp automatically clamps it. The cutting machine cuts the lead screw blank. The cut lead screw blank is sent out by the conveyor belt. The dimensional accuracy is checked by a vision system or manually.

[0004] Screw blank cutting machines with automatic feeding functions generate metal chips during the cutting process. These metal chips are prone to accumulating on the cutting platform if not treated. Excessive accumulation will affect the cutting effect of the equipment and may also cause inconvenience to the operator, thus affecting the processing efficiency of the equipment.

[0027] Reference Figure 1-5 The first embodiment of this utility model provides a lead screw blank cutting machine with automatic feeding function, including a cutting platform 1 and two mounting seats 7 at the bottom of the cutting platform 1. An active rotating roller 16 is rotatably connected between the two mounting seats 7, and a plurality of driven rotating rollers 17 are rotatably connected between the two mounting seats 7. A servo motor for driving the active rotating roller 16 to rotate is fixedly installed on the outer surface of the mounting seat 7. A conveyor belt 12 is sleeved on the outer wall of the active rotating roller 16, and a metal mesh conveyor belt 13 is sleeved on the outer wall of the active rotating roller 16. A scraper 14 is fixedly connected between the two mounting seats 7.

[0028] A collection box 15 is slidably connected between two mounting bases 7. Two support plates 2 are fixedly installed on the top of the cutting platform 1. An adjusting plate 9 is slidably connected between the two support plates 2. A groove is opened on the outer surface of the adjusting plate 9. A connecting plate 11 is slidably connected to the inner wall of the groove. A cutting machine 10 is fixedly connected to the side of the connecting plate 11 away from the groove. A top plate 3 is fixedly connected to the top of the two support plates 2. A telescopic cylinder is fixedly connected to the top of the top plate 3. A moving plate 4 is fixedly connected to the output end of the telescopic cylinder. A guide seat is fixedly connected to the top of the top plate 3. A guide rod is slidably connected to the inner wall of the guide seat. The end of the guide rod away from the guide seat is fixedly connected to the top of the moving plate 4.

[0029] Example 2

[0030] Reference Figure 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the bottom of the movable plate 4 is fixedly connected to the top of the adjusting plate 9, a scale 8 is fixedly connected to the outer surface of the movable plate 4, a second sliding groove is opened on the outer surface of the adjusting plate 9, a threaded rod 18 is slidably connected to the inner wall of the second sliding groove, the outer wall of the threaded rod 18 is slidably connected to the inner wall of the connecting plate 11, a locking ring 19 is threadedly connected to the outer wall of the threaded rod 18, a square groove is opened through the top of the cutting platform 1, and a fixed seat is fixedly connected to the top of the cutting platform 1.

[0031] An electric telescopic rod 6 is fixedly connected to the outer wall of the fixed base. An arc-shaped clamping member 5 is fixedly connected to the side of the electric telescopic rod 6 away from the fixed base. A rubber layer is fixedly connected to the side of the arc-shaped clamping member 5 away from the electric telescopic rod 6. A long groove is opened through the outer surface of the support plate 2. A sliding groove 3 is slidably connected to the inner wall of the long groove. A slider 20 is slidably connected to the inner wall of the sliding groove 3. A connecting block 21 is fixedly connected to the side of the slider 20 away from the sliding groove 3. The side of the connecting block 21 away from the slider 20 is fixedly connected to the side of the moving plate 4 close to the support plate 2.

[0032] The remaining structure is the same as that in Example 1.

[0033] During operation, the operator first starts the servo motor to drive the active rotating roller 16 to rotate, which in turn drives the conveyor belt 12 and the metal mesh conveyor belt 13 to start working. The lead screw blank to be cut is placed on the conveyor belt 12, which can transport the lead screw blank to be cut to the two sets of arc-shaped clamping parts 5. Then, the electric telescopic rod 6 is started. The two sets of electric telescopic rods 6 are synchronously controlled and fed back to a unified pressure sensor to achieve synchronous control. This pushes the two sets of arc-shaped clamping parts 5 to move in opposite directions along the square groove to clamp and fix the lead screw blank to be cut. The rubber layer on the inner wall of the arc-shaped clamping part 5 is adapted to lead screw blanks of different diameters. Then, the telescopic cylinder on the top plate 3 is started to drive the moving plate 4 to move, which in turn drives the adjusting plate 9 to move. According to the required length of the lead screw blank to be cut, it is pulled to slide on the inner wall of the second slide groove of the threaded rod 18, thereby driving the connecting plate 11 to move to adjust the position of the cutting machine 10.

[0034] During use, after the position of the cutting machine 10 is adjusted, the threaded rod 18 is rotated with the corresponding tool to fix the position of the cutting machine 10 in conjunction with the locking ring 19. Then the cutting machine 10 starts to work and cuts the lead screw blank. The metal chips generated by cutting fall onto the metal mesh conveyor belt 13 below through the square groove. The metal mesh conveyor belt 13 transports the metal chips. The scraper 14 fixedly connected between the two mounting seats 7 scrapes the metal chips off the metal mesh conveyor belt 13. The scraped metal chips fall into the collection box 15 below and are collected and processed by the staff. After the cutting operation is completed, the conveyor belt 12 transports the lead screw blank to the next stage for processing.
