[0002] In modern machining, horizontal milling and boring machines are widely used as important processing equipment in the machining of various metal parts. Among them, the feed speed control device, as a crucial component of horizontal milling and boring machines, has a vital impact on processing efficiency and quality.

[0003] However, traditional horizontal milling and boring machines often have many problems, which limit their application range and machining flexibility.

[0004] The most significant issue is the feeding problem. During the machining process of parts on a boring machine, the material and the size of the hole to be machined vary. Therefore, the fixed feeding speed in actual use makes it impossible for the device to adjust the feeding speed according to the material and the size of the hole to be machined. This may cause the boring machine to have to use a fixed, non-optimal feed speed during the machining process, thus affecting the machining efficiency.

[0005] In view of this, a feed speed control device for a horizontal milling and boring machine is provided to overcome the above-mentioned defects. Utility Model Content

A secondary plate is fixedly installed on one side of the base plate, and a partition plate is installed between the base plate and the secondary plate. A rotating disk is rotatably installed on the side wall of the partition plate. A limit groove is formed inside the rotating disk, and a transmission guide rail is slidably arranged in the limit groove. A rotatable drive gear is installed on one side of the rotating disk, and a fixed guide rail is formed through the outer wall of the drive gear. A drive rod is fixedly installed on one side of the transmission guide rail, and the drive rod is located inside the fixed guide rail.

[0008] Furthermore, the specific number of the transmission guide rails is five, and the edges of the five transmission guide rails initially touch each other and are circular in shape.

[0009] Furthermore, a rotatable second screw is installed inside the sub-plate, and a moving block is threadedly connected to the outer wall of the second screw. A drive motor is fixedly installed at the top of the moving block, and a pulley is driven to one end of the drive motor. A drive belt is simultaneously fitted on the outer wall of the pulley and the five drive rails.

[0010] Furthermore, a first screw is fixedly connected to one end of the rotating disk, and the movable base is threadedly connected to the outer wall of the first screw.

[0011] Furthermore, a rotatable drive gear is installed on the outer wall of the rotating disk, and the drive gear meshes with the drive gear disk.

[0012] Furthermore, a ratchet is fixedly connected to one end of the drive gear, and the rotating disk is mounted with a fixed mounting plate and a rotatable pawl. A return spring is fixedly connected between the pawl and the mounting plate.

[0013] Furthermore, the ratchet is adapted to the pawl, and a first knob is fixedly installed on the outer wall of the ratchet on the side away from the rotating disk.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting multiple transmission guides with adjustable spacing and pulleys of fixed diameter, and simultaneously mounting transmission belts on the outer walls of both, the transmission ratio between the multiple transmission guides and the pulleys can be changed by adjusting the diameter of the circle formed by the multiple transmission guides.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] See Figure 1-5 A feeding speed regulating device for a horizontal milling and boring machine includes a base plate 1, a boring tool body 2, and a movable base 3. A secondary plate 5 is fixedly installed on one side of the base plate 1. A partition plate is installed between the base plate 1 and the secondary plate 5. A rotating disk 9 is rotatably installed on the side wall of the partition plate. A limit groove is opened inside the rotating disk 9. A transmission guide rail 10 is slidably arranged in the limit groove. A rotatable drive gear 12 is installed on one side of the rotating disk 9. A fixed guide rail 13 is opened through the outer wall of the drive gear 12. A drive rod 14 is fixedly installed on one side of the transmission guide rail 10. The drive rod 14 is located inside the fixed guide rail 13.

[0025] Furthermore, the specific number of transmission guide rails 10 is five. The edges of the five transmission guide rails 10 initially touch each other and are circular in shape. By setting five transmission guide rails 10 and setting the five transmission guide rails 10 to be circular in shape while their edges touch each other, the device can complete stable transmission under the joint action of the five transmission guide rails 10.

[0026] Furthermore, a rotatable second screw 21 is installed inside the sub-plate 5. A moving block is threaded onto the outer wall of the second screw 21. A drive motor 6 is fixedly installed at the top of the moving block. One end of the drive motor 6 is connected to a pulley 7. A drive belt 8 is simultaneously fitted onto the outer wall of the pulley 7 and the five drive rails 10.

[0027] By setting the moving block and the second screw 21 to cooperate with each other, the drive motor 6 can drive the pulley 7 to move, so that the transmission belt 8 sleeved on the outer wall of the transmission guide rail 10 and the pulley 7 can remain taut even after the spacing of the transmission guide rail 10 is adjusted. A second knob 20 is fixedly connected to one side of the second screw 21.

[0028] It should be noted that one end of the rotating disk 9 is fixedly connected to the first screw 4, and the movable base 3 is threadedly connected to the outer wall of the first screw 4.

[0029] In addition, a rotatable drive gear 11 is installed on the outer wall of the rotating disk 9. The drive gear 11 meshes with the drive gear disk 12. A ratchet 15 is fixedly connected to one end of the drive gear 11. The rotating disk 9 is equipped with a fixed mounting plate 17 and a rotatable pawl 16. A return spring 18 is fixedly connected between the pawl 16 and the mounting plate 17.

[0030] By setting the drive gear 11 to mesh with the drive gear disk 12, and a ratchet 15 fixedly connected to one end of the drive gear 11, the ratchet 15 and the pawl 16 are adapted to each other, so that the drive gear 11 can be limited by the pawl 16 after rotation, and cannot easily reverse.

[0031] It should also be noted that a first knob 19 is fixedly installed on the outer wall of the ratchet 15 on the side away from the rotating disk 9.

[0032] In practical implementation, when the feeding speed of the moving base 3 needs to be adjusted, the user can directly rotate the first knob 19, causing the first knob 19 to drive the base plate 1 to rotate. The drive gear 11 meshes with the drive gear 12, so the drive gear 12 will also rotate synchronously. The rotating disk 9 has a limiting groove inside. While the transmission guide rail 10 is in the limiting groove, the drive rod 14 fixedly installed on its outer wall is also in the fixed guide rail 13 on the outer wall of the drive gear 12. Therefore, under the combined action of the limiting groove and the fixed guide rail 13 in the rotating state, the transmission guide rail 10 will expand outward along the trajectory of the limiting groove, thereby increasing the diameter of the circle formed by multiple transmission guide rails 10, changing the transmission ratio between multiple transmission guide rails 10 and the pulley 7, thereby realizing the adjustment of the rotation speed of the first screw 4, so that the feeding speed of the moving base 3 can be adjusted, and the device can be applied to different materials and different processing requirements.

[0033] By setting multiple transmission guide rails 10 with adjustable spacing and pulleys 7 with fixed diameter, and simultaneously sleeved with transmission belts 8 on the outer walls of both, the transmission ratio between the multiple transmission guide rails 10 and the pulleys 7 can be changed by adjusting the diameter of the circle formed by the multiple transmission guide rails 10, thereby realizing the feeding speed of the moving base 3, increasing the applicability of the device and improving its practicality.

[0034] Working principle: When the feeding speed of the moving base 3 needs to be adjusted, the user can directly rotate the first knob 19, causing the first knob 19 to drive the base plate 1 to rotate. The drive gear 11 meshes with the drive gear 12, so the drive gear 12 will also rotate synchronously. The rotating disk 9 has a limit groove inside. While the transmission guide rail 10 is in the limit groove, the drive rod 14 fixedly installed on its outer wall is also in the fixed guide rail 13 on the outer wall of the drive gear 12. Therefore, under the combined action of the limit groove and the fixed guide rail 13 in the rotating state, the transmission guide rail 10 will expand outward along the trajectory of the limit groove, thereby increasing the diameter of the circle formed by multiple transmission guide rails 10, changing the transmission ratio between multiple transmission guide rails 10 and the pulley 7, thereby realizing the adjustment of the rotation speed of the first screw 4, so that the feeding speed of the moving base 3 can be adjusted, and the device can be applied to different materials and different processing requirements.

[0035] By setting multiple transmission guide rails 10 with adjustable spacing and pulleys 7 with fixed diameter, and simultaneously sleeved with transmission belts 8 on the outer walls of both, the transmission ratio between the multiple transmission guide rails 10 and the pulleys 7 can be changed by adjusting the diameter of the circle formed by the multiple transmission guide rails 10, thereby realizing the feeding speed of the moving base 3, increasing the applicability of the device and improving its practicality.
