Description

Technical Field

[0001] This utility model relates to the field of horizontal milling and boring machine technology, specifically a horizontal milling and boring machine that is easy to clamp and position. Background Technology

[0002] Milling and boring machines are widely used machining tools in the manufacturing industry, combining the functions of boring and milling machines into one, resulting in higher processing efficiency and better precision, thereby greatly improving product quality and operator productivity. Milling and boring machines combine the machining methods of boring and milling machines, primarily used for boring holes and milling planes. They are classified by automation level into: traditional milling and boring machines, precision milling and boring machines, and CNC milling and boring machines; and by layout into: vertical milling and boring machines, horizontal milling and boring machines, and floor-type milling and boring machines.

[0003] A Chinese patent (publication number CN220680085U) discloses a horizontal milling and boring machine that is easy to clamp and position. By setting up a placement plate, a fixing block, an electric telescopic rod, and a clamping block, the electric telescopic rod is activated, and the telescopic effect of the electric telescopic rod causes the clamping blocks around it to move inward simultaneously, thereby achieving the function of clamping the object.

[0004] However, in actual use, the horizontal milling and boring machine designed above, which is convenient for clamping and positioning, achieves workpiece positioning and clamping by synchronously extending and retracting the electric telescopic rods around the perimeter towards the center. However, in actual operation, multiple electric telescopic rods may not be able to extend and retract completely synchronously. Due to factors such as signal transmission, time differences may occur, resulting in uneven workpiece clamping, or even damage to the workpiece. Utility Model Content

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: it includes a milling and boring machine body 18 and a movable table 1 set on the top of the milling and boring machine body 18. A connecting rod 5 is fixedly set on the top of the movable table 1, and a mounting part 6 is fixedly installed on the top of the connecting rod 5. A drive gear 8 is rotatably installed on one end of the mounting part 6, and a rotary motor 7 is fixedly installed on the bottom of the mounting part 6. The drive end of the rotary motor 7 is fixedly connected to the drive gear 8. A driven gear 9 is rotatably connected to the top of the mounting part 6. The driven gear 9 and the drive gear 8 are meshed. An arc-shaped groove 12 is opened on the driven gear 9, and a round rod 13 is slidably inserted into the arc-shaped groove 12. A slot is opened on one side of the mounting part 6, and a plug rod 11 is slidably inserted into the slot. The round rod 13 is fixedly installed on the end of the plug rod 11 near the driven gear 9. Multiple clamping plates 14 are provided, and the multiple clamping plates 14 are arranged in a circumferential array on the outside of the driven gear 9. A protrusion is connected to one side of the mounting part 6, and the drive gear 8 is rotatably installed on the top of the protrusion.

[0022] In practice, the rotating motor 7 can be started to drive the driving gear 8 to rotate. When the driving gear 8 rotates, it drives the driven gear 9, which meshes with the driving gear 8, to rotate on the top of the mounting part 6. The driven gear 9 rotates around the cylinder 19. When the driven gear 9 rotates, the arc groove 12 on the driven gear 9 drives the round rod 13 to move, so that the round rod 13 slides synchronously inside the mounting part 6. When the round rod 13 moves, it drives the insertion rod 11 to slide. Multiple insertion rods 11 move synchronously. The number of clamping plates 14 matches the number of insertion rods 11. When the clamping plates 14 move with the insertion rods 11, multiple clamping plates 14 move synchronously toward the support plate 10, thereby realizing the clamping and positioning of the workpiece on the support plate 10, which facilitates the subsequent processing of the workpiece.

[0023] See Figure 2A clamping plate 14 is fixedly connected to the end of the insertion rod 11 away from the driven gear 9. A buffer spring 17 is fixedly connected to the side of the clamping plate 14 near the driven gear 9. A buffer plate 15 is fixedly connected to the other end of the buffer spring 17. A telescopic member 16 is fixedly connected to the end of the clamping plate 14 near the driven gear 9. The telescopic end of the telescopic member 16 is fixedly connected to the buffer plate 15.

[0024] When the clamping plate 14 approaches the workpiece and clamps the workpiece, the buffer plate 15 on one side of the clamping plate 14 contacts the workpiece first. When the buffer plate 15 contacts the workpiece, the buffer spring 17 deforms and is compressed, and the telescopic member 16 contracts synchronously to buffer the impact force when the buffer plate 15 approaches the support plate 10, so as to avoid damage to the workpiece.

[0025] See Figure 1 The movable stage 1 is internally connected to a screw 2, and a drive motor 3 is fixedly installed on the outside of the movable stage 1. The drive end of the drive motor 3 is fixedly connected to the screw 2. The bottom of the connecting rod 5 is fixedly connected to a base 4, which is threaded onto the outside of the screw 2. A guide rod is fixedly installed on one side of the screw 2 and inserted into the inside of the base 4.

[0026] By setting screw 2, when the drive motor 3 starts, the base 4 can slide along the guide rod inside the moving table 1, realizing the movement effect of clamping the workpiece on the top of the support plate 10. Setting the guide rod helps to improve the stability of the sliding of the base 4. The guide rod is set inside the moving table 1 and is set parallel to screw 2.

[0027] See Figure 4 A cylinder 19 is fixedly installed at the center of the mounting component 6, and the driven gear 9 is movably sleeved on the outside of the cylinder 19.

[0028] By setting the cylinder 19, the driven gear 9 can rotate around the cylinder 19 on the top of the mounting part 6, driving the rod 13 to slide.

[0029] See Figure 2 and Figure 3 A support plate 10 is fixedly connected to the top of the cylinder 19, and the support plate 10 is located above the cylindrical rod 13.

[0030] By placing the support plate 10 above the round rod 13, the sliding of the round rod 13 is not affected. A limit plate is provided at the top of the round rod 13. The outer diameter of the limit plate is larger than the inner diameter of the round rod 13, which limits the sliding of the round rod 13 in the arc groove 12.

[0031] Working principle: When the device is in use, the rotating motor 7 is started to drive the drive gear 8 to rotate. When the drive gear 8 rotates, it drives the driven gear 9, which meshes with the drive gear 8, to rotate on the top of the mounting part 6. The driven gear 9 rotates around the cylinder 19. When the driven gear 9 rotates, the arc groove 12 on the driven gear 9 drives the round rod 13 to move, so that the round rod 13 slides synchronously inside the mounting part 6. When the round rod 13 moves, it drives the insertion rod 11 to slide. Multiple insertion rods 11 move synchronously. The number of clamping plates 14 matches the number of insertion rods 11. When the clamping plates 14 move with the insertion rods 11, multiple clamping plates 14 move synchronously toward the support plate 10, thereby realizing the clamping and positioning of the workpiece on the support plate 10, which facilitates the subsequent processing of the workpiece.

[0032] When the clamping plate 14 approaches the workpiece and clamps the workpiece, the buffer plate 15 on one side of the clamping plate 14 contacts the workpiece first. When the buffer plate 15 contacts the workpiece, the buffer spring 17 deforms and is compressed, and the telescopic member 16 contracts synchronously to buffer the impact force when the buffer plate 15 approaches the support plate 10, so as to avoid damage to the workpiece.
