Abstract
Description
Technical Field
[0001] This utility model relates to the field of chip removal in machine tools, and in particular to a double-helix high-efficiency chip removal mechanism for vertical machine tools. Background Technology
[0002] In order for vertical machine tools to operate normally, chip removal is required. Therefore, vertical machine tools adopt a single spiral or scraper chip removal structure to ensure normal operation.
[0003] Chinese Patent Application No. CN202222248871.8 discloses a double-spiral chip conveyor for a vertical machine tool. This design, through an inclined material collection trough, allows waste material pushed to the trough by the chip conveyor body to move along the inclined surface. Combined with the side grooves on the side wall of the material collection trough and the side channels connected to the side grooves, a slot is provided to discharge the waste material from the side wall of the material collection trough. Since the waste material has a downward sliding tendency on the inclined surface, it is constantly agitated by the spiral shaft of the chip conveyor body, causing the waste material to slide out from the side grooves along the side channels, achieving the function of discharging material from the side. This allows the chip conveyor body to discharge material without tilting.
[0004] Existing chip removal mechanisms for vertical machine tools have certain drawbacks. First, most chip removal mechanisms use a spiral chip removal method, but this method has problems such as low chip removal efficiency, long chip entanglement, and easy clogging. Especially when machining cast iron or aluminum alloys, chips tend to accumulate, causing the machine tool to stop for cleaning and affecting the continuity of processing. To address this, we propose a double spiral high-efficiency chip removal mechanism for vertical machine tools. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a double-helix high-efficiency chip conveying mechanism for vertical machine tools. By setting a guide frame and anti-clogging plugs, when the chip conveying mechanism becomes clogged during chip conveying, the starting motor can move the moving block in the opposite direction. The moving block drives the receiving frame and the guide frame, which in turn drives multiple anti-clogging plugs to contact the threaded blades. At the same time as contact, the sliding rod and the reset ring generate force to drive the guide frame and the anti-clogging plugs. The adjustable guide frame and anti-clogging plugs are set on the outside of the threaded blades, and the front end of the anti-clogging plug is equipped with a rubber protective ring to prevent damage to the threaded blades. It can effectively clean the surface of the threaded blades and the chips and debris in the collection groove, thereby clearing the blocked parts and avoiding the decrease in chip conveying efficiency or equipment failure due to blockage. This mechanism is different from traditional spiral chip conveyors that are prone to blockage due to chip accumulation or overload, and maintains the smooth operation of the system.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A double-helix high-efficiency chip conveying mechanism for a vertical machine tool includes a helical chip conveyor body. A movable block is slidably connected inside the helical chip conveyor body. A receiving frame is fixedly connected to the outer end of the movable block. A symmetrically distributed slide rod is slidably connected to the inner end of the receiving frame. A guide frame is slidably connected to the outer end of the slide rod. A plurality of anti-clogging plugs are fixedly connected to the front end of the guide frame. A reset ring is sleeved on the outer end of the slide rod.
[0008] By installing a guide rack and an anti-clogging plug, this mechanism can avoid the problem of clogging caused by chip accumulation or overload in traditional spiral chip conveyors, thus ensuring smooth system operation.
[0009] Furthermore, both ends of the slide rod are fixedly connected to limit heads.
[0010] By installing a limiting head, a connecting limiting structure can be formed at both ends of the slide rod. When the guide frame moves, the limiting head can ensure that the connection between the moving guide frame and the receiving frame will not fall off.
[0011] Furthermore, a second motor is fixedly connected to the outer end of the spiral chip conveyor body, a rotating shaft is installed on the transmission end of the second motor, and a parapet wheel assembly is installed on the outer end of the rotating shaft.
[0012] The ease of operation of this mechanism can be improved by installing the parachute wheel assembly.
[0013] Furthermore, a screw is fixedly connected to the inner end of the parachute assembly on the side away from the rotating shaft, and the screw is threadedly connected to the moving block.
[0014] The operation efficiency of this double-helix high-efficiency chip removal mechanism can be further improved by installing a screw and a moving block.
[0015] Furthermore, a guide block is fixedly connected to the rear end of the movable block, and a guide rod is slidably connected to the inner end of the guide block.
[0016] By installing guide rods, the operational stability of this double-helix high-efficiency chip removal mechanism can be further improved.
[0017] Furthermore, mounting seats are fixedly connected to both ends of the guide rod, and the mounting seats are located at the inner end of the spiral chip conveyor body.
[0018] By setting a mounting base, a support structure can be formed on the outside of the guide rod, allowing the guide rod to operate stably.
[0019] Furthermore, a pair of guide plates are fixedly connected to both ends of the spiral chip conveyor body, and a pair of motors are fixedly connected to the front end of the spiral chip conveyor body. A connecting shaft is fixedly connected to the transmission end of the motor, and a threaded blade is fixedly connected to the outer end of the connecting shaft.
[0020] By installing a connecting shaft and threaded blades, the practicality of this double-helix high-efficiency chip removal mechanism for use in vertical machine tools can be improved.
[0021] Furthermore, the top end of the spiral chip conveyor body is threaded with multiple connecting brackets, and both ends of the spiral chip conveyor body have inclined material collection troughs that extend towards the inner end of the spiral chip conveyor body. The side walls of the material collection troughs are provided with side grooves.
[0022] By setting up a material collection trough, the efficiency of the chip removal operation of this double-helix high-efficiency chip removal mechanism can be further improved.
[0023] In summary, this utility model has the following beneficial effects:
[0024] By setting up a guide frame and anti-clogging plugs, when the chip conveying mechanism becomes clogged during chip conveying, the starting motor can move the moving block in the opposite direction. The moving block then drives the receiving frame and the guide frame, which in turn drives multiple anti-clogging plugs to contact the threaded blades. At the same time, the sliding rod and the reset ring generate force to drive the guide frame and the anti-clogging plugs. The adjustable guide frame and anti-clogging plugs are set on the outside of the threaded blades, and the front end of the anti-clogging plug is equipped with a rubber protective ring, which will not damage the threaded blades. It can effectively clean the chip debris on the surface of the threaded blades and in the collection groove, thereby clearing the blocked parts and avoiding the decrease in chip conveying efficiency or equipment failure due to blockage. This mechanism is different from the traditional spiral chip conveyor, which is prone to blockage due to chip accumulation or overload, and keeps the system running smoothly.
[0025] By setting a screw and a moving block, the rotating screw can interact with the external moving block through a threaded action, thereby enabling the moving block to move and drive the connected receiving frame and guide frame. This allows the guide frame and anti-clogging plug to move to the blockage point for convenient material discharge and unblocking, further improving the operating effect of the double-helix high-efficiency chip removal mechanism.
[0026] By setting connecting shafts and threaded blades, two pairs of connecting shafts and threaded blades are symmetrically located at the inner end of the spiral chip conveyor body. Once a pair of motors are started, they drive the connecting shafts and threaded blades to rotate. At this time, through the inner and outer double spiral reverse rotation design, combined with the flow guiding and diversion structure, the classification, conveying and rapid discharge of light and heavy chips are realized, which improves the practicality of this double spiral high-efficiency chip conveying mechanism for vertical machine tools.

[0035] Reference Figure 1-5 As shown, a preferred embodiment of the present invention is a double-helix high-efficiency chip removal mechanism for a vertical machine tool, including a helical chip conveyor body 1. A movable block 13 is slidably connected inside the helical chip conveyor body 1. A receiving frame 16 is fixedly connected to the outer end of the movable block 13. A symmetrically distributed slide rod 17 is slidably connected to the inner end of the receiving frame 16. A guide frame 18 is slidably connected to the outer end of the slide rod 17. A plurality of anti-clogging plugs 19 are fixedly connected to the front end of the guide frame 18. A reset ring 20 is sleeved on the outer end of the slide rod 17.
[0036] Reference Figure 2 and Figure 3 As shown, both ends of the slide bar 17 are fixedly connected to limit heads 21.
[0037] Reference Figure 1 , Figure 2 and Figure 4 As shown, a second motor 9 is fixedly connected to the outer end of the spiral chip conveyor body 1. A rotating shaft 10 is installed on the transmission end of the second motor 9, and a parapet wheel assembly 11 is installed on the outer end of the rotating shaft 10.
[0038] Reference Figure 2 and Figure 5 As shown, a screw 12 is fixedly connected to the inner end of the parachute assembly 11 on the side away from the rotating shaft 10, and the screw 12 is threadedly connected to the moving block 13.
[0039] Reference Figure 5 As shown, a guide block 14 is fixedly connected to the rear end of the movable block 13, and a guide rod 15 is slidably connected to the inner end of the guide block 14.
[0040] Reference Figure 2 As shown, the guide rod 15 is fixedly connected to the two ends of the mounting base 22, which is located at the inner end of the spiral chip conveyor body 1.
[0041] By starting motor 29, the parasol wheel assembly 11, composed of a pair of meshing bevel gears, can rotate shaft 10 and parasol wheel assembly 11 together, making it easier for parasol wheel assembly 11 to rotate and adjust screw 12. The moving block 13 can then move in the opposite direction, driving the receiving frame 16 and guide frame 18. This allows the guide frame 18 and anti-clogging plug 19 to move to the blockage point for convenient material discharge and unblocking. The guide frame 18 then drives multiple anti-clogging plugs 19 to contact the threaded blades 5. Simultaneously, the sliding rod 17 and reset ring 20 exert force to move the guide frame 18 and anti-clogging plugs 19 together with the moving block 13. The guide block 14 can slide on the outer end of the guide rod 15, and the guide rod 15 restricts and guides the guide block 14, making the position movement of the guide block 14 and the moving block 13 more stable. The guide frame 18 will not fall off or deviate when it moves. The adjustable guide frame 18 and the anti-clogging plug 19 are set on the outside of the threaded blade 5, and the front end of the anti-clogging plug 19 is equipped with a rubber protective ring, which will not damage the threaded blade 5. It can effectively clean the surface of the threaded blade 5 and the chips and debris in the collection groove 7, thereby clearing the blocked parts and avoiding the decrease in chip removal efficiency or equipment failure due to blockage. This mechanism is different from the traditional spiral chip conveyor which is prone to blockage due to chip accumulation or overload.
[0042] Reference Figure 1 As shown, a pair of guide plates 2 are fixedly connected to both ends of the spiral chip conveyor body 1, and a pair of motors 3 are fixedly connected to the front end of the spiral chip conveyor body 1. A connecting shaft 4 is fixedly connected to the transmission end of the motors 3, and a threaded blade 5 is fixedly connected to the outer end of the connecting shaft 4.
[0043] Reference Figure 1 As shown, the top of the spiral chip conveyor body 1 is threaded with multiple connecting brackets 6, and both ends of the spiral chip conveyor body 1 have inclined material collection troughs 7 that extend into the inner end of the spiral chip conveyor body 1. The side walls of the material collection troughs 7 are provided with side grooves 8.
[0044] By installing two pairs of connecting shafts 4 and threaded blades 5 symmetrically located at the inner end of the spiral chip conveyor body 1, and starting a pair of motors 3, the connecting shafts 4 and threaded blades 5 are driven to rotate. At this time, through the inner and outer double spiral reverse rotation design, combined with the flow guiding and diversion structure, the classification, conveying and rapid discharge of light and heavy chips are realized, which improves the practicality of this double spiral high-efficiency chip conveying mechanism for vertical machine tools. The material collection trough 7 adopts a V-shaped design to ensure that the chips naturally slide down to the spiral structure, realizing rapid diversion and concentration of the discharged chips, preventing chips from accumulating on one side and causing blockage, and further improving the smooth operation of the chip conveying mechanism.
[0045] Specific implementation process: When this mechanism is in use, during the processing of a vertical machine tool, the chips fall into the collection trough 7 below the worktable. Since the collection trough 7 has a U-shaped structure, the chips automatically slide down to the inside of both sides of the spiral chip conveyor body 1. At this time, a pair of motors 3 are started. At this time, the two symmetrically distributed connecting shafts 4 and the threaded blades 5 rotate synchronously, conveying the chips to the collection boxes at both ends in two directions. At this time, through the inner and outer double spiral reverse rotation design, combined with the flow guiding and diversion structure, the classification, conveying and rapid discharge of light and heavy chips are realized.
[0046] Furthermore, when a blockage occurs during operation, motor 29 is started. After motor 29 starts, it can drive the rotating shaft 10 and the parasol wheel assembly 11 to rotate together, making it easier for the parasol wheel assembly 11 to drive the screw 12 to rotate and adjust. The rotating screw 12 can engage with the external moving block 13 through a threaded action, thereby enabling the moving block 13 to move and drive the connected receiving frame 16 and the guide frame 18. The guide frame 18 then drives multiple anti-blocking plugs 19 to contact the threaded blades 5. At the same time as contact, the slide rod 17 and the reset ring 20 generate force to drive the guide frame 18 and the anti-blocking plugs 19. The limiting head 21 can form a connection limit at both ends of the slide rod 17. With its positioning structure, when the guide frame 18 moves, the limiting head 21 ensures that the connection between the moving guide frame 18 and the receiving frame 16 will not fall off. The adjustable guide frame 18 and the anti-clogging plug 19 are located outside the threaded blade 5, and the anti-clogging plug 19 has a rubber protective ring at the front end to prevent damage to the threaded blade 5. It can effectively clean the surface of the threaded blade 5 and the chips and debris in the collection groove 7, thereby clearing the blocked parts and avoiding the decrease in chip removal efficiency or equipment failure due to blockage. This mechanism is different from the traditional spiral chip conveyor, which is prone to blockage due to chip accumulation or overload, and keeps the system running smoothly.
