Description

Technical Field

[0001] This utility model relates to the technical field of chip removal in machining centers, and more particularly to a bed that facilitates chip removal. Background Technology

[0002] The chip removal device on the machining center bed is an indispensable auxiliary device in machine tool operation. Its core function is to efficiently collect and remove the mixture of metal chips, grinding powder, and cutting fluid generated during machining. This device typically integrates technologies such as negative pressure suction, spiral conveying, solid-liquid separation, and automatic control. Through installation design close to the cutting area (such as the bed water return tank or the side of the worktable), it achieves immediate chip removal.

[0003] In the chip removal channel of the chip removal device, the mixture of chips and cutting fluid adheres to the channel surface, which increases the chip removal resistance and the risk of jamming. Therefore, it is necessary to install a corresponding water spray device to clean the chip removal channel, dilute the impurities in the chips, and flush the cutting fluid to the filter unit.

[0004] The existing chip removal channel adopts an inclined structure design, which uses gravity to guide the chips to slide down naturally. At the same time, a water spray device forms a directional water flow on the inclined surface. The water flow dilutes the mixture of chips and cutting fluid generated during the cutting process through the flushing action, reduces the viscosity of the mixture, prevents chips from sticking and accumulating, ensures that the chips are smoothly discharged along the inclined surface, and improves chip removal efficiency and equipment operation stability.

[0005] However, in actual use, long, curled chips or chips that become heavier after being moistened still tend to get stuck in the chip removal channel, affecting the chip removal effect. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art that chips still get stuck in the chip removal channel when dealing with long, curled chips or chips that become heavier after being moistened, thus affecting the chip removal effect.

[0007] To achieve the above objectives, this application proposes a bed that facilitates chip removal, comprising:

[0008] bed body;

[0009] An integrated chip removal system is provided on one side of the bed body, and the integrated chip removal system includes:

[0010] A protective outer shell is fixed to the side of the bed body.

[0011] A flushing pipe extends through the top of the sidewall of the protective housing;

[0012] The segmented inclined chip guide groove is arranged inclined downward along the water outlet of the flushing pipe inside the outer shell. The chip guide groove is provided with multiple sets of modular chip guide units. Each set of chip guide units includes: a fixed chip guide base plate, which is rigidly fixed to the inner wall of the outer shell.

[0013] The movable chip guide flap is connected to the fixed chip guide base plate at a variable angle via a hinge shaft, and its end is mounted on the receiving end of the adjacent set of fixed chip guide base plates.

[0014] Angle adjustment mechanism includes: a linkage rod, configured corresponding to each set of movable chip guide flaps, with both ends of the linkage rod connected to the bottom of the flap and the bottom surface of the housing respectively via ball joints; a main drive linkage rod, arranged parallel to the bottom surface of the housing, with the middle part of the linkage rod forming a kinematic pair with the main drive linkage rod via a spherical bearing; and a double-acting hydraulic cylinder, with the piston rod of the hydraulic cylinder connected to the main drive linkage rod.

[0015] This application achieves pulse flushing of chips through the synergistic effect of a segmented inclined chip guide groove and a hydraulic reciprocating angle adjustment mechanism. The hydraulic cylinder piston rod is connected to the main connecting rod, and the reciprocating motion drives the main connecting rod to deflect the split connecting rod, thereby adjusting the angle between the movable chip guide flap and the fixed chip guide base plate. This throttles and releases the liquid in the chip guide groove, achieving pulse flushing. This solves the problem in the prior art where long, curled chips or chips that become heavier after being moistened still remain in the chip removal channel, affecting the chip removal effect.

[0016] Furthermore, in order to facilitate observation of chip retention and maintenance of the chip removal device, the protective shell is open, forming a semi-enclosed chip removal space.

[0017] Furthermore, the top of the open protective shell is arranged horizontally through, and the water inlet end of the flushing pipe extends to the upper part of the high-end water inlet side of the segmented inclined chip guide groove, forming a flushing coverage area parallel to the direction of the chip guide groove.

[0018] Furthermore, in order to achieve a smooth transition between multiple sets of modular chip guiding units, the receiving end of the upstream moving chip guiding flap is provided with a flow guiding weir plate.

[0019] Furthermore, to avoid interference between the drive unit and the water circulation channel, the double-acting hydraulic cylinder is located at the end of the main drive connecting rod near the water tank.

[0020] Furthermore, in order to store the flushing fluid, a booster water tank is installed at the water inlet of the flushing pipe, which is equipped with a booster pump and a liquid level sensor.

[0021] Furthermore, in order to facilitate the collection of the mixed liquid after rinsing, a chip discharge manifold is provided on the water outlet side at the lower end of the chip guide channel.

[0022] Furthermore, to facilitate solid-liquid separation of the mixed liquid after rinsing, the outlet of the chip discharge manifold is connected to a solid-liquid separation chip collection box.

[0023] Furthermore, in order to limit the adjustment range of the movable chip guide flap and the fixed chip guide base plate, the included angle between the movable chip guide flap and the fixed chip guide base plate is adjusted to a range of 0°~15°. When the included angle is >0°, a turbulent pressurization zone is formed between the guide weir plate and the movable chip guide flap.

[0024] The beneficial effects of this application are as follows:

[0025] 1. This application achieves pulse flushing of chips through the synergistic effect of a segmented inclined chip guide groove and a hydraulic reciprocating angle adjustment mechanism. The hydraulic cylinder piston rod is connected to the main connecting rod, and the reciprocating motion drives the main connecting rod to deflect the split connecting rod, thereby adjusting the angle between the movable chip guide flap and the fixed chip guide base plate. This throttles and releases the liquid in the chip guide groove, achieving pulse flushing. This solves the problem in the prior art where long, rolled chips or chips that become heavier after being moistened still remain in the chip discharge channel, affecting the chip discharge effect.

[0026] 2. This application is equipped with a pressurized water supply tank, a chip discharge manifold, and a solid-liquid separation chip collection box, forming a complete flushing fluid circulation system. It can be used independently without the water supply system, and has a simple structure and is easy to operate.

[0027] 3. The chip removal device of this application can perform continuous chip removal and pulse chip removal. The two combinations can realize diversified adjustment of chip removal mode. The open protective shell not only facilitates the maintenance of the chip removal device, but also allows timely observation of the chip retention in the channel, so as to select the appropriate chip removal mode for chip removal.

[0041] The following will be combined with the appendix Figures 1-2 The embodiments of the technical solutions of this application are described in detail below. The following embodiments are only used to more clearly illustrate the technical solutions of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0042] Implementation Method 1:

[0043] like Figures 1-2 This illustration depicts a machine bed designed for easy chip removal. To achieve pulse-jet cleaning, this embodiment utilizes an integrated chip removal system 2. The segmented inclined chip guide groove 4 and the angle adjustment mechanism 9 work in concert. The chip guide groove 4 consists of multiple modular chip guide units, each including a fixed chip guide base plate 41 and a movable chip guide flap 42. The fixed chip guide base plate 41 is rigidly fixed to the inner wall of the protective housing 3. The movable chip guide flap 42 is connected to the fixed chip guide base plate 41 at a variable angle via a hinge shaft, and its end rests on the receiving end of an adjacent fixed chip guide base plate 41. In the angle adjustment mechanism 9, the two ends of the linkage rod 91 are connected by ball joints to the bottom of the movable chip guide flap 42 and the bottom surface of the protective housing 3. The main drive linkage rod 92 is arranged parallel to the bottom surface of the housing 3 and forms a kinematic pair with the linkage rod 91 via a spherical bearing. The piston rod of the double-acting hydraulic cylinder 93 is connected to the main drive linkage rod 92.

[0044] When the hydraulic cylinder 93 drives the main drive linkage 92 to reciprocate, the linkage 91 drives the movable chip guide flap 42 to deflect around the hinge axis, causing the angle between the movable chip guide flap 42 and the fixed chip guide base plate 41 to change periodically within the range of 0° to 15°. When the angle is greater than 0°, a turbulent pressurization zone A is formed between the guide weir plate 43 and the movable chip guide flap 42, which throttles and releases the cutting fluid on the chip guide groove 4, generating pulsed water flow impact, effectively breaking up long rolled chips and preventing chip adhesion, thus solving the problem of long rolled chips stagnation in traditional inclined chip removal channels. The protective shell 3 adopts an open design, forming a semi-enclosed chip removal space, which facilitates observation of chip accumulation and equipment maintenance. That is, the open protective shell 3 facilitates real-time monitoring of the working status of the turbulent pressurization zone A, and achieves dynamic switching between continuous chip removal and pulse chip removal modes by adjusting the stroke frequency of the hydraulic cylinder 93.

[0045] Implementation Method Two:

[0046] like Figures 1-2 This illustration depicts a machine bed designed for easy chip removal. To achieve a smooth transition between the multi-stage guide weirs and the modular chip guide units, and to ensure stable delivery of chips and cutting fluid on the segmented chip guide groove 4, a guide weir 43 is provided at the receiving end of the upstream movable chip guide flap 42. The guide weir 43 is vertically fixed to the end of the movable chip guide flap 42, and its height matches the receiving end of the adjacent fixed chip guide base plate 41. When the angle of the movable chip guide flap 42 changes, the guide weir 43 always forms a continuous guiding surface with the downstream fixed chip guide base plate 41, preventing chips from getting stuck between the modular chip guide units. The open structure of the protective shell 3 further facilitates manual cleaning of the chip guide groove 4, especially when the chips are large or have high humidity. Tools can be used to directly intervene in the area of ​​the guide weir 43, enhancing the reliability of chip removal.

[0047] Implementation Method 3:

[0048] like Figures 1-2 This illustration depicts a machine bed designed for easy chip removal. To prevent interference between the hydraulic drive unit and other components, particularly between the angle adjustment mechanism 9 and the flushing pipe 5 and the cutting fluid circulation system, a double-acting hydraulic cylinder 93 is positioned near the water tank end of the main drive linkage 92. This arrangement keeps the hydraulic cylinder 93 away from the flushing coverage area on the high-end water inlet side of the chip guide groove 4, preventing high-pressure water from directly impacting the hydraulic components. Simultaneously, the main drive linkage 92 is arranged parallel to the bottom surface of the protective housing 3, and the ball joint connection point of the linkage 91 is located in the low-lying area of ​​the inner wall of the housing 3, ensuring that the angle adjustment action is not affected by chip accumulation and improving the operational stability of the equipment.

[0049] Implementation Method Four:

[0050] like Figures 1-2This illustration depicts a machine bed designed for easy chip removal. To achieve an independent pressurized water supply and solid-liquid separation system, the inlet end of the flushing pipe 5 is connected to a pressurized water tank 6, which houses a built-in pressurized pump and a level sensor, enabling it to independently provide high-pressure water flow. The pressurized water tank 6 is connected to the high-end inlet side of the segmented chip guide trough 4 via a pipe, forming a flushing coverage area parallel to the direction of the chip guide trough 4, ensuring that the chips are sufficiently diluted in the initial stage. A chip discharge manifold 7 is installed at the low-end outlet side of the chip guide trough 4 to collect the flushed cutting fluid and chip mixture and transport it to the solid-liquid separation chip collection box 8. The solid-liquid separation chip collection box 8 is equipped with a filter screen and a sedimentation area to achieve automatic separation of chips and cutting fluid. The cutting fluid can be returned to the pressurized water tank 6 for recycling, forming an independent and closed flushing fluid circulation system, reducing dependence on external water supply.
