[0002] The chip removal device of the machine tool worktable is an indispensable component in mechanical processing equipment such as CNC machine tools, modular machine tools, assembly lines, automatic lines, etc. Its main function is to quickly and effectively discharge the chips generated during the processing from the worktable area to ensure the normal operation and processing accuracy of the machine tool.

[0003] A chip removal device for a CNC machine tool disclosed in a patent application with reference publication number CN109434553B concentrates iron chips by setting an adsorption rod and performs primary and secondary chip removal on the adsorption rod by setting a scratching device. At the same time, the magnetic groove is removed by the first chip removal bar, with good chip removal effect and low noise.

[0004] A comprehensive analysis of the above patents reveals the following defects: At present, a large amount of cutting fluid is also discharged when the machine tool removes chips. Although most of the cutting fluid and cutting waste can be separated during the chip removal process of the traditional chip removal device, a large amount of cutting fluid is still attached to the surface of the cutting waste. When the cutting waste is left to stand and pile up, the cutting fluid attached to the surface will continue to leak out for a long time, resulting in the inability to further process and utilize the cutting waste. Secondly, there are still large gaps between the cutting waste, which causes the cutting waste to occupy a large amount of storage space and is distributed in a dispersed state, which increases the difficulty of storing and transporting the cutting waste; Therefore, the present invention proposes a chip removal device and a chip removal method for a machine tool worktable to solve the above problems.

[0016] The present invention provides a chip removal device and a chip removal method for a machine tool worktable. Compared with the prior art, it has the following beneficial effects: 1. A chip removal device and a chip removal method for a machine tool worktable. By setting up multiple chip removal mechanisms, the operation of continuously grabbing cutting waste chips and cutting fluid can be completed under the drive of a transmission component. After obtaining a mixture of cutting fluid and cutting waste chips, the cutting fluid and cutting waste chips can be separated to achieve preliminary drying treatment of the cutting waste chips. After the cutting fluid and cutting waste chips are separated, the cutting waste chips can be squeezed so that the cutting fluid remaining on the surface of the cutting waste chips can be squeezed out to complete the secondary separation of the cutting waste chips and the cutting fluid, so as to achieve the purpose of drying treatment of the cutting waste chips, so that the discharged cutting waste chips are close to a dry state, which is more convenient for storage and transportation, and the cutting fluid can be collected, processed and utilized again after being separated.

[0017] 2. A chip removal device and method for a machine tool worktable. By arranging an auger, a long strip push plate and a sealing component in the chip removal mechanism, the sealing component can be used to seal the discharge port of the filter cartridge after the chip removal mechanism collects the cutting waste. The auger can push the cutting waste to move in a directional manner during continuous operation, so that the cutting waste chips are squeezed against each other, reducing the gaps between the cutting waste chips. While squeezing out the cutting fluid on the surface of the cutting waste chips, the effect of reducing the storage space of the cutting waste can be achieved, so that more cutting waste chips can be stored in a smaller storage space. Due to the reduction in volume, the cutting waste chips are more convenient for subsequent storage and transportation.

[0018] 3. A chip removal device and a chip removal method for a machine tool worktable. Each chip removal mechanism operates relatively independently. After one of the chip removal mechanisms fails, the chip removal mechanisms at other positions can still operate relatively independently, which will not affect the chip removal process. Compared with a traditional machine tool chip removal device, it is more practical. Secondly, a plurality of chip removal mechanisms and a drive rack one, a drive rack two, a drive rack three and a long strip push plate are linked to drive the chip removal mechanism to obtain cutting waste and cutting fluid at a preset position, and automatically squeeze the cutting waste in the subsequent conveying process. Therefore, there is no need to set up a separate drive device for the chip removal mechanism to grab the cutting waste and squeeze the cutting waste. Only one servo motor is required to drive the entire chip removal device to operate, thereby saving the cost of setting up the drive device. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Embodiment 2: The main difference between this embodiment and the first technical solution is that: a chip removal device for a machine tool worktable, the chip removal mechanism 9 includes an outer cylinder assembly, an inner cylinder assembly and a plugging assembly, the inner cylinder assembly is arranged inside the outer cylinder assembly, and is used to separate the cutting fluid and the metal waste, and the plugging assembly is used to plug one end of the inner cylinder assembly to prevent the un-extruded metal waste from being discharged.

A spring 918 is slidably sleeved on the outer wall of the telescopic column 916 and located between the opposite side walls of the adjustment hole 915 and the spring retaining ring 917. A baffle plate 919 is fixedly arranged at one end of the plurality of telescopic columns 916 away from the filter cylinder 96. The end of the filter cylinder 96 close to the baffle plate 919 is a discharge port for discharging metal scraps. When the baffle plate 919 is not subjected to external force, the discharge port is in an open state, that is, the metal scraps can be discharged through the discharge port.An annular partition plate 911 is fixedly arranged between the inner wall of the protective cylinder 91 and the outer wall of the filter cylinder 96. A sealing plate 910 is fixedly arranged on the inner walls of both sides of the chip inlet 1 92 and the chip inlet 2 97 at relative positions, which is used to isolate the chambers of the protective cylinder 91 and the filter cylinder 96 from each other, and form a chip feed channel between the two sealing plates 910 to ensure that the metal waste chips and cutting fluid after passing through the chip inlet 1 92 enter the filter cylinder 96 through the chip feed channel.

[0024] The present invention also provides a chip removal method for a chip removal device of a machine tool worktable, which is used for the chip removal device of the machine tool worktable, and the method comprises the following steps: Step 1: Granular metal waste and cutting fluid generated by machine tool cutting metal parts fall to the bottom of the inner cavity of the chip collecting bucket 2 under the action of gravity, and gather into the groove 7 under the action of gravity; the specific process is: the cutting fluid and granular cutting debris fall to the bottom of the inner cavity of the chip collecting bucket 2 under the action of gravity, because the height of the side of the bottom of the inner cavity of the chip collecting bucket 2 away from the chip discharge frame 1 is higher than the other side, the chip collecting bucket 2 and the groove 7 are connected, and the highest position of the bottom of the groove 7 is still lower than the lower side of the bottom of the inner cavity of the chip collecting bucket 2, so the cutting fluid and granular cutting waste slide into the groove 7 for temporary storage; Step 2, the transmission assembly 8 drives multiple chip removal mechanisms 9 to run at a low and uniform speed. When the chip removal mechanism 9 passes directly above the groove 7, the driving mechanism drives the chip removal mechanism 9 to grab part of the granular metal waste and the cutting fluid and enter it, separate the cutting fluid from the granular metal waste, and then squeeze the preliminarily dried granular metal waste to squeeze out the cutting fluid remaining in the metal waste. The specific process is: the chip removal mechanism 9 moves to the top of the groove 7 under the drive of the chain and the sprocket. At this time, the gear 1 95 and the drive rack 2 13 complete the meshing, and when the chip removal mechanism 9 continues to move, the drive rack 2 13 drives the gear 1 95 to rotate in a circle, thereby removing the chip. The chip mechanism 9 rotates as a whole. When one of the arc-shaped scrapers 93 rotates to the bottom, the bottom end of the arc-shaped scraper 93 contacts the bottom of the groove 7. Due to the arc-shaped structural design of the arc-shaped scraper 93, the arc-shaped scraper 93 is close to the chip inlet 1 92 and the arc surface is concave inward to form a funnel shape. Therefore, when the arc-shaped scraper 93 rotates in the direction of the funnel-shaped arc surface, it grabs part of the granular metal waste chips and cutting fluid through the chip inlet 1 92 and the chip inlet 2 97 and the chip inlet channel formed by the two sealing plates 910 and enters the filter cylinder 96. Since the groove 7 has a certain length, the chip removal mechanism 9 leaves after multiple grabbing in the groove 7. During the turning process of the chip removal mechanism 9, when the chip inlet 92 opens downward, the guide plate 9123 rotates under its own gravity, so that one end thereof abuts against the outer wall of the sealing plate 910 at the opposite position. At this time, the chip inlet channel is closed, and the waste chips entering the filter cylinder 96 cannot be discharged; Next, as the chip removal mechanism 9 continues to move toward the motor box 6, the baffle plate 919 contacts the slope surface at the bottom end of the long push plate 11 and climbs along the slope surface to the plane area of ​​the long push plate 11. As the baffle plate 919 climbs along the slope surface at one end of the long push plate 11, it gradually approaches from the end away from the chip removal port of the filter cartridge 96 and finally blocks the chip removal port of the filter cartridge 96. At this time, the spring retaining ring 917 squeezes the spring 918 to cause it to produce elastic deformation. Then, in the process that the chip removal mechanism 9 continues to move toward the motor box 6, the gear 2 99 first meshes with the driving rack 2 13, and then meshes with the driving rack 3 14; during the meshing connection between the gear 2 99 and the driving rack 2 13, the gear 2 99 continuously rotates under the drive of the driving rack 2 13, and the cutting fluid entering the filter cylinder 96 is discharged through the filter holes on its surface and the drainage holes on the surface of the protective cylinder 91, and the cutting fluid flows into the cutting fluid collection box 5 along the bottom of the cavity of the chip removal frame 1, and is discharged through the discharge pipe on the side wall of the cutting fluid collection box 5, and the metal waste chips inside the filter cylinder 96 are continuously pushed toward the adjustment hole 915 by the auger 98. Since the chip removal port of the filter cylinder 96 is blocked by the baffle plate 919, the granular metal waste chips are gradually squeezed out under the dual action of the auger 98 and the baffle plate 919, and the cutting fluid remaining in the granular metal waste chips is squeezed out; During the period when the gear 2 99 is meshed with the driving rack 3 14, since the driving rack 3 14 is installed above the guide tube 3, the driving rack 3 14 continues to drive the auger 98 to rotate, and in this area, the baffle plate 919 is separated from the surface of the long strip push plate 11, and the spring 918 pushes the spring baffle ring 917 to reset, and the baffle plate 919 moves away from the position close to the chip discharge port of the filter cartridge 96, and a gap of one end distance is formed between the baffle plate 919 and the chip discharge port of the filter cartridge 96, and the granular metal waste after being drained is pushed out by the auger 98 through the chip discharge port; Step 3: The granular metal waste separated from the cutting fluid is squeezed out through one end of the chip discharge mechanism 9 and then discharged along the guide pipe 3 under the action of its own gravity.
