Description

Technical Field

[0001] This utility model belongs to the technical field of waste chip carts, specifically relating to a waste chip cart for CNC machine tools. Background Technology

[0002] The chip cart for CNC machine tools is a metal chip collection and transportation device specifically designed for CNC machine tools. It is mainly used to collect metal waste such as chips and scraps generated during the processing.

[0003] Currently, most common waste chip carts on the market consist of a wheeled frame and an upward-opening box. The bottom of the box is rotatably connected to the frame via a rotating shaft. While this design is relatively simple, in actual use, because the box and frame are only rotatably connected on one side and lack a locking mechanism, the cart is prone to tipping forward unexpectedly when the metal scraps inside are unevenly distributed, or when encountering uneven surfaces or shaking during pushing. Once the cart tipps over, not only will the metal scraps scatter everywhere, affecting the cleanliness of the workshop and normal production order, but more importantly, it may cause serious injuries such as being struck by falling metal scraps to nearby operators, or even lead to more serious safety accidents.

[0004] Therefore, in order to solve the above problems, it is necessary to design a waste car for CNC machine tools. Utility Model Content

[0005] The purpose of this invention is to provide a waste chip cart for CNC machine tools to solve the technical problems mentioned in the background art.

[0030] The first buffer is adapted to contact the second buffer.

[0031] The beneficial effects of this utility model are:

[0032] (I) When the box is in a horizontal position, the limiting part is inserted into the hook part, and the box is locked and cannot rotate freely. When the box needs to rotate, the limiting part in the hook part is taken out. At this time, the hook part is not limited, and the box can rotate around one side of the bottom frame. Through the mechanical locking between the limiting part and the hook part, the box can be prevented from accidentally tipping over.

[0033] (II) When the box needs to be locked after it is flipped over to remove chips, the operator pushes the kicking device with their foot. The kicking device drives the connecting rod to slide in the first and second through holes. At the same time, the kicking device and the bottom frame compress the spring. The connecting rod drives the limiting device to slide in the square through hole. When the box is flipped to a horizontal position, the hook is in front of the limiting device.

[0051] In this embodiment, when the box 2 is in a horizontal position, the limiting member 402 is inserted into the hook member 401, and the box 2 is locked and cannot rotate freely. When the box 2 needs to rotate, the limiting member 402 inside the hook member 401 is removed. At this time, the hook member 401 is not limited, and the box 2 can rotate around one side of the bottom frame 1. Through the mechanical locking between the limiting member 402 and the hook member 401, the effect of preventing the box 3 from accidentally tipping over is achieved.

[0052] The top of the bottom frame 1 is provided with two fixed seats 5; the two fixed seats 5 are provided with a rotating shaft 6; the rotating shaft 6 is fitted with two bearing seats 7; the two bearing seats 7 are located inside the two fixed seats 5; the two bearing seats 7 are set at the bottom of the box body 2; it is preferred that the two fixed seats 5 and the two bearing seats 7 are symmetrically arranged; by setting the bearing seats 7, the box body 2 can be rotated around the rotating shaft 6 through the bearing seats 7.

[0053] The bottom frame 1 is provided with a pad 8; the pad 8 is provided with a square through hole 801; the limiting member 402 is disposed in the square through hole 801 and is slidably connected to the square through hole 801; wherein the limiting member 402 is adapted to the square through hole 801 is the most preferred option.

[0054] The pad block 8 has a first through hole 802; the bottom frame 1 has a second through hole 101; wherein the first through hole 802 is located below the square through hole 801 and is concentrically arranged with the second through hole 101; the locking assembly 4 further includes: a connecting rod 403, a spring 404 sleeved on the connecting rod 403, and a kicking member 405; wherein the connecting rod 403 is disposed in the first through hole 802 and the second through hole 101, and is slidably connected to the first through hole 802 and the second through hole 101; one end of the connecting rod 403 is connected to the limiting member 402, and the other end is connected to the kicking member 405; the spring 404... The two ends of the spring 404 contact the bottom frame 1 and the kick member 405 respectively; by setting the first through hole 802 and the second through hole 101, the connecting rod 403 is guided; the L-shaped limiting member 402 is the most preferred; the connecting rod 403 is used to transmit power; the spring 404 is used, and the two ends of the spring 401 contact the bottom frame 1 and the kick member 405 respectively, so as to keep the limiting member 402 automatically locked when there is no external force; the kick member 405 is used to facilitate foot triggering and realize the quick unlocking of the limiting member 402.

[0055] In this embodiment, when the box 2 needs to be locked after it is flipped to remove chips, the operator pushes the kicking component 405 with their foot. The kicking component 405 drives the connecting rod 403 to slide within the first through hole 802 and the second through hole 101. At the same time, the kicking component 405 and the bottom frame 1 compress the spring 404. The connecting rod 403 drives the limiting component 402 to slide within the square through hole 801. When the box 2 is flipped to a horizontal position, the hook component 401 is located in front of the limiting component 402. At this time, the kicking component 405 is released, the spring 404 deforms and rebounds, driving the kicking component 405 to reset. The kicking component 405 drives the connecting rod and the limiting component 402 to reset. The limiting component 402 is inserted into the hook component 401, forming a mechanical lock. Similarly, when the box 2 needs to be unlocked, the operator pushes the kicking component 405 with their foot, so that the limiting component 402 is located outside the hook component 401, thus achieving the effect of unlocking without the operator having to bend over manually.
