Description

Technical Field

[0001] This utility model relates to the field of machining center technology, and in particular to a lifting guard assembly for machining centers. Background Technology

[0002] A machining center is a high-efficiency automated machine tool composed of mechanical equipment and a CNC system, suitable for processing complex parts. CNC machining centers are among the world's most produced and widely used CNC machine tools. They have strong comprehensive processing capabilities, and can complete a lot of processing after a workpiece is clamped once. They also have high processing accuracy. To protect internal components such as lead screws, lifting guard assemblies are installed on the machine tool to prevent external debris, dust, water, etc. from entering the machine tool during processing.

[0003] However, existing technologies have some problems: although existing lifting guards can extend and retract with the movement of the machine tool slide to protect internal components such as lead screws, in actual use, the two ends of the lifting guard need to be connected to the machine tool and the machine tool slide respectively. The connection method is usually bolted. Therefore, when the operator needs to disassemble the lifting guard to inspect or maintain the machine tool, multiple sets of bolts need to be removed with tools, and then the bolts need to be reset during installation. This operation is cumbersome and reduces work efficiency. Therefore, we propose a lifting guard assembly for machining centers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lifting guard assembly for machining centers. By setting limit components and quick-release components, the guard body can be quickly loaded and unloaded, thereby improving the work efficiency of operators.

[0005] The purpose of this utility model is achieved as follows: A lifting guard assembly for a machining center includes a guard body, a block fixedly installed on the outer wall of the guard body, a horizontal plate movably inserted into the block, a vertical plate fixedly installed on the horizontal plate, a circular block fixedly connected to the vertical plate, and the other end of the circular block extending into a hole reserved in the machine tool slider. The horizontal plate and the block are also connected by a limiting assembly. The horizontal plate can move the circular block through the limiting assembly to release the limiting of the guard body. Through holes are opened on both sides of the guard body. The guard body and the machining tool are also connected by a quick-release assembly. The guard body can be removed from the machining tool through the quick-release assembly.

[0006] Optionally, the limiting component includes a guide rod, which is fixedly installed at the bottom of the block. A base plate is movably sleeved on the outer surface of the guide rod, and a diagonal rod is fixedly installed on the base plate. The diagonal rod is movably inserted into the horizontal plate.

[0007] Optionally, a stop block is fixedly connected to the bottom of the guide rod, and a first spring is movably sleeved on the outer surface of the guide rod, with the two ends of the first spring fixedly connected to the base plate and the stop block, respectively.

[0008] Optionally, the quick-release assembly includes a rocker arm rotatably connected to the machine tool, a pin movably inserted into the rocker arm, a pull handle fixedly connected to one end of the pin, and the other end of the pin passing through a through hole and extending into a pre-drilled hole in the machine tool.

[0009] Optionally, a second spring is movably sleeved on the outer surface of the pin, and the two ends of the second spring are respectively fixedly connected to the rocker arm and the pull handle.

[0010] Optionally, a sealing strip is fixedly installed on the protective cover body, and the thickness of the sealing strip is adapted to the thickness of the protective cover body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by setting up horizontal plates, vertical plates, circular blocks, limiting components, and quick-release components, allows workers to disassemble the protective cover body to inspect or maintain the machine tool's internal parts. The limiting components enable the two horizontal plates to move in opposite directions, causing the two circular blocks to move out of the pre-drilled holes in the machine tool's slider. The quick-release components then release the limiting on the bottom of the protective cover body, allowing for easy and quick disassembly. This facilitates maintenance and repair work, improving work efficiency. Attached Figure Description

[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] like Figures 1 to 6 As shown in the figure, the lifting guard assembly for a machining center provided in this embodiment of the utility model includes a guard body 1, a block 2 fixedly installed on the outer wall of the guard body 1, a horizontal plate 3 movably inserted into the block 2, a vertical plate 4 fixedly installed on the horizontal plate 3, a round block 5 fixedly connected to the vertical plate 4, and the other end of the round block 5 extending into a hole reserved in the machine tool slider. The horizontal plate 3 and the block 2 are also connected by a limiting component. The horizontal plate 3 can drive the round block 5 to move through the limiting component to release the limiting of the guard body 1. Through holes 6 are opened on both sides of the guard body 1. The guard body 1 and the machining tool are also connected by a quick-release component. The guard body 1 can be removed from the machining tool through the quick-release component.

[0022] Workers use quick-release components to fix the bottom of the protective cover body 1 to the machine tool, and use limiting components to fix the top of the protective cover body 1 to the machine tool slider. When the machine tool slider slides up and down to drive the cutting tool, the protective cover body 1 can extend and retract with the sliding of the machine tool slider, thereby protecting the internal components such as the lead screw. If the protective cover body 1 gets stuck or the machine tool needs maintenance, workers can quickly remove the protective cover body 1 using the limiting components and quick-release components, which facilitates maintenance and repair work and improves work efficiency.

[0023] Furthermore, the limiting component includes a guide rod 7, which is fixedly installed at the bottom of the block 2. A base plate 8 is movably sleeved on the outer surface of the guide rod 7. A diagonal rod 9 is fixedly installed on the base plate 8 and is movably inserted into the horizontal plate 3.

[0024] When the operator needs to remove the round block 5 from the reserved hole of the machine tool slider, the base plate 8 can be moved downward, which can drive the inclined rod 9 to move downward, thereby causing the outer surface of the inclined rod 9 to press against the horizontal plate 3, causing the two horizontal plates 3 to drive the two vertical plates 4 to move in opposite directions, thereby causing the two round blocks 5 to move in opposite directions and move out of the reserved hole of the machine tool slider, thus releasing the restriction on the protective cover body 1 and facilitating the disassembly of the protective cover body 1.

[0025] Furthermore, a stop block 10 is fixedly connected to the bottom of the guide rod 7, and a first spring 11 is movably sleeved on the outer surface of the guide rod 7. The two ends of the first spring 11 are fixedly connected to the base plate 8 and the stop block 10, respectively.

[0026] By setting the first spring 11 to a compressed state, the base plate 8 will tend to move upward due to the elastic force of the first spring 11, thereby enabling the round block 5 to be stably held in the reserved hole of the machine tool slider, and thus stably maintaining the limiting effect on the protective cover body 1.

[0027] Furthermore, the quick-release assembly includes a rocker arm 12, which is rotatably connected to the machine tool. A pin 13 is movably inserted into the rocker arm 12. One end of the pin 13 is fixedly connected to a pull handle 14, and the other end of the pin 13 passes through the through hole 6 and extends into a reserved hole in the machine tool.

[0028] When the staff needs to remove the protective cover body 1 from the machine tool, they can pull the pin 13 through the handle 14 to pull the pin 13 out of the machine tool reserved hole and through hole 6, and then rotate the rocker arm 12 downward to release the limit on the protective cover body 1, so as to facilitate the removal of the protective cover body 1.

[0029] Furthermore, a second spring 15 is movably sleeved on the outer surface of the pin 13, and the two ends of the second spring 15 are respectively fixedly connected to the rocker arm 12 and the pull handle 14.

[0030] By setting the second spring 15 to a stretched state, the elastic force of the second spring 15 will cause the pull handle 14 to tend to move closer to the rocker arm 12, thereby enabling the pin 13 to be stably held in the machine tool reserved hole, so as to ensure the stable limiting effect on the protective cover body 1.

[0031] Furthermore, a sealing strip 16 is fixedly installed on the protective cover body 1, and the thickness of the sealing strip 16 is adapted to the thickness of the protective cover body 1.

[0032] The sealing strip 16 can be made of rubber. Since the entire shield body 1 is composed of multiple individual shield bodies 1, by installing the sealing strip 16 at the bottom of an individual shield body 1 and attaching the sealing strip 16 to the surface of the adjacent individual shield bodies 1, the sealing performance at the joints of the shield body 1 can be improved, thereby enhancing the protective effect.

[0033] Working principle and usage process of this utility model: When the machine tool slides up and down to drive the cutting tool, the protective cover body 1 can extend and retract along with the slide of the machine tool slide, thereby protecting the internal components such as the lead screw. If the protective cover body 1 gets stuck or the machine tool needs maintenance, the operator can move the base plate 8 downward, which will drive the inclined rod 9 downward. This will cause the outer surface of the inclined rod 9 to press against the horizontal plate 3, causing the two horizontal plates 3 to drive the two vertical plates 4 to move in opposite directions. This will cause the two round blocks 5 to move out of the reserved holes in the machine tool slide, thereby releasing the restriction on the top of the protective cover body 1. Then, by pulling the pull handle 14, the pin 13 is pulled out from the reserved hole and through hole 6 of the machine tool. Then, the swing arm 12 is rotated downward to release the restriction on the protective cover body 1, so as to facilitate the disassembly of the protective cover body 1. This is convenient and quick, which facilitates the maintenance and repair work of the operator and improves work efficiency.

[0034] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
