[0002] Mechanical equipment safety protection devices refer to a series of devices used to protect mechanical equipment operators, machine parts and the surrounding environment, aiming to meet safety and operational needs and reduce and avoid personal injury and material loss.

[0003] The existing patent publication number CN214162421U discloses a mechanical device with a safety protection device, including a base and an observation window. A connecting plate is installed on the upper left side of the base, and a protective plate is connected above the connecting plate. A handle is installed on one side of the protective plate. A placement plate is installed on the upper right side of the base, and a first sliding groove is provided inside the placement plate. A connecting block is installed inside the first sliding groove, and a fixing plate is connected above the connecting block. A cylinder is connected to one side of the fixing plate, and a moving plate is connected above the cylinder. A gear is installed inside the base, and a slider is installed above the gear. A drive motor is installed inside the slider, and a gear is connected to one side of the drive motor. This mechanical device with a safety protection device, by providing a connecting plate, closes the protective plate when the handle is pulled after the raw material is fixed, preventing injury to workers during the grinding process and thus protecting personnel safety.

[0004] During existing grinding processes, the resulting shavings can fly onto the operator's surface and cause injury. Therefore, protective covers are used before machining. However, these covers are manually operated, and workers may forget to put them on, leaving the operator unprotected. To address this problem, we propose a new safety protection device for mechanical equipment. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a safety protection device for mechanical equipment, which can solve the problem that when existing mechanical equipment is grinding, the waste generated during grinding will splash onto the operator's surface and cause injury. Therefore, protective covers are used to protect the operator before machining. However, since the existing protective covers are manually operated, the operator may forget to put on the protective cover due to negligence, thus losing the guarantee of safety protection.

[0007] To solve the above-mentioned technical problems, this utility model provides a safety protection device for mechanical equipment, which adopts the following technical solution: it includes a processing table, a fixed base is fixedly installed on the top of the processing table, and a moving component and a locking component are included above the fixed base;

[0008] The moving component includes two symmetrically positioned fixed frames, a sliding plate, and a limiting block. The two fixed frames are respectively fixedly installed at the front and rear ends of the top of the fixed base, and each of the two fixed frames has a sliding groove inside. A sliding plate is embedded and slidably arranged inside each of the two sliding grooves. A limiting block is fixedly installed on the left side of each of the two sliding plates. The limiting block is located inside the fixed frame. An opening is opened on the right side of each of the two fixed frames, and the right side of the sliding plate passes through the opening.

[0009] The locking assembly includes a connecting plate, a stop plate, a start switch, and a close switch. The connecting plate is fixedly installed between the front and rear sliding plates, the stop plate is fixedly installed at the bottom of the connecting plate, and the close switch and the start switch are respectively fixedly installed at the left and right ends of the top of the fixed base.

[0010] Optionally, a controller is fixedly installed on the front side of the fixed base, and the controller is electrically connected to both the start switch and the close switch. A clamping device is fixedly installed on the right side of the fixed base.

[0011] Optionally, the top of the processing table is provided with a slide rail, a movable seat is slidably arranged on the surface of the slide rail, a motor device is fixedly installed on the top of the movable seat, a grinding head is fixedly connected to the left output end of the motor device, and the motor device is electrically connected to the controller.

[0012] Optionally, a cylinder is fixedly installed on the top of the processing table, and a drive rod is fixedly connected to the output end of the cylinder. The end of the drive rod away from the cylinder is fixedly installed on the right side of the motor device.

[0013] Optionally, a protective cover is fixedly installed on the top of the connecting plate, and a handle is fixedly installed on the front side of the protective cover.

[0014] Optionally, a viewing window is fixedly installed inside the protective cover.

[0015] In summary, this utility model has at least one of the following beneficial effects: 1. By setting up a moving component, the worker can move the protective cover laterally by pulling the handle. When the protective cover moves to the rightmost end, the right side of the abutment plate below the connecting plate presses the start switch. The start switch can control the start of the motor device through the controller. This ensures that the worker must move the protective cover to the designated position before starting the mechanical equipment, thus avoiding the worker's negligence in not using the protective cover and improving work safety.

[0016] 2. By setting up cylinders and clamping devices, the grinding head can be moved and the parts to be ground can be fixed respectively. The addition of handles and viewing windows allows workers to observe the grinding process through the viewing window, while also preventing waste chips from flying. It is highly practical.
