Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding machine safety technology, specifically a grinding machine safety detection device. Background Technology
[0002] The inherent working characteristics of grinding machines bring potential risks. As the core component of a grinding machine, the grinding wheel typically operates at extremely high speeds; for example, the grinding wheel of a high-speed precision grinding machine can reach speeds of thousands of revolutions per minute or even higher. Under such high-speed rotation, if the grinding wheel has quality problems, such as manufacturing defects, uneven wear, or improper installation, it is very easy to break. The resulting high-speed fragments have enormous destructive power and can cause serious personal injury to operators.
[0003] Existing grinding machine safety protection often uses protective covers to reduce risks. To ensure the protective effect, they are often designed to be relatively closed. Although they effectively block the flying of fragments from broken grinding wheels, when frequently changing workpieces, operators need to frequently open and close the protective covers. The operation is cumbersome, consumes a lot of time and energy, and greatly reduces production efficiency. Summary of the Invention
[0004] The purpose of this invention is to provide a grinding machine safety detection device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding machine safety detection device, comprising:
[0006] A fixed compartment, on which a protective cover is fixedly connected;
[0007] A protective assembly, placed inside a fixed compartment, includes a connecting block slidably connected to the fixed compartment, a first sliding rod fixedly connected to the connecting block, a fixed frame fixedly connected to the first sliding rod, a first transmission frame slidably connected to the first sliding rod, a second sliding rod fixedly connected to the bottom of the first transmission frame, a sliding block fixedly connected to the second sliding rod, a second transmission frame slidably connected to the second sliding rod, a transmission block slidably connected to the second transmission frame, a lifting rod fixedly connected to the transmission block, a protective plate fixedly connected to the lifting rod, and an electric telescopic rod fixedly connected to the connecting block.
[0008] A rotating block is placed on top of a fixed chamber and is rotatably connected to a first transmission frame. A lead screw is fixedly connected to the rotating block, and a clamping frame is threaded onto the lead screw. A motor is fixedly connected inside the fixed frame, and a grinding block is fixedly connected to the output end of the motor.
[0009] Furthermore, the end of the electric telescopic rod furthest from the connecting block is fixedly connected to the fixed compartment.
[0010] The above technical solution is adopted: by setting an electric telescopic rod, it is convenient to drive the connecting block to slide.
[0011] Furthermore, the fixed chamber has an oblique hole, and the second sliding rod is slidably connected in the oblique hole on the fixed chamber. The second transmission frame has a horizontal hole, and the second sliding rod is slidably connected in the horizontal hole on the second transmission frame.
[0012] The above technical solution is adopted: by setting an oblique hole and opening a horizontal hole on the second transmission frame, when the second sliding rod slides, it will drive the sliding block to slide on the second transmission frame, so that the second transmission frame is displaced by transmission.
[0013] Furthermore, an installation frame is fixedly connected to the fixed compartment.
[0014] The above technical solution is adopted: by fixing the mounting frame to the fixed compartment, it is convenient to fix the device during use.
[0015] Furthermore, the fixed chamber has an opening, and the protective plate is slidably connected to the opening on the fixed chamber.
[0016] The above technical solution is adopted: by opening the fixed compartment, the protective plate is avoided during use.
[0017] Furthermore, there are two clamping frames, both of which are threaded onto the lead screw, and the two clamping frames are threaded onto the lead screw in opposite directions.
[0018] The above technical solution is adopted: by setting the two clamping frames to have opposite threaded connections on the lead screw, it is convenient to drive the two clamping frames to clamp each other and move away from each other during use.
[0019] Furthermore, a guide rail is fixedly connected to the lifting rod, and an opening is provided on the second sliding rod, with the second sliding rod fixedly connected to the opening on the second sliding rod.
[0020] The above technical solution is adopted: by setting a guide rail, when the second sliding rod slides to a position close to the protective plate, the guide rail is driven to rise under the action of the transmission block, which limits the second sliding rod until the top of the transmission block abuts against the top of the inner wall of the fixed chamber near the guide rail, thus preventing the second sliding rod from disengaging from the inclined hole on the fixed chamber.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] 1. In this utility model, when the electric telescopic rod is activated, it drives the connecting block to slide on the fixed chamber. The movement of the connecting block is transmitted to the second transmission frame via the first transmission frame and the second sliding rod, causing the second transmission frame to squeeze the transmission block. The transmission block drives the protective plate to rise, thus shielding the operator from the front and preventing fragments from flying and injuring the operator. The lifting of the protective plate occurs after the workpiece in the first transmission frame approaches the grinding block during grinding, eliminating the need for the operator to frequently open and close the protective plate. This solves the problem in the prior art where the operator needs to frequently open and close the protective plate.
[0023] 2. Once displacement of the grinding block is detected, it means that there may be dangerous situations such as grinding wheel breakage or uneven wear. In this utility model, the displacement sensor can immediately send a signal to the electric telescopic rod. This signal transmission is based on the built-in electrical transmission circuit. The electric telescopic rod quickly receives the instruction and drives the connecting block to slide, so that the workpiece is quickly away from the grinding block. It takes proactive avoidance measures at the moment the danger first appears, effectively reducing the risk of grinding block fragments splashing and ensuring the safety of operators and equipment.

[0033] 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. Example
[0034] like Figures 1-4 As shown, this utility model provides a technical solution: a grinding machine safety detection device, comprising:
[0035] Fixed compartment 1, with a protective cover 11 fixedly connected to it;
[0036] Protective component 2 is placed inside fixed compartment 1. Protective component 2 includes a connecting block 23 slidably connected to fixed compartment 1, a first sliding rod 24 fixedly connected to connecting block 23, a fixed frame 21 fixedly connected to the first sliding rod 24, a first transmission frame 22 slidably connected to the first sliding rod 24, a second sliding rod 210 fixedly connected to the bottom of the first transmission frame 22, a sliding block 25 fixedly connected to the second sliding rod 210, a second transmission frame 26 slidably connected to the second sliding rod 210, a transmission block 27 slidably connected to the second transmission frame 26, a lifting rod 28 fixedly connected to the transmission block 27, a protective plate 211 fixedly connected to the lifting rod 28, and an electric telescopic rod 29 fixedly connected to connecting block 23.
[0037] Rotating block 3 is placed on top of fixed chamber 1. Rotating block 3 is rotatably connected to first transmission frame 22. A lead screw 31 is fixedly connected to rotating block 3. A clamping frame 32 is threadedly connected to lead screw 31. A motor 33 is fixedly connected inside fixed frame 21. A grinding block 34 is fixedly connected to the output end of motor 33.
[0038] In this invention, the electric telescopic rod 29 is activated, which drives the connecting block 23 to slide on the fixed chamber 1. The movement of the connecting block 23 is transmitted to the second transmission frame 26 via the first transmission frame 22 and the second sliding rod 210, causing the second transmission frame 26 to press against the transmission block 27. The transmission block 27 then lifts the protective plate 211, thus shielding the operator from the front and preventing injury from flying debris. The lifting of the protective plate 211 occurs after the workpiece in the first transmission frame 22 approaches the grinding block 34 during grinding, eliminating the need for the operator to frequently open and close the protective plate 211. This solves the problem in the prior art where the operator needs to frequently open and close the protective plate 211.
[0039] Furthermore, such as Figures 1 to 4As shown, one end of the electric telescopic rod 29 away from the connecting block 23 is fixedly connected to the fixed chamber 1. The electric telescopic rod 29 facilitates the sliding of the connecting block 23.
[0040] The fixed chamber 1 has an oblique hole, and the second sliding rod 210 is slidably connected in the oblique hole on the fixed chamber 1. The second transmission frame 26 has a horizontal hole, and the second sliding rod 210 is slidably connected in the horizontal hole on the second transmission frame 26. By providing the oblique hole and the horizontal hole on the second transmission frame 26, when the second sliding rod 210 slides, it will drive the sliding block 25 to slide on the second transmission frame 26, so that the second transmission frame 26 is displaced by transmission.
[0041] A mounting frame 4 is fixedly connected to the fixed compartment 1, which makes it convenient to fix the device during use.
[0042] The fixed compartment 1 has an opening, and the protective plate 211 is slidably connected to the opening in the fixed compartment 1. By having an opening in the fixed compartment 1, the protective plate 211 is prevented from being blocked during use.
[0043] There are two clamping frames 32, both of which are threaded onto the lead screw 31. The two clamping frames 32 are threaded onto the lead screw 31 in opposite directions. By setting the two clamping frames 32 to be threaded onto the lead screw 31 in opposite directions, it is convenient to drive the two clamping frames 32 to clamp each other and move away from each other during use.
[0044] The above solution also has the problem that when the second sliding rod 210 slides on the fixed chamber 1, it may deviate when it contacts the opening on the fixed chamber 1, such as... Figure 2 As shown, a guide rail is fixedly connected to the lifting rod 28, and an opening is provided on the second sliding rod 210. The second sliding rod 210 is fixedly connected in the opening on the second sliding rod 210. By providing the guide rail, when the second sliding rod 210 slides to a position close to the protective plate 211, the guide rail is driven to rise under the action of the transmission block 27, which limits the second sliding rod 210 until the top of the transmission block 27 abuts against the top of the inner wall of the fixed chamber 1 near the guide rail, thus preventing the second sliding rod 210 from dislodging from the inclined hole on the fixed chamber 1.
[0045] Working principle: such as Figures 1-4 As shown;
[0046] In use, the workpiece is clamped on the clamping frame 32. The electric telescopic rod 29 is activated, which drives the connecting block 23, the first sliding rod 24, and the fixed frame 21 and the first transmission frame 22 connected thereto to move as a whole toward the grinding block 34, thereby sending the workpiece toward the grinding block 34.
[0047] Simultaneously, the movement of the first transmission frame 22 causes the second sliding rod 210 at its bottom to slide along the inclined hole on the fixed chamber 1. The second sliding rod 210 drives the second transmission frame 26 to move within the fixed chamber 1 via the sliding block 25 on it. The displacement of the second transmission frame 26 compresses the transmission block 27 slidably connected to it, forcing the transmission block 27 to drive the lifting rod 28 and the protective plate 211 to rise vertically, forming a protective barrier.
[0048] Therefore, the lifting of the protective plate 211 and the feeding of the workpiece are driven by the same electric telescopic rod 29 and completed synchronously. When the workpiece contacts the grinding block 34 for processing, the protective plate 211 is already in the protective position.
[0049] When the displacement sensor detects abnormal displacement of the grinding block 34, it immediately sends a signal to the electric telescopic rod 29 to drive the workpiece to retract quickly.
[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
