Abstract
Description
A safety protection device for automotive parts processing Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically a safety protection device for automotive parts processing. Background Technology
[0002] Safety protection devices for automotive parts processing are used to ensure the safety of operators and the stable operation of equipment during the production process. They mainly use protective covers to physically isolate and shield moving parts, preventing personnel from coming into contact with high-speed rotating machinery, high-temperature parts, or flying debris. This can effectively reduce the risk of workplace injuries, ensure production efficiency and processing accuracy, and is an indispensable part of modern intelligent manufacturing workshops.
[0003] A safety protection device for machining mechanical parts, disclosed in Chinese Patent Publication No. CN218696611U, uses a first motor to drive a worm gear to rotate. A worm wheel drives a first rotating rod to rotate when the worm gear rotates, which in turn drives a threaded rod to rotate. The threaded rod can then raise and lower a protective cover. The protective cover can shield the waste generated during the machining of mechanical parts on the worktable. However, the safety protection device has a single function. While protecting the parts being machined, it occupies a large amount of space, thus affecting the flexibility of subsequent machining of automotive parts and the overall practicality of the protective device. Summary of the Invention
[0004] The purpose of this invention is to provide a safety protection device for the processing of automotive parts, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety protection device for processing automotive parts, comprising a processing table, a working groove provided in the middle of the upper surface of the processing table, a frame-shaped groove provided around the perimeter of the working groove, a protective frame provided inside the frame-shaped groove, the front end of the protective frame being made of tempered glass, a lifting mechanism provided inside the processing table for lifting the protective frame, a shielding mechanism provided at the left and right ends of the upper surface of the protective frame, and a clamping mechanism for clamping automotive parts in the working groove.
[0006] Preferably, the lifting mechanism includes a servo motor fixedly connected to the bottom left side of the processing table, a track shaft installed on the output shaft end of the servo motor, a connecting track externally meshing with the two track shafts, and a threaded rod fixedly connected to the top of the two track shafts and threadedly connected to the protective frame.
[0007] Preferably, there are two track shafts arranged opposite each other on the left and right sides inside the processing table, with the right track shaft rotating inside the processing table.
[0008] Preferably, the shielding mechanism includes motors installed inside the left and right sides of the upper surface of the protective frame, a take-up roller is installed at the output shaft end of the motor, a dustproof film is fixed to the outside of the take-up roller, and magnetic strips are fixed to the front and rear ends of the upper surface of the dustproof film.
[0009] Preferably, the dustproof film is wound in multiple rolls on the take-up roller, and the magnetic strips at the left and right ends of the upper surface of the protective frame are magnetically attracted to each other.
[0010] Preferably, the clamping mechanism includes a battery installed inside the bottom of the protective frame, one side of the battery being electrically connected to a conductive plate via a wire, charging heads being fixedly connected to both sides of the bottom of the frame-shaped groove for charging the battery, movable seats being provided on both sides inside the working groove, conductive blocks being provided on the outer side of the movable seats, a limiting slider being fixedly connected to one side of the lower surface of the movable seats and sliding within the working groove, and a first spring being fixedly connected to the inner side of the limiting slider.
[0011] Preferably, the movable seat has a movable groove in the center, a sliding block is slidably connected to one side of the movable groove, and connecting brackets are fixed to both ends of one side of the sliding block. Clamping blocks are detachably installed on one side of the two connecting brackets by bolts and nuts. A protective sleeve is provided inside the movable groove, the inside of the protective sleeve is filled with electrorheological fluid, and a second spring is horizontally fixed inside the protective sleeve.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This safety protection device for processing automotive parts has a lifting mechanism installed inside the processing table that can push the protective frame to rise and fall. When the protective frame is raised, it can push the movable seat in the working slot to move towards the center of the working slot. At this time, the clamping block on one side of the movable seat contacts the external part. The second spring inside the protective sleeve can be squeezed by the sliding block and the sliding block. Due to the reaction force of the second spring being squeezed, the clamping block can be pushed to fit against the outside of the automotive part to be processed by the sliding block and the connecting frame. When the protective frame is raised to the top, the energized piece on the protective frame fits against the conductive block on one side of the clamping mechanism. At this time, the battery can be energized by the electrorheological fluid in the movable seat of the conductive block leg. The electrorheological fluid solidifies quickly to fix the position of the clamping block, thereby stably clamping the automotive parts. While effectively protecting the lifting and lowering of the protective frame, it can also limit the clamping of the automotive parts after the protective frame is raised, improving the overall practicality and functionality of the safety protection device.
[0014] 2. This type of safety protection device for automotive parts processing has two sets of magnetic strips on the left and right sides of the top of the protective frame. When the protective frame is raised to its highest position, pulling the magnetic strips on the left and right sides of the upper surface will cause the dustproof film to be pulled out from the inside of the protective frame. At this time, the magnetic attraction of the left and right magnetic strips can complete the shielding and protection of the top of the protective frame, reducing the splashing of debris generated during automotive parts processing. At the same time, the gaps connecting the left and right magnetic strips allow processing components such as hydraulic rods to pass through, so as not to affect the normal processing of automotive parts. The motor inside the protective frame can start the winding roller to drive the dustproof film to be wound up, thereby quickly storing the dustproof film after use. Attached Figure Description

[0022] 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.
[0023] Please refer to Figures 1-6. This utility model provides two technical solutions:
[0024] Example 1: A safety protection device for processing automotive parts includes a processing table 1. A working groove 101 is provided in the middle of the upper surface of the processing table 1. A frame-shaped groove 102 is provided around the outer perimeter of the working groove 101. A protective frame 2 is provided inside the frame-shaped groove 102. The front end of the protective frame 2 is made of tempered glass. A lifting mechanism 3 is provided inside the processing table 1 for lifting the protective frame 2. A shielding mechanism 4 is provided at the left and right ends of the upper surface of the protective frame 2. The device also includes a clamping mechanism 6 for clamping the automotive parts in the working groove 101. The processing of the automotive parts inside the protective frame 2 can be observed through the front end of the protective frame 2. At the same time, the lifting of the protective frame 2 can effectively protect the processing of automotive parts. Furthermore, a limit block is provided on the outer side of the protective frame 2 to prevent the protective frame 2 from falling out of the processing table 1.
[0025] The lifting mechanism 3 includes a servo motor 301 fixed to the bottom left side of the processing table 1. A track shaft 302 is installed on the output shaft of the servo motor 301. A connecting track 303 is externally meshed with the two track shafts 302. A threaded rod 304 that is threaded to the protective frame 2 is fixedly connected to the top of the two track shafts 302. There are two track shafts 302 arranged opposite each other on the left and right sides inside the processing table 1. The right track shaft 302 rotates inside the processing table 1. When the servo motor 301 is started, it can drive the left track shaft 302 inside the processing table 1 to rotate. At this time, the track shaft 302 can drive the right track shaft 302 inside the processing table 1 to rotate synchronously through the connecting track 303. At this time, the two track shafts 302 can drive the connecting track 303 at the top to rotate inside the protective frame 2 and push the protective frame 2 to lift.
[0026] The clamping mechanism 6 includes a battery 201 installed inside the bottom of the protective frame 2. One side of the battery 201 is electrically connected to the conductive plate 202 via a wire. Charging heads 103 are fixed to both sides of the bottom of the frame-shaped groove 102 for charging the battery 201. Movable seats 601 are provided on both sides inside the working groove 101. Conductive blocks 602 are provided on the outer side of the movable seats 601. A limiting slider 603 that slides in the working groove 101 is fixed to one side of the lower surface of the movable seats 601. A first spring 604 is fixed to the inner side of the limiting slider 603. The charging head 103 can charge the battery 201, which is a conventional technical field in the prior art. At the same time, the charging head 103 and the battery 201 are connected to each other. The specific installation method, circuit connection method, and control method of pool 201 are all conventional designs and will not be described in detail here. The bottom of the movable seat 601 is provided with a limit slider 603, which can stably limit the movable seat 601 and ensure that the movable seat 601 can only move laterally inside the working groove 101. When the protective frame 2 is raised, it can push the movable seat 601 to move. At this time, the limit slider 603 at the bottom of the movable seat 601 can squeeze the first spring 604 on one side. When the protective frame 2 stops pushing the movable seat 601, the reaction force of the squeezed first spring 604 can push the movable seat 601 to reset through the limit slider 603.
[0027] The movable seat 601 has a centrally located movable groove 7. A sliding block 701 is slidably connected to one side of the movable groove 7. Connecting brackets 702 are fixed to both ends of one side of the sliding block 701. Clamping blocks 703 are detachably installed on one side of the two connecting brackets 702 via bolts and nuts. A protective sleeve 8 is provided inside the movable groove 7, and the inside of the protective sleeve 8 is filled with electrorheological fluid 801. A second spring 802 is horizontally fixed inside the protective sleeve 8. The clamping block 703 can be disassembled and replaced according to the actual specifications of the automotive parts. When the clamping block 703 contacts the automotive parts, the connecting brackets 702 can push the sliding block 701 to compress the second spring 802. Due to the reaction force of the second spring 802 being squeezed, the sliding block 701 and the connecting frame 702 can push the clamping block 703 to adhere to the outer surface of the automotive parts. When the energized piece 202 on the protective frame 2 contacts the conductive block 602 on the moving seat 601, the electrorheological fluid 801 inside the protective sleeve 8 is energized and can be quickly cured, thus fixing the position of the clamping block 703. When the protective frame 2 moves the energized piece 202 downward, the energized piece 202 cancels the contact with the conductive block 602 and is de-energized. Then the polarization effect between the particles of the electrorheological fluid 801 disappears, and the particles return from an ordered chain structure to a disordered and dispersed state, thereby canceling the fixation of the clamping block 703.
[0028] Example 2 differs from Example 1 mainly in that:
[0029] A safety protection device for processing automotive parts includes a shielding mechanism 4 comprising motors 401 installed inside the left and right sides of the upper surface of a protective frame 2. A take-up roller 402 is installed at the output shaft end of the motor 401. A dustproof film 403 is fixedly connected to the outside of the take-up roller 402. Magnetic strips 5 are fixedly connected to the front and rear ends of the upper surface of the dustproof film 403. When the motor 401 is started, it can drive the take-up roller 402 to rotate. At this time, the take-up roller 402 can perform the work of winding the dustproof film 403.
[0030] Multiple rolls of dustproof film 403 are wound on the take-up roller 402. The magnetic surfaces of the magnetic strips 5 at the left and right ends of the upper surface of the protective frame 2 are magnetically attracted to each other, and the magnetic strips 5 on the left and right sides of the top of the protective frame 2 are magnetically attracted to each other. This allows the dustproof film 403 to cover the top of the protective frame 2, further protecting the automotive parts during processing. At the same time, all contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0031] In this embodiment, the automotive parts to be processed are placed at the center of the working groove 101 on the upper surface of the processing table 1. The servo motor 301 inside the processing table 1 is activated, driving the track shaft 302 to rotate. At this time, the track shaft 302, connected to the track 303, drives another set of similar track shafts 302 to rotate. The two sets of track shafts 302 then drive the threaded rod 304 to rotate within the protective frame 2, which in turn lifts the protective frame 2. During this lifting process, the protective frame 2 can push the movable seat 601 towards the center of the working groove 101. At this time, the clamping block 703 on one side of the movable seat 601 can engage with the working groove 101. The middle automotive parts come into contact, and the second spring 802 is squeezed by the sliding block 701. At the same time, due to the reaction force of the second spring 802 being squeezed, the clamping block 703 can be pushed by the sliding block 701 to fit against the outside of the automotive parts. When the protective frame 2 is raised to the highest position, the energized piece 202 on the protective frame 2 is in contact with the conductive block 602 on one side of the moving seat 601. Then the battery 201 can energize the electrorheological fluid 801 in the moving seat 601. At this time, the electrorheological fluid 801 is energized and solidified, which can complete the position fixation of the protective sleeve 8 and the position fixation of the clamping block 703, so that the clamping block 703 can stably perform the clamping work of the automotive parts.
