Description

Technical Field

[0001] This application belongs to the field of safety engineering, and specifically relates to a safety protection device for a bench lathe. Background Technology

[0002] A bench lathe is a small, fixed metal cutting machine tool mainly used for rotary machining of metal (such as steel, iron, copper, aluminum, etc.) or other hard materials. Through the relative movement of the cutting tool and the rotating workpiece, the workpiece is cut and shaped. It is one of the most basic and commonly used equipment in the field of machining, and is widely used in small factories, repair shops, laboratories and personal workshops.

[0003] Most safety guards for benchtop lathes currently on the market use fixed-structure baffle designs, which can only cover the machining area of ​​specific lathe sizes. When dealing with workpieces of different sizes or changing lathe models, the guards cannot be flexibly adapted, resulting in insufficient protection and the risk of metal fragments flying. Some adjustable guards have low adjustment precision and poor stability, and are prone to displacement under the vibration generated by the high-speed operation of the lathe, reducing the protective effect. At the same time, existing devices have limited functions, only providing basic shielding and lacking specialized protective designs for different machining scenarios. Users need to purchase various additional protective accessories, increasing equipment adaptation costs and operational complexity, and failing to fully avoid the risk of safety accidents. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, this application provides a safety protection device for a bench lathe. Through the coordinated design of a main baffle assembly, a limiting installation mechanism, and a secondary baffle assembly, the main baffle assembly serves as the basic protective structure. The limiting installation mechanism enables precise adjustment and stable fixation. The secondary baffle assembly, through rotational opening and closing and the combination of its upper and lower surfaces, covers the lathe's machining area and is adaptable to different specifications of bench lathes and machining scenarios. The main baffle assembly is fixed to the lathe worktable via a mounting base. The guide groove and the adjusting rod of the limiting installation mechanism slide together, allowing for position adjustment in both vertical and horizontal directions. The adjusting rod, screw, and adjusting knob work together to precisely control the tightness and movement distance of the main and secondary baffles, ensuring stability even under lathe vibration. The secondary baffle assembly achieves rotational opening and closing via a rotating hinge, facilitating workpiece clamping and machining observation. The upper and lower surfaces of the secondary baffle can be freely combined according to the machining depth, covering the entire area from the top of the workpiece to the lathe guide rail, preventing metal debris from flying. In addition, the rubber buffer pad at the bottom of the mounting base reduces vibration transmission, the fitting structure of the limiting interlocking block and the limiting fixing hole improves the fixing stability, and the combination of multi-layer baffles and flexible adjustment structure not only meets the protection needs of different processing scenarios, but also reduces equipment adaptation costs and reduces the risk of safety accidents.

The limiting fixing hole and the limiting fitting block fit together to ensure adjustment accuracy and meet the protection needs of workpieces of different widths. The screw of the adjusting frame and the adjusting knob work together to drive the secondary baffle assembly to rise and fall vertically, adapting to workpieces of different heights and solving the problem of poor adaptability of existing devices. The secondary baffle assembly achieves rotational opening and closing through a rotating hinge, facilitating workpiece clamping and processing observation. The upper and lower plates can be extended and combined to cover the entire area from the top of the workpiece to the lathe guide rail, blocking metal debris from flying. At the same time, the inner sound insulation cotton absorbs some noise, improving the operating environment. The rubber buffer pad of the mounting base reduces vibration transmission. The fixing hole is compatible with most lathe worktables, and the bolt fixing ensures structural stability and avoids vibration displacement. This achieves a multi-functional protection method to cope with various processing scenarios such as deep hole processing and end face cutting, reducing the types of protective accessories required by users and operating units, thereby reducing equipment adaptation costs and comprehensively avoiding the safety risks caused by flying metal debris.

[0018] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0020] In some embodiments, please refer to Figures 1 to 4 This application provides a safety protection device for a bench lathe, comprising: a main baffle assembly 100, a limiting installation mechanism 200, and a secondary baffle assembly 300. The main baffle assembly 100 is fixed to the bench lathe worktable via a mounting base 103. The limiting installation mechanism 200 is disposed inside the main baffle assembly 100. The secondary baffle assembly 300 is connected to the main baffle assembly 100 via the limiting installation mechanism 200, thereby realizing position adjustment and protection functions.

[0021] In this embodiment, a rubber buffer pad is attached to the bottom of the mounting base 103. A fixing hole is provided on the outer side of the mounting base 103. During use, bolts are passed through the fixing hole and threaded into the threaded hole of the bench lathe worktable to firmly fix the main baffle assembly 100 onto the worktable. The buffer pad reduces the transmission of lathe vibration to the main baffle assembly 100, preventing the device from loosening or shifting. The main baffle plate surface 101 on the outer side of the main baffle assembly 100 initially blocks metal debris. The inner guide groove 102 provides a sliding track for the adjusting rod 201 of the limiting mounting mechanism 200. One end of the adjusting rod 201 passes through the main baffle assembly 100 and is slidably connected to the guide groove 102; the other end is fixed to the connecting seat 202, which is connected to the secondary baffle assembly 300. Pushing the adjusting rod 201 can cause the secondary baffle assembly 300 to move horizontally along the guide groove 102, adapting to workpieces of different widths. The limiting fitting block 203 on the inner side of the connecting seat 202 engages with the limiting fixing hole 104 of the main baffle assembly 100, which can fix the secondary baffle assembly 300 in the adjusted horizontal position to ensure stability.

[0022] In some embodiments, an adjustment bracket 204 is fixed to the outside of the connecting seat 202 of the limiting installation mechanism 200. The inner side of the adjustment bracket 204 is provided with a threaded structure. The screw 206 passes through the threaded structure and one end is rotatably connected to the auxiliary baffle connecting block 205. The other end is fixed with an adjustment knob 207. The outer side of the adjustment knob 207 has anti-slip texture.

[0023] In this embodiment, when the height of the secondary baffle assembly 300 needs to be adjusted, the user rotates the adjustment knob 207, causing the screw 206 to rotate. Because the screw 206 engages with the threaded structure of the adjustment bracket 204, the screw 206 moves axially, thereby pushing or pulling the secondary baffle connecting block 205. The secondary baffle connecting block 205 is fixedly connected to the secondary baffle assembly 300, thus causing the secondary baffle assembly 300 to rise and fall vertically, adapting to the processing needs of workpieces of different heights. The anti-slip texture prevents slippage when rotating the adjustment knob 207, making adjustment more effortless and precise.

[0024] In some embodiments, the sub-baffle assembly 300 includes a lower sub-baffle surface 301 and an upper sub-baffle surface 302. The lower sub-baffle surface 301 is connected to the limiting installation mechanism 200 via a sub-baffle connecting block 205. The upper sub-baffle surface 302 is disposed outside the lower sub-baffle surface 301. There is a sub-baffle connecting point 303 at the junction of the two. A rotating hinge 304 is provided between the sub-baffle connecting block 205 and the lower sub-baffle surface 301.

[0025] In this embodiment, the upper surface 302 of the secondary baffle can extend and retract relative to the lower surface 301 of the secondary baffle along the connection 303. The combined protective height is adjusted according to the workpiece machining depth to ensure coverage of the area from the top of the workpiece to the lathe guide rail. When it is necessary to clamp the workpiece or observe the machining process, the secondary baffle assembly 300 can be rotated outward around the pivot hinge 304 to open, and then rotated back to close after the operation is completed. This facilitates operation and effectively prevents metal debris from flying.

[0026] Working principle: First, the mounting base 103 at the bottom of the main baffle assembly 100 is attached to the preset installation position on the worktable of the bench lathe. Ensure that the fixing holes on the outer side of the mounting base 103 are precisely aligned with the threaded holes on the surface of the worktable, and that the mounting base 103 is stably connected to the worktable. At this time, the rubber buffer pad attached to the bottom of the mounting base 103 is tightly attached to the worktable surface, which can initially reduce the transmission of vibrations generated during subsequent lathe operation. According to the width of the workpiece to be processed, the adjusting rod 201 on the outer side of the limiting installation mechanism 200 is pushed. Since one end of the adjusting rod 201 passes through the main baffle assembly 100 and is slidably connected to the guide groove 102 on the inner side of the main baffle assembly 100, the adjusting rod 201 will smoothly move along the horizontal direction of the guide groove 102. The movement simultaneously drives the connecting seat 202, which is fixed to the other end of the adjusting rod 201, and the secondary baffle assembly 300 connected to the connecting seat 202 to move horizontally. When the secondary baffle assembly 300 moves to a suitable position that can cover the horizontal processing area of ​​the workpiece, the adjustment rod 201 is stopped, and then the limiting fitting block 203 on the inner side of the connecting seat 202 is pressed to make it embed into the corresponding limiting fixing hole 104 on the outer side of the main baffle assembly 100, thus completing the fixation of the horizontal position of the secondary baffle assembly 300. To adjust the height, simply rotate the adjusting knob 207 at one end of the adjusting frame 204 in the limiting installation mechanism 200 according to the height of the workpiece to be processed. Since the adjusting knob 207 is fixedly connected to the screw 206, and the screw 206 passes through the adjusting frame 204, the adjustment knob 207 is fixedly connected to the screw 206. The threaded structure on the inner side of 04, under the action of thread engagement, causes the screw 206 to move axially along the adjusting bracket 204. Since one end of the screw 206 is rotatably connected to the auxiliary baffle connecting block 205, the axial movement of the screw 206 will push or pull the auxiliary baffle connecting block 205, thereby causing the auxiliary baffle assembly 300, which is fixedly connected to the auxiliary baffle connecting block 205, to rise and fall vertically. When the auxiliary baffle assembly 300 rises and falls to a height that can cover the vertical processing area of ​​the workpiece, stop rotating the adjusting knob 207, and the vertical height of the auxiliary baffle assembly 300 is fixed. Auxiliary baffle extension and retraction adjustment: According to the processing depth requirements of the workpiece, pinch the edge of the upper plate surface 302 of the auxiliary baffle assembly 300 by hand, and move along the lower plate surface 301 of the auxiliary baffle and the auxiliary baffle... At the junction of the upper and lower plates 302, pull the upper plate 302 of the sub-baffle upwards or downwards to adjust the relative extension length of the upper and lower plates 301 until the combined protective height can completely cover the machining area from the top of the workpiece to the lathe guide rail. Then release the upper plate 302, which will maintain its current extension state under its own structural limit. The workpiece clamping and protection are activated. Hold the outer edge of the lower plate 301 of the sub-baffle assembly 300 and rotate the sub-baffle assembly 300 outwards around the pivot hinge 304 at the connection point between the sub-baffle connecting block 205 and the lower plate 301, so that sufficient space is formed between the sub-baffle assembly 300 and the main baffle assembly 100.The auxiliary baffle assembly 300 is designed to facilitate the operator in clamping the workpiece onto the lathe chuck or fixture. After the workpiece is securely clamped, the auxiliary baffle assembly 300 is rotated in the reverse direction until it returns to its initial protective position, forming a closed processing protection area together with the main baffle assembly 100. During processing, the outer surface 101 of the main baffle assembly 100 initially blocks flying metal debris, while the lower surface 301 and upper surface 302 of the auxiliary baffle assembly 300 further block debris flying from different directions, preventing debris from escaping the protection area.
