Description

Technical Field

[0001] This utility model belongs to the field of finned tube processing technology, specifically relating to a finned tube processing machine tool with a grating safety sensor. Background Technology

[0002] In the field of finned tube processing machine tools, safety protection is of paramount importance, especially during high-speed operation or automated processing, where operators may face the risk of mechanical injury. Existing finned tube processing machine tools typically use fixed protective covers to ensure operational safety.

[0003] Fixed protective covers use metal fences or baffles to isolate dangerous areas. Although the structure is simple, it seriously affects the ease of operation. Especially when frequently changing processed materials or adjusting molds, the protective cover needs to be repeatedly disassembled, reducing production efficiency. Some machine tools are equipped with photoelectric sensors that detect personnel approach through a single beam of infrared light, but the protection range is limited and it is easy to trigger accidental shutdown due to accidental obstruction (such as flying debris). To address this, we have designed a finned tube processing machine tool with a grating safety sensor to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a finned tube processing machine tool with a grating safety sensor to solve the problems mentioned in the background art during the use of the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a finned tube processing machine tool with grating safety sensing, comprising a finned tube machine tool, wherein grating sensing mechanisms are provided at both ends of the finned tube machine tool, the grating sensing mechanism is composed of two symmetrically designed rectangular mounting frames, and a safety grating device is fixed inside the rectangular mounting frame, one of the safety grating devices being a grating generator and the other being a grating receiver.

[0006] Preferably, an L-shaped mounting plate is provided on the outer side of the rectangular mounting bracket, and the L-shaped mounting plate is bolted to the side of the finned tube machine tool.

[0007] Preferably, rectangular mounting plates are fixed at both ends of the top and bottom of the rectangular mounting frame. A transverse bolt is provided inside the rectangular mounting plate. A nut is provided at the end of the L-shaped mounting plate away from the rectangular mounting frame. The nut is located outside the transverse bolt and is threadedly connected to the transverse bolt.

[0008] Preferably, the L-shaped mounting plate has a vertical groove inside, and the horizontal bolt is located inside the vertical groove and is slidably connected to the L-shaped mounting plate through the vertical groove.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention uses two safety light curtains to form a full-coverage light curtain, which can accurately detect intrusions into human body parts such as fingers and palms, avoiding the missed detection problem of traditional single-beam sensors. The safety light curtains are installed inside the L-shaped mounting plate, and the position and height of the safety light curtains can be flexibly adjusted according to different mold heights and processing requirements, eliminating the blind spot problem of traditional fixed protection.

[0017] 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.

[0018] Reference Figure 1-5 A finned tube processing machine tool with grating safety sensing includes a finned tube machine tool 1. Both ends of the finned tube machine tool 1 are equipped with grating sensing mechanisms. The grating sensing mechanism consists of two symmetrically designed rectangular mounting frames 3. A safety grating device 4 is fixed inside the rectangular mounting frame 3. One of the safety grating devices 4 is a grating generator, and the other safety grating device 4 is a grating receiver.

[0019] The grating generator emits infrared or laser beams to form multiple parallel light curtains. The grating receiver detects in real time whether the beams are blocked. If any beam is blocked, the receiver will send a stop signal to the machine tool control system within milliseconds.

[0020] An L-shaped mounting plate 2 is provided on the outside of the rectangular mounting bracket 3. The L-shaped mounting plate 2 is close to the side of the finned tube machine tool 1 and is bolted to the finned tube machine tool 1, so that the rectangular mounting bracket 3 can be installed on the outside of the L-shaped mounting plate 2.

[0021] The rectangular mounting bracket 3 has rectangular mounting plates 5 fixed at both ends of its top and bottom. The rectangular mounting plate 5 has a horizontal bolt 6 inside. The L-shaped mounting plate 2 has a nut 7 at one end away from the rectangular mounting bracket 3. The nut 7 is located outside the horizontal bolt 6 and is threadedly connected to the horizontal bolt 6. Through the threaded connection of the horizontal bolt 6 and the nut 7, the rectangular mounting bracket 3 can be fixed inside the L-shaped mounting plate 2.

[0022] The L-shaped mounting plate 2 has a vertical groove inside. The horizontal bolt 6 is located inside the vertical groove and is slidably connected to the L-shaped mounting plate 2 through the vertical groove. The vertical groove allows the rectangular mounting bracket 3 to be adjusted in position inside the L-shaped mounting plate 2.

[0023] Working principle: The rectangular mounting bracket 3 can be fixed inside the L-shaped mounting plate 2 by the threaded connection of the horizontal bolt 6 and nut 7. The vertical slide groove allows the rectangular mounting bracket 3 to be adjusted in position inside the L-shaped mounting plate 2, so as to adjust the position of the two safety light gratings 4. The light grating generator emits infrared or laser beams to form multiple parallel light curtains. The light grating receiver detects in real time whether the beam is blocked. If any beam of light is blocked, the receiver will send a stop signal to the machine tool control system within milliseconds. When the operator enters the danger zone, the operation of the machine tool can be stopped.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
