Abstract
Description
Technical Field
[0001] This utility model relates to the field of drilling technology, specifically to a drilling machine entanglement injury sensor. Background Technology
[0002] In mechanical production, machinery can greatly improve production efficiency, but it can also bring some negative impacts. During operation, improper handling can easily cause accidental injuries to operators. Reducing the occurrence of such injuries is a crucial research direction that many manufacturers urgently need to address. Bench drills are frequently used in factories, and while it is explicitly prohibited to operate them with gloves, some people still disregard this rule. When gloves get tangled in the drill bit, their hands can also be caught in the drill bit, causing serious injury.
[0003] Existing drill bit entanglement injury sensing devices use hand and arm models to simulate the drill bit of a bench drill ensnaring a gloved hand and causing harm to the gloved hand. When the gloved hand model is entangled and pulled into the drill bit, the mounting structure of the hand model is moved, causing impact vibration on the base. This fails to reduce the vibration and impact on the mounting structure of the hand and arm model. Furthermore, when the gloved hand model is entangled and pulled in, the sensing mechanism is also bumped, failing to reduce the impact damage between sensing mechanisms. Moreover, it is inconvenient to disassemble, install, replace, and maintain the sensing mechanism to maintain its sensitivity.
[0004] Therefore, a drill press entanglement injury sensory device is proposed to solve the problems mentioned above. Utility Model Content

[0007] The buffer mounting mechanism includes a mounting plate with a mounting groove in the middle of its top end. An arm model is fixed to the outer end of the hand model and is installed inside the mounting groove. The bottom end of the mounting plate is slidably mounted on the top end of the base.
[0008] Preferably, a sliding groove is formed at the top of the base and at the front side of the bench drill body, and sliding plates are fixed at both ends of the bottom end of the mounting plate. The sliding plates are slidably inserted into the sliding groove. The cross-section of the sliding plates and the sliding groove are both T-shaped structures and are both horizontally arranged.
[0009] Preferably, the mounting plate is a rectangular plate structure and is vertically arranged; the mounting groove is a U-shaped structure and is vertically arranged, with its depth being less than the height of the mounting plate; the arm model is a threaded column structure and is horizontally arranged, with a first nut connected to its surface at a position on both sides of the mounting groove.
[0010] Preferably, an installation rod is fixed in the middle of the sliding groove, a first spring is slidably sleeved on the inner end surface of the installation rod, a guide hole is opened in the middle of the surface of the sliding plate, and the installation rod slides through the guide hole.
[0011] Preferably, the inner end of the first spring is connected to the inner end of the sliding groove, the mounting rod is a threaded rod structure and is horizontally arranged, with its outer end protruding from the outer end of the sliding groove, and a limiting plate is slidably sleeved on the surface of the mounting rod at a position outside the base, and a second nut is connected to the surface of the mounting rod at a position outside the limiting plate.
[0012] Preferably, the sensing mechanism includes a first photoelectric sensor and a second photoelectric sensor. The top of the base has a first connecting hole, which is a threaded hole structure and is vertically arranged directly below the palm model. A first connecting rod is threaded into the first connecting hole. The first connecting rod is a threaded rod structure and is vertically arranged. The first photoelectric sensor is fixedly installed on the top of the first connecting rod.
[0013] Preferably, a second connecting hole is formed on the side and bottom of the mounting plate, directly below the mounting groove. A second connecting rod slides through the second connecting hole. The second connecting rod is a threaded rod structure, and a third nut is connected to its surface outside the second connecting hole. The second photoelectric sensor is fixed to the inner end of the second connecting rod. A second spring is sleeved on the surface of the second connecting rod between the second photoelectric sensor and the side of the mounting plate. The second photoelectric sensor and the first photoelectric sensor are horizontally aligned. A controller is installed on the side of the base.
[0014] Compared with the prior art, this utility model provides a somatosensory device for detecting drill press entanglement injuries, which has the following beneficial effects:
[0015] 1. A sliding groove is provided at the top of the base, and an installation rod and a second spring are provided inside the sliding groove. Therefore, the mounting plate is slidably attached to the top of the sliding groove through the sliding plate. When the gloved hand model is wrapped around and rolled into the drill bit of the bench drill, the mounting plate moves along the sliding groove toward the main body of the bench drill. The first spring cushions the impact between the sliding plate and the inner end of the sliding groove, reducing vibration.
[0016] 2. The arm model is fixed to the outer end of the palm model and installed on the side of the mounting plate by the first nut and the mounting groove. The height of the palm model and the arm model can be adjusted along the mounting groove to adjust the position between the gloved palm model and the drill bit of the bench drill body. In addition, it is easy to disassemble and replace the palm model and the arm model.
[0017] 3. A first photoelectric sensor is detachably mounted on the front side of the bench drill body via a first connecting rod, and a second photoelectric sensor is detachably mounted on the side of the mounting plate via a second connecting rod. Furthermore, the inner side of the second photoelectric sensor is elastically buffered to the mounting plate via a second spring. Therefore, when a gloved hand model is wrapped around and caught in the drill bit of the bench drill body, the mounting plate moves along the sliding groove and drives the second photoelectric sensor to move, so that the second photoelectric sensor and the first photoelectric sensor make mutual buffered contact, reducing impact damage and facilitating disassembly and replacement. Thus, the bench drill body can be stopped from rotating by the controller, making it easy for external observers to observe the danger of a gloved hand being caught in the bench drill body.

[0027] The buffer mounting mechanism includes a mounting plate 8, with a mounting groove 16 in the middle of the top of the mounting plate 8. An arm model 5 is fixed to the outer end of the hand model 4, and the arm model 5 is installed inside the mounting groove 16.

[0030] This allows for easy adjustment of the position between the gloved hand model 4 and the drill bit of the bench drill body 3, enabling flexible winding simulation. Furthermore, it facilitates the disassembly and replacement of the hand model 4 and the arm model 5.
[0031] In detail, a sliding groove 7 is opened at the top of the base 1 and at the front side of the bench drill body 3. Sliding plates 19 are fixed at both ends of the bottom of the mounting plate 8. The sliding plates 19 slide into the sliding groove 7. The cross-section of the sliding plates 19 and the sliding groove 7 are both T-shaped structures and are both horizontally set.
[0032] An installation rod 11 is fixed in the middle of the sliding groove 7. A first spring 17 is slidably sleeved on the inner end surface of the installation rod 11. A guide hole 20 is opened in the middle of the surface of the sliding plate 19. The installation rod 11 slides through the guide hole 20.
[0033] The inner end of the first spring 17 is connected to the inner end of the sliding groove 7. The mounting rod 11 is a threaded rod structure and is set horizontally, with its outer end protruding from the outer end of the sliding groove 7.
[0034] The mounting rod 11 is slidably fitted with a limiting plate 9 at a position outside the base 1, and a second nut 12 is connected to the mounting rod 11 at a position outside the limiting plate 9.
[0035] A sliding groove 7 is provided at the top of the base 1, and an installation rod 11 and a first spring 17 are provided inside the sliding groove 7. Therefore, the mounting plate 8 is slidably snapped onto the top of the sliding groove 7 via the sliding plate 19.
[0036] When the gloved hand model 4 is wrapped around the drill bit of the bench drill body 3, the mounting plate 8 moves along the sliding groove 7 toward the bench drill body 3, and the first spring 17 cushions the impact between the sliding plate 19 and the inner end of the sliding groove 7, reducing vibration.
[0037] Finally, the sensing mechanism includes a first photoelectric sensor 6 and a second photoelectric sensor 23. The top of the base 1 has a first connecting hole 18, which is a threaded hole structure and is vertically positioned directly below the palm model 4.

Furthermore, the inner side of the second photoelectric sensor 23 is elastically buffered to the mounting plate 8 via the second spring 22.
[0043] Therefore, when the gloved hand model 4 is wrapped around the drill bit of the bench drill body 3, the mounting plate 8 moves along the sliding groove 7 and drives the second photoelectric sensor 23 to move, so that the second photoelectric sensor 23 and the first photoelectric sensor 6 make mutual buffer contact, reducing impact damage and making it easy to disassemble and replace.
[0044] The controller 10 stops the rotation of the bench drill body 3, making it easier for external observers to observe the danger of the gloved hand model 4 being caught in the bench drill body 3.
