DISPOSITIVO PARA CUBRIR LA BROCA Y MANDRIL, SU PROCESO DE DEVICE FOR COVERING THE BROCA AND MANDRIL, ITS PROCESS OF
ENSAMBLE Y ELABORACION ASSEMBLY AND PREPARATION
Sector tecnológico: Technology Sector:
Ingeniería mecánica. Problema técnico: Mechanical Engineering. Technical problem:
Los mandriles y brocas en los taladros son utilizados, en la mayoría de los casos, sin protección alguna del usuario; esto conlleva a un alto riesgo de lesiones físicas causadas por el contacto de la broca en movimiento y el operador. Este riesgo aumenta si se tiene en cuenta que dichas herramientas no siempre son utilizadas por personas idóneas para el manejo de estos, tales como aficionados del arreglo y en algunos casos niños. Chucks and drills in drills are used, in most cases, without any user protection; This leads to a high risk of physical injury caused by the contact of the moving bit and the operator. This risk increases if one takes into account that these tools are not always used by people suitable for handling them, such as fans of the arrangement and in some cases children.
Prácticas inadecuadas en el uso del taladro como trasladarlo con las brocas puestas o la mala sujeción de estas puede llevar a que el taladro se caiga y cause daños tanto en la broca como en el área de trabajo. Inappropriate practices in the use of the drill, such as transferring it with the drills in place or the bad grip of these, can lead to the drill falling and causing damage to both the drill and the work area.
Descripción de la invención. Description of the invention
El dispositivo para cubrir la broca y el mandril tiene como fin brindar protección al operario frente a los riesgos anteriormente mencionados por la broca en rotación; facilitar el manejo del taladro y recoger el polvo producido por su uso. Todo esto, sin afectar la libre rotación del mandril. The device for covering the drill and the mandrel is intended to provide protection to the operator against the risks mentioned above by the rotating drill; facilitate the handling of the drill and collect the dust produced by its use. All this, without affecting the free rotation of the mandrel.
El dispositivo que recubre la broca se instala sobre el mandril de manera fácil y rápida y se contrae a medida que la broca penetra la superficie. Este consiste en tres tubos superpuestos: el tubo de acople, el tubo conector y el tubo deslizante.
El tubo de acople (1) se instala sobre el mandril y se puede sujetar por abrazadera de presión (16); si está elaborado en material rígido tendrá cortes transversales que le permiten reducir el diámetro para lograr sujeción. Además, este tubo tiene un canal (2) donde se instala un medidor de longitud de penetración de la broca, esta medida se fija con una tuerca de fijación(17), el tubo de acople (1) y el tubo conector (3) se unen entre sí por enroscado, este sistema de enroscado ayuda a dar el largo necesario según el largor de la broca. El tubo conector (3) tiene unos canales (6) en bajo relieve sobre su superficie que le permiten a la guía (15) del tubo deslizante (11) acoplarse con el canal de entrada, hacer movimientos retráctiles por los canales horizontales (6) y asegurarse por los canales verticales (5). Este tubo contiene en su interior un pasador resorte (7) el cual asoma su cabeza por los agujeros (8) que tiene el tubo conector (3) y el tubo deslizante (11), esto asegura al tubo deslizante (11) y que al liberarlo con solo se adelante por sí solo, esto gracias a la acción del resorte (10) de compresión que está contenido dentro del tubo deslizante(l l) y que se apoya sobre la base cónica en la cabeza del tubo conector (3) . El tubo deslizante (11) aparte de tener la guía de desplazamiento interna y los agujeros de paso (8) para el pasador resorte (10), tiene un soporte de apoyo para el operario (12). The device that covers the drill is installed on the mandrel easily and quickly and contracts as the drill penetrates the surface. This consists of three overlapping tubes: the coupling tube, the connecting tube and the sliding tube. The coupling tube (1) is installed on the mandrel and can be held by a pressure clamp (16); if it is made of rigid material, it will have transversal cuts that allow it to reduce the diameter to achieve support. In addition, this tube has a channel (2) where a drill penetration length meter is installed, this measurement is fixed with a fixing nut (17), the coupling tube (1) and the connecting tube (3) they are joined together by screwing, this screwing system helps to give the necessary length according to the length of the drill. The connector tube (3) has channels (6) in low relief on its surface that allow the guide (15) of the sliding tube (11) to engage with the inlet channel, make retractable movements through the horizontal channels (6) and secure by vertical channels (5). This tube contains inside a spring pin (7) which sticks its head through the holes (8) that has the connecting tube (3) and the sliding tube (11), this ensures the sliding tube (11) and that release it with just forward on its own, this thanks to the action of the compression spring (10) that is contained within the sliding tube (ll) and that rests on the conical base on the head of the connector tube (3). The sliding tube (11) apart from having the internal displacement guide and the passage holes (8) for the spring pin (10), has a support support for the operator (12).
Este dispositivo permite almacenar el polvo proveniente de la penetración de la broca en el interior del tubo deslizante (1 1) y se vacía con solo retirar el tubo deslizante. This device allows the dust from the penetration of the drill into the sliding tube (1 1) to be stored and emptied by simply removing the sliding tube.
El tubo deslizante (11) al tener una base sobre el extremo que se une con la superficie a taladrar mejora la estabilidad del taladro y evita movimientos inseguros del mismo, además la base puede estar cubierta por materiales suaves que evitan dañar los contornos de la superficie a taladrar.
Este dispositivo se puede ensamblar in situ, este proceso consiste en insertar el resorte de compresión (10) al tubo deslizante (11), posteriormente acoplar la guía (15) del tubo deslizante al canal de entrada (4) del tubo conector(3), luego se inserta el pasador resorte (7) al interior del tubo conector (3) para anclar en agujeros de paso (8), se enrosca el tubo conector (3) al tubo de acople (1) y finalmente se pone sobre este último la tuerca de fijación (17) y la abrazadera (16). Los elementos que componen este dispositivo se pueden elaborar en plástico o en metal por inyección en moldes. The sliding tube (11) by having a base on the end that joins the surface to be drilled improves the stability of the drill and prevents unsafe movements of the same, in addition the base can be covered by soft materials that avoid damaging the contours of the surface to drill This device can be assembled on site, this process consists of inserting the compression spring (10) to the sliding tube (11), then coupling the guide (15) of the sliding tube to the inlet channel (4) of the connecting tube (3) , then the spring pin (7) is inserted into the connector tube (3) to anchor in through holes (8), the connector tube (3) is screwed to the coupling tube (1) and finally placed on the latter the fixing nut (17) and the clamp (16). The elements that make up this device can be made of plastic or metal by injection into molds.
