Description

Cutting machine safety cover interlocking structure

本实用新型是关于一种安全护罩连动结构，特别是一种可达到准确、及时掀启护罩，以有助于操作者工作的进行及切实保护使用者安全功效的防护罩连动结构。The utility model relates to a linkage structure of a safety shield, in particular to a linkage structure of a shield that can be opened accurately and in time to facilitate the operator's work and effectively protect the user's safety. .

一般切断机的组成，如图1所示。在机体1一端设有支臂10，该支臂上设一锯座11，其上装有锯片12，锯片12外套有护罩13。连动片14一端以转轴与支臂10构接，另一端开有滑槽15，以偏心销16连接滑槽15与护罩13。使用者向下按压锯座11护罩13自动在滑槽15与偏心销16作用下向上掀开，露出锯片，即可开始使用。The composition of the general cutting machine is shown in Figure 1. One end of the body 1 is provided with a support arm 10, on which a saw stand 11 is arranged, on which a saw blade 12 is housed, and the saw blade 12 is covered with a shield 13. One end of the connecting plate 14 is connected with the support arm 10 by a rotating shaft, and the other end is provided with a slide groove 15 , and the slide groove 15 and the shield 13 are connected with the eccentric pin 16 . The user presses down the saw base 11 and the shield 13 is automatically lifted upwards under the action of the chute 15 and the eccentric pin 16 to expose the saw blade, and the saw blade can be started to use.

以上结构由于连动片14的滑槽15与偏心销16的相对连动系为直线轨迹，而偏心销16拉引护罩13的轨迹为孤形轨迹，因此该护罩13的掀合常有迟滞及不顺畅情况，亦即不能精确及时动作，掀启角度不够精确，而造成护罩13定向性不足容易卡到工作物的情形，这种常用连动结构未尽理想，极待进一步改良。In the above structure, the relative interlocking system between the chute 15 of the link plate 14 and the eccentric pin 16 is a straight track, and the track of the eccentric pin 16 pulling the guard 13 is an arc track, so the flipping of the guard 13 often has Hysteresis and unsmooth conditions, that is, inability to move accurately and in time, and the opening angle is not accurate enough, resulting in the lack of orientation of the shield 13 and the situation that it is easy to get stuck on the work object. This commonly used interlocking structure is not ideal and needs further improvement.

有鉴于上述提常用切断机安全护罩连动结构之缺陷，实用新型发明人以积多年的制造及使用经验，再经详细思索，并考察实际使用状况，几经试验，提出本实用新型的安全护罩连动结构。In view of the defects of the interlocking structure of the safety guard of the commonly used cutting machine mentioned above, the inventor of the utility model has accumulated many years of manufacturing and use experience, and after careful consideration and investigation of the actual use conditions, after several tests, the utility model proposes the safety guard of the present utility model. Cover linkage structure.

本实用新型的主要目的，即在提供一种安全护罩连动结构，其利用滑杆在槽块上随锯座的作动而位移，并同步拉引护罩掀启，使护罩可达到精确定向之目的，以提供最佳使用及保护效果。The main purpose of this utility model is to provide a safety guard interlocking structure, which uses a slide bar to move on the slot block with the movement of the saw seat, and simultaneously pulls the guard to open, so that the guard can reach The purpose of precise orientation, in order to provide the best use and protection effect.

本实用新型的连接结构系由一连接片、一槽块及一滑杆所构成。其中连接片一端锁固在机体侧所设的支臂上，而槽块一端与连接片的另一端枢设结合，两侧制作内折状翼部，使中间形成一滑动空间，而另一端固设在护罩上，并与护、锯座之枢合处偏心对应。The connecting structure of the utility model is composed of a connecting piece, a groove block and a slide bar. One end of the connecting piece is locked on the support arm provided on the side of the machine body, and one end of the groove block is pivotally combined with the other end of the connecting piece, and folded wings are made on both sides to form a sliding space in the middle, while the other end is fixed. It is located on the guard and corresponds to the eccentricity of the hinge of the guard and the saw seat.

按图2、图3所示，切断机机体5一端的支臂50上组设一锯座6，而锯座6上一端设有锯片60，并以一护罩7套住使锯片60不致突兀露出。本实用新型结构是由一连接片2、一槽块3及一滑杆4所构成，其中，连接片2一端锁固在机体5上一侧所设的支臂50上，且连接片2适当位置开设有一位移孔20，并在该位移孔2上枢设轴销21。As shown in Fig. 2 and Fig. 3, a saw base 6 is set on the support arm 50 at one end of the cutting machine body 5, and a saw blade 60 is arranged at one end of the saw base 6, and a guard 7 is used to cover the saw blade 60. Not to be exposed abruptly. The structure of the utility model is composed of a connecting piece 2, a groove block 3 and a slide bar 4, wherein one end of the connecting piece 2 is locked on the support arm 50 provided on the upper side of the body 5, and the connecting piece 2 is properly A displacement hole 20 is defined at the position, and a shaft pin 21 is pivotally arranged on the displacement hole 2 .

该槽块3的一端与连接片2的另一端枢设结合，其两侧制作内折状的翼部30，使中间处形成为滑动空间31，至于滑杆4，是穿设在该滑动空间31中，一端折制有卡制部40，而另一端则固设在护罩7上，并与护罩7、锯座6的枢合处70偏心对应。One end of the groove block 3 is pivotally combined with the other end of the connecting piece 2, and the two sides are made with folded wings 30 to form a sliding space 31 in the middle. As for the sliding bar 4, it is passed through the sliding space. 31 , one end is folded with a clamping portion 40 , while the other end is fixed on the shield 7 and corresponds to the pivot joint 70 of the shield 7 and the saw base 6 eccentrically.

按图3～图5所示，当使用者按压锯座6使其向下位移时，该滑杆4随之向下位移，并促使槽块3转动，此时，由于该锯座6以支臂50上的枢合处51为轴点转动，所以滑杆4随槽块3转动而转动，此时，在不同轴点及不同半径的作用下，该滑杆4相对槽块3产生了适当的滑移，而且对安全护罩7形成了拉引作用，使其得以向上掀启，达到露出锯片60的目的。As shown in Figures 3 to 5, when the user presses the saw base 6 to make it move downward, the slide bar 4 moves downward accordingly, and prompts the groove block 3 to rotate. The pivot point 51 on the arm 50 rotates as a pivot point, so the slide bar 4 rotates with the rotation of the slot block 3. At this time, under the action of different pivot points and different radii, the slide bar 4 produces a rotation relative to the slot block 3. Appropriate sliding also forms a pulling effect on the safety cover 7 so that it can be opened upwards to expose the saw blade 60 .

由于滑杆4卡制在槽块3所形成之滑动空间31内，而且则面有又翼部30做为止挡，所以在滑动的过程中，滑杆4并不致产生滑脱现象，因此，本实用新型之实用性毋庸置疑。Since the slide bar 4 is clamped in the sliding space 31 formed by the groove block 3, and there are wings 30 on the surface as stoppers, the slide bar 4 will not slip during the sliding process. Therefore, the utility model The practicality of the new model is beyond doubt.

此外滑杆4滑移的同时，该槽块3亦同步转动，故滑杆4不但摆动顺畅，而且其拉动护罩7的动作也相当平顺，因此自可促使护罩7及时掀起，换句话说，该护罩7的定向性良好，不致有误开的情形，如此对使用者而言，即是具有较佳的保护效果。In addition, when the slide bar 4 slides, the groove block 3 also rotates synchronously, so the slide bar 4 not only swings smoothly, but also pulls the shield 7 smoothly, so that the shield 7 can be lifted up in time, in other words , the orientation of the protective cover 7 is good, and there is no situation that it will be opened by mistake, so it has a better protective effect for the user.

另，按图3～5所示，使用者可于该连动结构组装后，随实际的使用情况适当调整该连接片20与轴销21之相互位置，此时该槽块3与该滑杆4也随之产生微量位移的效果，换句话说，经由连接片20与轴销21的调整，相对应连动结构作动产生微调功效，致使护罩7的开启作动更符合实际工作的要求，其实用性可再次获得证明。In addition, as shown in Figures 3-5, the user can properly adjust the mutual position of the connecting piece 20 and the shaft pin 21 according to the actual use after the linkage structure is assembled. At this time, the groove block 3 and the slide bar 4 also produces the effect of micro-displacement, in other words, through the adjustment of the connecting piece 20 and the pivot pin 21, the action of the corresponding linkage structure produces a fine-tuning effect, so that the opening action of the shield 7 is more in line with the actual work requirements , its practicability can be proved again.
