Abstract
A kind of safety device of planer belongs to the B27C1/00 class, and it is made up of gland 1, support 2, fixed mount 3.Gland is fixed by bolts on the support, and support is installed on the fixed mount with bolt, and support slides up and down in the fixed mount groove with gland, to adapt to the process wood of different-thickness.The safety apparatus structure is simple, not only is easy to make and install, and also easy to use, safe.
Description
Flat planing machine is to be used for a datum level or two adjacent planar of the work of planing to meet at right angles, and also can be used for adjusting guide plate and add mould planing inclined-plane or curved surface.
Planer is to advance with the hand push workpiece, therefore, does not note very easy having an accident slightly, hinders hand in order to prevent planing tool, and planer must be equipped with safety device.
Present safety device has several:
1, it is to pass the little bamboo clappers of several piece with a stock with tendon rope to constitute.One end of stock is loaded on the left side of front console with spring control, the fan-shaped bamboo clappers cover of the other end of stock cutter shaft makes staff can not contact planing tool, when the planing workpiece, workpiece is pasting the backer and is advancing, making fan-shaped cover open workpiece passes through, after workpiece pushed away the plane mouth, fan-shaped cover was got back to original position again by the strength of spring and is covered on lathe tool.
The shortcoming of this protector:
(1) being through on the bamboo clappers through planing tool long-term cutting with tendon rope will often change;
(2) when to dig thickness be material below 5 centimetres, change the backer and dig inconvenience, do not change the backer and dig that the right finger is dangerous sometimes.
2, automatically controlled brake and energy consumption formula safety device of electric planing machine: this device is avoided with the cutter shaft of promptly stopping and is reduced to dig and hinder accident.Both sides, front and back at cutter shaft are loaded onto the induction copper coin near digging mouth, and are connected with the receiver of control system.The people stands in the emission hands-operation, and electrical apparatus control system has a power relay, and it only just moves under enough big extraneous signal effect and promptly changes unsteady state over to from a stable state.When staff surpassed certain limit with the height of responding to copper coin, the body capacitance oscillation circuit was after transistor amplifies, make the actuating of relay, on the one hand cut off AC power of motor, and be provided with dc source and carry out dynamic braking, in the extremely short time, stop cutter shaft and rotate.Remove when extraneous signal one, circuit itself is got back to original state again, can continue the start planing.
This safety device shortcoming is: because of bring to a halt, cutter shaft will bear very big turning round and refuse, and will be subjected to very big influence the service life of cutter shaft and lathe; But also, make control accuracy also different with the distance of induction copper coin owing to be subjected to influence of various factors such as human body, timber, need the operator often to adjust as the case may be.
3, the strong formula safety device of automatically controlled finger shield.
This device is to cover cutter head with several finger-protectiving keys that are uniformly distributed in cutter shaft, avoids staff to be strayed into the edge of a knife and has an accident.The cambered way of finger-protectiving key is fixed on the table top, and every finger-protectiving key can slide into separately in the arc road and skid off, and plays the effect of protection finger.
The purpose of the invention is a kind of not only safety of design but also without the simple mechanism of control electronics, is not subjected to factor affecting such as artificial and timber, is easy to workman's grasp.
The structural representation of this plane safety device is as shown in Figure 1: it mainly is made up of gland 1, support 2, fixed mount 3, the shape of gland 1 as shown in Figure 2, Fig. 2 a is that front view b is a vertical view, c is a left view.The gland middle part slightly exceeds one deck and is suitable for using hand operated.Left end has two circular holes, with bolt it is fixed on the support 2.
The shape of support 2 is as shown in Figure 3: d is that front view, e are that vertical view, f are left views.Vertical view is rectangular in shape, and two circular holes above it cooperate with two circular holes on the gland, use bolting.Support and gland are fixed together, and slide up and down in the fixed mount groove, to adapt to the process wood of different-thickness.
The planform of fixed mount as shown in Figure 4, g is a front view, h is a vertical view, i is a left view.
Left view is rectangular in shape, and horizontal plane has two circular holes to be installed on the surface planer with bolt, and vertical plane has a chute, and a strip gab is arranged in the chute, and support slides in the chute of fixed mount with gland, with bolt attachment bracket and fixed mount.
Gland 1, support 2, fixed mount 3 usefulness ferrous materials are made, and also available aluminium alloy or timber are made.
The advantage of safety device of electric planing machine: it is simple in structure, is convenient to make and install, and is safe and convenient to use, tries out through the workman to be perfectly safe reliably.
Claims (2)
1, a kind of protection of making the plane lathe, plane safety device particularly, it is made up of gland, support and fixed mount, it is characterized in that: gland 1 is fixed by bolts on the support 2, support 2 usefulness bolts are installed on the fixed mount 3, and fixed mount 3 usefulness bolts are installed on the planer frame; Support 2 slides up and down in fixed mount 3 grooves with gland 1, and support is connected with bolt with fixed mount.
2, plane safety device according to claim 1 is characterized in that, gland 1 support 2, fixed mount 3 usefulness ferrous materials or aluminium alloy are made.
