Description

[Detailed description of the invention] [Industrial application field] The invention can be applied to, for example, a square chisel machine, a chain chisel machine,
Related to vise devices for wood processing machines, such as patterning machines.

[Conventional technology]

Conventionally, known vise devices for this type of wood processing machine include one in which a non-slip device is provided on the bed of a flat vise, and one in which a workpiece is clamped using a chain. (Refer to Utility Model Publication No. 56-14977 and Utility Model Publication No. 60-12695) [Problem to be solved by the invention] In conventional vise devices, irregularly shaped workpieces such as logs are connected between the ink line and the core of the processing machine body. There was a problem in that it was difficult to fix the device in a state in which it was released.

The present invention was developed in view of these problems with the conventional technology, and its purpose is to maintain the centering of the ink line and the processing machine body when processing irregularly shaped workpieces such as logs. The present invention aims to provide a vise device for a wood processing machine that can be firmly fixed.

[Means to solve problems]

In order to achieve the above object, the vise device of the wood processing machine according to the present invention is provided with a bed at both front and rear ends of a pair of left and right front and rear guide bars which are covered with the main body of the processing machine so as to be slidable in the front and rear directions, In addition to providing adjustment screws each having a non-slip function, one end is connected to a chain vise part provided at one end in the left and right direction of the bed, and the free end is freely hooked and removed from a claw part provided at the other end. The workpiece clamping chain itself or a non-slip mechanism is provided between the chain and the workpiece.

[Effect]

Set the bed of the vise device on the workpiece, align the center mark of the bed with the ink line, adjust the longitudinal direction of the workpiece and the vertical extension of the processing machine body using the adjustment screw in the center, and adjust the diameter of the workpiece. After adjusting the direction and vertical alignment of the processing machine body using the other adjustment screw, hook the free end of the chain to the claw, then screw the vise screw with the vise handle, tension the chain, and the above adjustment screws will tighten. The workpiece can be firmly tightened without slipping or the like by the anti-slip provided therein, the chain, or the anti-slip provided between the chain and the workpiece.

In this state, operate the feed handle on the processing machine main body and lower the processing machine main body to process the workpiece with the cutter part, but to prevent the workpiece from slipping, process with the adjustment as described above. The machine body can be securely fixed to the machine to be machined, and processing can be performed accurately along the ink lines.

Both ends of the front and rear guide bars 1, 1' are fixed to beds 9, 9', and on both front and rear sides of the beds 9, 9' there is a center mark indicating the movement line a of the cutter part 5 in the processing machine main body 2. A mark 11 is provided.
Further, an adjustment screw 12 having a spike-shaped anti-slip 12a at the tip is screwed through the bets 9, 9' so as to be adjustable in the axial direction, in alignment with the movement line a of the cutter part 5. Bet 9,
On the left and right sides of 9', there are spike-shaped anti-slip 1 on the tip.
Adjustment screws 13 and 14 having 3a and 14a are screwed through the workpiece 15 so that they can be adjusted forward and backward in the axial direction at a predetermined angle so as to face the center O of the workpiece 15.

A chain vise portion 16 is provided at one end in the left-right direction of the beds 9, 9', and a claw portion 17 is provided at the other end.

The chain vise part 16 includes a rotatable horizontal shaft 18, a vise screw 19 that rotatably passes through the horizontal shaft 18 while being prevented from moving in the axial direction, and a collar 20 interposed at the outer end of the vise screw 19. The vise handle 21 fixed by
9, and a chain pull nut 22 which is screwed into the screw portion 19a of No. 9 so that it can move forward and backward, and one end of a chain 23 for clamping the workpiece is connected to the chain pull nut 22.

At the free end of the chain 23, chain pins 23a, which are formed by extending link pins of the chain 23, are selectively and detachably latched to the claw portion 17 in accordance with the dimensions of the workpiece 15. It is designed so that

Further, the chain 23 itself or between the chain 23 and the workpiece 15 is provided with anti-slip devices 24, 2.
4' is provided, and the chain 23 and the anti-slip 2
4 and 24' to clamp the workpiece 15.

Further, as shown in the illustrated example, vice arms 25, 25', which are separate members, are pivotally attached to both the left and right ends of the beds 9, 9', and the claw portion 17 is attached to one of the vice arms 25.
The chain vise portions 16 are provided on the other vise arm 25', and the anti-slip portions 24, 2
4' may be provided on the inner surface of the lower end of each vice arm 25, 25'.

In addition, in Fig. 1, 26, 26' are stands,
Reference numerals 27 and 27' indicate coil springs that rotate and bias the vise arms 25 and 25' upward, respectively. In FIG. 2, 28 and 28' indicate handles.

In Fig. 3 A and B, 29 indicates a black line drawn on the log as the workpiece 15, and in Fig. 3A, Fig. 4, Fig. 5, and Fig. Each hole is shown.

[Effect of idea]

Since the present invention is constructed as described above,
When clamping the workpiece 15, the workpiece 1
