Abstract

PURPOSE:To obtain a clamping device which is small-sized and has good mechanical strength and accuracy by connecting an inlet side clamp and an outlet side clamp and providing a clamping mechanism for cross adjustment separately from the inlet side clamp. CONSTITUTION:A preceding plate 6 and a succeeding plate 5 are clamped by an inlet side clamp 1 and an outlet side clamp 2. The clamped plate 6 and plate 5 are cut parallel by a shear, then the clamp 1 moves by a specified distance toward the clamp 2. Since the clamp 1 and the clamp 2 are connected on both sides by chucking mechanisms 9, 9 and therefore the clamping device has high strength and mechanical accuracy. On the other hand, if there is a deviation in the transverse direction of the plate 6 and the plate 5, the clamp 8 is moved in the transverse direction of the clamp 8 by a cross adjusting cylinder 4 attached to a cross adjusting clamp 8 provided separately from the clamp 8, by which the deviation is corrected.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a compact clamping device with high mechanical strength and precision, which is used in a pine seam welding machine and the like.

[Prior art]

FIGS. 1 and 2 are a plan view and a front view showing an example of a conventional clamp device. (5) is the trailing plate, (6) is the leading plate, (1) is the entry side clamp for clamping the trailing plate (5), and (2) is the clamp for clamping the leading plate (6). This is the exit side clamp. (3) is an index cylinder for moving the entry side clamp (1) toward the exit side clamp (2), and (4) is the index cylinder for moving the entry side clamp (1) toward the exit side clamp (2). This is a cross adjustment cylinder for moving to the same position. (7) is the common base that supports each member.

In the above device, first, the entry side clamp (1)
The leading plate (6) and trailing plate (5) are clamped by the exit side clamp (2). After the leading plate (6) and trailing plate (5) clamped at 2 are cut in parallel by a shear, the entry clamp (1) moves a certain distance in the direction of the exit clamp (2). In this case, the preceding board (6
) and the trailing plate (5), the entrance clamp (1) is moved in the same width direction by the cross adjustment cylinder (4) to correct the deviation.

According to the conventional clamp device configured as described above, the distance from the common space (7) to the clamp surface is large, and <, t+ connects the inlet clamp (1) and the outlet clamp (2). Since there is no mechanism, the strength of the clamping device is weak against the reaction force during shear cutting and welding, and the mechanical accuracy is poor, resulting in slipping of the leading plate (6) or trailing plate (5). There were drawbacks such as.

[Summary of the invention]

The present invention has been made to solve the above-mentioned drawbacks, and in order to obtain a compact clamping device with high strength and precision, a chucking mechanism is provided between the entry side clamp and the exit side clamp, and a chucking mechanism is provided between the entry side clamp and the exit side clamp. The present invention provides a clamp device characterized by a cross-adjust clamp mechanism provided separately from the clamp.

[Example of idea]

FIGS. 3 and 4 are a plan view and a front view showing an embodiment of the present invention. Note that parts having the same functions as those in FIGS. 1 and 2 are given the same symbols, and explanations thereof will be omitted. (9) is a chucking mechanism (connection mechanism), which is provided between the entry side clamp (1) and the exit side clamp (2). (8) is a cross adjustment clamp, which is provided separately from the entry side clamp (1).
The cross adjustment clamp (8) is provided with a cross adjustment cylinder (4). Note that since the entry side clamp (1) is not provided with the cross adjustment cylinder (4), the device can be lowered by that much.

A detailed explanation of the present invention configured as described above is as follows. First, the entry side clamp (1) and the exit side clamp (2)
) to clamp the leading plate (6) and the trailing plate (5). Clamped leading board (6) and trailing board (5)
is cut parallel by the shear, and then the entry side clamp (
1) moves a certain distance in the direction of the exit clamp (2). At this time, the entry side clamp (1) and the exit side clamp 1 (2)
) are connected on both sides by chucking mechanisms (9) and (9), so the clamping device has strong strength and high mechanical precision. - If there is a misalignment in the width direction of the leading plate (6) and trailing plate (5) of the sword, a cross-adjust cylinder attached to the entrance clamp (1) and a separate cross-adjust clamp (8) (4), the entry side clamp (
8) to the board width direction to correct the deviation.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the entry side clamp and the exit side clamp are connected, and the cross-adjust clamp mechanism is provided separately from the entry side clamp, so that the machine can be made smaller and more compact. A clan 1 device with good target strength and precision can be obtained.
