Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire cutting machine tools, in particular to a rotary clamp for wire cutting machine tools. Background Art
[0002] Cutting machine tools belong to the category of electrical machining. When the Lazarenkos studied the phenomenon and causes of switch contacts being damaged by spark discharge corrosion, they found that the instantaneous high temperature of the electric spark can cause local metal to melt, oxidize and corrode, thus creating and inventing the electric spark machining method. Wire cutting machine tool processing is a branch of electric spark machining. It is a process method that directly uses electric sparks for machining. It uses a moving wire (electrode wire) as a tool electrode to cut the workpiece, so it is called wire cutting. In wire cutting, the relative movement of the workpiece and the electrode wire is realized by digital control, so it is also called CNC electric spark wire cutting, or wire cutting for short.
[0003] The existing wire cutting machine tool is a vise-type clamp, which includes a horizontally placed workpiece placement plate with a hollow middle for the cutting wire to pass through. A rotating threaded rod combined with a push plate structure is used on the workpiece placement plate. The rotating threaded rod pushes the push plate to firmly clamp the workpiece.
[0004] The above-mentioned prior art solutions have the following defects: the workpiece placement plate is generally a horizontal plate, and the workpiece placed on the workpiece placement plate can only be placed and clamped horizontally. When the workpiece needs to be cut obliquely, the inclination angle of the workpiece cannot be adjusted, and the processing requirements cannot be met. Utility Model Content
[0005] The utility model aims to provide a rotary clamp for a wire cutting machine tool.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] It includes a base plate, a pair of side plates arranged in parallel and at intervals are fixedly provided on the top wall of the base plate, a workpiece placement plate is hingedly provided between the side plates, a vise is fixedly provided on the top wall of the workpiece placement plate, a wire groove is provided through the workpiece placement plate and the base plate, an arc groove is provided through the side plate, a limiting column passing through the arc groove is fixedly provided on the end of the workpiece placement plate away from the hinged part, the limiting column is positioned and slidably provided along the curvature direction of the arc groove, and an adjusting device for controlling the positioning and placement of the limiting column is fixedly provided on the outer side wall of the side plate.
[0008] By adopting the above technical solution, the bench vise clamps the workpiece and places it on the workpiece placement plate. The setting of the wire groove facilitates the cutting wire to pass through the equipment to cut the workpiece. The limit column rotates along the arc groove. The adjustment device has a good adjustment effect and can effectively control the positioning and placement of the limit column. Therefore, the hinged workpiece placement plate can adjust the workpiece to a suitable cutting angle, so that a certain angle is maintained between the cutting wire and the workpiece, and the bevel cutting of the workpiece achieves the best processing effect.
[0009] Furthermore, the adjustment device includes a sliding block arranged to slide linearly along the outer wall of the side panel and a driving device for driving the sliding block to slide, the sliding area of the sliding block covers an arc groove, a horizontal movable groove is opened on a side of the sliding block close to the side panel, and the limit column is engaged with the movable groove and is arranged to slide horizontally.
[0010] By adopting the above technical solution, the height of the limit column can be effectively adjusted during the linear sliding process of the sliding block. The horizontal movable groove provides a good activity space, allowing the limit column to move laterally. When the sliding block rises or falls, the limit column will adaptively adjust its position in the movable groove. The angle of the workpiece placement plate can be adjusted by controlling the height position of the sliding block.
[0011] Furthermore, a clamping block with a protruding outer edge is fixedly provided at the end of the limiting column, and a clamping groove for horizontal sliding of the clamping block is formed on the wall of the movable groove.
[0012] By adopting the above technical solution, the locking block cooperates with the locking groove to firmly lock the limit column and the movable groove, thereby preventing the limit column from deviating during the sliding process and affecting the adjustment and scheduling of the workpiece placement plate, and effectively ensuring that the limit column slides stably and strictly in the specified direction.
[0013] Furthermore, the driving device includes positioning plates arranged in pairs on the outer walls of the side plates, the positioning plates are penetrated by a driving rod with a thread in the middle, the driving rod is threadedly connected to a sliding block, both ends of the driving rod are fixed with limit plates that abut against the outer walls of the positioning plates, and the end of the driving rod is fixed with a rotating handle.
[0014] By adopting the above technical solution, when the handle is turned, the position of the threaded sliding block can rise or fall according to the rotation direction, thereby achieving the effect of driving the sliding block to slide. The setting of the limit plate ensures that the driving rod and the positioning plate maintain a stable rotational connection, which has a good limiting effect.
[0015] Furthermore, a horizontally mounted transparent shell is embedded in the middle of the limiting column, and a proper amount of solution is filled inside the transparent shell. The amount of solution added is smaller than the volume of the internal cavity of the transparent shell, and a marking line is engraved in the middle of the transparent shell.
[0016] By adopting the above technical solution, since the amount of solution added is smaller than the volume of the internal cavity of the transparent shell, bubbles of a certain size will exist in the transparent shell, and the position of the bubbles can accurately reflect the placement angle of the workpiece placement plate in the horizontal direction. When the two ends of the limit column are at different heights, the bubbles will deviate from the marking line in the middle and move toward the two ends of the transparent shell. The transparent shell with bubbles makes it easy for on-site operators to adjust the height of the two ends of the limit column, ensuring that the workpiece can be placed completely flat, and has a good leveling effect.
[0017] In summary, the beneficial technical effects of the utility model are:
[0018] 1. The side plate, workpiece placement plate and adjustment device are used to keep a certain angle between the cutting wire and the workpiece, so that the bevel cutting of the workpiece can achieve the best processing effect;
[0019] 2. The sliding block and movable slot are used to control the height position of the sliding block and adjust the angle of the workpiece placement plate;
[0020] 3. A transparent shell and an appropriate amount of solution are used to produce a leveling workpiece placement frame to ensure that the workpiece can be placed and fit on the workpiece placement frame to avoid unevenness on the left and right ends. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The base plate 1 includes a pair of side plates 2 arranged in parallel and spaced apart, a workpiece placement plate 3 is hingedly arranged between the side plates 2, a vise fixture 4 is fixedly arranged on the top wall of the workpiece placement plate 3, a wire groove 11 is penetrated through the workpiece placement plate 3 and the base plate 1, an arc groove 21 is penetrated through the side plate 2, a limiting column 22 passing through the arc groove 21 is fixedly arranged at one end of the workpiece placement plate 3 away from the hinged part, the limiting column 22 is positioned and slidably arranged along the arc direction of the arc groove 21, and a control The limiting column 22 is positioned by the adjusting device 5, and the vise clamp 4 clamps the workpiece firmly and places it on the workpiece placement plate 3. The arrangement of the wire groove 11 facilitates the cutting wire to pass through the equipment to cut the workpiece. The limiting column 22 rotates along the arc groove 21. The adjusting device 5 has a good adjustment effect and can effectively control the positioning and placement of the limiting column 22. Therefore, the hinged workpiece placement plate 3 can adjust the workpiece to a suitable cutting angle, so that a certain angle is maintained between the cutting wire and the workpiece, and the bevel cutting of the workpiece achieves the best processing effect.
[0030] The adjusting device 5 includes a sliding block 51 which is arranged to slide linearly along the outer wall of the side plate 2 and a driving device 6 which drives the sliding block 51 to slide. The sliding area of the sliding block 51 covers the arc groove 21. A horizontal movable groove 61 is provided on a side of the sliding block 51 close to the side plate 2. The limiting column 22 is engaged with the movable groove 61 and is arranged to slide horizontally. The sliding block 51 can effectively adjust the height of the limiting column 22 during the linear sliding process. The horizontal movable groove 61 provides a good activity space, allowing the limiting column 22 to move laterally. When the sliding block 51 rises or falls, the limiting column 22 will adaptively adjust its position in the movable groove 61. The angle of the workpiece placement plate 3 can be adjusted by controlling the height position of the sliding block 51.
[0031] A locking block 221 with a protruding outer edge is fixedly provided at the end of the limiting column 22, and a locking groove 611 is opened on the wall of the movable groove 61 for the locking block 221 to slide horizontally. The locking block 221 cooperates with the locking groove 611 to firmly lock the limiting column 22 and the movable groove 61, thereby preventing the limiting column 22 from deviating during the sliding process and affecting the adjustment and scheduling of the workpiece placement plate 3, and effectively ensuring that the limiting column 22 slides stably and strictly along the specified direction.
[0032] The driving device 6 includes positioning plates 62 arranged in pairs on the outer walls of the side plates 2. The positioning plates 62 are penetrated by a driving rod 63 with a thread in the middle. The driving rod 63 is threadedly connected to the sliding block 51. Limiting plates 64 that abut against the outer walls of the positioning plates 62 are fixedly arranged at both ends of the driving rod 63. A rotating handle 65 is fixedly arranged at the end of the driving rod 63. When the rotating handle 65 is rotated, the position of the threaded sliding block 51 can rise or fall according to the rotation direction, thereby achieving the effect of driving the sliding block 51 to slide. The setting of the limiting plate 64 ensures that the driving rod 63 and the positioning plate 62 maintain a stable rotation connection, which has a good limiting effect.
[0033] A horizontally mounted transparent shell 7 is embedded in the middle of the limiting column 22, and an appropriate amount of solution is filled inside the transparent shell 7. The amount of solution added is less than the volume of the internal cavity of the transparent shell 7. A marking line is engraved in the middle of the transparent shell 7. Since the amount of solution added is less than the volume of the internal cavity of the transparent shell 7, bubbles of a certain size will exist in the transparent shell 7. The position of the bubble can accurately reflect the placement angle of the workpiece placement plate 3 in the horizontal direction. When the two ends of the limiting column 22 are at different heights, the bubble will deviate from the marking line in the middle and move toward the two ends of the transparent shell 7. The transparent shell 7 with bubbles makes it easy for on-site operators to adjust the height of the two ends of the limiting column 22 to ensure that the workpiece can be placed completely flat, which has a good leveling effect.
