Abstract
Description
Technology Field
[0001] The present invention relates to an L-shaped positioner with an open workspace, and more specifically, to an L-shaped positioner with an open workspace that allows various operations on a heavy object placed on a workbench to be performed very conveniently by opening up the entire area except for the part where the base frame is located, through an L-shaped connecting frame firmly coupled to a base frame. Furthermore, it allows the position or orientation of the heavy object to be set very precisely by setting the left and right positions of the heavy object placed on the workbench through a vertical setting means and rotating the heavy object horizontally through a horizontal setting means, thereby enabling various operations on the heavy object to be performed more conveniently. Background Technology
[0002] Generally, a positioner is a device that provides convenience to the worker by establishing the position and posture of high-load workpieces (heavy objects) during tasks such as welding, repair, and inspection.
[0003] Conventional positioners in which heavy loads are placed are configured such that a heavy load is placed in the center and support frames on both sides are in close contact with the ground to support the center. However, since these support frames are equipped with various devices for setting the position or posture of the heavy load placed in the center, there was an inconvenience in that the sides of the heavy load were blocked, making it difficult for the worker to perform smooth operations on the heavy load.
[0004] Furthermore, conventional positioners have a problem in that the center of gravity varies as the position of the weight placed at the center is set in various ways, and because they fail to compensate for such changes in the center of gravity, a load is generated on the device due to the high load of the weight, and this load causes deformation or damage to the device. The problem to be solved
[0005] The present invention is proposed to solve the aforementioned problems, and its purpose is to provide an L-shaped positioner with an open workspace that allows various operations on a heavy object to be performed very conveniently by opening up the entire area excluding the part where the base frame is located, through an L-shaped connecting frame firmly coupled to a base frame, and further enables the position or orientation of the heavy object to be set very precisely by setting the left and right positions of the heavy object placed on the workbench through a vertical setting means and rotating the heavy object horizontally through a horizontal setting means, thereby making various operations on the heavy object even more convenient.
[0006] In addition, the invention provides an L-shaped positioner with an open workspace that can secure excellent structural safety of the device by minimizing problems of deformation or damage caused by the heavy load of the heavy object placed on the workbench through weight balance, while simultaneously compensating for the load of the heavy object when its position or orientation changes through vertical and horizontal setting means. means of solving the problem
[0007] An L-shaped positioner with an open workspace according to the present invention for achieving the above-mentioned purpose is characterized by comprising: a base frame; an L-shaped connecting frame having one end rotatably connected to the base frame and the other end formed horizontally; a workbench rotatably connected to the upper end of the connecting frame; a vertical setting means coupled to the base frame to rotate the connecting frame vertically; and a horizontal setting means coupled to one end of the connecting frame to rotate the workbench horizontally.
[0008] In addition, the other end of the connecting frame is positioned lower than the center of the second rotating gear, and the upper end of the connecting frame is positioned higher than the center of the second rotating gear.
[0009] It is characterized by further comprising a weight balance that compensates for the high load of a heavy object placed on a workbench formed at the other end of the connecting frame, which is coupled to the upper end of the connecting frame.
[0010] In addition, the other end of the above connecting frame is located at a position lower than the center of the second rotating gear, and
[0011] It is characterized by further comprising a weight balance having a predetermined load, positioned at one end of the connecting frame at a position higher than the center of the second rotating gear.
[0012] In addition, the horizontal setting means is characterized by comprising a horizontal drive unit that supplies rotational force, a third rotating gear that rotates by receiving rotational force from the horizontal drive unit, and a fourth rotating gear that is horizontally laid down and rotatably coupled and fixed to the other end of the connecting frame, the upper part of which is coupled to the work table, and which meshes with the third rotating gear to receive rotational force from the third rotating gear and rotates together with the work table.
[0013] In addition, the weight balance is characterized by comprising: a weight having a load; a horizontal transfer rod formed horizontally and having screw threads formed on its outer surface; a transfer block formed on the horizontal transfer rod and coupled with the weight, which travels along the horizontal transfer rod and moves in the left and right directions together with the weight when the horizontal transfer rod rotates; a rotary motor that provides rotational force to the horizontal transfer rod; a load box coupled with the rotary motor and accommodating the weight, the horizontal transfer rod, and the transfer block; and one or more lifting cylinders coupled to the connecting frame to raise and lower the load box. Effects of the invention
[0014] As described above, according to the L-shaped positioner with an open workspace according to the present invention, the entire area excluding the part where the base frame is located is open for a heavy object placed on a workbench by an L-shaped connecting frame that is firmly coupled to a base frame, thereby not only allowing various operations on the heavy object to be performed very conveniently, but also enabling the position or orientation of the heavy object to be set very precisely by setting the left and right positions of the heavy object placed on the workbench through a vertical setting means and rotating the heavy object horizontally through a horizontal setting means, thus providing the effect of making various operations on the heavy object more convenient.
[0015] In addition, by fundamentally compensating for the high load of heavy objects placed on the workbench through weight balance, and simultaneously compensating for the load of heavy objects whose position or orientation changes through vertical and horizontal setting means, it is possible to minimize problems such as deformation or damage to the device caused by the high load of heavy objects, thereby ensuring the excellent structural safety of the device.

[0017] An L-shaped positioner with an open workspace according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings. Detailed descriptions of known functions and configurations that are deemed to unnecessarily obscure the gist of the present invention are omitted.
[0018] FIGS. 1 to 5 illustrate an L-shaped positioner with an open workspace according to an embodiment of the present invention, where FIG. 1 is a perspective view of an L-shaped positioner with an open workspace according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of an L-shaped positioner with an open workspace illustrated in FIG. 1, FIG. 3 is a cross-sectional view AA of an L-shaped positioner with an open workspace illustrated in FIG. 1, FIG. 4 is a view of the L-shaped positioner with an open workspace illustrated in FIG. 1 in use, and FIG. 5 is a drawing illustrating an L-shaped positioner with an open workspace according to another embodiment of the present invention.
[0019] As illustrated in the drawing above, an L-shaped positioner (100) with an open workspace according to an embodiment of the present invention comprises a base frame (10), a connecting frame (20), a workbench (30), a vertical setting means (40), and a horizontal setting means (50).
[0020] As shown in FIGS. 1 to 3, the base frame (10) directly or indirectly supports the connecting frame (20), work table (30), vertical setting means (40), and horizontal setting means (50) to be described later, and can be made of a metal material having excellent strength and durability.
[0021] As shown in FIGS. 1 to 3, the connecting frame (20) is rotatably connected to the base frame (10) at one end and formed horizontally at the other end so as to be formed in an overall L shape.
[0022] Here, the other end of the connecting frame (20) is formed horizontally and the work table (30) is positioned on the upper part of the other end, so that, as shown in FIG. 4c, the entire part of the work table (30), excluding the part where the base frame (10) is located, can be exposed to the outside, thereby allowing various operations on heavy objects placed on the work table (30) to be performed very easily.
[0023] As shown in FIGS. 1 to 3, the workbench (30) is rotatably connected to the upper end of the connecting frame (20).
[0024] The above-mentioned work table (30) is used to support a heavy load to be worked on, and it goes without saying that a conventional jig (1) configuration that guides the heavy load to be stably fixed on the upper part can be used.
[0025] Here, the work table (30) can be freely positioned through the vertical and horizontal setting means (40, 50) to allow for positioning that facilitates working with heavy objects, and this will be explained in detail below.
[0026] As illustrated in FIGS. 1 to 3, the vertical setting means (40) is coupled to the base frame (10) to vertically rotate the connecting frame (20).
[0027] It is configured to include a vertical drive unit (41) that supplies rotational force, a first rotational gear (42) that rotates by receiving rotational force from the vertical drive unit (41), and a second rotational gear (43) that is vertically erected on the front of the base frame (10) and rotatably coupled and fixed, is coupled to one end of the connecting frame (20), and meshes with the first rotational gear (42) to receive rotational force from the first rotational gear (42) and rotates together with the connecting frame (20).
[0028] That is, as illustrated in FIG. 4b, the vertical setting means (40) rotates the connecting frame (20) vertically to set the left and right positions of the heavy load placed on the work table (30) formed at the other end of the connecting frame (20). Specifically, the first rotating gear (42) is rotated in one direction or the other direction through the vertical driving unit (41), and the connecting frame (20) is rotated in one direction or the other direction together with the second rotating gear (43) that meshes with the first rotating gear (42), thereby allowing the appropriate left and right positions of the heavy load placed on the work table (30) at the other end of the connecting frame (20) to be easily set.
[0029] As illustrated in FIGS. 1 to 3, the horizontal setting means (50) is coupled to one end of the connecting frame (20) to horizontally rotate the workbench (30).
[0030] It is configured to include a horizontal drive unit (51) that supplies rotational force, a third rotational gear (52) that receives rotational force from the horizontal drive unit (51) and rotates, and a fourth rotational gear (53) that is horizontally laid down on the other end of the connecting frame (20) and rotatably coupled and fixed, with its upper part coupled to the work table (30), and meshes with the third rotational gear (52) to receive rotational force from the third rotational gear (52) and rotates together with the work table (30).
[0031] That is, as illustrated in FIG. 4c, the horizontal setting means (50) rotates the work table (30) horizontally to appropriately set the position of a heavy load placed on the work table (30). Specifically, the third rotating gear (52) is rotated in one direction or the other through the horizontal driving unit (51), and the work table (30) is rotated in one direction or the other together with the fourth rotating gear (53) that meshes with the third rotating gear (52), thereby allowing the appropriate position of the heavy load placed on the work table (30) to be easily set.
[0032] Meanwhile, as shown in FIGS. 1 to 3, the other end of the connecting frame (20) is positioned lower than the center of the second rotating gear (43), and the upper end of the connecting frame (20) is positioned higher than the center of the second rotating gear (43).
[0033] It further comprises a weight balance (60) that compensates for the high load of a heavy object placed on the workbench (30) formed at the other end of the connecting frame (20) and coupled to the upper end of the connecting frame (20).
[0034] That is, as illustrated in FIG. 4a, the work table (30) is formed at the other end (front) of the connecting frame (20), and when a heavy object with a high load is placed on the work table (30), the load will increase toward the other end of the connecting frame (20). At this time, the load of the heavy object is compensated through the load of the weight balance (60) formed at the one end (rear) of the connecting frame (20), thereby basically relieving the load caused by the load shifting toward the front of the device due to the heavy object, and at the same time,
[0035] As illustrated in FIG. 4b, when the connecting frame (20) is rotated in one direction or the other through the vertical setting means (40), the work table (30) of the connecting frame (20) is positioned to the left or right. At this time, the weight balance (60) formed on one side of the connecting frame (20) is naturally positioned to the right or left side opposite to the work table (30) to compensate for the load of the heavy object, thereby relieving the load caused by the load shifting to the side of the device due to the heavy object positioned to the left or right, and ensuring the structural safety of the device.
[0036] Meanwhile, as illustrated in FIG. 5, the weight balance (60) comprises a weight (61) having a load, a horizontal transfer rod (62) formed horizontally and having screw threads (62a) formed on its outer surface, a transfer block (63) formed on the horizontal transfer rod (62) and coupled with the weight (61) so that when the horizontal transfer rod (62) rotates, it travels along the horizontal transfer rod (62) and is transferred in the left and right directions together with the weight (61), a rotary motor (64) providing rotational force to the horizontal transfer rod (62), a load box (65) coupled with the rotary motor (64) and accommodating the weight (61), the horizontal transfer rod (62), and the transfer block (63), and one or more lifting cylinders (66) coupled to the connecting frame (20) to raise and lower the load box (65).
[0037] That is, if the load on the workbench (30) is not formed uniformly and is skewed to one side due to the irregular shape of the heavy object placed on the workbench (30), the horizontal transfer rod (62) is rotated through the rotation motor (64) of the weight balance (60) so that the transfer block (63) is transferred in the left and right directions together with the weight (61), thereby compensating for the load skewed to one side on the workbench (30) and enabling precise load compensation of the heavy object.
[0038] After that, when the workbench (30) is rotated together with the connecting frame (20) through the vertical setting means (40), the weight balance (60) is positioned on the opposite side of the workbench (30) to compensate for the load. At this time, if the total load of the workbench is somewhat heavy or, conversely, somewhat light, the load box (65) containing the weight (61) is raised or lowered through the lifting cylinder (66) so that the load of the workbench can be precisely compensated through the weight (61).
[0039] The L-shaped positioner (100) of the present invention, which has an open workspace and is composed of the above-described components, allows the entire area of the heavy object placed on the workbench (30) to be open except for the area where the base frame (10) is located, thereby enabling various operations on the heavy object to be performed very conveniently. In addition, the position or posture of the heavy object can be set very precisely by setting the left and right positions of the heavy object placed on the workbench (30) through the vertical setting means (40) and rotating the heavy object horizontally through the horizontal setting means (50), thus providing the effect of enabling various operations on the heavy object to be performed more conveniently.
[0040] In addition, the high load of the heavy object placed on the workbench (30) is basically compensated through the weight balance (60), and at the same time, the load of the heavy object whose position or posture is changed is compensated through the vertical and horizontal setting means (40, 50), thereby minimizing problems such as deformation or damage to the device caused by the high load of the heavy object, and thus ensuring excellent structural safety of the device.
[0041] The L-shaped positioner (100) with an open working space according to an embodiment of the present invention having the above configuration allows the position of the heavy object to be worked on to be appropriately set as follows, thereby enabling the work on the heavy object to be easily performed.
[0042] First, as shown in FIG. 4a, a heavy object of high load to be worked on is placed and fixed on the upper part of the work table (30). At this time, the load of the heavy object placed on the work table (30) is compensated by a weight balance (60) formed at one end of the connecting frame (20) to induce stable placement of the heavy object.
[0043] Here, the heavy load placed on the workbench (30) can be securely fastened using a conventional jig (1), and it goes without saying that the heavy load can be easily moved to the workbench (30) using a conventional crane or hoist or other moving equipment (not shown).
[0044] Then, as shown in FIG. 4b, the workbench (30) is rotated in the left and right directions together with the connecting frame (20) through the vertical setting means (40) to appropriately set the left and right positions of the heavy object placed on the workbench (30).
[0045] At this time, the weight balance (60) is positioned on the opposite side of the heavy object placed on the workbench (30) and naturally compensates for the load of the heavy object in the left and right directions, thereby inducing stable placement of the heavy object.
[0046] Then, as shown in FIG. 4c, the work table (30) is horizontally rotated through the horizontal setting means (50) to appropriately set the position of the heavy object placed on the work table (30), so that the worker can easily perform work on the heavy object.
[0047] Here, the work table (30) is positioned at the end of the L-shaped connecting frame (20), and since the work table (30) is open in all directions except the rear where the base frame (10) is located, the worker can very easily perform work on heavy objects without interference.

Furthermore, modifications by those skilled in the art are possible within the scope that does not deviate from the spirit of the present invention.
