[0018] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present invention. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. Throughout the specification, similar parts are denoted by the same reference numerals.

[0019] Then, a part fixing workbench according to one embodiment of the present invention will be described with reference to FIGS. 1 to 5.

[0020] Referring to FIGS. 1 to 5, the part fixing workbench (1) according to the present embodiment includes a workbench body (10), a pin press part (20), and an operating part (30), and is capable of fixing parts of various shapes, thereby increasing the convenience of part assembly.

[0021] The workbench body (10) includes a base (11) and a leg member (13) and forms the base of the part fixing workbench (1).

[0022] The base (11) has a predetermined width and thickness. The interior of the base (11) is hollow. A load hole (11a) is formed on the upper surface of the base (11). Multiple load holes (11a) are formed at intervals along the X-axis and Y-axis directions.

[0023] A rim (12) protrudes from the upper edge of the base (11). An assembly space (10a) is formed on the upper surface of the base (11) by the rim (12).

[0024] The leg member (13) protrudes downward from the corner of the base (11). The leg member (13) supports the base (11). The leg member (13) may have a telescopic structure. Accordingly, the leg member (13) may be adjustable in length. Thus, the position of the base (11) can be adjusted according to the height of the worker.

[0025] Casters are attached to the leg members (13). This facilitates the movement of the part fixing workbench (1).

[0026] The pin press section (20) includes a support (21). The support (21) is located at each load hole (11a) and can support the part (P) in the assembly space (10a).

[0027] The support (21) includes a cylinder (211) and a rod (212). The support (21) may further include a buffer (22).

[0028] A cylinder (211) is positioned at each load hole (11a) and is placed inside the base (11). An operating fluid is contained inside the cylinder (211).

[0029] The rod (212) is combined with the cylinder (211) and protrudes through the rod hole (11a) to the upper part of the base (11). The upper end of the rod (212) can come into contact with the part (P). The rod (212) in contact with the part (P) can support the part (P) as it is retracted (downward) into the interior of the cylinder (211).

[0030] The cushioning part (22) includes a cap (221). Referring to Figure 4a), the cap (221) is detachably attached to the top of the rod (212). The upper surface of the cap (221) contacts the surface of the supporting part (P). The cap (221) may be made of rubber, silicone, foam, etc. The cap (221) prevents damage to the part (P) and elastically supports and secures the part (P).

[0031] Referring to Figure 4b), a plurality of protrusions (222) are protruded from the upper surface of the cap (221). The protrusions (222) are formed in a cylindrical shape and elastically support the part (P). The protrusions (222) can be made of the same material as the cap (221).

[0032] Referring to Figure 4c), a lamp (223) may be installed on the top of the rod (212). The lamp (223) is covered by a cap (221). The cap (221) may be made of a material that allows light to pass through. A proximity sensor (not shown) that detects contact with a part (P) is installed on the upper surface of the cap (221). When the proximity sensor detects the part (P), the lamp (223) may emit light. Accordingly, the lamp (223) of the support (21) that contacts the part (P) among the plurality of supports (21) may emit light. The position of the part (assembly position) may be indicated by the light emitted by the lamp (223).

[0033] The operating unit (30) includes a fluid tank (31) and a fluid pump (32) and withdraws the rod (212) that is inserted into the cylinder (211).

[0034] A case (30a) housing a fluid tank (31) and a fluid pump (32) is installed on one side of the base (11).

[0035] The fluid tank (31) is positioned inside the case (30a). The fluid tank (31) contains a working fluid. The fluid tank (31) has an injection hole (not shown) for injecting the working fluid and a drain hole (not shown) for discharging the working fluid.

[0036] The fluid pump (32) connects the fluid tank (31) and a plurality of cylinders (211) through a pipe through which the working fluid can flow. The pipe may be a flexible hose. By operating the fluid pump (32), the working fluid in the fluid tank (31) can be supplied to the cylinders (211). With the inflow of the working fluid, the rod (212) can be withdrawn from the cylinders (211).

[0037] Meanwhile, when the rod (212) is inserted into the cylinder (211), the working fluid of the cylinder (211) can flow into the fluid tank (31). The working fluid remaining in the cylinder (211) can support the inserted rod (212).

[0038] The following explains the operation of the part fixing workbench described above.

[0039] The rod (212) is withdrawn from the cylinder (211) and protrudes into the assembly space (10a). That is, the working fluid of the fluid tank (31) is introduced into the cylinder (211) by the operation of the fluid pump (32).

[0040] When a worker places a part (P) to be assembled in the assembly space (10a) on the pin press section (20), the cushioning section (22) supports the part. The rod (212) in contact with the part (P) is drawn into the cylinder (211) by the weight of the part (P). With the drawing of the rod (212), the working fluid of the cylinder (211) can flow into the fluid tank (31).

[0041] The inserted rod (212) supports the component (P). The buffer (22) supports the component (P) and fixes it elastically. Then, the lamp (223) can emit light by the proximity sensor that detects the component (P).

[0042] Accordingly, since the rod (212) is drawn in along the shape of the part (P), the part fixing workbench (1) can support and fix parts of various shapes. The assembly position is indicated by the light emitted by the lamp (223), thereby improving assembly efficiency.

[0043] Afterward, when the part (P) is lifted, the fluid pump (32) can be operated. The fluid pump (32) supplies the working fluid flowing into the fluid tank (31) to the cylinder (211). The inserted rod (212) can be withdrawn from the cylinder (211) and protrude into the assembly space (10a) due to the inflow of the working fluid.

[0044] Next, another embodiment of the present invention will be described with reference to Figure 5.

[0045] Referring to Figure 5, another embodiment of the present invention has a different structure for the operating part (30) described above.

[0046] In the base (11) according to the present embodiment, lifting holes (11b) are formed at intervals. A rod (212) is arranged in each lifting hole (11b). The rod (212) can be lifted up and down in the lifting holes (11b).

[0047] The operating part (30) according to the present embodiment includes an elastic member (33). The elastic member (33) has a coil spring structure. The elastic member (33) is not limited to a coil spring.

[0048] The elastic member (33) provides elastic force so that the rod (212) is pulled out of the lifting hole (11b) to the outside of the base (11).

[0049] When the part (P) is placed on the pin press section (20), the rod (212) is drawn into the lifting hole (11b) by the weight of the part (P). At this time, the elastic member (33) supports the rod (212) by cushioning it as it descends. Due to the elastic force of the elastic member (33), the cushioning section (22) can maintain contact with the part (P).

[0050] Afterwards, when the part (P) is removed, the rod (212) that has been lowered by the elastic force of the elastic member (33) can be raised.

[0051] Other configurations may be applied as they are from the embodiments of FIGS. 1 to 4.

[0052] Although preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims also fall within the scope of the present invention.
