[0031] Reference below Figures 1 to 5 A plate clamping fixture according to an embodiment of the utility model is described in detail.

[0032] According to some embodiments of the present invention, a plate clamping jig includes a jig body 100 and at least one clamping unit 200. The jig body 100 is provided with a clamping area 110, and the clamping area 110 is used to place the plate; each clamping unit 200 is arranged on the jig body 100 and adjacent to the clamping area 110, and the clamping unit 200 includes a clamping block 210 and an elastic member 220, and the clamping block 210 includes a clamping portion 211, a pushing portion 212 and a hinge portion 213, and the clamping portion 211 The pushing portion 212 is arranged on one side of the hinge portion 213 close to the clamping area 110. The hinge portion 213 is rotatably arranged relative to the fixture body 100. The clamping portion 211 is used to clamp the plate in the clamping area 110 in the clamping area 110. The pushing portion 212 is used to drive the clamping portion 211 away from the clamping area 110 under the action of an external force to loosen the plate. The elastic member 220 connects the fixture body 100 and the clamping block 210, and is used to provide an elastic force for the clamping block 210 to clamp the plate in the clamping area 110.

[0033] For example, Figures 1 to 3 As shown, in some embodiments of the present invention, a plate clamping jig includes a jig body 100, and the jig body 100 is provided with two clamping areas 110, and a plate can be placed in each clamping area 110, and each clamping area 110 is correspondingly provided with six clamping units 200, and each clamping unit 200 is arranged on the jig body 100 and is adjacent to the clamping area 110 corresponding to the clamping unit 200, and the clamping unit 200 includes a clamping block 210 and an elastic member 220, and the clamping block 210 includes a clamping portion 211, a pushing portion 212 and a hinged portion 213, and the clamping portion 211 and the hinged portion 213 are respectively connected to opposite ends of the pushing portion 212, and the clamping portion 211 and the pushing portion 212 are arranged on one side of the hinged portion 213 close to the clamping area 110, and the hinged portion 213 is rotatably arranged relative to the jig body 100, and the elastic member 220 connects the jig body 100 and the clamping block 210.

[0034] During the operation of the plate clamping jig of the present application, since the clamping block 210 is rotatably connected to the jig body 100 through the hinge 213, the clamping portion 211 is able to rotate around the hinge 213 following the pushing portion 212 by applying force to the pushing portion 212, and the clamping portion 211 is away from the clamping area 110. At this time, the plate is placed in the clamping area 110, and the force applied to the pushing portion 212 is removed. Since the elastic member 220 connects the jig body 100 and the clamping block 210, the clamping portion 211 rotates around the hinge 213 under the action of the elastic force provided by the elastic member 220, and the clamping portion 211 approaches the clamping area 110, and clamps the plate placed in the clamping area 110 in the clamping area 110. Since the clamping portion 211 and the pushing portion 212 are both arranged on the side of the hinge portion 213 close to the clamping area 110, when the rotation stroke required for the panel clamping or unclamping working process is met, the clamping block 210 basically does not need to be rotated to the outside of the panel clamping fixture (that is, the projection of the clamping block 210 on the plane where the fixture body 100 is located during the working process can basically fall within the range where the fixture body 100 is located). Therefore, the space required during use is smaller, and it is not easy to interfere with other structures.

[0035] In some embodiments of the present invention, the clamping unit 200 further includes a mounting seat 300, which is detachably disposed on the fixture body 100, and the hinge portion 213 is rotatably connected to the mounting seat 300. Figure 1 and Figure 2As shown, the mounting seat 300 includes a mounting shaft 310 and two mounting blocks 320, the two mounting blocks 320 are respectively connected to the opposite ends of the mounting shaft 310, and the mounting blocks 320 are detachably connected to the fixture body 100, and the mounting shaft 310 is rotatably sleeved with a hinged portion 213. It can be understood that the hinged portion 213 is rotatably sleeved on the mounting shaft 310, and when the pushing portion 212 drives the clamping portion 211 to rotate, the clamping portion 211 rotates around the mounting shaft 310; since the clamping block 210 is connected to the two mounting blocks 320 through the mounting shaft 310, and the two mounting blocks 320 are detachably connected to the fixture body 100, when it is necessary to disassemble the clamping unit 200, the staff can remove the clamping unit 200 from the fixture body 100 by disassembling the mounting block 320.

[0036] It can be understood that the number of mounting blocks 320 can be adjusted according to actual needs and is not limited to two in the above embodiment.

[0037] refer to Figure 3 In some embodiments, the elastic member 220 is a torsion spring, which includes a first abutting portion 221, a second abutting portion 222 and an elastic portion 223. The first abutting portion 221 and the second abutting portion 222 are connected through the elastic portion 223. The first abutting portion 221 abuts against the pushing portion 212, and the second abutting portion 222 abuts against the fixture body 100. The elastic portion 223 is sleeved on the mounting shaft 310. It can be understood that the pushing portion 212 drives the clamping portion 211 away from the clamping area 110 under the action of force. Since the second abutting portion 222 abuts against the fixture body 100 and the elastic portion 223 is sleeved on the mounting shaft 310, the first abutting portion 221 rotates with the pushing portion 212, and the torsion spring twists and stores elastic potential energy. When the force applied to the pushing portion 212 is removed, the torsion spring releases the elastic potential energy and provides elastic force to the pushing portion 212 through the first abutting portion 221, so that the clamping portion 211 rotates driven by the pushing portion 212 until the plate in the clamping area 110 is clamped in the clamping area 110.

[0038] In some embodiments of the present invention, Figure 5As shown, the jig body 100 is provided with an avoidance through hole 120, which corresponds to the clamping unit 200 one by one, and the pushing portion 212 is directly opposite to the avoidance through hole 120, and the avoidance through hole 120 can allow the push rod to pass through and push the pushing portion 212. It can be understood that a push rod is provided on the side of the jig body 100 away from the clamping unit 200, and the push rod corresponds to the avoidance through hole 120 one by one. The push rod is connected to a driver. Before clamping the plate, under the drive of the driver, the push rod can pass through the avoidance through hole 120 and push the pushing portion 212. Driven by the pushing portion 212, the clamping portion 211 can overcome the elastic force of the elastic member 220 and rotate around the hinge portion 213 to move away from the clamping area 110, so that the plate can be placed in or out of the clamping area 110.

[0039] In some embodiments, the fixture body 100 includes a plurality of frame bars 130, the plurality of frame bars 130 are connected to each other and enclose at least one clamping area 110, and the clamping unit 200 is disposed on the frame bars 130 adjacent to the clamping area 110. For example, in one embodiment, Figure 4 As shown, the fixture body 100 includes five frame bars 130, including two first frame bars arranged at intervals along the first direction, three second frame bars arranged at intervals along the second direction, the extension direction of the first frame bars is the second direction, the extension direction of the second frame bars is the first direction, the three second frame bars are respectively connected to the two first frame bars at both ends of the first direction, the two first frame bars and the three second frame bars are enclosed to form two clamping areas 110, and the clamping unit 200 is arranged on the frame bars 130 that enclose the clamping area 110. It can be understood that the fixture body 100 is composed of a plurality of frame bars 130 connected to each other, and the frame bars 130 are enclosed to form a clamping area 110, so that the plate can be placed in the clamping area 110, and the edge of the plate is supported by the frame bars 130, ensuring that the plate can be placed in the clamping area 110 while saving the manufacturing cost of the plate clamping fixture.

[0040] In some embodiments of the present invention, part of the frame strip 130 is provided with an abutment boss 140 protruding into the clamping area 110, and the abutment boss 140 is used to abut against the side of the plate away from the clamping portion 211 to cooperate with the clamping portion 211 to clamp the plate. Figure 1 and Figure 4As shown, a first frame bar enclosing the clamping area 110 is provided with an abutment boss 140 protruding into the clamping area 110, and each second frame bar enclosing the clamping area 110 is provided with an abutment boss 140 protruding into the clamping area 110. It can be understood that when the plate is placed in the clamping area 110, the opposite sides of the plate in the thickness direction can respectively abut against the abutment boss 140 and the clamping portion 211, thereby achieving clamping and fixing of the plate. It can be understood that by providing the abutment boss 140 in a first frame bar enclosing the clamping area 110, the support effect of the fixture body 100 on the plate can be further enhanced.

[0041] It is understandable that in some other embodiments of the present invention, only the abutment bosses 140 protruding into the clamping area 110 may be provided on each of the second frame bars enclosing the clamping area 110 .

[0042] In other embodiments of the present invention, the abutment boss 140 protruding into the clamping area 110 may be provided only on the first frame strip enclosing the clamping area 110 .

[0043] In some embodiments of the present invention, the frame strips 130 provided with the clamping units 200 are all provided with abutment bosses 140. Figure 1 and Figure 4 As shown, in one embodiment, each second frame bar enclosing the clamping area 110 is provided with a clamping unit 200, and each second frame bar provided with the clamping unit 200 is provided with an abutting boss 140 protruding into the clamping area 110. It can be understood that when the plate is placed in the clamping area 110, for the edge portion of the plate close to the second frame bar, its opposite sides can respectively abut against the abutting boss 140 and the clamping portion 211, thereby achieving clamping and fixing of the plate.

[0044] In some embodiments, each clamping area 110 is provided with two clamping unit groups, and the two clamping unit groups are arranged on opposite sides of the clamping area 110, and each clamping unit group includes at least two clamping units 200. Figure 1 and Figure 4 As shown, in one embodiment, each clamping area 110 is correspondingly provided with two groups of clamping unit groups, and the two groups of clamping units 2 are respectively arranged on two second frame bars enclosing the clamping area 110, and are respectively located on the opposite sides of the clamping area 110, and each group of clamping units includes 3 spaced apart clamping units 200.

[0045] It can be understood that the number of clamping units 200 in each clamping unit group, in addition to at least two in the above-mentioned embodiments, can be determined according to actual needs. For example, in some other embodiments of the present invention, the width of the plate is narrow, so each clamping unit group includes a clamping unit 200.

[0046] In one embodiment of the present invention, the clamping unit 200 further includes a clamping rod 230, which is connected to the clamping portion 211 and is used to abut against the plate. The clamping rod 230 is parallel to the abutting boss 140 provided on the same frame bar 130. Figure 4 and Figure 5 As shown, in one embodiment, the clamping unit 200 further includes a clamping rod 230, which is connected to the clamping portion 211 and is located at one end of the clamping portion 211 close to the abutting boss 140, and the extension direction of the clamping rod 230 is parallel to the extension direction of the abutting boss 140 provided on the same frame bar 130. It can be understood that when the plate is located in the clamping area 110, the abutting boss 140 can support the edge of the plate, and when the pushing portion 212 drives the clamping portion 211 to rotate around the hinge portion 213 under the elastic force provided by the elastic member 220, the clamping rod 230 rotates accordingly until the outer peripheral surface of the clamping rod 230 abuts against the side of the plate away from the abutting boss 140. Since the extension direction of the clamping rod 230 is parallel to the extension direction of the abutting boss 140, the clamping unit 200 can clamp the plate in a wider range.

[0047] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
