Description

Technical Field

[0001] The utility model belongs to the field of positioning tools, and particularly relates to a positioning base for an A-frame. Background Art

[0002] Semi-finished glass produced by a factory itself or purchased externally is generally placed on an A-frame for fixation. During subsequent production, in order to facilitate the transfer of semi-finished glass by a feeding device, it needs to be moved to a positioning base at a designated position. The actual situation is that the sizes of A-frames used for different specifications of glass are different, and the sizes of A-frames used by different manufacturers are also different. Therefore, currently, different specifications of positioning bases need to be equipped to adapt to different specifications of A-frames, resulting in problems such as large floor space occupation, cumbersome replacement operations, and slow production efficiency. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a positioning base for an A-frame, which can be adjusted to adapt to different specifications of A-frames, reduces the floor space, simplifies the operation, and improves the production efficiency.

[0004] The utility model provides a positioning base for an A-frame, including a platform frame. A rectangular positioning area is arranged at the top of the platform frame. A positioning block is arranged on one side edge of the rectangular positioning area, and linear adjustment devices and movable limit plates are arranged on the other three side edges. The linear adjustment devices drive the movable limit plates in three directions to adjust the area of the rectangular positioning area, so as to position A-frame bodies of different specifications.

[0005] Optionally, the linear adjustment device includes a lead screw, a slide rail pair arranged parallel to the lead screw, and a bearing for fixing the lead screw. The movable limit plate is connected to the slide rail pair.

[0006] Optionally, the linear adjustment device further includes a manual rotating wheel for assisting the rotation of the lead screw.

[0007] Optionally, the linear adjustment device further includes a clamping member for restricting the rotation of the lead screw. The clamping member surrounds the screw rod of the lead screw.

The clamping block is provided with a central hole and a narrow slit extending from the central hole to the outside. The fastening member penetrates through the narrow slit, and the screw rod of the lead screw passes through the central hole. The screw rod of the lead screw is clamped by compressing the narrow slit with the fastening member.

[0009] Optionally, the linear adjustment device further includes a mounting plate arranged at one end of the slide rail pair. The bearing is arranged through the mounting plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] As Figures 1-4 shown, an A-type frame positioning base provided by the utility model includes a platform frame 100. A rectangular positioning area is provided at the top of the platform frame 100. A positioning block 110 is provided on one side of the rectangular positioning area, and linear adjustment devices 200 and movable limit plates 300 are provided on the other three sides. The linear adjustment devices 200 drive the movable limit plates 300 in three directions to adjust the area of the rectangular positioning area so as to position the A-type frame bodies 1.1 of different specifications.

[0021] Compared with the prior art, for the A-frame positioning bottom bracket provided by the utility model, the positioning block 110 on one side of the platform frame 100 defines the positive x-axis direction. By means of the linear adjustment devices 200 provided on the other three sides, the position of the movable limit plate 300 can be moved in the negative x-axis direction and the positive and negative y-axis directions, so that the movable limit plates 300 in the three directions and the positioning block 110 can abut against the periphery of the A-frame body 1.1 of different specifications, thereby enabling the rapid positioning of the A-frame body 1.1 of different specifications, reducing the floor area, simplifying the operation, and improving the production efficiency.

[0022] In one embodiment, the linear adjustment device 200 includes a lead screw 220, a slide rail pair 210 arranged parallel to the lead screw 220, and a bearing 230 for fixing the lead screw 220. The movable limit plate 300 is connected to the slide rail pair 210. Specifically, the slide rail pair 210 is fixed to the platform frame 100 by bolts, and the bearing 230 is also fixed on the platform frame 100. The ball sleeve of the lead screw 220 is rigidly connected to the movable limit plate 300 by fastening means such as bolts. The smooth part of the screw rod of the lead screw 220 passes through the bearing 230. When the screw rod is rotated by an external force, the ball sleeve moves linearly along the screw rod, driving the movable limit plate 300 to slide along the slide rail pair 210 to a specified position, thereby pushing the A-frame body 1.1 to adjust its position on the top surface of the platform frame 100 to meet the positioning requirements in the production process.

[0023] In one embodiment, in order to be able to rotate the lead screw 220 more labor-savingly, the linear adjustment device 200 further includes a manual rotating wheel 240 for assisting the rotation of the lead screw 220. The manual rotating wheel 240 is fixedly installed at the end of the screw rod of the lead screw 220. During use, when the manual rotating wheel 240 is rotated forward, the lead screw 220 drives the movable limit plate 300 to move inward, increasing the positioning area and adapting to the A-frame body 1.1 of a larger specification. When rotated in the opposite direction, the movable limit plate 300 moves outward, adapting to the A-frame body 1.1 of a smaller specification.

[0024] In one embodiment, in order to prevent the accidental rotation of the lead screw 220, the linear adjustment device 200 further includes a clamping member 250 for restricting the rotation of the lead screw 220. The clamping member 250 surrounds the screw rod of the lead screw 220. Specifically, after the movable limit plate 300 is adjusted in place, the screw rod of the lead screw 220 is clamped and restricted by the clamping member 250. If the movable limit plate 300 needs to be adjusted again, the clamping member 250 can be loosened.

[0025] Please refer to Figure 3 , a clamping member 250 includes a clamping block 251 and a fastener 252 screwed to the clamping block 251. The clamping block 251 is provided with a central hole and a narrow slit 253 extending outward from the central hole. The fastener 252 passes through the narrow slit 253, and the screw rod of the lead screw 220 passes through the central hole. The screw rod of the lead screw 220 is clamped by compressing the narrow slit 253 by the fastener 252.

[0026] In one embodiment, referring again to Figure 3 , the linear adjustment device 200 further includes a mounting plate 260 disposed at one end of the slide rail pair 210. The bearing 230 is disposed through the mounting plate 260. The mounting plate 260 serves to stabilize the bearing 230, making the lead screw 220 operate more smoothly.

[0027] In one embodiment, the movable limit plate 300 includes a flat plate 310 connected to the slide rail pair 210 and a strip plate 320 connected to one side of the top of the flat plate 310. The strip plate 320 is in contact with the bottom side edge of the A-shaped frame. Specifically, the flat plate 310 is a rectangular plate, and its bottom is fixedly connected to the sliders of the two slide rail pairs 210. The connection methods include but are not limited to bolt connection and welding fixation. The top surface of the flat plate 310 is slightly higher than the top surface of the platform frame 100, so that the strip plate 320 is in clearance fit with the top surface of the platform frame 100, which not only helps the movable limit plate 300 to maintain stability, but also prevents foreign objects from colliding with the linear adjustment device 200 and causing irreparable damage.

[0028] In one embodiment, a plurality of grooves 120 are provided on the top of the platform frame 100, and the linear adjustment device 200 is disposed in the grooves 120. With this setting, the linear adjustment device 200 is not easily collided by foreign objects in the grooves 120. At the same time, a relatively large operating space is provided on the platform frame 100.

[0029] In one embodiment, positioning blocks 110 are also provided on the other three sides of the rectangular positioning area. In this way, the maximum positioning area can be defined to avoid out-of-range and out-of-control situations.
