Description

Technical Field

[0001] This utility model relates to the field of intelligent interactive screen processing technology, and in particular to a frame processing positioning fixture. Background Technology

[0002] When CNC machining the frame of a smart interactive screen, the frame needs to be positioned and fixed to ensure CNC machining accuracy. Currently, production lines often use pins to fix the beginning and end of each frame on the worktable. After the frame is machined, the pins are removed and the frame is released. However, this method is prone to missing pins, which can interfere with the milling cutter and damage the milling cutter in subsequent machining. In addition, the machining efficiency is low. For example, the utility model patent application with application number 202322232132.4 uses a clamping mechanism with multiple acupoints and an L-shaped plate to clamp and position the frame at multiple positions. This method better ensures the reliable positioning and fixing of each frame and avoids the problem of missing pins. However, the structure is more complex. Utility Model Content

[0042] This application provides a frame processing positioning fixture. The frame processing positioning fixture includes a processing support member, a positioning member, and a fastening assembly. A limiting channel is provided on one side of the processing support member, and the two groove walls of the limiting channel are used to abut against the side walls of the frame. The positioning member is located at either end of the limiting channel, and the positioning member at least partially abuts against the end wall of the frame. The fastening assembly includes a telescopic rotary cylinder and a clamping member. The telescopic rotary cylinder is connected to the processing support member, and the power end of the telescopic rotary cylinder is connected to the clamping member.

[0043] The aforementioned frame processing positioning fixture has a limiting channel on one side of the processing carrier, and the two groove walls of the limiting channel are used to abut against the two side walls of the frame. The positioning member is located at either end of the limiting channel and abuts against the end wall of the frame, thus achieving horizontal limiting and fixing of the frame. In conjunction with this, the telescopic rotary cylinder drives the clamping member to move towards or away from the processing carrier and drives the clamping member to rotate. The telescopic rotary cylinder drives the clamping member to move towards the processing carrier and rotate until it at least partially protrudes from the side wall of the limiting channel and abuts against the side wall of the frame, so that the frame is clamped between the processing carrier and the clamping member, thus achieving vertical limiting and fixing of the frame. In this way, the cylinder drives the clamping member to move away from the processing carrier and rotate until it is separated from the side wall of the frame and misaligned with the limiting channel. That is, when the frame is placed in the limiting channel, the clamping member and the limiting channel are misaligned, so that the clamping member will not interfere with the limiting channel, improving the convenience of frame placement.

[0044] To better understand the edge processing positioning fixture of this application, the following further explanation is provided:

[0045] Please refer to the following: Figures 1 to 4 ,as well as Figure 7 One embodiment of the frame processing positioning fixture 10 includes a processing support member 100, a positioning member 200, and a fastening assembly 300. A limiting channel 101 is provided on one side of the processing support member 100. See also... Figure 7The two groove walls of the limiting channel 101 are used to abut against the two side walls of the frame 20. The positioning member 200 is located at either end of the limiting channel 101, and the positioning member 200 is at least partially used to abut against the end wall of the frame 20. The fastening assembly 300 includes a telescopic rotary cylinder 310 and a clamping member 320. The telescopic rotary cylinder 310 is connected to the processing carrier 100, and the power end of the telescopic rotary cylinder 310 is connected to the clamping member 320. The telescopic rotary cylinder 310 drives the clamping member 320 to move toward or away from the processing carrier 100 and drives the clamping member 320 to rotate. The telescopic rotary cylinder 310 drives the clamping member 320 to move towards the processing support member 100 and rotate until it at least partially protrudes from the side wall of the limiting channel 101 and abuts against the side wall of the frame 20, so that the frame 20 is clamped between the processing support member 100 and the clamping member 320; the telescopic rotary cylinder 310 drives the clamping member 320 to move away from the processing support member 100 and rotate until it disengages from the side wall of the frame 20 and is misaligned with the limiting channel 101. Further, the telescopic rotary cylinder 310 is connected to the worktable, and the power output end of the telescopic rotary cylinder 310 is positioned away from the processing support member 100.

[0046] The aforementioned frame processing positioning fixture 10 provides a limiting channel 101 on one side of the processing support member 100. The two groove walls of the limiting channel 101 abut against the two side walls of the frame 20, and the positioning member 200 is located at either end of the limiting channel 101 and abuts against the end wall of the frame 20, thus achieving horizontal limiting and fixing of the frame 20. This, in conjunction with the telescopic rotary cylinder 310, drives the clamping member 320 to move closer to or further away from the processing support member 100 and rotates the clamping member 320. The telescopic rotary cylinder 310 also drives the clamping member 320 to move closer to the processing support member 100 and rotate until it at least partially protrudes from the limiting channel 101. The side wall of the frame 20 is abutted against the side wall of the frame 20, so that the frame 20 is clamped between the processing support member 100 and the clamping member 320, thus realizing the vertical positioning and fixing of the frame 20. In this way, the positioning and fixing of the frame 20 is well secured and the structure is simple. In addition, the telescopic rotary cylinder 310 drives the clamping member 320 to move away from the processing support member 100 and rotate until it is separated from the side wall of the frame 20 and misaligned with the limiting channel 101. That is, when the frame 20 is placed in the limiting channel 101, the clamping member 320 is misaligned with the limiting channel 101, so that the clamping member 320 will not interfere with the limiting channel 101, improving the placement convenience of the frame 20.

[0047] Please refer to the following: Figures 1 to 4 ,as well as Figure 7In one embodiment, there are multiple fastening components 300, which are spaced apart along the extension direction of the limiting channel 101. Further, the telescopic rotary cylinder 310 of each fastening component 300 is connected to the processing support member 100, and the telescopic rotary cylinder 310 of each fastening component 300 drives the corresponding clamping member 320 to move towards or away from the processing support member 100 and drives the corresponding clamping member 320 to rotate. Further, the telescopic rotary cylinder 310 of each fastening component 300 drives the corresponding clamping member 320 to move towards the processing support member 100 and rotate until it at least partially protrudes from the sidewall of the limiting channel 101 and abuts against the sidewall of the frame 20; the telescopic rotary cylinder 310 of each fastening component 300 also drives the corresponding clamping member 320 to move away from the processing support member 100 and rotate until it detaches from the sidewall of the frame 20 and is misaligned with the limiting channel 101. Furthermore, the clamping member 320 of one of the fastening components 300 is positioned near the positioning member 200, which further improves the reliability of the horizontal positioning and fixing of the frame 20.

[0048] Please refer to the following: Figures 1 to 4 ,as well as Figure 7 In one embodiment, the processing support 100 is provided with a plurality of limiting channels 101, each limiting channel 101 extending in the same direction as the length of the processing support 100, and the plurality of limiting channels 101 are linearly arranged along the width direction of the processing support 100. Further, a positioning member 200 is located at one end of each limiting channel 101. Further, at least one fastening assembly 300 is provided between every two adjacent limiting channels 101, and the telescopic rotary cylinder 310 of each fastening assembly 300 is connected to the processing support 100. The telescopic rotary cylinder 310 of each fastening assembly 300 drives the corresponding clamping member 320 to move towards or away from the processing support 100 and drives the corresponding clamping member 320 to rotate. Furthermore, the telescopic rotary cylinder 310 of each fastening component 300 drives the corresponding clamping member 320 to move toward the processing support member 100 and rotate to at least partially protrude from the sidewalls of the two adjacent limiting channels 101 and abut against the sidewalls of the two corresponding frame 20 respectively; the telescopic rotary cylinder 310 of each fastening component 300 drives the corresponding clamping member 320 to move away from the processing support member 100 and rotate to disengage from the sidewalls of the two adjacent frame 20 and be misaligned with the two corresponding limiting channels 101 respectively, thereby realizing the simultaneous limiting and fixing of multiple frame 20 and improving the processing efficiency of the frame 20.

[0049] Please refer to the following: Figures 1 to 4 ,as well as Figure 7In one embodiment, each pair of adjacent limiting channels 101 is a group, and a fastening component 300 is provided between each group of limiting channels 101, so that each fastening component 300 presses and limits the frame 20 on the adjacent limiting channel 101, thereby further simplifying the frame processing positioning fixture 10 on the basis of ensuring the reliable limiting and fixing of each frame 20.

[0050] In one embodiment, a fastening component is provided between any two adjacent limiting channels, which further improves the limiting and fixing reliability of each frame.

[0051] In one embodiment, in one set of limiting channels, a fastening component is provided between any two adjacent limiting channels; in another set of limiting channels, each pair of adjacent limiting channels forms a group, and a fastening component is provided between each group of limiting channels.

[0052] Please refer to the following: Figures 1 to 4 ,as well as Figure 7 In one embodiment, the clamping member 320 is configured to have a clearance area 301 at its distal end for protruding from the sidewall of the limiting channel 101, and the clearance area 301 is located on the side surface of the clamping member 320 near the frame 20. It can be understood that the distal end is the portion of the clamping member 320 that first protrudes from the sidewall of the limiting channel 101 during rotation, i.e., the end of the clamping member 320, which facilitates the smooth protrusion of the clamping member 320 from the sidewall of the limiting channel 101 during rotation to abut against the frame 20.

[0053] Please refer to the following: Figures 1 to 4 ,as well as Figure 7 In one embodiment, the frame processing positioning fixture 10 further includes a telescopic drive cylinder 400, which is connected to the processing support member 100. The power output end of the telescopic drive cylinder 400 is connected to the positioning member 200, so that the telescopic drive cylinder 400 drives the positioning member 200 to move along the thickness direction of the processing support member 100. Further, the telescopic drive cylinder 400 is connected to the worktable, and its power output end is offset from the processing support member 100, allowing the positioning member 200 to be movable in the thickness direction of the processing support member 100. This allows the positioning member 200 to be adjusted to abut against the end of the frame 20, thereby better achieving the limiting and fixing of the ends of the frame 20 with different shapes.

[0054] Please refer to the following: Figures 1 to 4 ,as well as Figure 7In one embodiment, the frame processing positioning fixture 10 further includes a worktable 500. Further, there are multiple processing support members 100, and the widths of the opposite side walls of the limiting channels 101 provided on the multiple processing support members 100 are different, so that the two groove walls of the limiting channel 101 of each processing support member 100 are used to abut against the side walls of the frame 20 with different widths. Further, any processing support member 100 is detachably connected to the worktable 500. For different specifications of frame 20, the limiting and fixing can be achieved by adjusting the width of the opposite side walls of the limiting channel 101, that is, by replacing the processing support member 100 on the worktable 500, the limiting and fixing of different frame 20 can be achieved.

[0055] Please refer to the following: Figures 1 to 4 ,as well as Figure 7 In one embodiment, at least two processing support members 100 are detachably connected to the worktable 500. The at least two processing support members 100 are arranged together on the same horizontal plane of the worktable 500, realizing the synchronous positioning and fixing of the frame 20 of different specifications.

[0056] Please refer to the following: Figures 5 to 6 In one embodiment, each processing support 100 has a connecting hole 102 on the side away from the worktable 500. Further, the worktable 500 has a connecting groove 501, which is coaxially arranged with the connecting hole 102. The pin 600 is respectively engaged with the connecting hole 102 and the connecting groove 501, thereby realizing a stable connection between the processing support 100 and the worktable 500.

[0057] Compared with the prior art, the present invention has at least the following advantages:

[0058] The frame processing positioning fixture 10 of this utility model provides a limiting channel 101 on one side of the processing support member 100. The two groove walls of the limiting channel 101 are used to abut against the two side walls of the frame 20. The positioning member 200 is located at either end of the limiting channel 101 and abuts against the end wall of the frame 20, thus achieving horizontal limiting and fixing of the frame 20. This, in conjunction with the telescopic rotary cylinder 310, drives the clamping member 320 to move closer to or further away from the processing support member 100 and drives the clamping member 320 to rotate. The telescopic rotary cylinder 310 also drives the clamping member 320 to move closer to the processing support member 100. The cylinder drives the clamping member 320 to move and rotate until it protrudes at least partially from the side wall of the limiting channel 101 and abuts against the side wall of the frame 20, so that the frame 20 is clamped between the processing support member 100 and the clamping member 320, thus achieving vertical limiting and fixing of the frame 20. In this way, the cylinder drives the clamping member 320 to move away from the processing support member 100 and rotate until it is separated from the side wall of the frame 20 and misaligned with the limiting channel 101. That is, when the frame 20 is placed in the limiting channel 101, the clamping member 320 is misaligned with the limiting channel 101, so that the clamping member 320 will not interfere with the limiting channel 101, improving the placement convenience of the frame 20.

[0059] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
