Description

Technical Field

[0001] The utility model relates to the field of parts processing devices, in particular to a rapid auxiliary positioning device and a rapid auxiliary positioning fixture structure. Background Art

[0002] In the production of mobile phones, the U-shaped opening of the mobile phone frame blank needs to be placed in the CNC sub-jig for further processing. Currently, most people use the manual placement method to place the blank.

[0003] However, the U-shaped opening dimensions of mobile phone frame blanks often vary. These dimensional deviations can prevent three sides of the blank from contacting the sub-clamp's reference surface, reducing the yield rate for subsequent processing. Furthermore, during manual material placement, the operator must maintain constant pressure on the product while the sub-clamp is tightened to ensure accurate positioning, posing a safety hazard. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a quick auxiliary positioning device and a quick auxiliary positioning fixture structure, which have the advantages of being able to perform three-sided positioning of mobile phone frame blanks and reduce manual operations.

[0005] A rapid auxiliary positioning device comprises a positioning cylinder, a positioning drive block and a positioning push block; the positioning drive block is connected to the output end of the positioning cylinder; the positioning push block comprises a main push block and two side push blocks, and the main push block and the two side push blocks are telescopically arranged on the positioning drive block; the main push block is arranged at the front end of the positioning drive block, and the side push blocks are arranged on both sides of the positioning drive block.

[0006] The rapid auxiliary positioning device described in the utility model simultaneously presses and positions the three sides of the mobile phone frame blank through the main pushing block and the side pushing block, thereby achieving the effect of three-side positioning, and is driven by the positioning cylinder, which reduces manual operation and reduces the risk of injury to the operator.

[0007] Furthermore, the positioning push block also includes a pushing block base plate, the main pushing block is arranged on the top surface of the pushing block base plate, a accommodating bin is provided in the pushing block base plate, and a driving port connecting the accommodating bin and the outside is provided at the bottom of the pushing block base plate, and the positioning driving block can be movably inserted into the accommodating bin through the driving port.

[0008] Furthermore, guide openings are respectively provided on both sides of the bottom plate of the pushing block, and the guide openings cooperate with the side pushing block, and the side pushing block can be slidably inserted into the guide openings; the side pushing block is connected to the positioning driving block through a connecting rod, and one end of the connecting rod is rotatably connected to the side pushing block, and the other end is rotatably connected to the positioning driving block.

[0009] Because the side pushers and positioning drive block are connected by a connecting rod, they work in tandem. When the main pusher pushes the middle of the phone frame blank, the side pushers, driven by the connecting rod, simultaneously push both sides of the phone frame blank, achieving three-sided positioning.

[0010] Furthermore, the length of the connecting rod is greater than the minimum distance between the side push block and the positioning drive block. When the main push block is away from the positioning drive block, the connection between the connecting rod and the side push block is closer to the main push block than the connection between the connecting rod and the positioning drive block.

[0011] When the main pushing block approaches the positioning driving block, the distance between the connection between the connecting rod and the positioning driving block and the main pushing block is reduced, thereby increasing the distance between the side pushing block and the positioning driving block.

[0012] Furthermore, a limit block for limiting the range of movement of the positioning drive block is provided in the accommodating compartment.

[0013] The limit block can limit the range of movement of the positioning drive block and prevent the positioning drive block from falling off from the positioning push block.

[0014] Furthermore, the main pushing block is connected to the positioning driving block via a second elastic mechanism. The second elastic mechanism can help the main pushing block to reset.

[0015] A quick auxiliary positioning fixture structure is characterized by comprising: the aforementioned quick auxiliary positioning device and a sub-clamp, wherein the sub-clamp is used to clamp a mobile phone frame blank.

[0016] Furthermore, the sub-clamp includes a clamp base and a clamp seat; the clamp seat is arranged on the clamp base; and a U-shaped frame groove is provided on the side of the clamp seat. The U-shaped frame groove can better accommodate the mobile phone frame blank.

[0017] Furthermore, the fixture seat is provided with a plurality of pressing blocks, which are arranged on the fixture seat along the U-shaped frame groove via a first elastic mechanism, with a portion of the pressing blocks extending above and outside the U-shaped frame groove. The pressing blocks can fix the mobile phone frame blank in the U-shaped frame groove.

[0025] Example

[0026] See also Figures 1 to 3 The embodiment of the present application provides a rapid auxiliary positioning fixture structure for quickly positioning the outer side of a mobile phone frame blank in a sub-clamp 2 on three sides. The rapid auxiliary positioning fixture structure includes a rapid auxiliary positioning device 1 and a sub-clamp 2; the sub-clamp 2 is used to clamp the mobile phone frame blank. When in use, the sub-clamp 2 module is located next to the rapid auxiliary positioning device 1; the rapid auxiliary positioning device 1 is used to make the mobile phone frame blank close to the reference surface of the sub-clamp 2, thereby improving the subsequent product processing qualification rate.

[0027] The sub-clamp 2 includes a clamp base plate 21 and a clamp seat 22, and the clamp seat 22 is arranged on the clamp base plate 21. A U-shaped frame groove 22b for placing the mobile phone frame blank is provided on the side of the clamp seat 22; in some embodiments, U-shaped frame grooves 22b are symmetrically provided on both sides of the clamp seat 22. Furthermore, a plurality of pressing blocks 22a are provided on the clamp seat 22; the pressing blocks 22a are arranged on the clamp seat 22 along the U-shaped frame groove 22b through a first elastic mechanism, and a part of the pressing blocks 22a extends to the upper outside of the U-shaped frame groove 22b. When the mobile phone frame blank is placed in the U-shaped frame groove 22b, the pressing blocks 22a press the mobile phone frame blank into the U-shaped frame groove 22b through the elastic force provided by the first elastic mechanism.

[0028] The rapid auxiliary positioning device 1 includes a positioning cylinder 10, a positioning drive block 11, and a positioning push block 12. The positioning drive block 11 is connected to the output end of the positioning cylinder 10. The positioning push block 12 includes a main push block 12a and two side push blocks 12b. The main push block 12a and the two side push blocks 12b are retractably mounted on the positioning drive block 11. The main push block 12a is located at the front end of the positioning drive block 11, and the side push blocks 12b are located on both sides of the positioning drive block 11.

[0029] When the quick auxiliary positioning device 1 is in operation, the sub-clamp 2 is placed next to the quick auxiliary positioning device 1, with the positioning drive block 11 facing the U-shaped frame groove. The mobile phone frame blank is then placed into the U-shaped frame groove 22b. The positioning cylinder 10 is then activated, and the positioning cylinder 10 pushes the positioning drive block 11 to move. The main push block 12a on the positioning drive block 11 pushes the middle mobile phone frame blank to make it fit tightly against the center of the U-shaped frame groove 22b, while the side push blocks 12b push the mobile phone frame blank on both sides to make them fit tightly against the sides of the U-shaped frame groove 22b.

[0030] Furthermore, the positioning push block 12 also includes a push block base plate 121. The main push block 12a is disposed on the top surface of the push block base plate 121. A storage compartment 121a is disposed in the push block base plate 121. A drive opening is disposed at the bottom of the push block base plate 121, connecting the storage compartment 121a with the outside. The positioning drive block 11 can be movably inserted into the storage compartment 121a through the drive opening. Furthermore, guide openings 121b are disposed on both sides of the push block base plate 121. The guide openings 121b cooperate with the side push blocks 12b, and the side push blocks 12b can be slidably inserted into the guide openings 121b. Furthermore, the side push blocks 12b are connected to the positioning drive block 11 via a connecting rod 12c. One end of the connecting rod 12c is rotatably connected to the side push block 12b, and the other end is rotatably connected to the positioning drive block 11.

[0031] When the positioning cylinder 10 pushes the main positioning drive block 11 close to the U-shaped frame groove 22b, the main pushing block 12a on the positioning drive block 11 pushes the middle mobile phone frame blank so that it is tightly attached to the middle of the U-shaped frame groove 22b, and at the same time the distance between the main pushing block 12a and the positioning drive block 11 is reduced; thereby causing the side pushing blocks 12b to extend to both sides, pushing the mobile phone frame blanks on both sides so that they are tightly attached to both sides of the U-shaped frame groove 22b.

[0032] Furthermore, the length of the connecting rod 12c is greater than the minimum distance between the side thrust block 12b and the positioning drive block 11. When the main thrust block 12a is away from the positioning drive block 11, the connection between the connecting rod 12c and the side thrust block 12b is closer to the main thrust block 12a than the connection between the connecting rod 12c and the positioning drive block 11. Therefore, when the main thrust block 12a approaches the positioning drive block 11, the distance between the connection between the connecting rod 12c and the positioning drive block 11 and the main thrust block 12a decreases, causing the side thrust block 12b to increase its distance from the positioning drive block 11 under the action of the connecting rod 12c.

[0033] In some embodiments, a limit block 121c is further provided in the accommodating chamber 121a for limiting the range of movement of the positioning driving block 11, so that the positioning driving block 11 can only move between the limit block 121c and the main pushing block 12a.

[0034] In some embodiments, the main push block 12a is connected to the positioning drive block 11 through a second elastic mechanism. When the positioning cylinder 10 pushes the positioning drive block 11 so that the push block base plate 121 approaches the mobile phone frame blank, the main push block 12a contacts the mobile phone frame blank and is subjected to force, causing the second elastic mechanism to compress. At the same time, the distance between the side push block 12b and the positioning drive block 11 increases, pushing the mobile phone frame blank on both sides; subsequently, when the positioning cylinder 10 pulls the positioning drive block 11 so that the push block base plate 121 moves away from the mobile phone frame blank, the main push block 12a is reset under the action of the second elastic mechanism, while driving the side push block 12b to retract. The distance between the side push block 12b and the positioning drive block 11 is reduced, and the two side push blocks 12b are automatically reset, achieving the effect of simultaneously resetting the main push block 12a and the side push block 12b.

[0035] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
