Technical Field

[0001] The present invention relates to the technical field of aluminum alloy processing, and in particular to a fastening mechanism for aluminum alloy lightweight processing equipment and a use method thereof. Background Art

[0002] Aluminum alloy is an alloy material composed of aluminum as the base and other elements. It is a light metal material. Aluminum alloy material not only has strong rigidity, but also has good casting performance and plastic processing performance, good electrical and thermal conductivity, good corrosion resistance and weldability. It can be used as a structural material and has a wide range of applications in aerospace, aviation, transportation, construction, electromechanical, light chemicals and daily necessities.

[0003] Aluminum alloys have different applications in different equipment. When used in some electronic products, grooves are usually cut on the surface of the sheet. Some grooves will not penetrate, while some grooves may penetrate. The traditional processing method is to place it on a processing table for operation, or to clamp it with a bench vise for operation. When operating on the processing table, it is impossible to process the through grooves on the surface. When clamping with a bench vise, the bench vise is required to clamp them separately, and the clamping of the bench vise may cause obvious imprints on the surface of the sheet. Therefore, it is necessary to design a fastening mechanism for aluminum alloy lightweight processing equipment. Summary of the invention

[0004] The present invention aims at the deficiencies in the prior art and provides the following technical solutions:

[0005] A fastening mechanism for aluminum alloy lightweight processing equipment comprises: a plurality of pillars, adjustment tubes nested outside the pillars, and a driving assembly for driving at least one of the adjustment tubes to rotate along the axial direction of the pillars.

[0006] Specifically, the two ends of the adjusting tube have double threads in opposite directions, and a gear is integrally formed at the intersection of the threads of the adjusting tube. The outer sides of the gears of several adjusting tubes are meshed with synchronous belts for synchronous rotation. The two ends of the adjusting tube are respectively threadedly connected to a press frame. When the driving assembly drives the adjusting tube to rotate, the synchronous belt drives all the gears to rotate synchronously to drive the press frames at both ends to approach each other until the material plate is clamped.

[0007] As an improvement of the above technical solution, a bottom plate is integrally formed at the bottom of the pillar, a mounting frame is fixed to the upper end surface of the bottom plate, and the mounting frame is used to install processing equipment for the material plate.

[0008] As an improvement of the above technical solution, the driving assembly includes a positioning frame, bevel gear 1 and bevel gear 2 that mesh with each other, a hand crank is fixed to one end of the bevel gear 1, a through groove is opened at the upper end of the positioning frame, the hand crank is inserted into the through groove, a positioning ring 1 is threadedly connected to the inner side of the through groove, the hand crank is inserted into the interior of the positioning ring 1, the bevel gear 2 is integrally formed with the lower end of the adjusting tube, and when the positioning ring 1 is tightened inward, the hand crank is squeezed to form a fixed state.

[0009] As an improvement of the above technical solution, the adjusting tube includes two groups of threaded tubes and two groups of extension tubes. The two groups of threaded tubes are coaxially fixed, and the thread directions of the two groups of threaded tubes are opposite. The gear fixing sleeve is arranged at the connection of the threaded tubes, and the extension tube is coaxially fixed to the other end of the threaded tube.

[0010] As an improvement of the above technical solution, the pressing frame includes positioning rings II and tracks, the number of which is twice that of the pillars. The positioning rings II and the tracks are divided into two groups in equal amounts. A track is fixed between two adjacent positioning rings II in each group. The two groups of positioning rings II are respectively threadedly connected to the two ends of the adjusting tube, and a pressing part is detachably fixed on the inner side of the track.

[0011] As an improvement of the above technical solution, an extension rod is integrally formed on the upper end surface of the pressing piece, and the other end of the extension rod is inserted into the other side of the track and threadedly connected with a nut.

[0012] As an improvement of the above technical solution, the support includes a mounting tube and an insertion rod, one end of the mounting tube is provided with a threaded groove, one end of the insertion rod is integrally formed with a threaded rod, and the threaded rod is threadedly inserted into the threaded groove.

[0013] As an improvement of the above technical solution, when the threaded rod is fully inserted into the threaded groove, a ring-shaped side cavity is separated from the mounting tube and the insertion rod, a protrusion is integrally formed on the inner side of the gear, and the protrusion is inserted into the side cavity, the upper end of the insertion rod is threadedly connected to a top plate, and the mounting frame is fixed to the lower end surface of the top plate.

[0014] As an improvement of the above technical solution, the protrusion is a bearing, the bearing is fixed to the inner wall of the regulating tube, and the bearing is located in the middle of the regulating tube.

[0015] The method for using the fastening mechanism for aluminum alloy lightweight processing equipment is applied to the fastening mechanism for aluminum alloy lightweight processing equipment as described in the above scheme, and comprises the following steps:

[0016] S10: Slide the adjustment tube over the mounting tube and screw in the insertion rod to fix it.

[0017] S20: Install the top plate and install the processing equipment on the inner side of the mounting frame.

[0018] S30: placing the sheet material on the pressing rack located below, controlling the driving assembly to drive the gear to rotate until the two pressing racks clamp the sheet material, and then performing the processing operation.

[0019] Beneficial effects of the present invention:

[0020] The setting of the press frame forms a clamping assembly that moves synchronously up and down, so there is no need for additional clamping through a bench vise during processing, and the clamping paths of the four corners are the same, and the plate will not be twisted due to different clamping heights. While ensuring stable clamping, the middle position of the plate can also be kept in a suspended state, so that subsequent processing operations can be performed, which facilitates the opening of through grooves on the surface of the plate.

DETAILED DESCRIPTION

[0028] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0029] Aluminum alloys have different applications in different equipment. When used in some electronic products, slots are usually cut on the surface of the sheet. Some slots will not penetrate, while others may penetrate. The traditional processing method is to place it on a processing table or clamp it with a bench vise. When operating on a processing table, it is impossible to process the surface through the slot. When clamping with a bench vise, the bench vise needs to be clamped separately, and the clamping of the bench vise may cause obvious embossing on the surface of the sheet.

[0030] In order to solve the above problems, the following embodiments are provided:

[0031] Embodiment 1

[0032] The fastening mechanism for aluminum alloy lightweight processing equipment comprises: a plurality of pillars 11, an adjusting tube 20 nested outside the pillars 11, and a driving assembly for driving at least one adjusting tube 20 to rotate along the axial direction of the pillar 11.

[0033] Specifically, the two ends of the adjusting tube 20 have double threads in opposite directions, and a gear 23 is integrally formed at the intersection of the threads of the adjusting tube 20. The outer sides of the gears 23 of several adjusting tubes 20 are meshed with a synchronous belt 24 for synchronous rotation. The two ends of the adjusting tube 20 are respectively threadedly connected to a press frame 25. When the driving assembly drives the adjusting tube 20 to rotate, the synchronous belt 24 drives all the gears 23 to rotate synchronously to drive the press frames 25 at both ends to approach each other until the material plate is clamped.

[0034] The press frame 25 is driven to move by the rotation of the double-threaded adjustment tube 20, and its structure is similar to that of the screw track. The gear 23 and the timing belt 24 form a synchronous rotation structure, and the cooperation of the double threads forms a state in which the two press frames 25 move toward each other until the two press frames 25 clamp the sheet. This design requires the thickness of the sheet to be greater than the thickness of the gear 23. Therefore, in order to ensure the strength of the structure, the material of the gear 23 needs to be as thin as possible, and a higher strength material can be used.

[0035] In one embodiment, see Figure 1 A bottom plate 10 is integrally formed at the bottom of the support 11, and a mounting frame 12 is fixed to the upper end surface of the bottom plate 10. The mounting frame 12 is used to install processing equipment for the material plate.

[0036] The bottom plate 10 is used to provide positioning and support for the pillars 11, and a mounting frame 12 is provided on the top to install processing equipment, usually a drilling machine, a grinder and other auxiliary processing equipment.

[0037] In one embodiment, see Figures 1 to 3 The driving assembly includes a positioning frame 13, a bevel gear 131 and a bevel gear 221 that mesh with each other, a hand crank 132 is fixed to one end of the bevel gear 131, a through groove is opened at the upper end of the positioning frame 13, the hand crank 132 is inserted into the through groove, a positioning ring 133 is threadedly connected to the inner side of the through groove, the hand crank 132 is inserted into the inside of the positioning ring 133, the bevel gear 221 and the lower end of the adjusting tube 20 are integrally formed, and when the positioning ring 133 is tightened inwardly, the hand crank 132 is squeezed to form a fixed state.

[0038] A rotating transmission structure is formed by the meshing between the bevel gear 131 and the bevel gear 221. When the bevel gear 131 rotates, the bevel gear 221 rotates accordingly, thereby driving the adjusting tube 20 to rotate. The rotation of the adjusting tube 20 will drive the two pressing frames 25 to rotate, thereby clamping the entire material plate.

[0039] The solution adopted in this embodiment is a hand crank 132, which drives the bevel gear 131 to rotate by rotating the hand crank 132. In addition to using the hand crank 132, any device that can drive the bevel gear 131 to rotate can be used, such as adding a motor.

[0040] Unlike the electric one, the hand crank 132 needs to be positioned after the hand crank 132 is shaken, so a positioning ring 133 is provided. When the adjustment is completed, the positioning ring 133 can be squeezed into the interior by tightening the positioning ring 133 inward. After the positioning ring 133 is squeezed in, the rod body of the hand crank 132 is squeezed, thereby forming a fixed state.

[0041] In one embodiment, see Figure 1 and Figure 2 The adjusting tube 20 includes two groups of threaded tubes 21 and two groups of extension tubes 22. The two groups of threaded tubes 21 are fixed coaxially, and the thread directions of the two groups of threaded tubes 21 are opposite. The gear 23 is fixedly sleeved at the connection of the threaded tubes 21, and the extension tube 22 is coaxially fixed to the other end of the threaded tube 21.

[0042] The regulating tube 20 is formed by integrally molding four rod bodies, so that it can be processed more conveniently by means of a mold or the like.

[0043] To further improve the solution of the press stand 25, please refer to Figures 1 to 6The press frame 25 includes positioning rings 251 and rails 252, which are twice the number of the pillars 11. The positioning rings 251 and rails 252 are divided into two groups in equal amounts. A rail 252 is fixed between two adjacent positioning rings 251 in each group. The two groups of positioning rings 251 are respectively threadedly connected to the two ends of the adjusting tube 20, and a pressing piece 26 is detachably fixed on the inner side of the rail 252.

[0044] A rectangular frame structure is formed by the cooperation between the positioning ring 251 and the track 252, so that when the four adjusting tubes 20 are passed through, a threaded driven movement state can be formed, and the four corners can move synchronously, forming the function of synchronous drive of the entire pressing frame 25, and different pressing parts 26 can be installed according to different sheets to clamp the sheets, as long as the sheets can be fixed on the track 252.

[0045] In one embodiment, see Figure 2 and Figure 6 An extension rod 261 is integrally formed on the upper end surface of the pressing piece 26 , and the other end of the extension rod 261 is inserted into the other side of the track 252 and is threadedly connected with a nut 262 .

[0046] The clamping fixing method is formed by the cooperation between the nut 262 and the extension rod 261. When processing different types of plates, workpieces of different sizes can be used, and positioning methods other than those described in this embodiment can also be used for fixing.

[0047] To facilitate the later disassembly of the entire scheme, please refer to Figures 1 to 6 The support 11 includes a mounting tube 111 and an insert rod 112. A threaded groove is formed at one end of the mounting tube 111. A threaded rod 113 is integrally formed at one end of the insert rod 112. The threaded rod 113 is threadedly inserted into the threaded groove.

[0048] The support 11 is set to a split structure state, so that when it is subsequently disassembled, it is only necessary to remove the entire support 11. In order to facilitate the positioning of the adjustment tube 20, please refer to Figures 1 to 6 When the threaded rod 113 is fully inserted into the threaded groove, a ring-shaped side cavity 114 is separated between the mounting tube 111 and the insertion rod 112. A protrusion 231 is integrally formed on the inner side of the gear 23, and the protrusion 231 is inserted into the side cavity 114. The upper end of the insertion rod 112 is threadedly connected to the top plate, and the mounting frame 12 is fixed to the lower end surface of the top plate.

[0049] That is, the protrusion 231 is positioned by being snapped into the side cavity 114. This positioning method can facilitate subsequent disassembly work while ensuring the stability of the structural parts. In order to facilitate the smooth rotation of the protrusion 231, the protrusion 231 can be a bearing, which is fixed to the inner wall of the adjusting tube 20 and is located in the middle of the adjusting tube 20.

[0050] This design allows the entire adjusting tube 20 to rotate more smoothly, and there is no need to consider the tightness of the fixation between the insertion rod 112 and the mounting tube 111.

[0051] Embodiment 2

[0052] In order to cooperate with the first embodiment, a method for using a fastening mechanism for aluminum alloy lightweight processing equipment is also provided, which is applied to the fastening mechanism for aluminum alloy lightweight processing equipment in the first embodiment, and includes the following steps:

[0053] S10: Insert the adjustment tube 20 onto the mounting tube 111 and screw the insertion rod 112 into the mounting tube 111 to fix the tube.

[0054] Step S10 is for installing the entire support structure. After completing step S10, relevant processing equipment needs to be installed, so step S20 is executed.

[0055] S20: Install the top plate and install the processing equipment on the inner side of the mounting frame 12.

[0056] When all processing equipment is completed, step S30 can be executed to perform actual processing operations.

[0057] S30: Place the sheet material on the pressing rack 25 located below, control the driving assembly to drive the gear 23 to rotate, and perform the processing operation after the two pressing racks 25 clamp the sheet material.

[0058] When the two pressing frames 25 press the material sheet, it is determined that the material sheet has been positioned and fixed. At this time, the rotation can be stopped and subsequent processing operations can be performed. After the processing is completed, the reverse operation is performed again to separate the two pressing frames 25 to remove the entire material sheet.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them. Anyone familiar with the technology can modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
