Technical Field

[0001] This utility model relates to the technology of handle strip processing, and in particular to a double-sided riveting fixture for chassis handle strips. Background Technology

[0002] Chassis handle strips are accessories used on computer cases, and their main function is to facilitate user operation and installation.

[0003] The chassis handle strip is composed of multiple parts, which need to be secured together using rivets or other fasteners. When using rivets, the holes in the rivets need to be enlarged to prevent the parts connected to the rivets from separating.

[0004] Traditional riveting is done manually, which is inefficient. Furthermore, when the rivet is located on the side of the assembled part, the components that make up the chassis handle strip will deviate after the expansion hole is fixed. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a double-sided riveting fixture for chassis handle strips. This fixture solves the problem that the traditional riveting method is carried out manually, which is inefficient. Furthermore, when the rivet is located on the side of the assembled part, the components that make up the chassis handle strip will deviate after the expansion hole is fixed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a double-sided riveting fixture for chassis handle strips, including a base and a workpiece placed on the processing end of the base, the base being provided with a corresponding expansion hole assembly, the expansion hole assembly including a drive cylinder and an expansion hole component connected to the output shaft of the drive cylinder;

[0007] During operation, the drive cylinder drives the expansion component to move, so that the contact part in the expansion component is inserted into the rivet hole on the workpiece, thereby expanding the volume of the rivet hole.

[0008] Furthermore, the expansion hole assembly includes two opposing positioning plates, with the expansion hole component disposed between the two positioning plates.

[0009] Furthermore, the expansion member includes an extrusion block connected to the output shaft of the drive cylinder, a displacement member movably connected to the extrusion block, and a translation member connected to the displacement member, with the contact portion located at the end of the translation member away from the displacement member.

[0010] Furthermore, the displacement component includes two first plates movably connected to the left and right sides of the extrusion block, and two second plates movably connected to the two first plates respectively. The translation component contains two plates and is respectively connected to the ends of the two second plates that are away from the first plates.

[0011] Furthermore, the displacement component also includes a positioning shaft disposed between the two first plates, and a third plate sleeved on the positioning shaft, with the end of the third plate away from the positioning shaft being movably connected to the connection between the first plate and the second plate.

[0012] Furthermore, the second plate has a cut on one side corresponding to the third plate, and the third plate is located inside the cut;

[0013] During operation, the third plate presses against the end wall of the cut, causing the second plate to move the displacement component horizontally.

[0014] Furthermore, the two opposing surfaces of the positioning plate, the extrusion block, and the translation component are provided with matching grooves or protrusions.

[0015] Furthermore, the base is provided with a support frame for supporting the drive cylinder. The support frame includes an adjustable length rod and a first plate mounted on the rod to support the drive cylinder.

[0016] Furthermore, the support frame also includes a second plate mounted on the rod, with a positioning plate located below the second plate, and the output shaft of the drive cylinder passing through the second plate to the space between the two positioning plates.

[0017] Furthermore, a reset assembly is provided between the two positioning plates. The reset assembly includes a positioning rod connecting the two positioning plates, a spring connected to the positioning rod, and the end of the spring away from the positioning rod being connected to the second plate.

[0018] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, by placing the workpiece on the processing end of the base, and then driving the abutting part of the expansion hole component to insert into the rivet hole of the workpiece through the driving cylinder, the rivet hole is enlarged and fixed to form the workpiece.

[0031] Please refer to Figure 1-4 As shown, it displays the specific structure of a preferred first embodiment of the present invention, which is a double-sided riveting fixture for a chassis handle bar, including a base 10 and a workpiece 20 placed on the processing end 11 of the base 10. The base 10 is provided with a corresponding expansion hole assembly 30 for the processing end 11. The expansion hole assembly 30 includes a drive cylinder 31 and an expansion hole component 32 connected to the output shaft of the drive cylinder 31.

[0032] During operation, the drive cylinder 31 drives the expansion member 32 to move, causing the contact part 34 in the expansion member 32 to insert into the rivet hole 21 on the workpiece 20, thereby expanding the volume of the rivet hole 21. Compared with the existing double-sided riveting fixture for chassis handles, which involves manually expanding the rivets on the workpiece by placing the assembled workpiece on a platform, this double-sided riveting fixture for chassis handles places the workpiece 20 on the processing end 11 of the base 10, and then drives the drive cylinder 31 to drive the contact part 34 of the expansion member 32 to insert into the rivet hole 21 on the workpiece 20, thereby enlarging and fixing the assembled workpiece by the rivet hole 221.

[0033] Specifically, the drive cylinder 31 can be a pneumatic cylinder, an electric push rod, or a hydraulic cylinder. The processing end 11 is a receiving groove formed on the upper end face of the base 10, and the receiving groove is divided into a first part 111 located in the middle of the upper end of the base 10 and two second parts 112 communicating with the first part 111. The inner cavity depth of the second part 112 is the same as that of the first part 111, and one end of the second part 112 extends from one side of the base 10. The first part 111 and the second part 112 are adapted to the workpiece 20 to limit the workpiece 20 placed on the base 10, so as to prevent the workpiece 20 from shifting when expanding the rivet hole 21 on the workpiece 20.

[0034] like Figure 3 As shown, for example, the expansion hole assembly 30 includes two opposing positioning plates 33, and the expansion hole component 32 is disposed between the two positioning plates 33. To prevent the expansion hole assembly 30 from shifting during use, the expansion hole assembly 30 is placed between the two opposing positioning plates 33, and the two positioning plates 33 restrict the expansion hole assembly 30 to prevent any component of the expansion hole assembly 30 from falling off during use.

[0035] like Figure 3 As shown, exemplarily, the rivet hole expansion member 32 includes a pressing block 321 connected to the output shaft of the drive cylinder 31, a displacement member 322 movably connected to the pressing block 321, and a translation member 323 connected to the displacement member 322. A contact portion 34 is located at the end of the translation member 323 away from the displacement member 322. When it is necessary to expand the rivet hole 21 on the workpiece 20, the pressing block 321 is driven by the output shaft of the drive cylinder 31 to move closer to the base 10, and this pressure on the displacement member 322 causes the displacement member 322 to move, pushing the translation member 323 to move. This allows the contact portion 34 on the translation member 323 to engage with the rivet hole 21 on the workpiece 20, thereby expanding the rivet hole 21.

[0036] like Figure 3 As shown, for example, the displacement member 322 includes two first plates 3221 movably connected to the left and right sides of the extrusion block 321, and two second plates 3222 movably connected to the two first plates 3221 respectively. The translation member 323 contains two and is respectively connected to the ends of the two second plates 3222 away from the first plates 3221. The first plate 3221 and the extrusion block 321, the second plate 3222 and the first plate 3221, and the translation member 323 and the second plate 3222 are all connected by a rod 60. The rod can be a pin. The first plate 3221 and the second plate 3222 are sleeved on the pin. When the extrusion block 321 moves toward the base 10, the first plate 3221 will move under the extrusion of the extrusion block 321 and drive the second plate 3222 to move. The second plate 3222 moves and drives the translation member 323 to move, so that the contact part 34 on the translation member 323 can mate with the rivet hole 21 on the workpiece 20, thereby expanding the rivet hole 21.

[0037] Specifically, the extrusion block 321 has first recesses 321a on both sides of one end relative to the base 10. The first plate 3221 is inserted into the first recesses 321a and is installed in the first recesses 321a via the aforementioned rod 60. The end of the first plate 3221 away from the extrusion block 321 has a second recess 3221a for accommodating the second plate 3222, and the second plate 3222 is also installed in the second recess 3221a via the rod 60.

[0038] It should be noted that the two translational members 323 include two moving strips 3231 and extension strips 3232 located at opposite ends of the two moving strips 3231. The contact part 34 is located on the opposite side of the two opposite extension strips 3232. The two sides of the moving strips 3231 relative to one end of the pressing block 321 are provided on the positioning pieces 3233. The end of the second plate 3222 away from the first plate 3221 extends to the space between the two positioning pieces 3233. The positioning pieces 3233 and the second plate 3222 are also connected by the rod 60. In addition, the positioning pieces 3233 are located on the upper edge of the opposite ends of the two moving strips 3231.

[0039] like Figure 4 As shown, exemplarily, the displacement member 322 further includes a positioning shaft 3223 disposed between the two first plates 3221, and a third plate 3224 sleeved on the positioning shaft 3223. One end of the third plate 3224 away from the positioning shaft 3223 is movably connected to the connection between the first plate 3221 and the second plate 3222. To further ensure that the translation member 323 can move under the push of the pressing block 321, so that the contact part 34 can mate with the rivet hole 21 on the workpiece 20, thereby expanding the rivet hole 21. A positioning shaft 3223 is installed on a positioning plate 33. The positioning shaft 3223 is located between the first plates 3221, and the lower part of the positioning shaft 3223 is in close contact with two opposing moving strips 3231. When the first plate 3221 moves closer to the base 10 due to the extrusion of the extrusion block 321, the second plate 3222 and the third plate 3224 will both be offset due to the extrusion. When the third plate 3224 is offset, it will extrude pressure on the second plate 3222, causing the second plate 3222 to drive the moving strip 3231 to move.

[0040] Specifically, the second plate 3222 has a cutout 3225 on one side corresponding to the third plate 3224, and the third plate 3224 is located within the cutout 3225;

[0041] During operation, the third plate 3224 presses against the end wall of the cut 3225, causing the second plate 3222 to move the displacement member 322. To ensure that the third plate 3224 can push the second plate 3222 to move after moving, a cut 3225 is opened at the connection between the second plate 3222 and the third plate 3224, so that the third plate 3224 can move against the second plate 3222 after displacement. In addition, the connection between the second plate 3222 and the third plate 3224 is located at the connection between the second plate 3222 and the first plate 3221.

[0042] like Figure 4 As shown, for example, the two opposing surfaces of the positioning plate 33, the pressing block 321, and the translation member 323 are provided with matching grooves 331 or protrusions 332. In order to prevent the pressing block 321 and the translation member 323 from shifting during movement, which would cause the contact portion 34 on the extension strip 3232 to fail to correspond to the rivet hole 21 on the workpiece 20, grooves 331 and protrusions 332 that can be matched with each other are provided on the positioning plate 33, the pressing block 321, and the translation member 323, so that the pressing block 321 and the translation member 323 can move smoothly on the positioning plate 33.

[0043] like Figure 1 As shown, for example, the base 10 is provided with a support frame 40 for supporting the drive cylinder 31. The support frame 40 includes an adjustable length rod 41 and a first plate 42 mounted on the rod 41 to support the drive cylinder 31. When placing the workpiece 20 into the processing end 11 on the base 10, the expansion hole assembly 30 can be adjusted up and down to facilitate the replacement of the workpiece 20 in the processing end 11. The expansion hole assembly 30 is set on the support frame 40 mounted on the upper end face of the base 10. There are no fewer than two rods 41 that make up the support frame 40, and they are located on both sides of the processing end 11 respectively. The first plate 42 mounted on the rod 41 is used to support the drive cylinder 31, so that the output shaft of the drive cylinder 31 corresponds to the upper part of the processing end 11.

[0044] like Figure 4 As shown, for example, the support frame 40 also includes a second plate 43 disposed on the rod 41, a positioning plate 33 located below the second plate 43, and the output shaft of the drive cylinder 31 passes through the second plate 43 to the space between the two positioning plates 33.

[0045] A reset assembly 50 is also provided between the two positioning plates 33. The reset assembly 50 includes a positioning rod 51 connecting the two positioning plates 33, and a spring 52 is connected to the positioning rod 51. The end of the spring 52 away from the positioning rod 51 is connected to the second plate 43. The spring 52 enables the expansion hole assembly 30, which moves towards the base 10 under the push of the output shaft of the drive cylinder 31, to be reset more quickly in the reset state of the drive cylinder 31, so as to facilitate the operator to change the workpiece on the base 10.

[0046] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
