Description

Technical Field

[0001] This utility model relates to the technical field of metal parts processing, specifically a metal parts riveting machine with a positioning mechanism. Background Technology

[0002] In modern industrial production, the joining process of metal parts is crucial. As a common and efficient joining method, riveting is widely used in many fields, such as electronic equipment manufacturing, automotive parts production, and aerospace industry. As a key piece of equipment for realizing the riveting process, the performance of the riveting machine directly affects the riveting quality and production efficiency.

[0003] There are many types of existing metal riveting machines. However, in the production of metal chassis, sheet metal is riveted to facilitate assembly and fix it into a metal chassis. During riveting, the sheet metal may slide, which greatly reduces the efficiency of metal chassis production. To solve the above problem, a riveting machine for producing metal chassis can be described in the prior art (Chinese patent application number CN202120878366.4, application date 2021-04-27). This riveting machine uses a second telescopic spring to push the clamping plate, so that the clamping plate and the base plate clamp the sheet metal. A first telescopic spring pulls the sliding plate to tighten the sheet metal. The first sliding groove and the slider can easily move the movable plate left and right. The fixed rod and the support plate can provide support for the sheet metal, which is convenient for riveting. The fixed frame and the machine head can perform the riveting process on the sheet metal.

[0004] Although the above-mentioned device can effectively avoid the problem of misalignment during the riveting process, it still has certain limitations in practical applications. Specifically, before processing the metal parts, it is necessary not only to complete the positioning operation, but also to clean the dust on the surface of the metal parts. However, the device has failed to solve these two problems well.

[0005] Therefore, we proposed that a metal riveting machine with a positioning mechanism can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a metal part riveting machine with a positioning mechanism, so as to solve the problem mentioned in the background art that the current riveting machines on the market not only need to complete the positioning operation before processing the metal parts, but also need to clean the dust on the surface of the metal parts.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a metal riveting machine with a positioning mechanism, comprising a riveting machine and two sets of pneumatic control switches disposed on one side of the front end of the riveting machine. One set of pneumatic control switches controls the riveting process of the riveting machine, and the other set of pneumatic control switches controls the operation of the air pump inside the riveting machine. A worktable is installed on the surface of the riveting machine, and a driving mechanism is disposed at the bottom of the worktable. The driving mechanism enables relative movement of positioning plates disposed on both sides of the top of the worktable, and can perform limiting and fitting treatment on the metal parts on the top of the worktable. An air jet mechanism is also disposed on one side of the driving mechanism, and the air jet mechanism can perform air jet cleaning treatment on the metal parts after positioning on the surface of the worktable.

[0008] As a preferred technical solution of this application, the driving mechanism includes a fixed rigid pipe connected to the top of the gas pipeline. A square groove is opened inside the fixed rigid pipe. A piston is fitted to the bottom of the fixed rigid pipe. The upper inner wall of the piston is spirally connected to the bottom of the spiral rod. The top of the spiral rod is fixed to the center of the turntable. A set of turntables is rotatably connected to both sides of the top edge of the turntable. The other end of the turntable is rotatably connected to one end of a connecting rod. The upper outer side of the connecting rod is fixed to the outer side of the positioning plate.

[0009] As a preferred technical solution of this application, the bottom end of the fixed rigid tube is fixed inside the workbench, and the two sets of positioning plates form a relative sliding structure with the inside of the workbench through the moving rod.

[0010] As a preferred technical solution of this application, the piston component includes a connecting spring fixed inside the fixed rigid tube, and the top of the connecting spring is fixed to the bottom of the piston component. A spiral sleeve is also fixed at the upper end of the piston component, and the outer side of the spiral sleeve is spirally connected to the bottom end of the spiral rod.

[0011] As a preferred technical solution of this application, the bottom position of the turntable is rotatably disposed inside the worktable, and the turntable forms a rotating structure with the interior of the worktable through a helical rod.

[0012] As a preferred technical solution of this application, the jet mechanism includes a connecting pipe connected to one side of the lower end of the fixed rigid pipe, and a conical block is slidably disposed inside the connecting pipe. The outer end of the conical block is connected to the inside of the connecting pipe through a return spring, and the outer end of the connecting pipe is connected to the jet nozzle.

[0013] As a preferred technical solution of this application, the outer end of the jet nozzle is located on the top surface of the worktable, and the elastic force of the reset spring is greater than that of the connecting spring.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This metal part riveting machine with a positioning mechanism is equipped with a drive mechanism. The drive mechanism enables gas to be delivered into the interior of the fixed rigid tube, thereby causing the piston to drive the turntable to rotate during movement. The rotation of the turntable can drive the two sets of positioning plates to move, thereby positioning the metal part. In addition, the air jet mechanism enables gas to be jetted through the air jet nozzle, thereby cleaning the metal part. The specific details are as follows:

[0015] 1. A fixed rigid tube is set up. The piston inside the fixed rigid tube slides in the square groove with gas, which can be transported through the connecting pipe. The connecting pipe can then be transported through the conical block, and the gas can be sprayed through the jet nozzle to clean the metal parts, which facilitates subsequent work.

[0016] 2. A piston component is provided, which slides inside the square groove. When the piston component moves, it drives the spiral rod connected by the spiral sleeve to rotate. The spiral rod drives the turntable to rotate. The top of the turntable drives the connecting rod connected by the rotation to rotate. The connecting rod drives the moving rod and the positioning plate to move inside the worktable, thereby positioning the metal parts and facilitating the subsequent riveting process.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: a metal part riveting machine with a positioning mechanism.

[0026] Example 1: To address the issue that current riveting machines on the market require not only positioning but also cleaning of dust from the metal surface before processing, the following solution can be found in the attached diagram. Figure 1 -Appendix Figure 3 and attached Figure 6 A worktable 3 is mounted on the surface of the riveting machine 1. A drive mechanism is located at the bottom of the worktable 3. The drive mechanism allows the positioning plates 12 on both sides of the top of the worktable 3 to move relative to each other, and can limit and fit the metal parts on the top of the worktable 3. An air jet mechanism is also provided on one side of the drive mechanism. The air jet mechanism can perform air jet cleaning on the metal parts after positioning on the surface of the worktable 3. The air jet mechanism includes a connecting pipe 13 connected to the lower end of the fixed rigid pipe 5. A conical block 14 is slidably installed inside the connecting pipe 13. The outer end of the conical block 14 is connected to the inside of the connecting pipe 13 through a return spring 15. The outer end of the connecting pipe 13 is connected to the air jet 16. The outer end of the air jet 16 corresponds to the top surface of the worktable 3, and the elastic force of the return spring 15 is greater than the elastic force of the connecting spring 61.

[0027] After the metal part is placed on the top of the workbench 3, a set of pneumatic control switches 2 is activated, which activates the pump inside the riveting machine 1, allowing gas to be delivered into the air supply pipe 4. This causes the piston 6 inside the fixed rigid pipe 5 to move. When the piston 6 stops moving, gas is delivered to one end of the connecting pipe 13, which compresses the conical block 14 at one end of the connecting pipe 13. The conical block 14 then moves inside the connecting pipe 13 and can be moved by the return spring 15. At this time, gas is delivered through the connecting pipe 13. Since one end of the connecting pipe 13 is connected to the air nozzle 16, the air nozzle 16 can perform air cleaning on the surface of the metal part. After cleaning, the metal part is riveted by another set of pneumatic control switches 2.

[0028] Example 2: For positioning of metal parts, please refer to the attached document. Figure 1 -Appendix Figure 5 The system includes a riveting machine 1 and two sets of pneumatic control switches 2 on one side of the front end of the riveting machine 1. One set of pneumatic control switches 2 controls the riveting process of the riveting machine 1, and the other set of pneumatic control switches 2 controls the operation of the air pump inside the riveting machine 1. The drive mechanism includes a fixed rigid pipe 5 connected to the top end of an air supply pipe 4. A square groove 7 is opened inside the fixed rigid pipe 5. A piston 6 is fitted to the bottom end of the fixed rigid pipe 5. The upper inner wall of the piston 6 is spirally connected to the bottom end of a spiral rod 8. The top end of the spiral rod 8 is fixed to the center of a turntable 9. A set of turntables 9 are rotatably connected to both sides of the top edge of the turntable 9. The other end of the turntable 9 is rotatably connected to a connecting rod 10. The upper outer end of the connecting rod 10 is fixed to the outer side of the positioning plate 12; the bottom end of the fixed rigid tube 5 is fixed inside the worktable 3, and the two sets of positioning plates 12 form a relative sliding structure with the interior of the worktable 3 through the moving rod 11; the piston 6 includes a connecting spring 61 fixed inside the fixed rigid tube 5, and the top of the connecting spring 61 is fixed to the bottom of the piston 6. A spiral sleeve 62 is also fixed at the upper end of the piston 6, and the outer side of the spiral sleeve 62 is spirally connected to the interior of the bottom end of the spiral rod 8; the bottom of the turntable 9 is rotatably set inside the worktable 3, and the turntable 9 forms a rotating structure with the interior of the worktable 3 through the spiral rod 8.

[0029] When it is necessary to limit the metal parts on the top of the workbench 3, a set of pneumatic control switches 2 can be pressed. The pneumatic control switches 2 deliver gas into the air supply pipe 4, which in turn delivers the gas into the fixed rigid pipe 5. This causes the piston 6 to move within the fixed rigid pipe 5 through the square groove 7. Furthermore, the movement of the piston 6 within the square groove 7 causes it to move via the connecting spring 61. This causes the screw sleeve 62 fixed to the top of the piston 6 to rotate, which in turn drives the screw rod 8, which is also rotated. The rotation of the turntable 9 causes the connecting rods 10 at two points on the top edge of the turntable 9 to move the moving rods 11, which in turn causes the positioning plates 12 to move relative to each other. At this time, the positioning plates 12 can limit the metal parts. The metal parts are then riveted by another set of pneumatic control switches 2. After the riveting is completed, the pneumatic control switches 2 are raised. At this time, the pneumatic control switches 2 will control the air pump to recover the gas. The piston 6 will then be reset, which will allow the two sets of positioning plates 12 to loosen the metal parts, making it easier to handle the material later.
