Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a device and production line for pressing and riveting products. Background Technology

[0002] In modern mechanical manufacturing, especially in the production of precision components such as engines and hydraulic pumps, it is often necessary to press cylinder liners into pre-fabricated process holes to enhance their wear resistance or meet specific functional requirements. To ensure the cylinder liner is firmly fixed in the hole and prevent it from loosening or rotating during subsequent use, a riveting process is usually performed on its opening after pressing in the cylinder liner. This process involves localized plastic deformation around the product's opening to lock the cylinder liner in place.

[0003] Currently, for the aforementioned "first press-fit, then rivet" process, the mainstream production method is a step-by-step operation. First, operators use a dedicated profile pressing head for pressing the cylinder liner to clamp and position the product for the first time, completing the pressing-fit. Then, the pressing head is manually removed and replaced with a dedicated riveting head. Afterward, the operator needs to clamp and position the pressed product a second time before proceeding with the riveting process.

[0004] However, this traditional operating mode has many inherent drawbacks: First, it has low production efficiency. The two independent clamping processes and the manual mold and tool changes in between consume a lot of time, hindering the improvement of production cycle time. Second, positioning accuracy is difficult to guarantee. After the product is clamped twice, there is an inevitable repeated positioning error, which may cause the riveting position to be misaligned with the cylinder liner after pressing, affecting the riveting quality and even causing the product to be scrapped. Third, labor costs are high and the labor intensity is high. Frequent changes of press heads and clamping operations place high demands on the skills and physical strength of the operators, and also increase the risk of human error. Finally, this discrete process arrangement is not conducive to achieving automated and intelligent production and is difficult to integrate into modern continuous production lines.

[0005] Therefore, there is an urgent need for a dedicated automated device that can integrate pressing and riveting functions, realize automatic switching of pressing heads, and avoid secondary clamping of products, so as to solve the prominent problems of low efficiency, poor accuracy, and reliance on manual labor in the existing technology.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0021] Example 1, refer to Figures 1-6 As shown, this utility model discloses a device for pressing and riveting products, comprising, Rack 1; The material loading assembly 2 includes a base 21, a mounting plate 22, positioning pins 23, a material loading block 24, and a first drive source 25. The base 21 is slidably disposed in the cabinet 1. The first drive source 25 is mounted on the cabinet 1 to drive the base 21 to slide. A mounting plate 22 is vertically connected to the base 21. A positioning plate 26 is parallelly connected to the mounting plate 22. Two positioning pins 23 are vertically disposed on the positioning plate 26. A material loading block 24 located below the two positioning pins 23 is parallelly connected to the positioning plate 26. The clamping assembly 3 includes a second drive source 31 and a clamping arm 32. The second drive source 31 is vertically connected to the mounting plate 22 and located on one side of the positioning plate 26. The output end of the second drive source 31 is vertically connected to the clamping arm 32. The pressing and riveting assembly 4 includes a mounting frame 41, a third drive source 42, a fourth drive source 43, a pressing head 44, and a riveting head 45. The mounting frame 41 is disposed in the cabinet 1. The third drive source 42 is vertically disposed on the mounting frame 41 and located above the material loading assembly 2. A connecting plate 46 is disposed at the output end of the third drive source 42. A sliding plate 47 is slidably connected to the connecting plate 46. The fourth drive source 43 is disposed on one side of the connecting plate 46 to drive the sliding plate 47 to slide. The sliding plate 47 is vertically disposed with pressing heads 44 and riveting heads 45 arranged at intervals in its sliding direction. The clamping and guiding assembly 5 includes a fifth drive source 51 and a guide pin 52. The fifth drive source 51 is vertically disposed on one side of the mounting bracket 41 and located on the sliding path of the base 21. A guide pin 52 is vertically connected to the output end of the fifth drive source 51.

[0022] This utility model discloses a device for pressing and riveting products. By setting an automatic switching device, the pressing head 44 and the riveting head 45 can be automatically switched. The pressing and riveting processes of the product can be completed on the same machine in sequence without the need for secondary clamping and tooling changes, which greatly improves the production efficiency and reduces the labor intensity of the workers. The automated production process also greatly reduces the risk of missing or incorrectly installing the pressing head 322 due to human factors, avoids product quality problems caused by human error, and effectively improves the product qualification rate.

[0023] Specifically, the material carrier assembly 2 can slide under the drive of the first drive source 25, thereby moving between the pressing sleeve position and the product guiding position. The positioning pin 23 of the material carrier assembly 2 corresponds to the two hole structures on the product, which is used to initially position the product, ensuring that the product can be accurately placed on the material carrier assembly 2 and preventing the product from shifting position during subsequent processing. The material carrier block 24 is used to support the product and provide stable support for the product.

[0024] The clamping assembly 3 is used to clamp and fix the product on the loading assembly 2 to prevent the product from shifting during the pressing and riveting process; through the driving action of the second driving source 31, the clamping arm 32 can be driven to achieve telescopic movement, thereby clamping or releasing the product placed on the loading assembly 2.

[0025] Driven by the fourth drive source 43, the pressing head 44 and the riveting head 45 can move laterally to the working position corresponding to the product below, realizing the automatic switching of the pressing head 44 and the riveting head 45. When the third drive source 42 is working, it can drive the connecting plate 46 to move up and down, thereby driving the pressing head 44 and the riveting head 45 to move up and down to complete the pressing or riveting action.

[0026] The fifth drive source 51 can drive the guide pin 52 to perform lifting and lowering actions, thereby further guiding the product placed on the material carrier 2 to ensure that the product is in the correct position and to guarantee processing accuracy.

[0027] Reference Figure 3 As shown, the cabinet 1 is further provided with at least two parallel first slide rails, the base 21 is slidably connected to the two first slide rails by a first slider, the first drive source 25 is provided parallel to the first slide rails on the cabinet 1 and located between the two first slide rails, and the output end of the first drive source 25 is connected to the base 21.

[0028] Furthermore, the material carrier block 24 has an arc-shaped groove. The shape of this groove matches the shape of the product to be processed, which can further improve the stability of the product on the material carrier block 24 and prevent the product from shaking during processing.

[0029] Reference Figure 4 As shown, the clamping arm 32 further includes a clamping arm body 321 and a pressure head 322. One end of the clamping arm body 321 is vertically connected to the output end of the second drive source 31, and the other end is connected to the pressure head 322. A clearance groove is provided on the working surface of the pressure head 322. Specifically, during the clamping process, the pressure head 322 directly contacts the product. The clearance groove on the working surface of the pressure head 322 can prevent the pressure head 322 from interfering with other structures on the product when clamping the product, ensuring smooth clamping operation, and also better conforming to the product surface, improving clamping stability.

[0030] Reference Figure 5 and Figure 6 As shown, further, the connecting plate 46 is symmetrically provided with two second slide rails parallel to the first slide rail. The sliding plate 47 is slidably connected to the two second slide rails via a second slider. The connecting plate 46 is provided with two limiting screws 48 located between the two second slide rails, with the two limiting screws 48 located on opposite sides of the sliding plate 47. Specifically, the limiting screws 48 are used to limit the sliding range of the sliding plate 47, preventing it from sliding excessively and detaching from the second slide rails during the sliding process. They also ensure that the sliding plate 47 can accurately stop at the designated position, guaranteeing that the pressing head 44 and the riveting head 45 can accurately align with the processing position of the product. Specifically, when the sliding plate 47 abuts against one of the limiting screws 48, the pressing head 44 is in the working position; when the sliding plate 47 abuts against the other limiting screw 48, the riveting head 45 is in the working position.

[0031] Furthermore, the mounting bracket 41 includes multiple vertically connected support columns to the cabinet. A support plate is horizontally connected to the top of each support column. Two linear bearings are vertically mounted on the support plate, and a sliding rod is slidably connected to each of the two linear bearings. A connecting plate 46 is vertically connected between the ends of the two sliding rods near the bottom of the support plate. A third drive source 42 is vertically connected to the support plate, and its output end is vertically connected to the connecting plate 46. It is conceivable that the cooperation between the linear bearings and the sliding rods ensures the perpendicularity of the pressing action of the riveting head 45 and the pressing sleeve head 44, which is beneficial for improving processing accuracy.

[0032] Furthermore, the system includes a controller, which is connected to the first drive source 25, the second drive source 31, the third drive source 42, the fourth drive source 43, and the fifth drive source 51. Specifically, the controller controls the working status of each drive source, enabling coordinated operation between the various components of the equipment. Operators can set relevant processing parameters through the controller, such as the movement speed, stroke, and clamping force of each drive source. The controller automatically controls each drive source to operate according to a preset program based on the set parameters, completing a series of processing steps such as product loading, positioning, clamping, guiding, pressing, and riveting, thus achieving automated processing operation of the equipment.

[0033] Furthermore, a detection light curtain is included, which is installed on cabinet 1 and connected to a controller. Specifically, during equipment operation, the detection light curtain can detect the operator's hands and other body parts. If an object is detected entering the danger zone, a signal can be promptly transmitted to the controller, which will then stop the equipment from operating, preventing accidents from occurring.

[0034] Furthermore, the free end of the guide pin 52 is tapered. Specifically, the guide pin 52 is a cylindrical structure with one end machined into a cone, which serves as a guide to ensure smooth docking between the guide pin 52 and the product.

[0035] Workflow: The operator places the product to be processed onto the loading block 24 of the loading assembly 2, and initially positions the product using the positioning pin 23. Then, the second drive source 31 actuates, driving the clamping arm 32 to clamp the product. Next, the first drive source 25 drives the loading assembly 2 to move below the clamping guide assembly 5, and the fifth drive source 51 drives the guide pin 52 to guide the product (during guidance, the clamping assembly 3 releases the product). After guidance is complete, the first drive source 25 drives the loading assembly 2 to reset. Then, the fourth drive source 43 drives the sliding plate 47 to slide, causing the pressing head 44 to move to the working position corresponding to the product, and performs a pressing action under the drive of the third drive source 42. After pressing, the third drive source 42 resets. The fourth drive source 43 then drives the sliding plate 47 to slide, causing the riveting head 45 to move to the working position and perform a riveting action under the drive of the third drive source 42. After riveting, the third drive source 42 resets. Finally, the second drive source 31 drives the clamping arm 32 to release the product, completing one full pressing and riveting process.

[0036] Example 2: This utility model also discloses a production line, including the equipment for pressing and riveting products as in Example 1.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
