[0040] As Figure 1As shown, the present application provides an upper-mounted spring press-fitting device for lever lock assembly, which comprises a feeding unit 1 and a mounting unit 3 arranged beside the feeding unit 1. The feeding unit 1 is used to place the spring in a horizontal state on the first position to be transported. A horizontal moving unit 2 is arranged between the feeding unit 1 and the mounting unit 3. The horizontal moving unit 2 is used to move the spring on the first position to the second position where the spring is to be clamped. The mounting unit 3 is used to clamp and press-fit the spring on the second position to the tool structure 4. A complete upper-mounted spring press-fitting device is provided, which has a clear structure and can efficiently complete a series of operations such as spring feeding, transportation, clamping and press-fitting. By dividing into the feeding unit 1, the horizontal moving unit 2 and the mounting unit 3, the whole process from feeding to final installation of the spring is ensured to be smooth and unobstructed, reducing manual intervention and improving production efficiency. Through the precise cooperation of multiple units, the spring is accurately clamped and installed on the tool structure 4, avoiding quality problems caused by improper manual operation.

[0041] The feeding unit 1 comprises a guide spring directional moving guide rod 11, and a limiting rod 12 is fixedly arranged at the free end of the guide rod 11 to uniformly guide the direction of the spring and stack the spring. The spring can also be transported to the specified position by using a vibrating disc. Through the design of the vibrating disc and the guide rod 11, the directional movement of the spring in the feeding unit 1 is effectively guided, ensuring the consistent orientation of the spring during transportation and avoiding misalignment or disorder of the spring.

[0042] As shown in Figure 1 The horizontal moving unit 2 comprises a first bracket 21, a sliding table air cylinder 22 is fixedly arranged on the first bracket 21, and a conveying block 24 for moving the spring from the first position to the second position is fixedly arranged on the baffle surface of the sliding table air cylinder 22. By selecting the sliding table air cylinder 22, the stability and precision of the horizontal moving unit 2 are improved. The sliding table air cylinder 22 and the conveying block 24 cooperate to ensure the stable transmission of the spring between the feeding unit 1 and the mounting unit 3, avoiding instability and deviation caused by manual operation. The structure is optimized, the complex mechanical parts are reduced, and the failure rate is reduced. The efficient transmission design ensures that the spring can quickly and stably reach the second position from the first position, improving the production speed and assembly efficiency.

[0043] As shown in Figure 3 A groove 241 for accommodating the spring is formed at one end of the conveying block 24 close to the mounting unit 3. A design for stable transportation of the spring is provided. The design of the groove 241 can accommodate the spring, avoiding sliding and misalignment of the spring during horizontal movement. By accurately accommodating the spring, the conveying block 24 can stably transport the spring to the position of the mounting unit 3, thereby ensuring the accuracy of the spring installation.

[0044] AsFigure 2 As shown, the mounting unit 3 includes a second bracket 31, a second cylinder 32 fixedly arranged on the second bracket 31, a connecting block 33 fixedly arranged on the working end of the second cylinder 32, the connecting block 33 being horizontally slidable on the second bracket 31; a clamping assembly 34 for clamping the circlip is arranged on the side of the connecting block 33 close to the horizontal moving unit 2, and a pressing assembly 35 for pressing the circlip is movably arranged on the other side of the connecting plate; a limiting cover 36 for guiding the limiting circlip to be mounted to the tooling structure 4 is arranged below the second bracket 31. A precise circlip clamping and pressing mechanism is provided, and through the cooperative work of the clamping assembly 34 and the pressing assembly 35, it is ensured that the circlip is stably clamped and correctly pressed to the tooling structure 4. The design of the limiting cover 36 ensures the precise positioning of the circlip during the pressing process, preventing installation deviation. The installation error caused by improper movement of the circlip is avoided. Through the combination of the pressing assembly 35 and the clamping assembly 34 controlled by the cylinder, the automation degree of assembly is improved, and manual operation is reduced.

[0045] As shown in Figure 2 The clamping assembly 34 includes a third cylinder 341 arranged in a vertical state, and a finger cylinder 342 for clamping the circlip is fixedly arranged on the working end of the third cylinder 341. A precise and stable circlip clamping mechanism is provided, and through the cooperation of the third cylinder 341 and the finger cylinder 342, it is ensured that the circlip can be stably clamped and will not slip or loosen before pressing.

[0046] The pressing assembly 35 includes a slide rail 351 fixedly arranged vertically downward, a sliding block 352 slidably arranged on the slide rail 351, a pressing block 353 fixedly arranged above the sliding block 352, a fourth cylinder 354 fixedly arranged on the connecting block 33, and the working end of the fourth cylinder 354 is fixedly arranged on the pressing block 353. The pressing block 353 includes a connecting part 3531 and a pressing part 3532, the connecting part 3531 is fixed to the fourth cylinder 354, and the pressing part 3532 is used for abutting and pressing the circlip. The purpose is to design an efficient and precise pressing mechanism through the cooperation of the slide rail 351, the sliding block 352, the pressing block 353 and the cylinder, so as to ensure the stability and precision of the circlip during the pressing process. The design of the slide rail and the sliding block 352 ensures that the pressing force is uniformly distributed, avoiding the bias phenomenon during the pressing process. The cooperation of the moving block and the cylinder makes the pressing part 3532 abut and press the circlip accurately, ensuring that the circlip is accurately installed in place. The efficient pressing assembly 35 can greatly improve the assembly speed and shorten the production cycle.

[0047] As shown in Figure 4As shown, the pressing part 3532 includes a rectangular column, and a through groove 3533 in the shape of a clamping spring is recessed on the end face of the free end. The inner wall of the through groove 3533 is fixedly provided with a protrusion 3534 for abutting and pressing the clamping spring. The purpose is to optimize the pressing process of the clamping spring. By the protrusions 3534 distributed in the radius of the clamping spring, uniform pressure can be applied to the circumference of the clamping spring. This design ensures the stability and firmness of the clamping spring during the pressing process, avoiding local excessive pressure causing deformation or damage of the clamping spring. The shape of the pressing part 3532 is not fixedly limited, and the edges of the clamping spring that can be symmetrically and stably pressed, such as a thimble or a top rod, can be pressed.

[0048] In an application scenario, the installation unit 3 and the horizontal moving unit 2 are arranged on the installation table and surround the rotating table, and the feeding unit 1 is arranged outside the installation table. Through the combined design of the rotating table and the installation table, the production process can be more flexible, and it is convenient to adjust according to the production demand. The layout of the installation table and the rotating table can optimize the production space and improve the space utilization rate. The rotating table can help the rapid transfer of materials and improve the smoothness of the production line.

[0049] The working process principle is described as follows:

[0050] 1. The clamping spring is guided from the stock bin through the vibration disc or directly through the guide rod 11. The vibration disc sends the clamping spring to the specified position through the vibration effect, and the clamping spring is arranged in a direction through the guide rod 11 and the limiting rod 12. The guide rod 11 ensures that the clamping springs are uniformly stacked in the same direction, preventing misalignment of the clamping springs during subsequent transportation.

[0051] 2. After the feeding unit 1 stably sends the clamping spring to the first position (i.e., the position of the limiting rod 12 stack), the horizontal moving unit 2 starts to work. The horizontal moving unit 2 is composed of a conveying block 24 driven by a gas cylinder. The conveying block 24 moves the clamping spring from the first position of the feeding unit 1 to the second position of the installation unit 3 (i.e., the position of the front end groove 241 of the output block). The conveying block 24 is designed with a groove 241 to ensure stable lifting of the clamping spring, avoiding sliding or deviation of the clamping spring.

[0052] 3. After the clamping spring reaches the second position, the installation unit 3 starts to clamp and press the clamping spring. The installation unit 3 accurately clamps the clamping spring through the clamping assembly 34 driven by the second gas cylinder 32, ensuring that the clamping spring does not misalign. After clamping, the clamping spring is transferred to the pressing area, and the pressing assembly 35 accurately presses the clamping spring into the tool structure 4 through the pressing block 353 driven by the gas cylinder. During pressing, the pressing part 3532 uniformly applies pressure to ensure that the clamping spring is firmly installed.

[0053] 4. A limiting cover 36 is provided below the installation unit 3 to guide the accurate installation of the clamping spring to the target position, avoiding displacement during the pressing process.

[0054] AsFigure 5 and Figure 6 As shown, this application proposes a new improved design for the tooling structure 4, specifically including an outer seat 41. The outer seat 41 has a circular mounting hole 42 vertically extending through it. A cylindrical push bushing 43 is fitted into the mounting hole 42 with clearance. A circular cross-section nesting hole 44 is vertically extending through the middle of the push bushing 43. A mandrel 45 is fitted into the nesting hole 44 with clearance. A set of vertically distributed pre-limiting grooves 452 are symmetrically arranged on both sides of the mandrel 45 along its radial direction. A protruding part at the middle of the upper end of the mandrel 45 is fitted into the mandrel hole. The positioning post 46 and the outer surface of the spindle 45 are provided with a clearance groove 451; the outer seat 41 is provided with a limiting member 47 for limiting the vertical sliding of the spindle 45 and the push bush 43 so that the spindle 45 and the push bush 43 form the lowest position and the highest position; the outer seat 41 is provided with an elastic member 48 for elastically contacting the push bush 43 so that the push bush 43 has a tendency to maintain the lowest position and elastically contacting the spindle 45 so that the spindle 45 has a tendency to maintain the highest position.

[0055] In addition, refer to Figure 7 The diagram shows the assembly of the handle into the tooling structure 4. The conventional handle structure consists of a handle 100, a bushing 200, an inner cover 300 (or a face cover), a gasket 600, a torsion spring 400, a corner limiting block 500, and a retaining spring, which are installed into the tooling structure 4 in sequence.

[0056] In summary, through the precise coordination of the feeding unit 1, the traversing unit 2, and the mounting unit 3, this device can efficiently complete the automatic feeding, transportation, clamping, and pressing of snap rings, significantly reducing manual intervention and improving overall assembly efficiency. Each component of the device is precisely controlled by cylinders to ensure stable transmission and accurate clamping of the snap rings, thereby greatly improving the accuracy of snap ring installation and avoiding errors that may occur during manual operation. The automated design significantly reduces reliance on manual operation, lowers labor costs, and improves the stability and consistency of the production process, reducing quality fluctuations caused by human error. Through the collaborative work of the rotary table and the mounting table, this device optimizes the production space layout, improves the space utilization of the production line, and enhances the flexibility and efficiency of the assembly process.
