Description

Technical Field

[0001] This utility model relates to the technical field of door closer end cap loading and unloading, and in particular to a door closer vertical locking end cap machine. Background Technology

[0002] The locking and unlocking of the door closer end cap is a critical process in production. Traditional methods rely on manual operation using an electric wrench, which has significant drawbacks:

[0003] First, uneven tightening force during manual tightening can easily damage the end cap threads or cause poor sealing, and repeated adjustments to the alignment angle are necessary, resulting in low efficiency. Second, although existing semi-automatic equipment can clamp the end caps, it lacks an effective anti-displacement positioning mechanism, making the end caps prone to shifting during the pressing process, causing thread misalignment and rendering the equipment unusable. In addition, special tools must be replaced when disassembling defective products, resulting in low equipment reuse rate.

[0004] Although some devices attempt to integrate clamping and cap screwing functions, their mechanical structure cannot coordinate the connection between manual alignment and automatic locking—after manual intervention, repositioning is required, or forced pressing causes indentations on the end cap surface.

[0005] Therefore, the inventors urgently need a vertical locking end cap machine for door closers to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned defects in the prior art, this utility model provides a door closer vertical locking end cap machine, which aims to solve the problems in the prior art where manual operation and automatic locking cannot be effectively connected during the assembly of door closer end caps, resulting in poor positioning accuracy, easy deviation, and incompatibility of disassembly and assembly tools.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a vertical door closer locking end cap machine, comprising an outer support frame, wherein a product fixing mechanism, an end cap clamping and positioning mechanism, and an end cap tightening mechanism are sequentially arranged from bottom to top within the outer support frame. The end cap clamping and positioning mechanism includes an end cap positioning and lifting assembly and a clamping and positioning assembly disposed at the output end of the end cap positioning and lifting assembly. The clamping and positioning assembly is used to clamp and position the end cap. The end cap tightening mechanism includes a lifting cylinder, a rotary motor disposed at the output end of the lifting cylinder, and a manual alignment component. The manual alignment component includes a retraction limiting structure and a rotating alignment head disposed at the lower end of the retraction limiting structure. The retraction limiting structure includes a mounting head slidably fitted onto an extension rod at the output end of the rotary motor and elastic fasteners symmetrically hinged to both sides of the upper end of the mounting head. The lower inner side of the elastic fastener is connected to the mounting head via a spring, and the upper end of the elastic fastener is snapped onto a limiting protrusion on the outer side of the output end of the rotary motor.

[0008] Based on the above, a vertical locking end cap machine for door closers solves the problems in the existing technology where manual operation and automatic locking cannot be effectively connected during the assembly of door closer end caps, resulting in poor positioning accuracy, easy deviation, and incompatibility of disassembly and assembly tools; mainly reflected in:

[0009] 1. This utility model allows the operator to manually pull down and rotate the alignment head by pulling the alignment component, so that its protrusion is accurately inserted into the end cap groove to complete the initial alignment. This realizes that manual intervention is only used for critical and flexible initial positioning, while all subsequent precision actions are completed automatically by the machine. This effectively connects manual operation with automatic locking and solves the problem of poor positioning accuracy after manual operation.

[0010] 2. This utility model uses a forward-pushing positioning component. After manual alignment, the positioning block is driven by its outward-pushing positioning cylinder to press the side of the end cover through a spring buffer. This dynamically prevents the end cover from shifting during the pressing process, solves the problem of assembly misalignment caused by easy displacement, and ensures the accurate starting point of automatic locking.

[0011] 3. This utility model, through the design of the elastic fastener and the limiting protrusion of the retractable limiting structure, causes the installation head to rise and reset along the extension rod when the lifting electric cylinder continues to press down, until the elastic fastener automatically latches and locks on the limiting protrusion, thus achieving a seamless transition from the state after manual alignment to the mechanical locking state, and solving the connection problem when switching between manual operation and locking steps.

[0012] 4. This utility model uses a rotary motor-driven end cap tightening mechanism. By simply controlling the forward and reverse rotation of the rotary motor, the tightening and loosening of the end cap can be completed on the same equipment without replacing any parts. This completely solves the problem of incompatibility between disassembly and assembly tools, and improves equipment utilization and ease of operation.

[0013] 5. This utility model achieves coordinated lifting control of the end cap clamping and positioning mechanism and the end cap screwing mechanism. After the forward positioning component is reset in time, the end cap screwing mechanism independently completes the pressing, locking and rotation actions, thus realizing the continuous execution of the entire process of "placement-positioning-pressing-locking / releasing", improving positioning accuracy and assembly efficiency.

[0014] Furthermore, the end cap clamping and positioning mechanism also includes a mounting frame. The clamping and positioning assembly includes a clamping component mounted on the upper end of the mounting frame and a forward-pushing positioning component mounted on the lower end of the mounting frame. The clamping component includes a double-headed clamping cylinder and end cap single clamps symmetrically arranged at the two output ends of the double-headed clamping cylinder. The forward-pushing positioning component includes an outward-pushing positioning cylinder, a top-pushing guide block arranged at the output end of the outward-pushing positioning cylinder, and a positioning block. A sliding guide rod is provided on the positioning block. The sliding guide rod is limited to sliding within the guide hole of the top-pushing guide block. A spring is sleeved on the sliding guide rod. The spring is located between the top-pushing guide block and the positioning block. The positioning block is located below the clamping component.

[0015] Based on the above, the beneficial effects of the mounting bracket are that it fixes the clamping component and the forward positioning component on the same frame in layers, realizing spatial coordination of clamping and positioning actions. This ensures that while the end cap is being clamped, it can simultaneously receive the pressure of the positioning block in the horizontal direction, solving the problem of matching error caused by the separation of clamping and positioning mechanisms in traditional equipment. The beneficial effect of the spring in the forward positioning component as a buffer structure is that when the positioning block presses against the end cap through the sliding guide rod, the spring absorbs mechanical impact and maintains constant pressure, realizing flexible contact for lateral positioning of the end cap. This not only prevents damage to the surface of the end cap but also ensures the reliability of offset correction.

[0016] Furthermore, the product fixing mechanism includes a product frame and a positioning motor installed on the outside of the product frame. The output end of the positioning motor is provided with a rotating positioning rod, and the rotation range of the rotating positioning rod is located at the opening of the product frame and its outside.

[0017] Based on the above, the beneficial effect of the rotating positioning rod driven by the positioning motor is that it automatically rotates to the outside of the opening after the door closer is placed in the product rack, thus achieving flexible positioning of the product and preventing it from shifting or shaking during the tightening of the end cap, ensuring the stability and accuracy of the assembly process.

[0018] Furthermore, the lower end of the rotating alignment head is provided with several protrusions, each of which corresponds one-to-one with several grooves on the upper end of the end cap to be assembled.

[0019] Based on the above, the one-to-one correspondence between the protrusions and the grooves has the beneficial effect of generating a clear positioning feedback when manually rotating the alignment head, enabling operators to quickly judge whether the alignment is accurate through touch, which significantly improves the intuitiveness of human-computer interaction and the reliability of operation.

[0020] Furthermore, safety light curtains are provided on both sides of the front end of the outer support frame.

[0021] Based on the above, the beneficial effects of safety light curtains are that they create a three-dimensional protection area without blind spots, enabling real-time monitoring of the operator's hands and other body parts, and completely solving the problems of slow response and blind spots in traditional mechanical protective devices.

Detailed Implementation

[0030] like Figures 1-6As shown, a vertical door closer locking end cap machine includes an outer support frame 2. Inside the outer support frame 2, from bottom to top, are a product fixing mechanism 3, an end cap clamping and positioning mechanism 4, and an end cap tightening mechanism 5. The end cap clamping and positioning mechanism 4 includes an end cap positioning and lifting assembly 41 and a clamping and positioning assembly 42 located at the output end of the end cap positioning and lifting assembly 41. The clamping and positioning assembly 42 is used to clamp and position the end cap. The end cap tightening mechanism 5 includes a lifting electric cylinder 51, a rotary motor 52 located at the output end of the lifting electric cylinder 51, and a manual alignment component 53. The manual alignment component 53 includes a retraction limiting structure 531 and a rotating alignment head 532 disposed at the lower end of the retraction limiting structure 531. The retraction limiting structure 531 includes a mounting head 5311 slidably fitted on the extension rod 521 at the output end of the rotary motor 52 and elastic fasteners 5312 symmetrically hinged to both sides of the upper end of the mounting head 5311. The inner side of the lower end of the elastic fastener 5312 is connected to the mounting head 5311 by a spring, and the upper end of the elastic fastener 5312 is snapped into the limiting protrusion 522 on the outer side of the output end of the rotary motor 52.

[0031] The end cap clamping and positioning mechanism 4 further includes a mounting frame 43. The clamping and positioning assembly 42 includes a clamping component 421 mounted on the upper end of the mounting frame 43 and a forward positioning component 422 mounted on the lower end of the mounting frame 43. The clamping component 421 includes a double-headed clamping cylinder 4211 and end cap single clamps 4212 symmetrically arranged at the two output ends of the double-headed clamping cylinder 4211. The forward positioning component 422 includes an outward positioning cylinder 4221 and an end cap single clamp 4212 symmetrically arranged at the two output ends of the double-headed clamping cylinder 4211. The output end of the outward positioning cylinder 4221 includes a push guide block 4222 and a positioning block 4223. The positioning block 4223 is provided with a sliding guide rod 4224. The sliding guide rod 4224 is limited to sliding within the guide hole of the push guide block 4222. A spring 4225 is sleeved on the sliding guide rod 4224. The spring 4225 is located between the push guide block 4222 and the positioning block 4223. The positioning block 4223 is located below the clamping component 421.

[0032] The product fixing mechanism 3 includes a product rack 31 and a positioning motor 32 installed on the outside of the product rack 31. The output end of the positioning motor 32 is provided with a rotating positioning rod 321. The rotation range of the rotating positioning rod 321 is located at the opening of the product rack 31 and its outside.

[0033] The lower end of the rotating alignment head 532 is provided with a number of protrusions 5321, each of which corresponds one-to-one with a number of grooves on the upper end of the end cap to be assembled.

[0034] Safety light curtains 6 are provided on both sides of the front end of the outer support frame 2.

[0035] In summary, the specific embodiments of this utility model are as follows:

[0036] During the end cap tightening operation, the operator first manually places the end cap on the output end of the clamping component 421, activates the double-headed clamping cylinder 4211 to drive the two end cap single clamps 4212 to clamp the end cap, and then manually pulls down the rotating alignment head 532 of the alignment component 53, so that the mounting head 5311 slides down along the extension rod 521 at the output end of the rotary motor 52. At the same time, the alignment head 532 rotates so that the several protrusions 5321 set at its lower end are aligned and inserted into the groove at the upper end of the end cap. Meanwhile, the outward positioning cylinder 4221 of the forward positioning component 422 drives the top push guide block 4222 to push the positioning block 4223 to press against the side of the end cap. The sliding guide rod 4224 slides in the guide hole of the top push guide block 4222, and the spring 4225 provides buffering force to ensure that the positioning block 4223 is positioned stably.

[0037] The end cap positioning and lifting assembly 41 and the lifting cylinder 51 start synchronously, driving the clamping component 421, the forward positioning component 422 and the rotating alignment head 532 to move down as a whole. When the positioning block 4223 approaches the product on the product rack 31, the outward positioning cylinder 4221 resets and retracts the positioning block 4223. After the end cap contacts the product, the end cap positioning and lifting assembly 41 stops running, and the lifting cylinder 51 continues to press down, causing the mounting head 5311 to rise and reset along the extension rod 521 until the elastic fastener 5312 is snapped onto the limit protrusion 522 on the outside of the output end of the rotary motor 52. At this time, the clamping component 421 releases the end cap, the rotary motor 52 starts, and the tightening operation of the end cap is completed by rotating the alignment head 532.

[0038] During the end cap loosening operation, the operator places the defective product on the product rack 31. The positioning motor 32 drives the rotating positioning rod 321 to rotate to the outside of the opening of the product rack 31 for limiting. After manually pulling down the rotating alignment head 532 to complete the alignment, the lifting electric cylinder 51 presses down to make the elastic fastener 5312 engage with the limiting protrusion 522. The rotating motor 52 reverses to loosen the end cap. The end cap positioning lifting assembly 41 drives the clamping component 421 to move down and clamp the loosened end cap. Together with the lifting electric cylinder 51, it rises and resets to complete the disassembly operation. Throughout the entire operation, the safety light curtains 6 set on both sides of the front end of the outer support frame 2 monitor the work area in real time to ensure operational safety.

[0039] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model. Various modifications or substitutions made by those skilled in the art to this utility model without departing from the essence and protection scope of this utility model should also be within the protection scope of this utility model.
