Description

Technical Field

[0001] The utility model relates to the technical field of floor spring accessories processing, in particular to a floor spring end cover tapping device. Background Art

[0002] Floor spring is a hydraulic door closer, and its basic configuration is top axis and bottom axis. Top axis is the accessory that connects the door frame and the door leaf at the top, and consists of a bolt-type axis fixed to the door leaf and adjustable by bolts, and a shaft sleeve fixed to the door leaf. Top axis and bottom axis can be applied to almost all wooden, steel, aluminum alloy doors and frameless glass doors using glass door clamps.

[0003] In order to cooperate with the installation and disassembly of the sky axis, ground axis and other accessories of the floor spring, the floor spring is equipped with a floor spring end cover in addition to the load-bearing seat. The sky axis, ground axis and other accessories of the floor spring are realized through the threaded connection between the floor spring end cover and the load-bearing seat.

[0004] Generally, multiple holes to be tapped on the end caps of floor springs are tapped synchronously through a clamping mechanism in conjunction with a multi-axis tapping machine. However, before each tapping operation, the end caps of floor springs to be tapped must be clamped in the clamping mechanism. After the tapping operation is completed, the end caps of floor springs to be tapped must be removed and the next set of end caps to be tapped must be clamped. The waiting time between two adjacent tapping operations is long, which reduces the tapping efficiency of the end caps of floor springs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a floor spring end cover tapping device, which can improve the tapping efficiency of the floor spring end cover.

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to more clearly understand the technical ideas claimed for protection by the present invention. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0030] like Figures 1 to 7 As shown, a floor spring end cover tapping device in an embodiment of the utility model includes a frame 100, a tapping table 200 slidably connected to the frame 100, a translation drive component 300 installed on the frame 100 for driving the tapping table 200 to switch positions back and forth, and a tapping device 400 installed on the frame 100; in fact, the translation drive component 300 can be a cylinder, a hydraulic rod, a single-axis translation table, etc., to drive the tapping table 200 to move left and right to switch positions.

[0031] The tapping table 200 is provided with two tapping stations at intervals on the left and right, and the tapping station is provided with a clamping device 500 for clamping and fixing the floor spring end cover, and the tapping device 400 is used for tapping the floor spring end cover on the tapping station; in fact, the clamping device 500 on the tapping station is used to clamp and fix the floor spring end cover, and a through hole is provided in the middle of the floor spring end cover. The clamping device 500 can be a positioning pin that cooperates with the floor spring through hole or an opening and closing clamping mechanism that extends into the floor spring through hole, so as to fix the relative position of the floor spring end cover and the tapping table 200. In addition, in order to facilitate the positioning of the floor spring end cover, the tapping station can also be provided with a positioning block to facilitate the clamping and fixing of the floor spring end cover; the tapping device 400 can be a multi-axis tapping machine, multiple single-axis tapping machines or a tapping robot with multiple tapping output ends, which can simultaneously tap multiple holes to be tapped on the floor spring end cover.

[0032] The specific working process of the floor spring end cap tapping device in the embodiment of the utility model is as follows: first, the floor spring end cap to be tapped is clamped on the clamping device 500 on the tapping station on the right side of the tapping table 200; the translation driving component 300 drives the tapping table 200 to move left relative to the frame 100, so that the floor spring end cap to be tapped on the tapping station on the right side enters directly below the tapping output end of the tapping device 400, and the tapping device 400 taps the floor spring end cap on the tapping station on the right side, and at the same time, the clamping device 500 on the tapping station on the left side is used to tap the floor spring end cap. The end cap of the floor spring to be tapped is clamped on the device 500; after the tapping device 400 completes tapping, the translation driving component 300 drives the tapping table 200 to move rightward relative to the frame 100, so that the end cap of the floor spring to be tapped on the left tapping station enters directly under the tapping output end of the tapping device 400, and the tapping device 400 taps the end cap of the floor spring on the left tapping station. At the same time, the tapped end cap of the floor spring is removed from the clamping device 500 on the right tapping station and the end cap of the floor spring to be tapped is clamped; and the cycle is repeated.

[0033] The floor spring end cap tapping equipment in the embodiment of the utility model cooperates with each other through the frame 100, the tapping table 200, the translation drive component 300, the tapping device 400 and the clamping device 500. When the tapping device 400 taps the floor spring end cap on the tapping station on one side, the operator can use the clamping device on the tapping station on the other side to remove the tapped floor spring end cap and clamp the floor spring end cap to be tapped, thereby reducing the standby time between two adjacent tapping operations and improving the tapping efficiency of the floor spring end cap.

[0034] Furthermore, each of the tapping stations is preferably provided with multiple groups of clamping devices 500 at intervals on the left and right. In fact, each group of clamping devices 500 clamps one floor spring end cap, and each tapping station can cooperate with the tapping device 400 to process multiple floor spring end caps at one time, further improving the processing efficiency of the floor spring end caps. Each tapping station drawn in the drawings of the utility model has two groups of clamping devices 500. Specifically, the number of clamping devices 500 at each tapping station can be adjusted according to actual needs.

[0035] It should be noted that the clamping device 500 preferably includes a limiter 510 installed on the tapping station 200 and used to extend into the middle through hole of the floor spring end cover; the limiter 510 can be one or more, and the floor spring end cover is clamped by being limited by the inner wall of the middle through hole of the floor spring end cover.

[0036] Furthermore, the stopper 510 preferably includes a plurality of stoppers 511 evenly distributed around the circumference and radially slidably connected to the tapping station 200, a synchronization block 512 for driving the plurality of stoppers 511 to open synchronously, and a clamping drive component 513 mounted on the frame 100 for driving the synchronization block 512 to move. Figure 2 and Figure 5 As shown, the clamping drive component 513 can be a cylinder, a hydraulic rod or an electric telescopic rod, which can drive the synchronous block 512 to move back and forth. When the clamping drive component 513 drives the synchronous block 512 to move, it drives multiple limit blocks 511 to move radially outward, so that the outer side of the limit block 511 is against the inner wall of the middle through hole of the floor spring end cover, thereby clamping the floor spring end cover; when the floor spring end cover needs to be removed, the clamping drive component 513 drives the synchronous block 512 to reset, and multiple limit blocks 511 can move radially inward and release the inner wall of the middle through hole of the floor spring end cover, so that the floor spring end cover is easier to remove from the clamping device, thereby facilitating the clamping of the floor spring end cover.

[0037] Furthermore, the synchronization block 512 is preferably a truncated cone whose outer diameter gradually increases from top to bottom, and the lower inner portion of the limit block 511 is a conical arc surface parallel to the outer side surface of the synchronization block 512. Figure 2 As shown, when the synchronization block 512 moves upward, the outer side of the frustum cooperates with the inner lower part of the limit block 511 to make the multiple limit blocks 511 move radially outward. When the synchronization block 512 moves downward, the limit blocks 511 can move radially inward to achieve the clamping and loosening of the clamping device 500 on the ground spring end cover.

[0038] Furthermore, the outer side of the limit block 511 is preferably an arc surface protruding outward and perpendicular to the horizontal plane, so as to avoid contact between the sharp angle surface and the inner wall of the middle through hole of the floor spring end cover, thereby reducing damage to the middle through hole of the floor spring end cover.

[0039] It should be noted that the tapping device 400 preferably includes a tapping frame 410 slidably connected to the frame 100, a plurality of tapping taps 420 installed on the tapping frame 410, a tapping motor 430 installed on the tapping frame 410 and used to drive the plurality of tapping taps 420 to rotate synchronously, and a lifting drive component 440 for driving the tapping frame 410 to move up and down; the lifting drive component 440 can be a cylinder, a hydraulic rod, a single-axis translation table, a robotic arm, etc., which can drive the tapping frame 410 to move up and down to tap the end cover of the floor spring. The number of the tapping taps 420 should be greater than or equal to the number of holes to be tapped at each tapping station to ensure that one tapping operation can complete the tapping of the end cover of the floor spring at the tapping station.

[0040] Furthermore, the tapping device 400 preferably also includes a clamping plate 450 for abutting against the upper side of the floor spring end cover, a plurality of springs 460 whose upper and lower ends respectively abut against the lower side of the tapping frame 410 and the upper side of the clamping plate 450, and a plurality of guide rods 470 fixed to the lower side of the tapping frame 410. The guide rods 470 pass through the springs 460 and are slidably connected to the clamping plate 450 up and down. The clamping plate 450 is provided with a plurality of first clearance holes 451 for a plurality of tapping taps 420 to pass through and a second clearance hole 452 for a clamping device 500 to pass through, so as to avoid interference between the tapping taps 420 and the clamping device 500 and the clamping plate during tapping. When the lifting drive component drives the tapping frame 410 to move downward until the clamping plate 450 abuts against the upper side of the floor spring end cover, the clamping plate 450 and the spring 460 cooperate with the tapping table 200 to further clamp the floor spring end cover, further improving the clamping degree of the floor spring end cover during tapping.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
