Description

Technical Field

[0001] This utility model relates to the field of connector installation technology, specifically a press-fitting device for a cylinder connector. Background Technology

[0002] As is well known, cylinders and floating joints are a very common combination in mechanical design and automation. Floating joints can compensate for cylinder concentricity errors, perpendicularity errors, and angular deviations, eliminating or reducing the damaging stress on the cylinder caused by errors.

[0003] For example, the utility model patent with application announcement number CN221935896U, application announcement date November 1, 2024, entitled "An Automatic Installation Device for a Floating Joint of a Slide Table Cylinder," includes: a base plate, a placement platform, and a telescopic rod. The top of the placement platform has a groove, and a first motor is fixedly connected to the side of the groove. This automatic installation device for a floating joint of a slide table cylinder, through the combined operation of the damping rod, arc plate, and second spring on the side of the clamping plate, provides a buffering effect when clamping the part. During installation, the placement platform is pressed downwards, which causes the third fixing block, support bar, and second fixing block to move together, causing the second fixing block to slide along the outer edge of the first fixing rod. Then, the rebound of the first spring provides a certain degree of buffering and shock absorption when the placement platform is pressed down. This structure can effectively fix and clamp the part, while also buffering and absorbing shock on the placement plate, preventing damage to the part due to excessive downward pressure during installation.

[0004] The drawback of the existing technology is that when the floating joint is connected to the piston of the cylinder, the piston is prone to move relative to the cylinder, which leads to misalignment or difficulty in tightening the floating joint. This requires the piston to be fixed with a clamp first, and then the operator has to manually install the joint onto the piston of the cylinder. The work steps are complicated and the physical burden on the operator is relatively large. Summary of the Invention

[0005] The purpose of this invention is to provide a press-fitting device for cylinder connectors to address the aforementioned shortcomings in the prior art.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a cylinder connector press-fitting device, including a frame 1, a movable plate 11 and a fixed plate 12 for supporting the piston of the cylinder on the frame 1, a slot 121 for fixing the hexagonal head of the piston top on the fixed plate 12, and a movable ring 111 concentric with the slot 121 for limiting the floating connector on the movable plate 11. The movable plate 11 moves down to make the floating connector fit with the top of the piston, and the movable ring 111 rotates to make the floating connector threadedly connected to the piston.

[0022] Specifically, the movable plate 11 is provided with tenons extending into the frame 1, the frame 1 is provided with mortises that fit the tenons, an electric telescopic rod is provided between the tenons and the frame 1, and the snap-fit ​​part 2 at the bottom of the floating joint is disc-shaped with parallel notches on both sides.

[0023] Furthermore, during operation, the hexagonal head at the end of the cylinder piston is manually inserted into the slot 121 on the fixed plate 12, and then the snap-fit ​​part 2 of the floating joint is snapped into the movable ring 111 on the movable plate 11. At this time, the snap-fit ​​part 2 of the floating joint is concentric with the top of the piston. The electric telescopic rod extends and pushes the tenon and the movable plate 11 downward. The movable plate 11 moves downward with the movable ring 111 and the floating joint. The snap-fit ​​part 2 of the floating joint is engaged with the top of the piston, and the movable ring 111 drives the floating joint to rotate, so that the floating joint is threadedly connected to the piston. The installation steps are simple and only require the electric telescopic rod to drive, which reduces the physical burden on the workers.

[0024] In another embodiment of the present invention, the movable ring 111 is symmetrically provided with a locking block 112 for securing the floating joint locking part 2, and the movable ring 111 is symmetrically and movably provided with an arc plate 113 for clamping the floating joint locking part 2, and a baffle 114 is provided on the arc plate 113 that abuts against the top of the floating joint locking part 2.

[0025] Specifically, a ramp is provided on the side wall of the two adjacent arc plates 113, and a spring is provided between the arc plate 113 and the movable ring 111.

[0026] Furthermore, when fixing the floating joint in the movable ring 111, the parallel notches on both sides of the floating joint locking part 2 are aligned with the space between the two locking blocks 112 inside the movable ring 111, and the locking part 2 moves along the slope at the top of the arc plate 113, pushing the arc plate 113 to slide on the movable ring 111, making room for the locking part 2 to move. The spring between the arc plate 113 and the movable ring 111 accumulates elastic potential energy, and then the floating joint is pushed laterally, so that the locking part 2 moves between the two locking blocks 112 and the arc surface of the locking part 2 is concentric with the arc plate 113. At this time, the arc plate 113 is reset under the push of the spring, the two arc plates 113 come together and abut against the arc surface of the locking part 2, and the baffle 114 at the top of the arc plate 113 abuts against the top of the locking part 2, fixing the locking part 2.

[0027] In another embodiment of the present invention, a transmission wheel 131 coupled to a movable ring 111 is provided on the movable plate 11, a first bevel gear 132 is provided on the transmission wheel 131, a second bevel gear 133 meshing with the first bevel gear 132 is rotatably provided on the movable plate 11, a drive wheel 134 extending into the frame 1 is provided on the second bevel gear 133, and a rack 136 coupled to the drive wheel 134 is provided on the frame 1.

[0028] Specifically, as the movable plate 11 moves downward, the rack 136 on the frame 1 and the drive wheel 134 coupled thereto rotate. The drive wheel 134 drives the second bevel gear 133 to rotate through the first bevel gear 132. The second bevel gear 133 drives the movable ring 111 to rotate through the transmission wheel 131. The movable ring 111 drives the floating joint to rotate and tighten onto the piston.

[0029] Furthermore, in the above embodiments, both the drive wheel 134 and the transmission wheel 131 are gears.

[0030] In another embodiment of the present invention, the movable ring 111 is provided with a notch and a sealing plate 115 for closing the notch and opening and closing outward.

[0031] Specifically, the sealing plate 115 is hinged to the movable ring 111, and a torsion spring is provided between the sealing plate 115 and the movable ring 111.

[0032] Furthermore, when the movable plate 11 moves to the lowest point, the floating joint connects to the piston of the cylinder, and the sealing plate 115 is directly opposite the notch on the movable plate 11. At this time, the cylinder and the floating joint can be pulled outward, and the snap-fit ​​part 2 of the floating joint pushes the arc plate 113 from the inside. The two arc plates 113 slide and separate relative to the movable ring 111, and the snap-fit ​​part 2 pushes the sealing plate 115, so that the notch on the movable ring 111 opens, and the floating joint can be directly removed from the movable ring 111.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
