Description

Technical Field

[0001] This utility model relates to the field of electric cylinder equipment technology, specifically a dual-guided multi-stage electric cylinder. Background Technology

[0002] An electric cylinder is a device that converts the rotary motion of an electric motor into the linear motion of a push rod through mechanical structures such as a lead screw. It is widely used in industrial automation, robotics, precision positioning and other fields.

[0003] For example, the utility model patent disclosed in publication number CN219643728U discloses a multi-stage electric cylinder, including a cylinder body, a fixed plate installed on one side of the cylinder body, multiple connecting components installed between the cylinder body and the fixed plate, support base plates fixedly connected to both sides of the bottom of the cylinder body, a fixed screw fixedly connected to one side of the fixed plate, a drive mechanism fixedly connected to the bottom center of the cylinder body, a transmission sleeve rotatably connected to the inner wall of the cylinder body, a multi-stage output mechanism provided between the inner wall of the transmission sleeve and the fixed screw, and rolling steel balls installed on both sides of the transmission sleeve, respectively, with the inner wall of the cylinder body and one side of the fixed plate. This utility model achieves sealing of the first-stage and second-stage sleeves through the design of a first sealing ring and a second sealing ring. After use, the shrinkage effectively cleans dust, and the tight fit between the transmission sleeve and the inner wall of the cylinder body prevents dust from entering the fixed housing, thus affecting the service life of the transmission worm gear.

[0004] Although the aforementioned electric cylinder can perform multi-stage output, it can only perform unidirectional output, which makes its adaptability insufficient and reduces its practical performance under different working conditions. Therefore, there is an urgent need for a dual-guided multi-stage electric cylinder to solve the above-mentioned problems. Utility Model Content

[0007] The alignment card holder has two sets, and the two sets of alignment card holders are respectively arranged at the front and rear of the limiting card holder. A guide groove is opened at the center of the inner end face of the alignment card holder, and four sets of straight grooves are equally spaced on the inner end face of the guide groove.

[0008] A transmission device, which engages and rotates within the limiting seat via the drive gear, is used for bidirectional power output.

[0009] A guide device, which is threadedly connected to the inside of the alignment seat via the transmission device, is used for secondary telescopic movement.

[0010] Preferably, the transmission device includes a driven gear, the inner end face of which is fixedly engaged with a positioning shaft, and a first-stage lead screw is provided at both ends of the positioning shaft.

A threaded guide seat is threadedly connected to the top of the threaded guide sleeve through the secondary lead screw, and four sets of linear sliding shafts are equidistantly arranged at the lower end face of the threaded guide seat.

[0012] Preferably, the threaded guide seat is adapted to the alignment bushing via the linear sliding shaft and is slidably engaged with the upper part of the threaded guide sleeve, which can effectively improve the stability of the subsequent secondary lead screw driving the threaded guide seat to perform secondary telescopic axial displacement.

[0013] Preferably, the threaded guide sleeve is threadedly connected to the inner end face of the alignment slot via the first-stage lead screw, and the driving gear meshes with the driven gear, which can effectively improve the stability of the equipment's transmission.

[0014] Preferably, the threaded guide sleeve is adapted to the linear slide groove by the limiting slider and then slidably engaged with the inner end face of the alignment seat. The adaptation of the limiting slider and the linear slide groove can effectively improve the stability of the threaded guide sleeve sliding axially inside the alignment seat, thereby improving the stability of the thrust provided to the equipment.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. By setting up a transmission device and a guiding device, when the equipment outputs power, the servo motor can synchronously drive the two sets of guiding devices to perform telescopic displacement through the meshing of the driving gear and the driven gear, thereby providing bidirectional power to the equipment and effectively improving the adaptability of the equipment to power output under different working conditions. At the same time, the geared motor can drive the threaded guide seat to perform two-stage telescopic guidance through the two-stage lead screw, further improving the practical performance of the equipment in performing multi-stage power output, and also improving the adaptability of the equipment.

An alignment groove 1 for docking is provided at the center of the inner end face of the limiting seat 8.

[0025] Alignment seat 5, there are two sets of alignment seat 5, and the two sets of alignment seat 5 are respectively set at the front and rear of the limiting seat 8. A guide groove 4 is opened at the center of the inner end face of the alignment seat 5, and four sets of straight grooves 2 are equally spaced on the inner end face of the guide groove 4.

[0026] Transmission device 3 is engaged and rotated inside the limiting seat 8 via drive gear 7. Transmission device 3 is used for bidirectional power output.

[0027] The guide device 6 is threadedly connected to the inside of the alignment seat 5 via the transmission device 3. The guide device 6 is used for secondary telescopic movement.

[0028] like Figure 3 The transmission device 3 includes a driven gear 31, with a positioning shaft 33 fixedly engaged on the inner end face of the driven gear 31, and a first-stage lead screw 32 is provided on both sides of the positioning shaft 33.

[0029] like Figure 4 and Figure 5 The guiding device 6 includes a threaded guide sleeve 64. Four sets of limiting sliders 65 are equidistantly arranged at the bottom of the side end face of the threaded guide sleeve 64. A reduction motor 66 is fixedly clamped at the top center of the threaded guide sleeve 64. A secondary lead screw 67 is arranged at the output end of the reduction motor 66. Four sets of alignment bushings 63 are equidistantly arranged at the top of the side end face of the threaded guide sleeve 64. A threaded guide seat 61 is threadedly connected to the top of the threaded guide sleeve 64 through the secondary lead screw 67. Four sets of linear sliding shafts 62 are equidistantly arranged at the lower end face of the threaded guide seat 61.

[0030] like Figure 4 The threaded guide seat 61 is adapted to the alignment bushing 63 through the linear sliding shaft 62 and then slidably engaged on the upper part of the threaded guide sleeve 64, which can effectively improve the stability of the subsequent secondary lead screw 67 driving the threaded guide seat 61 to perform secondary telescopic axial displacement. The end of the threaded guide seat 61 is provided with a flange, which facilitates quick and accurate docking and installation with the subsequent processing equipment.
