Description

Technical Field

[0001] The utility model relates to the technical field of electric push rod equipment, in particular to an electric push rod connecting mechanism. Background Art

[0002] The electric linear actuator is powered by an electric motor, which drives a lead screw nut through a first-stage gear reduction, converting the motor's rotational motion into linear motion of the actuator along the guide rail, and using the motor's forward and reverse rotation to achieve the actuator's reciprocating forward and backward motion. This working principle enables the electric linear actuator to be used as an executive machine in various simple or complex process flows, realizing remote control, centralized control or automatic control.

[0003] As disclosed in the utility model patent with publication number CN214146127U, an electric push rod connection structure includes a device body, the device body includes a push rod body and a connecting device, the lower part of the connecting device is inserted into the upper part of the push rod body, and the object can be quickly fixed through the setting of the connecting device, and it is convenient to disassemble. The setting of the nut column can effectively fix the connecting head, and the outer side of the nut column is smooth, which reduces the friction between the connection with the push rod, not only ensuring the fixation of the connecting head, but also greatly reduces the loss of the push rod connection, thereby improving the service life of the push rod body. At the same time, the setting of the groove can also properly fix the object to avoid shaking of the object, while ensuring the usability of the push rod body. Even if the connecting device is damaged due to improper operation during actual use, it can be replaced in time, which greatly avoids damage to the push rod body. The connecting device not only plays a fixing role, but also protects the push rod body.

[0004] Although the above-mentioned electric push rod connection structure has a certain connection stability, it is connected by bolts and nuts. When the above-mentioned bolts used to limit objects are subjected to huge external pulling force, the bolt threads are easily damaged, which in turn affects the subsequent disassembly. At the same time, the above-mentioned connection structure is not easy to disassemble. Therefore, an electric push rod connection mechanism is urgently needed to solve the above-mentioned problems.

[0015] 1. The utility model provides a guiding device and a connecting device, so that the positioning card seat can be limited by the plug-in card plate, the positioning slide groove and the cone pin shaft, and then quickly and accurately elastically connected to the outside of the positioning card seat, which can not only facilitate the subsequent quick and convenient alignment and installation of the positioning card seat, but also improve the efficiency of subsequent maintenance and disassembly. At the same time, the two sets of relative limiting plug-in shafts can be plugged and limited to the fixed card seat under the elastic support of the spring clamp ring, which can not only improve the stability of the support card shaft limit in the positioning card seat, but also improve the convenience of subsequent disassembly of the support card shaft.

DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The present invention provides an embodiment of an electric push rod connection mechanism, comprising a transmission module 6 for support, a servo motor 1 is provided on one side of the upper end surface of the transmission module 6, and a fixed guide seat 5 is provided on the other side of the upper end surface of the transmission module 6.

[0023] The guide chute 2 is provided at the center of the upper end surface of the fixed guide seat 5, and a guide device 3 is provided on the inner end surface of the fixed guide seat 5 so as to slide through the guide chute 2;

[0024] The connecting device 4 is fixedly connected to the center of the upper end surface of the guide device 3.

[0025] The guide device 3 includes a fixed push rod 35, a positioning seat 33 is fixedly provided at the center of the upper end surface of the fixed push rod 35, and four groups of positioning slots 32 are equidistantly provided on the side end surface of the positioning seat 33, and four groups of cone head pins 34 are equidistantly slidably connected near the bottom of the side end surface of the positioning seat 33, and the cone head pins 34 and the positioning seat 33 are elastically fixedly connected by a return spring 31.

[0026] The connecting device 4 includes a positioning card seat 42, and four groups of plug-in card plates 41 are equidistantly arranged on the lower end face of the positioning card seat 42, and a positioning hole 49 is opened at the middle part of the inner end face of each group of plug-in card plates 41. The inner end face of the positioning card seat 42 is symmetrically and elastically slidably connected with two groups of limiting plug shafts 46 through spring clamps 45, and a connecting handle 44 is fixedly provided at the center of the outer end face of the limiting plug shaft 46. The inner end face of the positioning card seat 42 is fixedly connected with a supporting card shaft 48 through the limiting plug shaft 46, and a fixed card seat 43 is symmetrically provided on the side end face of the support card shaft 48, and a limiting handle 47 is provided on the side end face of the fixed card seat 43 located on the side.

[0027] The supporting shaft 48 is adapted to the fixed socket 43 through the limiting plug-in shaft 46 and then fixedly connected to the inner end surface of the positioning socket 42. The fixed connection between the double limiting plug-in shaft 46 and the fixed socket 43 eliminates the need for threaded connection, which not only improves the convenience of subsequent disassembly, but also prevents subsequent thread damage and jamming.

[0028] The positioning base 42 is fixedly connected to the outer end surface of the alignment base 33 by adapting the plug-in card plate 41 to the positioning slide 32 and the positioning hole 49 to the cone pin shaft 34. The positioning slide 32 can provide sufficient guiding space for the plug-in card plate 41, thereby improving the accuracy and stability of the subsequent alignment and positioning of the positioning base 42 outside the alignment base 33.

[0029] The ends of the plug-in card 41 and the cone pin 34 are both conically set. The conical setting of the plug-in card 41 and the cone pin 34 can drive the cone pin 34 to move sideways when the plug-in card 41 moves downward, thereby providing sufficient guiding space for the subsequent cone pin 34 to be inserted into the positioning hole 49.

[0030] Working principle: When the connecting device 4 is quickly docked, the user can position the positioning card seat 42 to the upper part of the positioning card seat 33 through the plug-in card plate 41, and then align the plug-in card plate 41 with the positioning slide 32, so that the positioning card seat 42 can move down steadily outside the positioning card seat 33 along the positioning slide 32. At the same time, the bottom of the plug-in card plate 41 is conical, so that when the plug-in card plate 41 moves down, the cone head pin shaft 34 can be pushed outward. Then, after the plug-in card plate 41 continues to move down, the reset spring 31 allows the four groups of cone head pin shafts 34 to be synchronously plugged into Plug in the positioning hole 49 inside the card plate 41, and then complete the limiting operation of the connecting device 4. If the support card shaft 48 needs to be installed and disassembled, the staff can hold the two sets of connecting handles 44 to pull the limiting plug shaft 46 outward, and then insert the supporting card shaft 48 into the positioning card seat 42 through the fixed card seat 43. After the positioning is completed, the two sets of connecting handles 44 can be loosened. At this time, the spring retaining ring 45 can drive the limiting plug shaft 46 to reset, so that the two sets of relative limiting plug shafts 46 can be directly plugged into the fixed card seat 43, completing the limiting operation of the support card shaft 48.
