Description

Technical Field

[0001] This utility model relates to the field of clamping mechanisms, specifically to a clamping and pushing device for the tail end of a cantilevered object. Background Technology

[0002] Clamping mechanisms are common mechanical devices. Their basic principle is to use mechanical means to clamp or release a workpiece, thereby achieving functions such as workpiece fixation, positioning, and processing. In clamping mechanisms, physical principles such as the lever principle, the friction principle, and the elastic principle also play important roles. The lever principle is used to amplify and convert force, allowing the clamping mechanism to generate a large clamping force with a small amount of force. The friction principle increases the clamping force by increasing the surface roughness and coefficient of friction of the clamps, preventing the workpiece from sliding or rotating. The elastic principle utilizes elastic materials such as springs or rubber to automatically adapt to the shape of the workpiece and apply appropriate pressure, thereby improving the clamping effect.

[0003] For example, the invention patent with application number CN202411707783.7, entitled "An Adsorption Clamping Device and Assembly Equipment", includes a first driving component and a clamping adsorption component. The first driving component drives the clamping adsorption component to move and uses the clamping adsorption component to adsorb and clamp the end of the material. However, when clamping equipment parts with a certain weight, the clamping stability of this adsorption clamping mechanism is poor and the movement accuracy is poor. Utility Model Content

[0004] The purpose of this invention is to provide a clamping and pushing device for the tail end of a cantilevered object, which aims to improve the poor stability and low movement accuracy of conventional clamping mechanisms when clamping equipment parts with a certain weight.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A clamping and pushing device for the tail end of a cantilever feature is provided for clamping the tail end of the cantilever feature. The tail end of the cantilever feature is provided with a "T"-shaped clamping block, and the two sides of the cantilever feature are provided with inclined slider mechanisms. The end face of the inclined slider mechanism is provided with a centering contact. The clamping and pushing device includes a mounting base plate, a clamping mechanism, and a telescopic pushing mechanism.

[0007] The clamping mechanism includes a drive unit, a connecting block, and a gripper unit. The drive unit is fixed on the mounting base plate. One end of the gripper unit is hinged to the drive end of the drive unit. The middle part of the gripper unit is hinged to both sides of the connecting block. The drive unit drives the other ends of the gripper units to move closer to or further away from each other.

[0008] The telescopic pushing mechanism is fixed on the mounting base plate and symmetrically arranged on both sides of the clamping mechanism.

[0009] Furthermore, it also includes a sliding base, on which the mounting base plate is movably mounted.

[0010] Furthermore, the gripper unit includes at least two sets of gripper assemblies.

[0011] The gripper assembly includes a differential link and gripping arms. One end of the differential link is hinged to the drive end, and the other end of the differential link is hinged to one end of the gripping arm. The inner sides of the middle of the two gripping arms are respectively hinged to both sides of the connecting block.

[0012] Furthermore, one end of the clamping arm is provided with a rear bending section, and the rear bending sections of both clamping arms extend inward and are respectively hinged to the other end of the two differential connecting rods.

[0013] Furthermore, the other end of the clamping arm is provided with a front bending section, and the front bending sections of the two clamping arms extend outward in a figure-eight shape, with a clamping section at the end of the front bending section.

[0014] Furthermore, the inner side of the horizontal portion of the "T"-shaped clamping block is provided with a positioning groove, and the inner side of the clamping section is provided with a clamping contact, the clamping contact being positioned corresponding to the positioning groove.

[0015] Furthermore, the number of gripper assemblies is four sets, and the top and bottom sides of the connecting block are provided with outwardly protruding hinge blocks. The inner side of the middle part of the gripping arm of the four sets of gripper assemblies is respectively hinged to the four hinge blocks.

[0016] Furthermore, a top abutment block is fixed to the side of the connecting block, and the top abutment block corresponds to the outer side of the horizontal part of the "T" shaped clamping block.

[0017] Furthermore, the sliding base includes a sliding base plate, a slide rail is fixed on the sliding base plate, a slider is slidably disposed on the slide rail, and the mounting base plate is fixed on the slider.

[0018] Furthermore, the telescopic pushing mechanism includes a mounting base and a telescopic drive cylinder. The mounting base is fixed on the mounting base plate, and the telescopic drive cylinder is fixed on the mounting base. The driving end of the telescopic drive cylinder passes through the mounting base and is fixed with a pushing contact. The telescopic drive cylinder drives the pushing contact and the centering contact to abut against each other or separate from each other.

[0019] The telescopic drive cylinders are symmetrically distributed in a figure-eight pattern on both sides of the clamping mechanism, and the distance between the drive ends of two telescopic drive cylinders is smaller than the distance between the other ends of the telescopic drive cylinders.

[0020] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0021] The telescopic pushing mechanism is located on both sides of the clamping mechanism, with its ends extending toward the cantilever feature.

[0037] Example

[0038] Please refer to Figure 1-5As shown, this embodiment provides a clamping and pushing device for the tail end of a cantilever feature object 1, used to clamp the tail end of the cantilever feature object 1. The tail end of the cantilever feature object 1 is provided with a "T"-shaped clamping block 11. Furthermore, inclined slider mechanisms 12 are provided on both sides of the cantilever feature object 1, and centering contacts 121 are provided on the end faces of the inclined slider mechanisms 12. In this embodiment, the cantilever feature object is a cantilever feature object with a cantilever structure. Specifically, the clamping and pushing device for the tail end of the cantilever feature object includes a mounting base plate 2, a clamping mechanism 3, and a telescopic pushing mechanism 4. The clamping mechanism 3 includes a driving part 32, a connecting block 33, and a gripper unit. The driving part 32 is fixed to the mounting base plate 2. One end of the gripper unit is hinged to the driving end of the driving part 32, and the middle part of the gripper unit is hinged to both sides of the connecting block 33. The driving part 32 drives the other ends of the gripper units to move closer or further apart. The telescopic pushing mechanism 4 is fixed on the mounting base plate 2 and symmetrically arranged on both sides of the clamping mechanism 3. The telescopic pushing mechanism is an active mechanism that pushes and limits the inclined slider mechanism 12 on both sides of the cantilever feature 1. In this embodiment, the driving unit 32 includes a thin cylinder; similarly, other telescopic driving devices can also be used.

[0039] The telescopic pushing mechanism 4 is located on both sides of the clamping mechanism 3, with its ends extending toward the cantilever feature 1. It pushes and limits the tail ends of the cantilever feature 1 on both sides. The driving part drives the connecting block 33 to move toward the "T"-shaped clamping block 11, so that the connecting block 33 and the "T"-shaped clamping block 11 abut against each other, and drives the gripper assembly 31 to move closer to each other, clamping the horizontal part of the "T"-shaped clamping block 11. The gripper assembly 31 applies a limiting force to the "T"-shaped clamping block 11 toward the mounting base plate 2, and the telescopic pushing mechanism 4 applies a pushing force to the tail end of the cantilever feature 1 toward the direction away from the mounting base plate 2. Together, they ensure that the cantilever feature 1 has good stability in the clamping state and improve the movement accuracy of the cantilever feature 1.

[0040] Furthermore, the clamping and pushing device for the tail end of the cantilever feature object also includes a sliding base 5, on which the mounting base plate 2 is movably mounted. The sliding base 5 controls the clamping mechanism 3 and the telescopic pushing mechanism 4 to approach the cantilever feature object 1, facilitating the clamping mechanism 3 and the telescopic pushing mechanism 4 to clamp, push, and limit the tail end of the cantilever feature object 1. In this embodiment, the sliding base 5 includes a sliding base plate 51, a slide rail 52 fixed on the sliding base plate 51, a slider 53 slidably mounted on the slide rail 52, and the mounting base plate 2 fixed on the slider 53.

[0041] Specifically, the gripper unit includes at least two gripper assemblies 31. Each gripper assembly 31 includes a differential link 312 and a gripping arm 311. One end of the differential link 312 is hinged to the drive end, and the other end of the differential link 312 is hinged to one end of the gripping arm 311. The inner sides of the middle portions of the two gripping arms 311 are respectively hinged to both sides of the connecting block 33. During the forward drive process, the drive end of the drive unit 32 drives the differential link 312 forward, and the hinge position between the differential link 312 and the gripping arm 311 moves outward, causing the hinged arm to rotate around its middle hinge position as the center. The other ends of the gripping arms 311 on both sides of the drive unit move closer to each other, thereby achieving the gripping and limiting of the "T"-shaped gripping block 11. During the backward driving process, the drive unit 32 drives the differential linkage 312 to move backward, and the junction position of the differential linkage 312 and the clamping arm 311 moves inward, so that the junction arm rotates around the central hinge position, and the other ends of the clamping arms 311 on both sides move away from each other, so that the gripper assembly 31 and the "T" shaped clamping block 11 are disengaged from each other.

[0042] In this embodiment, one end of the clamping arm 311 is provided with a rear bending section 3111. The rear bending sections 3111 of both clamping arms 311 extend inward and are respectively hinged to the other ends of the two differential connecting rods 312. That is, the two rear bending sections 3111 extend towards each other and are respectively hinged to the other ends of the two differential connecting rods 312. The rear bending section 3111 effectively shortens the driving distance of the driving unit 32, enabling the clamping of the "T"-shaped clamping block 11 with a short driving distance. Furthermore, the other end of the clamping arm 311 is provided with a front bending section 3112. The front bending sections 3112 of both clamping arms 311 extend outward in a "V" shape, and the end of the front bending section 3112 is provided with a clamping section 3113. In the clamping state, the front bending section 3112 and the tail of the cantilever feature 1 are horizontal, ensuring a tight fit between the clamping section 3113 and the "T"-shaped clamping block 11, thus improving the stability of the clamping state. In this embodiment, a positioning groove is provided on the inner side of the horizontal portion of the "T"-shaped clamping block 11, and a clamping contact 3114 is provided on the inner side of the clamping section 3113, with the clamping contact 3114 corresponding to the positioning groove. In the clamping state, the clamping contact 3114 is embedded in the positioning groove, and the position of the cantilever feature 1 is positioned using the clamping contact 3114 and the positioning groove, ensuring that the cantilever feature 1 is in the set position during the clamping state, thereby improving the accuracy of the position of the cantilever feature 1 during the movement of the cantilever feature 1. At the same time, the clamping contact 3114 limits the movement of the cantilever feature 1 inside the positioning groove, further improving the clamping effect of the gripper unit on the tail of the cantilever feature 1.

[0043] In this embodiment, there are four sets of gripper assemblies 31. The top and bottom sides of the connecting block 33 are each provided with outwardly protruding hinge blocks 331. The inner sides of the gripping arms 311 of the four sets of gripper assemblies 31 are respectively hinged to the four hinge blocks 331. The four sets of gripper assemblies 31 are distributed in pairs on the upper and lower sides of the connecting block 33, providing four-point positioning for the tail of the cantilever feature object 1, further improving the stability of the cantilever feature object 1 in the gripping state. Similarly, the number of gripper assemblies 31 can also be set to two, three, or more sets.

[0044] In this embodiment, a top abutment block 332 is fixed to the side of the connecting block 33, and the top abutment block 332 corresponds to the outer side of the horizontal part of the "T"-shaped clamping block 11. In the clamping state, the top abutment block 332 abuts against the tail of the cantilever feature 1 before the tail of the cantilever feature 1, applying an outward pushing force to the tail of the cantilever feature 1, increasing the magnitude of the pushing force provided to the cantilever feature 1, and increasing the contact area between the tail clamping and pushing device and the tail of the cantilever feature 1, further improving the stability of the cantilever feature 1 in the clamping state.

[0045] Specifically, the telescopic pushing mechanism 4 includes a mounting base 41 and a telescopic drive cylinder 42. The mounting base 41 is fixed on the mounting plate 2, and the telescopic drive cylinder 42 is fixed on the mounting base 41. The driving end of the telescopic drive cylinder 42 passes through the mounting base 41 and is fixed with a pushing contact 421. The pushing contact 421 extends through the mounting base 41 toward the centering contact 121 of the cantilever feature 1. The telescopic drive cylinder 42 drives the pushing contact 421 to abut or separate from the centering contact 121. The telescopic drive cylinder 42 drives the pushing contact 421 to move toward the cantilever feature 1 and abut against the cantilever feature 1, applying a pushing force to the cantilever feature 1. Furthermore, the telescopic drive cylinders 42 are symmetrically distributed in a figure-eight pattern on both sides of the clamping mechanism 3, and the distance between the driving ends of two telescopic drive cylinders 42 is smaller than the distance between the other ends of the telescopic drive cylinders 42. The inclined telescopic drive cylinder 42 causes the pushing contact 421 to apply the thrust to the cantilever feature 1 at an inward angle, forming a certain angle with the limiting force applied to the cantilever feature 1 by the gripper assembly 31, thus improving the clamping and limiting effect on the cantilever feature 1. In this embodiment, the end of the pushing contact 421 abuts against the floating sliders on both sides of the cantilever feature. In the limiting state, the pushing contact 421 pushes the floating sliders to retract, achieving the purpose of limiting both sides of the cantilever feature 1, further improving the limiting effect of the clamping and pushing device for the tail end of the cantilever feature 1.

[0046] In this embodiment, the cantilever feature 1 is a cantilever feature 1 that is relatively long and heavy. The clamping and pushing device for the tail end of the cantilever feature 1 in this embodiment clamps and positions the tail end of the cantilever feature 1 to meet the usage requirements of the cantilever feature 1. Similarly, it can be applied to other cantilever feature 1s that require tail end clamping.

[0047] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
