Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to a clamp that facilitates gripping profiles of different sizes. Background Technology

[0002] Palletizing fixtures for holding long profiles are specialized equipment in automated palletizing and handling systems, primarily used for stacking and transferring long, narrow workpieces such as aluminum and tubing. To accommodate different cross-sectional dimensions, these fixtures are often designed with replaceable positioning blocks or adjustment mechanisms, such as screw-type width adjustment devices; some gripper surfaces are covered with nylon or rubber pads to prevent damage to the workpiece surface.

[0003] The authorization announcement number CN223058654U discloses a multi-angle clamping engraving machine for aluminum profiles. According to its instruction manual and drawings, the clamping plate is simultaneously subjected to force and adheres to the inner wall of the adjustment groove. Under the action of anti-slip pads and anti-slip protrusions, the adjustment rod is quickly fixed. Conversely, it can be unlocked by adjusting in both longitudinal and transverse directions. This allows it to use aluminum profiles of different sizes and shapes.

[0004] However, the solution has certain limitations: 1. The fixture cannot perform the function of clamping and stacking long profiles; 2. After the fixture picks up the profiles and places them in the stacking position, the profiles are prone to positional offset. How to calibrate the offset of the placed profiles is also a problem that needs to be considered. Summary of the Invention

[0005] This utility model mainly addresses the problems existing in the profile gripping process and invents a clamp that facilitates the gripping of profiles of different sizes. The bottom of the clamping support frame is equipped with a transmission system consisting of a second guide rail, a transmission screw, and a screw nut, which enables stepless adjustment of the clamping distance between adjacent right-angle clamping plates, making it convenient to clamp profiles of different specifications and sizes.

[0006] The purpose of this invention is achieved through the following technical solution: a clamp for easily gripping profiles of different sizes, including a device frame, a clamp support assembly disposed on the device frame, the clamp support assembly being able to move up and down relative to the device frame, the end of the clamp support assembly being provided with a clamping assembly for clamping the profile, the bottom of the clamping assembly being provided with a limiting assembly for preventing the profile from falling downwards, and the side of the clamping assembly being provided with an adjusting assembly for adjusting the position of the stacked profiles.

[0007] Preferably, the clamp support assembly includes a lifting rail, rail support seats, and clamping support plates. The inside of the equipment frame is provided with an inner frame plate. The middle of the inner frame plate is provided with a lifting rail that can rise or fall relative to the inner frame plate. The surface of the inner frame plate is provided with a plurality of rail support seats for supporting the lifting rail to rise or fall. The bottom of the lifting rail is provided with a clamping support plate for fixing the clamping assembly. The sides of the plurality of rail support seats are provided with a first driving assembly for driving the lifting rail to rise or fall.

[0008] Preferably, the first drive assembly includes a toothed plate, a motor support plate, a first drive motor, and gears. The side wall of the lifting track is provided with a plurality of first guide rails and toothed plates. The side wall of each track support seat is provided with a first slider connected to the first guide rail. The motor support plate is also provided on the side wall of the track support seat. The motor support plate is provided with a first drive motor. The end of the shaft of the first drive motor is provided with a gear adapted to the toothed plate.

[0009] Preferably, the clamping assembly includes a clamping support frame, a second guide rail, a second slider, a right-angle clamping plate, and a second driving assembly. The clamping support frame is provided at the bottom of the clamping support plate, and a plurality of second guide rails are provided at the bottom of the clamping support frame. A second slider is slidably connected to each second guide rail. A right-angle clamping plate is provided at the bottom of adjacent second sliders, and adjacent right-angle clamping plates are connected by transmission through the second driving assembly.

[0010] Preferably, the second drive assembly includes a rotating shaft support, a dual-shaft reducer, a second drive motor, a transmission screw, and a screw nut. The bottom of the clamping support plate is also provided with several rotating shaft supports and dual-shaft reducers. The dual-shaft reducers are driven by the second drive motor connected to the side wall. Each rotating shaft support has a transmission screw rotatably mounted inside. The rotating shaft of the dual-shaft reducer is connected to the transmission screw via a coupling. The bottom of each right-angle clamping plate is provided with a screw nut that is connected to the transmission screw.

[0011] Preferably, the limiting assembly includes a cylinder support plate, a support guide rod, a guide rod support seat, a right-angle lifting plate, and a first cylinder element. The cylinder support plate is provided inside the right-angle clamping plate, and the support guide rod is provided on the side wall of the cylinder support plate. The support guide rod is slidably connected to the inside of the guide rod support seat. The side walls of several guide rod support seats are connected to the right-angle lifting plate. The piston rod of the first cylinder element passes through the right-angle lifting plate and the right-angle clamping plate and is connected to the cylinder support plate. The cylinder body of the first cylinder element is fixedly connected to the side wall of the right-angle lifting plate.

[0012] Preferably, the adjustment assembly includes an adjustment support plate, a second cylinder element, and a pusher plate. Each right-angle clamping plate is further provided with an adjustment support plate on its side. The left or right side of each right-angle clamping plate is used to clamp the profile.

The end of the adjustment support plate is provided with a second cylinder element, and the end of the second cylinder element is equipped with a pusher plate.

[0013] Preferably, the cylinder support plate is also provided with a limiting pin that passes through the right-angle clamping plate. The limiting pin is used to limit the minimum distance between the right-angle lifting plate and the right-angle clamping plate. This setting of the limiting pin forcibly limits the minimum safe distance between the right-angle lifting plate and the right-angle clamping plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The bottom of the clamping support frame is equipped with a transmission system consisting of a second guide rail, a transmission screw, and a screw nut to achieve stepless adjustment of the clamping distance between adjacent right-angle clamping plates, which is convenient for clamping profiles of different specifications and sizes, breaking through the single size limitation of traditional clamps. 2. When clamping several parallel profiles, there is an error in length. The first cylinder element drives the right-angle lifting plate to lift the profile, thereby preventing the shorter profile from falling. The composite constraint structure of the right-angle clamping plate and the dynamic right-angle lifting plate forms a mechanical fixation closed loop in the vertical direction, resulting in a better clamping effect. 3. After the profile falls from the right-angle lifting plate and right-angle clamping plate, there may be slight positional deviations. At this time, the piston rod of the second cylinder element drives the pusher plate to complete the adjustment of the front and back position of the profile. Then the right-angle clamping plate continues to adjust its position and readjusts the left and right position of the scattered profiles, so that the profiles can be placed neatly and accurately in the designated area.

Detailed Implementation

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: like Figure 1 , Figure 2 and Figure 3 As shown, a clamp for easily gripping profiles of different sizes includes a device frame 1 and a clamp support assembly 2 disposed on the device frame 1. The clamp support assembly 2 is capable of moving up and down relative to the device frame 1.

[0018] The clamp support assembly 2 includes a lifting rail 21, a rail support seat 22, and a clamping support plate 23. The equipment frame 1 has an inner frame plate 11 inside. The middle of the inner frame plate 11 is provided with a lifting rail 21 that can rise or fall relative to the inner frame plate 11. The surface of the inner frame plate 11 is provided with a plurality of rail support seats 22 for supporting the lifting rail 21 to rise or fall. The bottom of the lifting rail 21 is provided with a clamping support plate 23 for fixing the clamping assembly 3. The sides of the plurality of rail support seats 22 are provided with a first driving assembly 24 for driving the lifting rail 21 to rise or fall.

[0019] The first drive assembly 24 includes a toothed plate 241, a motor support plate 242, a first drive motor 243, and a gear 244. The side wall of the lifting track 21 is provided with a plurality of first guide rails 211 and toothed plates 241. The side wall of each track support 22 is provided with a first slider 221 connected to the first guide rail 211. The motor support plate 242 is also provided on the side wall of the track support 22. The first drive motor 243 is provided on the motor support plate 242. The end of the shaft of the first drive motor 243 is provided with a gear 244 adapted to the toothed plate 241.

[0020] The shaft of the first drive motor 243 drives the gear 244 to rotate during rotation. Since the first drive motor 243 is fixed to the side wall of the lifting track 21 via the motor support plate 242, the gear 244 generates a tendency to move the lifting track 21 up or down within the toothed plate 241 during rotation. During the rising or falling process, the first guide rail 211 slides on the first slider 221, thereby providing support and guidance.

[0021] In this embodiment, please continue to refer to Figure 4 , Figure 5 and Figure 6 The clamping support assembly 2 has a clamping assembly 3 at its end, which is capable of clamping the profile. The clamping assembly 3 includes a clamping support frame 31, a second guide rail 32, a second slider 33, a right-angle clamping plate 34, and a second driving assembly 35. The clamping support frame 31 is provided at the bottom of the clamping support plate 23. The bottom of the clamping support frame 31 is provided with a plurality of second guide rails 32. A second slider 33 is slidably connected to each second guide rail 32. The bottom of adjacent second sliders 33 is provided with a right-angle clamping plate 34. Adjacent right-angle clamping plates 34 are connected by transmission through the second driving assembly 35.

[0022] The second drive assembly 35 includes a shaft support 351, a dual-shaft reducer 352, a second drive motor 353, a transmission screw 354, and a screw nut 355. The bottom of the clamping support plate 23 is also provided with a plurality of shaft supports 351 and dual-shaft reducers 352. The dual-shaft reducers 352 are driven by the second drive motor 353 connected to the side wall. Each shaft support 351 has a transmission screw 354 rotatably mounted inside. The shaft of the dual-shaft reducer 352 is connected to the transmission screw 354 through a coupling. The bottom of each right-angle clamping plate 34 is provided with a screw nut 355 that is connected to the transmission screw 354.

[0023] The right-angle clamping plates 34 located on both sides of the bottom of the clamping support frame 31, facing towards the center, are used to clamp the profile. Variations in the distance between adjacent right-angle clamping plates 34 allow for proper clamping of the profile. When the right-angle clamping plates 34 need to be moved, the shaft of the second drive motor 353 drives the dual-axis reducer 352. During rotation, the shafts on both sides of the dual-axis reducer 352 drive the transmission screw 354 via a coupling. The transmission screw 354 then uses the screw nut 355 to move the right-angle clamping plates 34. During movement, the second slider 33 slides on the second guide rail 32, providing support and guidance.

[0024] Please continue to refer to this. Figure 7The bottom of the clamping assembly 3 is provided with a limiting assembly 4 to prevent the profile from falling downwards, and the side of the clamping assembly 3 is provided with an adjustment assembly 5 for adjusting the position of the stacked profile.

[0025] In this embodiment, the limiting component 4 includes a cylinder support plate 41, a support guide rod 42, a guide rod support seat 43, a right-angle lifting plate 44, and a first cylinder element 45. The cylinder support plate 41 is provided inside the right-angle clamping plate 34. The support guide rod 42 is provided on the side wall of the cylinder support plate 41. The support guide rod 42 is slidably connected to the inside of the guide rod support seat 43. The right-angle lifting plates 44 are connected to the side walls of several guide rod support seats 43. The piston rod of the first cylinder element 45 passes through the right-angle lifting plate 44 and the right-angle clamping plate 34 and is connected to the cylinder support plate 41. The cylinder body of the first cylinder element 45 is fixedly connected to the side wall of the right-angle lifting plate 44. The cylinder support plate 41 is also provided with a limiting pin 46 that passes through the right-angle clamping plate 34. The limiting pin 46 is used to limit the minimum distance between the pusher plate 53 and the right-angle lifting plate 44.

[0026] Since the length of each profile may have an error of a few millimeters during the processing, it is obviously insufficient to rely solely on the right-angle clamping plates 34 on both sides of the bottom of the clamping support frame 31 for clamping. Shorter profiles are prone to slipping. Therefore, after clamping with the right-angle clamping plates 34, it is necessary to use the right-angle lifting plates 44 to abut against the bottom of the profile to limit the profile from falling.

[0027] like Figure 7 As shown, whenever the sidewalls of adjacent right-angle clamping plates 34 clamp several arranged profiles, after the right-angle clamping plates 34 move upward a certain distance under the drive of the clamping support assembly 2, the piston rod of the first cylinder element 45 retracts, causing the cylinder body of the first cylinder element 45 to drive the right-angle lifting plate 44 toward the middle position of the clamping support frame 31. The end of the right-angle lifting plate 44 gradually moves from the right side plate of the right-angle clamping plate 34 to the left side wall, thereby lifting the profiles and preventing them from falling.

[0028] In this embodiment, the adjustment assembly 5 includes an adjustment support plate 51, a second cylinder element 52, and a pusher plate 53. Each right-angle clamping plate 34 is also provided with an adjustment support plate 51 on its side. Each adjustment support plate 51 is located at the front and rear positions of the right-angle support plate. The end of the adjustment support plate 51 is provided with a second cylinder element 52, and the end of the second cylinder element 52 is equipped with a pusher plate 53.

[0029] During the process of placing the profiles clamped by the right-angle clamping plates 34 and right-angle lifting plates 44 on both sides of the bottom of the support frame 31 into the designated area, it is necessary to first adjust the height of the right-angle clamping plates 34 and right-angle lifting plates 44 using the clamping support assembly 2 so that the clamped profiles are a few millimeters above the designated area (this height is to facilitate the subsequent reset of the right-angle lifting plates 44). Then, the right-angle lifting plates 44 are reset under the action of the first cylinder element 45, so that the right-angle lifting plates 44 release the lifting of the profiles. Then, the distance between adjacent right-angle clamping plates 34 gradually increases under the transmission between the transmission screw 354 and the screw nut 355, so that these clamped profiles fall into the designated area at a height of a few millimeters.

[0030] After falling, the profile may have slight positional deviations. At this time, the piston rod of the second cylinder element 52 drives the pusher plate 53 to adjust the front and back position of the profile. Since the distance between the right-angle clamping plates 34 is the maximum length of the profile, the pusher plate 53 will definitely be able to push the outer profile. The outer profile then transmits the force to the central profile, thereby completing the adjustment of the front and back position of all profiles. Then, under the transmission between the transmission screw 354 and the screw nut 355, the right-angle clamping plates 34 readjust the left and right positions of the scattered profiles, finally achieving that the profiles are neatly and accurately placed in the designated area.

[0031] Working principle and usage of this utility model: During the clamping process, the rotating shaft of the first drive motor 243 drives the gear 244 to rotate. Since the first drive motor 243 is fixed to the side wall of the lifting rail 21 by the motor support plate 242, the gear 244 generates a tendency to move the lifting rail 21 up or down within the toothed plate 241 during rotation. After the lifting track 21 moves to the designated height, the shaft of the second drive motor 353 drives the dual-shaft reducer 352 to start working. During the rotation of the shafts on both sides of the dual-shaft reducer 352, the transmission screw 354 can be driven to rotate through the coupling. The transmission screw 354 then uses the screw nut 355 to drive the right-angle clamping plate 34 to move. The change in the distance between adjacent right-angle clamping plates 34 can achieve the clamping of the profile. After the side walls of the adjacent right-angle clamping plates 34 clamp several arranged profiles, when the right-angle clamping plates 34 move upward a certain distance under the drive of the clamping support assembly 2, the piston rod of the first cylinder element 45 retracts, causing the cylinder body of the first cylinder element 45 to drive the right-angle lifting plate 44 toward the middle position of the clamping support frame 31. The end of the right-angle lifting plate 44 gradually moves from the right side plate of the right-angle clamping plate 34 to the left side wall, thereby lifting the profiles and preventing them from falling.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
