[0037] Combination Figures 1 to 7As shown together, the height-adjustable bidirectional clamping parts transfer device provided by the present invention includes a bottom platform 100 as a basic carrier, an upper platform 200 for placing the parts to be transferred, and an adjustment limit mechanism arranged on the upper platform 200; wherein, the upper platform 200 is supported above the bottom platform 100 through an adjustable height support assembly; and, limit plates 202 are respectively fixed at both ends of the upper platform 200, and the adjustment limit mechanism includes a baffle 507 slidably connected to the upper platform 200, the baffle 507 is located between the two limit plates 202, the parts to be transferred are clamped between any one of the limit plates 202 and the baffle 507, and the distance between any one of the limit plates 202 and the baffle 507 is adjustable.

[0038] In a specific embodiment of the present invention, in order to achieve a sliding connection between the baffle 507 and the upper platform 200, a T-shaped groove 504 can be opened on the upper platform 200, and a T-shaped slider 502 is slidingly connected in the T-shaped groove 504, and the upper end of the T-shaped slider 502 is connected to the baffle 507.

[0039] Furthermore, in order to achieve the sliding and fixing of the baffle 507, a screw 501 can be rotatably connected in the T-shaped slide groove 504 along the extension direction of the T-shaped slide groove 504, and a threaded hole 506 is opened on the T-shaped slider 502, and the T-shaped slider 502 is threadedly connected to the screw 501 through the threaded hole 506; and a motor 503 is arranged at one end of the upper platform 200, and the output end of the motor 503 is connected to the screw 501.

[0040] During actual use, the motor 503 drives the screw 501 to rotate, so that the T-shaped slider 502 moves along the T-shaped slide groove 504, thereby adjusting the position of the baffle 507 at its upper end. After the motor 503 stops, the position of the baffle 507 is fixed, and the baffle 507 cooperates with the limit plate 202 to clamp and fix the parts.

[0041] In addition, in order to control the motor 503, a controller 203 can be provided on the limit plate 202 close to the motor 503. The controller 203 is electrically connected to the motor 503. The motor 503 is controlled by the controller 203 to rotate forward and reverse to realize the left and right movement of the baffle 507.

[0042] In another specific embodiment of the present invention, in order to prevent parts from sliding off the upper platform 200 from the side of the baffle 507, rectangular grooves 204 can be provided on the upper platform 200, respectively located on both sides of the baffle 507, at least two through notches 205 are provided on the top of each rectangular groove 204, a support rod 206 is inserted into each through notch 205, and a cross bar 207 is connected between the tops of each support rod 206 on the same side; and a fixing hole 208 is provided on the side of the rectangular groove 204, a fixing pin 209 is inserted into the fixing hole 208, and a positioning hole corresponding to the fixing hole 208 is provided on the support rod 206, and the end of the fixing pin 209 is inserted into the positioning hole. In actual use, by plugging and pulling out the fixing pin 209 in the fixing hole 208, the support rod 206 can be fixed in a raised state to form a railing to prevent parts from sliding sideways; when not in use, the support rod 206 can be dropped to facilitate the unloading of parts from the side.

[0043] Specifically, in order to achieve height adjustment of the upper platform 200 by the adjustable height support assembly, the adjustable height support assembly may include electric hydraulic cylinders 300 disposed at four corners of the upper surface of the bottom platform 100, and connecting parts 201 are disposed at four corners of the lower surface of the upper platform 200. The upper end of each electric hydraulic cylinder 300 is rotatably connected to the corresponding connecting part 201 through a rotating shaft. By controlling the extension and contraction of the electric hydraulic cylinder 300, the lifting and height adjustment of the upper platform 200 can be achieved to meet the needs of taking and placing parts at different heights.

[0044] In order to supply power to each electric hydraulic cylinder 300 , a battery 400 may be disposed on the lower surface of the bottom platform 100 , and each electric hydraulic cylinder 300 is electrically connected to the battery 400 .

[0045] In addition, in order to facilitate the movement of the height-adjustable two-way clamping component transfer device provided by the present invention, self-locking universal wheels 102 can be provided at the four corners of the lower surface of the bottom platform 100; and a handle 101 is connected to one side of the bottom platform 100. In actual use, the staff can push the height-adjustable two-way clamping component transfer device provided by the present invention to move through the handle 101.

[0046] The height-adjustable bidirectional clamping parts transfer device provided by the present invention adopts the above-mentioned technical scheme. The electric hydraulic cylinder 300 drives the upper platform 200 to rise and fall to adjust the height, cooperates with the adjustable limit mechanism to clamp the parts, and the lateral telescopic railings to prevent the parts from slipping. It can also control unilateral tilt unloading, effectively solving the problem that the height and angle of the existing device cannot be adjusted, which brings inconvenience to the placement and unloading of parts, greatly improves the transfer efficiency and flexibility, and realizes the automation and intelligence of the electromechanical equipment processing process.

[0047] The working principle of the height-adjustable bidirectional clamping parts transfer device provided by the present invention is described in detail below:

[0048] The height-adjustable bidirectional clamping parts transfer device provided by the present invention is used to place the parts to be transferred on the upper platform 200. When placing, the parts should be neatly arranged from the side away from the baffle 507 for subsequent clamping. After the parts are placed, a command is issued through the controller 203 to control the motor 503 to rotate forward, and the motor 503 drives the screw 501 to rotate through a pair of mutually meshing gears 505. The screw 501 is connected to the threaded hole 506 on the T-shaped slider 502 by threading, so that the T-shaped slider 502 slides horizontally along the T-shaped slide groove 504, and then pushes the baffle 507 at its upper end to move in the direction of the limit plate 202 until the baffle 507 abuts against the parts and presses them. At this point, the parts are reliably clamped and limited between the baffle 507 and the limit plate 202 to prevent shaking or slipping during the subsequent transportation process.

[0049] To further improve the safety of transportation, the operator can pull the support rod 206 upward to a suitable height and insert the fixing pin 209 into the fixing hole 208 to firmly lock the raised state of the support rod 206. Multiple support rods 206 are connected as a whole through the cross bar 207 to form a safe and reliable guardrail on both sides to prevent parts from accidentally tipping over or falling during transportation.

[0050] After the preparation work is completed, the worker can push and control the entire transfer device through the handle 101 to achieve rapid transfer of parts. Thanks to the universal self-locking casters at the four corners of the bottom, the device is flexible to move and accurately positioned, and parts can be easily delivered to the target workstation even in narrow and crowded workshop aisles.

[0051] After arriving at the destination, the controller 203 can be used to remotely adjust the extension and contraction amount of the electric hydraulic cylinder 300, thereby accurately controlling the height of the upper platform 200 to match the height of the blanking station or the downstream equipment, making it convenient for workers to pick up and place parts, and significantly improving the loading and unloading efficiency. The present invention is particularly suitable for transporting workpieces that are not afraid of bumps and are easily damaged. It only needs to release the fixing pin 209 to make the support rod 206 fall back, and by controlling the extension of one side of the electric hydraulic cylinder 300, the upper platform 200 can be tilted to one side, and the parts will slide naturally under the action of gravity, smoothly and steadily, without the need for manual handling, saving time and effort.

[0052] If the space on the upper platform 200 is insufficient to accommodate all the workpieces to be transferred, the present invention also reserves the bottom platform 100 as a spare placement area, further improving the transfer efficiency and batch size. The operator only needs to flexibly allocate the placement ratio of the upper and lower platforms according to the actual situation on site to make full use of the limited transfer space.

[0053] It can be seen from the above specific embodiments that the height-adjustable bidirectional clamping component transfer device provided by the present invention has at least the following advantages:

[0054] 1. Height adjustable and flexible: The upper platform is driven by an electric hydraulic cylinder to achieve stepless adjustment, compatible with different equipment and scenarios, and can be tilted on one side for unloading, significantly improving loading and unloading efficiency.

[0055] 2. Accurate clamping and smooth transfer: Equipped with a precision adjustment limit mechanism, the motor drives the screw to drive the baffle, accurately clamping parts of different sizes, eliminating sliding and collision during transfer, and ensuring the quality of the workpiece.

[0056] 3. Safety protection, convenient and controllable: a telescopic guardrail is set to prevent parts from rolling sideways, and a special notch facilitates the lifting and quick disassembly of the guardrail, taking into account both safety and loading and unloading convenience.

[0057] 4. Flexible movement and precise positioning: It adopts self-locking universal wheels, which can be easily pushed and adjusted by one person. It can be flexibly positioned in a small space, and the self-locking function ensures stability and reliability.

[0058] As above Figures 1 to 7 The height-adjustable bidirectional clamping parts transfer device provided by the present invention is described by way of example. However, those skilled in the art should understand that various improvements can be made to the height-adjustable bidirectional clamping parts transfer device proposed by the present invention without departing from the content of the present invention.
