Description

Technical Field

[0001] This utility model relates to a fine-tuning bracket, and more particularly to a fine-tuning bracket device suitable for grippers. Background Technology

[0002] In the manufacturing of existing industrial automation equipment, if gripper devices are involved, their installation accuracy directly affects the final gripping and positioning effect. In existing technologies, the supports for gripper devices typically employ fixed installations or single-dimensional slide rail adjustment structures, which have the following drawbacks:

[0003] 1. Complex disassembly and assembly, limited adjustment dimensions. Horizontal or vertical adjustments require disassembling numerous mechanisms, hindering convenient multi-dimensional adjustments. Furthermore, the reassembly process may affect the accuracy of previous adjustments, necessitating frequent disassembly and assembly.

[0004] 2. Poor adjustment precision. The commonly used adjustment method is to adjust the slider, which is relatively complicated to operate and can only be adjusted by a single locking screw, which cannot meet the needs of high-precision adjustment.

[0005] 3. Lack of impact protection. Currently, during daily use, the gripper device is prone to rigid collision with the top structure when it rises to its limit position, resulting in component wear.

[0006] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a fine-tuning support device suitable for grippers, making it more valuable for industrial applications. Utility Model Content

[0007] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a fine-tuning support device suitable for grippers.

A left-right fine-adjustment device is mounted on the left guide block, and an up-down fine-adjustment device is mounted on the right guide block. A mounting base is connected to the front of each of the left-right and up-down fine-adjustment devices. Each left-right fine-adjustment device includes a left-right adjustment block, with horizontally paired adjustment holes on each block. A main insertion post is mounted at a corresponding position on the left guide block, and the main insertion post is inserted into the horizontal adjustment hole.

Fixing blocks are mounted on the guide columns, and the left and right guide blocks have corresponding slots at their top positions, with the fixing blocks embedded in the corresponding slots; a rubber damping layer is coated inside the slots.

[0012] Furthermore, in the aforementioned fine-tuning support device for grippers, the top mounting plate is an I-shaped structural plate, with several stop protrusions extending from both sides of the I-shaped structural plate. Buffer rods are installed with the stop protrusions facing downwards. Corresponding buffer holes are opened at the upper ends of the left-right adjusting blocks and the up-down adjusting blocks. When the left-right adjusting blocks and the up-down adjusting blocks are at their upper limit positions, the buffer rods are inserted into the buffer holes.

[0013] Furthermore, in the aforementioned fine-tuning support device for grippers, both the horizontal adjustment hole and the vertical adjustment hole are elongated holes.

[0014] Furthermore, in the aforementioned fine-tuning support device for grippers, the horizontal adjustment channel and the vertical adjustment channel are both internally threaded channels, and the horizontal adjustment set screw and the vertical adjustment set screw are both externally threaded set screws, with the pitch of the external thread ≤ 0.5mm.

[0015] Furthermore, in the aforementioned fine-tuning support device for grippers, the left and right adjustment blocks and the up and down adjustment blocks are each provided with a number of mounting threaded holes, and locking screws are connected in the mounting threaded holes.

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] like Figures 1 to 2This invention relates to a fine-tuning support device for grippers, comprising a top mounting plate 1, with a guide device 2 mounted on the upper end of the top mounting plate 1. Its unique feature is that a bearing plate 3 is symmetrically mounted below the top mounting plate 1, facilitating multi-directional suspension and meeting the multi-position allocation needs of the subsequent gripper device 28. Simultaneously, a left guide block 4 and a right guide block 5 are respectively mounted on the outer side of the bearing plate 3 via guide devices. This allows for vertical displacement adjustment of the left and right guide blocks 4 and 5 during subsequent assembly and use, preventing abnormal tilting or inward tilting and providing a better starting reference for subsequent fine-tuning. Furthermore, considering that the actual installation position of the gripper device 28 can be moderately adjusted left-right and vertically during pre-installation debugging or later maintenance to ultimately achieve a better horizontal and centered position, this invention installs a left-right fine-tuning device on the left guide block 4 and a vertical fine-tuning device on the right guide block 5. A mounting base 6 is connected to the front of the left-right and vertical fine-tuning devices.

[0030] Specifically, the left-right fine-tuning device includes left-right adjusting blocks 7, each with a pair of horizontally distributed adjusting holes 8. Simultaneously, a main insertion post 9 is installed at the corresponding position on the left guide block 4, inserting into the horizontal adjusting holes 8 to achieve engagement. Furthermore, the horizontal adjusting holes 8 extend towards the left and right outer edges of the left and right adjusting blocks 7, forming horizontal adjusting channels. Horizontal adjusting screws 10 are movably connected within these channels, with their front ends contacting the corresponding main insertion posts 9. Thus, by adjusting the left and right adjusting blocks 7 to different depths, the left and right adjusting blocks 7 can be moved left and right relative to the left guide block 4. The final locking of the left and right adjusting blocks 7 is achieved by the contact between the horizontal adjusting screws 10 and the main insertion posts 9.

[0031] Correspondingly, the up-and-down fine-tuning device used in this utility model includes an up-and-down adjusting block 11, on which vertically paired vertical adjusting holes 12 are provided. Simultaneously, a secondary insertion post 13 is installed at the corresponding position of the right guide block 5, and the secondary insertion post 13 is inserted into the vertical adjusting hole 12 to complete the connection between the up-and-down adjusting block 11 and the right guide block 5. Furthermore, considering the locking requirement after the right guide block 5 is finely adjusted, the vertical adjusting holes 12 are respectively provided with corresponding vertical adjusting channels extending through the upper and lower outer edges of the up-and-down adjusting block 11. A vertical adjusting screw 14 is movably connected within the vertical adjusting channel, and the front end of the vertical adjusting screw 14 contacts the corresponding secondary insertion post 13.

[0032] In a preferred embodiment of this invention, corresponding auxiliary connecting plates 26 are connected to both ends of the two support plates 3. This ensures that the verticality and spacing of the two support plates 3 after installation will not be significantly skewed even if affected by external forces during subsequent installation and use. Simultaneously, the auxiliary connecting plates 26 can be used to install various accessories such as auxiliary cylinders and locking devices 27, reducing the space occupied by the support plates 3. Thus, when reaching the upper limit position, the locking device 27 can transmit a stop signal to the displacement drive device, preventing the left guide block 4 and right guide block 5 from rising excessively and squeezing the top mounting plate 1.

[0033] Furthermore, the guiding device includes a slide rail 15 mounted on the outside of the support plate 3, with a slider 16 movably connected to the slide rail 15. A left guide block 4 and a right guide block 5 are mounted on the front side of the slider 16. During implementation, the left guide block 4 and right guide block 5 can be connected to the corresponding slider 16 using screws. As long as the pre-drilled holes are aligned during installation, the left guide block 4 and right guide block 5 will not be misaligned. Simultaneously, a self-lubricating coating is distributed on the inner side where the slider 16 contacts the slide rail 15. Alternatively, POM lubricating sheets can be pasted on the inner side according to different needs. This ensures smooth movement when the slider 16 drives the left guide block 4 and right guide block 5 to move up and down. Furthermore, a guide plate 17 can be extended and connected between the left guide block 4 and right guide block 5 to facilitate convenient and coordinated displacement of the two blocks. Furthermore, various types of displacement drive devices can be installed on the guide plate 17 as needed. These devices move the guide plate 17 up and down, which in turn moves the left guide block 4 and the right guide block 5 up and down, thereby driving the gripper device 28 installed on it to move up and down. The displacement drive device can also be installed in conjunction with the top mounting plate 1, by connecting its drive end to the guide plate 17, which can also control the up and down movement of the guide plate 17. In actual manufacturing, a solution where the left guide block 4, right guide block 5, and guide plate 17 are integrally formed can be selected.

[0034] In practical implementation, to ensure good linear motion performance of the gripper device 28 when vertically lowered, several guiding components are installed on the support plate 3. These guiding components are connected to the corresponding left guide block 4 and right guide block 5. Specifically, the guiding components include a mounting block 18 connected to the support plate 3. A guide post 19 is vertically mounted on the outer side of the support plate 3, and a fixing block 20 is mounted on the guide post 19. Simultaneously, the left guide block 4 and right guide block 5 have corresponding slots at their top positions, and the fixing block 20 is embedded into these slots for convenient connection. To improve the stability of the connection, a rubber damping layer can be applied to the slots to prevent unnecessary slippage of the fixing block 20 during use. Alternatively, auxiliary screws can be used to further enhance the tightness of the connection between the fixing block 20 and the corresponding left guide block 4 and right guide block 5.

[0035] During use, a buffer structure is provided to prevent the gripper device 28 from impacting the top mounting plate 1 when it rises to its limit position. Specifically, the top mounting plate 1 is an I-shaped structure plate with several stop protrusions 21 extending from both ends. A buffer rod 22 is mounted with the stop protrusions 21 facing downwards. Simultaneously, corresponding buffer holes are provided at the upper ends of the left / right adjusting block 7 and the up / down adjusting block 11. Thus, when the left / right adjusting block 7 and the up / down adjusting block 11 are at their upper limit positions, the buffer rod 22 inserts into the buffer hole, achieving effective upward stopping. Furthermore, to improve the locking and buffering effect, a rubber buffer rod 22 can be used. Alternatively, a mechanism with moderate elastic deformation, such as a spring buffer rod, can be used.

[0036] Meanwhile, to achieve a suitable fine-tuning stroke, both the horizontal adjustment hole 8 and the vertical adjustment hole 12 are elongated holes, that is, elongated holes with an approximately elliptical shape. Furthermore, both the horizontal and vertical adjustment channels are internally threaded. Correspondingly, the horizontal adjustment set screw 10 and the vertical adjustment set screw 14 are externally threaded. This allows for actual position adjustment of the horizontal adjustment set screw 10 and the vertical adjustment set screw 14 using the threaded engagement. Moreover, the pitch of the external thread is ≤0.5mm, which effectively improves the precision of the set screw adjustment.

[0037] Furthermore, to accommodate the subsequent installation of the gripper device 28, the left-right adjusting block 7 and the up-down adjusting block 11 are each provided with several threaded mounting holes, into which locking screws are connected. Simultaneously, the mounting base 6 is an L-shaped base with corresponding through holes distributed on its back plate. The locking screws pass through these through holes and into the corresponding threaded mounting holes, ensuring a secure locking connection. During implementation, the L-shaped structure allows for the hanging of the cylinder belonging to the gripper device 28 without occupying upper space, facilitating subsequent pipeline routing. Moreover, to adapt to the commonly used robotic arm interfaces for spatial positioning adjustments, the guide device 2 includes a guide base 23 connected to the top mounting plate 1. A flange 24 is mounted on the guide base 23, and an auxiliary groove 25 is provided on the flange 24. This allows for direct integration and adaptation with the robotic arm interface.

[0038] The working principle of this utility model is as follows:

[0039] After installation, install a counterweight plate, similar to the gripper device 28, on the mounting base 6. Then, using the installed displacement drive device, move the left guide block 4, right guide block 5, and guide plate 17 up and down moderately under the guidance of the guide assembly. During this process, check whether the counterweight plate is tilted at an angle or has a misalignment in the left and right spacing.

[0040] Taking the orientation of the left guide block 4 and right guide block 5 as an example, if there is an upward tilt to the right, slightly loosen the lower vertical adjustment screw 14 of the right guide block 5 while simultaneously tightening the upper vertical adjustment screw 14, causing the right guide block 5 to move slightly downward. Through continuous adjustment, it can be brought to a horizontal position. During this process, a bubble level can be installed to check the levelness.

[0041] Taking the orientation of the left guide block 4 and the right guide block 5 as an example, if there is a rightward offset, slightly loosen the right-side lateral adjustment screw 10 for the left guide block 4, and simultaneously tighten the left-side lateral adjustment screw 10, causing the left guide block 4 to move slightly to the left. After this type of calibration and adjustment, the counterweight plate is finally placed in the default centered position.

[0042] Afterwards, remove the counterweight plate and install the gripper device 28 at the reserved interface on the front of the left guide block 4 and the right guide block 5.

[0043] As can be seen from the above textual description and the accompanying drawings, the present invention has the following advantages:

[0044] 1. By cooperating with the left-right and up-down fine-tuning devices, a two-dimensional fine-tuning scheme can be formed. The left-right fine-tuning device adopts a structure that combines a horizontal adjusting screw with an elongated hole, effectively improving the horizontal position adjustment accuracy of the gripper device; the up-down fine-tuning device achieves fine adjustment in the vertical direction through the synergistic effect of the vertical adjusting hole and the threaded adjusting screw, significantly improving the installation and positioning accuracy of the gripper device.

[0045] 2. The slide rails and sliders, while ensuring stable assembly, have excellent self-lubricating properties, which can effectively reduce friction loss and noise.

[0046] 3. By utilizing the stop protrusion and the elastic buffer rod in combination, excess impact kinetic energy can be absorbed at the extreme position, avoiding impact resonance and reducing noise during use.

[0047] 4. It adopts standardized interfaces and modular design, and the connecting components such as flanges and L-shaped bases are compatible with commercially available robotic arms and gripper devices.

[0048] 5. The overall structure is simple, easy to assemble, easy to debug and maintain during use.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
