Specific implementation manner

[0017] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0018] As Figures 1 to 14 shown, a clamping robotic arm for the production and processing of automotive parts according to the present invention includes a mounting base 2, a robotic arm 6 is mounted on the mounting base 2, a clamping actuator is mounted at the end of the robotic arm 6, and the mounting base 2 is mounted on a fixed block 11 on the ground 1; A fixed groove is provided on the mounting base 2, clamping plates 3 are symmetrically mounted in the fixed groove, the fixed block 11 is located between the two clamping plates 3, and a locking screw 31 is mounted on the side wall of the fixed groove, and the locking screw 31 is connected to the clamping plate 3; An installation groove 22 is provided on the mounting base 2, a roller 4 is installed in the installation groove 22, a pressing rod 52 is installed in the mounting base 2, the lower end of the pressing rod 52 contacts the surface of the roller 4, a connecting rod 51 is installed at the upper end of the pressing rod 52, and the connecting rod 51 is installed on the card board frame 5, and the card board frame 5 is sleeved on the periphery of the mounting base 2; A moving groove 32 is provided on the clamping plate 3, a movable block 33 is slidably mounted in the moving groove 32, the thickness of the movable block 33 is greater than the depth of the moving groove 32, there is a gap between the movable blocks 33, and a positioning block 34 is mounted on the side surface of the fixed block 11, and the positioning block 34 is inserted into the gap between the movable blocks 33; During use, the mounting base 2 moves on the ground 1 in the factory building through the roller 4 below. After that, the staff moves the mounting base 2 to a suitable position on the ground 1. At the same time, the fixed block 11 is pre-mounted at the selected position on the ground 1. After the mounting base 2 moves to the designated position, the fixed block 11 will slide into the fixed groove. Then, the staff uses a tool to turn the locking screw 31, and drives the clamping plate 3 in the fixed groove to move towards the direction close to the fixed block 11 through the locking screw 31 until the clamping plate 3 contacts and clamps the fixed block 11, completing the installation and fixation of the robotic arm. After the installation is completed, the staff installs the robotic arm 6 on the mounting base 2, and clamps and processes the automotive parts through the clamping actuator mounted at the end of the robotic arm 6; Among them, a sliding groove 21 is formed on the bottom surface of the fixed groove. The clamping plate 3 slides in the sliding groove 21. At the same time, before the mounting seat 2 moves above the fixed block 11, a positioning block 34 is installed on the side surface of the fixed block 11 by screws. After that, when the staff twists the locking screw 31, the clamping plate 3 is driven to approach the fixed block 11 until the clamping plate 3 contacts and clamps the fixed block 11, thereby preventing the mounting seat 2 from moving relative to the fixed block 11 in the Y direction; At the same time, since the movable block 33 slides in the moving groove 32 on the clamping plate 3 and there is a sliding space for the movable block 33 in the moving groove 32, during the process that the clamping plate 3 gradually contacts the fixed block 11, the positioning block 34 installed on the side surface of the fixed block 11 will gradually insert into the gap between the movable blocks 33. At this time, the width of the positioning block 34 is equal to the total of the sliding spaces of the movable blocks 33 in the moving groove 32, thereby preventing the clamping plate 3 and the mounting seat 2 from moving relative to the fixed block 11 in the X direction and improving the installation and fixing effect of the mounting seat 2 and the manipulator; At the same time, after the mounting seat 2 moves onto the fixed block 11, the staff presses down the clamping plate frame 5 around the mounting seat 2, and then drives the pressure rod 52 to move downward through the connecting rod 51, so that the lower end of the pressure rod 52 contacts and presses the surface of the roller 4, thereby locking the roller 4 and preventing the roller 4 from being in an active state when the subsequent clamping plate 3 clamps the fixed block 11, ensuring the stable and accurate position of the mounting seat 2 relative to the fixed block 11 and further improving the installation and fixing effect of the manipulator; At the same time, through the mutual cooperation between the mounting seat 2 and the fixed block 11 on the ground 1, the installation and fixing of the manipulator are relatively convenient. Furthermore, when the position of the equipment needs to be adjusted, the manipulator can be conveniently disassembled and installed, reducing the work difficulty during maintenance and reducing the workload of the staff. At the same time, due to the simple structure and shape of the fixed block 11, the manipulator can be conveniently fixed and installed at a suitable position, facilitating the adjustment of the installation position of the manipulator to meet different operation requirements; At the same time, through the positioning block 34 being stuck into the gap between the movable blocks 33 and the clamping of the fixed block 11 by the clamping plate 3, when the manipulator is fixed, the X and Y directions of the manipulator relative to the fixed block 11 can be locked, preventing the vibration generated during the operation of the manipulator from affecting its fixing effect and generating slight movement in the X and Y directions, thus generating potential safety hazards.

[0019] As an implementation manner of the present invention, the fixed groove is a rectangular groove. One end of the locking screw 31 is a tightening end, and the other end of the locking screw 31 is a rotating end. The rotating end of the locking screw 31 is connected to the clamping plate 3, and both ends of the locking screw 31 are located on both sides of the fixed groove; To ensure firm fixation of the manipulator, the clamping plate 3 exerts a relatively large force on the fixing block 11. When the clamping plate 3 generates a thrust away from the fixing block 11 on the side wall of the fixing groove through the locking screw 31, it is easy to cause deformation of the two side walls of the fixing groove and an increase in the distance between the two side walls; At the same time, since the two ends of the locking screw 31 are respectively located on both sides of the fixing groove, when the locking screw is tightened and the clamping plate 3 clamps the fixing block 11, the acting direction of the clamping plate 3 on the side wall of the fixing groove through the locking screw is towards the fixing block 11, that is, the side walls on both sides of the fixing groove are subjected to a force towards the fixing block 11. Therefore, when the manipulator is used for a long time or the installation position is changed multiple times, the distance between the side walls of the fixing groove is not likely to increase, that is, deformation of the fixing groove is avoided, thereby affecting the installation and fixation effect of the mounting seat 2 on the manipulator and avoiding potential safety hazards during the use of the manipulator.

[0020] As an embodiment of the present invention, there is a mutually repulsive magnetic force between the movable blocks 33, and the edges of the movable blocks 33 are chamfered; Due to the mutually repulsive magnetic force between the movable blocks 33, the movable blocks 33 are dispersed and distributed relative to each other in the moving groove 32. Furthermore, in cooperation with the chamfer at the edge of the movable block 33, during the process of the clamping plate 3 contacting the fixing block 11, the positioning block 34 can be conveniently inserted into the gap between the movable blocks 33, thereby preventing the positioning block 34 from failing to be smoothly inserted into the gap between the movable blocks 33, resulting in the overlapping of the positioning block 34 and the movable blocks 33, and further affecting the fixing effect of the mounting seat 2 relative to the fixing block 11 in the X direction; At the same time, when it is not suitable to install the positioning block 34 on the fixing block 11, the positioning block 34 with an L-shaped cross-section is clamped to the edges at both ends of the fixing block 11 in the X direction. Then, the positioning block 34 is inserted into the gap between the movable blocks 33 in the moving groove 32, so as to fix and limit the mounting seat 2 relative to the fixing block 11 in the X direction, and prevent the manipulator from moving in the X direction during use, thus generating potential safety hazards.

[0021] As an embodiment of the present invention, the movable block 33 is elastic, the movable block 33 is in an arc shape protruding towards the fixing block 11, and there is an interference fit between the moving groove 32 and the movable block 33 after the movable block 33 is flattened; A blocking protrusion is provided on the surface of the movable block 33 facing the fixing block 11, and the cross-section of the blocking protrusion is a right triangle; Since the movable block 33 is elastic and the outer shape of the movable block 33 is arc-shaped, when the clamping plate 3 clamps the fixed block 11, the movable block 33 will be squeezed by the fixed block 11 and the clamping plate 3, causing the movable block 33 to be flattened from the arc shape. At this time, after the movable block 33 is flattened, an interference fit will be formed between the movable block 33 and the moving groove 32, avoiding the situation where when the sliding gap of the movable block 33 in the moving groove 32 does not match the width of the positioning block 34, the movable block 33 causes the mounting base 2 to have slight movement relative to the fixed block 11 in the X direction, affecting the fixed installation effect of the manipulator and posing a safety hazard; Meanwhile, since the movable block 33 is arc-shaped, during the process of the clamping block clamping the fixed block 11, the contact area between the movable block 33 and the moving groove 32 is relatively small. Therefore, when the positioning block 34 is inserted into the gap between the movable blocks 33, it is convenient for the movable block 33 to move, and thus it is convenient for the positioning block 34 to be inserted; Meanwhile, since there are blocking protrusions provided on the surface of the movable block 33, after the clamping plate 3 clamps the fixed block 11, the blocking protrusions will also closely adhere to the surface of the fixed block 11. At this time, the fixed effect of the fixed block 11 will be increased through the blocking protrusions, that is, the fixed effect of the mounting base 2 relative to the fixed block 11 in the Z direction will be improved, avoiding the situation where when the manipulator is under excessive force during use, the manipulator moves in the Z direction, posing a safety hazard.

[0022] As an embodiment of the present invention, an elastic layer is covered on the surface of the pressing rod 52, and the pressing rod 52 is installed in the mounting base 2 through friction; Due to the elastic layer on the pressing rod 52, the pressing rod 52 is in an interference fit state in the mounting base 2, that is, the pressing rod 52 can stay and be fixed at any position in the mounting base 2 through friction. Therefore, when the staff presses down the clamping plate frame 5 to drive the lower end of the pressing rod 52 to contact and squeeze the surface of the roller 4, the position of the pressing rod 52 is accurate and stable, ensuring the locking effect on the roller 4 and avoiding the influence of external forces, resulting in relative displacement of the mounting base 2 and affecting the installation and fixing effect of the mounting base 2 on the fixed block 11.

[0023] As an embodiment of the present invention, the rollers 4 in the installation groove 22 are installed in pairs, the lower end of the pressing rod 52 is aligned with the middle position between the paired rollers 4, wear-resistant plates are installed on the surface of the rollers 4, and the surfaces of the lower end of the pressing rod 52 and the wear-resistant plates are roughened; By installing the rollers 4 in pairs, it is easy for the lower end of the pressing rod 52 to be caught between the rollers 4. When the rollers 4 tend to rotate, the pressing rod 52 is clamped tighter and tighter, thereby improving the locking effect of the pressing rod 52 on the rollers 4, avoiding the situation where after the mounting base 2 moves to the appropriate position, the rollers 4 move, affecting the position accuracy between the mounting base 2 and the fixed block 11, and further affecting the installation and fixing effect of the manipulator, posing a safety hazard; At the same time, a wear-resistant plate is installed on the surface of the roller 4 so that the lower end of the pressure rod 52 contacts the roller 4 and locks the roller 4, thereby avoiding slippage between the pressure rod 52 and the roller 4, affecting the locking effect of the roller 4, and preventing the mounting seat 2 from accurately staying and fixing at the position of the fixing block 11.

[0024] As an embodiment of the present invention, a concave groove 41 is provided on the roller 4, and the lower end of the pressure rod 52 is aligned with the concave groove 41; The mounting seat 2 is provided with bristles 42, and the bristles 42 surround the mounting position of the roller 4; When the mounting base 2 moves to a suitable position on the ground 1 in the factory, the roller 4 needs to roll on the ground 1. During this process, impurities and dirt are easily attached to the surface of the roller 4. Later, when the lower end of the pressure rod 52 contacts the surface of the roller 4, the pressure rod 52 is easily affected by the impurities and dirt attached to the surface of the roller 4, resulting in slippage between the pressure rod 52 and the roller 4, affecting the locking effect of the roller 4. Therefore, a concave groove 41 is provided on the surface of the roller 4, so that the diameter of the concave groove 41 is smaller than the diameter of other areas on the roller 4, thereby avoiding or reducing the possibility of impurities and dirt on the ground 1 adhering to the concave groove 41, and avoiding slippage when the pressure rod 52 locks the roller 4 as much as possible. At the same time, the pressure when the pressure rod 52 is pressed down is reduced to prevent the pressure rod 52 from requiring a large downward force to ensure the locking of the roller 4 and avoid slippage between the pressure rod 52 and the roller 4. At the same time, the bristles 42 arranged around the roller 4 further sweep away the impurities and dirt on the ground 1, thereby avoiding or reducing the possibility of the impurities and dirt adhering to the roller 4.

[0025] As an embodiment of the present invention, a fixing sleeve 53 is installed between the nut on the locking screw 31 and the mounting seat 2, the length of the fixing sleeve 53 is greater than the thickness of the nut, a card slot is opened on the fixing sleeve 53, the lower end of the card plate frame 5 is inserted into the card slot, and the nut is located between the mounting seat 2 and the card plate frame 5; Since the clamping plate 3 driven by the locking screw 31 is fixedly installed on the manipulator, and vibrations are likely to occur during the operation of the manipulator, the locking screw 31 is affected by the vibrations and becomes loose, which affects the fixing effect of the manipulator and poses a safety hazard. At the same time, a fixing sleeve 53 is installed between the nut of the locking screw 31 and the mounting seat 2, so that the nut on the locking screw 31 is covered by the cylindrical part of the fixing sleeve 53. Then, the staff moves the clamping plate frame 5 downward, so that the lower end of the clamping plate frame 5 is inserted into the card slot on the fixing sleeve 53. At the same time, since each fixing sleeve 53 is limited and fixed by the lower end of the clamping plate frame 5 together, each fixing sleeve 53 cannot move independently, thereby improving the limit fixing effect on the fixing sleeve 53, preventing the fixing sleeve 53 and the locking screw 31 from being loosened due to the influence of vibrations during the use of the manipulator, affecting the installation and fixing effect of the manipulator, and avoiding potential safety hazards. At the same time, the part of the clamping plate frame 5 inserted into the card slot on the fixing sleeve 53 is movably installed. Thus, when the clamping plate frame 5 drives the pressure rod 52 to move downward to lock the roller 4, the clamping plate frame 5 will not be inserted into the card slot before the locking screw 31 is tightened, interfering with the screwing of the locking screw 31 or affecting the locking of the roller 4.

[0026] The specific working process is as follows: During use, the mounting seat 2 moves on the ground 1 in the factory building through the roller 4 below. Then, the staff moves the mounting seat 2 to a suitable position on the ground 1. At the same time, the fixing block 11 is pre-installed at the selected position on the ground 1. After the mounting seat 2 moves to the designated position, the fixing block 11 will slide into the fixing groove. Then, the staff uses a tool to turn the locking screw 31, and drives the clamping plate 3 in the fixing groove to move towards the direction close to the fixing block 11 until the clamping plate 3 contacts and clamps the fixing block 11, completing the installation and fixing of the manipulator. After the installation is completed, the staff installs the robotic arm 6 on the mounting seat 2, and uses the clamping actuator installed at the end of the robotic arm 6 to clamp and process automotive parts; Before the mounting seat 2 moves above the fixing block 11, the positioning block 34 is installed on the side of the fixing block 11 by screws. Then, after the staff turns the locking screw 31, it drives the clamping plate 3 to approach the fixing block 11 until the clamping plate 3 contacts and clamps the fixing block 11, preventing movement in the Y direction; During the process that the clamping plate 3 gradually contacts the fixing block 11, the positioning block 34 installed on the side of the fixing block 11 will gradually be inserted into the gap between the movable blocks 33, preventing movement in the X direction; At the same time, after the mounting seat 2 moves onto the fixing block 11, the staff presses down on the clamping plate frame 5 around the mounting seat 2, and then drives the pressure rod 52 to move downward through the connecting rod 51, so that the lower end of the pressure rod 52 contacts and presses the surface of the roller 4 to lock the roller 4; When tightening the locking screw and the clamping plate 3 clamps the fixing block 11, the acting force direction of the clamping plate 3 on the side wall of the fixing groove through the locking screw is towards the fixing block 11, that is, the side walls on both sides of the fixing groove are subjected to the acting force towards the fixing block 11. Therefore, when the manipulator is used for a long time or the installation position is changed multiple times, the distance between the side walls of the fixing groove is not easy to increase, that is, the deformation of the fixing groove is avoided; Due to the mutually repulsive magnetic force between the movable blocks 33, the movable blocks 33 are distributed dispersedly in the moving groove 32. Furthermore, in cooperation with the chamfers at the edges of the movable blocks 33, during the process of the clamping plate 3 contacting the fixing block 11, the positioning block 34 can be conveniently inserted into the gap between the movable blocks 33; At the same time, when it is not suitable to install the positioning block 34 on the fixing block 11, the L-shaped cross-section positioning block 34 is clamped to the edges at both ends of the fixing block 11 in the X direction. Then, the positioning block 34 is inserted into the gap between the movable blocks 33 in the moving groove 32, so that the mounting seat 2 is fixed and limited relative to the fixing block 11 in the X direction; Since the movable block 33 is elastic and the outer shape of the movable block 33 is arc-shaped, when the clamping plate 3 clamps the fixing block 11, the movable block 33 will be squeezed by the fixing block 11 and the clamping plate 3, causing the movable block 33 to be flattened from the arc shape. At this time, after the movable block 33 is flattened, an interference fit will be formed between the movable block 33 and the moving groove 32; At the same time, since the movable block 33 is arc-shaped, during the process of the clamping block clamping the fixing block 11, the contact area between the movable block 33 and the moving groove 32 is relatively small. When the positioning block 34 is inserted into the gap between the movable blocks 33, it is convenient for the movable block 33 to move, and thus it is convenient for the positioning block 34 to be inserted; At the same time, since the surface of the movable block 33 is provided with a blocking protrusion, after the clamping plate 3 clamps the fixing block 11, the blocking protrusion will also closely adhere to the surface of the fixing block 11. At this time, the fixing effect on the fixing block 11 will be increased through the blocking protrusion, that is, the fixing effect of the mounting seat 2 relative to the fixing block 11 in the Z direction is improved; Due to the elastic layer on the pressure rod 52, the pressure rod 52 is in an interference fit state in the mounting seat 2, that is, the pressure rod 52 can stay and be fixed at any position in the mounting seat 2 through friction. Therefore, when the staff presses down the clamping plate frame 5 and drives the lower end of the pressure rod 52 to contact and squeeze the surface of the roller 4, the position of the pressure rod 52 is accurate and stable; By installing the rollers 4 in pairs, it is easy for the lower end of the pressure rod 52 to be caught between the rollers 4. And when the rollers 4 tend to rotate, the pressure rod 52 is clamped tighter and tighter, improving the locking effect of the pressure rod 52 on the rollers 4; At the same time, wear-resistant plates are installed on the surface of the rollers 4, so that when the lower end of the pressure rod 52 contacts the rollers 4 and locks the rollers 4, the situation of slipping between the pressure rod 52 and the rollers 4 is avoided; When the lower end of the pressure bar 52 contacts the surface of the roller 4, the pressure bar 52 is liable to be affected by impurities and dirt adhering to the surface of the roller 4, resulting in slippage between the pressure bar 52 and the roller 4. Therefore, a recessed groove 41 is formed on the surface of the roller 4, and the diameter of the recessed groove 41 is smaller than that of other areas on the roller 4, so as to avoid or reduce the possibility of impurities and dirt on the ground 1 adhering to the recessed groove 41. Meanwhile, the impurities and dirt on the ground 1 are further swept by the bristles 42 arranged around the roller 4, so as to avoid or reduce the possibility of impurities and dirt adhering to the roller 4. A fixing sleeve 53 is installed between the nut of the locking screw 31 and the mounting seat 2, so that the nut on the locking screw 31 is covered by the cylindrical part of the fixing sleeve 53. Then, the staff moves the clamping plate frame 5 downward, so that the lower end of the clamping plate frame 5 is inserted into the card slot on the fixing sleeve 53. At the same time, since each fixing sleeve 53 is limited and fixed by the lower end of the clamping plate frame 5 together, each fixing sleeve 53 cannot move independently, improving the limiting and fixing effect on the fixing sleeve 53 and avoiding loosening of the fixing sleeve 53 and the locking screw 31 due to vibration during the use of the manipulator. Meanwhile, the part of the clamping plate frame 5 inserted into the card slot on the fixing sleeve 53 is movably installed. Thus, when the clamping plate frame 5 drives the pressure bar 52 to move downward to lock the roller 4, the clamping plate frame 5 will not be inserted into the card slot before the locking screw 31 is tightened, interfering with the screwing of the locking screw 31 or affecting the locking of the roller 4.
