In the production of automotive parts, robotic arms are needed to pick up and process parts, which improves production efficiency.

[0003] Existing robotic arms used in the production and processing of automotive parts are generally relatively fixed. During maintenance and repair, they need to be completely disassembled, which not only increases the difficulty and workload of the work, but also makes it difficult to adjust the position of the equipment. Once the equipment is installed, it cannot be adjusted, which is very inconvenient to use and increases the limitations of the equipment. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a clamping robot for automotive parts manufacturing and processing, which uses a mounting base and a fixing block to relatively fix the robot, ensuring the safety of the robot's installation and fixation, making it easy to adjust the installation position of the robot, and facilitating the disassembly of the robot during maintenance.

[0005] The technical solution adopted by the present invention to solve its technical problem is: the present invention provides a clamping robot for automobile parts production and processing, including a mounting base, a robot arm mounted on the mounting base, a clamping actuator mounted at the end of the robot arm, and the mounting base mounted on a fixed block on the ground;

[0006] The mounting base has a fixing groove, and clamping plates are symmetrically installed in the fixing groove. The fixing block is located between the two clamping plates. A locking screw is installed on the side wall of the fixing groove and is connected to the clamping plate.

[0007] The mounting base has a mounting groove, a roller is installed in the mounting groove, a pressure rod is installed in the mounting base, the lower end of the pressure rod contacts the surface of the roller, a connecting rod is installed at the upper end of the pressure rod, the connecting rod is installed on the clamping frame, and the clamping frame is fitted around the periphery of the mounting base.

[0008] The clamping plate has a movable groove, and a movable block is slidably installed in the movable groove. The thickness of the movable block is greater than the depth of the movable groove, and there is a gap between the movable blocks. A positioning block is installed on the side of the fixed block, and the positioning block is engaged in the gap between the movable blocks.

[0009] Preferably, the fixing groove is a rectangular groove, one end of the locking screw is a tightening end, the other end of the locking screw is a rotating end, the rotating end of the locking screw is connected to the clamping plate, and the two ends of the locking screw are respectively located on both sides of the fixing groove.

[0010] Preferably, there is a mutual repulsive magnetic force between the movable blocks, and the edges of the movable blocks are chamfered.

[0011] Preferably, the movable block is elastic, the movable block is an arc shape protruding towards the fixed block, and the movable block is pressed flat and the moving groove and the movable block are in an interference fit;

[0012] The movable block has a blocking protrusion on its surface facing the fixed block, and the cross-section of the blocking protrusion is a right triangle.

[0013] Preferably, the surface of the pressure rod is covered with an elastic layer, and the pressure rod is installed in the mounting base by friction.

[0014] Preferably, the rollers in the mounting groove are installed in pairs, the lower end of the pressure rod is aligned with the middle position of the pair of rollers, a wear-resistant plate is installed on the surface of the rollers, and the lower end of the pressure rod and the surface of the wear-resistant plate are roughened.

[0015] Preferably, the roller is provided with a recessed groove, and the lower end of the pressure rod is aligned with the recessed groove;

[0017] Preferably, a fixing sleeve is installed between the nut on the locking screw and the mounting base. The length of the fixing sleeve is greater than the thickness of the nut. A slot is provided on the fixing sleeve. The lower end of the retaining plate frame is inserted into the slot. The nut is located between the mounting base and the retaining plate frame.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The present invention discloses a clamping robot for manufacturing and processing automotive parts. By setting a fixed groove, a clamping plate, a locking screw, a movable groove, a movable block, and a positioning block, the locking screw drives the clamping plate to clamp the fixed block, and the positioning block is inserted into the gap between the movable blocks.

[0020] 2. The clamping robot for automotive parts manufacturing and processing described in this invention comprises a clamping frame, a fixing sleeve, a locking screw, and a clamping plate. The two ends of the locking screw are positioned on opposite sides of a fixing groove, ensuring that the clamping plate exerts force on the sidewall of the fixing groove towards the fixing block. This prevents the force from acting away from the fixing block, which could cause deformation of the fixing groove. Furthermore, after the locking screw clamps the fixing block, the lower end of the clamping frame inserts into a slot on the fixing sleeve, limiting and locking the fixing sleeve and locking screw. This prevents the locking screw from loosening due to vibration, ensuring the safety and stability of the robot's installation and fixing, and avoiding potential safety hazards.

Detailed Implementation

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] like Figures 1 to 14 As shown, the present invention provides a clamping robot for manufacturing and processing automotive parts, comprising a mounting base 2, a robotic arm 6 mounted on the mounting base 2, a clamping actuator mounted at the end of the robotic arm 6, and the mounting base 2 mounted on a fixed block 11 on the ground 1.

[0039] The mounting base 2 has a fixing groove, and clamping plates 3 are symmetrically installed in the fixing groove. The fixing block 11 is located between the two clamping plates 3. A locking screw 31 is installed on the side wall of the fixing groove and is connected to the clamping plate 3.

[0040] The mounting base 2 has a mounting groove 22, a roller 4 is installed in the mounting groove 22, and a pressure rod 52 is installed in the mounting base 2. The lower end of the pressure rod 52 contacts the surface of the roller 4, and a connecting rod 51 is installed at the upper end of the pressure rod 52. The connecting rod 51 is installed on the clamping frame 5, and the clamping frame 5 is sleeved around the periphery of the mounting base 2.

[0041] The clamping plate 3 has a movable groove 32, and a movable block 33 is slidably installed in the movable groove 32. The thickness of the movable block 33 is greater than the depth of the movable groove 32, and there is a gap between the movable blocks 33. A positioning block 34 is installed on the side of the fixed block 11, and the positioning block 34 is inserted into the gap between the movable blocks 33.

[0042] In use, the mounting base 2 moves on the ground 1 in the factory through the roller 4 below. Then, the staff moves the mounting base 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 base 2 moves to the designated position, the fixing block 11 will slide into the fixing groove. Then, the staff uses a tool to tighten the locking screw 31. The locking screw 31 drives the clamping plate 3 in the fixing groove to move towards the fixing block 11 until the clamping plate 3 contacts and clamps the fixing block 11, thus completing the installation and fixing of the robot arm. After the installation is completed, the staff installs the robot arm 6 on the mounting base 2 and uses the clamping actuator installed at the end of the robot arm 6 to clamp and process the automotive parts.

[0043] The bottom surface of the fixing groove is provided with a sliding groove 21. The clamping plate 3 slides within the sliding groove 21. At the same time, before the mounting base 2 moves above the fixing block 11, a positioning block 34 is installed on the side of the fixing block 11 by screws. Then, after the operator turns the locking screw 31, the clamping plate 3 moves closer to the fixing block 11 until the clamping plate 3 contacts and clamps the fixing block 11, thereby preventing the mounting base 2 from moving relative to the fixing block 11 in the Y direction.

[0044] Meanwhile, 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, as the clamping plate 3 gradually contacts the fixed block 11, the positioning block 34 installed on the side 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 sum of the sliding space of the movable block 33 in the moving groove 32, thereby preventing the clamping plate 3 and the mounting base 2 from moving relative to the fixed block 11 in the X direction, and improving the installation and fixing effect of the mounting base 2 and the robot.

[0045] Meanwhile, after the mounting base 2 moves onto the fixed block 11, the operator presses down the clamping frame 5 around the mounting base 2, which in turn 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 squeezes the surface of the roller 4, thereby locking the roller 4 and preventing the roller 4 from being in a movable state when the clamping plate 3 clamps the fixed block 11 later. This ensures that the position of the mounting base 2 relative to the fixed block 11 is stable and accurate, further improving the installation and fixing effect of the robot.

[0046] Meanwhile, the mutual cooperation between the mounting base 2 and the fixing block 11 on the ground 1 makes the installation and fixing of the robot relatively convenient. When the position of the equipment needs to be adjusted, the robot can be easily disassembled and installed, reducing the difficulty of maintenance and servicing and reducing the workload of the staff. At the same time, due to the simple structure and shape of the fixing block 11, the robot can be easily fixed in a suitable position, making it easy to adjust the installation position of the robot to adapt to different operation needs.

[0047] Meanwhile, by inserting the positioning block 34 into the gap between the movable block 33 and the clamping plate 3 clamping the fixed block 11, the robot arm can be locked in the X and Y directions relative to the fixed block 11 when it is fixed, so as to avoid the vibration generated during the operation of the robot arm from affecting its fixing effect and causing micro-movements in the X and Y directions, which could lead to safety hazards.

[0048] In one embodiment of the present invention, the fixing groove is a rectangular groove, one end of the locking screw 31 is a tightening end, 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 the two ends of the locking screw 31 are respectively located on both sides of the fixing groove.

[0049] In order to ensure that the robot arm is firmly fixed, the clamping plate 3 exerts a relatively large force on the fixing block 11. When the clamping plate 3 exerts a pushing force on the side wall of the fixing groove away from the fixing block 11 through the locking screw 31, it is easy to cause deformation of the two side walls of the fixing groove and increase the distance between the two side walls.

[0050] Meanwhile, since the two ends of the locking screw 31 are 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 clamping plate 3 exerts a force on the side wall of the fixing groove through the locking screw in the direction of the fixing block 11. That is, the side walls on both sides of the fixing groove are subjected to a force in the direction of the fixing block 11. Therefore, when the robot is used for a long time or the installation position is changed many times, the distance between the side walls of the fixing groove is not likely to increase, thus avoiding deformation of the fixing groove, which would affect the installation and fixing effect of the mounting base 2 on the robot and avoid safety hazards during the use of the robot.

[0051] In one embodiment of the present invention, there is a mutual repulsive magnetic force between the movable blocks 33, and the edges of the movable blocks 33 are chamfered.

[0052] Because of the mutual repulsive magnetic force between the movable blocks 33, the movable blocks 33 are dispersed in the moving groove 32. In addition, with the chamfer of the edge of the movable blocks 33, the positioning block 34 can be easily inserted into the gap between the movable blocks 33 during the process of the clamping plate 3 contacting the fixed block 11. This avoids the positioning block 34 failing to be inserted smoothly into the gap between the movable blocks 33, causing the positioning block 34 and the movable block 33 to overlap, which would affect the fixing effect of the mounting base 2 relative to the fixed block 11 in the X direction.

[0053] Meanwhile, when the positioning block 34 is not suitable for installation on the fixed block 11, the positioning block 34 with an L-shaped cross section is snapped into the edges of both ends of the fixed block 11 in the X direction. Then, the positioning block 34 is snapped into the movable block 33 in the moving groove 32, so that the mounting base 2 is fixed and limited relative to the fixed block 11 in the X direction, avoiding the robot arm from moving in the X direction during use and causing safety hazards.

[0054] In one embodiment of the present invention, the movable block 33 is elastic, the movable block 33 is an arc shape protruding toward the fixed block 11, and after the movable block 33 is flattened, the moving groove 32 and the movable block 33 are in an interference fit.

[0055] The movable block 33 has a blocking protrusion on its surface facing the fixed block 11, and the cross section of the blocking protrusion is a right triangle;

[0056] Because the movable block 33 is elastic and has an arc shape, 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 its 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. This avoids the situation where the sliding gap of the movable block 33 in the moving groove 32 is not matched with the width of the positioning block 34. In this case, the movable block 33 may cause the mounting base 2 to move slightly relative to the fixed block 11 in the X direction, which would affect the fixed installation effect of the robot and create safety hazards.

[0057] Meanwhile, since the movable block 33 is arc-shaped, the contact area between the movable block 33 and the moving groove 32 is relatively small during the clamping process of the clamping block clamping the fixed block 11. This makes it easier for the movable block 33 to move when the positioning block 34 is inserted into the gap between the movable blocks 33, thus facilitating the insertion of the positioning block 34.

[0058] Meanwhile, since the surface of the movable block 33 is provided with blocking protrusions, after the clamping plate 3 clamps the fixed block 11, the blocking protrusions will also stick to the surface of the fixed block 11. At this time, the blocking protrusions will increase the fixing effect on the fixed block 11, that is, improve the fixing effect of the mounting base 2 relative to the fixed block 11 in the Z direction, and prevent the robot from moving in the Z direction when the force is too large during the use of the robot, thus avoiding safety hazards.

[0059] In one embodiment of the present invention, the surface of the pressure rod 52 is covered with an elastic layer, and the pressure rod 52 is installed in the mounting base 2 by friction.

[0060] Due to the elastic layer on the pressure rod 52, the pressure rod 52 is in an interference fit state within the mounting base 2. That is, the pressure rod 52 can stay and be fixed at any position within the mounting base 2 through friction. Thus, when the worker presses down on the card frame 5, causing 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, ensuring the locking effect on the roller 4 and preventing the mounting base 2 from being affected by external forces, which could cause relative displacement and affect the installation and fixing effect of the mounting base 2 on the fixing block 11.

[0061] In one embodiment of the present invention, the rollers 4 in the mounting groove 22 are installed in pairs, the lower end of the pressure rod 52 is aligned with the middle position of the pair of rollers 4, a wear-resistant plate is installed on the surface of the rollers 4, and the lower end of the pressure rod 52 and the surface of the wear-resistant plate are roughened.

[0062] By installing rollers 4 in pairs, the lower end of the pressure rod 52 can easily be engaged between the rollers 4. As the rollers 4 tend to rotate, the pressure rod 52 is engaged more and more tightly, thereby improving the locking effect of the pressure rod 52 on the rollers 4. This prevents the rollers 4 from moving after the mounting base 2 has been moved to the appropriate position, which would affect the positional accuracy between the mounting base 2 and the fixing block 11, and thus affect the installation and fixing effect of the robot, creating safety hazards.

[0063] Meanwhile, a wear-resistant plate is installed on the surface of the roller 4 so that when the lower end of the pressure rod 52 contacts the roller 4 and locks the roller 4, slippage between the pressure rod 52 and the roller 4 is avoided, which would affect the locking effect of the roller 4 and prevent the mounting seat 2 from accurately stopping and fixing in the position of the fixing block 11.

[0064] In one embodiment of the present invention, the roller 4 is provided with a recessed groove 41, and the lower end of the pressure rod 52 is aligned with the recessed groove 41.

[0065] The mounting base 2 is provided with bristles 42, which surround the mounting position of the roller 4.

[0066] When the mounting base 2 moves to a suitable position on the floor 1 in the factory, the roller 4 needs to roll on the floor 1. During this process, impurities and dirt easily adhere to the surface of the roller 4. Then, 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 adhering to the surface of the roller 4, causing slippage between the pressure rod 52 and the roller 4, affecting the locking effect of the roller 4. Therefore, a recessed groove 41 is opened on the surface of the roller 4, and the diameter of the recessed 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 floor 1 adhering to the recessed groove 41, minimizing the slippage of the pressure rod 52 when locking the roller 4, and reducing the pressure when the pressure rod 52 presses down, preventing the pressure rod 52 from needing a large downward pressure to ensure the locking of the roller 4 and avoiding slippage between the pressure rod 52 and the roller 4.

[0067] At the same time, the bristles 42 surrounding the roller 4 further sweep away impurities and dirt on the ground 1, thereby avoiding or reducing the possibility of impurities and dirt adhering to the roller 4.

[0068] In one embodiment of the present invention, a fixing sleeve 53 is installed between the nut on the locking screw 31 and the mounting base 2. The length of the fixing sleeve 53 is greater than the thickness of the nut. A slot is provided on the fixing sleeve 53. The lower end of the retaining plate frame 5 is inserted into the slot. The nut is located between the mounting base 2 and the retaining plate frame 5.

[0069] Since the robotic arm is fixed and installed via the clamping plate 3 driven by the locking screw 31, and vibrations are easily generated during the operation of the robotic arm, the locking screw 31 may become loose due to vibration, affecting the fixing effect of the robotic arm and creating safety hazards. Simultaneously, a fixing sleeve 53 is installed between the nut of the locking screw 31 and the mounting base 2, so that the nut on the locking screw 31 is covered by the cylindrical part of the fixing sleeve 53. Then, the operator moves the clamping frame 5 downwards, so that the lower end of the clamping frame 5 is inserted into the slot on the fixing sleeve 53. At the same time, because all the fixing sleeves 53 are simultaneously inserted by the lower end of the clamping frame 5... The limit fixing prevents each fixed sleeve 53 from moving independently, thereby improving the limiting and fixing effect of the fixed sleeve 53. This avoids the fixed sleeve 53 and locking screw 31 from loosening due to vibration during the use of the robot, which would affect the installation and fixing effect of the robot and prevent safety hazards. At the same time, the movable installation of the part of the clamping frame 5 that inserts into the groove on the fixed sleeve 53 ensures that when the clamping frame 5 drives the pressure rod 52 to move down and lock the roller 4, the clamping frame 5 will not be inserted into the groove before the locking screw 31 is tightened, thus preventing interference with the tightening of the locking screw 31 or affecting the locking of the roller 4.

[0070] The specific workflow is as follows:

[0071] In use, the mounting base 2 moves on the ground 1 in the factory through the roller 4 below. Then, the staff moves the mounting base 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 base 2 moves to the designated position, the fixing block 11 will slide into the fixing groove. Then, the staff uses a tool to tighten the locking screw 31. The locking screw 31 drives the clamping plate 3 in the fixing groove to move towards the fixing block 11 until the clamping plate 3 contacts and clamps the fixing block 11, thus completing the installation and fixing of the robot arm. After the installation is completed, the staff installs the robot arm 6 on the mounting base 2 and uses the clamping actuator installed at the end of the robot arm 6 to clamp and process the automotive parts.

[0072] Before the mounting base 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 operator turns the locking screw 31, the clamping plate 3 moves closer to the fixing block 11 until the clamping plate 3 contacts and clamps the fixing block 11 to prevent movement in the Y direction.

[0073] As the clamping plate 3 gradually contacts the fixed block 11, the positioning block 34 installed on the side of the fixed block 11 will gradually insert into the gap between the movable blocks 33 to prevent movement in the X direction.

[0074] At the same time, after the mounting base 2 moves onto the fixed block 11, the staff presses down the card frame 5 around the mounting base 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 squeezes the surface of the roller 4, thereby locking the roller 4.

[0075] When the locking screw is tightened and the clamping plate 3 clamps the fixing block 11, the clamping plate 3 exerts a force on the side wall of the fixing groove in the direction of the fixing block 11 through the locking screw. That is, the side walls on both sides of the fixing groove are subjected to a force in the direction of the fixing block 11. Therefore, when the robot is used for a long time or the installation position is changed many times, the distance between the side walls of the fixing groove is not easy to increase, thus avoiding deformation of the fixing groove.

[0076] Due to the mutual repulsive magnetic force between the movable blocks 33, the movable blocks 33 are dispersed in the moving groove 32. In addition, with the chamfer of the edge of the movable blocks 33, the positioning block 34 can be easily inserted into the gap between the movable blocks 33 during the process of the clamping plate 3 contacting the fixed block 11.

[0077] Meanwhile, when the positioning block 34 is not suitable for installation on the fixed block 11, the positioning block 34 with an L-shaped cross section is snapped into the edges of both ends of the fixed block 11 in the X direction. Then, the positioning block 34 is snapped into the movable block 33 in the moving groove 32, so that the mounting base 2 is fixed and limited relative to the fixed block 11 in the X direction.

[0078] Since the movable block 33 is elastic and its shape 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 its 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.

[0079] Meanwhile, since the movable block 33 is arc-shaped, the contact area between the movable block 33 and the moving groove 32 is relatively small during the clamping process of the clamping block clamping the fixed block 11. 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, thereby facilitating the insertion of the positioning block 34.

[0080] Meanwhile, since the surface of the movable block 33 is provided with blocking protrusions, after the clamping plate 3 clamps the fixed block 11, the blocking protrusions will also stick to the surface of the fixed block 11. At this time, the blocking protrusions will increase the fixing effect on the fixed block 11, that is, improve the fixing effect of the mounting base 2 relative to the fixed block 11 in the Z direction.

[0081] Due to the elastic layer on the pressure rod 52, the pressure rod 52 is in an interference fit state in the mounting base 2. That is, the pressure rod 52 can stay and be fixed at any position in the mounting base 2 through friction. Thus, when the worker presses down the card 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.

[0082] By installing rollers 4 in pairs, the lower end of the pressure rod 52 can easily be engaged between the rollers 4. When the rollers 4 tend to rotate, the pressure rod 52 is engaged more and more tightly, thereby improving the locking effect of the pressure rod 52 on the rollers 4.

[0083] Meanwhile, a wear-resistant plate is installed on the surface of the roller 4 so that when the lower end of the pressure rod 52 contacts the roller 4 and locks the roller 4, slippage between the pressure rod 52 and the roller 4 is prevented.

[0084] When the lower end of the pressure rod 52 contacts the surface of the roller 4, the pressure rod 52 is easily affected by impurities and dirt attached to the surface of the roller 4, which can cause slippage between the pressure rod 52 and the roller 4. Therefore, a recessed groove 41 is opened on the surface of the roller 4, and the diameter of the recessed groove 41 is smaller than the diameter 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.

[0085] At the same time, the bristles 42 surrounding the roller 4 further sweep away the impurities and dirt on the ground 1, thereby avoiding or reducing the possibility of impurities and dirt adhering to the roller 4.

[0086] A fixing sleeve 53 is installed between the nut of the locking screw 31 and the mounting base 2, so that the nut on the locking screw 31 is covered by the cylindrical part of the fixing sleeve 53. Then, the operator moves the clamping frame 5 downward so that the lower end of the clamping frame 5 is inserted into the 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 frame 5, each fixing sleeve 53 cannot move independently, improving the limiting and fixing effect of the fixing sleeve 53 and preventing the fixing sleeve 53 and the locking screw 31 from loosening due to vibration during the use of the robot. At the same time, the part of the clamping frame 5 inserted into the slot on the fixing sleeve 53 is movable, so that when the clamping frame 5 drives the pressure rod 52 to move down and lock the roller 4, the clamping frame 5 will not be inserted into the slot before the locking screw 31 is tightened, thus interfering with the tightening of the locking screw 31 or affecting the locking of the roller 4.
