Description

Technical Field

[0001] This utility model belongs to the field of slide rail technology, specifically relating to an electrically driven transverse slide rail for a collaborative welding robot. Background Technology

[0002] In collaborative welding robot workstations, in order to expand the effective working range of a single robot and enable it to efficiently serve multiple welding stations, the welding robot body is usually mounted on a transverse slide rail, allowing the robot to move horizontally along the length of the slide rail. This enables welding operations across stations, significantly improving production efficiency and equipment utilization.

[0003] However, existing transverse slide rails have the following technical problems: First, the use of simple profile structures generally results in insufficient structural rigidity and bending resistance, making it difficult to withstand the large loads of welding robots (including welding torches), and prone to bending deformation, which seriously affects positioning accuracy. Second, horizontal movement relies on manual adjustment, which is cumbersome, time-consuming, labor-intensive, and has low adjustment accuracy and efficiency. Third, it is difficult to provide reliable and stable support on the mounting surface, which makes the slide rail prone to shaking when the robot moves or the load changes. This seriously affects the overall stability of the welding process, the repeatability of positioning, and the final weld quality, and also poses safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide an electrically driven transverse slide rail for collaborative welding robots, which solves the technical problems of insufficient load-bearing capacity, low degree of automation and poor installation stability in the existing technology.

[0005] This utility model discloses an electrically driven transverse slide rail for a collaborative welding robot, comprising: substrate; A sliding table is slidably disposed on the top surface of the substrate and is capable of moving along the length direction of the substrate; A rack is fixedly mounted on the substrate, and its length direction is parallel to the length direction of the substrate. The motor is fixedly mounted on the slide table; The gear is fixedly mounted on the output shaft of the motor and meshes with the rack. Multiple supporting and fixing components are arranged at intervals on the bottom surface of the substrate along the length direction of the substrate, and their positions can be adjusted independently along the length direction of the substrate.

[0006] This application significantly improves the load-bearing capacity and bending resistance through the base plate and slide table, ensuring the positioning accuracy of the robot; by driving the gear and rack through the meshing of the motor, the slide table can be driven to move horizontally, thereby realizing the automatic and precise movement of the welding robot between different workstations without manual adjustment, which significantly improves the level of production automation and efficiency; in addition, by setting multiple independently adjustable support and fixing components, it can flexibly adapt to the support requirements of different mounting surfaces, thereby ensuring installation stability.

[0007] Based on the above technical solution, the solution of this application can be further improved as follows: Preferably, the support and fixing component includes: A crossbeam is slidably disposed on the bottom surface of the substrate and is capable of moving along the length direction of the substrate; A locking assembly, installed on the crossbeam, is capable of locking the crossbeam to the base plate; Multiple magnetic bases are installed at intervals along the length of the crossbeam on the crossbeam and can be attracted and fixed to the mounting surface. This solution allows the position of the support points to be freely and independently adjusted according to the actual working conditions, thus eliminating the need for pre-planning of fixing hole positions, thereby improving installation flexibility. It also improves the speed of assembly and disassembly through magnetic attraction, without damaging the mounting surface, facilitating rapid arrangement under welding conditions. Furthermore, the surface support through the crossbeam disperses the load, improving support stability and vibration resistance.

[0008] Preferably, the locking assembly includes: Two locking units are respectively arranged on both sides of the width direction of the substrate. This solution can achieve bidirectional balanced locking of the crossbeam, thereby forming a balanced clamping couple, which can avoid skewing or torsion, and ensure that the crossbeam and the substrate can fit tightly after locking, significantly improving the locking rigidity and stability.

[0009] Preferably, the locking unit includes: The L-shaped block is fixedly installed on the top surface of the crossbeam, and the outer side of its vertical section is in contact with the side of the corresponding side of the base plate. Nuts are arranged on the inner side of the vertical section of the L-shaped block; A bolt, the shank of which passes through the vertical section of the L-shaped block and is threadedly connected to the nut; In this design, T-slots are formed on both sides of the substrate along its length in the width direction, and the bolt head is slidably placed in the T-slot on the corresponding side of the substrate. This design utilizes the sliding freedom and strong tensile strength of the T-slots, combined with the clamping force formed by the bolts and nuts and the dual positioning and force transmission function of the L-shaped blocks, to achieve rapid adjustment and secure locking of the crossbeam relative to the substrate at any position. This meets the stringent requirements for the stability and accuracy of the slide rail support system, and the external nut design improves the ease of operation and portability.

[0010] Preferably, it further includes: Two guide units are respectively disposed on both sides of the width direction of the base plate. This solution improves the motion accuracy and stability of the slide table, effectively suppresses lateral offset, torsional vibration and overturning tendency during the movement of the slide table, ensures the meshing stability of the gear and rack, and guarantees the linearity, positioning accuracy and anti-interference ability of the robot movement.

[0011] Preferably, the guiding unit includes: The guide rail is fixedly installed on the side of the substrate on the corresponding side, and its length direction is parallel to the length direction of the substrate. Multiple vertical axes are arranged at intervals and fixedly installed on the slide table; Multiple pulleys are rotatably mounted on the vertical shaft, and the outer circumference of each pulley is provided with annular grooves that engage with the guide rail. By using this solution, the engagement of the annular grooves with the guide rail achieves rolling guidance, lateral constraint, vertical support / constraint, and strong anti-overturning capability, making it suitable for industrial applications with heavy loads, high precision requirements, and the need to resist complex external forces.

[0012] Preferably, straight grooves are formed on both sides of the substrate along its length direction in the width direction. The cross-sectional shape of the straight groove is an arc greater than 180°. The guide rail has a circular cross-section and is embedded in the straight groove with an interference fit. With this solution, the guide rail is solidified into a structural extension of the substrate without stress or gap through a high-precision interference fit. This eliminates assembly errors and achieves rigid integration of the guide rail and the substrate, ensuring the absolute stability and deformation resistance of the guiding reference.

[0013] Preferably, the substrate has multiple weight-reduction channels formed along its length, and the weight-reduction channels are spaced apart along the width of the substrate. By adopting this solution, redundant mass is eliminated, lightweighting is achieved, and an equal-strength I-beam group structure is formed, thereby ensuring structural strength.

[0014] Preferably, the slide table has multiple hollowed-out grooves; by adopting this solution, the material in the non-load-bearing area is removed, the weight is improved, and the motion inertia of the slide table is reduced.

[0015] Through the above technical solution, this utility model achieves the following beneficial effects: 1. This application significantly improves the load-bearing capacity and bending resistance through the synergy of the base plate and the slide table, ensuring the positioning accuracy of the robot; by driving the gear and rack through the meshing of the motor, the slide table can be driven to move horizontally, thereby realizing the automatic and precise movement of the welding robot between different workstations without the need for manual adjustment, which significantly improves the level of production automation and efficiency; in addition, by setting multiple independently adjustable support and fixing components, it can flexibly adapt to the support requirements of different mounting surfaces, thereby ensuring installation stability; 2. This application enables the crossbeam to move along the length of the substrate, and then locks it to the substrate using a locking assembly after the crossbeam has moved to the appropriate position. This allows the position of the support point to be freely and independently adjusted according to the actual working conditions, eliminating the need for pre-planning of fixing holes and thus improving installation flexibility. Furthermore, the magnetic adsorption of the magnetic base increases the speed of assembly and disassembly without damaging the mounting surface, facilitating rapid arrangement under welding conditions. Moreover, the crossbeam provides surface support, distributing the load and improving support stability and vibration resistance. Attached Figure Description

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] In this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0021] Example: like Figure 1 As shown in the embodiment of this application, an electrically driven transverse slide rail for a collaborative welding robot is disclosed, which allows the robot to move horizontally along the length of the slide rail, thereby realizing welding operations across workstations. It has the advantages of strong load-bearing capacity, high degree of automation and good installation stability. Its specific structure includes: a base plate 1, a slide table 2, a rack 3, a motor 4, a gear 5 and multiple support and fixing components 6.

[0022] The base plate 1 is the basic support platform and reference surface of the entire slide rail. It is rectangular in shape, and its length determines the maximum range of movement of the robot.

[0023] The slide 2 is a mobile platform that carries the robot body. It is slidably disposed on the top surface of the substrate 1 and can move along the length of the substrate 1.

[0024] The rack 3 is fixedly mounted on the base plate 1, and its length direction is parallel to the length direction of the base plate 1, so as to convert the rotational motion of the gear 5 into the linear motion of the slide table 2.

[0025] Motor 4 is fixedly mounted on slide 2 and is the power source that drives the slide 2 to move. It can be a servo motor, which can provide precise speed, position and torque control.

[0026] Gear 5 is fixedly mounted on the output shaft of motor 4 and meshes with rack 3. It is an intermediate transmission element that transmits the rotational motion of motor 4 to rack 3.

[0027] Multiple support and fixing components 6 are arranged at intervals along the length of the substrate 1 on the bottom surface of the substrate 1, thereby effectively dispersing the load through multi-point support, which significantly improves rigidity, reduces deformation and vibration under load, and can be independently adjusted in position along the length of the substrate 1, so as to flexibly adapt to the support requirements of different mounting surfaces.

[0028] It should be noted that the transverse slide rail needs to be mounted on multiple protruding ribs arranged side by side at intervals. Therefore, the support and fixing component 6 plays the role of stably supporting the entire transverse slide rail on the protruding ribs, ensuring the stability of the slide rail during operation. Since the spacing and position of the protruding ribs may vary in different working scenarios, the support and fixing component 6 can be independently adjusted along the length of the base plate 1. This allows the slide rail to flexibly adjust the position of the support point according to the actual situation, thereby ensuring good contact between the slide rail and the protruding ribs and improving the adaptability and stability of the installation.

[0029] This invention significantly improves the load-bearing capacity and bending resistance through the base plate 1 and the slide table 2, ensuring the positioning accuracy of the robot. The motor 4 drives the gear 5 to mesh with the rack 3, which can drive the slide table 2 to move horizontally, thereby realizing the automatic and precise movement of the welding robot between different workstations without manual adjustment, thus improving the level of production automation and efficiency. Furthermore, by setting multiple independently adjustable support and fixing components 6, it can flexibly adapt to the support requirements of different installation surfaces, thereby ensuring installation stability.

[0030] In some embodiments, such as Figure 1 As shown, the supporting fixing component 6 includes: The crossbeam 61 is slidably disposed on the bottom surface of the substrate 1 and can move along the length direction of the substrate 1, so that the support position can be flexibly adjusted to adapt to different mounting surfaces. The length direction of the crossbeam 61 is perpendicular to the length direction of the substrate 1, thus forming a cross shape, which increases the support stability of the slide rail in the width direction. The locking assembly 62 is mounted on the crossbeam 61 and can lock the crossbeam 61 to the base plate 1. It is used to lock the crossbeam 61 to the base plate 1 after the crossbeam 61 is moved to the appropriate position, so as to prevent the crossbeam 61 from moving accidentally during use and to ensure the stability of the slide rail. Multiple magnetic bases 63 are installed at intervals along the length of the crossbeam 61 and can be attracted and fixed to the mounting surface to provide stable support and fixation.

[0031] It should be noted that the magnetic base 63 is equipped with a switch to control the magnetic attraction and release. By adjusting the attraction force of the magnetic base 63, the installation and removal of the slide rail can be facilitated. For example, on a metal mounting surface, turning on the switch of the magnetic base 63 will generate a strong magnetic force to attract it to the mounting surface; when it is necessary to move or remove the slide rail, turning off the switch will release the magnetic force.

[0032] The design of the support and fixing component 6 described above allows the position of the support point to be freely and independently adjusted according to the actual working conditions, thus eliminating the need for pre-planning of fixing hole positions, thereby improving installation flexibility. Magnetic adsorption also improves the speed of assembly and disassembly without damaging the mounting surface, facilitating rapid arrangement under welding conditions. Furthermore, the surface support provided by the crossbeam 61 distributes the load, improving support stability and vibration resistance.

[0033] Based on the above embodiments, such as Figure 1 As shown, the locking assembly 62 includes: Two locking units 621 are respectively arranged on both sides of the width direction of the substrate 1, which can realize bidirectional balanced locking of the crossbeam 61, thereby forming a balanced clamping couple, which can avoid skewing or torsion, and ensure that the crossbeam 61 and the substrate 1 can fit tightly after locking, significantly improving the locking rigidity and stability.

[0034] In this embodiment, as Figure 2 As shown, the locking unit 621 includes: L-shaped block 6211 is fixedly installed on the top surface of crossbeam 61, specifically by means of bolts, welding, etc., and the outer side of its vertical section is in contact with the side of the corresponding side of the substrate 1 to provide lateral positioning and prevent the crossbeam 61 from moving or shaking in the width direction of the substrate 1. Nut 6212 is located on the inside of the vertical section of L-shaped block 6211, allowing the operator to easily tighten or loosen it with a wrench while standing outside the base plate 1 without having to drill into the equipment. Bolt 6213, whose thread passes through the vertical section of L-shaped block 6211 and is threadedly connected to nut 6212, is used to cooperate with nut 6212 to achieve locking action; T-slots 101 are provided on both sides of the substrate 1 along its length in the width direction. The screw head of the bolt 6213 is slidably placed in the T-slot 101 on the corresponding side of the substrate 1 and cannot be pulled out directly from the opening of the slot.

[0035] The working process of the locking unit 621 described above is as follows: During position adjustment: Loosen the nuts 6212 on the two locking units 621, so that the screw head of the bolt 6213 is in a free state in the T-slot 101, and the entire support and fixing assembly 6 can slide along the length of the base plate 1; wherein, the screw head of the bolt 6213 slides in the T-slot 101, and the outer side of the vertical section of the L-shaped block 6211 slides against the side of the base plate 1. During locking: After reaching the target position, gradually tighten the nuts 6212 on the two locking units 621. When the nuts 6212 are fully tightened, the huge frictional force prevents the crossbeam 61 from moving relative to the base plate 1 in the length direction, thus achieving complete locking.

[0036] The design of the locking unit 621 described above utilizes the sliding freedom and strong tensile strength of the T-slot 101, combined with the clamping force formed by the bolt 6213 and nut 6212, and the dual positioning and force transmission function of the L-shaped block 6211, to achieve rapid adjustment and secure locking of the crossbeam 61 relative to the base plate 1 at any position. This meets the stringent requirements of collaborative welding robots for the stability and precision of the slide rail support system, and the external design of the nut 6212 improves the ease of operation and portability.

[0037] In some embodiments, such as Figure 1 As shown, it also includes: Two guide units 7 are respectively set on both sides of the width direction of the base plate 1, which improves the motion accuracy and stability of the slide table 2, effectively suppresses the lateral offset, torsional vibration and overturning tendency of the slide table 2 during the movement process, ensures the meshing stability of the gear 5 and the rack 3, and ensures the linearity of the robot's movement, positioning accuracy and anti-interference ability.

[0038] Based on the above embodiments, such as Figure 1 and Figure 2 As shown, the guide unit 7 includes: The guide rail 71 is fixedly installed on the side of the corresponding side of the base plate 1, and its length direction is parallel to the length direction of the base plate 1, and is used to provide a guide reference for the slide table 2. Multiple vertical shafts 72 are arranged at intervals and fixedly installed on the slide table 2 to serve as rotational shafts to support the pulley 73. Multiple pulleys 73 are rotatably mounted on the vertical shaft 72 in a corresponding manner, and the outer circumferential surface of the pulleys 73 is provided with annular grooves 7301 that engage with the guide rail 71, thereby forming a bidirectional constraint and restricting the degree of freedom of movement of the slide table 2 in the vertical direction and the width direction of the base plate 1.

[0039] The design of the aforementioned guide unit 7, through the engagement of the annular groove 7301 and the guide rail 71, simultaneously achieves rolling guidance, lateral constraint, vertical support / constraint, and strong anti-overturning capability, making it suitable for industrial application scenarios with heavy loads, high precision requirements, and the need to resist complex external forces.

[0040] In this embodiment, as Figure 1 As shown, straight grooves 102 are provided on both sides of the substrate 1 along its length direction in the width direction. The cross-sectional shape of the straight grooves 102 is an arc greater than 180°. The guide rail 71 has a circular cross-section and is embedded in the straight grooves 102 with an interference fit.

[0041] Through the above design, the guide rail 71 is solidified into a structural extension of the substrate 1 without stress or gap through high-precision interference fit. This eliminates assembly errors and achieves rigid integration between the guide rail 71 and the substrate 1, ensuring the absolute stability and deformation resistance of the guide reference.

[0042] In some embodiments, such as Figure 1 As shown, a plurality of weight-reduction channels 103 are provided inside the substrate 1 along its length direction, and the weight-reduction channels 103 are distributed at intervals along the width direction of the substrate 1.

[0043] By setting up the weight reduction channel 103, redundant mass was removed, lightweighting was achieved, and an equal-strength I-beam group structure was formed, thereby ensuring structural strength.

[0044] In some embodiments, such as Figure 1 As shown, the slide table 2 has multiple hollowed-out grooves 201, which remove the material in the non-load-bearing area, improve the weight reduction, and reduce the motion inertia of the slide table 2.

[0045] The workflow for this application will be further explained as follows: When the slide table 2 needs to move to the target workstation, the control system sends a command to the motor 4. After receiving the command, the motor 4 starts to rotate. The rotational torque of the motor 4 is transmitted to the gear 5 through its output shaft. The rotating gear 5 meshes with the rack 3 fixedly mounted on the base plate 1. Thus, the rotational motion of the gear 5 is forced into linear motion by the rack 3. As a result, the rolling of the gear 5 on the rack 3 will pull the entire slide table 2 to move horizontally towards the target workstation.
