Description

Technical Field

[0001] The present invention relates to the technical field of crossbeam clamping, and particularly relates to a U-shaped crossbeam clamping mechanism. Background Art

[0002] The U-shaped crossbeam is a crossbeam with strong versatility in the frame composition, and is widely used in various light trucks, medium trucks and heavy truck frames. The U-shaped crossbeam needs to be visually inspected regularly. During the visual inspection process, the U-shaped crossbeam needs to be clamped, and different position adjustments are required to meet the inspection needs. At the same time, the processed U-shaped crossbeam also needs to be deeply cleaned before inspection. The U-shaped crossbeam mainly includes a web and two wing plates, and its structural complexity is low. At present, the U-shaped crossbeam is clamped by a pressing plate, with low clamping efficiency, inconvenient position adjustment, and the pressing plate will cover a certain surface of the U-shaped crossbeam, affecting the comprehensive inspection of the surface of the U-shaped crossbeam. Summary of the Invention

[0003] Aiming at the above defects, the purpose of the present invention is to provide a U-shaped crossbeam clamping mechanism, aiming to solve the problems of low clamping efficiency and unfavorable position adjustment of the U-shaped crossbeam in the prior art.

[0004] To solve the above technical problems, the technical solution of the present invention is:

[0005] A U-shaped crossbeam clamping mechanism includes a base, on which a first mounting seat and a second mounting seat are fixedly connected. A first rotating shaft is rotatably mounted on the first mounting seat, and a second rotating shaft is rotatably mounted on the second mounting seat. The first rotating shaft and the second rotating shaft are horizontally arranged coaxially. A first power component for driving the first rotating shaft or the second rotating shaft to rotate is mounted on the base;

[0006] A first swing arm is fixedly connected to the first rotating shaft, and a second swing arm is fixedly connected to the second rotating shaft. A first support rod parallel to the first rotating shaft or the second rotating shaft is fixedly connected between the first swing arm and the second swing arm;

[0007] A third swing arm is rotatably mounted on the first rotating shaft, and a fourth swing arm is rotatably mounted on the second rotating shaft. A second support rod parallel to the first support rod is fixedly connected between the third swing arm and the fourth swing arm;

[0008] The body of a first linear driving mechanism is hinged to the first support rod, and the driving end of the first linear driving mechanism is hinged to the second support rod;

[0009] Limit sleeves are sleeved on both the first support rod and the second support rod.

[0010] Wherein, a fifth swing arm and a sixth swing arm are hinged to the second support rod, a pressing rod parallel to the second support rod is fixedly connected between the fifth swing arm and the sixth swing arm, and a second power component for driving the fifth swing arm or the sixth swing arm to rotate around the second support rod is mounted on the third swing arm or the fourth swing arm.

[0011] Among them, the second power assembly includes a mounting bracket fixedly connected to the third swing arm or the fourth swing arm. A rotary drive mechanism is installed on the mounting bracket. A connecting sleeve is sleeved on the second support rod, and the connecting sleeve is fixedly connected to the fifth swing arm or the sixth swing arm. The rotating end of the rotary drive mechanism is fixedly connected to the connecting sleeve.

[0012] Among them, a limiting sleeve is sleeved on the pressure rod.

[0013] Among them, the limiting sleeve includes a sleeve body. A locking bolt is screwed on the sleeve body, and a rotating handle is fixedly connected to the locking bolt.

[0014] Among them, the U-shaped crossbeam clamping mechanism further includes a controller. An electronic level is installed on the body of the first linear drive mechanism. The electronic level and the first power assembly are both electrically connected to the controller.

[0015] Among them, a notch is provided on the base. A sliding table is installed in the notch. A third power assembly for driving the sliding table to slide along the width direction of the base is installed on the base. A placement groove is provided on the sliding table, and a collection box is inserted in the placement groove.

[0016] Among them, the third power assembly includes two parallel guide rods slidably connected horizontally to the base. Both ends of the guide rods are fixedly connected to both sides of the sliding table through connecting plates. A second linear drive mechanism is installed on the sliding table, and the driving end of the second linear drive mechanism is fixedly connected to the base.

[0017] After adopting the above technical solution, the beneficial effects of the present invention are:

[0018] Since the U-shaped crossbeam clamping mechanism includes a base, a first mounting seat and a second mounting seat are fixedly connected to the base, a first rotating shaft is rotatably mounted on the first mounting seat, and a second rotating shaft is rotatably mounted on the second mounting seat. The first rotating shaft and the second rotating shaft are horizontally arranged coaxially. A first power assembly for driving the first rotating shaft or the second rotating shaft to rotate is mounted on the base; a first swing arm is fixedly connected to the first rotating shaft, a second swing arm is fixedly connected to the second rotating shaft, and a first support rod parallel to the first rotating shaft or the second rotating shaft is fixedly connected between the first swing arm and the second swing arm; a third swing arm is rotatably mounted on the first rotating shaft, a fourth swing arm is rotatably mounted on the second rotating shaft, and a second support rod parallel to the first support rod is fixedly connected between the third swing arm and the fourth swing arm; the body of a first linear driving mechanism is hinged to the first support rod, and the driving end of the first linear driving mechanism is hinged to the second support rod; limiting sleeves are sleeved on both the first support rod and the second support rod. During clamping, the inner wall of the web of the U-shaped crossbeam abuts against the first support rod and the second support rod, and then the first linear driving mechanism is controlled to control the second support rod to swing away from the first support rod, so that the first support rod and the second support rod are respectively pressed against the inner walls of the two wing plates of the U-shaped crossbeam, thereby realizing the inner support clamping of the U-shaped crossbeam. Limiting is formed on both ends of the U-shaped crossbeam through the limiting sleeves, thereby realizing the further fixation of the U-shaped crossbeam, and thus realizing the rapid and stable clamping of the U-shaped crossbeam. Then, the first rotating shaft is driven to rotate by a stepping motor, thereby driving the first support rod to swing, so that the U-shaped crossbeam after clamping can swing at a large angle, so that the outer side of the U-shaped crossbeam can be completely presented upward, thereby facilitating the cleaning and detection of the U-shaped crossbeam.

[0019] Since a fifth swing arm and a sixth swing arm are hinged to the second support rod, a pressure rod parallel to the second support rod is fixedly connected between the fifth swing arm and the sixth swing arm, and a second power assembly for driving the fifth swing arm or the sixth swing arm to rotate around the second support rod is mounted on the third swing arm or the fourth swing arm. When the U-shaped crossbeam is tightened between the first support rod and the second support rod, the second power assembly is used to drive the fifth swing arm to rotate, thereby realizing the rotation of the pressure rod around the second support rod, so that the pressure rod can be pressed against the outer wall of the web, avoiding the U-shaped crossbeam from swinging too large an angle to both sides after clamping and causing the U-shaped crossbeam to fall off from the clamping mechanism, thereby improving the clamping stability.

[0020] Since the U-shaped crossbeam clamping mechanism further includes a controller, an electronic level is mounted on the body of the first linear driving mechanism, and both the electronic level and the first power assembly are electrically connected to the controller. The electronic level is used to detect the levelness of the plane formed by the first support rod and the second support rod, and this plane is the position of the web. The electronic level transmits the detected levelness to the controller in real time, and the controller controls the stepping motor to adjust until the U-shaped crossbeam reaches the predetermined position, thereby realizing the accurate adjustment of the clamping position of the U-shaped crossbeam.

[0021] Since the base is provided with a notch, a sliding table is installed in the notch, a third power assembly for driving the sliding table to slide along the width direction of the base is installed on the base, a placement groove is provided on the sliding table, and a collection box is inserted in the placement groove. When the processing hole of the U-shaped cross beam is being cleaned, the scattered iron filings will enter the collection box to achieve the collection of iron filings. When the clamped U-shaped cross beam deflects to both sides, the third power assembly drives the slider to slide, so that the collection box can always be directly below the U-shaped cross beam, improving the convenience of use.

[0022] In summary, the present invention solves the problems of low clamping efficiency and unfavorable position adjustment of the U-shaped cross beam in the prior art. The present invention realizes the stable and fast clamping of the U-shaped cross beam, improves the clamping efficiency, and the present invention can realize the large-angle adjustment of the clamped U-shaped cross beam, which is convenient for the detection and cleaning of the U-shaped cross beam.

DETAILED DESCRIPTION OF THE INVENTION

[0026] The present invention will be further described below with reference to the drawings.

[0027] All directions mentioned in this specification are based on the normal working directions of a clamping mechanism for a U-shaped cross beam of the present invention, without limiting its storage and transportation directions, only representing relative position relationships, not absolute position relationships.

[0028] Such as Figure 1 and Figure 2As commonly shown, the U-shaped crossbeam 9 clamping mechanism includes a base 1. On the tabletop of the base 1, a first mounting seat 2 and a second mounting seat 3 are fixedly connected. A first rotating shaft 20 is rotatably mounted on the first mounting seat 2, and a second rotating shaft 30 is rotatably mounted on the second mounting seat 3. Both the first mounting seat 2 and the second mounting seat 3 include two mounting seat bodies. The first rotating shaft 20 or the second rotating shaft 30 is respectively connected to the two mounting seat bodies through bearings. The first rotating shaft 20 and the second rotating shaft 30 are horizontally arranged coaxially. A first power assembly 10 for driving the first rotating shaft 20 to rotate is mounted on the base 1. The first power assembly 10 includes a stepping motor and a reducer. The output shaft of the reducer is connected to the first rotating shaft 20 through a coupling.

[0029] A first swing arm 21 is fixedly connected to the first rotating shaft 20, and a second swing arm 31 is fixedly connected to the second rotating shaft 30. A first support rod 4 parallel to the first rotating shaft 20 or the second rotating shaft 30 is fixedly connected between the first swing arm 21 and the second swing arm 31; A third swing arm 22 is rotatably mounted on the first rotating shaft 20, and a fourth swing arm 32 is rotatably mounted on the second rotating shaft 30. A second support rod 5 parallel to the first support rod 4 is fixedly connected between the third swing arm 22 and the fourth swing arm 32. The first support rod 4 and the second support rod 5 are preferably round rods; The body of a first linear drive mechanism 40 is hinged to the first support rod 4, and the drive end of the first linear drive mechanism 40 is hinged to the second support rod 5; The first linear drive mechanism 40 is preferably a cylinder. The telescopic movement of this cylinder will drive the second support rod 5 to swing around the first support rod 4, thereby adjusting the distance between the first support rod 4 and the second support rod 5; Two limit sleeves 6 are respectively sleeved on the first support rod 4 and the second support rod 5.

[0030] During use, the cleaning device and the vision inspection device are both located above the base 1. The first linear drive mechanism 40 is in the initial state. The distance between the first support rod 4 and the second support rod 5 is 1 / 2 to 2 / 3 of the width of the U-shaped crossbeam 9. The U-shaped crossbeam 9 includes a web and two flange plates. The grasping mechanism places the U-shaped crossbeam 9 on the first support rod 4 and the second support rod 5, such that the inner wall of the web abuts against the first support rod 4 and the second support rod 5. Then, control the first linear drive mechanism 40 to control the second support rod 5 to swing away from the first support rod 4, such that the first support rod 4 and the second support rod 5 respectively press against the inner walls of the two flange plates, thereby realizing the inner support clamping of the U-shaped crossbeam 9. Limitations are formed on both ends of the U-shaped crossbeam 9 through the limit sleeves 6, thereby realizing the further fixation of the U-shaped crossbeam 9, and thus realizing the rapid and stable clamping of the U-shaped crossbeam 9. Then, drive the first rotating shaft 20 to rotate through the stepping motor, thereby driving the first support rod 4 to swing, realizing that the U-shaped crossbeam 9 after clamping can swing through a large angle, so that the outside of the U-shaped crossbeam 9 can be completely presented upward, thereby facilitating the cleaning and inspection of the U-shaped crossbeam 9.

[0031] In order to further improve the clamping stability of the C-shaped crossbeam 9, a fifth swing arm 50 and a sixth swing arm 51 are hinged on the second support rod 5. A pressure rod 7 is fixedly connected between the fifth swing arm 50 and the sixth swing arm 51. The pressure rod 7 is parallel to the second support rod 5. A second power assembly 8 is installed on the third swing arm 22 or the fourth swing arm 32. The second power assembly 8 drives the fifth swing arm 50 to rotate around the second support rod 5. When the C-shaped crossbeam 9 is tightened on the first support rod 4 and the second support rod 5, the second power assembly 8 drives the fifth swing arm 50 to rotate, so as to realize the rotation of the pressure rod 7 around the second support rod 5, so that the pressure rod 7 can press against the outer wall of the web, avoiding the C-shaped crossbeam 9 from swinging too much to both sides after clamping and causing the C-shaped crossbeam 9 to fall off from the clamping mechanism. Preferably, the second power assembly 8 includes a mounting bracket 80 fixedly connected to the third swing arm 22 or the fourth swing arm 32. A rotary drive mechanism 81 is installed on the mounting bracket 80. The rotary drive mechanism 81 is preferably a rotary cylinder. A connecting sleeve is sleeved on the second support rod 5. The connecting sleeve is fixedly connected to the fifth swing arm 50. The rotating end of the rotary drive mechanism 81 is fixedly connected to the connecting sleeve.

[0032] Furthermore, a limiting sleeve 6 is sleeved on the pressure rod 7. The C-shaped crossbeam 9 is reinforced by the limiting sleeve 6 on the pressure rod 7, further improving the clamping stability.

[0033] Preferably, the limiting sleeve 6 includes a sleeve body. The sleeve body is sleeved on the first support rod 4, the second support rod 5 and the pressure rod 7, so that the sleeve body can slide along the first support rod 4 or the second support rod 5 or the pressure rod 7, thereby adjusting the limiting position. A locking bolt is screwed on the sleeve body. A rotary handle is fixedly connected to the locking bolt. By rotating the rotary handle, the end of the locking bolt presses tightly on the first support rod 4 or the second support rod 5 or the pressure rod 7, so as to realize the locking after the adjustment of the sleeve body, making the limiting sleeve 6 conveniently and effectively limit the C-shaped crossbeam 9.

[0034] Further, the clamping mechanism of the C-shaped crossbeam 9 further includes a controller. An electronic level 41 is installed on the body of the first linear drive mechanism 40. The electronic level 41 and the first power assembly 10 are both electrically connected to the controller. In order to ensure the levelness of the C-shaped crossbeam 9 after clamping, the electronic level 41 is used to detect the levelness of the plane formed by the first support rod 4 and the second support rod 5. This plane is the position of the web. The electronic level 41 transmits the detected levelness to the controller in real time. The controller controls the stepper motor to adjust until the C-shaped crossbeam 9 reaches the predetermined position, thus realizing the accurate adjustment of the clamping position of the C-shaped crossbeam 9.

[0035] Furthermore, a notch 11 is provided on the base 1, a sliding table 12 is installed in the notch 11, a third power assembly 13 for driving the sliding table 12 to slide along the width direction of the base 1 is installed on the base 1, a placement groove 120 is provided on the sliding table 12, and a collection box 121 is inserted in the placement groove 120. When the processing hole of the U-shaped cross beam 9 is being cleaned, the scattered iron filings will enter the collection box 121 to achieve the collection of iron filings. When the clamped U-shaped cross beam 9 deflects to both sides, the third power assembly 13 drives the slider to slide, so that the collection box 121 can always be directly below the U-shaped cross beam 9.

[0036] Preferably, the third power assembly 13 includes two parallel guide rods 130 horizontally slidably connected to the base 1. Both ends of the guide rods 130 are fixedly connected to both sides of the sliding table 12 through connecting plates 131. The guide rods 130 achieve the stability of the sliding of the sliding table 12. A second linear driving mechanism 132 is installed on the sliding table 12. The second linear driving mechanism 132 is preferably a cylinder, and the driving end of the cylinder is fixedly connected to the base 1. When the cylinder expands and contracts, it can drive the sliding sleeve to slide along the width direction of the base 1.
