Description

Technical Field

[0001] This utility model relates to the field of loading and unloading clamping technology, and more specifically, to a swing-angle dual-station loading and unloading clamping device. Background Technology

[0002] Currently, traditional mechanical clamping mechanisms use cylinders to rotate and clamp at a fixed angle. The clamping part mostly uses mechanical grippers. However, they cannot directly clamp workpieces with complex or irregular shapes. Depending on the various processing requirements of the parts, if a traditional mechanical clamping mechanism cylinder is used, its rotation angle cannot meet the actual processing angle requirements. If a direct clamping method is used, it may cause some damage to the surface of the workpiece. In addition, it has problems such as high cost, large space occupation, and low production efficiency. At the same time, it cannot meet the requirements of continuous automated production when the workpiece is processed simultaneously on a machine with dual-station processing. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides a swing-angle dual-station loading and unloading clamping device. The swing angle can be flexibly set to clamp the workpiece using an electromagnet, and the workpiece floats up and down via a pin and compression spring, reducing damage to the workpiece surface.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An angular-angle dual-station loading and unloading clamping device includes a connecting frame, a sliding cylinder, a fixed suction cup assembly, a rotating suction cup assembly, and an angle guide plate. The sliding cylinder is disposed on the lower surface of the connecting frame, and a connecting plate is disposed at the bottom of the sliding cylinder. The fixed suction cup assembly and the rotating suction cup assembly are both disposed at the bottom of the sliding cylinder through the connecting plate. The fixed suction cup assembly and the rotating suction cup assembly are arranged side by side. The angle guide plate is disposed on one side of the connecting frame, and the rotating suction cup assembly is positioned to match the angle guide plate.

[0006] The fixed suction cup assembly is provided in a set. The fixed suction cup assembly includes a fixed connecting plate and a suction cup assembly. The top of the fixed connecting plate is connected to the connecting plate, and the bottom of the fixed connecting plate is connected to the suction cup assembly.

[0007] The rotating suction cup assembly is provided in two sets. The rotating suction cup assembly includes a T-shaped connecting plate, an angle adjustment seat, and a suction cup assembly. The T-shaped connecting plate is located at the bottom of the connecting plate, and the angle adjustment seat is located on the suction cup assembly. The T-shaped connecting plate and the angle adjustment seat are hinged together, and a pulley assembly is provided on the angle adjustment seat.

[0008] The T-shaped connecting plate includes a T-shaped plate and a connecting rib. The T-shaped plate is fixedly disposed at the bottom of the connecting plate, and the connecting rib is vertically disposed at the bottom of the T-shaped plate. The connecting rib is hinged to the angle adjustment seat, and a tension spring is provided between the T-shaped plate and the suction cup assembly.

[0009] The angle adjustment seat includes a clamping connecting seat and a stop plate. The clamping connecting seat is disposed on the suction cup assembly. The clamping connecting seat and the connecting rib plate are hinged by a bushing. The stop plate is disposed at the front end of the clamping connecting seat.

[0010] The suction cup assembly includes a dual-station suction cup plate, a flat pin, an outer tapered sleeve, an inner tapered sleeve, and an electromagnet plate. The dual-station suction cup plate has symmetrically arranged circular holes on both sides. The flat pin is inserted into the circular holes. An outer tapered sleeve is provided on the flat pin, and an inner tapered sleeve is provided in the circular holes. The outer tapered sleeve and the inner tapered sleeve are matched. The bottom of the flat pin is fixedly connected to the electromagnet plate. A compression spring is sleeved on the flat pin between the electromagnet plate and the dual-station suction cup plate. An electromagnet is provided at the bottom of the electromagnet plate.

[0011] The pulley assembly includes a pulley frame and a pulley. The pulley frame is fixedly mounted on the clamping connecting seat, and the pulley is mounted on the pulley frame on the side away from the clamping connecting seat. The pulley is matched with the angle guide plate.

[0012] The angle guide plate includes a height plate, a stiffener plate, and a fixing plate. The fixing plate is fixed and positioned by bolts. The height plate is connected to the fixing plate by the stiffener plate. The pulley is matched and configured with the height plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The system utilizes a cylinder to extend and retract, causing a pulley to slide on an angle guide plate, thus achieving angle swing. When the cylinder retracts, a tension spring pulls the dual-station swing-angle suction cup plate, while a stop plate returns the swing-angle suction cup assembly to its upright position. This dual-station loading and unloading clamping mechanism improves production efficiency. The electromagnet-magnetized workpiece is clamped, and the workpiece floats up and down via a pin and compression spring, minimizing damage to the workpiece surface. The swing angle can be flexibly set, enabling highly efficient clamping of electromagnet-magnetized workpieces. Attached Figure Description

Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0023] like Figures 1 to 5 As shown, a tilting dual-station loading and unloading clamping device includes a connecting frame 1, a sliding cylinder 2, a fixed suction cup assembly, a rotating suction cup assembly, and an angle guide plate 10. The sliding cylinder 2 is located on the lower surface of the connecting frame 1, and a connecting plate 3 is provided at the bottom of the sliding cylinder 2.

The angle guide plate 10 is located on one side of the connecting frame 1, and the rotating suction cup assembly is positioned to match the angle guide plate 10. The rotating suction cup assembly and the fixed suction cup assembly are arranged side by side. The angle guide plate 10 is fixedly installed according to the setting position of the connecting frame 1 and the placement position of the workpiece being gripped. The connecting frame 1 of this device is moved to the gripping origin position using a single-axis robot or a magnetically coupled rodless cylinder.

[0024] Preferably, a set of fixed suction cup assemblies is provided, which includes a fixed connecting plate 4 and a suction cup assembly 8. The top of the fixed connecting plate 4 is connected to the connecting plate 3, and the bottom of the fixed connecting plate 4 is connected to the suction cup assembly.

[0025] Preferably, the rotating suction cup assembly is provided in two sets. The rotating suction cup assembly includes a T-shaped connecting plate, an angle adjustment seat and a suction cup assembly 8. The T-shaped connecting plate is located at the bottom of the connecting plate 3, and the angle adjustment seat is located on the suction cup assembly 8. The T-shaped connecting plate and the angle adjustment seat are hinged together, and a pulley assembly is provided on the angle adjustment seat.

[0026] A rotating suction cup assembly is placed in the middle, with another rotating suction cup assembly and a separate fixed suction cup assembly on each side.

[0027] Preferably, the T-shaped connecting plate includes a T-shaped plate 51 and a connecting rib 52. The T-shaped plate 51 is fixedly disposed at the bottom of the connecting plate 3, and the connecting rib 52 is vertically disposed at the bottom of the T-shaped plate 51. The connecting rib 52 is hinged to the angle adjustment seat, and a tension spring 6 is provided between the T-shaped plate 51 and the suction cup assembly 8.

[0028] Preferably, the angle adjustment seat includes a clamping connecting seat 71 and a stop plate 73. The clamping connecting seat 71 is disposed on the suction cup assembly 8. The clamping connecting seat 71 and the connecting rib plate 52 are hinged through a bushing 72. The stop plate 73 is disposed at the front end of the clamping connecting seat 71.

[0029] Preferably, the suction cup assembly 8 includes a dual-station suction cup plate 81, a flat pin 82, an outer tapered sleeve 83, an inner tapered sleeve 84, and an electromagnet plate 85. The dual-station suction cup plate 81 has symmetrically arranged circular holes on both sides. The flat pin 82 is inserted into the circular holes. The outer tapered sleeve 83 is provided on the flat pin 82, and the inner tapered sleeve 84 is provided in the circular holes. The outer tapered sleeve 83 and the inner tapered sleeve 84 are matched. The bottom of the flat pin 82 is fixedly connected to the electromagnet plate 85. A compression spring 86 is sleeved on the flat pin 82 between the electromagnet plate 85 and the dual-station suction cup plate 81. An electromagnet 87 is provided at the bottom of the electromagnet plate 85.

[0030] Preferably, the pulley assembly includes a pulley frame 91 and a pulley 92. The pulley frame 91 is fixedly mounted on the clamping connecting seat 71, and the pulley 92 is mounted on the pulley frame 91 on the side away from the clamping connecting seat 71. The pulley 92 is matched with the angle guide plate 10.

[0031] Preferably, the angle guide plate 10 includes a height plate 11, a stiffener 12 and a fixing plate 13. The fixing plate 13 is fixed and positioned by bolts. The height plate 11 is connected to the fixing plate 13 by the stiffener 12. The pulley 92 is matched and set with the height plate 11.

[0032] During operation, a single-axis robot or a magnetically coupled rodless cylinder is used to move the loading and unloading clamping mechanism to its origin position. Assuming the right end is the loading side and the left end is the unloading side, when the slide cylinder 2 extends downwards, the right-end rotating suction cup assembly, unaffected by the angle guide plate 10, uses the tension spring 6 to pull the T-shaped plate 51 and the double-position swing angle suction cup plate 81. The stop plate 73 abuts against the rotating connecting rib plate 52, allowing the rotating suction cup assembly to vertically pick up materials from the loading bin. The middle rotating suction cup assembly, guided by the angle guide plate 10, uses the pulley... 92 slides on the angle guide plate 10, thereby allowing the middle rotating suction cup assembly to accurately remove the workpiece from the workpiece processing position at a certain angle. At the same time, the compression spring 86 between the flat pin 82 and the electromagnet plate 85 enables the electromagnet 87 to firmly attract the workpiece according to the pressure of the compression spring 86. Due to actual production errors, it is impossible to accurately guarantee that the two workpieces are at the same height. Therefore, the use of the compression spring 86 can effectively compensate for this problem. The fixed suction cup assembly at the left end does not require an angle swing mechanism and can directly and vertically pick up the material from the turntable.

[0033] When the slide cylinder 2 retracts upward, the rotating suction cup assembly at the right end rises vertically, and the pulley 92 on the rotating suction cup assembly in the middle slides on the angle guide plate 10, so that the swing suction cup assembly 8 slowly returns to the vertical state, and the fixed suction cup assembly at the left end rises vertically.

[0034] After the slide cylinder 2 retracts fully upwards, the connecting frame 1 of this device is moved laterally to the left to the second position. Then, when the slide cylinder 2 extends downwards, the rotating suction cup assembly at the right end is guided by the angle guide plate 10, and the pulley 92 slides on the angle guide plate 10, so that the rotating suction cup assembly accurately places the workpiece from the workpiece processing position at a certain angle. The rotating suction cup assembly in the middle is not affected by the angle guide plate 10. The tension spring 6 uses tension to tighten the T-shaped plate 51 and the double-station swing angle suction cup plate 81, and the stop plate 73 abuts against the rotating connecting rib plate 52, so that the rotating suction cup assembly can vertically place the workpiece on the turntable. The fixed suction cup assembly at the left end descends vertically to place the workpiece in the storage bin.

[0035] When cylinder 2 retracts upward, neither the fixed suction cup assembly nor the rotating suction cup assembly has any workpiece adsorbed. The pulley 92 on the rotating suction cup assembly at the right end slides on the angle guide plate 10, causing the rotating suction cup assembly to slowly return to the vertical state. The rotating suction cup assembly in the middle rises vertically, and the fixed suction cup assembly at the left end rises vertically.

[0036] After the slide cylinder 2 retracts fully upwards, the connecting frame 1 of this device is moved laterally to the right to the original position, and then the slide cylinder 2 descends to begin repeating the above actions.

[0037] The above description only details the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
