Description

Technical Field

[0001] This utility model relates to the field of clamping fixture technology, specifically to a multi-station automatic clamping fixture. Background Technology

[0002] In modern manufacturing, efficient and precise workpiece clamping technology is a key element in achieving automated production. Especially in batch processing, assembly lines, and flexible manufacturing systems, traditional manual fixtures suffer from low clamping efficiency, poor positioning consistency, and high labor intensity for workers, making it difficult to meet the demands of high-speed, high-precision production. Therefore, multi-station automatic clamping fixture technology has emerged as an important piece of equipment for improving the level of manufacturing automation.

[0003] Application number CN201520424806.3 discloses a multi-station clamping fixture, including a horizontal base. The horizontal base has several equally spaced fixing grooves corresponding to cylindrical workpieces at its center. One end of the horizontal base is provided with an eccentric cam. Between the other end of the horizontal base and the eccentric cam, a first pair of clamping rollers and a second pair of clamping rollers are sequentially arranged. Between the first pair of clamping rollers and the second pair of clamping rollers, a first pressure plate and a second pressure plate are provided for clamping several cylindrical workpieces. The ends of the first and second pressure plates are connected to the eccentric cam via connecting blocks. This design provides better clamping effect, prevents the cylindrical workpieces from slipping or loosening, and improves processing efficiency.

[0004] However, this fixture can only clamp a single type of cylindrical workpiece. The clamping rollers make it inconvenient to disassemble and replace the two clamping plates. Furthermore, each clamping operation requires manual operation to push the eccentric cam to rotate. During the clamping process, the eccentric cam is also prone to slight reversal when affected by external forces such as vibration and cutting force during processing, resulting in a decrease in clamping force. Therefore, a multi-station automatic clamping fixture is proposed. Utility Model Content

[0005] The main purpose of this utility model is to provide a multi-station automatic clamping fixture, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A multi-station automatic clamping fixture includes a base. The top of the base has a first sliding groove. There are two first sliding grooves for sliding installation of first sliders. The tops of the two first sliders are fixedly connected to the bottom of the mounting plate. One side of the mounting plate is fixedly connected to the output end of an electric cylinder. The electric cylinder is fixedly installed on one side of the base.

[0008] The mounting plate has a second sliding groove on the side away from the electric cylinder. There are two opposite second sliding grooves. The top of the mounting plate has a mounting slot. There are two mounting slots. The two mounting slots are respectively connected to the interior of the two second sliding grooves. The second sliding groove is used for sliding installation of the second slider. The second slider is fixedly connected to one end of the clamping plate.

[0009] By adopting the above technical solution, the second slider is vertically installed into the second slide groove through the mounting slot. Combined with the limiting cooperation between the pulley and the third slide groove, quick disassembly and assembly are achieved. When replacing, it is only necessary to push the clamp plate horizontally to remove the pulley from the slide groove, and it can be removed without tools.

[0010] The base positioning groove is equipped with a replaceable rubber ring. By replacing the ring with a ring of different inner diameter, it can adapt to workpieces of different diameters, thus expanding the clamping range. The overall structure takes into account both the flexible replacement of the fixture plate and the universality of workpiece positioning, which greatly improves the equipment reuse efficiency and production flexibility.

[0011] Specifically, pulleys are rotatably mounted on both the top and bottom of the second slider, and a third groove is provided on both the top and bottom of the second slide groove, the third groove being used for sliding installation of the pulleys.

[0012] By adopting the above technical solution, the pulleys at both ends of the second slider are respectively embedded in the corresponding third grooves at both ends of the second groove and roll, which not only makes the two clamping plates slide more smoothly, but also limits the second slider and prevents the second slider from being pulled out of the second groove in the wrong direction.

[0013] Specifically, the top of the base has a positioning groove, and the interior of the positioning groove is used for the installation and insertion of a rubber ring.

[0014] By adopting the above technical solution, the positioning groove is used to provide basic positioning function for the workpiece. The outer side of the rubber ring fits into the inner side of the positioning groove. The rubber ring can be used to fill the gap between the workpiece and the positioning groove. Different inner diameter rubber rings can be replaced for workpieces of different diameters.

[0015] Specifically, a first clamping roller is rotatably mounted on the top of the base, and the first clamping roller has two locations. A second clamping roller is rotatably mounted on the top of the base, and the second clamping roller has two locations.

[0016] Specifically, one side of the clamp plate is provided with a first inclined surface, a first straight surface, a second inclined surface, and a second straight surface.

[0017] By adopting the above technical solution, the first clamping roller and the second clamping roller will push the two clamping plates closer to each other until the two clamping plates clamp the workpiece in the positioning groove.

[0018] The beneficial effects of this utility model are:

[0019] (1) The multi-station automatic clamping fixture of this utility model has a second slider that is vertically installed into the second slide groove through the mounting slot. Combined with the limiting cooperation between the pulley and the third slide groove, it can be quickly disassembled and assembled. When replacing, it is only necessary to push the clamp plate horizontally to make the pulley disengage from the slide groove to remove it without tools.

[0020] (2) The multi-station automatic clamping fixture of this utility model is equipped with a replaceable rubber ring in the base positioning groove. By replacing the ring with a ring of different inner diameter, it can adapt to workpieces of different diameters, thus expanding the clamping range. The overall structure takes into account both the flexible replacement of the clamping plate and the universality of workpiece positioning, which greatly improves the equipment reuse efficiency and production flexibility.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] As one embodiment of this utility model, such as Figures 1-4As shown, the multi-station automatic clamping fixture of this utility model includes a base 8. The top of the base 8 is provided with a first sliding groove 12. There are two first sliding grooves 12, which are used for sliding installation of first sliders 13. The tops of the two first sliders 13 are fixedly connected to the bottom of the mounting plate 7. One side of the mounting plate 7 is fixedly connected to the output end of the electric cylinder 9. The electric cylinder 9 is fixedly installed on one side of the base 8.

[0029] The mounting plate 7 has a second sliding groove 17 on the side away from the electric cylinder 9. There are two opposite locations of the second sliding groove 17. The top of the mounting plate 7 has a mounting groove 19. There are two mounting grooves 19. The two mounting grooves 19 are respectively connected to the interior of the two second sliding grooves 17. The second sliding groove 17 is used for sliding installation of the second slider 15. The second slider 15 is fixedly connected to one end of the clamp plate 10.

[0030] In use, the electric cylinder 9 is activated by an external power supply. The output end of the electric cylinder 9 pushes or pulls the mounting plate 7. The mounting plate 7 slides within the two first sliding grooves 12 at the top of the base 8 via the first slider 13 fixedly connected to its bottom end, thereby achieving stable, linear movement of the mounting plate 7 and all its components relative to the base 8. This forms the basis of the entire clamping mechanism's movement. The clamping plate 10 is slidably mounted in the second sliding groove 17 of the mounting plate 7 via the second slider 15 fixed at one end. When the clamping plate 10 needs to be replaced, when the second clamping roller 4 is located on both sides of the first straight surface 3 of the clamping plate 10, the clamping plate 10 and its second slider 15 can be manually pushed away from each other along the second sliding groove 17. At this time, the second slider 15 will move to the position corresponding to the mounting groove 19, providing a channel for disassembly. During installation, the second slider 15 of the clamping plate 10 can be placed into the second sliding groove 17 through the mounting groove 19.

[0031] The present invention also includes that pulleys 16 are rotatably mounted on the top and bottom ends of the second slider 15, and a third groove 18 is provided on the top and bottom ends of the second groove 17, the third groove 18 being used for sliding installation of pulleys 16.

[0032] In use, the pulleys 16 at the top and bottom ends of the second slider 15 are respectively embedded in the corresponding third slide grooves 18 at the top and bottom ends of the second slide groove 17 and roll, which not only makes the two clamping plates 10 slide more smoothly, but also limits the second slider 15 and prevents the second slider 15 from being pulled out of the second slide groove 17 in the wrong direction.

[0033] The present invention also includes a positioning groove 11 provided at the top of the base 8, the interior of which is used for the installation and insertion of the rubber ring 14.

[0034] In use, the positioning groove 11 provides basic positioning for the workpiece. The outer side of the rubber ring 14 fits against the inner side of the positioning groove 11. The rubber ring 14 can be used to fill the gap between the workpiece and the positioning groove 11. Different inner diameter rubber rings 14 can be replaced for workpieces of different diameters.

[0035] The present invention also includes a first clamping roller 1 rotatably mounted on the top of the base 8, the first clamping roller 1 having two locations, and a second clamping roller 4 rotatably mounted on the top of the base 8, the second clamping roller 4 having two locations.

[0036] The present invention also includes a first inclined surface 2, a first straight surface 3, a second inclined surface 5, and a second straight surface 6 on one side of the clamp plate 10.

[0037] In use, the first clamping roller 1 is in contact with the surface of the first inclined surface 2, the second clamping roller 4 is in contact with the surface of the second inclined surface 5, and the distance between the two first clamping rollers 1 is smaller than the distance between the two second clamping rollers 4.

[0038] In use, the workpiece is inserted into the positioning groove 11 to allow the workpiece to be positioned on the base 8. Then, the electric cylinder 9 is started by an external power supply, which pushes the mounting plate 7 to move along the direction of the first slide groove 12. As the mounting plate 7 moves, the first clamping roller 1 and the second clamping roller 4 will push the two clamping plates 10 closer to each other until the two clamping plates 10 clamp the workpiece in the positioning groove 11.

[0039] When it is necessary to replace the clamping plate 10, simply move the electric cylinder 9 to retract the mounting plate 7 towards the electric cylinder 9. At this time, both clamping plates 10 will be moved back together. When the two second clamping rollers 4 are located on both sides of the first straight surface 3 of the two clamping plates 10, the two clamping plates 10 can be manually pushed away from each other. At this time, the second slider 15 will be exactly at the bottom surface of the mounting groove 19, and the pulley 16 at the top of the second slider 15 will exit from the third sliding groove 18. When the clamp plate 10 is slid out, simply lift it upwards to remove it. When installing the clamp plate 10, push the second slider 15 of the clamp plate 10 downwards along the direction of the mounting groove 19 so that the pulley 16 at the bottom of the second slider 15 can be engaged in the third groove 18 at the bottom end of the second groove 17. Then push the clamp plate 10 horizontally so that the pulley 16 at the top end of the second slider 15 can slide into the third groove 18 at the top end of the second groove 17. The installation is then complete.
