Description

Technical Field

[0001] This utility model belongs to the field of clamping device technology, specifically relating to a lifting clamping device. Background Technology

[0002] The inclusion content in aluminum alloy melt refers to the amount of insoluble impurities mixed in with the aluminum alloy melt. These impurities mainly consist of metal oxides and non-metal oxides, such as aluminum oxide, calcium oxide, and magnesium oxide, and may originate from oxides generated during raw materials, additives, or the smelting process. The presence of inclusions affects the quality and yield of aluminum alloys and may also pose safety hazards to downstream production. Therefore, it is necessary to detect and analyze the inclusion content in aluminum alloy melt to ensure its quality.

[0003] Currently, most companies use the method of determining the purity of alloy melts by analyzing the impurity content at the fracture surface of the ingot. This method assesses the purity of the melt by breaking the ingot and observing the impurity content at the fracture surface. Although this method has some errors and a long feedback time, it is still widely used in practice because it provides a relatively intuitive result, helping production personnel understand the quality of the melt.

[0004] Currently, the method for detecting broken ingots is to place them directly in the detection area and then move the detection end of the detection equipment closer to the ingot. One problem with this method is that the position of the detection end of the equipment or the ingot needs to be adjusted each time to obtain a clearer image, which is not suitable for large-scale testing. Moreover, when moving the position of the detection end of the equipment, the ingot placed in the detection area is prone to displacement due to adjustment vibration. The movement of both makes it difficult to align the positions. Therefore, a clamping device is needed to fix the ingot while allowing it to be moved to fit the detection end of the equipment. Utility Model Content

[0005] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a lifting clamping device.

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

[0007] A height-adjustable clamping device includes a base, a rotating seat mounted on the top of the base, a T-shaped frustum placed on the rotating seat, a handle connected to the side of the T-shaped frustum, the T-shaped frustum and the rotating seat being clearance-fitted, a vertical rail mounted on the top of the T-shaped frustum, openings on both sides of the vertical rail, a lead screw rotatably mounted inside the vertical rail, a first screw cap mounted at the end of the lead screw, a disc threadedly connected to the lead screw, the lead screw passing through the middle of the disc, an adjusting disc rotatably mounted on the disc, the adjusting disc having symmetrical clearance slots, the width of the clearance slots being larger than the diameter of the lead screw, a first moving groove on the adjusting disc, a first threaded cylinder connected to the adjusting disc, the first threaded cylinder communicating with the first moving groove, a first screw rod threadedly connected to the first threaded cylinder, a toothed block rotatably mounted at the end of the first screw rod, the toothed block being located in the first moving groove, the shape of the toothed block matching the disc, and the outer surface of the disc having tooth grooves matching the toothed block's tooth shape;

[0008] The adjusting disc is connected to a connecting block on the other side of the first threaded cylinder. The connecting block is connected to a horizontal rail. The horizontal rail is open on one side. A double-ended screw with positive and negative threads is rotatably installed inside the horizontal rail. A second nut is installed at the end of the double-ended screw with positive and negative threads. Each of the positive and negative threads of the double-ended screw with positive and negative threads is threaded to a clamping bar. A clamping head is installed at the end of the clamping bar. An L-shaped placement plate is installed at the open end of the horizontal rail. The L-shaped placement plate has a rectangular opening corresponding to the position of the clamping bar.

[0009] Further specifying, the rotating base is provided with a fixing mechanism, which includes a rectangular platform fixedly disposed on the outside of the rotating base. The rectangular platform has a second moving groove inside, and a second threaded cylinder is connected to the outside of the rectangular platform. The second threaded cylinder communicates with the second moving groove, and a second screw rod is threadedly connected to the second threaded cylinder. An arc-shaped block is rotatably installed at the end of the second screw rod. The arc-shaped surface of the arc-shaped block is adapted to the outer surface of the T-shaped frustum. The arc-shaped block is located in the second moving groove, and the contact surface of the arc-shaped block is provided with friction texture. With this design, rotating the second screw rod can make the arc-shaped block abut against the outer surface of the T-shaped frustum, braking the T-shaped frustum by friction and preventing the T-shaped frustum from deflecting at an angle when subjected to force.

[0010] Furthermore, the power ends of the lead screw and the double-ended lead screw with positive and negative threads are equipped with motors. This design enables automated clamping and automated height adjustment.

[0011] Furthermore, the outer surface of the rotary base and the upper side of the rectangular through-hole are both provided with scale lines. This design allows the scale lines on the outer surface of the rotary base to facilitate the rapid determination of angles, and the scale lines on the upper side of the rectangular through-hole to quickly read the length or width of the clamping position of the clamped part.

[0012] Furthermore, the clamping head is plugged into and installed on the clamping strip. This design allows for the replacement of clamping heads of different specifications on the clamping strip simply by plugging and unplugging.

[0013] The beneficial effects of using this utility model are as follows:

[0014] By adopting the structural design of this utility model, the relative movement of the two clamping bars can be controlled by rotating the double-ended screw with positive and negative teeth to clamp the workpiece placed on the L-shaped placement plate. Then, rotating the screw can realize the height adjustment of the entire workpiece, achieving the purpose of lifting and clamping.

[0015] With the structural design of this utility model, the angle of the workpiece on the L-shaped placement plate can be adjusted by rotating the T-shaped frustum, making it more adaptable to use.

[0016] With the structural design of this utility model, the tilt of the workpiece on the L-shaped placement plate can be adjusted by rotating the adjustment disc, further enhancing its adaptability. Attached Figure Description

[0027] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figures 1-6 As shown, this utility model discloses a height-adjustable clamping device, including a base 1, a rotating seat 2 mounted on the top of the base 1, a T-shaped frustum 3 placed on the rotating seat 2, a handle 31 connected to the side of the T-shaped frustum 3, the T-shaped frustum 3 and the rotating seat 2 being fitted with a clearance fit, a vertical rail 4 mounted on the top of the T-shaped frustum 3, the vertical rail 4 having openings on both sides, a lead screw 5 rotatably mounted inside the vertical rail 4, a first nut 6 mounted at the end of the lead screw 5, a disc 7 threadedly connected to the lead screw 5, the lead screw 5 passing through the middle of the disc 7, and an adjusting disc 8 rotatably mounted on the disc 7. The adjusting plate 8 is symmetrically provided with clearance slots 9. The width of the clearance slots 9 is greater than the diameter of the lead screw 5. The adjusting plate 8 is provided with a first moving slot 10. The adjusting plate 8 is connected to a first threaded cylinder 11. The first threaded cylinder 11 is connected to the first moving slot 10. The first threaded cylinder 11 is threadedly connected to a first screw rod 12. A toothed block 13 is rotatably installed at the end of the first screw rod 12. The toothed block 13 is located in the first moving slot 10. The shape of the toothed block 13 matches the disc 7. The outer surface of the disc 7 is provided with tooth grooves 14 that match the tooth shape of the toothed block 13.

[0029] The adjusting disc 8 is connected to a connecting block 15 on the other side of the first threaded cylinder 11. The connecting block 15 is connected to a horizontal rail 16. The horizontal rail 16 is open on one side. A double-ended screw 17 with positive and negative threads is rotatably installed inside the horizontal rail 16. A second nut 18 is installed at the end of the double-ended screw 17 with positive and negative threads. Each of the positive and negative threads of the double-ended screw 17 is threaded to a clamping bar 19. A clamping head 20 is installed at the end of the clamping bar 19. An L-shaped placement plate 21 is installed at the open end of the horizontal rail 16. The L-shaped placement plate 21 has a rectangular opening 22 corresponding to the position of the clamping bar 19.

[0030] In this embodiment, when using a liftable clamping device, the workpiece is placed on the L-shaped placement plate 21. The shape of the L-shaped placement plate 21 provides two contact surfaces for the workpiece, which is conducive to the positioning and placement of the workpiece. Rotating the double-ended lead screw 17 with positive and negative threads causes the two clamping bars 19 on both sides of the workpiece to move relative to each other, clamping the left and right sides of the workpiece until it is clamped. This clamping method and the contact placement with the L-shaped placement plate 21 make the clamping position of multiple workpieces of the same specifications consistent, which is conducive to batch repeated clamping and testing.

[0031] After the workpiece is fixed, rotate the lead screw 5 to drive the disc 7 and the adjustment disc 8 on its outer side to adjust the height. The adjustment of the adjustment disc 8 will drive the L-shaped placement plate 21 to move up and down, thereby adjusting the height of the workpiece to the required height.

[0032] Furthermore, rotating the T-shaped frustum 3 allows for changes in the angle of the L-shaped placement plate 21 and the workpiece clamped on it, thus adapting to more usage requirements.

[0033] Furthermore, by rotating the first screw rod 12, in conjunction with the first threaded cylinder 11, the toothed block 13 moves in the first moving groove 10. When the toothed block 13 leaves the tooth groove 14, the adjusting disk 8 can rotate axially at a small angle on the disc 7, thereby tilting the L-shaped placement plate 21 and the workpiece clamped on it to the required tilt angle. After reaching the required tilt angle, the toothed block 13 is then moved into the tooth groove 14 to fix the position of the adjusting disk 8, thereby fixing the tilt angle of the workpiece.

[0034] Preferably, the rotating base 2 is provided with a fixing mechanism 23. The fixing mechanism 23 includes a rectangular platform 231 fixedly disposed on the outside of the rotating base 2. The rectangular platform 231 has a second moving groove 232 inside. The rectangular platform 231 is connected to a second threaded cylinder 233 outside the rectangular platform 231. The second threaded cylinder 233 communicates with the second moving groove 232. The second threaded cylinder 233 is threadedly connected to a second screw rod 234. An arc-shaped block 235 is rotatably installed at the end of the second screw rod 234. The arc-shaped surface of the arc block 235 is adapted to the outer surface of the T-shaped frustum 3. The arc block 235 is located in the second moving groove 232. The contact surface of the arc block 235 is provided with friction texture. With this design, rotating the second screw rod 234 can make the arc block 235 abut against the outer surface of the T-shaped frustum 3, and brake the T-shaped frustum 3 by friction, preventing the T-shaped frustum 3 from deflecting at an angle when subjected to force. In fact, the structure of the fixing mechanism 23 can also be considered according to specific circumstances.

[0035] The preferred design is that the power ends of lead screw 5 and double-ended lead screw 17 with positive and negative threads are equipped with motors. This design enables automated clamping and automated height adjustment. In fact, the rotation power of lead screw 5 and double-ended lead screw 17 can also be selected according to specific circumstances.

[0036] The outer surface of the preferred rotating base 2 and the upper side of the rectangular through-hole 22 are provided with scale lines 24. With this design, the scale lines on the outer surface of the rotating base 2 facilitate the quick determination of the angle, and the scale lines on the upper side of the rectangular through-hole 22 can quickly read the length or width of the clamping position of the clamped part. In fact, the marking method of the scale lines 24 can also be considered according to the specific situation.

[0037] The preferred clamping head 20 is inserted and installed on the clamping strip 19. This design allows for the replacement of clamping heads 20 of different specifications on the clamping strip 19 by direct insertion and removal. In fact, the installation method of the clamping head 20 can also be considered according to specific circumstances.

[0038] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
