Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy bar processing technology, and in particular to a positioning and clamping device. Background Technology

[0002] Compared to traditional steel, aluminum alloys have a lower density, resulting in lighter weight per unit volume. They also possess high strength and excellent electrical and thermal conductivity, giving them superior performance in harsh environments such as high temperature and high pressure. Currently, many mechanical components in the aerospace industry use aluminum alloys as their primary structural material. However, when cutting aluminum alloy bars, a positioning and clamping device is required to hold the bar in place. Existing positioning and clamping devices struggle to hold aluminum alloy bars of various sizes, leading to limited applicability and practicality.

[0003] In existing patent CN217167564U, a positioning and clamping device for cutting aerospace aluminum alloy bars is disclosed. Through the design of a second threaded screw, a slider, a sliding rod, a third threaded screw, a moving block, and positioning rods, the distance between the two lower positioning rods is adjusted according to the diameter of the bar, allowing the bar to be placed on the two lower positioning rods. Then, a drive motor rotates the third threaded screw, causing the upper positioning rod to move downwards. Thus, the bar is fully positioned and clamped using the three positioning rods. In summary, the adjustment of the distance between the three positioning rods allows the device to fix bars of various diameters, significantly improving the applicability and practicality of the device.

[0004] However, in the existing methods described above, after the bar stock is cut, personnel still need to manually load the bar stock, which is very inconvenient and has low work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a positioning and clamping device that solves the problem in the prior art that after the bar stock is cut, manual loading of the bar stock is still required, which is very inconvenient and has low work efficiency.

[0006] To achieve the above objectives, this utility model employs a positioning and clamping device, comprising a base, a clamping assembly, and a feeding assembly. The clamping assembly is connected to the base and located above it. The feeding assembly includes a placement frame, a feeding frame, a movable plate, a traction rod, a slide rod, a feeding plate, two round shafts, two springs, and a pushing member. The placement frame is fixedly connected to the base and located above it. The feeding frame is connected to the placement frame and located above it. The slide rod is fixedly connected to the placement frame and movably passes through it. The feeding plate is fixedly connected to one end of the slide rod. The movable plate is fixedly connected to the other end of the slide rod. The traction rod is fixedly connected to the movable plate and located on the outer wall of the movable plate. Both round shafts are fixedly connected to the placement frame and located on the outer wall of the placement frame. Both ends of each spring are fixedly connected to the traction rod and the corresponding round shaft, respectively. The pushing member is disposed on the feeding frame.

[0007] The pushing component includes a first telescopic rod and a push plate. The first telescopic rod is fixedly connected to the base and located above the base. The push plate is fixedly connected to the output end of the first telescopic rod and located inside the feeding frame.

[0008] The feeding assembly includes a squeezed sponge pad, which is fixedly connected to the feeding plate and located on the outer side wall of the feeding plate.

[0009] The clamping assembly includes two second telescopic rods, two clamps, and a U-shaped frame. The U-shaped frame is fixedly connected to the base and located on the outer side wall of the base. The two clamps are symmetrically arranged inside the U-shaped frame. The two ends of each second telescopic rod are fixedly connected to the U-shaped frame and the corresponding clamp, respectively.

[0010] The clamping assembly further includes two rubber pads, which are fixedly connected to the corresponding clamps and are located on the inner sidewalls of the clamps.

[0011] This utility model discloses a positioning and clamping device. When processing aluminum alloy bars, multiple bars are first stacked in a placement frame. The feeding plate, when compressed, causes the sliding rod to slide outwards on the placement frame. The movable plate gradually moves away from the placement frame, and the traction rod behind the movable plate stretches the return spring. After the bars are stacked (until the last bar is in the feeding frame), the pushing component is activated. The pushing component moves the bars within the feeding frame to the clamping assembly, which then clamps and fixes the bars. Simultaneously, when a bar leaves the placement frame, the return spring causes the feeding plate to continue placing the next bar in the feeding frame, thus achieving intermittent bar feeding. Using this method, automatic bar feeding and fixing are achieved, greatly reducing manual operation and improving work efficiency. Attached Figure Description

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1-4 This utility model provides a positioning and clamping device, comprising a base 101, a clamping assembly, and a feeding assembly. The clamping assembly is connected to the base 101 and located above the base 101. The feeding assembly includes a placement frame 102, a feeding frame 103, a movable plate 104, a traction rod 105, a slide rod 106, a feeding plate 107, two round shafts 108, two springs 109, and a pushing component. The placement frame 102 is fixedly connected to the base 101 and located above the base 101. The feeding frame 103 is connected to the placement frame 102 and located above the base 101. The slide rod 106 is connected to... The placement frame 102 is fixedly connected and movably passes through the placement frame 102. The feeding plate 107 is fixedly connected to one end of the slide rod 106. The movable plate 104 is fixedly connected to the other end of the slide rod 106. The traction rod 105 is fixedly connected to the movable plate 104 and is located on the outer side wall of the movable plate 104. Both of the two round shafts 108 are fixedly connected to the placement frame 102 and are located on the outer side wall of the placement frame 102. Both ends of each spring 109 are fixedly connected to the traction rod 105 and the corresponding round shaft 108, respectively. The pushing member is disposed on the feeding frame 103.

[0020] In this embodiment, when processing aluminum alloy bars, multiple bars are first stacked in the placement frame 102. When the feeding plate 107 is compressed, it causes the sliding rod 106 to slide outward on the placement frame 102. The movable plate 104 gradually moves away from the placement frame 102. The traction rod 105 on the rear side of the movable plate 104 stretches the return spring 109. After the bars are stacked (until the last bar is in the feeding frame 103), the pusher is activated. The pusher moves the bar in the feeding frame 103 to the clamping assembly, which then clamps and fixes the bar. At the same time, when a bar leaves the placement frame 102, the return spring 109 causes the feeding plate 107 to continue to place the next bar in the feeding frame 103, thus achieving intermittent bar feeding. By using the above method, automatic feeding and fixing of bars are achieved, greatly reducing manual operation and improving work efficiency.

[0021] Furthermore, the pushing member includes a first telescopic rod 110 and a push plate 111. The first telescopic rod 110 is fixedly connected to the base 101 and is located above the base 101. The push plate 111 is fixedly connected to the output end of the first telescopic rod 110 and is located inside the feeding frame 103.

[0022] In this embodiment, when the bar stock is pushed toward the clamping assembly, the first telescopic rod 110 on the base 101 is activated. The first telescopic rod 110 drives the push plate 111 to move within the feeding frame 103, and then the push plate 111 feeds the bar stock into the clamping assembly for fixation.

[0023] Furthermore, the feeding assembly includes a squeezed sponge pad 112, which is fixedly connected to the feeding plate 107 and located on the outer side wall of the feeding plate 107.

[0024] In this embodiment, by providing the compression sponge pad 112 on the outer side wall of the feeding plate 107, the compression sponge pad 112 can increase the friction between the feeding plate 107 and the bar stock, thereby facilitating the pushing of the bar stock.

[0025] Furthermore, the clamping assembly includes two second telescopic rods 113, two clamps 114, and a U-shaped frame 115. The U-shaped frame 115 is fixedly connected to the base 101 and located on the outer side wall of the base 101. The two clamps 114 are symmetrically arranged inside the U-shaped frame 115. The two ends of each second telescopic rod 113 are fixedly connected to the U-shaped frame 115 and the corresponding clamp 114, respectively.

[0026] In this embodiment, when clamping and fixing the bar stock, the bar stock is first pushed into the space between the two clamps 114 by the push plate 111, and then the two second telescopic rods 113 in the U-shaped frame 115 are activated, and the two clamps 114 are driven to move closer to the outer wall of the bar stock, and then the bar stock is clamped and fixed.

[0027] Furthermore, the clamping assembly also includes two rubber pads 116, which are fixedly connected to the corresponding clamps 114 and are located on the inner sidewalls of the clamps 114 respectively.

[0028] In this embodiment, by providing the rubber pad 116 on the inner sidewall of the sleeve 114, the rubber pad 116 can increase the friction between the sleeve 114 and the bar stock, thereby making the bar stock more securely fixed.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
