Description

Technical Field

[0001] This utility model relates to the field of metal powder feeding technology, specifically a positioning fixture for metal powder feeding. Background Technology

[0002] In modern manufacturing, metal powders, with their superior material properties, are widely used in high-end manufacturing fields such as 3D printing, powder metallurgy, and precision casting. Whether it's high-temperature alloy components required in the aerospace industry, precision gear blanks in the automotive industry, or personalized implants in the medical industry, all require high-quality metal powders as raw materials and are produced through specific molding processes.

[0003] In the actual operation of metal powder feeding process, the stable connection between the feeding pipe and the feeding hopper is crucial for ensuring accurate powder delivery. Currently, the industry commonly uses a connecting flange and connecting bolts to connect the two. While this method can achieve structural fastening to a certain extent, it reveals significant operational inconveniences in actual production applications. Each time an installation or disassembly operation is performed, the operator must align the flange holes one by one and then manually or with tools tighten / untighten multiple sets of connecting bolts. This not only involves cumbersome operation steps and high requirements for hole alignment accuracy, but also significantly extends the process interval time due to the lengthy disassembly and assembly process, severely restricting production continuity. Therefore, a positioning fixture for metal powder feeding is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a positioning fixture for feeding metal powder, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a positioning clamp for feeding metal powder, comprising: a fixing frame, wherein a receiving hopper for receiving metal powder is installed on the outside of the fixing frame;

[0006] A feeding pipe is used to transport metal powder, and the feeding pipe is connected to the discharge end of the receiving hopper;

[0007] A clamping assembly for clamping and positioning the feed pipe and the receiving hopper.

[0008] Furthermore, the clamping assembly includes a gantry-shaped mounting frame, a mounting platform is fixedly connected to the rear outer surface of the gantry-shaped mounting frame, a side plate is fixedly connected to the top outer surface of the mounting platform, two symmetrically arranged cylinders are mounted on the rear outer surface of the side plate, a Z-shaped mounting plate is fixedly mounted on the output end of the cylinders, an L-shaped connecting plate is fixedly mounted on the outer surface of the other end of the Z-shaped mounting plate, and a mounting plate is vertically mounted on the other end of the L-shaped connecting plate. Both mounting plates have arc-shaped clamping plates installed on their outer surfaces for clamping and positioning the connection between the feed tube and the receiving hopper.

[0009] Furthermore, L-shaped support plates for fixing the gantry-shaped mounting bracket are installed on the outer surfaces of both the left and right sides of the fixing frame, and the two ends of the gantry-shaped mounting bracket are respectively installed on the two L-shaped support plates.

[0010] Furthermore, a sealing gasket is provided at the connection between the feeding pipe and the receiving hopper, and a receiving groove for accommodating the sealing gasket is provided inside the arc-shaped clamp.

[0011] Furthermore, a slide rail is fixedly connected to the rear outer surface of the side plate, and a slider is fixedly connected to the rear outer surface of the L-shaped connecting plate, with the slider movably sleeved on the outer surface of the slide rail.

[0012] Furthermore, two grooves are formed on the outer surface of the side plate, and the two Z-shaped mounting plates are slidably connected to the inside of the two grooves respectively.

[0013] Furthermore, the arc-shaped clamping plate and the fixing plate are connected by bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention uses a clamping assembly to clamp and position the connection between the feeding pipe and the receiving hopper. By retracting the cylinder, two arc-shaped clamps are driven to clamp and position the connection between the feeding pipe and the receiving hopper. By extending the telescopic end of the cylinder, the arc-shaped dummy plate is disengaged from the connection between the feeding pipe and the receiving hopper, thereby enabling the feeding pipe and the receiving hopper to be quickly separated, improving the efficiency of disassembly and installation.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to the following: Figures 1-4 This utility model provides a technical solution: a positioning fixture for feeding metal powder, comprising: a fixing frame 100, a feeding pipe 200, and a clamping assembly 300. A receiving hopper 101 for receiving metal powder is installed on the outside of the fixing frame 100. The feeding pipe 200 is used to transport metal powder and is connected to the discharge end of the receiving hopper 101. The clamping assembly 300 is used to clamp and position the feeding pipe 200 and the receiving hopper 101. Specifically, the clamping assembly 300 positions the connection between the feeding pipe 200 and the receiving hopper 101. The other end of the feeding pipe 200 is connected to a device for transporting metal powder. The metal powder is transported through the feeding pipe 200 and enters the receiving hopper 101 for feeding.

[0023] Furthermore, the clamping assembly 300 includes a gantry-shaped mounting bracket 500. A mounting platform 301 is fixedly connected to the rear outer surface of the gantry-shaped mounting bracket 500. A side plate 309 is fixedly connected to the top outer surface of the mounting platform 301. Two symmetrically arranged cylinders 302 are mounted on the rear outer surface of the side plate 309. A Z-shaped mounting plate 303 is fixedly mounted at the output end of the cylinders 302. An L-shaped connecting plate 304 is fixedly mounted on the outer surface of the other end of the Z-shaped mounting plate 303. A mounting plate is vertically mounted on the other end of the L-shaped connecting plate 304. Both mounting plates have arc-shaped clamping plates 306 mounted on their outer surfaces for clamping and positioning the connection between the feed pipe 200 and the receiving hopper 101. Specifically, the feed pipe 200 is aligned with the feed end of the receiving hopper 101, and the sealing is... The pad is placed at the connection between the feeding pipe 200 and the receiving hopper 101. The clamping assembly 300 operates, and the cylinder 302 operates, causing the cylinder 302 to retract. The output end of the cylinder 302 drives the Z-shaped mounting plate 303, which in turn causes the L-shaped connecting plate 304 to drive the fixing plate 305 to retract and move. The fixing plate 305 drives the arc-shaped clamping plate 306 to clamp and fix the feeding pipe 200 and the receiving hopper 101, increasing the stability of the feeding pipe 200 and the receiving hopper 101. When disassembly is required, the cylinder 302 operates, and the output end of the cylinder 302 extends, causing the arc-shaped clamping plate 306 to detach from the feeding pipe 200 and the receiving hopper 101, thereby enabling the feeding pipe 200 and the receiving hopper 101 to be quickly separated, improving the efficiency of disassembly and installation.

[0024] Furthermore, L-shaped support plates 400 for fixing the portal frame 500 are installed on the outer surfaces of both the left and right sides of the fixing frame 100. The two ends of the portal frame 500 are respectively installed on the two L-shaped support plates 400. Specifically, the device is fixed on the fixing frame 100 by installing the portal frame 500 on the L-shaped support plates 400, and the device is used to clamp and position the feed pipe 200 and the receiving hopper 101.

[0025] Furthermore, a sealing gasket 308 is provided at the connection between the feeding pipe 200 and the receiving hopper 101, and the inside of the arc-shaped clamping plate 306 is provided with a receiving groove 307 for accommodating the sealing gasket 308. Specifically, the sealing gasket 308 increases the sealing between the feeding pipe 200 and the receiving hopper 101, and the receiving groove 307 allows the arc-shaped clamping plate 306 to accommodate the sealing gasket 308 when clamping the feeding pipe 200 and the receiving hopper 101.

[0026] Furthermore, a slide rail 311 is fixedly connected to the rear outer surface of the side plate 309, and a slider 312 is fixedly connected to the rear outer surface of the L-shaped connecting plate 304. The slider 312 is movably sleeved on the outer surface of the slide rail 311. Specifically, when the cylinder 302 is working, it drives the Z-shaped mounting plate 303 to move, so that the Z-shaped mounting plate 303 drives the slider 312 to slide on the surface of the slide rail 311, so that the slider 312 moves stably.

[0027] Furthermore, two grooves 310 are provided on the outer surface of the side plate 309, and two Z-shaped mounting plates 303 are slidably connected to the interior of the two grooves 310 respectively. Specifically, when the cylinder 302 is working, it drives the Z-shaped mounting plate 303 to move, so that the Z-shaped mounting plate 303 slides inside the groove 310, and the groove 310 provides a channel for the movement of the Z-shaped mounting plate 303.

[0028] Furthermore, the arc-shaped clamping plate 306 and the fixed plate 305 are connected by bolts. Specifically, the arc-shaped clamping plate 306 and the fixed plate 305 are connected by bolts. When connecting the feed pipe 200 of different sizes to the receiving hopper 101, the arc-shaped clamping plate 306 is disassembled and arc-shaped clamping plates 306 of different curvatures are installed.

[0029] Working principle: In use, the feeding pipe 200 is aligned with the feeding end of the receiving hopper 101, and a sealing gasket is placed at the connection between the feeding pipe 200 and the receiving hopper 101. The clamping assembly 300 operates, and the cylinder 302 retracts. The output end of the cylinder 302 drives the Z-shaped mounting plate 303, which in turn drives the L-shaped connecting plate 304 to retract and move the fixing plate 305. The fixing plate 305 then drives the arc-shaped clamping plate 306 to clamp and fix the feeding pipe 200 and the receiving hopper 101, increasing the stability of the feeding pipe 200 and the receiving hopper 101. When disassembly is required, the output end of the cylinder 302 extends, causing the arc-shaped clamping plate 306 to detach from the feeding pipe 200 and the receiving hopper 101, thereby enabling the feeding pipe 200 and the receiving hopper 101 to be quickly separated, improving the efficiency of disassembly and installation.
