Description

Technical Field

[0001] This utility model relates to the field of galvanized steel pipe clamping technology, specifically to a galvanized steel pipe clamping fixture. Background Technology

[0002] Galvanized steel pipes are welded steel pipes with a hot-dip galvanized or electro-galvanized coating on their surface. Galvanizing increases the corrosion resistance of the steel pipe and extends its service life. Galvanized pipes have a wide range of applications. During the processing of galvanized steel pipes, a certain device must be used to generate clamping force to fix the steel pipe, thereby facilitating processing operations.

[0003] For example, Chinese patent application No. 202421962893.3 provides a galvanized steel pipe clamping fixture, including a mounting base and a loading / unloading assembly. Clamping assemblies are fixedly connected to both sides of the upper surface of the mounting base, and a movable assembly is provided above the outer surface of the clamping assembly. This utility model utilizes the cooperation of a horizontal plate, a sliding groove, a sliding rod, a spring, a connecting block, a V-shaped rubber plate, a clamping plate, and a movable assembly. By pushing the movable assembly, the clamping plate moves downward, thereby stretching the spring, facilitating the clamping and fixing of the galvanized steel pipe. The V-shaped positioning groove in the clamping plate and the V-shaped placement in the mounting base adapt to clamping both square and round galvanized steel pipes, solving the problem of current structures being relatively simple and unable to handle different types of galvanized steel pipes with poor clamping performance. This achieves the effect of easy clamping of galvanized steel pipes and simple and convenient operation.

[0004] However, the following problem still exists in this technical solution: the spring elasticity is used to drive the clamping plate to press the galvanized steel pipe, but the elasticity of the spring will gradually decrease over time, and eventually it will be unable to press and fix the galvanized steel pipe. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping fixture for galvanized steel pipes. The clamping mechanism can fix the galvanized steel pipes, which has a longer service life compared to the spring-pressing method. The installation mechanism also allows for the removal and replacement of the rubber pads, thus avoiding affecting the protection effect on the galvanized steel pipes and solving the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a galvanized steel pipe clamping fixture, including a workbench, and a pressing mechanism for pressing and fixing the galvanized steel pipe on the top of the workbench.

[0007] Preferably, the pressing mechanism includes two support frames located on the top of the workbench. Each support frame has a first fixing frame inside and a second fixing frame at the bottom of the first fixing frame. Each first and second fixing frame has a rubber pad inside. Electric push rods are fixed on both sides of the top of the first fixing frame. The top of the electric push rods passes through the support frame and is used to press and fix the galvanized steel pipe.

[0008] Preferably, limiting cylinders are fixed on both sides of the top of the first fixed frame, and the bottom end of the electric push rod can be inserted into the limiting cylinder. The bottom end of the electric push rod and the limiting cylinder are both provided with first threaded holes, and the two connected first threaded holes are connected with the same first bolt for disassembling the first fixed frame.

[0009] Preferably, a first connecting plate is fixedly provided on one side of the second fixed frame, and a second connecting plate is fixedly provided at the bottom of the support frame. Both the first and second connecting plates are provided with second threaded holes, and the two connected second threaded holes are internally threaded with the same second bolt for disassembling the second fixed frame.

[0010] Preferably, both the first and second fixed frames are provided with an installation mechanism for disassembling and installing the rubber pad. The installation mechanism includes two plug-in plates respectively located on both sides of the rubber pad. The first and second fixed frames are provided with plug-in slots on both sides inside. The plug-in plates and the second fixed frame are provided with third threaded holes. The two connected third threaded holes are internally threaded with the same third bolt. The plug-in plates are adapted to the plug-in slots for disassembling and installing the rubber pad.

[0011] Preferably, the bottom of the workbench is provided with a moving mechanism that drives the two support frames to move. The moving mechanism includes a fixed frame located at the bottom of the workbench. A bidirectional threaded rod is movably connected inside the fixed frame via bearings. Both ends of the bidirectional threaded rod are threaded with moving plates. The top of the moving plates passes through the workbench and extends beyond the top of the workbench. The top of the moving plates is fixedly connected to the bottom of the support frames. A motor is fixedly installed at one end of the bidirectional threaded rod to drive the two support frames to move.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. Place both ends of the galvanized steel pipe on top of the two second fixing frames respectively, and then start the electric push rod. The electric push rod drives the first fixing frame to move downward and move the first fixing frame to the top of the galvanized steel pipe. The galvanized steel pipe can be fixed by the pressing mechanism. Compared with the spring pressing method, this utility model has a longer service life.

[0014] 2. With prolonged use, the rubber pad is prone to wear. To remove and replace the rubber pad, turn the third bolt out of the third threaded hole, and then pull the rubber pad to pull the plug plate on one side of the rubber pad out of the plug groove. This will prevent the rubber pad from affecting the protection of the galvanized steel pipe. Attached Figure Description

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

[0028] This utility model provides, for example Figure 1-6 The galvanized steel pipe clamping fixture shown includes a workbench 1, and a pressing mechanism 2 for pressing and fixing the galvanized steel pipe is provided on the top of the workbench 1.

[0029] like Figure 4 , 5 As shown, the pressing mechanism 2 includes two support frames 201 on the top of the workbench 1. Each support frame 201 has a first fixing frame 202 inside and a second fixing frame 203 at the bottom of the first fixing frame 202. Each first fixing frame 202 and the second fixing frame 203 have a rubber pad 204 inside. Electric push rods 205 are fixed on both sides of the top of the first fixing frame 202. The top of the electric push rod 205 passes through the support frame 201.

[0030] like Figure 6 As shown, the bottom of the workbench 1 is provided with a moving mechanism 4 that drives two support frames 201 to move. The moving mechanism 4 includes a fixed frame 401 located at the bottom of the workbench 1. A bidirectional threaded rod 402 is movably connected inside the fixed frame 401 through a bearing. Both ends of the bidirectional threaded rod 402 are threadedly connected to a moving plate 403. The top of the moving plate 403 passes through the workbench 1 and extends out of the top of the workbench 1. The top of the moving plate 403 is fixedly connected to the bottom of the support frame 201. A motor 404 is fixedly installed at one end of the bidirectional threaded rod 402.

[0031] The motor 404 is started, which drives the bidirectional threaded rod 402 to rotate. The rotation of the bidirectional threaded rod 402 drives the moving plate 403 to move. The movement of the moving plate 403 drives the support frame 201 to move. The distance between the two support frames 201 is adjusted according to the galvanized steel pipe. Then, the two ends of the galvanized steel pipe are placed on top of the two second fixed frames 203 respectively. Then, the electric push rod 205 is started, which drives the first fixed frame 202 to move downward, moving the first fixed frame 202 to the top of the galvanized steel pipe. The rubber pads 204 inside the second fixed frame 203 and the first fixed frame 202 can protect the galvanized steel pipe and prevent scratches from forming on the surface of the galvanized steel pipe. The pressing mechanism 2 can fix the galvanized steel pipe. Compared with the spring pressing method, this utility model has a longer service life.

[0032] like Figure 4 , 5As shown, the first fixed frame 202 has a limiting cylinder 206 fixed on both sides of the top. The bottom end of the electric push rod 205 can be inserted into the limiting cylinder 206. The bottom end of the electric push rod 205 and the limiting cylinder 206 are both provided with a first threaded hole 207. The two connected first threaded holes 207 are threaded with the same first bolt 208. The second fixed frame 203 has a first connecting plate 209 fixed on one side. The support frame 201 has a second connecting plate 210 fixed at the bottom. The first connecting plate 209 and the second connecting plate 210 are both provided with a second threaded hole 211. The two connected second threaded holes 211 are threaded with the same second bolt 212.

[0033] Rotate the first bolt 208 to unscrew it from the first threaded hole 207, pull the first fixing frame 202 to remove the limiting cylinder 206 from the electric push rod 205, then rotate the second bolt 212 to unscrew it from the second connecting plate 210, pull the second fixing frame 203 to remove it from the support frame 201. The first fixing frame 202 and the second fixing frame 203 can be replaced according to the shape of the galvanized steel pipe, thus expanding its practicality.

[0034] like Figure 5 As shown, both the first fixed frame 202 and the second fixed frame 203 are provided with an installation mechanism 3 for disassembling and installing the rubber pad 204. The installation mechanism 3 includes two plug-in plates 301 respectively provided on both sides of the rubber pad 204. The first fixed frame 202 and the second fixed frame 203 are provided with plug-in grooves 302 on both sides inside. The plug-in plates 301 and the second fixed frame 203 are provided with third threaded holes 303. The two connected third threaded holes 303 are threaded with the same third bolt 304. The plug-in plates 301 are adapted to the plug-in grooves 302.

[0035] After prolonged use, the rubber pad 204 is prone to wear. To remove and replace the rubber pad 204, rotate the third bolt 304 out of the third threaded hole 303, and then pull the rubber pad 204 to pull the plug plate 301 on one side of the rubber pad 204 out of the plug groove 302. This will prevent the rubber pad 204 from being affected and thus avoid affecting the protection of the galvanized steel pipe.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
