[0001] This utility model relates to the field of clamps, and more particularly to a clamp. Background Technology

[0002] In modern industrial production, especially in the field of dual-machine arc welding, the requirements for production efficiency and welding quality are increasingly demanding. Dual-machine arc welding workbenches require clamps to hold the workpieces during welding to ensure welding accuracy and stability. However, traditional clamps on dual-machine arc welding workbenches often have many limitations.

[0003] Traditional fixtures are typically designed and installed for specific types or sizes of workpieces, with fixed structures and a lack of flexibility. When the production line needs to weld workpieces of different shapes, sizes, or materials, the existing fixtures cannot quickly adapt to the new requirements. This results in a significant amount of time and manpower being spent disassembling old fixtures and installing new ones when switching production tasks, severely impacting production efficiency and increasing production costs. Moreover, frequent fixture changes, if not convenient and efficient, can also cause wear or damage to the workbench and related equipment, further affecting the equipment's lifespan and performance stability.

[0004] In view of the above, there is an urgent need for a fixture that can be quickly changed on a dual-machine arc welding workbench to ensure good applicability when facing diverse welding tasks, thereby improving the overall production efficiency and quality of dual-machine arc welding.

When switching between welding tasks for different workpieces, no complex tools or lengthy operations are required; disassembly is simply achieved by rotating the nuts sequentially to release their locks. This significantly reduces the time needed for fixture replacement, thereby improving the overall production efficiency of the dual-machine arc welding workbench. The quick-change design also makes the replacement operation simpler and gentler, reducing damage to the equipment caused by frequent fixture changes.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution that allows for quick replacement of fixtures on a dual-machine arc welding workbench to ensure applicability.

[0009] Preferably, the connecting bolt is engaged at one end of the inner groove and extends to its outside, the square washer is sleeved on the extended connecting bolt, the square washer contacts the outer periphery of the inner groove and is connected to the connecting bolt by a nut in a threaded manner.

[0010] Preferably, a guide assembly is provided between the connector and the fixing member. The guide assembly includes a first tooth block and a second tooth block. The first tooth block is bolted to the upper and lower ends of the connector, and the second tooth block is bolted to the upper and lower ends of the fixing member. The first tooth block and the second tooth block match each other and mesh to achieve the guiding function.

[0011] Preferably, the connector has a first mounting groove at both the upper and lower ends, and a first toothed block is inserted into the corresponding first mounting groove.

[0012] Preferably, the fixing member has a second mounting groove at both the upper and lower ends, and the second tooth block is inserted into the corresponding second mounting groove.

[0013] Preferably, a guide groove is provided on one side of the fixing member, and a guide block is connected to the front end of the connector, the guide block being inserted into the guide groove opening.

Example

[0035] Please see Figure 1-7A fixture includes a working position 2 set inside a fixture bracket 1. Symmetrical motor frames 3 are provided on both the front and rear ends of the working position 2. The motor frames 3 are equipped with connecting plates 301. A welding platform 4 is provided between the two motor frames 3. The motor frames 3 and the welding platform 4 are connected by a fixing member 5. One end of the fixing member 5 is connected to the welding platform 4, and the other end of the fixing member 5 has an inner groove 501. A connecting member 303 is connected to the connecting plate 301 by bolts. The upper and lower ends of the connecting member 303 are connected to connecting bolts 304 by a rotating shaft. One end of the connecting bolt 304 is locked inside the inner groove 501 and is locked to the fixing member 5 by a square washer 305 and a nut 306 to maintain stability.

[0036] The fixture of this application is mainly composed of fixture bracket 1, working position 2, motor frame 3, connecting plate 301, welding platform 4, fastener 5, inner groove 501, connector 303, connecting bolt 304 and square washer 305, etc. The following is a detailed description of its structure and working principle.

[0037] I. Fixture Assembly

[0038] Install the working position 2 into the fixture bracket 1 using bearings, ensuring that the working position 2 can rotate freely. Install the motor frame 3 onto the front and rear ends of the working position 2 using bolts. First, position the motor frame 3 on the working position 2, and then use high-strength bolts to tighten the motor frame 3, ensuring that the motor frame 3 is firmly installed and symmetrically parallel on both sides. The motor frame 3 contains a motor; install the motor into the motor frame 3 and fix the motor to the motor frame 3 using bolts. Connect the motor shaft to the connecting plate 301 using a key. Install a flat key in the keyway of the connecting plate 301, and then install the connecting plate 301 onto the motor shaft and fix it, ensuring the concentricity of the connecting plate 301 and the motor shaft.

[0039] The connector 303 is bolted to the connecting plate 301. Then, the inner grooves 501 at the upper and lower ends of the fixing member 5 facing the connector 303 are aligned with the connecting bolts 304 on the front face of the connector 303. The connecting bolts 304 are rotated to engage within the inner grooves 501 and extend to the outside. A square washer 305 is fitted onto the extended end of the connecting bolt 304, so that the square washer 305 fits against the outer periphery of the opening of the inner groove 501 and the outer wall of the fixing member 5. Finally, the fastener is secured with a nut 306.

[0040] The first toothed block 601 is bolted into the first mounting groove 6 at the upper and lower ends of the connector 303, and the second toothed block 602 is bolted into the second mounting groove 603 at the upper and lower ends of the fixing member 5. When installing the fixing member 5 and the connector 303, ensure accurate meshing of the first toothed block 601 and the second toothed block 602, achieving rapid position correction through the guiding action of the toothed blocks. A guide block 307 is installed in the middle of the front end of the connector 303, matching the guide groove 502 on the side of the fixing member 5. When the fixing member 5 and the connector 303 are connected, the guide block 307 can be driven into the guide groove 502 for positioning during assembly.

[0041] Positioning grooves 402 are machined at the front corners of the connecting plates 401 on both sides of the welding platform 4. The top plate 7 is installed on the top of the fixing member 5 facing the connecting plate 401. A positioning block 701 is installed at the bottom of the top plate 7, and a magnetic suction plate 702 is glued to the inner end face of the positioning block 701. During assembly, the positioning block 701 is inserted into the front opening of the positioning groove 402. At the same time, the limiting member 703 at the front end of the top plate 7 plays a limiting role. The magnetic attraction between the magnetic suction plate 702 and the inner end face of the positioning groove 402 ensures the stability of the connection.

[0042] II. Working Principle

[0043] Connection between fastener 5 and connector 303

[0044] One end of the fixing member 5 is fastened to the side of the welding platform 4 with bolts. This bolted connection provides sufficient strength to ensure that the fixing member 5 and the welding platform 4 will not separate during welding. The other end of the fixing member 5 is connected to the connector 303. The connector 303 is bolted onto the connecting plate 301. The rotational power of the connecting plate 301 is transmitted to the fixing member 5 through the connector 303, thereby driving the welding platform 4 to rotate. The fixing member 5 has inner grooves 501 on the upper and lower ends facing the connector 303. The front end face of the connector 303 is rotatably connected to the connecting bolts 304 via a pivot. During connection, the connecting bolts 304 are rotated to be on the same horizontal line as the inner grooves 501, and then the connecting bolts 304 are inserted into the inner grooves 501 and extended to the outside.

[0045] Fastening principle

[0046] A square washer 305 is fitted onto the outer end of the connecting bolt 304. The function of the square washer 305 is to increase the contact area between the nut 306 and the fixing part 5, disperse the pressure generated when the nut 306 is tightened, and prevent local deformation of the fixing part 5. The square washer 305 fits against the outer periphery of the opening of the inner groove 501 and the outer wall of the fixing part 5. Then, the square washer 305 is tightened onto the fixing part 5 by rotating the nut 306. The nut 306 engages with the connecting bolt 304 through its threads. When tightening the nut 306, the nut 306 moves axially along the thread of the connecting bolt 304, pressing the square washer 305 tightly onto the fixing part 5, thus achieving a quick connection between the welding platform 4 and the motor frame 3. When disassembly is required, simply rotate the nut 306 in the opposite direction to remove the nut 306 and the square washer 305 in sequence, and then remove the connecting bolt 304 from the inner groove 501, thus achieving quick disassembly.

[0047] Guidance and Positioning Principles

[0048] The fixing member 5 has a second toothed block 602 at its upper and lower ends facing the connector 303, and the connector 303 has a first toothed block 601 at its upper and lower ends. The toothed structures of the first toothed block 601 and the second toothed block 602 are matched.

[0049] When installing the fixing component 5 and the connecting component 303, the first toothed block 601 and the second toothed block 602 begin to mesh when they are close together. Because the tooth shape of the toothed block has a guiding function, during meshing, the toothed block guides the fixing component 5 and the connecting component 303 to move accurately relative to each other, quickly correcting any positional deviations. This guiding function ensures that the fixing component 5 and the connecting component 303 are accurately connected each time they are installed, guaranteeing the accuracy and stability of the connection between the welding platform 4 and the motor frame 3, thereby ensuring the positional accuracy of the workpiece during welding and playing a crucial role in improving welding quality. Working principle of the positioning assembly top plate 7, positioning block 701, magnetic suction plate 702, and limiting component 703.

[0050] Positioning and Stability Principles

[0051] The welding platform 4 is symmetrically equipped with connecting plates 401 on both sides, and a positioning groove 402 is provided at the corner of the front end of the connecting plate 401. The top plate 7 is installed on the top of the fixing member 5 facing the connecting plate 401, and a positioning block 701 is installed at the bottom of the top plate 7.

[0052] During assembly, as the fastener 5 approaches the welding platform 4, the positioning block 701 first contacts the positioning groove 402. The positioning block 701 inserts into the front opening of the positioning groove 402, achieving initial positioning of the fastener 5 and the welding platform 4. This initial positioning helps operators quickly align the fastener 5 and the welding platform 4 during installation, improving installation efficiency.

[0053] A limiting component 703 is installed at the front end of the top plate 7. When the positioning block 701 is inserted into the positioning groove 402, the limiting component 703 will restrict the further movement of the top plate 7, ensuring that the positioning block 701 remains in the correct position within the positioning groove 402. The slotted design at the bottom of the limiting component 703 facilitates hand operation by the operator, making installation and disassembly convenient.

[0054] A magnetic suction plate 702, made of magnetic material, is glued to the inner end face of the positioning block 701. When the positioning block 701 is inserted into the positioning groove 402, the magnetic suction plate 702 and the inner end face of the positioning groove 402 are magnetically attracted to each other. This magnetic attraction further ensures the stability of the connection between the fixing component 5 and the welding platform 4, preventing slight displacement between the fixing component 5 and the welding platform 4 due to vibration or other reasons during the welding process, thus ensuring welding accuracy.

[0055] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
