Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a hydraulic support connecting rod fixture. Background Art

[0002] Connecting rod robots are used for welding hydraulic support components, reducing manual welding workload and preventing occupational hazards such as welding radiation. However, the factory-installed worktable for connecting rod robots has a limited range of dimensions, which limits the clamping capacity of the ultra-short connecting rods used in some small hydraulic supports. The existing connecting rod welding robot's worktable cannot hold these connecting rods, making them unsuitable for welding. This welding work must be performed manually, significantly increasing the workload and labor costs.

[0003] The connecting rods in small hydraulic supports are small in size, with a length usually ranging from 650-1000mm. The clamping size range of the workbench on the original connecting rod robot is usually 1100-3000mm. The original workbench cannot meet the needs of clamping such small-sized connecting rods, resulting in the inability to use robots to weld batches of small-sized connecting rods, increasing the workload of manual welding and increasing production costs.

[0004] Therefore, there is an urgent need for a hydraulic support connecting rod fixture that can cooperate with the workbench of the connecting rod robot equipment and clamp small-sized connecting rods to realize machine welding and improve welding efficiency. Utility Model Content

DETAILED DESCRIPTION

[0038] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0039] Aiming at the problem that the workbench of the existing connecting rod robot cannot fix the small-sized hydraulic support connecting rod 7 (ultra-short hole pitch connecting rod), the fundamental reason why the robot cannot perform ultra-short connecting rod welding is analyzed. The utility model provides a hydraulic support connecting rod tooling fixture, which can be installed on the workbench of the connecting rod robot equipment to clamp the small-sized hydraulic support connecting rod 7, realize machine welding, and improve welding efficiency.

[0040] To better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0041] See attached Figure 1-8 As shown, the present invention provides a hydraulic support connecting rod fixture for use with a connecting rod robot for welding hydraulic support connecting rods 7. The fixture is secured to the robot's rotating tire via a hoisting mechanism. The fixture comprises a fixture wall for positioning and connecting the robot's rotating tire, a clamping member 4 for clamping the hydraulic support connecting rod 7, and a screw assembly for engaging the clamping member 4. The screw assembly includes a first screw 61 and a second screw 62, each fixedly connected to the first fixture wall 33 and the second fixture wall 34, respectively. The distance between the first screw 61 and the second screw 62 is adjustable. A fixing device 1 for connecting to the robot's rotating tire is provided on the outer surface of the fixture wall. The fixing device 1 is secured to the robot's rotating tire via a clamping member 4. The clamping members 4 are arranged in pairs and rotatably mounted on the screw 6. The distance between the clamping members 4 is adjustable. The small-sized hydraulic support connecting rod 7 is sleeved onto the first and second screws 61 and 62 through through-holes formed at the ends and is tightly clamped by the clamping member 4.

[0042] By setting up a tooling wall, the connecting rod tooling fixture can be installed on the robot's rotating tire; by combining the tooling wall with the screw assembly, the spacing of the screws can be adjusted, so that the connecting rod tooling fixture can adapt to small-sized hydraulic support connecting rods 7 of different lengths; by setting up a clamping piece 4 with adjustable spacing, the small-sized hydraulic support connecting rod 7 can be clamped and fixed on the robot's rotating tire by the connecting rod tooling fixture, so that the connecting rod robot can perform welding operations on the small-sized hydraulic support connecting rod 7.

[0043] The tooling wall is clipped and fixed to the robot's rotating tire. The tooling wall includes a first tooling wall 33 and a second tooling wall 34, which are arranged opposite each other at the ends of the screw assembly. A fixing device 1 is provided on the side of the tooling wall. The fixing device 1 protrudes from the side of the tooling wall and is cylindrical. The outer edge of the end of the fixing device 1 is provided with an inclined surface. The installation of the fixing device 1 enables the connecting rod fixture to be used in conjunction with the connecting rod robot's rotating tire to achieve mechanical welding of the connecting rod 7 of a small-sized hydraulic support. The tooling wall in this embodiment is 1350 mm long, and the fixing device 1 is 90 mm long and 100 mm in diameter.

[0044] The clamping member 4 is truncated cone-shaped, with a central through-hole for the screw 6. The inner wall of the through-hole is threaded, and the clamping member 4 is threadedly connected to the screw 6 via the threads on the inner wall of the through-hole. The position of the clamping member 4 can be adjusted by rotating the clamping member 4, moving it along the screw 6. In this embodiment, the diameter of one circular side of the clamping member 4 is 125 mm, the diameter of the other circular side is 310 mm, and the diameter of the central through-hole is 60 mm.

[0045] The invention also includes a fastener 2 for securing the screw assembly to the tooling wall. The screw assembly passes through the tooling wall and is removably fixedly connected to the fastener 2. A connecting groove 21 for connecting the screw assembly is provided in the middle of the fastener 2. The inner side wall of the connecting groove 21 is provided with threads. The outer wall of the screw 6 is provided with threads. The end of the screw assembly is inserted into the connecting groove 21 and is threadedly connected to the connecting groove 21. The combination of the fastener 2, the screw assembly, and the tooling wall enables the connecting rod fixture to accommodate small-sized hydraulic support connecting rods 7 of different lengths, providing a wider range of adaptability. The length of the screw 6 in this embodiment is 1900 mm, the diameter of the screw 6 is 60 mm, and the diameter of the connecting groove 21 is 60 mm.

[0046] The end of the small-sized hydraulic support connecting rod 7 has a through hole for connecting other structural parts. The screw assembly passes through the through hole and then rotates and adjusts the clamping member 4 to clamp and fix the small-sized hydraulic support connecting rod 7.

[0047] Example 1:

[0048] The tooling wall is a plate-like member. The first tooling wall 33 defines a slot 32 through which one end of the lead screw assembly passes. The first and second lead screws 61, 62 pass through the slot 32 and are threadedly connected to the fastener 2. The fastener 2 is detachable, and the spacing between the first and second lead screws 61, 62 can be adjusted by adjusting the position of the slot 32 where the first and second lead screws 61, 62 connect.

[0049] The slide groove 32 is a straight through groove, and an arc-shaped side wall is provided at the end of the straight through groove. By providing the through groove with an arc-shaped end, the shape of the slide groove 32 matches the shape of the lead screw 6.

[0050] Example 2:

[0051] The tooling wall is a plate-like member with a slot 32 for one end of a first lead screw 61 to pass through, and a mounting hole 31 for a second lead screw 62 to pass through. The first lead screw 61 passes through the slot 32 and is fixedly connected to the tooling wall via a fastener 2. The second lead screw 62 passes through the mounting hole 31 and is fixedly connected to the tooling wall via a fastener 2.

[0052] A chute 32 is provided at one end of the tooling wall. This is a linear through-channel with curved sidewalls at its ends, aligning the shape of the chute 32 with that of the lead screw 6. In this embodiment, the linear through-channel is 310 mm long, 62 mm wide, and 62 mm in diameter. The spacing between adjacent lead screws can be adjusted by securing the lead screws in different positions within the chute 32.

[0053] Multiple mounting holes 31 are evenly spaced and arranged in sequence on the end of the tooling wall away from the slide slot 32. The mounting holes 31 are circular through-holes, and in this embodiment, each mounting hole 31 has a diameter of 62 mm. By connecting screws to mounting holes 31 at different positions, the spacing between two adjacent screws can be adjusted.

[0054] By adjusting the distance between the first screw 61 and the second screw 62 , the small-sized hydraulic support connecting rods 7 of different lengths can be adapted, making the connecting rod fixture more adaptable.

[0055] Example 3:

[0056] Both ends of the screw assembly are provided with clamping parts 4, so that the connecting rod fixture can clamp two small-sized hydraulic support connecting rods 7 at the same time.

[0057] The clamping members 4 are arranged in pairs, with each clamping member 4 provided on both sides of the hydraulic support connecting rod 7. Alternatively, a clamping member 4 can be provided on the side of the hydraulic support connecting rod 7 facing away from the tooling wall, so that the hydraulic support connecting rod 7 is tightly clamped between the clamping member 4 and the tooling wall. Both of these solutions can simultaneously clamp two small-sized hydraulic support connecting rods 7.

[0058] Example 4:

[0059] The connecting rod fixture also includes a sling 5 mounted on the lead screw 6. The middle of the sling 5 is provided with a connection hole for passing the lead screw 6. The end of the sling 5 is provided with a lifting ring 51, which is used to connect to a crane, and the connecting rod fixture is lifted to the robot rotating tire by the crane.

[0060] When using the hydraulic support connecting rod fixture provided by the present invention, the lead screw assembly is first passed through the through-holes at both ends of the small-sized hydraulic support connecting rod 7. The fixture wall is then installed, and the ends of the lead screw assembly are respectively connected to the mounting holes 31 and / or the slide grooves 32 at appropriate locations on the fixture wall. The lead screw assembly is then secured to the fixture wall using the fasteners 2. The clamping members 4 are then adjusted to clamp and secure the small-sized hydraulic support connecting rod 7. Finally, a crane is connected via the lifting ring 51 of the lifting fixture 5. The connecting rod fixture, holding the small-sized hydraulic support connecting rod 7, is then hoisted onto the robot's rotating wheel and secured, thereby achieving mechanical welding of the small-sized hydraulic support connecting rod 7.

[0061] The utility model provides a hydraulic support connecting rod fixture. By arranging a fixture wall, the connecting rod fixture can be installed on a rotating tire of a robot.

[0062] By combining the lead screw assembly with the fixture wall, the spacing between the lead screws can be adjusted, so that the connecting rod fixture can adapt to small-sized hydraulic support connecting rods 7 of different lengths, and has wider adaptability.

[0063] By setting a clamping piece 4 with adjustable spacing to clamp the small-sized hydraulic support connecting rod 7, the small-sized hydraulic support connecting rod 7 can be fixed on the connecting rod fixture, and then fixed on the robot rotating tire through the connecting rod fixture, so that the connecting rod robot can weld the small-sized hydraulic support connecting rod 7, thereby realizing mechanical welding of the small-sized hydraulic support connecting rod 7.
