Description

Technical Field

[0001] This utility model belongs to the technical field of welding fixtures for track roller blanks, and particularly relates to a welding fixture for track roller blanks. Background Technology

[0002] Track rollers are an important component of the four wheels and one track of tracked engineering machinery chassis. Track roller blanks are the initial materials for manufacturing track rollers, and are usually semi-finished products made through processes such as forging or casting. In summary, the existing technology has the following problems: Track roller blanks need to be welded. Welding can firmly connect different components together to form an integral structure, improving the load-bearing capacity and impact resistance of the track roller. During welding, welding brackets are needed to position the track roller. Usually, the position of the clamping parts of the welding bracket is adjusted by bolts. The bolts are prone to loosening when subjected to external pressure and impact. Moreover, the installation and removal of bolts require constant adjustment using special tools, which is time-consuming, labor-intensive and inconvenient. However, the existing clamping fixtures used for welding track roller blanks do not have components that provide more stable and convenient positioning of the track roller. Therefore, a welding fixture for track roller blanks is proposed to solve the above problems. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a welding fixture for support roller blanks. This fixture offers the advantage of providing more stable and convenient positioning for the support rollers during welding. It solves the problem that existing support roller blanks require welding, which securely connects different components into a single structure, improving the load-bearing capacity and impact resistance of the support roller. However, welding requires a welding bracket to position the support roller, typically using bolts to adjust the position of the clamping parts. These bolts are prone to loosening under external pressure and impact, and their installation and removal require constant adjustment using specialized tools, which is time-consuming, labor-intensive, and inconvenient. Furthermore, existing support roller blank welding fixtures lack components for more stable and convenient positioning of the support rollers.

[0004] This utility model is implemented as follows: a welding fixture for a support roller blank includes a welding base and two welding supports. The bottom of the welding supports is fixedly connected to the top of the welding base. A limiting frame is movably connected to one side of each of the two welding supports. A limiting shell is movably connected to the inner cavity of the limiting frame. A movable clamping frame is fixedly connected to one side of each of the two limiting shells. A fixed clamping frame that cooperates with the movable clamping frame is fixedly connected to the bottom of the limiting frame. A support roller is movably connected to one side of the movable clamping frame and the fixed clamping frame. A clamping device is provided in the inner cavity of the limiting shell.

[0005] In a preferred embodiment of this invention, the clamping device includes two clamping blocks. A movable inclined plate is fixedly connected to one side of each of the two clamping blocks, and a stabilizing rod is fixedly connected to one side of each of the two movable inclined plates. Two stabilizing frames that cooperate with the stabilizing rods are fixedly connected to the inner cavity of the limiting shell. The surface of the stabilizing rod is movably connected to the inner cavity of the stabilizing frame. A spring is fixedly connected to one side of each of the two movable inclined plates. By providing the clamping device, when the support roller needs to be positioned at a specific location, the clamping device restricts the position of the support roller.

[0006] As a preferred embodiment of this utility model, the inner cavity of the limiting shell is movably connected to two extrusion column handles that cooperate with the moving inclined plate. The surface of the extrusion column handle is in contact with the surface of the moving inclined plate. The side of the extrusion column handle away from the limiting frame penetrates the limiting shell and extends to the outer side of the inner cavity of the limiting shell. By setting the extrusion column handle, when the extrusion column handle moves, it can generate an extrusion force on the moving inclined plate. The extrusion force generated by the extrusion column handle on the moving inclined plate can drive the moving inclined plate to move.

[0007] As a preferred embodiment of this utility model, a positioning frame is fixedly connected to the surface of the limiting shell, and a positioning hole is provided on the surface of the extrusion column handle to cooperate with the positioning frame. The surface of the positioning frame is movably connected to the inner cavity of the positioning hole. By setting the positioning frame and the positioning hole, when the extrusion column handle moves, it will drive the positioning hole to move along the surface of the positioning frame. The cooperation between the positioning hole and the positioning frame has a limiting effect on the movement position of the extrusion column handle.

[0008] As a preferred embodiment of this utility model, the front and rear sides of the limiting shell are fixedly connected with limiting sliding shells that cooperate with the limiting long frame. The inner cavity of the limiting sliding shell is movably connected to the surface of the limiting long frame. By setting the limiting sliding shell, when the limiting shell moves, it will drive the limiting sliding shell to move along the surface of the limiting long frame. The setting of the limiting sliding shell has a limiting effect on the movement position of the limiting shell.

[0009] As a preferred embodiment of this utility model, the front and rear sides of the inner cavity of the limiting frame are provided with a plurality of block slots for use with clamping blocks. The surface of the clamping block contacts the inner cavity of the block slot. By setting the block slot, when the limiting shell moves to the appropriate position, the squeezing column handle is released, and the restoring force generated by the spring returning to its shape will drive the clamping block to be inserted into the inner cavity of the block slot. The use of the clamping block and the block slot together has a limiting effect on the position of the limiting shell.

[0010] As a preferred embodiment of this utility model, welding rotating shells are fixedly connected to opposite sides of the two limiting long frames, and welding rotating blocks that cooperate with the welding rotating shells are fixedly connected to opposite sides of the two welding brackets. The inner cavity of the welding rotating shell is movably connected to the surface of the welding rotating block. By setting the welding rotating shell and the welding rotating block, when the welding rotating shell rotates along the surface of the welding rotating block, the support roller will rotate in a fixed position.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model solves the problem of existing support roller blanks requiring welding processing by setting up a clamping device, clamping block, movable inclined plate, stabilizing rod, stabilizing frame and spring in combination. Welding can firmly connect different parts together to form an integral structure, improving the load-bearing capacity and impact resistance of the support roller. During welding, a welding bracket is required to position the support roller. Usually, the welding bracket uses bolts to adjust the position of the clamping parts. The bolts are prone to loosening when subjected to external pressure and impact. Moreover, the installation and removal of the bolts require the use of professional tools for constant adjustment, which is time-consuming, labor-intensive and inconvenient. However, the clamping fixtures used for welding existing support roller blanks do not have components for more stable and convenient positioning of the support roller.

[0013] 2. By setting up a clamping device, the two moving inclined plates under the extrusion force will move towards each other. When the moving inclined plates move, they will drive the stabilizing rod to move along the inner cavity of the stabilizing frame. At the same time, the force generated when the clamping block moves causes the spring to undergo elastic deformation. The restoring force generated by the spring returning to its shape will drive the clamping block to be inserted into the inner cavity of the block slot. The clamping device has a limiting effect on the position of the support roller. Attached Figure Description

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, the present invention provides a welding fixture for a support roller blank, including a welding base 1 and two welding brackets 2. The bottom of the welding brackets 2 is fixedly connected to the top of the welding base 1. A limiting frame 3 is movably connected to one side of each of the two welding brackets 2. A limiting shell 4 is movably connected to the inner cavity of the limiting frame 3. A movable clamping frame 5 is fixedly connected to one side of each of the two limiting shells 4. A fixed clamping frame 6, which cooperates with the movable clamping frame 5, is fixedly connected to the bottom of the limiting frame 3. A support roller 7 is movably connected to one side of the movable clamping frame 5 and the fixed clamping frame 6. A clamping device 8 is provided in the inner cavity of the limiting shell 4.

[0022] refer to Figure 4 The clamping device 8 includes two clamping blocks 801. A movable inclined plate 802 is fixedly connected to one side of each clamping block 801. A stabilizing rod 803 is fixedly connected to one side of each movable inclined plate 802. Two stabilizing frames 804 that cooperate with the stabilizing rods 803 are fixedly connected to the inner cavity of the limiting shell 4. The surface of the stabilizing rod 803 is movably connected to the inner cavity of the stabilizing frame 804. A spring 805 is fixedly connected to one side of each movable inclined plate 802.

[0023] The above solution is adopted: by setting up a clamping device 8, when the support roller 7 needs to be positioned in a specific position, the clamping device 8 has a restrictive effect on the position of the support roller 7.

[0024] refer to Figure 4 The inner cavity of the limiting shell 4 is movably connected to two extrusion column handles 9 that cooperate with the movable inclined plate 802. The surface of the extrusion column handle 9 is in contact with the surface of the movable inclined plate 802. The side of the extrusion column handle 9 away from the limiting frame 3 passes through the limiting shell 4 and extends to the outside of the inner cavity of the limiting shell 4.

[0025] The above solution is adopted: by setting the extrusion column handle 9, when the extrusion column handle 9 moves, it can generate extrusion force on the moving inclined plate 802. The extrusion force generated by the extrusion column handle 9 on the moving inclined plate 802 can drive the moving inclined plate 802 to move.

[0026] refer to Figure 3 The surface of the limiting shell 4 is fixedly connected to the positioning frame 10, and the surface of the extrusion column handle 9 is provided with a positioning hole 11 that cooperates with the positioning frame 10. The surface of the positioning frame 10 is movably connected to the inner cavity of the positioning hole 11.

[0027] The above solution is adopted: by setting the positioning frame 10 and the positioning hole 11, when the extrusion column handle 9 moves, it will drive the positioning hole 11 to move along the surface of the positioning frame 10. The cooperation between the positioning hole 11 and the positioning frame 10 has a limiting effect on the movement position of the extrusion column handle 9.

[0028] refer to Figure 3 The front and rear sides of the limiting shell 4 are fixedly connected with limiting slide shells 12 that cooperate with the limiting frame 3. The inner cavity of the limiting slide shell 12 is movably connected to the surface of the limiting frame 3.

[0029] The above solution is adopted: by setting a limiting sliding shell 12, when the limiting shell 4 moves, it will drive the limiting sliding shell 12 to move along the surface of the limiting frame 3. The setting of the limiting sliding shell 12 has a limiting effect on the movement position of the limiting shell 4.

[0030] refer to Figure 2 The front and rear sides of the inner cavity of the limiting frame 3 are provided with several block grooves 13 that are used to cooperate with the clamping block 801. The surface of the clamping block 801 is in contact with the inner cavity of the block groove 13.

[0031] The above solution is adopted: by setting the block groove 13, when the limiting shell 4 moves to the appropriate position, the squeezing column handle 9 is released, and the restoring force generated by the spring 805 returning to its shape will drive the clamping block 801 to be inserted into the inner cavity of the block groove 13. The cooperation of the clamping block 801 and the block groove 13 has a limiting effect on the position of the limiting shell 4.

[0032] refer to Figure 2 Two limiting frames 3 are fixedly connected to opposite sides of a welding rotating shell 14, and two welding brackets 2 are fixedly connected to opposite sides of a welding rotating block 15 that works with the welding rotating shell 14. The inner cavity of the welding rotating shell 14 is movably connected to the surface of the welding rotating block 15.

[0033] Using the above scheme: by setting up a welding rotating shell 14 and a welding rotating block 15, when the welding rotating shell 14 rotates along the surface of the welding rotating block 15, the support roller 7 will rotate in a fixed position.

[0034] The working principle of this utility model:

[0035] When using the clamping fixture for welding the support roller 7 blank, which requires more stable and convenient positioning of the support roller 7, the user first moves the support roller 7 to a position where it contacts the top of the fixed clamping frame 6. Then, the user pulls the two extrusion column handles 9 toward opposite sides. When the extrusion column handles 9 move, they will cause the positioning hole 11 to move along the surface of the positioning frame 10. When the extrusion column handles 9 move, they can generate extrusion force on the moving inclined plate 802. The two moving inclined plates 802, which are subjected to extrusion force, will move toward each other. When the moving inclined plate 802 moves, it will cause the stabilizing rod 803 to move along the inner cavity of the stabilizing frame 804. At the same time, the force generated when the clamping block 801 moves causes the spring 805 to elastically deform. When the clamping block 801 has completely moved into the inner cavity of the limiting shell 4, the user pulls the moving clamping frame 5 toward the side closer to the support roller 7. When the holder 5 moves, it will drive the limiting shell 4 to move along the inner cavity of the limiting frame 3. At the same time, the limiting shell 4 will drive the limiting sliding shell 12 to move along the surface of the limiting frame 3. When the bottom of the moving clamping holder 5 is in close contact with the surface of the support roller 7, the two extrusion column handles 9 are released. The restoring force generated by the spring 805 returning to its shape will drive the clamping block 801 to be inserted into the inner cavity of the block groove 13. The cooperation of the clamping block 801 and the block groove 13 has a limiting effect on the position of the limiting shell 4 and the moving clamping holder 5. The cooperation of the fixed clamping holder 6 and the moving clamping holder 5 has a limiting effect on the position of the support roller 7. When welding, the welding rotating shell 14 can be rotated, which will drive the welding rotating shell 14 to rotate along the surface of the welding brick. At the same time, it will drive the two support rollers 7 to rotate. At this time, the clamping fixture used for welding the support roller 7 blank will achieve a more stable and convenient positioning of the support roller 7, and welding operations can be performed.

[0036] In summary, the welding fixture for this support roller blank, through the coordinated use of clamping device 8, clamping block 801, moving inclined plate 802, stabilizing rod 803, stabilizing frame 804, and spring 805, solves the problem that existing support roller blanks require welding. Welding can firmly connect different components together to form an integral structure, improving the load-bearing capacity and impact resistance of the support roller. During welding, a welding bracket is needed to position the support roller. Usually, the welding bracket uses bolts to adjust the position of the clamping parts. The bolts are prone to loosening when subjected to external pressure and impact. Moreover, the installation and removal of the bolts require constant adjustment using professional tools, which is time-consuming, labor-intensive, and inconvenient. However, the existing clamping fixtures used for welding support roller blanks do not have components for more stable and convenient positioning of the support roller.
