Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, and more specifically, to a support tooling. Background Technology

[0002] A support component on an existing excavator includes a first connecting plate, a second connecting plate, and a connecting column. Both the first and second connecting plates are J-shaped, and when fixed, they form a T-shape. For ease of production, the first, second, and connecting plates are manufactured separately and then welded together. The second connecting plate is welded obliquely to the back of the first connecting plate, and the connecting column is welded to the second connecting plate. The first connecting plate has through holes at both its curved and straight sections for mating with the other components; the second connecting plate also has through holes at its curved section for mating with the other components. During welding, workers first weld the first and second connecting plates together, and then weld the connecting column together. Since both the first and second connecting plates have curved surfaces that are inconvenient to place flat, workers need to hold the second connecting plate with one hand during welding. However, both the first and second connecting plates are metal plates with a certain thickness and weight. As the working time increases, the worker's hand holding the second connecting plate is prone to shaking during the welding process, affecting the welding quality and precision, and increasing the worker's labor intensity. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model provides a support fixture, comprising a base plate, a first positioning fixture, a second positioning fixture, and a connecting column limiting assembly mounted on the base plate. Two first positioning fixtures are spaced apart, each located on one side of a second connecting plate. Each first positioning fixture has a positioning groove for positioning the first connecting plate. The bottom of the positioning groove has a first mating arc surface adapted to the arc surface of the first connecting plate, and a first positioning bolt inserted into a through hole in the first connecting plate is provided on the first mating arc surface. The second positioning fixture has a second mating arc surface for positioning the second connecting plate, and a second positioning bolt inserted into a through hole in the second connecting plate is provided on the second mating arc surface. The connecting column limiting assembly is adapted to press and limit the connecting column onto the second connecting plate. When the first connecting plate is positioned on the first positioning fixture and the second connecting plate is positioned on the second positioning fixture, the weld between the second connecting plate and the first connecting plate abuts.

[0004] Optionally, the positioning groove is located above the side of the second positioning fixture away from the connecting column limiting assembly, so that the abutment of the first connecting plate and the second connecting plate is in an inclined state.

[0005] Optionally, two second positioning bolts are provided at intervals, and the two second positioning bolts are respectively inserted into two through holes of the second connecting plate.

[0006] Optionally, the connecting post limiting assembly includes a threaded rod, an abutment strip, a support nut, and a clamping nut. The abutment strip is sleeved on the threaded rod, and the clamping nut and the support nut are both threadedly connected to the threaded rod. The clamping nut and the support nut are located on the upper and lower sides of the abutment strip, respectively, to clamp and fix the abutment strip. The abutment strip abuts against the side of the connecting post away from the second connecting plate.

[0007] Optionally, the top of the abutting strip is provided with a waist-shaped hole, and the threaded rod is inserted into the waist-shaped hole. The extension direction of the waist-shaped hole is the horizontal direction from the first positioning fixture to the threaded rod.

[0008] Optionally, the first positioning fixture includes a fixed plate and a cantilever. The fixed plate is fixedly connected to the base plate. The cantilever is bolted to the side of the fixed plate near the second positioning fixture. The cantilever is spaced apart from the base plate and is located above the second positioning fixture. The positioning groove is provided on the cantilever.

[0009] Optionally, a first driving block and a second driving block are slidably disposed on the base plate, and the cantilever is slidably connected to the fixed plate in the vertical direction; the second positioning fixture is located at the top of the second driving block, and the cantilever is located at the top of the first driving block; a lead screw is threadedly connected to the first driving block, and the lead screw is threadedly connected to the second driving block, and the lead screw is adapted to drive the first driving block and the second driving block to move so as to drive the cantilever and the second positioning fixture to rise.

[0010] Optionally, the top of the first drive block is provided with a first drive ramp, and the bottom of the cantilever is provided with a first mating ramp that fits with the first drive ramp; the top of the second drive block is provided with a second drive ramp, and the bottom wall of the second positioning fixture is provided with a second mating ramp that fits with the second drive ramp.

[0011] Optionally, a mounting shell is fixed on the base plate, and the second positioning fixture is inserted into the mounting shell and moves vertically in a directional manner.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] 1. The first connecting plate and the second positioning plate can be positioned on the first positioning fixture and the second positioning fixture respectively, and are in a pre-assembled state. During welding, it is not necessary to hold either connecting plate by hand, which reduces the labor intensity of the worker during welding. After the first connecting plate and the second connecting plate are positioned, they will not move relative to each other, which improves the welding quality and accuracy.

[0014] 2. The connecting column limiting assembly can press and limit the connecting column against the second connecting plate. On the one hand, it can play a role in pressing and limiting the first and second connecting plates. On the other hand, it can also eliminate the need to hold the connecting column by hand when welding, thus improving the convenience of welding.

[0015] 3. The height of the cantilever is higher than the height of the second positioning fixture, so that the product is tilted after positioning and placement. The worker does not need to lower his head to look at the ground, which can improve the worker's comfort during welding.

[0016] 4. When workers of different heights are working, rotating the lead screw can drive the cantilever and the second positioning fixture to rise, thereby raising the product to the most comfortable height for welding. This adapts to workers of different heights and improves their comfort during welding. Attached Figure Description

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-5 This application will be described in further detail.

[0024] Reference Figure 1 The support product, which requires welding, includes a first connecting plate, a second connecting plate, and a connecting column. Both the first and second connecting plates are J-shaped, and after fixing, they form a T-shape. The second connecting plate is obliquely welded to the back of the first connecting plate, and the connecting column is welded to the second connecting plate. The first connecting plate has multiple through holes at both its curved and straight sections to mate with other components; the second connecting plate also has two through holes at its curved section to mate with other components.

[0025] This utility model provides a support fixture, embodiment one: refer to Figure 2 and Figure 3 The support fixture includes a base plate 1, a first positioning fixture 2 and a second positioning fixture 3 mounted on the base plate 1, and a connecting column limiting assembly 4. Two first positioning fixtures 2 are spaced apart, located on opposite sides of a second connecting plate. The first connecting plate is positioned on the first positioning fixture 2; the second connecting plate is positioned on the second positioning fixture 3, with the weld between the second connecting plate and the first connecting plate abutting. The second positioning fixture 3 is located between the first positioning fixture 2 and the connecting column limiting assembly 4, which is adapted to press and limit the connecting column onto the second connecting plate.

[0026] The base plate 1 is suitable for placement on a workbench, allowing workers to perform welding operations while seated or simply by bending their heads, which is more comfortable than welding while squatting on the ground. The two first positioning fixtures 2 have identical structures; the following description uses the structure of one first positioning fixture 2 as an example.

[0027] Reference Figure 2 and Figure 3 The first positioning fixture 2 includes a fixed plate 21 and a cantilever 22. The fixed plate 21 is fixedly connected to the base plate 1 by bolts, and the first connecting plate is located on the cantilever 22. The cantilever 22 is fixedly installed on the side of the fixed plate 21 near the second positioning fixture 3 by bolts. The cantilever 22 and the base plate 1 are arranged at intervals, and the cantilever 22 is located above the second positioning fixture 3, so that the product is tilted after positioning and placement. The worker does not need to completely lower his head to look at the ground, which can improve the worker's comfort during welding.

[0028] In detail, the top of the cantilever 22 is provided with a positioning groove 23 for positioning the first connecting plate. The positioning groove 23 is located above the side of the second positioning fixture 3 away from the connecting column limiting assembly 4. The bottom of the positioning groove 23 is provided with a first mating arc surface 24 that matches the arc surface of the first connecting plate. The opposite sides of the first connecting plate abut against the groove wall of the positioning groove 23 and the fixing plate 21, respectively. The bottom of the cantilever 22 has a countersunk hole that penetrates the first mating arc surface 24. A first positioning bolt 25 is threaded into the countersunk hole. The threaded end of the first positioning bolt 25 protrudes through the countersunk hole, while the nut end of the first positioning bolt 25 does not protrude from the countersunk hole. The first positioning bolt 25 is inserted into the corresponding through hole on the first connecting plate, thereby positioning the first connecting plate and limiting its movement.

[0029] Reference Figure 2 and Figure 3 The second positioning fixture 3 is fixedly connected to the base plate 1 by bolts. The bolts fixing the second positioning fixture 3 pass through the bottom of the base plate 1 and are threadedly connected to the second positioning fixture 3. The top of the second positioning fixture 3 is provided with a second mating arc surface 31 for positioning the second connecting plate. Two notches are opened at intervals on the side of the second positioning fixture 3. The notches penetrate the second positioning fixture 3. Each notch has a bolt hole on the side near the second mating arc surface 31. The bolt hole penetrates the first positioning fixture 2 along the opening direction. A second positioning bolt 32 is threaded into each bolt hole. The bolt end of the second positioning bolt 32 protrudes from the second mating arc surface 31 through the bolt hole, so as to be positioned and inserted into the through hole of the second connecting plate to position the second connecting plate.

[0030] Reference Figure 2 and Figure 3 The connecting column limiting assembly 4 includes a threaded rod 41, an abutment strip 42, a support nut 43, and a clamping nut 44. The threaded rod 41 is threaded onto the top of the base plate 1. The abutment strip 42 is sleeved on the threaded rod 41. Both the clamping nut 44 and the support nut 43 are threadedly connected to the threaded rod 41. The clamping nut 44 and the support nut 43 are located on the upper and lower sides of the abutment strip 42 respectively to clamp and fix it. The support nut 43 supports the abutment strip 42, which abuts against the side of the connecting column away from the second connecting plate. Due to machining errors in the connecting column, the height of the abutment strip 42 and the tightness between the abutment strip 42 and the connecting column can be adjusted by adjusting the support nut 43 and the clamping nut 44, thereby achieving the effect of pressing and limiting the connecting column.

[0031] The abutment strip 42 has a waist-shaped hole at its top, and the threaded rod 41 is inserted into the waist-shaped hole. The extension direction of the waist-shaped hole is the horizontal direction from the first positioning fixture 2 to the threaded rod 41. After welding, the clamping nut 44 is loosened, and the abutment strip 42 is pulled along the extension direction of the waist-shaped hole so that the abutment strip 42 does not interfere with the removal of the product.

[0032] The implementation principle of the support fixture in this application embodiment is as follows: the first connecting plate and the second positioning plate can be positioned on the first positioning fixture 2 and the second positioning fixture 3 respectively, and are in a pre-assembled state. During welding, it is not necessary to hold either connecting plate by hand, reducing the labor intensity of the worker. The first and second connecting plates will not move relative to each other after being positioned. The connecting column limiting component 4 can press and limit the connecting column against the second connecting plate. On the one hand, it can suppress and limit the first and second connecting plates; on the other hand, it eliminates the need to hold the connecting column by hand during welding. The height of the cantilever 22 is higher than the height of the second positioning fixture 3, so that the product is tilted after positioning, and the worker does not need to completely lower their head to look at the ground, improving the worker's comfort during welding.

[0033] Example 2: Refer to Figure 4 and Figure 5 The difference between this embodiment and Embodiment 1 is that: a mounting shell 11 is fixed on the base plate 1, and the second positioning fixture 3 is inserted into the mounting shell 11 and moves vertically. A first driving block 12 and a second driving block 13 are slidably mounted on the base plate 1, and a cantilever 22 is slidably connected to a fixed plate 21 in the vertical direction; the second positioning fixture 3 is located on top of the second driving block 13, and the cantilever 22 is located on top of the first driving block 12; a lead screw 14 is threadedly connected to the first driving block 12, and the lead screw 14 is threadedly connected to the second driving block 13. The lead screw 14 is adapted to drive the first driving block 12 and the second driving block 13 to move, thereby driving the cantilever 22 and the second positioning fixture 3 to rise. When workers of different heights are working, rotating the lead screw 14 can drive the cantilever 22 and the second positioning fixture 3 to rise, thereby raising the welded product to the most comfortable height for welding, thus adapting to workers of different heights and improving the comfort of workers during welding.

[0034] Reference Figure 4 and Figure 5The fixed plate 21 has an elongated hole on the side near the cantilever 22, extending vertically. The bolts fixing the cantilever 22 pass through the elongated hole and are threaded into the cantilever 22, allowing the cantilever 22 to move stably vertically. The bottom of the first drive block 12 abuts against the top surface of the base plate 1. The top of the first drive block 12 has a first drive ramp, and the bottom of the cantilever 22 has a first mating ramp that engages with the first drive ramp. Therefore, after the lead screw 14 drives the first drive block 12 to move, it can drive the cantilever 22 to rise (without placing a product during adjustment). If the lead screw 14 is rotated in the opposite direction, the cantilever 22 will descend under its own weight. In another embodiment, a guide post is installed on each of the two fixed plates 21 by bolts. The guide post passes through the first drive block 12 for guidance, making the movement of the first drive block 12 more stable.

[0035] In detail, the mounting housing 11 includes two side plates, a front cover plate, and a rear cover plate. The two side plates are symmetrically spaced and fixedly connected to the base plate 1 by bolts; the front cover plate is located on the side of the side plate away from the fixing plate 21 and is fixedly connected to the two side plates by bolts; the rear cover plate is located on the side of the side plate close to the fixing plate 21 and is fixedly connected to the two side plates by bolts. The second driving component is located inside the mounting housing 11 and abuts against the top surface of the base plate 1. The top of the second driving block 13 is provided with a second driving inclined surface, and the bottom wall of the second positioning fixture 3 is provided with a second mating inclined surface that fits against the second driving inclined surface. Thus, the second driving component can move stably and directionally under the drive of the lead screw 14. The threaded rod 41 is threadedly installed on the top of the front cover plate.

[0036] Reference Figure 4 and Figure 5 The second positioning fixture 3 is inserted into the top of the mounting shell 11, and the first mating arc surface 24 always protrudes from the top of the mounting shell 11, thus providing stable support for the second connecting plate. The peripheral wall of the second positioning fixture 3 abuts against the front cover plate, the rear cover plate, and the two side plates, enabling the second positioning fixture 3 to move up and down stably. A rotating seat is mounted on the base plate 1, and one end of the lead screw 14 is inserted into and rotatably mounted on the rotating seat. A bearing is provided on the front cover plate, and the lead screw 14 passes through and is rotatably connected to the bearing. The lead screw 14 also passes through the rear cover plate. The end of the lead screw 14 away from the rotating seat is integrally formed with a rectangular column, facilitating its engagement with the corresponding hand crank.
