[0024] Reference Figure 1 to Figure 3 As shown, the embodiment of the utility model provides a forestry claw welding fixture, comprising:
[0025] The welding assembly 1000 and the horizontally arranged bottom plate 2000. The welding assembly 1000 is connected to the top of the bottom plate 2000.
[0026] The welding assembly 1000 includes two short pin rod supports 110, a short positioning pin rod 120, two long pin rod supports 130, a long positioning pin rod 140, two large pipe support plates 150, two side plate fixing assemblies 160, an end plate fixing guard 170, two large shaft sleeves 180, a small shaft sleeve 190 and a positioning guard 200. The two short pin rod supports 110 are symmetrically arranged along the Y direction; the short positioning pin rods 120 are inserted into the two short pin rod supports 110 and are used to sleeve the two large partitions 210; the two long pin rod supports 130 are symmetrically arranged along the Y direction; the long positioning pin rods 140 are inserted into the two long pin rod supports 130 and are used to sleeve the second small partition 220, the small tube 230, and the two large partitions 210 and the two first small partitions 240 sleeved on the small tube 230; the two large tube support plates 150 are symmetrically arranged along the Y direction and are used to fix and support the large tube 250; the large shaft sleeve 180 is sleeved on the long positioning pin rod 140 and is located on the end surface of the small tube 230 and the second small partition 22 0; the small shaft sleeve 190 is sleeved on the short positioning pin rod 120 and is located between the two large partitions 210; the two side plate fixing assemblies 160 are symmetrically arranged along the Y direction, and the two side plate fixing assemblies 160 are respectively used to fix and support the two side plates 260; the end plate fixing fence 170 is arranged at the front end of the bottom plate 2000, and is used to fix and support the end plate 270; the positioning fence 200 and one of the two side plate fixing assemblies 160 are located on the same side of the bottom plate 2000, and one of the two side plates 260 is against the inner wall of the positioning fence 200; the large tube support plate 150, the long pin rod support 130 and the short pin rod support 110 are arranged in sequence from front to back along the X direction. In this embodiment, the large tube support plate 150, the long positioning pin rod 140 and the short positioning pin rod 120 ensure the position accuracy requirements of the large tube 250, the small tube 230, the large partition 210, the first small partition 240 and the second small partition 220.
[0027] Specifically, in this embodiment, the large tube 250, the small tube 230, the large partition 210, the first small partition 240 and the second small partition 220 are supported and fixed by the welding assembly 1000, and then welded. This greatly improves the working efficiency, the working time is only half of the original, and the original subsequent correction and maintenance are reduced. The problem of diagonal distortion of the overall frame and the problem of eccentricity of the partition holes (the holes of the large partition 210, the first small partition 240 and the second small partition 220) are solved. In addition, a large shaft sleeve 180 and a small shaft sleeve 190 are provided to ensure the spacing between the two large partitions 210 and the spacing between the second small partition 220 and the small tube 230, solving the problem that the precision of the partition spacing is too small to ensure welding.
[0028] Furthermore, there are a plurality of end plate fixing grids 170, which are arranged at intervals along the Y direction; the back of the top of the end plate fixing grid 170 is provided with a first profiling groove 171 matching the end plate 270. The side plate fixing assembly 160 includes a side edge fixing grid 161 provided on the outside of the side plate 260 and a front end fixing grid 162 provided on the front end of the side plate 260; the inner side of the side edge fixing grid 161 is provided with a second profiling groove 1611 matching the side plate 260, and the rear side of the front end fixing grid 162 is provided with a third profiling groove 1621 matching the side plate 260.
[0029] Furthermore, a U-shaped slot 151 is provided on the top of the large tube support plate 150, and the two side walls and the bottom wall of the U-shaped slot 151 are tangent to the large tube 250. In this way, the large tube 250 can be stably and reliably limited to ensure that the large tube 250 will not shift during the welding process.
[0030] Furthermore, the present application also includes a limiting card plate 280 located between the two large tube support plates 150, and the limiting card plate 280 is used to support the two large partitions 210 and the first small partition 240; the limiting card plate 280 is provided with a fourth profiling groove 281 and a fifth profiling groove 282 along the Y direction, which are respectively matched with the large partition 210 and the first small partition 240. Specifically, the limiting card plate 280 further supports the large partition 210 and the first small partition 240 to improve the welding accuracy.
[0031] Furthermore, the short pin support 110 is provided with a through hole; the short positioning pin 120 is inserted into the through holes of the two short pin supports 110. One end of the short positioning pin 120 is against the outer wall of one of the short pin supports 110, and the other end of the short positioning pin 120 is fixedly connected to the other short pin support 110. A screw 121 is provided at one end of the short positioning pin 120 that is fixedly connected to the short pin support 110, and the screw 121 passes through the through hole and is threadedly connected to a nut, and the nut is against the outer wall of the short pin support 110. The connection structure of the long pin support 130 and the long positioning pin 140 and the connection structure of the short pin support 110 and the short positioning pin 120 are the same. The operation is convenient and quick, and the connection is more stable.
[0032] Furthermore, the welding assembly 1000 is detachably connected to the base plate 2000. The welding assembly 1000 is detachably connected to the base plate 2000 by bolts. For example, each component in the welding assembly 1000 (short pin rod support 110, long pin rod support 130, large tube support plate 150, side plate fixing assembly 160, end plate fixing grid 170 and positioning grid 200) is a movable part, and all surfaces of each component are finely milled, and threaded holes are punched at the bottom. The base plate is milled with grooves and holes at the locations where each component is installed, and then each component is fixed to the base plate by bolts. This method has two advantages. One is that a single component is small and does not need to consider the matching size, so it is easy to process; the other is that it is easy to repair. If a single component is damaged, only the single component needs to be replaced.
[0033] The process of welding using this fixture is as follows:
[0034] Place one of the side plates 260 on the side plate fixing assembly 160 and against the positioning fence 200, then place the large tube 250 on the large tube support plate 150 and make the large tube 250 against the above-mentioned side plate 260. Place the end plate 270 on the end plate fixing fence 170, and place the other side plate 260 on the side plate fixing assembly 160 and against the end of the end plate 270 and the large tube 250. Place the two large partitions 210 and the first small partition 240 in advance and place them between the two long pin rod supports 130. At this time, the front ends of the large partitions 210 and the first small partition 240 are stuck on the outer wall of the large tube 250, and the rear ends of the large partitions 210 and the first small partition 240 are located between the two short pin rod supports 110. Then, the short locating pin 120 is passed through a short pin support 110, a large partition 210, a small sleeve 190, another large partition 210 and another short pin support 110 in sequence, and the short locating pin 120 is fixed to the short pin support 110. Subsequently, the long locating pin 140 is passed through a long pin support 130, a second small partition 220, a large sleeve 180, a small tube 230, another large sleeve 180, another second small partition 220 and another long pin support 130 in sequence. Thus, the fixation of the product components is completed and the welding operation begins. After the spot welding is completed, the short locating pin 120 and the long locating pin 140 are pulled out, and the whole is taken out before full welding. The whole process effectively guarantees the product accuracy and is suitable for the welding of similar high-precision claw products.
[0035] It can be seen that this fixture can solve welding problems such as excessive spacing between partitions, eccentric holes, and diagonal distortion of products during product welding and assembly. One-time assembly and spot welding greatly improves welding efficiency and reduces subsequent shaping and repair time. It improves operating efficiency and yield; one-time assembly reduces defects such as missing or wrong assembly caused by personnel status; it is easier for novice employees to get started, which in turn reduces employee training costs.
[0036] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
