Description
Technical Field
[0001] The present application relates to the technical field of positioning tooling, and in particular to a positioning tooling for a feed screening machine. Background Art
[0002] The feed screening rod plays a vital role in the feed screening machine. The feed screening rod can ensure the uniform distribution of materials during the screening process to avoid blockage and accumulation. The screening rod also plays a pre-screening role in the feeding process, separating oversized or undersized materials in advance and reducing direct impact and wear on the screen, which not only extends the service life of the screen, but also reduces the maintenance cost of the screening machine.
[0003] By optimizing the design of the feed screen bar, you can ensure smooth flow of materials in the screen, reduce material jams and downtime. This helps to increase the overall capacity of the screen to meet production needs.
[0004] Reference Figure 1 The feed screening rod includes a screening baffle 01, and two parallel support plates 02 are welded to the bottom of the screening baffle 01. A gap is left between the two support plates 02, and the support plate 02 is arranged perpendicular to the screening baffle 01. The bottom wall of the support plate 02 is arranged in an inclined manner corresponding to the inclined screening frame. The ends of the two support plates 02 are fixedly welded with a sealing plate 03, and the bottom walls of the two support plates 02 are provided with a plug-in slot 021 near the ends. The bottoms of the two support plates 02 are welded with a connecting plate 04 for connecting to the screening frame. The connecting plate 04 matches the plug-in slot 021 and is plugged into the plug-in slot 021, and the ends of each connecting plate 04 extending out of the support plate 02 are vertically penetrated with a countersunk hole 041 for mounting bolts.
[0005] When welding the above-mentioned feed screening rods, workers are required to perform precise measurements before welding the components. The measurements before welding require a long working time, which greatly affects the work efficiency of assembling the feed screening rods. Utility Model Content
[0006] In order to improve the welding efficiency of the feed screening rod, the present application provides a positioning tool for a feed screening machine.
[0007] The present application provides a positioning tool for a feed screening machine using the following technical solution:
[0008] A positioning tool for a feed screening machine includes a support seat, a mounting seat is provided on the support seat corresponding to each connecting plate, and a screw hole is vertically opened corresponding to the countersunk hole on each mounting seat, and a connecting rib plate connecting two mounting seats is provided on the support seat, the length direction of the connecting rib plate is perpendicular to the distribution direction of the two mounting seats, and the thickness of the connecting rib plate corresponds to the gap between the two support plates, and the two support plates are both arranged to fit the connecting rib plate.
[0009] By adopting the above technical solution, when the positioning fixture is used to weld the feed screening rod, first align the countersunk holes on the two connecting plates with the screw holes and fix them to the mounting seat by bolts; then fit the support plate to the connecting rib plate, and at the same time, make the plug-in slots on the support plate correspondingly sleeved on the corresponding mounting seat. Under the top support of the connecting rib plate, the connection between the support plate and the connecting plate can be welded. The two support plates can be quickly positioned and fixed by connecting the rib plate, thereby improving the welding efficiency of the feed screening rod and the assembly accuracy. In addition, the fixture also provides a detection function. When it is necessary to conduct random inspections on the finished products, it is only necessary to sleeve the finished products on the fixture, and use the screws to jointly pierce the corresponding countersunk holes and screw holes. If the penetration is successful, the finished products can be preliminarily considered to be qualified products.
[0010] Optionally, a support plate is detachably provided on the support seat at opposite sides of the two support plates, and the support plate is limited between the support plate and the connecting rib plate.
[0011] By adopting the above technical solution, the support plate is more stably supported during the welding process by adding a support plate. Under the joint action of the support plate and the connecting rib plate, the support plate is clamped in the middle, effectively preventing the support plate from shaking and deflecting, thereby ensuring the accuracy and quality of welding. At the same time, since the support plate is detachable, the positioning tool can also adapt to screening rods of different specifications and sizes, improving the versatility of the tool.
[0012] Optionally, a plurality of stiffening plates are distributed along the length direction of the side walls facing away from the two support plates, and one right-angled side of each stiffening plate is fixedly arranged on the support plate, and the other right-angled side is arranged to fit the top wall of the support seat.
[0013] By adopting the above technical solution, the setting of the stiffening plate can enhance the supporting strength of the support plate, and can effectively improve the bending strength and rigidity of the support plate, so that it can maintain a stable supporting force even in the face of large welding stress during the welding process of the auxiliary feed screening rod. It not only reduces the possibility of deformation or damage of the support plate during long-term use, and extends the service life of the positioning tooling, but also, the fitting setting of the stiffening plate and the top wall of the support seat also enhances the stability of the entire tooling in cooperation with the support plate, thereby improving the welding efficiency and assembly accuracy of the feed screening rod.
[0014] Optionally, a plurality of slide grooves are provided on the top of the support seat in parallel along a direction perpendicular to the connecting rib plate, and the plurality of slide grooves are located between two mounting seats. A plurality of vertical rods are arranged on the bottom of each support plate along its length direction, and the vertical rods correspond to the slide grooves one by one, and the vertical rods are inserted into the corresponding slide grooves and slideably cooperate with the slide grooves. An elastic member is provided in each slide groove for applying a thrust to the vertical rod toward the connecting rib plate.
[0015] By adopting the above technical solution, the vertical rods on the support plate are correspondingly inserted into the slide grooves, and the elastic member drives the slider to apply a supporting force toward the connecting rib plate to the vertical rods, so that the support plate always presses the support plate against the connecting rib plate, reducing the possibility of shaking and deviation of the support plate, thereby improving the welding efficiency of the feed screening rod.
[0016] Optionally, a fixed block is provided at one end of each slide groove away from the connecting rib plate, and the elastic member includes a sliding block that is arranged to abut against the vertical rod and a compression spring arranged between the sliding block and the fixed block. The compression spring is located in the slide groove and abuts between the fixed block and the sliding block.
[0017] By adopting the above technical scheme and utilizing the cooperation between the compression spring and the slider, the slider is subjected to the elastic recovery characteristics of the compression spring, and the support plate is always supported to press the support plate against the connecting rib plate, thereby reducing the possibility of shaking and deviation of the support plate and improving the welding efficiency of the feed screening rod.
[0018] Optionally, a guide groove is opened on one side of the fixed block facing the sliding block along the length direction of the sliding groove, a guide rod is slidably arranged in the guide groove, the end of the guide rod extending out of the guide groove is arranged on the sliding block, and the compression spring is sleeved on the guide rod.
[0019] By adopting the above technical solution, the sliding arrangement of the guide rod and the guide groove improves the stability of the slider when sliding, thereby reducing the possibility of the slider escaping from the slide groove during the process of supporting the support plate.
[0020] Optionally, a guide surface is provided on one side of the sliding block facing the connecting rib plate corresponding to the plugging direction of the vertical rod.
[0021] By adopting the above technical solution, the setting of the guide surface makes it easy for the staff to smoothly insert the vertical rod on the support plate into the slide groove, and reduces the possibility of damage caused by interference when the vertical rod is inserted into the slide groove, thereby increasing the service life of the support plate.
[0022] Optionally, a handle is provided on the support plate, and the handle and the stiffening plate are located on the same side of the support plate.
[0023] By adopting the above technical solution, the setting of the handle makes it convenient for the staff to take the supporting plate to cooperate with the welding work.
[0024] In summary, the present application includes at least one of the following beneficial technical effects:
[0025] 1. When using the positioning tool to weld the feed screening rod, first align the countersunk holes on the two connecting plates with the screw holes and fix them to the mounting base with bolts; then fit the support plate to the connecting rib plate, and at the same time, make the plug-in slots on the support plate correspond to the corresponding mounting base. Under the top support of the connecting rib plate, the connection between the support plate and the connecting plate can be welded. The two support plates can be quickly positioned and fixed by connecting the rib plates, thereby improving the welding efficiency of the feed screening rod and the assembly accuracy. The tooling also provides a detection function. When it is necessary to conduct random inspections on the finished products, it is only necessary to set the finished products on the tooling, and use screws to jointly pierce the corresponding countersunk holes and screw holes. If the penetration is successful, the finished products can be preliminarily considered to be qualified products;
[0026] 2. By adding a support plate, the support plate is more firmly supported during the welding process. Under the joint action of the support plate and the connecting rib plate, the support plate is clamped in the middle, effectively preventing the support plate from shaking and deflecting, thereby ensuring the accuracy and quality of welding. At the same time, since the support plate is detachable, the positioning tooling can also adapt to screening rods of different specifications and sizes, improving the versatility of the tooling;
[0027] 3. The setting of the stiffening plate can enhance the supporting strength of the support plate, and can effectively improve the bending strength and rigidity of the support plate, so that it can maintain a stable supporting force even in the face of large welding stress during the welding process of the auxiliary feed screening rod. It not only reduces the possibility of deformation or damage of the support plate during long-term use, and extends the service life of the positioning tooling, but also the fitting setting of the stiffening plate and the top wall of the support seat also enhances the stability of the entire tooling in cooperation with the support plate, thereby improving the welding efficiency and assembly accuracy of the feed screening rod.
